Description

Technical Field

[0001] This utility model relates to the field of testing, and more specifically, it relates to a testing instrument for testing the abrasion resistance of shoe sole materials. Background Technology

[0002] In existing technology, shoes need to undergo quality inspection after production. The abrasion resistance of the shoe sole directly affects the lifespan of the shoe, so it is necessary to conduct abrasion resistance testing on the sole. This is done by subjecting the sole to friction and other treatments, and then observing the abrasion resistance of the sole to determine its abrasion resistance.

[0003] For example, the shoe sole abrasion resistance testing device disclosed in CN220708968U includes a workbench and an abrasion resistance testing mechanism mounted on the workbench. The abrasion resistance testing mechanism includes a sanding belt and a driving assembly. It also includes at least three sets of shoe sole placement mechanisms, with multiple sets of these mechanisms spaced apart along the movement direction of the sanding belt. Each shoe sole placement mechanism includes a shoe sole receiving component and a pressing component, which presses the shoe sole against the receiving component and performs abrasion resistance testing via the sanding belt. Each set of shoe sole placement mechanisms in this invention includes a first pressing plate, a second pressing plate, and a third pressing plate. The first pressing plate, the second pressing plate, and the third pressing plate correspond to different positions on the shoe sole. By adjusting the pressure exerted by the first cylinder, the second cylinder, and the third cylinder on the corresponding pressing plate, the abrasion resistance testing at different positions on the shoe sole is altered.

[0004] The aforementioned patent's outsole abrasion testing device has the following shortcomings: In actual use, the outsole of a shoe comes into contact with various road conditions, such as cement roads, asphalt roads, or gravel roads. Different road surfaces exert different frictional forces on the outsole. Using sandpaper of a single grit can only simulate one type of road condition to test the outsole's abrasion resistance, making the testing items insufficient. If it is necessary to test the outsole's abrasion resistance under different frictional forces, the sandpaper needs to be replaced, which is quite troublesome. Furthermore, in actual use, shoes do not slide on the ground, and the force and angle of different areas of the outsole are different. In summary, the operation of the above-mentioned solution may lead to the test results being less than objective.

[0005] Based on the above, the purpose of this utility model is to provide a testing instrument for inspecting the abrasion resistance of shoe sole materials, so as to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a testing instrument for inspecting the abrasion resistance of shoe sole materials. This invention uses several grinding wheels of varying coarseness, a rotating mounting frame, and a shoe plate on the mounting frame for fixing the shoe sole. Users can adjust the position of the shoe plate using a displacement mechanism to select grinding wheels of different coarseness for testing, and then drive the mounting frame to rotate via a drive mechanism, creating a scenario similar to a person running in shoes, making the abrasion resistance test of shoe soles more comprehensive and objective.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A base is included, a worktable is fixedly connected to the base, and several grinding wheel rings of different diameters are rotatably connected to the worktable. The grinding wheel rings are all of different coarseness. A support frame is slidably connected to the base, and a displacement mechanism for driving the support frame to move is provided on the base. A mounting frame is rotatably connected to the support frame, and several shoe plates are provided on the mounting frame. A drive mechanism for driving the mounting frame to rotate is provided on the support frame.

[0008] By adopting the above technical solution, when it is necessary to test the abrasion resistance of the sole, the shoe is worn on the shoe plate, or the sole is directly glued to the shoe plate. Then, the mounting frame is rotated by the drive mechanism, so that the sole comes into contact with the grinding wheel ring in a shape similar to that of a person running and rubs against each other to test the abrasion resistance. When it is necessary to change the coefficient of friction with the sole for testing, the support frame is moved by the displacement mechanism, so that the shoe plate moves between grinding wheel rings of different coarseness. This requires changing the coarseness of the grinding wheel ring and the coefficient of friction with the sole, and then the above steps are repeated to test the abrasion resistance of the sole.

[0009] The present invention is further configured such that: a slide rod is provided on the shoe plate, one end of which is fixedly connected to the slide rod, the other end of which is slidably connected to the mounting frame, and a spring is sleeved on the slide rod, with both ends of the spring being fixedly connected to the slide rod and the mounting frame respectively.

[0010] The present invention is further configured such that: a limiting rod is fixedly connected to the slide rod, and a limiting groove is provided on the mounting bracket for the limiting rod to be inserted and moved.

[0011] The present invention is further configured such that: the worktable is provided with mounting grooves in both quantity and position corresponding to the grinding wheel rings; a speed reduction block is provided in the mounting groove; a lead screw is provided on the speed reduction block, one end of which is rotatably connected to the lead screw; and the other end of the lead screw is threadedly connected to the worktable.

[0012] The present invention is further configured such that: the displacement mechanism includes a second lead screw that is rotatably connected to the base at both ends, and the support frame is threadedly connected to the second lead screw.

[0013] The present invention is further configured such that: the driving mechanism includes a motor fixedly connected to the support frame, and the output shaft of the motor is fixedly connected to the mounting frame.

[0014] In summary, this utility model has the following beneficial effects:

[0015] This invention features several grinding wheel rings of varying coarseness, a rotating mounting frame, and a shoe plate on the mounting frame for fixing the sole. Users can adjust the position of the shoe plate using a displacement mechanism to select grinding wheel rings of different coarseness for testing. A drive mechanism rotates the mounting frame, and with the help of a sliding rod and spring, it creates a simulated running motion similar to a person wearing shoes. The deceleration block and lead screw adjust the pushing resistance of the sole on the grinding wheel rings, making the abrasion resistance testing of the sole more comprehensive and objective.

[0026] Furthermore, the shoe plate 6 is provided with a slide rod 7, one end of which is fixedly connected to the slide rod 7, and the other end of the slide rod 7 is slidably connected to the mounting frame 5. A spring 8 is sleeved on the slide rod 7, and the two ends of the spring 8 are fixedly connected to the slide rod 7 and the mounting frame 5 respectively.

[0027] Furthermore, a limiting rod 9 is fixedly connected to the slide rod 7, and a limiting groove 10 is provided on the mounting bracket 5 for the limiting rod 9 to be inserted and moved.

[0028] Furthermore, the worktable 2 is provided with mounting slots 11 in number and position corresponding to the grinding wheel rings 3. The mounting slots 11 are provided with speed reduction blocks 12, which are made of wear-resistant rubber composite. The speed reduction blocks 12 are provided with a lead screw 13 at one end that is rotatably connected to them, and the other end of the lead screw 13 is threadedly connected to the worktable 2.

[0029] Furthermore, the displacement mechanism includes a second lead screw 14, both ends of which are rotatably connected to the base 1, and a support frame is threadedly connected to the second lead screw 14.

Then, the mounting frame 5 is rotated by the motor 15. With the help of the slide rod 7 and the spring 8, the sole comes into contact with the grinding wheel ring 3 in a shape similar to that of a person running, and they rub against each other to test the abrasion resistance.
