【Embodiment】

The utility model is described in further detail below in conjunction with the accompanying drawings：

A kind of U-shape lock, it includes lock body 1, and one end of U-shape lock beam 2 is be hinged with lock body 1, and the other end of U-shape lock beam 2 is locked Lock core 3 on body 1 locks, and lock body 1 is provided with lock pin 4 and the back-moving spring 5 resetted with pendulum lock pin 4；Lock pin 4 is provided with and lock core 3 First neck 41 of clip, and the second neck 42 with the clip of U-shape lock beam 2；Lock core 3 includes lock core shell 31, is set in lock core shell 31 Having can be in the lock gall 32 of the internal rotation of lock core shell 31, and drives the torsion spring 33 of the reset of lock gall 32, the clip of 32 and first neck of lock gall 41, The afterbody of lock gall 32 is additionally provided with slot to make way 321；U-shape lock beam 2 is provided with the U-shaped slot of the locked beam 21 of clip lock pin 4.

The afterbody of lock gall 32 of the present utility model can coordinate clip with the first neck 41, that is to say, that the afterbody cocker of lock gall 32 Enter into the first neck 41, the size of the first neck 41 is more slightly larger than lock gall 32, facilitates the afterbody of lock gall 32 and can snap onto first In neck 41.

It is half-moon groove that slot to make way 321 of the present utility model, which is preferably also, the second neck of the present utility model and U-shaped slot of the locked beam It is half-moon groove.

Lock core shell 31 of the present utility model is provided with lock core shell stopper slot 311, and described lock body 1 is provided with to be limited with lock core shell The spacer pin 11 that position groove 311 coordinates.

Lock body 1 is rectangular body, and lock core 3 is to justify body, the axis of lock core 3 and the upper plane of lock body 1 or lower plane shape In angle of 45 degrees, 45 degree of unlockings during unlocking, it is convenient to unlock.

One end of U-shape lock beam 2 is be hinged by bearing pin 6 and lock body 1, and bearing pin 6 is combined by two first quarter moon axles 61, and two and half Month axle 61 is provided with the hole 63 that supply and marketing axle securing rod 62 passes through.

The outer surface of U-shape lock beam 2 is also enclosed with gum cover 20.

Reinforced steel beam and girder 10 is additionally provided between the internal cylinder 3 of lock body 1 and bearing pin 6.

In lock-out state, lock pin 4 is stuck in the U-shaped slot of the locked beam 21 of U-shape lock beam 2 the utility model, is played and is only locked Effect, while the clip of 32 and first neck of lock gall 41 of lock core 3, it can not skid off and unlock U-shape lock beam 2, the insertion lock of spacer pin 11 In core shell stopper slot 311, lock core 3 can not be deviate from.

When unlocking, lock core 3 is inserted the utility model by correct key, and dextrorotation turn 90 degrees the i.e. rotation of lock gall 32 90 Degree, the slot to make way 321 of the afterbody of lock gall 32 decontrol the clip to the first neck 41 of lock pin 4, lock pin 4 is resetting also with rotation Ejected in the presence of spring 5, stop bit when the first neck 41 of lock pin 4 bumps against the root of the slot to make way 321 of lock gall 32, now, lock Second neck 42 of pin 4 is to the radial position to U-shape lock beam 2, unblock U-shape lock beam 2.
