Detailed Description

Example one

Referring to fig. 1-5, the present invention provides a technical solution:

a U-shaped padlock with a double-sided unlocking function is characterized in that two groups of symmetrical lock holes are formed in the surface of a lock body 2, a U-shaped ring 1 is inserted into the lock holes in the surface of the lock body 2, bolt holes are formed in the inner walls of the lock holes of the lock body 2, limiting pins 11 are inserted into the bolt holes, and after the U-shaped ring 1 is inserted into the lock body 2, the limiting pins 11 are inserted into the limiting holes in the surface of the U-shaped ring 1, so that the U-shaped ring 1 and the lock body 2 can be locked;

the central point that lies in two sets of lockholes on the lock body 2 simultaneously puts and is connected with lock core 3, two ends of lock core 3 all run through lock body 2 and with the surface looks parallel and level of

lock body

2, 3 interpolations of lock core are equipped with the key 4 of looks adaptation, through key 4 control lock core 3 internal rotation in lock body 2, thereby control two sets of spacer pins 11 of establishing in the lock body 2 and relieve locking to U type ring 1, make U type ring 1 and lock body 2 can open, and because lock core 3 is both ends equal insertible key 4 on 2 surfaces of lock body, make lock body 2 can be followed two faces and opened, further make U type ring 1 no matter from which face and lock body 2 lock the back, all can open fast.

A plurality of groups of limiting springs 5 are arranged inside the lock body 2, a plurality of groups of elastic columns 6 matched with the limiting springs 5 are arranged inside the lock body 2 and the lock cylinder 3, and convex teeth matched with the limiting springs 5 and the elastic columns 6 are arranged on the surface of the key 4, so that after the key 4 is inserted into the lock cylinder 3, the limiting springs 5 and the elastic columns 6 can be triggered, the lock cylinder 3 can be further controlled to rotate in the lock body 2, and the structure of the part is a conventional lock cylinder arrangement and is not elaborated;

the lock body 2 and the spring columns 6 arranged in the lock cylinder 3 are distributed in a central symmetry manner, and the convex teeth on the surface of the key 4 are also distributed in a central symmetry manner, so that the key 4 can completely trigger the limiting spring 5 and the spring columns 6 no matter which surface of the lock body 2 is inserted into the lock cylinder 3, and the U-shaped ring 1 and the lock body 2 are opened;

a control groove is formed in the lock body 2 at the central position, the surfaces of two sides of the lock core 3 in the control groove are connected with convex blocks 7, the convex blocks 7 are hinged with connecting rods 9 through first hinged shafts 8, bolt holes in the lock body 2 are formed in two sides of the control groove, two groups of limiting pins 11 are inserted into the bolt holes and then retract into the control groove, the other ends of the two groups of connecting rods 9 are hinged into sliding grooves in the surfaces of the two groups of limiting pins 11 through second hinged shafts 10, when a key 4 is inserted into the lock core 3 to control the lock core 3 to rotate in the lock body 2, the length of the connecting rods 9 is fixed, the limiting pins 11 can be pulled to slide in the bolt holes, and the two groups of limiting pins 11 are further retracted into the control groove, so that the U-shaped ring 1 can freely slide in lock holes in the surface of the lock body 2;

the surface sliding groove of the limiting pin 11 is internally connected with a reset spring 12, the other end of the reset spring 12 is connected to the second hinge shaft 10, when the lock cylinder 3 is locked in the lock body 2 and the U-shaped ring 1 needs to be inserted into the lock body 2, the U-shaped ring 1 can push the limiting pin 11 inwards in the bolt hole in the inserting process, so that the limiting pin 11 slides on the surface of the connecting rod 9 and further retracts into the control groove until the U-shaped ring 1 is inserted into a proper position, and the limiting pin 11 can reset under the elastic force action of the reset spring 12 due to the fact that the connecting rod 9 and the second hinge shaft 10 are fixed, so that the limiting pin 11 is inserted into the limiting groove on the surface of the U-shaped ring 1 to achieve locking;

and the spacing groove on U type ring 1 surface sets up to trapezoidal form for can guarantee throughout to jack up spacer pin 11 when U type ring 1 inserts towards lock body 2, singly can't pull out U type ring 1.
