Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a lifting iron frame platform. Background Technology

[0002] Chemical experiments are a series of operations that involve observing, measuring, and analyzing chemical reactions and the properties of substances to study chemical phenomena. An experimental iron stand is a tool used to support experimental equipment and assist personnel in conducting experiments. The iron stand can stably support various experimental instruments, such as flasks, test tubes, and burettes, ensuring the safety and accuracy of the experimental process.

[0003] A search revealed a laboratory iron stand in patent document CN211586689U. It includes a base, a support column vertically fixed to the base, and flask clamps and iron rings mounted on the support column. At each of the four corners of the base's bottom are a base fixing device for securing the base to the work surface. This base fixing device includes a support base fixed to the base, a suction cup mounted on the bottom of the support base, and a suction cup lever for operating the suction cup. This invention, by assembling base fixing devices at the four corners of the iron stand base, achieves adsorption and fixation between the iron stand base and the work surface, effectively solving the problem of damage to experimental instruments caused by accidental collisions or loads on the iron stand during experimental teaching, while ensuring the safety of experimental teaching.

[0004] Regarding the aforementioned related technologies, the inventor believes that the following defects exist:

[0005] 1. The above device is not convenient to adjust the height of the experimental platform according to the user's needs and the operator's height. Therefore, it may be inconvenient for operators with mismatched heights to use the device for experiments.

[0006] 2. Furthermore, the above-mentioned device can only roughly adjust the height of the test container, making it inconvenient to fine-tune the height of the test container, and it is impossible to intuitively observe the specific height of the test container. Therefore, it is necessary to provide a new lifting iron frame platform to solve the above-mentioned technical problems. Utility Model Content

[0010] As a further improvement to the above solution, a protective coating is provided on the upper surface of the support platform, and the material of the protective coating is polypropylene.

[0011] The above technical solution can improve the acid and alkali resistance of the upper surface of the support platform, thereby extending the service life of the support platform.

The gear is located inside the middle position of the lifting device, and the gear meshes with the rack.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model allows the adjusting screw to rotate inside the second connecting rod by rotating the handwheel, thereby moving the second connecting rod inside the other end of the two sets of second connecting plates and adjusting the height of the two sets of scissor support frames. This allows for the adjustment of the overall height of the support platform and the adjusting structure. This design enables the operator to adjust the support platform to a suitable height for use, effectively improving the practicality of the equipment.

[0020] Furthermore, this invention allows the gear and rack to mesh by rotating the adjusting rod, thereby enabling the lifting device to move slowly on the outer surface of the support rod. Rotating the fixing bolt allows one end of it to abut against the outer surface of one side of the support rod, thus fixing the height of the lifting device on the outer surface of the support rod. This design allows the operator to fine-tune the height of the lifting device by rotating the adjusting rod, thereby improving the rigor of the experimental process to a certain extent.

The other end of the adjusting screw 18 is inserted into the interior of the stabilizing seat 111.

[0030] The above technical solution enables the height of the support platform 110 to be adjusted according to user needs and the operator's height.

[0031] As a further improvement to the above solution, a protective coating is provided on the upper surface of the support platform 110, and the material of the protective coating is polypropylene.

[0032] The above technical solution can provide acid and alkali resistance to the upper surface of the support platform 110, thereby extending the service life of the support platform 110.

[0033] As a further improvement to the above scheme, a scale line 22 is provided on the surface of one side of the support rod 21, the rack 23 is fixedly connected to the surface of the other side of the support rod 21, the lifting device 24 is sleeved on the outer surface of the support rod 21, and a fixing bolt 25 is connected to the internal thread of the outer surface of one end of the lifting device 24, and one end of the fixing bolt 25 abuts against the surface of one side of the support rod 21.

[0039] The implementation principle of a lifting iron frame platform in this application embodiment is as follows:

Then, the second connecting rod 15 will move inside the other end of the two sets of second connecting plates 17, and then the height of the two sets of scissor support frames 13 will be adjusted. Thus, the overall height of the support platform 110 and the adjusting structure 2 can be adjusted.

Then, the gear 27 meshes with the rack 23 during rotation, which can drive the lifting device 24 to move slowly on the outer surface of the support rod 21. At this time, the height of the lifting device 24 on the outer surface of the support rod 21 can be observed through the scale line 22. After the lifting device 24 is adjusted to a suitable height, rotate the fixing bolt 25 so that one end is pressed against the outer surface of one side of the support rod 21.
