Description

electronic panel lock

technical field

The invention belongs to locks, in particular to an electronic panel lock.

Background technique

More and more panel locks now use electronic locks that combine electronic control with a high degree of intelligence and mechanical locks. In this type of electronic lock, a motor is generally used to drive the clutch device to realize the unlocking of the lock. However, there are some potential safety hazards in the existing electronic locks: one is that the motor and the clutch device are placed in the front panel, so that it is easy to be directly pried off the front panel to unlock the lock, or directly drill the hole in the front panel to remove the lock. The motor line is energized, and the clutch pin in the clutch device is combined with the clutch seat to realize unlocking, or after drilling the panel hole, use a small object to directly combine the clutch pin with the clutch seat to realize unlocking; The lock bolts on the lock body are interlocked. Once the front panel is damaged, you only need to turn the square lever to unlock it directly, which is very unsafe.

Contents of the invention

The purpose of the present invention is to provide an electronic panel lock with good safety performance.

The technical scheme adopted to realize the object of the present invention is: an electronic panel lock, including a lock body with a lock bolt, front and rear panels arranged on both sides of the lock body, front and rear handles respectively movable on the front and rear panels, and connecting the front and rear handles through the lock body. The first square bar; the rear panel is provided with a clutch device, a second square bar corresponding to the clutch device and linked with the lock bolt, the front handle and the first square bar are connected by the clutch device The connection between the rear handle and the second square rod realizes separation and engagement with the rear handle and the second square rod; or a clutch device is provided in the front panel, which is arranged correspondingly to the clutch device and is connected to the lock bolt The linked second square bar, the rear handle and the first square bar are connected with the front handle and the second square bar through the clutch device to realize separation and engagement with the front handle and the second square bar.

The clutch device includes a clutch seat arranged on the rear handle, a clutch core connected to the first square rod and rotatably matched with the clutch seat, and a clutch core arranged on the clutch seat radially connected to the clutch core. A matching elastic clutch pin and a driving device for driving the clutch pin to move, the clutch seat is connected to the second square bar through a connecting rod.

A spring is provided between the first square rod and the clutch core.

Beneficial effect:

In the present invention, the front handle is linked with the lock bolt and the rear handle through the clutch device. After locking, the front handle cannot be linked with the lock bolt, but can only idle, so it can prevent the prior art from directly rotating the first handle after the front panel is damaged. The defect of square lever unlocking. Because the present invention is arranged in the rear panel by the clutch device, it can prevent the situation that the clutch device is unlocked from being directly destroyed after the front panel is pried off. And because there is a spring between the first square rod and the clutch core, after the front panel is pried off, the rear panel loses the connection with the front panel, and the clutch device will be connected with the first square rod together with the rear panel under the action of the spring. disengage, so that the first square bar is separated from the second side bar and cannot be unlocked. Compared with the prior art, the invention has better safety performance.

The present invention will be further described below in conjunction with the accompanying drawings.

detailed description

Figures 1 to 5 show a fingerprint electronic panel lock using the present invention, including a lock body 20 arranged on the door leaf A, the lock body 20 is provided with a lock bolt 21, and on the door leaf A on both sides of the lock body 20 A front panel 18 and a rear panel 19 are provided, and the front panel 18 and the rear panel 19 are connected as a whole by bolts 24. The front panel 18 and the rear panel 19 are respectively movable with a front handle 1 and a rear handle 1′. The first square bar 16 passing through the lock body 20 is connected with the rear handle 1'; in the rear panel 19, a clutch device, a second lever arranged above the clutch device and linked with the lock bolt 21 is provided. Square rod 16'; the clutch device is shown in Figure 9, including a disc-shaped clutch seat 9 fixedly connected to the rear handle 1', a clutch core 901 that rotates with the clutch seat 9, and a clutch core 901 that is arranged on the clutch seat. On 9, the clutch pin 10 of the back-moving spring 15 arranged radially to cooperate with the clutch core 901, the driving device for driving the movement of the clutch pin 10, the clutch core 901 is flexibly connected with the clutch seat 9 through the central screw 12; the driving device includes The motor 11 and the arc-shaped top plate 1101 driven by the motor 11, the arc-shaped top plate 1101 corresponds to the clutch seat 9 and cooperates with the clutch pin 10 on the clutch seat 9, and the clutch core 901 is provided with a pin hole 902 corresponding to the clutch pin 10 And the square hole 903 that cooperates with the first square rod, the front handle 1 is fixedly connected with one end of the first square rod 16, and the other end of the first square rod 16 is inserted in the square hole 903 on the clutch core 901, and the square hole 903 is provided with There is a spring 23 against the end of the first square bar 16, the front handle 1 and the first square bar 16 are separated and joined with the rear handle 1' through the separation and engagement of the clutch seat 9 and the clutch core 901 in the clutch device, and The separation and engagement of the clutch seat 9 and the clutch core 901 is realized by driving the clutch pin 10 through the arc-shaped top plate 1101 of the driving device; The transmission dial 7 is connected, and at the same time, the front handle 1 and the first square bar 16 are separated and joined with the second square bar 16' through the clutch device; the front panel 18 is provided with a touch screen structural assembly 2 and a fingerprint structural assembly 3 , camera 14, the front handle 1 is fixed on the front panel 18 by the front handle 4 and the reset torsion spring 13, and the first square bar 16 is inserted into the square hole 401 of the front handle 4 to be connected with the front handle 1; Access control circuit board 5, battery box 6, battery box cover 17, safety button 22 are arranged.
