Abstract
The utility model discloses included limit pin shafts, including the cylinder body of rod, the upper end of the cylinder body of rod has major diameter round end, the multi-diameter shaft that major diameter round end and the cylinder body of rod are structure as a whole, it is characterized by: the lower end surface setting limit baffle of the cylinder body of rod, limit baffle is fastened on the cylinder body of rod by screw, and when unclamping screw rotary spacing baffle, the outer for limiting baffle is converted from the outer round surface for entirely exceeding the cylinder body of rod without departing from the outer round surface of the cylinder body of rod to part.The utility model carries limit function, can carry out axial limiting to connected piece from the connected piece inner hole for being movably set in pin shaft outer circle, pin shaft is not exposed, has not only guaranteed that installation is beautiful but also can shorten pin shaft length, structure simply saves cost.
Description
Technical field
The utility model relates to a kind of fastener products, and in particular to a kind of pin shaft.
Background technique
Pin shaft is a kind of standardized fastener, both can static state be fixedly connected, can also do relative motion with connected piece, it is main
It is used for the hinged place of two parts, structure to be in the hinge connection.Pin shaft usually completes axial limiting, the axis of pin shaft with split pin locking
Cotter-pin hold will be arranged in end, and split pin will be installed on outside the inner hole of connected piece, so the length of the cylinder body of rod section of pin shaft
Degree is greater than the thickness of connected piece, neither can guarantee that installation is beautiful and not can be shortened pin shaft length, brings material consumption great achievement
This raising.
Summary of the invention
In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide the included limit function of one kind
Can, axial limiting can be carried out to connector from the connected piece inner hole of pin shaft outer circle is movably set in, not only guarantee installation it is beautiful but also
Length can be shortened, structure simply saves the included limit pin shaft of cost.
For this purpose, the utility model is realized using following scheme:
The upper end of included limit pin shaft, including the cylinder body of rod, the cylinder body of rod has major diameter round end, major diameter round end and circle
The multi-diameter shaft that mast body is structure as a whole, it is characterised in that: the lower end surface setting limit baffle of the cylinder body of rod, limit baffle are logical
It crosses screw to be fastened on the cylinder body of rod, when unclamping screw rotary spacing baffle, limits the outer of baffle from entirely without departing from circle
The outer round surface of mast body is converted between the local outer round surface beyond the cylinder body of rod.
Included limit pin shaft using the above structure, as long as opening up in the inner hole of connected piece first and limiting baffle thickness
And location matches or corresponding annular groove, then after pin shaft is packed into the inner hole of connected piece, rotary spacing baffle makes limiting block
The outer of piece locally exceeds the outer round surface of the cylinder body of rod, and the outer for limiting baffle at this time will locally enter annular groove
It is interior, axial limiting is carried out to connected piece.After adopting the above technical scheme, pin shaft can not expose to the interior of connected piece completely
Hole, therefore not only guaranteed that installation was beautiful but also can shorten pin shaft length, structure simply saves cost.
Preferably, the lower end surface of the cylinder body of rod is the step terrace of right low left high, the limit baffle is set to right
Rank terrace, limit baffle have elliptical profile, limit the intermediate of baffle and screw mounting hole is arranged.
Preferably, the vertical plane that right step terrace is connected with left step terrace is equipped with arc groove in central location, with fixed
Position outer locally exceeds the limit baffle of the external circular surfaces of cylindrical bar.Above-mentioned design can make limit baffle more preferably carry out limit arrive
Position limits reliably to realize.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the structural schematic diagram of utility model,
Fig. 2 is the bottom direction view of Fig. 1,
Fig. 3 is that limit baffle rotates the view after an angle of 90 degrees degree in Fig. 2.
Specific embodiment
As shown, the included limit pin shaft of the utility model, including the cylinder body of rod 1, the upper end of the cylinder body of rod 1 have big
Limit is arranged in the lower end surface of the multi-diameter shaft that diameter round end 2, major diameter round end 2 and the cylinder body of rod 1 are structure as a whole, the cylinder body of rod 1
Position baffle 5, limit baffle 5 is fastened on the cylinder body of rod 1 by screw 3, when unclamping 3 rotary spacing baffle 5 of screw, limiting block
The outer of piece 5 entirely exceeds the cylinder body of rod 1 without departing from the outer round surface of the cylinder body of rod 1 to part shown in Fig. 3 from shown in Fig. 2
Outer round surface between converted.Specific structure are as follows: the lower end surface of the cylinder body of rod 1 is the step terrace of right low left high, institute
It states limit baffle 5 and is set to right step terrace 4, limit baffle 5 has elliptical profile, and the intermediate setting screw of limit baffle 5 is installed
Hole, the vertical plane that right step terrace 4 is connected with left step terrace are equipped with arc groove 6 in central location, locally super to position outer
The limit baffle 5 of 1 outer round surface of the cylinder body of rod out.
