Description
Technical field
The utility model relates to a kind of stop quick-release pin, particularly about a kind of quick-release pin with auto-lock function.
Background technique
Can a lot of situations need the connection of quick mounting or dismounting in the mechanical structure, especially for military use product, for reducing the mounting or dismounting time, raising the efficiency, realize that mounting or dismounting are crucial technical orders fast.The quick-release pin is a kind of very practical coupling, and it is widely used in the connection between component in the various mechanical structures.
The quick-release pin that prior art has locking function mainly contains spring stop pin, quick-release spring pin, stop quick-release pin, and its structure mainly contains shank, chock, spring, ring formation, and has formed industry standard and seriation.Pull the attachment hole that passes after chock makes itself and shank in alignment between component during use, pull down chock again, chock and ring play restriction and move and the effect of stop like this.
Yet the chock of the quick-release pin of prior art is semi-circular sheet, and thickness 1.5～4mm requires great effort when pulling chock in the use, and the bite phenomenon easily takes place, and practicability is not good enough.Particularly, after using a period of time, chock gives birth to embroidery, more difficult pulling.Also have, the chock of existing quick-release pin does not have auto-lock function.
The model utility content
The utility model purpose is: pull effort, easily bite, no auto-lock function, problem that practicability is not good enough in order to solve prior art quick-release pin, the utility model provide a kind of light laborsaving, auto-lock function, the good self-locking stop quick-release pin of practicability arranged.
In order to solve the problems of the technologies described above, the technological scheme that is provided is as follows: a kind of self-locking stop quick-release pin comprises shank, spring, push rod, chock, rivet, wherein, described shank one end is " protruding " font and seamed edge rounding, there is a chock on " protruding " font top of shank, be hinged between described chock and the shank, be provided with groove in the chock, there is a hole at this groove center, be provided with a pressure spring in the hole, pressure spring and shank " protruding " font has a push rod between the top, and the center and the both sides on described shank " protruding " font top are provided with the several balls connected in star.
The end that described shank does not connect chock is connected with ring by a through hole.
The center and the both sides on described shank " protruding " font top are provided with 3 ball recess.
Link to each other by rivet between described chock and the shank.
Wherein, described push rod can be free to slide about on the smooth hollows that shank " protruding " font top seamed edge falls.Push rod in chock slips into ball recess, and chock promptly enters the self-locking stop position.
The utility model beneficial effect is: the quick-release pin that is different from prior art, the utility model self-locking stop quick-release pin has in 3 ball recess by center and the both sides that the pressure spring in the chock groove promotes the embedded shank of push rod " protruding " font top, realizes the stop locking.When the push rod in the chock slips in the central spherical groove on shank " protruding " font top, chock is locked, and this moment, chock and shank were in alignment, and the convenient quick-release pin of realizing inserts and extracts; When the push rod in the chock slips in the ball recess of shank " protruding " font both sides, chock is locked, and this moment, ring and chock limited moving axially of coupled component.And it is because chock is cylindrical, so convenient and strength-saving when pulling.In addition, the push rod of chock can be free to slide about on the smooth hollows that shank " protruding " font top seamed edge falls, so be difficult for bite.Therefore the utility model self-locking stop quick-release pin is convenient, laborsaving, and has auto-lock function, thus efficient, practical, performance is safe and reliable, be highly suitable for being connected between two layers of floor of aircraft and aircraft support equipment component.

Schematic representation when Fig. 3 is a kind of self-locking state of the utility model self-locking stop quick-release pin one better embodiment;
Wherein, 1-ring, 2-shank, 3-spring, 4-push rod, 5-chock, 6-rivet.
Embodiment
The utility model is described in further detail below by embodiment:
Please consult Fig. 1 and Fig. 2 simultaneously, it is respectively the structural representation and the partial sectional view of the utility model one better embodiment.The utility model self-locking stop quick-release pin comprises ring 1, shank 2, spring 3, push rod 4, chock 5, rivet 6.Wherein, described shank 2 tops are " protruding " font and seamed edge rounding, and end has through hole, and ring 1 is enclosed within the through hole of shank 2 ends.There is a cylindrical chock 5 on " protruding " font top of described shank 2, is hinged between chock 5 and the shank 1, links to each other by rivet 6 riveted joints, to guarantee the rotation of chock 5.There is a hole at described chock 5 groove centers, are provided with a pressure spring 3 in the hole, are provided with a push rod 4 between pressure spring 3 and shank 2 " protruding " the font top.Wherein, the center and the both sides on described shank " protruding " font top have 3 ball recess, and the push rod in chock slips into any ball recess, and chock 5 promptly enters the self-locking stop position.
In the groove center hole that the pressure spring of the utility model self-locking stop quick-release pin and push rod are embedded in chock, the pressure spring and the push rod that are different from quick-release pin in the prior art are embedded in the shank, chock has been a thin slice no longer just like this, and is designed to cylindrical.In addition, the push rod of chock can be free to slide about on the smooth fillet that shank " protruding " font top seamed edge falls, so convenient and strength-saving when pulling, be difficult for bite.
Please consult Fig. 1 and Fig. 3 simultaneously, Fig. 1 and Fig. 3 are the utility model self-locking states.When the utility model self-locking stop quick-release pin uses, pull chock push rod is slipped in the central spherical groove on shank " protruding " font top, chock is locked, and chock and shank are in alignment, in the connecting hole between quick-release pin insertion part.Pulling down chock again slips in the ball recess of any side in shank " protruding " the font both sides push rod, chock is locked, chock and shank angle 90 degree, this moment, ring and chock limited moving axially of coupled component, and the installation connection work between component is finished.In like manner, during the dismounting component, pull chock push rod is slipped in the central spherical groove on shank " protruding " font top, chock is locked, and chock and shank are in alignment, and the quick-release pin is transferred to the connecting hole between part, and this moment, dismantlement work was finished.
In sum, the utility model self-locking stop quick-release pin is convenient, laborsaving, and has auto-lock function, so efficient, practical, performance is safe and reliable, have bigger use value, now be widely used in being connected between two layers of floor of aircraft and aircraft support equipment component.
