Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1-6 , a connecting piece for prefabricated plate of fabricated building, including connecting piece one 1, connecting piece one 1 one side fixed mounting has mounting block 2, the inside of mounting block 2 is provided with locking assembly 3, the inside of mounting block 2 is fixedly installed with limit block two 4, the inside of mounting block 2 is fixedly installed with limit block three 5, the outside of mounting block 2 is provided with guide slot 6, the bottom of mounting block 2 is fixedly installed with limit block four 7, connecting piece one 1 is insertedly installed with connecting piece two 8 on the side close to mounting block 2, the top of connecting piece two 8 close to connecting piece one 1 side is provided with mounting groove 9, the bottom of mounting groove 9 is provided with limit groove one 10, the side away from mounting block 2 of connecting piece one 1 is provided with positioning groove 12, the top and bottom of connecting piece one 1 are provided with threaded hole 13;

[0025] The locking assembly 3 comprises a locking knob 301, a pressing block 302, a moving block 303, a spring 304 and a limiting block one 305. The top of the mounting block 2 is rotationally connected with the locking knob 301. The bottom of the locking knob 301 is fixedly installed with the pressing block 302. The side, away from the locking knob 301, of the pressing block 302 is provided with the moving block 303. The top of the side, away from the pressing block 302, of the moving block 303 is provided with the spring 304.

[0026] Please refer to Figures 1-6 , the mounting block 2 and the mounting groove 9 are in a plug-in connection in the diagram, and the limiting block four 7 and the limiting groove two 11 are in a plug-in connection.

[0027] In this embodiment: through the plug-in connection between the mounting block 2 and the mounting groove 9, when the connecting piece one 1 and the connecting piece two 8 are installed, the limiting block four 7 is inserted into the limiting groove two 11, and the mounting block 2 is inserted into the mounting groove 9. The mounting block 2 is fixed inside the mounting groove 9 and thus cannot be deviated in the horizontal direction, improving the stability.

[0028] Working principle: when the connecting piece one 1 and the connecting piece two 8 are installed, the limiting block four 7 is inserted into the limiting groove two 11, and the mounting block 2 is inserted into the mounting groove 9, so that the mounting block 2 is fixed inside the mounting groove 9. When the structure is locked, the locking knob 301 is rotated, so that the pressing block 302 rotates together. The side, away from the locking knob 301, of the pressing block 302 rotates and cooperates with the side, close to the locking knob 301, of the moving block 303. At this time, the force exerted by the moving block 303 is greater than the elastic force exerted by the spring 304 on the moving block 303, so that the pressing block 302 can extrude the moving block 303 to move away from the pressing block 302. The moving block 303 drives the limiting block one 305 to move, cooperates with the guide groove 6, and makes the limiting block one 305 inserted into the limiting groove one 10. At this time, the limiting block one 305 cooperates with the limiting groove one 10 after being locked, and can limit the mounting block 2, so that the connecting piece one 1 and the connecting piece two 8 are fixed. When the structure is unlocked, the locking knob 301 is continuously rotated, so that the side, away from the locking knob 301, of the pressing block 302 continues to rotate along the side, close to the locking knob 301, of the moving block 303, so that the side, away from the locking knob 301, of the pressing block 302 and the side, close to the locking knob 301, of the moving block 303 are no longer in close contact. The force exerted by the pressing block 302 on the moving block 303 disappears. At this time, the counterforce exerted by the spring 304 on the moving block 303 makes the moving block 303 drive the limiting block one 305 to reset, and the structure is unlocked. When the connecting piece body and the building prefabricated slab are installed, the building prefabricated slab can be quickly positioned through the positioning groove 12, so as to facilitate the installation of the building prefabricated slab through the threaded hole 13.

[0029] Embodiment 2

[0030] As shown in Figures 1-6 , the embodiment is further illustrated by the example 1, and the two same hidden locking knobs 301 are arranged in the diagram.

[0031] In the embodiment, the hidden design of the locking knob 301 prevents the locking knob 301 from being accidentally touched during the installation process, prevents accidents from occurring during the installation process, and thus prevents the structure from loosening. Meanwhile, the hidden design saves space and avoids affecting the installation.

[0032] As shown in Figures 1-6 , the side of the extrusion block 302 away from the locking knob 301 is arc-shaped, the side of the extrusion block 302 away from the locking knob 301 is matched with the side of the moving block 303 close to the locking knob 301, the side of the spring 304 away from the locking knob 301 is abutted with the limiting block 2 4, and the side of the spring 304 close to the locking knob 301 is abutted with the moving block 303.

[0033] In the embodiment, when the structure is locked, the extrusion block 302 is rotated by rotating the locking knob 301, the side of the extrusion block 302 away from the locking knob 301 is rotated and matched with the side of the moving block 303 close to the locking knob 301, the force applied by the moving block 303 is greater than the elastic force applied by the spring 304 to the moving block 303, the extrusion block 302 can extrude the moving block 303 to move away from the extrusion block 302, and when the structure is unlocked, the locking knob 301 is continuously rotated, the side of the extrusion block 302 away from the locking knob 301 is continuously rotated along the side of the moving block 303 close to the locking knob 301, so that the side of the extrusion block 302 away from the locking knob 301 and the side of the moving block 303 close to the locking knob 301 are no longer matched, the force applied by the extrusion block 302 to the moving block 303 disappears, and the counterforce applied by the spring 304 to the moving block 303 resets the moving block 303, thereby facilitating the quick locking and unlocking of the structure and facilitating the disassembly, assembly and maintenance.

[0034] As shown in Figures 1-6 , the moving block 303 and the limiting block 1 305 are fixedly installed, the limiting block 3 5 is provided in multiple groups, each group of the limiting block 3 5 is provided with two same limiting blocks 3 5, and the limiting slots formed by the two limiting blocks 3 5 are in sliding connection with the moving block 303.

[0036] Please refer to Figures 1-6 , the limiting block one 305 is insertedly installed in the limiting groove one 10, the limiting block one 305 penetrates the guide groove 6 and extends to the inside of the limiting groove one 10.

[0037] In the embodiment, when locking the structure, the moving block 303 drives the limiting block one 305 to move, cooperates with the guide groove 6, so that the limiting block one 305 is inserted into the inside of the limiting groove one 10, at this time, the limiting block one 305 cooperates with the limiting groove one 10 after locking, can limit the installation block 2, so that the connecting piece one 1 and the connecting piece two 8 are fixed, improve the stability of the overall structure.

[0038] Please refer to Figures 1-6 , the plurality of positioning grooves 12 and threaded holes 13 are arranged, and the plurality of positioning grooves 12 and threaded holes 13 are respectively located on the side of the connecting piece one 1 and the connecting piece two 8 away from the installation block 2.

[0039] In the embodiment, the plurality of positioning grooves 12 and threaded holes 13 are arranged, when installing the connecting piece body and the building prefabricated plate, the building prefabricated plate can be quickly positioned through the positioning groove 12, so that the building prefabricated plate is conveniently installed through the threaded hole 13, and the practicability is improved.
