Description
Technical Field
The utility model relates to a butt-joint structure of exhaust pipe.
Background
Current collection smoke cabinet is including collection fume sucking device and fume extractor, inhales the collection smoke cabinet through collection fume sucking device to the oil smoke, outwards discharges the oil smoke from fume extractor again, and fume extractor is an wind channel that is formed by many pipe docks, can be detained a large amount of tobacco tar when the butt joint between pipeline and pipeline is not good, also can make the oil smoke in the wind channel simultaneously and leak.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a butt joint structure of exhaust pipe who easy to assemble more and have good leakproofness.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a butt joint structure of exhaust pipe, includes communicating pipe and play tuber pipe, the first end outer wall of communicating pipe is provided with the outer tube that encircles the setting of communicating pipe outer enclosure wall, the outer tube with form the U-shaped groove between communicating pipe, the one end that goes out the tuber pipe inserts in this U-shaped groove and through adhesive and communicating pipe fixed seal connection.
The utility model has the advantages of the butt joint structure between the pipeline is simple, and simple to operate and leakproofness are good.

Detailed Description
As shown in the attached drawings 1-4, a butt-joint structure of exhaust pipe, including communicating pipe 1 and play tuber pipe 2, the first end outer wall of communicating pipe 1 is provided with the outer tube 11 that encircles the setting of communicating pipe outer surrounding wall, outer tube 11 with form the U-shaped groove between communicating pipe 1, the one end of play tuber pipe 2 inserts in this U-shaped groove and through adhesive and 1 fixed sealing connection communicating pipe, foretell adhesive can be glass glues, and its beneficial effect is that the installation goes out tuber pipe 2 convenience, goes out tuber pipe 2 and is connected firmly and sealed with communicating pipe 1.
In the axial of the first end of communicating pipe 1, the first end terminal surface of communicating pipe 1 surpasss the terminal surface of outer tube 11, its beneficial effect is that the outer wall area of contact who goes out tuber pipe 2 inner wall and communicating pipe 1 increases and makes the tuber pipe 2 and be connected between 1 communicating pipe have good leakproofness, does not increase the length of outer tube 11 simultaneously, can save material and make things convenient for out tuber pipe 2 to insert in the above-mentioned U-shaped groove when having good leakproofness.
Still include collection cigarette cabinet 3 in this embodiment, collection cigarette cabinet 3 has air outlet 31, and the second pot head of communicating pipe 1 is established on air outlet 31, air outlet 31's periphery wall is provided with annular fixed slot 311, communicating pipe 1 corresponds threaded hole 12 is seted up to fixed slot 311 position, and threaded hole 12 sets the fastener and passes threaded hole 12 and block and fall in fixed slot 311 for communicating pipe 1 can not reciprocate on air outlet 31's central axis, but can rotate around its central axis, in order to supply the best air-out position of user's rotatory adjustment.
An annular sealing groove 312 is further disposed below the fixing groove 311, and a sealing rubber ring may be installed in the sealing groove 312 to prevent oil smoke from leaking.
The smoke collection cabinet 3 comprises an upper cover plate 32, a cover body 33, a lower cover plate 34 and a fan 35, wherein the upper cover plate 32 and the lower cover plate 34 are respectively packaged at the upper end and the lower end of the cover body 33, an air inlet 321 is formed in the upper cover plate 32, the fan 35 comprises an air outlet 351, an outlet 341 is formed in the lower cover plate 34, one end of the air outlet 31 is in butt joint with the air outlet 321 and is sleeved in the outlet 341, oil smoke is sucked from the air inlet 321 when the fan 35 operates, and the oil smoke is discharged from the air outlet pipe 2 through the air outlet 321 via the air outlet 31 and the communicating pipe 1.
The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto, and any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are equivalent replacement modes, and are all included in the scope of the present invention.
