[0003] There are many types of wire boxes, which are used in construction, industry and home. Among them is a lintel box, which is suitable for passing wires through walls or beams. The lintel box can protect the wires from friction and wear of walls or beams, thereby extending the service life of the wires.

[0004] In actual use, in order to avoid opening a hole that is too large for the beam column, the existing lintel box generally opens a hole with a larger space on the beam column, and the lintel box is provided with a threading hole with a larger aperture corresponding to the hole, so that multiple lines can pass through, and the other side of the lintel box is provided with branch holes matching the number of lines, so that the multiple lines are separated, and when the wires are inserted from the threading holes into the branch holes, except for the branch holes located in the middle, the wires in other branch holes are bent in the lintel box, and the bending causes the wires to have a large resistance to movement inside the lintel box, making the wire threading operation difficult and prone to wear and tear. Based on this, a lintel box for erecting a power transmission project is provided. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 3 In an embodiment of the utility model, a wire box for erecting a power transmission project includes a wire box 1 composed of a box body 101, a wire threading hole 102, and a branching tube 103. The wire threading hole 102 is formed on one side of the outer wall of the box body 101 and is connected to the inner cavity of the box body 101. A branch hole that runs through both sides of the box body 101 is opened on the other side of the box body 101. The branching tube 103 is installed on the inner side of the branch hole. A drag reduction guide component 2 is provided on the inner side of the box body 101. The drag reduction guide component 2 is used to provide a guiding operation for the wire 3 between the wire threading hole 102 and the branching tube 103;

[0027] The drag reduction guide assembly 2 includes a rolling guide unit and a limiting unit. The rolling guide unit is used to guide and limit the moving track of the wire 3, and at the same time, it is used to reduce the friction force of the wire 3 when it moves by rotating itself. The limiting unit is used to limit the upper part of the wire 3 located in the middle of the rolling guide unit to prevent the wire 3 from being separated from the rolling guide unit.

[0028] The rolling guide unit includes a fixed column 201, a rotating chassis 202, and a guide column 203. The fixed column 201 is threadedly fixed to the bottom of the inner side of the box body 101, the rotating chassis 202 is rotatably connected to the top of the fixed column 201, and the guide column 203 is fixed to the top of the rotating chassis 202. The fixed columns 201 are symmetrically distributed in pairs, and the sides of the two rotating chassis 202 on the two symmetrically distributed fixed columns 201 are tangent to each other. The two rotating chassis 202 are used to provide support for the wire 3. The wire 3 passes through the middle of the two guide columns 203. The two guide columns 203 are used to provide a limit guide for the movement of the wire 3. At the same time, the rotation of the guide column 203 is used to reduce the friction force when the wire 3 moves;

[0029] There are multiple drag reduction guide assemblies 2, and the multiple drag reduction guide assemblies 2 are divided into multiple groups, and the distribution trajectories of the multiple drag reduction guide assemblies 2 in each group of drag reduction guide assemblies 2 correspond to the trajectories of the wires 3 between each branch pipe 103 and the threading hole 102.

[0030] In this embodiment: when using this wire passing box 1, when the wire 3 passes through the wire passing hole 102 and enters the inner side of the box body 101, the wire 3 can be inserted into the middle of the corresponding drag reduction guide component 2 according to the position of the branch pipe 103 that the wire 3 is to enter, and the wire 3 will enter the branch pipe 103 along the middle of the guide column 203 in the multiple groups of drag reduction guide components 2. The distribution tracks of the multiple groups of drag reduction guide components 2 will guide the moving track of the wire 3, so that the moving track of the wire 3 tends to be smoother, so as to avoid the wire being stuck due to excessive bending angle;

[0031] In addition, when the wire 3 is pulled and moved, the guide column 203 will also rotate synchronously, so that the friction resistance of the wire 3 can be reduced, so that the wire 3 can pass through the inside of the wire box 1 more smoothly;

[0032] Through the coordination of the above multiple parts, it is possible to effectively avoid excessive friction losses of the wires 3 in the wire box 1, and at the same time, multiple wires 3 are separated from each other inside the wire box 1, so that the laying of the wires 3 is neater, and the resistance of the wires 3 when passing through the wire box 1 is smaller, which can further improve the laying efficiency of the wires 3.

[0033] Please refer to Figures 1 to 3 , the limiting unit includes a rubber limiting wheel 204;

[0034] The rubber limiting wheel 204 is sleeved on the outer bottom of the guide column 203, the outer diameter of the rubber limiting wheel 204 is smaller than the outer diameter of the rotating chassis 202, and the gap width between two symmetrically distributed rubber limiting wheels 204 is smaller than the outer diameter of the wire 3;

[0035] The rubber limiting wheel 204 has a certain elasticity for allowing the power line 3 to squeeze through the gap between the two rubber limiting wheels 204 and enter between the two guide pillars 203 . After the rubber limiting wheel 204 is reset, it is used to limit the space above the wire 3 .

[0036] In this embodiment, the wire 3 is squeezed downward from the middle of the two rubber limiting wheels 204, and the rubber limiting wheels 204 are forced to shrink and the distance between them becomes larger, so that the wire 3 can smoothly pass through the middle of the two rubber limiting wheels 204. When the wire 3 enters the middle of the two guide posts 203, the rubber limiting wheels 204 lose the squeezing and reset under the action of their own elastic force.

[0037] The rubber limiting wheel 204 limits the space above the wire 3, so that when the wire 3 is pulled, the wire 3 can be kept between the two guide pillars 203, so that the moving track of the wire 3 remains stable.

[0038] Please refer to Figures 1 to 3 A trumpet expansion opening 104 is integrally formed on the inner side of the box body 101 at a position aligned with the threading hole 102 , and the trumpet expansion opening 104 gradually increases in diameter toward the direction of the branch pipe 103 .

[0039] In this embodiment, the trumpet expansion opening 104 is provided to adapt to the trajectory of the curved wire 3 , thereby avoiding scratches between the curved wire 3 and the edge of the threading hole 102 , and effectively reducing the wear of the wire 3 .

[0040] Please refer to Figures 1 to 3 The box body 101, the threading hole 102, the branch hole, and the horn expansion opening 104 are integrally formed by an injection molding process, and the fixing column 201 is connected and fixed to the box body 101 by ultrasonic welding.

[0041] In this embodiment, this structure reduces the number of production and processing steps of the entire wire box 1, simplifies the process, and facilitates production promotion.

[0042] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
