The outer end of the eccentric wheel is fixedly connected with the lower ends of the rocking bars 3-12, and the eccentric wheel can rotate along with the swinging of the rocking bars. The springs 3-13 and the steel wires 3-7 are respectively fixedly connected with the upper end of the rocker from opposite directions, the springs are tension springs, and the other ends of the springs are fixedly connected with the partition plate, so that the rocker is in a strong tensioning state. The rocker, the spring and the steel wire are positioned between the box cover and the clapboard. The rocker drives the eccentric wheel to enable the rope to be in a self-locking state (the eccentric wheel is driven to rotate when the rope is pulled downwards, and the rope and the inner wall of the rope winder box are pressed more and more tightly due to the eccentric action), and at the moment, the rope can bear downward tension to drive the bicycle to realize lifting action. The other end of the steel wire is fixedly connected with the operating handle, the handle can be tightly held to overcome the spring force to pull the rocker to swing reversely, the rocker drives the eccentric wheel to enable the rope to be in a free state (self-locking is opened), at the moment, the rope can be pulled downwards only by overcoming the spring force, and the free adjustment of the grabbing height of the grabbing hook (front or back) is realized conveniently. The rope winding wheel overcomes the self weight of the (front or rear) grapple by the action of the coil spring force, always ensures the upward contraction state of the (front or rear) grapple, and can realize the vertical height adjustment action of the (front or rear) grapple by only small operating force.
When the bicycle needs to be clamped, the eccentric wheel is opened in a self-locking mode as long as the operating handle is held tightly, the rope can stretch freely, and at the moment, the grabbing position of the grabbing hook (front or back) can be freely adjusted to finish clamping and fixing actions. When the operating handle is released, the eccentric wheel can be self-locked, and the rope can pull the (front or rear) grapple to ensure that the bicycle is upright and cannot fall down, and can perform lifting action at the same time.
When the clamped bicycle needs to be removed, the operating handle is only held tightly, the eccentric wheel is opened in a self-locking mode, the rope can freely stretch and retract, the (front or rear) grapple is separated from the bicycle, the operating handle is released after the rope is placed at a proper position, the eccentric wheel can be self-locked, and the rope can pull the (front or rear) grapple.
The operating steps of the (front or rear) grapple are as follows:
the operating handle is held tightly to drive the steel wire rope to move, the steel wire rope swings with the rocker on the partition plate, the spring arranged on the side of the rocker is stretched, the rocker drives the eccentric wheel in the rope winding box to rotate through tooth-shaped matching, the eccentric wheel is self-locked and opened, and the coil spring can drive the rope winding wheel to always wind the rope upwards. At the moment, the grapple is pulled downwards with little force, and the rope can be stretched out along with the downward movement of the grapple. If the grapple moves upwards at this moment, the coil spring can drive the rope wheel to rotate and roll the rope, when the grapple reaches a proper position, the operating handle is loosened, the spring contracts to drive the rocker to reset, the rocker drives the eccentric wheel to reset through the tooth-shaped fit, so that the eccentric wheel tightly extrudes the rope in the wall of the rope coiling box, and when the rope moves downwards, the eccentric wheel can be driven to rotate through friction force, so that the extrusion force of the eccentric wheel on the rope is further increased, the rope is kept in a static state more firmly, an eccentric self-locking function is realized, the grapple is tensioned by the rope to keep the air position unchanged, and the grapple can lift along with the lower base plate, and the lifting function of the bicycle is.
