Technical Field

[0001] This application relates to the field of footwear testing technology, specifically to a footwear flexural endurance testing machine. Background Technology

[0002] The flexural strength of footwear is one of the important indicators for measuring the quality of footwear products, which directly affects the lifespan and comfort of the shoes.

[0003] Traditional footwear flexural endurance testing relies heavily on manual operation or simple mechanical devices, resulting in low testing efficiency, poor repeatability, and improper operation. Furthermore, existing equipment often cannot simulate the multi-angle bending during actual wear, leading to discrepancies between test results and real-world conditions.

[0004] Therefore, there is an urgent need for a footwear flexural endurance testing machine with a reasonable structure, convenient operation, and high testing accuracy to improve the standardization and automation level of footwear quality inspection. Utility Model Content

[0008] The mounting housing has a door panel hinged to its front side;

[0009] A cylinder is installed on the inner side of the mounting shell, and a mounting block is installed on the upper end of the moving end of the cylinder. Bending columns are installed on the front side of the mounting block and the moving end of the cylinder, and the individual bending columns are distributed on the upper and lower sides of the sole of the shoe to be tested.

The two ends of the spring on the outer side of the limit rod are respectively connected to the inner side of the mounting base and the lower side of the lower clamping plate, so that the lower clamping plate and the mounting base form an elastic connection. An adjusting rod is rotatably connected to the upper end of the lower clamping plate, and an upper clamping plate is threadedly connected to the outer side of the adjusting rod. A limiting post fixed to the upper end of the lower clamping plate is provided on one side of the adjusting rod, and the limiting post and the upper clamping plate form a slidable connection.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] The present invention provides a footwear flexural endurance testing machine, including a mounting shell 1, a door panel 2 hinged to the front side of the mounting shell 1, the door panel 2 being able to close the mounting shell 1, and a viewing glass 3 installed on the inner side of the door panel 2, which can visualize the inside of the mounting shell 1, allowing the operator to observe from the outside.

[0030] A cylinder 6 is installed on the inner side of the housing 1. An installation block 7 is installed on the upper end of the moving end of the cylinder 6. A bending column 8 is installed on the front side of the installation block 7 and the moving end of the cylinder 6. The bending column 8 is distributed on the upper and lower sides of the sole of the shoe to be tested, so that when the cylinder 6 moves up and down, it can drive the middle part of the sole to bend up and down.

[0031] The mounting block 7 and the moving end of the cylinder 6 are designed separately. The inner side of the mounting block 7 is threaded with an adjusting column 9. The lower end of the adjusting column 9 is rotatably connected to the cylinder 6. Rotating the adjusting column 9 can adjust the height of the mounting block 7, thereby adjusting the spacing between the individual bending columns 8.

[0032] A positioning column 10 is also provided on one side of the adjusting column 9, which is slidably installed inside the mounting block 7. The lower end of the positioning column 10 is fixedly installed with the upper end of the moving end of the cylinder 6, thus restricting the deflection movement of the mounting block 7.

[0033] Clamping mechanisms 5 are installed on the inner walls of both the left and right sides of the mounting housing 1 to clamp the two ends of the shoe sole to be tested, and the cylinder 6 is located in the center of the mounting housing 1.

[0034] The clamping mechanism 5 includes a mounting base 501. A limiting rod 502 is fixed to the inner side of the mounting base 501. A spring is installed on the outer side of the limiting rod 502. A lower clamping plate 503 is slidably installed on the outer side of the limiting rod 502. The two ends of the spring on the outer side of the limiting rod 502 are respectively connected to the inner side of the mounting base 501 and the lower side of the lower clamping plate 503, so that the lower clamping plate 503 and the mounting base 501 form an elastic connection. An adjusting rod 505 is rotatably connected to the upper end of the lower clamping plate 503. An upper clamping plate 504 is threadedly connected to the outer side of the adjusting rod 505. A limiting post 506 is fixed to the upper end of the lower clamping plate 503 on one side of the adjusting rod 505. The limiting post 506 and the upper clamping plate 504 form a sliding connection, so that the distance between the upper clamping plate 504 and the lower clamping plate 503 can be adjusted, thereby clamping the shoe sole to be tested.

[0035] The lower end of the upper clamping plate 504 is also fixed with several puncture needles 508, and the upper side of the lower clamping plate 503 is provided with a hole-like structure corresponding to the puncture needles 508. The puncture needles 508 are used to puncture the sole of the shoe to be tested to increase the clamping stability.

[0036] The outer end of the mounting base 501 is rotatably connected to the connecting base 507. One end of the connecting base 507 is fixedly installed on the inner wall of the mounting housing 1, so that the mounting base 501 can rotate. Thus, during the bending of the shoe sole, the mounting base 501 can adapt to the tilt angle of the shoe sole and reduce the friction between the lower clamping plate 503 and the limiting rod 502 during the test.

[0037] A counter 4 is also provided on one side of the cylinder 6 to detect the number of times the cylinder 6 is started, thereby monitoring the number of times the sole of the shoe under test can withstand bending.

[0038] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
