Detailed implementation manner
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Refer to Figures 1 to 5 , in the embodiment of the present invention, a shock-absorbing connection structure for a heat-insulating ventilation pipe includes a ventilation pipe 2. A connecting pipe 1 is arranged at the pipe connection of the ventilation pipe 2. Sealing slots 3 are fixedly connected to both ends of the connecting pipe 1. A connecting plug 4 is fixedly connected to one side of the ventilation pipe 2 close to the connecting pipe 1. The connecting plug 4 and the sealing slot 3 are slidably connected to each other. Fixed mounting bases 9 are fixedly connected to both sides of the connecting pipe 1. A sliding mounting cylinder 10 is slidably connected in the fixed mounting base 9. Positioning mounting bases 11 are fixedly connected to both ends of the sliding mounting cylinder 10. Shock damping dampers 12 fixedly connected to the positioning mounting bases 11 are arranged on both sides of the sliding mounting cylinder 10. The input ends of the shock damping dampers 12 are installed on both sides of the fixed mounting base 9. A screw rod 13 is slidably connected in the sliding mounting cylinder 10. A height-adjusting clamping nut 14 threadedly connected to the screw rod 13 is fixedly connected to the top of the sliding mounting cylinder 10. A fixed clamping nut 15 threadedly connected to the screw rod 13 is fixedly connected to the bottom of the sliding mounting cylinder 10;
[0023] A connecting component is installed between the connecting plug 4 and the sealing slot 3 for tightly connecting the connecting plug 4 and the sealing slot 3;
[0024] A fastening mounting component is installed at the top of the screw rod 13 for connecting the screw rod 13 to the wall;
[0025] In the present utility model, the connection plug 4 is first inserted into the sealed slot 3 to achieve the connection between the ventilation pipe 2 and the connecting pipe 1. Then, the connection plug 4 and the sealed slot 3 are tightly connected through the connection component, so as to achieve the tight connection between the ventilation pipe 2 and the connecting pipe 1. Then, the screw 13 is fixedly installed on the wall through the fixed installation component, thus completing the installation and fixation of the equipment. Moreover, the present utility model can also adjust the relative height between the sliding installation cylinder 10 and the screw 13 through the mutual cooperation of the height-adjusting clamping nut 14 and the fixed clamping nut 15, so as to adjust the relative installation height of the connecting pipe 1;
[0026] When the equipment is running, a high-speed air flow passes between the ventilation pipe 2 and the connecting pipe 1. At this time, since the connection plug 4 and the sealed slot 3 are mutually engaged, there are no protrusions or grooves at the connection between the ventilation pipe 2 and the connecting pipe 1, thus avoiding the generation of turbulence at the connection between the ventilation pipe 2 and the connecting pipe 1, and further reducing the mechanical vibration generated by the turbulence;
[0027] Then, as the gas in the ventilation pipe 2 flows, air flow friction occurs inside the ventilation pipe 2, and the ventilation pipe 2 will inevitably vibrate. The vibration first acts on the fixed mounting seat 9 through the ventilation pipe 2 and the connecting pipe 1, and the fixed mounting seat 9 acts on the shock-absorbing damper 12. At this time, the oscillation of the ventilation pipe 2 and the connecting pipe 1 can be shock-absorbed by the two shock-absorbing dampers 12 on both sides of the fixed mounting seat 9.
[0028] In one case of this embodiment, please refer to Figures 1 to 5 , a sealed shock-absorbing gasket 5 is arranged in the sealed slot 3. The present utility model realizes the elastic connection between the connection plug 4 and the sealed slot 3 through the arrangement of the sealed shock-absorbing gasket 5, and while achieving the sealing between the connection plug 4 and the sealed slot 3, it avoids the rigid contact between the connection plug 4 and the sealed slot 3, resulting in structural damage.
[0029] In one case of this embodiment, please refer to Figures 1 to 5 , the connection component includes a fitting groove 6 arranged in the connection plug 4. A threaded hole 7 is arranged at the bottom of the fitting groove 6. A connection block 8 arranged in the fitting groove 6 is fixedly connected to the sealed slot 3. An installation bolt 21 is arranged in the connection block 8, and the installation bolt 21 is in threaded connection with the threaded hole 7;
[0030] When the connection component inserts the connection plug 4 into the sealed slot 3, the connection block 8 is inserted into the fitting groove 6. At this time, the fitting groove 6 and the connection block 8 cooperate with each other. At this time, the connection block 8 and the threaded hole 7 coincide with each other. At this time, the installation bolt 21 can be passed through the connection block 8 and threadedly connected to the threaded hole 7, so as to realize the tight connection between the connection plug 4 and the sealed slot 3 through the mutual cooperation of the installation bolt 21 and the connection block 8.
[0031] In one case of this embodiment, please refer to Figures 1 to 5 , the fastening and mounting assembly includes a mounting frame 16. Fixed mounting grooves 17 are fixedly connected to both sides of the mounting frame 16. The fixed mounting grooves 17 are connected to the wall through expansion bolts. Adjusting mounting grooves 18 are fixedly connected to both ends of the mounting frame 16. A connecting bolt 19 is arranged in the adjusting mounting groove 18. The connecting bolt 19 is fixedly connected to the screw rod 13. The connecting bolt 19 passes through the adjusting mounting groove 18 and is threadedly connected to a fixing nut 20 arranged on the top of the mounting frame 16;
[0032] The fastening and mounting assembly first installs the expansion bolts into the wall, and fastens and mounts the mounting frame 16 to the wall through the mutual cooperation of the fixed mounting grooves 17 and the expansion bolts. Then, the connecting bolt 19 can pass through the adjusting mounting groove 18, and the fixing nut 20 can be tightened onto the connecting bolt 19. Moreover, the relative position between the connecting pipe 1 and the mounting frame 16 in the horizontal direction can be adjusted through the sliding connection between the adjusting mounting groove 18 and the connecting bolt 19.
