The failure that door can not be opened, and the fixed apparatus parts of existing air valve bridge are more, assembly is complicated, and practicability is not strong.
Utility model content
The utility model provides the connection fit structure of a kind of air valve bridge and rocker arm regarding to the issue above, the air valve bridge and shakes
The connection fit structure of arm can prevent air valve bridge from rotating, and structure is simple.
In order to solve the above-mentioned technical problem, the utility model provides the connection of a kind of such as air valve bridge and rocker arm of flowering structure
The middle part of fit structure, including rocker arm ontology, rocker arm ontology is equipped with rocker shaft hole, is structurally characterized in that: on the rocker arm ontology
Equipped with one side of rocker shaft hole and spaced two boss is located at, sliding chamber, the air valve bridge and rocker arm are formed between two boss
Connection fit structure further include air valve bridge ontology, the side of the air valve bridge body upper part be equipped with can protrude into it is sliding intracavitary and can edge
The mobile inserted block of sliding chamber.
The top of the air valve bridge ontology is equipped with screw hole, and the inserted block includes the section that is spirally connected with screw hole cooperation, and be spirally connected section
Top upwardly extends the plug to be formed with sliding chamber cooperation.
The height of boss is gradually lower from middle part to two sides.
Boss along rocker arm ontology length direction setting and with this body by integral forming of rocker arm.
One side of the rocker arm ontology is equipped with adjusting screw, and the middle part of the air valve bridge ontology is inserted equipped with air valve bridge guide rod
Hole is equipped with cock body in air valve bridge guide rod jack, and the adjusting screw is contacted with the upper surface of cock body.
The lower part of the adjusting screw is equipped with link block, and link block is equipped with the ball from its upper surface to its internal stretch
Nest, the lower end of the adjusting screw are equipped with the bulb cooperated with ball-and-socket.
It has the advantage that and first inserted block is installed in screw hole compared with prior art using the above structure, assemble rocker arm
It is when ontology that inserted block insertion cunning is intracavitary.Camshaft actuated adjusting screw moves down, and adjusting screw drives air valve bridge ontology downward
The arc-shaped swing of rocker arm ontology is also driven while mobile, allows for inserted block in this way in the intracavitary sliding of cunning, and inserted block is with valve
Bridge ontology also moves down while moving down, and the shallow middle part in the depth two sides for sliding chamber is deep, allows for inserted block so always in sliding chamber
It is interior, it prevents from coming off, inserted block can thus be sent out during moving down in the intracavitary realization guide and limit of cunning to avoid air valve bridge ontology
Raw rotation.
In conclusion the utility model can prevent air valve bridge from rotating, and structure is simple, avoids increasing components.

Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing:
As shown in figures 1-6, the connection fit structure of air valve bridge and rocker arm provided by the utility model, including rocker arm sheet
Body 1, the middle part of rocker arm ontology 1 are equipped with rocker shaft hole 11, and rocker arm ontology 1 is equipped with positioned at 11 1 side of rocker shaft hole and interval is set
Two boss 12 set, two boss 12 are arranged in parallel in the present embodiment, and sliding chamber 13, the height of boss 12 are formed between two boss 12
It is gradually lower from middle part to two sides, the depth two sides for allowing for sliding chamber 13 in this way are shallow intermediate deep.Boss 12 is along shaking in the present embodiment
The length direction of arm body 1 is arranged and is integrally formed with rocker arm ontology 1.The connection fit structure of the air valve bridge and rocker arm further includes
Air valve bridge ontology 2, the side on 2 top of air valve bridge ontology are equipped with the inserted block 3 that can be protruded into sliding chamber 13 and can move along sliding chamber 13, gas
The top of raft of pontoons ontology 2 is equipped with screw hole, and inserted block 3 includes the section that is spirally connected with screw hole cooperation, and the top for the section that is spirally connected upwardly extends to be formed
The plug cooperated with sliding chamber 13, the plug be it is rectangular, put between shape plug and the inner wall of sliding chamber 13 that there are slidable gap, sides
Shape plug, which is inserted into sliding chamber 13, can be realized limit, so that air valve bridge ontology 1 be avoided to rotate when moving down.
As shown in Figure 1, a side of rocker arm ontology 1 is equipped with adjusting screw 14, the middle part of air valve bridge ontology 2 is equipped with air valve bridge
Guide rod jack is equipped with cock body 21 in air valve bridge guide rod jack, and adjusting screw 14 is contacted with the upper surface of cock body 21.Adjusting screw
14 lower part is equipped with link block 15, and link block 15 is equipped with the ball-and-socket from its upper surface to its internal stretch, adjusting screw 14
Lower end is equipped with the bulb cooperated with ball-and-socket, and for bulb by being installed in ball-and-socket, the fit structure of bulb and ball-and-socket is existing
There is technology, details are not described herein, and bulb can change direction in ball-and-socket in the structure, is conveniently adjusted screw 14 and applies to cock body 21
It presses and moves down air valve bridge ontology 2.Matching relationship in the present embodiment between adjusting screw 14 and cock body 21 is existing skill
Art, detailed construction and action process repeat no more.
Inserted block 3: being first installed in screw hole by the use process of the utility model when assembly, will insert when assembling rocker arm ontology 1
Block 3 is inserted into sliding chamber 13.Camshaft actuated adjusting screw 14 moves down, which is the prior art, no longer superfluous herein
It states, adjusting screw 14 drives air valve bridge ontology 2 also to drive the arc-shaped swing of rocker arm ontology 1 while moving down, and thus makes
Inserted block 3 slides in sliding chamber 13, and inserted block 3 is moved down with air valve bridge ontology 2 while, also moves down, and slides the depth of chamber 13
It is deep to spend the shallow middle part in two sides, allows for inserted block 3 in this way and is sliding in chamber 13 always, prevent from coming off, inserted block 3 realizes guiding in sliding chamber 13
Limit, can thus rotate during moving down to avoid air valve bridge ontology 2.
The above is the specific constructive form of the utility model, and the present utility model is not limited to the above embodiments,
For those skilled in the art, equivalent variations and part replacement based on specific structure on the utility model are all practical new at this
