Description

Technical Field

[0001] This utility model relates to the field of eyeglass case testing technology, specifically to a device for testing the firmness of the female clasp of an eyeglass case. Background Technology

[0002] An existing eyeglass case uses a male and female buckle to achieve a snap-lock opening and closing mechanism. The female buckle is connected to the case body. The tightness of the connection between the female buckle and the case body needs to be tested to prevent the female buckle from detaching directly from the case body due to an unstable connection when the male and female buckles are separated. Therefore, it is necessary to test the firmness between the female buckle and the case body. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a device for testing the firmness of the clasp of an eyeglass case, which is tight, easy to adjust, and convenient to test, in order to address the shortcomings of the prior art.

[0004] To achieve the above objectives, the following technical solution is adopted: a device for testing the firmness of a female clasp on an eyeglass case, comprising a machine base, a positioning device for positioning a male clasp on the machine base, and a tension control device that can be raised and lowered above the positioning device. The tension control device includes a lifting platform raised and lowered on the machine base, and a tension control component fixedly mounted on the lifting platform. A hanging component is inserted through the end of the tension control component facing the positioning device. A female clasp clamping device is mounted on the top of the tension control component and hung on the hanging component. The female clasp clamping device includes a hanging rod hung on the hanging component, and a clamping positioning component and a clamping claw component are mounted on the hanging rod. The clamping positioning component is threadedly connected to the hanging rod, and the clamping claw component is directly or indirectly connected to one end of the hanging rod. The clamping positioning component has a conical portion facing the clamping claw component that abuts against the clamping claw component. The clamping positioning component moves up and down along the hanging rod and uses the conical portion to cause the clamping claw component to close to clamp the female clasp or open to release the female clasp. The tension control device sets a test tension until the female clasp and the eyeglass case body separate to achieve the firmness test of both.

[0005] Using the above technical solution, the positioning device can be a clamping device similar to a bench vise, which achieves clamping by turning a wrench. A spring can be installed between its two clamping plates to prevent over-clamping and ensure automatic return after release. The lifting platform and the machine base can also be raised and lowered using an accordion-style telescopic mechanism, controlled by a servo motor. The tension control component on the lifting platform can be programmed to continuously increase the tension until the female buckle is pulled out of the case, thus testing its maximum strength. The female buckle can be fixed to a test piece of the same material and thickness as the eyeglass case, with its two ends closed and clamped by the positioning device, and the middle... The female buckle is fixed, and the female buckle clamping device is hung on the hanging part via a hanging rod to separate the two, thus facilitating the removal of the female buckle clamping device. The cone on the clamping positioning part of the female buckle clamping device is larger at the top and smaller at the bottom. As the clamping positioning part moves downward along the thread of the hanging rod, its cone gradually pushes open the upper end of the clamping claw. At this time, the lower end of the clamping claw tightens to clamp the female buckle. When the clamping positioning part can no longer rotate, the lower end of the clamping part completely clamps the female buckle. At this time, the tension is continuously increased by the tension control component to pull the female buckle out of the eyeglass case. By reading the tension value at the time of release, the connection firmness between the female buckle and the eyeglass case is detected.

[0006] A device for detecting the firmness of a female clasp on an eyeglass case can be further configured such that: the gripper includes a gripper disc disposed on a hanging rod, the gripper disc having at least three gripper grooves circumferentially arranged, and grippers rotatably disposed within the gripper grooves; the gripper includes a clamping part and a positioning part, the positioning part abutting against the cone part to achieve clamping or releasing of the female clasp by the clamping part.

[0007] Using the above technical solution, the gripper disc is mounted on the gripper groove by means of side mounting screws. The positioning part of the gripper extends from the upper end of the gripper groove and abuts against the cone. When the cone gradually falls, when it reaches its larger end, each gripper rotates and the gripping part of the gripper moves closer to each other to clamp the female buckle. When it reaches its smaller end, each gripper rotates and the gripping part moves away from each other to release the female buckle.

[0008] A device for detecting the firmness of a female clasp on an eyeglass case can be further configured such that: the top of the clamping part is provided with a clamping groove, and the clamping groove surrounds the outer ring of the connection end between the female clasp and the eyeglass case body.

[0009] Using the above technical solution, if the clamping part is not provided, it may directly break the connection between the female buckle and the eyeglass case body due to excessive tightness when the clamping part is continuously tightened, thus affecting the accuracy of the entire test. By using the clamping groove to surround the connection between the female buckle and the eyeglass case body, it is possible to prevent the clamping part from directly clamping or even breaking the connection at this point when tightening, thereby ensuring the accuracy of the connection firmness test between the female buckle and the eyeglass case body.

[0010] A device for detecting the firmness of a female clasp on an eyeglass case can be further configured such that: the hanging rod has a hanging groove at one end near the hanging component, and the hanging groove is hung on the hanging component by a hanging rope.

[0011] Using the above technical solution, the lanyard can be formed into a loop by binding the ends together. The hanging component is shaped like a bolt with one end larger than the other, and it passes through the side of the tension control component. One end of the lanyard is hooked into the larger end of the hanging component, and the other end is hooked into the smaller end. This hanging method allows the entire buckle clamping device to be movable and adjustable, and the position of the buckle clamping device can be adjusted by the tightness of the lanyard. This allows the connection strength between the buckle and the eyeglass case to be tested at different positions.

[0012] A device for detecting the firmness of a female clasp on an eyeglass case can be further configured such that: the clamping and positioning component includes a tightening part connected to the end of the cone portion away from the clamping claw, the tightening part and the cone portion forming a gyro-shaped clamping and positioning component, and the outer peripheral surface of the tightening part is provided with anti-slip texture.

[0013] If the clamping and positioning component is directly set as a cone, since the tightness is usually adjusted by hand, it is difficult to exert force by hand when it is set as a cone. Therefore, the clamping and positioning component cannot be firmly tightened to hold the lower end of the nut tightly and make it more stable.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-6The device shown is for testing the fastness of a female clasp on an eyeglass case. It includes a machine base 1 with a positioning device 2 for positioning the eyeglass case. The positioning device 2 can be a clamping device similar to a bench vise, which is tightened by turning a wrench. A spring can be installed between the two clamping plates to prevent over-clamping and to ensure automatic return after loosening. A tension control device 3 is vertically mounted above the positioning device 2. The tension control device 3 includes a lifting platform 31 mounted on the machine base 1. The lifting between the lifting platform 31 and the machine base 1 can also be achieved using an accordion-style telescopic mechanism, i.e., servo motor control. A tension control component 32 is fixedly mounted on the lifting platform 31. A hanging component 33 passes through the end of the tension control component 32 facing the positioning device 2. The tension control component 32 on the lifting platform 31 can be programmed to continuously increase its tension until the female clasp is pulled out of the eyeglass case. A female clasp clamping device 4 is mounted on the top of the tension control component 32 and hung on the hanging component 33. The female clasp clamping device 4 includes components mounted on the hanging component 33. The hanging rod 41 on the 3rd has a hanging groove 42 at one end near the hanging member 33. The hanging groove 42 is hung on the hanging member 33 by a hanging rope 43. The hanging rod 41 is provided with a clamping and positioning member 44 and a gripper member 45. The clamping and positioning member 44 is threaded to the hanging rod 41. The gripper member 45 is directly or indirectly connected to one end of the hanging rod 41. The gripper member 45 includes a gripper disc 46 provided on the hanging rod 41. The gripper disc 46 has at least three gripper grooves 47 circumferentially arranged, and grippers 48 are rotatably arranged in the gripper grooves 47. The gripper 48 includes a gripping part 481 and a positioning part 482. The gripping positioning member 44 has a conical part 483 at one end facing the gripper 45, which abuts against the gripper 45. The positioning part 482 abuts against the conical part 483 to realize that the gripping part 481 grips or releases the female buckle. The gripping positioning member 44 includes a tightening part 484 connected to the end of the conical part 483 away from the gripper 48. The tightening part 484 and the conical part 483 form a gyro-shaped gripping positioning member 44. The outer peripheral surface of the tightening part 484 is provided with anti-slip texture 485.

[0024] like Figure 5 and Figure 6As shown, the top of the clamping part 481 is provided with a clamping groove 486. When the clamping part 481 clamps the female buckle, the clamping groove 486 surrounds the outer ring of the connection end between the female buckle and the eyeglass case body, thereby preventing the connection end between the female buckle and the eyeglass case body from being directly broken due to excessive clamping, resulting in inaccurate testing. The clamping positioning member 44 moves up and down along the hanging rod 41 and uses the cone part 483 to make the claw member 48 close to clamp the female buckle or open to release the female buckle. The tension control member 32 sets the test tension and uses the female buckle clamping device 4 to detach the female buckle from the eyeglass case body to realize the firmness test of the two. The female buckle can be fixed to a test piece of the same material and thickness as the eyeglass case, with its two ends closed and clamped by the positioning device 2, and the female buckle fixed in the middle. The clamping device 4 is hung on the hanging member 33 via the hanging rod 41 to separate the two, thereby facilitating the removal of the female buckle clamping device 4. The cone 483 on the clamping positioning member 44 in the female buckle clamping device 4 is larger at the top and smaller at the bottom. When the clamping positioning member 44 moves downward along the thread of the hanging rod 41, its cone 483 gradually pushes open the upper end of the gripper 48. At this time, the lower end of the gripper 48 tightens to clamp the female buckle. When the clamping positioning member 44 is clamped to the point where it can no longer rotate, the lower end of the clamping positioning member 44 completely clamps the female buckle. At this time, the tension control member 32 continuously increases the tension to separate the female buckle from the eyeglass case body. By reading the tension value at the time of separation, the connection between the female buckle and the eyeglass case body can be detected.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
