Description

Technical Field

[0001] The invention relates to the technical field of spliced ​​movable board houses, and in particular to a connection structure of a spliced ​​movable board house. Background Art

[0002] A prefabricated house is a kind of house that uses light steel as the frame, movable panels as the enclosure material, and a standard module series for space combination. Generally, during the splicing process, four light steel or aluminum alloy column connectors are first installed on the base plate, and then the crossbeam is installed between the column connectors, and then the movable panels are installed. However, during the operation, especially when installing the movable panels and column connectors, the movable panels need to be supported, otherwise there will be a tilt or fall, resulting in inconvenience in installation. If light steel column connectors are used, they are heavy in themselves. When splicing the prefabricated house, the operator needs to carry, support and install them, and other operating steps. The weight will cause physical fatigue to the operator. If the operator falls to the ground due to operational errors during the transportation and support process, it is also easy to cause injury to the operator. If aluminum alloy column connectors are used, the material problem itself will cause the structural strength of the connector to be insufficient, affecting its use.

[0003] When splicing beams, they need to be positioned by manual movement and prevented from tilting or falling by hand support. However, this operation method makes it inconvenient for operators, and operating errors may cause the beams to fall, which in turn causes certain dangers. In addition, the indoor air of the spliced ​​mobile house will have poor fluidity when it is hot or rainy, resulting in a poor experience for the residents. At the same time, because its movable panels cannot be cooled due to long-term exposure to the sun, its service life will be affected. Therefore, the present application provides a connection structure of a spliced ​​mobile house to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a connection structure of a spliced ​​mobile house to solve the problem that during the operation of the existing connection structure, especially when the mobile board and the column connection piece are installed, the mobile board needs to be supported, otherwise it will tilt or fall, resulting in inconvenience in installation. For example, if a light steel column connection piece is used, it is heavy in itself. When the mobile house is spliced, the operator needs to carry, support and install the operation steps, which will cause physical fatigue to the operator due to the weight. If the operator falls to the ground due to operational errors during the carrying and supporting process, it is also easy to cause injuries to the operator. If an aluminum alloy is used, the mobile board will not fall down due to operational errors during the carrying and supporting process. The material of the column connector itself may cause the structural strength of the connector to be insufficient due to material problems, which affects its use. When splicing beams, it is necessary to manually move them to position them and use hand support to prevent them from tilting or falling. However, this operation method makes it inconvenient for operators. Operational errors may also cause the beams to fall, which in turn causes certain dangers. In addition, the indoor air of the spliced ​​mobile house will have poor fluidity when it is hot or rainy, resulting in a poor experience for the residents. At the same time, because its movable panels cannot be cooled down due to long-term exposure to the sun, its service life will be affected.

At the same time, the groove body of the cross beam 81 is clamped to the top of the movable plate, so as to perform the next step of operation.

[0046] When ventilation is performed, the screw rod can be rotated by shaking the crank handle, which will cause the nut 734 to move on the screw rod through the pulling plate 733, the wind shield plate 732 and the arc-shaped vertical plate 731 as the limiting guide, and further pull the pulling plate 733 to move, and at the same time, the wind shield plate 732 will be close to the end of the pulling plate 733, and further deform the arc-shaped vertical plate 731, and at the same time, the wind shield plate 732 will be away from the air inlet hole 71, so that the air inlet hole 71 is connected with the cavity. At the same time, when the wind shield plate 732 moves, it will pull the rotating ball sleeve to move, and the rotating ball sleeve will drive the ball to move, and at the same time, the L-shaped rod will pull the pulling rod 75 to move, and the pulling rod 75 will pull the U-shaped spring piece 76 when it moves. 3 moves, which in turn pulls the first dust shield 761 and the U-shaped spring piece 763 to rotate, and also causes the plug-in board to move in the slot, and also drives the movable baffle 771 to move, so that a gap is formed between the first dust shield 761 and the second dust shield 762. When air flows into the first L-shaped slot body 33 through the gap, the air enters through the end of the wind collecting bucket 772 with a larger hole diameter, and flows out through the end with a smaller hole diameter. The air will be accelerated, and the accelerated air will enter the cavity through the air inlet hole 71. The air will contact the wind shield 732 and further enter the air outlet hole 72, and then enter the second L-shaped slot body 43 through the air outlet hole 72, and then be diverted into the spliced ​​movable board room by the second L-shaped slot body 43.
