It is a device with self-clutching function that utilizes the speed change or rotation direction change of the driving and driven parts. One-way clutches are used in various mechanical equipment, including but not limited to automobiles, motorcycles, construction machinery, industrial production lines, etc. In automobiles, one-way clutches are often used in starting systems, transmission systems and differentials to achieve specific functions.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a combined planetary reduction check valve, including a gear sleeve 1, which is provided with a reduction planetary gear inside. It is an existing structure and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A connecting rod 2 is provided on the right side of the gear sleeve 1, which is used to connect the sleeve rod 3 to drive the sleeve rod 3 to rotate. The sleeve rod 3 is fixedly installed on the right outer wall of the connecting rod 2. The outer wall of the sleeve rod 3 is provided with a check valve body 4. A ratchet, a ratchet gear and a repulsive member are arranged inside the check valve body 4. A heat sink 2 6 is fixedly connected to the right outer wall of the check valve body 4. The heat sink 2 6 is provided with multiple groups to form a spiral shape, which helps to guide the flow of airflow, enhance the heat dissipation effect, and reduce the impact on the working state of the device. A heat dissipation component is provided on the outer wall of the sleeve rod 3. The heat dissipation component includes a mounting tube 51. The inner wall of the mounting tube 51 slides on the outer wall of the sleeve rod 3 for installing other heat dissipation components. A ventilation plate 52 is fixedly connected to the right side of the mounting tube 51. The ventilation plate 52 is provided with a through hole to allow air circulation.

[0033] Reference Figure 2 and Figure 3 A baffle 53 is fixedly connected to the left side of the ventilation plate 52. The baffle 53 is annularly arranged to surround the one-way device body 4, and is used to concentrate and guide the air flow, improve the heat dissipation effect, and reduce the impact on the working state of the device. A heat sink 54 is fixedly connected to the outside of the one-way device body 4, and is used to dissipate the heat generated by the one-way device body 4 to the surrounding environment. The top of the heat sink 54 slides on the left inner wall of the baffle 53. The left inner wall of the mounting tube 51 is rotatably connected with a fan blade 55, which is used to drive the air flow, thereby improving the heat dissipation efficiency. The right side of the fan blade 55 is fixedly connected with a toothed Ring 56, the top of the ring gear 56 is meshed with a main gear 57, the ring gear 56 and the main gear 57 are used in conjunction with each other, and the rotation of the main gear 57 drives the ring gear 56 to rotate, thereby driving the fan blades 55 to rotate. A driving motor 58 is arranged on the right side of the main gear 57, which is the main power source of the heat dissipation enhancement structure. The left side of the output shaft of the driving motor 58 is fixedly connected to the right side of the ring gear 56. When the driving motor 58 is started, it will drive the main gear 57 to rotate, and then drive the fan blades 55 to rotate. The bottom end of the driving motor 58 is fixedly connected to the top of the mounting tube 51 to ensure the stability of the structure.

[0034] Reference Figure 2 , Figure 4 and Figure 5When the locking cam 77 is in the unlocking state, the locking cam 78 is locked and the locking cam 73 is locked, so that the locking cam 78 can be locked in the unlocking state.

[0035] Working principle: When in use, first start the drive motor 58, and drive the main gear 57 to rotate through the output shaft of the drive motor 58. The bottom end of the main gear 57 meshes with the ring gear 56 to drive the ring gear 56 to rotate. When the ring gear 56 rotates, it drives the fan blades 55 to rotate on the left inner wall of the mounting tube 51. The fan blades 55 drive the air to flow by rotating to form wind force, and quickly dissipate the heat generated by the heat sink 2 6, the heat sink 1 54 and the one-way device body 4 to the surrounding environment, thereby improving the heat dissipation performance of the device, thereby maintaining the temperature of the one-way device body 4 during operation, ensuring its continuous, stable and efficient working state.

[0036] When it is necessary to install the heat dissipation component, the worker can manually pull up the pull rod 71 through the pull ring, slide the installation tube 51 on the outer wall of the sleeve rod 3, release the pull rod 71, and the compression spring 72 will push the pull rod 71 to reset, so that the bottom end of the pull rod 71 slides into the limiting hole 73, thereby fixing the installation tube 51 and the sleeve rod 3. When the heat dissipation component needs to be disassembled, just repeat the above steps, pull up the pull rod 71 again to disengage the bottom end of the pull rod 71 from the limiting hole 73, and then slide the sleeve rod 3 to slide the installation tube 51.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
