Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of novel buffers, and more specifically, particularly relates to a novel buffer with optimized buffering stability effect. Background Art
[0002] With the development of science and technology, the design of buffers has become more precise and efficient. However, the existing buffers are all single piston rods. When the piston rod is pushing at high speed, the single piston rod is prone to displacement in the cavity or breakage due to excessive pressure. Displacement and breakage will cause irreversible damage to the shock absorbing equipment. In addition, due to the high cost and complex process of some current buffers, if damaged, they can only be replaced as a whole.
[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a new type of buffer with optimized buffering and stabilizing effect is provided, in order to achieve a purpose with greater practical value. Utility Model Content
[0004] The utility model provides a novel buffer with optimized buffering stabilization effect, which is used to overcome the above-mentioned defects in the prior art.
[0005] The purpose and effect of the new type of buffer for optimizing the buffering stability effect of the utility model are achieved by the following specific technical means:
[0006] The cam is configured to move the spring between the first and second sliding positions, the second end of the spring being configured to move the spring between the first and second sliding positions, the second end of the spring being configured to move the spring between the second and second sliding positions, and the third end of the spring being configured to move the spring between the second and second sliding positions.
[0007] According to a further technical solution, a silencer cap is fixedly connected to the upper part of the impact head.
[0008] According to a further technical solution, a buffer block is fixedly installed below the first sliding cavity and the second sliding cavity.
[0009] According to a further technical solution, the No. 2 spring and the No. 3 spring are welded and fixed to the upper end of the buffer block.
[0010] According to a further technical solution, a through hole connecting the movable cavity and the third sliding cavity is provided in the middle of the fixed clamping plate.
[0011] According to a further technical solution, a thread groove is provided on the surface of the outer cylinder.
[0012] According to a further technical solution, a pressure relief hole penetrating to the outside is provided at the bottom of the third sliding cavity.
[0013] A further technical solution is to provide an oil seal above the oil storage foam.
[0014] According to a further technical solution, a dust ring is fixedly installed above the oil seal block.
[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] The sliding guide rod is fixed on the piston rod. The function of the sliding guide rod is to provide guidance and reduce support for the piston rod. When the buffer is subjected to high-speed external force, the first spring inside the piston rod buffer applies compression force, which can easily cause the buffer to deform. The sliding guide rod guides and limits the movement direction of the piston rod, allowing it to slide relatively along the designed trajectory. The second and third springs can also reduce the effect of the compression force and ensure the service life of the buffer.
[0017] The pressure relief hole provided on the pressure-resistant bottom plate of the utility model can enable the buffer to help maintain the stability of the piston rod. When the moving object is subjected to external high-speed impact, the pressure relief hole can balance the internal and external pressure differences, prevent the buffer from failing or being damaged due to pressure imbalance and increase its service life.
[0018] A silencer cap is provided on the upper part of the impact head to reduce the pressure and vibration inside the buffer and effectively reduce the vibration generated when the piston rod is working. When the impact head is subjected to external impact, the silencer cap can play a role in buffering and shock absorption to protect the buffer from damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Preferably, see Attachment Figure 4 A dust ring 12 is fixedly installed above the oil seal block 14.
[0039] Specific usage of this utility model:
[0040] When using the utility model, first, the utility model is fixedly installed in a specific position. When a heavy object pushes the silencer cap 1 at the front end of the buffer, the piston rod 2 at the lower end of the impact head 15 will drive the touch-pressure base plate 10 to exert pressure on the No. 1 spring 11 inside the third sliding cavity 104. The No. 1 spring 11 will rebound against the pressure, and the touch-pressure base plate 10 will generate pressurized gas when pushing inside the third sliding cavity 104. The pressurized gas will be discharged to the outside through the pressure relief hole 5, and the sliding guide rod 8 welded and installed on the surface of the piston rod 2 will push the No. 2 spring 6 and the No. 3 spring 18 inside the first sliding cavity 101 and the second sliding cavity 103 through the fixed slider 17. The piston rod 2 can slide stably inside the third sliding cavity 104, and the piston rod 2 will not be deformed or displaced during high-speed extrusion due to the momentary heavy pressure. The oil storage foam 13 arranged in the third sliding cavity 104 can lubricate the surface of the piston rod 2. When the oil storage foam 13 is subjected to rapid friction and extrusion, in order to prevent a large amount of hydraulic oil from being generated on the oil surface and being carried out at high speed, the oil seal 14 arranged above the oil storage foam 13 will absorb the oil surface. The touch-pressure base plate 10 arranged at the bottom of the third sliding cavity 104 and the buffer blocks 7 inside the first sliding cavity 101 and the second sliding cavity 103 can release external force, so that the buffer can work more smoothly and improve its service life.
