Description

Technical Field

[0001] The utility model belongs to the technical field of clean benches, and particularly relates to a clean bench that is convenient to use. Background Art

[0002] A purification workbench is a purification device that provides a locally highly clean working environment and has strong pass-through performance. It is widely used in teaching, medicine and health, electronics, bioengineering, scientific experiments, etc., and is one of the commonly used instruments in microbiology, tissue culture, and molecular biology experiments. The working principle of the purification workbench is that in a specific space of a clean environment, clean air flows in a set direction to form a highly clean working space.

[0003] The existing clean benches have the following problems during use:

[0004] 1. When the existing clean bench is in use, due to the fixed height of its overall structure, the height of the internal operation cavity is fixed, and it cannot be used by operators with different heights, which will cause inconvenience during overall use.

[0005] 2. When the existing clean bench is in use, its bottom is usually moved by universal wheels. However, after long-term use, the locking structure of the universal wheels is prone to failure, which will easily cause the universal wheels to not work properly, and thus the overall structure cannot be moved. For this reason, we propose a clean bench that is convenient to use. Content of the Utility Model

[0006] The purpose of the utility model is to provide a clean bench that is convenient to use, so as to solve the technical problems raised in the background art.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A clean bench that is convenient to use, including a main body. An operation cavity is opened inside the main body. A rotating rod is movably connected inside the main body. One end of the rotating rod is fixedly connected with a connecting mounting plate. One side of the connecting mounting plate is fixedly connected with a connecting rocker. Fixed mounting sleeve discs are symmetrically and fixedly sleeved on the outer side of the surface of the rotating rod. One side of the fixed mounting sleeve disc is fixedly connected with a first bevel gear. First positioning blocks are symmetrically and fixedly connected inside the main body.

[0028] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a convenient-to-use air purification workbench of the present utility model with reference to the accompanying drawings.

[0029] As Figures 1-5 shown, a convenient-to-use air purification workbench of the present utility model includes a main body 1. An operation cavity 2 is opened inside the main body 1. A rotating rod 3 is movably connected inside the main body 1. One end of the rotating rod 3 is fixedly connected to a connecting mounting plate 4. One side of the connecting mounting plate 4 is fixedly connected to a connecting rocker 5. Fixed mounting sleeve disks 6 are symmetrically and fixedly sleeved on the outer side of the surface of the rotating rod 3. One side of the fixed mounting sleeve disk 6 is fixedly connected to a first bevel gear 7. First positioning blocks 8 are symmetrically and fixedly connected to the inner side of the main body 1. An active threaded rod 9 is movably connected inside the first positioning block 8. The bottom of the active threaded rod 9 is fixedly connected to a second bevel gear 10. The top of the active threaded rod 9 is fixedly connected to a limiting top disk 12. A fixed limiting collar 13 is fixedly sleeved on the outer side of the surface of the active threaded rod 9. Second positioning blocks 11 are symmetrically and fixedly connected to the inner side of the main body 1. The inside of the second positioning block 11 and the outer side of the surface of the active threaded rod 9 are slidably fitted with each other. Guide rods are symmetrically arranged on the inner side of the operation cavity 2. A lifting operation table 14 is sleeved on the outer sides of the surfaces of the active threaded rod 9 and the guide rods.

[0030] The bottom end of the main body 1 is fixedly connected to universal wheels 15. The lower parts of both sides of the main body 1 are bolted with a connecting support fixing mechanism 16.

[0031] The lifting operation table 14 includes a threaded connection block 18. One end of the threaded connection block 18 is fixedly connected to an operation table body 17. Fixed guide blocks 19 are symmetrically arranged at the end of the operation table body 17. When the movable threaded rod 9 rotates, it is convenient for the threaded connection block 18 to move up and down on the outer surface of the movable threaded rod 9, so that the fixed guide block 19 can move on the outer surface of the guide rod, and the operation table body 17 can perform a stable lifting operation.

[0032] The threaded connection block 18 is connected to the movable threaded rod 9 by threads. The fixed guide block 19 and the guide rod are slidably fitted with each other, which is convenient for the threaded connection block 18 to move up and down on the outer surface of the movable threaded rod 9 as the movable threaded rod 9 rotates. At the same time, the fixed guide block 19 can move up and down on the outer surface of the guide rod, and the operation is convenient.

[0033] The first bevel gear 7 and the second bevel gear 10 are perpendicularly meshed and connected to each other. The second positioning block 11 and the limit top plate 12 and the fixed limit collar 13 are slidably fitted with each other, which is convenient for the first bevel gear 7 and the second bevel gear 10 to be stably transmitted. At the same time, the second positioning block 11 can be located between the limit top plate 12 and the fixed limit collar 13 to position the position of the movable threaded rod 9 and prevent the movable threaded rod 9 from being skewed.

[0034] The connection support and fixation mechanism 16 includes a connection mounting plate 20. Connection sleeve blocks 21 are symmetrically arranged on the surface of the connection mounting plate 20. An electric telescopic rod 22 is fixedly connected inside the connection sleeve block 21. The output end of the electric telescopic rod 22 is fixedly connected to a connection pressing support plate 23, which is convenient for the electric telescopic rod 22 to push the connection pressing support plate 23 downward, so that the connection pressing support plate 23 can contact the ground, thereby being able to support the whole, and the operation is convenient and fast.

[0035] Working principle of the convenient-to-use air purification workbench: During use, the whole can be moved to the required position through the universal wheels 15. Then, the electric telescopic rod 22 can push the connecting lower pressing support plate 23 downward, so that the connecting lower pressing support plate 23 can contact the ground, thereby supporting the whole, causing the universal wheels 15 to disengage from the ground, and enabling the whole to be used stably. When the height of the operating table body 17 needs to be adjusted, the connecting rocker 5 can be shaken to drive the connecting mounting disc 4 and the rotating rod 3 to rotate, and then drive the fixed mounting sleeve disc 6 and the first bevel gear 7 to rotate, thereby driving the second bevel gear 10, the movable threaded rod 9, the limiting top disc 12 and the fixed limiting collar 13 to rotate. As the movable threaded rod 9 rotates, the threaded connection block 18 can move up and down on the outer surface of the movable threaded rod 9, driving the operating table body 17 to move, so that the fixed guiding block 19 can move on the outer surface of the guiding rod, thereby stably adjusting the operating table body 17, making the whole more convenient and fast in the actual use process and easy to operate.

[0036] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
