Interconnecting piece is arranged in adjustable vane, one end of the adjustable vane, and the cross section of the interconnecting piece includes a pair of mutual
Parallel side；
Rocker arm, including the first rocker arm and the second rocker arm, first rocker arm is detachably connected with second rocker arm, in institute
It states and offers blade mounting hole between the first rocker arm and second rocker arm, the blade mounting hole is mutually fitted with the interconnecting piece
Match.
Optionally, the cross section of the interconnecting piece is in rectangle.
Optionally, first rocker arm is bolted with second rocker arm.
The utility model has the beneficial effects that the adjustable vane of the utility model and the connection structure of rocker arm, by by rocker arm
It is arranged to separate structure, it, can also be first by can even if the axis of adjustable vane interconnecting piece is not overlapped with the axis of rocker arm when assembly
It adjusts blade setting to be fixedly connected into rocker arm, then by the separate structure of rocker arm, completes assembly, realize no interference fit.
Detailed description of the invention
The drawings herein are incorporated into the specification and forms part of this specification, and shows and meets the utility model
Embodiment, and be used to explain the principles of the present invention together with specification.
Fig. 1 is the connection structure general illustration of prior art adjustable vane and rocker arm；
Fig. 2 is the connection structure general illustration of the utility model adjustable vane and rocker arm.
Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.
As shown in Fig. 2, the adjustable vane of the utility model and the connection structure of rocker arm, comprising: adjustable vane 1, rocker arm 2.
Specifically, interconnecting piece is arranged in one end of adjustable vane 1, the cross section of the interconnecting piece includes a pair of is parallel to each other
Side；Rocker arm 2 includes the first rocker arm 21 and the second rocker arm 22, and the first rocker arm 21 is detachably connected with the second rocker arm 22, shakes first
Blade mounting hole is offered between arm 21 and the second rocker arm 22, blade mounting hole is adapted with interconnecting piece.
Advantageously, the interconnecting piece of adjustable vane is arranged to rectangular shape in the present embodiment, cross section is in rectangle,
In the blade mounting hole for being preferably connected to rocker arm 2 when adjustable vane 2 rotates.
Advantageously, the first rocker arm 21 and the second rocker arm 22 can be bolted, be blocked by a variety of dismountable connection types
Button connection etc., in the present embodiment, preferably the first rocker arm 21 and the second rocker arm 22 are bolted.
Rocker arm 2 is arranged to the first rocker arm 21 and second and shaken by the adjustable vane of the utility model and the connection structure of rocker arm
22 two parts of arm, when adjustable vane 1 and rocker arm 2 assemble, first by the company between the first rocker arm 21 of rocker arm 2 and the second rocker arm 22
Connecting bolt loosens, and the blade mounting hole between the first rocker arm 21 and the second rocker arm 22 is made to become larger, then by the interconnecting piece of adjustable vane 1
It is placed into the blade mounting hole between the first rocker arm 21 and the second rocker arm 22, after position is adjusted, then by the first rocker arm 21
It is tightened with the connection bolt of the second rocker arm 22.
The adjustable vane of the utility model and the connection structure of rocker arm are assembled by the way that rocker arm 2 is arranged to separate structure
When, even if the axis of 1 interconnecting piece of adjustable vane is not overlapped with the axis of rocker arm 2, adjustable vane 1 first can also be installed to rocker arm
In 2, assembly is completed, no interference fit is realized.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
