Description

Technical Field

[0001] This utility model relates to the field of test benches, specifically a multifunctional test bench for laboratory use. Technical Background

[0002] Laboratory test benches are core equipment for experimental operations in fields such as chemistry, biology, and materials science, and their performance directly affects experimental efficiency, operational safety, and space utilization. With the development of modern experimental technology, experimental scenarios are becoming increasingly diversified, placing higher demands on the functional integration, adaptability, and safety protection of test benches. However, existing technologies still have significant limitations.

[0003] Most existing experimental benches are fixed, integrated designs with non-adjustable table height. Due to the large differences in the height of experimental personnel (usually ranging from 150cm to 190cm), the fixed table height can easily lead to fatigue during long-term operation. Furthermore, chemical and biological experiments often involve corrosive liquids, volatile gases, and high-temperature operations. Existing experimental benches generally lack integrated protective measures, and most laboratories need to build separate glass protective screens, which not only takes up extra space but also takes time to install and dismantle. Utility Model Content

[0004] (a) Technical issues

[0005] The technical problem this utility model aims to solve is that existing laboratory test benches have limited functions, non-adjustable table height, lack integrated protective measures, and require time-consuming and space-consuming installation of protective screens.

[0006] (II) Technical Solution

[0007] To solve the above technical problems, this solution provides a multifunctional laboratory test bench, achieved through the following technical means:

[0008] A multifunctional laboratory bench includes a back panel, with a shelf 1 and a shelf 2 at the upper end of the back panel, and a storage slot directly below the shelf 2. A cabinet is integrally formed on the same side of the back panel as the shelf 2 and the storage slot. Drawers and storage cabinets are provided at the top and bottom of the cabinet, respectively. A panel is provided on the top of the cabinet, with a water tank on the panel and a water outlet pipe at the diagonal of the water tank. A pair of parallel support plates 1 and 2 are provided on one side of the back panel and the cabinet, respectively. The bench also includes a lifting device and an adjustable protective device disposed between the support plates 1 and 2.

[0009] The lifting device includes a table and a driving device. The table is slidably disposed between two side support plates one and two support plates two. The driving device drives the table to move horizontally up and down between the support plates one and two support plates two.

[0010] An adjustable protective device with a limit sliding mechanism is located on one side of the tabletop.

[0011] As an improvement, the drive device includes a pair of bearings symmetrically arranged on support plate one and support plate two. The inner ring of the bearing is fitted with a threaded rod with positive and negative threads. The two ends of the threaded rod are threaded with connecting blocks. The front and back of each connecting block are rotatably connected to a connecting plate by a pin.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] A multi-functional laboratory bench, such as Figure 1 , Figure 3 As shown, it includes:

[0031] The back panel 1 has a shelf 2 and a shelf 3 on its upper end. Both shelves 2 and 3 are equipped with guardrails 14. Shelf 2 has a larger area than shelf 3 and can be used to classify and place items. The guardrails 14 prevent items from falling from above, increasing safety. Shelf 3 is also provided with a storage slot 4 directly below it, which can be used to place frequently used items. On the same side of the back panel 1 as shelves 3 and storage slot 4, a cabinet 5 is integrally formed. The cabinet 5 has drawers 7 and storage cabinets 6 on its upper and lower sides. Drawers 7 can be used to store light-proof reagents, and storage cabinets 6 can be used to store some larger instruments. The cabinet body 5 is equipped with a panel 8 on top, with a water sink 23 on the panel 8. A water outlet 24 is located diagonally on the water sink 23, allowing used utensils, towels, etc., to be washed in the water sink 23. Several hooks 15 are also parallel to each other on the upper outer side of the cabinet body 5, and a water collection trough 13 is slidably mounted on the cabinet body 5 below the hooks 15. Handles 25 are fixedly connected to the surface of the water collection trough 13, drawer 7, and storage cabinet 6. Used towels and brushes can be hung on the hooks 15, and the water collection trough 13 can be pulled out using the handles 25 to collect water, preventing water from dripping onto the ground. The back panel 1 and one side of the cabinet body 5 are respectively equipped with a pair of parallel support plates 9 and 10, and also include a lifting device and an adjustable protective device located between the support plates 9 and 10.

[0032] like Figure 2As shown, the lifting device includes a tabletop 12 and a driving device. The tabletop 12 is slidably disposed between two side support plates 9 and 10. The driving device drives the tabletop 12 to move horizontally up and down between the support plates 9 and 10. An adjustable protective device is slidably disposed on one side of the tabletop 12. The driving device includes a pair of bearings 17 symmetrically disposed on the support plates 9 and 10. The inner ring of each bearing 17 is fitted with a threaded rod 16. The bearings 17 allow the threaded rod 16 to rotate smoothly. The two ends of the threaded rod 16 are threadedly connected to connecting blocks 18. Each connecting block 18 has a connecting plate 20 rotatably connected to its front and back sides via a pin. The upper ends of the support plates 9 and 10 are symmetrically provided with sliding grooves 31. The side plates 11 at both ends of the tabletop 12 are fixedly connected to... The slider 30, which cooperates with the slide groove 31, is fixedly connected to the bottom surface of the table 12, and the end of each connecting plate 3 away from the connecting block 18 is rotatably connected to the positioning block 19. The connecting plate 18 serves to connect the connecting block 18 and the positioning block 19 and provides stable support for the table 12. One end of the threaded rod 16 passes through the support plate 9 and is located outside the support plate 9 and is fixedly connected to the rotating disk 21. The outer side of the rotating disk 21 is rotatably connected to the handle 22. The rotating disk 21 can be rotated by the handle 22 to rotate the threaded rod 16. The connecting blocks 18 threaded at both ends of the threaded rod 16 move closer and further away from each other, driving the connecting plate 18, which is rotatably connected to the positioning block 19 and the two connecting blocks 18 on the bottom surface of the table 12, to rotate, so that the slider 30 moves up and down in the slide groove 31 to achieve the lifting and lowering of the table 12.

[0033] like Figure 4 As shown, the protective device includes a baffle 26 inserted into the outer side of the table 12. The middle of the baffle 26 is a transparent glass plate 29, which facilitates the experimenter's observation of the experiment. The baffle 26 has rotating handles 27 at both ends. Several pairs of parallel support blocks 28 are also fixedly connected to the two side plates 11 of the table 12. The baffle 26 can be lifted by rotating the handles 27, and a suitable pair of support blocks 28 can be selected. Then, the rotating handles 27 can be rotated to a horizontal position to overlap with the support blocks 28. When not in use, the rotating handles 27 can be rotated to a vertical position to contact the surface of the table 12 for support. The upper end of the baffle 26 can be completely attached to the surface of the table 12, saving space.

[0034] In the specific implementation of this embodiment:

[0035] In use, hold the handle 22 to rotate the rotating disk 21. The rotating disk 21 drives the threaded rod 16 to rotate, and at the same time, the connecting blocks 18 connected to the two ends of the threaded rod 16 move closer and further apart. This drives the connecting plate 20, which is rotatably connected to the positioning block 19 on the bottom surface of the table 12 and the two connecting blocks 18, to rotate, causing the slider 30 to move up and down in the slide groove 31, thereby raising and lowering the table 12. After raising and lowering the table 12 to a height suitable for the experimenter's height, the experiment can be carried out. During the experiment, the baffle 26 can be lifted by rotating the handle 27, and a suitable pair of support blocks 28 can be selected. Then, rotate the handle 27 to a horizontal position to overlap with the support blocks 28 for protection. The experimental status can be observed through the transparent glass plate 29 in the middle of the baffle 26.

[0036] After use, the equipment, towels, etc. used in the experiment can be washed in the water tank 23. After washing, they can be hung on the hook 15. The water tank 13 can be pulled out by the handle 25 to collect water, so as to avoid water dripping onto the ground. The water in the water tank 13 can be completely pulled out and poured out. The rotating handle 27 can be rotated to a vertical position to contact the surface of the table 12 for support. The upper end of the baffle 26 can be completely attached to the surface of the table 12 to save space.
