Description

The tapered end of band idle-run lock pin
Technical field
The utility model belongs to mechanical lock, relates to the tapered end that a kind of lock core can dally.
Background technology
Chinese patent ZL200710035717.X document discloses the tapered end that a kind of lock core can dally.This tapered end comprises the lock core in lock body, the lock body, lock core and rear lock core before lock core is divided into, be provided with the locking side column and the sliding shoe that can match in the locking side column groove on the preceding lock core with the lock core marble groove, be respectively equipped with the projection (groove) and the groove (projection) that can cooperate on sliding shoe and the locking side column, be provided with the locking side column back-moving spring between locking side column and the sliding shoe, between the end wall of sliding shoe and locking side column groove, be provided with the sliding shoe back-moving spring; With the corresponding lock pin chute that is provided with of locking side column groove of preceding lock core, the lock pin chute has an end wall at the afterbody of rear lock core on rear lock core, places lock pin in the lock pin chute, and the lock pin back-moving spring is set between end wall in the lock pin chute and the lock pin; The elasticity of lock pin back-moving spring is greater than the sliding shoe back-moving spring; Have at least one to adopt the inclined-plane to contact in lock pin or the locking side column groove with another; Be provided with the step that is used for the rear lock core stop bit at the lock body afterbody, on this step with the corresponding breach that has of the lock pin chute on the rear lock core, lock pin can match with this breach, also be provided with the spacing breach of restriction rear lock core rotational angle on this step, the afterbody of rear lock core is provided with the projection that matches with lock body afterbody upper limit breach.Because the preceding lock core of this tapered end can dally, external force can't act on lock body or rear lock core by preceding lock core, and the reasonable brute force that solved is unblanked and a destructive difficult problem of unblanking.Unblank very effective to preventing violent tool sled twistlock core.But find that in manufacture process also there are some problems in this tapered end: mainly be that structure is complicated, component are more, and processing time consuming, machining accuracy are difficult to guarantee that cost is higher.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of structure more simply with the tapered end of idle-run lock pin.
The utility model purpose is achieved in that the tapered end of band idle-run lock pin, comprise the preceding lock core in the lock body, be provided with the locking side column that can match in the locking side column groove on the preceding lock core with the lock core marble upper groove, locking side column is provided with step-like groove, the top of locking side column groove is provided with and locking side column card and the fixed part that the scalariform groove matches of appearing on the stage, between fixed part and locking side column, be provided with radially back-moving spring of locking side column, between the end wall of locking side column and locking side column groove, be provided with the axial back-moving spring of locking side column.
Described fixed part both can be a lock core upper stop piece before being embedded in, and also can be the sleeve on the lock core before being enclosed within.
The relative prior art of the utility model, cancelled sliding shoe, only kept locking side column, by matching with card on the preceding lock core in that step-like groove is set on the locking side column, reaching the control locking side column is unblanking or axially-movable during blocking, realize the clutch of front and back lock core, lock core can dally before making.This structure makes lock head structure simpler, and component reduce, and easier processing can further reduce cost.
Further specify technical solutions of the utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial top view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Fig. 4 is the different user mode schematic diagrames of Fig. 1.
Fig. 5 is the partial top view of Fig. 4.
The different fixing block diagram on the top of lock core locking side column groove before Fig. 6 is provided in a side of.
The specific embodiment
See Fig. 1 to Fig. 3, the tapered end of band idle-run lock pin, comprise lock body 2, lock core in the lock body 2, lock core 1 and rear lock core 14 before lock core is divided into, be provided with the locking side column 6 that can match in the locking side column groove on the preceding lock core 1 with lock core marble upper groove 15, locking side column 6 is provided with step-like groove 7, the top of locking side column groove is provided with and locking side column card 8 and the fixed part that scalariform groove 7 matches of appearing on the stage, sleeve 3 before fixed part adopts and is enclosed within on the lock core, be provided with radially back-moving spring 5 of locking side column between sleeve 3 and the locking side column 6, between the end wall of locking side column 6 and locking side column groove, be provided with the axial back-moving spring 4 of locking side column; On rear lock core 14 with the corresponding lock pin chute 13 that is provided with of locking side column groove in the preceding lock core 1, lock pin chute 13 has an end wall 12 at the afterbody of rear lock core, place lock pin 9 in the lock pin chute 13, between end wall 12 in lock pin chute 13 and the lock pin 9 lock pin back-moving spring 10 is set; The elasticity of lock pin back-moving spring 10 is greater than the axial back-moving spring 4 of locking side column; Lock pin 9 adopts inclined-plane 16 (referring to Fig. 2) to contact with the locking side column cell wall; Be provided with step 17 at lock body 2 afterbodys with rear lock core 14 stop bits, on the step 17 with the lock pin chute 13 corresponding breach 11 of opening, lock pin 9 in the lock pin chute 13 can match with this breach 11, also be provided with the spacing breach 18 of restriction rear lock core 14 rotational angles on this step 17, the afterbody of rear lock core 14 is provided with the projection 19 that matches with lock body 2 afterbody upper limit breach 18.
Described fixed part also can adopt the catch 3 ' on the lock core before being embedded in, as shown in Figure 6.
The operating principle of the utility model tapered end: locking states is seen Fig. 4, and card 8 is positioned at getting out of a predicament or an embarrassing situation of locking side column 6 upper grooves 7.When unblanking, see Fig. 1, inserting key 20 arranges lock core marble upper groove 15 in order, while locking side column radially back-moving spring 5 makes radially inwardly motion of locking side column 6, card 8 is positioned at topping bar of locking side column 6 upper grooves 7, locking side column 6 can axially-movable, locking side column groove before the preceding lock core 1 of rotation aligns the lock pin 9 in the rear lock core 12 in the lock core 1, because the elasticity of lock pin back-moving spring 10 is greater than the axial back-moving spring 4 of locking side column, lock pin 9 with the locking side column in the locking side column groove 6 in sinciput is gone forward side by side the locking side column groove, at this moment front and back lock core 1,14 fuse by lock pin 9, and preceding lock core 1 relative rear lock core 14 can not dally; During locking, earlier preceding lock core 1 is rotated an angle, see Fig. 5, because lock pin 9 adopts inclined-plane 16 to contact (referring to Fig. 2) with the locking side column cell wall, the locking side column cell wall forces in the lock pin 9 withdrawal rear lock cores 14, locking side column 6 axially resets, at this moment card 8 aligns with locking side column 6 getting out of a predicament or an embarrassing situation of upper groove 7, extract key 20 out, see Fig. 4, the lock core marble lack of alignment, groove 15 on the lock core marble forces locking side column 6 radially outward to be moved, and card 8 enters and makes locking side column 6 location in the getting out of a predicament or an embarrassing situation of locking side column 6 upper grooves 7, and at this moment locking side column 6 just is in front and back two lock cores 1 with the end face that contacts between the lock pin 9,14 interface, preceding lock core 1 relative rear lock core 14 can relatively rotate, and realizes idle running.
