Problems solved by technology

[0002] Doors refer to the entrances and exits of buildings or storage devices (such as refrigerators) or devices that can be opened and closed at the entrances and exits. However, in many double-leaf doors, one door has been closed, and when the other door is closed, the closed door will turn slightly, causing the door to be sealed. If it is not tight, it will cause damage to the function of some devices. For example, in a double-door refrigerator, the door of the refrigerator is not tightly sealed, which will lead to the exchange of internal and external air and destroy the storage function of the refrigerator.

Embodiment 1

[0026] Example 1: See Figure 1-5 A double door structure that prevents the door from turning slightly, it includes a box body 1, a first door 2, a second door 3 and an airbag structure 4, a box body 1, a first door 2, a second door 3 and an airbag structure 4 enclosing an inner cavity, the first door 2 is rotatably connected to the left side wall of the box body 1, the second door 3 is rotatably connected to the right side wall of the box body 1, and the airbag structure 4 is arranged on the first door 2 and the second door 3 Between, the upper end of the air bag structure 4 is connected with the inner top wall of the box body 1, the lower end of the air bag structure 4 is connected with the inner bottom wall of the box body 1, and the air bag structure 4 initially has gas inside, which is used to ensure that when one door is closed, the other When a door is closed, the tightness of the closed door.

Embodiment 2

[0037] Embodiment 2: Different from Embodiment 1, the lower end of the airbag structure 4 is rotatably connected to the inner lower end of the box body 1, and the upper end of the airbag structure 4 is detachably connected to the inner top end of the box body 1. It is a kind of prior art, which can facilitate the disassembly of a section of the airbag solution structure 4, and is convenient for storing and taking larger things.

Embodiment 3

[0038] Embodiment 3: see Figure 6 , when different from Embodiment 1, a fourth one-way valve 5 may be provided on the side wall of the box body 1. When the door is closed, when the inner cavity pressure formed between the box body 1 and the door increases, the The fourth one-way valve 5 discharges part of the gas, so that the gas pressure in the inner cavity tends to be stable, which facilitates the closing of the door.

Abstract

The invention relates to the technical field of doors, and discloses a double-door structure capable of preventing a door from slightly rotating. The double-door structure comprises a box main body, a first door, a second door and an air bag structure, wherein an inner cavity is defined by the box main body, the first door, the second door and the air bag structure; the first door is rotatably connected with the left side wall of the box main body, and the second door is rotatably connected with the right side wall of the box main body; the air bag structure is arranged between the first door and the second door, the upper end of the air bag structure is connected with the inner top wall of the box main body, and the lower end of the air bag structure is connected with the inner bottom wall of the box main body; and the air bag structure is internally filled with air at the initial time and is used for guaranteeing the leakproofness of the closed door when one door is closed and the other door is closed.

Description

technical field [0001] The invention relates to the field of doors, in particular to a double door structure that prevents the door from turning slightly. Background technique [0002] Doors refer to the entrances and exits of buildings or storage devices (such as refrigerators) or devices that can be opened and closed at the entrances and exits. However, in many double-leaf doors, one door has been closed, and when the other door is closed, the closed door will turn slightly, causing the door to be sealed. If it is not tight, it will cause damage to the function of some devices. For example, in a double-door refrigerator, the door of the refrigerator is not tightly sealed, which will cause the exchange of internal and external air and destroy the storage function of the refrigerator. Contents of the invention [0003] The invention provides a double-opening door structure that prevents the door from turning slightly, which can solve the above-mentioned technical problems....
