Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a door stopper structure. Background Art

[0002] When doors and windows are opened or closed, it is necessary to prevent them from generating excessive impact force to avoid damage and noise caused by violent collisions. After the doors and windows are opened, they also need to be kept in a stable state to prevent abnormal movements caused by wind or external force. In order to solve this problem, most of the methods used are to use door suction for buffering and adsorption. Door suction, commonly known as door bump, is a door leaf positioning device. Traditional door suction includes a door suction seat and a door suction pile. The door suction pile is fixed on the door leaf, and the door suction seat is fixed on the ground. When the door leaf is opened, the door suction pile is limited when it contacts the door suction seat, thereby limiting the door leaf and preventing the door leaf from rotating or closing freely.

[0003] When the existing door stopper seat is matched with the door stopper column, in order to prevent the door stopper seat and the door stopper column from being damaged when they collide, the door stopper column is provided with a buffer structure. The existing buffer mechanism usually adopts the card slot of the lock tongue to be matched with the door stopper column, and the lock tongue is set to be able to swing up and down, so that the lock tongue can be better connected to the door stopper column. However, the problem is that because the lock tongue is set to be able to swing up and down inside the door stopper seat, the internal space of the door stopper seat becomes larger, the height becomes higher, and the overall occupied space volume becomes larger, which is unsightly and hinders the passage of users. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of this, the embodiments of the present specification provide a door stopper structure with a simple structure and a small occupied space volume.

[0008] Compared with the prior art, the advantages of the utility model are: the lock tongue is driven relatively by the door suction column to swing around the first hinge point as the center, the eccentric connection point deflects after passing the colinear position of the first hinge point and the second hinge point, and the elastic telescopic member drives the lock tongue to continue to swing in the deflection direction, thereby realizing the limited engagement or unlocking of the door suction column and the door suction seat, the internal structure is simple and the stability is strong, and the upper cover swings up and down through the joint action of the first hinge point and the eccentric connection point, and because the other end of the elastic telescopic member is eccentrically connected to the lock tongue via the eccentric connection point, the elastic telescopic member is connected to the upper cover via the eccentric connection point, the upper cover slides back and forth relative to the base during the swinging process, and the upper cover swings with the swing of the lock tongue. The swingable setting of the upper cover optimizes the internal space of the base, and there is no need to consider the insufficient height of the internal space formed by the upper cover and the base due to the rotation of the lock tongue, so that the overall height of the door suction seat becomes lower and the overall occupied space volume becomes smaller.

[0009] In some embodiments, the left and right inner wall surfaces of the upper cover are each provided with a first limit groove, and the two first limit grooves are arranged opposite to each other. The elastic telescopic member is connected to the upper cover through the first rotating shaft of the second hinge point, and the two ends of the first rotating shaft are accommodated in the first limit groove. Through the improvement, the first rotating shaft is arranged in the first limit groove. When the lock tongue rotates, the lock tongue swings up and down with the upper cover, and the two ends of the first rotating shaft move in the first limit groove.

[0012] In some embodiments, the upper cover and the elastic telescopic part are hinged through a second hinge point, and the upper cover rotates around the second hinge point. Through the improvement, the upper cover and the elastic telescopic part are connected through the second hinge point, so that when the elastic telescopic part controls the lock tongue to swing up and down, it drives the upper cover to swing up and down around the second hinge point.

[0013] In some embodiments, a conducting groove connected to the outside is provided below the rear end of the second limiting groove, and a receiving groove for accommodating the rotating shaft of the second hinge point is provided on the inner wall of the upper cover. The receiving groove is connected to the outside, and cooperates with the second rotating shaft through the conducting groove, and the end of the second rotating shaft is placed in the second limiting groove through the conducting groove. The receiving groove cooperates with the rotating shaft of the second hinge point, and the end of the rotating shaft of the second hinge point is accommodated in the receiving groove, thereby realizing the installation of the upper cover on the base. Through the improvement, in the process of installing the upper cover on the base, first, the end of the second rotating shaft is placed in the second limiting groove through the conducting groove, and then the end of the second rotating shaft is slid in the second limiting groove, so that the end of the rotating shaft of the second hinge point is accommodated in the receiving groove, thereby realizing the installation of the upper cover on the base, and the installation is convenient and quick.

[0014] In some embodiments, the elastic telescopic part includes a telescopic rod and a spring. One end of the telescopic rod is connected to the lock tongue through a connecting head. The outer wall of the telescopic rod has a stop portion protruding outward. The connecting head includes a first limiting plane. The spring is sleeved on the outer wall of the telescopic rod, and the two sides of the spring are respectively against the stop portion and the first limiting plane. Through the improvement, the elastic telescopic part has an elastic force in the direction of the lock tongue through the setting of the spring.

[0015] In some embodiments, the connecting head includes a second limiting plane which is vertically arranged at the inner end of the first limiting plane and protrudes backward. The second limiting plane is inserted into the spring, and the outer wall surface of the second limiting plane is abutted against the inner wall surface of the spring. Through the improvement, the second limiting plane is inserted into the spring, and the outer wall surface of the second limiting plane is abutted against the inner wall surface of the spring, thereby preventing the spring from shaking radially during movement and maintaining the stability of the spring when working.

[0016] In some embodiments, the connecting head includes a third limiting plane which is vertically arranged at the outer end of the first limiting plane and protrudes backward. The third limiting plane is arranged on the outside of the spring, and the inner wall surface of the third limiting plane is abutted against the outer wall surface of the spring.

[0017] In some embodiments, the telescopic rod is a hydraulic telescopic rod with resistance. Through the above improvement, the elastic telescopic part can be more stable during movement.

[0018] (III) Beneficial effects

[0019] The utility model provides a door suction structure, which can effectively reduce the large impact force generated by the door on the door suction column and the door suction seat when the door is sucked, and plays a role in protecting the door frame and the floor. At the same time, it can effectively reduce the pulling force between the door suction column and the door suction seat when the door frame is opened, making it more convenient and more labor-saving for users to open the door. The elastic telescopic parts and lock tongues arranged inside can ensure that the door suction seat and the door suction column cooperate, making the suction and opening of the door panel more convenient. The overall structure is simple and the manufacturing cost is lower. The use of hydraulic telescopic rods can greatly enhance the shock absorption and buffering effect, and the internal structure is more reasonably arranged. The upper cover can be swingably arranged, and the upper cover is slidably arranged relative to the base, so as to optimize the internal space of the base. There is no need to consider the insufficient height of the internal space formed by the upper cover and the base due to the rotation of the lock tongue, so that the overall height of the door suction seat becomes lower, and the overall occupied space volume becomes smaller, which prevents the seat body from protruding too much and affecting the user's opening of the door, thereby ensuring the safety of use.
