Description

Technical Field

[0001] This utility model relates to the field of spiral duct machine technology, specifically a spiral duct machine. Background Technology

[0002] Spiral duct machines all involve winding a certain width of coiled material into a spiral-shaped duct. The coiled material is fed into the crimping machine through a drive mechanism and a transmission mechanism. The crimping machine curls the two sides of the coiled material upwards and downwards respectively. Then, guided by an annular steel belt, the downward-curved side of the coiled material interlocks with the upward-curved side. Finally, the interlocking edges are pressed tightly by the crimping wheels that roll relative to each other.

[0003] In the prior art, a spiral duct air conditioner with a protective structure, as disclosed in publication number "CN218134051 U", has the air conditioner body mounted on top of a support plate, a battery mounted on top of a motor, a heating plate mounted on the side of the battery, and heat-absorbing cotton mounted on top of a base plate. This spiral duct air conditioner with a protective structure facilitates movement by installing a transmission structure on top of the base plate, and a dehumidification structure on top of the motor to prevent unnecessary damage caused by internal moisture growth. The protective structure on top of the base plate protects the entire machine. However, during use, the protective structure involves pushing the spiral duct air conditioner up and down to detach it from the cover. Combined with the increased size and weight of the spiral duct air conditioner, this increases the load on the bottom lifting structure. Furthermore, the heavy weight of the spiral duct air conditioner results in slow lifting, reducing its working efficiency and shortening its service life. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a spiral duct air conditioner, comprising: a base 1, which supports the entire device; a support plate 9 is fixedly connected to the upper surface of the base 1, facilitating the fixed installation of the spiral duct air conditioner via the support plate 9; the operation and use of the spiral duct air conditioner is existing technology and will not be elaborated further, with the model selected according to usage requirements; a protective cover 2 is attached to the upper surface of the support plate 9, which protects the spiral duct air conditioner; adjustment mechanisms 3 are provided on both sides of the protective cover 2, facilitating control of the protection. The lifting and lowering of the cover 2 is achieved by a detachable moisture-proof plate 4 installed on the top of the cover 2. The moisture-proof plate 4 can absorb moisture in the air to prevent moisture from affecting the spiral duct machine. The adjusting mechanism 3 includes a connecting block 5. One side of the connecting block 5 is fixedly connected to the side wall of the cover 2, and the other side of the connecting block 5 is fixedly connected to one side of the rack 6. A gear 7 is meshed on the other side of the rack 6. The gear 7 is fixedly sleeved on the end of the drive shaft 8. Driven by the drive shaft 8, the gear 7 is driven to rotate. The rack 6 is slidably sleeved in the support plate 9, and the support plate 9 limits the rack 6.

[0024] The spiral duct machine is fixedly installed on the upper surface of the support plate 9, and the entire device is stably supported by the base 1. When using the spiral duct machine, the drive shaft 8 is rotated by controlling the drive shaft 8 to drive the gears 7 fixedly sleeved at both ends of the drive shaft 8 to rotate. The gears 7 then mesh with the rack 6, and the rack 6 moves longitudinally under the limit of the support plate 9. Thus, under the connecting action of the connecting block 5, the protective cover 2 moves upward. The protective cover 2 gradually detaches from the spiral duct machine installed on the support plate 9 until the spiral duct machine is completely exposed. Then the spiral duct machine can be operated. The protective cover 2 plays a role in shielding and protecting the spiral duct machine. After the spiral duct machine is used, the drive shaft 8 is rotated in the reverse direction.

[0025] Example 2: Based on Example 1, the moisture-proof board 4 has insertion holes 10 on both ends. The insertion holes 10 are adapted to the insertion rods 11. The insertion holes 10 and one end of the insertion rods 11 are slidably connected. The other end of the insertion rods 11 is fixedly connected to one end of the spring 24. The other end of the spring 24 is fixedly connected to the inner wall of the limiting hole 12 opened inside the top side of the protective cover 2. The limiting hole 12 and the insertion rods 11 are slidably connected. The upper surface of the protective cover 2 has arc-shaped holes 13 on both sides, and the arc-shaped holes 13 are connected to the limiting holes 12. A sliding rod 14 is slidably connected in the arc-shaped holes 13. One end of the sliding rod 14 is fixedly connected to the outer ring surface of the insertion rods 11, and the other end of the sliding rod 14 is fixedly connected to the pull plate 15.

[0026] When the moisture-proof board 4 needs to be replaced, pull the two pull plates 15 in opposite directions to make the pull plates 15 drive the slide rod 14 to slide under the limit of the arc hole 13. At the same time, the slide rod 14 drives the insertion rod 11 to move away from the insertion hole 10. Simultaneously, the insertion rod 11 moves into the limiting hole 12 until the insertion rod 11 slides out of the insertion hole 10 completely. During this process, the spring 24 is compressed. Then, insert the new moisture-proof board 4 into the top of the protective cover 2, and then release the pull plates 15. Under the reverse elastic force of the spring 24, the spring 24 pushes the insertion rod 11 to move into the insertion hole 10, thereby limiting the newly installed moisture-proof board 4 again.

[0027] Example 3: Based on Example 2, through holes 16 are provided around the upper surface of the support plate 9. The through holes 16 limit the rack 6. A limiting block 17 is fixedly connected to one side of the through hole 16. The limiting block 17 is slidably connected to a sliding groove 18 on one side of the rack 6. Through the cooperation of the limiting block 17 and the sliding groove 18, the stability of the rack 6 in raising and lowering is initially improved. A T-shaped strip 19 is provided on one side of the limiting block 17. One side of the T-shaped strip 19 is welded and fixed to the inner wall of the through hole 16. The other side of the T-shaped strip 19 is connected to the limiting groove 20 on the rack 6. The sliding connection, through the sliding engagement of the T-shaped strip 19 and the limiting groove 20, further improves the stability of the rack 6 movement. The drive shaft 8 is fixedly sleeved with a worm wheel 21 in the middle, and a worm 22 meshes with the lower side of the worm wheel 21. A handwheel 23 is fixedly connected to one end of the worm 22. The two sides of the worm 22 are rotatably sleeved in the small support seat. A large support seat is set on one side of the small support seat. The drive shaft 8 is rotatably sleeved in the large support seat. The small support seat and the large support seat are both fixedly installed on the upper surface of the support plate 9, thereby ensuring the stability of the support for the worm 22 and the drive shaft 8.

[0028] When the spiral duct machine needs to be operated, the handwheel 23 is turned to drive the worm gear 22 to rotate. The worm gear 22 meshes with the worm wheel 21, which in turn drives the drive shaft 8 to rotate. The drive shaft 8 rotates under the limit of the large support seat, thereby driving the gears 7 fixed at both ends to rotate. The gears 7 then mesh with the rack 6, causing the rack 6 to slide. The rack 6 moves under the sliding engagement of the limit block 17 and the slide groove 18 and the sliding engagement of the limit groove 20 and the T-shaped strip 19. Then, the rack 6 drives the protective cover 2 to move synchronously through the connection of the connecting block 5. The protective cover 2 gradually detaches from the spiral duct machine installed on the support plate 9 until the spiral duct machine is completely exposed. Then the spiral duct machine can be operated. The protective cover 2 provides protection for the spiral duct machine. After the spiral duct machine is used, the handwheel 23 is turned in the opposite direction. The self-locking property of the worm wheel 21 and the worm gear 22 prevents the protective cover 2 from falling accidentally, thus improving safety.

[0029] In actual use, the device is stably supported by the base 1, and the support plate 9 is fixed on the base 1 for mounting the spiral duct air conditioner and the protective cover 2. The protective cover 2 achieves its lifting function through the adjustment mechanism 3 (including connecting block 5, rack 6, gear 7, and drive shaft 8). When the drive shaft 8 rotates, it drives the gear 7, which meshes with the rack 6. The rack 6 slides within the through hole 16 of the support plate 9. At the same time, the limiting block 17 and the slide groove 18, and the T-shaped strip 19 and the limiting groove 20 cooperate to improve the stability of the rack 6's movement. Finally, the connecting block 5 drives the protective cover 2 to move upward, allowing the spiral duct air conditioner to be fully exposed for operation. The moisture-proof plate 4 is installed on the top of the protective cover 2, and the insert rods 11 at both ends are connected to the limiting holes 12 inside the protective cover 2 through springs 24 for easy replacement. After operation, the drive shaft 8 is rotated in the reverse direction, and the protective cover 2 descends stably under the self-locking action of the worm gear 21 and worm 22 to prevent accidental falls and improve safety.
