[0034] like Figures 1 to 4As shown, this embodiment proposes a prefabricated component connection device, including a male connector 100 and a female connector 200. The male connector 100 includes a male sleeve 110 and a bolt 120. The male sleeve 110 has a receiving cavity 111. The bolt 120 includes a head 121 and a connecting rod 122. The head 121 is located in the receiving cavity 111, and the connecting rod 122 extends out of the receiving cavity 111. The female connector 200 includes a female sleeve 210 and a nut 220. The female sleeve 210 has a mounting cavity 211, and the nut 220 is located in the mounting cavity 211. When the male connector 100 and the female connector 200 are assembled and connected, the connecting rod 122 of the bolt 120 is inserted into the mounting cavity 211 of the female sleeve 210 and threadedly connected to the nut 220. The bolt 120 is provided with adjusting teeth 300, which are used to adjust the rotational displacement of the nut 220 on the bolt 120. The male sleeve 110 is provided with adjusting holes 310 corresponding to the adjusting teeth 300, so that the adjusting device can pass through the adjusting holes 310 to adjust the adjusting teeth 300. The receiving cavity 111 is provided with an elastic element 400 for applying axial thrust to the bolt 120. The elastic element 400 includes a first end and a second end. The first end of the elastic element 400 abuts against the receiving cavity 111, and the second end abuts against the head 121 of the bolt 120. A clearance space is formed between the second end of the elastic element 400 and the adjusting teeth 300 for the insertion of the adjusting device. When the adjusting device adjusts the adjusting teeth 300, the elastic element 400 avoids the adjusting device. In this embodiment, the first end of the elastic element 400 is the upper end as shown in the figure, and the second end is the lower end.

[0035] In this embodiment, by providing a clearance space between the second end of the elastic member 400 and the adjusting tooth 300 of the bolt head 121, the adjusting device can avoid the second end of the elastic member 400 when the adjusting tooth 300 is moved, preventing the second end of the elastic member 400 from abutting against the driving tooth 830 of the adjusting device and affecting the rotation of the adjusting device, thereby making the prefabricated component connecting device of this embodiment easy to adjust and assemble.

[0036] In some embodiments, such as Figure 1 , 2 As shown, a pressure plate 410 is fixedly connected to the second end of the elastic element 400. The pressure plate 410 abuts between the elastic element 400 and the head 121. The adjusting tooth 300 is located at the edge of the head 121. An annular curved portion is provided at the position corresponding to the adjusting tooth 300 on the pressure plate 410. A gap for the insertion of an adjusting device is formed between the annular curved portion and the adjusting tooth 300. The annular region 411 shown can be configured as follows: Figure 1The slope bend shown can also be set as follows: Figure 2 The curved surface shown can, of course, be set as a recessed structure of other shapes, so that the head 121 of the bolt 120 forms a clearance space between the elastic element 400 and the adjusting tooth 300, so that the adjusting device can be inserted into the adjusting tooth 300.

[0037] In some embodiments, such as Figure 3 , 4 As shown in Figure 6, the adjusting tooth 300 is located at the edge of the head 121 of the bolt 120. A contact portion 301 is formed at the center of the head 121, and the adjusting tooth 300 is located outside the contact portion 301. The second end of the elastic member 400 abuts against the contact portion 301. The contact portion 301 is formed at the center of the head 121 of the bolt 120, and the diameter of the second end of the elastic member 400 is smaller than that of the contact portion 301, so that the spring will not interfere with the rotation of the adjusting device when the adjusting tooth 300 is adjusted. This embodiment does not limit the specific shape of the elastic member 400. Figure 3 , 4 The diagram shows some reference structures of the elastic element 400.

[0038] Specifically, such as Figure 1 , 2 As shown, the bolt 120 is provided with an adjusting tooth 300, and the nut 220 is provided with an anti-rotation limiting part 320. The anti-rotation limiting part 320 is used to restrict the nut 220 and the bolt 120 from rotating synchronously when the adjusting tooth 300 is adjusted. The adjusting device moves the adjusting tooth 300 to make the bolt 120 rotate, and the anti-rotation limiting part 320 prevents the nut 220 from rotating along with it. That is, by setting the adjusting tooth 300 and the anti-rotation limiting part 320, the bolt 120 and the nut 220 can rotate relative to each other when the adjusting tooth 300 is adjusted, so that the nut 220 is tightened on the bolt 120, thereby forming a stable connection between the male connector 100 and the female connector 200.

[0039] In some embodiments, such as Figure 7As shown, the nut 220 is wedge-shaped with an inclined surface on its outer side. The inner side of the second connector 230 is fitted onto the outer side of the nut 220, and a conical cavity is formed in the second connector 230 to mate with the nut 220. When the nut 220 is tightened on the bolt 120, the wedge-shaped inclined surface of the nut 220 fits into the conical cavity of the second connector 230. The friction between the outer side of the nut 220 and the inner side of the second connector 230 prevents rotation between the nut 220 and the second connector 230. The nut 220 is also provided with an anti-rotation limiting part 320, which is a through groove arranged along the axial direction of the nut 220. The through groove gradually narrows during the tightening process of the nut 220, so that the diameter of the nut 220 gradually decreases. When an axial force is applied, the nut 220 and the second connector 230 are gradually pressed together, and the friction gradually increases, preventing rotation.

[0040] In some embodiments, such as Figure 5 As shown, the nut 220 is a common hexagonal nut, and the mounting cavity 211 of the female sleeve 210 has an anti-rotation limiting part 320 that cooperates with the hexagonal nut 220, so that when the bolt 120 rotates, the nut 220 does not rotate with the bolt 120, so that the nut 220 can be tightened or loosened relative to the bolt 120.

[0041] In some embodiments, such as Figure 6 As shown, the adjusting tooth 300 includes a tooth and a tooth groove. The protruding teeth and tooth grooves are evenly staggered along the circumferential direction of the bolt 120. The head 121 of the bolt 120 is provided with adjusting teeth 300 evenly staggered along the circumferential direction. The adjusting tooth 300 includes staggered protruding teeth and tooth grooves.

[0042] In some embodiments, the male connector assembly 100 further includes a first connector 130, which is detachably fixedly connected to the male sleeve 110, and the first connector 130 is sleeved with the bolt 120 to confine the head 121 of the bolt 120 within the receiving cavity 111. In this embodiment, the first connector 130 and the male sleeve 110 are threadedly connected; in other embodiments, the first connector 130 and the male sleeve 110 may also be connected by a snap-fit ​​connection that prevents relative rotation.

[0043] In some embodiments, the female connector assembly 200 further includes a second connector 230, which is detachably fixedly connected to the opening of the mounting cavity 211 of the female connector sleeve 210 to confine the nut 220 within the mounting cavity 211. In this embodiment, the second connector 230 and the female connector sleeve 210 are threaded together. In other embodiments, the second connector 230 and the female connector sleeve 210 may also be configured as a non-rotatable snap-fit ​​connection.

[0044] This embodiment also proposes a building structure, including a first prefabricated component and a second prefabricated component. The first prefabricated component and the second prefabricated component are assembled and connected by a prefabricated component connecting device as described in any of the above embodiments. The first prefabricated component is provided with the male connector 100, and the second prefabricated component is provided with the female connector 200. One of the first prefabricated component and the second prefabricated component is provided with an adjustment through hole corresponding to and communicating with the adjustment hole 310.

[0045] like Figure 8 As shown, this embodiment also proposes an adjustment device for adjusting the prefabricated component connection device as described in any of the above embodiments. The device includes a handle 810 and an adjustment rod 820 that are fixedly connected. The end of the adjustment rod 820 is provided with a drive tooth 830, which meshes with the adjustment tooth 820.

[0046] In some embodiments, the bolt 120 is provided with an adjusting tooth 300, and the driving tooth 830 of the adjusting device engages with the adjusting tooth 300 on the top of the bolt 120. By rotating the adjusting device, the nut 220 is rotated and moved on the bolt 120, thereby tightening or loosening the nut 220 and the bolt 120 relative to each other.

[0047] In summary, by providing a clearance space between the second end of the elastic member 400 and the adjusting tooth 300 of the bolt head 121, the above embodiment allows the adjusting device to avoid the second end of the elastic member 400 when the adjusting tooth 300 is moved, preventing the second end of the elastic member 400 from abutting against the driving tooth 830 of the adjusting device and affecting the rotation of the adjusting device. This makes the prefabricated component connecting device of this embodiment easy to adjust and assemble.

[0048] The foregoing has described specific embodiments of this application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims may be performed in a different order than that shown in the embodiments and may still achieve the desired results. Furthermore, the processes depicted in the drawings do not necessarily require the specific or sequential order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
