DETAILED DESCRIPTION

[0028] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0029] In the present invention, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] See also Figure 1-3 The knitted socks wear resistance test device shown includes a test bench 1 and a movable plate 4 installed on the test bench 1, the movable plate 4 is configured to be able to move vertically, and a lower pedal 12 is installed on the movable plate 4. A fixed frame 8 is provided on the test bench 1 at the periphery of the movable plate 4, a first cylinder 10 is installed on the top of the fixed frame 8, a foot mold 9 is installed on the bottom of the first cylinder 10, and the lower pedal 12 is configured to be able to squeeze on the bottom surface of the foot mold 9.

[0031] Through the implementation of the above technical solution, the knitted socks wear durability testing device can simulate the scene of walking to test the wear durability of knitted socks. For example, the lower pedal 12 impacts the foot mold 9 to simulate the state when the foot touches the ground. Through multiple uninterrupted simulations, the wear durability of the knitted socks is finally judged according to the damage of the knitted socks.

[0032] In this embodiment, the test bench 1 is mounted with a second cylinder 5 connected to the movable plate 4. The test bench 1 is also provided with a plurality of guide rods 14 that slide through the movable plate 4, with limit plates 15 positioned at the tops of the guide rods 14. This arrangement provides a means of driving the movable plate 4 up and down, and the guide rods 14 enhance the stability of the structure.

[0033] In this embodiment, hinged seats 16 are provided on both sides of the movable plate 4, and both sides of the lower pedal 12 are rotatably connected to the hinged seats 16. A fourth cylinder 13 is hingedly connected to the front end of the movable plate 4, and the upper end of the fourth cylinder 13 is hingedly connected to the front end of the lower pedal 12. The fourth cylinder 13 can be used to flip the front end of the lower pedal 12, simulating the state of the foot when walking with the heel raised.

[0034] In this embodiment, in order to prevent the fourth cylinder 13 from being blocked during rotation, a second through hole 3 for avoiding the fourth cylinder 13 is provided on the test bench 1 .

[0035] In this embodiment, the rear end of the lower pedal 12 is provided with a notch 6, and a heel pedal 7 is hinged in the notch 6. The independent heel pedal 7 can simulate the situation of inner height increase and test the wear resistance of knitted socks when the soles have inner height increase.

[0036] In this embodiment, the bottom surface of the heel pedal 7 is provided with a groove 19, and the bottom surface of the notch 6 is provided with a first through-hole 20. A third cylinder 11 is hingedly connected to the first through-hole 20, and the upper end of the third cylinder 11 is hingedly connected to the groove 19. The third cylinder 11 can push the heel pedal 7 to flip at different angles, thereby simulating the wear resistance of knitted socks with different heights.

[0037] In this embodiment, the upper surface of the heel pedal 7 is provided with a cambered convex portion. By such arrangement, since walking usually involves the heel first touching the ground, the foot mold 9 can contact the heel pedal 7 first.

[0038] In this embodiment, a vertical plate 2 is provided at the front end of the test bench 1, and an infrared counter 17 is mounted on the vertical plate 2. With this arrangement, the infrared counter 17 emits a counting beam to the movable plate 4, and counts once when the movable plate 4 moves up and is out of the illumination of the counting beam.

[0039] In this embodiment, in order to further provide a foot mold 9, the foot mold 9 has a built-in muscle and bone structure 18, and the front toe can be elastically turned. The outside of the foot mold 9 is wrapped with silicone.

[0040] The present invention also provides a knitted socks wear durability test method, which uses the knitted socks wear durability test device and comprises:

[0041] S1, place the knitted socks to be tested on the foot mold 9, start the movable plate 4 to move upward and make the lower pedal 12 hit the foot mold 9, simulating a foot pedal operation;

[0042] S2, after the lower pedal 12 hits the foot mold 9 once, the front end of the lower pedal 12 presses the foot mold 9 upward to rotate it upward, simulating the heel lifting and toe force operation;

[0043] S3, the lower pedal 12 rotates back to its original position, and the lower pedal 12 moves downward, completing one pedaling simulation;

[0044] Repeat steps S1-S3 to perform a set number of wear resistance tests on the knitted socks.

[0045] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0047] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
