Description

Technical Field

[0001] This utility model relates to the field of lens testing devices, and in particular to a clamping structure for lens testing. Background Technology

[0002] Currently, in the production process of dental surgical microscopes, the assembled lenses need to be inspected before leaving the factory. One of these inspections is of the lens elements. In existing technology, the microscope is fixed to a specific support, with a stage on one side for placement. This stage is movable to move the specimen under the microscope for inspection. The stage in these technologies is often simply a platform with a through-hole for placing the lens, and a support on the inner wall of the through-hole to support the specimen. During the movement of the stage, the specimen is not fixed within the through-hole, resulting in friction with the support, which can cause unintended scratches on the specimen surface, affecting the quality of the lens. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a clamping structure for lens inspection.

[0004] This utility model is achieved by the following technical solution: a clamping structure for lens testing, including a loading platform, a through hole is opened on the loading platform as a receiving hole for placing the sample, and a plurality of clamping components are provided on the inner wall of the receiving hole. When the sample is placed in the receiving hole, the clamping components abut against the edge of the sample.

[0005] Several clamping assemblies are evenly distributed on the sidewall of the receiving hole along the circumferential direction. Each clamping assembly includes a triggering part and a clamping part. The triggering part is connected to the clamping part and is respectively disposed on the inner wall of the receiving hole. The sample contacts the triggering part, and the triggering part drives the clamping part to abut against the inner wall of the receiving hole.

[0006] An installation groove is formed on the side wall of the receiving hole along the depth direction of the receiving hole, and the trigger part and the clamping part are disposed in the installation groove.

[0007] The triggering part includes a trigger tongue, which is rotatably connected to the inner wall of the mounting groove. A torsion spring is provided between the trigger tongue and the inner wall of the mounting groove. The clamping part is provided on the trigger tongue. When the trigger tongue rotates, the clamping part extends from the trigger tongue and abuts against the edge of the sample.

[0008] The trigger tongue has a receiving groove, and the clamping part is located in the receiving groove. When the trigger part rotates, the clamping part pops out from the receiving groove and abuts against the edge of the sample.

[0009] The clamping part includes a clamping tongue, and a clamping shaft is provided in the receiving groove. The clamping shaft is located at the end of the receiving groove and is positioned at the end of the receiving groove away from the torsion spring. The end of the clamping tongue passes through the clamping shaft, and a spring is provided between the clamping shaft and the bottom of the receiving groove.

[0010] A transition surface is provided between the trigger tongue and the receiving groove, and the sample is in contact with the transition surface.

[0011] Compared to existing technologies, in this invention, after the sample is placed in the receiving hole, it first contacts the transition surface. Due to the weight of the sample, the trigger tongue rotates, at which point the torsion spring begins to store energy. As the trigger tongue rotates, its end face protrudes from the receiving groove, and the clamping tongue pops out directly to clamp the sample against its side edge. The sample is thus held within the receiving hole, preventing abnormal movement during the entire transport process and reducing the possibility of wear during transport. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] Reference Figure 1-3A clamping structure for lens inspection includes a loading stage 1 with a through hole serving as a receiving hole 11 for placing a sample. Several clamping components 2 are provided on the inner wall of the receiving hole 11. When the sample is placed inside the receiving hole 11, the clamping components 2 abut against the edge of the sample. The clamping components 2 are evenly distributed along the circumference of the receiving hole 11 on its sidewalls. Each clamping component 2 includes a trigger part 21 and a clamping part 22, connected to each other and respectively located on the inner wall of the receiving hole 11. The sample contacts the trigger part 21, causing the trigger part 21 to drive the clamping part 22 to abut against the inner wall of the receiving hole 11. When the sample (lens) is placed inside the receiving hole 11, it falls with the sample, and the edge of the sample contacts the trigger part 21. The gravity of the sample causes the trigger part 21 to rotate, and as the trigger part 21 rotates, the clamping part 22 can pop out from the trigger part 21 to abut against the edge of the sample. When the sample comes into contact with the triggering part 21, the triggering part 21 provides a certain supporting effect, while the clamping part 22 abuts against the edge of the sample, so that the sample is clamped by the clamping part 22 to form a clamping effect. In this way, the sample will not move abnormally during the entire movement process, thus reducing the possibility of abnormal movement of the sample during the entire transfer process, and reducing the possibility of wear or scratches on the sample during the transfer process.

[0018] A mounting groove 23 is formed on the side wall of the receiving hole 11 along the depth direction of the receiving hole 11 for mounting the trigger part 21 and the clamping part 22. Specifically, the trigger part 21 and the clamping part 22 are disposed within the mounting groove 23. The trigger part 21 includes a trigger tongue 211, which is rotatably connected to the inner wall of the mounting groove 23. A torsion spring is provided between the trigger tongue 211 and the inner wall of the mounting groove 23. The clamping part 22 is disposed on the trigger tongue 211. When the trigger tongue 211 rotates, the clamping part 22 extends from the trigger tongue 211 and abuts against the edge of the sample. A receiving groove is formed on the trigger tongue 211, and the clamping part 22 is disposed within the receiving groove. When the trigger part 21 rotates, the clamping part 22 pops out from the receiving groove and abuts against the edge of the sample. The clamping part 22 includes a clamping tongue 221. A clamping shaft is provided in the receiving groove, located at the end of the receiving groove away from the torsion spring. The end of the clamping tongue 221 passes through the clamping shaft, and a spring 222 is provided between the clamping shaft and the bottom of the receiving groove. When the torsion spring is not subjected to external force, it drives the trigger tongue 211 to rotate upward until the trigger tongue 211 abuts against the end of the mounting groove 23. That is, the trigger tongue 211 will not completely enter the mounting groove 23. If the sample enters, it will contact the trigger tongue 211. As the sample falls, it can drive the trigger tongue 211 to rotate. As the trigger tongue 211 leaves the mounting groove 23, the clamping tongue 221 pops out from the trigger tongue 211, and finally forms an approximately perpendicular relationship with the trigger tongue 211, thus clamping the sample against the edge. When the sample is placed in the receiving hole 11, it first contacts the transition surface 24. Due to the weight of the sample, the trigger tongue 211 rotates, and the torsion spring begins to store energy. As the trigger tongue 211 rotates, its end face protrudes from the receiving groove, and the clamping tongue 221 pops out directly to clamp the sample against its side edge. At this time, the sample is clamped in the receiving hole 11, preventing abnormal movement of the sample during the entire transfer process and reducing the possibility of wear during transfer.

[0019] In this embodiment, a transition surface 24 is provided between the trigger tongue 211 and the receiving groove, and the sample contacts the transition surface 24. The transition surface 24 acts as a guide to ensure that the trigger tongue 211 opens correctly when the sample contacts it. This reduces the possibility of jamming and ensures that the sample can be clamped, preventing abnormal movement of the sample during the entire transfer process and reducing the possibility of wear on the sample during transfer.

[0020] Compared with the prior art, the sample of this utility model is clamped in the receiving hole 11, so that the sample will not move abnormally during the entire transfer process, thereby reducing the possibility of wear and tear on the sample during the transfer process.

[0021] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
