Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a composite heat-insulating ventilation duct. Background Art

[0002] Ventilation ducts are pipe systems used in buildings for ventilation, air exchange, smoke exhaust, etc. They can be directly connected to the outlet of fan equipment such as central air conditioning ventilation systems. They can introduce fresh air into the room and exhaust the indoor polluted air to keep the indoor air fresh and comfortable.

[0003] It has been found in actual use that the existing ventilation ducts have the following deficiencies:

[0004] Flange connection is one of the most commonly used joints in ventilation ducts. It has the characteristics of simple structure, easy installation, strong disassembly, and good tightness. However, the joints of the duct sections are exposed at the outer ends, and the connection fixing structure is at the outer ends, resulting in the ventilation duct's sealing and thermal insulation performance cannot be guaranteed.

[0005] Furthermore, since the ventilation duct is made of metal, it is easily affected by the internal and external environment during ventilation. The ventilation duct expands and contracts due to heat and cold, causing the joints of the ventilation duct to deform, thereby increasing the gap at the joint of the ventilation duct and affecting the overall sealing of the ventilation duct.

[0006] Therefore, the present application provides a composite thermal insulation ventilation duct to meet the needs. Utility Model Content

[0007] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a composite thermal insulation ventilation duct.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] A composite thermal insulation ventilation duct comprises: an angle steel flange air duct, a connecting joint, a movable plate, an air duct section, a connecting plate, a limit frame, a mounting seat and a supporting plate, wherein the front end of the angle steel flange air duct is provided with an air inlet, the end of the angle steel flange air duct away from the air inlet is provided with a connecting joint, the side of the connecting joint is provided with a movable plate, the other end of the connecting joint is provided with an air duct section, the inner surface of the air duct section is provided with a slot, the interior of the air duct section is provided with a connecting plate, the interior of the connecting joint is provided with a limit frame, the inner side of the limit frame is provided with a mounting seat, and the bottom of the mounting seat is provided with a supporting plate.

[0010] Preferably, the connecting joint and the air duct section are both rectangular in shape, the connecting joint and the air duct section fit together, and one end of the air duct section is inserted into the interior of the connecting joint.

[0011] Preferably, the limiting frame is located in the middle of the connecting section, and the limiting frame surrounds the inner wall of the connecting section.

[0012] Preferably, the limiting frame is rectangular, and one end of the air duct section rests against the end surface of the limiting frame.

[0013] Preferably, the slots provided on the inner surface of the air duct segment are vertically distributed along the openings at both ends of the air duct segment, and the connecting plates are vertically inserted into the interior of the air duct segment along the slots.

[0014] Preferably, the connecting plate is in a "convex" shape, and one end of the connecting plate protrudes outward from the slot and the inner wall of the air duct section.

[0015] Preferably, one end of the connecting plate fits with the mounting seat, and when one end of the air duct section is inserted into the interior of the connecting joint, the connecting plate is inserted inwardly into the mounting seat.

[0016] Preferably, two groups of mounting seats are provided, and the two groups of mounting seats are mirror-symmetrically located at the left and right ends of the limiting frame respectively.

[0017] Preferably, a rectangular opening is provided on one side of the connecting joint, and the movable plate is axially embedded in the opening of the connecting joint.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] 1. One end of the duct section is inserted into the interior of the connecting joint, so that when the ventilation duct is installed, the connection of the duct section is wrapped by the connecting joint, which can hide the connection seam of the duct section. One end of the connecting plate can be inserted into the mounting seat from the inner side of the duct section through the limiting frame, docked with the mounting seat, and locked with the limiting frame. The connecting plate is inserted inwardly into the mounting seat, so that the connection and fixing structure of the ventilation duct is inside, effectively ensuring the sealing of the ventilation duct and effectively improving the thermal insulation of the ventilation duct.

[0020] 2. When the duct sections are connected to each other or to the angle steel flange ducts, they are in contact with the limit frame. The limit frame can limit the position of the duct section. The limit frame can seal and separate the ports of the duct sections at both ends, thereby avoiding the situation where gaps are generated at the connection when the duct sections are deformed due to thermal expansion and contraction due to temperature, and effectively ensuring the overall sealing of the ventilation duct.
