[0002] The main function of shoelaces is to adjust the tightness of shoes to ensure the comfort and safety of wearing shoes. The traditional shoelace tying process requires two hands to operate at the same time, and the tightness is not easy to adjust. The shoelaces are easy to loosen during walking, causing a lot of inconvenience. Now there is a shoelace buckle on the market that can realize the automatic shoelace tying function. Compared with traditional shoelaces, this shoelace buckle can tie shoelaces quickly, and only one hand is needed to tie shoelaces, and the shoelaces are not easy to loosen, which is convenient and quick.

[0003] Shoelace buckles are easy to use and stylish, and are gaining more and more attention and popularity. Many shoe brands have begun to use shoelace buckles instead of traditional shoelaces. There are various types of shoelace buckles on the market, most of which are made of plastic. Shoelaces are made of polyethylene fiber rope, stainless steel coated steel wire rope, nylon rope and other materials, which have strong corrosion resistance and wear resistance. However, if the shoes you wear use poor quality shoelace buckles, it is easy for the knob to press or rotate, the buckle is not self-locking, and the shoelaces are easy to loosen, which not only affects the comfort of walking, but also poses a safety hazard.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] The present invention provides a shoelace buckle fatigue tester, which is implemented as follows: Figures 1 to 3As shown, it includes a fixing mechanism 10, and a lifting mechanism 20, a rotating mechanism 30 and a clamping mechanism 40 arranged above the fixing mechanism 10; the fixing mechanism 10 is used to clamp and fix the shoelace buckle; the lifting mechanism 20 is connected with the rotating mechanism 30 below, and the lifting mechanism 20 is used to control the rotating mechanism 30 to move toward and away from the fixing mechanism 10, wherein the lifting mechanism 20 is a cylinder or a linear motor, and the telescopic part of the lifting mechanism 20 is connected to the rotating mechanism 30; the rotating mechanism 30 is connected with the clamping mechanism 40 below, and the rotating mechanism 30 is used to control the rotation of the clamping mechanism 40, wherein the rotating mechanism 30 is a motor, and the rotating shaft of the rotating mechanism 30 is connected to the clamping mechanism 40; the clamping mechanism 40 is provided with a clamping claw that opens and closes, and the clamping claw is used to clamp the shoelace buckle; the shoelace buckle fatigue tester is used to control the rotation of the shoelace buckle through the cooperation of the above-mentioned various mechanisms, and obtain the number of rotations required for the shoelace buckle to rotate to failure, or rotate the shoelace buckle a preset number of times.

[0034] The present invention also provides a shoelace buckle fatigue testing method, which uses the above-mentioned shoelace buckle fatigue testing instrument and includes the following steps:

[0035] S1, installing the shoelace buckle on the fixing mechanism 10;

[0036] S2, the lifting mechanism 20 controls the clamping mechanism 40 to move toward the fixing mechanism, and uses the clamping mechanism 40 to clamp the shoelace buckle;

[0037] S3, the rotating mechanism 30 controls the clamping mechanism 40 to rotate, thereby driving the shoelace buckle to rotate, until the shoelace buckle is rotated a required number of times until it fails, or the shoelace buckle is rotated a preset number of times.

[0038] Specifically, when performing failure detection on the shoelace buckle, the shoelace buckle can be placed on the fixing mechanism 10 for fixing. The fixing method can be various forms such as clamping and buckling. The technical personnel in this field can select and design the fixing mechanism 10 according to the needs; after the shoelace buckle is fixed, the lifting mechanism 20 controls the rotating mechanism 30 and the clamping mechanism 40 to move downward, the clamping mechanism 40 controls the clamping claws to clamp the shoelace buckle, and then the rotating mechanism 30 controls the clamping mechanism 40 to rotate as a whole, thereby realizing the pressing and rotation of the shoelace buckle; after each control of the shoelace buckle to rotate one circle, the shoelace buckle fatigue tester will record a rotation operation, and then repeat the pressing and rotating operations until it is measured that the shoelace buckle has failed, then the number of rotations required for the shoelace buckle to rotate to failure can be known.

[0039] Similarly, if the shoelace buckle needs to be tested a preset number of times, the shoelace buckle can also be placed on the fixing mechanism 10 for fixing. After the shoelace buckle is fixed, the lifting mechanism 20 controls the rotating mechanism 30 and the clamping mechanism 40 to move downward, the clamping mechanism 40 controls the clamping claws to clamp the shoelace buckle, and then the rotating mechanism 30 controls the clamping mechanism 40 to rotate as a whole. After the number of rotations reaches the set number, the shoelace buckle is stopped from being controlled to rotate.

[0040] It should be noted that this device can not only test the shoelace buckle individually, but also the whole shoe. For example, when testing a single shoelace buckle, the shoelace buckle only needs to be placed on the fixing mechanism 10 to perform relevant tests. When the whole shoe needs to be tested, Figure 2 As shown, the shoelace buckle fatigue tester of this embodiment also includes a shoe support frame 60, and the shoe support frame 60 is arranged on the base 50. The shoe support frame 60 is provided with a fixing mechanism 10, so the shoe support frame 60 can be used to support the whole shoe. Since the fixing mechanism 10 is arranged on the shoe support frame 60 at this time, it is only necessary to place the shoelace buckle on the whole shoe on the fixing mechanism 10, and the above method can be used to test the whole shoe.

[0041] Specifically, the shoe support frame 60 of this embodiment includes a suspended connecting block 61, a shoe support cantilever 62, a base plate 63, a pushing guide rail 64, a pushing slider 65, a pushing connecting block 66, a pushing rod 67 and a pushing motor 68; the suspended connecting block 61 is arranged on the base 50, and the suspended connecting block 61 is provided with a shoe support cantilever 62; the lower part of the shoe support cantilever 62 is provided with a fixing mechanism 10, and the upper part of the shoe support cantilever 62 is connected with an obliquely arranged base plate 63; the base plate 63 is provided with a pushing guide rail 64; the pushing slider 65 is slidably installed on the pushing guide rail 64; the pushing slider 65 is connected and fixed to the pushing connecting block 66; the pushing connecting block 66 is respectively connected to the pushing rod 67 and the pushing motor 68; the pushing rod 67 is arranged obliquely; the pushing motor 68 is used to drive the pushing rod 67 to push the sole of the shoe to be tested.

[0042] During application, the shoe to be tested is placed on the shoe support frame 60, and the shoelace buckle is ensured to be placed at the position of the fixing mechanism 10, and then the test can be started; at this time, every time the shoelace buckle is controlled to rotate a preset stroke, the pushing motor 68 can control the pushing rod 67 to push down the sole of the shoe to be tested, so as to control the shoelace buckle to recover to a state where it can be rotated again, thereby making it feasible to repeatedly rotate the shoelace buckle.

[0043] Therefore, after adopting the above technical solution, the quality inspection of shoelace buckles will be realized, filling the blank in this technical field and effectively solving the problem that the prior art lacks corresponding devices for inspecting the durability and safety of shoelace buckles.

[0044] like Figure 2 As shown, the shoelace buckle fatigue tester in this embodiment further includes a base 50 , a support arm 51 is disposed on the base 50 , and a lifting mechanism 20 is disposed on the support arm 51 .

[0045] After adopting this arrangement, since the support arm 51 is arranged to extend horizontally and the lifting mechanism 20 is arranged on the end portion of the support arm 51 extending outward, the lifting mechanism 20 is suspended and supported and installed.

[0046] like Figure 2 As shown, in this embodiment, a displacement sensor 52 is arranged on the base 50. Specifically, in this embodiment, the displacement sensor 52 is arranged as a laser sensor, and the lifting and lowering path of the rotating mechanism 30 is placed in the detection area of ​​the displacement sensor 52. According to the detection result of the displacement sensor 52, the shoelace buckle fatigue tester completes one rotation operation of the shoelace buckle by lifting and lowering the rotating mechanism 30 once.

[0047] After adopting this setting method, every time the rotating mechanism 30 passes through the detection area of ​​the displacement sensor 52, the displacement sensor 52 can obtain a corresponding signal. Since when the rotating mechanism 30 performs a lifting operation, it is actually equivalent to completing a rotation operation of the shoelace buckle. Therefore, by using the displacement sensor 52 to detect the lifting and lowering movement of the rotating mechanism 30, the number of rotations of the shoelace buckle can be detected and measured.

[0048] Preferably, in this embodiment, the rotating mechanism 30 is provided with a force detection sensor. Specifically, in this embodiment, the force detection sensor is provided as a torque sensor, and the force detection sensor is used to detect the resistance encountered by the rotating mechanism 30 during the rotation operation; the shoelace buckle fatigue tester determines that the shoelace buckle is in a failed state when the resistance encountered by the rotating mechanism 30 is lower than a preset value based on the detection result of the force detection sensor.

[0049] When the shoelace buckle is not invalid, rotating the shoelace buckle will inevitably encounter a certain resistance. Once the shoelace buckle fails, the shoelace buckle will not be able to be tightened and can only slip and rotate, thereby losing the corresponding resistance. Therefore, by detecting the resistance encountered by the rotating mechanism 30 through the force detection sensor, it can be determined whether the shoelace buckle is in a failed state.

[0050] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
