Description

Technical Field

[0001] This invention relates to the field of shoe sole friction technology, specifically to a testing device for shoe sole friction testing. Background Technology

[0002] Common characteristics of shoe sole materials should include wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy adaptation to foot shape, resistance to deformation after shaping, heat retention, and easy absorption of moisture. At the same time, they should work in conjunction with the midsole to provide braking effect when changing feet to prevent slipping and to facilitate stopping. After the soles are manufactured, they need to undergo some tests before they can be used. One of these tests is the friction test of the sole.

[0003] Most shoe sole friction testing devices simulate the friction force of shoe soles under different environments. However, the friction force values ​​of the same shoe sole will be different for people of different weights, which will lead to errors in friction force testing.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a testing device for testing the friction of shoe soles, which has the following beneficial effects:

[0018] 1. By using the first and second housings together, the electric telescopic rod is activated, which pushes the fine sand. The fine sand enters the second housing through the second and first feed pipes, increasing the weight of the second housing and thus increasing the pressure on the sole of the shoe. This facilitates the simulation of friction between people of different weights and the sole of the shoe, improving the accuracy of sole friction detection.

[0019] 2. With the inclined plate, after the friction test of the shoe sole is completed, the valve is opened. At this time, the fine sand that has entered the second housing will return to the first housing through the first and second discharge pipes under the action of the inclined plate, which facilitates the recycling of fine sand and improves the ease of use of the shoe sole friction test device.

[0020] 3. By setting the sealing ring, the sealing ring can seal the gap between the push plate and the first housing, thereby preventing the fine sand from leaking when the push plate pushes the fine sand to move, and improving the sealing effect of the fine sand.

[0021] 4. By using the combination of the locking block and the fixing block, after the friction test of the sole is completed, the second housing will be reset under the pulling force of the force gauge, so that the locking block enters the semi-circular groove on the fixing block, thereby positioning the second housing and ensuring that the first feed pipe and the first discharge pipe are connected to the second feed pipe and the second discharge pipe, thus improving the effectiveness of the sole friction test device.

[0022] 5. By using anti-slip texture and plastic sheet together, the motor drives the pulley to rotate, and the pulley drives the transmission belt to rotate, so that the sole of the shoe can come into contact with the anti-slip texture and plastic sheet, thereby changing the friction between the sole and the contact surface during shoe sole testing and improving the diversity of shoe sole friction testing devices.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figures 1-6A testing device for shoe sole friction includes a carrier plate 7. Two connecting plates 5 are welded to the upper surface of the carrier plate 7. A pulley 3 is rotatably connected to one side of the connecting plate 5. A transmission belt 6 is wound between the two pulleys 3. A motor is bolted to one side of one of the connecting plates 5, and one end of the motor output shaft passes through the connecting plate 5 and is fixed to the pulley 3. Multiple feet 8 are welded to the upper surface of the carrier plate 7. A first housing 10 is welded to the top of the feet 8. An electric telescopic rod 9 is bolted to the upper surface of the carrier plate 7. One end of the electric telescopic rod 9 passes through the first housing 10 and is bolted to a push plate. 21. A second discharge pipe 22 and a second inlet pipe 24 are welded to one side of the first housing 10, and the second discharge pipe 22 and the second inlet pipe 24 are connected to the first housing 10. A sealing gasket 23 is glued to one end of the second discharge pipe 22 and the second inlet pipe 24. A support plate 2 is welded to the upper surface of the carrier plate 7, and the pulley 3 is rotatably connected to the support plate 2. Two sliding grooves 33 are opened on one side of the support plate 2, and a sliding plate 35 is slidably connected in the sliding grooves 33. Two sliding openings 34 are opened on one side of the sliding plate 35, and a slide frame 16 is slidably connected in the sliding openings 34. The upper surface of the slide frame 16 is fixed by bolts. A second housing 14 has a first feed pipe 17 and a first discharge pipe 19 welded to its top and bottom, respectively. The first feed pipe 17 and the first discharge pipe 19 are connected to the second housing 14 and are in contact with the sealing gasket 23. A connecting rod 31 is welded to one side of the slide 16. A fixing plate 11 is welded to the upper surface of the carrier plate 7. A force gauge 32 is bolted to one side of the fixing plate 11 and is in contact with the connecting rod 31. A slot 36 is provided at the bottom of the slide 16. Fine sand is provided inside the first housing 10. Pulling the first... The second housing 14 moves upward, causing the slide 16 to move upward along the slide opening 34. The slide 16 then causes the connecting rod 31 to move upward, placing the shoe sole into the slot 36 at the bottom of the slide 16. The second housing 14 is then lowered, at which point the shoe sole contacts the conveyor belt 6. The electric telescopic rod 9 is then activated, extending to push the push plate 21. The push plate 21 pushes the fine sand in the first housing 10 upward. The fine sand enters the second housing 14 through the second feed pipe 24 and the first feed pipe 17, thereby increasing the weight of the second housing 14 to simulate people of different weights.

[0032] In particular, in this invention, the upper surface of the conveyor belt 6 is provided with anti-slip texture 1, and a plastic cloth 13 is adhered to the outer side of the conveyor belt 6. The motor drives the pulley 3 to rotate, and the pulley 3 drives the conveyor belt 6 to rotate, so that the sole of the shoe can come into contact with the anti-slip texture 1 and the plastic cloth 13 to change the friction force between the sole and the contact surface during the shoe sole test. One side of the connecting plate 5 is fixed with a support frame 4 by bolts, and the support frame 4 is fixed with the motor. One side of the fixing plate 11 is provided with a clearance groove 12, and the conveyor belt 6 passes through the clearance groove 12. The bottom inner wall of the second housing 14 is fixed with an inclined plate 30 by bolts, and the top outer wall of the second housing 14 is fixed with a handle 15 by bolts. A valve 18 is sleeved on the outer side of the first discharge pipe 19. After the shoe sole friction test is completed, the valve 18 is opened. At this time, the fine sand that has entered the second housing 14 will return to the first housing 10 through the first discharge pipe 19 and the second discharge pipe 22 under the action of the inclined plate 30. To facilitate the recycling of fine sand, a sealing ring 20 is fitted on the outer side of the push plate 21, and the sealing ring 20 is slidably connected to the first housing 10. A slide cylinder 26 is fixed to one side of the second housing 14 by bolts. A guide rod 25 is slidably connected inside the slide cylinder 26. A locking block 28 is welded to one end of the guide rod 25. A spring 27 is fitted on the outer circumference of the guide rod 25, and the two ends of the spring 27 are fixed to the slide cylinder 26 and the locking block 28, respectively. A fixing block 29 is fixed to one side of the outer wall of the first housing 10 by bolts. A semi-circular groove is opened on one side of the fixing block 29, and the locking block 28 contacts the semi-circular groove. After the friction force of the shoe sole is tested, the second housing 14 will be reset under the pulling force of the force gauge 32, so that the locking block 28 enters the semi-circular groove on the fixing block 29, thereby positioning the second housing 14 and ensuring that the first feed pipe 17 and the first discharge pipe 19 are connected to the second feed pipe 24 and the second discharge pipe 22.

[0033] The working principle of this embodiment is as follows: In use, by pulling the handle 15, the second housing 14 is moved upward. The second housing 14 drives the slide 16 to move upward along the slide opening 34. The slide 16 drives the connecting rod 31 to move upward, placing the shoe sole into the slot 36 at the bottom of the slide 16. Then, the second housing 14 is lowered, at which point the shoe sole contacts the conveyor belt 6. Then, the electric telescopic rod 9 is activated. The electric telescopic rod 9 extends and pushes the push plate 21 to move. The push plate 21 pushes the fine sand in the first housing 10 upward. The fine sand will pass through the second feed pipe 24 and the... A feed pipe 17 enters the second housing 14, thereby increasing the weight of the second housing 14 to simulate people of different weights. Once the appropriate weight is reached, the electric telescopic rod 9 is closed, and the motor is started. The motor drives the pulley 3 to rotate, and the pulley 3 drives the transmission belt 6 to rotate. The transmission belt 6, through the friction between itself and the sole of the shoe, drives the slide 16 to move along the slide groove 33 via the slide plate 35, pulling the force gauge 32 to detect the friction of the sole. At the same time, the slide 16 drives the second housing 14 to move, and the second housing 14 drives the first feed pipe... 17. The first discharge pipe 19 and the slide cylinder 26 move, causing the first feed pipe 17 and the first discharge pipe 19 to disengage from the sealing gasket 23. At the same time, the slide cylinder 26 drives the guide rod 25 to move, and the guide rod 25 drives the locking block 28 to move, causing the locking block 28 to disengage from the semi-circular groove on the fixed block 29. As the locking block 28 moves, it is pushed by the fixed block 29 to move through the guide rod 25 and compress the spring 27. When the locking block 28 disengages from the fixed block 29, the locking block 28 will reset under the force of the spring 27. As the conveyor belt 6 rotates, it will cause the anti-slip texture 1 and plastic cloth 13 to come into contact with the sole of the shoe, thereby changing the friction between the sole and the contact surface in different scenarios. After the test is completed, the motor is turned off. At this time, the slide 16 will be reset under the action of the force gauge 32, so that the device returns to its original state. Then the electric telescopic rod 9 is started to retract. When the push plate 21 moves to its original position, the valve 18 is opened. At this time, the fine sand in the second housing 14 will return to the first housing 10 through the first discharge pipe 19 and the second discharge pipe 22.
