Description

U-shape lock

Technical field

The utility model relates to a kind of U-shape lock.

Background technology

Existing U-shape lock no matter be the fixing type that rotarily opens of lock bridge one end or the lock bridge two ends are the tapered end type; All be simply to open lock core can open on its function with key; The U-shape lock that this function singleness does not have the insurance unlatching can not satisfy the demands of consumers, and the U-shape lock of other band insurance function then structure is comparatively complicated.

Summary of the invention

The utility model technical problem to be solved provide a kind of simple in structure, have a U-shape lock that insures open function.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of U-shape lock comprises lock body and lock bridge; Said lock body is provided with locking bolt, lock core, locking bolt starting plate, locking bolt is released the button and returning spring; Said locking bolt is connected with returning spring and can be installed in slidingly on the lock body, and locking bolt is provided with the locking bolt oblique angle near the top of lock core one end, the lock core flat piece that said lock core is provided with; Said locking bolt starting plate can slide up and down and be installed on the lock body; Locking bolt is released the button to match with the locking bolt starting plate and merge to be driven the locking bolt starting plate and move downward, and locking bolt starting plate lower end is provided with the oblique angle, and locking bolt one end matches with lock bridge; The locking bolt other end matches with the lock core flat piece that lock core is provided with, and the oblique angle that said locking bolt starting plate lower end is provided with matches with the locking bolt oblique angle that the locking bolt top is provided with.

The beneficial effect of the utility model is: because in the technique scheme, lock core is provided with lock core flat piece, when lock core forwards lock core flat piece with the corresponding locking bolt in the both sides of broad to; Locking bolt can't move to the centre and break away from lock bridge; Be in locking state this moment, insert key rotation lock core 90 degree after, when making lock core flat piece with the corresponding locking bolt in narrower both sides; Pressing locking bolt releases the button and drives the locking bolt starting plate and move downward; The oblique angle that locking bolt starting plate lower end is provided with drives locking bolt through matching with locking bolt oblique angle that locking bolt is provided with and moves to the centre, thereby make locking bolt break away from lock bridge U-shape lock is opened, therefore this U-shape lock simple in structure, have an insurance open function.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.

The specific embodiment

Like Fig. 1, Fig. 2, Fig. 4, Fig. 5, Fig. 6, Fig. 7, shown in Figure 8; A kind of embodiment of the U-shape lock that the utility model provides; Comprise lock body 1 and lock bridge 2; Said lock body 1 is provided with two locking bolts 3, lock core 4, locking bolt starting plate 5, locking bolt 6 and two returning springs 7 of releasing the button; Said two locking bolts 3 are distributed in lock body 1 both sides, and every locking bolt 3 all is connected with corresponding returning spring 6 and can be installed in slidingly on the lock body 1, and every locking bolt 3 is provided with locking bolt oblique angle 3-1 near the top of lock core one end; The lock core flat piece 4-1 that said lock core 4 is provided with; Said locking bolt starting plate 5 can slide up and down and be installed on the lock body 1, and locking bolt is released the button and 6 matched with locking bolt starting plate 5 and merge to drive locking bolt starting plate 5 and move downward, and lower end, locking bolt starting plate 5 left and right sides is equipped with oblique angle 5-1; Article two, an end of locking bolt 3 matches with lock bridge 2; Article two, the other end of locking bolt 3 matches with the lock core flat piece 4-1 that lock core 4 is provided with, corresponding the matching of locking bolt oblique angle 3-1 that two oblique angle 5-1 that lower end, said locking bolt starting plate 5 left and right sides is provided with are provided with two locking bolt 3 tops respectively, and concrete open method is: use key to open lock core 4; The lock core flat piece 4-1 that lock core 4 is provided with forwards the end of narrow both sides facing to locking bolt 3 to; Press locking bolt again and release the button and 6 drive locking bolt starting plates 5 and move downward, move to the centre and make two locking bolts 3 break away to open U-shape lock, the characteristics that this double end open-type U-shape lock has is simple in structure, band insures open function with cooperating of lock bridge 2 thereby two oblique angle 5-1 that lower end, locking bolt starting plate 5 left and right sides is provided with drive two locking bolts 3 respectively through matching with locking bolt oblique angle 3-1 that two locking bolts 3 are provided with.

Like Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8; The another kind of embodiment that the utility model provides; Said lock body 1 one ends are the lock body hinged end; The other end of lock body 1 is a lock body tapered end end, and said lock bridge 2 one ends are the lock bridge hinged end, and the other end of lock bridge 2 is a lock bridge tapered end end; The lock body tapered end end of said lock body 1 is provided with locking bolt 3; The lock bridge hinged end of said lock bridge 2 is hinged on the lock body hinged end of lock body 1 rotationally, and the locking bolt 3 in the other end lock bridge tapered end end of lock bridge 2 and the lock body tapered end end of lock body 1 matches, 2 one of this lock bridges be hinged on the lock body 1 other end cooperates with locking bolt 3 U-shape lock that plays locking function have equally simple in structure, be with the characteristics of insuring open function.
