Abstract
The utility model discloses a kind of sealing ring of protecting pipe.This protecting pipe comprises supervisor and bellows, and this bellows-sheathed is located at outside supervisor, the trough internal diameter of this bellows and supervisor's external diameter adaptive and weld together, this protecting pipe one end is set to bellmouth, and the other end is formed as socket.Sealing circle has shim portions and coupling part main part and shim portions linked together that a main part, be tightly placed in the trough of bellows abuts against socket axis end face.Its tool has the following advantages: a, abut against socket axis end face due to shim portions, and when therefore can avoid two protecting pipe attachings, sealing ring disengaging configuration, ensures assembling accuracy, improve and prepare efficiency; B, owing to there is shim portions, therefore can increase between two protecting pipes end play sealing, good seal performance; C, coupling part are enclosed within crest, ensure that coupling part abuts against bellmouth inwall, ensure the radial clearance seals between two protecting pipes.
Description
Technical field
The utility model relates to a kind of sealing ring of protecting pipe of underground communication circuit.
Background technology
The protecting pipe of traditional underground communication circuit comprises the bellows that a supervisor and has crest and trough, this bellows-sheathed is located at outside supervisor, the trough internal diameter of this bellows and supervisor's external diameter adaptive and weld together, this protecting pipe one end is set to bellmouth, the other end is formed as socket, this socket external diameter and bellmouth internal diameter suitable.Sealing circle is tightly placed in the trough of bellows.Sealing circle section is O shape structure, and it has following deficiency: 1, sealing effectiveness is poor; 2, when two protecting pipes are connected, sealing ring easily overturns and departs from trough.
Utility model content
The utility model provides a kind of sealing ring of protecting pipe, which overcomes the deficiency existing for sealing ring of protecting pipe in background technology.
The technical scheme adopted that the utility model solves its technical problem is:
A kind of sealing ring of protecting pipe, this protecting pipe comprises the bellows (20) that a supervisor (10) and has crest (21) and trough (22), this bellows (20) is set in supervisor (10) outward, trough (22) internal diameter of this bellows (20) and supervisor (10) external diameter are adaptive and weld together, this protecting pipe one end is set to bellmouth (30), the other end is formed as socket (40), this socket (40) external diameter and bellmouth (30) internal diameter suitable; Sealing circle (50) has shim portions (52) and the coupling part (53) main part (51) and shim portions (52) linked together that a main part (51), be tightly placed in the trough (22) of bellows (20) abuts against socket (40) axial end.
Among one embodiment: sealing circle (50) part is stretched out outside crest (21).
Among one embodiment: sealing circle (50) number is one.
Among one embodiment: the main part (51) of sealing circle (50) is connected to the trough (22) formed between two crests (21) near socket (40) axial end.
Among one embodiment: this coupling part (53) are for turning round shell-like and being enclosed within outside protecting pipe.
Among one embodiment: be convexly equipped with two lips (511) outside this main part (51) and the disconnected cross section of main part (51) becomes Y-shaped structure, this lip near shim portions (52) (511) extends to shim portions (52) direction and attachment spacers part (52) be formed as above-mentioned coupling part (53).
The technical program is compared with background technology, and its tool has the following advantages:
1, the sealing ring main part, had in a trough be tightly placed in abuts against shim portions and coupling part main part and shim portions linked together of socket axis end face, therefore the deficiency existing for background technology is overcome, and have following technique effect: a, abut against socket axis end face due to shim portions, sealing ring disengaging configuration when therefore can avoid two protecting pipe attachings, ensure assembling accuracy, improve and prepare efficiency; B, owing to there is shim portions, therefore can increase between two protecting pipes end play sealing, good seal performance; C, coupling part are enclosed within crest, ensure that coupling part abuts against bellmouth inwall, ensure the radial clearance seals between two protecting pipes.
2, single sealing ring can realize sealing between adjacent two protecting pipes be connected and interference fit.
3, outer projection two lip of main part and main part is divided into Y-shaped structure, this lip near shim portions extends and attachment spacers part be formed as above-mentioned coupling part, good seal performance to shim portions.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The schematic diagram that two protecting pipes that Fig. 1 depicts the underground communication circuit of the present embodiment are assembled together.
Fig. 2 depicts the schematic diagram in the disconnected cross section of the sealing ring of the present embodiment.
Embodiment
Please refer to Fig. 1 and Fig. 2, a kind of protecting pipe of underground communication circuit, comprise the bellows 20 that a supervisor 10 and has crest 21 and trough 22, this bellows 20 is set in outside supervisor 10, trough 22 internal diameter of this bellows 20 and supervisor 10 external diameters adaptive and weld together; This protecting pipe one end is set to bellmouth 30, and this bellmouth 30 has cascaded surface 31, and the other end is formed as socket 40, and this socket 40 external diameter is slightly less than in bellmouth 30, can insert in the bellmouth 30 of another protecting pipe to make the socket 40 of this protecting pipe.
Sealing circle 50 has shim portions 52 and the coupling part 53 main part 51 and shim portions 52 linked together that a main part 51, be tightly placed in the trough 22 of bellows 20 abuts against socket 40 axial end.The main part 51 of sealing circle 50 is connected to the trough 22 formed between two crests 21 near socket 40 axial end.Best, cross section becomes Y-shaped structure and main part 51 is broken to be convexly equipped with two lips 511 outside this main part 51, this lip 511 near shim portions 52 extends and attachment spacers part 52 be formed as above-mentioned coupling part 53, to make to shim portions 52 direction: this coupling part 53 is for revolution shell-like and be enclosed within outside protecting pipe; This lip 511 stretches out outside crest 21.
Among the present embodiment: sealing circle 50 number is one.
Among the present embodiment, when two protecting pipes are connected, first sealing ring is connected to outside the socket of a protecting pipe, then this socket is injected in the bellmouth of another protecting pipe, then: this lip 511, coupling part abut against bellmouth inwall, realize radial clearance seals, this shim portions abuts against between socket end face and cascaded surface and realizes end play sealing, and, because sealing ring abuts against bellmouth inwall, the bellmouth of two protecting pipes and socket is also made to realize interference fit by sealing ring, to locate interlocking.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
