Description

Technical Field

[0001] The utility model relates to the technical field of folding houses, in particular to a connection structure of a double-wing folding house. Background Art

[0002] With the development of society, the demand for folding houses is increasing. At present, most of the houses used for temporary residence on the market are prefabricated houses. Prefabricated houses have their inherent advantages, such as low cost and regular shape after disassembly and assembly, but the ground pillars need to be buried before construction. The prefabricated houses built under this condition cannot be moved. If you want to dismantle them after they are successfully built, it will take a lot of manpower. In contrast, the advantages of folding houses stand out. They can also cope with many emergencies and build many temporary residences for people to use, such as temporary temperature monitoring rooms, nucleic acid testing rooms, outdoor picnic huts, temporary camps for soldiers, field hospitals, etc. in communities, schools and other public places. Resettlement points can be provided in time when disasters such as earthquakes and mudslides occur, and the emotions of the victims can be stabilized.

[0003] However, the existing double-wing folding houses mostly use bolts to connect and fix the side panels during use, and the efficiency of installation and disassembly is low. For example, the utility model patent with Chinese patent application number CN202221638444.4 discloses a folding house, which includes a first plate body, a second plate body and a third plate body. The first plate body is the bottom plate and the top plate of the folding house, the second plate body is the front plate and the back plate of the folding house, and the third plate body is the left wall plate and the right wall plate of the folding house, which together constitute a rectangular house structure. During the construction of the main body of the folding house in the above-mentioned prior art, multiple positioning bolts are needed to fix the side panels, and the installation efficiency is low. It is also inconvenient to disassemble the folding house afterwards. Utility Model Content

The second positioning port 14 is opened on the positioning disk 13, and the second positioning port 14 is connected to the first positioning port 12. The first gear 15 is rotatably set in the second positioning port 14. The second positioning port 14 is located on both sides of the first gear 15 and the second gears 16 are rotatably set respectively. The first gear 15 is meshed with the second gear 16, and a positioning block 17 is fixedly set on the side wall of each second gear 16. The driving mechanism is set on the connecting disk 10, which is used to control the first gear 15 to rotate.

[0060] Specifically, after the connecting column 9 is inserted into the connecting port 7 through the installation port, the operator can control the first gear 15 to rotate through the driving mechanism, and at the same time, the second gear 16 is driven to rotate through the engagement of the first gear 15 and the second gear 16, so that the positioning block 17 moves around the second gear 16, so that the positioning block 17 can be inserted into the connecting groove 8 through the first positioning port 12 and the second positioning port 14 and contact the side wall of the connecting groove 8 close to the installation port.

Therefore, when the thickness of the plate changes and causes the connecting column 9 to become loose, the positioning block 17 can be driven to move by the movement of the positioning plate 13, so that the positioning block 17 can contact the side wall of the connecting groove 8, thereby avoiding the problem of loose connection caused by plate processing errors.

[0065] In this embodiment, when in use, after completing the position adjustment between the side panels of the folding room body 1, the operator extends the connecting column 9 through the installation opening into each connecting opening 7, and then the operator rotates the hand wheel 18. The rotation of the hand wheel 18 can drive the driving column 19 to rotate, and at the same time, the first gear 15 is driven to rotate through the sliding cooperation relationship between the driving column 19 and the first gear 15, and the second gear 16 is driven to rotate through the meshing of the first gear 15 and the second gear 16, so that the positioning block 17 moves around the second gear 16, so that the positioning block 17 can extend into the connecting groove 8 through the first positioning opening 12 and the second positioning opening 14 and contact the side wall of the connecting groove 8 close to the installation opening. In this state, the connection column 9 can be installed by the cooperation between the connection disk 10 and the mounting block, thereby realizing the connection and fixation between the side plates. When the connection between the side plates becomes loose, the operator rotates the drive ring 22. The rotation of the drive ring 22 can drive the threaded rod 20 to rotate synchronously through the engagement of the first annular rack and the third gear 21, and then the threaded cooperation between the threaded rod 20 and the threaded hole drives the positioning disk 13 to adjust the position. When the thickness of the plate changes and causes the connection column 9 to become loose, the positioning block 17 can be driven to move by the movement of the positioning disk 13, so that the positioning block 17 contacts the side wall of the connecting groove 8, thereby avoiding the problem of loose connection caused by plate processing errors.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
