Description

A mobile explosion-proof socket box

technical field

The utility model relates to the field of explosion-proof equipment, in particular to a mobile explosion-proof socket box.

Background technique

In workplaces with explosive hazards, connectors between electrical equipment and power sources, such as power sockets, can only allow sockets with explosion-proof functions. If it is a non-explosion-proof plug, it is very likely to explode when inserted, causing irreparable consequences.

Existing explosion-proof device mainly contains explosion-proof box and explosion-proof plug, socket to form, and explosion-proof box is inconvenient to connect electricity, can not plug and connect electricity. The plug-in and power-on of the explosion-proof socket must be equipped with a special explosion-proof plug, which is not universal, and it is very inconvenient to power on various common electrical appliances and electronic equipment used in hazardous chemical places. If ordinary plugs and sockets are used to plug and unplug the power, it is likely to cause an explosion and produce unpredictable consequences.

Contents of the invention

The purpose of the utility model is to solve the above problems and provide a mobile explosion-proof socket box.

In order to realize the purpose of the utility model, the technical scheme that the utility model adopts is:

A mobile explosion-proof socket box, including a box body and a box cover. The box body and the box cover are connected by a hinge. The box cover has a buckle for closing the box body. The base, the base is fixed on the bottom surface by the corner bolts around it, and the plug board is fixed on the base, and an explosion-proof switch is embedded on one side of the box body. The knob of the explosion-proof switch is exposed outside the box body, and the power supply line of the plug board It is introduced from a small hole on one side of the box, passes through the explosion-proof switch, and then connected to the plug-in board. There are several grooves on the side of the box for several plugs to enter the line. There are sealing rings in the groove and the small hole. , There is a gasket on the upper edge of the side of the box to seal the gap between the box and the box cover.

The beneficial effects of the utility model are that: the explosion-proof function of the socket is improved, the conversion performance of the socket is improved, and the explosion-proof function of a plurality of commonly used electrical equipment in a movable environment is realized. The explosion-proof socket box is no longer fixed in one place, and the switchable distance of the socket is increased, which is convenient for mobile use at any time. The aesthetic level of the wiring in the explosion-proof box is increased, and it is suitable for all kinds of electrical appliances and electronic equipment with movable and multi-purpose explosion-proof plug-in and power-on.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment: See Fig. 1, Fig. 2, Fig. 3.

A mobile explosion-proof socket box, including a box body 1 and a box cover 2, the box body 1 and the box cover 2 are connected by a hinge, the box cover 2 has a hasp 3 for closing the box body, the box body is rectangular, A base 6 is arranged on the bottom surface of the box body 1, and the base 6 is fixed on the bottom surface by corner bolts 8 around it. The plug-in board 7 is fixed on the base 6, and an explosion-proof switch 4 is embedded and installed on one side of the box body 1. The explosion-proof switch The knob of 4 is exposed on the outside of the box body 1, and the power supply line 9 of the plug-in board 7 is introduced from the small hole 11 on one side of the box body and then connected to the plug-in board 7 after passing through the explosion-proof switch 4. A number of grooves 10 are provided for several plugs to enter the line. There are sealing ring pads 5 in the grooves 10 and the small holes 11. There are sealing ring pads 5 on the upper edge of the side of the box body for sealing the gap between the box body 1 and the box cover 2. gap.

Design Note: When the circuit is plugged and unplugged, it is easy to explode. The main reason is that when the switch is inserted, the circuit is turned on immediately, and the explosion-proof box is in the open state at this time. Therefore, an outward-facing explosion-proof rotary switch is set in the explosion-proof box to separate the plugging of the switch in the explosion-proof box from the conduction of the circuit. The conduction and disconnection of the circuit are determined by the explosion-proof switch facing outward on the explosion-proof box. When the rotary switch is operated, the explosion-proof box is in the closed state, which has explosion-proof common energy. In order to contain the spark from the source and further expand the explosion, combined with the combustion conditions, a sealing ring is added at the joint of the explosion-proof box and the inlet and outlet holes to prevent the outside air from further entering the explosion-proof box when the explosion-proof box is closed, and remove the necessary for combustion. condition. Considering that the existing explosion-proof box is fixed on the wall, it is inconvenient to move, and it must be plugged and plugged with a special plug, which is difficult to realize for electrified electrical appliances and electronic equipment. Electrical appliances and electronic equipment usually need to be used on the move, and special explosion-proof sockets fixed on the wall cannot meet the demand. Now a multi-purpose socket is reinforced by a metal plate, the socket in the box is connected with the metal plate, and fixed in the high-performance explosion-proof box by four long screws. The fixedness of the socket is increased, and the sealing of the explosion-proof box is increased, so the fixing device of the explosion-proof box is subtracted, and the explosion-proof box is converted into a movable device. The space under the socket can be used for wiring, and redundant wires can be placed under the socket in an orderly manner. When the device is not in use, the peripheral connecting wires can also be placed under the socket and in the surrounding space in an orderly manner. On one side of the high-performance explosion-proof box, an explosion-proof rotary switch is installed to control the input and output of the power supply.

The disclosed embodiment of the utility model is one of the preferred embodiments, but it is not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the utility model according to the above-mentioned embodiments, and make different Extensions and changes, but as long as they do not depart from the spirit of the utility model, are all within the protection scope of the utility model.
