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

[0002] The distribution box is a key mechanism for modern power transmission. It is used to assemble electrical appliances for power distribution, so that electric energy can be distributed to lower-level distribution equipment in different locations, ensuring the reasonable distribution and output of power between power facilities.

[0003] There are many electrical components installed in the distribution box. After long-term use, these electrical components will become old and aged, affecting the normal use of the distribution box. Therefore, the electrician will inspect the distribution box and replace these electrical components.

[0004] At present, when inspecting and repairing electrical components in the distribution box, different electrical components are installed using different screw specifications. When inspecting and repairing, general electricians will randomly place the screws used by the disassembled different electrical components on the ground, which will not only cause the screws to be lost, but also when installing different electrical components later, it is necessary to find the corresponding screws, which greatly reduces the convenience of finding the corresponding screws when disassembling, replacing and repairing old and aging electrical components.

[0005] In addition, the three main power lines of the existing distribution box generally pass through the top of the box and are then connected to the external main power supply to power the electrical components inside the distribution box. However, the three main power lines rub against the wire entry holes on the metal box, which will cause wear and tear on the outer wall of the main power line over a long period of time.

[0006] The above problems are widespread and urgently need to be improved. Utility Model Content

DETAILED DESCRIPTION

[0023] 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.

[0024] Example 1

[0025] See also Figures 1 to 4 The diagram shows a distribution box that is easy to maintain, including a box body 1, a box cover 2 is rotatably provided on the box body 1, a maintenance storage box 3 is provided on the box cover 2, and a main power line 8 is inserted at the top of the box body 1. The relevant structures in the claims of this new model are all component structures of the distribution box, which are prior art. Some existing structures are not drawn and marked, and there is no need to repeat them.

[0026] A storage chamber 31 is provided in the maintenance storage box 3, and a first partition 4 and a second partition 5 are provided in the storage chamber 31. The upper end of the storage chamber 31 is open, which improves the convenience of finding corresponding screws when disassembling, replacing and repairing old and aged electrical components.

[0027] There are six first partitions 4 arranged in a transverse arrangement, and the second partition 5 is arranged in the central part of the storage cavity 31, so as to divide the storage cavity 31 into a plurality of small compartments, thereby classifying and storing the disassembled screws of different specifications for convenient retrieval later.

[0028] The outer walls of the first partition 4 and the second partition 5 and the inner wall of the storage chamber 31 are provided with an anti-wear layer 32. The anti-wear layer 32 is made of nylon layer and has high wear resistance and puncture resistance, which prevents the screws from scratching the outer walls of the first partition 4 and the second partition 5 and the inner wall of the storage chamber 31.

[0029] An inner screw hole 6 is provided at the top of the box body 1, and an inlet sheath 7 is provided at the top of the box body 1. An outer wall of the inlet sheath 7 is provided with an outer thread 74, and the outer thread 74 is threadedly connected to the inner screw hole 6. An elastic sleeve 71 is provided in the inner cavity of the inlet sheath 7, and the main power cord 8 is extruded and inserted in the elastic sleeve 71. The elastic sleeve 71 is made of NBR nitrile rubber, which has high elasticity, wear resistance, durability and corrosion resistance, thereby realizing protection for the main power cord 8 passing through the elastic sleeve 71.

[0030] An anti-slip ring 72 is provided at one end of the cable inlet sheath 7 facing the outer wall of the box body 1. The anti-slip ring 72 is made of damping silicone material, and its lower end surface has an anti-slip grid pattern. When the cable inlet sheath 7 is threadedly locked into the internal screw hole 6, the cable inlet sheath 7 will squeeze the anti-slip ring 72, and combined with the damping friction effect, the installation anti-rotation stability of the cable inlet sheath 7 is improved.

[0031] The incoming wire sheath 7 is provided with inner grooves 73, and there are eight inner grooves 73 arranged in a circle. When installing the incoming wire sheath 7, fingers can be inserted into the inner grooves 73 and rotated clockwise. The incoming wire sheath 7 can be installed on the inner screw hole 6 without tools, which is very convenient.

[0032] When used in this embodiment: after long-term use, the electrical components installed in the box body 1 will become old and aged, affecting the normal use of the box body 1. Therefore, the electrician will inspect and disassemble and replace the electrical components. After removing these old and aged electrical components, the disassembled screws of different corresponding specifications can be conveniently placed in each storage cavity 31 of the maintenance storage box 3. When installing new electrical components at a later time, the screws of corresponding specifications can be conveniently found and taken out from the storage cavity 31, and then the corresponding electrical components can be installed in the box body 1. The screws removed during the maintenance process can be conveniently classified and stored, which improves the convenience of finding corresponding screws when disassembling, replacing and repairing old and aged electrical components.

[0033] In addition, taking a main power cord 8 as an example, hold an incoming line sheath 7 and rotate it clockwise, and lock it with the internal screw hole 6 through the external thread 74, and then pass the main power cord 8 through the inner cavity of the elastic sleeve 71 into the box body 1, so that the main power cord 8 can be connected to the main air switch later, and the outer wall of the main power cord 8 inserted into the box body 1 can be elastically and stably protected by the sleeve, so as to avoid the main power cord 8 and the metal box body 1. The friction between the incoming line hole and the main power cord 8 causes the outer wall of the main power cord 8 to be worn.
