Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a bending resistance testing device for running shoe soles. Background Technology

[0002] Utility model patent CN214472436U discloses a shoe sole bending test mechanism, including a load-bearing component, a fixing component, and a bending component. The load-bearing component includes a base, a support rod, and a load-bearing rod. The fixing component includes a first motor, a lead screw, a lead screw seat, a connecting block, an electric push rod, a pressure plate, and a sliding plate. The bending component includes a second motor, a transmission shaft, and several cams. In this design, the shoe sole to be tested is placed on the upper part of the base, with the front half of the sole in contact with the cams. The first motor is used to adjust the position of the sliding plate, thus fixing the shoe sole. Different sizes of shoe soles can be tested without changing the pressure plate, and multiple samples can be tested simultaneously. Furthermore, the cams are composed of multiple cam plates, allowing for adjustment of their orientation and simulation of various testing conditions.

[0003] However, the device has certain shortcomings in use. It is not convenient to support soles of different lengths. At the same time, the soles lack limiting, and they are prone to positional movement during bending. Utility Model Content

[0004] The purpose of this invention is to provide a bending resistance testing device for running shoe soles, which solves the problems that the device is not convenient for supporting soles of different lengths, and that the soles lack limiting features and are prone to positional movement during bending.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending resistance testing device for running shoe soles, comprising a frame, a cylinder fixedly installed at the upper middle part of the frame, the cylinder rod of the cylinder passing through the frame and slidably connected to the frame, a pressure strip fixedly connected to the end of the cylinder rod, a bracket slidably connected to the upper end of the frame, a support mechanism provided on the frame, a support roller provided on the bracket, and a limit mechanism provided on the bracket.

[0006] Preferably, the support mechanism includes a sliding plate, which is fixedly connected to a bracket and slidably connected to a frame. A bidirectional screw is movably connected internally to the sliding plate, and a pressure plate is threadedly connected to the outer side of the bidirectional screw. The pressure plate is slidably connected to the frame, and a spring is provided on the outer side of the bidirectional screw. By rotating the bidirectional screw and the pressure plate to perform threaded movement, the spring elastically compresses the sliding plate, causing the sliding plate to change the distance between the two brackets, thus supporting soles of different lengths.

[0007] Preferably, a limiting plate is fixedly connected to the lower end of the frame, and the limiting plate is rotatably connected to the bidirectional screw. The limiting plate limits the movement of the bidirectional screw.

[0008] Preferably, one end of the spring is fixedly connected to the pressure plate, and the other end of the spring is fixedly connected to the slide plate. The spring provides elastic support to the slide plate.

[0009] Preferably, the limiting mechanism includes a screw, which is mounted inside the bracket via a bearing. A screw cylinder is threadedly connected to the outside of the screw, and a slide cylinder is slidably connected to the outside of the screw cylinder. A slide block is fixedly connected to the lower end of the slide cylinder, and the slide block and the bracket are slidably connected. A compression spring is installed inside the slide cylinder, and a pressure roller is rotatably connected inside the slide block. By rotating the screw and screw cylinder to perform threaded movement, the screw cylinder compresses the compression spring, which in turn elastically compresses the slide block, thereby elastically compressing the pressure roller and ultimately the sole, thus limiting the sole and preventing it from detaching from the support roller.

[0010] Preferably, a sliding pin is fixedly connected to the outer side of the screw barrel, and the sliding pin and the slide barrel are slidably connected. By providing the sliding pin, relative rotation between the screw barrel and the slide barrel is prevented.

[0011] Preferably, one end of the compression spring is fixedly connected to the screw cylinder, and the other end of the compression spring is fixedly connected to the slide block. By setting the compression spring, the slide block is elastically pressed down.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses the rotation of a bidirectional screw and a pressure plate to make a spiral motion, which in turn causes the spring to elastically compress the slide plate, causing the slide plate to drive the change in the distance between the two supports, thus supporting shoe soles of different lengths.

[0014] 2. This utility model uses the rotation of the screw and the screw barrel to make a spiral motion, which causes the screw barrel to squeeze the compression spring, which in turn causes the compression spring to elastically squeeze the slide block, which in turn causes the pressure roller to be elastically squeezed, thus limiting the position of the shoe sole and preventing the shoe sole from detaching from the support roller.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-2 A bending resistance testing device for running shoe soles includes a frame 1. A cylinder 2 is fixedly installed in the middle of the upper end of the frame 1. The cylinder rod of the cylinder 2 passes through the frame 1 and is slidably connected to the frame 1. A pressure strip 3 is fixedly connected to the end of the cylinder rod of the cylinder 2. A bracket 4 is slidably connected to the upper end of the frame 1. A support mechanism 5 is provided on the frame 1. A support roller 6 is provided on the bracket 4. A limit mechanism 7 is provided on the bracket 4.

[0022] Please see Figures 1-3 The support mechanism 5 includes a slide plate 51, which is fixedly connected to the bracket 4 and slidably connected to the frame 1. A bidirectional screw 52 is movably connected inside the slide plate 51. A limit plate 53 is fixedly connected to the lower end of the frame 1. The limit plate 53 and the bidirectional screw 52 are rotatably connected. By setting the limit plate 53, the bidirectional screw 52 is limited. A pressure plate 54 is threadedly connected to the outside of the bidirectional screw 52. The pressure plate 54 is slidably connected to the frame 1. A spring 55 is set on the outside of the bidirectional screw 52. One end of the spring 55 is fixedly connected to the pressure plate 54, and the other end of the spring 55 is fixedly connected to the slide plate 51. By setting the spring 55, the slide plate 51 is elastically supported. By rotating the bidirectional screw 52 and the pressure plate 54 to make threaded movements, the spring 55 elastically compresses the slide plate 51, causing the slide plate 51 to drive the change in the distance between the two brackets 4, which can support shoe soles of different lengths.

[0023] Please see Figure 1 , Figure 3 , Figure 4The limiting mechanism 7 includes a screw 71. The screw 71 is mounted inside the bracket 4 via bearings. A screw cylinder 72 is threadedly connected to the outside of the screw 71. A slide cylinder 73 is slidably connected to the outside of the screw cylinder 72. A sliding pin 74 is fixedly connected to the outside of the screw cylinder 72. The sliding pin 74 and the slide cylinder 73 are slidably connected. By setting the sliding pin 74, relative rotation between the screw cylinder 72 and the slide cylinder 73 is prevented. A slide seat 75 is fixedly connected to the lower end of the slide cylinder 73. The slide seat 75 is slidably connected to the bracket 4. A compression spring 7 is installed inside the slide cylinder 73. 6. One end of the compression spring 76 is fixedly connected to the screw cylinder 72, and the other end of the compression spring 76 is fixedly connected to the slide block 75. By setting the compression spring 76, the slide block 75 is elastically pressed down. The slide block 75 is rotatably connected to the pressure roller 77. By rotating the screw 71 and the screw cylinder 72 to make threaded movement, the screw cylinder 72 squeezes the compression spring 76, which in turn makes the compression spring 76 elastically squeeze the slide block 75, which in turn makes the pressure roller 77 elastically squeezed, which in turn makes the sole of the shoe elastically squeezed, limiting the sole of the shoe and preventing the sole of the shoe from detaching from the support roller 6.

[0024] The specific implementation process of this utility model is as follows: In use, according to the sole length adjustment device, the bidirectional screw 52 is manually rotated. The rotation of the bidirectional screw 52 and the screw plate 54 make a threaded movement, thereby causing the screw plate 54 to move. The movement of the screw plate 54 compresses the spring 55, which in turn causes the spring 55 to elastically compress the slide plate 51. The slide plate 51 drives the bracket 4 to move, causing the distance between the two brackets 4 to change. By rotating the bidirectional screw 52 and the screw plate 54 to make a threaded movement, the spring 55 elastically compresses the slide plate 51, causing the slide plate 51 to drive the distance between the two brackets 4 to change, thus supporting soles of different lengths. Then, manually rotate screw 71. Screw 71 rotates screw barrel 72 in a threaded motion, which in turn causes screw barrel 72 to press down on spring 76. Spring 76 elastically compresses slide block 75, which in turn causes slide block 75 to move and elastically press down on pressure roller 77. This makes the sole of the shoe elastically pressed onto support roller 6. By rotating screw 71 and screw barrel 72 in a threaded motion, screw barrel 72 compresses spring 76, which in turn elastically compresses slide block 75. This makes pressure roller 77 elastically compressed, which in turn makes the sole of the shoe elastically compressed, limiting the sole of the shoe and preventing it from detaching from support roller 6.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
