A durable door suction rod

Abstract

A durable door suction rod comprises a clamping shell (1) and a sucker body (8). The right end of the sucker body (8) is connected with a rod shaft (2). A rubber anti-collision sleeve (18) is arranged on the outer surface of the sucker body (8). The rubber anti-collision sleeve (18) wraps the left half part of the sucker body (8). The rubber anti-collision sleeve (18) and the sucker body (8) are glued and fixed. The rod shaft (2) is connected with the clamping shell (1) through a stretching structure (3). A buffer shaft (4) is arranged in the center of the right end of the rod shaft (2). A buffer space (5) used for arranging the buffer shaft (4) is formed in the clamping shell (1). A pressure air space (9) is formed in the part, located on the right side of the buffer space (5), in the clamping shell (1). A passing cavity (6) which communicates with the pressure air space (9) and the buffer space (5) is formed between the pressure air space (9) and the left side part of the buffer space (5). The part, located on the left side part of the buffer space (5), of the passing cavity (6) is provided with a set of ejection heads (7).

Description

technical field [0001] The present invention relates to a durable door suction rod. Background technique [0002] At present, the use and installation of doors have become an important part of home decoration, and are closely related to people's lives. When people open the door with too much force, over time, the door will cause damage to the wall, and the door itself will collide with the wall. There will also be damage after the door. For this reason, a door suction is usually installed on the wall behind the door. The existing door suction is only fixed on the wall by a top rod, so as to prevent the door from directly contacting the wall, thereby preventing the door from directly contacting the wall. Reduce the damage to the wall, but this kind of door suction does not have a buffering effect. When people use too much force when opening the door, it will still cause the door to collide with the ejector rod, which will cause damage to the door, and the ejector rod is fixed...

Problems solved by technology

[0002] At present, the use and installation of doors has become an important part of home decoration and is closely related to people's lives. When people open the door with too much force, if things go on like this, the door will cause damage to the wall, and the door itself will collide with the wall. Damage will also occur after the door. For this reason, a door stopper is usually installed on the wall behind the door. The existing door stopper is only fixed on the wall by a push rod, thereby preventing the door from directly contacting the wall. Reduce the damage to the wall, but this kind of door stopper does not have a buffering effect. When people open the door with too much force, it will still cause the door to collide with the ejector rod, which will cause damage to the door, and the ejector rod is fixed. Has a buffering effect, so it cannot meet existing usage needs
