Abstract

The invention discloses a noise reduction cylinder. The noise reduction cylinder comprises a cylinder body, a cylinder cover and a piston; a square groove is formed inside the cylinder cover; a rubber gasket is arranged between the cylinder body and the cylinder cover; the cylinder cover is entirely arranged on the rubber gasket and fixed to the cylinder body by use of a bolt. As the rubber gasket is arranged between the cylinder body and the cylinder cover, the noise reduction cylinder is good in airtightness; even after working at a high temperature for a long time and being impacted by a piston, the rubber gasket does not deform and is free from air leak; meanwhile, the square groove of the cylinder cover provides a buffering region; the cylinder cover is entirely arranged on the rubber gasket, so that, when the cylinder works, a buffering acting force is generated for the piston when impacting on the cylinder cover, and therefore, noise can be reduced.

Description

A kind of noise abatement cylinder

Technical field

The present invention relates to a kind of noise abatement cylinder, belong to mechanical equipment technical field.

Background technique

Existing cylinder as shown in Figure 1, in use, owing to only having an O RunddichtringO 6 between cylinder head 2 and cylinder body 1, after hot operation and piston 3 clash into for a long time, easily make O RunddichtringO 6 damage, thereby make cylinder tightness not good, gas leakage, causes cylinder operation to occur abnormal, simultaneously, the cylinder head 2 of this structure is thicker with the thickness of piston 3 surface of contact, in the time that piston 3 and cylinder head 2 are collided, easily causes larger noise.

Summary of the invention

For the technical problem of above-mentioned existence, the object of the invention is: proposed the noise abatement cylinder that a kind of good airproof performance and noise are little.

Technical solution of the present invention is achieved in that a kind of noise abatement cylinder, comprises cylinder body, cylinder head, piston, between described cylinder body and cylinder head, is provided with rubber gasket; Described cylinder head entirety pads on rubber gasket, and is bolted on cylinder body.

Preferably, described cylinder head inside offers square groove.

Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:

A kind of noise abatement cylinder of the present invention, by between cylinder body and cylinder head, rubber gasket being set, good airproof performance, after long-time hot operation and piston slap, rubber gasket can not be out of shape, also can not leak gas, meanwhile, the square groove in cylinder head provides a buffer area, cylinder head entirety pad is on rubber gasket, when cylinder operation, piston slap has a buffer function power in cylinder head time, can noise decrease.

Brief description of the drawings

Below in conjunction with accompanying drawing, technical solution of the present invention is described further:

The structural representation that accompanying drawing 1 is existing cylinder;

Accompanying drawing 2 is the structural representation of a kind of noise abatement cylinder of the present invention;

Wherein: 1, cylinder body; 2, cylinder head; 3, piston; 4, rubber gasket; 5, square groove; 6, O RunddichtringO.

Embodiment

Below in conjunction with accompanying drawing, the present invention is described.

Be a kind of noise abatement cylinder of the present invention as shown in Figure 2, comprise cylinder body 1, cylinder head 2, piston 3, described cylinder head 2 inside offer square groove 5, in square groove 5 for piston 3 tail ends provide a buffer area in the time drawing back, in the time of piston 3 back and forth movement, the space that square groove 5 provides just in time makes piston 3 motions have a buffering, the collision that alleviates piston 3 and cylinder head 2; Between described cylinder body 1 and cylinder head 2, be provided with rubber gasket 4, and cylinder head 2 entirety pads are on rubber gasket 4, and be bolted on cylinder body 1, can make like this good seal performance between cylinder body 1 and cylinder head 2, rubber gasket 4 had both played the effect of sealing, gap between cylinder body 1 and cylinder head 2 is blocked, and the impact force producing in the time that piston 3 moves for cylinder body 1 and cylinder head 2 again provides buffering, reduces piston 3 and clashes into the noise that cylinder head is sent.

The present invention by arranging rubber gasket 4 between cylinder body 1 and cylinder head 2, good airproof performance, after long-time hot operation and piston 3 shocks, rubber gasket 4 can not be out of shape, and also can not leak gas, simultaneously, square groove 5 in cylinder head 2 provides a buffer area, and cylinder head 2 entirety pads are on rubber gasket 4, when cylinder operation, piston 3 has a buffer function power while impinging upon in cylinder head 2, can noise decrease.

Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.

Claims (2)

1. a noise abatement cylinder, comprises cylinder body, cylinder head, piston, it is characterized in that: between described cylinder body and cylinder head, be provided with rubber gasket; Described cylinder head entirety pads on rubber gasket, and is bolted on cylinder body.
2. a kind of noise abatement cylinder as claimed in claim 1, is characterized in that: described cylinder head inside offers square groove.
