DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In the embodiment, as shown in Fig. 1-4, a ventilation duct installation structure is provided. The utility model comprises a ventilation duct 1, a fixing plate 2 is provided at the rear side of the ventilation duct 1, two connecting components 3 are fixedly installed at the outer side of the ventilation duct 1, the connecting component 3 comprises a first rotating shaft 301 rotatably connected to the outer side of the ventilation duct 1, two connecting plates 302 are fixedly installed at the outer side of the first rotating shaft 301, connecting springs 303 are fixedly installed at the inner front walls of the two connecting plates 302, connecting rings 304 are fixedly connected at the rear sides of the two connecting springs 303, the interiors of the two connecting rings 304 are rotatably connected with a second rotating shaft 305, a cam 306 located between the two connecting plates 302 is fixedly installed at the outer side of the second rotating shaft 305, and a groove 307 corresponding to the cam 306 is provided at the outer side of the fixing plate 2;

Both ends of the second rotating shaft 305 are fixedly connected to the handle 4, and a stopper 5 is fixedly installed on the outer side of the handle 4;

Turn the handle 4 backwards, and the stopper 5 on the outside of the handle 4 will be located at the rear side of the fixed plate 2. If the ventilation pipe 1 on the front side is displaced, the stopper will have a blocking effect.

The size of the fixing plate 2 corresponds to the pipe opening of the ventilation pipe 1, and a groove 6 corresponding to the handle is provided on the outer side of the connecting plate 302;

When the handle 4 is rotated, the handle 4 can be rotated into the slot 6, at which time the cam 306 will rotate to a position perpendicular to the groove 307;

A shock-absorbing pad 7 corresponding to the fixing plate 2 is fixedly installed on the outer side of the ventilation pipe 1, and the shock-absorbing pad 7 is a shock-absorbing rubber;

When the two ventilation pipes 1 are butt-jointed, the shock-absorbing pad 7 on the outside of the ventilation pipe 1 will be located between the fixing plate 2 and the ventilation pipe 1. When the ventilation pipe 1 transmits gas, the connection between the fixing plate 2 and the ventilation pipe 1 will vibrate, and the shock-absorbing pad 7 can reduce the vibration there.

An anti-vibration pad 8 is installed at the bottom of the ventilation pipe 1, and a magnet 9 is fixedly installed on the outer side of the anti-vibration pad 8;

The anti-vibration pad 8 can be mounted on the bottom of the ventilation pipe 1 using a magnet 9, and the position of the anti-vibration pad 8 can be adjusted according to the position of the fixing bracket;

An air outlet 10 is provided at the bottom of the ventilation pipe 1, and a cover plate 11 corresponding to the air outlet 10 is rotatably connected to the inner bottom wall of the ventilation pipe 1;

The cover plate 11 is rotated, and the gas can be blown from the air outlet 10 to the room where the ventilation pipe 1 is located. When the gas is not needed, the cover plate 11 is rotated in the opposite direction until the cover plate 11 blocks the air outlet 10.

Working principle:

Step 1: Move the ventilation pipe 1 to be installed backward toward the already fixed ventilation pipe 1, and put the fixing plate 2 on the shock-absorbing pad 7 at the front end of the already fixed ventilation pipe 1;

Step 2: Rotate the connecting plate 302, the connecting plate 302 is stuck on the fixed plate 2, rotate the handle 4, the handle 4 drives the second rotating shaft 305 to rotate, and the cam 306 also rotates accordingly. When the cam 306 rotates, according to the change of the radius of the cam 306, the second rotating shaft 305 is lifted up, and the connecting spring 303 is compressed. When the handle 4 is rotated into the slot 6, the long end of the cam 306 is perpendicular to the groove 307 and presses against the groove 307. At this time, release the handle 4, the connecting spring 303 releases the spring force, presses the second rotating shaft 305 down, and presses the cam 306 connected to the second rotating shaft 305 on the groove 307, and presses the ventilation pipe 1 on the previous ventilation pipe 1;

Step 3: When the ventilation pipe 1 needs to be removed, the handle 4 is rotated in the opposite direction. At this time, the long end of the cam 306 is rotated to the outside of the groove 307. At this time, the connecting spring 303 will not clamp the cam in the groove 307. The connecting plate 302 is rotated in the opposite direction to remove the ventilation pipe 1.
