The top of the lock cylinder 4 is provided with a convex block 43, the convex block 43 is sleeved with a knob cap 2, the bottom of the knob cap 2 is provided with a clamping groove 22, the convex block 43 is inserted into the clamping groove 22, the knob cap 2 can drive the lock cylinder 4 to rotate, and the top of the knob cap 2 is provided with a handheld part 21 which is convenient to rotate.

The outer wall of the rotating sleeve 3 is symmetrically provided with limiting clamping grooves 32, an elastic clamping piece 6 is arranged in the shell 1, the elastic clamping piece 6 is provided with a supporting arm 61 extending out, the front end of the supporting arm 61 is provided with a clamping block 62, and the clamping block 62 can be clamped into the limiting clamping grooves 32 to prompt that locking is performed; the fixture block 62 is provided with a guide surface for facilitating the fixture block to be separated from the limiting fixture groove 32.

The guide surface is an arc surface or an inclined surface.

A protruded rotating block 44 is arranged on one outer side wall of the lock cylinder 4, a plurality of spaced supporting blocks 33 are arranged in the rotating sleeve 3, and the rotating block 44 can be movably pressed on the supporting blocks 33; the top of the supporting block 33 of one block is provided with a limiting step 341, and the limiting step 341 can block the movement of the rotating block 44 so as to limit the maximum rotation amount thereof.

The interval of the supporting blocks 33 is smaller than the width of the rotating block 44.

The lock core 4 is connected with a lock head 7, a lock plate connecting part 73 is arranged at the bottom of the lock head 7, and various different lock plates can be installed on the lock plate connecting part 73 for locking.

The bottom of the lock cylinder 4 is provided with a square connecting raised head 45, the top of the lock head 7 is provided with a square locking groove 71, and the connecting raised head 45 is inserted into the locking groove 71 so as to limit the mutual rotation between the lock cylinder 4 and the lock head 7; the lock cylinder 4 is provided with a threaded hole 72, and the lock cylinder 4 is provided with the lock head 7 by means of threaded connection.

The device has a battery and a circuit board in the housing 1, and an infrared control board 12 is connected with the circuit board, and the battery and the circuit board are matched with each other to work for controlling the electromagnetic device 5. The touch panel 11 of the device is provided with an unlocking lamp 112 and a locking lamp 113, which can indicate the current working state.

The device has two unlocking modes, one mode is a key unlocking mode, and the other mode is an electronic unlocking mode adopting a digital password.

When the key is adopted, the key is inserted into the lock cylinder, and the lock cylinder can be rotated after the lock block is extruded, so that unlocking is completed. The locking blocks of the device have different structures, so that a special key is needed for extruding all the locking blocks simultaneously, and people do not need to worry about unlocking.

In another electronic unlocking method, a correct password needs to be input on the touch panel. When the input is correct, the electromagnetic device 5 is energized, so that the locking bar 51 is retracted and disengaged from the stop groove 31, and the factor limiting the rotation of the sleeve 3 is eliminated. At this time, the knob cap 2 can be twisted by hand to rotate the key cylinder 4. At this time, the lock piece still snaps into the key cylinder 4 to restrict the mutual rotation of the two, but the two can rotate together, so that the unlocking can be completed.

The elastic clamping piece 6 of the device is matched with the rotating sleeve 3, so that a user can be reminded when the locking and the unlocking of the knob cap 2 are started after the locking is finished. In particular, the support arms 61 have a certain elasticity, so that the two support arms 61 can be separated from each other by a certain distance. The fixture block 62 is clamped in the limiting clamping groove 32, and when the knob cap 2 is screwed to unlock, the rotating sleeve 3 rotates, so that the fixture block 62 is separated from the limiting clamping groove 32. During the period from the time before the detachment to the time when the detachment is completed, the latch 62 acts on the limit latch groove 32, and there is a force for limiting the screwing of the knob cap 2. The user can feel the acting force, and after the user twists the knob cap 2, the limit of the acting force is broken, and obvious feedback effect can be felt. This feedback can alert the user. In addition, when the user twists the knob cap 2, the fixture block 62 is clamped into the limit clamp groove again, and a very obvious feedback effect can be sensed. Thus, the user can be reminded whether the lock is locked or unlocked.

The electronic unlocking mode of the device can replace the infrared control panel 12 with another control panel. Such as an electrical signal control board 120. The electrical signal control board 120 is provided with contacts 130. When a person presses his finger on the top, an electrical signal can be generated. Thereby enabling a determination of which digit was pressed by the user. With the arrangement, the digital area can be omitted from being directly displayed on the touch panel 11 of the device, so that the appearance is more attractive.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
