Abstract
The utility model relates to a flame-proof casing with double cavities and double doors, which comprises a hollow cavity of a wiring chamber, leading-in devices, a main cavity and operating handles of an auxiliary locking device, wherein the main cavity is square. The hollow cavity of the wiring chamber can be divided into a hollow cavity of a left wiring chamber and a hollow cavity of a right wiring chamber, wherein the hollow cavity of a left wiring chamber and the hollow cavity of a right wiring chamber can be independently used. The main cavity is divided into a left main cavity and a right main cavity, wherein the left main cavity and the right main cavity can be independent used, and the hollow cavity of a left wiring chamber and the hollow cavity of a right wiring chamber are both provided with the leading-in devices. The left main cavity is provided with a left square door, the right main cavity is provided with a right square door, and the left and the right square doors are rapidly opened door structures in a sideward opened type, wherein the left and the right square doors are rotated by door shafts and are controlled to be opened or closed by the operating handles of an auxiliary locking device. With the utility model, the arrangement and the assembly of inner devices are both easy, the normal operation of the devices can be effectively ensured and cost is low.
Description
One, affiliated technical field
Affiliated technical field the utility model relates to flame-proof type electrical equipment, refers in particular to a kind of two-door flameproof enclosure of two-chamber that is used for flame-proof type electrical equipment.
Two, background technology
Flame-proof type electrical equipment is to utilize restriction and the cooling effect of the explosion insulation performance of flameproof enclosure to explosion product and flame, makes the principle of its unlikely explosive mixture of lighting housing exterior and designs.The main distinction of it and universal basic electric appliance series just is to have explosion-resistant enclosure, and the electric elements in the shell then are to derive from the basis of the basic series of low-voltage electrical apparatus, and therefore, flameproof enclosure is the main key component of flame-proof type electrical equipment.Flameproof enclosure generally is made up of wiring chamber cavity, introducing device, main chamber, operating grip (with interlock) etc.At present, domestic shell mainly contains two classes.One class is cylindrical main chamber, the circular fixing structure formula of former Soviet Union's design.Their advantage is that manufacturing and technology are all fairly simple, low cost of manufacture, and explosion insulation performance is reliable; Shortcoming is that relatively difficulty is arranged and assembled to inner components and parts, can not reasonably utilize the space.Another kind of is the square main chamber of Germany's design, square door, and adopts the quick opening structure formula of cam method or alternate manner.Their advantage is reasonably to have utilized the space, designs also fairly simplely, and characteristics are square chest quick operating valves; Shortcoming is the manufacturing process complexity, and the required precision height is made relatively difficulty, therefore, and with respect to the cost height of the main chamber of circle circular seam lid structural formula.Their common drawback can not be arranged the two-way control circuit simultaneously.
Three, utility model content
Task of the present utility model is to overcome the defective that above-mentioned prior art exists, and provides a kind of two-chamber two-door flameproof enclosure, uses it, and inner components and parts are arranged and assembled all than being easier to, and can guarantee effectively that equipment normally moves, and low cost of manufacture.
In order to finish above-mentioned task, the solution that the utility model is taked is: the two-door flameproof enclosure of a kind of two-chamber, comprise wiring chamber cavity, introducing device, main chamber, the operating grip of attached locking device, main chamber is square, wiring chamber cavity is divided into independent used left wiring chamber cavity and right wiring chamber cavity, main chamber is divided into main chamber, an independent used left side and right main chamber, left side wiring chamber cavity and right wiring chamber cavity all are with introducing device, main chamber, left side band left shape door, the right-hand shape door of right main chamber band, left shape door and right-hand shape door are quick opening structure, rotate by door-hinge, laterally opened, respectively by the operating grip control Push And Release of separately attached locking device.
It is one that this reality has the advantage of the above-mentioned prior art of novel collection, has overcome simultaneously the defective that they exist again, has brought convenience by laterally opened structure for the layout and the design of its inner components and parts, and it is very convenient to open the door simultaneously and close the door.The utility model had both made the user easy to use under the prerequisite that guarantees reliable explosion insulation performance, had reduced manufacturing cost again.Its most outstanding advantage is: can arrange the two-way control circuit simultaneously, and one tunnel outage, another road can operate as normal, and the outage side is if need maintenance can not influence another road operate as normal, and assurance equipment normally moves.It is a kind of pervasive desirable flameproof enclosure.

Among the figure: 1, wiring chamber cavity, 2, introducing device, 3, main chamber, 4, right-hand shape door, 5, left shape door, 6, base, 7, operating grip, 8, right main chamber, 9, right wiring chamber cavity, 10, left wiring chamber cavity, 11, left main chamber.
Five, embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1-Fig. 4, the two-door flameproof enclosure of a kind of two-chamber, comprise wiring chamber cavity 1, introducing device 2, main chamber 3, the operating grip 7 of attached locking device, main chamber 3 is square, wiring chamber cavity 1 is divided into independent used left wiring chamber cavity 10 and right wiring chamber cavity 9, main chamber 3 is divided into main chamber 11, an independent used left side and right main chamber 8, left side wiring chamber cavity 10 and right wiring chamber cavity 9 all are with introducing device 2, main chamber, a left side 11 band left shape doors 5, right-hand shape door 4 is with in right main chamber 8, and left shape door 5 and right-hand shape door 4 are quick opening structure, rotate by door-hinge, laterally opened, respectively by the operating grip 7 control Push And Releases of separately attached locking device.
Referring to Fig. 1-Fig. 4, main chamber 3 is installed on the base 6, is convenient to move.
