Abstract

The utility model relates to an anti-drop guide pin, comprising an inserting rod, a handle connected with the inserting rod, an anti-drop end, a guide end and a locking end, which are connected mutually in order; arc transition is formed on each connection part, and the whole body is in an integrated structure. With the adoption of the structure, an anti-drop pin can be rapidly mounted and the following problems in the prior art are solved: the anti-drop pin is mounted by manually breaking apart the anti-drop end, is complex in operation and difficult to process, and even hurts hands of a user.

Description

The guiding locking pin

Technical field

The utility model relates to a kind of pin, relates in particular to a kind of guiding locking pin.

Background technique

In bindiny mechanism with bearing pin, deviate from for preventing bearing pin, generally a pin shaft hole need be set in the end of bearing pin; In pin shaft hole, insert cotter pin then; Need the end of cotter pin be broken into two with one's hands when cotter pin is used, in dismounting, again the end of cotter pin broken off with the fingers and thumb directly.Such structure installation and removal all need instrument; Make troubles to the user, and generally all can not re-use after having torn open, when installing again; Also need be equipped with and the original the same cotter pin of specification, cause the wasting of resources and the efficient that reduces installation and removal like this.

A kind of locking pin is arranged now, by inserted link, anti-press-off, anticreep end, anti-off-clip, bending etc. constitute, and wholely become plane, mainly utilize inserted link and the anti-realization anticreep of press-offing.But before inserted link is inserted into the pin-and-hole of bearing pin end, also must break anti-press-offing earlier into two with one's hands, also will break anti-press-offing during dismounting earlier into two with one's hands, this structure operation is got up loaded down with trivial details, also can hurt hand sometimes; Moreover anti-diameter of press-offing is difficult to processing like this less than the diameter of anticreep end; If often mounting or dismounting are prone to cause the distortion of protecting cover and anticreep end, it is not firm to lock; Break protecting cover at last off with the fingers and thumb, when inserting inserted link, be not easy disposable being in place.

Summary of the invention

The utility model technical problem to be solved provides the locking pin that a kind of ability quick mounting has guiding, and processing technology is simple, and is easy to operate, and the dismounting back is reusable.

The technological scheme that its technical problem of the utility model solution is taked is: a kind of guiding locking pin, comprise inserted link and the handle and the anticreep end that are connected with inserted link, and the anticreep end is connected with guide end, and the other end of guide end links to each other with the locking end.

In order conveniently to break the purpose that can reach installation off with the fingers and thumb without hand; Described guide end and locking end and inserted link are not in one plane; And with each structure of inserted link at an angle; Angle is 15 °～60 °, and further described angle is 40 °～50 °, and further preferred version is: described angle is 45 °.

In order to make locking pin not hinder hand when in use and also can not scratch bearing pin, described locking pin is structure as a whole, and arc transition is all adopted in the joint of each section.

Concrete: described anticreep end is curved, the lock shaft of can better fitting; The end of described locking end and the distance of inserted link can better reach the effect of locking less than the distance of the peak and the inserted link of anticreep end; Described guide end is the initial end points of inserted link with the tie point of locking end and the vertical point of inserted link; The diameter of section of described each constituent element of locking pin is identical.

The beneficial effect of the utility model is: inserted link, handle, anticreep end, guide end and locking end are structure as a whole, and need not assemble separately, need not break the anticreep end into two with one's hands during use; Only need hand-held handle; Just can be easy to make inserted link to be inserted into the pin-and-hole the inside of bearing pin through inserted link, guide end and locking end, and be clamped in the anticreep end, improve the efficient of installation and removal; Moreover can select the locking pin of different size according to the diameter of axle of bearing pin, lock more firm like this.The joint of this structure is circular arc and connects, and so not only locks bearing pin easily, and can not scratch bearing pin.Such structure can quick mounting, and can reuse after the dismounting, improves recycling rate of waterused.End that also has the locking end and the distance of the distance of inserted link less than peak and the inserted link of anticreep end can prevent once more that like this bearing pin from deviating from from inserted link, and this structure are processed easily and are operated.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the 3 dimensional drawing of the utility model.

Among the figure: 1, inserted link; 2, handle; 3, anticreep end; 4, guide end; 5, locking end.

Embodiment

A kind of guiding locking pin as depicted in figs. 1 and 2, the handle 2 and anticreep end 3 that comprise inserted link 1 and be connected with inserted link 1, anticreep end 3 is connected with guide end 4, and the other end of guide end 4 links to each other with locking end 5, and each constituent element connecting place all adopts arc transition.Inserted link 1, handle 2 and anticreep end 3 are a plane structure; Guide end 4 and locking end 5 and inserted link 1 be not all a plane structure; Guide end 4 has a certain degree with inserted link 1 each structure with locking end 5, and this angle is 45 °, and guide end 4 is the initial end points of inserted link 1 with the tie point of locking end 5 and the vertical point of inserted link 1; The end of locking end 5 and the distance of inserted link 1 are less than the distance of the peak and the inserted link 1 of anticreep end 3, and the diameter of section of each constituent element of locking pin is identical.

Choose the guiding locking pin of anticreep end with suitable diameter; Hand-held handle 2 under both guiding of guide end 4 and locking end 5, is inserted into inserted link 1 in the pin-and-hole of bearing pin; And be clamped in the anticreep end 3; So just prevent that bearing pin from deviating from, also have the radius of the distance of locking end 5 and inserted link 1, play the effect that prevents that once more bearing pin from deviating from from inserted link 1 like this less than bearing pin; When dismantling, hand-held handle 2, another hand are broken locking end 5 and anticreep end 3 into two with one's hands, and inserted link 1 is extracted out in pin-and-hole, promptly accomplish dismounting.
