Abstract
The utility model discloses a kind of protecting pipe hermetically-sealed construction of underground communication circuit.This protecting pipe comprises supervisor and bellows, and bellows-sheathed is located at outside supervisor, the trough internal diameter of bellows and supervisor's external diameter adaptive and weld together.This protecting pipe one end is set to bellmouth, and bellmouth has cascaded surface, and the other end is formed as socket, and the socket adaptation of this protecting pipe is inserted in the bellmouth of another protecting pipe.The gasket seal of another arranging sealing ring and annular; Sealing circle is tightly placed in the trough of the jack part of the bellows of protecting pipe, and sealing ring part to be stretched out outside crest and is tight against the bellmouth part of the supervisor at another protecting pipe; Gasket seal is sealingly connected between the cascaded surface of the socket end face of this protecting pipe and the bellmouth of this another protecting pipe.Its tool has the following advantages: the gap being sealed bellmouth and socket by sealing ring, the radial clearance of sealing sheath pipe, and sealed the end play of bellmouth and socket by gasket seal, good seal performance, can effectively avoid moisture to enter in protecting pipe.
Description
Technical field
The utility model relates to a kind of protecting pipe hermetically-sealed construction of underground communication circuit.
Background technology
The syndeton of the protecting pipe of existing underground communication circuit, adjacent two protecting pipes connect, this protecting pipe comprises the bellows that a supervisor and has crest and trough, 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 this bellmouth has cascaded surface, and the other end is formed as socket, and the socket adaptation of this protecting pipe is inserted in the bellmouth of another protecting pipe.Because this protecting pipe is embedded in underground, underground water branch is infiltrated in protecting pipe by the gap of bellmouth and socket, and defective communication circuit, as cable or electric wire etc., therefore has necessity of improvement.
Utility model content
The utility model provides a kind of protecting pipe hermetically-sealed construction of underground communication circuit, which overcomes the deficiency existing for protecting pipe syndeton of underground communication circuit in background technology.
The technical scheme adopted that the utility model solves its technical problem is:
A kind of protecting pipe hermetically-sealed construction of underground communication circuit, connect adjacent two protecting pipes, 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, and 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), this bellmouth (30) has cascaded surface (31), the other end is formed as socket (40), and socket (40) adaptation of this protecting pipe is inserted in the bellmouth (30) of another protecting pipe;
The gasket seal (60) of another arranging sealing ring (50) and annular; Sealing circle (50) is tightly placed in the trough (22) of socket (40) part of the bellows (20) of a protecting pipe, and sealing circle (50) part to be stretched out outside crest (21) and is tight against bellmouth (30) part of the supervisor (10) at another protecting pipe; Sealing pad (60) is sealingly connected between the cascaded surface (31) of socket (40) end face of this protecting pipe and the bellmouth (30) of another this protecting pipe.
Among one embodiment: the external diameter of the crest (21) of socket (40) part of this bellows (20) is less than the internal diameter of bellmouth (30) part of supervisor (10); Sealing circle (50) maximum outside diameter is greater than crest (21) external diameter of socket (40) part of bellows (20), and sealing circle (50) maximum outside diameter is greater than the internal diameter of bellmouth (30) part of supervisor (10).
Among one embodiment: sealing pad (60) thickness is greater than the spacing of socket (40) end face of this protecting pipe and the cascaded surface (31) of another this protecting pipe.
The technical program is compared with background technology, and its tool has the following advantages:
Sealed the gap of bellmouth and socket by sealing ring, the radial clearance of sealing sheath pipe, sealed the end play of bellmouth and socket by gasket seal, good seal performance, can effectively avoid moisture to enter in protecting pipe.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 depicts the schematic diagram of the protecting pipe hermetically-sealed construction of the underground communication circuit of the present embodiment.
Embodiment
Please refer to Fig. 1, a kind of protecting pipe hermetically-sealed construction of underground communication circuit, connect adjacent two protecting pipes, this protecting pipe comprises 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 the socket 40 of this protecting pipe can adaptation insert in the bellmouth 30 of another protecting pipe.
The gasket seal 60 of another arranging sealing ring 50 and annular.Sealing circle 50 is tightly placed in the trough 22 of socket 40 part of the bellows 20 of a protecting pipe, and sealing circle 50 part to be stretched out outside crest 21 and is tight against bellmouth 30 part of the supervisor 10 at another protecting pipe, realizes radial seal with this.Sealing pad 60 is sealingly connected between the cascaded surface 31 of socket 40 end face of this protecting pipe and the bellmouth 30 of another this protecting pipe, realizes axial seal with this.
In one preferred version, the external diameter of the crest 21 of socket 40 part of this bellows 20 is less than the internal diameter of bellmouth 30 part of supervisor 10; Sealing circle 50 maximum outside diameter is greater than crest 21 external diameter of socket 40 part of bellows 20, and sealing circle 50 maximum outside diameter is greater than the internal diameter of bellmouth 30 part of supervisor 10, to be tightly connected socket and bellmouth to make sealing ring.Sealing pad 60 thickness is greater than the spacing of socket 40 end face of this protecting pipe and the cascaded surface 31 of another this protecting pipe.
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.
