Description

Technical Field

[0001] The utility model belongs to the technical field of air ducts for air conditioners, and in particular relates to a combined air duct for an air conditioning system. Background Art

[0002] Air conditioning system refers to a system that uses artificial methods to process the temperature, humidity, cleanliness and air velocity of indoor air. It can enable certain places to obtain air with a certain temperature, humidity and air quality to meet the requirements of users and production processes and improve labor hygiene and indoor climate conditions. The air conditioning system needs to be equipped with air ducts to ensure air circulation.

[0003] The utility model patent with announcement number CN219222780U discloses a combined air duct for air supply of a three-constant system. In view of the use of an integral air supply duct in the disclosed technology, the length of the air supply duct cannot be conveniently adjusted during installation and construction, and the workload is large after later maintenance and disassembly, which increases the risk of air duct maintenance and installation. The use of a fixed air outlet is not conducive to the installation and use of the air duct during construction and installation and later maintenance, and reduces the practicality of the air duct. The precise positioning of the connecting pipe installation is ensured by the cooperation of the card slot and the card strip, the iron plate and the magnetic plate increase the card strip and the card slot to be tightly engaged, and the connecting holes at the four right angles of the connecting pipe are used to fix multiple connecting pipes with bolts. This not only increases the structural strength of the installation of multiple connecting pipes and facilitates length adjustment, but also facilitates the installation and later maintenance and disassembly of the connecting pipe. The air outlet angle is easy to adjust to ensure the stability of the air outlet direction of the corrugated pipe.

[0004] When assembling the combined air duct, it is necessary to use multiple sets of bolts and connecting plates to combine and fix the air ducts. The installation combination method is relatively troublesome, and multiple sets of bolts need to be tightened at the same time. At the same time, the internal size of the air duct is fixed, which makes it inconvenient to adjust the air outlet size and amount of the air duct, affecting the applicability of the device.

[0027] The combined mechanism includes a first connecting card plate 4, which is arranged on the top of the first air duct 1 and the second air duct 2, and a second connecting card plate 5 is installed at the bottom of the first connecting card plate 4. The tops of both sides of the second connecting card plate 5 are fixedly connected with fixing plates 6, and bolts 7 are rotatably connected inside the fixing plates 6. The bottoms of both sides of the first connecting card plate 4 are fixedly connected with connecting plates 8, and the top surface of the connecting plate 8 is provided with a first threaded hole 9, and the outer side of the bolt 7 is threadedly connected with a fixing bolt 12;

[0028] A fixing box 13 is fixedly connected to the top of the first air duct 1 , and an adjustment mechanism is provided between the first air duct 1 and the fixing box 13 .

[0029] As attached Figure 4 As shown, a positioning card plate 10 is fixedly connected to one side of the first air duct 1, and one end of the positioning card plate 10 passes through the sealing gasket 3 and extends to one side of the sealing gasket 3, so as to improve the sealing effect between the first air duct 1 and the second air duct 2 through the sealing gasket 3. A positioning card groove 11 is provided on the surface of one side of the second air duct 2, and the number of the positioning card plates 10 and the positioning card groove 11 are both set to two. The positioning card plates 10 are movably connected with each other, so as to facilitate the rapid positioning of the first air duct 1 and the second air duct 2, thereby improving the combination efficiency of the air ducts.

[0030] As attached Figure 1-3 As shown, the top of the bolt 7 passes through the fixing plate 6 and the connecting plate 8 in sequence and extends to the top of the connecting plate 8. The bolt 7 is threadedly connected to the first threaded hole 9, which facilitates the rotation of the bolt 7 to allow the first connecting clamp plate 4 and the second connecting clamp plate 5 to quickly fix the first air duct 1 and the second air duct 2.

[0031] As attached Figure 1 , 2As shown in , 4, the adjustment mechanism includes a lifting windshield plate 14, which is installed inside the fixing box 13. A through slide groove 19 is provided on the top surface of the first air duct 1, and both sides of the inner wall of the first air duct 1 are fixedly connected with limiting slide rails 20. The limiting slide rails 20 and the through slide groove 19 are slidably connected with the lifting windshield plate 14, which is convenient for limiting the lifting windshield plate 14 and preventing the lifting windshield plate 14 from rotating with the fixing knob 16 and the threaded rod 17. A second threaded hole 15 is provided on the top surface of the fixing box 13, and a threaded rod 17 is threadedly connected inside the second threaded hole 15.

The bearing 18 is installed on the top of the lifting windshield plate 14, and the height of the lifting windshield plate 14 can be adjusted by rotating the fixing knob 16, thereby adjusting the air outlet size and air volume of the first air duct 1.

[0032] Working principle of the utility model: when the first air duct 1 and the second air duct 2 are assembled and installed, the two positioning clamps 10 on one side of the first air duct 1 are first inserted into the two positioning clamp grooves 11 on the surface of one side of the second air duct 2 to complete the preliminary positioning connection of the first air duct 1 and the second air duct 2, and the first connecting clamp 4 and the second connecting clamp 5 are inserted into the connection of the first air duct 1 and the second air duct 2, so that the first threaded holes 9 on the surfaces of the connecting plates 8 on both sides of the first connecting clamp 4 are aligned with the bolts 7, and then the bolts 7 inside the fixing plate 6 are rotated. At the same time, due to the threaded connection between the bolts 7 and the first threaded holes 9, the bolts 7 are screwed into the first threaded holes 9, so that the first connecting clamp 4 and the second connecting clamp 5 are close to each other, and then the fixing bolts 12 are screwed into the outside of the bolts 7 and made to rest against the top of the connecting plate 8, so that the first connecting clamp 4 and the second connecting clamp 5 clamp and fix the connection of the first air duct 1 and the second air duct 2, thereby completing the combination of the first air duct 1 and the second air duct 2;

[0033] When adjusting the air outlet size of the first air duct 1, the threaded rod 17 is rotated by rotating the fixed knob 16. At the same time, due to the threaded connection between the threaded rod 17 and the second threaded hole 15, and the bearing 18 is installed between the threaded rod 17 and the lifting wind shield plate 14, the threaded rod 17 moves inside the second threaded hole 15, thereby driving the lifting wind shield plate 14 to slide inside the limiting slide rail 20, so that the opening distance between the lifting wind shield plate 14 and the first air duct 1 is adjusted, thereby completing the adjustment of the air outlet size.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
