Abstract
The utility model discloses a kind of interior enclosed revolutional shell doors, including door body, the side of door body is hinged on the inner end of doorframe, door body includes the flat part at edge and the lug boss at middle part, lug boss is protruded to the side in oxygen-enriched space, the section of lug boss be it is arc-shaped, the position that doorframe contact with flat part is provided with sealing element, doorframe and flat part sealed connection when closing；Door body is arranged to the flat part that middle part is lug boss and edge, it is acted on lug boss between the pressure in oxygen-enriched space in use, since the setting of lug boss increases the forced area of pressure so that the ability of its anti-air pressure greatly enhances, so that it is not in deformation in long-time use process, and its structure is simple, and it is at low cost；And do not have to directly make it complete sealing effect between doorframe in door body with the gas pressure in oxygen-enriched space by external equipment when sealing.
Description
Technical field
It is the utility model relates to oxygen-enriched space sealing equipment technical field, in particular to a kind of for sealing oxygen-enriched space
Interior enclosed revolutional shell door.
Background technique
Oxygen-enriched space is a kind of warehouse of sealing, and internal oxygen content is higher than the oxygen content in air, and pressure
Higher than external pressure.This device is since internal oxygen content is high, with certain medical care effect.Currently, existing
Oxygen-enriched space sealing door is mostly a slab, and since hermatic door is template, long-time is used, effect of the hermatic door in air pressure
It is lower that certain deformation can occur so that its sealing effect is bad, influence using.
Utility model content
It is good that the technical problem to be solved by the present invention is to provide a kind of sealing effects, is not in its effect in pressure
The interior enclosed revolutional shell door of lower deformation.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows: a kind of interior enclosed revolutional shell door, including
Door body, the side of door body are hinged on the inner end of doorframe, and door body includes the flat part at edge and the lug boss at middle part, lug boss to
The side in oxygen-enriched space is protruded, the section of lug boss be it is arc-shaped, the position that doorframe is contacted with flat part is provided with sealing element, pass
Doorframe and flat part are tightly connected when closing.
Further, the separate one end hinged with doorframe of door body is provided with handle.
Further, its middle part is struck out lug boss by the way of punching press by door body, and edge is flat part.
Further, open angle is 90 ° between door body and doorframe.
Further, airtight connection is completed using the air pressure inside pressure chamber between door body and doorframe.
What the utility model obtained by adopting the above technical scheme have the beneficial effect that by door body be arranged to middle part be lug boss and
The flat part at edge acts on lug boss between the pressure in oxygen-enriched space, in use due to the setting of lug boss
The forced area of pressure is increased so that the ability of its anti-air pressure greatly enhances so that its in long-time use process not
It will appear deformation, and its structure is simple, it is at low cost；And do not have to when sealing by external equipment, directly in oxygen-enriched space
Gas pressure in door body, so that it is completed sealing effect between doorframe.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- door body；2- doorframe；3- flat part；4- lug boss.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
The utility model is further described in conjunction with attached drawing, makes this reality of person of ordinary skill in the field's better implementation
With novel, a kind of interior enclosed revolutional shell door of the utility model embodiment, including door body 1, the side of door body 1 are hinged on doorframe 2
Inner end, the flat part 3 of door body 1 including edge and the lug boss 4 at middle part, lug boss 4 is protruded to the side in oxygen-enriched space, convex
Rise the section in portion 4 be it is arc-shaped, the position that doorframe 2 is contacted with flat part 3 is provided with sealing element, doorframe 2 and flat part 3 when closing
It is tightly connected.
The separate one end hinged with doorframe 2 of the utility model embodiment door body 1 is provided with handle；Door body 1 is using punching press
Its middle part is struck out lug boss 4 by mode, and edge is flat part 3；Open angle is 90 ° between door body 1 and doorframe 2；Door body 1 with
Airtight connection is completed using the air pressure inside pressure chamber between doorframe 2.
Door body 1 is arranged to the flat part 3 that middle part is lug boss 4 and edge by the utility model embodiment, in use process
In act on lug boss 4 between pressure in oxygen-enriched space, due to the setting of lug boss 4 increase the forced area of pressure from
And the ability of its anti-air pressure is greatly enhanced, so that it is not in deformation, and its structure in long-time use process
Simply, at low cost；And do not have to directly be made in door body 1 with the gas pressure in oxygen-enriched space by external equipment when sealing
It completes sealing effect between doorframe 2.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
