Description

Technical Field

[0001] The utility model relates to the technical field of air delivery, in particular to an air duct which can be quickly spliced. Background Art

[0002] Ventilation ducts are pipe systems used for ventilation and air circulation in buildings. They can introduce fresh air into the building and exhaust dirty air, thereby keeping the indoor air fresh and ensuring that the indoor air quality meets the standard. Ventilation ducts are generally made of metal, plastic or composite materials, and are resistant to corrosion, high temperature and pressure. Ventilation duct systems usually include components such as air inlets, fans, filters, air outlets, air valves, and pipes connecting these components. The design of ventilation ducts needs to consider factors such as air flow rate, pipe cross-sectional area, and layout method to ensure that indoor air can circulate and circulate effectively.

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.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an air duct that can be quickly spliced, including a shell 1, the left and right sides of the shell 1 are fixedly connected with a fixing ring 3, the rear side of the front fixing ring 3 is fixedly connected with a fixing shell 4, the top of the right side of the inner wall of the fixing shell 4 is fixedly connected with a fixing plate 5, the front and rear sides of the bottom wall of the fixing plate 5 are fixedly connected with springs 6, the bottom ends of the two springs 6 are fixedly connected with displacement plates 7, the front and rear sides of the bottom wall of the displacement plate 7 are provided with engaging grooves 8, the rear side of the rear fixing ring 3 is fixedly connected with a connecting shell 10, the front and rear ends of the right side of the inner wall of the connecting shell 10 are fixedly connected with engaging plates 11, and the two engaging plates 1 The right side of 1 is respectively engaged with the corresponding engaging groove 8, the middle part of the bottom wall of the displacement plate 7 is fixedly connected with a movable column 9, the front side of the front fixing ring 3 is provided with a locking assembly, the rear side of the shell 1 is provided with an opening and closing mechanism 2, the locking assembly includes a rotating groove 13, the interior of the rotating groove 13 is opened on the front side of the front shell 1, the front side of the front fixing ring 3 is rotatably connected with a locking piece 14, the front side of the rear fixing ring 3 is provided with a locking groove 15, and the left end of the locking piece 14 is engaged with the locking groove 15; the upper and lower sides of the inner wall of the shell 1 are provided with arc grooves 20; the internal dimensions of the two fixing rings 3 match the external dimensions of the shell 1;

[0030] Specifically, pressing the movable column 9 causes the displacement plate 7 to move accordingly. During the movement of the displacement plate 7, the two engaging plates 11 are separated from the corresponding engaging grooves 8, and the locking piece 14 is rotated so that the left end of the locking piece 14 is smoothly disengaged from the locking groove 15 under the guidance of the rotating groove 13. At this time, the locking function of the locking piece 14 is released, and the two fixing rings 3 are separated by pulling the rear fixing ring 3. The entire disassembly process does not require the use of any additional tools, which is simple and efficient. When the air duct needs to be installed, just follow the reverse order of the disassembly steps. Due to the close fit between the components and the easy operation during the whole process, the two arc grooves 20 facilitate air flow, and the internal dimensions of the two fixing rings 3 match the external dimensions of the outer shell 1, so that the fixing ring 3 is easy to fix, thereby facilitating the connection of the air duct.

[0031] Reference Figure 3The opening and closing mechanism 2 includes a flip cover 201, the front side of the flip cover 201 is arranged on the rear side of the shell 1, the bottom wall of the flip cover 201 is fixedly connected with a connecting plate 202, the rear side of the connecting plate 202 is threaded with a threaded knob 203, a slot 205 is provided at the bottom of the rear side of the shell 1, the front side of the connecting plate 202 is engaged with the slot 205, the front end of the threaded knob 203 is threadedly connected to the bottom of the rear side of the shell 1, a square groove 206 is provided at the rear side of the flip cover 201, a sealing ring 204 is fixedly connected to the front side of the flip cover 201, the front side of the sealing ring 204 is engaged with the square groove 206, and the left side of the shell 1 is rotatably connected to the top wall of the flip cover 201 through a hinge 207;

[0032] Specifically, the connection between the connecting plate 202 and the housing 1 is released by rotating the threaded knob 203. When we rotate and disengage the threaded knob 203, the flexibility of the flip cover 201 is revealed. By flipping the flip cover 201, the connection between the connecting plate 202 and the slot 205 is easily released. As the flip cover 201 is flipped, the connection between the sealing ring 204 and the square slot 206 is also disconnected. This design cleverly solves the cumbersome problem of disassembling multiple parts in traditional air duct maintenance, greatly improving maintenance efficiency. At the same time, the presence of the sealing ring 204 ensures the sealing of the air duct during normal operation, effectively preventing air leakage and dust from entering. The inside of the air duct can be easily maintained and repaired.

[0033] Reference Figure 1 and 2 The upper and lower ends of the left side of the front fixing ring 3 are both provided with sealing grooves 17, and the upper and lower ends of the right side of the rear fixing ring 3 are both fixedly connected with sealing plates 16, and the rear ends of the two sealing plates 16 are respectively engaged with the corresponding sealing grooves 17; the front and rear ends of the left side of the front fixing ring 3 are both fixedly connected with clamping columns 18, and the front and rear ends of the right side of the rear fixing ring 3 are both provided with holes 19, and the left ends of the two clamping columns 18 are respectively engaged with the holes 19; a protective shell 12 is provided at the bottom of the movable column 9, and the top of the protective shell 12 is rotatably connected to the bottom wall of the fixed shell 4 through a hinge;

[0034] Specifically, the rear ends of the two sealed plates 16 are respectively engaged with the corresponding sealing grooves 17, so that the sealing of the two fixing rings 3 can be improved. The left ends of the two clamping columns 18 are respectively engaged with the holes 19, so that the connection effect of the air duct can be improved. The protective shell 12 can protect the movable column 9 and prevent accidental touch.

[0035] Working principle: When starting to disassemble, by pressing the movable column 9, the displacement plate 7 is displaced together, thereby separating the two engaging plates 11 from the corresponding engaging grooves 8, and then rotating the locking piece 14, so that under the action of the rotating groove 13, the left end of the locking piece 14 is separated from the locking groove 15, and the two fixing rings 3 are separated by pulling the rear side fixing ring 3, so that the air duct can be disassembled and installed with one click, thereby avoiding the need for additional tools to assist in installation, improving installation efficiency, and facilitating operation for operators, and by twisting the threaded knob 203, the threaded knob 203 can be separated from the rear side of the housing 1, and the connecting plate 202 is separated from the engaging groove 205 by flipping the flip cover 201, and the flip cover 201 and the sealing ring 204 are separated from the square groove 206, so that the inside of the air duct can be maintained and repaired, reducing the possibility of blockage inside the air duct.
