An inflatable door, an inflatable door assembly, and an inflatable building

Abstract

This invention discloses an inflatable door, an inflatable door assembly, and an inflatable building. The inflatable door includes a door-shaped airbag and an elastic element. The door-shaped airbag is vertically arranged in the left-right direction, and an installation strip is horizontally arranged at the upper end of the door-shaped airbag in the left-right direction. A rigid counterweight strip is horizontally arranged at the lower end of the door-shaped airbag in the left-right direction. An inflation port communicating with the interior of the door-shaped airbag is provided on the door-shaped airbag. The elastic element is disposed inside the door-shaped airbag, and its two ends are connected to the installation strip and the counterweight strip, respectively. The elastic force of the elastic element drives the counterweight strip to move upward. Thus, after air is filled into the door-shaped airbag, the door-shaped airbag inflates. When the door-shaped airbag inflates, its lower end moves downward under the weight of the counterweight strip, overcoming the elastic force of the elastic element, thereby achieving the closing action. When the door is opened, the air inside the door-shaped airbag is discharged, at which point the door-shaped airbag contracts. At the same time, the counterweight strip moves upward under the elastic force of the elastic element, thereby achieving the opening action.

Description

Technical Field

[0001] This invention belongs to the field of inflatable buildings, and particularly relates to an inflatable door, an inflatable door assembly, and an inflatable building. Background Technology

[0002] Inflatable buildings are characterized by their large size, strong structural stability, and ease of assembly and disassembly. They are used in fields such as sports stadiums and logistics warehouses. The doors of inflatable buildings mostly adopt single-layer membrane structures and metal frame embedded structures. Single-layer membrane structures have low strength and poor thermal insulation, making them unsuitable for long-term use. Metal frame embedded doors have high structural strength and strong mechanical properties, but the door structure has a large storage volume, making it difficult to transport and install. CN109404035A "Inflatable Air Door" discloses an inflatable air door, but its opening and closing are relatively cumbersome. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide an air valve with a simple structure and convenient opening and closing.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: an inflatable gate, comprising a gate-shaped airbag and an elastic element, wherein the gate-shaped airbag is vertically arranged in the left-right direction, and an mounting strip is horizontally arranged at the upper end of the gate-shaped airbag in the left-right direction; a rigid counterweight strip is horizontally arranged at the lower end of the gate-shaped airbag in the left-right direction; an inflation port communicating with the interior of the gate-shaped airbag is provided on the gate-shaped airbag; the elastic element is disposed inside the gate-shaped airbag, and both ends of the elastic element are respectively connected to the mounting strip and the counterweight strip; the elastic force of the elastic element is used to drive the counterweight strip to move upward; and air is inflated inside the gate-shaped airbag to overcome the elastic force of the elastic element and inflate the gate-shaped airbag.

[0005] The beneficial effects of the above technical solution are as follows: After air is filled into the door-shaped airbag, the airbag inflates. When the airbag inflates, its lower end moves downward under the weight of the counterweight bar, overcoming the elastic force of the elastic element, thus achieving the closing action. When opening the door, the gas inside the airbag is expelled, and the airbag contracts. At the same time, the counterweight bar moves upward under the elastic force of the elastic element, thus achieving the opening action. In addition, since the air-filled door is filled with gas when closed, it has good heat preservation performance.

On the sides of the mounting strip and the counterweight strip close to each other, a plurality of the pulleys are respectively installed at intervals in the left-right direction, and the plurality of pulleys on the mounting strip and the counterweight strip are staggered. The elastic rope bypasses the plurality of pulleys in a snake shape, and both ends of the elastic rope are respectively connected to the mounting strip or the counterweight strip.

[0011] The beneficial effects of the above technical solution are as follows: Its structure is simple, and when the air-inflated door is opened, the counterweight strip moves upward more smoothly and will not tilt.

[0012] The second object of the present invention is to provide an air-inflated door assembly with a simple structure and convenient opening and closing.

[0013] In order to achieve the above object, the technical solution of the present invention is as follows: An air-inflated door assembly includes a door frame, an air pump and the air-inflated door as described above. The door frame is an n-shaped frame or a "mouth" - shaped frame vertically arranged in the left-right direction. The air-inflated door is arranged inside the door frame, and the mounting strip is connected to the door frame. The left and right sides of the air-inflated door are flush with the left and right sides inside the door frame. The inflation port is connected to the air pump through an electric valve.

[0035] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0036] Example 1

[0037] like Figure 1 As shown, this embodiment provides an inflatable gate, including a gate-shaped airbag 11 and an elastic element 12. The gate-shaped airbag 11 is vertically arranged in the left-right direction, and an mounting strip 111 is horizontally arranged at the upper end of the gate-shaped airbag 11 in the left-right direction. A rigid counterweight strip 112 is horizontally arranged at the lower end of the gate-shaped airbag 11 in the left-right direction. The gate-shaped airbag 11 has an inflation port 113 communicating with its interior. The elastic element 12 is disposed inside the gate-shaped airbag 11, and its two ends are respectively connected to the mounting strip 111 and the counterweight strip 112. The elastic force of the elastic element 12 is used to drive the airbag. As the counterweight 112 moves upward, the door-shaped airbag 11 is inflated to overcome the elastic force of the elastic element 12 and expand. Thus, after air is introduced into the door-shaped airbag, it expands. When the door-shaped airbag expands, its lower end moves downward under the weight of the counterweight, overcoming the elastic force of the elastic element, thereby closing the door. When opening the door, the air is expelled from the door-shaped airbag, causing it to contract. At the same time, the counterweight moves upward under the elastic force of the elastic element, thereby opening the door. In addition, since the air-expanding door is filled with gas when closed, it has good heat preservation performance.

[0038] like Figure 2 As shown in the above technical solution, the portal-shaped airbag 11 has multiple tie plates 13 arranged vertically in the middle of its interior, spaced apart in the left and right direction. The front and rear sides of the tie plates 13 are connected to the front and rear sides of the portal-shaped airbag 11, respectively. There are gaps between the two ends of the tie plates 13 and the mounting strip 111 and the counterweight strip 112. By setting tie plates inside the portal-shaped airbag, the front and rear sides of the portal-shaped airbag can be prevented from bulging outward after inflation. After setting tie plates, the front and rear sides of the portal-shaped airbag are bound by the tie plates to form a plate shape as a whole after inflation.

[0039] In the above technical solution, the elastic member 12 includes an elastic cord 121 and a plurality of pulleys 122. On one side of the mounting strip 111 and the counterweight strip 112 that are close to each other, a plurality of the pulleys 122 are installed at intervals in the left-right direction, and the plurality of pulleys 122 on the mounting strip 111 and the counterweight strip 112 are staggered. The elastic cord 121 bypasses the plurality of pulleys 122 in a serpentine shape, and both ends of the elastic cord 121 are respectively connected to the mounting strip 111 or the counterweight strip 112. Its structure is simple, and when the inflatable door opens, the counterweight strip moves upward more smoothly and will not tilt.

[0040] In this embodiment, a pressure sensor is provided at the lower end of the mounting strip inside the door-shaped airbag, and the pressure sensor is used to sense the pressure inside the door-shaped airbag.

[0041] Embodiment 2

[0042] Same as Embodiment 1, the difference is that, as Figure 3 shown, in the above technical solution, the elastic member 12 includes a plurality of elastic cords 121. The plurality of elastic cords 121 are all vertically arranged and distributed at intervals in the left-right direction. Both ends of the elastic cord 121 are respectively connected to the mounting strip 111 and the counterweight strip 112. Its structure is simple, and the plurality of elastic cords cooperate together to apply an upward acting force to the counterweight strip, so as to provide power when the inflatable door opens.

[0043] Embodiment 3

[0044] As Figures 4-7 shown, this embodiment provides an inflatable door assembly, including a door frame 2, an air pump 3, and the inflatable door 1 as described in Embodiment 1 or Embodiment 2. The door frame 2 is an n-shaped frame or a "mouth" - shaped frame vertically arranged in the left - right direction. The inflatable door 1 is arranged inside the door frame 2, and the mounting strip 111 is connected to the door frame 2. The left and right sides of the inflatable door 1 are flush with the left and right sides inside the door frame 2. The inflation port 113 is connected to the air pump 3 through an electric valve 31. Its structure is simple, and when the inflatable door is inflated inside the door frame, it closes, and when it exhausts, it opens. Its opening and closing are convenient, and the heat preservation effect is good.

[0045] In the above technical solution, the inflation port 113 is arranged in the middle of the mounting strip 111, and the air pump 3 is embedded in the upper end of the door frame 2. Its structure is simple, and the degree of integration is high.

[0046] In the above technical solution, chutes 21 are vertically arranged on both sides inside the doorframe 2. Both sides of the counterweight bar 112 extend into the corresponding chutes 21 on each side. The counterweight bar 112 can slide up and down along the doorframe 2, thus preventing the air-inflated door from swaying back and forth relative to the doorframe when closed. Roller wheels 1121 are installed at both ends of the counterweight bar. The roller wheels 1121 at both ends of the counterweight bar respectively extend into the two chutes and are in rolling contact with the chutes, which can reduce the frictional resistance between the counterweight bar and the doorframe when the counterweight bar moves up and down.

[0047] In the above technical solution, the mounting bar 111 and the doorframe 2 are integrally formed, and its structure is simple.

[0048] In the above technical solution, the doorframe 2 is an airbag component (that is, the doorframe 2 is an "n"-shaped airbag or a "mouth"-shaped airbag. An inflation interface can also be provided thereon, and a valve is provided at the inflation interface. After inflation, it can be left unattended for a long time, unless the valve needs to be opened for exhaust when deflating and packing for storage), so that the entire inflatable door assembly is convenient to store.

[0049] Of course, a controller can also be added. The air pump, the electric valve, and the pressure sensor are all electrically connected to the controller. Among them, two pressure values can be set through the controller, one is the opening set value and the closing set value. Among them, the closing set value (set according to the specific situation of the air-inflated door. When the internal pressure value reaches the closing set value, it can be determined that the gas in the door-shaped airbag is full) is greater than the opening set value (the opening set value can be set to normal pressure).

[0050] The electric valve can adopt a solenoid valve (the air outlet of the air pump is connected to the inflation port, and the solenoid valve is arranged between the two). When the air-inflated door is closed, the electric valve is opened, and the air pump is started. The air pump inflates the door-shaped airbag. When the pressure sensed by the pressure sensor reaches the closing set value, the electric valve is closed, and the air pump stops running. At this time, the air-inflated door is closed. When the air-inflated door needs to be opened, the electric valve is opened, and the air pump can reverse (at this time, the air pump is similar to an air extraction pump), which extracts the gas in the door-shaped airbag. At this time, the door-shaped airbag shrinks, and under the action of the elastic member, the counterweight bar moves upward, thereby opening the air-inflated door. When the pressure sensed by the pressure sensor reaches the opening set value, the air pump stops running.

[0051] Of course, two controllers can be provided, which are respectively used to be set indoors and outdoors (similar to an access control switch). The door can be opened / closed respectively from indoors and outdoors. The controller can adopt an arm series single-chip microcomputer.
