Referring to FIGS. 1 and 7 , the rope guide 50 can be changed from a use position located in front of the bracket 20 to a folded position located at the top of the bracket 20 .

When the rope guide 50 is in the use position, the steel rope 10 can be passed through the front and rear guide holes 56 and enter between the top drum 31 and the bottom drum 32. The rope device gives the steel rope 10 a retracting force, so that the steel rope 10 continues to move backward.

Referring to Figures 1, 6 to 9, when the rewinding operation of the steel rope 10 is completed and the rope guide 50 is to be moved to the retracted position, first, the gripping block 64 is positioned in the rear positioning groove 623. , meaning that the locking unit 60 is in the unlocked state, and then the rope guide 50 is moved to the left end and located in front of the guard base 70 , and then a backward rotation force is applied to the connection unit 40 to make it The left swing arm 41 and the right swing arm 42 swing toward the rear, and use the guide rod 43 to drive the rope guide 50 to move to the top plate 21 of the bracket 20 and simultaneously enter the accommodation space 74 of the guard seat 70 At this time, the rope guide 50 rotates 90 degrees so that the locking rod 63 extends along the top-bottom direction Z, and the locking rod 63 is aligned with the locking hole 65. Finally, hold the gripping block 64 and By driving the locking rod 63 to move toward the top plate 21 , the locking rod 63 can pass through the through hole 711 and be inserted into the locking hole 65 , so that the locking unit 60 is in the locked state. When the gripping block 64 enters In the front positioning groove 622, the gripping block 64 is separated from the guide groove 621, and the locking rod 63 cannot move.

Referring to Figures 9, 8, 7, and 1, to move the rope guide 50 to the use position, first, pull the gripping block 64 out of the front positioning groove 622 and into the guide groove 621, and then Grasp the gripping block 64 and move it away from the top plate 21 to drive the locking rod 63 away from the locking hole 65 and the through hole 711 and put the locking unit 60 in the unlocked state. Then, Once the connecting unit 40 is rotated forward, the left swing arm 41 and the right swing arm 42 can swing forward, and the guide rod 43 drives the rope guide 50 to move to the position in front of the bracket 20 . position, and by the left stop 271 By blocking the left swing arm 41 and blocking the right swing arm 42 by the right block 281, the forward swing strokes of the left swing arm 41 and the right swing arm 42 can be restricted, allowing the rope guide 50 to reach the use position. Just stop moving.

Through the above description, the functions and advantages of the rope guide device of the winch of the present invention can be summarized as follows:

1. Through the connection unit 40 of the present invention, the rope guide 50 can be driven to change between the use position located in front of the bracket 20 and the retracted position located at the top of the bracket 20. When the rope guide 50 is located in the retracted position, Close the position to avoid being hit or damaged.

2. The present invention only needs to rotate the connecting unit 40 to drive the rope guide 50 to change between the use position and the folded position. There is no need to install or disassemble the rope guide 50, which is very convenient to use.

3. The present invention uses the locking unit 60 to lock the rope guide 50 in the folded position, thereby improving the stabilizing effect of the rope guide 50 in the folded position.

4. The present invention uses the protective seat 70 to not only protect the rope guide 50, but also prevent the rope guide 50 from excessive shaking, thereby reducing the chance of damage to the rope guide 50.

In summary, the rope guide device of the winch of the present invention can indeed achieve the purpose of the present invention.

However, the above are only embodiments of the present invention and should not be used as examples. Limiting the implementation scope of the present invention, any simple equivalent changes and modifications made based on the patent scope of the present invention and the contents of the patent specification are still within the scope of the patent of the present invention.
