[0030] The power distribution control box of the utility model will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the utility model is shown. It should be understood that the utility model described herein can be modified by those skilled in the art, while still achieving the advantageous effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the utility model.

[0031] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0032] like Figures 1 to 4 As shown, an embodiment of the utility model provides a power distribution control box, including a box body 1, a cover plate 2, a movable slot 3 and a connecting piece 4.

[0033] The cover plate 2 is hinged on one side of the box body 1 and has a cavity 21 to form a space for wrapping the connector 4 to prevent the setting of the connector 4 from interfering with the fit between the cover plate 2 and the box body 1 .

[0034] The upper surface of the box body 1 has a protrusion 11, and the protrusion 11 can be placed in the cavity 21, that is, when the cover plate 2 is deflected to fit with the box body 1, the protrusion 11 can be received in the cavity 21 to avoid interference caused by the existence of the protrusion 11.

[0035] In addition, the movable groove 3 is arranged on the outer wall of the protrusion 11 and includes a sliding groove 31 and an abutting groove 32 which are connected to each other.

[0036] One end of the connecting member 4 is hinged to the inner wall of the cavity 21 , and the other end is movably installed in the movable groove 3 .

[0037] When one end of the connecting member 4 is placed in the slide slot 31, the cover plate 2 can be deflected in a direction close to or away from the box body 1. That is, when the connecting member 4 moves in the slide slot 31, it can deflect itself and pull the cover plate 2 to deflect in a direction close to or away from the box body 1, so as to complete the opening or closing of the box body 1.

[0038] In addition, when one end of the connecting member 4 is placed inside the abutting groove 32, an angle is formed between the cover plate 2 and the box body 1, that is, the box body 1 is in an open state, which is convenient for maintenance personnel to perform maintenance.

[0039] At this time, the inner wall of the abutment groove 32 hinders the movement of the connecting member 4, so that the connecting member 4 cannot move arbitrarily, and then a triangular support system is formed around the cover plate 2, the connecting member 4 and the box body 1 to resist interference from external factors and prevent the cover plate 2 from deflecting toward one side of the box body 1 due to sudden forces (such as wind force or external collision force on the cover plate 2), causing hand injuries to the maintenance personnel.

[0040] The device is provided with a movable groove 3 including a slide groove 31 and an abutment groove 32, and a connecting member 4 which is hinged to the cover plate 2 at one end and connected to the movable groove 3 at the other end, and when the connecting member 4 is placed in the abutment groove 32, an angle can be formed between the cover plate 2 and the box body 1, so as to facilitate maintenance personnel to carry out maintenance, and because the inner wall of the abutment groove 32 can hinder the movement of the connecting member 4, the cover plate 2 cannot deflect accordingly, that is, a stable triangular support system can be formed between the connecting member 4, the cover plate 2 and the box body 1 to resist interference from external factors. Therefore, it can effectively avoid the cover plate 2 from quickly deflecting in the direction close to the box body 1 due to the influence of sudden external force during the maintenance process, thereby causing hand injuries to the maintenance personnel, thereby improving the safety factor.

[0041] It should be particularly noted that the bottom wall of the abutment groove 32 is located below the bottom wall of the slide groove 31, so that the connector 4 can overlap the bottom wall of the abutment groove 32 when it is not subjected to external force. That is, by arranging the bottom wall of the abutment groove 32 below the slide groove 31, it is convenient for the end of the connector 4 connected to the movable groove 3 to fall into the abutment groove 32 under the action of gravity and the downward traction force formed on the connector 4 when the cover plate 2 deflects, so as to quickly limit the connector 4, and accordingly, it can also prevent the cover plate 2 from deflecting in the direction close to the box body 1, so as to achieve the purpose of protecting the safety of maintenance personnel.

[0042] It should be noted that when the cover 2 needs to be moved in a direction close to the box body 1 to close the box body 1, the connector 4 can be manually moved so that the connector 4 is placed in the slide groove 31, and then the cover 2 is pushed to deflect, so that the cover 2 can be quickly fitted with the box body 1.

[0043] In this embodiment, the movable groove 3 can be configured as an L-shaped structure to form the sliding groove 31 and the abutting groove 32 that are interconnected.

[0044] In a further embodiment, the power distribution control box further includes an operation panel 5, and the operation panel 5 is embedded in the box body 1 for daily maintenance and debugging.

[0045] In addition, a handle 51 is provided on the operation panel 5 to facilitate disassembly of the operation panel 5 .

[0046] In other embodiments, in order to facilitate the installation of the operation panel 5 , a panel fixing bracket 6 is further provided on the inner wall of the box body 1 for carrying the operation panel 5 .

[0047] The panel fixing bracket 6 and the operation panel 5 are connected via fastening screws 7 .

[0048] It should be noted that, in order to improve the connection effect between the panel fixing bracket 6 and the operation panel 5 , the fastening screws 7 are arranged at the edge corners of the operation panel 5 .

[0049] In other embodiments, the outer wall of the box body 1 is provided with a lock 8 for limiting the cover plate 2.

[0050] In a further embodiment, in order to enhance the protection effect on the circuit components in the box body 1 , a sealing rib 9 is provided around the upper surface of the box body 1 .

[0051] It should be noted that when the cover plate 2 is deflected to fit with the box body 1, the sealing rib 9 fits with the inner wall of the cavity 21 to form a sealed chamber with the box body 1, which can effectively protect the circuit components and correspondingly extend the service life of the circuit components.

[0052] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
