Description

Technical Field

[0001] The utility model relates to the technical field of door stoppers, in particular to a door stopper structure with the function of preventing the door from sagging. Background Art

[0002] The door stopper, also commonly known as the door bumper, is a device that holds the door in place after it is opened to prevent it from closing due to wind or being touched. Door stoppers are divided into two types: permanent magnet door stoppers and electromagnetic door stoppers. Permanent magnet door stoppers are generally used in ordinary doors and can only be manually controlled; electromagnetic door stoppers are used in electric control doors and windows such as fire doors, and have both manual control and automatic control functions.

[0003] In the existing door stopper structure, the suction head part (installed on the door panel) does not have a supporting effect on the door. Over time, the door will sag, which affects the use effect of the door. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and propose a door stopper structure with the function of preventing the door from sagging.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A door stopper structure with the function of preventing the door from sagging, which is composed of a U-shaped cover, a pulley and a fixing plate. An installation plate and a magnetic sheet are installed on the U-shaped cover. The pulley is rotatably installed inside the U-shaped cover. A quarter sphere is provided on the fixing plate, and a magnetic block is provided on the sphere.

[0006] As a further description of the above technical scheme:

[0007] A through hole one is provided on the installation plate, and the installation plate is fixed on the door body through the cooperation of the through hole one and a screw.

[0008] As a further description of the above technical scheme:

[0009] A through hole two is provided on the fixing plate, and the fixing plate is fixed on the ground through the cooperation of the through hole two and a screw.

[0010] As a further description of the above technical scheme:

[0011] The magnetic sheet is adapted to the magnetic block.

[0012] The utility model has the following beneficial effects:

[0013] The installation plate is fixed on the door body through the cooperation of the through hole one and a screw, and the pulley slides on the ground, thus ensuring the support for the door body and avoiding the phenomenon of the door sagging after long-term use.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Refer to Figures 1 to 3 As shown, the present utility model adopts the following technical solutions: A door stopper structure with anti-door sag, which is composed of a U-shaped cover 1, a pulley 2 and a fixing plate 3. A mounting plate 4 and a magnetic attraction piece 5 are installed on the U-shaped cover 1. The pulley 2 is rotatably installed in the U-shaped cover 1. A quarter sphere 6 is provided on the fixing plate 3, and a magnetic attraction block 7 is provided on the sphere 6.

[0021] A first through hole 8 is provided on the mounting plate 4, and the mounting plate 4 is fixed on the door body through the cooperation of the first through hole 8 and a screw.

[0022] The fixing plate 3 is provided with a second through hole 9, and the fixing plate 3 is fixed on the ground through the cooperation of the second through hole 9 and a screw.

[0023] The magnetic attraction piece 5 is adapted to the magnetic attraction block 7.

[0024] Usage steps:

[0025] The mounting plate 4 is fixed on the door body through the cooperation of the first through hole 8 and a screw, and the pulley 2 is made to slide on the ground, thus ensuring the support for the door body and further avoiding the phenomenon of the door sagging after long-term use. The fixing plate 3 is fixed on the ground through the cooperation of the second through hole 9 and a screw. When in use, when the door is opened, the magnetic attraction piece 5 and the magnetic attraction block 7 coincide.

[0026] The above description is about the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural manners and embodiments similar to the technical solution without departing from the purpose of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
