Detailed ways

Shown in Fig. 1, Fig. 3, it is the three-dimensional view of the present utility model, and Fig. 2 is its three-dimensional exploded view, and it comprises a lock end 1, a lock cylinder 2, a lock core 5, a dial block 4, an elastic element 6, More than one set of lock control groups 7 and a lock bolt 3, wherein:

The lock head 1 has a lock body chamber 10 for the accommodation of the lock cylinder 2, and a lock bolt hole 13 is provided on the side of the lock body chamber 10;

The lock cylinder 2 has a through hole 21 for the accommodating of the lock core 5, and the bottom of the through hole 21 is provided with a first positioning groove 211, and corresponding to the lock bolt hole 13 is provided with a lock bolt insertion chamber 22, which communicates with the through hole 21;

The lock core 5 is provided with a key hole 51 at one end and with an action block 52 at the other end;

The shifting block 4 is a semi-cylindrical block, which includes a first action surface 401 and an arc-shaped second action surface 402, and one end of the shift block 4 is provided with a protruding portion 41 , the outer surface of which is provided with a second positioning groove 411;

The first end pin 61 of the elastic element 6 is sleeved in the first positioning groove 211, and the second end pin 62 is sleeved in the second positioning groove 411;

The lock control group 7 is driven by a key 54 to control the opening and closing of the lock core 5 and the lock cylinder 2 (as shown in Figure 6). 71. An outer lock bead 72, a spring 73 and a plug sleeve 74 are formed, and installed in the lock bead holes 53 and 23 of the lock core 5 and the lock cylinder 2 in sequence (this part is an existing Components and technologies, so no more details);

One end of the lock bolt 3 is provided with a lock bolt head 31 , and the lock bolt head 31 is composed of a head end 311 and a card slot 312 .

By virtue of the composition of the above components, when the utility model is to be locked, first insert the lock bolt head 31 into the lock bolt hole 13 and go deep into the lock bolt insertion chamber 22 as shown in Figure 4 step (a), the lock bolt head 31 The head end 311 pushes against the first action surface 401 of the shifting block 4, so that the shifting block 4 is twisted and the elastic element 6 is compressed as shown in FIG. 4 step (b) and FIG. 5, and After the head end 311 is pushed forward to the bottom, the second action surface 402 of the shifting block 4, because it is a circular arc surface, is subjected to the restoring elastic force of the elastic element 6, so that the shifting block 4 is rotated back to its position , and snap into the slot 312 of the lock bolt head 31, and then turn it to the locked position with the key 8, to drive the action block 52 to link the shift block 4, and lock the lock bolt head 31 as shown in the steps in Figure 4 ( As shown in c), the locking operation can be completed.

As shown in Figures 6 and 7, when the key 54 is inserted into the key hole 51, the contact position between the inner lock bead 71 and the outer lock bead 72 of the lock control group 7 is located on the opening line P, and the lock core 5 can therefore rotate. The action block 52 and the shifting block 4 are in a free and non-blocking state, so the lock head 31 will not be blocked, and the user only needs to pull it out from the lock hole 13 to complete the unlocking operation.

Again its structure of the present utility model is in order to general use in the use of bicycle lock, more can be extended with a side connection room 101 (as shown in Figure 2, Figure 8) at the side of its lock body chamber 10 of described lock head 1, One end edge 81 of a cable body 8 can be plugged into the side connection chamber 101, and the other end edge 82 of the cable body 8 can be connected to the lock bolt head 31, so that it can be used universally. Locks for different purposes can effectively reduce inventory preparation.

To sum up, the lockset of the present invention can be used universally in many kinds of locksets with different purposes, and its components are simple, which can effectively reduce the inventory cost, and is particularly beneficial for progress.

The above description is only illustrative, rather than restrictive, of the present utility model. Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined in the claims. But all will fall within the limitable scope of the claims of the present utility model.
