Description
Technical Field
[0001] The utility model relates to the technical field of electronic locks, in particular to an electronic lock which is convenient for the left - right reversal of the handle. Background Art
[0002] In an electronic lock, a clutch assembly is usually arranged between the handle and the lock body. The clutch assembly is in a normally open state to disconnect the transmission connection between the handle and the lock body. When the fingerprint recognition or password input is correct, the electric drive device in the electronic lock will drive the clutch assembly to close, so that the handle and the lock body are in transmission connection. Thus, people can rotate the handle to drive the lock tongue of the lock body to retract into the lock body to unlock. In life, since some doors open to the left and some doors open to the right, when the electronic lock is installed on different doors, it is necessary to rotate the handle left - right and reverse it according to the actual situation to be used normally. For this reason, in some existing electronic locks, the clutch assembly includes a connecting seat for drivingly connecting the lock body, a clutch member, and a connecting head for connecting the handle. The connecting seat is rotatably installed inside one end of the clutch member. A clutch rod is slidably installed on the clutch member. The other end of the clutch member is rotatably installed on the connecting head, and the clutch member is fixed to the connecting head by more than two bolts. In the off - state, the clutch rod disengages from the connecting seat. At this time, the clutch member and the connecting seat can rotate relative to each other. When closing is required, the clutch rod can be inserted into the connecting seat under the push of the electric drive device so that the clutch member and the connecting seat can rotate together. When the handle needs to be reversed, first remove the bolts so that the connecting head can rotate relative to the clutch member. Thus, the handle can be rotated left - right to complete the reversal. During the reversal process, the relatively large - sized clutch member will not be driven to rotate, so that while the handle can be reversed left - right, the space for installing the clutch assembly of the electronic lock is reduced. However, for such an existing electronic lock, when the handle is reversed left - right, more than two bolts need to be disassembled and assembled, and the reversal of the handle is not convenient and simple enough.

[0035] According to some embodiments of the present utility model, a return torsion spring 530 is arranged between the clutch member 210 and the front panel housing 100. Thus, after the handle 300 drives the lock body to unlock through the closed clutch assembly, the clutch member 210 can be rotated and reset by the return torsion spring 530.
[0036] According to some embodiments of the present utility model, the return torsion spring 530 is sleeved on a side of the clutch member 210 close to the second mounting hole 130. The return torsion spring 530 is sleeved on the connecting head 220. The clutch cover plate 250 is fixedly installed on the clutch member 210 through a locking bolt 260. The end of the locking bolt 260 penetrates to a side of the clutch member 210 close to the second mounting hole 130. The return torsion spring 530 drives the clutch member 210 to reset by cooperating with the end of the locking bolt 260. Through the above arrangement, the clutch cover plate 250 can limit the connecting seat 230 and the clutch rod 240 on the clutch member 210 to prevent the connecting seat 230 and the clutch rod 240 from detaching from the clutch member 210. Among them, when the installation between the clutch cover plate 250 and the connecting seat 230 is completed, the locking bolt 260 can also cooperate with the return torsion spring 530 to drive the clutch member 210 to rotate and reset.
[0037] According to some embodiments of the present utility model, the clutch rod 240 is provided with an abutting portion 241. The second reset structure includes a second return spring 520.
