All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1 to 3 shown, a distribution box for construction engineering construction provided by the present utility model includes a box body 1, a heat dissipation slot 2, a mounting bracket 3 and a wire threading hole 4. The heat dissipation slot 2 is opened on the right side of the box body 1. The mounting bracket 3 is fixedly connected to the rear side of the inner wall of the box body 1.

A driving assembly 8 is fixedly connected to the right side of the bottom of the inner wall of the box body 1. Locking assemblies 9 are fixedly connected to both sides of the inner wall of the U-shaped frame 5.

[0023] Referring to Figure 1 and Figure 2 , the driving assembly 8 includes a driving motor 81. The driving motor 81 is fixedly connected to the right side of the bottom of the inner wall of the box body 1. The output end of the driving motor 81 is fixedly connected to a first helical gear 82. The left side of the first helical gear 82 is meshed with a second helical gear 83. The second helical gear 83 is fixedly connected to the right side of the wire take-up roller 7.

[0024] As a technical optimization scheme of the present utility model, by setting the driving assembly 8, it can effectively make the driving motor 81 drive the first helical gear 82 to rotate. The first helical gear 82 drives the second helical gear 83 to rotate. The second helical gear 83 drives the wire take-up roller 7 to wind up the redundant wires, avoiding the shaking of the redundant wires and causing the connection points to become loose, thereby improving the stability after the wires are connected inside the distribution box.

[0025] Referring to Figure 1 and Figure 2 , the locking assembly 9 includes a mounting plate 91. The mounting plate 91 is fixedly connected to both sides of the inner wall of the U-shaped frame 5. A locking rod 92 is movably connected to the inner wall of the mounting plate 91. Locking holes 93 are opened on both sides of the surface of the wire take-up roller 7. The number of the locking holes 93 is set to be several groups and is distributed at equal intervals in a ring shape. The bottom of the locking rod 92 is movably connected to the inner wall of the locking hole 93.

[0026] As a technical optimization solution of the present utility model, by setting the locking assembly 9, after the wire winding roller 7 finishes winding the wire, the user inserts the locking rod 92 into the inner wall of the mounting plate 91 and moves the locking rod 92 to the inner wall of the locking hole 93, so as to lock the wire winding roller 7, prevent the wire from being pulled by external force and causing the wire winding roller 7 to rotate, and enhance the stability after the wire is wound.

[0027] Reference Figure 1 and Figure 2 , a chute 10 is provided on the surface of the wire winding roller 7, and a partition plate 11 is movably connected to the inner wall of the chute 10.

[0028] As a technical optimization solution of the present utility model, by setting the chute 10 and the partition plate 11, when winding the wire, the partition plate 11 slides on the inner wall of the chute 10, so as to block and classify different types of wires, prevent the wires of different types from being wound when being wound, and facilitate the user's later maintenance.

[0029] Reference Figure 1 and Figure 2 , both sides of the partition plate 11 are fixedly connected with protective pads 12, and the protective pads 12 are made of rubber.

[0030] As a technical optimization solution of the present utility model, by setting the protective pads 12, the partition plate 11 can effectively fix the protective pads 12, and the rubber protective pads 12 can protect the wire, avoid friction between the wire and the partition plate 11 and cause damage, and improve the safety when the wire is wound.

[0031] Reference Figure 1 and Figure 3 , a movable frame 13 is provided at the bottom of the wire threading hole 4, and auxiliary wheels 14 are movably connected to both sides of the inner wall of the movable frame through bearings.

[0032] As a technical optimization solution of the present utility model, by setting the movable frame 13 and the auxiliary wheels 14, the wire can effectively enter the wire threading hole 4 through the inside of the auxiliary wheels 14, and the wire contacts the surface of the auxiliary wheels 14. By pulling the wire, the auxiliary wheels 14 can be driven to rotate, so that the auxiliary wheels 14 can improve the winding efficiency of the wire.

[0033] Reference Figure 1 and Figure 3 , the bottom of the movable frame 13 is fixedly connected with a mounting ring 15, and a brush 16 is fixedly connected to the inner wall of the mounting ring 15. The number of the brushes 16 is set to several groups and is evenly distributed in a ring at equal intervals.

[0034] As a technical optimization solution of the present utility model, by providing the mounting ring 15 and the brush 16, the mounting ring 15 can effectively fix the brush 16. When the wire moves upward, the surface of the wire can be cleaned by the brush 16 to prevent impurities and dust on the wire surface from entering the interior of the box body 1.

[0035] The working principle and usage process of the present utility model are as follows: When in use, first pass the wire through the wire passing hole 4 into the interior of the box body 1, and use the mounting bracket 3 and bolts to fix the components inside the box body 1. Then the user starts the driving motor 81 to drive the first helical gear 82 to rotate. The first helical gear 82 drives the second helical gear 83 to rotate, and the second helical gear 83 drives the wire take-up roller 7 to wind up the excess wire, preventing the excess wire from shaking and causing the connection to become loose, thereby achieving the effect of preventing loosening at the wire connection. After the excess wire is wound up, the wire can be connected to the components. During the process of winding up the wire, the wire passes through the interior of the movable frame 13, enters the wire passing hole 4 through the inner side of the auxiliary wheel 14, and contacts the surface of the auxiliary wheel 14. By pulling the wire, the auxiliary wheel 14 can be driven to rotate, enabling the auxiliary wheel 14 to improve the winding efficiency of the wire. During the movement of the wire, the surface of the wire is cleaned by the brush 16. Then, by pulling the partition plate 11 on the inner wall of the sliding groove 10, and the partition plate 11 slides on the inner wall of the sliding groove 10, different types of wires can be blocked and classified to prevent entanglement when different types of wires are wound up. After the excess wire is wound up, the user inserts the locking rod 92 into the inner wall of the mounting plate 91 and moves the locking rod 92 into the inner wall of the locking hole 93, thereby locking the wire take-up roller 7 to prevent the wire take-up roller 7 from rotating due to external pulling force on the wire, enhancing the stability after the wire is wound up.

[0036] In summary, for this distribution box for construction engineering construction, by providing the U-shaped frame 5, the wire take-up roller 7, the driving assembly 8 and the locking assembly 9, the driving assembly 8 can effectively drive the wire take-up roller 7 to rotate on the inner wall of the U-shaped frame 5. The wire take-up roller 7 can wind up the excess wire after connection, preventing the excess wire from shaking and causing the connection to become loose, solving the problem that the device lacks an anti-loosening structure. After the components inside the distribution box are connected to the wire, the wire cannot be wound up and fixed, and the wire will be subjected to various external forces, causing the connection to become loose, thereby affecting the normal operation of the circuit.
