Description
(1)
Technical field
The present invention relates to chemical experiment field, lift iron stand particularly to one.
(2)
Background technology
The problem that we run at laboratory at ordinary times mainly has four:
The iron stand that laboratory is conventional is mainly made up of base, iron, iron ring, iron clamp, its weak point in use is due to only one iron, typically it is only capable of installing an apparatus, slightly complicated experiment, generally requires multiple iron stand split and use.
Also commonly using test tube and test tube rack in chemical experiment, if tested, teacher needs to prepare a lot of thing, it has not been convenient to, and, for the comparative experiments of branched test tube, it is placed on student on test tube rack and is not easy to observe phenomenon.
Some experiment needs to use alcohol burner heating, generally requires chock block or uses spider.Taking up room, unsightly, preparation is got up the most inconvenient.
If the device of experiment is many, installing more complicated, a lot of students control the distance of bad round-bottomed flask and alcohol burner, near or remote, cause repeated removal to repeat to install, waste a lot of time, increase the probability of instrument damage.

Summary of the invention
The present invention is in order to make up the defect of prior art, it is provided that a kind of lifting iron stand simple to operate, easy to use.
The present invention is achieved through the following technical solutions:
A kind of lifting iron stand, including base and bracing frame, lowering or hoisting gear it is cased with on support frame as described above, lowering or hoisting gear is provided with fixing bolt, it is characterized in that: support frame as described above is provided with the tooth bar parallel with bracing frame, described lowering or hoisting gear also includes lifting platform, is provided with and tooth bar meshed gears in described lifting platform, described lifting platform is provided with some test tube holders, and described test tube holder is provided with test tube hole and securing member.
The clamper fixing by securing member it is additionally provided with on described lifting platform, described clamper includes the master link being flexibly connected with lifting platform, the outer end of described master link is provided with fixed plate, it is cased with portable plate on described master link, described fixed plate is parallel with portable plate, is provided with regulation bolt between described fixed plate and portable plate.
The inside bending in lower end of described fixed plate and portable plate.
The invention has the beneficial effects as follows:
The present invention utilizes gear drive principle, by the height of knob regulation lifting platform, reaches entirety and the purpose of finely tuning experimental apparatus is raised and lowered, it is not necessary to repeats dismounting and installs, thus having saved the time of student, also reducing the probability of instrument damage；Being simultaneously applicable to assemble the experiment that instrument is more, it is possible to integral elevating, fine setting is got up easily；It makes simple, low cost, practical, lecture experiment and student experimenting all can use, can spread.
