Height-adjustable combined type iron stand

Abstract

The invention discloses a height-adjustable combined type iron stand which comprises a base, a strut and a clamping device, wherein the strut is fixedly arranged on the upper portion of the base, the clamping device is arranged on one side of the strut and is movably connected with the strut, a sustaining screw is arranged at the position where the champing device is movably connected with the strut, the strut comprises a sleeve and a stretchy rod, an adjusting bolt is arranged on one side of the sleeve, the lower end of the stretchy rod stretches into the sleeve, a guiding groove is formed in one side of the stretchy rod in the longitudinal length direction of the stretchy rod, the tail end of the adjusting bolt penetrates through the wall of the sleeve to stretch into the guiding groove, the clamping device comprises a main clamping device and an auxiliary clamping device, the auxiliary clamping device is arranged on the upper portion of the main clamping device, and the main clamping device and the auxiliary clamping device are connected through a sliding device. According to the height-adjustable combined type iron stand, the height of the strut arranged on the upper portion of the iron stand can be adjusted freely, and two test tubes can be heated at the same time as needed. The height-adjustable combined type iron stand has the advantaged of being reasonable in structural design, convenient to use and the like.

Description

technical field [0001] The invention relates to a chemical experiment equipment, in particular to a height-adjustable combined iron stand. Background technique [0002] The iron stand is a kind of experimental equipment that is often used in chemical experiments. It is usually used to fix and clamp the test tube in the process of heating the test tube. However, the existing iron stand has the following deficiencies: one is the conventional iron stand. The rack can only realize the fixed heating of a single test tube. When two test tubes need to be heated at the same time, two iron racks need to be used at the same time. In this way, it is inconvenient to use the traditional iron rack to heat more than two test tubes at the same time. The second is that the height of the pillars of the currently used iron frame platform for fixing the clamping device is generally non-adjustable. When the height of the clamping device needs to be adjusted, it can only be adjusted by adjusting ...

In this way, it is inconvenient to use the traditional iron rack to heat more than two test tubes at the same time. The second is that the height of the pillars of the currently used iron frame platform for fixing the clamping device is generally non-adjustable. When the height of the clamping device needs to be adjusted, it can only be adjusted by adjusting the relative position of the clamping device on the pillar. Adjust the height of the clamping device, there is a problem of inconvenient adjustment
