Abstract

A frameless explosion release window comprises essentially column stands, a fixing board, a baffle and the window body, wherein the column stands are U-shaped, the fixing board is positioned at the upper margins of the two column stands and has hinges at the lower part, the window body has a fixing frame grooving within and a vertical step, the window body is connected via the step to the hinges of the baffle and appears openable, the lower part of the window body is provided with the baffle to connect with the lower margin of the window body via an explosion release bolt and form the explosion release window. When gas explosion occurs indoor, the window body will be open outward via the ruptured explosion release bolt so that the explosive damage is reduced.

Description

No frame venting of dust explosion window

Technical field:

The utility model relates to a kind of no frame venting of dust explosion window, refer to especially a kind of can be when indoor generation gas explosion moment open and its venting of dust explosion window construction easy to assembly.

Prior art:

Places such as general warehouse, factory, its window is able to the moment unlatching when unfortunately producing gas explosion for making, and to reduce the extent of damage of blast, normally is provided with the venting of dust explosion window.Known venting of dust explosion window comprises window frame and forms usually, forms are connected with window frame with the axostylus axostyle of both sides, being able to moment when gas explosion produces releases forms, to reduce the infringement of blast, these known venting of dust explosion windows are because comparatively inconvenience of the assembling of forms and window frame, and when if the venting of dust explosion window is large-scale, more influence operating efficiency because of window frame is difficult for making up, make assembly cost improve relatively, very undesirable.

Summary of the invention:

Main purpose of the present utility model promptly in that a kind of no frame venting of dust explosion window is provided, makes the assembling of venting of dust explosion window more convenient, improves the practicality of operating efficiency and venting of dust explosion window.

Venting of dust explosion window construction of the present utility model comprises column, fixed head, plate washer and forms, wherein, this column is the U shape, this fixed head is located at two column upper limbs, and its below is provided with hinge, and these forms then are equipped with fixed frame, and edge is provided with a vertical rank portion thereon, forms are connected with the hinge of fixed head by this rank portion, make it be to lift and close shape, and establish with baffle plate in the forms below, its lower edge is connected, to constitute a venting of dust explosion window with plate washer with the venting of dust explosion bolt.

Adopt above technical scheme, when indoor generation gas explosion,, forms are outwards opened, to reach the venting of dust explosion effect that reduces the blast infringement by the venting of dust explosion bolt of fracture.

Fig. 1 is a stereogram of the present utility model.

Fig. 2, Fig. 3 are three-dimensional exploded views of the present utility model.

Fig. 4 is a structure chart of the present utility model.

Fig. 5 is breakdown action figure of the present utility model.

Primary clustering symbol description among the figure:

1. column 2. fixed heads 3. baffle plates 4. forms 5. venting of dust explosion bolts 21. hinges 31. catch 41. groovings 42. fixed frames 43. rank portions

The specific embodiment:

Please consult Fig. 1, Fig. 2 simultaneously, and cooperation Fig. 3, the utility model mainly comprises column 1, fixed head 2, plate washer 3 and forms 4, wherein, these columns 1 (present embodiment is to be three) are the U shape, and its opening edge is made as and bends inwards, and this fixed head 2 generally is the L shape, it is located at the upper limb of 1 on two columns, is provided with spaced hinge 21 in its below;

This baffle plate 3 is strip, and its upper limb is provided with vertical catch 31, and these forms 4 are provided with the grooving 41 of inner edge, and in the fixed frame 42 of these grooving 41 side's of being equipped with shapes, and edge is provided with a vertical rank portion 43 thereon;

Combination by aforementioned components, make forms 4 rely on this rank portion 43 to be connected with the hinge 21 of fixed head 2, make it be to lift and close shape, and establish with baffle plate 3 in the below of forms 4, forms 4 lower edges are connected with the catch 31 of plate washer 3 with venting of dust explosion bolt 5 (referring to Fig. 4), constituting a no frame venting of dust explosion window, when indoor generation gas explosion, make 5 fractures of venting of dust explosion bolt by gas explosion pressure, and then forms 4 are outwards opened, to reach to reduce the venting of dust explosion effect of blast infringement.

See also Fig. 4, the utility model is after assembling, and wherein these forms 4 are to be connected with the hinge 21 of fixed head 2 with rank portion 43, and forms 4 lower edges are connected with plate washer 3 with venting of dust explosion bolt 5 and are sealed shape, formation one venting of dust explosion window under normality.

See also Fig. 5, the utility model is when indoor generation gas explosion, the pressure that gas explosion produced will make venting of dust explosion bolt 5 rupture in moment, and then make forms 4 because of pushing away before the pressure, and 21 be that fulcrum is outwards opened to be hinged, reach the purpose of venting of dust explosion, certainly, after forms 4 are unlocked, it can be closed back and lock new venting of dust explosion bolt 21 again, to reply the function of venting of dust explosion window.

In sum, the utility model cooperates the forms that are provided with the venting of dust explosion bolt to be provided with the column of fixed head, make the venting of dust explosion window constitute certain venting of dust explosion effect, and it is easy to assembly, is the design of a practicality.
