Description
Technical Field
The invention belongs to the technical field of distribution box devices, and particularly relates to an explosion-proof distribution box.
Background
The lighting distribution box is a basic distribution device which reasonably combines and assembles a current action protector, an air circuit breaker and the like in the lighting distribution box, thereby realizing the centralized control of a household power supply and the protection functions of grounding, overload, short circuit and the like. And the interior of the transformer is also respectively provided with a bus bar for protecting a grounding wire and a neutral wire so as to facilitate the wiring of various low-voltage distribution systems. The lighting distribution box is widely used in various buildings, squares, stations, industrial and mining enterprises and other places as terminal electrical equipment of a distribution system.
It is often necessary to open the cabinet for maintenance, and to ensure safe operation, the interior electrical components must be powered down before the cabinet door is opened. If adopt electronic component to control, then electronic component needs the circular telegram, can not accomplish thoroughly the outage to electronic component cost is higher, consequently needs improve the block terminal structure, requires the block terminal when the circular telegram, and the chamber door can not be opened, just can pull open the chamber door when the outage.
Disclosure of Invention
The invention aims to solve the problems and provides an explosion-proof distribution box.
In order to solve the problems, the technical scheme adopted by the invention is as follows:
explosion-proof block terminal, including box, chamber door, electric elements, inside electric elements was located the box, the chamber door lateral part passed through the articulated shaft with the box and articulated, its characterized in that, electric elements's total control switch sets up on the chamber door, total control switch is the knob formula, is equipped with the bump on total control switch's the center pin, is equipped with on the chamber door and can presses down the bolt, can press down and be equipped with reset spring on the bolt, and the bottom half is equipped with the jack, and when total control switch is located closed state, the bump is located and can presses down directly over the bolt, and the bump is pressed down and can be pressed down the bolt, can press down.
Furthermore, a pressing plate is arranged at the top of the pressable bolt and is arc-shaped or triangular.
Furthermore, a visible transparent window is arranged on the box door, and the visible transparent window is made of explosion-proof glass.
The invention has the beneficial effects that:
when the box door is closed, referring to the attached figure 2 of the specification, the main control switch is rotated to close the circuit and electrify the main control switch, the convex points are right opposite to the tops of the pressable bolts, the pressable bolts are pressed downwards by the convex points, the bottom ends of the pressable bolts are inserted into the corresponding jacks of the box body, and the box cover is locked at the moment. When the box door needs to be opened, referring to the attached drawing 3 in the specification, the main control switch is rotated to disconnect the circuit, the power is off, the salient point is separated from the push bolt, the push bolt can be pushed under the resilience force of the reset spring, the bottom of the push bolt can be pushed to separate from the socket, and the box door can be opened.
According to the explosion-proof distribution box, the mechanical structure is improved, the explosion-proof distribution box can be opened only under the condition of power failure, and the safe operation is ensured.

Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more readily understand the advantages and features of the present invention and to clearly and unequivocally define the scope of the present invention.
Referring to the attached drawings 1 and 2 in the specification, the explosion-proof distribution box comprises a box body 1, a box door 2 and an electric element 3, wherein the electric element 3 is located in the box body 1, and the side part of the box door is hinged with the box body through a hinge shaft. The main control switch 4 of the electric element is arranged on the box door 2, the main control switch is of a knob type, a convex point 42 is arranged on a central shaft 41 of the main control switch, the box door is provided with a press bolt 5, the press bolt is provided with a reset spring 51, and the bottom of the box body is provided with a jack. The lower end of the reset spring is pressed by the fixing ring 11 on the box door, and the bottom end of the bolt can be pressed by the reset spring to be separated from the jack in a natural state. When the master control switch is in a closed state, the salient point is positioned right above the pressable bolt, the pressable bolt is pressed downwards by the salient point, the bottom end of the pressable bolt is inserted into the jack, and the box door cannot be opened at the moment; when total control switch is located the off-state, the bump breaks away from and can presses the bolt, under reset spring's resilience force, can press the bolt and be upspring by upwards, can press the bolt bottom and break away from the jack, and the chamber door can be opened this moment.
Furthermore, a pressing plate 52 is arranged at the top of the pressing bolt, and the pressing plate is arc-shaped or triangular. Reset spring upper end is blocked by the pressure board, and when total control switch was rotatory, the bump on the center pin was rotatory along with its center axis, and the bump directly presses the pressure board on, under the bearing of pressure board, the bump can forward butt joint with can pressing the bolt.
Further, a visible transparent window 21 is arranged on the box door, and the visible transparent window is made of explosion-proof glass. The visual transparent window of accessible observes its inside situation, just opens the chamber door when needs overhaul.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, that the preferred embodiments of the present invention are described above and the present invention is not limited to the preferred embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the present invention and these changes and modifications are within the scope of the invention as claimed.
