[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example 1

[0019] Reference Figure 1-3 An electrical junction box comprises a box body 2, a box cover 1 is connected to the box body 2 through a fixing mechanism, a sealing gasket is arranged between the box cover 1 and the box body 2, a plurality of pairs of threading tubes 5 are connected to the box body 2, a first sealing block 11 is fixedly connected to the plurality of pairs of threading tubes 5, a connecting shell 9 is connected to the plurality of pairs of threading tubes 5, a second sealing block 12 is connected to the connecting shell 9 through an adjusting mechanism, abutting semicircular holes 13 are arranged between the first sealing block 11 and the second sealing block 12, and the first sealing block 11 and the second sealing block 12 are made of rubber material.

[0020] By passing the wire through the abutting semicircular hole 13, the adjustment mechanism makes the first sealing block 11 and the second sealing block 12 abut against each other, and the wire is wrapped, thereby achieving a sealing effect and preventing the entry of moisture. At the same time, since the second sealing block 12 is adjustable, wires of different diameters can be abutted between the first sealing block 11 and the second sealing block 12, and the wires are abutted and fixedly sealed, and at the same time, the first sealing block 11 and the second sealing block 12 are abutted against each other.

[0021] The adjusting mechanism comprises a threaded rod 10 , to which a knob is fixedly connected for holding and driving the threaded rod 10 to rotate.

[0022] The threaded rod 10 is rotatably connected to the second sealing block 12 through bearings, and the bearings are all thrust ball bearings. The second sealing block 12 abuts against the inner wall of the connecting shell 9, and the threaded rod 10 is threadedly connected to the connecting shell 9. By rotating the threaded rod 10, the second sealing block 12 will be driven to move and the position of the second sealing block 12 will be adjusted.

[0023] Example 2

[0024] In Example 1, the box cover 1 is generally fixed by screws, which makes it inconvenient to disassemble the box cover 1 and maintain the interior. Figure 1-3 As another preferred embodiment of the utility model, on the basis of embodiment 1, a connecting ear 8 is fixedly connected to the box body 2, and a rotating shaft 6 is rotatably connected to the connecting ear 8 through a bearing, and a contact block 7 is fixedly connected to the rotating shaft 6. A card slot 4 is provided on the box cover 1, and an inclined surface is provided in the card slot 4. The contact block 7 contacts the inclined surface. The box body 2 and the box cover 1 are limited by a limiting mechanism. By rotating the contact block 7, the contact block 7 will contact the inclined surface of the card slot 4. As the rotation continues, the contact block 7 contacts the card slot 4 more tightly, thereby fixing the box cover 1. When disassembly is required, the contact block 7 can be rotated and moved out of the card slot 4 by rotating the contact block 7.

[0025] The limiting mechanism comprises a boss 3 , which is fixedly connected to the box cover 1 and abuts against the box body 2 . The boss 3 is used to limit the box cover 1 in the lateral direction.

[0026] When in use, the wires are connected by passing them through the wire threading tube 5, and then the threaded rod 10 is rotated to drive the second sealing block 12 to move, and the position of the second sealing block 12 is adjusted. The first sealing block 11 and the second sealing block 12 abut and seal the wires, and at the same time, the first sealing block 11 and the second sealing block 12 abut, and then the abutment block 7 is rotated to make the abutment block 7 abut against the inclined surface of the card slot 4. As the rotation continues, the abutment block 7 abuts against the card slot 4 more tightly, thereby fixing the box cover 1.
