Abstract

The utility model provides a gas collection apparatus, which relates to a rack used for placing a gas collecting bottle when draining and air collection are carried out in a chemical laboratory. The utility model can be made into steady racks (3) of various models according to the sizes of the gas collecting bottle necks which are needed to be fixed. Due to the additional arrangement of the steady racks (2) and a hook (3), operators have no need of handing the gas collecting bottle or supporting an airway, and the experiment can be normally carried out. The operators have two hands free to do the works of looking after a generator, replacing the gas collecting bottle, treating tail gas, etc. The utility model can make the experiment be well done and prevent experiment accidents from occurring.

Description

The gas collecting frame

The utility model relates to a kind of chemical laboratory when collecting gas with drainage, puts the shelf of putting gas bottle, and the fixation problem of gas bottle, wireway.

Chemical laboratory is used for the support that drainage is collected gas, the device of no stable set gas cylinder and wireway at present.The operator has to hand steered a gas bottle (preventing to topple over) when collecting gas, and proficiency is held wireway (preventing that the air guide mouth of pipe from departing from the inner space of gas bottle).Because of all accounting for, two hands can't take the generator that producing gas and other into account.If the replacing gas bottle, the one, allow gas emptying in the generator in vain, cause waste; As then causing environmental pollution for toxic gas; The 2nd, please other people help in addition.This is an inconvenience how! Particularly glass flume chord frame does not have yet, and when collecting gas, the operator is busy especially.

The utility model is on original collecting frame, sets up steady rest and fixes gas bottle, sets up suspension hook and fixes wireway.Purpose is that operator's two hands are available, and has looked after generator, reactant, replacing gas bottle by easy stages and has in time handled a job such as tail gas well, prevents the generation of experiment accident, carries out experiment.

Structure of the present utility model is seen accompanying drawing: Fig. 1 is a cutaway view, and Fig. 2 is a vertical view.

[1] support, [2] steady rest, [3] suspension hook

The function of the utility model fixed set gas cylinder and wireway is finished respectively by steady rest and suspension hook.Two socles of steady rest are inserted in two apertures on the support, and the annulus of socle upper shed stretches to the circular hole of support, and the opening of two annulus is relative on the support.Annulus is slightly larger than about gas bottle eck 2mm.A side that gives on circular hole at support has a suspension hook that is 60 ° of angles.

Because the utility model is reasonable in design, has set up steady rest on support, adopted the slightly flexible plastic production annulus of tool again, slightly firmly the gas collection bottleneck is snapped in the annulus from opening part during use, stand upside down on support.Gas bottle is not chosen holding up the vertical direction that can both remain handstand, the water in the reason gas bottle is not discharged by gas and is lightened, and suffered buoyancy falls partially greater than gravity.After stretching into wireway in the gas bottle, wireway is put into suspension hook, just can keep wireway can not come off the inner space of gas bottle, also need not to remove supportting wireway with hand.Because operator's two hands are empty, just can change gas bottle timely, take care of the good generator that is producing gas, perhaps handle tail gas or the like work well.Prevent pollution, avoided waste.

The utility model raw material (igelite) is easy to get, and cost is low, and technology is simple, is easy to make, and small investment is subjected to the welcome of experiment operator deeply.

Experimental example:

Make as scheming the shape of [1] with igelite.The thick 2mm of support, wide 60mm, the long 70mm of two waists, the long 176mm in the end, respectively there is hook at two ends, and two φ are respectively arranged is the circular hole of 1.4mm at mid point 40mm place the end of apart from, circular hole is by two end distance circumference 20mm places, and it is the 5mm small sircle hole that two φ at a distance of 25mm are arranged, and makes to insert the usefulness of steady rest pin.The high 15mm of steady rest pin, φ are 5mm, and there is the annulus of an opening on the top, and annulus φ is 35mm, and end is the inclined-plane, ring width 10mm, thick 2mm, the wide 25mm of breach.One long 10mm is arranged on the limit that the bracket bottom lower surface and the circular hole heart face toward, wide 5mm, thick 2mm curves the suspension hook at 60 ° of angles.

Claims

1, a kind of gas collecting frame, by collecting frame [1], steady rest [2], suspension hook [3], etc. formation, it is characterized in that upright on the support steady rest [2] being arranged, have on the bipod of steady rest and stretch to an annulus of putting up opening shape, two annulus openings are relative.

2, gas collecting frame according to claim 1 is characterized in that the suspension hook [3] at support two ends is 60 ° of angles.
