Description

Technical Field

[0001] The utility model relates to the technical field of glove boxes, in particular to a laboratory glove box capable of multi-angle operation. Background Technique

[0002] Laboratory glove boxes are widely used in the research and development and inspection of medical supplies, fine chemicals, nuclear industry, research and development of new energy materials and other laboratories. The glove box mainly consists of a box body and a gas system; generally, inert gas or nitrogen is filled in the box body of the glove box, or inert gas or nitrogen is circulated in the box body to remove active substances such as O2 and H2O in the glove box. When volatile substances are generated during the experiment in the laboratory or volatile reagents with certain environmental pollution are used, experimental operations also need to be carried out in the glove box at this time, which can not only protect the experimental personnel but also prevent environmental pollution. At the same time, in addition to qualitative and quantitative analysis of chemical substances, aseptic operations for microbial inoculation also need to be carried out in the operation box.

[0003] The existing patent CN217292416U discloses a multi-functional glove box convenient for taking, and two glove operation ports are arranged on the side wall of the front surface of the box body. The patent CN207357174U discloses a photocatalyst air filtration material experimental device, and the atmosphere chamber in the device includes a glove box, and a glove hole is connected to the front end of the glove box. Both CN217292416U and CN207357174U are glove boxes with a fixed-structure box body and gloves at fixed positions.

[0004] However, when the existing laboratory glove box is in use, the workbench inside it cannot rotate and adjust the operation angle, resulting in limited operation range and angle for the experimental personnel, and the operator cannot achieve multi-angle operation. Therefore, it is not very convenient to use. For this reason, we propose a laboratory glove box capable of multi-angle operation. Content of the Utility Model

Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution for a laboratory glove box that can be operated at multiple angles: A laboratory glove box that can be operated at multiple angles includes a box body 1. Support legs 10 are fixedly installed at the four corners of the bottom of the box body 1. Transparent plates 2 are fixedly installed around the box body 1. The upper end of the box body 1 is open, and a transparent cover plate 3 is placed at the upper port of the box body 1. Two spaced circular sleeves 4 are provided on each of the four sides inside the box body 1. The circular sleeves 4 are fixedly connected to the transparent plates 2 and communicate with the outside. Gloves are sleeved on the circular sleeves 4. An inner shaft 5 is rotatably installed at the center of the bottom inside the box body 1. A workbench 6 is arranged inside the box body 1. The workbench 6 is fixedly connected to the upper end of the inner shaft 5. The lower end of the inner shaft 5 penetrates through the box body 1, and a central wheel 7 is fixedly installed at the bottom of the inner shaft 5. Four transmission shafts 8 are rotatably installed at the bottom of the box body 1. Driven wheels 9 are fixedly installed at the ends of the transmission shafts 8. All four driven wheels 9 are engaged with the central wheel 7. Drive shafts 11 are rotatably installed on the outside of the bottom of the box body 1. Belt transmission mechanisms 12 are installed on the drive shafts 11 and the transmission shafts 8 on the same side. Grips are fixedly installed at the bottoms of the drive shafts 11. Anti-slip pads are provided at the bottoms of the support legs 10. Anti-slip patterns are provided on the top of the workbench 6. By placing experimental tools on the workbench 6, the operator inserts both hands into the box body 1 and puts them into the gloves on the circular sleeves 4. By performing experimental operations in the isolated space inside the box body 1, it can not only protect the experimental personnel but also prevent pollution to the environment.

[0023] Among them, as Figure 3 and Figure 4 shown, an inner cavity 13 is opened at the bottom of the box body 1. Lubricating fluid is contained inside the inner cavity 13. The inner cavity 13 is located inside the box body 1. A diversion mechanism is provided at the bottom of the box body 1. The diversion mechanism communicates with the inner cavity 13 and is used to divert the lubricating fluid in the inner cavity 13 to the central wheel 7. The diversion mechanism includes a plurality of nozzles 14. The nozzles 14 are all arranged towards the central wheel 7. The nozzles 14 are fixedly connected to the bottom of the box body 1 and the upper ends of the nozzles 14 communicate with the inner cavity 13. A cylinder 15 is arranged on one side of the box body 1. A diversion pipe 16 is fixedly installed at the bottom of the cylinder 15 and communicates with the box body 1. The diversion pipe 16 is fixedly connected to the box body 1 and communicates with the inner cavity 13. A valve is installed on the diversion pipe 16. By driving the transmission shaft 8 to rotate through the belt transmission mechanism 12, the driven wheel 9 on the transmission shaft 8 drives the central wheel 7 to rotate, thereby driving the workbench 6 to rotate around the inner shaft 5, and the angle of the experimental tools on the workbench 6 can be adjusted, so as to perform multi-angle adjustment.

[0024] The working principle of the present utility model is: By placing experimental tools on the workbench 6, the operator inserts both hands into the box body 1 and puts them into the gloves on the circular sleeves 4. By performing experimental operations in the isolated space inside the box body 1, it can not only protect the experimental personnel but also prevent pollution to the environment.

[0025] When the operating angle needs to be adjusted, the grip on the drive shaft 11 is rotated to drive the rotation of the drive shaft 11. The drive shaft 11 drives the rotation of the transmission shaft 8 through the belt transmission mechanism 12. The driven wheel 9 on the transmission shaft 8 drives the central wheel 7 to rotate, thereby driving the workbench 6 to rotate around the inner shaft 5. The angle of the experimental equipment on the workbench 6 can be adjusted, so as to perform multi-angle adjustment. Since the grip on the drive shaft 11 can be operated in different directions of the box body 1, different operators around the box body 1 can perform the angle adjustment work. By filling the lubricating liquid into the cylinder body 15, the lubricating liquid enters the inner cavity 13 through the diversion pipe 16, and the lubricating liquid in the inner cavity 13 is discharged from the nozzle 14 and drips on the central wheel 7, thereby lubricating the meshing part of the central wheel 7 and the driven wheel 9, making the operation of the device more stable and smooth.

[0026] The above is only the preferred implementation mode of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in this field without special description and limitation.
