Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to an optical analyzer for corneal contact lenses. Background Art

[0002] A contact lens optical analyzer is a device used to measure and evaluate the optical properties of contact lenses. These devices are usually used to measure various parameters of contact lenses, such as curvature, thickness, optical zone diameter, etc., to ensure that they meet the specified quality standards and provide an accurate wearing experience. The existing contact lens optical analyzer includes a frame, an eyepiece and a workbench are provided on the frame, a screw handle for controlling the up and down movement of the eyepiece is provided on one side of the frame, a slide for placing lenses is provided on the workbench, and the eyepiece is located directly above the slide, and two positioning columns are fixedly connected to the workbench. When the staff inspects the lens, they first place the lens on the slide, and then place the slide on the workbench with one side of the slide pressed against the two positioning columns. At this time, the staff can inspect the lens through the eyepiece. Since the existing slide is only placed on the workbench, when the operator places the slide, there is a certain stickiness between the fingers and the slide. When the operator removes his fingers, the slide may be dragged, causing it to fall, thereby causing damage to the lens on the slide.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a corneal contact lens optical analyzer.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a corneal contact lens optical analyzer, including an eyepiece, a slide and a workbench, the workbench is provided with a circular hole and a groove connecting the circular holes and capable of accommodating the slide to be embedded, the slide is detachably connected in the groove, and a plurality of positioning blocks for limiting the sliding of the slide are fixedly connected to the inner wall of the groove.

[0006] The utility model is further configured as follows: a guide groove for accommodating the positioning block to be embedded is opened on the object slide, and a plurality of limit strips are fixedly connected to the inner wall of the guide groove.

[0007] The utility model is further configured as follows: four positioning blocks are provided, and the four positioning blocks are symmetrically arranged on the inner wall of the groove.

[0008] The utility model is further configured as follows: the cross section of the positioning block is configured in a shape of a minor arc.

[0009] The utility model is further configured such that: the distance between the two positioning blocks arranged along the length direction of the groove is greater than the distance between the two limiting strips located in the same guide groove.

[0010] The utility model is further configured as follows: a V-shaped groove for accommodating the embedding of the lens is provided on the object slide.

[0011] The utility model is further configured as follows: a plurality of anti-slip strips are arranged in an array on the slide.

[0012] In summary, the utility model has the following beneficial effects: by arranging grooves and positioning blocks on the workbench, the analyzer can more effectively fix the specimen slide. Such a design not only improves the stability of the equipment, but also significantly reduces the risk of damage to the specimen slide and the lens thereon. The design of the groove allows the specimen slide to be tightly embedded therein, increasing the contact area between the specimen slide and the workbench, thereby improving the stability of the specimen slide. This tight fit reduces the possibility of the specimen slide falling off. The role of the positioning blocks further enhances the fixing effect of the specimen slide. These positioning blocks are fixed on the inner wall of the groove and can fit tightly with the corresponding parts of the specimen slide to prevent the specimen slide from sliding in the groove.

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Example:

[0020] A contact lens optical analyzer, such as Figure 1 , Figure 2 and Figure 3As shown, it includes an eyepiece 1, a slide 2 and a workbench 3. The workbench 3 is provided with a circular hole 4 and a groove 5 connecting the circular hole 4 and capable of accommodating the slide 2 to be embedded. The slide 2 is detachably connected to the groove 5. A plurality of positioning blocks 6 for limiting the sliding of the slide 2 are fixedly connected to the inner wall of the groove 5. People can insert the slide 2 into the groove 5, place the lens on the slide 2, and then perform optical analysis on the lens through the eyepiece 1, thereby completing the detection operation. By arranging the groove 5 and the positioning block 6 on the workbench 3, the analyzer can more effectively fix the slide 2. Such a design not only improves the stability of the equipment, but also The risk of damage to the slide 2 and the lens thereon is significantly reduced. The design of the groove 5 allows the slide 2 to be tightly embedded therein, increasing the contact area between the slide 2 and the workbench 3, thereby improving the stability of the slide 2. This tight fit reduces the possibility of the slide 2 falling off. The role of the positioning blocks 6 further enhances the fixing effect of the slide 2. These positioning blocks 6 are fixed on the inner wall of the groove 5 and can fit tightly with the corresponding parts of the slide 2 to prevent the slide 2 from sliding in the groove 5. Through the above-mentioned arrangement, the stability and fixing effect of the slide 2 are significantly improved, and the risk of damage to the slide 2 and the lens thereon is effectively reduced.

[0021] Specifically, Figure 2 , Figure 3 and Figure 4 As shown, a guide groove 9 for accommodating the positioning block 6 to be embedded is provided on the specimen slide 2, and a plurality of limit strips 10 are fixedly connected to the inner wall of the guide groove 9. Four positioning blocks 6 are provided, and the cross section of the positioning blocks 6 is arranged in an inferior arc shape. The four positioning blocks 6 are symmetrically arranged on the inner wall of the groove 5. Furthermore, the distance between two positioning blocks 6 arranged along the length direction of the groove 5 is greater than the distance between two limit strips 10 located in the same guide groove 9. The design of the guide groove 9 enables the positioning blocks 6 to play a guiding role when the specimen slide 2 slides into the groove 5, so that the specimen slide 2 is more stable when sliding. The four positioning blocks 6 are symmetrically arranged on the inner wall of the groove 5 , meaning that they can evenly share the weight of slide 2 and any external forces that may be generated. This even distribution reduces the possibility of slide 2 deforming or sliding due to uneven force, thereby improving its stability. The design of limit strip 10 enables positioning block 6 located on the same side to clamp slide 2, further improving the stability of slide 2. The inferior arc cross-section design allows positioning block 6 to better adapt to the shape of slide 2. This shape can provide a more fitting support, reducing the shaking space of slide 2 in groove 5. At the same time, it also facilitates people to install and remove slide 2, thereby improving detection efficiency.

[0022] like Figure 2 and Figure 3As shown, a V-shaped groove 8 for accommodating the embedding of a lens is provided on the specimen slide 2, and a plurality of anti-slip strips 7 are arranged in an array on the specimen slide 2. The design of the V-shaped groove 8 can accurately position and fix the lens, and the two sides of the V-shaped groove 8 can tightly clamp the lens to prevent it from moving or shaking during the analysis process. This design ensures the stability and accuracy of the lens during analysis, and improves the reliability and accuracy of the analysis. The provision of the anti-slip strip 7 increases the friction on the surface of the specimen slide 2, so that the operator can hold it more stably when taking or adjusting the specimen slide 2, which reduces the risk of accidental dropping or operating errors caused by hand slippage, and improves work safety and efficiency.
