Description

Technical Field

[0001] This utility model relates to the field of spring shock absorber technology, and in particular to a spring shock absorber with high stability. Background Technology

[0002] A spring damper is an elastic support element that absorbs and buffers external energy through the deformation of its elastic element. Widely used in various fields, it is specifically designed to reduce or eliminate vibrations and shocks caused by operational or external influences (such as periodic vibrations or instantaneous impacts caused by wind, steam hammer, and earthquakes). It achieves this function through damping, initial force stiffness, and spring pre-compression. When subjected to vibration or impact, the spring deforms and stores elastic potential energy, thereby reducing the impact of the vibration or impact on the supported object or system. Once the external vibration or impact stops acting on the spring damper, the spring releases the stored elastic potential energy, and the impact generated during the spring's recovery process is further reduced by the buffer and damping materials.

[0003] Currently, the spring shock absorbers widely used in the market are relatively complicated to disassemble and install because the spring and piston rod are tightly connected. This not only increases the labor intensity and operation difficulty, but may also affect maintenance efficiency. In addition, the shock absorption effect of the spring shock absorbers is fixed and the shock absorption intensity cannot be adjusted according to the needs, so their practicality needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a spring shock absorber with high stability, which allows for quick removal and replacement of the spring, is easy to disassemble and assemble, improves maintenance efficiency, and allows for free adjustment of the shock absorber's damping intensity, greatly improving the practicality of the shock absorber.

[0005] To achieve the above objectives, a highly stable spring shock absorber is provided, comprising a piston cylinder, a piston rod being damped and slidably mounted inside the piston cylinder, a connecting seat being fixedly connected to the bottom of the piston cylinder and the top of the piston rod, a spring being installed between the two connecting seats, a limit adjustment component for limiting the spring being slidably limited on each connecting seat, and threaded grooves being opened on the opposite sides of the two connecting seats, with a limit cover for limiting the limit adjustment component being threadedly connected in each threaded groove;

[0006] The limiting adjustment assembly includes a limiting ring, with two limiting rings arranged symmetrically in an upper and lower configuration. A cylinder is symmetrically fixed to the upper surface of the bottom limiting ring. A blocking block is slidably connected to the inner wall of the cylinder. A screw is fixed to the top of the blocking block. A through hole corresponding to the position of the screw is opened at the bottom of the top limiting ring. A nut for limiting the top limiting ring is threaded onto the outer wall of the screw.

[0007] According to the aforementioned high-stability spring damper, each of the two limiting rings has a limiting groove on its opposite surface, and both ends of the spring are located within the limiting groove.

[0008] According to the aforementioned high-stability spring shock absorber, the side walls of the connecting seats are provided with limiting blocks, the inner side walls of the limiting rings are provided with limiting grooves that are adapted to the limiting blocks, and the opposite ends of the two connecting seats are provided with retaining rings.

[0009] According to the aforementioned high-stability spring shock absorber, there are four nuts, with the upper and lower nuts forming a group, and the upper limiting ring located in the middle of each group of nuts.

[0010] According to the aforementioned high-stability spring damper, the sidewalls of the screw are all slidably connected to the through holes.

[0011] According to the aforementioned high-stability spring shock absorber, each of the limiting covers is provided with a rotating handle.

[0012] According to the aforementioned high-stability spring shock absorber, the limiting cover covers the limiting block.

[0013] According to the aforementioned high-stability spring damper, a connecting ring is provided on the opposite sides of both connecting seats.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with the existing technology, the spring needs to be disassembled and replaced by setting a connecting seat, limit adjustment component and limit cover. First, remove the nut on the top. Next, rotate the limit cover to disengage it from the threaded groove, which can release the limit ring and spring. Slide the limit ring off the connecting seat to remove the spring for replacement. Disassembly and assembly are convenient and maintenance efficiency is improved.

[0016] 2. Compared with existing technologies, the design incorporates a cylinder, plug, screw, and nut. During the extension and retraction of the shock absorber, the screw slides within the cylinder, further enhancing the shock absorber's stability. When adjusting the shock absorber's strength as needed, first adjust the lower nut downwards. Next, simultaneously rotate the upper nut to adjust the top limit position of the limiting ring, thereby adjusting the piston rod's extension length and the spring's compression force. Then, rotate the lower nut to adjust the lower limit position of the limiting ring. This allows for free adjustment of the shock absorber's damping strength, greatly improving its practicality.
