Abstract
The utility model discloses a rotary endless regulating bracket for the height of alcohol lamps, consisting of a lamp stand (1) and a pedestal (2), wherein, the pedestal (2) is of a frustum shape, while the lamp stand (1) is of a circular disc shape, and an alcohol lamp placing groove (3) is arranged on an upper panel of the lamp stand (1). The utility model is characterized in that: a rotary lifting rod (4) is arranged between the lamp stand (1) and the pedestal (2); the upper end of the rotary lifting rod (4) is fixed with the middle part of the bottom plate surface of the lamp stand (1); the upper part of the rotary lifting rod (4) is provided with a hand-hold rotating ring (5). The rotary endless regulating bracket for the height of alcohol lamps is simple in structure, convenient to use, easy to carry, stable in alcohol lamp placement, and capable of adapting to the regulation and fixation at any height.
Description
Technical field
The utility model relates to a kind of improvement of used alcolhol burner support in chemical experiment, the electrodeless adjusting support of specifically a kind of rotary alcolhol burner height.
Background technology
In chemistry experiment, and in the experiment of chemical plant and hospital, often adopt alcolhol burner to heat, in the operation, the test tube or the beaker that fill medicine are fixed on the iron stand, when heating with alcolhol burner, the placement of its alcolhol burner highly needs to regulate, so that the alcolhol burner flame location reaches requirement of experiment with the distance that heats test tube or beaker, this excursion is between 5-15cm, at present, the method for regulating the alcolhol burner height is the method that adopts at alcolhol burner bottom chock piece, because the thickness of institute's chock piece is fixed, so the height of pad does not reach requirement sometimes, at this moment, sometimes with things such as books bed hedgehopping again, the deficiency that adopts wooden unit to regulate alcolhol burner height method is: inconvenient operation, the alcolhol burner instability, regulating height can not adjust on demand.
Summary of the invention
The purpose of this utility model is to provide a kind of not only simple in structure but also easy to operate, alcolhol burner stable, height can be adjusted arbitrarily electrodeless adjusting support of rotary alcolhol burner height.
For reaching above purpose, the technical scheme that the utility model adopted is: the electrodeless adjusting support of this rotary alcolhol burner height, constitute by lamp holder, base, base is a frustum, the lamp holder is discoid, on the upper face of lamp holder, establish alcolhol burner and place groove, it is characterized in that between supporting plate and base, establishing the rotary lifting bar, the upper end of rotary lifting bar and lamp butt plate face middle part are fixing, establish hand-held swivel becket on the top of rotary lifting bar, by the rotation of hand-held swivel becket, implement the lifting of rotary lifting bar, thereby realize the adjusting of alcolhol burner height.The utility model is also implemented by following measure: described rotary lifting bar is a screw rod, the lower end is rotated in the barrel, the external screw thread of rotary lifting bar matches with the internal thread of barrel, the tube that is threaded is established at base plate face middle part in the lamp holder, and the upper end of rotary lifting bar is rotated in the tube that is threaded of lamp butt plate face; The lower end of barrel is fixed on the upper face middle part of base, and the upper end of the tube that is threaded is fixed on the middle part of lamp holder lower face; Described base is a solid, and the center of gravity of support is moved down, and increases the stability of support; The shape that the alcolhol burner of described lamp holder upper face is placed groove is consistent with the shape of alcolhol burner bottom, and it is stable that alcolhol burner is placed; On the outer wall of hand-held swivel becket, be provided with the annular knurl line, to increase hand-held resistance.
The beneficial effects of the utility model are: simple in structure, easy to use, be easy to carry and alcolhol burner is placed stablely, the adjusting that can adapt to arbitrary height is fixed.
