Description
(1) technical field
The utility model relates to chemical experiment field, particularly one lifting iron stand.
(2) background technology
The problem that we run in laboratory at ordinary times mainly contains four:
The iron stand that laboratory is commonly used mainly is made up of base, iron, iron ring, iron clamp, its weak point is in use owing to only having an iron, generally only can install an apparatus, slightly complicated experiment, often needs multiple iron stand split to use.
Also commonly use test tube and rack for test tube in chemical experiment, if tested, teacher needs to prepare a lot of thing, inconvenient, and, for the comparative experiments of branched test tube, be placed on student on rack for test tube and be not easy observe phenomena.
Some experiment needs to use alcolhol burner heating, often needs chock block or uses tripod.Take up room, unsightly, prepare also more inconvenient.
If the device of experiment is many, install more complicated, a lot of student controls the distance of bad round-bottomed flask and alcolhol burner, near or far away, causes repeated removal to repeat to install, wastes a lot of time, increase the probability of instrument damage.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides a kind of lifting iron stand simple to operate, easy to use.
The utility model is achieved by the following technical solution:
A kind of lifting iron stand, comprise base and bracing frame, on support frame as described above, cover has lowering or hoisting gear, lowering or hoisting gear is provided with set 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 comprises 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.
Described lifting platform is also provided with by the fixing clamper of securing member, described clamper comprises the master link be flexibly connected with lifting platform, the outer end of described master link is provided with fixed head, on described master link, cover has portable plate, described fixed head is parallel with portable plate, is provided with adjusting bolt between described fixed head and portable plate.
The inside bending in lower end of described fixed head and portable plate.
The beneficial effects of the utility model are:
The utility model utilizes gear drive principle, regulates the height of lifting platform by knob, reaches overall and raises or reduce the object of finely tuning laboratory apparatus, need not repeated removal and installation again, thus has saved the time of student, also reduces the probability of instrument damage; Also be applicable to assemble the more experiment of instrument simultaneously, can integral elevating, fine setting is got up easily; Its make simple, cost is low, practical, lecture experiment and student experimenting all can use, can spread.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the plan structure schematic diagram of test tube holder.
In figure, 1 base, 2 bracing frames, 3 tooth bars, 4 lifting platforms, 5 set bolts, 6 gears, 7 knobs, 8 test tube holders, 9 test tube holes, 10 securing members, 11 clampers, 12 master links, 13 fixed heads, 14 portable plates, 15 adjusting bolts.
(5) detailed description of the invention
