Embodiment Construction
[0047] Figure 1-8Shown is the first embodiment of the idling lock head of the present invention, consisting of idling core 2, lock body 3, unlocking clutch pin 5, flat bead 8, flat bead spring 7, idling pin 14, annular locking plate 18, lock core sleeve 11. Matching key 1, lock plate spring 19, side pin 10, etc., the idler core 2 is in front, and the lock core sleeve 11 is behind, which are placed in the inner hole of the lock body 3 together, and the lock core sleeve 11 is covered with idle rotation The core 2 and the lock core sleeve 11 can only be covered with a part of the idle core 2, or the entire idle core 2 can be placed in the inner hole of the lock core sleeve 11, and the idle core 2 is provided with an idle pin groove 13 in the axial direction. There are also several annular grooves 17 connected with the idler pin groove 13 on the idle core 2, and an annular locking plate 18 and a locking plate spring 19 are arranged in the annular groove 17, and each annular locki...

The invention discloses a ring groove-type idling lock head comprising a lock body, an idle core with a keyhole and a lock core sleeve, and is characterized in that after the lock core sleeve hitches the idle core, the lock core sleeve and the idle core are put into the inner hole of the lock body together; the lock core sleeve is an unlocking main body; the idle core is provided with a plurality of ring grooves; circular lock pieces and lock piece springs are arranged in the grooves; the circular lock pieces are provided with grooves; an idle keyway is also arranged on the idle core; idle pins are arranged in the grooves; convex edges are arranged on the idle pins; the convex edges are matched with the grooves on the circular lock pieces; each idle pin is provided with a surface A and a surface B; side pin holes are arranged on corresponding positions of the surfaces A and B of the idle core; side pins are arranged in the side pin holes; the surfaces D and C on the side pins are matched with the surfaces A and B on the idle pins; unlocking clutch pin holes are arranged on positions of the lock core sleeve which correspond to the side pin holes; locking holes are arranged at the positions of the lock body which correspond to the unlocking clutch pin holes; and the unlocking clutch pins are arranged in the unlocking clutch pin holes and the side pin holes. When in a locked state, the idle core and the lock core sleeve are separated, the idle core can be randomly rotated and a lock keeps being locked, and the anti-theft performance is very high.
Description
technical field [0001] The invention relates to a lock, in particular to a ring groove type idling lock head. Background technique [0002] The usual leaf lock locks the rotation of the lock cylinder through the leaves. Only one leaf and one spring are installed in each leaf slot in the lock cylinder. When locking, the leaves installed in the lock cylinder are under the action of the spring force. Entering the groove of the lock body makes the lock cylinder and the lock body unable to rotate relative to each other. When the matching key is inserted, the key makes the blade move away from the lock body groove and completely enter the lock cylinder, and the lock cylinder can rotate relative to the lock body. The problem with this kind of lock is: due to processing errors, the plates cannot block the lock body at the same time, and the perpetrator can easily use tools to remove the plates one by one, thereby opening the lock. It is also easy to use a master key, a lock gun, etc...
