Defensively anti-strain method and apparatus

Abstract

The invention discloses a defensively anti-strain method and apparatus, and the apparatus comprises an annular body that has multiple bearing segments, inclining segments and groove segments, wherein, the inclining segments are arranged by intervals in order; the apparatus also comprises a buried rubber shock connector or a rubber soft shock absorber, and a water sealer like a waterproof washer or an O-shaped ring. According to the defensively anti-strain method and apparatus, water preventing and waterproof functions are realized; the rubber is prevented from aging or from breaking under outside pressure effectively; a steel rope is replaced and bad influence like the steel rope breaking into steel wire to cut the rubber because of being squeezed; water preventing and waterproof functions are enhanced; and the rubber shock connector or the rubber soft shock absorber, and the water sealer like the waterproof washer or the O-shaped ring are prevented from distortion or breaking because of strain generated by locking at the joint of two surfaces.

Description

technical field [0001] The invention belongs to the technical field of rubber joints, and in particular relates to a strain-resisting method and a device thereof. Background technique [0002] When a material cannot be displaced under the action of an external force, its geometry and size will change. This deformation is called strain. When the material is deformed, a reaction force of equal size but opposite direction is generated inside to resist the external force, and this reaction force per unit area is defined as stress. Or when an object is deformed due to external factors (force, humidity change, etc.), the internal force of interaction is generated between the various parts of the object to resist the effect of this external factor, and try to make the object return from the deformed position to the pre-deformed position s position. The internal force per unit area at a point on the section under consideration is called stress. According to the directional relati...

Problems solved by technology

At present, conventional rubber anti-vibration joints or soft joint shock absorbers or O-rings and waterproof gaskets in the general prior art, especially rubber anti-vibration joints or rubber soft joint shock absorbers, in order to strengthen the fixing force and water-stop effect, usually Buried a ring-shaped steel cable at the edge of the opening, restrained by the steel cable, it has been done for many years to strengthen the airtightness and fixation of the pipeline shock absorber, and to achieve the effect of decompression. However, the prior art has always been Traditional rubber anti-vibration joints or soft joint shock absorbers or O-rings, waterproof gaskets, especially rubber anti-vibration joints or rubber soft joint shock absorbers, because the steel cables are braided by multiple steel wires, when rubber anti-vibration joints are installed Extruded by the flange, the opening of the rubber anti-vibration joint will expand outwards and become thinner and flattened. After a period of use, it will not only cause the bolts and nuts locking the flange to loosen, but the locking and water leakage must be checked frequently conditions, and may cause stress at the joints of the two sides, resulting in distortion, cracking, deformation of the rubber and steel cables (the circle is extruded into an ellipse) and affects the water-stop effect. Moreover, there are always some The steel wire will protrude and pierce the periphery of the rubber anti-vibration joint, making the rubber anti-vibration joint leaking.
