Description

Technical Field

[0001] This utility model relates to the technical field of footwear testing devices, and in particular to a shoe sole bending resistance testing device. Background Technology

[0002] The flexural strength test for shoe soles is an indispensable quality inspection step in the footwear industry. It effectively assesses potential issues such as fatigue, cracking, and damage that may occur during use. Passing the flexural strength test ensures that the quality and durability of shoes meet relevant standards and requirements, providing consumers with a better wearing experience.

[0003] During the experiment, a mechanical device applies cyclic bending forces to the sole of the shoe to simulate the stress changes experienced during walking. Simultaneously, key data such as sole deformation, crack formation, and material fatigue after repeated bending are recorded. However, existing testing equipment has certain shortcomings in securing the sole sample, especially at high flexural speeds, where the clamps are prone to loosening, thus affecting the accuracy of the test results. Utility Model Content

[0004] To reduce the loosening of shoe sole samples during testing, ensure the stability of the shoe sole, and improve the accuracy of test results, this application provides a shoe sole bending resistance testing device.

The bending plate is driven to rotate by the telescopic rod to achieve bending of the shoe sole.

[0007] By employing the aforementioned device, the fixed shaft and bending plate within the workbench can accurately simulate the bending stress experienced by the shoe sole during actual use. The rotation of the bending plate is connected to the workbench, ensuring the stability and repeatability of the bending action. During testing, the shoe sole is securely fixed between the first and second clamping mechanisms, which helps reduce movement or loosening of the shoe sole during the test, thereby improving the accuracy and reliability of the test results.

[0008] Preferably, the first clamping mechanism includes a plurality of first fixing members, and the second clamping mechanism includes a plurality of second fixing members, wherein the first fixing members and the second fixing members correspond one-to-one.

[0009] By employing the aforementioned device, multiple first fixing members are arranged in a one-to-one correspondence with multiple second fixing members, thereby enhancing the stability of the sole during the testing process. This ensures that when the sole is subjected to bending force, the test results will not deviate due to the instability of the fixing members.

[0010] Preferably, the first fixing member includes a pressing rod, a first fixing frame, and a first threaded rod. A mounting frame is provided on the worktable. The pressing rod is connected to the first fixing frame. The first threaded rod passes through the mounting frame and is connected to the top of the first fixing frame. The first threaded rod is threadedly connected to the mounting frame. A first adjusting nut is provided at the end of the first threaded rod away from the first fixing frame.

[0011] By using the above-mentioned device, the position of the pressure bar can be adjusted by rotating the first threaded rod, thereby changing the pressure on the sole to accommodate sole samples with different hardness and thickness, improving the flexibility of sole fixing, and ensuring the stability of the sole during the test.

[0012] Preferably, the second fixing member includes a pressure plate, a second fixing frame, and a second threaded rod. The pressure plate is disposed inside the second fixing frame, and the second threaded rod passes through the second fixing frame and is fixedly connected to the pressure plate. The second threaded rod is threadedly connected to the second fixing frame, and a second adjusting nut is provided at the end of the second threaded rod away from the pressure plate.

[0013] By employing the aforementioned device, the distance between the pressure plate and the second fixed frame can be precisely adjusted by rotating the second threaded rod to accommodate soles of different sizes, ensuring that the fixing components can fit tightly against the soles, improving the accuracy of the test, and reducing test errors caused by unstable fixing.

[0014] Preferably, a rotating tube is sleeved on the outer side of the pressure rod.

[0015] By employing the aforementioned device, the rotating tube on the outside of the pressure bar can protect the pressure bar from direct wear and damage, thereby improving the durability and stability of the entire clamping mechanism.

[0016] Preferably, the bottom of the bending plate is provided with a hinge seat, one end of the telescopic rod is connected to the workbench, and the other end is hinged to the hinge seat.

[0017] By employing the aforementioned device, the hinged connection between the telescopic rod and the hinged seat provides stable mechanical support, and the telescopic rod drives the bending plate to rotate, thereby improving testing efficiency.

[0018] Preferably, a protective cover is provided on the upper end of the worktable, and the protective cover is rotatably connected to the worktable.

[0019] By using the above-mentioned device, the protective cover can reduce accidental contact between operators or other personnel and moving parts inside the workbench during testing, thereby avoiding possible pinching or crushing injuries.

[0020] Preferably, a control panel is provided on one side of the workbench.

[0021] By adopting the above-mentioned devices, the control panel design typically includes user interface elements such as buttons, knobs, and displays, enabling operators to intuitively understand the equipment status and make necessary settings, thus improving the ease of operation.

[0022] This application has the following beneficial effects:

[0023] 1. In this application, the fixed shaft and bending plate within the workbench can accurately simulate the bending stress experienced by the shoe sole during actual use. The rotation of the bending plate is connected to the workbench, ensuring the stability and repeatability of the bending action. During testing, the shoe sole is firmly fixed between the first and second clamping mechanisms, which helps reduce movement or loosening of the shoe sole during the test, thereby improving the accuracy and reliability of the test results.

[0024] 2. In this application, the hinged connection between the telescopic rod and the hinged seat provides stable mechanical support, and the telescopic rod drives the bending plate to rotate, thereby improving testing efficiency. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] A shoe sole bending resistance testing device, such as Figure 1-2 As shown, the system includes a worktable 1, a fixed shaft 2, a bending plate 3, a first clamping mechanism 4, a second clamping mechanism 5, and a telescopic rod 6. The worktable 1 houses the fixed shaft 2 and the bending plate 3, which are arranged side-by-side. The bending plate 3 is rotatably connected to the worktable 1 via a pivot, and the bottom of the bending plate 3 is connected to the telescopic rod 6. The first clamping mechanism 4 is positioned above the fixed shaft 2, and the second clamping mechanism 5 is positioned above the bending plate 3. During testing, the shoe sole sample is fixed between the first clamping mechanism 4 and the second clamping mechanism 5. The telescopic rod 6 drives the bending plate 3 to rotate, thereby bending the shoe sole sample and improving the stability and accuracy of the test.

[0033] like Figure 1-2 As shown, the first clamping mechanism 4 includes multiple first fixing members 41, and the second clamping mechanism 5 includes multiple second fixing members 51. The first fixing members 41 and the second fixing members 51 correspond one-to-one. The shoe sole sample is fixed between the first fixing members 41 and the second fixing members 51, which can realize the simultaneous bending of multiple shoe sole samples and improve the efficiency of testing.

[0034] like Figure 2-3 As shown, the first fixing component 41 includes a pressure rod 411, a first fixing frame 412, and a first threaded rod 413. A mounting frame 11 is fixed on the workbench 1. The first threaded rod 413 passes through the mounting frame 11 and connects to the top of the first fixing frame 412, and is threadedly connected to the mounting frame 11. The pressure rod 411 is connected inside the first fixing frame 412, and a rotating tube 415 is sleeved on the outer side of the pressure rod 411. The rotating tube 415 can rotate freely, protecting the pressure rod 411 from direct wear. A first adjusting nut 414 is provided at the end of the first threaded rod 413 away from the first fixing frame 412. During testing, the shoe sole sample is placed between the pressure rod 411 and the fixing shaft 2. The position of the pressure rod 411 is adjusted by rotating the first adjusting nut 414, ensuring that the pressure rod 411 firmly presses against the shoe sole sample, guaranteeing the stability of the shoe sole during the test.

[0035] like Figure 2 and 4As shown, the second fixing member 51 includes a pressure plate 511, a second fixing frame 512, and a second threaded rod 513. The second threaded rod 513 passes through the second fixing frame 512 and is fixedly connected to the upper surface of the pressure plate 511, and is threadedly connected to the second fixing frame 512. The pressure plate 511 is located inside the second fixing frame 512, and a second adjusting nut 514 is provided at the end of the second threaded rod 513 away from the pressure plate 511. During testing, the shoe sole sample is placed between the pressure plate 511 and the bending plate 3. The position of the pressure plate 511 is adjusted by rotating the second adjusting nut 514, so that the pressure plate 511 firmly presses against the shoe sole sample, ensuring the stability of the shoe sole sample during bending. Furthermore, to further increase the stability of the shoe sole sample during testing, an anti-slip pad is fixed to the bottom of the pressure plate 511 to increase the friction between the pressure plate 511 and the shoe sole, reducing possible slippage of the shoe sole during bending.

[0036] like Figure 2 and 4 As shown, a hinge seat 31 is fixed to the bottom of the bending plate 3, and the bottom of the telescopic rod 6 is connected to the workbench 1, while the other end is hinged to the hinge seat 31. In this application, the hinge seat 31 is a planar hinge seat 31, which has a simple and stable structure. During testing, the telescopic rod 6 drives the bending plate 3 to rotate at a certain angle, thereby achieving the bending of the shoe sole sample.

[0037] like Figure 1 As shown, a protective cover 12 is installed on the workbench 1, and the protective cover 12 is rotatably connected to the workbench 1. The protective cover 12 can reduce accidental contact between the operator or other personnel and the moving parts inside the workbench 1, thereby avoiding possible pinching or crushing injuries. In this application, the protective cover 12 is made of transparent acrylic material, which facilitates observation of the internal operation of the workbench 1.

[0038] like Figure 1 As shown, a control panel 7 is provided on the front side of the workbench 1, which facilitates parameter setting and operation control for users, improving the convenience and efficiency of testing.

[0039] Working principle: By employing a dual clamping mechanism 4 and a second clamping mechanism 5 to fix the shoe sole sample, the stability and reliability of the shoe sole fixation are improved, reducing the problem of the shoe sole sample loosening during high-speed flexion. The pressure rod 411 and the pressure plate 511 can adapt to shoe soles of different thicknesses to ensure the fixing effect. The precise control of the telescopic rod 6 and the flexible movement of the hinge seat 31 enable the bending plate 3 to perform precise bending actions at different angles, improving the accuracy and repeatability of the test.
