Detailed Description

The structure of the clutch device of the utility model is shown in fig. 1-4, which comprises a shifting fork 28 and a combination body 29, wherein the shifting fork 28 comprises a semicircular shifting fork frame 34 matched with the excircle diameter of the combination body 29, the inner sides of the two ends of the shifting fork frame 34 are fixedly provided with a sliding block 33 through bolts 32, the lower end of the shifting fork frame 34 is connected with a handle rod 35, and the upper end of the handle rod 35 is provided with a handle 31; the outer circumference of the combination body 29 is provided with a circle of sliding grooves 36 matched with the sliding blocks 33, and the position and the direction of the handle 31 can be adjusted through the sliding between the sliding blocks 33 and the sliding grooves 36. A central hole matched with the excircle of the shaft 14 is formed in the center of the combined body 29, a key groove 39 matched with a key 37 on the shaft 14 is formed in the central hole, and the combined body 29 and the shaft 14 are slidably mounted through the key 37 and the key groove 39; the first chain wheel 16 is movably arranged on the shaft 14 through a fixed sleeve 15, a clutch key 30 is arranged on the combined body 29 at one side of the first chain wheel 16, a clutch hole 38 matched with the clutch key 30 is arranged on the first chain wheel 16, and the combined body 29 and the first chain wheel 16 are arranged through the clutch key 30 and the clutch hole 38 in a matched mode.

The working principle is as follows: the clutch device is arranged on a shaft 14, a chain wheel or a belt pulley used for driving an execution component (a motor) is arranged on the shaft 14, the chain wheel or the belt pulley on the shaft 14 is connected with the execution component through a chain or a belt to realize power transmission, and the clutch device matched with the chain wheel or the belt pulley is arranged on the shaft 14 to realize the on-off of the power transmission. The shaft 14 is connected directly to the actuator or to the shaft of the actuator via another sprocket or pulley mounted thereon, so that the power of the actuator is transmitted to the actuator when the clutch is engaged with the previous sprocket or pulley.

In this embodiment, when the clutch device is in the disengaged state, the clutch key 30 on the combination body 29 of the clutch device is disengaged from the clutch hole 38 on the first sprocket 16 on the shaft, and when the driving motor is started, because the driving motor and the first sprocket 16 are driven by the chain, the first sprocket 16 slides and rotates on the shaft 14 under the driving of the driving chain, and the shaft 14 does not rotate. When the motor is normally operated, the handle 31 drives the handle rod 35 to push the fork arm 34 towards the first chain wheel 16, the slide block 33 of the fork arm 34 is clamped in the slide groove 36, so that the fork arm 34 and the combined body 29 form an integral structure, the key groove 39 of the combined body 29 slides on the key 27 of the shaft 14, the combined body 29 is pushed towards the first chain wheel 16, one circle of clutch keys 30 of the combined body 29 is inserted into one circle of clutch holes 38, the combined body 29 and the first chain wheel 16 are fixed, and the shaft 14 rotates under the rotation of the first chain wheel 16, and further the actuating component is driven to rotate by the second chain wheel 18 and the chain, as shown in fig. 5. Conversely, when the handle 31 is pushed in a direction away from the first sprocket 16, the clutch device and the first sprocket are disengaged, the shaft 14 is driven to rotate when the clutch device is coupled with the first sprocket 16 of the shaft 14, and when the clutch device is disengaged from the first sprocket 16 of the shaft 14, the first sprocket 16 slides on the shaft 14 and does not rotate the shaft 14, as shown in fig. 6. When the driving component (motor) just starts, the clutch device is in a separation state, and after the driving component normally runs, the clutch device is pressed down, the execution component starts to work, so that the motor is started to form buffering, and the motor is not easy to burn out.
