DETAILED DESCRIPTION

[0017] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0018] A heat insulation and sound insulation device for a heating and ventilation pipeline, such as Figure 1-Figure 3As shown, it includes a sound insulation pad 1, a bolt 2, a nut 3, a reinforcing plate 4, a connecting piece 5, a first rotating plate 6, a fixing piece 7, a protrusion 8, a fixing plate 9 and a second rotating plate 10. Four bolts 2 are clamped at the front of the sound insulation pad 1, and nuts 3 are threadedly connected to the bolts 2. The nuts 3 are in contact with the sound insulation pad 1. Eight groups of first rotating plates 6 are arranged on the upper side of the sound insulation pad 1, and each group consists of four first rotating plates 6. The first rotating plates 6 are rotatably connected to the sound insulation pad 1 through the fixing piece 7, and the first rotating plates 6 in the same group are clamped with the sound insulation pad 1. There is a reinforcing plate 4, and five connecting parts 5 are provided on the upper and lower sides of the reinforcing plate 4. Two adjacent connecting parts 5 on different reinforcing plates 4 are detachably connected to each other. A protrusion 8 is connected to the upper right side of the sound insulation pad 1, and a groove is provided on the lower left side of the sound insulation pad 1. The lower sides of the left and right parts of the sound insulation pad 1 are connected to fixing plates 9, and soft pads are provided on the fixing plates 9 to avoid wear on the HVAC pipes. A second rotating plate 10 is rotatably connected on the side where the fixing plates 9 are close to each other, and injection holes 11 are provided on the fixing plates 9. Four connecting holes 12 are provided on the upper part of the sound insulation pad 1.

[0019] When using the utility model, first move the sound insulation pad 1 to the vicinity of the HVAC pipe that needs to be insulated and soundproofed, and then, according to the length of the HVAC pipe, engage the protrusion 8 with the groove on the other sound insulation pad 1 to splice the sound insulation pad 1 to the specified length. After the splicing of the sound insulation pad 1 is completed, rotate and open the second rotating plate 10, and then move the fixed plate 9 so that the HVAC pipe is located between the second rotating plate 10 and the fixed plate 9. Then, screw the nut 3 to disengage the bolt 2, and then rotate and adjust the second rotating plate 10 so that the fixed plate 9 and the second rotating plate 10 are in contact with the HVAC pipe. Then, wrap the sound insulation pad 1 around the fixed plate 9 and the second rotating plate 10, so that the sound insulation pad 1 wraps the HVAC pipe. After the sound insulation pad 1 is wrapped, the bolt 2 passes through the connecting hole 12 and re-engages with the nut 3 to cooperate with the insulation. The sound insulation pad 1 is fixed to soundproof the HVAC pipe, and the reinforcement plate 4 reinforces the sound insulation pad 1 to make the sound insulation pad 1 more stably fixed. After the sound insulation pad 1 is fixed, the thermal insulation foam is injected between the sound insulation pad 1 and the HVAC pipe from the injection hole 11 to insulate the HVAC pipe. When it is necessary to insulate and soundproof HVAC pipes of different diameters, the first rotating plate 6 on the fixing part 7 is rotated to separate the reinforcement plate 4 from the sound insulation pad 1, and then the sound insulation pad 1 of a specified length is replaced according to the diameter of the HVAC pipe, and then the reinforcement plates 4 of a specified number are spliced ​​through the connecting part 5, and then the first rotating plate 6 is rotated and reset, and the reinforcement plate 4 is fixed again, thereby achieving the effect of being able to splice and replace the sound insulation pad 1 to adapt to the insulation and sound insulation requirements of HVAC pipes of different lengths and diameters.
