[0021] like Figure 1-Figure 6As shown, the present invention provides a running shoe testing machine, including a control cabinet, a turntable body 10, a ground-like module, a frame, a belt transmission mechanism, a motor, a measurement and control module and a plurality of simulated foot modules 20. The ground-like module includes a lifting platform and a running-type transmission mechanism arranged thereon. The plurality of simulated foot modules 20 are arranged at equal intervals along the circumference of the turntable body 10. The above-mentioned parts are all prior art, and can be used to perform wear tests on running shoes in cooperation with each other. The specific working principle will not be repeated here. In the present invention, the simulated foot module 20 includes an arch body 30, a connecting block 40, a first limit assembly 50, a second limit assembly 60 and an anti-reversal mechanism 70.

[0022] A first guide groove 31 extending inward is formed on the side surface of the arch body 30 , and a first limiting groove 32 communicating with the first guide groove 31 is formed on the inner side surface of the arch body 30 .

[0023] The first end of the connecting block 40 is rotatably connected to the rear end of the arch body 30, and the second end of the connecting block 40 is detachably connected to the turntable body 10. A second guide groove 41 extending inward is formed on the side surface of the connecting block 40, and a second limiting groove 42 communicating with the second guide groove 41 is formed on the inner side surface of the connecting block 40.

[0024] The first limiting assembly 50 includes a moving block 51, a first guide block 52, a first movable block 53, a first limiting block 54, a first connecting rod 55 and a first stopper 56. The moving block 51 is arranged in the first guide groove 31 and is in sliding contact with the inner wall of the first guide groove 31. The first guide block 52 is arranged in the first guide groove 31 and is fixedly connected to the moving block 51 through a connecting column 57. The top of the first guide block 52 is formed with a first inclined surface 58 that is inclined downward and extends outward. The first movable block 53 is arranged in the first limiting groove 32 and is in sliding contact with the inner wall of the first limiting groove 32. The bottom of the first movable block 53 is formed with a second inclined surface 59 that is adapted to the first inclined surface 58. The first limiting block 54 is fixedly mounted on the top of the first movable block 53. The first end of the first connecting rod 55 is hinged to the connecting block 40, and the second end of the first connecting rod 55 is hinged to the moving block 51 after being tilted downward. The first stopper 56 is fixedly mounted on the inner wall of the first guide groove 31 to prevent the moving block 51 from being separated from the first guide groove 31 .

[0025] The second limiting assembly 60 includes a second guide block 61, a second movable block 62, a second limiting block 63 and a second connecting rod 64. The second guide block 61 is arranged in the second guide groove 41 and is in sliding contact with the inner wall of the second guide groove 41. The outer side surface of the second guide block 61 is formed with a third inclined surface 65 that is inclined upward and extends outward. The second movable block 62 is arranged in the second limiting groove 42 and is in sliding contact with the inner wall of the second limiting groove 42. The inner end surface of the second movable block 62 is formed with a fourth inclined surface 66 that is adapted to the third inclined surface 65. The second limiting block 63 is fixedly mounted on the outer end surface of the second movable block 62. The first end of the second connecting rod 64 is hinged to the arch body 30, and the second end of the second connecting rod 64 is hinged to the second guide block 61 after tilting upward. The second stopper is fixedly mounted on the inner wall of the second guide groove 41 to prevent the second guide block 61 from escaping from the second guide groove 41.

[0026] The anti-reversal mechanism 70 is used to prevent the second end of the connecting block 40 and the front end of the arch body 30 from moving away from each other.

[0027] In the initial state, the moving block 51 contacts the first stopper 56, and the second guide block 61 contacts the second stopper. At this time, the angle between the arch body 30 and the connecting block 40 is an obtuse angle.

[0028] The specific process of wearing running shoes on the simulation foot module 20 is as follows: First, the staff places the running shoes on the running transmission mechanism, and the running shoes are located directly below the corresponding artificial foot module 20.

[0029] Then, the staff controls the lifting platform through the control cabinet to start, and the running transmission mechanism and the running shoes will move upward synchronously, and the arch body 30 and the connecting block 40 will enter the running shoes one after another. Since the angle between the arch body 30 and the connecting block 40 is an obtuse angle, and the running shoes play a limiting and guiding role, during the entry process, the angle between the arch body 30 and the connecting block 40 gradually decreases until the angle between the two is 90°, and the anti-reversal mechanism 70 can prevent the angle between the arch body 30 and the connecting block 40 from resetting. When the angle between the arch body 30 and the connecting block 40 gradually decreases, the first connecting rod 55 pushes the moving block 51 and the first guide block 52 inwards, and under the guidance of the first inclined surface 58 and the second inclined surface 59, the first limit block 54 extends upwards and presses the shoe body of the running shoe; similarly, the second connecting rod 64 pushes the second guide block 61 inwards, and under the guidance of the third inclined surface 65 and the fourth inclined surface 66, the second limit block 63 extends rightwards and presses the shoe opening of the running shoe. In this way, a stable support can be formed for the inside of the running shoe, so that the running shoe can be stably tested for wear in the future.

[0030] In one embodiment, a rotation shaft 34 is fixedly mounted on the rear end of the arch body 30 , and the rotation shaft 34 is rotatably connected to the first end of the connection block 40 .

[0031] The anti-reversal mechanism 70 includes a ratchet 71 and ratchet teeth 72. The ratchet 71 is fixedly mounted on the rotating shaft 34, and the ratchet teeth 72 are disposed on the connecting block 40 and meshed with the ratchet 71.

[0032] When the angle between the arch body 30 and the connecting block 40 gradually decreases, the arch body 30 will drive the rotating shaft 34 and the ratchet 71 to rotate, and the ratchet 71 will slip on the ratchet teeth 72 at this time.

[0033] The cooperation between the ratchet wheel 71 and the ratchet teeth 72 can achieve an anti-reversal effect, so that when performing a wear test, the artificial foot module 20 can provide stable support for the interior of the running shoe, and the structure is simple and easy to manufacture.

[0034] In one embodiment, a sliding groove is formed on the inner wall of the connecting block 40 .

[0035] The anti-reversal mechanism 70 also includes a slider 73, a connecting shaft, a first torsion spring 74, a first electromagnet 75 and a second electromagnet 76. The slider 73 is in sliding contact with the inner wall of the slide groove. The first end of the connecting shaft is rotatably connected to the slider 73, and the second end of the connecting shaft is fixedly connected to the ratchet 72. The first torsion spring 74 is sleeved on the connecting shaft, and the two ends of the first torsion spring 74 are respectively fixedly connected to the slider 73 and the ratchet 72. The first torsion spring 74 makes the tip of the ratchet 72 have a tendency to approach the ratchet 71. The first electromagnet 75 and the second electromagnet 76 are arranged opposite to each other and are both electrically connected to the control cabinet. The first electromagnet 75 is fixedly mounted on the slider 73, and the second electromagnet 76 is fixedly mounted on the inner wall of the connecting block 40.

[0036] In the initial state, the control cabinet energizes the first electromagnet 75 and the second electromagnet 76, and the two repel each other, and the ratchet 72 and the ratchet wheel 71 are in meshing state.

[0037] When the wear test is completed, the control cabinet changes the current direction of the first electromagnet 75. At this time, the first electromagnet 75 and the second electromagnet 76 attract each other, and the slider 73 drives the ratchet 72 away from the ratchet 71. The arch body 30 and the connecting block 40 can rotate freely, and the two are in a free state, so that the staff can easily take the simulated foot module 20 out of the running shoes.

[0038] In one embodiment, a second torsion spring is sleeved on the rotating shaft 34 , and two ends of the second torsion spring are fixedly connected to the connecting block 40 and the arch body 30 respectively.

[0039] In the initial state, due to the action of the second torsion spring, the angle between the arch body 30 and the connecting block 40 remains at an obtuse angle.

[0040] When the wear test is completed, the slider 73 drives the ratchet 72 away from the ratchet 71. Due to the action of the second torsion spring, the angle between the arch body 30 and the connecting block 40 will gradually increase, and the first limit block 54 will move downward and break contact with the shoe body of the running shoe; the second limit block 63 will also move to the left and break contact with the shoe opening of the running shoe, thereby further facilitating the staff to take the simulated foot module 20 out of the running shoe.

[0041] In one embodiment, a sealing ring is fixedly installed on the outer circumferential surface of the moving block 51 , the moving block 51 is sealedly connected to the inner wall of the first guide groove 31 , and a sealing cavity 33 is formed between the moving block 51 and the first guide groove 31 .

[0042] An airbag 80 is disposed between the first limiting block 54 and the second limiting block 63 . Two ends of the airbag 80 are fixedly connected to the first limiting block 54 and the second limiting block 63 , respectively. The airbag 80 is connected to the sealing cavity 33 via a hose 81 .

[0043] As the angle between the arch body 30 and the connecting block 40 gradually decreases, the first connecting rod 55 pushes the moving block 51 and the first guide block 52 inward. At this time, the air in the sealing cavity 33 enters the airbag 80, and the airbag 80 expands, thereby forming support for the curved part of the shoe body, providing better stable support for the running shoes.

[0044] In one embodiment, a first curved surface is formed on the top of the first limiting block 54, and the first curved surface better fits the shape of the shoe body.

[0045] In one embodiment, a second arc-shaped surface is formed on the outer side surface of the second limiting block 63, and the second arc-shaped surface better fits the shape of the shoe opening.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention.
