Description

Technical Field

[0001] This utility model belongs to the field of shoe sole quality inspection technology, and in particular relates to a shoe sole abrasion resistance testing device. Background Technology

[0002] The sole is a part of a shoe made of materials such as rubber, plastic, rubber-plastic composites, and recycled leather. During the manufacturing process of soles, in order to evaluate their abrasion resistance in actual use and ensure the lifespan of the shoes and the user experience of consumers, abrasion resistance testing equipment is used to test the abrasion resistance of the soles.

[0003] For example, the shoe sole abrasion resistance testing device disclosed in the utility model with authorization announcement number CN208537329U includes a base, a frame, and a friction area set on the frame. The frame is set above the base, and a shoe fixing device is provided on the frame to allow the shoe sole to contact the friction area. A reciprocating sliding device is provided on the base below the frame to allow the frame to slide back and forth. Several road surface materials are laid on the friction area along the sliding direction of the frame. The reciprocating sliding distance of the frame is consistent with the length of the friction area. However, in the application of this technical solution, the shoe sole sizes are not the same due to the influence of the users. People of different ages, body types, and genders experience different degrees of wear on the soles of their shoes. There is a technical problem that it is not possible to use different sizes of shoe soles for abrasion resistance testing to accurately obtain abrasion resistance test data for different sizes of shoe soles. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a shoe sole abrasion resistance testing device, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a shoe sole abrasion resistance testing device, comprising a frame, and further comprising: a positioning plate disposed at the middle position of the top of the frame, a frame disposed at the middle position of the top of the positioning plate, a placement groove disposed at the middle position inside the positioning plate, limit blocks disposed on both sides inside the placement groove, a friction testing mechanism disposed between the two ends inside the frame, adjustment plates disposed on both sides of the top of the positioning plate, a reserved groove disposed inside the adjustment plate, a positioning stud disposed at the middle position of both sides of the top of the positioning plate, the positioning stud penetrating the interior of the reserved groove, a lifting eye nut disposed outside the positioning stud on the top of the adjustment plate, and a stabilizing component disposed at the top of the inner side of the frame.

[0007] Furthermore, one side of the bottom of the adjustment plate is fixedly connected to the top of the limiting block, and the positioning studs are symmetrically arranged on the top of the positioning plate.

[0008] Furthermore, the diameter of the positioning stud is smaller than the inner width of the reserved groove, and the adjusting plate can move horizontally on the outside of the positioning stud on the top of the positioning plate.

[0009] Furthermore, the friction testing mechanism includes a rotating shaft, which is rotatably connected between the two ends inside the frame. A rotating cylinder is provided outside the rotating shaft, and a friction belt is provided between the outer ends of the rotating cylinder. A servo motor is provided on one side of the rear end of the frame. The rotating shafts are arranged at equal intervals between the two ends inside the frame. One side of the rear end of the rotating shaft penetrates through one side of the rear end inside the frame and is connected to the output end of the servo motor.

[0010] Furthermore, the stabilizing component includes a limiting pressure plate, which is disposed at the top of the placement slot. A lifting guide rod is disposed at the middle position of the top of the limiting pressure plate. A through hole is disposed at the middle position of the top of the inner frame. The top of the lifting guide rod passes through the interior of the through hole. A limiting block is disposed at the top of the lifting guide rod. A rubber pad is disposed at the bottom of the limiting pressure plate. A compression spring is disposed outside the lifting guide rod between the top of the inner frame and the limiting pressure plate.

[0011] Furthermore, the diameter of the lifting guide rod is smaller than the inner diameter of the perforation, the top end of the compression spring is fixedly connected to the top end of the frame, and the bottom end of the compression spring is fixedly connected to the top end of the limiting pressure plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model features an adjustment assembly between the top two sides of the positioning plate and the top of the limiting block. During use, loosening the eye nut causes the adjustment plate to move in opposite directions on the top of the positioning plate, which in turn causes the limiting block to move in opposite directions within the placement groove. This adjusts the length and width of the placement groove. After adjusting to the appropriate shoe sole size, tightening the eye nut secures the adjustment plate and fixes the limiting block. This allows for convenient, quick, and stable adjustment of the shoe sole placement space to accommodate different shoe sole sizes requiring abrasion resistance testing, further improving the device's economic efficiency.

[0014] 2. This utility model has a stabilizing component set at the top inside the frame. When in use, after the shoe sole is placed inside the placement groove, the compression spring pushes the limiting pressure plate down to press against the top of the positioning plate, so as to achieve the purpose of laying the shoe sole flat and limiting it inside the placement groove. A rubber pad is used to protect the bottom of the limiting pressure plate and the shoe sole, and the lifting guide rod is used to support and stabilize the compression spring. This avoids the shoe sole being bent by the friction belt during the test, and also prevents excessive compression that would cause the shoe sole and the friction belt to fit too tightly, thus affecting the accuracy of the test results. It is highly feasible. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4As shown, this utility model is a shoe sole abrasion resistance testing device, including a frame 1, and further including: a positioning plate 2 provided at the middle position of the top of the frame 1, a frame 4 provided at the middle position of the top of the positioning plate 2, a placement groove 14 provided at the middle position inside the positioning plate 2, and limiting blocks 19 provided on both sides inside the placement groove 14. The shoe sole to be tested for abrasion resistance is positioned by the placement groove 14, and the two sides of the shoe sole are limited by the limiting blocks 19. The two ends inside the frame 1 are rotatably connected by a rotating... A rotating shaft 15 is provided on the outside of the rotating shaft 15, and a friction belt 6 is provided between the outer sides of the rotating shaft 15. A servo motor 10 is provided on one side of the rear end of the frame 1. The rotating shaft 15 is arranged at equal intervals between the two ends inside the frame 1. One side of the rear end of the rotating shaft 15 passes through the rear end of the frame 1 and is connected to the output end of the servo motor 10. The servo motor 10 drives the rotating shaft 15 to rotate the rotating shaft 16 in both directions, which in turn drives the friction belt 6 to move back and forth to rub the sole of the shoe, so as to test the abrasion resistance of the sole.

[0024] As a further implementation of this embodiment, such as Figure 1-4 As shown, adjustment plates 5 are provided on both sides of the top of the positioning plate 2. One side of the bottom of the adjustment plate 5 is fixedly connected to the top of the limiting block 19. A reserved groove 7 is provided inside the adjustment plate 5. A positioning stud 18 is provided at the middle position of both sides of the top of the positioning plate 2. The positioning studs 18 are symmetrically arranged on the top of the positioning plate 2. The positioning studs 18 penetrate the interior of the reserved groove 7. The diameter of the positioning stud 18 is smaller than the interior width of the reserved groove 7. The adjustment plate 5 can move horizontally outside the positioning stud 18 on the top of the positioning plate 2. By driving the adjustment plate 5 to move on the top of the positioning plate 2, the positioning plate 5 can move horizontally outside the positioning stud 18 on the top of the positioning plate 2. The movement of the parts in opposite directions can drive the limiting blocks 19 to move in opposite directions within the placement groove 14, thereby adjusting the length and width within the placement groove 14. A hanging nut 17 is provided outside the positioning stud 18 at the top of the adjustment plate 5. After adjusting the spacing of the limiting blocks 19 to a suitable size space for the shoe sole, tightening the hanging nut 17 can stabilize the adjustment plate 5, thereby fixing the limiting blocks 19. This achieves the effect of convenient, quick, and stable adjustment of the shoe sole placement space to suit different sizes of shoe soles that need to be tested for abrasion resistance, further improving the economic efficiency of the device.

[0025] When in use, loosen the eye nut 17 to move the adjustment plate 5 to the top of the positioning plate 2 in opposite directions, which will move the limit block 19 to the placement groove 14 in opposite directions to adjust the length and width of the placement groove 14. After adjusting the spacing of the limit block 19 to a suitable size space for the shoe sole, tighten the eye nut 17 to stabilize the adjustment plate 5 and fix the limit block 19.

[0026] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, a stabilizing component is provided on the top of the inner side of the frame 4. The stabilizing component includes a limiting pressure plate 3, which is located on the top of the placement slot 14. A lifting guide rod 9 is provided at the middle position of the top of the limiting pressure plate 3. A through hole 8 is provided at the middle position of the top of the inner side of the frame 4. The top of the lifting guide rod 9 passes through the interior of the through hole 8. The diameter of the lifting guide rod 9 is smaller than the inner diameter of the through hole 8. A limiting block 13 is provided at the top of the lifting guide rod 9. A compression spring 12 is provided outside the lifting guide rod 9 between the top of the inner side of the frame 4 and the limiting pressure plate 3. The top of the compression spring 12 is fixedly connected to the top of the inner side of the frame 4. Next, the bottom end of the compression spring 12 is fixedly connected to the top end of the limiting pressure plate 3. After the sole is placed inside the placement groove 14, the limiting pressure plate 3 is pushed down by the compression spring 12 and pressed against the top of the positioning plate 2 to achieve the purpose of laying the sole flat and limiting it inside the placement groove 14. The bottom end of the limiting pressure plate 3 is provided with a rubber pad 11. The rubber pad 11 is used to protect the bottom of the limiting pressure plate 3 and the sole. This prevents the sole from being bent by the friction belt 6 during the test and also prevents excessive compression that would cause the sole to fit too tightly with the friction belt 6, thus affecting the accuracy of the test results. It is highly feasible.

[0027] When in use, after the sole is placed inside the placement groove 14, the limiting pressure plate 3 is pushed down by the compression spring 12 and pressed against the top of the positioning plate 2 to keep the sole flat and confined inside the placement groove 14. This prevents the sole from being bent by the friction belt 6 during the test and also prevents excessive compression that would cause the sole to fit too tightly with the friction belt 6. A rubber pad 11 is placed between the bottom of the limiting pressure plate 3 and the sole, and the lifting guide rod 9 is used to support and stabilize the compression spring 12.

[0028] Working principle: When using the testing device, first loosen the eye nut 17, then move the adjusting plate 5 towards or away from the top of the positioning plate 2 according to the required shoe sole size. This will cause the limiting blocks 19 to move towards or away from each other within the placement groove 14, adjusting the length and width of the placement groove 14. After adjusting the spacing of the limiting blocks 19 to a suitable space for the shoe sole size, tighten the eye nut 17 to stabilize the adjusting plate 5, thereby fixing the limiting blocks 19. Then, place the shoe sole in the placement groove 14, and limit the sides of the shoe sole by the limiting blocks 19. Simultaneously, the compression spring 12 pushes the limiting pressure plate 3 down to press against the top of the positioning plate 2, so as to lay the sole flat and limit it inside the placement groove 14. This is to prevent the sole from being bent by the friction belt 6 during the test, and to prevent excessive compression that would cause the sole to fit too tightly with the friction belt 6. A rubber pad 11 is placed between the bottom of the limiting pressure plate 3 and the sole. Then, the servo motor 10 can be started to drive the rotating shaft 15 to drive the rotating drum 16 to rotate forward and backward, which will drive the friction belt 6 to move back and forth to rub the sole, so as to conduct a wear resistance test on the sole.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
