[0002] A prefabricated building refers to a building in which a large amount of on-site operation work in the traditional construction method is transferred to a factory. Building components and fittings are processed and manufactured in the factory and transported to the construction site of the building, and then assembled and installed on-site through a reliable connection method.

[0003] In the process of using existing prefabricated buildings, the connection between building boards often adopts methods such as welding, bolt connection or mortise and tenon connection. Although the connection requirements are met to a certain extent, there are often problems such as complex construction, high cost and poor flexibility. Especially when facing building boards with different sizes, shapes and fixed hole positions, these traditional methods are difficult to quickly and accurately achieve plug-in locking and positioning. Therefore, we propose a plug-in locking mechanism at the joint of a prefabricated building. Summary of the Utility Model

[0025] Please refer to Figures 1 - 3 , the present invention provides a technical solution: an insertion and locking mechanism for the connection of prefabricated buildings, including:

[0026] A locking frame 1, at the bottom of the locking frame 1, two sliding grooves 14 are opened, and both sliding grooves 14 communicate with the inside of the locking frame 1;

[0027] An insertion and locking structure, which is located on the locking frame 1;

[0028] The plug-in locking structure includes a bidirectional screw 11, two sliding plates 10 and two locking plates 2. The bidirectional screw 11 is rotatably connected inside the locking frame 1. The two sliding plates 10 are both threadedly sleeved on the outer surface of the bidirectional screw 11. The two sliding plates 10 are both slidably connected in the corresponding sliding grooves 14. The bottoms of the two sliding plates 10 are both provided with limiting sliding grooves 13. The inside of the two limiting sliding grooves 13 are both slidably connected with limiting sliders 12. The two locking plates 2 are both fixedly connected to the bottoms of the corresponding limiting sliders 12. The inside of the two limiting sliders 12 are both provided with cavities. The opposite surfaces of the two locking plates 2 are both provided with locking holes 8.

[0029] The plug-in locking structure further includes two positioning plates 5 and two positioning bolts 3. The two positioning plates 5 are both slidably connected inside the corresponding locking plates 2. The one sides of the two positioning plates 5 are both provided with a plurality of threaded holes 7. The two positioning bolts 3 are both rotatably connected to one side of the locking plates 2. One ends of the two positioning bolts 3 both threadedly penetrate through one side of the corresponding locking plates 2 and are threadedly connected to the corresponding threaded holes 7. The opposite surfaces of the two positioning plates 5 are both provided with plug-in holes 4 for facilitating positioning.

[0030] The number of the plug-in locking structures is two, and the two plug-in locking structures are respectively installed corresponding to the two sliding grooves 14.

[0031] One side of the locking frame 1 is rotatably connected with a rotating disk 6. One end of the bidirectional screw 11 close to the rotating disk 6 rotatably extends to the outside of the locking frame 1. The rotating disk 6 is fixedly connected to the corresponding bidirectional screw 11. Synchronous wheels 15 are both fixedly sleeved on the outer surfaces of the two bidirectional screws 11. A synchronous belt 9 is drivingly sleeved on the outer surfaces of the two synchronous wheels 15. The synchronous belt 9 is located inside the locking frame 1.

[0032] Further, when using the device, the operator makes the bottom of the locking frame 1 contact the tops of two mutually attached building boards. Subsequently, the rotating disk 6 is rotated. The rotating disk 6 will drive the corresponding bidirectional screw 11 to rotate. Under the synchronous drive of the synchronous belt 9, the two bidirectional screws 11 can rotate synchronously. The rotation of the bidirectional screw 11 will drive the corresponding two sliding plates 10 to move in opposite directions, so as to facilitate the two locking plates 2 to clamp and position the two attached building boards. By the operator screwing the positioning bolts 3, the positioning bolts 3 can be threadedly connected to the threaded holes 7 at different heights according to the positions where the boards are bolt-fixed, so as to facilitate positioning the punching positions of the two boards through the two plug-in holes 4, so that the punched boards can be installed with bolts for the two building boards. And after the two locking plates 2 clamp the boards, bolts can be passed through the two locking holes 8, so as to facilitate fixing the two locking plates 2. Subsequently, the locking frame 1 can be horizontally pushed, so that the limiting sliders 12 are separated from the corresponding limiting sliding grooves 13, and further facilitate separating the locking frame 1 from the locking plates 2, so as to facilitate subsequent welding work.

[0033] With the cooperation of the locking plate 2, positioning bolts 3, positioning plate 5, sliding plates 10, bidirectional screw 11 and synchronous belt 9, the positioning bolts 3 can be threadedly connected to the threaded holes 7 at different heights according to the positions where the plates are bolt-fixed, so as to facilitate positioning the punching positions of the two plates through the two insertion holes 4. At the same time, after the two locking plates 2 clamp the plates, bolts can pass through the two locking holes 8, which is convenient for fixing the two locking plates 2, and then facilitating the separation of the locking frame 1 from the locking plate 2, thus facilitating subsequent welding work and further facilitating the quick and accurate insertion and locking positioning of the two building plates.

[0034] Working principle: The operator makes the bottom of the locking frame 1 contact the tops of two mutually attached building plates. Subsequently, rotate the rotating disc 6, and the rotating disc 6 will drive the corresponding bidirectional screw 11 to rotate. Under the synchronous transmission of the synchronous belt 9, the two bidirectional screws 11 can rotate synchronously. The rotation of the bidirectional screw 11 will drive the corresponding two sliding plates 10 to move in opposite directions, so as to facilitate the two locking plates 2 to clamp and position the two attached building plates. By the operator screwing the positioning bolts 3, the positioning bolts 3 can be threadedly connected to the threaded holes 7 at different heights according to the positions where the plates are bolt-fixed, so as to facilitate positioning the punching positions of the two plates through the two insertion holes 4, enabling the punched plates to be installed with bolts for the two building plates. And after the two locking plates 2 clamp the plates, bolts can pass through the two locking holes 8, which is convenient for fixing the two locking plates 2. Subsequently, the locking frame 1 can be pushed horizontally, so that the limit slider 12 is disengaged from the corresponding limit chute 13, and then facilitating the separation of the locking frame 1 from the locking plate 2, thus facilitating subsequent welding work.

[0035] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the purpose of the present invention.
