Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning duct technology, specifically to an effective way to prevent loosening of automotive air conditioning ducts. Background Technology

[0002] Automotive air conditioning duct technology has developed alongside the widespread adoption of automobiles and the application of advanced technologies. The development of automotive air conditioning technology has gone through five stages: from basic to advanced, and from single-function to multi-function. The layout and duct design of automotive air conditioning systems are also crucial aspects of automotive air conditioning technology.

[0003] As living standards improve, people's demands for vehicles are becoming more personalized, and multi-functional commercial vehicles with versatile spaces are beginning to come into view. These vehicles can be used for business receptions, family use, RV conversions, etc., and offer excellent maneuverability and ample passenger space.

[0004] The car air conditioning duct is connected to the outlet duct of the car air conditioning unit, and its main function is to guide the air, so that the heated or cooled air generated in the car air conditioning unit is introduced into the passenger compartment.

[0005] The existing air conditioning duct installation structure consists of hook-shaped cantilever push-type buckles distributed around the duct opening. This connection can become loose, resulting in insecure installation and duct shaking. Furthermore, disassembly is inconvenient. The hook-shaped cantilever push-type buckle structure is also relatively soft, and the buckles are prone to breakage if the product is not properly placed during transportation. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, the technical problem to be solved by this utility model is to provide an effective way to prevent loosening of the automotive air conditioning duct. This solves the problem that the existing air conditioning duct installation structure uses hook-shaped cantilever push buckles distributed around the duct opening, which can lead to loose connections, insecure installation, duct shaking, and inconvenient disassembly. Furthermore, the hook-shaped cantilever push buckle structure is too soft, and the buckles are prone to breakage if the product is not properly placed during transportation.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] An effective anti-loosening automotive air conditioning duct includes a main body. Both sides of the air inlet of the main body are provided with a snap-fit ​​structure for connecting the main body to the external air duct. The snap-fit ​​structure includes a connecting frame connected to the main body and having an opening direction in the same direction as the air inlet. The inside of the connecting frame is fitted with a snap-fit ​​through a connecting shaft, and the inner end of the snap-fit ​​is connected to the inside of the connecting frame through a spring. The snap-fit ​​structure greatly improves the stability of the connection, effectively reduces the possibility of loosening and shaking after installation, and makes the installation more secure, preventing the air duct from shaking during installation.

[0009] One end of the main body is an air inlet, and the other end is an air outlet. The outer surface of the main body is covered with sponge, which can absorb some noise and vibration, further ensuring the stability of the main body. Mounting brackets are provided on both sides of the air outlet of the main body.

[0010] Furthermore, the buckle includes: a rotatable buckle rod and a buckle head connected to the top of the buckle rod. The buckle rod has a through hole in the middle position that mates with the connecting shaft. The front half of the buckle rod is located outside the connecting frame, and the rear half of the buckle rod is located inside the connecting frame. The buckle rod can rotate around the connecting shaft. The rotation of the buckle rod can drive the buckle head to move to achieve the opening and closing function.

[0011] Furthermore, the top of the latching rod is provided with a handle, and the position of the handle corresponds to the position of the latching head. When the user needs to install or disassemble the air conditioning duct, the user can grip the handle to rotate and open the latching rod, thereby adjusting the position of the latching head.

[0012] Furthermore, one side of the connecting frame is provided with a threaded hole, and a locking bolt is embedded in the threaded hole. One end of the locking bolt corresponds to the buckle rod. The locking bolt tightly presses against the buckle rod, effectively preventing the buckle rod from loosening, greatly improving the stability of the connection, effectively reducing loosening and shaking after installation, and making the installation more secure.

[0013] Furthermore, the buckle head has a triangular cross-section, and its outer surface is provided with anti-slip texture. The anti-slip texture can increase friction and indirectly improve stability.

[0014] Furthermore, the spring is located at the end of the buckle rod, with one end of the spring fixedly connected to the buckle rod and the other end of the spring fixedly connected to the side of the connecting frame and the main body.

[0015] Furthermore, the air inlet of the main body is provided with a connecting piece, which is fixedly connected to the main body. The outer side of the connecting piece is provided with anti-slip texture. By inserting the connecting piece into the air duct to be connected, the overall connection strength and stability are further improved, the occurrence rate of defective products is reduced, and the reliability during transportation is ensured.

[0016] Beneficial effects: Compared with the prior art, this application has the following advantages:

[0017] 1. This automotive air conditioning duct, designed to prevent loosening, features a novel snap-fit ​​structure. When connecting the duct to the desired duct, loosen the locking bolt to disengage it from the snap-fit ​​lever. The user then grips the handle and pulls the snap-fit ​​lever outwards, allowing the air conditioning duct to be properly inserted into the desired duct. Under the action of the spring, the snap-fit ​​lever rotates, causing the snap-fit ​​head to engage with the slot in the desired duct. Finally, the user tightens the locking bolt to firmly press the snap-fit ​​lever in place, effectively preventing loosening and significantly improving connection stability. This reduces the likelihood of loosening or shaking after installation, resulting in a more secure installation that prevents duct movement.

[0018] 2. The connecting frame of the snap-fit ​​structure of the automotive air conditioning duct is fixedly connected to the main body. In addition to the snap-fit ​​structure, the air conditioning duct also uses a connector to insert into the duct to be connected, which further improves the overall connection strength and stability, reduces the occurrence rate of defective products and ensures reliability during transportation.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, an effective anti-loosening automotive air conditioning duct includes a body 1. Both sides of the air inlet 4 of the body 1 are equipped with snap-fit ​​structures 6 for connecting the body 1 to external air ducts. The snap-fit ​​structures 6 allow the body to be secured to the external air duct to be connected, ensuring connection stability. The snap-fit ​​structure 6 includes a connecting frame 7 connected to the body 1 with its opening direction aligned with the air inlet 4. A snap 2 is embedded inside the connecting frame 7 via a connecting shaft 12, and the inner end of the snap 2 is connected to the inside of the connecting frame 7 via a spring 13. During installation, a user pulls the snap 2 outwards to allow the air conditioning duct to be properly inserted into the air duct to be connected. Then, under the action of the spring 13, the snap 2 rotates, causing the snap head 9 to insert into the slot of the air duct to be connected. Finally, a user tightens the locking bolt 14 to firmly press the snap 2, effectively preventing the snap 2 from loosening, greatly improving connection stability, effectively reducing loosening and shaking after installation, and ensuring a more secure installation without causing the air duct to shake.

[0025] One end of the main body 1 is an air inlet 4, and the other end of the main body 1 is an air outlet 5. The outer surface of the main body 1 is provided with a sponge 3, which can absorb a certain amount of noise and vibration, further ensuring the stability of the main body 1. The air outlet 5 of the main body 1 is provided with mounting brackets 16 on both sides, which can install the air conditioning duct at the required installation position.

[0026] like Figure 3 As shown, the buckle 2 includes: a rotatable buckle rod 8 and a buckle head 9 connected to the top of the buckle rod 8. The buckle rod 8 has a through hole 11 in the middle position that mates with the connecting shaft 12. The front half of the buckle rod 8 is located outside the connecting frame 7, and the rear half of the buckle rod 8 is located inside the connecting frame 7. The buckle rod 8 is a cuboid in shape, which facilitates the locking bolt 14 to be properly pressed against the buckle rod 8. The buckle rod 8 can rotate around the connecting shaft 12 as the center. The rotation of the buckle rod 8 can drive the buckle head 9 to move to achieve the opening and closing function.

[0027] The top back of the latching rod 8 is provided with a handle 10, and the position of the handle 10 corresponds to the position of the latching head 9. When the user needs to install or disassemble the air conditioning duct, the user can hold the handle 10 to rotate and open the latching rod 8, thereby adjusting the position of the latching head 9.

[0028] One side of the connecting frame 7 is provided with a threaded hole, and a locking bolt 14 is embedded in the threaded hole. One end of the locking bolt 14 corresponds to the buckle rod 8. The locking bolt 14 can rotate and move within the threaded hole of the connecting frame 7. When the user uses the buckle 2 to lock it in the slot, the locking bolt 14 can be used to move and push against the buckle rod 8 to prevent the buckle rod 8 from being rotated by external force. The locking bolt 14 tightly presses the buckle rod 8, effectively preventing the buckle rod 8 from loosening, greatly improving the stability of the connection, effectively reducing the loosening and shaking after installation, and making the installation more secure.

[0029] The clip head 9 has a triangular cross-section, which makes it easy to insert into the slots on both sides of the air duct to be installed. The outer surface of the clip head 9 is provided with anti-slip texture, which can increase friction and indirectly improve stability.

[0030] The spring 13 is located at the end of the buckle rod 8, and one end of the spring 13 is fixedly connected to the buckle rod 8. The other end of the spring 13 is fixedly connected to the side of the connecting frame 7 and the body 1. The fixed connection can improve the connection strength and stability, and ensure that the connection of the spring 13 will not loosen during long-term use. The spring 13 can cause the end of the buckle rod 8 to open outward, thereby causing the top of the buckle rod 8 and the buckle head 9 to retract inward.

[0031] The air inlet 4 of the main body 1 is provided with a connecting piece 15. The connecting piece 15 makes it easier and more accurate to insert the main body 1 into the air duct to be installed. The connecting piece 15 is fixedly connected to the main body 1. The fixed connection can improve the connection strength and stability. The outer side of the connecting piece 15 is provided with anti-slip texture. The anti-slip texture can improve a certain friction and improve the stability after connection.

[0032] This utility model provides an effective approach and implementation method for preventing loose automotive air conditioning ducts. There are many specific applications, and the above is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of this utility model, and these improvements should also be considered within the protection scope of this utility model.
