Door stopper easy to mount and capable of effectively protecting door plate

Abstract

The invention discloses a door stopper easy to mount and capable of effectively protecting a door plate. The door stopper comprises a cover plate (1). A blind hole is formed in one side of the cover plate (1). A bottom plate (2) fixed with a wall face is arranged in the blind hole. The cover plate (1) and the bottom plate (2) are in threaded connection. A pipe body (3) is arranged on the other side of the cover plate (1), an inward convex ring (4) is arranged at the end of the pipe body (3), a piston (5) is arranged in the pipe body (3), and the pipe body (3) and the piston (5) are in threadedconnection. A spring (6) is arranged between the piston (5) and the cover plate (1). A connecting rod (7) penetrating the convex ring (4) is arranged on the piston (5). A ball head (8) is arranged atthe end of the connecting rod (7) and is connected with a magnetic plate through a bowl-shaped body (9). A steel plate (11) fixed to the door plate is arranged on one side of the magnetic plate. Thedoor stopper has the advantage of being low in mounting difficulty and capable of effectively protecting the door plate.

Description

technical field [0001] The invention belongs to the field of door stoppers for installation, in particular to a door stopper which is easy to install and can effectively protect a door panel. Background technique [0002] The door stopper is also commonly known as the door touch, and it is also a device that absorbs and positions the door panel after it is opened, so as to prevent the wind from blowing or touching the door panel and closing it. Such as figure 2 As shown, the door stopper is divided into a magnetic part fixed on the wall and a non-magnetic part fixed on the door panel. The magnetic part is a magnetic ball head, and the magnetic ball head is fixed on the wall through the mounting seat. The magnetic part is provided with a spherical concave surface matched with the magnetic ball head. In order for the door panel to be firmly adsorbed on the wall, when the door panel is opened, the magnetic ball head needs to be exactly in the spherical concave surface. At thi...

Problems solved by technology

In order for the door panel to be firmly adsorbed on the wall, when the door panel is opened, the magnetic ball head needs to be exactly in the spherical concave surface. At this time, the magnetic ball head and the spherical concave surface are in a state of surface contact, and the strength of the magnetic adsorption will be the greatest. It puts forward great requirements on the installation accuracy of the door stopper, and it is difficult for workers to accurately install the door stopper in actual operation.

The existing door stopper has a buffer spring, the buffer spring is located inside the non-magnetic part, and the length is relatively short. When the door panel is opened at a fast speed, the buffer spring is difficult to play a buffering role, and the door panel is relatively easy to be damaged by collision

[0003] Therefore, the existing door stopper has the defects of great difficulty in installation and inability to effectively protect the door panel
