Description

Technical Field

[0001] The utility model relates to the technical field of micro-pressure oxygen chamber equipment, in particular to a spliced ​​sealed chamber. Background Art

[0002] As a health-care consumer product, micro-pressure oxygen chambers are increasingly entering people's lives. Existing oxygen chambers are mainly splicing installation type, which has high requirements for the stability of the cabin. The existing splicing cabin plate connection is mainly overlapped and butt-jointed. The overlap connection method is that the two plates overlap at the contact position, and the plates are fixed by bolts perpendicular to the plates. In this way, when the cabin is under pressure, there is a relative displacement of the overlap surface, and the cabin often has obvious noise, affecting the user experience. The butt connection method is that the two plates are butt-jointed laterally, and the plates are fixed by connecting bolts parallel to the plates. In this way, when the cabin is under pressure, there is no relative displacement of the contact surface, and the cabin noise is small, but this type of structural bolts are subjected to greater force, and the reliability of the bolt connection is required to be higher. At present, most of the butt connection methods on the market often use sealants to seal the plate joints after the cabin is assembled, but this method has cumbersome construction steps and is not conducive to subsequent disassembly and assembly.

[0003] In view of the above reasons, how to eliminate abnormal noise in the cabin and provide a micro-pressure oxygen chamber that is easy to disassemble and assemble and has a cabin connection that does not require gluing and sealing is a problem that needs to be solved at present.

The planar connector 1 has a cabin body plate connecting surface 12. The planar connector 1 is sealed and connected to the cabin body plate through the cabin body plate connecting surface 12.

[0021] Preferably, the butt joint surface 11 is further provided with a positioning groove 6 extending along the length direction of the butt joint surface 11, and two positioning grooves 6 of two adjacent butt joint surfaces are correspondingly provided, and a positioning steel bar 4 is placed in the positioning groove 6. Here, the cross section of the positioning groove 6 is square, trapezoidal, triangular or circular, and the shape of the positioning steel bar 4 matches the strip groove 6, which is not limited by the present invention.

[0022] In addition, a sealing groove 5 extending along the length direction of the butt joint surface is provided on the butt joint surface, and a sealing rubber strip 3 is placed in the sealing groove 5. The cross section of the sealing rubber strip 3 is circular or semicircular, and the thickness of the sealing rubber strip 3 is greater than the depth of the sealing groove 5. When the planar connector 11 and the planar connector 12 are butt-jointed and fixed, the sealing rubber strip of the planar connector 11 and the sealing rubber strip of the planar connector 12 are squeezed against each other under the action of external force to achieve interference fit and achieve the best airtight effect.

[0023] Here, the plane connector 1 is a frame-shaped structure, and two adjacent sides of the frame are provided with two mutually perpendicular sealing grooves 5, and a right-angle sealing strip 313 is provided at the intersection of the two mutually perpendicular sealing grooves 5, and the two ends of the right-angle sealing strip 313 are respectively tightly connected with the ends of the sealing strip a311 and the sealing strip b312 in the two mutually perpendicular sealing grooves 5.
