Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a quick assembly and disassembly device for gas springs. Background Technology

[0002] A gas spring is a closed pressure cylinder filled with inert gas or an oil-gas mixture, creating a pressure several times or tens of times higher than atmospheric pressure. The piston rod moves due to the pressure difference generated by the smaller cross-sectional area of ​​the piston rod compared to the piston's cross-sectional area. It consists of the following parts: a pressure cylinder, piston rod, piston, sealing guide sleeve, filling material (inert gas or an oil-gas mixture), internal and external control elements (referring to the controllable gas spring), and connectors.

[0003] In existing technology, when replacing gas springs in automobiles, the lack of support from the gas springs after removal causes the car suspension, which is supported by the gas springs, to tilt downwards, making reassembly difficult. In addition, the limited space at the car suspension makes the operation even more inconvenient for workers. To address these issues, we propose a quick gas spring removal and installation device. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a quick assembly and disassembly device for gas springs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-release device for a gas spring includes a connecting frame, on which a disassembly and assembly component is provided, and on which an operating lever is provided;

[0007] The assembly / disassembly assembly includes a slide rotatably connected to the connecting frame, a retaining sleeve fixedly connected to the slide, a support plate slidably connected to the connecting frame, a slider fixedly connected to the support plate and slidably connected to the connecting frame, a threaded rod rotatably connected to the connecting frame, a symmetrically arranged rotating rod rotatably connected to the end of the threaded rod near the slider and rotatably connected to the slider, a drive sleeve slidably connected to the threaded rod away from the rotating rod, a drive rod rotatably connected inside the operating lever, and the drive rod and drive sleeve connected by a universal coupling.

[0008] Preferably, a sleeve is fixedly connected to the drive rod, a sleeve is held in the sleeve, a pull rope is slidably connected in the sleeve, one end of the pull rope near the connecting frame is fixedly connected to the slide, and a guide wheel is rotatably connected to the connecting frame, with the guide wheel abutting against the pull rope.

[0009] Preferably, the connecting frame is provided with a spherical sleeve, and a connecting sleeve is rotatably connected inside the spherical sleeve. The connecting sleeve is fixedly connected to the operating rod, and the universal coupling is located inside the spherical sleeve.

[0010] Preferably, a handwheel is fixedly connected to the end of the drive rod away from the universal coupling, and an extension rod is slidably connected to the handwheel.

[0011] Preferably, a connecting block is rotatably connected to one end of the threaded rod near the rotating rod, and the rotating rod is rotatably connected to the connecting block.

[0012] Preferably, a pull ring is fixedly connected to the end of the pull rope away from the slide.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting up a disassembly and assembly component, allows the user to rotate the operating lever after the slide is clipped onto the gas spring, thereby causing the drive sleeve to rotate, which in turn causes the threaded rod to rotate. At this time, the threaded rod, in conjunction with the rotating rod, drives the drive sleeve to move, using the support plate to lift the car suspension, thereby increasing the distance between the car suspension and the car shock absorber. Then, the slide is rotated to remove the gas spring, and after placing the new gas spring on the slide, the slide is rotated again to move the new gas spring to the installation position. Finally, the user tightens the fasteners to complete the entire gas spring disassembly and assembly operation.

[0015] 2. In this utility model, by setting a jacket and sleeve, the user can drive the slide to rotate by pulling the rope without manually moving the slide, which further facilitates the user's disassembly and assembly of the gas spring. By setting a handwheel and extension rod, the handwheel can be easily rotated by the user to drive the drive rod. When a large torque is required, the user can slide the extension rod away from the center of the handwheel and then drive the drive rod to rotate by rotating the extension rod.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A quick assembly / disassembly device for a gas spring includes a connecting frame 1, on which a disassembly / disassembly assembly is provided, and on which an operating lever 2 is provided.

[0022] The assembly / disassembly assembly includes a slide 3 rotatably connected to the connecting frame 1, a retaining sleeve 4 fixedly connected to the slide 3, a support plate 5 slidably connected to the connecting frame 1, a slider 6 fixedly connected to the support plate 5, and the slider 6 slidably connected to the connecting frame 1. A threaded rod 7 is rotatably connected to the connecting frame 1. A symmetrically arranged rotating rod 8 is rotatably connected to one end of the threaded rod 7 near the slider 6, and the rotating rod 8 is rotatably connected to the slider 6. A drive sleeve 9 is slidably connected to the threaded rod 7 away from the rotating rod 8. The drive sleeve 9 can drive the threaded rod 7 to rotate, or slide towards or away from the threaded rod 7. A drive rod 11 is rotatably connected inside the operating rod 2, and the drive rod 11 and the drive sleeve 9 are connected by a universal coupling 10.

[0023] In this design, when the user is assembling or disassembling the gas spring, the user can clamp the sleeve 4 and the support plate 5 onto the upper and lower ends of the gas spring. Then, the user rotates the drive rod 11, which, in conjunction with the universal coupling 10, drives the drive sleeve 9 to rotate. After the drive sleeve 9 rotates, it drives the threaded rod 7 to rotate. At this time, the threaded rod 7 moves closer to the gas spring and causes the two rotating rods 8 to rotate vertically. At this time, the distance between the two sliders 6 increases, which in turn increases the distance between the support plate 5 and the car's suspension and shock absorber. At the same time, the user can remove the fasteners from the gas spring and the car's suspension and shock absorber. Finally, by rotating the slide 3, the gas spring can be removed.

[0024] The user then rotates the slide 3 to remove the gas spring from the slide 3, and then reinstalls the new gas spring or repairs the original gas spring onto the slide 3. After that, the user rotates the slide 3 to move the gas spring to its original installation position, and then tightens the fasteners to complete the reinstallation of the gas spring. Finally, the user rotates the drive rod 11 again to move the threaded rod 7 away from the gas spring, so that the support plate 5 moves closer to each other until the support plate 5 no longer supports the car suspension. In this way, the user can remove this disassembly and assembly device.

[0025] It should be noted that, since different cars have different chassis and suspension heights, and users need to operate on the side of the car closest to the gas spring when disassembling the gas spring in different positions, a universal coupling 10 is set to connect the drive rod 11 and the drive sleeve 9, making it more convenient for users to operate without having to stay under the car chassis for a long time, which greatly facilitates the user's disassembly and installation work.

[0026] Furthermore, a sleeve 12 is fixedly connected to the drive rod 11, a sleeve 13 is held in the sleeve 12, a pull rope 14 is slidably connected in the sleeve 13, one end of the pull rope 14 near the connecting frame 1 is fixedly connected to the slide 3, and a guide wheel 15 is rotatably connected to the connecting frame 1, and the guide wheel 15 is abutted against the pull rope 14.

[0027] In this design, multiple clips 12 are provided to fix the sleeve 13, and two sleeves 13 and pull ropes 14 are provided to drive the slide 3 to rotate in different directions. The guide wheel 15 is used to cooperate with the pull rope 14 to guide the rotation direction of the slide 3, so that the user does not need to manually rotate the slide 3 under the car chassis, but can rotate the slide 3 to a position that is convenient for the user to remove or place the gas spring.

[0028] Furthermore, the connecting frame 1 is provided with a spherical sleeve 16, and a connecting sleeve 17 is rotatably connected inside the spherical sleeve 16. The connecting sleeve 17 is fixedly connected to the operating rod 2, and the universal coupling 10 is located inside the spherical sleeve 16.

[0029] In this design, the universal coupling 10 is placed inside the connecting sleeve 17, which can protect the universal coupling 10 without hindering the rotation control lever. At the same time, the operating lever 2 is mainly provided to facilitate the operation of rotating the drive lever 11 by holding the operating lever 2.

[0030] Furthermore, a handwheel 18 is fixedly connected to one end of the drive rod 11 away from the universal coupling 10, and an extension rod 19 is slidably connected to the handwheel 18;

[0031] In this design, a handwheel 18 is provided to facilitate the user's rotation of the drive rod 11, while the extension rod 19 is used to amplify the torque and assist the user in operation when the support plate 5 is under stress and the user has difficulty rotating the drive rod 11.

[0032] Furthermore, a connecting block 20 is rotatably connected to one end of the threaded rod 7 near the rotating rod 8, and the rotating rod 8 is rotatably connected to the connecting block 20;

[0033] In this design, the connecting block 20 is mainly used to facilitate the user to replace the threaded rod 7 after the thread has been damaged by repeated use.

[0034] Furthermore, a pull ring 21 is fixedly connected to the end of the pull rope 14 away from the slide 3. The pull ring 21 makes it convenient for the user to pull the pull rope 14 and control the position of the slide 3.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
