Description

TECHNICAL FIELD

[0001] The utility model relates to a power winch clutch handle steering mechanism, especially a power winch clutch handle steering mechanism which can adjust the setting position of the clutch handle at any time according to requirements, so that the installation and use mode of the power winch is more wide and various.

BACKGROUND

[0002] A power winch is a power machine tool which is arranged to hang heavy objects or pull loads. For example, a "hoisting winch" used for vertical lifting of goods on a high-rise building is a power winch. For another example, a cable winch tool installed on a jeep or an off-road vehicle is also a power winch, which is used to tow another vehicle or move out of danger. Figure 1 As shown in the prior art, a power source 11 (for example, a power motor) is arranged on one side to output forward or reverse transmission power. A reduction device 12 is arranged on the other side. The power source 11 and the reduction device 12 are connected by a transmission shaft (not shown in the figure) to transmit power. The power source 11 and the reduction device 12 are connected and supported by a support frame 13. The inside space of the support frame 13 is provided with a cable wheel 14. The transmission shaft passes through the inside of the cable wheel 14. Therefore, the power provided by the power source 11 is transmitted to the reduction device 12 through the transmission shaft. After being appropriately reduced, the reduction device 12 drives the cable wheel 14 to rotate (forward or reverse) to release or retract a cable. The front end of the cable is hooked to a load (heavy object, another vehicle, or another object) by a hammer hook to move the load.

[0003] Since the power winch is arranged to release or retract the cable by using power, the speed of releasing or retracting the cable is inevitably not too fast due to the necessity of step-by-step reduction of the reduction device 12. Therefore, when used in an emergency situation (for example, rescuing a vehicle or a person in danger), the speed of releasing the cable by power often does not meet the expectation. Therefore, a clutch is arranged on the prior art power winch. The only thing that can be seen on the outside of the power winch is a clutch handle 15. The main components of the clutch are hidden inside the housing of the reduction device 12. When the clutch handle 15 is operated to make the clutch in the "disengaged" state, the power between the reduction device 12 and the cable wheel 14 is disconnected (OPEN). At this time, the cable wheel 14 is not affected by power, so that the cable on the cable wheel 14 can be directly and quickly pulled out by manpower, and the hooking to the vehicle to be rescued or the heavy object to be lifted is performed early. Then, when the clutch handle 15 is operated to make the clutch return to the "engaged" state, the power of the reduction device 12 is transmitted to the cable wheel 14 again (CLOSE), so that the cable and the heavy object are retracted by power.

[0004] The clutch of the power winch has various compositions and operation modes. The applicant has obtained the following patents: Taiwan New Patent Nos. 186419, 188404, M291421, M344336, M449152, M540860, M542645; Taiwan Utility Model Patent Nos. ZL01204721.X, ZL200520145068.5, ZL200820128343.6, 201220610649.1; and US Patent Nos. 7648125, 8973902, 10189686, 10138099.

[0005] Referring to Figure 1 As shown in the drawings, the power source 11, the reduction device 12 and the clutch handle 15 in the conventional power winch have a fixed impression. In particular, the clutch handle 15 is arranged above the housing of the reduction device 12, which is a fixed impression that cannot be changed. It is generally believed that the clutch handle 15 arranged above the housing of the reduction device 12 is the most easily contacted position and thus the best operation position. The conventional power winch is mostly installed (fastened) at the bottom of the front end of a vehicle, fixed above the front end of a chassis or fixed on a front bumper. Later, the user developed a use mode of installing (fastening) the power winch at the bottom of the rear end of a vehicle, fixed above the rear end of a chassis or fixed on a rear bumper. Even a use mode of installing the power winch on an additional frame above a vehicle body was developed. In these installation modes, the clutch handle is upward, so the user can easily operate it without any difficulty. Recently, the user of a vehicle popularly hides the wind and likes various devices arranged outside the vehicle body to be hidden as much as possible in normal times. Therefore, the user developed a use mode of installing (fastening) the power winch at a position below the front of a vehicle body or below the rear of a vehicle body. However, the clutch handle is downward in this case, which causes difficulty in operation in an emergency. In addition, the downward clutch handle is likely to collide with other objects when the vehicle is running at high speed. These are the fixed positions of the clutch handle (cannot be changed), which causes the lack of convenience in use.

[0006] In the conventional power winch, if the clutch handle 15 is intended to be turned, for example, the clutch handle 15 is intended to be turned from the original upward direction to the front direction, the outer housing of the reduction device 12 and the reduction mechanism and brake mechanism arranged inside the housing must be disassembled. Then, the round housing of the clutch handle 15 is turned together with the clutch handle 15 and reassembled. The disassembly and reassembly of the components and operations are very complicated. Therefore, the user cannot handle it by himself / herself and must be handled by the manufacturer or assembler according to the customer's needs. Thus, the timeliness and operation are not convenient. The above problems need to be improved. UTILITY MODEL CONTENTS
