Description

Technical Field

[0001] This utility model relates to the field of clothes hanger testing technology, specifically a plastic clothes hanger drop impact testing device. Background Technology

[0002] In daily life, clothes hangers, as a common household item, inevitably fall from a certain height to the ground due to human error or accidents, colliding with the ground. Since clothes hangers are usually made of materials such as plastic, their impact resistance directly affects the product's durability and lifespan.

[0003] However, interior design styles and flooring materials vary significantly across different homes, including cement, tile, wood, and metal floors. These different hardnesses and materials result in varying impact effects when a clothes hanger is dropped, leading to significant differences in the degree of damage. Therefore, testing the impact resistance of clothes hangers requires not only considering the single variable of drop height but also simulating the damage caused by drops on different flooring materials to more comprehensively assess their actual performance. However, existing testing devices lack simulation capabilities for floor structures with varying hardness, failing to accurately reflect the differences in damage caused by drops on different material surfaces, thus limiting the limitations of the measurement structure. Utility Model Content

[0004] This invention addresses the technical problems existing in the prior art by providing a plastic clothes hanger drop impact testing device. This solves the problem that existing testing devices lack simulation of ground structures with different hardness, cannot accurately reflect the differences in damage to clothes hangers when dropped on different material surfaces, and thus have certain limitations in the measurement structure.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a plastic clothes hanger drop impact testing device, comprising:

[0006] Base;

[0007] A lifting assembly, wherein the lifting assembly is disposed on the top of the base;

[0008] A turntable, which is rotatably connected to a base via a rotating shaft;

[0009] A variety of ground structures with different hardnesses are arranged in a circular array on a turntable;

[0010] A suspension tube for hanging clothes hangers, the suspension tube being disposed on the lifting end of the lifting assembly;

[0011] A pushing assembly is disposed on the lifting end of the lifting assembly, and the pushing assembly is displaced along the axial direction of the suspension tube to push the clothes hanger suspended on the suspension tube down onto one of the ground structures.

[0012] The beneficial effects of this utility model are:

[0013] 1) This testing device features various floor structures of different hardness on a turntable, allowing for flexible switching between them via the turntable's rotation. During testing, the hanger to be tested is suspended from the suspension tube. When testing the drop impact effect on a specific floor structure, the turntable can be rotated to adjust the floor structure to the hanger's drop position. The pusher component then pushes the hanger onto the target test floor structure to complete the test. This device comprehensively simulates the impact scenarios that hangers may encounter on different floor materials in a real home environment. Compared to the limitations of existing technologies that only adjust the drop impact height, this device significantly improves the matching degree between the test conditions and the real-world usage environment, making the test results more representative and valuable for reference.

[0014] 2) In summary, this device effectively solves the problems of limited scenarios and insufficient realism in the existing technology of clothes hanger drop impact testing by introducing various ground structures with different hardness, adjustable height lifting components, and automated material pushing components.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] Furthermore, the lifting assembly includes a column, a motor, a worm gear, a worm shaft, a gear, a rack, and a sliding plate in the shape of a U-shape. One end of the column is fixed to the base, and the rack is fixed to one side of the column.

[0017] Furthermore, the slide plate is fitted outside the column, the motor is fixed to one side of the slide plate, and the two sides of the gear are rotatably connected to the inside of the slide plate through a rotating shaft, and the gear meshes with the rack.

[0018] Furthermore, one end of the worm is fixed to the motor output shaft, the worm wheel meshes with one side of the worm, and one side of the worm wheel is coaxially connected to the gear through a sliding plate.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the motor drives the worm to rotate, and the worm gear meshes to transmit the rotation to the gear. Then, the meshing of the gear and rack converts the rotational motion into the linear lifting and lowering motion of the slide along the column, thereby adjusting the horizontal height of the suspension tube and the clothes hanger hanging on the suspension tube, so as to conduct drop impact tests on the clothes hanger at different horizontal heights.

[0020] Furthermore, the pushing assembly includes an electric push rod, a connecting rod, and a bushing, with the electric push rod fixed to one side of the slide plate.

[0021] Furthermore, the bushing is fitted onto the outside of the suspension tube, and the connecting rod is fixed between the drive end of the electric push rod machine and the bushing.

[0022] The beneficial effect of adopting the above-mentioned further solution is that by displacing the drive end of the electric push rod machine along the axial direction of the suspension tube, and by displacing it along the axial direction of the suspension tube outside the suspension tube through the linkage shaft sleeve, the clothes hanger hanging outside the suspension tube can be pushed down from one end of the suspension tube to one of the ground structures.

[0023] Furthermore, the various types of floor structures include cement floors, tile floors, wood flooring floors, and metal floors.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the turntable is distributed with cement floor, tile floor, wooden floor and metal floor, which represent common floor types in daily life. For example, cement floor simulates the outdoors, tile floor simulates a family bathroom or kitchen, wooden floor simulates the wooden floor of a bedroom or living room, and metal floor may correspond to certain special scenarios (such as factory workshop or elevator). By rotating the turntable, different floor structures can be selected to be placed under the position where the clothes hanger falls. Users only need to rotate the turntable to switch the test floor, without having to frequently change the test platform or manually adjust the floor material. Compared with traditional single floor test equipment, this design significantly reduces preparation time and improves test efficiency, and is especially suitable for batch testing or multi-condition comparison tests.

[0030] 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.

[0031] In daily life, clothes hangers, as a common household item, inevitably fall from a certain height to the ground due to human error or accidents, colliding with the ground. Since clothes hangers are usually made of materials such as plastic, their impact resistance directly affects the product's durability and lifespan.

[0032] However, interior decoration styles and flooring materials vary significantly among different households, such as cement floors, tile floors, wood floors, or metal floors. These different hardnesses and materials result in varying impact effects when a clothes hanger is dropped, leading to significant differences in the degree of damage. Therefore, testing the impact resistance of clothes hangers requires not only considering the single variable of drop height but also fully simulating the damage caused by drops on different flooring materials to more comprehensively evaluate their actual performance. However, existing testing devices lack simulation of floor structures with different hardnesses and cannot accurately reflect the differences in damage caused by clothes hangers dropping on different material surfaces, resulting in certain limitations in the measurement structure. To address these issues, the inventor has proposed a plastic clothes hanger drop impact testing device.

[0033] The present invention provides the following preferred embodiments.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the plastic hanger drop impact testing device includes:

[0035] Base 100;

[0036] A lifting assembly 200 is disposed on the top of the base 100;

[0037] Turntable 900, which is rotatably connected to base 100 via a rotating shaft;

[0038] Multiple ground structures with different hardness are arranged in a ring array on the turntable 900.

[0039] A suspension tube 300 for hanging clothes hangers is provided on the lifting end of the lifting assembly 200;

[0040] A pushing component 400 is disposed on the lifting end of the lifting component 200, and the pushing component 400 is displaced along the axial direction of the suspension pipe 300 to push the clothes hanger suspended on the suspension pipe 300 down onto one of the ground structures.

[0041] This testing device features various floor structures of different hardness on a turntable 900, and allows for flexible switching between these structures by rotating the turntable 900. During testing, the hanger to be tested is suspended from the suspension tube 300. When testing the drop impact effect on a specific floor structure, the turntable 900 can be rotated to adjust the floor structure to the hanger's drop position. Then, the pusher assembly 400 pushes the hanger onto the target test floor structure to complete the test. This device comprehensively simulates the impact scenarios that hangers may encounter on different floor materials in a real home environment. Compared to the limitations of existing technologies that only adjust the drop impact height, this device significantly improves the matching degree between the test conditions and the real-world usage environment, making the test results more representative and valuable for reference.

[0042] In summary, this device effectively solves the problems of limited scenarios and insufficient realism in existing technologies for clothes hanger drop impact tests by introducing various ground structures with different hardness, an adjustable height lifting component 200, and an automated material pushing component 400.

[0043] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the lifting assembly 200 includes a column 201, a motor 207, a worm gear 202, a worm 203, a gear 204, a rack 205, and a sliding plate 206 in the shape of a U-shape. One end of the column 201 is fixed to the base 100. The rack 205 is fixed to one side of the column 201. The sliding plate 206 is sleeved on the outside of the column 201. The motor 207 is fixed to one side of the sliding plate 206. The two sides of the gear 204 are rotatably connected to the inside of the sliding plate 206 through a rotating shaft, and the gear 204 meshes with the rack 205. One end of the worm 203 is fixed to the output shaft of the motor 207. The worm gear 202 meshes with one side of the worm 203, and one side of the worm gear 202 is coaxially connected to the gear 204 through the sliding plate 206.

[0044] The motor 207 drives the worm 203 to rotate, and the worm gear 202 and worm 203 mesh to the gear 204 to rotate. The meshing of the gear 204 and the rack 205 converts the rotational motion into the linear lifting and lowering motion of the slide plate 206 along the column 201. This allows the horizontal height of the suspension tube 300 and the clothes hanger suspended on the suspension tube 300 to conduct drop impact tests on the clothes hanger at different horizontal heights.

[0045] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the pusher assembly 400 includes an electric pusher 401, a connecting rod 402, and a bushing 403. The electric pusher 401 is fixed to one side of the slide plate 206, the bushing 403 is sleeved on the outside of the suspension tube 300, and the connecting rod 402 is fixed between the drive end of the electric pusher 401 and the bushing 403.

[0046] The electric push rod 401 moves along the axial direction of the suspension tube 300 through the drive end, and through the linkage shaft sleeve 403 of the connecting rod 402, it also moves along the axial direction of the suspension tube 300 outside the suspension tube 300. In this way, the clothes hanger hanging outside the suspension tube 300 can be pushed down from one end of the suspension tube 300 onto one of the ground structures.

[0047] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the various floor structures include a cement floor 500, a tile floor 600, a wooden floor 700, and a metal floor 800. The turntable 900 is equipped with these floor structures, representing common floor types found in daily life. For example, the cement floor 500 simulates the outdoors, the tile floor 600 simulates a bathroom or kitchen, the wooden floor 700 simulates a wooden floor in a bedroom or living room, and the metal floor 800 may correspond to certain special scenarios (such as a factory workshop or elevator). By rotating the turntable 900, different floor structures can be selected to be placed below the clothes hanger's drop position. Users can switch test floors simply by rotating the turntable 900, eliminating the need for frequent changes to the test platform or manual adjustment of the floor material. Compared to traditional single-floor testing equipment, this design significantly reduces preparation time and improves testing efficiency, making it particularly suitable for batch testing or multi-condition comparison experiments.

[0048] The specific working process of this utility model is as follows:

[0049] (1) Preparation before feeding

[0050] First, hang the plastic hanger to be tested on the outside of the suspension tube 300 using hooks.

[0051] (2) Raise the plastic clothes hanger

[0052] The motor 207 drives the worm 203 to rotate, and the worm gear 203 is driven to rotate the gear 204 through the meshing of the worm wheel 202. The rotational motion is then converted into the linear lifting and lowering motion of the slide plate 206 along the column 201 by the meshing of the gear 204 and the rack 205, thereby adjusting the horizontal height of the suspension pipe 300 and the clothes rack hanging on the suspension pipe 300.

[0053] (3) Select the ground structure where the plastic clothes hanger will fall.

[0054] For example, if you select cement floor 500, by rotating turntable 900, the cement floor 500 on turntable 900 will rotate to a position below one end of suspension pipe 300.

[0055] (4) Conduct drop impact test

[0056] The electric push rod 401 moves along the axial direction of the suspension tube 300 through the drive end, and through the linkage shaft sleeve 403 of the connecting rod 402, it also moves along the axial direction of the suspension tube 300 outside the suspension tube 300, pushing the clothes hanger hanging outside the suspension tube 300 from one end of the suspension tube 300 onto the cement ground 500.

[0057] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
