[0027] The utility model embodiment provides a novel inflatable cabinet casing and an inflatable cabinet, the novel inflatable cabinet casing comprises a first casing 10 and a second casing 20;

[0028] The side wall of the first sleeve 10 is provided with a first threaded end 13;

[0029] A second threaded end 23 is provided on a side wall of one end of the second sleeve 20;

[0030] The first threaded end 13 is threadedly connected to the second threaded end 23;

[0031] A pressing plate 30 is disposed on the outer wall of the first sleeve 10 ; a fastener 40 is disposed on the pressing plate 30 ; the fastener 40 is used to pass through the pressing plate 30 and connect with the side wall 50 of the inflatable cabinet.

[0032] When implementing it, Figure 1-Figure 4As shown, the novel inflatable cabinet casing includes a first casing 10 and a second casing 20; the first casing 10 includes a first insulator 11 and a first conductor 12; the second casing 20 includes a second insulator 21 and a second conductor 22;

[0033] One end of the first sleeve 10 passes through the second threaded end 23 and enters the second sleeve 20 to make the first conductor 12 contact the second conductor 22, and the contact portion between the first conductor 12 and the second conductor 22 is provided with an insulating filling sleeve 28; the first insulator 11 has a first threaded end 13 on its side wall circumference, and the first threaded end 13 is an internal threaded end or an external threaded end; the second insulator 21 has a second threaded end 23 on its outer wall at one end, and the second threaded end 23 is an external threaded end or an internal threaded end; the first threaded end 13 is threadedly connected with the second threaded end 23; the first insulator 11 has a pressure plate 30 formed separately or integrally; a plurality of fasteners 40 are pierced on the pressure plate 30, and the fasteners 40 are bolts; the fasteners 40 pass through the pressure plate 30 and are threadedly connected with the through holes at the corresponding positions of the side wall 50 of the inflatable cabinet.

[0034] During installation, the first sleeve 10 is passed through the sleeve mounting hole on the side wall 50 of the gas cabinet. The diameter of the first sleeve 10 at this position is smaller than the diameter of the sleeve mounting hole. Then, the first sleeve 10 is fixed to one side of the side wall 50 of the gas cabinet by means of the pressure plate 30 and the fastener 40. Then, the second threaded end 23 of the second sleeve 20 is passed through the gap between the outer wall of the first sleeve 10 and the sleeve mounting hole, and the second threaded end 23 is screwed into the first threaded end 13 to be threadedly connected thereto. The assembly is convenient. Compared with the solution of using several groups of bolts for connection and fixing at this position, the installation and disassembly time of the second sleeve 20 can be greatly shortened, thereby improving the installation and disassembly efficiency of the sleeve.

[0035] The new inflatable cabinet sleeve provided by the embodiment of the utility model has a structure in which the first threaded end of the first sleeve is threadedly connected to the second threaded end of the second sleeve. Compared with the existing structure, the disassembly and installation steps are very simple and convenient, thereby improving the installation and disassembly efficiency of the sleeve.

[0036] Furthermore, the first threaded end 13 is separated from the first sleeve 10 ; the first threaded end 13 is limited between the pressing plate 30 and the side wall 50 of the inflatable cabinet.

[0051] When implementing it, Figure 2 As shown, the pressure plate 30 is a triangle; fasteners 40 are provided at the three corner directions of the pressure plate 30, and the triangle has stability. In this embodiment, three fasteners 40 are provided compared to the existing four or more fasteners. Under the premise of ensuring the stable strength of the connection, the use of fasteners is reduced, thereby further shortening the installation and removal time of the sleeve, and further improving the installation and removal efficiency of the sleeve.

[0052] Furthermore, a second limiting protrusion 24 is provided on the side wall of the second sleeve 20 ; a groove 241 is provided on the side of the second limiting protrusion 24 facing the side wall 50 of the inflatable cabinet; and a sealing ring 242 is provided in the groove 241 .
