Description

Technical Field

[0001] This utility model relates to the technical field of heating and ventilation duct connectors, and in particular to a heating and ventilation duct connector. Background Technology

[0002] Heating and ventilation ducts are pipes used to transport air in HVAC systems. Galvanized steel sheet ducts are the most common type. They are made by galvanizing the surface of steel sheets, giving them good strength and corrosion resistance. They are widely used in HVAC systems in general commercial buildings and industrial plants because their strength can withstand certain pressures, and the galvanized layer prevents the steel sheet from rusting, extending its service life.

[0003] The aforementioned device lacks an adjustable connection structure for heating and ventilation ducts during use. This means that when installing existing heating and ventilation ducts, if the duct dimensions differ from the preset dimensions due to being too long or too short, it is impossible to connect them using existing duct sections. Based on the shortcomings of existing technology, this utility model designs a heating and ventilation duct connector. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a heating and ventilation duct connector with the feature of adjustable connection of the heating and ventilation duct.

[0005] This utility model is implemented as follows:

[0006] A heating and ventilation duct connector includes a first duct, a second duct, a mounting strip, and a connecting mechanism. A limit ring is fixedly connected to one side of the first duct, and a threaded rod is fixedly connected to the top of the first duct, with a nut threaded onto the outer surface of the threaded rod. The second duct is located on one side of the first duct, and has the same structure as the first duct and is symmetrically arranged. Two mounting strips are provided, and the two mounting strips are respectively installed on the first and second ducts. The connecting mechanism is located between the first and second ducts, and includes a sleeve, a through groove, a first sealing ring, a second sealing ring, an arc-shaped groove, and an arc-shaped groove. The sleeve has a through groove inside, and the two ends of the through groove are fixedly connected to the first and second sealing rings, respectively. The upper surface of the sleeve has an arc-shaped groove at both ends.

[0007] The two mounting strips are located on the upper part of duct 1 and duct 2 respectively. Taking duct 1 as an example, mounting strip 2 is provided at the bottom of duct 1. The two ends of mounting strip 1 and mounting strip 2 are connected by positioning rods. The two ends of mounting strip 1 are respectively hinged to connecting rods, and the other end of the connecting rods is hinged to connecting blocks.

[0008] The first arc-shaped groove is located on the side of the first sealing ring close to the first air duct, and the second arc-shaped groove is located on the side of the second sealing ring close to the second air duct.

[0009] The sleeve is fitted onto the outer surface of duct one and duct two. The threaded rods of duct one and duct two are respectively set in arc groove one and arc groove two. The limiting rings of duct one and duct two are both located between sealing ring one and sealing ring two.

[0010] The limiting ring, sealing ring one, and sealing ring two are all made of elastic material.

[0011] The gaps between the sleeve and duct one and duct two are filled with gap filler.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. In use, this utility model, by setting a sleeve, when it is necessary to fill the gaps in two air ducts and connect them, firstly, the sleeve is fitted onto the outer surface of air duct one and air duct two, and the sealing ring one and sealing ring two set inside the through groove are set on one side of the limiting ring, so as to seal the connection between air duct one and air duct two. After filling the gaps in the connection by moving air duct one, air duct two or the sleeve, the nut set on each threaded rod can be tightened to fix the sleeve on air duct one and air duct two. This device facilitates filling the gaps in air duct one and air duct two and connecting them. Attached Figure Description

A limiting ring 101 is fixedly connected to one side of the first duct 1, and a threaded rod 102 is fixedly connected to the top of the first duct 1. A nut 103 is threaded onto the outer surface of the threaded rod 102. The second duct 104 is disposed on one side of the first duct 1. The second duct 104 has the same structure as the first duct and is symmetrically arranged. The limiting ring 101, the sealing ring 103, and the sealing ring 204 are all made of elastic material.

[0022] Please see the appendix Figure 1 To be continued Figure 3 There are two mounting strips 2, which are respectively installed on duct 1 and duct 2 104. The two mounting strips 2 are located on the upper part of duct 1 and duct 2 104. Taking duct 1 as an example, mounting strip 2 201 is provided at the bottom of duct 1. The two ends of mounting strip 1 and mounting strip 2 201 are connected by positioning rod 202. The two ends of mounting strip 1 are respectively hinged to connecting rod 203. The other end of connecting rod 203 is hinged to connecting block 204. Mounting strip 1 and mounting strip 2 201 are used to support duct 1 and duct 2 104.

[0023] Please see the appendix Figure 1 To be continued Figure 5 The connecting mechanism 3 is located between duct 1 and duct 2 104. The connecting mechanism 3 includes a sleeve 301, a through groove 302, a first sealing ring 303, a second sealing ring 304, an arc-shaped groove 305, and an arc-shaped groove 306. The sleeve 301 has a through groove 302 inside, and the two ends of the through groove 302 are respectively fixedly connected to the first sealing ring 303 and the second sealing ring 304. The upper surface of the sleeve 301 has an arc-shaped groove 305 and an arc-shaped groove 306 at both ends. The first arc groove 305 is located on the side of the first sealing ring 303 near the first duct 1, and the second arc groove 306 is located on the side of the second sealing ring 304 near the second duct 104. The sleeve 301 is sleeved on the outer surface of the first duct 1 and the second duct 104. The threaded rods 102 of the first duct 1 and the second duct 104 are respectively arranged in the first arc groove 305 and the second arc groove 306. The limiting rings 101 of the first duct 1 and the second duct 104 are both located between the first sealing ring 303 and the second sealing ring 304.
