Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to an electric bolt. Background Art

[0002] A door latch is a simple tool used to lock a door from the inside. Its simple structure and reliable performance make it a basic lock. However, for doors with a biparting design, existing door latches typically consist of an L-shaped movable pin that fits into a pin hole. A hanging plate is attached to the L-shaped movable pin, and a hook is attached to the other door. After the pin is inserted into the lock hole, the hanging plate snaps onto the hook. While this simple structure suffers from large gaps and poor security, posing the risk of someone prying the L-shaped movable pin apart through the door gap. Therefore, a more secure and convenient door latch is needed to meet user needs.

[0003] Chinese patent CN110469218A discloses an anti-theft fastening door pin for double doors. By cooperating with a gear and a rack, a rocker rotates the gear to further drive the rack to move to achieve the door pin function, which can effectively reduce the risk of the gear rod being opened through the door gap, thereby improving safety.

[0004] However, if the above device is damaged during actual use, the door will lose its protective function, and the above device needs to be opened and closed manually, which is very inconvenient. Therefore, it is necessary to develop an electric bolt installed on the existing key door to provide dual protection and solve the problem of manual opening and closing of the bolt. Summary of the Invention

[0018] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] See Figure 1 The utility model provides an electric bolt, which is an electric auxiliary bolt lock for a double door. The bolt includes a first base 1, a second base 2 corresponding to the first base, and a remote control 11 for controlling the electric bolt. The first base 1 is provided with a bracket 8 and a screw motor 4. The housing of the screw motor 4 has a first end for mounting a screw and a second end opposite to the first end. The first end is rotatably connected to the bracket 8 by a first bolt 7. A slider 5 is engaged with the screw of the screw motor 4. The slider 5 is fixedly connected to one end of the connecting rod 6. The opposite end of the connecting rod 6 is connected to a lifting rod 9. The lifting rod 9 is integrally formed with the connecting rod 6. The lifting rod 9 has a fixed end rotatably connected to the bracket 8 by a second bolt 701, and a rotating end opposite to the fixed end. The second base is provided with a card slot 10 corresponding to the rotating end. The first base 1 is also provided with a controller 3, which drives the controller 3 to be electrically connected to the screw motor 4.

[0020] Specifically, the drive controller 3 is provided with a drive power supply, a signal receiver, and a drive module. The drive power supply is a 24V power supply. The drive power supply, the signal receiver, and the drive module are electrically connected.

[0021] Specifically, the remote controller 11 is provided with a signal transmitter and a control switch button.

[0022] When in use, the device is installed on a door with a key lock, and the remote control 11 is pressed to control the switch button. The signal receiver in the drive controller 3 receives the signal sent by the remote control 11, and the drive module in the drive controller 3 drives the screw motor 4. The screw motor 4 rotates up and down under the support of the slider and the action of gravity. At the same time, the screw of the screw motor 4 rotates forward. The forward rotation of the screw causes the slider 5 to move on the screw rod, and the slider 5 drives the connecting rod 6 to rotate. The connecting rod 6 drives the lifting rod 9 to lift from the slot 10. At this time, the device is in the open state.

[0023] Furthermore, when the remote control 11 control switch button is pressed again, the signal receiver in the drive controller 3 receives the signal sent by the remote control 11, and the drive module in the drive controller 3 drives the screw motor 4. The screw motor 4 rotates up and down under the support of the slider and the action of gravity. At the same time, the screw of the screw motor 4 reverses, and the screw reversal causes the slider 5 to move on the screw, and the slider 5 drives the connecting rod 6 to rotate, and the connecting rod 6 drives the lifting rod 9 to fall into the slot 10. At this time, the device is in a closed state.

[0024] In summary, this application provides double protection for users by installing this device on the existing key door. Even if the key lock is damaged, it can provide protection for users, improve the overall security of the key door, and the remote control can also be used to open and close the latch, which is very convenient.
