Abstract
The utility model provides a flameproof shell, which comprises a wiring chamber empty cavity, a wiring device, a main cavity and an operation handle. The main cavity is square shape, a door is a circular stop cap, and the center of the circular stop cap is supported by a rotary arm type rotation axis. The rotary arm type rotation axis supports the center of the circular stop cap, and the engagement and rotation of a stopper of the circular stop cap can not be affected. The circular stop cap is not released from the main cavity by the rotary arm type rotation axis, thus bringing the conveniences to the layout and design of the internal components, meanwhile the feature of the fast opening of the door of the square-shaped main cavity fast opening structure type flameproof shell is maintained, and both the closing and opening is very convenient. The utility model can not only bring convenient to the users but also reduce the manufacturing cost under the precondition of ensuring reliable performance of the flameproof, and is the universal ideal flameproof shell.
Description
One, affiliated technical field
The utility model relates to flame-proof type electrical equipment, refers in particular to a kind of flameproof enclosure 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.Therefore, flameproof enclosure is the main key component of flame-proof type electrical equipment.Flameproof enclosure generally is made up of wiring chamber cavity, line leading device, main chamber, operating grip (with interlock) etc.At present, flameproof enclosure mainly contains two classes both at home and abroad.One class is cylindrical main chamber, the circular fixing structure formula (referring to Fig. 1 and Fig. 2) 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 inner components and parts are arranged and difficulty is all compared in assembling, 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 (referring to Fig. 3 and Fig. 4) 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.
Three, summary of the invention
Task of the present utility model is to overcome the defective that above-mentioned prior art exists, and a kind of flameproof enclosure is provided, and uses it, inner components and parts arrange and assembling all than being easier to, and low cost of manufacture.
For finishing above-mentioned task, the solution that the utility model is taked is: a kind of flameproof enclosure, comprise wiring chamber cavity, line leading device, main chamber, operating grip, and main chamber is square, door is circular seam lid, has a swing-arm type rotation axis to support the central point of circular seam lid.
The advantage of the above-mentioned prior art of the utility model collection (a kind of cylindrical main chamber circular fixing structure formula flameproof enclosure, a kind of rectangle master chamber quick opening structure formula flameproof enclosure) has overcome the defective of they existence simultaneously again in one.Owing to be provided with a swing-arm type rotation axis, this swing-arm type rotation axis supports the central point of circular seam lid, do not influence the seam engagement and rotation of circular seam lid, circular seam lid does not break away from main chamber by the swing-arm type rotation axis again, thereby, arrange and design brings convenience that for the components and parts of its inside kept the characteristics of the square chest quick operating valve of rectangle master chamber quick opening structure formula flameproof enclosure simultaneously, it is very convenient to open the door 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, was a kind of pervasive desirable flameproof enclosure.
