Abstract

The utility model relates to the technical field of rubber sealing elements, and discloses a rubber sealing element with a buffer structure. This rubber seal spare with buffer structure, through buffer structure's setting, when the device is about to use, at first install the connecting pipe on outside pipeline, later install poling and it together through connecting bolt, at poling externally mounted shrink sealing washer, shrink sealing washer's outside has set up the buffer spring, shrink sealing washer takes the buffer spring to slide and inlays in the inside annular groove of connecting pipe, the effect of alleviating pipeline inside pressure when sealed has been played, avoid lacking buffer and absorbed and dispersed impact force, make the sealing member very fragile, be difficult to maintain good sealing state, ageing easily appears, hardening, phenomenon such as fracture, lead to the premature failure of sealing member.

Description

Rubber sealing piece with buffer structure Technical Field The utility model relates to the technical field of rubber sealing elements, in particular to a rubber sealing element with a buffer structure. Background Under many practical conditions, the rubber sealing member is subjected to various impact forces, vibration and impact are generated due to road jolts, acceleration and deceleration, and the like, the vibration and the impact are transmitted to the rubber sealing member, the impact forces are generated due to instant collision and friction between parts, and the impact forces act on the sealing member, so that the rubber sealing member can displace and deform to damage the sealing performance, and therefore, the rubber sealing member with the buffer structure is required to be designed. The traditional rubber sealing element is mainly used for basic sealing function, lacks effective buffer measures for shock impact possibly suffered by a pipeline, lacks a special buffer device for absorbing and dispersing impact force, is quite fragile when facing the shock impact, is difficult to maintain a good sealing state, is easy to cause aging, hardening, cracking and the like, is easy to cause premature failure, is internally provided with a retractable sealing buffer structure with an external spring, can effectively buffer the influence of the shock impact on the rubber sealing element, can absorb and disperse the impact force, enables the sealing element to still maintain a stable position and shape in a shock environment, is tightly attached to the inner wall of the connecting tube, improves the sealing stability and reliability, reduces leakage risk, and is quite fragile when facing complex working conditions due to the fact that the traditional rubber sealing element is neglected to protect the connecting tube and the sealing element and lacks an extra protecting device for resisting external collision, friction and environmental factors. The sealing piece with the buffer structure comprises a mounting column, a first buffer module and a second buffer module, wherein the first buffer module and the second buffer module are mounted on the mounting column, the first buffer module comprises a first mounting ring, a threaded ring, a first spring and a first gasket, the first mounting ring comprises a threaded ring mounting round surface, a first fixing baffle, a first outer ring, a large inclined surface, an inner ring, a small inclined surface and a second outer ring, the first gasket is arranged on the left side of the first mounting ring, and the two parts connected with the sealing piece can move within a certain range without loosening by arranging the two buffer modules, so that the elasticity and the stability of a connecting part are provided. The structure such as the threaded ring, the fixed baffle, the threaded groove and the threaded teeth are arranged, so that the connection is more diversified, and the connection mode is simpler. The above patent, although making a shock absorbing means for buffering the external impact force and increasing the diversity in installation, lacks a protection means for the structure itself, and may not be able to avoid damage when the shock absorbing means itself is impacted or vibrated, affecting the sealing effect and efficiency in the later stage.
