Description
Technical field
The utility model is specifically related to a kind of end part of composite insulator sealing structure, belongs to composite insulator technical field.
Background technology
In the running of composite insulator, the sealing problem of composite insulator hardware end, plug is directly affected
Safety, if its sealing structure is destroyed, outside moisture can invade plug, so as to cause the corrosion brittle failure of plug.Prior art
Middle most of composite insulator is sealed using sheath with gold utensil end face using the bonding form of room temperature vulcanized silicone rubber circle.This
The difference of seal interface material mechanical performance, seal operation technogenic influence and fragile sealing surface be present in kind sealing means,
It is difficult to ensure that product longtime running seals stability.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of good sealing effect, sealant service life length answer
Close insulator end sealing structure.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of end part of composite insulator sealing structure, including plug, the sheath for being coated on the plug outer wall, the sheath
End sleeve be provided with gold utensil and fixing ring described in gold utensil offer cavity structure close to the side of the sheath outer wall, it is described
Fluid sealant is filled with cavity structure, the lower surface of the fixing ring is in close contact with the fluid sealant upper surface, described
Profile seal ring outer wall is arranged with retainer ring.
The thickness of the fixing ring lower surface is equal to the thickness of the fluid sealant upper surface.
The material of the retainer ring includes stainless steel.
The material of the fluid sealant includes sulphurated siliastic.
The contact surface of the fixing ring and the retainer ring include successively integrally formed inclined-plane (, horizontal plane and perpendicular
Face directly.
The outer end of the retainer ring is downwardly projecting an extension, and the outer wall of the inwall of the extension and the gold utensil is close
Contact.
The outer surface of the gold utensil is provided with cylindricality nose, is offered on the inside of the extension and the cylindricality nose
The shrinkage pool matched somebody with somebody.
The beneficial effects of the utility model：A kind of end part of composite insulator sealing structure provided by the utility model, existing
Increase fixing ring on the basis of some sealant sealings, profile seal ring outer wall is arranged with retainer ring and maintains its machinery strong
Degree, can avoid fluid sealant directly and air contact, from sun light action and external force clashing and breaking, it is maintained higher sealing
Performance and used life.
Brief description of the drawings
Fig. 1 is a kind of structural representation of end part of composite insulator sealing structure of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, following examples are only used for clearly illustrating this
The technical scheme of utility model, and the scope of protection of the utility model can not be limited with this.
As shown in figure 1, a kind of end part of composite insulator sealing structure, including plug 1, the sheath for being coated on the outer wall of plug 1
2, the end sleeve of sheath 2 is provided with gold utensil 5 and fixing ring 3, and gold utensil 5 offers cavity structure close to the side of the outer wall of sheath 2,
Fluid sealant 6 is filled with cavity structure, lower surface and the upper surface of fluid sealant 6 of fixing ring 3 are in close contact, fixing ring
3 outer walls are arranged with retainer ring 4, and fixing ring 3 is flexible, can be compressed at its contact surface with retainer ring 4.
The thickness of the lower surface of fixing ring 3 is equal to the thickness of the upper surface of fluid sealant 6.
The material of retainer ring 4 is preferably stainless steel.
The material of fluid sealant 6 is preferably sulphurated siliastic.
Fixing ring 3 and the contact surface of retainer ring 4 include integrally formed inclined-plane 31 successively, horizontal plane 32 and vertical plane
33, by increasing capacitance it is possible to increase fixation of the retainer ring 4 to fixing ring 3.
The outer end of retainer ring 4 is downwardly projecting extension 41, and the inwall of the extension 41 closely connects with the outer wall of gold utensil 5
Touch, fixation can be played to gold utensil 5.
The outer surface of gold utensil 5 is provided with cylindricality nose, the inner side of extension 4 offer matched with the cylindricality nose it is recessed
Hole, further increase the stability between retainer ring 4 and gold utensil 5.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
