Technical Field

[0001] The utility model relates to the technical field of door stops, and more specifically, to a door stopper for indoor doors. Background Art

[0002] Door suction, also known as door stopper, is a device that holds the door in place after it is opened to prevent the door from being closed by wind or touching it. Traditional door suction consists of a suction head and a suction base. The suction head is installed at the bottom of the door, and the suction base is installed on the wall or floor. The main principle of traditional door suction is to use the magnet of the suction base to attract the suction head on the door to fix the position of the door. However, the magnetic force of the magnet is relatively limited. When the door is subjected to a large force, it will directly collide with the suction base and rebound, and it is impossible to stably fix the door. Utility Model Content

[0008] As a preferred technical solution of the utility model, the two wire steels pass through the middle of the two gears respectively, and the thread directions of the surfaces of the two wire steels are opposite.

[0009] As a preferred technical solution of the utility model, the magnetic block is made of a magnet, and when the magnetic block moves to contact with the suction seat, the iron column is adsorbed downward.

[0010] As a preferred technical solution of the utility model, the iron column is made of iron, and when the iron column is adsorbed downward, it contacts the inner surface of the waist-shaped groove.

[0011] As a preferred technical solution of the utility model, a rubber pad is sleeved on the outer surface of the semicircular slider, and the semicircular slider contacts the surface of the chassis groove when moving left and right.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 6 As shown, the utility model provides a door stopper for indoor doors, including a chassis 1, a suction seat 2 is fixedly installed on the top of the chassis 1, a waist-shaped groove 3 is opened in the middle of the top of the suction seat 2, a rectangular groove 4 is opened below the waist-shaped groove 3, a "U"-shaped baffle 5 is fixedly installed in the middle of the top of the suction seat 2, gears 6 are rotatably installed at both ends of the middle part of the right side of the "U"-shaped baffle 5, wire steels 7 are meshed in the middle of the two gears 6, and magnetic blocks 8 are fixedly installed on the bottom of the two wire steels 7.

[0024] By setting two gears 6 to rotate, the wire steel 7 drives the magnetic block 8 to move upward. When the magnetic block 8 moves to contact with the suction seat 2, the magnetic force is used to make the iron column 16 adsorbed downward and contact with the magnetic block 8. The iron column 16 can be fixed by the waist-shaped groove 3, thereby achieving stable fixation of the door.

[0025] A chassis groove 9 is provided on the right side of the chassis 1 , a spring 10 is fixedly installed inside the chassis groove 9 , and a semicircular slider 11 is fixedly installed at the right end of the spring 10 .

[0026] By arranging the spring 10 and the semicircular slider 11, it can be achieved that when the door is subjected to a large force, the door suction base can provide a buffering stress to reduce damage to the bottom of the door.

[0027] Among them, a fixing seat 12 is provided on the right side of the chassis 1, a rubber plug 13 is fixedly installed on the left side of the fixing seat 12, a cylindrical groove 14 is opened at the bottom of the left end of the rubber plug 13, a spring 15 is fixedly installed inside the cylindrical groove 14, and an iron column 16 is fixedly installed at the bottom end of the spring 15.

[0028] By providing a cylindrical groove 14 at the bottom of the rubber plug 13 and a spring 15 installed inside the cylindrical groove 14, movement can be achieved under the influence of external force, and once the external force is lost, the iron column 16 will return to its original position through the elastic force of the spring 15.

[0029] The rubber plug 13 is made of rubber, and when the rubber plug 13 is driven to move, it can contact the two gears 6 at the same time.

[0030] By setting the rubber plug 13 to be made of rubber, it can be achieved that when it is moved to the “U”-shaped baffle 5 , it can contact the two gears 6 at the same time.

[0031] The two wire steels 7 pass through the middle of the two gears 6 respectively, and the thread directions of the surfaces of the two wire steels 7 are opposite.

[0032] By arranging two wire steels 7 to pass through the middle of the two gears 6 respectively, it can be achieved that when the two gears 6 rotate simultaneously, the wire steels 7 will move in the same direction up and down.

[0033] The magnetic block 8 is made of a magnet, and when the magnetic block 8 moves to contact the suction seat 2, the iron column 16 is sucked downward.

[0034] By setting the magnetic block 8 to be made of magnet, it can be achieved that when the magnetic block 8 moves upward to contact the suction seat 2, the iron column 16 will be affected by the magnetic force of the magnetic block 8 to move downward.

[0035] The iron column 16 is made of iron, and when the iron column 16 is sucked downward, it contacts the inner surface of the waist-shaped groove 3 .

[0036] By setting the iron column 16 to be made of iron, the iron column 16 can be affected by the magnetic force of the magnetic block 8 to move downward. By setting the iron column 16 to contact the inner surface of the waist-shaped groove 3 when being adsorbed downward, the position of the iron column 16 can be fixed by the waist-shaped groove 3 so that the door cannot rebound.

[0037] The outer surface of the semicircular slider 11 is covered with a rubber pad, and the semicircular slider 11 contacts the surface of the chassis groove 9 when moving left and right.

[0038] By arranging a rubber pad on the outer surface of the semicircular slider 11, it can be achieved that when the door is subjected to a large force, the semicircular slider 11 can provide a buffering stress to reduce damage to the bottom of the door.

[0039] The working principle and use process of this utility model:

[0040] When the door is opened, the door drives the fixing seat 12 and the rubber plug 13 to move. When the rubber plug 13 moves toward the inside of the "U"-shaped baffle 5, since the rubber plug 13 is made of rubber, it drives the two gears 6 to rotate at the same time. The rotation of the two gears 6 drives the two wire steels 7 to move upward, and the magnetic block 8 at the bottom of the wire steel 7 also moves upward to contact the top of the rectangular groove 4, thereby adsorbing the iron column 16 downward to contact the magnetic block 8. At this time, the bottom of the iron column 16 is in contact with the waist-shaped groove 3, thereby fixing the door.

[0041] Close the door and push it slightly toward the side of chassis 1. At this time, magnetic block 8 moves to the limit distance. Since rubber plug 13 is made of rubber, wire steel 7 will no longer move upward and gear 6 will no longer rotate. At this time, pull the door back toward the door frame, and the two gears 6 rotate in opposite directions. Wire steel 7 drives magnetic block 8 to move downward, causing the magnetic force to weaken. The elastic force of spring 2 15 causes iron column 16 to rebound, thereby achieving the closure of the door.

[0042] A chassis groove 9 is provided, a spring 10 is installed on the surface of the chassis groove 9, and a semicircular slider 11 is installed at the end of the spring 10 away from the chassis 1. The rubber pad sleeved on the surface of the semicircular slider 11 can ensure that when the door is subjected to a large force, the door suction base can provide buffering stress to reduce damage to the bottom of the door.
