Abstract
The utility model relates to a telescopic foldable iron support. The telescopic foldable iron support comprises a base, a support column, a support column fixing nut, a rack bolt, a sleeve, a folding rod, a hoop type iron clamp, non-return springs, a hollow stretching rod and a solid stretching rod; the telescopic foldable iron support is characterized in that the support column is installed on the base, the sleeve is arranged on the folding rod, the inner diameter of the sleeve is the same as the outer diameters of the folding rod and the support column, after the folding rod is erected, half of the sleeve downwards covers the support column so as to form a stable support, the non-return springs are arranged at the lower ends of the hollow stretching rod and the solid stretching rod, spring holes are formed in the upper ends of the folding rod and the hollow stretching rod, and when a stretching support reaches the spring hole, the non-return spring returns back into the spring hole, so that the stretching support becomes a stationary support; two semicircles are arranged at one end of the hoop type iron clamp, one of the semicircles is movable, one end of the movable semicircle is connected with the hoop type iron clamp through a hook, the other end of the movable semicircle is locked through a screw rod, common iron clamps can be applied by the solid stretching rod, while the hollow stretching rod and the folding rod are hollow and cannot bear the pressure of common iron clamp screw rods, thus only using the special hoop type iron clamps.
Description
Technical field
Telescopic folding iron stand relates to the support of a kind of physics, chemical experiment device, belongs to the experiment teaching instrument in school science, Middle School Physics and chemistry subject.
Background technology
In school science, Middle School Physics and chemical experiment teaching instrument, existing iron stand is comprised of a base and a long pillar, tested the rear collection that is unfavorable for especially, take up room most, be not covered up and exist potential safety hazard, a so high support on laboratory table, pupil is active, robbing and going to play, can prick people unavoidably, sometimes will arrive outside and take part in game and be not easy to and carry.For solving the above-mentioned problems in the prior art, specially design and make telescopic folding iron stand.
Summary of the invention
The utility model telescopic folding iron stand, comprise base, pillar, pillar hold-down nut, support bracket bolt, sleeve, folding rod, hoop formula iron clamp, check spring, hollow stretching bar and solid stretching bar etc., it is characterized in that: pillar is arranged on base, folding rod is provided with sleeve, the internal diameter of sleeve is identical with the external diameter of pillar and folding rod, folding rod vertically after, half of sleeve is enclosed within downwards becomes stable support on pillar; Hollow stretching bar and solid stretching bar lower end are provided with check spring, and folding rod and hollow stretching bar upper end are provided with spring eye, and stretching support is during to spring eye position, and check spring springs into spring eye, becomes a fixed support; One end of hoop formula iron clamp is provided with two and half circles, it is movable wherein having one and half circles, one end is connected with hoop formula iron clamp with hook, the other end is locked with screw rod, tightly bind round on hollow support, on solid stretching bar, can use general iron clamp, hollow stretching bar and folding rod are hollow, can't stand the pressure of general iron clamp screw rod, can only use special-purpose hoop formula iron clamp.
Accompanying drawing explanation
Accompanying drawing 1 is telescopic folding iron stand installation drawing.By sequence number: 1. base, 2. pillar hold-down nut, 3. support bracket bolt, 4. sleeve, 5. folding rod, 6. hoop formula iron clamp, 7. check spring, 8. hollow stretching bar, 9. check spring, 10. solid stretching bar, 11. general iron clamps; Fig. 2 is that telescopic folding iron stand shrinks the design sketch after folding.
The specific embodiment
Telescopic folding iron stand, comprise base, pillar, pillar hold-down nut, support bracket bolt, sleeve, folding rod, hoop formula iron clamp, check spring, hollow stretching bar and solid stretching bar etc., it is characterized in that: pillar is arranged on base (1), with nut, fix, folding rod (5) is provided with sleeve (4), and the internal diameter of sleeve equates with the external diameter of pillar and folding rod, by folding rod vertically and when pillar is in alignment, sleeve is enclosed within downwards on pillar, and folding rod is fixed to as stable support; Hollow stretching bar (8) is being overlapped in folding rod the inside, solid stretching bar (10) is being overlapped in hollow stretching bar the inside, form collapsible, to stretch and a shrink travel(l)ing rest, hollow, solid stretching bar lower end is provided with check spring (9), folding rod and hollow stretching bar upper end are provided with spring eye, stretching support before experiment, when being stretched to spring eye position, check spring springs into spring eye, and become a fixed support, be equivalent to a common iron stand; One end of hoop formula iron clamp (6) is provided with two and half circles, and it is movable wherein having one and half circles, and one end is with being hooked on hoop formula iron clamp, and the other end is locked with screw rod, tightly binds round on hollow support.On solid stretching bar, can use general iron clamp, hollow stretching bar and folding rod are hollow, can't stand the pressure of general iron clamp screw rod, can only use special-purpose hoop formula iron clamp.
