Structure schematic diagram.The safety laboratory hood 100 that this utility model provides includes the most successively
The fixing Over-The-Counter 10 connecting setting and lower cabinet 20.Wherein, relative the two of the leading flank of described Over-The-Counter 10
Side is respectively fixed with the first empty column 11 and the second empty column 12, the described first empty column 11 and described
The second opposing parallel interval of empty column 12 is arranged, and both is provided with reverse V-shaped safety device 13,
And the described first empty column 11 is provided with control panel 14.Preferably, the described first empty column 11
With the hollow-core construction cylinder that the described second empty column 12 is metal system, described reverse V-shaped safety
Device 13 is the reverse V-shaped block being prepared from by fine aluminum section bar.
And, the leading flank of described Over-The-Counter 10 is also equipped with the first anti-explosion glass window being fixedly installed
15 and can upwardly open or close downwards the second anti-explosion glass window 16 of setting, described first explosion-proof
Glass vision panel 15 is fixed on the top of described Over-The-Counter 10 leading flank, described second anti-explosion glass window 16
The bottom closing on described first anti-explosion glass window 15 is arranged, and it is empty vertical to be movably arranged as described first
Between post 11 and described second empty column 12, and described second anti-explosion glass window 16 is by described the
The reverse V-shaped safety device 13 of one empty column 11 and the described second empty column 12 fixes.
Wherein, described second anti-explosion glass window 16 is additionally provided with form handle 161, described form handle
Hands 161 is fixed on the bottom of described second anti-explosion glass window 16, the internal peace of described form handle 161
Equipped with two rods 163 connected by spring 162, as shown in Figure 3.
In the present embodiment, described second anti-explosion glass window 16 is completed by described form handle 161
The upwardly opening and close downwards of described second anti-explosion glass window 16.
Further, described form handle 161 is additionally provided with and is individually fixed in described two rods 163
Two movable blocks 164.In the present embodiment, by the movable block 164 on described form handle 161
The contraction of described spring 162 can be realized.If described spring 162 is not being extended or during compression stress,
The most described two rods 163 are internal the most a bit of from described form handle 161 respectively.When to
During described second anti-explosion glass window 16 of upper unlatching, the described rod that described form handle 161 two ends are prominent
Bar 163 can be by the described first empty column 11 and the reverse V-shaped safety device of the described second empty column 12
The obstruction of 13, its Lift is limited, such that it is able to control described safety laboratory hood 100
Operate in the stroke range of safety.
But, when experimenter's job demand opens bigger height, described form handle 161 can be made
On two movable blocks 164 move towards, make the described rod 163 highlighted return to being all retracted
