Abstract

The present invention discloses a vehicle lock which is mainly formed by pivoting components, such as a lock core rod, at least one connecting rod, a latch rod, etc., wherein one end of the lock core rod has a lock core insertion hole; the outer end of the latch rod is provided with a convex buckling tenon for inserting into the insertion hole in the lock core rod. The lock core rod, the connecting rod, the latch rod, etc. are pivoted and connected by connectors to form a vehicle lock, and the vehicle lock can be used for locking and buckling vehicle wheels when unfolded; when the vehicle lock needs folding, connectors are used as a pivot shaft, the lock core rod, the latch rod and the connecting rod are bent and folded; accordingly, the volume is reduced, and holding space can be saved.

Description

Lock

Technical field

The present invention relates to a kind of lock, a kind of bent folding particularly can be provided, the lock that reduce volume, conveniently places and can rapid deployment use.

Background technology

The structure of general U type lock 1 as shown in Figure 1, be provided with a U-shape lock bar 11 and a lock tube 12, wherein be made as eye-splice end 110 in U-shape lock bar 11 1 ends, supply corresponding to the lock core hole 120 on the lock tube 12, the lock core hole 120 of locking tube 12 when eye-splice end 110 insertions of U-shape lock bar 11 is the tool snap action, when desiring to trip, with the key turns core to remove snap close state, to take off U type lock 1 to eye-splice end 110; Yet though U type lock 1 can make things convenient at any time for snap close in wheel to reach thief-proof purpose, the structure of traditional U type lock 1: an integrated U-shape lock bar 11 and lock tube 12 integral body that constituted are placing, are taking up space when depositing.

Summary of the invention

The purpose of this invention is to provide a kind of bent folding, the lock that reduce volume, conveniently places and can rapid deployment use.

Lock provided by the present invention mainly is provided with: lock core rod, and the one end is established the core jack, and this lock core rod end extension in addition is provided with the pivot joint ear, and a side of lock core rod is provided with groove; At least one connecting rod, an end articulates with connector and lock core rod, and the connecting rod two ends respectively convex with the pivot joint ear, and a side of connecting rod is provided with the raised line corresponding with the groove of lock core rod, and the opposite side that connecting rod is established raised line then is provided with groove; Locking-bar, an end articulates with connector and connecting rod, and this locking-bar one end is provided with the pivot joint ear, and end then is provided with protruding coak in addition, can be provided with the raised line corresponding with the groove of connecting rod on locking-bar one side for the core jack that inserts lock core rod.

The present invention is described in detail with instantiation below in conjunction with accompanying drawing.

The specific embodiment

At first see also Fig. 2～shown in Figure 4, the present invention includes: lock core rod 2, the one end is established core jack 20, and this core jack 20 then is provided with keyhole 200 in the side in addition, the long-range extension of another of this lock core rod 2 is provided with the pivot joint ear 21 of two tools perforation 210, and the lateral surface of this lock core rod 2 is concaved with groove 22;

Connecting rod 3, articulate with connector 6 with lock core rod 2, these connecting rod 3 one ends are convexly equipped with the pivot joint ear 30 of tool perforation 300 laterally, for corresponding with the pivot joint ear 21 of lock core rod 2 one ends, be relative another long-range pivot joint ear 31 that then oppositely is convexly equipped with two tools perforation 310 of connecting rod 3, it is corresponding with the groove 22 of lock core rod 2 that the lateral surface of connecting rod 3 is provided with raised line 32, and connecting rod 3 another sides then are provided with groove 33;

Another connecting rod 4, articulate with connector 6 with connecting rod 3, these connecting rod 4 one ends extend the pivot joint ear 40 of establishing tool perforation 400 laterally, for corresponding with two pivot joint ears 31 of connecting rod 3, be relative another long-range pivot joint ear 41 that is provided with two tools perforation 410 that then oppositely extends of connecting rod 4, be provided with raised line 42 in addition in the side of connecting rod 4 corresponding with the groove 33 of connecting rod 3, and connecting rod 4 then is provided with groove 43 in the relative lateral surface of raised line 42;

Locking-bar 5, articulate with connector 6 with connecting rod 4, these locking-bar 5 one ends are convexly equipped with the pivot joint ear 50 of tool perforation 500 laterally, for articulating ear 41 corresponding pivot joints with two of connecting rod 4, another is long-range then to be provided with protruding coak 51, for inserting core jack 20 inner lock buckles, it is corresponding with the groove 43 of connecting rod 4 that this locking-bar 5 is provided with a raised line 52 at its lateral surface;

So, utilization connects aforementioned each assembly pivot group with connector 6, at first toward the outer side with a side of connecting rod 3 tool raised lines 32 and lock core rod 2 tool grooves 22, making one of connecting rod 3 articulate ear 30 1 ends again inserts between the two pivot joint ears 21 of lock core rod 2, and make the perforation 300,210 align the back with connector 6 pivot groups, the inferior connecting rod 4 of getting makes its groove 43 outwardly, end with one pivot joint ear 40 inserts between the two pivot joint ears 31 of connecting rod 3 again, respectively bore a hole 310 with connector 6 break-through again, 400 link two assemblies, at last, with locking-bar 5 outwardly with raised line 52, an end that makes one articulate ear 50 again inserts two of connecting rod 4 and articulates between the ear 41, equally with connector 6 break-through perforation 410,500 pivot groups, promptly constitute a lock, when desiring the snap close use, lock is launched to make locking-bar 5 pass wheel, protruding coak 51 1 ends are inserted in the core jack 20 of lock core rod 2, can realize snap close.

After triping, desires by lockset to amount to when placing, please cooperate and consult Fig. 3～shown in Figure 6, at first with lock core rod 2 and locking-bar 5 oppositely bending respectively, make the groove 22 of lock core rod 2 take in the raised line 32 of connecting rod 3, and in the groove 43 of the raised line 52 embedding connecting rods 4 of locking-bar 5, again connecting

rod

3,4 is folded relatively, so that embedding groove 33 interior can the finishing of connecting rods 3, the raised line 42 of connecting rod 4 folds, so can reduce volume (as shown in Figure 6), save the space that places.
