Technical Field

[0001] The utility model relates to the technical field of shock absorber equipment, in particular to a multi-point layered damping shock absorber. Background Technique

[0002] When mechanical equipment (such as stamping equipment) is processing, the equipment will cause relatively large vibrations and high noise to the ground. At present, the commonly used shock absorbers for mechanical equipment on the market mainly include single spring shock absorbers or hydraulic shock absorbers, etc. In the prior art, it is difficult to ensure the stability of mechanical equipment by using the existing single spring shock absorber. At the same time, the single damping force is not enough and cannot provide multi-point damping force.

[0003] For example, a shock absorber disclosed in the authorized patent document with the application number CN201920141590.8 includes a shock absorber body and a suspension ring installed on the shock absorber body. A bushing is installed in the suspension ring. The bushing includes a left bushing and a right bushing for splicing with each other. The left bushing includes a left bushing tube and a left rubber layer coated outside the left bushing tube; the right bushing includes a right bushing tube and a right rubber layer coated outside the right bushing tube; an axial anti-detachment structure is provided between the left bushing tube and the right bushing tube, and a limiting structure for restricting the axial displacement of the suspension ring is provided between the left rubber layer and the right rubber layer and the suspension ring. This utility model has the effects that the bushing and the suspension ring are not easy to detach and the bushing is convenient to install.

[0004] The above patent has a single damping force that is not enough and cannot provide multi-point damping force. Therefore, we need to provide a multi-point layered damping shock absorber. Summary of the Invention

[0005] The purpose of the utility model is to provide a multi-point layered damping shock absorber. When the pressing seat is squeezed, it will descend in the fixed cylinder, and the three springs are compressed. At the same time, the floating disk is pushed to drive the three push rods to swing, so that the three push rods respectively push the three piston rods to move, and the piston block at one end of the piston rod moves in the liquid storage tank. The liquid storage tank is filled with shock-absorbing oil, and the surface of the piston block is in close contact with the inner wall of the liquid storage tank. Thus, the shock-absorbing oil flows through the flow holes on the surface of the piston block to generate a strong damping force.

Springs are clamped inside the three grooves, and the bottoms of the three springs are clamped with a floating disc. The floating disc is slidably installed inside the fixed cylinder, and a damping member is installed at the bottom of the floating disc.

[0011] Preferably, the damping member includes three push rods hinged to the bottom of the floating disc. The lower ends of the three push rods are all hinged with piston rods.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: a multi-point hierarchical damping shock absorber, including:

[0026] Fixed cylinder 1;

[0027] And a pressing seat 2 slidably installed on the top of the fixed cylinder 1;

[0028] A shock absorber 3 provided inside the fixed cylinder 1 for multi-layer buffering;

[0029] The shock absorber 3 includes three groove bodies 31 opened at the bottom of the pressing seat 2. Springs 32 are clamped inside the three groove bodies 31, and the bottoms of the three springs 32 are clamped with a floating disc 33. The floating disc 33 is slidably installed inside the fixed cylinder 1, and a damping member 30 is installed at the bottom of the floating disc 33.

[0030] The damping member 30 includes three push rods 301 hinged to the bottom of the floating disc 33. The lower ends of the three push rods 301 are all hinged with piston rods 302. A ring body 303 is fixedly installed on the surface of the fixed cylinder 1. The opposite ends of the three piston rods 302 all penetrate through the ring body 303 and are installed with piston blocks 304. Three liquid storage tanks 305 are opened inside the ring body 303. The three piston blocks 304 are respectively installed in the three liquid storage tanks 305, and flow holes 306 are opened on the surfaces of the three piston blocks 304;

[0031] In this embodiment, when the pressing seat 2 is extruded, it will descend within the fixed cylinder 1, and the three springs 32 are compressed. At the same time, the floating disc 33 is pushed to drive the three push rods 301 to swing, so that the three push rods 301 respectively push the three piston rods 302 to move, causing the piston block 304 at one end of the piston rod 302 to move within the liquid storage tank 305. The liquid storage tank 305 is filled with damping oil, and the surface of the piston block 304 is in close contact with the inner wall of the liquid storage tank 305. Thus, the damping oil flows through the flow holes 306 on the surface of the piston block 304, generating a strong damping force. At the same time, the rubber layer ring 6 provided between the floating disc 33 and the pressing seat 2 also provides a damping effect, achieving multi-point hierarchical damping.

[0032] The surface of the piston block 304 is in close contact with the inner wall of the liquid storage tank 305, and a sealing ring 4 is provided on one side of each of the three liquid storage tanks 305;

[0033] Specifically, the surface of the piston rod 302 is in close contact with the inside of the sealing ring 4, playing a role in sealing and protecting the inside of the liquid storage tank 305.

[0034] Three mounting slots 5 are provided inside the ring body 303;

[0035] Setting three mounting slots 5 facilitates the installation of the ring body 303.

[0036] A rubber layer ring 6 is fixedly installed at the top of the floating disc 33, and the top of the rubber layer ring 6 is in contact with the bottom of the pressing seat 2;

[0037] Among them, the rubber layer ring 6 provided between the floating disc 33 and the pressing seat 2 also provides a damping effect.

[0038] Three insertion rods 7 are fixedly installed at the bottom of the floating disc 33, and sockets 8 are slidably installed at the bottoms of the three insertion rods 7. The bottoms of the three sockets 8 are fixedly installed on the bottom inner wall of the fixed cylinder 1;

[0039] It should be noted that the movement of the floating disc 33 will drive the insertion rods 7 to slide within the sockets 8, providing guidance for the movement of the floating disc 33.

[0040] A dust-proof sleeve 9 is fixedly installed at the top of the fixed cylinder 1, and the inner wall of the dust-proof sleeve 9 is in contact with the surface of the pressing seat 2;

[0041] Specifically, during the movement of the pressing seat 2, the dust-proof sleeve 9 can scrape off the dust on the surface of the pressing seat 2.

[0042] When the pressing seat 2 of this device is squeezed, it will descend within the fixed cylinder 1, the three springs 32 are compressed, and at the same time, the floating disk 33 is pushed to drive the three push rods 301 to swing, so that the three push rods 301 respectively push the three piston rods 302 to move, making the piston block 304 at one end of the piston rod 302 move within the liquid storage tank 305. The liquid storage tank 305 is filled with damping oil, and the surface of the piston block 304 is in close contact with the inner wall of the liquid storage tank 305, so that the damping oil circulates through the circulation holes 306 on the surface of the piston block 304, generating a strong damping force. At the same time, the rubber layer ring 6 provided between the floating disk 33 and the pressing seat 2 also provides a damping effect, realizing multi-point hierarchical damping.

The scope of the present invention is defined by the appended claims and their equivalents.
