Description

Technical Field

[0001] This utility model relates to the technical field of fatigue testing devices, specifically to a fatigue testing device for casual shoes. Background Technology

[0002] Fatigue resistance testing for casual shoes assesses their durability and fatigue resistance by simulating the repeated pressure and bending experienced by the heel during daily wear. This test aims to verify that the heel maintains good support and shape stability after prolonged use, reducing the risk of wear, deformation, or breakage. Common fatigue resistance testing for casual shoes requires specialized fatigue testing equipment. Its core function is to mechanically simulate the stress state of the heel during walking and running, testing the wear, deformation, or damage of the material after thousands of cycles of loading, thereby determining its fatigue resistance.

[0003] Chinese utility model patent CN207639745U discloses a device for detecting the fatigue cycles of shoes, including "an adjustment mechanism disposed on the fixed frame, a rotating mechanism rotatably connected to the fixed frame, a magnetic clamping block disposed on the adjustment mechanism, a forefoot placement plate disposed on the fixed frame, a heel placement plate disposed on the rotating mechanism, a first rotating rod connected to one end of the heel placement plate and one end of the second rotating rod respectively, and a magnetic clamping block rotatably connected to the other end of the second rotating rod"; however, the heel is only fixed by magnetic adsorption. During the fatigue test, the shoe is prone to shifting in the testing device due to the overall force on the shoe, which in turn affects the testing effect of the device. Utility Model Content

[0004] The purpose of this invention is to provide a fatigue testing device for casual shoes, in order to solve the problem mentioned in the background art that, when the heel is fixed by magnetic adsorption alone, the shoe will shift in the testing device due to force during the fatigue testing process, which will affect the testing effect of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fatigue detection device for casual shoes, comprising a support base, a support frame installed inside the support base, a rotating motor installed on one side of the bottom of the support frame, a rotating plate driven by the rotating motor, a fixed base installed at the top center of the rotating plate, a fixed frame installed on the top of the fixed base, an electric push rod installed at the top center of the fixed frame, and a pressing block driven by the bottom of the electric push rod.

[0006] Limiting plates are installed on both sides of the support base, and limiting grooves are penetrated through the interior of the limiting plates. The support base is an L-shaped frame structure, and a shoe toe block is installed at the top center of the horizontal plate below the support base. A lifting motor is installed on the top back of the support base. One end of the lifting motor is driven and connected to a wheel. A fixed rotating rod is installed on the front of the wheel. The rotation of the fixed rotating rod is connected to one end of the lifting rotating rod, and the other end of the lifting rotating rod is rotatably connected to a connecting seat.

[0007] A heel stop is installed at one top end of the fixed base, a limit groove is embedded in the top of the fixed base, a clamping motor is installed on one side of the fixed base, one end of the clamping motor is driven and connected to a bidirectional lead screw, and the two ends of the bidirectional lead screw are threadedly connected to clamping plates.

[0008] The beneficial effects of this utility model are as follows: by setting a motor-driven clamping plate at the heel to clamp the heel of the shoe, and cooperating with the push rod to push the extrusion block to extrude and fix the sole to the fixed base, the shoe is further fixed, thereby preventing the shoe from shifting during fatigue testing and improving the detection effect of the testing device. At the same time, a rotatable rotating plate is set at the bottom of the fixed base, so that the shoe can tilt and press against the toe block at the bottom during testing, further simulating the angle of actual human use, thereby improving the detection effect of the testing device.

[0009] To ensure the stability of the shoe's position during fatigue testing:

[0010] The support frame is further configured as follows: the support frame is a U-shaped frame structure with the opening facing downwards, and limit blocks are respectively installed on the top two sides of the support frame. The limit blocks are I-shaped cross-section structures, and the limit blocks and the limit grooves form a sliding connection structure.

[0011] By adopting the above technical solution, a limiting plate is set in conjunction with a limiting groove to limit the lifting position of the limiting blocks on both sides of the support frame, so as to prevent the support frame from shifting during the lifting process, thereby stabilizing the position of the shoes inside the support frame during fatigue testing and improving the detection accuracy of the testing device.

[0012] To enable the rotating wheel to drive the support frame to rise and fall:

[0013] The configuration is further defined as follows: the fixed rotating rod is installed at an eccentric position on the front end face of the rotating wheel, and the bottom of the connecting seat is fixedly connected to the top center of the support frame. When the fixed rotating rod on the front of the rotating wheel is at its highest point, the limiting block is located at the top of the limiting groove, and when the fixed rotating rod is at its lowest point, the limiting block is located at the bottom of the limiting groove.

[0014] By adopting the above technical solution, a fixed rotating rod is set at the eccentric position of the rotating wheel, and a lifting rotating rod and a connecting seat are rotatably connected. While the rotating wheel is rotating, the lifting rotating rod pulls the support frame at the bottom to perform reciprocating lifting and lowering operations, thereby meeting the reciprocating compression requirements of fatigue resistance testing and improving the stability of shoes during fatigue resistance testing.

[0015] To simulate the angles of actual human use during shoe testing:

[0016] Further configuration: the rotating plate is connected to the inner walls of the bottom two ends of the support frame via a drive motor to form a rotating connection structure; the inner wall of the heel abutment is an arc-shaped structure; the fixing frame is a U-shaped frame structure with the opening facing downwards; and when the electric push rod is at its maximum extension distance, the bottom of the pressing block and the top of the fixing base are in contact with each other.

[0017] By adopting the above technical solution, a rotating plate is set to drive the shoe to adjust its angle to simulate the angle when the human body is actually using it, thereby improving the detection accuracy of the detection device. At the same time, the electric push rod pushes the clamping block into the shoe to squeeze and fix the heel of the shoe to the fixed base, thereby preventing the shoe from shifting due to the squeezing force when the shoe is subjected to fatigue test, and improving the stability of the detection device during use.

[0018] To further secure the shoes within the testing device:

[0019] The configuration is further defined as follows: both ends of the bidirectional lead screw are provided with opposite external thread structures on their outer walls, and the bidirectional lead screw is rotatably connected to the inside of the limiting slide groove, and the external thread structures of the bidirectional lead screw are all located inside the limiting slide groove; the clamping plate has a T-shaped cross-section structure, and the bottom of the clamping plate is connected to the bidirectional lead screw and the limiting slide groove through a thread to form a sliding connection structure; the lifting motor, the rotating motor and the clamping motor are all servo motors.

[0020] By adopting the above technical solution, a motor-driven clamping plate is set to clamp and fix the outer wall of the shoe heel, which makes it easy to adjust the clamping distance according to the shoe specifications. In conjunction with an adjustable pressing block, the heel is vertically squeezed and fixed, further fixing the shoe in the detection device, thereby improving the stability of the shoe during detection.

[0021] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0038] Therefore, the "lifting motor," "rotating motor," "clamping motor," and "electric push rod" mentioned in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, an improvement in the overall structure of the fatigue detection device of this application, in order to solve the corresponding technical problems to be solved by this application.

[0039] The fatigue detection device for casual shoes operates as follows:

[0040] First, place the heel of the casual shoe to be tested at the center of the top of the fixed base 5. Then, align the outer wall of the heel of the casual shoe with the arc-shaped inner wall of the heel abutment 501. Start the clamping motor 503 (model: MS1-R) on one side of the fixed base 5 to drive the bidirectional lead screw 504 to rotate, causing the bottom of the clamping plates 505 at both ends to slide within the two limit grooves 502.

[0041] Then, the clamping plate 505 clamps and fixes the outer walls of both sides of the shoe heel. At the same time, the electric push rod 7 (model: LAP63) at the top center of the fixing frame 6 is activated to push the bottom pressing block 8 from the shoe opening into the shoe to squeeze and fix the shoe heel, thus fixing the shoe in the fixing base 5.

[0042] Next, start the rotating motor 3 (model: MS1-R) to drive the rotating plate 4 to rotate at the bottom of the support frame 2, causing the fixed base 5 at the top of the rotating plate 4 to tilt so that the toe of the shoe is directly above the toe block 103. Start the lifting motor 104 (model: MS1-R) on the back of the top of the support base 1 to drive the rotating wheel 105 to rotate at the top of the front of the support base 1. At this time, the fixed rotating rod 106 fixed at the eccentric position on the rotating wheel 105 drives the connecting seat 108 connected to the other end of the lifting rotating rod 107 to perform up and down reciprocating lifting operations through the rotating rod 107.

[0043] Finally, the support frame 2, which is fixedly connected to the bottom of the connecting seat 108, moves up and down between the limiting plates 101 under the action of the limiting blocks 201 and the limiting grooves 102 on both sides. This causes the shoe toe and the shoe toe block 103 in the fixed base 5 to be squeezed, thereby testing the anti-fatigue effect of the shoe. After multiple compressions, the wear, deformation or damage of the shoe is observed to determine the anti-fatigue performance of the shoe.
