Description

Technical Field

[0001] The utility model relates to the technical field of HVAC pipes, in particular to a HVAC pipe structure for HVAC engineering that is convenient to assemble and dock. Background Art

[0002] HVAC pipes are one of the necessary devices in HVAC projects. The thickness and specifications of HVAC pipes are configured according to requirements. Usually when the pipes are connected, both ends of the HVAC pipes are always connected to accessories (such as elbows, reducers, etc.). Usually, there are grooves and sealing rings at both ends of the HVAC pipes.

[0003] In the prior art, the patent application number CN202022675427.5 discloses a HVAC pipe structure based on HVAC engineering that is convenient for docking and assembly, comprising a first pipe column, a first connecting flange fixedly connected to one side of the first pipe column, a second connecting flange abutting against the side of the first connecting flange away from the first pipe column, a second pipe column fixedly connected to the side of the second connecting flange away from the first connecting flange, and an insert block and a limit block fixedly connected to the side of the second connecting flange close to the first connecting flange. The utility model provides a HVAC pipe structure for HVAC engineering that is convenient for assembly and docking. Through the cooperation between the first spring, the top block, the limit block, the second spring and the clamping block, the second connecting flange insert block and the limit block are pushed into the first and second sockets on the matching first connecting flange, so as to realize docking and locking of the two pipes. The operation method is simple, and the locking and docking and disassembly and separation operations of the pipe body are flexible and fast, which is convenient for disassembly and cleaning of the HVAC pipe and has a good use effect.

[0004] Since the liquid / gas medium transported in the HVAC pipe has a high pressure, the existing technology requires manual multi-layer reinforcement of the HVAC pipe joints during the process of transporting the medium through the HVAC pipe structure to prevent leakage at the HVAC pipe structure joints. This method of sealing the HVAC pipe joints is time-consuming and labor-intensive, and it is impossible to quickly splice and seal the HVAC pipes. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a HVAC pipe structure for HVAC engineering, which is easy to connect, seal, reinforce, and assemble.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A HVAC pipe structure for HVAC engineering that is convenient for assembly and docking, comprising a main body, a splicing assembly provided in the middle of the main body, a groove frame provided on one side of the splicing assembly, and a tight assembly connected to one end of the groove frame and the splicing assembly, and a sealing assembly provided on the outer surfaces of the splicing assembly and the tight assembly;

[0008] The sealing assembly includes a fixed plate, an electric telescopic rod, a sealing cover and protective teeth. The outer surfaces of the splicing assembly and the tight assembly are provided with a fixed plate, and the upper end of the fixed plate is connected to the electric telescopic rod. The inner wall end of the electric telescopic rod is provided with a sealing cover, and the outer surface of the sealing cover is provided with protective teeth.

[0009] Furthermore, the fixed plate and the electric telescopic rod are fixedly connected, and the electric telescopic rod forms a telescopic structure through a sealing cover and protective teeth. A sealing assembly is provided on the outer wall end of the tight assembly to facilitate the sealing and reinforcement of the connection between the sealing ring and the channel frame. By opening the electric telescopic rod at the top of the fixed plate, the sealing cover can be raised and lowered to fit over the connection between the sealing ring and the channel frame, sealing it and preventing leakage at the splicing point, which could hinder the heating pipe structure.

[0010] Furthermore, the sealing cover and the protective teeth are bonded together, and the protective teeth protect the sealing ring, thereby protecting the left heating pipe and the right heating pipe, and preventing the left heating pipe and the right heating pipe from being damaged by friction due to direct contact with the ground.

[0011] Furthermore, the tight assembly includes a sealing ring and an adhesive block. The sealing ring is connected to the right end of the groove frame, and the adhesive block is bonded to the rear end of the sealing ring. A groove frame is provided around the inner wall of the left heating pipe to facilitate the tight engagement of the tight assembly connected to the inner wall of the right heating pipe within the groove frame, thereby effectively preventing leakage of heated air from the left and right heating pipes.

[0012] Furthermore, the sealing ring and the bonding block are bonded together, and the sealing ring is bonded to the inner wall end of the right heating pipe through the bonding block, thereby enhancing the stability of the HVAC pipe structure assembly.

[0013] Furthermore, the splicing assembly includes a left heating pipe, a block seat, a dislocation slot seat, and a right heating pipe. The left heating pipe is disposed in the middle of the main body, and the block seat is connected to the inner wall of the left heating pipe. The dislocation slot seat is disposed on the right side of the block seat, and the right side of the dislocation slot seat is connected to the right side of the right heating pipe. The main body is quickly spliced ​​together by the splicing assembly, effectively splicing and installing the left and right heating pipes.

[0014] Furthermore, the left heating pipe forms a locking structure with the offset groove seat and the right heating pipe through the clamping block seat, and the clamping block seat and the offset groove seat are tightly fitted. The clamping block seat of the left heating pipe is clamped into the offset groove seat of the right heating pipe for locking installation, effectively preventing the left and right heating pipes from slipping and falling off due to poor tightness.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] A sealing component is provided on the outer wall end of the tight component, which is convenient for sealing and reinforcing the connection between the sealing ring and the groove frame. By opening the electric telescopic rod on the top of the fixed plate, the sealing cover can be lifted and fitted on the connection between the sealing ring and the groove frame to seal it, avoiding manual sealing of the HVAC pipe and realizing automatic sealing, which effectively prevents leakage at the joints and causes difficulty in heating transportation of the HVAC pipe structure. The sealing ring is protected by the protective teeth, which can protect the left heating pipe and the right heating pipe to prevent the left heating pipe and the right heating pipe from being damaged by friction due to direct contact with the ground.
