Description

Technical Field

[0001] The utility model relates to the technical field of experimental appliances, and particularly relates to an iron stand. Background Art

[0002] An iron stand is composed of a base with a relatively large mass and an iron rod fixed to the iron base and perpendicular to the base. According to different experimental contents, additional instruments such as iron rings that can move up and down, flask clamps, burette clamps, and condenser clamps are often equipped.

[0003] The existing iron stand has a simple structure. The existing iron stand adjusts the height between the iron rings according to each experimental apparatus. The manual adjustment has a large error and requires multiple adjustments. The iron rings cannot fix experimental apparatuses such as alcohol lamps or large beakers with relatively large weight and volume. Only other experimental apparatuses that can be fixed by the iron rings can be moved to match the height of the alcohol lamp or large beaker, and the experimental operation is relatively inconvenient.

[0004] Therefore, it is very necessary to invent an iron stand to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an iron stand to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An iron stand includes a base. A groove is opened on the base. The inner wall of the groove is connected with a first motor. The output end of the first motor is connected with a bidirectional threaded rod. The other end of the bidirectional threaded rod is connected with the inner wall of the groove. Two first moving blocks are connected to the outer wall of the bidirectional threaded rod. A chute is opened at the bottom of the groove. The first moving block is connected with the chute. The top of each first moving block is connected with a first rotating frame. A support rod is connected to each first rotating frame by a rotating shaft. The two support rods adopt a scissor structure. The other end of the support rod is connected with a second rotating frame by a rotating shaft. The top of the second rotating frame is connected with a placement plate. An iron rod is connected to the top of the base. Two columns are connected to the top of the base. An installation groove is opened in the column. A threaded rod is connected to the inner wall of the installation groove. A second moving block is connected to the outer wall of the threaded rod. A second motor is connected to the top of each column. The threaded rod passes through the column and is connected with the output end of the second motor. An extension rod is connected to one side of the second moving block. The extension rod is connected with the iron rod. A sliding port corresponding to the iron rod is opened on the extension rod. A sleeve is connected to one side of the extension rod. A threaded port is opened at the top of the sleeve. A locking bolt is connected at the threaded port.

The experimental equipment with a large volume and mass can be placed on the placing plate. When the second motor works, it drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod drives the first moving block to move, so that the first rotating frame drives the placing plate to rise and fall through the support rod and the second rotating frame, driving the experimental equipment with a large volume or mass to rise and fall together, which can reduce the error of manually adjusting the height of the iron ring, without the need for multiple adjustments. When it is not necessary to fix the experimental equipment with a large volume or mass, the height of this kind of experimental equipment can be adjusted, which provides convenience for the normal operation of the experiment.
