A magnetically adjustable door stopper

Abstract

The invention provides a magnetic adjustment door stopper which comprises a fixing base, a mounting head, an adjusting head and a fixing block, wherein the mounting head is assembled at the upper part of the fixing base and is in the shape of a horizontal cylinder, a threaded hole is machined in the rear part of the mounting head, and a spherical groove is axially machined in the front part of the mounting head and is communicated with the threaded hole in a through manner; the adjusting head is in the shape of a stepped cylinder, and an outer thread is machined on the small-diameter outer circle of the front part of the adjusting head; a magnetic block is fixed at the front part of the adjusting head, and the front part of the adjusting head is in threaded connection with the rear part of the mounting head; the fixing block is assembled at the lower part of the rear side of a door plate, and the horizontal extending end part of the fixing block is spherical. People can rotate the adjusting head to drive the magnetic block to move back and forth along the mounting head, so that the suction force of the magnetic block to the fixing block can be adjusted and the purpose of adjusting the suction force of the door plate can be achieved.

Description

technical field [0001] The invention relates to the technical field of door stoppers, in particular to a magnetically adjustable door stopper. Background technique [0002] Door stopper, also commonly known as door stopper, is a device that holds the door panel in position after it is opened. It can prevent the door panel from being closed due to wind or touch. Nowadays, door stoppers usually use magnetic adsorption. The magnitude of the magnetic force is fixed and cannot be changed once it is generated. Therefore, once the current door stopper is assembled, its suction force is completely determined and cannot be changed. At this time, if the force of the door stopper is found to be too large or too small, the door stopper can only be replaced. Very inconvenient. And now the fixed block on the door panel usually touches the magnetic block in a collision mode, and the magnetic block will be demagnetized when it is subjected to a relatively severe collision, so that the magn...

Problems solved by technology

The magnitude of the magnetic force is fixed and cannot be changed once it is generated. Therefore, once the current door stopper is assembled, its suction force is completely determined and cannot be changed. At this time, if the force of the door stopper is found to be too large or too small, the door stopper can only be replaced. very inconvenient

Moreover, the fixed block on the door panel is usually in contact with the magnetic block in a collision manner. The magnetic block will demagnetize when it is subjected to a relatively severe collision, which makes the magnetism of the magnetic block smaller and the fixing force of the door stopper decreases.
