Door stopper with locking function

Abstract

The door stopper with the locking function comprises a door stopper base and a lock body, the lock body comprises a lock body seat, the bottom of the lock body seat is connected with a locking column, a lock groove is formed in the door stopper base, spring bolt cavities are formed in the door stopper base respectively, first through holes are formed in the left side wall face and the right side wall face of the lock groove, spring bolts are movably arranged in the two spring bolt cavities, and the first through holes are formed in the left side wall face and the right side wall face of the lock groove respectively. Two spring bolt cavities are formed in the door stopper base, a locking cavity is formed in one side of the two spring bolt cavities, an unlocking clamping plate is arranged in the locking cavity, the front end of the unlocking clamping plate is provided with a stopping piece capable of stopping the spring bolts from retreating, and an unlocking piece is arranged on the lock base upper cover. A lock groove capable of allowing the locking column to enter is formed between the two lock tongue cavities, the lock tongues capable of closing the opening of the lock groove are installed in the two lock tongue cavities, the unlocking clamping plate can enable the stopping piece to stretch into the two lock tongue cavities to stop the door stopper of the lock tongues from retracting, and the door stopper is mute, simple in structure, light, easy to assemble and capable of effectively guaranteeing that the door stopper cannot be unlocked mistakenly.

Description

Technical field [0001] The present invention relates to the field of door suction, in particular to a door suction having a locking function. Background [0002] Door suction is also called door touch or ground suction, its main function is to fix the door leaf after the door leaf is opened, to prevent the door leaf from being blown by the wind and other situations by mistake, but also to prevent the door leaf from colliding with the wall when it is opened. [0003] The existing commercially available door suction is divided into several categories, one is to set metal parts on the bottom surface and the bottom end of the door leaf, set up magnets on the metal parts, use magnetic force to adsorb each other to achieve door leaf fixation, this kind of door suction, it is easy to separate from each other due to excessive external forces, and can not effectively prevent the door leaf from being blown by the wind and other situations by mistake, the other type is mechanical door sucti...

AI Technical Summary

Problems solved by technology

[0003] The existing commercially available door stoppers are divided into several categories. One type is to set metal parts on the bottom surface and the bottom of the back of the door leaf. Magnets are set on the metal parts, and the door leaf is fixed by magnetic force. If they are too large and separate from each other, it cannot effectively prevent the door leaf from being accidentally closed by the wind. The other type is a mechanical door stopper, such as a ground suction for a windproof door in Chinese patent CN210343025U. The door stopper of this type of structure is made of metal. The fixed base and the rod body are respectively installed on the bottom surface and the back of the door leaf. After the rod body enters the lock groove of the fixed base, squeeze the specific parts in the lock groove to rotate the rotating mechanism in the fixed base to lock the rod body, and squeeze the specific parts again to fix the rod body. The rotating mechanism in the base rotates again to release the rod

The internal structure of this type of mechanical door stopper is very complicated, and the probability of failure is very high, and this kind of mechanical door stopper realizes the lock switch function by squeezing specific parts, but in actual use, wind force often occurs. Or manpower mistakenly pushes the door leaf to move backward, and squeezes the switch to cause mistaken unlocking

Mechanical door stoppers also have non-rotation locks, but they also have a large number of small parts inside, with a high failure rate and cumbersome production and assembly.

[0004] In addition, the above two kinds of door stoppers, due to the complex internal structure, can only be realized by using metal parts when the door stoppers are collided for a long time, which will undoubtedly increase the manufacturing cost. Once damaged, it is difficult for users to repair. The cost of use is also higher

And in daily use, metal door stoppers cannot avoid the sound of collision, which is a source of noise that affects the work and rest of neighbors and family members
