DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The present invention will become clearer in light of the following detailed description of an illustrative embodiment of this invention described in connection with the drawings.

[0019] With reference to FIGS. 1 to 4 for a power winch 1 in accordance with an embodiment of the present invention, the power winch 1 is assembled in a horizontal assembly mode, and the power winch 1 has a power source 11 (such as a power motor, or an electric motor), and after the power source 11 outputs a power, and the outputted power is transmitted to and acted by a deceleration device 12, a rope wheel 13 is driven to perform a forward rotation or a reverse rotation to release or retract the rope when needed.

[0020] In the figures, both of the power source 11 and the rope wheel 13 have a long cylindrical appearance, so that the power source 11 and the rope wheel 13 can be assembled and configured to be parallel and adjacent to each other, and the common exterior of the output end of the power source 11 and the deceleration device 12 is covered by an outer casing 111, so that the output end of the power source 11 and the deceleration device 12 are hidden, and a set of first and second support frames 14, 15 is provided for jointly supporting the aforementioned structure, wherein the joint of the first support frame 14 for supporting the outer casing 111 and the rope wheel 13 is supported by the first support frame 14, so that the outer casing 111 and the rope wheel 13 are disposed on both sides of the first support frame 14 respectively, and the second support frame 15 is mounted onto the other side of the rope wheel 13. In other words, the rope wheel 13 is jointly supported by the set of first and second support frames 14, 15. The deceleration device 12 includes a clutch device for disconnecting the power transmission with the rope wheel 13 (when necessary) in order to release the rope quickly by manpower, and the clutch device includes a clutch handle 121 disposed on an outer sidewall of the second support frame 15.

[0021] In order to obtain symmetry of the assembly, the set of first and second support frames 14, 15 are manufactured in form of rectangular frames, and the set of first and second support frames 14, 15 has a plurality of corresponding engaging holes 141, 151 (such as screw holes) formed at symmetrical positions on the periphery of the set of first and second support frames 14, 15, and a set of cross plates 16 (such as two cross plates 16) are provided and a through hole 161 is formed separately at four ends of the set of cross plates 16 for the convenience and stability of the assembling, so that the cross plate 16 can be installed at different positions along the periphery of the set of support frames 14, 15. For example, one of the cross plates 16 is installed at the backside of the set of support frames 14, 15 and the other cross plate 16 is installed at the top side of the set of support frames 14, 15, and each through hole 161 formed separately at four ends of each cross plate 16 is aligned precisely with a respective engaging hole 141 or 151, and then an engaging member 17 (such as a bolt) is passed through the through hole 161 and locked with the engaging hole 141 or 151 securely, so as to couple and support the set of cross plates 16 and achieve a secured structural assembly.

[0022] In FIGS. 1 to 4, the power winch 1 is assembled into a horizontal assembly mode, so that its width w1 is greater than its height h1 (as shown in FIG. 1), and a rope outlet board 18 is installed in front of the power winch 1 and along the periphery of the set of support frames 14, 15, and the rope outlet board 18 comprises a horizontal rope management slot 181 formed thereon, and a through hole 182 formed separately at four corners of the rope outlet board 18, so that the rope outlet board 18 is disposed at the front of the set of support frames 14, 15, and each through hole 182 formed separately at four corners of the rope outlet board 18 is aligned precisely with a respective engaging hole 141 and 151, and then an engaging member 17 (such as a bolt) is passed through the through hole 182 and locked securely with the engaging hole 141 and 151, so that the horizontal rope management slot 181 of the rope outlet board 18 can be aligned precisely with the rope wheel 13 and becomes an important inlet/outlet slot of the rope wheel 13 for releasing and retracting the rope. In the meantime, the rope outlet board 18 can help making the assembly between the set of support frames 14, 15 more stable. Finally, an electric control box 19 is installed to (or mounted onto) the cross plate 16 at the top side (which is the second cross plate 16 described above), so that the display panel 191 on the electric control box 19 is facing forward to facilitate its viewing by the operator.

[0023] In the structure as disclosed above, the power source 11 and the rope wheel 13 can be installed a spatial range between the set of first and second support frames 14, 15, and then the output end of the power source 11 is passed out from the first support frame 14 and installed onto the deceleration device 12 and the outer casing 111, and then the set of cross plates 16 (such as two cross plates 12) are installed at the backside and the top side of the set of support frames 14, 15 respectively to achieve a secured locking effect, and a basic assembly is formed so far. The next step is to choose a horizontal assembly mode or an upright assembly mode.

[0024] With reference to FIGS. 1 to 4 for the horizontal assembly mode, the basic assembly is set to a mode that its width w1 is greater than its height h1 (as shown in FIG. 1), and then the rope outlet board 18 is mounted and locked onto the front cross plate 16 which has not been locked onto the set of support frames 14, 15 yet, and then the engaging member 17 is passed through the corresponding through hole 182 and locked with the corresponding engaging hole 141 and 151, and then the electric control box 19 is mounted onto the top cross plate 16, and the display panel 191 on the electric control box 19 is arranged to be facing forward, so as to complete the assembly in the horizontal assembly mode.

[0025] With reference to FIGS. 5 to 8 for the upright assembly mode, the basic assembly is rotated and set to a mode that its width w2 is smaller than its height h2 (as shown in FIG. 5), and then the rope outlet board 18 is mounted onto the front cross plate 16 which has not been locked onto the set of support frames 14, 15 yet, and then the engaging member 17 is passed through the corresponding through hole 182 and locked with the corresponding engaging hole 141 and 151, so that the horizontal rope management slot 181 of the rope outlet board 18 is aligned precisely with the rope wheel 13 and becomes an important inlet/outlet of the rope wheel 13 for releasing and retracting the rope, and then the electric control box 19 is mounted and locked onto the top cross plate 16, and the display panel 191 on the electric control box 19 is facing forward, so as to complete the assembly in the upright assembly mode.

[0026] From the description above, as long as the power winch 1 has the power source 11, the deceleration device 12, the outer casing 111, the rope wheel 13, the first and second support frames 14, 15 and the set of cross plates 16 (or two cross plates 16) are assembled to produce a basic assembly, the rope outlet board 18 and the electric control box 19 can be assembled with the basic assembly to produce an assembly in the horizontal assembly mode or the upright assembly mode, and the two assembly modes can be switched quickly, so that the power winch 1 has the effects of reducing the manufacturing cost, improving the convenience of assembling, and improving the scope of application.

[0027] In summation of the description above, the easily changeable assembly type power winch of the present invention is novel, and the invention can achieve the expected effects and comply with the patent application requirements, and thus is duly filed for patent application.
