It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1

[0033] Reference Figures 1-6 An electrical junction box includes a fixed box 1. A cover 2 is bolted to the top of the fixed box 1, so that the cover 2 can be installed on the top of the fixed box 1 by bolts, and the top of the fixed box 1 can be closed by the cover 2. Inlet holes 3 are evenly distributed inside the bottom of both sides of the fixed box 1. The inlet holes 3 are threaded with a closing plug 4. The diameters of multiple inlet holes 3 on the same side are different, so that wires of different diameters can enter the interior of the fixed box 1 through the corresponding inlet holes 3 for connection, and the closing plug 4 closes the inlet holes 3 that do not have wires passing through.

[0034] In other embodiments, symmetrical heat dissipation holes may be provided inside the fixing box 1 or the cover 2, depending on the actual application needs, to facilitate heat dissipation of the internal circuitry of the fixing box 1.

[0035] The top of the fixed box 1 is provided with a limiting post 6. The top of both ends of the limiting post 6 are slidably connected with positioning plates 8, so that the limiting post 6 can rotate between the two positioning plates 8, but cannot be raised or lowered. The positioning plates 8 are slidably connected to the fixed box 1. The outer side of the top of the limiting post 6 is provided with a positioning annular groove 7. The positioning plates 8 and the limiting post 6 are slidably connected through the positioning annular groove 7, so that the adjacent positions of the two positioning plates 8 can enter the inner side of the positioning annular groove 7. The top of the fixed box 1 is provided with positioning grooves 5 on both sides. The positioning plates 8 and the fixed box 1 are slidably connected through the positioning grooves 5, so that when the two positioning plates 8 are close together, they can slide into the inner side of the positioning grooves 5, thereby supporting the height of the limiting post 6.

[0036] A connecting plate 11 is fixed to the bottom of the limiting post 6. Both ends of the bottom of the connecting plate 11 are slidably connected to clamping plates 15, so that the two clamping plates 15 can clamp the line entering through the inlet hole 3. An adjustment mechanism for driving the two clamping plates 15 to move in opposite directions is installed inside the connecting plate 11. The adjustment mechanism includes a clamping drive motor 16, a first bevel gear 17, a second bevel gear 18 and a rotating shaft 19. The clamping drive motor 16 is fixed inside the connecting plate 11. The output end of the clamping drive motor 16 is connected to the first bevel gear 17. The second bevel gear 18 is meshed on one side of the first bevel gear 17. The rotating shaft 19 is fixed inside the second bevel gear 18. The rotating shaft 19 is rotatably connected to the connecting plate 11. Threaded sections 20 are opened on the outer side of the rotating shaft 19 and at both ends of the second bevel gear 18. The threads of the two threaded sections 20 are opposite in direction. The outer side of the threaded sections 20 is threadedly connected to the clamping plates 15, so that the two threaded sections 20 with opposite directions of thread rotate at the same time, causing the two clamping plates 15 to move in opposite directions.

[0037] Preferably, the bottom of each of the two clamping plates 15 is provided with anti-slip texture, which can make the clamping of the line between the two clamping plates 15 more stable.

[0038] The usage process of the electrical junction box provided by this utility model is as follows: During use, depending on the diameter of the wire to be wired, select the corresponding closing plug 4 to rotate, so that the closing plug 4 disengages from the threaded inlet hole 3, and then let the wire enter the interior of the fixed box 1 through the inlet hole 3 for wiring. Then, let the connected wire be located between the two clamping plates 15. At this time, install the positioning plate 8 at both ends of the positioning annular groove 7 on the limiting post 6, and then let the positioning plate 8 enter the inner side of the positioning groove 5, so that the limiting post 6 descends inside the fixed box 1, and the clamping plate 15 is just located at both ends of the connected wire. Then, the clamping drive motor 16 works to drive the first bevel gear 17 to rotate, and the rotation of the first bevel gear 17 drives the meshing second bevel gear 18 to drive the rotating shaft 19 to rotate. The rotation of the rotating shaft 19 drives the two threaded segments 20 with opposite screw directions to rotate simultaneously, so that the threaded segments 20 drive the clamping plate 15 to rotate, and the two clamping plates 15 move closer together, thereby clamping the connected wire.

[0039] Example 2

[0040] Reference Figure 1 and Figure 4 An electrical junction box has an adjusting gear 10 fixed on the outside of a limiting post 6 and between a connecting plate 11 and a positioning annular groove 7. One end of the adjusting gear 10 is meshed with a displacement rack 12. The top of the displacement rack 12 is slidably connected to one of the positioning plates 8, thereby restricting the displacement rack 12 to only move horizontally by sliding between the displacement rack 12 and the positioning plate 8. At the same time, the bottom of the displacement rack 12 can also be supported by the top of the connecting plate 11. A limiting block 9 is fixed to the bottom of the positioning plate 8. The top of the displacement rack 12 is slidably connected to one of the positioning plates 8 by the limiting block 9, thereby restricting the displacement rack 12 from rotating when it moves horizontally by the limiting block 9.

[0041] A first threaded post 13 is rotatably connected to the inside of one side of the fixed box 1 at a position corresponding to the displacement rack 12. The outer side of one side of the first threaded post 13 is threadedly connected to the displacement rack 12, so that the rotation of the first threaded post 13 can drive the threaded displacement rack 12 to move. A second threaded post 14 is threadedly connected to the bottom end of the first threaded post 13 inside one side of the fixed box 1. The length of the second threaded post 14 is less than the length of the first threaded post 13. The outer side of one side of the second threaded post 14 is threadedly connected to the displacement rack 12, so that when the second threaded post 14 is inside the displacement rack 12, the rotation of the first threaded post 13 cannot drive the displacement rack 12 to move. At the same time, the second threaded post 14 can be disengaged from the threaded displacement rack 12 and the fixed box 1 by rotating the second threaded post 14.

[0042] The electrical junction box provided by this utility model is used as follows: When it is necessary to move the displacement rack 12, firstly, the second threaded post 14 is rotated, so that the rotation of the second threaded post 14 is connected to the fixed box 1 and the displacement rack 12 by the thread. The rotation of the second threaded post 14 is then disengaged from the displacement rack 12 and then from the fixed box 1. Then, the top of the displacement rack 12 is slidably connected to the limiting block 9, which restricts the displacement rack 12 from rotating with the first threaded post 13. Then, the first threaded post 13 is rotated, so that the first threaded post 13 drives the threaded displacement rack 12 to translate. The translation of the displacement rack 12 drives the meshing adjustment gear 10 to rotate, so that the rotation of the adjustment gear 10 drives the limiting post 6 to rotate. The limiting post 6 is height-limited by the two positioning plates 8. The rotation of the limiting post 6 drives the two clamping plates 15 to rotate through the connecting plate 11. The clamping and rotation of the clamping plates 15 are used to adjust the tightness of the wiring connected inside the fixed box 1, while reducing the loosening of the wiring.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it.
