Lens static test fixture

Abstract

This utility model belongs to the field of lens static placement experiment technology, and discloses a lens static placement experiment fixing frame, including a base plate, two side plates, and multiple insertion plates. The two side plates are spaced apart on the base plate along its width. This lens static placement experiment fixing frame has several insertion slots on the facing sides of both side plates, allowing multiple insertion plates to be selectively inserted into these aligned slots. This creates a placement area between any two adjacent insertion plates, which can be adjusted according to the lens specifications, improving space utilization and ensuring aesthetically pleasing lens placement without collisions. Furthermore, by providing a limiting rod corresponding to each insertion slot on at least one side plate, the limiting rod can extend into the insertion slot under the elastic force of an elastic element, allowing one end of the limiting rod to limit the insertion plate, effectively preventing the insertion plate from detaching from the insertion slot during the experiment.

Description

Technical Field

[0001] This utility model relates to the field of lens static testing technology, and in particular to a lens static testing fixture. Background Technology

[0002] Lens static placement tests primarily evaluate the stability and reliability of lenses in a non-operating state, ensuring that lenses maintain stable performance after prolonged storage or transportation. In existing technologies, multiple lenses are typically placed on a tray during static placement tests. Since all lenses are placed in a common area, collisions between them can occur during the test, affecting the accuracy of the results. Furthermore, the lenses are placed haphazardly, hindering efficient use of tray space. Utility Model Content

[0003] The purpose of this utility model is to provide a lens static experimental fixing bracket that can prevent lenses from colliding with each other, and the lenses are arranged in an aesthetically pleasing manner, thereby improving space utilization.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Lens static test fixture, including:

[0006] Base plate;

[0007] Two side plates are spaced apart on the base plate along the width direction, and each of the two side plates has a plurality of insertion slots spaced apart along the length direction of the base plate on the facing sides, and the insertion slots on the two side plates are aligned one by one.

[0008] Multiple plug-in boards, each of which can be selectively plugged into the plug-in slots aligned on two side plates, so that a lens placement area is formed between any two adjacent plug-in boards;

[0009] An elastic component corresponding to at least one of the insertion slots on the side plate, the elastic component including a limiting rod and an elastic element, the limiting rod being elastically connected to the side plate through the elastic element, the elastic element being used to drive the limiting rod to extend into the corresponding insertion slot, so that one end of the limiting rod limits the insertion plate.

[0010] As an alternative, at least one end face of the plug-in plate is provided with a limiting groove along the width direction of the base plate, and one end of the limiting rod can be inserted into the limiting groove.

[0012] The outer circumferential surface of the limiting rod is provided with a boss and is slidably disposed in the sliding hole. The elastic element is disposed in the countersunk hole and the two ends of the elastic element elastically abut against the boss and the bottom of the countersunk hole, respectively.

[0013] As an alternative, the elastic component further includes a fastener disposed at the other end of the limiting rod and capable of abutting against the side plate to prevent the limiting rod from dislodging from the sliding hole.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-5 As shown, this utility model embodiment provides a lens static experimental fixing bracket, which includes a base plate 1, two side plates 2 and multiple plug-in plates 3. Two side plates 2 are spaced apart on the base plate 1 along its width. Each side plate 2 has several insertion slots 21 spaced apart along the length of the base plate 1 on its facing sides. These insertion slots 21 on the two side plates 2 are arranged in a one-to-one correspondence, meaning that the multiple insertion slots 21 on one side plate 2 correspond one-to-one with the multiple insertion slots 21 on the other side plate 2 and are aligned. Insertion plates 3 can be inserted into the aligned insertion slots 21 on the two side plates 2. By selectively inserting multiple insertion plates 3 into the aligned insertion slots 21 on the two side plates 2, a placement area is formed between any two adjacent insertion plates 3. The lens 100 is placed within this placement area, resulting in an aesthetically pleasing arrangement of the lens 100 and preventing collisions. Furthermore, depending on the specifications of the lens 100, multiple insertion slots 21 can be spaced between the two insertion plates 3 to allow for adjustment of the placement area according to the specifications of the lens 100. It is understood that the number of insertion plates 3 is less than the number of insertion slots 21 on each side plate 2.

[0039] To ensure a secure connection between the plug plate 3 and the plug slot 21 during the experiment, at least one side plate 2 is provided with an elastic component 4 corresponding to the plug slot 21 on it. The elastic component 4 includes a limiting rod 41 and an elastic element 42. The limiting rod 41 is elastically connected to the side plate 2 through the elastic element 42. The elastic element 42 is used to drive the limiting rod 41 into the corresponding plug slot 21 so that one end of the limiting rod 41 limits the plug plate 3.

[0040] This lens static test fixture has several insertion slots 21 on the opposing sides of the two side plates 2. Multiple insertion plates 3 can be selectively inserted into the aligned insertion slots 21 on the two side plates 2, so that any two adjacent insertion plates 3 form a placement area. The placement area can be adjusted according to the specifications of the lens 100, which improves space utilization and makes the lens 100 look aesthetically pleasing without collisions between them. In addition, by setting a limiting rod 41 on at least one side plate 2 corresponding to each insertion slot 21, the limiting rod 41 can extend into the insertion slot 21 under the elastic force of the elastic member 42, so that one end of the limiting rod 41 can limit the insertion plate 3, effectively preventing the insertion plate 3 from coming out of the insertion slot 21 during the experiment.

[0041] Optionally, such as Figures 3-5 As shown, at least one end face of the plug-in plate 3 is provided with a limiting groove 31 along the width direction of the base plate 1. One end of the limiting rod 41 can extend into the plug-in groove 21 and be inserted into the limiting groove 31 on the plug-in plate 3. This structure allows the plug-in plate 3 and the limiting rod 41 to be limited by a snap-fit ​​method, which further improves the connection stability of the plug-in plate 3.

[0042] Specifically, at least one side plate 2 has a countersunk hole and a sliding hole at the bottom of the countersunk hole that passes through the side plate 2. The center lines of the countersunk hole and the sliding hole are perpendicular to both side plates 2. The outer circumferential surface of the limiting rod 41 has a boss 411 and is slidably disposed in the sliding hole. The elastic member 42 is disposed in the countersunk hole and its two ends elastically abut against the boss 411 and the bottom of the countersunk hole, respectively. The elastic member 42 abuts against the boss 411 to give the limiting rod 41 a force to move toward the plug plate 3, so that the limiting rod 41 can be kept in the state of being engaged with the limiting groove 31.

[0043] Optionally, the elastic element 42 can be selected as a spring.

[0044] When the insertion plate 3 is not installed in the insertion slot 21, in order to prevent the limiting rod 41 from being dislodged from the sliding hole under the force of the elastic member 42, the elastic component 4 also includes a fastener 43. When the limiting rod 41 is slidably installed in the sliding hole, the other end of the limiting rod 41 extends out of the sliding hole, and the fastener 43 is installed at the other end of the limiting rod 41. Under the force of the elastic member 42, the limiting rod 41 can abut against the side plate 2 to limit the limiting rod 41.

[0045] Specifically, the other end of the limiting rod 41 is provided with an external thread, and the fastener 43 consists of two nuts 431 that match the external thread. The two nuts 431 are screwed onto the other end of the limiting rod 41. This structure is simple, easy to install and use, and can reduce costs.

[0046] Optionally, to facilitate the smooth insertion of the plug plate 3 into the plug slot 21, an inclined surface 412 is provided at one end of the limiting rod 41 facing the plug plate 3. The inclined surface 412 is located on the side of the limiting rod 41 away from the base plate 1. During the insertion of the plug plate 3 into the plug slot 21, the plug plate 3 can abut against the inclined surface 412, so that the plug plate 3 can drive the limiting rod 41 to overcome the elastic force of the elastic member 42 and retract it into the countersunk hole through the inclined surface 412. This structure allows the plug plate 3 to be installed smoothly without manually pulling the limiting rod 41 to make way.

[0047] To prevent the limiting rod 41 from rotating, optionally, the outer circumferential surface of the limiting rod 41 is provided with a tangent 413, and the sliding hole is provided with a plane. When the limiting rod 41 is slidably disposed in the sliding hole, the tangent 413 and the plane slide against each other.

[0048] Optionally, flexible patches are provided on both sides of each plug plate 3 along the length of the base plate 1. By providing flexible patches on the sides of the plug plate 3, the flexible patches can act as a buffer when the lens 100 collides with the plug plate 3.

[0049] Alternatively, the flexible patch can be glued to the side of the plug-in plate 3.

[0050] Optionally, the side plate 2 and the bottom plate 1 are connected by screws, which makes the connection between the side plate 2 and the bottom plate 1 convenient.

[0051] Optionally, the base plate 1, side plate 2 and plug plate 3 are all made of POM (i.e., white plastic steel). White plastic steel is relatively lightweight and can reduce the weight of the overall structure.

[0052] Of course, elastic components 4 can also be provided on both side plates 2, and limiting grooves 31 can be provided on both ends of the plug plate 3. The limiting rods 41 on both sides can limit the two ends of the plug plate 3, which can further improve the connection stability of the plug plate 3.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
