Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model vent cabinet.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, in ventilation hoods for laboratories first embodiment of the present utility model, this vent cabinet 1 comprises cabinet 2, be arranged at lower cabinet 16 below cabinet 2, be arranged at this cabinet 2 front can slide up and down the sliding door 3 opening this vent cabinet 1 and the chain gearing driving this sliding door 3 to slide up and down;
This chain gearing comprises the first drive 4 and the second drive 5 being arranged at this cabinet 2 upper wall, this the first drive 4 and this second drive 5 are provided with the driving chain 6 coordinated with this first drive 4 and the second drive 5 respectively, this driving chain 6 one end is fixedly connected with this sliding door 3, this driving chain 6 other end end is provided with counterweight box 7, this cabinet 2 upper wall is also provided with driving motor, this driving motor is provided with power transmission shaft 8, and this power transmission shaft 8 arranges with this first drive 4 is coaxial and drives this first drive 4 to rotate by this power transmission shaft 8;
This vent cabinet 1 cabinet 2 upper wall is also provided with ventilator cowling 9, is provided with the ventilating fan 10 relative with this ventilator cowling 9 position inside this ventilator cowling 9.
Concrete, be also provided with in this cabinet 2 as driving motor and ventilating fan 10 work the power supply of power supply, and control that driving motor rotates forward, reversion or close and switch that ventilating fan 10 opens or cuts out, therefore not to repeat here.
When using ventilation hoods for laboratories 1 of the present utility model, user controls the forward or reverse of the first drive 4 by the forward or reverse controlling driving motor, drive driving chain 6 to move by the first drive 4, then drive sliding up and down of sliding door 3 to realize closure or openness sliding door 3 by the movement of driving chain 6.User no longer needs manual operation to carry out closure or openness sliding door 3, achieves the effect of Automated condtrol, adds operating efficiency.Simultaneously by control ventilating fan 10 open and close the mobility increasing air in vent cabinet.
