Examples

Referring to FIGS. 1-2, the winch winding trigger assembly system described in this embodiment includes a trolley 1 and a trigger launching system provided on the rear side of the trolley 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 provided on the rear side of the inner cavity of the housing 3, and includes a winding wheel, a ratchet 8 fixedly assembled with the winding wheel, a pawl 9, a pawl spring 10 that drives the pawl 9 to lock the ratchet 8, and The driving pawl 9 unlocks the trigger lock lever 11 of the ratchet 8. The trigger lock lever 11 and the pawl 9 are an integral structure, and the end of the trigger lock lever 11 extends to the outside of the housing 3. The trigger mechanism is provided 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 provided 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 provided below the lock hook 5 and its bottom end extends to the outside of the housing 3. The safety slider 4 is disposed between the winding ratchet mechanism and the lock hook 5, and can slide the trigger lock lever 11 forward and backward along the inner cavity of the housing 3 to drive the pawl 9 to unlock the ratchet 8. A trolley traction wire 13 is provided between the trolley 1 and the reel.

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

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

The outer side of the housing 3 is provided with a swing handle that drives the winding wheel to rotate the winding.

In order to ensure that the winding process and the launching process of the pulley 1 remain stable, referring to FIG. 3, the winding ratchet mechanism in this embodiment includes two winding wheels, which are 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 8. The bottom of the pulley 1 is equipped with two pulley guide wheels, which are a first pulley guide wheel 15 and a second pulley guide wheel 18, respectively. The front end of the housing 3 is provided with a threading groove 19, and the threading groove 19 is horizontally arranged, and its cross-section in a plan view is curved. One end of the pulley traction wire 13 is wound on the first reel 7, and the other end is sequentially wound around the first pulley guide wheel 15, through the threading groove 19, and around the second pulley guide wheel 18 and wound on the second reel 17 on.

This creation is assembled as a crossbow machine on the crossbow arm, wherein the trigger launching system is fixedly mounted on the end of the crossbow arm, which can effectively avoid the problem of the recovery accuracy of the mobile trigger launching system due to movement. The extension coil spring 14 is assembled on the front end of the crossbow arm through a pin shaft. When winding, the extension coil spring 14 is stretched and deformed, and after launching, the carriage 1 is reset under the action of the restoring force of the extension coil spring 14.

The working principle of this creation is briefly described as follows:

Rotating the rocker handle drives the first reel 7, the second reel 17 and the ratchet 8 to rotate, 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 launching system in the direction, and drag the string 2 and the extension coil 14 at the same time until the string 2 contacts the lock hook 5 and the lock hook 5 rotates to hang the string (refer to FIG. 2 for the state of the lock hook 5 after the string is hung). At this time, due to the backward force of the string 2, the safety slider 4 is pushed backward to drive the trigger lock lever 11 to move and then the pawl 9 is driven to unlock the ratchet 8, so that the ratchet 8 is unlocked while the string is in place. Pull the trigger 6 and drive the hook 5 to unlock the string 2 to complete the launch. At the same time, the pulley 1 moves forward quickly under the action of the tensile 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 exit the winding, you can press the trigger lock lever 11 to the unlock position (the trigger lock lever 11 is unlocked, see Figure 2) to release the trolley 1.

In this creation, the structure on the crossbow is effectively associated and combined. The mutual interaction of the winding ratchet mechanism and the trigger mechanism solves the problem of slow filling and poor winding of the crossbow. It is more convenient to use and improves the control of the crossbow. And improve the safety of use.
