Abstract
An embedded expansion self-locking seal structure comprises a carburetor and an air inlet tube. An air inlet and an air outlet are formed in a connection end surface of the carburetor, the air inlet tube which is an air inlet hose is mounted on the connection end surface in a seal mode, and the air inlet hose comprises an air inlet channel and an air outlet channel. An air inlet circular groove is formed in a ring of the outside of the air inlet, and an air outlet circular groove is formed in a ring of the outside of the air outlet. The end of the air inlet channel is embedded in the air inlet circular groove, and the end of the air outlet channel is embedded in the air outlet circular groove. The structure is good in seal property and convenient to assemble.
Description
Technical field
The utility model relates to a kind of self-locking sealing structure.
Background technique
In traditional Carburetor, not only primary venturi and pressure inlet are assembling separately, complex structure, and also suction tude and Carburetor be simple concavo-convex cooperation, has matching defect and sealing problem, between while Carburetor and cylinder, has certain vibration.
Summary of the invention
For overcome existing Carburetor gas tightness bad, assemble inconvenient deficiency, the utility model provides a kind of sealing embedded expansion self-locking sealing configuration good, easy to assembly.
The utility model solves the technological scheme that its technical problem adopts:
A kind of embedded expansion self-locking sealing configuration, comprise Carburetor and suction tude, the connecting end surface of described Carburetor has suction port and air outlet, described suction tude sealing is arranged on described connecting end surface, described suction tude is air induction hose, described air induction hose comprises gas-entered passageway and outlet passageway, the outer circle of described suction port has air inlet annular groove, outside described air outlet, a circle has out compression, described gas-entered passageway end is embedded in described air inlet annular groove, described in described outlet passageway end is embedded into, goes out in compression.
Further, described sealing configuration also comprises fixed base, on described fixed base, have mounting hole, described mounting hole is provided with shoulder towards the outside circle of described Carburetor one side, described air induction hose end is provided with back-up ring, the end of described air induction hose is through described mounting hole, and described shoulder is sleeved on described back-up ring outer ring.
Further, described air induction hose is rubber hose.
The beneficial effects of the utility model are mainly manifested in: suction tude adopts rubber hose, and has concentrated primary venturi and pressure inlet, has solved the labyrinth of the independent assembling of traditional primary venturi and pressure inlet; Between this structure air induction hose and Carburetor, adopt embeddedly, expansion self-locking sealing configuration after compressing, has solved the matching defect that simple concavo-convex cooperation exists, with the sealing problem existing; The rubber hose of itself has realized again the vibration between buffering Carburetor and cylinder; Simple in structure, easy to assembly, sealing junction reaches vacuum effectiveness, realizes the object of supercharging.

Fig. 1 is the sectional drawing of embedded expansion self-locking sealing configuration.
Fig. 2 is the enlarged view of A in Fig. 1.
Fig. 3 is the structure elucidation figure of embedded expansion self-locking sealing configuration.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1～Fig. 3, a kind of embedded expansion self-locking sealing configuration, comprise Carburetor 1 and suction tude, the connecting end surface of described Carburetor 1 has suction port and air outlet, described suction tude sealing is arranged on described connecting end surface, described suction tude is air induction hose 3, described air induction hose 3 comprises gas-entered passageway 31 and outlet passageway 32, the outer circle of described suction port has air inlet annular groove 41, outside described air outlet, a circle has out compression 42, described gas-entered passageway 31 ends are embedded in described air inlet annular groove 41, described in being embedded into, described outlet passageway 32 ends go out in compression 42.
Further, described sealing configuration also comprises fixed base 2, on described fixed base 2, have mounting hole, described mounting hole is provided with shoulder towards the outside circle of described Carburetor 1 one sides, described air induction hose 3 ends are provided with back-up ring, the end of described air induction hose 2 is through described mounting hole, and described shoulder is sleeved on described back-up ring outer ring.
Further, described air induction hose 3 is rubber hose.
In the present embodiment, described gas-entered passageway 31 is not connected with outlet passageway 32, be connected with described Carburetor 1 corresponding pipeline respectively, described air induction hose 3 is rubber hose, when its compressive deformation, described rubber hose can described air inlet annular groove 41 and described in to go out 42 li of change of compression swollen, fill up simultaneously described air inlet annular groove 41 with described in go out compression 42, now just well realized sealing effect, described gas-entered passageway 31 and described outlet passageway 32 can not leak gas mutually yet.
The utility model is mainly applied on the chain saw supporting with small utility gasoline engine.
