Abstract
The utility model discloses a hydraulic buffer for removing a noise source. The hydraulic buffer comprises a cylinder barrel, damping oil arranged in the cylinder barrel, a piston, a piston rod and a guide sleeve. The hydraulic buffer is characterized by also comprising a sealing ring and a spring, wherein the tail part of the spring pushes against the guide sleeve, and the front end of the spring pushes against the sealing ring; and the sealing ring moves back and forth with the movement of the piston rod. The floating sealing ring and the spring are arranged in the hydraulic buffer, and the volume change of a cavity between the piston rod and the cylinder barrel due to the movement of the piston rod is adapted by the displacement of the sealing ring and the deformation of the spring, so that the noise trouble caused by using sponge is avoided. The hydraulic buffer for removing the noise source disclosed by the utility model is of significant advance in hydraulic buffer technology.
Description
Technical field
The utility model relates to the hydraulic bjuffer technical field, is specifically related to a kind of hydraulic bjuffer of the source that abates the noise.
Background technique
Hydraulic bjuffer is a kind of through external shock power being converted to the hydraulic pressure ability; Can convert the device of other form of energy again to by hydraulic pressure; Compare with the buffering device of other form such as spring, PU glue, air erasable storage, damper; Hydraulic bjuffer is the mildest buffering device device, is widely used in industry, every field such as civilian.
As shown in Figure 1, the hydraulic bjuffer of existing technology comprises cylinder barrel 2, is positioned at the damping oil 1 of cylinder barrel 2, piston 3, piston rod 4, sponge 5, seal ring 6 and guide sleeve 7.Seal ring 6 is fixed on the front end of guide sleeve 7.Sponge 5 is filled up the cavity space between piston rod 4 and the cylinder barrel 2 through compression and expansion, owing to contain air bubble in the sponge, when sponge 5 was compressed, air bubble can break owing to squeezing action, and produced noise.The hydraulic bjuffer of existing technology is demanded urgently improving.
The model utility content
The technical problem that the utility model will solve provides a kind of hydraulic bjuffer of the source that abates the noise, and the hydraulic bjuffer that overcomes existing technology is when sponge is compressed, and air bubble can break and produce the defective of noise.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be:
A kind of hydraulic bjuffer of the source that abates the noise; Comprise cylinder barrel, be positioned at damping oil, piston, piston rod and the guide sleeve of cylinder barrel; Also comprise seal ring and spring; The tail end of the said spring said guide sleeve of conflicting, its front end said seal ring of conflicting, said seal ring moves forward and backward with moving of said piston rod.
The hydraulic bjuffer in the described source that abates the noise wherein also comprises support ring, the conflict front end of said spring of the bottom surface of said support ring, the end face of the said support ring said seal ring of conflicting.
The hydraulic bjuffer in the described source that abates the noise, the bottom surface of wherein said support ring is fixedly connected with the front end of said spring.
The hydraulic bjuffer in the described source that abates the noise, the tail end of wherein said spring is fixedly connected with said guide sleeve.
The beneficial effect of the utility model: the utility model is provided with unsteady seal ring and spring in hydraulic bjuffer; The displacement through seal ring and the distortion of spring adapt to piston rod and the cavity volume between the cylinder barrel that the motion because of piston rod brings and change; So just avoided the noise puzzlement because of using sponge to bring, the utility model is the major progress of hydraulic bjuffer technology.
Description of drawings
The utility model comprises following accompanying drawing:
Fig. 1 is an existing technology hydraulic bjuffer schematic representation;
Fig. 2 is the utility model hydraulic bjuffer schematic representation.
Embodiment
According to accompanying drawing and embodiment the utility model is done further explain below:
As shown in Figure 2; The abate the noise hydraulic bjuffer in source of the utility model; Comprise cylinder barrel 22, be positioned at damping oil 11, piston 33, piston rod 44 and the guide sleeve 88 of cylinder barrel, also comprise seal ring 55 and spring 77, the tail end conflict guide sleeve 88 of spring 77; Its front end conflict seal ring 55, seal ring 55 moves forward and backward with moving of piston rod 44.Also comprise support ring 66, the front end of the bottom surface conflict spring 77 of support ring 66, the end face conflict seal ring 55 of support ring 66.
The bottom surface that the further optimization of the utility model is support ring 66 is fixedly connected with the front end of spring 77.The tail end of spring 77 is fixedly connected with guide sleeve 88.
Those skilled in the art do not break away from the essence and the spirit of the utility model; Can there be the various deformation scheme to realize the utility model; The above is merely the preferable feasible embodiment of the utility model; The interest field that is not so limits to the utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all is contained within the interest field of the utility model.
