Description

Technical Field

[0001] The utility model relates to the technical field of clutch handles, in particular to a labor-saving clutch handle. Background Art

[0002] The clutch handle, also known as the clutch operating handle or clutch lever, is an important component for controlling the clutch. It is mostly used on motorcycles to regulate the working state of the clutch and achieve connection and disconnection between the engine and the transmission system.

[0003] The clutch handle is usually composed of a handle body, a connecting rod, a base and other parts. When operating the clutch handle, the user presses the handle rod with his hand, and the handle rod rotates around the shaft and pulls the clutch cable, which pulls the clutch switch open and closed through the clutch cable, thereby achieving the effect of controlling the clutch. However, the force of existing clutch handles is mostly fixed, and a fixed force needs to be used to press the clutch handle to achieve the effect of controlling the clutch. For users of different physiques, the pressing force they are accustomed to is different, and the clutch handle is not convenient for adjusting the pressing force, so a labor-saving clutch handle is proposed.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1 to 5 , a labor-saving clutch handle comprises a main board 1, a fixing frame 2 is provided on the rear side of the main board 1, a center rod 3 is provided in the middle of the main board 1, the outer surface of the center rod 3 is rotatably connected to a connecting plate 4, and a friction plate 11 is provided at the junction of the center rod 3 and the connecting plate 4, so that stability during rotation is avoided. A grip 5 is fixed on the outer surface of the connecting plate 4, and the bending amplitude of the grip 5 is convenient for hand holding. A pulley 6 is provided on the side of the main board 1, and a track 10 is opened inside the pulley 6. A ball 9 is provided on the side of the main board 1, and the ball 9 slides in the track 10. When the pulley 6 is rotated, the ball 9 slides in the track 10 with a ticking sound, and the feedback is relatively obvious. An electronic switch box 7 is provided on the upper part of the main board 1, and an adjustment component 8 is provided on the side of the connecting plate 4 close to the main board 1. The specific structure and working principle of the handle are the existing technology well known to the staff in this field, and will not be elaborated in detail here.

[0024] Reference Figure 1 、 Figure 2 and Figure 3 The adjusting component 8 includes a plug-in 801 arranged in the middle of the connecting plate 4, and an iron piece 802 is slidingly provided on the upper part of the plug-in 801. The bottom end of the iron piece 802 is fixedly connected to the insertion rod 803, and the upper surface of the iron piece 802 is fixedly connected to the protrusion 804. A positioning bolt 805 is provided at the edge of the upper surface of the connecting plate 4. The positioning bolt 805 is pressed on the upper surface of the iron piece 802. Loosen the positioning bolt 805 and then push the protrusion 804 to drive the iron piece 802 to slide on the upper part of the plug-in 801. At this time, the insertion rod 803 also slides inside the plug-in 801, and the position of the clutch line can be adjusted. After the adjustment is complete, tighten the positioning bolt 805. According to the distance of the lever, the more outward the plug-in 801 moves, the more effort is saved, thereby achieving the effect of adjusting the force of pressing the grip.

[0025] Reference Figure 2 、 Figure 4 and Figure 5, a hollow box 12 is provided at the front end of the main board 1, and a shaft 14 is connected to the interior of the hollow box 12 for rotation. A support rod 13 is provided at the front end of the connecting plate 4, and a rope 15 is provided on the outer surface of the shaft 14. The end of the rope 15 away from the shaft 14 is fixedly connected to the middle of the support rod 13, and a torsion spring 17 is provided on the outer surface of the shaft 14. A lever 16 is fixedly connected to the outer surface of the shaft 14. A sound ball 20 is fixedly connected to the inner wall of the hollow box 12, and a collision ball 18 is movably connected to the middle part of the lever 16. A spring 19 is provided on the rear side of the collision ball 18. In the process of pressing the grip, the connecting plate 4 rotates around the center rod 3 so that the support rod 13 is away from the hollow box 12. At this time, the support rod 13 pulls the rope 15, and the movement of the rope 15 drives the shaft rod 14 to rotate and squeezes the torsion spring 17. The shaft rod 14 rotates and drives the dial rod 16 to rotate. During the rotation of the dial rod 16, the collision ball 18 contacts and collides with the ringing ball 20, and then makes a collision sound, realizing the information feedback achieved by pressing the grip rod. When the grip 5 is released, the connecting rod is reset, and the torsion spring 17 rebounds and drives the shaft rod 14 to flip and stretch and rewind. At the same time, the rotation of the dial rod 16 also drives the collision ball 18 to collide with the ringing ball 20, and information feedback is performed again to help the rider judge the state of the clutch more accurately.

[0026] The specific working principle of the present invention is as follows: when the device is in use, the positioning bolt 805 is loosened, and then the protrusion 804 is pushed to drive the iron sheet 802 to slide on the upper part of the plug-in 801. At this time, the plug-in rod 803 also slides inside the plug-in 801, and the position of the clutch line can be adjusted. After the adjustment is complete, the positioning bolt 805 is tightened. According to the distance between the lever and the plug-in 801, the more outward it moves, the more effort is saved, thereby achieving the effect of adjusting the force of pressing the grip. In the process of pressing the grip, the connecting plate 4 rotates around the center rod 3 so that the support rod 13 is away from the hollow box 12. At this time, the support rod 13 pulls the rope 15, and the movement of the rope 15 drives the shaft rod 14 to rotate and squeeze the torsion spring 17. When the shaft rod 14 rotates, it will drive the lever 16 to rotate. During the rotation of the lever 16, the collision ball 18 will contact and collide with the ringing ball 20, and then make a collision sound, realizing the information feedback achieved by pressing the grip rod. When the grip 5 is released, the connecting rod is reset, and the torsion spring 17 rebounds to drive the shaft rod 14 to flip and stretch and rewind. At the same time, the rotation of the lever 16 also drives the collision ball 18 to collide with the ringing ball 20, and information feedback is performed again to help the rider judge the state of the clutch more accurately.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
