Description

Technical Field

[0001] The utility model relates to the technical field of heating pipes, in particular to a heating and ventilation pipe which is easy to install. Background Art

[0002] The thickness and specifications of HVAC ducts can be changed according to requirements. Usually when connected, both ends of the duct are always connected to accessories (such as elbows, reducers). Generally, there are no grooves at both ends of the HVAC duct and they are equipped with sealing rings. The application range of HVAC ducts is very wide, including purification system return air ducts, central air conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mining gas extraction pipes, mining rubber-coated air ducts, etc.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] See also Figure 1-4 , a HVAC pipeline that is easy to install, including a main body component 1; the main body component 1 includes a pipeline 11, one end of which is provided with a pipeline 2 12; the pipeline 11 is provided with a disassembly component 2, and the disassembly component 2 includes: a fixed plate 21, fixedly connected to the outer wall of the pipeline 11; a limit block 22, slidably connected to the inside of the fixed plate 21, and two are symmetrically provided; a mounting block 23, each of the limit blocks 22 is fixedly connected to the bottom of the mounting block 23, and each of the mounting blocks 23 is slidably connected to the inside of the fixed plate 21; a spring 24, each of the limit blocks 22 is provided with a spring 24, and each Both ends of the spring 1 24 are respectively fixedly connected to the outer wall of the limit block 22 and the inside of the fixed plate 21; the extrusion block 25 is inserted into the inside of the fixed plate 21, and two are symmetrically arranged, and the two extrusion blocks 25 are slidably connected to the fixed plate 21; the connecting rod 26 is fixedly connected to the outer wall of the extrusion block 25; the handle 27 is fixedly connected to the top of the two extrusion blocks 25; the outer wall of the pipe 2 12 is fixedly connected to the positioning plate 4, the inner side of the fixed plate 21 is provided with a sliding groove, and the positioning plate 4 is slidably connected to the sliding groove of the fixed plate 21; the outer wall of the positioning plate 4 is fixedly connected to the spring 2 5.

[0029] When ready for use, install pipe 11 at the designated position, then the operator inserts pipe 21 into the inner side of fixing plate 21. During the insertion process, pipe 21 contacts with limit blocks 22 on both sides. Pipe 21 continues to move to squeeze limit blocks 22, squeeze limit blocks 22 completely into the inside of fixing plate 21, and at the same time, limit blocks 22 compress spring 1 24. When pipe 21 contacts pipe 11, limit blocks 22 are automatically rebounded into the limit groove of the outer wall of pipe 21 by spring 1 24, thereby limiting and fixing pipe 21. When pipe 21 needs to be disassembled, the operator pulls handle 27 upwards, and the movement of handle 27 drives the two connecting rods 26 upwards at the same time, so that the connecting rod 26 drives the squeezing block 25 upwards to squeeze the mounting block 23, so that the mounting block 23 is squeezed and drives the limit block 22 into the inside of fixing plate 21, canceling the fixation of pipe 21 by limit blocks 22, so that the The pipe 12 can be removed without the aid of external tools and the operation is relatively convenient, thereby improving the practicability of the device; the outer wall of the pipe 12 is fixedly connected to the positioning plate 4. When the operator installs the pipe 12, the positioning plate 4 is aligned with the slide groove and slides into the slide groove, so that the pipe 12 can enter the fixed plate 21 at the correct angle for installation, preventing the limit block 22 from being on the inner side of the fixed plate 21, making it inconvenient for the operator to check the correct position during installation, thereby improving the convenience of the device; the outer wall of the positioning plate 4 is fixedly connected to the spring 25, and the positioning plate 4 drives the spring 25 to enter the slide groove on the fixed plate 21. When the operator installs the spring 25 and contacts the inner wall of the slide groove, the positioning plate 4 continues to move to squeeze the spring 25. When the pipe 12 is disassembled, the spring 25 automatically pops out the pipe 12, preventing the operator from pulling the handle 27 with one hand and pulling the pipe 12 with the other hand, which is inconvenient, thereby improving the work efficiency of the operator.

[0030] Embodiment 2

[0031] See also Figure 1-4 , based on the first embodiment, a sealing function is added;

[0032] A sealing assembly 3 is provided on the pipeline 11, and the sealing assembly 3 includes: a rotating rod 31, which is inserted into the interior of the fixed plate 21 and is rotatably connected to the fixed plate 21; a bidirectional threaded rod 32, which is rotatably connected to the interior of the fixed plate 21; a bevel gear 33, the bottom end of the rotating rod 31 and the outer side wall of the bidirectional threaded rod 32 are fixedly connected with a bevel gear 33, and the two bevel gears 33 are meshed; connecting blocks 34, which are symmetrically arranged on the outer side walls of the bidirectional threaded rod 32 and are threadedly connected to the bidirectional threaded rod 32; a sealing plate 35, each of which is fixedly connected to a sealing plate 35 at the bottom of the connecting block 34, and each of the sealing plates 35 is slidably connected to the fixed plate 21; each of the outer side walls of the sealing plates 35 is fixedly connected with a sealing gasket 6; the outer side wall of the rotating rod 31 is provided with friction patterns.

[0033] During use, when the installation of pipe 2 12 is completed, the operator twists the rotating rod 31 by hand, and the two bevel gears 33 are meshed to drive the two-way threaded rod 32 to rotate. The rotation of the two-way threaded rod 32 drives the sealing plate 35 to move through the connecting block 34, and the contact between pipe 1 11 and pipe 2 12 is sealed to prevent gas from flowing out through the contact between pipe 1 11 and pipe 2 12, thereby improving the stability of the device; the outer wall of each sealing plate 35 is fixedly connected with a sealing gasket 6, and when the sealing plate 35 moves, the sealing gasket 6 is driven to move at the same time, and the sealing effect of the device is further enhanced by the sealing gasket 6 made of rubber, thereby improving the practicability of the device; the outer wall of the rotating rod 31 is provided with friction patterns, and when the operator rotates the rotating rod 31 by hand, the friction patterns can increase the friction between the operator's fingers and the rotating rod 31, preventing the operator's fingers from slipping when twisting, thereby improving the operator's work efficiency.
