Description

Technical Field

[0001] This utility model relates to the field of air outlet technology, and in particular to an air outlet that is easy to disassemble and assemble. Background Technology

[0002] Central air conditioning is a centralized cooling and heating system. It utilizes a single main unit connected to multiple terminals via ductwork or chilled / hot water pipes to regulate the indoor temperature of each room. This system employs ductwork air delivery, requiring only one main unit to control the temperature of multiple rooms. It can also introduce fresh air, significantly improving indoor air quality and effectively preventing air conditioning-related illnesses. Central air conditioning systems offer centralized cooling and heating, are not only economical and energy-efficient but also save space and simplify management. Its operating principle is simple: air is delivered to each room through ductwork and then exhausted through vents in the ceiling, achieving uniform temperature regulation and indoor air circulation.

[0003] The applicant obtained the following prior art through searching, specifically, patent CN213395843U discloses a central air conditioning vent grille, including an outer frame and several grille strips arranged parallel to each other within the outer frame. One end of each grille strip is hinged to the inner wall of the outer frame. A fixing block is provided at the end of each grille strip away from its hinge point. A connecting block is provided on the side wall of the fixing block away from the grille strip. Grooves are spaced apart on the side wall of the outer frame near the fixing block. The connecting blocks are embedded in the grooves. Magnetic block one and magnetic block two are respectively provided at the bottom of the grooves and on the connecting blocks. When the connecting blocks are embedded in the grooves, magnetic block one and magnetic block two attract each other. This utility model allows users to easily clean the grille strips, preventing dust accumulation on the grille strips from negatively affecting the normal operation of the central air conditioning system.

[0004] As can be seen from the patent above, although this type of central air conditioning vent grille makes it convenient for users to clean the grille strips and prevent the dust accumulated on the grille strips from adversely affecting the normal use of the central air conditioning, in actual use, since the vents are usually installed on the ceiling or suspended ceiling of the room, their installation position is relatively high. When cleaning the vents, users need to use ladders, scaffolding and other auxiliary tools, which makes the operation troublesome, reduces cleaning efficiency, increases cleaning difficulty, and poses a safety hazard of falling from height.

[0029] Example 1:

[0030] This utility model proposes an air outlet that is easy to disassemble and assemble.

[0031] In one embodiment of this utility model, an air outlet that is easy to assemble and disassemble is set on the top of the room and connected to the air conditioning duct. It includes a fixed frame 1, a movable frame 2, a horizontal grid plate 3, a vertical grid plate 4, a hoisting mechanism, and a limiting mechanism. The fixed frame 1 is set at a reserved position on the top of the room. The hoisting mechanism is set on the side wall of the fixed frame 1 and is detachably connected to the movable frame 2. The hoisting mechanism is used to drive the movable frame 2 to move up and down. A groove 5 is opened in the movable frame 2. The horizontal grid plate 3 and the vertical grid plate 4 are stacked in the groove 5. The limiting mechanism is set near the top of the groove 5 and is used to stop the horizontal grid plate 3 and the vertical grid plate 4.

[0032] Specifically, this utility model provides an easily detachable air outlet. During use, by fixing the frame 1 to a pre-reserved position on the room's ceiling or suspended ceiling and connecting it to the air conditioning duct, it can discharge cold / hot air generated by the air conditioning system. Further, as... Figures 1 to 4As shown, since the hoisting mechanism is located on the side wall of the fixed frame 1 and detachably connected to the movable frame 2, the hoisting mechanism can be a winch or similar device as used in existing technologies. This allows the hoisting mechanism to drive the movable frame 2 to move up and down relative to the fixed frame 1. Simultaneously, since the groove 5 of the movable frame 2 is provided with stacked horizontal gratings 3 and vertical gratings 4, when the cold or hot air generated by the air conditioning system passes through the horizontal gratings 3 and vertical gratings 4, the airflow can be diverted by the horizontal gratings 3 and vertical gratings 4, thereby changing the airflow diffusion range and achieving a more uniform airflow distribution. When the user needs to clean the horizontal gratings 3 and vertical gratings 4, the hoisting mechanism can lower the movable frame 2 to a position accessible to the user. This eliminates the need for ladders, scaffolding, or other auxiliary tools for cleaning, simplifying the operation, improving cleaning efficiency, reducing cleaning difficulty, and preventing the safety hazard of users falling from heights during cleaning. In addition, it is worth noting that since the movable frame 2 has a groove 5, by stacking the horizontal grid plate 3 and the vertical grid plate 4 in the groove 5, the horizontal grid plate 3 and the vertical grid plate 4 can be stably installed and limited, which effectively avoids the horizontal grid plate 3 and the vertical grid plate 4 from falling accidentally during the lifting and lowering process of the movable frame 2, thus improving the safety of this utility model.

[0033] Understandably, since a limiting mechanism is provided near the top of the groove 5, the limiting mechanism can be a threaded connection or the like in the prior art. The threaded connection structure is simple and easy to disassemble and assemble. This not only makes it easier for users to pick up the horizontal grid plate 3 and the vertical grid plate 4 in the groove 5 and facilitates cleaning operations, but also allows the limiting mechanism to stop and limit the horizontal grid plate 3 and the vertical grid plate 4, further improving the stability of the horizontal grid plate 3 and the vertical grid plate 4 in the groove 5, making it safe and reliable to use.

[0034] In one embodiment, the hoisting mechanism includes a plurality of lifting components 6, which are evenly and spaced along the outer wall of the fixed frame 1. Each of the lifting components 6 includes a base 7, a drive component 8, a rotating wheel 9, a traction rope 10, and a hook 11. The base 7 is detachably mounted on the fixed frame 1. The drive component 8 is disposed on the base 7 and is used to drive the rotating wheel 9 to rotate. The traction rope 10 is wound around the rotating wheel 9, and one end of the traction rope 10 is connected to the hook 11. The hook 11 is used to detachably connect to the movable frame 2.

[0035] Specifically, such as Figures 1 to 4As shown, since several lifting components 6 in the hoisting mechanism are evenly and spaced along the outer wall of the fixed frame 1, the movable frame 2 can be hoisted at multiple points, thereby ensuring the stability and balance of the movable frame 2 during the lifting process. Furthermore, the base 7 of the lifting component 6 can be detachably installed with the fixed frame 1 by a threaded connection, which facilitates the disassembly, replacement or maintenance of the lifting component 6. At the same time, since the driving component 8 is set on the base 7 and is used to drive the rotating wheel 9 to rotate, and the traction rope 10 is wound around the rotating wheel 9, the driving component 8 can be a motor in the prior art. When the driving component 8 runs and drives the rotating wheel 9 to rotate, the traction rope 10 falls off or wraps around the rotating wheel 9, thereby driving the hook 11 and the movable frame 2 to move up and down relative to the fixed frame 1. The structural design is simple and reasonable. Understandably, by opening a lifting hole on the movable frame 2 and enabling the hook 11 to engage with the lifting hole, the hook 11 and the movable frame 2 can be detachably connected. The disassembly and assembly method is convenient and facilitates the user to pick up and put down the movable frame 2, the horizontal grid plate 3 and the vertical grid plate 4.

[0036] In another embodiment, buckles 12 are detachably installed on the movable frame 2 at positions corresponding to several lifting components 6, and the buckles 12 are used to engage with the hooks 11. Specifically, as shown in the figure... Figure 2 and Figure 3 As shown, the buckle 12 and the movable frame 2 can be detachably connected by a threaded connection, which facilitates the disassembly and replacement of the buckle 12. Furthermore, the buckle 12 can prevent the hook 11 from accidentally falling off during the lifting process, improving safety. The snap-fit ​​between the hook 11 and the buckle 12 allows users to quickly connect and disconnect the lifting assembly 6 and the movable frame 2, making operation simple and convenient.

[0037] In one embodiment, such as Figure 1 and Figure 2As shown, a through hole is provided on the outer wall of the movable frame 2. The limiting mechanism includes an elastic element 13 and a locking pin 14. The two ends of the elastic element 13 are connected to the outer wall of the movable frame 2 and the locking pin 14, respectively. One end of the locking pin 14 passes through the through hole and is used to abut against the horizontal grid plate 3 or the vertical grid plate 4. Specifically, after one end of the locking pin 14 passes through the through hole, it extends into the groove 5. At this time, the elastic element 13 can ensure that the end of the locking pin 14 extending into the groove 5 is always above the horizontal grid plate 3 or the vertical grid plate 4, thereby achieving the blocking and limiting of the horizontal grid plate 3 and the vertical grid plate 4. The structural design is simple and reasonable. Furthermore, when it is necessary to remove the horizontal grid plate 3 or the vertical grid plate 4 from the groove 5, the user can pull the locking pin 14 and make the elastic element 13 be in a stretched state. At this time, the locking pin 14 is released from the blocking and limiting of the horizontal grid plate 3 or the vertical grid plate 4, and the user can remove the horizontal grid plate 3 or the vertical grid plate 4. The operation is convenient. Compared with the existing technology where the horizontal grid plate 3 or the vertical grid plate 4 is installed with the movable frame 2 by threaded connection, this utility model does not require other auxiliary disassembly and assembly tools, which improves the convenience of disassembly and assembly and facilitates cleaning and maintenance.

[0038] In one embodiment, such as Figure 1 and Figure 2 As shown, locking holes 15 are provided on the horizontal grid plate 3 and the vertical grid plate 4 at the positions corresponding to the through holes, allowing the locking pin 14 to extend into them. Understandably, after one end of the locking pin 14 extends into the groove 5, it can be inserted and engaged with the locking hole 15, thereby improving the limiting effect on the horizontal grid plate 3 and the vertical grid plate 4, and ensuring the stability of the horizontal grid plate 3 or the vertical grid plate 4 in the groove 5. It should be noted that, under normal use, i.e., when the movable frame 2 is not in the lowered state, the bottom of the fixed frame 1 extends into the groove 5 and is inserted into the groove 5. The bottom surface of the fixed frame 1 abuts against the top surface of the horizontal grid plate 3 or the vertical grid plate 4. Under the action of the hoisting mechanism, the fixed frame 1 can tighten and limit the horizontal grid plate 3 and the vertical grid plate 4, preventing the horizontal grid plate 3 and the vertical grid plate 4 from vibrating or shaking and producing abnormal noise during use. At the same time, through the insertion and cooperation of the locking hole 15 and the locking pin 14, it is possible to ensure that the bottom surface of the fixed frame 1 is tightly abutted against the top surface of the horizontal grid plate 3 or the vertical grid plate 4 while ensuring that the locking pin 14 limits the horizontal grid plate 3 and the vertical grid plate 4. The structural design is simple and reasonable.

[0039] In one embodiment, the elastic element 13 is a spring, which is sleeved on the locking pin 14. An annular protrusion 16 for blocking the elastic element 13 is formed on the outer wall of the movable frame 2 at the position corresponding to the through hole. Specifically, as shown... Figure 1 and Figure 2As shown, the elastic element 13 can be a spring from the prior art. Springs have the characteristics of compact structure, easy material sourcing, and large elastic deformation force, so that when the user does not pull out the locking pin 14, the locking pin 14 can always be inserted into the locking hole 15 under the action of the elastic element 13, thereby ensuring the limiting effect on the transverse grid plate 3 and the longitudinal grid plate 4. Furthermore, the annular protrusion 16 not only ensures the stability of the elastic element 13 during the rebound movement, but also effectively avoids the elastic element 13 being easily affected by external impurities or other factors, thus affecting its use.

[0040] In one embodiment, specifically, as Figure 1 and Figure 2 As shown, an annular flange 17 is formed on the outer wall of the movable frame 2 at the position corresponding to the groove opening of the groove 5. The groove opening of the groove 5 is set to expand outward from bottom to top, which facilitates the insertion of the fixed frame 1 into the groove 5 and improves the smoothness of the insertion and engagement between the fixed frame 1 and the groove 5.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
