[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Such as Figures 1 to 11As shown in the figure, a connecting member for installing precast wall panels includes a wall body 1. On one side of the wall body 1, a wall panel body 2 is installed. At one end where the wall body 1 and the wall panel body 2 are close to each other, there are a number of placement grooves 4. The placement grooves 4 correspond to each other one by one and overlap with each other. Connecting mechanisms 3 are respectively installed inside the overlapping placement grooves 4. The connecting mechanism 3 includes a connecting box 301. The connecting box 301 is snap-fitted inside the placement groove 4. At both ends inside the connecting box 301, transmission boxes 308 are respectively installed. At one end far from each other and at the upper and lower ends inside the transmission box 308, lead screws 311 are respectively movably penetrated and installed. At one end of the lead screw 311 located inside the transmission box 308, second bevel gears 312 are respectively installed. The second bevel gears 312 are meshed with each other. On the outer side of the rod body of the lead screw 311, turntables 313 are respectively movably penetrated and installed. On one side of the turntable 313 far from the transmission box 308, a number of first annular chutes 314 are respectively provided. Inside the first annular chutes 314, a number of bolts 316 are respectively snap-fitted and installed. On one side far from each other and at the upper and lower sides inside the placement groove 4, a number of threaded holes 317 are respectively provided. The bolts 316 respectively movably penetrate inside the connecting box 301 and are threadedly snap-fitted inside the threaded holes 317.

[0020] As Figure 8 shown, inside the connecting box 301, a second transmission shaft 306 is movably installed in the middle. At both ends of the rod body of the second transmission shaft 306, they are respectively movably penetrated and installed inside the transmission box 308. At one end of the second transmission shaft 306 located inside the transmission box 308, first bevel gears 310 are respectively installed. The first bevel gears 310 are meshed with the second bevel gears 312. At the lower end inside the connecting box 301, a first transmission shaft 302 is movably penetrated and installed. At the front end of the rod body of the first transmission shaft 302, a movable disk 303 is installed. The movable disk 303 is movably installed on the front surface of the connecting box 301. On the front surface of the movable disk 303, an internal hexagonal groove 304 is provided. On the outer side of the rod body of the first transmission shaft 302, a worm 305 is sleeved and installed. On the outer side of the rod body of the second transmission shaft 306, a worm gear 307 is sleeved and installed. The worm 305 is meshed with the worm gear 307. Figure 10 As

[0021] The user inserts an electric external hexagonal wrench into the internal hexagonal groove 304 on the front surface of the movable disk 303 to drive the first transmission shaft 302. Then, the worm 305 on the outer side of the rod body of the first transmission shaft 302 is meshed with the worm gear 307 on the outer side of the rod body of the second transmission shaft 306 to drive the second transmission shaft 306 to rotate. Then, the first bevel gear 310 at one end of the second transmission shaft 306 located inside the transmission box 308 is meshed with the second bevel gear 312 at one end of the lead screw 311 located inside the transmission box 308, thereby driving the lead screw 311 to rotate; The worm gear 307, the worm 305, the first bevel gear 310 and the second bevel gear 312 are used for transmission, thereby realizing effective transmission of power and conversion of direction. This multi-stage transmission method enables the user to rotate the screw rod 311 by simply operating an electric hexagonal wrench. The operation is simple and the power can be accurately transmitted to the screw rod 311, thereby providing power support for the subsequent tightening of the bolt 316.

[0022] like Figure 10 and Figure 11 As shown, a gear ring 315 is installed inside each first annular groove 314, and a gear 318 is installed on one end of each bolt 316 located inside the first annular groove 314. The gear 318 is meshingly connected with the gear ring 315. A locking groove 319 is provided at both ends of each screw rod 311, and a locking block 320 is installed at one end of the turntable 313 close to the locking groove 319. The locking blocks 320 are respectively locked inside the locking groove 319.

[0023] When the screw rod 311 rotates, the engaging grooves 319 at both ends cooperate with the engaging blocks 320 on the rotating disk 313 to drive the rotating disk 313 to revolve, and then a gear ring 315 is installed in the first annular groove 314 on the side of the rotating disk 313 away from the transmission box 308, and the gear 318 sleeved on one end of the bolt 316 located inside the first annular groove 314 meshes with the gear ring 315, so that when the rotating disk 313 rotates, the gear ring 315 and the gear 318 are meshed to control the bolt 316 to rotate. The revolution of the turntable 313 can be converted into the rotation of the bolt 316, which ingeniously realizes the transmission of power and the conversion of motion forms, ensures that the bolt 316 can be smoothly screwed into the threaded hole 317, and lays the foundation for the multi-directional fastening connection between the wall 1 and the wall panel body 2.

[0024] like Figure 10 and Figure 11 As shown, a push plate 323 is installed on the outer side of the rod body of each screw rod 311 through a thread, and the push plates 323 are movably located between the turntable 313 and the transmission box 308, and an annular slider 321 is installed on one end of each push plate 323 close to the turntable 313, and a second annular groove 322 is provided on one side of the turntable 313 close to the push plate 323, and the annular slider 321 is respectively snap-fitted and installed inside the second annular groove 322.

[0025] A push plate 323 is installed through the thread on the outer side of the rod body of the lead screw 311. The annular slider 321 at one end of the push plate 323 close to the turntable 313 is engaged in the second annular chute 322 of the turntable 313. Thus, when the lead screw 311 rotates, under the action of the thread of the lead screw 311, the push plate 323 moves along the lead screw 311. And through the cooperation of the annular slider 321 and the second annular chute 322, it can not only push the turntable 313 to move, but also will not prevent the turntable 313 from revolving; Through the coordinated work of the push plate 323 and the turntable 313, the bolt 316 can not only rotate on its own axis, but also move closer to the threaded hole 317 along with the turntable 313, ensuring that the bolt 316 can be smoothly screwed into the threaded hole 317, further enhancing the reliability and stability of the connection.

[0026] As Figures 9 to 11 shown, on both sides of each push plate 323, extension frames 326 are respectively installed. At the front and rear ends of both sides inside the connection box 301, first guiding rods 324 are respectively installed. The rod bodies of the first guiding rods 324 are respectively movably penetrated and installed inside the extension frames 326 on both sides. On the front and rear sides of the transmission box 308, support blocks 309 are respectively installed. The support blocks 309 are respectively fixedly installed inside the connection box 301. At the ends of the support blocks 309 far away from the transmission box 308, second guiding rods 325 are respectively fixedly installed. The rod bodies of the second guiding rods 325 are respectively movably penetrated and installed inside the extension frames 326 at the upper and lower ends.

[0027] Extension frames 326 are installed on both sides of the push plate 323. The first guiding rods 324 at the front and rear ends of both sides inside the connection box 301 movably penetrate the extension frames 326 on both sides. The second guiding rods 325 on the support blocks 309 on the front and rear sides of the transmission box 308 movably penetrate the extension frames 326 at the upper and lower ends. Thus, during the movement of the push plate 323, the first guiding rods 324 and the second guiding rods 325 play a guiding role for the extension frames 326, ensuring the smooth movement of the push plate 323; Through the arrangement of the first guiding rods 324 and the second guiding rods 325, it effectively avoids the deviation or shaking of the push plate 323 during the movement process, ensures that the push plate 323 can stably push the turntable 313, and further ensures that the bolt 316 can be accurately screwed into the threaded hole 317, improving the accuracy and stability of the connection.

[0028] The working principle of this connecting component for precast wall panel installation: In use, first, the user places the connection box 301 into the overlapping placement grooves 4. Then, the user inserts an electric hexagon wrench into the hexagon socket groove 304 on the front surface of the movable disc 303, and the electric hexagon wrench drives the first transmission shaft 302 to rotate. Then, the worm 305 on the outer side of the rod body of the first transmission shaft 302 rotates and meshes with the worm gear 307 on the outer side of the rod body of the second transmission shaft 306, driving the second transmission shaft 306 to rotate. Then, the first helical gear 310 at one end of the second transmission shaft 306 inside the transmission box 308 meshes with the second helical gear 312 at one end of the lead screw 311 inside the transmission box 308, causing the lead screw 311 to rotate. When the lead screw 311 rotates, the engaging grooves 319 at both ends thereof cooperate with the engaging blocks 320 on the turntable 313, driving the turntable 313 to revolve. There is a toothed ring 315 installed in the first annular sliding groove 314 on the side of the turntable 313 away from the transmission box 308. At the same time, the gear 318 sleeved at one end of the bolt 316 inside the first annular sliding groove 314 meshes with the toothed ring 315. Thus, when the turntable 313 revolves, through the meshing of the toothed ring 315 and the gear 318, the bolt 316 is controlled to rotate. When the lead screw 311 rotates, the push plate 323 moves along the lead screw 311 under the action of the thread of the lead screw 311. At the same time, through the cooperation of the annular slider 321 and the second annular sliding groove 322, the push plate 323 can not only push the turntable 313 to move but also does not prevent the turntable 313 from revolving. This enables the bolt 316 to approach the threaded hole 317 along with the turntable 313 while rotating. Then, during the movement of the push plate 323, the first guide rod 324 and the second guide rod 325 play a guiding role for the extension frame 326, ensuring the smooth movement of the push plate 323, and further ensuring that the bolt 316 can be accurately screwed into the threaded holes 317 on each side of the placement groove 4, realizing the multi-directional fastening connection between the wall body 1 and the wallboard body 2.

[0029] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
