Embodiment 1

[0025] In this embodiment, in order to facilitate the movement of the end cover, preferably, a slot 116 is provided on the lower end surface of the mounting plate 108, and a slot 116 is provided on the upper end surface of the housing 101 at the same position as the slot 116. The corresponding positioning groove 117 is provided with two through holes communicating with the card slot 116 on the mounting plate 108, and an armrest 118 is provided on the mounting plate 108, and the two ends of the armrest 118 Bending to the same side and penetrating through the corresponding through holes to make it a U-shaped structure. The pressing rod 119 connects the two ends of the opening side of the armrest, and enables the pressing rod to be embedded in the positioning slot, and the pressing rod 119 can be inserted into the locking groove 116 inside.

[0026] When the mounting plate fits on the upper surface of the shell, press down on the armrest so that the pressing rod on the armrest is...

Embodiment 2

[0028] In order to relatively fix the bottom plate on the inside of the stepped groove and keep the end cover stable, in this embodiment, preferably, a sunken groove 125 is provided on the inner end surface of the stepped groove 110, and the length direction of the sunken groove is parallel to the rotation axis. In the axial direction of the sinker, the sinker opens towards the side of the bottom plate, and two rubber pads 126 are arranged on the opening side of the sinker 125, and the rubber pads are respectively symmetrically arranged on the two end faces of the sinker opening to form a strip structure. Two flanges 127 are provided at the end of the bottom plate 109 away from the end cover 106 , and the flanges 127 can be clamped inside the sinker groove 125 .

[0029] When the end cover is attached to the shell, the flange on the bottom plate is clamped on the inside of the sinking groove, and the flange cannot be moved relatively by using the rubber pad. At this time, the b...

Embodiment 3

[0031] In this embodiment, in order to conveniently rotate the end cover after the boss moves out of the through groove, so that the operation panel is exposed, preferably, a torsion spring 120 is provided on the rotating shaft 111, and the torsion spring has two sides. The ends are respectively fixedly connected to the rotating shaft, the middle part of the torsion spring 120 abuts against the bottom plate 109, and the torsion spring 120 is in the maximum torsion angle state when the boss 107 is embedded in the inside of the through groove. . When the boss is moved out of the through groove, the mounting plate is separated from the upper end surface of the housing. At this time, under the elastic force of the torsion spring, the end cover rotates relatively, so that the end cover quickly moves to the outside. At this time, it can be conveniently used. The through slot is opened, and the operation panel can be seen conveniently and intuitively.

[0032] Under the action of the ...

Abstract

The present invention discloses a mobile maintenance power source box for a power grid. The mobile maintenance power source box comprises a shell and a charging box body arranged in the shell; two end surfaces of the charging box body, which face each other, are respectively provided with operation panels; one side of the shell is provided with a telescopic pull rod; two through slots are formed in the shell; the through slots are respectively corresponding to the operation panels; the inner sides of the through slots are provided with baffles; the outer side of the shell is provided with end covers; bosses which can be embedded into the through slots are formed at the middle portions of the end covers; the upper end surfaces of the end covers are provided with installation plates; the lower end surfaces of the end covers are provided with bottom plates; the lower end surface of the shell is provided with stepped grooves; and the inner sides of the stepped grooves are provided with rotation shafts. According to the mobile maintenance power source box for the power grid of the invention adopted, the charging box body is arranged at the inner side of the shell, so that the charging box body can be protected. The mobile maintenance power source box is especially suitable for being applied to electric power construction or maintenance processes.

Description

technical field [0001] The invention relates to a special mobile maintenance power supply box for power grids. Background technique [0002] Existing mobile power boxes are usually equipped with a roller structure, and the pull rod is used to drive the whole box to move. Since the power jack is provided, it is suitable for power maintenance and construction operations, especially for construction and maintenance sites with relatively harsh conditions. When in use, it is easy to be damaged, and in bad weather, the exposed power port is likely to cause a safety hazard due to moisture. Contents of the invention [0003] The purpose of the present invention is to provide a special mobile maintenance power supply box for power grids, which can protect the charging box body by placing the charging box body inside the casing, and is especially suitable for use in electric power construction or maintenance. [0004] The present invention is realized through the following technica...
