Description

Dark bolt type lock

The utility model belongs to the technical field of the lock that spring hitch and locking bolt separate.

Our usefulness is locked in lock on the nose now, locking bolt is exposed to the outside, cut with sawing or with big iron shears and all to be easy to locking bolt is broken, and the snap of lock core is all to the lock body external compression, and from the material of outer enclosure snap, general is softer aluminium or lead, therefore also is easy to encapsulating material is taken off from lock body, thereby opens lock.

It is that hidden snap is the strong lock of tamper-resistant function that compresses in lock body that the purpose of this utility model provides a kind of locking bolt.

This dark bolt type lock comprises lock body, is contained in the lock core on the lock body, is contained in the spring in the hole of lock body, is pressed in the dead bolt that contacts with lock core on the spring, the locking bolt that buckles by lockhole and dead bolt, but be connected as a single entity and the locking closure of three limit fastenings on lock body with locking bolt.

Because locking bolt is built-in, can't see from the outside or touch it, therefore the anti-performance of cutting of anti-sled shearing resistance is stronger, snap on the lock core compresses in lock body, therefore the soft material that encapsulates snap does not reach from the outside of lock body yet, thereby can not open, thereby make that the whole anti-theft feature of this lock is very strong.

Accompanying drawing shows embodiment of the present utility model, wherein:

Figure 1 shows that the elevation of dark bolt type lock;

Figure 2 shows that along the sectional view of A-A line shown in Figure 1;

Figure 3 shows that the rear elevation of dark bolt type lock;

Figure 4 shows that the split figure of dark bolt type lock;

Figure 5 shows that assembling drawing when dark bolt type lock uses.
