DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] Please refer to Figures 1-7 As shown in the figure, the present application is a ventilation pipeline for laboratory safety management, which comprises a cavity 1, and a one-key dismounting mechanism is arranged inside the cavity 1. The one-key dismounting mechanism comprises a button rod 2 arranged inside the cavity 1, a first pressing block 3 fixedly connected to one side of the button rod 2 close to the cavity 1, an inclined block 4 arranged below the first pressing block 3, a transmission rod 5 fixedly connected to the side edge of the inclined block 4, a connecting plate 6 fixedly connected to the side of the transmission rod 5 away from the inclined block 4, a first spring 7 fixedly connected to the side edge of the connecting plate 6, an insertion rod 9 fixedly connected to the side of the connecting plate 6 away from the first spring 7, a filter screen 10 arranged on the side edge of the insertion rod 9, and a clamping groove 11 formed on the side of the filter screen 10 close to the insertion rod 9. When the button rod 2 is pressed and the first pressing block 3 is moved, the first pressing block 3 exerts pressure on the inclined block 4 and drives the inclined block 4 to slide inside the cavity 1, the inclined block 4 drives the connecting plate 6 to move and exerts pressure on the first spring 7 through the transmission rod 5, the connecting plate 6 drives the insertion rod 9 to disengage from the clamping groove 11, and the insertion rod 9 is disconnected from the filter screen 10 and is dismounted.

[0023] The button rod 2 and the cavity 1 are in sliding connection, the inclined block 4 and the cavity 1 are in sliding connection, and a circular groove 8 is formed on the side of the cavity 1 close to the first spring 7, and the first spring 7 is fixedly installed on the inner wall of the circular groove 8.

[0024] The side of the inclined block 4 close to the filter screen 10 is provided with a second pressing block 12.

[0025] When it is necessary to replace the filter screen in the ventilation pipeline of the laboratory in the embodiment, the one-key dismounting mechanism can be started by pressing the button rod 2. The button rod 2 slides in the cavity 1 and drives the first pressing block 3 fixedly connected to the other side of the button rod 2 to move. When the first pressing block 3 moves, the first pressing block 3 gradually presses the inclined block 4. Because the inclined surface of the inclined block 4 is connected to the cavity 1 in a sliding manner, the inclined surface is pressed, so that the inclined block 4 gradually slides in the cavity 1. When the inclined block 4 slides, the inclined block 4 drives the transmission rod 5 fixedly connected to the side of the inclined block 4 to move. When the transmission rod 5 moves, the transmission rod 5 drives the connecting plate 6 fixedly connected to the other side of the transmission rod 5 to move. The first spring 7 is fixedly connected to the side of the connecting plate 6 and the other end of the first spring 7 is fixedly installed on the inner wall of the circular groove 8 in the cavity 1. The elastic potential energy of the first spring 7 resists the connecting plate 6. The elastic potential energy of the first spring 7 enhances the fixing ability when the filter screen 10 normally operates. When the connecting plate 6 moves, the connecting plate 6 presses the first spring 7 and drives the plug rod 9 fixedly connected to the other side of the connecting plate 6 to move, so that the plug rod 9 gradually separates from the inside of the clamping groove 11 in the filter screen 10, so that the plug rod 9 gradually separates from the clamping groove 11 and the filter screen 10. The filter screen 10 is no longer fixed and is dismounted. When the inclined block 4 moves, the second pressing block 12 arranged on the side of the inclined block 4 also slides in the same way as the inclined block 4. The second pressing block 12 drives another set of transmission rod 5, connecting plate 6, first spring 7, circular groove 8 and plug rod 9 to operate in the same way, so as to realize synchronous bilateral fixing and dismounting of the filter screen 10. When a new filter screen 10 needs to be installed, the filter screen 10 is only needed to be pressed into the cavity 1 and the pressing of the button rod 2 is kept unchanged. When the filter screen 10 completely enters the cavity 1, the elastic potential energy of the first spring 7 can drive the plug rod 9 to enter the clamping groove 11 of the new filter screen 10 to be quickly fixed. The one-key dismounting and installation of the filter screen 10 can be quickly completed, the working time is reduced, and the safety risk is reduced.

[0026] In one embodiment, for the above-mentioned cavity 1, the side of the cavity 1 is provided with a connecting disc 13, and the side of the connecting disc 13 is fixedly connected with a ventilation corrugated pipe 14.

[0029] In the embodiment, the elastic partition plates 15 are symmetrically and fixedly connected to one side of the cavity 1 close to the filter screen 10. The two groups of elastic partition plates 15 keep close contact with the filter screen 10 by the elasticity of the elastic partition plates 15, so that the gas cannot directly enter the inside of the cavity 1 through the filter screen 10. The elastic clamping grooves 16 arranged at the bottom of the cavity 1 have the same function as the elastic partition plates 15, and the filter screen 10 is clamped in the elastic clamping grooves 16.

[0030] In one embodiment, the filter screen 10 is fixedly connected with the resisting plate 17 at the top.

[0031] In the embodiment, the resisting plate 17 arranged at the top of the filter screen 10 can facilitate the staff to take the filter screen 10.

The air flow monitoring assembly 19 is arranged in the inside of the ventilation corrugated pipe 14. The air flow monitoring assembly 19 can monitor the flow rate of the gas entering the inside of the ventilation corrugated pipe 14. By monitoring the change of the air speed of the fan assembly 18 under the same power, it can be judged whether the warning is needed.

[0035] In the embodiment, the valve pipe 20 and the fuse valve pipe element 21 arranged on the other side of the ventilation corrugated pipe 14 can perceive the change of the ambient temperature through the built-in fuse device such as a fuse link and a fusible plug. When the temperature exceeds a preset threshold value such as 74℃, 100℃ or is customized according to the requirement, the fuse material melts, triggers the valve closing mechanism, and rapidly cuts off the gas delivery in the pipeline to prevent accidents.

[0036] In one embodiment, the cavity 1 is fixedly connected with the mounting plate 22 on the side close to the elastic partition plate 15. The mounting hole 23 is arranged in the inside of the mounting plate 22. The cavity 1 is provided with the alarm lamp 24 on the side close to the elastic clamping groove 16.

[0037] In the embodiment, the cavity 1 is provided with mounting plates 22 on both sides, and two groups of mounting holes 23 are formed in each group of mounting plates 22. The device can be quickly fixed on the wall through the mounting plates 22 and the mounting holes 23. The alarm lamp 24 arranged on the side of the cavity 1 can send a warning to the staff.
