[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] Reference Figures 1 to 3 The utility model proposes a detection tool based on the adhesion of an optical filter, comprising a push-pull force gauge 1 and a fixing device 2, wherein the measuring end of the push-pull force gauge 1 is connected with a pin 11; the fixing device 2 comprises a fixing plate 3 and a positioning component 4, the positioning component 4 is slidably connected to the fixing plate 3, and the positioning component 4 is provided with a plurality of mounting grooves 55 for mounting a workpiece to be tested, and a side of the mounting groove 55 facing the push-pull force gauge 1 has a detection port 56, and the detection port 56 can be aligned with the pin 11 by moving the positioning component 4.

[0024] It can be understood that the push-pull dynamometer 1 is a prior art product, which has a measuring end. When the measuring end is subjected to a push or pull force, the magnitude of the force will be displayed on the display screen. A pin 11 is connected to the measuring end, and the pin 11 is used to push off the filter adhered to the product to be tested. By reading the reading of the push-pull dynamometer 1 when the pin 11 pushes off the filter, the adhesion between the filter and the product can be determined; the fixing device 2 includes a fixing plate 3 and a positioning component 4, the fixing plate 3 is vertically arranged, the positioning component 4 is arranged on its top, and can move to a certain extent on the fixing plate 3, and the positioning component 4 has a plurality of mounting grooves 55 for mounting different products to be tested therein for testing, and the mounting groove 55 has a detection port 56 on a side facing the push-pull dynamometer 1, and the pin 11 can extend from the detection port 56 into the mounting groove 55 to detect the product to be tested, and by adjusting the position of the positioning component 4, the detection ports 56 of different mounting grooves 55 can be aligned with the pin 11 to achieve the purpose of detecting products of different models.

[0025] Reference Figures 2 to 3In one embodiment of the present application, the positioning assembly 4 includes a sliding seat 5 and two positioning screws 6. The fixed plate 3 is provided with a positioning groove 31. The sliding seat 5 is movably connected to the positioning groove 31. The sliding seat 5 is provided with a plurality of mounting grooves 55 at one end facing the push-pull dynamometer 1. The two positioning screws 6 penetrate the fixed plate 3 and respectively abut against two side surfaces of the sliding seat 5. The positioning screws 6 are rotated to make the sliding seat 5 slide along the positioning groove 31.

[0026] It can be understood that the sliding seat 5 is arranged in the adjustment groove 31 and can slide left and right in the adjustment groove 31. The adjustment screw 6 penetrates the fixed plate 3 and extends into the adjustment groove 31 and abuts against both sides of the sliding seat 5. When the position of the sliding seat 5 needs to be adjusted to the left or right, the adjustment screw 6 in that direction can be loosened first to leave adjustment space, and then the adjustment screw 6 on the other side can be screwed to gradually push the sliding seat 5 to the target position, and finally the two adjustment screws 6 are tightened at the same time to make them abut against the sliding seat 5, so as to avoid displacement of the sliding seat 5 in the subsequent test process, resulting in inaccurate readings of the push-pull dynamometer 1. Through the above arrangement, it is relatively easy to adjust and fix the position of the sliding seat 5, and the operation is simple.

[0027] Reference Figures 2 to 3 In one embodiment of the present application, the sliding seat 5 has an adjusting portion 51 and a mounting portion 52, the adjusting screw 6 abuts against the adjusting portion 51, the mounting groove 55 is set in the mounting portion 52, and a step surface 53 is formed between the adjusting portion 51 and the mounting portion 52, and the step surface 53 abuts against the adjusting screw 6 to limit the mounting portion 52 outside the adjusting groove 31.

[0028] It can be understood that the width of the adjustment portion 51 is smaller than the width of the mounting portion 52, so that a stepped surface 53 is formed at the connection between the two. The stepped surface 53 abuts against the adjustment screw 6 in the adjustment portion 51, so that the mounting portion 52 is always outside the adjustment groove 31, which facilitates the insertion of the ejector pin 11 into the detection port 56 for testing. When the ejector pin 11 pushes against the filter on the product to be tested, the mounting seat will not be displaced due to excessive force, thereby avoiding affecting the reading of the push-pull dynamometer 1.

[0029] Reference Figure 3 In one embodiment of the present application, the adjustment portion 51 is provided with a socket 54 relative to the adjustment slot 31 , and the socket 54 is plugged into the adjustment slot 31 so that the sliding seat 5 is connected to the adjustment slot 31 .

[0030] It can be understood that the setting of the socket 54 has the following advantages: it is easy to slide left and right. The sliding seat 5 is inserted into the adjustment groove 31 through the socket 54, and the sliding seat 5 can be easily slid left and right along the adjustment groove 31, which is convenient for adjusting the position; the position of the sliding seat 5 can be adjusted up and down to a certain extent. When the sliding seat 5 needs to be adjusted upward, it is only necessary to pull the socket 54 upward a little. Conversely, when the sliding seat 5 needs to be adjusted downward, the socket 54 is pressed downward a little; it is easy to disassemble, and the disassembly and installation of the plug-in connection method is very convenient, which helps users to inspect and repair parts.

[0031] Reference Figures 1 to 3 In one embodiment of the present application, an operating handle 61 is provided at the free end of the two adjusting screws 6 .

[0032] It can be understood that the operating handle 61 facilitates the user to turn the adjusting screw 6, and the operating handle 61 can also prevent the adjusting screw 6 from being completely screwed into the fixing plate 3. When the adjusting screw 6 is screwed to the bottom, the operating handle 61 will press against the fixing plate 3 to prevent further twisting.

[0033] Reference Figures 2 to 3 In one embodiment of the present application, a clearance opening 32 is provided on both sides of the fixing plate 3 corresponding to the operating handle 61 .

[0034] It can be understood that the setting of the clearance opening 32 makes it easy to leave more space for turning the adjusting screw 6, so that the adjusting screw 6 can be extended and retracted in a larger range within the adjusting groove 31, so that the sliding seat 5 has a larger adjustment range. Furthermore, the larger adjustment range means that the sliding seat 5 can be provided with a larger number of mounting grooves 55 without affecting the detection, so that more types of products to be tested can be tested.

[0035] The technical solution of the utility model is to set a slidable sliding seat 5 on the fixed plate 3, and the product to be tested is installed on the sliding seat 5. By adjusting the position of the sliding seat 5, different products to be tested are aligned with the ejector pin 11 on the push-pull force gauge 1, and the push-pull force gauge 1 is moved forward until the ejector pin 11 pushes off the filter on the product. At this time, the adhesion of the filter can be determined according to the reading displayed by the push-pull force gauge 1. The utility model can detect the adhesion of the filter and has strong compatibility. It can flexibly adjust the detection position to realize the detection of various products. At the same time, the structural design is compact and the product volume is small, which is convenient for placement on the desktop.
