Description
Technical field
The utility model is related to a kind of cam-type connection fasteners.
Background technology
Screw bolt and nut is chiefly used in the fastening of the connection between two connected pieces, such as the connection between two ring flanges,
Although relatively stable reliable using screw bolt and nut connection, dismounting is particularly troublesome, when especially quantity is more, needs to spend
The more time removes nutting, less efficient.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of structure novel, cam-type connection fastening easy to use
Device.
The utility model is realized using following scheme：A kind of cam-type connection fastener, including to pass through two quilts
The connection axis pin that connector links together two connected pieces, one end of the connection axis pin, which is provided with, to be stuck in two and is connected
The head of fitting side, the connection axis pin other end are provided with the cam for making two connected pieces compress.
Further, the cam is two and is symmetricly set on connection axis pin both sides, and two cams pass through intermediate connecting shaft
It links together, is offered through the notch for connecting axis pin both sides and being passed through for intermediate connecting shaft on the connection axis pin.
Further, the protruding end of the cam is provided with positioning section.
Further, further include the spanner for pulling cam rotation, offer on the cam and be inserted into for spanner
Jack.
Compared with prior art, the utility model has the advantages that：The utility model cam-type connection fastening dress
It sets and is connected instead of traditional bolt and nut, two connected pieces are compressed using the protruding end of cam, connection is reliable close, and
It is easy to operate, it is easy to use, it is substantially shorter connected piece disassembly and assembly time, improves efficiency.
To make the purpose of this utility model, technical solution and advantage be more clearly understood, specific embodiment will be passed through below
And relevant drawings, the utility model is described in further detail.

Specific implementation mode
As shown in Fig. 1 ~ 4, a kind of cam-type connection fastener, including to pass through two connected pieces 100 by two
The connection axis pin 200 that connected piece links together, one end of the connection axis pin 200, which is provided with, is stuck in two connected pieces one
The head 210 of side, connection 200 other end of axis pin are provided with the cam 300 for making two connected pieces compress；Utilize the utility model
Cam-type connection fastener replaces traditional bolt and nut to connect, and two connected pieces are compressed using the protruding end of cam,
Easy to operate, easy to use, connection is reliable close, is substantially shorter connected piece disassembly and assembly time, improves efficiency.
In the present embodiment, the cam 300 is two and is symmetricly set on 200 both sides of connection axis pin, and two cams pass through
Intermediate connecting shaft 310 links together, and is offered on the connection axis pin 200 through connection axis pin both sides and for intermediate connecting shaft
310 notches 220 passed through, the notch band is gradient and its opening is tilted towards connected piece direction, intermediate after the completion of connection
Connecting shaft is by an opposition so that intermediate connecting shaft can be stuck in notch, to avoid intermediate connecting shaft from notch
Middle abjection ensures that connection is reliable and stable.
In the present embodiment, the protruding end of the cam 300 is provided with positioning section 320, and the lug boss of cam 300 passes through
It positions section 320 with connected piece to coordinate, avoids cam from rotating, keep reliable pressing force.
In the present embodiment, further including the spanner 400 for pulling the rotation of cam 300, spanner 400 is allen wrench,
The jack 330 for offering on the cam 300 and being inserted into for spanner, jack 300 are hexagonal hole, and the jack center line is in
Between connecting line axial line overlap.
Above-listed preferred embodiment has been further described the purpose of this utility model, technical solution and advantage,
It should be understood that the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this practicality
Within novel protection domain.
