[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] As shown in Figures 1-4, this utility model provides a quick-release and detachable rotating hub placement platform for water curtain machines. The quick-release and detachable rotating hub placement platform for water curtain machines includes a fixed shell 1, a sliding rod 2, a spring 3, a connecting kit 4, an inner support mechanism 5, an inner support plate 51, a first connecting rod 52, and a second connecting rod 53.

[0019] The fixed housing 1 is cylindrical, which is beneficial for its stability and uniform force distribution, and can also easily accommodate other mechanisms, such as the slide rod 2 and the spring 3. The top end of the slide rod 2 is fitted onto the bottom end of the fixed housing 1. The slide rod 2 connects the fixed housing 1 and the inner support mechanism 5, and its function is to drive the inner support mechanism 5 through up-and-down movement. The position of the inner support plate 51 is adjusted by sliding to ensure that the hub can be placed stably. The fixed housing 1 is equipped with a spring 3, one end of which is connected to the top end of the slide rod 2. The spring 3 acts as a restoring force, ensuring that the slide rod 2 can rebound after being pulled. Through the rebound of the spring 3, the slide rod 2 can drive the connecting kit 4 and the inner support mechanism 5 to return to their original positions, thereby locking and fixing the hub.

[0020] In this invention, the connecting kit 4 is fixedly sleeved onto the body of the slide rod 2. Through its connection with the slide rod 2, the connecting kit 4 ensures that the movement of the slide rod 2 can be directly transmitted to the inner support mechanism 5. It also acts as a stabilizer, ensuring that the inner support mechanism 5 can be adjusted smoothly and preventing irregular movement of the inner support plate 51.

[0021] In this invention, multiple sets of inner support mechanisms 5 are arranged around the connecting kit 4. Each set of inner support mechanisms 5 includes an inner support plate 51, a first connecting rod 52, and a second connecting rod 53. The bottom end of the first connecting rod 52 is hinged to the connecting kit 4, and the top end of the first connecting rod 52 is hinged to the inner support plate 51. One end of the second connecting rod 53 is hinged to the inner support plate 51, and the other end of the second connecting rod 53 is hinged to the outer side of the fixed shell 1. There are three sets of inner support mechanisms 5, evenly distributed around the slide rod 2. The surface of the inner support plate 51 is provided with anti-slip texture to increase the friction with the center hole of the wheel hub. The design of multiple inner support plates 51 and connecting rods can evenly support the center hole of the wheel hub. Through the linkage of the inner support plates 51 and connecting rods, the angle and position of the inner support plates 51 can be precisely adjusted when the slide rod 2 is pulled down, thereby fixing the wheel hub and ensuring its stability.

[0022] In this invention, the bottom end of the rotating shaft 6 is fixedly sleeved with the top end of the fixed shell 1, and the other end of the spring 3 is connected to the bottom surface of the rotating shaft 6. The rotating shaft 6 connects the fixed shell 1 and the housing 7, and rotates through a bearing. This design allows the hub to rotate after installation, facilitating painting or other treatments and ensuring the hub's flexibility. Since the fixed shell 1 is mounted on the shaft of the rotating shaft 6, and the rotating shaft 6 is connected to the housing 7 through a bearing, painting the hub after installation only requires turning the hub to rotate it, ensuring flexibility.

[0023] In this invention, the housing 7 is fitted with the top end of the rotating shaft 6. One end of the telescopic rod 8 is fixedly connected to one side of the housing 7. The telescopic rod 8 and the transmission rod 9 are fixedly sleeved together. The rotating shaft 6 is connected to the housing 7 via a bearing. The housing 7 surrounds the rotating shaft 6 and provides a fixed position for the telescopic rod 8. The design of the telescopic rod 8 allows the device to be adjusted at different operating angles and rotated via the bearing, enabling the hub to be rotated to the required spraying angle. The other end of the telescopic rod 8 is sleeved on the body of the transmission rod 9. The locking frame 10 is located on the side wheel surface of the telescopic rod 8. One end of the transmission rod 9 passes through the locking frame 10, and the transmission rod 9 and the locking frame 10 are rotatably connected. The transmission rod 9 drives the telescopic rod 8 and the rotating shaft 6 to rotate through the locking frame 10, thereby completing the hub rotation operation. The telescopic function of the telescopic rod 8 can be extended when supporting a hub with a larger diameter to accommodate its outer diameter.

[0024] The rotating design of the latching frame 10 ensures that the transmission rod 9 can switch between latching and releasing. The top of the support frame 14 is fixedly connected to the bottom surface of the latching frame 10 to support the latching frame 10. The ratchet 11 is sleeved on the rod body of the transmission rod 9 and is located inside the latching frame 10. The latching frame 10 is U-shaped, and the ratchet 11 is fixedly sleeved on the rod body of the transmission rod 9. The bottom end of the extension shell 12 is fixedly connected to one side of the latching frame 10. The latching lever 13 includes a hinge end 131, a torsion spring 132, a pressing end 133, and a latching end 134. The hinge end 131 is hinged to the top of the extension shell, and the torsion spring 132 is sleeved on the hinge end 131. One end of the torsion spring 132 is connected to the pressing end 133, and the other end of the torsion spring 132 is connected to the hinge shaft of the extension shell. The latching end 134 is connected to the ratchet 11. Engagement. The design of the ratchet 11 and the latching lever 13 provides a locking mechanism. When the latching lever 13 rotates and engages with the ratchet 11, it holds the hub at the desired angle. The reset function of the latching lever 13 ensures that the hub is fixed and stable after being flipped; the torsion spring 132 works in conjunction with the latching lever 13 to provide a restoring force, allowing the latching lever 13 to reset after operation, thus achieving the locking function.

[0025] It should be noted that the detachable and removable rotating hub placement platform for the water curtain machine designed in this utility model is used by placing the utility model inside the water curtain machine and pulling down the sliding rod 2. After receiving the pulling force, the sliding rod 2 pulls the spring 3 at the top, generating a rebound force. The connecting kit 4 of the sliding rod 2 will also move down together, and the multiple sets of inner support mechanisms 5 hinged to the connecting kit 4 will be pulled together. Taking one set of inner support mechanisms 5 as an example, the bottom end of the first connecting rod 52 is driven down by the connecting kit 4, and the tilt angle between the first connecting rod 52 and the sliding rod 2 will gradually decrease. The top end of the first connecting rod 52 will drive the inner support plate 51 to gradually approach the sliding rod 2. The second connecting rod 53, which is hinged to the outside of the fixed shell 1 above the first connecting rod 52, will also be pulled and fitted together. The inner support plates 51 of each inner support mechanism 5 will be pulled together. When the inner support is fitted to the rod body, the inner support diameter will be reduced. At this time, the center hole of the wheel hub is fitted onto each inner support plate 51. The slide rod 2 is released, and the spring 3, which loses tension, rebounds in the fixed shell 1. The rebound of the spring 3 causes the slide rod 2 to move upward. The upward movement of the slide rod 2 causes the connecting kit 4 to move upward, pressing the bottom end of the first connecting rod 52, so that the angle between it and the body of the slide rod 2 increases. The inner support plate 51 will move away from the slide rod 2 and gradually support the inner diameter of the center hole of the wheel hub, thus fixing it.

[0026] When it is time to spray the bottom surface of the wheel hub, simply manually move the locking lever 13. The rotation of the locking lever 13 compresses one end of the torsion spring 132 below the moving end, and the torsion spring 132 generates a rebound force. After the locking lever 13 disengages from the meshing teeth of the ratchet 11, rotate the transmission rod 9. The transmission rod 9 drives one end of the telescopic rod 8 sleeved on its body. The rotating shaft 6, which runs longitudinally through the other end of the telescopic rod 8, will cause the wheel hub, supported by the inner support mechanism 5, to rotate together. After the telescopic rod 8 has rotated more than 90 degrees horizontally, the bottom surface of the wheel hub can be fully exposed to the sprayer for spraying. Finally, simply release the locking lever 13. The torsion spring 132, no longer compressed, drives the locking lever 13 to reset until the locking end 134 of the locking lever 13 engages with the meshing teeth of the ratchet 11. The ratchet 11... If it cannot rotate, the hub at that angle will be fixed.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
