Description

Technical Field

[0001] This utility model relates to the technical field of HVAC construction, and in particular to a pipe connection structure for HVAC construction. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) systems play a crucial role in maintaining comfortable indoor temperature, humidity, and air quality. HVAC systems transport heat and air through various pipes and are an indispensable infrastructure in buildings.

[0003] In HVAC construction, pipe connections are of paramount importance. They must not only ensure the sealing of the piping system to prevent media leakage, but also guarantee the strength of the connections to withstand pressure and temperature changes during system operation and meet the requirements for long-term stable operation of the HVAC system.

[0004] However, traditional pipe connection methods such as welding, threading, or screwing, while providing a certain degree of stability, are relatively cumbersome, resulting in low pipe connection efficiency. Furthermore, gaps are easily created at the contact surfaces during pipe connection, posing a risk of leakage. Utility Model Content

[0028] Reference Figure 1-4 This utility model provides a connection structure for HVAC construction pipes, including:

[0029] The main unit 100 includes a first pipe body 101 and a second pipe body 102. The surfaces of the first pipe body 101 and the second pipe body 102 that are close to each other are movably fitted together, and the first pipe body 101 and the second pipe body 102 facilitate the foundation connection of the HVAC construction pipeline.

[0030] The connecting unit 200 includes a concave ring 201 and a convex ring 202. The concave ring 201 is fixedly connected to the outer surface of the first tube 101, and the convex ring 202 is fixedly connected to the outer surface of the second tube 102. The convex ring 202 is inserted into the concave ring 201. A fitting component 203 is provided on the convex ring 202, and a fixing component 204 is provided on the first tube 101. The connection between the concave ring 201 and the convex ring 202 facilitates the mutual connection between the first tube 101 and the second tube 102.

[0031] The bonding component 203 includes two grooves 203a, both of which are formed on the outer surface of the convex ring 202. Movable blocks 203b are slidably connected in both grooves 203a. Arc-shaped plates 203c are hinged to both movable blocks 203b. Both arc-shaped plates 203c are movably bonded to the outer surface of the concave ring 201. By hinged to the movable blocks 203b by the arc-shaped plates 203c, the concave ring 201 and the convex ring 202 are reinforced. Furthermore, the movable blocks 203b move within the grooves 203a, which is beneficial for stable operation.

[0032] Furthermore, the fixing component 204 includes two support plates 204a, which are symmetrically arranged. Both support plates 204a are fixedly connected to the outer surface of the first pipe body 101. Bolts 204b are threadedly connected to both support plates 204a. One end of each bolt 204b passes through the arc-shaped plate 203c and the concave ring 201, respectively. The other end of each bolt 204b is fixedly connected to a knob. The rod arm of each bolt 204b is fixedly connected to a clamping plate 204c. By turning the knob, the bolt 204b is threaded through the arc-shaped plate 203c and the concave ring 201, thereby fixing the connection between the first pipe body 101 and the second pipe body 102 and enhancing the connection firmness of the HVAC construction pipeline.

[0033] Furthermore, the two grooves 203a are symmetrically arranged, and the two arc-shaped plates 203c are movably fitted together and together form a ring. The movement of the arc-shaped plates 203c into a ring shape facilitates the enhancement of the protection of the concave ring 201.

[0034] Furthermore, the inner wall of the first tube 101 is fixedly connected with a plug ring 205, and the inner wall of the second tube 102 is fixedly connected with a perforated ring 206. The perforated ring 206 and the plug ring 205 are interlocked. The connection between the plug ring 205 and the perforated ring 206 facilitates the positioning and connection of the first tube 101 and the second tube 102.

[0035] Furthermore, adhesive sealing rings 207 are fixedly connected to the sides of the insertion ring 205 and the hole ring 206 that are close to each other. The two adhesive sealing rings 207 are bonded to each other and are located at the connection between the inner walls of the first pipe body 101 and the second pipe body 102. The adhesive sealing rings 207 enhance the connection between the first pipe body 101 and the second pipe body 102, and at the same time improve the sealing effect at the pipe connection.

[0036] During use, the concave ring 201 is connected to the convex ring 202, which facilitates the docking of the first pipe body 101 and the second pipe body 102. The arc plate 203c is hinged to the movable block 203b, which can strengthen the connection and protection between the concave ring 201 and the convex ring 202. At the same time, the movable block 203b moves in the groove 203a, making its operation more stable. When the knob is turned, the bolt 204b thread passes through the arc plate 203c and the concave ring 201, further fixing the pipe bodies on both sides and enhancing the firmness of the connection of the HVAC construction pipeline. The whole process is convenient and fast.

[0037] The insertion ring 205 is connected to the hole ring 206 to facilitate the positioning and connection of the first pipe body 101 and the second pipe body 102. At the same time, the sealing ring 207 is attached to strengthen the connection between the pipes and improve the sealing performance of the pipe connection.
