Antiskid electric hot plate with heat insulation device

Abstract

The invention relates to a laboratory heating apparatus, and especially relates to an antiskid electric hot plate with a heat insulation device. The antiskid electric hot plate comprises a box body, a switch, an indication lamp, a heating surface, support legs, a heat insulation layer and an antiskid portion, the indication lamp is arranged at the left side of the box body, the switch is arranged in the middle position of the box body, the heat insulation layer is arranged under the support legs and is movably connected with the support legs, and the antiskid portion is uniformly distributed on the surface of the heating surface and is integrally formed together with the heating surface. The antiskid electric hot plate with the heat insulation device can prevent the damages of long time use to other articles; and the surface of the heating surface is provided with semi-circular projections for increasing the frictional force, so the use reliability of the electric hot plate is greatly improved.

Description

technical field [0001] The invention relates to a laboratory heating instrument, in particular to a non-slip electric heating plate with a heat insulating device. Background technique [0002] At present, laboratories or manufacturers often use electric heating plates to heat and digest test samples, boil them, steam acid, etc. They often place electric heating plates on the laboratory table, and the bottom of electric heating plates will always maintain a certain temperature after long-term use. If things go on like this, it will inevitably cause damage to the items under the equipment. In addition, the electric heating plate is often placed on the ground or table in the laboratory. Because the ground and the table are not flat enough, the electric heating plate often shakes during work, which may easily cause the test sample to fall from the electric heating plate. fall, which hinders the test process, so there is an urgent need to provide a non-slip electric heating plate...
