Description
Technical field
The utility model relates to the chemistry teaching apparatus, is specifically related to the instrument lifting platform that uses in a kind of chemical experiment teaching.
Background technology
At present, still do not have special instrument lifting platform in the chemical laboratory of most schools and be used to go up and down alcolhol burner, beaker, conical flask etc., the experiment teacher relies on backing plate to change the height of instrument.And rely on backing plate not only complex operation, highly be not easy to regulate, and have certain danger-alcolhol burner, beaker, conical flask etc. to topple over easily.Therefore, need a kind of liftable of design, easy-operating instrument lifting platform, improve the ageing of experiment teacher work and student's study.
The utility model content
The technical problem that the utility model solved is to provide a kind of chemical experiment teaching to use the instrument lifting platform, thereby solves the problem in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of chemical experiment teaching is used the instrument lifting platform, comprises protective cover, and the bottom of said protective cover is provided with base, is installed with spring on the said base, and the free end of said spring is equipped with the shelf that is used to place instrument; Said protective cover is provided with at least two slideways that cooperatively interact, being removably connected on the slideway of said shelf.
As a kind of improvement, said protective cover is cylindric wire netting.
As a kind of further improvement, said slideway is four litter that are distributed on the cylindric wire netting.
As a kind of further improvement, said shelf is provided with the clamping head that cooperates with said litter, and said clamping head is provided with fastening bolt.
The utility model can be realized the height adjustment of shelf through the compression spring in use, utilizes clamping head that shelf is fixed on the litter again, thereby makes alcolhol burner, beaker, conical flask etc. be fixed in desired height.
Owing to adopted above structure, the utlity model has following beneficial effect:
The utility model is simple in structure, is easy to adjust the height of laboratory apparatus, effectively improves the ageing of experiment teacher work and student's study.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1. protective cover, 2. base, 3. spring, 4. alcolhol burner, 5. shelf, 6. litter, 7. clamping head, 8. fastening bolt.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of chemical experiment teaching is used the instrument lifting platform, comprises protective cover 1, and the bottom of said protective cover 1 is provided with base 2, is installed with spring 3 on the said base 2, and the free end of said spring 3 is equipped with the shelf 5 that is used to place alcolhol burner 4; Said protective cover 1 is cylindric wire netting; Cylindric wire netting is provided with at least two slideways that cooperatively interact; In the present embodiment; Slideway is four litter 6 that are distributed on the cylindric wire netting, and shelf 5 is provided with the clamping head 7 that cooperates with said litter 6, and said clamping head 7 is provided with fastening bolt 8.
The utility model can be realized the height adjustment of shelf 5 through compression spring 3 in use, utilizes clamping head 7 that shelf 5 is fixed on the litter 6 again, thereby makes alcolhol burner 4 be fixed in desired height.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
