Currently, most automobile air-conditioning throttle sealing still pastes sponge on Plastic Air Door and comes seal casinghousing and wind
Door, but this sealing structure effect is not ideal enough, and in technique after the completion of air door and sponge produce, it is also necessary to worker is manual
Sponge is pasted on air door, process flow is relatively complicated, and air door sealing effect is not good enough.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of automobile air-conditioning throttle
Sealing structure and its installation method,
In order to solve the above technical problems, the technical scheme is that a kind of sealing structure of automobile air-conditioning throttle, including
Air door ontology, air door sealing edge, the air door sealing edge are connect with air door ontology, and the air door ontology is equipped with cantilever arm,
The air door sealing edge is equipped with the annular wall being socketed on the cantilever arm, and the sealing structure further includes shell, described
Annular wall and cantilever arm between be equipped with gap and form annular seal groove, the shell connect with the air door sealing edge,
The shell is equipped with the annular lug protruded into the annular seal groove.
The air door sealing edge is equipped with sealing bar, the sealing bar be arranged in the air door sealing edge with it is described
Shell between gap in.
The annular lug shape and ring packing groove shape is adapted.
The section of the annular lug is trapezium structure.
The shell is equipped with clamping wall.
The air door ontology is rubber air door, and the shell is plastic casing, the air door ontology and shell it
Between contact surface on be coated with lubricant grease.
The air door sealing edge is rubber seal side, and the sealing bar is rubber seal muscle.
A kind of installation method of the sealing structure of automobile air-conditioning throttle, the method the following steps are included:
A) air door sealing edge becomes an entirety by processing technology and air door the ontology production of secondary injection molding；
B) lubricant grease is coated on the contact surface between air door ontology and shell；
C) the air door ontology for being coated with lubricant grease is assembled together with shell, it is ensured that the annular lug on shell is assemblied in
In annular seal groove；
D) sealing bar on air door sealing edge is fitted closely with shell.
The present invention using the above structure and method, has the advantage that 1, this air door structure using secondary injection molding
Processing technology enables part integrity to stablize；2, sealing effect is good, and has saved the working hour of artificial stickup sponge, improves dress
Stability with efficiency and product；3, the surface that rubber air door is contacted with plastic casing requires to coat lubricant grease, prevents rubber
Frictional force is too big between glue material and plastic casing, leads to air door clamping stagnation；4, the rubber air door and plastics of lubricant grease will be coated with
Shell is assembled together, it is ensured that the annular lug on plastic casing is assemblied in annular seal groove；It is closed when rubber air door is in
When state, two rubber seal muscle on rubber seal side are fitted closely with plastic casing, lift-off seal effect.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments；
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is cross section structure figure of the invention；
Fig. 3 is air door structure schematic diagram in the present invention；
In FIG. 1 to FIG. 3,1, air door ontology；2, air door sealing edge；3, cantilever arm；5, annular wall；6, shell；7, annular
Seal groove；8, annular lug；9, sealing bar；10, clamping wall.
