Description

Technical Field

[0001] This utility model relates to the field of laboratory bench technology, and in particular to a ventilation laboratory bench. Background Technology

[0002] Laboratory benches are widely used in laboratories, allowing operators to easily place experimental equipment for testing.

[0003] A search revealed a novel ventilation experimental bench disclosed in publication number "CN210906262U". The bench includes an experimental platform, two load-bearing plates, a top plate, an exhaust fan, an intake pipe, an intake hood, and an exhaust pipe. The two load-bearing plates are fixedly installed on top of the experimental platform, and the top plate is fixedly installed on top of the two load-bearing plates. The exhaust fan is fixedly installed on top of the top plate. This experimental bench is easy to operate, and the adsorption components and filters can purify the gas to a certain extent.

[0004] The aforementioned experimental platform achieves air purification by venting from the top. However, during use, we found that installing this device on the top of the platform affects operability during the experiment. Furthermore, the direction of the venting cannot be adjusted during use, which can easily lead to the inability to quickly expel odorous gases. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1-3 The ventilation test bench shown includes a test bench 1. A hollow partition 5 is fixedly installed in the middle of the top of the test bench 1. Air inlets 7 are opened on both sides of the hollow partition 5. Multiple air regulating plates 8 with synchronously adjustable angles are rotatably connected inside the two air inlets 7. A duct 13 is fixedly connected to the bottom of the hollow partition 5. An equipment box 3 is fixedly installed on one side of the bottom of the test bench 1. An exhaust assembly is installed inside the equipment box 3. A support plate 2 is fixedly installed on the other side of the bottom of the equipment box 3.

[0019] Specifically, a hollow partition 5 is installed at the top of the experimental platform 1. The hollow partition 5 is connected to the exhaust fan 11 through the air duct 13. Multiple air adjustment plates 8 are installed at the air inlet 7 of the hollow partition 5. When ventilation is carried out, the size of the exhaust fan and the air inlet can be adjusted as needed, thereby improving the ventilation effect of the experimental platform 1.

[0020] according to Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a ventilation test bench. Multiple power sockets 9 are fixedly installed at equal intervals on both sides of the bottom of a hollow partition 5. A liftable vertical plate 18 is provided at the center of the hollow partition 5. Multiple horizontally arranged through slots 19 are equally spaced on both sides of the vertical plate 18. I-shaped sliders are slidably connected inside each of the through slots 19. One end of each I-shaped slider is rotatably connected to a second connecting rod 17. One end of the second connecting rod 17 is rotatably connected to the center of one side of a corresponding air regulating plate 8. A top block 16 is fixedly installed at the top of the vertical plate 18. The top of the top block 16 is rotatably connected to two first connecting rods 15. The top of the hollow partition 5 is provided with a T-shaped groove 14. Two T-shaped sliders 21 are slidably connected inside the T-shaped groove 14. The bottom of the two T-shaped sliders 21 are rotatably connected to the end of the corresponding first connecting rod 15. Two bidirectional trapezoidal screws 20 are rotatably connected to both sides of the inner wall of the T-shaped groove 14. The two ends of the bidirectional trapezoidal screws 20 are threaded to the center of the corresponding T-shaped sliders 21. A knob 6 is fixedly installed at one end of the bidirectional trapezoidal screws 20 through the T-shaped groove 14.

[0021] Specifically, the knob 6 drives the bidirectional trapezoidal screw 20 to rotate, which in turn drives the two T-shaped sliders 21 to move towards the center or to the sides. The movement of the T-shaped sliders 21 causes the first connecting rod 15 to rotate by squeezing or pulling. The rotation of the first connecting rod 15 pushes the vertical plate 18 to rise or fall. The rise or fall of the vertical plate 18 causes the second connecting rod 17 to rotate, and the rotation of the second connecting rod 17 causes the air regulating plate 8 to rotate and adjust its direction.

[0022] A filter screen 12 for filtering dust is fixedly installed at the bottom inside the hollow partition 5.

[0023] Specifically, the installed filter 12 can filter the air entering the hollow partition 5, reducing the amount of dust entering the exhaust fan 11.

[0024] according to Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a ventilation test bench. The exhaust assembly includes an exhaust fan 11. A cavity 10 is opened inside the equipment box 3. The exhaust fan 11 is fixedly installed inside the cavity 10. The air inlet of the exhaust fan 11 is fixedly connected to the air duct 13. An exhaust port 4 is opened on one side of the cavity 10. A dustproof net is fixedly installed inside the exhaust port 4.

[0025] Specifically, through the exhaust port 4, the air drawn out by the exhaust fan 11 can be quickly discharged from the exhaust port 4. It should be noted that the exhaust port 4 can be connected to an exhaust duct to discharge the air outside the laboratory.

[0026] The working principle of this utility model is as follows: When conducting experiments using this ventilation test bench, first connect the power supply. When ventilation is required, turn on the exhaust fan 11. The exhaust fan 11 draws air to ventilate the top of the test bench 1. When the ventilation direction needs to be adjusted, manually turn the knob 6. The knob 6 drives the rotation of the bidirectional trapezoidal screw 20. The bidirectional trapezoidal screw 20 drives the two T-shaped sliders 21 to move towards the center or adjacent sides. The movement of the T-shaped sliders 21 drives the first connecting rod 15 to rotate. The rotation of the first connecting rod 15 pushes the vertical plate 18 to rise and fall. During the rising and falling of the vertical plate 18, the second connecting rod 17 rotates. The rotation of the second connecting rod 17 drives the air regulating plate 8 to rotate, thereby adjusting the angle of the air regulating plate 8 and achieving air intake from different directions.
