Embodiment Construction

[0012] Such as figure 1 As shown, the design consists of a heating mantle 1, a housing 2, a partition 3, a spring 4, a shaft 5, a nut 6, a knob 7, a screw 8, a fine-tuning knob 9, a nail 10, and a support block 11. Put the whole device under the object to be heated, adjust the knob 7 so that the knob 7 is down, the pressure of the knob 7 on the right end of the shaft 5 will be reduced, thereby reducing the pressure of the partition 3 on the spring 4, and the spring 4 will spring up quickly , make the resistance wire on the heating mantle 1 close to the object to be heated, turn the fine-tuning knob 9 to reduce the part of the screw 8 in the fine-tuning knob 9, and the resistance wire of the electric heating mantle 1 will be closer to the object to be heated, and at the same time it will not be in contact with When the object to be heated is in contact, when a certain temperature is to be kept constant, the temperature of the object to be heated is lowered by adjusting the volt...

Abstract

The invention relates to an electric heating device based on a height adjusting structure, and overcomes the disadvantage that the height of an electric heating sleeve cannot be adjusted in the priorart. The electric heating device is composed of an electric heating sleeve, a shell, a clapboard, springs, a shaft, a nut, a knob, screws, fine tuning knobs, a nail and a support block; the shell is cylindrical; furthermore, the side wall of the shell has a nick; the shell is just below the electric heating sleeve; the clapboard, the springs and the support block are in the shell; the springs arefixed at the bottom of the shell; the clapboard is rectangular; furthermore, the upper and lower ends of the clapboard are separately connected with the electric heating sleeve and the springs; the shaft is shaped as a slope; the support block is a rectangular frame structure; the shaft passes through the middle part of the support block, and is fixed on the support block by the nail; the left endof the shaft is connected with the clapboard; the nut is fixed on the shell; the lower end of the knob is rectangular; the upper end of the knob is cylindrical; a thread is arranged at the upper endof the knob; the knob passes through the centre of the nut; two same screws are separately arranged at the bottom of the shell; the lower ends of the screws are separately penetrated in the two same fine tuning knobs; the fine tuning knobs are cylindrical; and furthermore, threads are arranged in the fine tuning knobs.

Description

technical field [0001] The invention relates to experimental equipment, in particular to an electric heating device based on a height adjustment structure. Background technique [0002] The height of the existing electric heating mantle is constant. When heating a higher object, it is necessary to place the object under the electric heating mantle. When the heating is stopped, even if the electric heating mantle is turned off, the residual heat of the electric heating mantle will continue to heat the object. It will be very difficult to remove the heating mantle when there is an object under it. Contents of the invention [0003] The purpose of this design is to overcome the defect that the height of the electric heating jacket cannot be adjusted in the prior art, and provide an electric heating device based on a height adjustment structure [0004] Technical solutions: [0005] This design is composed of electric heating mantle, shell, partition, spring, shaft, nut, kno...
