Description

Technical Field

[0001] The present invention relates to the field of building structures, and particularly to a door structure and a pressure-bearing house. Background Art

[0002] In the plateau environment, the air is thin and the air pressure is low, which causes people from low altitude areas to be prone to altitude sickness in the plateau environment. And people who have lived in high altitude areas for a long time also face problems such as oxygen intoxication when they first arrive in low altitude areas. A pressure-bearing building can establish an independent environmental system with a different air pressure from the surrounding environment to solve the problem of environmental adaptation.

[0003] The problems existing in the pressure-bearing door in the transition area of the existing pressure-bearing buildings are as follows: 1. Before opening the door, it is necessary to first adjust the indoor pressure. After the pressures on both sides of the door are equal, then open the door. This kind of structure has a long waiting time, is difficult to achieve rapid door opening, and cannot meet the needs of people to enter and exit quickly; 2. The micro-pressure difference pressure-bearing door does not need to wait for pressure adjustment, but when opening, since air will flow from the high-pressure space to the low-pressure space, when the staff enters the door, they will be directly blown by the air flow in the low-pressure area, causing discomfort to the human body.

[0004] In summary, there is an urgent need for a door structure and a pressure-bearing house to solve the problems of slow opening and closing of the pressure-bearing door and the direct blowing of air flow on the human body in the prior art. Summary of the Invention

[0032] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0033] Embodiment:

[0034] A door structure includes a door body 1, a telescopic assembly, and a telescopic windshield 2, as Figures 1 to 3 shown, specifically as follows:

[0035] The door body 1 is arranged on the wall 12, and the door body 1 is used for connecting and closing two spaces.

[0036] The telescopic assembly includes a first telescopic member 3 and a second telescopic member 4. The first telescopic member 3 is slidably arranged on the wall 12, and the telescopic end of the first telescopic member 3 is fixedly connected to the door body 1. The door body 1 is driven by the first telescopic member 3 to move in the horizontal first direction (i.e., the door entering direction). One end of the second telescopic member 4 is fixed on the wall 12, and the other end is fixedly connected to the door body 1. The door body 1 is driven by the second telescopic member 4 to move in the horizontal second direction (i.e., the left - right direction in front of the human body). The first direction and the second direction are perpendicular to each other in the horizontal plane. That is, when entering the door, the door body 1 is pushed forward by the first telescopic member 3, and the second telescopic member 4 drives the door body 1 to move to the right or left, so as to realize the opening of the door body 1 (when the door body 1 needs to be closed, it moves along the original path, that is, an inverted L - shaped movement trajectory). The first telescopic member 3 and the second telescopic member 4 are both electric push rods, pneumatic rods, hydraulic cylinders or transmission chains.

[0037] The first telescopic member 3 is slidably arranged on the wall 12 in the following way: The wall 12 is provided with a chute 12.a along the second direction, and the first telescopic member 3 is slidably arranged in the chute 12.a and can follow the door body 1 to slide in the second direction, so as to avoid interfering with the left - right movement of the door body 1. Preferably, the cross - sectional shape of the chute 12.a is an inverted T - shape, which can prevent the first telescopic member 3 from disengaging from the chute 12.a when pulling the door body 1 (that is, the first telescopic member 3 can only slide in the length direction of the chute 12.a).

[0038] The telescopic windshields 2 are provided in multiple groups (for example, four groups). Preferably, multiple groups of telescopic windshields 2 surround and form a ring (rectangular ring or circular ring, specifically selected according to the shape of the door body 1) around the first direction. The telescopic windshields 2 are horizontally and fixedly arranged on one side of the door body 1 close to the wall 12. The telescopic windshields 2 are used to block the airflow and prevent the airflow in the high-pressure space from directly blowing on the human body when entering the door. Specifically: The telescopic windshield 2 includes a third telescopic member and two windshields; the two windshields are slidably connected, and the sliding connection method is, for example, the cooperation of a T-shaped protrusion and a T-shaped groove; the two windshields are both horizontally arranged, and the end of one windshield is fixed on the side of the door body 1 where people enter; both ends of the third telescopic member are respectively connected to the two windshields, and the third telescopic member can drive the windshield close to the wall 12 to perform a sliding telescopic action in the first direction; when the staff enters the door, the door body 1 is pushed forward in the first direction, and at the same time, the windshield close to the wall 12 is in the extended state, so as to block the airflow. When the door body 1 is closed, the windshield close to the wall 12 is in the retracted state; by setting the telescopic windshield, the opening and closing states of the door body 1 can be matched. The third telescopic member refers to existing elastic members or electric push rods.

[0039] Preferably, a first seal 10 is provided on the end face of the windshield close to the wall 12 (the shape of the first seal 10 is strip-shaped, rectangular ring-shaped or circular ring-shaped, and preferably its shape is selected according to the shape formed by surrounding multiple groups of telescopic windshields 2). When the door body 1 is closed, the first seal 10 can be in contact with the wall surface of the wall 12 under the drive of the door body 1, so as to achieve the primary seal on the inner and outer sides of the door body 1.

[0040] Preferably, a second seal 11 is provided on one side of the door body 1 close to the wall 12 (the shape of the second seal 11 is preferably the same as that of the first seal 10). When the door body 1 is closed, the second seal 11 can be in contact with the inner wall surface of the wall 12 under the drive of the door body 1, so as to achieve the secondary seal on the inner and outer sides of the door body 1. The first seal 10 and the second seal 11 refer to existing seal structures, and the first seal 10 and the second seal 11 are preferably made of flexible materials.

[0041] The door structure of this embodiment further includes a guiding structure, which is used for guiding the door body 1 during movement. Specifically: The guiding structure includes a guiding beam 5 and guiding members; the guiding beam 5 is fixed on the ground or the wall surface of the wall 12, and a guiding groove 5.a for guiding the door body 1 is provided on the guiding beam 5. The trajectory (i.e., the opening direction) of the guiding groove 5.a is the same as the movement trajectory of the door body 1, both of which are inverted L-shaped. The guiding members are connected to the upper end or the lower end of the door body 1, and the guiding members are located in the guiding groove 5.a. When the door body 1 moves, the guiding members move in the guiding groove 5.a along with the door body 1, so as to achieve the guiding of the door body 1.

[0042] Preferably, the present embodiment is provided with two groups of guide structures, which are respectively arranged at the upper end and the lower end of the door body 1, wherein the guide member of the guide structure arranged at the upper end is a slide rail 6, and the slide rail 6 is slidably arranged in the guide groove 5.a; the guide member of the guide structure arranged at the lower end is a rolling body 7 (ball), and the rolling body 7 is arranged in the guide groove 5.a and can roll in the guide groove 5.a with the door body 1.

[0043] The upper or lower end of the door body 1 is provided with a dust removal brush 8, which is provided corresponding to the guide groove 5.a. When the door body 1 moves, the dust removal brush 8 can be driven to move, thereby removing foreign matter that may exist in the guide groove 5.a, keeping the guide groove 5.a clean, reducing the wear between the rolling body 7 and the guide groove 5.a, and avoiding the door body 1 from jamming during movement. In this embodiment, dust removal brushes 8 are preferably provided on the outer sides of the rolling body 7 in the front, rear, left, and right directions in the horizontal direction.

[0044] The guide beam 5 is provided with a limiting portion, and a flexible buffer 9 (such as rubber) is provided at the end of the limiting portion. When the door body 1 moves in the first direction, it can conflict with the flexible buffer 9. The limiting portion and the flexible buffer 9 are used for buffering and limiting the door body 1 in the first direction.

[0045] The door structure of this embodiment also includes a control structure and a door switch button; the control structure is used to control the first telescopic member 3, the second telescopic member 4 and the third telescopic member respectively; the door switch button is arranged on the wall 12, the switch button is electrically connected to the control structure, and the switch button sends instructions to the control structure, and the control structure controls the corresponding component actions to realize the opening and closing of the door 1. The control structure refers to the prior art.

[0046] This embodiment also discloses a pressure-bearing house (which may be a positive pressure house or a negative pressure house, and this embodiment is preferably a positive pressure house), comprising a house body 13, a transition area 14, and the door structure;

[0047] In this embodiment, door structures are arranged on the walls of the main body 13 of the house and the walls of the transition zone 14. The multiple door structures are used to connect the outside world with the transition zone and between the transition zone and the main body of the house. That is, the staff can pass between the outside world and the transition zone 14 and between the transition zone and the main body of the house 13 through the multiple door structures. A preferred specific structure is as follows Figure 1 : The transition zone 14 is arranged in the main body of the house 13, and a group of door structures (for communication between the outside world and the transition zone 14) are provided on the wall connecting the transition zone 14 and the main body of the house 13, and a group of door structures (for communication between the transition zone and the main body of the house 13) are also provided on the wall of the transition zone 14.

[0048] The transition area 14 in this embodiment can be divided into multiple single transition areas, and adjacent single transition areas are connected through a door structure; in order to be more conducive to sealing, the door structures in this embodiment are all located on the side with greater pressure in the two spaces, so that the space with greater pressure can use the pressure difference to press the door structure tightly against the wall surface of the wall body 12.

[0049] The working principle of the door structure in this embodiment is as follows:

[0050] When the staff needs to enter the door:

[0051] First step, press the switch button, and the control structure controls the first telescopic member 3 to act, and the first telescopic member 3 pushes the door body 1 forward;

[0052] Second step, during the forward sliding of the door body 1, the third telescopic member acts, and the telescopic wind baffle 2 gradually extends. Air flows from the high-pressure space to the low-pressure space, and the telescopic wind baffle 2 blocks the air flow, thereby changing its flow direction and avoiding directly blowing on the human body;

[0053] Third step, after the first telescopic member 3 acts in place, the second telescopic member 4 acts, pulling the door body 1 horizontally to the right. When the second telescopic member 4 acts in place, the door body 1 is opened, and personnel can quickly enter and exit.

[0054] After the staff enters the door and needs to close the door body 1:

[0055] First step, press the switch button, and the control structure controls the second telescopic member 4 to act, pushing the door body 1 horizontally to the left. After the second telescopic member 4 acts in place, the first telescopic member 3 acts, pulling the door body 1 backward;

[0056] Second step, during the backward movement of the door body 1, the third telescopic member acts, and the telescopic wind baffle 2 gradually contracts. When the first telescopic member 3 acts in place, the telescopic wind baffle 2 also contracts in place, and the first seal 10 and the second seal 11 are in contact with the wall body 12, and the door body 1 is closed.

[0057] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
