Description

The explosion-proof display of restriction breathing

Technical field

It is 2 districts, humidity, the electric field of display devices in dust place that the utility model belongs to restriction breathing electrical apparatus for explosive atmospheres field, particularly explosive gas atmosphere.

Background technology

Be that the display product that uses of the dangerous place in 2 districts is a lot of at explosive gas atmosphere at present, some place also exists steam, mist, dust etc. simultaneously, and when therefore requiring display to have explosion-proof performance, also requirement has high barrier propterty.

Be that the display of the dangerous place use in 2 districts is made the flame-proof type explosion-proof form more now at explosive gas atmosphere, appearance heaviness at first, appearance is not too attractive in appearance by contrast, causes mass excess simultaneously, and cost increases thereupon.

The utility model content

The purpose of this utility model is to provide a kind of explosion-proof display that uses in explosive gas atmosphere is 2 districts, press restriction breathing electrical apparatus for explosive atmospheres standard design, provide a kind of rational in infrastructure, novel in design, be convenient to the solution making and use.

The purpose of this utility model is achieved in that the explosion-proof display of restriction breathing, it is characterized in that: display has two display screens [1], display respectively is screwed a display screen [1] on two doors [6], and be contained in the casing [7], two sight glass [2], respectively by external thread post [15], rubber cushion [3], pressing plate [9] is pressed on the door [6] with nut [8], form an enclosure space with casing [7], casing [7] and two doors [6] internal threaded column [14], screw [5], hinge axis [11] is fastening, sight glass [7] is bonding with fluid sealant with door [6] binding face, two display screens [1] panel has angle, and cable splice [10] is equipped with in the casing side.

Compared with prior art, the beneficial effects of the utility model are: be convenient to make easy to use, novel in design, light and handy, easy for installation, safe and reliable, the raising life-span.When having explosion-proof, barrier propterty, lighter and handier, attractive in appearance than common flame-proof type display profile, be convenient to carrying, install, cost reduces relatively.

Fig. 2 is a structural representation side view of the present utility model; Among the figure: 1 display screen, 2 sight glass, 5 screws, 6,7 casings, 11 hinge axis, 13 suspension brackets.

Fig. 3 is the enlarged drawing in A indication zone among Fig. 2; Among the figure: 1 display screen, 2 sight glass, 3 rubber cushions, 4 sealing strips, 5 screws, 6,7 casings, 8 nuts, 9 pressing plates, 14 internal threaded columns, 15 external thread posts.

Embodiment

With reference to the accompanying drawings, the utility model is further described:

Referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3: the explosion-proof display of restriction breathing, it is characterized in that: display has two display screens [1], display respectively is screwed a display screen [1] on two doors [6], and be contained in the casing [7], two sight glass [2] are respectively by external thread post [15], rubber cushion [3], pressing plate [9] is pressed on the door [6] with nut [8], form an enclosure space with casing [7], casing [7] and two doors [6] internal threaded column [14], screw [5] and nut [8], hinge axis [11] is fastening, sight glass [7] is bonding with fluid sealant with door [6] binding face, two display screens [1] panel has angle, and cable splice [10] is equipped with in the casing side.Threaded cable splice [10] passes mounting hole, and nut screwing clamping is used in inside, and cable splice [10] is used to pass in and out cable.

Described two display screen panel angles are 0 °～90 °.

Described display is stained with sealing strip [4] at the place, doorway, compresses with the casing doorway.Sealing strip and fluid sealant can stop gas, steam, mist etc. to enter casing, make the junction box when having the restriction breathing explosion-proof performance, have possessed high barrier propterty again, improve life of product.

Be connected with suspension bracket [13] on the described casing [7].Explosion-proof display can be hung on the roof by suspension bracket [13] or removed suspension bracket [13] and be placed on other stilt.

The utility model is used to have 2 districts of the dangerous place with a potential explosion of requirement of shelter, or uses in the corrosivity, humidity, mist environment.Explosive-proof grade can reach ExnRIIT6, degree of protection IP66.According to the setting height(from bottom) requirement, two display surfaces are made the interior certain angle of 0 degree～90 degree scopes, and with suitable people's sight line, and the people can watch on the two sides, front and back.
