Description

A kind of clamp for picking and placeing alcolhol burner

Technical field

A kind of clamp for picking and placeing alcolhol burner is the utility model is related to, belongs to euglycemic clamp field.

Background technology

Alcolhol burner is the heating tool using alcohol as fuel, for heating object, is widely used in chemistry, biology, medicine etc. Field.Smog will not be produced in alcolhol burner combustion process, therefore sterilizing can also be achieveed the purpose that by the calcination to apparatus.Again Because of the heat produced in alcolhol burner combustion process, may also be used for heating other experiment materials, heating-up temperature reaches 400- 1000℃。

Alcolhol burner is divided into hanging alcohol blast burner, sitting posture alcohol blast burner and conventional alcohol lamp as referred to herein.Laboratory etc. Generally most with glass material, it is mainly made of lamp pot, lamp neck, light-carrier canal, lamp holder and the crown top of burner, sees Fig. 1.

The application method of alcolhol burner, generally lights and is placed in brandreth, placing response vessel above brandreth, After use, then by alcolhol burner taken out between brandreth and reaction vessels.Due to being limited to the size specification of reaction vessels With the size specification of brandreth, the operating space that alcolhol burner can pick and place is narrow and small.The operating method of alcolhol burner is mostly free-hand at present Or take with gloves.Due to being equipped with alcohol in alcolhol burner lamp pot, slightly tilt alcohol will be spilt and.Moreover, reaction vessels All kinds of reaction liquids of interior splendid attire, are in the condition of high temperature after alcolhol burner heats.Operating personnel are when taking alcolhol burner, slightly not Look to encounter or even overturn these heated reaction vessels, cause high-temp liquid to be toppled over and sputter, can scald, operation of burning The hand of person, even arm, face position, it is serious to trigger fire, even explode.

Above-mentioned problem brings pain and security risk to operator, also brings problem of management to unit department, because This, there is an urgent need to research and develop a kind of instrument for picking and placeing alcolhol burner, to solve the above problems, excludes security risk, establishes safe Practise, experimental situation.

Utility model content

The purpose of this utility model is to solve the deficiencies in the prior art, there is provided a kind of clamp for picking and placeing alcolhol burner.This practicality New clamp, reduces the operating space that alcolhol burner picks and places, and avoids hand operation and is touched to testing article around alcolhol burner Hit, and can occur to come off from clamp when all directions tilt in alcolhol burner, safe ready is easy to operate, reduces Accident rate, reduces fire risk.

The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of clamp for picking and placeing alcolhol burner, including it is logical Cross the hinged short caliper for forming cross-like structure of axis nail and long caliper, the short caliper and alligator pliers body are located at the first plane It is interior；One end of the short caliper is bent to form the first clamping elbow, and the first clamping elbow is located in the second plane；The length Caliper is bent to form the second clamping elbow close to one end of the described first clamping elbow, and the second clamping elbow is flat positioned at the 3rd Face；Second plane and the 3rd plane are vertical with first plane, and second plane and the 3rd plane are parallel to each other；

The first clamping elbow is fastened in lamp pot and the junction of lamp neck of alcolhol burner, the second clamping elbow from The opposite direction of the first clamping elbow is fastened on the lamp pot of alcolhol burner.

The principle of the utility model is：

I, axis nail is used for fixing short caliper and long caliper, and makes long caliper and short caliper using axis nail as axle center, and opening and closing produce The rotation of certain angle, so that the operation for picking and placeing alcolhol burner is smoothed out.

II, first clamps elbow and the second clamping elbow is located at two planes parallel to each other respectively, forms ring up and down and holds The lamp neck for the alcolhol burner just put and the junction of lamp pot, the second clamping are held, fix, being gripped to state, the first clamping elbow for ring Elbow is used for ring and holds, fixes, gripping the lamp pot of the alcolhol burner just put, can realize ring hold, fix, grip alcolhol burner up and down not Same position, the left and right directions of fixed alcolhol burner, while formed in vertical direction opposite to grip force so that the alcolhol burner of gripping Above-below direction is fixed, so as to flexibly and comfortably pick and place alcolhol burner.

The short calipers of III, and long caliper are used for the whole clamp of operator's hand-held.
