[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] See also Figures 1 to 8, is a distribution box that is easy to repair as the best embodiment of the utility model, comprising:

[0042] The box body 10 includes a cabinet body 11 and a cabinet door 12 for closing an opening of the cabinet body 11;

[0043] A reflective mark 20 is provided on the outer side wall of the cabinet door 12;

[0044] The lighting device 30 is disposed on two opposite side walls of the cabinet 11 and includes a base 40 and a lamp body 50 rotatably connected to one end of the base 40;

[0045] The battery module 60 is arranged in the cabinet 11, and its input end and output end are electrically connected to the external source circuit and the lamp body 50 respectively, and is used to store the electric energy input by the external source circuit and provide the lighting electricity of the lamp body 50. In this embodiment, the battery module 60 is a lithium battery capable of storing energy, and its external external source circuit is the lead-out line in the distribution box. When the distribution box is working normally, the electric energy is input to the battery module 60 for storage, and when the distribution box stops working unexpectedly, the electric energy can be output to the lighting device 30 in the turned-on state;

[0046] Among them, combined Figure 8 A normally open connection structure 70 is provided on the connection circuit between the output end of the battery module 60 and the lamp body 50 , and the normally open connection structure 70 is closed when the lamp body 50 rotates in a direction away from the base 40 .

[0047] Specifically, Figure 5As shown, a mounting space 54 for wiring and installing lighting modules such as an LED light source 57 is provided in the lamp body 50. The normally open connection structure 70 includes a first contact 71 electrically connected to the battery module 60, a second contact 72 electrically connected to the lamp body 50, a contact sheet 73 and a separation sheet 74. The first contact 71 and the second contact 72 are respectively arranged at the bottom of the mounting space 54, and a through groove 55 penetrating to the external environment is provided at a position between the first contact 71 and the second contact 72 in the mounting space 54. The separation sheet 74 is arranged at a position on the base 40 opposite to the through groove 55 and its extension height is greater than the thickness of the through groove 55. One end of the contact sheet 73 is connected to the edge of the second contact 72 and the other end extends horizontally to the position of the first contact 71 to form an active end 731 that is movably overlapped with the first contact 71. When the lamp body 50 contacts the base 40, the separation sheet 73 is provided. The sheet 74 penetrates into the installation space 54 along the through groove 55 and pushes the movable end 731 of the contact sheet 73 away from the first contact 71. Therefore, when the lamp body 50 and the base 40 are in a non-use state, that is, when they are in contact with each other, the separating sheet 74 penetrates into the installation space 54 and pushes the end of the contact sheet 73 overlapping with the first contact 71 away from the first contact 71, so that the battery module 60 and the LED light source 57 in the lamp body 50 are in a normally open connection state, and the circuit is not closed; when the distribution box is in a faulty state, the maintenance personnel grope for the lamp body 50 and turn it up to adjust it to the required position and angle. When the lamp body 50 rotates away from the base 40, the separating sheet 74 leaves the installation space 54, and the contact sheet 73 overlaps with the first contact 71 again under the action of its own rebound force, the circuit is closed again, and the LED light source 57 obtains the function of the battery module 60.

[0048] Preferably, Figure 5 As shown, a hemispherical protrusion 732 is integrally formed on the lower end surface of the movable end 731 of the contact piece 73 .

[0049] Preferably, Figure 5 As shown, the separation sheet 74 is a thin insulating sheet and a curved transition end (not shown in the figure) is formed on the top thereof, so as to facilitate the separation and contact between the contact sheet 73 and the first contact point 71 .

[0050] Preferably, Figure 3 , 4As shown in FIGS. 6 and 7 , the lamp body 50 includes a rotating section 51, an extension section 52 and a working section 53 arranged in a colinear manner. One end of the rotating section 51 is rotatably connected to the base 40 through a rotating shaft, and the other end of the rotating section 51 extends an adjusting shaft 56 vertically outward. The extension section 52 is slidably inserted into the adjusting shaft 56 and is provided with a locking structure 80 for limiting the relative position of the extension section 52 and the adjusting shaft 56. The working section 53 is rotatably connected to a side of the extension section 52 away from the rotating section 51. The adjusting shaft 56 is provided with a plurality of annular limiting grooves 561 at intervals along its axial direction. The extension section 52 is provided with a mounting groove 521 that slidably cooperates with the adjusting shaft 56. The outer wall of the extension section 52 is provided with an adjustment groove 522 which is vertically connected to the installation groove 521. The locking structure 80 includes a locking member 81 which is slidably arranged in the adjustment groove 522 and a reset spring 82 which is arranged between the locking member 81 and the inner bottom of the adjustment groove 522. A clearance groove 83 for the adjustment shaft 56 to pass through is opened in the middle of the locking member 81. A limiting edge 84 which can be clamped with the limiting groove 561 is formed on the side of the clearance groove 83 close to the reset spring 82. The spacing between the limiting edge 84 and the other side of the clearance groove 83 is greater than twice the outer diameter of the adjustment shaft 56. A side of the locking member 81 close to the inner bottom of the adjustment groove 522 is formed for accommodating the reset spring 8 2, a positioning column 821 is convexly provided at the bottom of the adjusting groove 522, one end of the return spring 82 is inserted into the positioning column 821 and the other end thereof is movably inserted into the receiving groove 811, and limiting grooves 85 are symmetrically provided on both sides of the adjusting groove 522, and limiting edges 86 that are limitedly matched with the limiting grooves 85 are symmetrically formed on both sides of the locking member 81. When the locking member 81 is in a non-pressed state, it is pushed by the return spring 82 to a position close to the outer surface of the extension section 52. At this time, the limiting edge 84 on one side of the giving groove 83 is tightly matched with the limiting slot at the corresponding position, and the relative position of the extension section 52 and the adjusting shaft 56 is fixed. When it is necessary to adjust the above When the locking member 81 is in the correct position, it is only necessary to press the locking member 81 so that the locking member 81 presses the reset spring 82. At this time, the positioning groove 83 moves to the side close to the reset spring 82, and the limiting edge 84 is away from the limiting slot. The adjustment shaft 56 is in a slidable non-locking state, and the position of the extension section 52 is adjusted. After it is adjusted to the appropriate position, the locking member 81 is released, and the above locking process is repeated, so that the limiting edge 84 is re-engaged in the limiting slot in the new position, and the extension section 52 is locked and fixed again, thereby realizing the position adjustment of the working section 53; in addition, the cooperation between the limiting edge 86 and the limiting slot 85 ensures that the locking member 81 is always in the adjustment slot 522.

[0051] Preferably, Figure 4As shown in the figure, the base 40 includes a strip-shaped connecting piece 41 and a number of "U"-shaped buckle pieces 42 arranged in sequence on the connecting piece 41. A buckle space (not marked in the figure) for the lamp body 50 to be embedded is formed at the upper end of the buckle piece 42. An installation hole 43 is provided at the bottom inside the buckle space, and a magnetic sheet 44 is provided at the bottom inside the buckle space. A magnetic attracting part (not marked in the figure) that can be magnetically attracted to the magnetic sheet 44 is embedded at a position on the outer shell of the lamp body 50 opposite to the magnetic sheet 44. The magnetic connection method is adopted between the lamp body 50 and the base 40, which not only facilitates the quick disassembly and reinstallation of the lamp, but also enhances the overall stability and simplifies the installation and maintenance process.

[0052] Specifically, as Figure 2 shown in the figure, there are two lighting devices 30 in total in the cabinet body 11, and arrow-shaped reflective signs 20 are pasted at the position of the opening of the cabinet body 11 corresponding to each lighting device 30, so as to provide a prompt for the maintenance personnel when they initially open the cabinet door 12, enabling them to quickly locate the position of the lighting device 30 and facilitating quick maintenance.

[0053] The beneficial effects of the present utility model are as follows:

[0054] The reflective sign 20 provided on the cabinet door 12 can quickly guide the maintenance personnel to quickly locate the distribution box in the case of no lighting such as power failure, and the built-in battery module 60 and lighting device 30 ensure that sufficient lighting can still be provided in the case of power failure or emergency, thus ensuring the smooth progress of the maintenance work and greatly improving the safety and maintenance efficiency of the equipment.

[0055] The uniquely designed normally open connection structure 70 further optimizes the power management. When the lamp body 50 turns to a specific position, this structure ensures that the lighting device 30 is quickly powered on, and together with the daily power supply of the battery module 60 by the external circuit, it enables the maintenance personnel to use the lighting device 30 for lighting even in the case of no external power supply, effectively shortening the maintenance time.

[0056] The collinear arrangement of the rotating section 51, the extending section 52 and the working section 53 included in the lamp body 50 provides multi-angle and multi-direction lighting for the maintenance personnel, ensuring the convenience of the maintenance work.

[0057] The flexible adjustment shaft 56 and the fine adjustment mechanism included in the structure of the lamp body 50, such as the locking structure 80, the limit groove 561 and the return spring 82, etc., allow the lamp body 50 to be positioned and the brightness to be adjusted to the optimal working angle, providing more precise lighting control.

[0058] In summary, the present utility model greatly improves the maintenance conditions of the distribution box and provides a more convenient and safe operation environment for the maintenance work.

[0059] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
