This utility model discloses a quick-change device for a car door gas strut, comprising: a replacement component, which includes an annular block and a retaining strap; and a convenient disassembly component, which includes a connecting groove, a square rod, a retaining groove, a slider, and a push rod. The connecting groove is located on one side of the annular block where it meets the retaining strap. The square rod is fixed to the outer end of the connecting groove. The retaining groove is located on the inner side of the square rod. The slider is slidably connected to the inner side of the retaining groove. The push rod is fixed to one side of the slider and is located inside the connecting groove. This utility model, by setting up the convenient disassembly component, pushes the push rod, which in turn pushes the slider to move within the retaining groove. This causes the push rod to move outward through the slider, pushing the retaining strap outward. The retaining strap then pulls, causing the annular block to move and separating it from the connecting ball, thus separating the gas strut from the connecting ball. This eliminates the need for other tools to disassemble the gas strut, saving disassembly time.

Description

Technical Field

[0001] This utility model relates to the field of automotive door gas strut technology, specifically a quick-change device for automotive door gas struts. Background Technology

[0002] A car door gas strut is a component that uses internal high-pressure gas and a piston rod to provide support, cushioning, and assistance to the car door. It allows the door to maintain a fixed angle after opening, preventing it from falling automatically, and at the same time, it reduces the impact force when closing. The gas strut is quickly engaged with the mating balls on the mounting brackets on both sides of the car body and door through ring blocks at both ends.

[0003] The existing vehicle body and door edges are screwed with mounting brackets. A fixing rod is fixedly connected to one side of the mounting bracket, and a connecting ball is fixedly connected to the fixing rod. The annular blocks at both ends of the gas strut are connected to the connecting balls. The Shudie gas strut is connected to the vehicle body and door. The gas strut can be disassembled by pulling the snap-fit ​​strap on the annular block and pulling the gas strut outward, which facilitates quick replacement of the gas strut. However, the snap-fit ​​strap is tightly attached to the annular block by tension. If the user does not have a suitable tool, it will be impossible to disassemble the gas strut. Therefore, a quick replacement device that is easy to disassemble is needed to facilitate quick disassembly of the gas strut. Utility Model Content

[0033] The easy-to-disassemble component includes a connecting groove 21, a square rod 22, a slot 23, a slider 24, and a push rod 25. The connecting groove 21 is located on one side of the annular block 13 and fits against the snap-fit ​​strap 14. The square rod 22 is fixed to the outer end of the inner side of the connecting groove 21. The slot 23 is located on the inner side of the square rod 22. The slider 24 is slidably connected to the inner side of the slot 23. The push rod 25 is fixed to one side of the slider 24 and is located inside the connecting groove 21.

[0034] The connecting groove 21 is used to connect the square rod 22 and the push rod 25. The square rod 22 is used to open the slot 23. The slot 23 is used to connect and move the slider 24.

The slider 24 drives the push rod 25 to move. The spring 26 unfolds, causing the push rod 25 to drive the push block 27 to push the outer locking band 14. The locking band 14 is pulled up, causing the locking band 14 to drive the annular block 13 to move. This causes the annular block 13 to separate from the docking ball 12, thereby separating the gas strut from the docking ball 12 without the need to use other tools to disassemble the gas strut.

[0040] Please see Figures 1-6 As shown, this embodiment, based on the above embodiment, further includes:

[0041] Limiting components;

[0042] The limiting component includes a limiting hole 31, a limiting rod 32, and an adsorption frame 33; the limiting hole 31 is opened on the surface of the push block 27, the limiting rod 32 is inserted between the limiting hole 31 and the inside of the through hole 28, and the adsorption frame 33 is magnetically attracted to the inner end of the limiting rod 32.

[0043] The limiting hole 31 is used for the insertion of the limiting rod 32. The limiting rod 32 is used to limit the push block 27 and push rod 25 when not in use. The surface of the limiting rod 32 is provided with magnetic force, so that the limiting rod 32 is attracted to the adsorption frame 33 by magnetic force. The adsorption frame 33 is used for the insertion of the inner end of the limiting rod 32.

[0044] One end of the adsorption frame 33 is fixedly connected to the inner edge of the connecting groove 21, and the other end of the limiting rod 32 is fixedly connected to the snap block 34.

[0046] The snap-fit ​​block 34 is used to secure the connection between the limiting rod 32 and the square rod 22, and the pull rod 35 is used to pull the limiting rod 32 so that the limiting rod 32 is separated from the limiting hole 31 and the adsorption frame 33.

[0047] Working principle: When the component is not in use, the push rod 25 and the spring 26 are in use. When the push rod 25 is used, the hand is released, and the spring 26 moves the push rod 25 and the push block 27 to their original positions due to its own elasticity, so that the limiting hole 31 and the adsorption frame 33 are aligned. Hold the limiting rod 32 by hand and insert the limiting rod 32 into the through hole 28, the limiting hole 31 and the adsorption frame 33, so that the limiting rod 32 is attracted to the inside of the through hole 28 and the adsorption frame 33 by magnetic force, causing the limiting rod 32 to drive the locking block 34 to lock with the square rod 22, thereby limiting the push rod 25 and the push block 27 after use and preventing the push rod 25 from shaking due to the elasticity of the spring 26.
