In this scheme, the degree of depth of ball spout increases gradually from a left side to the right side, when the anticlockwise corotation of motor, the ball rolls to the left side in the ball spout, with first connection pad, the second connection pad supports, the second connection pad rotates along with first connection pad and drives by actuating device rotation, when the clockwise reversal of motor, the ball rolls to the right side in the ball spout, the big right side of ball roll ball spout degree of depth and second connection pad contactless, the second connection pad does not receive the force and does not rotate, thereby avoid being damaged by actuating device.
Preferably, the ball chutes are arranged at equal intervals along the circumferential direction along the inner wall of the through hole.
Preferably, the elastic member is a spring.
Preferably, the first connecting disc is provided with a connecting hole along the axial direction for connecting a rotating shaft of the motor.
Preferably, the outer wall of the second connecting disc is provided with a connecting groove for connecting a driven device.
The utility model has the beneficial effects that: when the motor rotates reversely, the driven equipment can be driven without the power of the motor, and the equipment is prevented from being damaged.
Drawings
FIG. 1 is a schematic structural view of an embodiment;
fig. 2 is an installation schematic of the embodiment.
In the figure: 1. the chain wheel comprises a first connecting disc, a second connecting disc, a through hole, a ball sliding groove, a ball, a spring, a connecting hole, a connecting groove, a motor, a chain wheel seat, a chain wheel and a chain wheel, wherein the first connecting disc is 2, the second connecting disc is 3, the through hole is 4, the ball sliding groove is 5, the ball is 6, the spring is 7, the connecting hole is 8, the connecting groove is 9, the motor is 10, the chain wheel seat is 11, and the chain wheel is arranged.
Detailed Description
The technical scheme of the utility model is further specifically described by the following embodiments and the accompanying drawings.
Example (b): the device for preventing the motor from reversing of the embodiment comprises a first connecting disc 1 used for connecting a rotating shaft of the motor and a second connecting disc 2 used for connecting driven equipment, wherein the second connecting disc 2 is provided with a through hole used for placing the first connecting disc 1 along the axial direction, the first connecting disc 1 is positioned in the through hole 3 and is not in contact with the second connecting disc 2, the first connecting disc 1 is coaxial with the second connecting disc 2, eight ball chutes 4 are arranged on the inner wall of the through hole 3 at equal intervals along the circumferential direction, balls 5 are arranged in the ball chutes 4, the balls 5 are connected with the right side wall of the ball chutes 4 through elastic components, the depth of the ball chutes 4 is gradually increased from left to right, the diameter of the balls 5 is larger than the leftmost depth of the ball chutes 4 and is smaller than the rightmost depth of the ball chutes 4, when the balls 5 are positioned on the left side of the ball chutes 4, two ends of the balls 5 are respectively connected with the first connecting disc 1, The second connecting discs 2 are abutted.
