[0026] according to Figure 2-3As shown, the shock absorbing mechanism 5 includes a rubber strip 501, an arc groove 502, a buffer rod 503, a No. 1 spring 504, a slider 505, a No. 2 spring 506 and a buffer plate 507. The inner sides of the No. 1 bracket 2 and the No. 2 bracket 3 are both provided with an arc groove 502, and the inner side of the arc groove 502 is slidably connected with a slider 505. One side of the slider 505 is provided with a No. 1 spring 504, and the other end of the slider 505 is provided with a No. 2 spring 506. Both the No. 1 spring 504 and the No. 2 spring 506 are located in the arc groove 502. One side of the slider 505 is connected with the buffer rod 503 through a movable shaft, and one end of the buffer rod 503 is connected with the buffer plate 507 through a movable shaft. The inner sides of the No. 1 bracket 2 and the No. 2 bracket 3 near the two ends of the buffer plate 507 are both pasted with rubber strips 501, and the cross-sectional shape of the buffer plate 507 is semicircular.

[0027] During specific implementation, the HVAC pipeline will generate a certain degree of vibration during the process of conveying the medium. When the pipe body 1 vibrates, the buffer plate 507 will be squeezed, and the buffer plate 507 will squeeze the buffer rod 503. Then the buffer rod 503 drives the slider 505 to slide in the arc groove 502 and squeeze the No. 1 spring 504 and the No. 2 spring 506.

[0028] according to Figure 1-2 and Figure 4-5 As shown, the docking mechanism 8 includes a reset spring 801, a pull rod 802, an annular groove 803, an annular block 804 and a limiting hole 805. The side of the No. 2 connector 9 close to the No. 1 connector 6 is fixed with an annular block 804, the side of the No. 1 connector 6 close to the annular block 804 is provided with an annular groove 803, the inner side of the No. 1 connector 6 close to the annular groove 803 is slidably connected with the pull rod 802, the outer side of the pull rod 802 is sleeved with a reset spring 801, the side of the annular block 804 close to the pull rod 802 is provided with a limiting hole 805, The limiting mechanism 7 includes a screw 701, a knob 702 and a limiting block 703.

The outer thread of the screw 701 is sleeved with the limiting block 703, and the limiting block 703 is located on one side of the pull rod 802. The end of the pull rod 802 close to the annular groove 803 is connected to a trapezoidal block. The pull rod 802 and the trapezoidal block are both provided with jacks on one side close to the limiting block 703. The cross-sectional shape of the limiting block 703 is "L" shaped.

[0029] In specific implementation, some HVAC pipes usually use flange bolts to connect the pipe to another pipe, which is time-consuming to connect. When the two pipe bodies 1 need to be connected together, the annular block 804 on one side of the No. 2 connecting head 9 can be inserted into the annular groove 803 of the No. 1 connecting head 6. At the same time, the annular block 804 squeezes the trapezoidal block of the pull rod 802, so that the pull rod 802 squeezes the reset spring 801 to one side and drives the trapezoidal block to rise. Then the annular block 804 completely enters the annular groove 803, and the reset spring 801 rebounds again to make the pull rod 802 drive the trapezoidal block to insert into the limiting hole 805, limit the annular block 804, and then rotate the knob 702 to drive the screw 701 to rotate, so that the limiting block 703 is inserted into the jack on one side of the pull rod 802, and the pull rod 802 is limited again. The elastic sealing ring 10 seals the interface of the pipe body 1, and the docking mechanism 8 facilitates the rapid connection of the pipe body 1 and another pipe body 1, thereby improving the installation convenience of the HVAC pipe.

[0030] Working principle: When using the HVAC pipe with a shock-absorbing structure, first, install the No. 1 bracket 2 on the top of the wall through the mounting frame 4, then place the pipe body 1 on the inner side of the No. 1 bracket 2, and then connect the No. 1 bracket 2 and the No. 2 bracket 3 together through bolts, and finally connect the pipe body 1 to another pipe body 1 through the docking mechanism 8 and the limiting mechanism 7. When the pipe body 1 transports the medium, the shock-absorbing mechanism 5 buffers the vibration generated by the pipe body 1, reduces the vibration generated by the HVAC pipe, improves the convenience of installation of the HVAC pipe and extends the service life of the HVAC pipe.
