Description

TECHNICAL FIELD

[0001] The utility model relates to an intelligent anti-theft door lock, especially to a handle unlocking structure of an intelligent external anti-theft door lock body. BACKGROUND

[0002] The external anti-theft door lock is an old product that has entered the families of common people in the 1980s. It has won the reputation of long-lasting popularity in the market due to its simple structure, easy installation and low price. It is especially favored by city rental apartments. With the rapid development of the society and the continuous deepening of technological innovation, various intelligent door locks have also appeared on the stage, but rental apartments and small town residents are still reluctant to give up the external anti-theft door lock. Therefore, after technological innovation, this product has become a new darling of the intelligent lock market and has occupied a part of the market share of intelligent locks. However, the external door lock needs to pull the pull buckle to unlock and open the door in the room, but it is relocked after the hand is released. It is inconvenient to use. For example, the patent number 2022221647238, named "electronic drive unlocking structure of intelligent external anti-theft door lock", still retains the original pull buckle unlocking structure. The pull buckle is pulled to unlock in the room, and the door is relocked after the hand is released. It is more convenient to use the handle to unlock without relocking.

[0003] Based on the above technical defects, it is necessary to study a handle unlocking structure of an external anti-theft door lock body, which can achieve the requirements of automatic unlocking and key unlocking, and unlock in the room without relocking, which is convenient and fast. SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model is to solve the innovation of the handle unlocking structure of the external anti-theft door lock. After structural optimization, the handle unlocking is faster and will not bounce to relock the door.

[0005] Implement a handle unlocking structure of an intelligent external anti-theft door lock body. The anti-theft door lock body is composed of a faceplate and an external door lock. A handle is arranged at the rear end of the external door lock. When unlocking and opening the door in the room, the handle is pulled. The handle will be offset in the direction of the pulling force, so that the external door lock will pull the door open when unlocking, making it convenient and fast for users to open the door in the room.

[0006] The handle is used for unlocking. The unlocking structure is that the handle is arranged at the rear end of the external door lock. It is composed of a handle, a compression spring, a pulling shaft, a reset compression spring and a transmission piece. Its feature is that the handle is first riveted at the rear end of the lock shell with a compression spring sleeve screw, then the pulling shaft is inserted into the rear end of the lock shell hole, and then the reset compression spring is inserted into the transmission piece shaft hole and the pulling shaft fixed piece, and then the clamping ring is locked in the clamping groove of the shaft rod to form the handle unlocking structure.

[0007] The handle is provided with a screw hole and a pulling shaft hole at the bending part; the pulling shaft is provided with a reset compression spring clamping groove; and the transmission piece is provided with a shaft hole, an expansion slot and an antenna.

[0008] The transmission piece is arranged below the motor and the gear transmission piece, and the feeler is fitted in the curve of the unlocking piece.

[0009] The unlocking piece is provided with a switch button, which is arranged in the hole of the lock shell and is fixed with the unlocking piece, so that the user can unlock the door in the room.

[0010] Advantages

[0011] The handle unlocking structure of the intelligent external anti-theft door lock body mainly solves the problem that the handle is pulled to 20 degrees or so in the direction of the pulling force when unlocking the door in the room, and the external door lock is pulled open in the unlocking state, so that the door is unlocked quickly through one handle opening operation, and the user can open the door in the room conveniently and quickly.
