Description
Technical Field
[0001] This utility model relates to the field of elevator air conditioning technology, and in particular to a retractable elevator air conditioning outlet duct. Background Technology
[0002] The air outlet duct of an elevator air conditioner is a key component in the elevator air conditioning system responsible for transporting hot and cold air. Its design, selection and installation directly affect the cooling efficiency of the air conditioner, the comfort inside the car and the stability of the system. Its main function is to accurately deliver the cold air generated by the elevator air conditioning unit to the elevator car according to the design requirements, so as to ensure that the temperature regulation of the air inside the car is uniform and effective.
[0003] To minimize heat loss and prevent condensation during installation, elevator air conditioning ducts typically require insulation. Installation must ensure secure connections and proper sealing to prevent leaks. Regular cleaning is necessary to remove dust and debris, preventing blockages and ensuring proper ventilation. Additionally, the ducts must be inspected for damage, deformation, or leaks, and repaired or replaced as needed. The inner shell of the air outlet contains filters that must be replaced according to a prescribed schedule to maintain air quality. This process can be time-consuming when disassembling the ducts. Furthermore, the limited space at the top of elevators, coupled with other components, significantly hinders the installation and disassembly of the air conditioning unit and ducts. Therefore, a retractable elevator air conditioning duct system is proposed to address these issues. Utility Model Content

Detailed Implementation
[0032] 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.
[0033] Reference Figures 1-3This utility model provides an embodiment of a retractable elevator air conditioner air outlet duct, including a body 1. The air conditioner body 1 contains components such as a refrigeration compressor, condenser, capillary tube, and evaporator, all of which are existing technologies and not improvements of this application, and will not be described in detail here. A return air inlet 2 is fixedly connected to the outside of the body 1. The air in the elevator can be filtered and cooled through the return air inlet 2 before being discharged from the air outlet. A fixing plate 3 is installed on the outside of the body 1. A fixing mechanism is installed inside the fixing plate 3. An air outlet pipe 12 is fixedly connected to the outside of the fixing plate 3. The air outlet pipe 12 is quickly fixedly installed on the outside of the body 1 through the fixing plate 3. A rotating component is installed on the outside of the air outlet pipe 12. A storage component is installed on the outside of the rotating component. The storage component can quickly extend and retract the air outlet pipe 12 for easy carrying and use.
[0034] The fixing mechanism includes a pushing component and a snap-fit component. The snap-fit component includes a snap-fit block 8, which is slidably connected inside the fixing plate 3. A snap-fit groove 11 is provided on the outer side of the body 1, and the snap-fit block 8 snaps into the snap-fit groove 11. When the fixing plate 3 is brought close to the body 1, the body 1 presses the snap-fit block 8 to move. A fixing rod 9 is fixedly snapped into the outer side of the snap-fit block 8. A spring 10 is installed inside the fixing plate 3, and one end of the spring 10 is installed at the end of the fixing rod 9. When the fixing plate 3 is installed, the snap-fit block 8 is first pressed and moved, which simultaneously drives the fixing rod 9 to press the spring 10. When the body 1 and the fixing plate 3 are in contact, the spring 10 pushes the fixing rod 9 to drive the snap-fit block 8 to reset and snap into the snap-fit groove 11, so that the fixing plate 3 and the body 1 are tightly in contact, and the fixing plate 3 drives the air outlet pipe 12 to be installed quickly. To prevent gas leakage, a sealing ring can be installed between the fixing plate 3 and the body 1 to enhance the sealing effect.
[0035] The pushing component includes a button 4, which is slidably connected inside the fixed plate 3. The fixed plate 3 has a groove 7 inside, and the button 4 is slidably connected inside the groove 7. A slider 5 is fixedly connected to the outside of the button 4. A limiting groove 6 is opened inside the fixed plate 3, and the slider 5 is slidably connected inside the limiting groove 6. The limiting groove 6 limits the button 4 through the slider 5 to prevent the button 4 from falling off. The outside of the button 4 is tightly fitted with the end of the locking block 8. When the button 4 is pressed and slid, the locking block 8 can be pushed to move. The moving locking block 8 drives the fixed rod 9 to compress the spring 10. At this time, the locking block 8 separates from the locking groove 11, and the fixed plate 3 can be removed to replace and repair the body 1 and the air outlet pipe 12, greatly improving portability and work efficiency.
[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The rotating assembly includes a fixed block 14, which is fixedly connected to the outside of the air outlet duct 12. A fixed shaft 15 is fixedly connected to the middle of the fixed block 14, and a rotating block 16 is rotatably connected to the outer periphery of the fixed shaft 15. The rotating block 16 rotates along the outer periphery of the fixed shaft 15. A clamping plate 17 is fixedly connected to the outer side of the rotating block 16. The rotating block 16 drives the clamping plate 17 to rotate. The storage assembly includes a fixed shaft 18, which is fixedly connected to the middle of the clamping plate 17. The storage assembly rotates with the rotating block 16 via the clamping plate 17, allowing for flexible angle adjustment. A clamping plate 20 is rotatably connected to the outer periphery of the fixed shaft 18. A torsion spring 19 is sleeved on the outer periphery of the fixed shaft 18. The two ends of the torsion spring 19 are respectively installed on the inner sides of the clamping plate 17 and the clamping plate 20. The clamping plate 17 and the clamping plate 20 are connected by the torsion spring 19 and the clamping plate 20. The fixed shaft 18 is used for clamping. The end of the clamping plate 20 is fixedly connected to the insert block 21. The inner side of the clamping plate 20 is provided with the insertion hole 22. The insert block 21 is engaged with the insertion hole 22. The air outlet pipe 12 can be retracted and stored by engaging the insert block 21 of the clamping plate 20 with the insertion hole 22 of the previous clamping plate 20. The outer side of the air outlet pipe 12 is fixedly connected to the buckle 13. The insert block 21 is engaged with the buckle 13. When the air outlet pipe 12 needs to be installed, the clamping plate 17 and the clamping plate 20 can be opened to separate the insert block 21 from the buckle 13 and the insertion hole 22, and the air outlet pipe 12 can be unfolded to facilitate the quick installation of the air outlet pipe 12. After the installation is completed, the length of the air outlet pipe 12 can be adjusted by engaging the insert block 21 with the buckle 13 and the insertion hole 22, which reduces the space occupied on the top of the elevator, reduces damage to the elevator, and greatly improves convenience and safety.
[0037] Working principle: First, press the clamping plates 17 and 20 to compress the torsion spring 19, causing the insert 21 to separate from the insertion hole 22 and the buckle 13, extending the stored air outlet pipe 12. Then, bring the fixing plate 3 close to the body 1, and the body 1 presses the locking block 8 to move. When the fixing plate 3 is in place, the locking block 8 rebounds under the action of the spring 10, and the locking block 8 quickly engages with the locking slot 11, causing the fixing plate 3 to quickly and firmly fix the air outlet pipe 12 on the outside of the body 1. After the air outlet pipe 12 is installed, the air outlet pipe 12 is opened. By pressing the clamp 17 and clamp 20 again to compress the torsion spring 19, the insert 21 engages with the buckle 13 and the socket 22, adjusting the length of the air outlet 12 and retrieving the excess air outlet 12 to reduce the space occupied on the top of the elevator. This also reduces the vibration of the excessively long pipe during elevator use, which can generate a lot of noise. After a certain period of use, press the button 4 to push the clamp 8 away from the slot 11, remove the air outlet 12 for replacement, and inspect the machine body 1.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
