Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, and in particular to a distribution box which is easy to assemble. Background Art

[0002] The distribution box is a device that integrates electrical components such as air switches, circuit breakers, and knife switches. It is widely used in residential buildings, schools, hospitals and other areas of daily life due to its unique functions. The main function is to distribute and control power to electrical equipment and provide short-circuit protection when the circuit is overloaded, short-circuited or leaking.

[0003] However, after the wires in the existing distribution box are placed for a long time, dust may accumulate on the wire heads, thereby affecting the metal contact with the electrical components and causing poor contact. To solve this problem, a common solution is to cut off the original exposed metal heads and cut off the insulating shells to expose the new metal heads and electrically connect them to the switches.

[0004] Although this can solve the problem of poor wire contact, the following problem still exists: in order to keep the wires neat and tidy, the wires in the distribution cabinet are usually clamped and fixed by a fixing clamp. However, after the new metal head is cut, the cable length is reduced, while the other end of the wire is still clamped and fixed, resulting in insufficient wire length extended from the clamping device, making it difficult to make electrical connections with electrical components. Utility Model Content

[0030] The following will be combined with 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 of 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.

[0031] like Figure 2 to Figure 9 As shown, a distribution box that is easy to assemble includes a box body 1. The box body 1 in this embodiment is a rectangular parallelepiped structure, a working chamber 11 is arranged in the box body 1, a box door 2 is rotatably connected to the box body 1, a number of heat dissipation structures are arranged on both sides of the box body 1, a number of mounting rails 41 are fixedly arranged at the bottom of the box body 1, and each mounting rail 41 is parallel to each other, a number of control switches 4 are fixedly arranged on each mounting rail 41 by screws, a first cable trough 51 and a second cable trough 52 are arranged in the working chamber 11, the first cable trough 51 is arranged at both ends of the mounting rail 41 and is perpendicular to the mounting rail 41, the second cable trough 52 is parallel to the mounting rail 41, and the second cable trough 52 is spaced apart from the mounting rail 41, and a dust cover 6 is clamped on the first cable trough 51 and the second cable trough 52. A number of storage structures are arranged in the second cable trough 52, which are used to facilitate the storage of cables by tightening the length of the cables.

[0032] The mounting groove 22 in this embodiment is arranged on the box door 2, and the visual window 21 is fixedly arranged in the mounting groove 22 by threaded connection, and the visual window 21 is made of glass material. Such a design allows the user to understand the situation inside the box body 1 without opening the window, thereby avoiding the risk of the user frequently opening the box door 2 and causing the electrical components inside the box body 1 to be lost.

[0033] In this embodiment, the cross-section of the first cable trough 51 is a "U" - shaped structure. A number of elastic hooks 511 are arranged on both sides of the first cable trough 51, and a clamping groove 61 is arranged at the bottom of the dust - proof cover 6. The elastic hooks 511 are clamped with the clamping groove 61. The first cable trough 51 and the second cable trough 52 have the same structure. The elastic hooks 511 can provide a certain pressure, ensuring the stability of the storage structure. Moreover, the design of the clamping groove 61 and the hooks can effectively prevent dust or moisture from entering the cable trough, effectively extending the service life of the cable.

[0034] The storage structure in this embodiment includes a housing 8. The housing 8 is a cylindrical structure. A control cavity 83 is arranged inside the housing 8. A top surface 82 is fixedly arranged at the top of the housing 8. A rotating member 9 is arranged inside the control cavity 83. The rotating member 9 is a cylindrical structure. A first storage hole 81 is arranged on the outer wall of the housing 8. The first storage hole 81 passes through the central axis of the housing 8. A second storage hole 91 is arranged on the rotating member 9. The second storage hole 91 passes through the central axis of the rotating member 9. The aperture of the first storage hole 81 is larger than that of the second storage hole 91. When the rotating member 9 rotates with the top surface 82 through threads, the height between the first storage hole 81 and the second storage hole 91 will be staggered. This can reduce the pressure on the cable caused by the staggering of the first storage hole 81, preventing cable damage. The central horizontal height of the first storage hole 81 is the same as that of the second storage hole 91. A threaded hole 821 is arranged on the top surface 82, which is thread - connected to the rotating member 9. In this embodiment, through the second storage hole 91 on the rotating member 9, by staggering the horizontal positions of the first storage hole 81 and the second storage hole 91 by the rotating member 9, the purpose of adjusting the length of the cable is achieved. By rotating the rotating member 9, the cable can be tightened or loosened to meet different length requirements.

[0035] In this embodiment, a mounting plate 84 is fixedly arranged at the bottom of the housing 8. A mounting hole 512 is arranged at the bottom of the second cable trough 52. The mounting plate 84 and the mounting hole 512 are fixedly connected by threads to ensure the fixed installation of the storage structure, preventing it from being loose or displaced. A rotating groove 92 is arranged at the top of the rotating member 9. The cross - section of the rotating groove 92 is a "cross" - shaped structure, which enables users to adjust and rotate the rotating member 9 with a screwdriver. This is not only convenient for operation but also can achieve self - locking when rotated to the appropriate angle, avoiding sliding or loosening during the storage process and improving the stability of the overall structure.

[0036] The raised frame 7 in this embodiment is arranged at the bottom of the box body 1. The cross-section of the raised frame 7 is a rectangular structure. The reinforcing ribs 73 are arranged inside the raised frame 7 to improve the overall load-bearing capacity and enhance the stability of the box body 1. The limit frame 71 is arranged at the upper end of the raised frame 7 to limit the movement range of the wire body to prevent the position of the box body 1 from shifting or sliding. The supporting legs 72 are arranged at the bottom of the raised frame 7. There are four supporting legs 72, which are fixed at the four corner ends of the raised frame 7 to reduce wear on the ground. This design increases the distance from the ground and ensures that water will not penetrate into the box body 1 when water accumulates on the ground.

[0037] The heat dissipation structure in this embodiment includes a heat dissipation hole 3, and a heat dissipation fan 31 is arranged on the inner wall of the working chamber 11 near the heat dissipation hole 3. The heat dissipation fan 31 is connected and fixed to the working chamber 11 by bolts to ensure that the heat dissipation fan 31 is stably installed, not only not prone to loosening or displacement, but also convenient for users to repair and replace. If the heat dissipation fan 31 needs to be cleaned, it can be removed by simply loosening the bolts. The heat dissipation hole 3 in this embodiment allows the heat inside the working chamber 11 to be quickly dissipated, and the heat dissipation fan can accelerate the air flow, making the heat dissipation effect more efficient and uniform.

[0038] The working process of this embodiment: First, pass the cable through the first storage hole 81 and the second storage hole 91 at the same time, and then electrically connect it to the control switch 4. After the connection is completed, the cable needs to be stored: turn the rotating slot 92 with a screwdriver to make the rotating member 9 drive the cable to rotate. At this time, the length of the cable is shortened due to being wound in the rotating member 9, so that the cable is placed more tightly and neatly in the second cable slot 52; when the length of the cable is reduced due to cutting, the rotating slot 92 is rotated in the opposite direction by a screwdriver, so that the rotating member 9 drives the cable to rotate until the center of the first storage hole 81 and the second storage hole 91 overlap again. After readjusting the length of the cable, turn the rotating slot 92 again with a screwdriver to complete the final storage operation of the cable. At this time, the cable wound in the rotating member 9 is extended, and the length of the cable is lengthened.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
