[0015] Preferably, the right end of the rotating rod passes through the right side of one of the side plates, and a special-shaped groove is provided on the right side of the rotating rod.

[0016] Working principle: When assembling the wall of the prefabricated building, first unfold the stored wall, pull the main end base at the top, cooperate with the traction rope to drive the wall panel to unfold initially, and slide the secondary end base to retract so that the two ends of the wall can fit into the space of the erection frame, then place the bottom end of the wall into the erection frame, unfold the telescopic rod, and lengthen the telescopic rod so that the rod body of the telescopic rod is downward as the force-applying part, and use the rod body of the telescopic rod as the force-applying point to support the main end base of the upper part, so as to support the upper part of the folded and stored wall, and after plugging it into the erection frame at the top, plug the plug connector at the bottom of the telescopic rod into the plug sleeve for support. At this time, the deflated support airbag is stretched and unfolded, and the wall panel and the traction rope are in a loose state. After the initial support is completed, the rotating handle used as the rotation force is connected to the special-shaped groove on the right side of the rotating rod, and then the rotating handle is used as the force-applying point to rotate the rotating rod. The rotating rotating rod will transmit gear two through the gear one connected to it. When gear two rotates, it will drive the following structures to work in sequence: Gear 2 synchronously drives the abutment disk connected to it to rotate, so that the engaged abutment ring rotates on the connecting ring, and drives the driving shaft connected to it to rotate, and then the driving shaft drives the winding roller to rotate, and the traction rope is wound up. The rope body is pulled and displaced, and then the rope body drives the pulling head to abut against the cavity inside the wall panel, so that the wall panel is subjected to force, so that the multiple wall panels that have just been unfolded are neatly arranged together under the influence of the stretched traction rope. After the winding roller winds up the traction rope for a certain length, the traction rope will be tightened to arrange the wall panels neatly. At this time, there is no need to wind up the traction rope. The rope body of the traction rope will drive the pulling head to abut against the other end of the lever. At this time, the lever will be subjected to force, driving the rotating shaft to rotate. , and then the rotating shaft pulls the connecting rod at the other end to move, so that the abutment head connected to the connecting rod sinks into the shell, and drives the traction spring piece connected to it to move and abut on the collar. The collar acts as a lever fulcrum, so that the part of the traction spring piece connected to the connecting ring drives the connecting ring to move in the direction of the abutment head, and compresses the spring to displace the abutment ring connected to the connecting ring and disengage from the abutment disk, so that the driving shaft connected to the abutment ring no longer rotates. When the screw rod is subjected to the rotation transmitted by the rotating shaft through the sprocket chain, the screw rod displaces the transmission locking frame, and the teeth on the two components bite each other, which will hinder the rotation of the winding roller, and thus the traction rope on the winding roller cannot be further extended; The two meshing bevel gears drive the runner to rotate, so that the eccentric wheel push structure composed of the runner and the connecting rod pushes and pulls the piston to fill the air pipe, and then the air enters the deflated support airbag to expand it. After expansion, the support airbag will support the wall panel to support the wall panel to form a wall. Repeat the above steps to fill the wall with the erection frame to complete the wall assembly of the prefabricated building.

[0017] When it is necessary to dismantle and move the prefabricated building, for the wall, the rope located at the opening of the lever can be pulled to make the rope detach from the opening, and the cooperative pulling head no longer abuts the lever, causing the lever to lose force support and become loose. Then the screw is twisted to make the screw drive locking frame so that the fixed teeth are disengaged from the teeth of the winding roller so that the winding roller can rotate again, thereby loosening the traction rope, opening the deflation valve of the support airbag, releasing the air inside the support airbag, canceling the support for the wall panel, loosening the overall structure, and arranging the structure back in place. Finally, the plug connector is separated from the plug sleeve to release the fixation of the telescopic rod, and the top main end base is slowly lowered to organize the structure including the wall panel so that it can be completely stored.

[0018] The present invention provides a detachable wall of an assembled building, which has the following beneficial effects: 1. The present invention can be folded and stored in an unassembled state, and the volume is significantly reduced, and the occupied space is greatly reduced. This design makes the wall more convenient during transportation and storage, improves transportation efficiency, and reduces transportation and storage costs. It is particularly suitable for the modular construction needs of prefabricated buildings.

[0019] 2. The present invention realizes the rapid assembly of the wall. The wall panels that make up the wall surface can be quickly arranged and can remain firm and stable. When disassembling, the wall panels can be quickly loosened and disassembled and put away by folding and storing, which greatly improves the efficiency of assembly and disassembly and saves construction time and labor costs.

A deflation valve for deflation is provided on one side of the support airbag 7, and the inner liner of the support airbag 7 is an airbag structure that can be inflated and deflated normally, and the outer part is woven with wear-resistant nylon to protect the internal airbag structure.

[0024] Please see attached Figure 8 In this state, the wall is stored and transported, which reduces the volume and height of the wall as a whole, making it easier to transport the wall before and after assembly, so that the wall, a large-volume and large-area house component, can occupy a smaller space, increasing the number of walls to be transported or reserving the remaining free space for transporting other prefabricated house components. Figure 5 and attached Figure 6 It can be seen that vertical grooves are provided on the outer sides of the wall panel 4 and the secondary end base 3, and vertical protrusions corresponding to the vertical grooves are provided on the inner sides. When the wall panel 4 is folded and stored, it can be positioned and arranged along the vertical grooves and the vertical protrusions so that it is arranged neatly. When multiple wall panels 4 are stacked and arranged, the secondary end base 3 will be pulled to expand the gap between the secondary end base 3 and the main end base 2 so that it can just accommodate multiple stored wall panels 4.

[0025] Please see attached Figure 3 , Attachment Figure 5 and attached Figure 6The traction rope is mainly composed of a rope body 5 and a pulling head 6. The two rope bodies 5 fixedly connected to the top side of the bottom wall panel 4 are both made of high-strength nylon rope and steel wire mixed together, and both have reliable strength to extend the service life and prevent breakage. The top of the rope body 5 sequentially penetrates the interior of multiple wall panels 4 and the inner wall of the top auxiliary end base 3. The top of the rope body 5 is wound around the outer wall of the winding roller 16. Please refer to the attached Figure 7 and attached Fig.15 The outer wall of the wall panel 4 is fixedly connected with a plurality of pull heads 6, one of which is in contact with the other end opening of the lever 18, and the remaining pull heads 6 are in contact with the inside of the wall panel 4. Please refer to the attached Figure 3 , Attachment Figure 4 and attached Fig.11 The bottom side of the top main end base 2 is fixedly connected with a pulley, and the left and right ends of the top side of the bottom main end base 2 are fixedly connected with two pulley traction frames 31, and the two pulley traction frames 31 are respectively located at the front and rear sides of the winding roller 16, and the rope body 5 rolls with the pulley and the pulley traction frame 31 in turn to change the direction; Specifically, the design of the pulley and the pulley traction frame 31 helps the traction rope to confirm the direction after the wall panel 4 is tightened, so as to ensure that the traction head 6 triggers the lever 18 and the winding roller 16 is normally wound. When the winding roller 16 rotates to wind the traction rope, the rope body 5 is pulled and displaced, and then the rope body 5 drives the traction head 6 to abut against the cavity inside the wall panel 4, so that the wall panel 4 is stressed, so that the multiple wall panels 4 that have just been unfolded are neatly arranged together under the influence of the stretched traction rope, and the traction head 6 located at the lever 18 position applies force to the lever 18, so that the lever 18 rotates at a certain angle.

[0026] Please see attached Fig.11 , Attachment Fig.12 and attached Fig.15 The clutch shaft includes a housing 11 located on one side of the gear 2 10. The bottom side of the housing 11 is fixedly connected to the top side of the bottom main end base 2. The middle end of the housing 11 is connected to an abutment ring 13 through a separation component. One side of the abutment ring 13 is fixedly connected to a driving shaft 15. The driving shaft 15 is plugged into one side of the winding roller 16 through a spline shaft. The spline shaft can keep the winding roller 16 unaffected when the driving shaft 15 is displaced, and can maintain the function of transmitting rotation. The other side of the abutment ring 13 is engaged with an abutment disk 12. The abutment ring 13 and the abutment disk 12 are both provided with grooves to increase friction, so that when they are engaged with each other, they can synchronously drive the abutment ring 13 to rotate when the abutment disk 12 rotates. The abutment disk 12 is fixedly connected to one side of the gear 2 10. Please refer to the attached Fig.13 -Attached Fig.15The inner wall of the abutment head 33 slidably connected to the middle end of the housing 11 is rotatably connected to the driving shaft 15. The side of the abutment head 33 close to the abutment ring 13 is connected to the connecting ring 32 through the traction spring 14. The traction spring 14 is inserted into the ring fixed on the inner wall of the housing 11. The abutment ring 13 is rotatably connected to the connecting ring 32. The connecting ring 32 is connected to the housing 11 through a spring. The spring is used to assist the connecting ring 32 in resetting when it needs to be reset after it is displaced. Specifically, when the rotating rod 8 rotates, driving the gear 1 9 and the transmission gear 2 10 to rotate, the gear 2 10 synchronously drives the abutment disk 12 connected thereto to rotate, so that the engaged abutment ring 13 rotates on the connecting ring 32, and drives the driving shaft 15 connected thereto to rotate, and then the driving shaft 15 drives the winding roller 16 to rotate.

[0027] Please see attached Fig.13 -Attached Fig.15 , two rotating shafts 17 are located on the left and right sides of the housing 11, the bottom side of the rotating shaft 17 is rotatably connected to the top side of the bottom main end base 2, the top of the rotating shaft 17 is fixedly connected to a lever 18, the two levers 18 are mirror-symmetrical, the outer wall of one end of the connecting ring 32 close to the winding roller 16 is fixedly connected to two connecting rods 19, one end of the lever 18 is slidably connected to the connecting rod 19, and the other end opening of the lever 18 is sleeved on the rope body 5; Specifically, after the winding roller 16 winds up the traction rope to a certain length, the traction rope will be tightened to arrange the wall panels 4 neatly. At this time, there is no need to wind up the traction rope. The rope body 5 of the traction rope will drive the traction head 6 to abut the other end of the lever 18. At this time, the lever 18 will be subjected to force to drive the rotating shaft 17 to rotate, and then the rotating shaft 17 drives the connecting rod 19 at the other end to move, so that the abutting head 33 connected to the connecting rod 19 is sunk into the shell 11, and drives the traction spring piece 14 connected thereto to move and abut on the ring. The ring acts as a lever fulcrum, so that the part of the traction spring piece 14 connected to the connecting ring 32 drives the connecting ring 32 to move in the direction of the abutting head 33, and compresses the spring, so that the abutting ring 13 connected to the connecting ring 32 is displaced and disengaged from the abutting disk 12, so that the driving shaft 15 connected to the abutting ring 13 no longer rotates.

[0028] Please see attached Fig.15 and attached Fig.16The screw 20 and the slide bar 21 on the other side of the winding roller 16, the bottom end of the screw 20 is rotatably connected to the top side of the bottom main end base 2, the bottom end of the slide bar 21 is fixedly connected to the top side of the bottom main end base 2, the screw 20 is connected to one of the rotating shafts 17 through two sprockets driven by a chain, a locking frame 22 is provided on the bottom side of the winding roller 16, the top side of the locking frame 22 and the outer wall of the other side of the winding roller 16 are fixedly connected with teeth, one end of the locking frame 22 is threadedly connected to the screw 20, and the other end of the locking frame 22 is slidably connected to the slide bar 21 to prevent the locking frame 22 from being screwed. The transmission of rod 20 rotates, thereby stabilizing the normal movement of locking frame 22. When screw rod 20 is subjected to the rotation transmitted by rotating shaft 17 through sprocket chain, screw rod 20 will drive locking frame 22 to move, and the teeth on the two components will bite into each other, which will hinder the rotation of winding roller 16, thereby making it impossible for the traction rope on winding roller 16 to continue to lengthen. Among them, the specifications of the two sprockets are different. The size of the sprocket on the rotating shaft 17 is larger than the size of the sprocket on the screw rod 20, thereby expanding the rotation amplitude of the rotating shaft 17 on the screw rod 20, so that it can drive the locking frame 22 for a longer distance.

[0029] Please see attached Fig.17 -Attached Fig.19 The air pump includes a cylinder 24 fixedly connected to the input end of the air pipe 23, a piston 25 is slidably connected to the inner wall of the cylinder 24, a runner 26 is slidably connected to the outer wall of the cylinder 24 through a fixed frame, one side of the runner 26 is connected to the other side of the gear 2 10 through two meshing bevel gears, and a connecting rod 27 is provided on the other side of the runner 26, one end of the connecting rod 27 is rotatably connected to the outer periphery of the other side of the runner 26, and the other end of the connecting rod 27 is rotatably connected to the side of the piston 25 close to the runner 26, and the inner wall of the input port and the inner wall of the output port of the cylinder 24 are fixedly connected with a one-way valve diaphragm to prevent the gas of the support airbag 7 connected to the air pipe 23 from flowing back during air intake, resulting in gas leakage, so that the gas is unidirectionally perfused during inflation; Specifically, a rubber layer is provided at the end of the piston 25, which fits with the inner wall of the cylinder 24 to ensure sealing, so that when the piston 25 is pulled, a negative pressure is stably generated inside the cylinder 24 to perform external air extraction. When the gear 2 10 is in rotation, the two meshing bevel gears drive the rotating wheel 26 to rotate, so that the eccentric wheel push structure composed of the rotating wheel 26 and the connecting rod 27 pushes and pulls the piston 25 to inject air into the air pipe 23, and then the air enters the deflated support airbag 7 to expand it. After the expansion, the support airbag 7 will support the wallboard 4, making the wallboard 4 more solid.

[0030] Please see attached Figure 2 , Attachment Figure 3 and attached Figure 8The left and right sides of the top main end base 2 are connected with telescopic rods 30 through hinges. The telescopic rod 30 is provided with an extension locking structure. The bottom side of the telescopic rod 30 is fixedly connected with a plug connector 28, and the top side of the side plate is fixedly connected with a plug sleeve 29.
