Description

Technical Field

[0001] The utility model belongs to the technical field of distribution boxes, in particular to an outdoor low-voltage distribution box. Background Art

[0002] The distribution box is the control center that directs the rational distribution of electric energy among various components in the power supply line. It is the control link that reliably receives the upper power supply and correctly feeds the load electric energy. When used on the construction site, the distribution box needs to be moved to any position so that the distribution box can be used normally. The wiring on the distribution box changes with the progress of the construction. The on-site lines are complicated. When the wires are tightened too much, they are easy to fall off from the distribution box, and there are no safety warnings during the process. There is a greater safety risk when the incoming wires of the distribution box fall off. In order to add a safety warning device to the distribution box, this application document provides a low-voltage distribution box for outdoor use. Utility Model Content

[0003] The purpose of the utility model is to provide a low-voltage distribution box for outdoor use. Through the coordinated use of a wire clamp, a self-resetting push button switch and a buzzer, once the external wires are excessively pulled, the buzzer will sound an alarm to promptly remind the workers on the construction site to pay attention to electrical safety.

DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment one:

[0029] See also Figure 1-6As shown, the utility model is a low-voltage distribution box for outdoor use, including a box body 1, a box door 2, a bracket 3, a buzzer 4, a self-reset button switch 5, a spring 6 and a clamping plate 7. The buzzer 4 and the self-reset button switch 5 draw power from the distribution box. When the clamping plate 7 presses the self-reset button switch 5, the buzzer 4 is turned on and emits a buzzing sound. The box body 1 is fixed on the bracket 3. The buzzer 4 is installed on a side wall inside the box body 1. A rectangular through hole 11 is opened at the lower end of the box body 1. A guide rod 12 is fixed on the four corners of the rectangular through hole 11 on the inner bottom surface of the box body 1. A spring 6 is respectively installed on the four guide rods 12. The clamping plate 7 is slidably installed on the four guide rods 12. The self-reset button switch 5 is on the inner bottom surface and is located directly below the clamping plate 7.

[0030] To facilitate direct access to power from the housing 1 through the socket, an explosion-proof socket 8 is installed through one side of the housing 1. Furthermore, to protect the socket 8, a protective enclosure 13 is fixed to the same side wall of the housing 1, surrounding the socket 8. A recess 14 is defined in the lower wall of the protective enclosure 13. A hinged flap is mounted on the upper end of the opening.

[0031] The bracket 3 specifically comprises a rectangular ring plate 31 fixedly connected to the bottom of the box 1. Symmetrically fixed to the lower surfaces of opposite ends of the rectangular ring plate 31 are H-shaped fixed support legs 32 that extend outward. The bracket 3 lifts the box 1 off the ground, protecting it from rain and moisture, and facilitating the installation and routing of the distribution box's wiring.

[0032] Among them, the wire clamping plate 7 includes a floating clamping seat 71 and a clamping plate 72. The floating clamping seat 71 includes a rectangular plate body 711. Four guide circular holes 712 that slide with the guide rod 12 are provided on the rectangular plate body 711. A rectangular notch 713 is provided on one side of the rectangular plate body 711. A U-shaped groove plate 714 that is perpendicular to the rectangular plate body 711 is fixed to the inner bottom surface of the rectangular notch 713. A circular arc inner recess 715 is provided in the middle of the U-shaped groove plate 714. The U-shaped groove plate 714 is provided with a row of first threaded through holes 716 on both sides of the circular arc inner recess 715. The clamping plate 72 and the U-shaped groove plate 714 are connected by two rows of bolts 73. A plurality of U-shaped groove plates 714 that cooperate with the clamping plate 72 for clamping and fixing the installed wires are provided on the wire clamping plate 7. The provided U-shaped groove plates 714 further facilitate the clamping, installation and positioning of the cable. The cables entering and exiting the electrical equipment installed in the distribution box are clamped on the wire clamping plate 7. When the external wires are pulled, the spring 6 is compressed, and the wire clamping plate 7 moves downward to squeeze the self-reset button switch 5 below. When the switch is powered on, the buzzer 4 sounds an alarm to remind the staff on the construction site that the wires entering and exiting the distribution box are subject to excessive pulling, posing a risk of electrical use.

[0033] One side of the clamping plate 72 is provided with a circular protrusion 721. Two rows of circular through holes 722 are formed on the clamping plate 72 to accommodate the bolts 73. For smaller cables, the side of the clamping plate 72 with the circular protrusion 721 is placed against the U-shaped groove plate 714. The circular protrusion 721 corresponds to the circular recess 715 to clamp and secure the small-diameter cable.

[0034] A circular rubber plate 717 is fixed to the inner wall of the concave portion 715. A rubber gasket 723 is fixed to the other side of the clamping plate 72. The outer surface of the rubber gasket 723 is provided with a toothed groove 724. The presence of the circular rubber plate 717 and the rubber gasket 723 increases friction against the surface of the wire, improving the stability of the cable clamp during installation.
