Specific embodiment
Hereinafter, with reference to the accompanying drawings to detailed description of the present invention embodiment.However, it is possible to come in many different forms real
The present invention is applied, and the present invention should not be construed as limited to the specific embodiment illustrated here.On the contrary, providing these implementations
Example is in order to explain the principle of the present invention and its practical application, so that others skilled in the art are it will be appreciated that of the invention
Various embodiments and the various modifications for being suitable for specific intended application.Identical label can be used in the whole instruction and attached drawing
Indicate identical element.
Fig. 1 is the structural schematic diagram of the security activity protection window type vent cabinet of embodiment according to the present invention.
Referring to Fig.1, embodiment according to the present invention security activity protection window type vent cabinet include: vent cabinet cabinet 10,
The front-operated being set on vent cabinet cabinet 10 draws window 20, the stiffening plate 30 being set on front-operated drawing window 20, is set to
Front-operated draws movable plate 40 and connection knob 50 on window 20.Vent cabinet cabinet 10 has the cavity of one end open, front
Operation draws window 20 to be set on vent cabinet cabinet 10, to close the open end of the cavity.In the present embodiment, front-operated is drawn
Window 20 can be elevated or draw drop, with the opening cavity or the closing cavity.In the present embodiment, movable plate 40 and stiffening plate
30 are made of transparent organic glass；But the present invention is not restricted to this.
Wherein, front-operated draws and offers first through hole 21 on window 20.Here, in order to avoid front-operated draw window 20 on by
The problem of bring intensity declines after opening up first through hole 21, in this embodiment, it is preferred that, front-operated is drawn to be enclosed on window 20
The stiffening plate 30 for being improved intensity is set around first through hole 21.In the present embodiment, 21 rectangular shaped of first through hole, but this hair
It is bright to be not restricted to this.Stiffening plate 30 is plate of the surrounding with flange, and front-operated draws the reinforcement on the outer surface and inner surface of window
Plate is by screw connection, to increase the intensity that the front-operated draws window.
In the present embodiment, stiffening plate 30 is respectively provided on the outer surface and inner surface that front-operated draws window 20.Movable plate
40 are located on the stiffening plate 30 that front-operated is drawn on the inner surface of window 20, and connection knob 50 is located at front-operated and draws the outer of window 20
On stiffening plate 30 on surface.Strip is oval there are four opening up in the stiffening plate 30 on the outer surface that front-operated draws window 20
Second through-hole 31 of shape, wherein second through-hole 31 penetrates through the stiffening plate 30 on the inner surface of front-operated drawing window 20.Connection rotation
Button 50 draws the outer surface of window 20 to pass through the second through-hole 31 and connect with movable plate 40 from front-operated, in the present embodiment, connection rotation
Button 50 and movable plate 40 are screwed connection mode；But the present invention is not restricted to this.Connection knob 50 is unclamped, movable plate 40 can edge
Stiffening plate 30 slide up and down.In addition, being provided with third through-hole 41 on movable plate 40.Wherein, after movable plate 40 is conditioned sliding
It is corresponding with first through hole 21, thus keep third through-hole 41 corresponding with first through hole 21, in this way, when experimenter tests, people
Hand is protruded into turn through third through-hole 41 and first through hole 21, to carry out experimental implementation in vent cabinet.
In the present embodiment, third through-hole 41 is rounded, and the hand of experiment operator and arm is allowed to pass through, and
The length and width of first through hole 21 is all larger than the diameter of third through-hole 41, but the present invention is not restricted to this.
Specifically, in the present embodiment, movable plate 40 can be moved along stiffening plate 30, be moved to after suitable position, even
It connects knob 50 movable plate 40 is fixed.Here, vertically vertical direction is formed the second through-hole 31, if knob 50 will be connected
The second through-hole 31 across vertical direction is connect with movable plate 40, and movable plate 40 can vertical direction up and down motion.As the present invention
Another embodiment, as shown in Fig. 2, the second through-hole 31 can also be formed along left and right horizontal direction, if connection knob 50 worn
The second through-hole 31 for crossing horizontal direction is connect with movable plate 40, and movable plate 40 can horizontal direction side-to-side movement.
The front-operated of the present embodiment draws window 20 to be made of transparent tempered glass, to facilitate experiment operator to observe
Experimental conditions in vent cabinet.Further, front-operated draws and is provided with form handle 22 on window 20, wherein can be by mentioning
It rises or draws drop form handle 22 to open or close front-operated and draw window 20.
In general, experimental implementation is divided into three kinds of states: charging, ingredients, reaction in vent cabinet.Wherein, in addition to " charging " shape
When state, front-operated can be drawn window 20 to open by experimenter, and other situations remain off, and form safety curtain, will be real
Personnel are tested effectively to be isolated with the experiment in vent cabinet.The isolation wind cabinet of the present embodiment further includes being set to 10 top of cabinet
Exhaust apparatus 24 and be set to the locker 23 of the lower section of cabinet 10；Certainly the present invention is restricted not to this, this is only this hair
Bright one embodiment.
In the present embodiment, first through hole 21 there are two symmetrically being opened up on front-operated drawing window 20, accordingly, activity
Plate 40 is also two；But the present invention is not restricted to this, leads to for example, can also offer one first on front-operated drawing window 20
21, three, hole first through hole 21 or more first through hole 21；Accordingly, movable plate 40 or first and third or
More.In addition, the orbital direction of stiffening plate 22, which may be configured as up and down direction, may be alternatively provided as left and right directions in the present embodiment,
In this way, movable plate 40 along stiffening plate 22 up and down slidably；But the present invention is not restricted to this, for example, stiffening plate 22
Orbital direction also can be set to independent left and right directions type or be individually for up and down direction type.
In conclusion according to an embodiment of the invention, due to by front-operated draw window completely draws arrive the cavity bottom,
So all physical feelings of the experiment operator in addition to hand effectively can be isolated with experimental place work, in this way, working as
When accident (such as explosion etc.) occurs for experiment, vent cabinet is equivalent to a safety curtain, can buffer explosion wave, blocks quick-fried
The poisonous and harmful substance of impact force and splashing caused by fried, can preferably Protection personnel, be unlikely to that mortal wound occurs
Evil.In addition, first through hole is arranged by drawing in front-operated in the vent cabinet of embodiment according to the present invention on window, and increase has
Third through-hole movable plate is kept third through-hole corresponding with first through hole, in this way may be used by sliding of the movable plate near first through hole
To guarantee that experimenter remains to be normally carried out experimental implementation in segregate situation, using the movable plate of adjustable position, also
The laboratory technician that can be convenient different height carries out experimental implementation, improves the convenience and applicability of vent cabinet.
Although the present invention has shown and described referring to specific embodiment, it should be appreciated by those skilled in the art that:
In the case where not departing from the spirit and scope of the present invention being defined by the claims and their equivalents, can carry out herein form and
Various change in details.
