Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-6 , the present utility model provides a technical solution: a quick-connect galvanized air duct, including a first air duct 1 and a second air duct 2. One end of the first air duct 1 is connected to the first joint 3, and one end of the second air duct 2 is connected to the second joint 4. A plurality of groups of grooves 31 are provided on the first joint 3. A card joint assembly 32 is arranged inside the groove 31. A sliding ring 33 is sleeved on the outside of the first joint 3 in a sliding manner. A plurality of groups of positioning chutes 34 are provided on the inner side surface of the first joint 3. A plurality of groups of positioning ribs 41 and card slots 42 are provided on the outer side surface of the second joint 4, and the card joint assembly 32 and the groove 31 are connected by a spring 312.

[0026] Among them, the assembly between the first air duct 1 and the second air duct 2 is realized through the first joint 3 and the second joint 4. During assembly, the positioning rib 41 of the second joint 4 of the second air duct 2 is slidably inserted into the positioning chute 34 of the first joint 3 of the first air duct 1 for positioning. As Figure 5 shown, at this time, the groove 31 and the card joint assembly 32 of the first joint 3 are aligned with the card slot 42 of the second joint 4;

[0027] After alignment, a certain external force is applied to the sliding ring 33 to drive the sliding ring 33 to slide relative to the first joint 3. As Figure 6As shown, during the sliding process, the inner side of the sliding ring 33 presses against the upper connector 321 of the connector assembly 32. The spring 312 below the upper connector 321 is compressed. The upper connector 321 drives the connecting rod 322 and the lower connector 323 at its lower end to move downward, and the lower connector 323 is snapped into the snap groove 42 of the second connector 4, realizing the locking between the second connector 4 and the first connector 3, that is, completing the quick connection assembly between the first air duct 1 and the second air duct 2.

[0028] Among them, the connector assembly 32 includes an upper connector 321 and a lower connector 323, and the upper connector 321 and the lower connector 323 are connected by a connecting rod 322. When the upper connector 321 of the connector assembly 32 is driven by an external force, it drives the connecting rod 322 at its lower end, and drives the lower connector 323 to move synchronously through the connecting rod 322.

[0029] Among them, when it is necessary to disassemble the first air duct 1 and the second air duct 2, apply a certain external force to slide the sliding ring 33. The sliding ring 33 moves away from the upper part of the connector assembly 32. The spring 312 relies on its own resilience to drive the upper connector 321 of the connector assembly 32 to move upward and reset. The upper connector 321 drives the lower connector 323 to move upward and reset synchronously through the connecting rod 322. Under the action of the resilience of the spring 312, the lower connector 323 moves out of the snap groove 42 of the second connector 4 and returns to the state as Figure 5 shown. At this time, there is no connection between the second connector 4 and the first connector 3, that is, the disassembly of the first air duct 1 and the second air duct 2 is realized.

[0030] Among them, the assembly and disassembly methods of the first air duct 1 and the second air duct 2 are both realized by manually driving the sliding ring 33 to slide. By pressing the connector assembly 32 with the sliding ring 33, the lower connector 323 is snapped into the snap groove 42 of the second connector 4, realizing the quick assembly between the second connector 4 and the first connector 3. During disassembly, drive the sliding ring 33 to move away from the upper part of the connector assembly 32. Under the action of the resilience of the spring 312, the lower connector 323 moves out of the snap groove 42 of the second connector 4, realizing the quick disassembly between the second connector 4 and the first connector 3.

[0031] Among them, an arc surface is provided on the upper part of the upper connector 321, an arc surface is provided on the lower part of the lower connector 323, and both the upper connector 321 and the lower connector 323 are slidably connected to the groove 31. Driven by an external force, the connector assembly 32 can slide along the axis direction of the groove 31.

[0032] Among them, a fixing ring 311 is fixedly arranged on the inner side surface of the groove 31. One end of the spring 312 is fixedly connected to the fixing ring 311, and the other end of the spring 312 is fixedly connected to the upper clamping joint 321. When the clamping joint assembly 32 moves downward under the action of an external force, the spring 312 is compressed. When the external force disappears, the clamping joint assembly 32 moves upward and resets under the action of the resilience of the spring 312.

[0033] Among them, a conical surface 331 is arranged on the inner side surface of the sliding ring 33. The arrangement of the conical surface 331 enables the sliding ring 33 to apply an external force to the clamping joint assembly 32 and slide to the periphery of the clamping joint assembly 32.

[0034] Among them, there are four groups of positioning convex strips 41, and the four groups of positioning convex strips 41 are arranged at equal intervals along the circumferential direction of the second joint 4. There are four groups of positioning chutes 34, and the four groups of positioning chutes 34 are arranged at equal intervals along the circumferential direction of the first joint 3, and the positioning convex strips 41 and the positioning chutes 34 are correspondingly arranged.

[0035] Among them, the four groups of positioning chutes 34 and the four groups of positioning convex strips 41 are correspondingly arranged. When assembling the first air duct 1 and the second air duct 2, the quick positioning and alignment of the first joint 3 of the second air duct 2 and the second joint 4 of the second air duct 2 can be realized.

[0036] Among them, there are four groups of clamping grooves 42, and the four groups of clamping grooves 42 are arranged at equal intervals along the circumferential direction of the second joint 4.

[0037] Among them, there are four groups of grooves 31 and four groups of clamping joint assemblies 32, and the four groups of grooves 31 and the four groups of clamping joint assemblies 32 are arranged at equal intervals along the circumferential direction of the first joint 3, and the grooves 31, the clamping joint assemblies 32 and the clamping grooves 42 are correspondingly arranged.

[0038] Among them, one group of groove 31, clamping joint assembly 32 and clamping groove 42 form a locking position, and the four groups of grooves 31, clamping joint assemblies 32 and clamping grooves 42 together form four locking positions, realizing locking assembly from multiple directions and improving the connection stability between the first joint 3 and the second joint 4, that is, improving the connection stability between the first air duct 1 and the second air duct 2.

[0039] Among them, the positioning convex strip 41 is slidably connected to the positioning chute 34. When assembling the first air duct 1 and the second air duct 2, the positioning convex strip 41 of the second air duct 2 slides and is embedded into the positioning chute 34 of the first joint 3 to achieve positioning.

[0040] Working principle: During assembly, the positioning rib 41 of the second joint 4 of the second air duct 2 is slidably inserted into the positioning chute 34 of the first joint 3 of the first air duct 1 for positioning. At this time, the groove 31 and the clamping joint assembly 32 of the first joint 3 are aligned with the clamping groove 42 of the second joint 4. After alignment, a certain external force is applied to the sliding ring 33 to drive the sliding ring 33 to slide relative to the first joint 3. The inner side surface of the sliding ring 33 presses the upper clamping joint 321 of the clamping joint assembly 32 during the sliding process. The spring 312 at the lower part of the upper clamping joint 321 is compressed. The upper clamping joint 321 drives the connecting rod 322 and the lower clamping joint 323 at its lower end to move downward, and the lower clamping joint 323 is clamped into the clamping groove 42 of the second joint 4, realizing the locking between the second joint 4 and the first joint 3 and completing the assembly. During disassembly, a certain external force is applied to slide the sliding ring 33, and the sliding ring 33 moves away from the upper part of the clamping joint assembly 32. The spring 312 drives the upper clamping joint 321 of the clamping joint assembly 32 to move upward and reset by its own resilience. The upper clamping joint 321 drives the lower clamping joint 323 to move upward and reset synchronously through the connecting rod 322. The lower clamping joint 323 moves out of the clamping groove 42 of the second joint 4 under the action of the resilience of the spring 312, releasing the locking between the second joint 4 of the second air duct 2 and the first joint 3 of the first air duct 1 and realizing disassembly.
