Description

Technical Field

[0001] This utility model belongs to the field of central air conditioning technology, specifically relating to a central air conditioning air supply device. Background Technology

[0002] Central air conditioning vents are terminal devices in a central air conditioning system used for supplying and returning air; they are a type of air distribution equipment. Supply vents deliver cooled or heated air into the room, while return vents draw indoor air back in via an internal fan. This creates a cycle of air circulation within the room, continuously cooling or heating the air through this process.

[0003] Currently, air supply ducts of central air conditioning systems often require the installation of air guide plates. A common installation method involves placing the air guide plate at the duct's mounting position, using a screwdriver to thread screws through the guide plate's mounting holes into the duct's threaded holes, and relying on the screws' tightening force to fix the guide plate to the duct. While this method is secure, disassembly is extremely cumbersome. Alternatively, the guide plate's clips can be aligned with the slots on the duct, and then the guide plate can be gently pressed to engage the clips. However, this fixing method lacks stability, and the guide plate is prone to wobbling during air supply, thus affecting the air delivery effect. To address these issues, this application proposes a central air conditioning air supply device. Utility Model Content

[0010] A fixing rod is fixedly provided on the air guide plate. Two inclined grooves are opened at one end of the fixing rod, and two V-shaped limiting grooves are symmetrically opened on its outer wall.

[0011] The fixing box has a first clearance hole on one side, and sliding rods pass through both sides of the fixing box. Each of the two sliding rods has a U-shaped connecting bracket at one end inside the fixing box.

[0012] An installation rod is fixed between the U-shaped connecting frames, and an arc-shaped limiting plate for embedding into the V-shaped limiting groove is fixed on the outer wall of the installation rod;

[0013] The outer wall of the slide rod is fitted with a return spring, and its two ends abut against the side wall of the U-shaped connecting frame and the inner wall of the fixing box, respectively.

[0014] Preferably, a support rod is provided on one side of the U-shaped connecting frame, and one end of the support rod extends through the side wall of the fixing box to the outside.

[0015] Preferably, guide holes are provided on both sides of the outer wall of the fixing box, and the two ends of the mounting rod pass through the two guide holes respectively, and can move back and forth along the length direction of the guide holes.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example

[0035] Please see Figures 1-9This utility model provides the following technical solution: a central air conditioning air supply device, including an air supply duct 1 and an air guide plate 3 disposed on the air supply duct 1.

[0036] A connecting frame 2 is fixedly connected to one side of the air supply duct 1, and two handles 4 are symmetrically arranged on one side of the air guide plate 3;

[0037] Two fixing boxes 6 are symmetrically arranged on one side of the connecting frame 2;

[0038] Two sets of limiting components 100 are respectively located in the internal cavities of the two fixing boxes 6 to achieve a detachable connection between the air guide plate 3 and the air supply pipe 1. In use, first align the air guide plate 3 with the connecting frame 2, and use the handle 4 to easily hold the air guide plate 3 for operation. Then, using the two sets of limiting components 100, the air guide plate 3 and the air supply pipe 1 can be quickly and detachably connected under the action of the internal cavities of the fixing box 6. When it is necessary to remove the air guide plate 3 for cleaning or maintenance, operate the limiting components 100 to release the fixation of the air guide plate 3. The air guide plate 3 can be easily removed from the air supply pipe 1 using the handle 4. The operation is simple and the connection is stable, effectively avoiding the problems of cumbersome disassembly and poor stability of traditional screw fixing and buckle fixing, thus improving the convenience and reliability of the equipment.

[0039] Preferably, by Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, the limiting component 100 includes a second clearance hole 9 formed on the connecting frame 2;

[0040] A fixing rod 5 is fixedly provided on the air guide plate 3. Two inclined grooves 108 are opened at one end of the fixing rod 5, and two V-shaped limiting grooves 109 are symmetrically opened on its outer wall.

[0041] A first clearance hole 8 is provided on one side of the fixing box 6, and slide rods 101 pass through both sides of the fixing box 6. A U-shaped connecting bracket 102 is provided at one end of each slide rod 101 inside the fixing box 6.

[0042] A mounting rod 103 is fixed between the U-shaped connecting brackets 102, and an arc-shaped limiting plate 104 for embedding into the V-shaped limiting groove 109 is fixed on the outer wall of the mounting rod 103.

[0043] A return spring 105 is sleeved on the outer wall of the slide bar 101, and its two ends abut against the side wall of the U-shaped connecting frame 102 and the inner wall of the fixing box 6 respectively. When in use, the operator holds the handles 4 on both sides of the air guide plate 3, aligns the air guide plate 3 with the installation position of the connecting frame 2, and makes the fixing rod 5 on the air guide plate 3 pass through the first clearance hole 8 on one side of the fixing box 6 and the second clearance hole 9 on the connecting frame 2 in sequence, and gradually extend into the internal cavity of the fixing box 6.

[0044] During the process of the fixed rod 5 entering the fixed box 6, the two inclined grooves 108 at its end will contact the arc-shaped limiting plate 104 on the outer wall of the mounting rod 103. As the fixed rod 5 continues to advance, the inclined surface of the inclined groove 108 will squeeze the arc-shaped limiting plate 104 on both sides, forcing the arc-shaped limiting plate 104 to drive the mounting rod 103 and the U-shaped connecting frame 102 to move along the slide rod 101 to both sides of the fixed box 6. At this time, the return spring 105 on the outer wall of the slide rod 101 is compressed and stores elastic potential energy.

[0045] When the fixing rod 5 is fully inserted into the fixing box 6, and the V-shaped limiting groove 109 on the outer wall of the fixing rod 5 is aligned with the position of the arc-shaped limiting plate 104, the reset spring 105 releases elastic potential energy, pushing the U-shaped connecting frame 102 and the mounting rod 103 to reset, so that the arc-shaped limiting plate 104 is precisely embedded in the V-shaped limiting groove 109. Through the interlocking action of the arc-shaped limiting plate 104 and the V-shaped limiting groove 109, a stable connection between the air guide plate 3 and the connecting frame 2 (i.e., the air supply pipe 1) is achieved.

[0046] When it is necessary to disassemble the air guide plate 3, the operator holds the handle 4 and pulls the air guide plate 3 outward. The fixing rod 5 moves synchronously with the air guide plate 3. At this time, the inner wall of the V-shaped limiting groove 109 will squeeze the arc-shaped limiting plate 104, which will force the arc-shaped limiting plate 104 to move to both sides and compress the return spring 105. When the arc-shaped limiting plate 104 is completely separated from the V-shaped limiting groove 109, the fixing rod 5 can be smoothly pulled out from the first clearance hole 8 and the second clearance hole 9, thus completing the disassembly of the air guide plate 3.

[0047] The entire installation and disassembly process requires no tools and is achieved through the automatic engagement and disengagement of the mechanical structure. This ensures the stability of the connection (the contact surfaces of the V-shaped limiting groove 109 and the arc-shaped limiting plate 104 can withstand a certain amount of tension, preventing the air guide plate 3 from shaking during air supply) and simplifies the assembly and disassembly steps, solving the problems of cumbersome disassembly and easy loosening of traditional screw fixing and buckle fixing.

[0048] Preferably, by Figure 1 , Figure 7 , Figure 8 and Figure 9As shown, in this embodiment, a support rod 110 is provided on one side of the U-shaped connecting frame 102, and one end of the support rod 110 extends through the side wall of the fixing box 6 to the outside; this can increase the stability of the U-shaped connecting frame 102 and prevent the U-shaped connecting frame 102 from shaking or shifting during movement.

[0049] Preferably, by Figure 1 , Figure 7 and Figure 9 As shown, in this embodiment, guide holes 107 are provided on both sides of the outer wall of the fixing box 6. The two ends of the mounting rod 103 pass through the two guide holes 107 respectively and can move back and forth along the length direction of the guide holes 107. This can guide and limit the movement of the mounting rod 103, ensure the stability of the mounting rod 103 during the movement, and further improve the accuracy of the engagement between the arc-shaped limiting plate 104 and the V-shaped limiting groove 109.

[0050] Preferably, by Figure 1 , Figure 7 and Figure 9 As shown, in this embodiment, the U-shaped connecting frame 102 is provided with a support member 106 inside, and the bottom surface of the support member 106 is fixedly connected to one side of the arc-shaped limiting plate 104. This can increase the structural strength of the arc-shaped limiting plate 104 and prevent the arc-shaped limiting plate 104 from deforming when squeezed, thus affecting its engagement with the V-shaped limiting groove 109. At the same time, the support member 106 can also make the arc-shaped limiting plate 104 more stable during movement and improve the smoothness of engagement.

[0051] Preferably, by Figure 1 and Figure 7 As shown, in this embodiment, the top of the fixing box 6 is provided with an opening 10; so that the top of the fixing rod 5 can be exposed from the opening 10 of the fixing box 6, avoiding obstruction of the fixing rod 5 during the insertion of the fixing box 6, and ensuring that the air guide plate 3 can be installed smoothly.

[0052] Preferably, by Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9As shown, in this embodiment, the combined length of the two sliding rods 101 and the U-shaped connecting frame 102 is 1-3 cm shorter than the length of the internal cavity of the fixing box 6; this allows a certain space to be reserved between the two arc-shaped limiting plates 104 so that the fixing rod 5 can smoothly pass through the space between the two arc-shaped limiting plates 104 using the inclined groove 108 at its end, and continue to push into the fixing box 6 until the V-shaped limiting groove 109 is aligned with the position of the arc-shaped limiting plate 104. At this time, the return spring 105 can have enough elastic potential energy to push the U-shaped connecting frame 102 and the mounting rod 103 to reset, so that the arc-shaped limiting plate 104 is accurately embedded in the V-shaped limiting groove 109, ensuring the stability of the connection between the air guide plate 3 and the air supply pipe 1.

[0053] Components not described in detail in this article are existing technologies.

[0054] The working principle and usage process of this utility model are as follows: When in use, the operator aligns the air guide plate 3 with the connecting frame 2 by holding the handle 4, so that the fixing rod 5 passes through the first clearance hole 8 and the second clearance hole 9 in sequence and gradually extends into the fixed box 6. During this process, the inclined groove 108 at the end of the fixing rod 5 contacts the arc-shaped limiting plate 104. As it is pushed forward, the inclined groove 108 squeezes the arc-shaped limiting plate 104 to move to both sides, driving the mounting rod 103 and the U-shaped connecting frame 102 to slide along the slide rod 101. At the same time, the return spring 105 is compressed. At this time, the mounting rod 103 moves smoothly along the guide hole 107, and the U-shaped connecting frame 102 is kept stable by the support rod 110 to avoid displacement.

[0055] When the fixing rod 5 is fully inserted into the fixing box 6, its top protrudes from the opening 10, the V-shaped limiting groove 109 is aligned with the arc-shaped limiting plate 104, the return spring 105 releases potential energy, pushes the U-shaped connecting frame 102 to reset, so that the arc-shaped limiting plate 104 is accurately embedded into the V-shaped limiting groove 109 under the reinforcement of the support member 106, and realizes a stable connection between the air guide plate 3 and the air supply pipe 1.

[0056] During disassembly, hold the handle 4 and pull it outward. The inner wall of the V-shaped limiting groove 109 will press the arc-shaped limiting plate 104 to move to both sides again, compressing the reset spring 105. After the arc-shaped limiting plate 104 is disengaged from the V-shaped limiting groove 109, the fixing rod 5 can be pulled out from the clearance hole to complete the disassembly.

[0057] The entire process relies on the automatic engagement and disengagement of the mechanical structure, requiring no tools. The tight fit between the V-shaped limiting groove 109 and the arc-shaped limiting plate 104 ensures the stability of air supply, while multiple sets of guide and support components ensure smooth operation, effectively solving the drawbacks of traditional installation methods.

[0058] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
