The U-shaped installation piece 27 that is connected with the ceiling and is the level and place is connected to the shock attenuation pole 23 upper end, and installation piece 27 upper end uses expansion bolts to be connected with the ceiling, and shock attenuation pole 23 upper end passes installation piece lower extreme and threaded connection has mounting nut 25, and mounting nut 25 lower extreme and the inside wall lower extreme butt of installation piece. The lower end of the shock-absorbing rod 23 passes through the upper end surface of the connecting frame 22 and is inserted into the inner cavity of the connecting frame 22, and the lower end thereof is connected with a shock-absorbing nut 26 through threads. The damping springs 24 are respectively sleeved on the parts of the damping rods 23 arranged in the connecting frame 22, the upper ends of the damping springs are abutted with the upper ends of the inner cavities of the connecting frame 22, and the lower ends of the damping springs are abutted with the upper ends of the damping nuts 26. Utilize damping spring 24 to slow down the vibrations of wind cabinet 1, make wind cabinet 1 can carry out slight removal along with the vibrations of tuber pipe, make the difficult production of junction of wind cabinet 1 and tuber pipe damage to reduce the emergence of the condition of leaking out.

As shown in fig. 1, the installation space between the air duct and the ceiling is different due to the different sizes of the different air ducts. Therefore, the lower end of the connecting frame 22 is connected with an adjusting mechanism 3 for adjusting the distance between the connecting plate 21 and the ceiling, and the adjusting mechanism 3 comprises a connecting rod 31 connected with the connecting frame 22 and two adjusting nuts 32 in threaded connection with the connecting rod 31. The connecting rod 31 is welded to the lower end surface of the lower end of the connecting frame 22, the lower end of the connecting rod passes through the connecting plate 21 to slide up and down, and the two adjusting nuts 32 connected with the same connecting rod 31 clamp the connecting plate 21 together. The adjusting nut 32 is used for adjusting the distance between the connecting plate 21 and the ceiling, so that the mounted wind cabinet 1 can be adapted to wind pipes with different sizes.

As shown in fig. 2, since the wind pipes of the wind cabinet 1 can generate vibration along the horizontal plane during use, the connecting rods 31 are connected to damping mechanisms 4 for adjusting the horizontal vibration of the connecting plates 21, and each damping mechanism 4 includes a damping ring 41 fixed to the upper end of the connecting plate 21 by bolts, a plurality of sliding rods 42 connected to the damping ring 41 in a sliding manner, and a sliding spring 43 for driving the sliding rods 42 to move toward the axis of the damping ring 41. A plurality of sliding grooves 411 are formed in the circumferential direction of the inner wall of the shock absorption ring 41, and the axis of each sliding groove 411 penetrates through the axis of the shock absorption ring 41. The pole that slides 42 is arranged in respectively and is slided in the groove 411 that slides, and its one end welding that is close to the shock attenuation ring 41 axis has butt piece 421, and butt piece 421 is connected with connecting rod 31 lateral wall, and damping spring 24 cup joints respectively in the pole 42 that slides, and damping spring 24's one end and the butt of shock attenuation ring 41 inner wall butt, the other end of shock attenuation ring 41 and the butt piece 421 are close to the terminal surface butt of the pole 42 that slides. The connecting rod 31 is applied with elastic force by the sliding spring 43 around the axis of the connecting rod 31, so that the connecting plate 21 can slightly move in the horizontal plane, the air cabinet 1 can move along with the movement of the air duct, and the joint of the air cabinet 1 and the air duct is not easy to damage.

As shown in fig. 2, since the abutting block 421 may apply pressure to the thread formed on the connecting rod 31, the thread of the connecting rod 31 may be damaged, thereby affecting the use of the adjusting mechanism 3. Therefore, the connecting rods 31 are all sleeved with the abutting rings 44, and one end of the abutting block 421 close to the axis of the shock absorbing ring 41 is abutted with the abutting rings 44. The abutment ring 44 is not in direct contact with the thread of the connecting rod 31 by means of the abutment ring 44, so that the thread of the connecting rod 31 is not easily damaged.

As shown in fig. 2, since the contact between the abutting block 421 and the outer wall of the abutting ring 44 is a line contact, the contact area between the abutting block 421 and the outer wall of the abutting ring 44 is small, and thus the contact portion between the abutting block 421 and the abutting ring 44 is easily deformed. Therefore, the end surface of the abutting block 421 close to the shock absorbing ring 41 is adhered with the flexible pad 45, and the end surface of the flexible pad 45 far from the abutting block 421 abuts against the outer wall of the shock absorbing ring 41. At this time, the flexible pad 45 is deformed when contacting the damper ring 41, so that the contact area between the contact block 421 and the damper ring 41 is increased, and the contact portion between the damper ring 41 and the contact block 421 is not easily deformed.

As shown in fig. 2, in order to prevent the abutting ring 44 from being separated from the damping ring 41 during use, the upper and lower end faces of the abutting ring 44 are coaxially connected with the limiting ring 46 by bolts, and the end faces of the limiting ring 46 close to the abutting ring 44 are respectively connected with the two end faces of the damping ring 41. The position of the abutting ring 44 is limited by the limiting ring 46, so that the abutting ring 44 is not easy to be separated from the damping ring 41, and the using process of the damping mechanism 4 is more stable.

As shown in fig. 2, in order to reduce the friction between the retainer ring 46 and the damper ring 41, the horizontal movement of the abutment ring 44 in the inner cavity of the damper ring 41 is facilitated. A plurality of rolling grooves 461 are formed in the end face, close to the shock absorption ring 41, of the limiting ring 46, balls 48 are connected in the rolling grooves 461 in a rotating mode, and the balls 48 are abutted to the end face of the shock absorption ring 41. The sliding friction between the retainer ring 46 and the damper ring 41 is converted into rolling friction by the balls 48, so that the frictional force between the retainer ring 46 and the damper ring 41 is reduced, and the movement of the abutment ring 44 in the horizontal direction is not easily affected.

As shown in fig. 2, since the abutment ring 44 and the connecting rod 31 are in rigid contact when they are in contact, the threads on the surface of the connecting rod 31 are still easily damaged. Therefore, the inner wall of the abutting ring 44 is coaxially adhered with the buffer sleeve 47, and the inner wall of the buffer sleeve 47 abuts against the side wall of the connecting rod 31. The impact between the buffer sleeve 47 and the connecting rod 31 is relieved by using the buffer sleeve 47, meanwhile, the contact area between the connecting rod 31 and the buffer sleeve 47 is increased when the buffer sleeve 47 deforms, the pressure on the thread of the connecting rod 31 is reduced, and the thread of the connecting rod 31 is not easy to damage.

The working principle is as follows:

when the wind pipe generates vertical vibration, the damping spring 24 applies vertical elastic force to the connection frame 22, so that the connection plate 21 can slightly move in a vertical space.

When the air duct vibrates in the horizontal direction, the connecting plate 21 moves in the horizontal plane by the sliding of the sliding rod 42, and the sliding spring 43 applies an elastic force to the sliding rod 42 to limit the moving speed of the sliding rod 42, so that the vibration amplitude of the connecting plate 21 in the horizontal plane is reduced.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
