[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6This utility model discloses an electrical wiring box, comprising a box body 1. Several first threaded holes 2 are provided on the side wall of the box body 1, each threadedly connected to a threaded tube 3. A connecting rod 4 is rotatably connected inside the threaded tube 3. The threaded tube 3 and the connecting rod 4 are installed on the box body 1 by means of the threaded connection between the threaded tube 3 and the first threaded holes 2 of the box body 1, facilitating disassembly. Each connecting rod 4 has a first fixing ring 5 at its front end and a second fixing ring 6 detachably connected to the first fixing ring 5. The first fixing ring 5 and the second fixing ring 6 surround the outside of the wire to be clamped. A screw 7 passes through one end of the second fixing ring 6 and is rotatably connected to one end of a clamping and fixing device 8. The screw 7 is threadedly connected at the penetration point of the second fixing ring 6, facilitating rotation. The screw 7 is moved on the second fixing ring 6. Under the thrust of the screw 7, the clamping and fixing device 8 forms an adjustable space with the inner wall of the first fixing ring 5 for clamping the wire. The screw 7 is rotated, and the screw 7 rotates through the second fixing ring 6, which then drives the clamping and fixing device 8 to approach the wire until it is tightly attached to the outer wall of the wire, thereby fixing the wire in conjunction with the first fixing ring 5. A guide rod 9 is also connected through the second fixing ring 6. The guide rod 9 is located on both sides of the screw 7 and passes through the second fixing ring 6 and is fixedly connected to the clamping and fixing device 8. The guide rod 9 slides along one end of the clamping and fixing device 8 through the second fixing ring 6, so that the clamping and fixing device 8 will not rotate.

[0023] One end of the first fixing ring 5 is provided with a mounting groove 10 that engages with the mounting plate 11 on the second fixing ring 6, and the other end is provided with a mounting plate 11 that engages with the mounting groove 10 on the second fixing ring 6. By engaging the mounting plate 11 into the mounting groove 10 at one end of the first fixing ring 5, the first fixing ring 5 and the second fixing ring 6 are connected together for installation.

[0024] Mounting plate 11 is fixed to the end of the second fixing ring 6 and is integrally formed with the second fixing ring 6. The two are fixed together, so that when mounting plate 11 is inserted into mounting groove 10 of first fixing ring 5, the second fixing ring 6 is fixed on the first fixing ring 5, thereby fixing the two together.

[0025] The mounting plate 11 has a T-shaped cross-section, which allows the mounting plate 11 to move up and down only along the axis of the mounting groove 10.

[0026] The length of screw 7 is greater than the length of guide rod 9, so that when the operator rotates screw 7, their hand will not touch guide rod 9, thus affecting the normal rotation of screw 7.

[0027] A sealing cover 12 is hinged to the box body 1. A through groove is provided on the sealing cover 12, and a protective window is installed in the through groove. The protective window plays a certain protective role.

[0028] In summary, when using this electrical junction box, the operator inserts the mounting plate 11 on one side of the second fixing ring 66 into the mounting groove 10 of the first fixing ring 5, and installs the second fixing ring 6 on the first fixing ring 5. Then, the wires inside the box 1 are passed through the first fixing ring 5 and the second fixing ring 6. At this time, the operator grasps the end of the screw 7 and rotates it. The screw 7 rotates on the second fixing ring 6. As the screw 7 rotates, it drives the clamping and fixing device 8 to approach the wire. At this time, the guide rods 9 on both sides of the clamping and fixing device 8 slide through the second fixing ring 6, so that the clamping and fixing device 8 does not rotate. It moves horizontally closer to the wire until it is tightly attached to the outer wall of the wire, thus cooperating with the first fixing ring 5 to fix the wire. At this time, the wire fixing work is completed, and the sealing cover 12 can be closed.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
