[0001] The present invention relates to the field of leather shoe testing, and particularly to a device for detecting the bending and extrusion forces on leather shoes. Background Art

[0002] Leather shoes generally refer to shoes made of leather, which can provide certain protection for the feet and prevent the feet from being invaded by external objects. When wearing leather shoes, the connecting section between the instep and the heel is often subjected to strong bending and extrusion. Usually, the glue separation and cracking of the shoes start from the contact position between the upper and the sole at this connecting section. In order to know the performance of leather shoes that may withstand bending and extrusion under actual use conditions, some manufacturers will use a bending and extrusion force detection device to detect leather shoes during production.

[0003] However, in the existing technology, the bending and extrusion force detection device can only detect the durability and quality of the leather shoes themselves. However, when people wear leather shoes, the bent part of the leather shoes will exert pressure on the instep, and some bending and extrusion force detection devices cannot test the pressure exerted on the instep when the leather shoes are bent, and their practicability is significantly insufficient. In addition, when some bending and extrusion force detection devices test multiple groups of leather shoes, they need to be fixed one by one, which is too complicated. Therefore, a device for detecting the bending and extrusion forces on leather shoes is specifically proposed to solve these problems. Summary of the Invention

[0004] To make up for the above deficiencies, the present invention provides a device for detecting the bending and extrusion forces on leather shoes, aiming to improve the problem that some bending and extrusion force detection devices in the existing technology cannot test the pressure exerted on the instep at the bent part of the leather shoes, and their practicability is too low.

Detailed implementation

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figure 1 - Figure 3 As shown in the figure, an embodiment provided by the present invention: A leather shoe bending and extrusion force detection device includes a detection device 1. The detection device 1 is a prior art and can perform bending fatigue tests on leather shoes. The leather shoes are fixed on the bending plate 2, and then the bending plate 2 is swung by starting the driving mechanism on the detection device 1 to repeatedly bend the leather shoes. At this time, the detection device 1 can judge the durability of the leather shoes by recording the number of bends. There is a bending plate 2 on the upper surface of the detection device 1, a support rod 3 on the upper surface of the bending plate 2, and a connecting plate 4 is slidably connected to the outer wall of the support rod 3. The connecting plate 4 is cooperatively connected with multiple groups of support rods 3, detection components 5, and fixing components 7 to ensure that multiple groups of leather shoes can be fixed, improving the practicability. There is a detection component 5 on the lower surface of the right end of the connecting plate 4, a driving component 6 on the rear surface of the top of the support rod 3, and a fixing component 7 at the bottom of the detection component 5. The detection component 5 includes a sleeve 51, and the sleeve 51 is fixedly connected to the lower surface of the right end of the connecting plate 4. There are multiple groups of grooves on the front surface of the sleeve 51. Setting multiple groups of grooves can ensure that the detection component 5 can test leather shoes of different sizes, improving the practicability. A slide block 52 is slidably connected to the outer wall of the sleeve 51, and a rectangular shell 55 is fixedly connected to the right surface of the slide block 52.

[0024] Refer to Figure 1 - Figure 2, the driving component 6 includes a connecting block 62. The connecting block 62 is fixedly connected to the rear surface of the top end of the support rod 3. A threaded rod 61 is rotatably connected through the upper surface of the connecting block 62. The threaded rod 61 is a prior art, which is a rod-shaped structure with threads on its outer wall. When the threaded rod 61 is rotated, the connecting plate 4 connected to its outer wall will linearly move along its axis. At the same time, it has a certain self-locking property to ensure the stability of the structure. The threaded rod 61 is threadedly connected through the upper surface of the connecting plate 4.

[0025] Refer to Figure 2 - Figure 4 , the fixing component 7 includes a fixing rod 71. The fixing rod 71 is slidably connected to the inner wall of the sleeve 51. A second spring 72 is fixedly connected to the upper surface of the fixing rod 71. The second spring 72 has a certain elasticity. Through its own elasticity, the fixing rod 71 can adapt to leather shoes of different thicknesses, ensuring that the device can test leather shoes of different thicknesses at the same time. The top end of the second spring 72 is fixedly connected to the inner wall of the sleeve 51. The bottom end of the fixing rod 71 is made of rubber material, and the rubber material has a certain elasticity, ensuring the stability of fixing the leather shoes and avoiding pinching the leather shoes, thus improving the practicability.

[0026] Refer to Figure 2 - Figure 3 , a screw rod 59 is slidably connected to the left end inner wall of the rectangular shell 55. The screw rod 59 is a prior art, and its principle is similar to that of the threaded rod 61, so it will not be elaborated here. A circular plate is provided at its left end. The diameter of the circular plate is greater than the height of the rectangular shell 55 from top to bottom but less than the length of the rectangular shell 55 from front to back, ensuring that workers can smoothly control its rotation and improving the practicability. A rectangular block 56 is threadedly connected to the outer wall of the screw rod 59. The rectangular block 56 is slidably connected to the inner wall of the rectangular shell 55. An elastic sheet 57 is fixedly connected to the right surface of the rectangular block 56. The elastic sheet 57 has a certain elasticity. Through its own elasticity, it can ensure that the flexible induction pad 58 fits the inner surface of the leather shoe. The upper surface of the elastic sheet 57 is fixedly connected to the flexible induction pad 58. The flexible induction pad 58 is a prior art. The flexible induction pad 58 is a pad that can sense information such as pressure and position. It is usually made of flexible materials and can be bent and folded to adapt to different shapes and surfaces. Under the action of the elastic sheet 57, it can be made to fit the inner surface of the leather shoe.

[0027] Refer to Figure 2 - Figure 3 , a limiting rod 53 is slidably connected through the front surface of the slider 52. The rear end of the limiting rod 53 contacts the inner wall of the groove. A first spring 54 is sleeved on the outer wall of the limiting rod 53. The first spring 54 always pulls the limiting rod 53 backward through its own elasticity to ensure the stability of the limit. One end of the first spring 54 is fixedly connected to the rear surface of the limiting rod 53, and the other end of the first spring 54 is fixedly connected to the front surface of the slider 52.

[0028] Working principle: When testing leather shoes, multiple groups of leather shoes can be placed on the upper surface of the bending plate 2, and the heels of the leather shoes can be made to contact the right surface of the support rod 3. At this time, the threaded rod 61 is rotated, and the connecting plate 4 will move linearly with its rotation, and the sleeve 51 will also move until the fixed rod 71 contacts the inside of the leather shoe. At this time, the threaded rod 61 is continued to be rotated, and the fixed rod 71 will slide on the inner wall of the sleeve 51 and squeeze the spring 2 72. The spring 2 72 will make the clamping of the fixed rod 71 more stable through its own elastic reaction force, and then the screw rod 59 can be rotated, and the rectangular block 56 will move accordingly, and the rectangular block 56 will mobilize the elastic sheet 57 and the flexible sensing pad 58 to move together. Move until the flexible sensing pad 58 overlaps with the bending point of the leather shoe. At this time, pull the limit rod 53 to make it disengage from the inner wall of the groove. At the same time, the limit rod 53 will stretch the spring 54, so that the height of the slider 52 can be adjusted. The slider 52 will drive the rectangular shell 55 to move, and the rectangular block 56, the elastic sheet 57, and the flexible sensing pad 58 will also move accordingly. At the same time, the flexible sensing pad 58 and the elastic sheet 57 will bend along the curvature inside the leather shoe to ensure the fit. Then, the toe of the leather shoe is fixed by another set of clamps, and a bending test can be performed. During the bending process, the flexible sensing pad 58 will test the pressure generated by the bending part of the leather shoe on the instep, thereby improving practicality.

[0029] When disassembling, move the slider 52 so that the flexible sensing pad 58 does not contact the leather shoe, and then rotate the screw 59 to retract the flexible sensing pad 58. The specific operation is the same as above, except that the movement mode of some structures is opposite to that of above.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
