Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and more specifically, to a device for testing the abrasion resistance of mesh fabric for shoe uppers. Background Technology

[0002] Fabrics with perforations are called mesh fabrics, which are divided into woven mesh fabrics, knitted mesh fabrics, and non-woven mesh fabrics. Woven and machine-woven mesh fabrics are more commonly used due to their good breathability and wide range of applications. Mesh fabric materials are needed to make shoe uppers in the production process of athletic shoes. However, due to the perforated nature of athletic shoe mesh fabrics, their low strength and susceptibility to tearing are significant drawbacks. Therefore, specialized testing equipment is required to test the abrasion resistance of mesh fabrics used in shoe uppers.

[0003] For example, patent number CN219552135U discloses a sports shoe bending test mechanism, including a support base with multiple suction cups below it. The support base is connected to a top plate via a support vertical plate. A servo motor is located inside the top plate, and the output shaft of the servo motor is connected to a one-way spiral rod. A movable block is sleeved on the one-way spiral rod, and an electro-hydraulic push rod is fixed below the movable block. The electro-hydraulic push rod is connected to multiple bending test blocks via a movable horizontal plate. Multiple fixed rods are fixed above the support base, and foot models are connected to the fixed rods via fixed bolts. A rotating ring is fixed to one side of the fixed bolts, and a sports shoe body is sleeved on the foot model. A camera is connected to the top plate via an elastic column. Multiple support horizontal plates are fixed to one side of the support base, and a sample storage box is located above the support horizontal plates. This utility model provides a sports shoe bending test mechanism that can test shoes of different sizes and models, has a simple structure, and is easy to operate.

[0004] In the aforementioned patent, the inventor believes that although the patent meets the needs of bending tests for shoes of different sizes, the mesh fabric of mesh shoes is particularly prone to damage at the flexion point of the shoe. At the same time, because the force points of users' feet vary when walking, and existing technologies for bending tests of sports shoes have the problem that the force points of bending drive are not easy to adjust, that is, the flexing movement of the shoe upper is relatively simple, so the data of mesh fabric in abrasion resistance tests is not comprehensive enough.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that addresses the problem of inconvenient adjustment of the bending drive force point during sports shoe bending tests, resulting in insufficient data during mesh abrasion resistance tests.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a test device for abrasion resistance of mesh fabric for shoe uppers, comprising a workbench, a pad for inserting into a mesh shoe on the workbench, a toe-fixing structure on the workbench, the toe-fixing structure fixing the toe of the mesh shoe by indirectly contacting the pad, a pair of rotating seats fixedly connected to the workbench, a rectangular rotating rod rotatably connected to the pair of rotating seats, and a swinging structure for driving the rectangular rotating rod to swing back and forth on the workbench;

[0008] A pair of shoe length adjustment structures are movably connected to the rectangular rotating rod. The shoe length adjustment structure is provided with a shoe heel fixing structure for fixing the heel of the mesh shoe. The rectangular rotating rod is also provided with a pressure point adjustment structure, which is connected to the pair of shoe length adjustment structures.

[0009] In a preferred embodiment, the toe-pressing structure includes a telescopic device, which is fixedly mounted on the workbench. A bracket is fixedly connected to the output end of the telescopic device, and a pair of pressing blocks are fixedly connected to the bottom of the bracket. The pressing blocks achieve indirect contact with the pad by pressing them onto the upper of the mesh shoe.

[0010] In a preferred embodiment, the swing structure includes a second telescopic device, which is fixedly connected to the side of the workbench. A rack is fixedly connected to the output end of the second telescopic device, and a gear is meshed on the rack. The gear is coaxially fixedly connected to one end of the rectangular rotating rod.

[0011] In a preferred embodiment, the shoe length adjustment structure includes a first slide block, which is slidably connected to the rectangular rotating rod. A rectangular sliding rod is fixedly connected to the side of the first slide block, and a second slide block is slidably connected to the rectangular sliding rod. A wing bolt is threaded onto the second slide block and the rectangular sliding rod.

[0012] In a preferred embodiment, the side of the rectangular slide bar is provided with several threaded grooves, and one end of the wing bolt passes through the slide block and is threaded into one of the threaded grooves.

[0013] In a preferred embodiment, the shoe heel fixing structure includes a U-shaped bracket, which is fixedly connected to the slide block two. A pair of anti-slip blocks are provided on the inner side of the bracket, one of which is fixedly connected to a lead screw two, which is threaded onto the bracket. The other anti-slip block is fixedly connected to the inner bottom of the bracket. The pair of anti-slip blocks are respectively used to abut against the inner and outer sides of the heel of the mesh shoe.

[0014] In a preferred embodiment, the pressure point adjustment structure includes a connecting frame, which is fixedly connected to the rectangular rotating rod. A lead screw is rotatably connected to the inner side of the connecting frame, and a pair of rectangular sliding rods are threadedly connected to the lead screw.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This abrasion resistance testing device for shoe uppers uses a pad and a toe-pressing structure to effectively fix the toe of the mesh shoe, while the heel fixing structure can clamp and fix the toe of the mesh shoe on the inner and outer sides. By effectively fixing the toe and heel of the mesh shoe, the reciprocating rectangular rotating rod can control the mesh shoe to simulate the flexion of the upper. In this way, the reciprocating bending of the mesh shoe can be used to test the abrasion resistance of the mesh at the bending point.

[0017] 2. This abrasion resistance testing device for shoe upper mesh fabric, by setting an adjustable length and distance structure, facilitates the adjustment of the distance between the heel fixing structure and the toe pressing structure, thus adapting to mesh fabric shoes of different lengths for abrasion resistance testing.

[0018] 3. This abrasion resistance testing device for shoe uppers, by setting a pressure point adjustment structure, facilitates the adjustment of the position of the shoe heel fixing structure in the lateral direction. The purpose is to adjust the position of the shoe heel fixing structure relative to the shoe heel fixing point, that is, to change the force point of the shoe heel fixing structure reciprocating to pull the shoe heel. Under the constraint of the shoe toe fixing structure on the shoe toe, this makes it easier to adjust the angle of flexion movement of the mesh shoe, thereby improving the comprehensiveness of abrasion resistance test data.

Detailed Implementation

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See also Figures 1-5 This utility model provides a test device for abrasion resistance of mesh fabric for shoe uppers, including a workbench 1, on which a pad 2 for inserting into the mesh fabric shoe is provided.

[0028] The pad 2 can be inserted into the toe of the mesh shoe to facilitate shaping and support of the mesh shoe and prevent deformation during subsequent toe compression. In this application, two pads 2 can be provided so that the mesh abrasion resistance testing device can conduct mesh abrasion resistance tests on two mesh shoes at the same time.

[0029] In this embodiment: a shoe toe clamping structure 3 is mounted on the workbench 1. The shoe toe clamping structure 3 fixes the shoe toe of the mesh shoe through indirect contact pad 2. The shoe toe clamping structure 3 includes a telescopic device 31, which is fixedly mounted on the workbench 1. A bracket 32 ​​is fixedly connected to the output end of the telescopic device 31. A pair of clamping blocks 33 are fixedly connected to the bottom of the bracket 32. The clamping blocks 33 achieve indirect contact with the pad 2 by clamping the upper of the mesh shoe.

[0030] Telescopic device 31 uses a telescopic motor. Telescopic device 31 can be fixedly mounted on workbench 1 by fasteners. When pad 2 is inserted into the toe position of the mesh shoe and placed on the top of workbench 1, telescopic device 31 can control a pair of pressure blocks 33 to descend synchronously. The pressure blocks 33 press tightly and can indirectly abut against pad 2 on the shoe surface of the mesh shoe toe, thus fixing the toe of the mesh shoe without deformation.

[0031] In this embodiment: a pair of rotating seats 4 are fixedly connected to the workbench 1, and a rectangular rotating rod 5 is rotatably connected to the pair of rotating seats 4. The workbench 1 is provided with a swing structure 6 that drives the rectangular rotating rod 5 to swing back and forth. The swing structure 6 includes a telescopic device 61, which is fixedly connected to the side of the workbench 1. A rack 62 is fixedly connected to the output end of the telescopic device 61, and a gear 63 is meshed on the rack 62. The gear 63 is coaxially fixed to one end of the rectangular rotating rod 5.

[0032] Telescopic device 2 61 also uses a telescopic motor as the telescopic power device. The reciprocating telescopic action of its output end can drive the rack 62 to reciprocate and mesh with the gear 63. Since the gear 63 is coaxially fixed to one end of the rectangular rotating rod 5 through the gear shaft, and since the rectangular rotating rod 5 is rotatably connected to a pair of rotating seats 4 through bearings, the reciprocating gear 63 can drive the rectangular rotating rod 5 to reciprocate and rotate. This rotational power can provide power for the mesh shoe to simulate the bending and flexing of the shoe upper.

[0033] In this embodiment: A pair of shoe length adjustment structures 7 are movably connected to the rectangular rotating rod 5. The shoe length adjustment structure 7 includes a first slide block 71, which is slidably connected to the rectangular rotating rod 5. A rectangular slide rod 72 is fixedly connected to the side of the first slide block 71. A second slide block 73 is slidably connected to the rectangular slide rod 72. A wing bolt 74 is threadedly connected to the second slide block 73 and the rectangular slide rod 72.

[0034] The setting of slide block 71 can conveniently limit the sliding direction of rectangular slide rod 72 on rectangular rotating rod 5. Slide block 73 is connected to rectangular slide rod 72 by wing bolt 74, which can conveniently adjust the usage position of slide block 73.

[0035] In this embodiment: the side of the rectangular slide bar 72 is provided with several threaded grooves, and one end of the wing bolt 74 passes through the slide block 73 and is threaded into one of the threaded grooves.

[0036] The multiple threaded grooves provide multiple fixing points for the wing bolt 74, which allows for convenient and flexible limitation of the position of the slide block 73.

[0037] In this embodiment: the shoe length adjustment structure 7 is provided with a shoe tail fixing structure 9 for fixing the shoe tail of the mesh shoe. The shoe tail fixing structure 9 includes a U-shaped card seat 91, which is fixedly connected to the slide seat 73. A pair of anti-slip blocks 92 are provided on the inner side of the card seat 91. A screw rod 93 is fixedly connected to one of the anti-slip blocks 92, and the screw rod 93 is threadedly connected to the card seat 91. The other anti-slip block 92 is fixedly connected to the inner bottom position of the card seat 91. The pair of anti-slip blocks 92 are respectively used to abut against the inner and outer sides of the shoe tail of the mesh shoe.

[0038] In use, after the toe of the mesh shoe is fixed, the card holder 91 can be positioned at the heel of the mesh shoe. By placing the anti-slip block 92 at the bottom of the shoe, and fixing a rotating head at the end of the screw rod 93 facing away from the anti-slip block 92, the screw rod 93 can drive the anti-slip block 92 at the top to press against the inside of the heel of the mesh shoe through the threaded transmission on the card holder 91. In this way, a pair of anti-slip blocks 92 can stabilize the movement of the heel of the mesh shoe. By fixing the toe and heel of the mesh shoe, the frequency of the reciprocating rotation of the rectangular rotating rod 5 can be set to simulate the flexing of the mesh shoe upper, so as to conduct a wear resistance test on the mesh fabric of the mesh shoe.

[0039] It is worth noting that since the slide seat 2 73 can be adjusted in a straight line, the distance between the shoe heel fixing structure 9 and the shoe toe pressing structure 3 can be easily adjusted, which makes it suitable for testing the abrasion resistance of mesh shoes of various lengths.

[0040] In this embodiment: a pressure point adjustment structure 8 is also provided on the rectangular rotating rod 5. The pressure point adjustment structure 8 is connected to a pair of shoe length adjustment structures 7. The pressure point adjustment structure 8 includes a connecting frame 81, which is fixedly connected to the rectangular rotating rod 5. A lead screw 82 is rotatably connected to the inner side of the connecting frame 81. A pair of rectangular sliding rods 72 are threadedly connected to the lead screw 82.

[0041] In this application, one end of the lead screw 82 is also equipped with a rotating head. By controlling the rotating head, the lead screw 82 is driven to rotate forward or backward. Under the action of the slide block 71 sliding on the rectangular rotating rod 5, the pair of rectangular slide rods 72 threadedly connected to the lead screw 82 can move. Therefore, the positions of the anti-slip block 92 and the pressure block 33 can be adjusted in a staggered manner to change the force point of the anti-slip block 92 on the heel of the mesh shoe. Under the limitation of the shoe toe fixing structure 3 on the shoe toe, it is convenient to adjust the angle of the flexural movement of the mesh shoe. Compared with the traditional method of performing a single-angle bending test on the mesh shoe, this can improve the comprehensiveness and diversity of the wear resistance test data.
