Technical background: optical glass is made of high purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium oxide in a particular formula mix, high temperature melting in the platinum crucible, stir well with ultrasonic, to bubble; Then after a long period of time slowly cooling, lest produce internal stress in the glass block. After cooling the glass block, must go through optical instrument to measure, and in the process of testing the lens surface, not accurate description of the radian of the lens to linear, there is a huge error. Therefore, invented a kind of optical lens surface shape detection device it is necessary to solve the above problem. Technical implementation elements: the purpose of the utility model is to provide an optical lens surface shape detection device, in order to solve the above technical background in the questions. To achieve the above purpose, the utility model provides the following technical scheme: an optical lens surface shape detection device, including the base, the top of the base has described coaming, described coaming inside sets foot pole, described foot pole lateral has a slider, described the slider with internal roller, roller lateral has described connecting rod, described the inside wheel with bearing, mentioned at the bottom of the slide block has a connection piece, top of the connection piece has described dynamic block, described in the dynamic block with internal hole, described in the dynamic block side is equipped with a fixed screw, mentioned at the bottom of the moving block is equipped with lifting lever, described the lifting lever both equipped with convex block, as described in top of the convex block has spring, described at the bottom of the lifting rod is equipped with rubber block, described the base surface with stents, described in the article fixed with fixed block on both sides. Optimization, described in the number of roller set to four, wheel match the ruler bar, described as described connecting rod connected to the sliding block is fixed, described the bearing inside an qualified rod, described qualified rod and connection rod fixed connection. , described the selection of pole number set to two, lifting lever stated and moving piece of fixed connection. Optimization, described the fixed screw match the hole at one end, and described the spring connected to the convex block is fixed at one end, and described the spring at the other end connected to the connection piece of fixed. Optimization, described in the foot pole match the coaming, described in the piece with the base fixed connection, as described in article fixed at both ends are connected to the fixed block is fixed, the article described the fixed made of rubber materials. Optimization, described in the 'surface with the scale line. Technical effect and advantages of the utility model, the utility model through an elevating rod, is advantageous to the surface traces of the drawing in the drawing, which is convenient for drawing other trials, move the slider to drive connection piece of mobile, connection piece drive the lifting lever to move, when lifting lever floor come into contact with the lens, if the condition of the lens surface is curved, lifting lever will be raised, thereby lifting rod drives the convex block to compress the spring, spring contraction, lifting lever to drive the move inside a brush, draw a diagram on the drawing, spring increase rubber block with contact lens effect, avoid contact with the lens rubber blocks is less than, by article has fixed, is conducive to fixed on the lens, would need to detect optical lens placed at the top of the base, pull up the fixed the optical lens on the base surface, so as to avoid the lens to move. Figure 1 illustrated instructions for overall structure diagram of the utility model; Figure 2 for overall overlooking the structure diagram of the utility model; Figure 3 for the utility model in figure 1 A, enlarge figure of structure. Figure 4 for the utility model of the structure of part B in figure 1 enlarge figure; Base figure: 1, 2 coaming, 3 feet, pole, 4 slides, roller 5, 6, 8 connection block, connecting rod, 7 bearing dynamic block 9, 10, 11 a fixed screw hole convex block, lifting lever of 12, 13, 14, 15 rubber spring, block, article 16 fixed, 17 fixed block. Concrete implementation way of the following will be combined with the appended drawings of the utility model implementation, this utility model implementation case clearly and completely describe the technical scheme of obviously, described the implementation of the case is just a part of the utility model implementation example, rather than the implementation of all cases. Based on the example of the utility model, the field common technical personnel under the premise that did not make a creative labor for all other cases, all fall within the scope of protection of the utility model. The utility model provides a as shown in figure 1 4 type of an optical lens surface detection device, including base 1, described the base 1 at the top of the coaming 2, described coaming inside an feet rod 3, 2 feet rod 3 lateral described with sliding block 4, described the slider 4 with internal roller 5, described roller 5 lateral has 6, link rod roller 5 stated inside a bearing 7, described the slider at the bottom of the 4 sets connected pieces of eight, described the connection piece of top of the 8 has 9, described move 9 with internal hole is 10, 9 side has a fixed screw described 11, described move 9 is equipped with lifting lever at the bottom of the 12, on both sides of the lifting rod 12 are described with convex block 13, described in the convex block at the top of the spring 13 14, described 12 at the bottom of the lifting rod is equipped with rubber piece of 15, described the base 1 surface with fixed article 16, the article described the fixed 16 both have a fixed block 17. Described roller number 5 set to four, described roller 5 match the ruler bar 3, described the connection rod 6 and slide block 4 fixed connection, 7 inside an qualified rod bearing, described described limit 6 fixed connection rod and connection rod, described 12 number set to two lifting lever, convenient in the same drawing a line, ensure the accuracy of line, lifting lever stated 12 and 9 fixed connection, described the fixed screw end match the hole is 10, 11 described 14 one end connected to the convex block 13 fixed spring, described the spring 14 at the other end connected to the connection piece of 8 fixed, spring 14 increased rubber block 15 contact with lens effect, avoid contact with the lens is less than 15 rubber blocks, described feet 3 match the coaming 2, as described in 1 piece of 17 with the base fixed connection, as described in article fixed 16 both ends fixed connection with the fixed block 17, article described fixed 16 made of rubber materials, described in the foot lever 3 surface with the scale line. This practical work: will need to detect optical lens placed in the top of the base 1, pull up the fixed 16 to optical lenses 1 surface on the base, so as to avoid the lens movement, in the coaming 2 surface with drawings, then brush through hole is 10, one end of the brush contact with drawings, using fixed screw 11 to fixed hole 10 internal brushes, at this point, the hand to push the slider in 4 feet 3 surface mobile, roller in 5 feet 3 surface turning, link rod and qualified rod to fixed roller 5, 6 and convenient sliding block in 4 feet 3 surface moving, sliding block 4 drives the connecting block 8 movement, connection piece of 8 driven lifting lever to 12, when lifting rod 12 floor contact lenses, if the condition of the lens surface is curved, 12 lifts the lifting rod, thus lifting rod drives the convex block 12 13 to compress the spring 14, spring 14 contraction, lifting lever to 12 lead move 9 internal brushes, draw a diagram on the drawing, spring 14 increased rubber block 15 contact with lens effect, avoid contact with the lens is less than 15 rubber blocks, convenient to other test was carried out on the drawing. End should be: the above is only for the optimization of the utility model example, are not used to limit the utility model, although in reference to the example of this utility model in detail, for the technical personnel in the field of it still can be implemented on the foregoing cases recorded by the technical scheme, modified or to some of the technical characteristics of equivalent replacement, all within the spirits and principles of the utility model, of any modifications, equivalent replacement, improvement, etc. , shall be included within the scope of protection of the utility model.
