Description
Technical field
Chemical experiment appliance technology is the utility model is related to, specially a kind of chemical experiment heating frame.
Background technology
In high school chemical experiment, it often may require that and various reagents heated, it is complete by beaker or test tube during heating
The carrying of paired reagent, then by a heating frame, but heating frame in heating process all the time to the one of beaker or test tube
Individual point is heated, and heating is more uneven, it is easy to is caused beaker or test tube to ftracture, is caused danger, and needs to carry out uniformly
During heating, test tube or beaker can only be held, uniformly heating is completed by hand shake, larger potential safety hazard be present.
Utility model content
The technical problems to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of chemical experiment heating
Frame.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：A kind of chemical experiment, which is used, to be added
Hot frame, including base and cross bar, two elevating levers are installed with the base, and be provided with cross bar on two elevating levers,
Cross bar is fixedly connected with the link position of elevating lever by trip bolt, and the centre position of the base is arranged to alcolhol burner placement
Area, alcolhol burner rest area are arranged above being provided with magnet for beaker rest area, the left end of the cross bar, pressing from both sides among magnet
Hold graduated scale, the contact portion of magnet and graduated scale is provided with rubber blanket, and the right-hand member of cross bar is provided with draw ring, in draw ring
Meta, which installs, is set to flask rest area.
Preferably, the elevating lever is evenly arranged with fixing threaded hole from top to bottom.
Preferably, it is mounted on rubber block at left and right sides of the beaker rest area.
Preferably, it is provided with limited block at left and right sides of the inside of the draw ring.
Preferably, it is provided with external screw thread on the draw ring.
The beneficial effect that the utility model is reached is：The utility model to reagent when heating, it is only necessary to by wine
Smart lamp is placed in predetermined region, eccentric setting between the wick and cross bar of alcolhol burner, and when adjusting cross bar, wick carries out annulus
It is mobile, the uniform heating to beaker or flask is completed, the risky operation step of hand-held heating is instead of, can quickly realize to reagent
Uniform heating, operation it is safer.
