Detailed description of the invention
Hereinafter, with reference to the accompanying drawings to describe embodiment of the present utility model in detail.However, it is possible to implement this utility model in many different forms, and this utility model should not be construed as limited to the specific embodiment that illustrates here.On the contrary, it is provided that these embodiments are to explain principle of the present utility model and actual application thereof, thus others skilled in the art are it will be appreciated that various embodiment of the present utility model and be suitable for the various amendments of specific intended application.Identical label can be used to represent identical element in entire disclosure and accompanying drawing.
Fig. 1 is the structural representation of the security activity protection window type ventilated chamber according to embodiment of the present utility model.
With reference to Fig. 1, window type ventilated chamber is protected to include according to the security activity of embodiment of the present utility model: ventilated chamber casing 10, the front-operated being arranged on ventilated chamber casing 10 draw window 20, are arranged at front-operated and draw the reinforcing plate 30 on window 20, be arranged at front-operated and draw the portable plate 40 on window 20 and connect knob 50.Ventilated chamber casing 10 has the cavity of one end open, and front-operated draws window 20 to be arranged on ventilated chamber casing 10, to close the open end of described cavity.In the present embodiment, front-operated draws the window 20 can be elevated or draw fall, with open described cavity or close described cavity.In the present embodiment, portable plate 40 and reinforcing plate 30 are made by transparent organic glass；But this utility model is not restricted to this.
Wherein, front-operated draws and offers the first through hole 21 on window 20.Here, in order to avoid front-operated draws the problem declined on window 20 due to the intensity brought after offering the first through hole 21, in this embodiment, it is preferred that, front-operated draws and is provided with the reinforcing plate 30 improving intensity on window 20 around the first through hole 21.In the present embodiment, the first through hole 21 rectangular shaped, but this utility model is not restricted to this.Reinforcing plate 30 is the plate of surrounding band flange, and front-operated draws the reinforcing plate on the outer surface of window and inner surface to be connected by screw, draws the intensity of window increasing described front-operated.
In the present embodiment, draw at front-operated and be respectively provided with reinforcing plate 30 on the outer surface of window 20 and inner surface.Portable plate 40 is positioned on the reinforcing plate 30 that front-operated draws on the inner surface of window 20, connects knob 50 and is positioned on the reinforcing plate 30 that front-operated draws on the outer surface of window 20.Offering the second through hole 31 of four long-elliptical in reinforcing plate 30 on the outer surface that front-operated draws window 20, wherein, this through front-operated of the second through hole 31 draws the reinforcing plate 30 on the inner surface of window 20.Connecting knob 50 draws the outer surface of window 20 to be connected through the second through hole 31 with portable plate 40 from front-operated, and in the present embodiment, connecting knob 50 with portable plate 40 is screwed connection mode；But this utility model is not restricted to this.Unclamping connection knob 50, portable plate 40 can slide up and down along reinforcing plate 30.Additionally, be provided with third through-hole 41 on portable plate 40.Wherein, portable plate 40 is corresponding with the first through hole 21 after being conditioned slip, so that third through-hole 41 is corresponding with the first through hole 21, so, when experimenter tests, staff can sequentially pass through third through-hole 41 and the first through hole 21 stretches into, thus carries out experimental implementation in ventilated chamber.
In the present embodiment, third through-hole 41 is rounded, and it can allow the hands of experiment operator and arm to pass through, and the length and width of the first through hole 21 is all higher than the diameter of third through-hole 41, but this utility model is not restricted to this.
Specifically, in the present embodiment, portable plate 40 can move along reinforcing plate 30, after moving to suitable position, connects knob 50 and is fixed by portable plate 40.Here, the second through hole 31 vertically vertical direction is formed, if be connected connecting the knob 50 second through hole 31 through vertical direction with portable plate 40, portable plate 40 can move up and down by vertical direction.As another embodiment of the present utility model, as in figure 2 it is shown, the second through hole 31 can also be formed along left and right horizontal direction, if be connected connecting the knob 50 second through hole 31 through horizontal direction with portable plate 40, portable plate 40 can horizontal direction side-to-side movement.
The front-operated of the present embodiment draws window 20 to use transparent safety glass to make, to facilitate experiment operator to observe the experimental conditions in ventilated chamber.Further, front-operated draws and is provided with form handle 22 on window 20, wherein it is possible to draw window 20 by promoting or drawing fall form handle 22 to open or close front-operated.
Generally, in ventilated chamber, experimental implementation is divided into three kinds of states: charging, ingredients, reaction.Wherein, during except " charging " state, front-operated can be drawn window 20 to open by experimenter, and other situation all remains off, and forms safety curtain, experimenter is effectively isolated with the experiment in ventilated chamber.The isolation wind cabinet of the present embodiment also includes the exhaust apparatus 24 being arranged at above casing 10 and is arranged at the locker 23 below casing 10；Certainly this is not restricted by this utility model, and this is only an embodiment of the present utility model.
In the present embodiment, front-operated draws and symmetrical on window 20 offers two the first through holes 21, and accordingly, portable plate 40 is also two；But this utility model is not restricted to this, such as, front-operated draws and can also offer 21, three the first through holes 21 of first through hole or more first through hole 21 on window 20；Accordingly, portable plate 40 can also be first and third or more.Additionally, at the present embodiment, the orbital direction of reinforcing plate 22 may be configured as above-below direction and may be alternatively provided as left and right directions, so, portable plate 40 is along reinforcing plate 22 the most slidably；But this utility model is not restricted to this, such as, the orbital direction of reinforcing plate 22 can also be arranged to independent left and right directions type or be individually for above-below direction type.
In sum; according to embodiment of the present utility model; owing to front-operated drawing window move the bottom of described cavity completely to; it is possible to the experiment operator all body parts in addition to hand are made effective isolation with experiment place; so; when there are unexpected (such as blast etc.) in experiment; ventilated chamber is equivalent to a safety curtain; explosion wave can be buffered; block the produced impulsive force of blast and the poisonous and harmful substance of splashing; can preferably Protection personnel, be unlikely to mortal injury.Additionally, ventilated chamber according to embodiment of the present utility model arranges the first through hole by drawing at front-operated on window, and increase has third through-hole portable plate, by portable plate slip near the first through hole, make third through-hole corresponding with the first through hole, so can ensure that experimenter remains to be normally carried out experimental implementation in the case of segregate, use the portable plate of adjustable position, the laboratory technician that can also facilitate differing heights carries out experimental implementation, improves convenience and the suitability of ventilated chamber.
Although illustrate and describing this utility model with reference to specific embodiment, but it should be appreciated by those skilled in the art that: in the case of without departing from the spirit and scope of the present utility model limited by claim and equivalent thereof, the various changes in form and details can be carried out at this.
