Description

Technical Field

[0001] The invention relates to the technical field of door stoppers, and in particular to a household gas door stopper. Background Art

[0002] Door stoppers are also called door bumpers or door stops. They are installed on the door leaf, skirting or floor to fix the door leaf when it is open and to prevent the handle from damaging the wall. Common types include: foot-operated door stoppers, magnetic door stoppers, one-way door support door stoppers and industrial hinge door stoppers.

[0003] Among them, the door fixing method of the foot-operated door stopper requires downward pressure, and the size of its connection force is caused by the elastic force of the spring. The advantage is that it can be adjusted at multiple angles. The main disadvantage is that the elastic force is insufficient and the positioning effect is weak. The magnetic door stopper mainly uses magnetic force for adsorption, but its position is relatively single and fixed, and the angle cannot be adjusted. Although the one-way door support door stopper is flexible and can be positioned at multiple angles, its unidirectionality and connection strength are insufficient. The industrial hinged door stopper requires continuous power supply and has a strong driving force. It is suitable for use in various relatively external environments such as community courtyard doors. Its circuit requires a large space for installation and is not suitable for small spaces in furniture and small-scale indoor doors. Therefore, it is urgent to design a new technical solution to comprehensively solve the problems existing in the existing technology. Summary of the invention

[0004] The purpose of the present invention is to provide a household gas door stopper which can effectively solve the problems of weak positioning effect of existing foot-operated door stoppers, inability to adjust the angle of magnetic door stoppers, inability of one-way door support door stoppers to work in the opposite direction, and large footprint of industrial hinged door stoppers and inconvenience in indoor use.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:
