Description

Technical Field

[0001] The utility model relates to a metal - clad seal, belonging to the technical field of metal seals. Background Technique

[0002] The metal - clad seal is mainly used for sealing the leaky openings of metal parts by means of socketing, etc. The seal material includes metal materials, non - metal materials and composite materials, but the most used is rubber - like elastomer materials;

[0003] For example, an insertion - type metal seal with the patent publication number of CN202220364369.0, which relates to the technical field of mechanical seals, includes: a metal sealing ring and a wedge - shaped push ring. The wedge - shaped push ring includes: an extrusion head. The metal sealing ring includes: an inner sealing wall, an outer sealing wall and an elastic part. A first annular groove is arranged between the inner sealing wall and the outer sealing wall. A metal sealing ring is arranged on the inner sealing wall. An elastic part is arranged on the outer sealing wall. The elastic part is arranged at the notch position of the first annular groove on the outer sealing wall. A second annular groove is arranged between the elastic part and the outer sealing wall. The notch orientation of the second annular groove is opposite to that of the first groove. The extrusion head is nested in the first annular groove. The extrusion head makes the notch of the first annular groove open. The elastic part fits on the inner wall of the sleeve. The metal sealing ring fits on the mandrel;

[0004] Since the above - mentioned metal seal performs sealing treatment at the metal part through the insertion effect, but the overall external anti - collision protection effect is limited, and the metal seal after socketing is positioned and sealed by extrusion, which is prone to loosening, slipping and deformation during long - term use, bringing certain adverse effects to the actual use. Therefore, improvement is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a metal - clad seal. The metal - clad seal of the utility model can seal the metal part through a ring - wrapped seal sleeve composed of different materials, and an extended protection plate is added for positioning and protective sealing. A collision - proof outer sleeve and an outer seal are provided to protect the metal part at the sealing position and the outside of the metal seal, so as to solve the problems raised in the above - mentioned background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A metal-wrapped seal includes a ring-wrapped seal sleeve. A seal cover ring is fixedly connected to the inner wall of the ring-wrapped seal sleeve. Anti-contact soft pads are fixedly connected to both the top and bottom of the seal cover ring. Plug-in slots are provided near the top and bottom of the side of the ring-wrapped seal sleeve.

A spring telescopic rod is fixedly installed on the inner wall of the groove. An anti-contact locking plate is fixedly connected to the side of the spring telescopic rod.

[0008] Furthermore, the main body of the ring-wrapped seal sleeve is an elastic seal ring. A metal outer protection plate is fixedly connected to the outside of the elastic seal ring. An anti-corrosion coating is filled on the outer surface of the metal outer protection plate.

[0009] Furthermore, an anti-collision outer sleeve is fixedly connected to the outside of the ring-wrapped seal sleeve. The material of the anti-collision outer sleeve is cis-butadiene rubber.

[0010] Furthermore, anti-slip restraint grooves are provided at both the top and bottom of the anti-collision outer sleeve. An anti-slip restraint rod is clamped to the inner wall of the anti-slip restraint groove. One end of the anti-slip restraint rod is fixedly connected to an outer seal sleeve. The inner wall of the outer seal sleeve abuts against the surface of the extended protection plate.

[0011] Furthermore, the overall shape of the anti-contact locking plate is a U-shaped plate. A magnetic adsorption fixing plate is fixedly connected to the side of the anti-contact locking plate. The surface of the anti-contact locking plate is slidably connected to the inner wall of the groove.

[0012] Furthermore, a guiding plate is fixedly connected to the surface of the anti-contact locking plate. A guiding groove is provided on the surface of the inner wall of the groove. The inner wall of the guiding groove is slidably connected to the surface of the guiding plate.

[0013] The beneficial effects of the present utility model are:
