Abstract
The utility model discloses a self-locking pin of a shackle. The center of the pin is provided with a hole, an ejector rod is arranged in the hole, the front of the ejector rod is wedged, the front end of the pin is crimped with a screw via an end cap, two wedged stoppers are inserted into stopper holes of the end of the pin oppositely and are tightened by a tension spring, a detachable pull rod which is thinner than the rear end of the ejector rod is fixed at the rear end of the ejector rod, a flange capable of being detachably inserted into the pin hole is fixed at the rear end of the pin, a guide shaft is in threaded connection to the flange and the pull rod after penetrating through a guide hole on the flange and a guide slot on the pull rod, and a spring which is limited between the ejector rod and the flange is sleeved on the pull rod. The shackle with the self-locking pin can be detached conveniently and quickly and can not be damaged, and the self-locking pin can be reused, realizes self locking and is safe and reliable.
Description
Technical field
The utility model relates to a kind of shackle bearing pin.
Background technique
The installation of shackle at present has three kinds of forms usually with tightening: 1, use nut to be connected; 2, the direct tapping of shackle body makes bearing pin directly be screwed into shackle; 3, use cotter pin.Need earlier bearing pin is penetrated shackle body to the other end when no matter using the shackle bearing pin of which kind of form to install, nut is screwed tightening or slotting cotter pin tightening again, or directly be screwed into the shackle body tightening, all need certain tightening time, dismounting also is like this.This is one of steps necessary of present shackle installation, and according to the difference of tightening mode, the tightening time of use is also different.
Summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, and a kind of auto lock shackle bearing pin that does not need the tightening time is provided.
For addressing the above problem, technical solution of the present utility model is: a kind of auto lock shackle bearing pin, and it comprises end cap, block, bearing pin, push rod, pull bar, spring, the axis of guide, extension spring and flange; The center of bearing pin has the hole, and push rod is arranged in the hole, and the push rod front portion is a wedge shape, and the bearing pin front end is by end cap and screw crimping, and the wedge shape of two wedge-shaped catch and push rod head is complementary, and two blocks insert in the block hole of bearing pin end relatively, between strain by extension spring; The push rod rear end is fixed with dismountable pull bar thinner than push rod rear end, the bearing pin rear end is fixed with dismountable flange that stretches in the pin shaft hole, pilot hole is arranged on the flange, have the long strip guiding groove on the pull bar, the axis of guide is through in pilot hole and the guiding groove, is with spacing spring between push rod and flange on the pull bar.
The wedge shape of above-mentioned described push rod front portion is 45 °, 45 ° of the face tilts that block is complementary with it, and the wedge shape of push rod front portion is 45 ° with block and contacts.
The utility model shackle bearing pin is under free state, and push rod is spacing in end caps, ejects the both sides buting iron, and buting iron is wide to go out bearing pin; When the tension pull bar, push rod is removed end cap, and the both sides buting iron falls after rise by inclined-plane and push rod applying under the pulling of extension spring.Crossing up to falling after rise to the both sides buting iron, this moment, the both sides buting iron was less than the pin diameter size, like this, this bearing pin just can pierce into shackle body in the hole, after penetrating, releasing lever is under the effect of spring, the push rod return, by the inclined-plane buting iron is ejected, push rod is spacing in end caps, like this, bearing pin just be through shackle body in the hole, and finish bearing pin locking.When needing the dismounting shackle, the tension pull bar, buting iron falls after rise, takes out bearing pin and gets final product.The utility model dismounting shackle is convenient, fast, can not destroy shackle, can repeat again repeatedly to use, and auto lock, safe and reliable.
Description of drawings
Fig. 1 is an internal structure schematic representation of the present utility model.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
As shown in Figure 1, present embodiment comprises end cap 1, block 2, bearing pin 5, push rod 4, pull bar 7, spring 6, the axis of guide 9, extension spring 3 and flange 8.The center of bearing pin 5 has the hole, and push rod 4 is arranged in the hole, and push rod 4 front portions are 45 ° wedge shape, and bearing pin 5 front ends are by end cap 1 and screw crimping.45 ° of the face tilts that the wedge shape of block 2 and push rod 4 front portions is complementary, two blocks 2 insert in the block hole of bearing pins 5 ends relatively, between by extension spring 3 tensions, two wedge-shaped catch 2 are 45 ° with the wedge shape of push rod 4 heads and contact.Push rod 4 rear ends are fixed with the pull bar 7 thinner than push rod 4 rear ends by screw thread, bearing pin 5 rear ends are fixed with the flange 8 that stretches in the pin shaft hole by screw 10, on the flange 8 pilot hole is arranged, have the long strip guiding groove on the pull bar 7, the axis of guide 9 is through in pilot hole and the guiding groove, is with spacing spring 6 between push rod 4 and flange 8 on the pull bar 7.
Certainly, the utility model also has other multiple example, under the situation of the utility model spirit and essence, those of ordinary skill in the art can make corresponding change and distortion according to the utility model, the change of the gradient of the face that is complementary as the wedge shape of the wedge shape of push rod front portion and block and push rod front portion; Push rod rear end and pull bar, change of the means of fixation between bearing pin rear end and the flange or the like, but these corresponding changes and distortion all should belong to the improvement of equivalent technologies, belong to the protection domain of the utility model claim.
