Description

Cylinder padlock

The utility model relates to a kind of lock, particularly a kind of spring padlock.

Spring padlock is widely used in people's daily life, go out to provide many convenience to people, but it comes with some shortcomings still; After lock was opened, key can arbitrarily be extracted out, often causes key to be locked indoor, need look about key when perhaps laying the key under the door.Key back locking need be pried open door and take key when indoor, seeks key and need spend the regular hour, influences people's operate as normal, study and life; In addition, its head wore and tore after the horizontal bolt of spring padlock used a period of time, can't lock hook, and lock is easy to pry open, and working life shortens.

The purpose of this utility model is to provide a kind of spring padlock that key can not be extracted out when locking of opening, and can continue to use after horizontal bolt wearing and tearing.

The purpose of this utility model realizes in the following manner: it comprises lock body, lock core, horizontal bolt and link, on lock body, be positioned at link rotating shaft end one side warp-wise pellet shot from a slingshot hole is arranged, installing pellet shot from a slingshot in it, corresponding link rotating shaft end inboard and lock core excircle place have inclined-plane notch and recess respectively.There is the stopper slot of disconnection link rotating shaft end end, prevents that link from rotating 360 ° around the shaft.

The utility model improves on original spring padlock a little, and the back key of avoiding fully unblanking separates with lock, can prolong the application life of lock simultaneously effectively, is a kind of desirable spring padlock.

Accompanying drawing has provided an embodiment of the present utility model:

Structural representation when Fig. 1 shuts for the utility model;

Fig. 2 for the utility model unblank the back structural representation;

Fig. 6 for the utility model unblank the back vertical view.

The utility model is described in further detail for the contrast accompanying drawing below.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 6, this lock is improved to form on original double hook spring padlock, spring padlock is made up of lock body 8, lock core 5, horizontal bolt 3,7 and double hook link 2, on lock body 8, be positioned at link 2 rotating shaft ends one side radially pellet shot from a slingshot hole 1 is arranged, installing pellet shot from a slingshot 4 in it, corresponding link 2 rotating shaft end inboards and lock core 5 excircle places have inclined-plane notch 14 and recess 15 respectively.When unblanking, insert lock core 5 pellets shot from a slingshot 9 with key 11 and move, compression spring 10, when key 11 rotates about 30 °, horizontal bolt 3 and 7 is 6 compressions of retraction spring in lock core, spring 16 elongations, and the top is opened link 2 and upwards is moved to maximum position, newly-increased pellet shot from a slingshot 4 withdraws from from link 2 ramp notches 14, in withdrawing from notch 14 fully, at this moment, under link 2 outer circumference surface effects, pellet shot from a slingshot 4 is headed in the recess 15 of lock core 5, pellet shot from a slingshot 4 sticks lock core 5 it can not be resetted like this, and key 11 can not taken out.For recess 15 backs of avoiding pellet shot from a slingshot 4 to withdraw from lock core 5 enter in the link 2 rotating shaft end breach, present embodiment changes rotating shaft end breach into outside breach 13 by former inboard place, horizontal bolt 12 correspondences are loaded on the outside, for preventing that link 2 from rotating around the axis 360 ℃ pellet shot from a slingshot 4 is entered in the breach 13 after unblanking, the annular stop groove of link 2 roller end is changed into the stopper slot 17 of disconnection, it is made up of two sections straight troughs and one section arc groove, show as Fig. 5, like this under horizontal bolt 12 effects, link 2 can only respectively change 90 ° and avoid pellet shot from a slingshot 4 to withdraw from recess 15 back of lock core 5 and enter in the link 2 rotating shaft end breach 13 around about axle, when shutting, when pressing link 2 declines to put in place, horizontal bolt 3 in the lock body 8,7 two springs, 6 elongations, head on horizontal bolt 3 on the one hand, 7 enter respectively in the hook groove of link 2, make lock core 5 revolutions until putting in place on the other hand, pellet shot from a slingshot 4 is sliding withdrawing from the recess 15 of lock core 5, headed in the notch 14 that enters link 2 by lock core 5 outer circumference surfaces until withdrawing from recess 15 fully, at this moment, key can be extracted out.After lock used a period of time, when horizontal bolt 3 and 7 head were worn, pellet shot from a slingshot 4 wearing and tearing were very little, and this moment, pellet shot from a slingshot 4 can play the effect of horizontal bolt 3, can prolong the application life of lock.
