An electric retractable door stopper

Abstract

The invention discloses an electric stretchable door stopper, wherein a stretchable device comprises a spiral driving rod (5), a spiral stretchable cover (1) and a plastic sliding sleeve (3); the spiral stretchable cover (1) is provided with a limiting anti-roll bar (4), the plastic sliding sleeve (3) is provided with a limiting anti-roll groove (13), the spiral driving rod (5) is connected with the spiral stretchable cover (1) through a thread, and the plastic sliding sleeve (3) is installed outside the spiral stretchable cover (1). Limiters (2) and (14) are arranged at both ends of the limiting anti-roll groove (13), a power supply (11) is connected with a switch (12), a motor (10) is fixedly connected with a gear (9), and a gear (6) is fixedly arranged on the spiral driving rod (5); the motor (10) drives the gear (9) to rotate, the gear (9) drives the gear (6) to rotate and the gear (6) drives the spiral driving rod (5) to rotate so as to further drive the spiral stretchable cover (1) to stretch. The door stopper is controlled to stretch by electric control and has the characteristics of safety, impact resistance and the like.

Description

technical field [0001] The invention relates to a door stopper, in particular to an electric telescopic door stopper. 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 leaf after it is opened, so as to prevent the wind from blowing or touching the door leaf and closing it. Due to certain needs in daily life, the door is required to be in an open state all the time. The door stopper is widely used in furniture as a tool for fixing the door panel. In the prior art, the door stopper is generally divided into two parts, one part is installed in the On the door, a part is installed on the wall or on the ground, and the door is fixed by the action of magnetic force. But there are following disadvantages in the prior art: (1) Since the door stop protrudes from the wall, the ground or the door panel when installed, it will cause accidental tripping when pedestrians walk by, especially...

AI Technical Summary

Problems solved by technology

But there are following disadvantages in the prior art: (1) Since the door stop protrudes from the wall, the ground or the door panel when installed, it will cause accidental tripping when pedestrians walk by, especially when infants crawl or play indoors, Protrusions are easy to cause bumps and injuries to infants and young children. Therefore, there is a great potential danger in the existing door stoppers; (2) most of the door stoppers are installed under the door panels. It produces a great impact force, and in the process of opening the door, it will produce a great pulling force, the force is uneven, the bearing force of the impact force and the pulling force is relatively small, and it is often easy to damage the door and the door frame; (3 ) Due to the limitations of the installation position of the existing door stoppers, after the door stoppers are installed, they all protrude from the door panels, walls or ground, and the decorative effect is poor, which affects the beauty of the indoor layout. In addition, when it is necessary to clean the indoor sanitation, it will also hinder cleanup

[0003] With the progress of society, door stoppers are more and more widely used in people's lives. However, the types of door stoppers on the market are limited, and the structure is limited. In addition to continuous modification of the appearance, there is no breakthrough for the internal structure. Innovative, and the installation generally protrudes from the wall, floor or door panel
