The model utility content
The utility model is in order to solve the technological deficiency that end wear is fast and assembling takes up room that existing connecting pin exists, a kind of connecting pin that can quick-acting and quick-discharging is provided, connecting pin is hidden fully in the inside of its connected element, make joint more compact structure and the working life of effectively improving connecting pin.
The utility model adopts following technological scheme to realize above technical purpose: a kind of quick-acting and quick-discharging connecting pin comprises bearing pin 1, spring 2, steel ball 3 and pin cap 4; Bearing pin 1 one end outer surfaces are provided with step, be provided with a through hole 5 that intersects with described bearing pin axis normal at described bearing pin 1, be provided with a blind hole 6 at the end face upper edge of bearing pin 1 the other end bearing pin axis and be communicated with described through hole 5, the bottom surface of described blind hole 6 extends to the axis of crossing described through hole 5; In through hole 5, be provided with a spring 2, described spring 2 two ends contact a steel ball 3 respectively, the diameter of described steel ball 3 is greater than the diameter of described through hole 5, and steel ball 3 has less than half spheroid and exposes the outer round surface that through hole 5 and its arc toplap go out bearing pin 1 under spring 2 pushing tows; Pin cap 4 is inserted into the end of blind hole 6, is encapsulated in spring 2, steel ball 3 in the through hole 5 and realizes the radial location of spring 2, steel ball 3.
As preferred version of the present utility model, described blind hole 6 is cone shape hole, and described pin cap 4 adopts conical surface to lock with blind hole 6.
Be provided with the circular groove that mates with spring 2 at described pin cap and realize the radial location of described spring in through hole.
In the utility model, the 1/3-3/4 of described steel ball 3 hemisphere exposes through hole 5.
The utility model is by advancing pin-and-hole with the direct plug-in mounting of the bearing pin of connecting pin, one end is located by step, the other end cooperates by the interior round wall of the steel ball in the through hole and pin-and-hole realizes the axial restraint of connecting pin in pin-and-hole, steel ball and spring assemble on the axis that is arranged on through hole from blind hole, because the slightly larger in diameter of steel ball is in the diameter of through hole, steel ball props up the intersecting line location of through hole and blind hole, spring places the restriction that is subjected to through hole and pin cap in the through hole, realize radial location, the elastic force of spring is with bearing pin axially locating in pin-and-hole by compression for the part that steel ball exposes bearing pin, and the utility model is applicable to that the little pin of axially loaded connects.The steel ball and the spring that are arranged in the bearing pin all can use standard piece, are convenient to purchase.
In the utility model, bearing pin is hidden fully in the inside of its connected element, more compact structure, and bearing pin can not be worn, and makes the bearing pin longer service life; Moreover, only need during assembling directly to insert and extract out, need not again assembling in addition or dismantle annex such as cotter pin, make assembling place compact structure, saved installation time and space, dismounting is faster.
