Abstract

The utility model discloses a smoke outlet of detachable panels. The utility model is characterized in that the utility model comprises two panels, and one end of one panel is provided with a locking mechanism and an unlocking mechanism; one end of the other panel is fixed with a spring hinge, and a spring hinge is arranged between the two panels. In the utility model, a fire prevention valve body is provided with two foldable panels which form two structures which can work independently, therefore, the panel which performs sealing function in the state of safety can be made of plywood or other materials which coordinate with indoor decoration, and the purposes that the panel has beautiful appearance and the working performance of the smoke outlet is not influenced are achieved.

Description

A kind of exhaust opening of folding panel

The utility model relates to a kind of security against fire device, a kind of exhaust opening of folding panel specifically, and it can be installed in the place, gateway of the smoke shaft or the supply and exhaust pipe of building, has the function of smoke evacuation and air-supply.

Exhaust opening is an indispensable firefighting security device in having the building of mechanical smoke extraction.Two types exhaust opening is arranged at present, a kind of is leafy exhaust opening, another kind is board-like exhaust opening, these two kinds of exhaust openings are because of being subjected to the restriction of this body structure, so can only make of steel plate, not only outward appearance can't be coordinated mutually with upholster, and because of board-like exhaust opening can not fold, opens the normal walking that can influence the resident.

The exhaust opening that is to provide a kind of folding panel of the present utility model, it can be coordinated mutually with indoor decoration, does not influence its normal work again.

The technical solution of the utility model is achieved in that a kind of exhaust opening of folding panel, it mainly comprises the fire prevention valve block that is contained in the valve body, the molten part of the temperature that matches with valve block, swing arm, connecting rod and spring, be contained in the panel on the valve body, be fixed on the interior retaining mechanism that matches with panel of valve body, take off latch mechanism and pneumatic buffer device, it is characterized in that: panel is formed by two, retaining mechanism is housed, takes off latch mechanism at an end of a panel; One end of another piece panel is fixed with spring hinge, and spring hinge also is housed between two panels.

The utility model is owing to be provided with two folding panels on the fire prevention valve body, two structures that can work alone have been formed, the panel of exhaust opening is in closed condition when safe, in the time of when fire takes place, maybe need discharging fume air-supply, with the electronic or manually opened latch mechanism that takes off, panel opening is discharged fume or is blown, the panel of opening can not influence people's walking, when exhaust gas temperature reaches certain temperature (280 ℃ of examples), fire resisting damper can be closed voluntarily, stop fire spreading, so the panel that plays sealing process that is under the safe condition just needn't adopt the metal material of fire-resistant requirement to make, can select for use glued board or other to make with the material that upholster is coordinated mutually, thereby realize that the panel that both made of the present utility model is attractive in appearance, do not influence the purpose of exhaust opening service behaviour again.

The utility model will be further described below in conjunction with drawings and Examples

The utility model mainly comprises the two fire prevention valve blocks 2 that are contained in the valve body 1, the two valve blocks 2 all axle by separately 22 are set in the valve body, between two valve blocks all a swing arm 4 and the connecting rod 5 by separately be connected, one end of-valve block is connected with valve body 1 by the molten part 3 of temperature, and the swing arm 4 of another valve block is connected with valve body 1 by spring 6; Two panels 7 are housed on valve body, 8, end at panel 7 is equipped with the pneumatic buffer device, this buffer unit adopts an inflator 11, and link to each other with connecting rod 13 by inflator axle 12, end by lever 14 and a connector 15 and a panel 7 fixes again, leather cup 29 is housed in the inflator 11, the bottom of inflator 11 is connected with framework 19, this panel also with the retaining mechanism that is fixed in the valve body, taking off latch mechanism is connected, retaining mechanism adopts: a cavity 16 is arranged at the back side of a panel 7, be fixed with a metal derby 17 near cavity 16 places, in valve body, also be provided with framework 19, one mobilizable lock dog 23 is housed on framework 19, and lock dog 23 is provided with the grab 18 that matches with metal derby; Take off latch mechanism electronic and manual two parts are arranged, no matter be to open electronic or manual part all can make retaining mechanism take off lock, the electronic latch mechanism that takes off comprises the electromagnet 20 that is fixed on the framework, the extension spring 21 that matches with electromagnet, pull bar 24, the spin-block 25 that is connected with lock dog 23, pull bar 24 respectively; The manual latch mechanism that takes off comprises successively: manually shake hands 26, open lever 27, steel wire 28 and spin-block 25, an end of another piece panel 8 is equipped with spring hinge 9, and promptly this spring hinge 9 is connected with an end of panel 8 by framework 19; 8,9 of two panels spring hinge 10 is housed also.The place of touching at two panels and valve body also can be provided with sealing ring, to strengthen its sealing.

18 lockings of the grab on the lock dog 23 in the mechanism that are locked of the metal derby 17 of the utility model on safe condition lower panel 7, when electromagnet 20 gets electric adhesive pull bar 24, drive spin-block 25 by pull bar 24, drive lock dog 23 by spin-block 25 again, grab 18 is separated with metal derby 17, this moment the twisting force lower panel of spring hinge 9 shift out valve body on the plane, two panels fold simultaneously, can eliminate panel under the effect of the inflator in the pneumatic buffer device and open the inertia that is produced when rotating, can discharge fume or blow after opening panel, when the temperature of exhaust opening reaches certain temperature, when for example reaching 280 ℃, the molten part 3 of 280 ℃ temperature disconnects, be contained in the spring 6 pulling swing arms 4 in the valve body 1, valve block 2 is closed, stop fire spreading.
