Detailed Description of the Embodiment

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4, the present utility model provides the following technical solutions: A ventilation pipeline for the safety management of a university laboratory, including two pairs of fixed rods 1, on which a ventilation pipeline body 2 capable of height adjustment is installed, and mounting holes 5 are opened on both pairs of fixed rods 1;

[0027] On both sides of the ventilation pipeline body 2, two pairs of mounting frames 3 for sleeving on the two pairs of fixed rods 1 are fixed. On both sides of the two pairs of mounting frames 3, a number of jacks 16 are equidistantly opened, and avoidance grooves 4 are also opened on both pairs of mounting frames 3;

[0028] On both pairs of fixed rods 1, inside the avoidance grooves 4, a pair of mounting blocks 6 are fixed. The fixed rods 1 are installed with two mounting plates 7 through the two pairs of mounting blocks 6. On the two mounting plates 7, an upper support plate 8 and a lower support plate 19 are respectively fixed. A screw rod 9 is rotatably connected between the upper support plate 8 and the lower support plate 19. An elevating block 10 is installed on the outer wall of the screw rod 9 through threads;

[0029] At the top of the lower support plate 19, below the elevating block 10, a fixed pipe 18 is fixed. On the outer wall of the fixed pipe 18, two symmetrically distributed mounting rods 14 are fixed. An L-shaped moving block 12 is slidably connected on the two mounting rods 14. On both L-shaped moving blocks 12, connecting plates 11 are connected through rotating shafts, and both connecting plates 11 are connected to both sides of the elevating block 10 through rotating shafts. A motor 17 for driving the screw rod 9 to rotate is installed on the lower support plate 19. On both L-shaped moving blocks 12, pins 15 for passing through the mounting holes 5 and the jacks 16 are fixed; During the use process, first, install the two sets of mounting frames 3 on the two pairs of fixed rods 1, and ensure that the jacks 16 are aligned with the mounting holes 5. Then, start the motor 17 to rotate the screw rod 9. The rotation of the screw rod 9 will drive the elevating block 10 to move downward, and then push the L-shaped moving blocks 12 to slide in opposite directions along the mounting rods 14. The pins 15 on the [L-shaped moving blocks 12] will pass through the mounting holes 5 and the two jacks 16, thereby fixing the position of the ventilation pipeline body 2.

[0030] When it is necessary to adjust the height of the ventilation pipeline body 2, just start the motor 17 again, rotate the screw rod 9 counterclockwise, the elevating block 10 will move upward, and the L-shaped moving blocks 12 will also move along the mounting rods 14 accordingly. The pins 15 will immediately disengage from the mounting holes 5 and the jacks 16, releasing the fixation of the ventilation pipeline body 2. At this time, the height of the ventilation pipeline body 2 can be easily adjusted. After the adjustment is completed, start the motor 17 again, the rotation of the screw rod 9 drives the elevating block 10 to move downward, and the L-shaped moving blocks 12 fix the position of the ventilation pipeline body 2 again.

[0031] Specifically, by Figure 4 It should be noted that there seems to be a missing part in the description of "The pins 15 on the [L-shaped moving blocks 12]" in the translation of . Please check and correct it if necessary.It can be seen that in this embodiment, rollers 13 are rotatably connected to both sides of the two L-shaped moving blocks 12, and the rollers 13 are in contact with the lower support plate 19; this can increase the stability of the L-shaped moving blocks 12 during movement, reduce friction, and improve the flexibility and durability of the overall structure.

[0032] Specifically, from Figure 2 It can be seen that in this embodiment, the thickness of the mounting block 6 is greater than the thickness of the mounting frame 3; this avoids the situation where one side of the mounting plate 7 fits against the mounting frame 3 when fixing the mounting plate 7, thus facilitating the sliding of the mounting frame 3 on the fixing rod 1.

[0033] Specifically, from Figure 3 It can be seen that in this embodiment, the mounting plate 7, the upper support plate 8, and the lower support plate 19 are all made of metal; this ensures the strength and stability of the entire ventilation pipeline system. At the same time, the metal material has good durability and corrosion resistance, extending the service life of the equipment.

[0034] Specifically, from Figure 4 It can be seen that in this embodiment, the rollers 13 are made of nylon; the nylon rollers 13 have good wear resistance and self-lubricating properties, which can effectively reduce friction with the metal surface, thereby reducing noise and extending the service life.

[0035] Specifically, from Figure 4 It can be seen that in this embodiment, the length of the pin 15 is greater than the width of the fixing rod 1; this facilitates the pin 15 to penetrate the fixing rod 1 and the mounting frame 3, ensuring the stability of the ventilation duct body 2 during installation.

[0036] It should be noted that the motor 17 and the ventilation duct body 2 are both commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to usage needs. Their working principles are common knowledge well-known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated too much herein.

[0037] The circuit connection involved in the present utility model is a common means adopted by those skilled in the art and can obtain technical inspiration through a limited number of experiments, belonging to the widely used prior art.

[0038] The components not described in detail herein are prior art.

[0039] The working principle and usage process of the present utility model: During use, first, install the two sets of mounting frames 3 on the two pairs of fixing rods 1 and ensure that the jacks 16 are aligned with the mounting holes 5. Then, start the motor 17 to rotate the screw rod 9. The rotation of the screw rod 9 will drive the lifting block 10 to move downward, and then push the L-shaped moving blocks 12 to slide in opposite directions along the mounting rods 14. The pins 15 on the upper will pass through the mounting holes 5 and the two jacks 16, thereby fixing the position of the ventilation duct body 2.

[0040] When it is necessary to adjust the height of the ventilation duct body 2, just start the motor 17 again. Rotate the screw rod 9 counterclockwise, and the lifting block 10 will move upward. The L-shaped moving block 12 will also move along the mounting rod 14 accordingly. The latch 15 will then disengage from the mounting hole 5 and the jack 16, releasing the fixation of the ventilation duct body 2. At this time, the height of the ventilation duct body 2 can be easily adjusted. After the adjustment is completed, start the motor 17 again. The rotation of the screw rod 9 drives the lifting block 10 to move downward, and the L-shaped moving block 12 fixes the position of the ventilation duct body 2 again.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
