Description

Technical Field

[0001] This utility model relates to the field of clothes hanger manufacturing technology, specifically to a structure for testing the tensile strength of clothes hanger hooks. Background Technology

[0002] As a common drying tool in daily life, the structural strength of clothes hangers directly affects their service life and practicality. In the clothes hanger manufacturing process, tensile testing is a crucial step in evaluating their durability and deformation performance. In existing technologies, tensile testing of clothes hangers typically involves fixing the hanger with clamping equipment or hooks, then applying tension in the opposite direction and observing the deformation of the hanger under the applied force.

[0003] However, existing clamping devices typically apply force through a single clamping point or hook when fixing clothes hangers. This force is concentrated in a local area of ​​the hanger. This testing method simulates a point load, while in actual use, the hanger bears a surface load or line load distributed across the entire frame by the weight of the clothes. Due to the difference in force patterns, existing testing methods cannot truly reflect the deformation characteristics of the hanger in actual drying scenarios, resulting in a discrepancy between the test results and actual performance. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a tensile strength test structure for clothes hangers to solve the problem that existing test methods cannot truly reflect the deformation characteristics of clothes hangers in actual drying scenarios, resulting in deviations between test results and actual performance.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a clothes hanger hook tensile strength testing structure, comprising:

[0006] Base:

[0007] The first cylinder gripper is fixed on the base, wherein the cylinder gripper includes two grippers that move in opposite or opposite directions;

[0008] A limiting clamp includes two sets of limiting components arranged in a mirror symmetrical manner, and the two sets of limiting components are respectively disposed on one side of two grippers. Each set of limiting components includes a first fang plate, a second fang plate, and a third fang plate, all of which are in the shape of a fang. The first fang plate is fixed to one side of each gripper, and the second fang plate slides inside the two sides of the first fang plate respectively.

[0009] A lifting assembly, wherein the lifting assembly is mounted on the base;

[0010] The second cylinder gripper is arranged vertically opposite to the first cylinder gripper and is mounted on the lifting end of the lifting assembly.

[0011] The beneficial effects of this utility model are:

[0012] 1) By utilizing the displacement of the gripper of the first cylinder in opposite directions, the two first plates move closer together, firmly locking the bottom edge of the hanger into the limiting fixture composed of the first, second, and third plates. Through the sliding structure of the second and third plates inside the first plates on both sides, the contact area with the bottom edge of the hanger can be flexibly adjusted, thereby changing the coverage of the clamping force. This breaks through the limitations of the traditional single clamping point, transforming the point load test into a line load test, and more realistically simulating the stress state of the uniform distribution of clothing weight on the hanger edge. It can accurately reflect the deformation of the hanger in actual use, providing more reliable data support for product quality assessment.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the lifting assembly includes a lifting chamber, a slide rail, a lead screw, a motor, a nut, a support arm, and a slider. The lifting chamber is fixed on the base, and the slide rail is formed on one side of the lifting chamber.

[0015] Furthermore, the motor is fixed at the bottom inside the lifting chamber, one end of the lead screw is fixed on the output shaft of the motor, and the other end of the lead screw is rotatably connected to the top inside the lifting chamber via a rotating shaft.

[0016] Furthermore, the nut is screwed onto the outside of the lead screw, the slider slides on the groove of the lifting chamber, and the slider is connected to the nut. The bearing arm is fixed to one side of the slider.

[0017] Furthermore, the second cylinder gripper is fixed to one side of the support arm.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the lifting assembly drives the lead screw to rotate through the motor, and uses the thread transmission relationship between the nut and the lead screw to drive the connected slider to slide in the slide groove of the lifting chamber, so as to realize the smooth lifting of the bearing arm and the second cylinder gripper, so as to apply an upward pulling force to the clothes hanger hook.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] As a common drying tool in daily life, the structural strength of clothes hangers directly affects their service life and practicality. In the clothes hanger manufacturing process, tensile testing is a crucial step in evaluating their durability and deformation performance. In existing technologies, tensile testing of clothes hangers typically involves fixing the hanger with clamping equipment or hooks, then applying tension in the opposite direction and observing the deformation of the hanger under the applied force.

[0028] However, existing clamping devices typically apply force through a single clamping point or hook when fixing clothes hangers. This force is concentrated in a localized area of ​​the hanger, simulating a point load. In actual use, however, the hanger bears a surface load or line load distributed across the entire frame by the weight of the clothing. Due to the difference in force distribution, existing testing methods cannot accurately reflect the deformation characteristics of the hanger under actual drying conditions, leading to discrepancies between test results and actual performance. To address this issue, the inventor has proposed a clothes hanger hook tensile strength testing structure.

[0029] The present invention provides the following preferred embodiments.

[0030] like Figures 1-5 As shown, the tensile strength test structure for clothes hanger hooks includes:

[0031] Base 100:

[0032] The first cylinder gripper 200 is fixed on the base 100, wherein the cylinder gripper includes two grippers that move in opposite directions.

[0033] The limiting clamp includes two sets of limiting components 300 arranged in a mirror symmetrical manner, and the two sets of limiting components 300 are respectively provided on one side of two claws. Each set of limiting components 300 includes a first fang plate 301, a second fang plate 302, and a third fang plate 303, all of which are in the shape of a fang. The first fang plate 301 is fixed to one side of each claw, and the second fang plate 302 slides inside the two sides of the first fang plate 301 respectively.

[0034] Lifting component 400 is mounted on base 100;

[0035] The second cylinder gripper 500 is arranged vertically opposite to the first cylinder gripper 200 and is mounted on the lifting end of the lifting assembly 400.

[0036] By utilizing the displacement of the gripper of the first cylinder 200 in opposite directions, the two first clamping plates 301 are brought together, firmly locking the bottom frame of the hanger into the limiting clamp composed of the first clamping plate 301, the second clamping plate 302, and the third clamping plate 303. Through the sliding structure of the second clamping plate 302 and the third clamping plate 303 inside the first clamping plate 301 on both sides, the contact area with the bottom frame of the hanger can be flexibly adjusted, thereby changing the coverage of the clamping force. This breaks through the limitations of the traditional single clamping point, transforming the point load test into a line load test, and more realistically simulating the stress state of the uniform distribution of the weight of the clothing on the frame of the hanger. It can accurately reflect the deformation of the hanger in actual use, providing more reliable data support for product quality assessment.

[0037] In this embodiment, as Figures 1-5 As shown, the lifting assembly 400 includes a lifting chamber 401, a slide 402, a lead screw 404, a motor 405, a nut 406, a support arm 407, and a slider 403. The lifting chamber 401 is fixed on the base 100. The slide 402 is opened on one side of the lifting chamber 401. The motor 405 is fixed at the bottom inside the lifting chamber 401. One end of the lead screw 404 is fixed on the output shaft of the motor 405, and the other end of the lead screw 404 is rotatably connected to the top inside the lifting chamber 401 through a rotating shaft. The nut 406 is screwed onto the outside of the lead screw 404. The slider 403 slides on the slide 402 of the lifting chamber 401, and the slider 403 is connected to the nut 406. The support arm 407 is fixed on one side of the slider 403. The second cylinder gripper 500 is fixed on one side of the support arm 407.

[0038] The lifting assembly 400 drives the lead screw 404 to rotate via the motor 405. By utilizing the threaded transmission relationship between the nut 406 and the lead screw 404, the slider 403 connected to it slides in the slide groove 402 of the lifting chamber 401, thereby achieving the smooth lifting and lowering of the support arm 407 and the second cylinder gripper 500, so as to apply an upward pulling force to the clothes hanger hook.

[0039] The specific working process of this utility model is as follows:

[0040] First, the bottom edge of the hanger is placed within the limiting clamp formed by the first clamping plate 301, the second clamping plate 302, and the third clamping plate 303. Then, the claw of the first cylinder gripper 200 is moved in opposite directions, causing the two first clamping plates 301 to move closer together, thus firmly locking the bottom edge of the hanger. The motor 405 drives the lead screw 404 to rotate, and the screw 404 is driven by the threaded transmission relationship between the nut 406 and the lead screw 404 to slide the connected slider 403 in the slide groove 402 of the lifting chamber 401, so as to achieve the smooth descent of the bearing arm 407 and the second cylinder gripper 500. At the same time, the claw of the second cylinder gripper 500 is gripped on the hook of the hanger. Then, the motor 405 drives the lead screw 404 to rotate in the opposite direction, so as to smoothly raise the bearing arm 407 and the second cylinder gripper 500, thereby applying an upward pulling force to the hanger hook and completing the tensile strength test.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
