Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and in particular relates to a shoe stability testing machine based on dynamic impact and displacement measurement. Background Technology

[0002] Shoe stability testing is primarily used to assess the anti-slip performance of footwear products. By simulating friction, it evaluates the stability of the sole to ensure safety during wear. Existing pendulum friction testers for shoe stability cannot simulate slippage caused by sudden external forces (stepping, slipping, or impacts) during wear. Furthermore, the testing method relies on manual operation, resulting in uneven loading, poor repeatability, and a lack of precise control over impact energy and quantitative recording of response displacement. Consequently, the test results cannot objectively reflect safety in actual use. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the purpose of this utility model is to provide a shoe stability testing machine that simulates sudden external force impact and quantifies the displacement to test the anti-slip stability of shoes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A shoe stability testing machine includes a frame, an impact mechanism at the top of the frame, a pad on the bottom plate of the frame, a sample mechanism above the pad, a shoe last on the sample mechanism, the shoe last being positioned above the pad, and the sample mechanism being positioned below the impact mechanism; a protective net is provided on the side of the frame away from the pad, and the protective net surrounds the sample mechanism and the impact mechanism. The impact mechanism includes a rotating shaft mounted on the top of the frame, a pendulum extending forward through the middle of the rotating shaft, and an impact head at the end of the pendulum away from the rotating shaft. The pendulum is equipped with a positioning ring, and a first positioning seat is provided on one side of the positioning ring. The first positioning seat is set on the frame. The ring surface of the positioning ring near the first positioning seat is provided with an L-shaped notch for a latching hole. The first positioning seat is provided with a release head that matches the latching hole. The latching hole is hooked onto the release head. A second positioning seat is provided above the first positioning seat. The first positioning seat and the second positioning seat are spaced apart in the longitudinal direction. The second positioning seat is mounted on the frame and has the same structure as the first positioning seat.

[0005] Furthermore, in some embodiments, the sample mechanism includes a load seat, a shoe last is provided below the load seat, a load weight is provided above the load seat, guide rail assemblies are provided on the outer sides of both sides of the load seat, and the guide rails are mounted on the base plate of the frame; a slider seat is provided above the load seat, the slider seats are spaced apart above the load seat, and slider assemblies matching the guide rails are provided on both sides of the bottom surface of the slider seat, the slider is locked on the guide rails, and a positioner is provided on the outer side of the slider.

[0006] Furthermore, in some embodiments, a guide seat assembly is fixedly provided on the top of the slider seat, the guide seat assembly is located above the load seat, a cylinder fixing seat is provided between the tops of the guide seat assembly, and the two ends of the cylinder fixing seat are respectively fixedly connected to the tops of the guide seats on both sides; a through guide rod is provided in the guide seat, and an upper crossbar is provided at the top of the guide rod away from the guide seat, and the two ends of the upper crossbar are respectively fixedly connected to the tops of the guide rods on both sides.

[0007] Furthermore, in some embodiments, the bottom end of the guide rod away from the upper crossbar passes through the cylinder fixing seat, guide seat, and slider seat in sequence and is then placed on the load seat. The bottom end of the guide rod is fixedly connected to the load seat, and the guide rod is slidably connected to the cylinder fixing seat, guide seat, and slider seat, that is, the guide rod slidably passes through the cylinder fixing seat, guide seat, and slider seat. A lifting cylinder is provided below the cylinder fixing seat, and the cylinder rod of the lifting cylinder is set towards the upper crossbar, with the top end of the cylinder rod abutting against the bottom surface of the upper crossbar.

[0008] Furthermore, in some embodiments, an electromagnetic clutch is provided on one side of the rotating shaft, the electromagnetic clutch is mounted on the frame, and a release cylinder for driving the extension and retraction of the release head is provided on the side of the first positioning seat away from the positioning ring, the piston rod of the release cylinder being connected to the release head.

[0009] This application simulates a sudden external force impact by placing the test shoe on a friction surface of a mat and applying a load simulating human body weight. A pendulum device then impacts the shoe with a preset energy. The displacement distance of the shoe after the impact is measured; a larger displacement indicates poorer stability (easier to slip and fall), while a smaller displacement indicates better stability (less likely to move) and less chance of falling. This application uses dynamic impact and displacement measurement to evaluate the anti-slip stability of footwear, simulating real sudden impacts. The test is highly automated, the data is quantifiable, and the accuracy of the test is improved. Attached Figure Description

The two ends of the upper crossbar 37 are fixedly connected to the tops of the guide rod 42 on both sides.

[0017] The bottom end of the guide rod 42, away from the upper crossbar 37, passes through the cylinder fixing seat 43, guide seat 49, and slider seat 48 in sequence and is then placed on the load seat 41. The bottom end of the guide rod 42 is fixedly connected to the load seat 41, and the guide rod 42 is slidably connected to the cylinder fixing seat 43, guide seat 49, and slider seat 48, that is, the guide rod 42 is slidably inserted in the cylinder fixing seat 43, guide seat 49, and slider seat 48.

The buckle 31 of the positioning ring 24 is hooked onto the release head 32. The release head 32 retracts and unlocks. The impact head 21 swings towards the shoe last 12. The impact head 21 hits the sample shoe on the shoe last 12, causing the sample shoe on the shoe last 12 to move on the pad 13. The displacement distance is recorded by the positioner 36 on the slider 45, and the friction coefficient of the sole is calculated to obtain the anti-slip stability performance of the shoe.
