Description

Technical Field

[0001] The utility model relates to the technical field of spectacle frame testing devices, in particular to a high-precision nose bridge deformation testing device for spectacle frames. Background Art

[0002] The glasses frame is a bracket for mounting glasses lenses, usually made of metal, plastic, wood and other materials. The design and shape of the glasses frame vary according to the purpose and personal preference. The material and quality of the glasses frame will affect its comfort and durability. In order to ensure the strength of the nose bridge of the glasses frame, it is necessary to perform a deformation test on the nose bridge of the glasses frame. The testing method in the prior art is to fix one end of the glasses frame by a fixing device, and then place a weight on the other end of the glasses frame for a period of time to make the glasses frame displace to a certain extent, and finally remove the weight. After several seconds, observe the distance between the glasses frame after it is reset and its original position. In the prior art, a vernier caliper is usually used to measure the distance difference after the glasses frame is reset.

[0003] Existing nose bridge deformation testing devices for eyeglass frames usually use weights as counterweights, which have low accuracy and cannot change the weight of the weights in real time. The weights are also prone to scratching the lenses. Existing nose bridge deformation testing devices for eyeglass frames are inconvenient for fixing the eyeglass frames, which can easily affect the processing efficiency. In addition, the existing technology cannot simulate the nose bridge strength of the eyeglass frames at low temperatures in winter, and the test range is not comprehensive. Therefore, in view of the above problems, a high-precision nose bridge deformation testing device for eyeglass frames is proposed. Utility Model Content

[0004] The utility model aims to provide a high-precision nose bridge deformation testing device for eyeglass frames to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-precision nose bridge deformation testing device for an eyeglass frame comprises a base plate, the top of the base plate is fixedly connected to a column, the top of the column is fixedly connected to a fixing plate, the bottom inner end of the fixing plate is fixedly connected to a clamping plate, a frame body is arranged above the clamping plate, the top of the fixing plate is provided with a limiting hole penetrating the fixing plate, the inner side of the limiting hole is provided with a reciprocating rod, the bottom end of the reciprocating rod is fixedly connected to a clamping block, the outer side of the reciprocating rod is provided with a spring fixedly connected to the top inner end of the fixing plate, the top end of the reciprocating rod is fixedly connected to a handle, the top edge of the base plate is fixedly connected to a side plate, the top of the side plate is fixedly connected to a top plate, the middle of the bottom end of the top plate is fixedly connected to a telescopic rod, the bottom end of the telescopic rod is fixedly connected to a pressure sensor, the side of the pressure sensor is fixedly connected to a display, and the bottom end of the pressure sensor is fixedly connected to a rubber pad.

[0010] Preferably, the side panels are fixedly connected to the bottom edge of the top panel, and the top panel and the bottom panel have the same specifications.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the counterweight accuracy of the device is higher by setting the telescopic rod, pressure sensor, display and rubber pad. After fixing the glasses frame, the telescopic rod is started to extend, and the telescopic rod drives the pressure sensor and rubber pad to press down. When the rubber pad fits tightly with the frame body, the display starts to show pressure indication. By controlling the telescopic length of the telescopic rod, the pressure on the frame body can be controlled in real time. This design can not only improve the counterweight accuracy of the device, but also prevent the lenses on the frame body from being scratched.

[0013] 2. In the utility model, the fixing of the frame body is more convenient by setting the upright column, the fixing plate, the clamping plate, the frame body, the limiting hole, the reciprocating rod, the clamping block, the spring and the handle. When the frame body needs to be fixed, the handle is lifted, and the handle drives the reciprocating rod and the clamping block to rise. At this time, the spring is compressed by the external force, and the frame body is placed on the top of the clamping plate. Then, the handle is released, and the spring extends to drive the clamping block and the reciprocating rod to reset. The clamping block and the clamping plate clamp the frame body, and the frame body can be successfully fixed.

[0014] 3. In the utility model, the refrigerator, thermometer, box door and observation lens are provided to simulate the strength of the nose bridge of the glasses frame at low temperatures in winter. When the refrigerator is started, the temperature in the device is lowered, and the temperature reading of the thermometer can be observed through the observation lens located on one side of the box door. This design makes the test range of the device more comprehensive. BRIEF DESCRIPTION OF THE DRAWINGS
