[0188] Figure 17The positioning lock fixing plate 11 is provided with a through cavity 11-1, the positioning lock bolt head 10-1-2 is nested in the through cavity 11-1, the through cavity 11-1 is nested in the second through hole 3-1-5, and the bolt passes through the third mounting hole 3-1-3 to fix the positioning lock fixing plate 11 on the profile.

[0189] As shown in Figure 11 , the bolt head part 4-1-1 is a disc-shaped bolt head; the bolt rod part 4-1-2 includes a cylindrical plug-in bolt rod and a fixed bolt rod, one end of the plug-in bolt rod is connected with the disc-shaped bolt head, the other end of the plug-in bolt rod is connected with the fixed bolt rod, and the positioning bolt 4-1 further includes a positioning mounting plate 4-1-3, as shown in Figure 18 , two first insertion holes 4-1-3-1 are provided on the positioning mounting plate 4-1-3. The fixed bolt rod is connected with the second frame inner support 2-3 after passing through a first insertion hole 4-1-3-1 and a second mounting hole 3-1-2 in sequence, and the bolt is connected with the second support after passing through the remaining first insertion hole 4-1-3-1 and the second mounting hole 3-1-2 in sequence.

[0190] As shown in Figure 19 , the positioning bolt container 3-4 includes a second insertion hole 3-4-1 for inserting the bolt head part 4-1-1 and a third insertion hole 3-4-2 for inserting the bolt rod part 4-1-2; the third insertion hole 3-4-2 is not allowed to pass through the bolt head part 4-1-1, the positioning bolt container 3-4 is a hollow pipe, the second insertion hole 3-4-1 is a pipe cavity of the positioning bolt container 3-4, and the third insertion hole 3-4-2 is a strip-shaped hole provided on the pipe wall of the hollow pipe and extending longitudinally along the hollow pipe, one end of the third insertion hole 3-4-2 extends to the end of the hollow pipe, the positioning bolt container 3-4 is provided with a fourth insertion hole 3-4-3, and the bolt is connected with the second support after passing through the second mounting hole 3-1-2 on the left profile 3 and the fourth insertion hole 3-4-3 in sequence.

[0191] The installation process of the left and right adjacent card building modules of the present application is as follows: firstly, a card building module and another card building module are staggered at a certain distance in the direction that the positioning bolt 4-1 is inserted into the positioning bolt container 3-4, then one side of a card building module is abutted with one side of another card building module, and then the positioning bolt 4-1 is inserted into the positioning bolt container 3-4, the bolt head part 4-1-1 is inserted into the first insertion hole 4-1-3-1, and the bolt rod part 4-1-2 is inserted into the second insertion hole 3-4-1, and the connection of the positioning bolt container 3-4 and the positioning bolt 4-1 is as shown in Figure 20 . At this time, the sectional view of the connection of the two modules is as shown in Figure 21 .

[0192] Because the opening size of the second insertion hole 3-4-1 does not allow the bolt head 4-1-1 to pass through, and the bolt head 4-1-1 is exactly against the inner wall of the positioning receiving bolt 3-4, the bolt rod 4-1-2 can be inserted into the second insertion hole 3-4-1. That is, the bolt rod is not allowed to move along the width direction of the second insertion hole 3-4-1, so that the two building module components are accurately installed and positioned in the width direction of the second insertion hole 3-4-1 and the length direction of the bolt rod 4-1-2. Then, the pull rod 10-1-4 of the positioning lock 10 is pulled out from the first rod slot 10-2-1 and rotated a certain angle around the tube axis of the bolt receiving hollow tube 10-2, so that the pull rod 10-1-4 is engaged in the second rod slot 10-2-2. At this time, the positioning bolt head 10-1-2 is inserted into the second through hole 3-1-5. Since the size of the lock hole allows the positioning bolt head 10-1-2 to be inserted but does not allow the positioning bolt head 10-1-2 to move within the second through hole 3-1-5, accurate installation and positioning of the two building module components in the insertion direction of the positioning bolt 4-1 into the positioning receiving bolt 3-4 can be achieved. Finally, accurate installation and positioning of the two building module components in all directions are achieved, reducing connection and installation errors. Moreover, this connection and installation process actually only requires two steps: the insertion of the positioning bolt 4-1 into the positioning receiving bolt 3-4 and the insertion of the positioning lock 10 into the second through hole 3-1-5. The installation process is very simple and quick. The disassembly process of the two fabric-covered building modules is the reverse of the installation process. First, pull the rotating rod 10-1-4 out of the second rod slot 10-2-2 and rotate it around the tube axis of the locking bolt accommodating the hollow tube 10-2 by a certain angle. Under the action of the restoring force of the spring 10-3, the rotating rod 10-1-4 is inserted into the second rod slot 10-2-2. At this time, the positioning locking bolt head 10-1-2 is dislodged from the locking hole. Then, the two fabric-covered building modules are staggered along the direction in which the positioning bolt 4-1 is inserted into the positioning receiving bolt 3-4, so that the positioning bolt 4-1 is dislodged from the positioning receiving bolt 3-4, thus completing the separation of the two fabric-covered building modules.

[0193] When the upper and lower fabric assembly modules are connected, the upper profile 1 of the lower fabric assembly module with the positioning and fixing pin 1-1 is directly opposite the lower profile 2 of the upper assembly module with the circular hollow tube. At this time, the spherical column head 1-1-1 of the positioning and fixing pin 1-1 is inserted successively into the first through hole 3-1-4, the first insertion hole 5-1 of the frame corner connector 5 and the first frame inner support 2-2 on the profile of the upper assembly module, and finally enters the first hole 2-1-1 on the circular hollow tube. A part of the small diameter column 1-1-2-1 also enters the first hole 2-1-1, while the large diameter column 1-1-2-2 enters the first insertion hole 5-1. The connection between the positioning and fixing pin 1-1 and the positioning and fixing pin locking piece 2-1 is as follows: Figure 22shown. At this time, a rotating special tool (not shown) is inserted into the second through hole 3-1-5 of the upper clamping building module with the jaw part 2-1-3, the rotating special tool is engaged with the jaw part 2-1-3, and the rotating special tool is rotated by 90 degrees. Then, the circular hollow tube is also rotated by 90 degrees around its tube axis. At this time, the small-diameter columnar rod 1-1-2-1 enters the second hole 2-1-2, the spherical head part 1-1-1 is clamped in the lumen of the circular hollow tube and cannot be taken out, and the head part friction limiting part 2-2-4 is in frictional contact with the spherical head part 1-1-1 and is tightly contacted, preventing the circular hollow tube from rotating in the opposite direction and causing the head part 1-1-1 to be taken out of the circular hollow tube. Thus, the upper connection and left connection of the building module are completed, as shown in Figure 23

[0194] In a preferred embodiment, as shown in Figure 24 After the clamping building module is installed, a cloth cover can be arranged on at least one side of the front and rear of the frame, covering the lamp panel 8 or the lining plate 7 on the decorative plane 6 and being clamped in the first groove 3-1 and the second groove 3-2, so that the whole is more beautiful.

[0195] The beneficial effects of the present application are:

[0196] 1) The frame, the positioning fixing pin 1-1 and the positioning fixing pin lock 2-1, the positioning bolt 4-1, the positioning container bolt 3-4, and the positioning lock 10 of the building module component are preferably made of metal, and the decorative part is made of plastic. All parts can be recycled, and the waste of forest resources is avoided, and the environmental protection is good.

[0197] 2) Since the connection between the upper and lower building module components only needs to insert the positioning fixing pin 1-1 of one building module component into the positioning fixing pin lock 2-1 of another building module component and move the positioning fixing pin lock 2-1, preferably rotating these two steps, the connection between the left and right building module components only needs one installation step of inserting the positioning bolt 4-1 of one building module component into the positioning container bolt 3-4 of another building module component. Compared with the traditional bolt connection and welding, the connection and disassembly between the building module components are very convenient and fast, and the manpower, material resources and financial resources are greatly saved.

[0198] 3) The building module components of the present application are all standard components, the customization cycle is greatly shortened, and the economic cost is greatly reduced.

[0199] 4) The accurate installation and positioning between the two upper and lower and left and right building module components can be realized, and the error during installation and connection is greatly reduced.

[0200] 5) When the two building module components are combined together, the positioning fixing pin 1-1, the positioning bolt 4-1, the positioning container bolt 3-4, and the positioning lock 10 are hidden in the profile of the frame of the building module component, and the overall appearance of the building module component is good.​

[0201] 6) The lamp plate 8 and the lining plate 7 are installed in the decorative plane 6 formed by the frame module, which can effectively reduce the damage caused by bumps. When the Kabu building module in the application is used again, only the Kabu installed in the second groove 3-2 needs to be replaced, which is convenient to use.
