Description
Technical field
The utility model relates to a kind of iron stand, especially a kind of novel retractable iron stand.
Background technology
In chemical experiment, iron stand is absolutely necessary the same experiment equipment, the support arm of conventional iron pallet is all non-telescoping, conveniently the operation notification number of experimenter is that the utility model patent of CN204469736U discloses the collapsible simple and easy iron stand in a kind of laboratory, notification number is that the utility model patent of CN101518750 discloses a kind of telescopic foldable iron support stand, although above two kinds of devices all achieve the Telescopic of iron stand support arm, but still have the following disadvantages in practical operation: 1, first need positioner to unclamp when adjusting the height of support arm, then again positioner is locked after adjusting height, be not only the trouble that operates like this, but also be difficult to carry out trickle adjustment to the height of support arm, particularly when heating test tube or beaker, be difficult to the height by adjusting support arm, guarantee there is suitable distance between alcolhol burner and test tube or beaker, 2, when carrying out some experiment, iron stand needs to clamp multiple test tube or beaker, but existing iron stand is not only difficult to the requirement meeting the multiple test tube of clamping, and the test tube clamped also is difficult to adjust its angle, thus add the difficulty of experiment.
Summary of the invention
Technical assignment of the present utility model is for above the deficiencies in the prior art, and provides a kind of novel retractable iron stand.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel retractable iron stand, comprise base, support arm and test tube clamp, wherein said support arm is combined by some joint support bars, the lower semisection of described support bar is screw rod upper semisection is sleeve, locating hole is provided with in described screw rod bottom, blind hole is provided with in described sleeve, backstay is provided with at described blind via bottom, by coordinating of backstay and locating hole, the screw portion being positioned at upper support bar is made to be positioned at the blind hole vertical telescopic of supported underneath bar, regulating sleeve is fixed with at described supporting bar top, the screw thread that can coordinate with described screw rod is provided with in described regulating sleeve, regulating sleeve can freely rotate, the flexible of support bar just can be controlled like this when rotating regulating sleeve, axle sleeve is fixed with at described support bar upper semisection, described test tube clamp is positioned on described axle sleeve, the position of test tube clamp is adjusted by rotary axle box, thus the carrying out of convenient experiment.
Advantage of the present utility model: 1, the flexible of support bar can be adjusted by rotating regulating sleeve when testing, so not only handled easily, but also trickle adjustment can be carried out to the distance of support bar support, thus ensure that there is suitable distance between alcolhol burner and test tube or beaker, thus improve the effect of experiment; 2, can experimental demand, add or reduce support bar joint number, so just can clamp multiple test tube or beaker on same iron stand, the position of test tube clamp on support bar can also be adjusted by rotary axle box simultaneously, thus the carrying out of convenient experiment, alleviate the difficulty of experiment.

Fig. 2 is the connection diagram between the utility model support bar.
Fig. 3 is the utility model locating hole and backstay connection diagram.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described below.
As shown in the figure, a kind of novel retractable iron stand, comprise base 1, support arm 2 and test tube clamp 9, wherein said support arm 2 is combined by some joint support bars 21, just experimental demand can add or reduce the joint number of support bar 21 when testing like this, the lower semisection of described support bar 21 is screw rod 3, upper semisection is sleeve 4, locating hole is provided with in described screw rod 3 bottom, blind hole 7 is provided with in described sleeve 4, backstay 8 is provided with bottom described blind hole 7, by coordinating of backstay 8 and locating hole, screw rod 3 part being positioned at upper support bar 21 is made to be positioned at blind hole 7 vertical telescopic of supported underneath bar 21, regulating sleeve 6 is fixed with on described support bar 21 top, the screw thread that can coordinate with described screw rod 3 is provided with in described regulating sleeve 6, the flexible of support bar 21 just can be controlled in use by rotating regulating sleeve 6, axle sleeve 5 is fixed with at described support bar 21 upper semisection, described test tube clamp 9 is positioned on described axle sleeve 5, the position of test tube clamp 9 is adjusted by rotary axle box 5, thus the carrying out of convenient experiment.
Its operation principle is: because be connect together between two support bars 21, and on each joint support bar 21, be all provided with test tube clamp 9, so experimental demand the joint number of support bar 21 can be added arbitrarily when testing, normally carrying out of experiment is guaranteed with this, the position of screw rod 3 in blind hole 7 can be adjusted by rotating regulating sleeve 6 in experimentation, thus play the flexible object of control and regulation bar 21, when adjusting support bar 21 position, because there be coordinating of backstay 8 and locating hole, so screw rod 3 can only move vertically in blind hole 7, thus the perfect telescopic effect of support bar 21, simultaneously because test tube clamp 9 is arranged on axle sleeve 5, so just can be changed the position of test tube clamp 9 by rotary axle box 5, thus the position relationship between each laboratory apparatus of convenient adjustment, ensure that normally carrying out of experiment.
