[0002] High-abrasion-resistant sealing strips are specially designed sealing components with exceptional wear resistance. They play a crucial role in numerous industrial applications and everyday life. For high-abrasion-resistant sealing strips, their abrasion resistance is undoubtedly one of the most important indicators of product quality and performance. Given the importance of abrasion resistance, testing it is particularly necessary. Therefore, designing a testing device for high-abrasion-resistant sealing strips is essential for convenient testing during practical operation. Utility Model Content

[0010] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0011] like Figure 1-4As shown, the testing device for high wear-resistant sealing strips includes a base plate 1. In this embodiment, an electrical control box 2 is fixed on the base plate 1. The electrical control box 2 is an existing product, which can control the drive mechanism 3 to produce corresponding actions. This is an existing technology. A guide rail 8 is horizontally fixed on the base plate 1. A slider 7 is slidably connected to the guide rail 8. The slider 7 is fixedly connected to a reciprocating plate 5. A mounting shaft 12 is horizontally rotatably connected to the reciprocating plate 5. A return torsion spring 17 is provided between the mounting shaft 12 and the reciprocating plate 5. The mounting shaft 12 is fixedly connected to a placement platform 6 through a connecting plate 11. The placement platform 6 has several placement slots 6a for placing high wear-resistant sealing strips. In this embodiment... In this example, there are seven placement slots 6a; the placement platform 6 has a strip-shaped auxiliary hole 6b that communicates with the placement slot 6a; the reciprocating plate 5 has a positioning protrusion 5a that cooperates with the strip-shaped hole; two quick clamps 9 are also installed between the placement platform 6 and the reciprocating plate 5. In this embodiment, when the quick clamps 9 are released, the placement platform 6 can automatically flip upward under the action of the reset torsion spring 17; a bracket 4 is fixed on the base plate 1, and the bracket 4 has multiple test components. The base plate 1 also has a drive mechanism 3 that can drive the reciprocating plate 5 to move. In this embodiment, the drive mechanism 3 adopts an existing structure, which can make the reciprocating plate 5 move back and forth. This adopts existing technology.

[0012] The testing assembly includes a connecting block 15, a movable rod 14, a counterweight 13, and a test head 16. The connecting block 15 is fixed to the frame. The movable rod 14 is vertically and movably connected to the mounting hole 15a in the connecting block 15. The counterweight 13 is detachably fixed to the upper end of the movable rod 14. The test head 16 is detachably mounted to the lower end of the movable rod 14. The movable rod 14 has a limiting pin 14a in the middle. The connecting block 15 has a positioning notch 15c that mates with the limiting pin 14a. The connecting block 15 also has a groove for the limiting pin 14a to pass through. Through hole 15b; With this structure, the fit between the limiting pin 14a in the middle of the movable rod 14 and the positioning recess 15c and through hole 15b on the connecting block 15 is ingenious. During testing, the limiting pin 14a can be screwed into the through hole 15b. At this time, after the movable rod 14 is lowered, the test head 16 can freely contact the wear-resistant sealing strip on the placement platform 6. When not testing, the limiting pin 14a can be screwed into the positioning recess 15c to restrict the downward movement of the movable rod 14 and ensure that the test head 16 is away from the placement platform 6.

[0013] A handle 10 is also fixedly installed on the placement platform 6.

[0014] An L-shaped component 18 is also fixed on the reciprocating plate 5, and a limiting block 19 that cooperates with the connecting plate 11 is fixed on the L-shaped component 18.

[0015] When it is necessary to load or unload the wear-resistant sealing strip, release the quick clamp 9. Under the action of the return torsion spring 17, the placement platform 6 flips upward. After flipping, the connecting plate 11 will be blocked by the upper limit block 19 of the L-shaped part 18, keeping the placement platform 6 at an inclined loading and unloading angle, which makes it easy for operators to quickly and conveniently complete the replacement of the wear-resistant sealing strip. After the operation is completed, use the handle 10 to rotate the placement platform 6 downward to reset. After locking the quick clamp 9, the wear-resistant sealing strip is reliably fixed by the cooperation of the positioning protrusion 5a and the strip-shaped auxiliary hole 6b. Lower the movable rod 14 so that the test head 16 contacts the wear-resistant sealing strip. The drive mechanism 3 can drive the reciprocating plate 5 to make a smooth reciprocating linear motion along the guide rail 8 through the slider 7, which drives the sealing strip on the placement platform 6 to generate relative frictional motion with the test head 16. By setting the motion speed, reciprocating number and other parameters of the drive mechanism 3, the test cycle and friction stroke can be precisely controlled, thereby realizing the test of the wear resistance of the high wear-resistant sealing strip.

[0016] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0017] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
