Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories, in particular to a buffer adjustment structure of a buffer door stopper. Background Art

[0002] With the progress of society, door suction is more and more widely used in people's lives. Due to certain needs in daily life, doors are required to be kept in an open state at all times. Door suction is widely used in various fields such as home, office, and production as a tool for fixing door panels. The door suction includes a door suction base and a door suction pile, which is mainly used to fix the door suction pile arranged on the door leaf to the door suction base arranged on the ground after the door leaf is opened, so as to achieve locking and positioning of the door leaf after opening, and to prevent the wind from blowing or touching the door leaf and causing the door leaf to close.

[0003] For example, a latch-type locking door stopper with a Chinese document announcement number of CN218844024U includes a door stopper head 1 and a door stopper seat 2. The door stopper seat 2 includes a seat body 201 and a lock tongue 202 and an elastic telescopic member 203 arranged on the seat body 201. The lock tongue 202 is rotated on the seat body 201 through a first hinge point a, and one end of the elastic telescopic member 203 is rotated on the seat body 201 through a second hinge point b. The other end of the elastic telescopic member 203 is rotated on the seat body 201 through a deflection point b. The central connection point c is rotatably connected to the lock tongue 202, and a latch member 3 is provided on the base body 201, and the upper end of the latch member 3 cooperates with the lock tongue 202; when in use, the door suction head 1 drives the lock tongue 202 relative to make it swing around the first hinge point a as the center, and the eccentric connection point c deflects after passing the collinear position of the first hinge point a and the second hinge point b, and the elastic telescopic member 203 drives the lock tongue 202 to continue to swing in the deflection direction, thereby achieving locking or unlocking of the door suction head 1 and the door suction base 2;

[0004] Another example is a cam-type deflection locking door stopper with a Chinese document publication number of CN218623765U, which includes a door stopper head 1 and a door stopper seat 2. The door stopper seat 2 includes a seat body 201, a lock tongue 202 and an elastic telescopic member 203 arranged on the seat body 201, the lock tongue 202 is rotated on the seat body 201 via a first hinge point a, one end of the elastic telescopic member 203 is rotated on the seat body 201 via a second hinge point b, and the other end of the elastic telescopic member 203 is rotated on the seat body 201 via a second hinge point b. The eccentric connection point c is rotatably connected to the lock tongue 202, and a latch member 3 is provided on the base body 201, and the upper end of the latch member 3 cooperates with the lock tongue 202; when in use, the door suction head 1 drives the lock tongue 202 relative to the first hinge point a so that it swings around the first hinge point a. The eccentric connection point c deflects after passing the collinear position of the first hinge point a and the second hinge point b. The elastic telescopic member 203 drives the lock tongue 202 to continue to swing in the deflection direction, thereby locking or unlocking the door suction head 1 and the door suction base 2;

[0005] In the above two structures, buffering is achieved by the elastic telescopic member 203, but the buffering function cannot be adjusted, so further improvement is needed. Utility Model Content
