[0023] The ratchet device comprises a ratchet shaft 1, a pawl guide elastic push piece 2, a guide pin 3, an inner half-rotating shell 4, a small rotating shaft 5, a pawl reset pin 6, a pawl 7, an outer half-rotating shell 8, a pawl return spring 9, a ratchet disc 15 and a ratchet wheel; one end of the ratchet shaft 1 is fixedly connected to the water tank radiator, and the other end of the ratchet shaft 1 is connected to the ratchet disc 15 through a key; a plurality of stroke grooves are formed in the end face of the ratchet disc 15, and the pawl guide elastic push piece 2 is arranged in each stroke groove; the middle part of the pawl guide elastic push piece 2 is fixed in the stroke groove of the ratchet disc 15, and the two ends of the pawl guide elastic push piece 2 can be freely bent.

[0024] The inner half-rotating shell 4 and the outer half-rotating shell 8 are buckled together and connected through bolts; the central holes of the inner half-rotating shell 4 and the outer half-rotating shell 8 are sleeved on the ratchet shaft 1, and the inner half-rotating shell 4 and the outer half-rotating shell 8 can freely rotate on the ratchet shaft 1; the ratchet wheel is installed between the inner half-rotating shell 4 and the outer half-rotating shell 8, and the ratchet wheel is connected to the ratchet shaft 1 through a key; a spring groove is formed in the outer end face of the outer half-rotating shell 8, a through hole A is formed in the bottom face of the spring groove, and the pawl return spring 9 is arranged in the spring groove;

[0025] The pawl 7 is mounted on the inner wall of the inner semi-rotating housing 4 via a small rotating shaft 5, and the pawl 7 is located outside the ratchet. The tail end of the pawl 7 is provided with a pawl reset pin 6.

[0026] like Figure 5 As shown, during the upward rotation of the first bracket, the guide pin 3 rotates synchronously with the first bracket 12. During rotation, the ratchet and ratchet shaft 1 remain stationary, while the guide pin 3 rotates clockwise around the ratchet shaft 1. During rotation, the guide pin 3 is positioned below the pawl guide elastic tab 2. Under the action of the pawl return spring 9, the front end of the pawl 7 remains in contact with the ratchet, thus achieving multi-angle stopping of the first bracket 12, facilitating the user to clear debris blocking the ventilation channel. After cleaning, the first bracket 12 is lifted again, causing the guide pin 3 to continue rotating clockwise. When the guide pin 3 rotates to... Figure 6 When the position is shown, the operator stops rotating the first support 12 and gradually lowers the first support 12. At this time, under the action of the pawl guide elastic lever 2, the guide pin 3 moves outside the pawl guide elastic lever 2, and the guide pin 3 drives the top of the pawl 7 to disengage from the ratchet, so that the lowering action of the first support 12 is completed smoothly under the action of gravity. When the first support is rotated to return to the initial working position, the guide pin 3 also returns to the initial position, completing one working cycle.

[0028] During the lifting process, the guide pin 3 rotates synchronously with the first bracket 12. During rotation, the ratchet and ratchet shaft 1 remain stationary, while the guide pin 3 rotates clockwise around the ratchet shaft 1. During rotation, the guide pin 3 is positioned below the pawl guide elastic tab 2. Under the action of the pawl return spring 9, the front end of the pawl 7 remains in contact with the ratchet, thus achieving multi-angle stopping of the first bracket 12, facilitating the user to clear debris blocking the ventilation channel. After cleaning, the first bracket 12 is lifted again, causing the guide pin 3 to continue rotating clockwise. When the guide pin 3 rotates to... Figure 6When the first support 12 is rotated to the position shown in the figure, the operator stops rotating the first support 12 and gradually lowers the first support 12; at this time, under the action of the pawl guide elastic tab 2, the guide pin 3 moves outside the pawl guide elastic tab 2, and the guide pin 3 drives the top of the pawl 7 to disengage from the ratchet, so that the first support 12 falls under the action of gravity; when the first support is rotated back to the initial working position, the guide pin 3 also returns to the initial position, and the cleaning work is completed; at this time, daily work can be carried out, and after a certain period of use, the above actions are repeated, and the water tank radiator can be cleaned again.

[0029] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
