Abstract
The utility model discloses the seal ring of the sheathed casing of underground communication circuit, this sheathed casing 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 sheathed casing one end is set to bellmouth, the other end is formed as socket, this socket external diameter and bellmouth internal diameter suitable; Sealing circle has at least two and is tightly placed in circle body at least two adjacent troughs of bellows and an intermediate section linked together by these at least two circle bodies respectively.Its tool has the following advantages: seal ring disengaging configuration when can avoid two sheathed casing attachings, ensures assembling accuracy, improves and prepare efficiency; Intermediate section is enclosed within crest, ensures that intermediate section abuts against bellmouth inwall, ensures the radial clearance seals between two sheathed casings.
Description
Technical field
The utility model relates to a kind of seal ring of sheathed casing of underground communication circuit.
Background technique
The sheathed casing 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 sheathed casing 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 effect is poor; 2, when two sheathed casings are connected, seal ring easily overturns and departs from trough.
Model utility content
The utility model provides the seal ring of the sheathed casing of underground communication circuit, which overcomes the deficiency existing for seal ring of sheathed casing in background technique.
The technological scheme adopted that the utility model solves its technical problem is:
The seal ring of the sheathed casing of underground communication circuit, this sheathed casing 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 sheathed casing 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 at least two and is tightly placed in circle body (51) in adjacent at least two troughs (22) of bellows (20) and an intermediate section (52) linked together by these at least two circle bodies (51) respectively.
Among one embodiment: sealing circle (50) part is stretched out outside crest (21).
Among one embodiment: this circle body (51) number is two.
Among one embodiment: be convexly equipped with two lips (511) outside this circle body (51) and the disconnected cross section one-tenth Y-shaped structure of circle body (51); This intermediate section (52) is annular solid, and two peripheries of this intermediate section (52) connect a lip (511) of two circle bodies (51) respectively; And sealing circle (50) is one-body molded.
The technical program is compared with background technique, and its tool has the following advantages:
Sealing circle has at least two and is tightly placed in circle body at least two adjacent troughs of bellows and an intermediate section linked together by these at least two circle bodies respectively, then overcome the deficiency existing for background technique, and have following technique effect: a, be tightly placed at least two troughs respectively due at least two circle bodies, at least two circle bodies link together by intermediate section, seal ring disengaging configuration when therefore can avoid two sheathed casing attachings, ensure assembling accuracy, improve and prepare efficiency; B, intermediate section are enclosed within crest, ensure that intermediate section abuts against bellmouth inwall, ensure the radial clearance seals between two sheathed casings.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The schematic diagram that two sheathed casings that Fig. 1 depicts the underground communication circuit of the present embodiment are assembled together.
Embodiment
Please refer to Fig. 1, a kind of sheathed casing 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 sheathed casing one end is set to bellmouth 30, and this bellmouth 30 has ladder 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 sheathed casing to make the socket 40 of this sheathed casing.
Sealing circle 50 is one-body molded, and has two and be tightly placed in circle body 51 in two adjacent troughs 22 of bellows 20 and an intermediate section 52 linked together by these two circle bodies 51 respectively.
Be convexly equipped with two lips 511 outside this circle body 51 and the disconnected cross section one-tenth Y-shaped structure of circle body 51, sealing circle 50 part is stretched out outside crest 21.This intermediate section 52 is annular solid, and two peripheries of this intermediate section 52 connect a lip 511 of two circle bodies 51 respectively.
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.
