DETAILED DESCRIPTION

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] As attached Figure 1-2A quick-release internal support structure of a mobile house is shown, comprising a first positioning cylinder 1 and a second positioning cylinder 2. A first positioning block 5 is provided on one side of the inner surface of the first positioning cylinder 1. The first positioning cylinder 1 and the first positioning block 5 are an integrated structure. A first threaded support rod 3 is inserted into the inner surface of the first positioning cylinder 1. A first positioning groove 6 is provided at the upper end of the outer surface of the first threaded support rod 3. A second threaded support rod 4 is inserted into the inner surface of the second positioning cylinder 2. A second positioning block 7 is fixedly connected to the lower side of the outer surface of the second threaded support rod 4. The second threaded support rod 4 and the second positioning block 7 are an integrated structure. A second positioning groove 8 is provided on one side of the inner wall of the second positioning cylinder 2.

[0021] A nut 10 is installed at the lower part of the outer surface of the first threaded support rod 3, and the lower part of the outer surface of the first threaded support rod 3 is located below the nut 10 and is sleeved with a support tube 9. The lower end of the first threaded support rod 3 is located in the support tube 9 and is provided with a limit block 11. The first threaded support rod 3 and the limit block 11 are an integrated structure, and a gasket 14 is arranged between the nut 10 and the support tube 9. The gasket 14 is sleeved on the support tube 9, and the gasket 14 is a rubber sheet. The friction between the nut 10 and the support tube 9 is increased by the gasket 14, so that the nut 10 is not easy to loosen, thereby improving the use effect of the equipment. When the first threaded support rod 3 is located in the support tube 9 and its upper end is not inserted in the first positioning tube 1, the upper end of the first threaded support rod 3 is exposed on the outside of the upper end of the support tube 9, which is convenient for assembling and using the first threaded support rod 3.

[0022] The lower part of the inner surface of the support tube 9 is provided with a thread, and the lower part of the support tube 9 is mounted on the upper end of the second threaded support rod 4 .

[0023] A mounting plate 12 is disposed at the opposite end of the first positioning tube 1 and the second positioning tube 2 . The first positioning tube 1 , the second positioning tube 2 and the mounting plate 12 are an integrated structure, and a plurality of mounting holes 13 are formed on the mounting plate 12 .

[0024] Working principle of the utility model: when using the inner support structure, first assemble the first threaded support rod 3 with the support tube 9, then assemble the support tube 9 with the second threaded support rod 4, and then assemble the first positioning tube 1 with the first threaded support rod 3 through the first positioning block 5 and the first positioning groove 6, and assemble and fix the second threaded support rod 4 with the second positioning tube 2 through the second positioning block 7 and the second positioning groove 8. At this time, the entire device is fixed to the inner side of the wall panel of the mobile house through the mounting hole 13 on the mounting plate 12. After the fixing is completed, by tightening the nut 10, under the action of the limit block 11, the support tube 9 is fixed to the lower end of the first threaded support rod 3 and cannot move, thereby the inner support structure is fixed. The overall fixation makes the supporting structure have a certain supporting effect on the mobile house. When the mobile house needs to be disassembled, the nut 10 is loosened to make the support tube 9 movable. At this time, the support tube 9 is rotated to disengage it from the second threaded support rod 4, and then the second threaded support rod 4 and the first threaded support rod 3 are taken out from the second positioning tube 2 and the first positioning tube 1 respectively, so that the internal supporting structure can be quickly disassembled, and the first positioning tube 1 and the second positioning tube 2 are left on the inner side of the wall panel of the mobile house, which provides a certain convenience for the next assembly of the mobile house. In summary, the internal supporting structure has strong stability and simple structure, and is convenient for quick disassembly and assembly, which helps to improve the efficiency of the overall assembly and disassembly of the mobile house and is convenient for use.
