[0002] In the footwear industry, the laces and eyelets of finished shoes must undergo rigorous testing before being released to the market, with abrasion resistance testing of the eyelets being particularly important. Insufficient abrasion resistance of laces and eyelets can pose serious safety hazards, causing the laces to break and leading to falls. Therefore, abrasion resistance testing of laces and eyelets is essential. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of the prior art and provide an abrasion resistance testing machine that can test multiple sets of shoelaces and buckles at the same time and is convenient for fixing shoelaces and buckles.

[0004] To achieve the above objectives, the present invention adopts the following solution:

[0005] A shoe buckle abrasion resistance testing machine includes: a frame, multiple slide rails on the left and right sides of the frame, sliders connected to the slide rails, a connecting frame connecting two sliders, multiple connecting blocks on the connecting frame, a first clamping groove on each connecting block for clamping shoelaces, a mounting base on the frame, multiple clamping plates on the mounting base, multiple locking positions on the clamping plates for shoe buckles to engage, multiple sliding grooves for shoelaces to pass through and slide, a locking element connected to the clamping plate for positioning and clamping the shoe buckle to prevent it from disengaging from the locking position, and drive components on both the left and right sides of the frame for reciprocating movement of the connecting frame.

[0006] The aforementioned slot is a mounting groove provided on the mounting base. The opening of the mounting groove faces upward, and the mounting groove has a first groove for placing the shoe buckle head and a second groove for accommodating the shoe buckle body. The first groove and the second groove are interconnected.

[0007] The slide groove is arranged parallel to the mounting groove, and the width of the slide groove is smaller than the width of the second groove, so that the top surface of the slide groove can abut against the shoe buckle.

[0008] The clamping plate is provided with a support plate on one side of the slide groove, which can support the shoelaces. The middle part of the mounting base is also provided with a rotating wheel that can rotate relative to it. The rotating wheel is provided with a first guide groove that can guide the shoelaces to slide.

[0009] The support plate is bent downward at the end away from the slide groove to form an arc-shaped support surface. The rotating wheel is provided with a second clamping groove that allows one end of the shoelace to be inserted. The clamping plate is also provided with a plurality of first mounting holes. The top of the rotating wheel is provided with a protruding connecting part.

[0010] The clamping plate has outwardly extending connecting arms at its four corners. The connecting arms are detachably connected to the mounting base by screws, and the mounting base is also provided with positioning grooves that allow the clamping plate to be inserted.

[0011] The clamping plate has arc-shaped connecting parts at its left and right ends, and the connecting arms are arranged at intervals at the upper and lower ends of the arc-shaped connecting parts.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] like Figures 1 to 5 As shown, a shoe buckle abrasion resistance testing machine includes: a frame 1, multiple slide rails 11 on the left and right sides of the frame 1, sliders 12 connected to the slide rails 11, a connecting frame 2 connected between two sliders 12, multiple connecting blocks 21 on the connecting frame 2, a first clamping groove 211 on the connecting block 21 for clamping shoelaces, a mounting base 3 on the frame 1, multiple clamping plates 4 on the mounting base 3, multiple locking positions 41 on the clamping plates 4 for shoe buckles to be inserted, multiple sliding grooves 42 for shoelaces to be threaded through and slide, a locking member 43 connected to the clamping plate 4 for positioning and clamping the shoe buckle and preventing the shoe buckle from disengaging from the locking position 41, and drive components 5 on both the left and right sides of the frame 1 for driving the connecting frame 2 to reciprocate.

[0025] When testing is required, place the two shoe buckles in the two slots 41, then thread the shoelaces so that the two ends of the shoelaces are connected to the first clamping grooves 211 respectively. Then, start the drive assembly 5 to make the two connecting frames 2 slide back and forth. At this time, the shoelaces move back and forth and rub against the eyelets to test the abrasion resistance of the shoelaces and eyelets. Moreover, since multiple clamping plates 4 are set up, multiple sets of tests can be performed at one time, which not only improves the efficiency of the test, but also allows for multiple sets of comparisons, thus improving the accuracy of the test results.

[0026] The locking position 41 is a mounting groove provided on the mounting base 3. The opening of the mounting groove faces upward, and the mounting groove has a first groove 411 for placing the shoe buckle head and a second groove 412 for accommodating the shoe buckle body. The first groove 411 and the second groove 412 are interconnected. This facilitates the positioning and locking of the shoe buckle, and makes installation and positioning convenient.

[0027] The sliding groove 42 is parallel to the mounting groove, and the width of the sliding groove 42 is smaller than the width of the second groove 412, so that the top surface 421 of the sliding groove 42 can abut against the shoe buckle. The top surface 421 prevents the shoe buckle from sliding within the sliding groove 42, and the locking member 43 prevents the shoe buckle from wobbling up and down, making installation and positioning more convenient. The locking member 43 is a screw.

[0028] The clamping plate 4 is located on one side of the slide groove 42 and has a support plate 44 for supporting the shoelaces. The mounting base 3 also has a rotating wheel 45 in the middle that can rotate relative to it. The rotating wheel 45 has a first guide groove 451 for guiding the shoelaces to slide. The cooperation of the support plate 44 and the rotating wheel 45 can effectively guide the sliding direction of the shoelaces, making the shoelaces smoother during the tidying process. At the same time, it can prevent the shoelaces from bending, twisting or wearing out due to lack of support on one side of the slide groove 42.

[0029] The support plate 44 is bent downwards at the end away from the slide groove 42, forming an arc-shaped support surface 441. The rotating wheel 45 is provided with a second clamping groove 452 for one end of the shoelace to be inserted. The clamping plate 4 is also provided with multiple first mounting holes 46. The top of the rotating wheel 45 is provided with a protruding connecting part 453. In another case, a motor bracket is connected through the first mounting hole 46, and then a motor is installed on the motor bracket. Connecting the output shaft of the motor to the connecting part 453 allows the other end of the shoelace to be inserted into the second clamping groove 452. Because the length of the shoelace is reduced, it becomes shorter, allowing for a higher testing frequency and facilitating high-frequency testing. The arc-shaped support surface 441 guides the shoelace, making its movement smoother.

[0030] The clamping plate 4 has outwardly extending connecting arms 47 at its four corners. These connecting arms 47 are detachably connected to the mounting base 3 via screws. The mounting base 3 also has positioning grooves 31 into which the clamping plate 4 can be engaged. This connection method, with the connecting arms 47 extending outwards from the four corners and detachably connected to the mounting base 3 via screws, allows the clamping plate 4 to be fixed from multiple directions, forming a stable support.

[0031] The clamping plate 4 has arc-shaped connecting portions 48 at its left and right ends, and connecting arms 47 are spaced vertically at the upper and lower ends of the arc-shaped connecting portions 48. The positioning groove 31 has a top support surface 311 on its groove wall to support the arc-shaped connecting portions 48. The design of the arc-shaped connecting portions 48 and the top support surface 311 allows the clamping plate 4 to be quickly positioned during installation, eliminating the need for complex alignment operations and improving installation efficiency.

[0032] The drive assembly 5 includes a drive motor 51 connected to the frame 1. The output shaft of the drive motor 51 is connected to a turntable 52 that can rotate with it. The turntable 52 is provided with a protruding post 521. The connecting frame 2 is provided with a movable groove 22 that can accommodate the post 521 and allow the post 521 to move within it. The post 521 is offset from the rotation axis of the turntable 52.

[0033] Due to the arrangement of slider 12 and slide rail 11, the protruding post 521 can push the connecting frame 2 to move back and forth relative to the frame 1 along a preset trajectory during the rotation of turntable 52. The movable groove 22 is a strip groove.

[0034] The movable groove 22 has a first abutting surface 221 and a second abutting surface 222 that can abut against the protrusion 521 to drive the connecting frame 2 to move. The first abutting surface 221 and the second abutting surface 222 can abut against the protrusion 521 respectively, thereby driving the connecting frame 2 to slide left and right relative to the frame 1.

[0035] The connecting block 21 is also provided with a second guide groove 212 for the movement of the shoelaces. The second guide groove 212 is connected to the first clamping groove 211. The second guide groove 212 is used to position the shoelaces. Before the shoelaces pass through the clamping groove, the second guide groove 212 can guide the shoelaces into the clamping groove, ensuring that the shoelaces are accurately positioned when entering the clamping groove. At the same time, the end of the shoelace can be placed into the first clamping groove 211 and then secured with a cylindrical snap fastener, or the end of the shoelace can be knotted and then placed into the first clamping groove 211 for fixation.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
