Description

Novel rubber and plastic composite waterproof bolt

Technical Field

The utility model relates to the technical field of waterproof plugs, in particular to a novel rubber-plastic composite waterproof plug.

Background

The waterproof plug is also called as a waterproof plug or a waterproof ring, a waterproof plug and a waterproof pad, and is generally divided into a solid part and a hollow part according to the structure, the main function is to seal the pipeline in the aspect of water leakage of the pipeline, the definition of sealing refers to tight sealing, the sealing is a part or measure for preventing fluid or solid particles from leaking from adjacent joint surfaces and preventing external impurities such as dust, moisture and the like from invading into the interior of machine equipment, and the sealing can be divided into static sealing and dynamic sealing. The static seal mainly comprises pad seal, sealant seal and direct contact seal. The static seal can be divided into medium-low pressure static seal and high pressure static seal according to the working pressure. The medium and low pressure static seal is usually sealed by a cushion made of a softer material and wider in width, and the high pressure static seal is sealed by a metal gasket made of a harder material and narrower in contact width. Dynamic seals can be divided into two basic types, rotary seals and reciprocating seals. Whether other parts which move relatively to the sealing element are contacted or not can be divided into contact type sealing and non-contact type sealing; depending on the sealing element and the contact position, these can be further divided into circumferential sealing and end face sealing, which are also referred to as mechanical seals. Centrifugal sealing and spiral sealing in dynamic sealing are sealed by means of dynamic force applied to media when a machine operates, so that the dynamic sealing is sometimes called as dynamic sealing, and a waterproof plug is widest in application range in the field of automobile sealing at present.

The use of current waterproof plug is only simple utilizes external force to its extrusion, makes it laminate mutually with the pipeline inner wall to reach the effect that prevents the water stain and spill over, but the leakproofness of the waterproof plug that this kind of mode made is relatively poor, and sealed effect is not good, therefore prior art exists not enoughly, needs improve this.
