At present, the existing central control door lock comprises a shell, a motor, a gear set and a screw rod which are arranged in the shell, wherein one end of the motor is arranged in the shell, the other end of the motor extends to a pull rod outside the shell, an output shaft of the motor rotates to drive the screw rod to rotate through the gear set, the screw rod rotates to drive the pull rod to linearly move, the central control door lock is generally fixed through a mounting bracket, the mounting bracket is U-shaped, through holes are symmetrically formed in opposite side walls of the mounting bracket, and a pair of protruding blocks for sleeving the through holes in the mounting bracket are arranged on the shell.

However, when the existing central control door lock is installed, the lock cylinder is generally and directly fixedly connected through screws, so that the subsequent disassembly and maintenance are inconvenient.

Therefore, it is necessary to invent a central control door lock to solve the above problems.

Disclosure of Invention

The present utility model is directed to a central control door lock, which solves the above-mentioned problems.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a central control lock, includes lock core and casing, the slot has been seted up to one side of casing, and the inside activity of slot is provided with the lock core, the draw-in groove has all been seted up to the top and the bottom of lock core, the spout has been seted up to the top and the bottom inner wall of slot, and the inside activity of spout is provided with the fixture block with draw-in groove looks adaptation, the screw thread groove has been seted up to the one end that the lock core was kept away from to the fixture block, the tank bottom of spout is provided with the lead screw with screw thread groove looks adaptation through the bearing activity penetration, the one end that the fixture block was kept away from to the lead screw is fixed to be provided with the commentaries on classics piece.

Preferably, the inner wall of the slot is fixedly provided with a movable sealing layer, and the movable sealing layer is in fit connection with the lock cylinder.

Preferably, limit grooves are formed in the inner walls of the two sides of the sliding groove, and limit blocks matched with the limit grooves are fixedly arranged on the two sides of the clamping block.

The utility model has the technical effects and advantages that:

according to the lock cylinder clamping device, through the lock cylinder clamping arrangement, when the lock cylinder is dismounted, only the two rotating blocks are rotated to drive the corresponding screw rods to rotate, so that the clamping blocks are driven to slide in the sliding grooves, the clamping blocks move in the direction away from the clamping grooves until the clamping blocks are separated from the clamping grooves, and the lock cylinder is separated from the clamping grooves, so that the dismounting and mounting are simple and convenient.
