It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.
Referring to figs. 1 to Fig. 3, a kind of self-locking plug for seal device, including support base 20 and gland 10 positioned opposite,
It is both in round pie, the diameter of gland 10 is greater than the diameter of support base 20, and support base 20, which is disposed with, drives its own court
The mobile adjusting component of gland 10, adjusting component, which specifically includes, to be vertically fixed in the adjusting screw rod 51 of support base 20 and is screwed in
Adjusting nut 52 on 51 external screw thread of adjusting screw rod, the adjusting nut 52 are pressed on 10 end face outside of gland, and gland 10 is arranged
There is the first through hole passed through for adjusting screw rod 51.It is disposed with seal assembly between support base 20 and gland 10, the seal assembly
Including being pressed on the elastic sealing element 30 of 20 end face of support base and being pressed on the elasticity of 30 other end of elastic sealing element
Retaining ring 40, the inner side end of gland 10 are disposed with the rotary table 11 towards circlip 40,40 internal perisporium of circlip be disposed with
The conical surface 41 that 11 side of rotary table matches.Specifically, adjusting screw rod 51 is welded in support base 20.
When the utility model is used, 10 end face edge of gland is resisted against pipe end, screws adjusting nut 52, drives and adjusts
It saves screw rod 51 to move axially, and then keeps support base 20 mobile towards 10 direction of gland.11 side of rotary table compresses circlip at this time
On 40 conical surface 41,11 side of rotary table has the radial force for being applied to circlip 40, therefore circlip 40 can deform,
40 portions of lateral side of circlip is pressed on steel pipe inner wall, i.e. circlip 40 and steel pipe is interference fit, to reach self-locking
Tight function.Circlip 40 has an opening 42, it is possible to provide the space that circlip 40 deforms, be open 42 shapes such as Fig. 3 institute
Show, is to anxious.In addition, support base 20 compresses the one of elastic sealing element 30 when support base 20 is mobile towards 10 direction of gland
End, and elastic sealing element 30 shifts circlip 40 onto and is applied to elastic gear toward when the movement of 10 direction of gland, 11 side of rotary table has
The axial force of circle 40, circlip 40 compress the other end of elastic sealing element 30, and support base 20 and circlip 40 are pressed respectively
The both ends of tight elastic sealing element 30, elastic sealing element 30 deform, and periphery wall is pressed on steel pipe inner wall, to reach sealing
