Description

Technical Field

[0001] The utility model belongs to the technical field of sealing equipment, and in particular relates to an anti-bending composite sandwich flat plate and an oxygen cabin. Background Art

[0002] With the diversified demands of people for health, micro-pressure oxygen chambers are entering people's field of vision. Micro-pressure oxygen chambers usually provide an oxygen environment slightly higher than normal pressure, providing users with a breathing environment of pure oxygen or high-concentration oxygen, thereby achieving the purpose of treating hypoxic diseases and related diseases. Since the air pressure in the chamber exceeds normal pressure, there are certain requirements for the pressure resistance of the oxygen chamber body material.

[0003] The oxygen chambers currently on the market are mainly medical oxygen chambers. Due to their large size and high pressure inside, the chambers are all round in shape and made of steel. This type of chamber has high strength and is heavy. Some civilian oxygen chambers also use the above design, but civilian oxygen chambers need to be used at home, and the overly bulky design creates obstacles to entry.

[0004] Therefore, how to design a lightweight cabin material and an oxygen cabin is a problem that needs to be solved at present. Utility Model Content

[0005] The utility model provides a bending-resistant composite sandwich flat plate and an oxygen chamber, which solve the problems that the existing oxygen chamber is heavy, large in size and cannot be put into the house.

[0006] In order to solve the above technical problems, the technical solutions adopted by the present utility model are as follows:

[0007] Provided is a bending-resistant composite sandwich flat plate, comprising a base plate and an inner sealing plate, wherein a plurality of reinforcing rib structures are arranged on the surface of the base plate, the inner sealing plate is laid on the reinforcing ribs, and a through beam is arranged between the base plate and the inner sealing plate, wherein the through beam passes through a closed space between the base plate and the inner sealing plate.

[0008] Furthermore, the reinforcing ribs are cross ribs, triangular cross ribs or multi-sided cross ribs.

[0009] Furthermore, the anti-bending composite sandwich plate also includes a connecting seat, which is plugged into the apex of the cross ribs and is in close contact with the inner sealing plate.

[0010] Furthermore, the connecting seat and the inner sealing plate are connected by bolts or by bonding.

[0011] Furthermore, the through beam is a straight bar profile, and the straight bar profile is a solid column-shaped straight bar, or a straight bar profile with a U-shaped or U-shaped cross section.

[0012] Furthermore, the straight bar profile with a U-shaped cross section includes a large U-shaped straight bar profile and a small U-shaped straight bar profile, wherein the small U-shaped straight bar profile is relatively sleeved with the U-shaped opening of the large U-shaped straight bar profile, and the small U-shaped straight bar profile is sleeved in the large U-shaped straight bar profile.

[0013] Furthermore, the base plate is made of non-metallic composite fiber material.

[0014] The utility model also provides an oxygen cabin, comprising a cabin body and a cabin door, wherein the cabin body contains the anti-bending composite sandwich flat plate.

[0015] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0016] 1. The flat plate structure of the utility model adopts non-metallic composite fiber material, which can achieve the effect of light weight and small volume of the oxygen cabin;

[0017] 2. The through beam of the flat plate structure of the utility model adopts a double U-shaped interlocking connection form, which increases the toughness of the cabin plate and improves the bending strength;

[0018] 3. The flat plate structure of the utility model is connected with a connecting seat at the vertex of the cross rib, which increases the contact area with the inner sealing plate. The connecting seat is in close contact with the inner sealing plate, which provides a buffer for the compression deformation of the plate body, ensures reliability, and avoids abnormal noise caused by pressure deformation of the cabin.

[0022] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the scope of protection required by the present invention is not limited to the scope described in the embodiments.

[0023] Example 1

[0024] Combination Figure 1 and Figure 2 As shown, the utility model provides a bending-resistant composite sandwich flat plate, which includes a base plate 1 and an inner sealing plate 2. The surface of the base plate 1 is provided with a plurality of reinforcing rib structures, the inner sealing plate 2 is laid on the reinforcing ribs, and a through beam 4 is also provided between the base plate 1 and the inner sealing plate 2. The through beam 4 penetrates the closed space between the base plate 1 and the inner sealing plate 2.

[0025] Specifically, the base plate 1 adopts a non-metallic composite fiber material, which reduces the weight by at least 50% compared with the metal structure. The reinforcing ribs provided on the base plate 1 are cross ribs, triangular cross ribs or multi-sided cross ribs. The above-mentioned cross ribs have vertices, and one end of the connecting seat 3 is provided with a slot matching the cross ribs, and the other end is a plane. The connecting seat 3 is plugged into the vertex of the cross ribs through the slot. The connecting seat 3 is in close contact with the inner sealing plate 2 through the plane at the other end. The plane increases the contact area between the cross ribs of the base plate 1 and the inner sealing plate 2, thereby increasing the stability of the composite flat plate. Among them, the connection method between the connecting seat 3 and the inner sealing plate 2 can be a bolt connection method or a bonding method.

[0026] In this embodiment, the inner sealing plate 2 is connected to the base plate 1 through the connecting seat 3 to form a closed space. A through beam 4 is inserted in the empty space of each cross rib. Among them, the through beam 4 is a straight bar profile, and the straight bar profile is a solid column straight bar, and the solid column straight bar includes a straight bar profile with a cross section of a square, a rectangle or other polygons. In order to reduce the weight of the cabin, the through beam 4 can also be set as a hollow profile, that is, a straight bar profile with a U-shaped or square cross section. When the cross section is U-shaped, the bottom of the U-shaped is a plane to increase the contact area between the bottom of the U-shaped profile and the base plate and the inner sealing plate. In order to further ensure the anti-bending performance of the flat plate, two types of straight bar profiles with a U-shaped cross section are set: a large U-shaped straight bar profile and a small U-shaped straight bar profile. The small U-shaped straight bar profile is relatively sleeved with the U-shaped opening of the large U-shaped straight bar profile, and the small U-shaped straight bar profile is sleeved in the large U-shaped straight bar profile. Therefore, the anti-bending performance can be effectively increased.

[0027] The utility model also provides an oxygen cabin, including a cabin body and a cabin door, wherein the cabin body contains the anti-bending composite sandwich flat plate. When the anti-bending composite sandwich flat plate is applied to the cabin body, the side with the base plate 1 is applied to the outside of the cabin body, and the side with the inner sealing plate 2 is applied to the inside of the cabin body.

[0028] In summary, the above-mentioned implementation modes are not limitative implementation modes of the present invention, and any modification or equivalent deformation made by technicians in this field on the basis of the essential content of the present invention is within the technical scope of the present invention.
