Example

1 to 2, the winch winding trigger assembly system of this embodiment includes a pulley 1 and a trigger launching system arranged on the rear side of the pulley 1. among them:

The trigger launching system includes a housing 3 and a winding ratchet mechanism, a trigger mechanism and a safety slider 4 assembled in the inner cavity of the housing 3. The winding ratchet mechanism is arranged on the rear side of the inner cavity of the housing 3 and includes a winding wheel, a ratchet wheel 8 fixedly assembled with the winding wheel, a pawl 9, a drive pawl 9 to lock the ratchet wheel 8 and a pawl spring 10 and The pawl 9 is driven to unlock the trigger lock rod 11 of the ratchet wheel 8. The trigger lock rod 11 and the pawl 9 are an integral structure, and the end thereof extends to the outside of the housing 3. The trigger mechanism is arranged on the front side of the inner cavity of the housing 3, and includes a lock hook 5, a trigger 6 matched with the lock hook 5, and a lock hook spring 12 arranged on the rear side of the lock hook 5 to drive the lock hook 5 to reset. The lock hook 5 is assembled on the housing 3 through a pin shaft and can rotate along the pin shaft. The trigger 6 is arranged below the lock hook 5, and its bottom end extends to the outside of the housing 3. The safety slider 4 is arranged between the winding ratchet mechanism and the lock hook 5 and can slide back and forth along the inner cavity of the housing 3 to drive the trigger lock rod 11 to move, thereby driving the pawl 9 to unlock the ratchet wheel 8. A pulley traction line 13 is provided between the pulley 1 and the reel.

In order to facilitate the resetting of the pulley 1 after launching, a pulley resetting device that pulls the pulley 1 to reset is also provided. The pulley resetting device is a tension coil spring 14, and the end of the tension coil spring 14 is connected to the pulley 1. The bottom of the fixed connection.

A string stop block 16 made of a soft material is provided on the rear side of the pulley 1, and the string stop block 16 is provided with a gap for hooking the string 2. When launching, the string stopper 16 functions as a string stopper, which effectively integrates the string stopper on the traditional crossbow, making the structure of the crossbow simpler and reducing the production cost.

The outer side of the housing 3 is provided with a rocking handle for driving the winding wheel to rotate and wind the winding.

In order to ensure that the winding process and launch process of the pulley 1 remain stable, referring to FIG. 3, the winding ratchet mechanism in this embodiment includes two winding wheels, a first winding wheel 7 and a second winding wheel 17, respectively. The first reel 7 and the second reel 17 are symmetrically arranged on both sides of the ratchet wheel 8. The bottom of the pulley 1 is equipped with two pulley guide wheels, the first pulley guide wheel 15 and the second pulley guide wheel 18 respectively. The front end of the housing 3 is provided with a threading groove 19, the threading groove 19 is horizontally arranged, and the cross-section of the threading groove 19 is arc-shaped when viewed from above. One end of the pulley traction wire 13 is wound on the first reel 7, and the other end is wound around the first pulley guide wheel 15, passing through the threading groove 19, and bypassing the second pulley guide wheel 18 in turn on the second reel 17 on.

The present invention is assembled on the crossbow arm as a crossbow, wherein the trigger launching system is fixedly assembled at the end of the crossbow arm, which can effectively avoid the problem of the return accuracy of the mobile trigger launching system due to movement. The tension coil spring 14 is assembled on the front end of the crossbow arm through a pin shaft. When the tension coil spring 14 is wound, the tension coil spring 14 is stretched and deformed. After firing, the pulley 1 is reset under the action of the restoring force of the tension coil spring 14.

The working principle of the present invention is briefly described as follows:

Rotating the crank handle drives the rotation of the first reel 7, the second reel 17 and the ratchet 8, and the pulley traction wire 13 is continuously wound on the first reel 7 and the second reel 17, and then drags the pulley 1 direction Move the trigger firing system in the direction, and drag the string 2 and the tension spring 14 at the same time until the string 2 touches the lock hook 5, and the lock hook 5 rotates the hanging string (refer to Figure 2 for the state of the lock hook 5 after hanging the string). At this time, due to the backward force of the string 2, the safety slider 4 is pushed to move backward to drive the trigger lock lever 11 to move, and the pawl 9 is driven to unlock the ratchet wheel 8, so that the ratchet wheel 8 is unlocked while the string is in place. Pull the trigger 6 to drive the lock hook 5 to unlock the string 2 to complete the launch. At the same time, the pulley 1 quickly moves forward under the action of the tension coil spring 14 and returns to the original position to wait for the next winding.

The pawl 9 can lock the ratchet wheel 8 at any time under the action of the pawl spring 10. Therefore, the pulley 1 can be stopped at any position at any time during the winding process. If you want to withdraw from the winding, you can press the trigger lock lever 11 to the unlocked position (the trigger lock lever 11 is in the unlocked state, refer to Figure 2) to release the pulley 1.

The invention combines the structures on the crossbow effectively, and uses the mutual linkage of the winding ratchet mechanism and the trigger mechanism to solve the problem of slow loading and poor winding of the crossbow, more convenient to use, and at the same time, to improve the control of the crossbow It improves the safety of use.
