In the description of this utility model, "plurality" means more than two, unless otherwise specifically defined.

[0026] like Figures 1-4 As shown, the utility model provides a running shoe bending resistance test structure, which includes a control cabinet, a belt conveyor 10, a bending mechanism 20, a pushing mechanism 30 and a lifting mechanism 40.

[0027] A plurality of running shoes to be tested are placed on the conveyor belt 12 of the belt conveyor 10 , and the plurality of running shoes are arranged in equal intervals.

[0028] The bending mechanism 20 includes a bending block 21 and a first motor 22. The bending block 21 is mounted on a first side of the belt conveyor 10 and is rotatably connected to the frame 11 of the belt conveyor 10. A retaining groove 23 extending laterally inward is defined on the inner side of the bending block 21. The first motor 22 is fixedly mounted on the frame 11 of the belt conveyor 10 and electrically connected to the control cabinet. The first motor 22 controls the rotation of the bending block 21.

[0029] The pushing mechanism 30 is arranged on the second side of the belt conveyor 10 and includes a support plate 31, a guide rod 32, a slider 33, a lead screw 34, and a second motor 35. The support plate 31 is arranged in a transverse direction and is fixedly connected to the frame 11 of the belt conveyor 10. The guide rod 32 is fixedly mounted in a transverse direction on the support plate 31. The slider 33 is arranged on the guide rod 32 and is slidably connected to the guide rod 32. The lead screw 34 passes through the slider 33 in a transverse direction and is threadedly connected to the slider 33. Both ends of the lead screw 34 are rotatably connected to the support plate 31. The second motor 35 is fixedly mounted on the support plate 31 and is electrically connected to the control cabinet. The second motor 35 is used to control the rotation of the lead screw 34.

[0030] The lifting mechanism 40 includes a vertical plate 41, a horizontal plate 42, a lifting plate 43, a movable rod 44, an electric push rod 45 and a pressing block 46. The vertical plate 41 is fixedly mounted on the top of the slider 33. The horizontal plate 42 is arranged above the belt conveyor 10 and is fixedly connected to the vertical plate 41. The lifting plate 43 is arranged below the horizontal plate 42. The movable rod 44 passes through the horizontal plate 42 in the longitudinal direction and is slidably connected to the horizontal plate 42. The movable rod 44 is fixedly connected to the lifting plate 43. The electric push rod 45 is electrically connected to the control cabinet, and the two ends of the electric push rod 45 are fixedly connected to the horizontal plate 42 and the lifting plate 43 respectively. The pressing block 46 is fixedly mounted on the bottom of the lifting plate 43.

[0031] The control cabinet controls the belt conveyor 10 to start, and the running shoes on the conveyor belt 12 of the belt conveyor 10 will gradually move forward, thereby making it convenient to perform a bending resistance test on each running shoe in turn.

[0032] The specific bending resistance test process is as follows:

[0033] First, when the running shoes to be tested move between the pushing mechanism 30 and the bending mechanism 20 , the control cabinet controls the belt conveyor 10 to stop running.

[0034] Then, the control cabinet controls the electric push rod 45 to extend, and under the guidance of the movable rod 44, the lifting plate 43 will drive the pressing block 46 to move downward until the pressing block 46 is inserted into the shoe opening of the running shoe.

[0035] Next, the control cabinet controls the second motor 35 to start, and the second motor 35 drives the lead screw 34 to rotate. Under the action of the guide rod 32, the slider 33 drives the vertical plate 41 and the horizontal plate 42 to move until the toe of the running shoe is pushed into the limit groove 23.

[0036] Finally, the control cabinet controls the electric push rod 45 to continue extending until the pressing block 46 presses the running shoe. At this time, the control cabinet controls the first motor 22 to start, and the bending block 21 will drive the toe of the running shoe to bend, thereby performing a bending resistance test on the running shoe.

[0037] After the flex test is complete, the control cabinet resets all components, including the running shoes. This process eliminates the need for manual contact with the shoes, significantly improving test efficiency. The reset process is the exact opposite of the flex test, so the details are omitted here.

[0038] In one embodiment, an upwardly extending receiving groove 47 is formed at the bottom of the pressing block 46 , and a telescopic assembly 50 is disposed in the receiving groove 47 .

[0039] The telescopic assembly 50 includes a slide bar 51, a moving block 52, a pressing plate 53, an electromagnet 54, an iron block 55, and a spring 56. The slide bar 51 is arranged horizontally, with both ends fixedly connected to the inner wall of the receiving groove 47. The moving block 52 is arranged on the slide bar 51 and is slidably connected to the slide bar 51. The pressing plate 53 is arranged below the pressing plate 46 and is fixedly connected to the moving block 52. The electromagnet 54 and the iron block 55 are arranged opposite each other. The electromagnet 54 is fixedly mounted on the inner wall of the receiving groove 47 and is electrically connected to the control cabinet. The iron block 55 is fixedly mounted on the moving block 52. The spring 56 tends to move the iron block 55 away from the electromagnet 54.

[0040] When the toe of the running shoe is pushed into the limiting groove 23, the control cabinet energizes the electromagnet 54, which attracts the iron block 55 until the two are attracted together. The movable block 52 then drives the pressing plate 53 forward, allowing it to better penetrate the interior of the running shoe. This allows the electric push rod 45 to further extend, thereby achieving a better compression effect on the running shoe and a more stable bending resistance test process.

[0041] After the bending resistance test is completed, the control cabinet can cut off the power to the electromagnet 54, and under the action of the spring 56, the telescopic component 50 will automatically reset.

[0042] In one embodiment, the spring 56 is sleeved on the slide bar 51, and the two ends of the spring 56 are respectively fixedly connected to the inner wall of the receiving groove 47. In this way, the expansion and contraction of the spring 56 will be more stable and will not bend.

[0043] In one embodiment, a guide surface 24 that is inclined downward and extends outward is formed at the bottom of the limiting groove 23 .

[0044] The control cabinet controls the second motor 35 to start, and the second motor 35 drives the screw 34 to rotate. Under the action of the guide rod 32, the slider 33 will drive the vertical plate 41 and the horizontal plate 42 to move, and the toe of the running shoe will first contact the guide surface 24 and then be pushed into the limit groove 23.

[0045] The design of the guide surface 24 enables the toe of the running shoe to automatically tilt up, thereby facilitating the shoe to be pushed into the limiting groove 23 .

[0046] In one embodiment, the belt conveyor 10 further includes a first reinforcing rib 60 , which is fixedly connected to the frame 11 and the support plate 31 of the belt conveyor 10 . The design of the first reinforcing rib 60 can improve the stability of the support plate 31 .

[0047] In one embodiment, the second reinforcing rib 70 is further included, and the second reinforcing rib 70 is fixedly connected to both the vertical plate 41 and the horizontal plate 42. The design of the second reinforcing rib 70 can improve the stability of the horizontal plate 42.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.

[0049] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
