Anti-collision and shock-absorbing O-shaped sealing ring

Technical Field

The utility model relates to a O type technical field specifically is a crashproof absorbing O type sealing washer.

Background

The O-shaped rubber sealing ring is formed by combining a low-friction filled Polytetrafluoroethylene (PTFE) ring and an O-shaped rubber sealing ring, and the O-shaped ring provides enough sealing pretightening force and has a compensation effect on the abrasion of the PTFE ring. The friction coefficient of PTFE is small, and the dynamic and static friction coefficients are similar. The sealing device is suitable for sealing the piston rod of the oil cylinder in high-speed and low-speed reciprocating motion and high-pressure systems. And the two stepped rings are adopted for sealing, so that zero leakage can be achieved. The O-shaped sealing ring is widely used for sealing internal combustion locomotives, automobiles, tractors, engineering machinery, machine tools, various hydraulic and pneumatic elements and the like, can bear the sealing of fixed, reciprocating and rotating motion, and accounts for more than 50 percent of the O-shaped rubber sealing ring in the sealing of mechanical products. According to the requirements, it can be used for producing various special-purpose sealing rings and special-shaped rubber sealing products for resisting high temperature, low temperature vacuum, high pressure and different media.

Through mass search, the typical shock absorption sealing ring disclosed as CN211145354U in the prior art of the anti-collision shock absorption O-shaped sealing ring is found, the problem that the existing shock absorption sealing ring is damaged when large torsion occurs is solved, and the shock absorption sealing ring is good in practicability, easy to popularize and apply and high in value.

Equipment can produce certain vibrations at the in-process of operation to can cause the local atress of O type sealing washer too big production compression, and another part atress is less then can break away from with equipment, makes O type sealing washer then lose sealed effect, for this reason, we provide a crashproof absorbing O type sealing washer.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a shock-absorbing O type sealing washer of anticollision possesses the advantage that improves the shock attenuation effect of O type sealing washer when can improve the sealed effect of O type sealing washer, has solved equipment and can produce certain vibrations at the in-process of operation to can cause the too big production compression of O type sealing washer local atress, and another part atress is less then can break away from with equipment, then makes O type sealing washer lose the problem of sealed effect.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a crashproof absorbing O type sealing washer, includes rubber ring, sealing washer main part and damping oil, sealing washer main part internally mounted has the block rubber, the inside intercommunicating pore that is equipped with of block rubber, sealing washer main part surface is equipped with annular dovetail, annular dovetail internally mounted has the dovetail, dovetail surface mounting has the rubber ring, surface mounting has the wearing layer under the sealing washer main part.

Preferably, the rubber blocks are six in number, and the six rubber blocks are arranged in the sealing ring main body in an annular array at equal intervals. Six rubber blocks make the inside of the sealing ring main body divide the cavity.

Preferably, the number of the communication holes is six, and the six communication holes are respectively arranged in the six rubber blocks. The six communication holes are convenient for damping oil to flow in the sealing ring main body.

Preferably, the annular dovetail grooves are provided with two annular dovetail grooves which are respectively arranged on the outer surface and the inner wall of the sealing ring main body, the two annular dovetail grooves are internally provided with dovetail rings, and the outer surfaces of the dovetail rings are provided with rubber rings. When the installation position of the sealing ring of the device is too large or too small, the dovetail ring and the rubber ring can be additionally installed or not installed, so that the universality of the main body of the sealing ring is improved.

Preferably, the wear-resisting layers are two in number and are symmetrically arranged on the upper surface and the lower surface of the sealing ring main body. The arrangement of the two wear-resistant layers can prevent the sealing ring main body from being greatly abraded to form a sealing gap, so that the sealing effect of the sealing ring main body is ensured.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses a set up block rubber and damping oil, improved O type sealing washer's shock attenuation effect when having reached and improving the sealed effect of O type sealing washer, six block rubbers make six inside cavities of cutting apart of sealing washer main part, and six intercommunicating pores make six cavity intercommunications, when the sealing washer main part receives the vibrations extrusion of equipment, the inside damping oil of six cavities flows, receive the flow potential energy that vibrations extrusion becomes damping oil with the sealing washer main part, improve the shock-absorbing capacity of sealing washer main part, when the sealing washer main part receives local extrusion pressure degree too big and compress simultaneously, the inside damping oil of sealing washer main part flows into the inside this partial inflation and the equipment contact of making of the less cavity of another part atress, guarantee the sealed effect of sealing washer main part.

2. The utility model discloses a set up dovetail and rubber ring, reached and to have improved the effect of O type sealing washer commonality, too big or when the sealing washer mounted position of equipment is too little, can add the installation or do not install dovetail ring and rubber ring.
