Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools technology, and in particular to an auxiliary tool for quickly threading bicycle gear cables. Background Technology

[0002] Threading the derailleur cables in bicycle assembly refers to the process of installing the derailleur cables (usually composed of steel wires and sheaths) onto the frame according to a specific route and method. This process ensures that the derailleur cables can correctly transmit the operating signals from the shifters, controlling the movement of the front and rear derailleurs, thereby achieving accurate gear shifting. The quality of the threading directly affects the smoothness, accuracy, and durability of the derailleur system. Traditionally, threading bicycle derailleur cables usually requires manual labor and tools such as magnets to slowly guide the cables through the process. This method is not only inefficient but also causes worker fatigue during prolonged threading, thus affecting overall threading efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tool for quickly threading bicycle gear cables.

[0004] This utility model is achieved using the following technical solution:

[0005] A quick-threading aid for bicycle gear cables includes a traction mechanism, a fixing mechanism, and a protective mechanism. The traction mechanism is located inside the protective mechanism, and the fixing mechanism is located at the lower end of the protective mechanism.

[0006] The traction mechanism includes a take-up motor, the output end of which is fixedly connected to a rotating reel. A support frame is rotatably connected to the surface of the rotating reel, and a traction cable is wound around the surface of the rotating reel. A mounting frame is provided on the left side of the support frame, and a limit rubber sleeve is rotatably connected to the inner wall of the mounting frame. A drive rubber sleeve is rotatably connected to the inner wall of the mounting frame, and a pay-off motor is fixedly connected to the front end of the drive rubber sleeve. A connecting sleeve is fixedly connected to the left end of the traction cable, and a limit screw is threadedly connected to the inner wall of the connecting sleeve.

[0007] The design utilizes the rotation of the drive rubber sleeve to extend the traction steel cable and the rotation of the rotating reel to retract the speed change cable connected to the connecting sleeve. This achieves the purpose of quickly threading the speed change cable, making the device more convenient to use.

[0008] In a further improvement, the lower end of the limiting rubber sleeve contacts the upper end of the traction steel cable, and the upper end of the driving rubber sleeve contacts the lower end of the traction steel cable.

[0009] In a further improvement, the fixing mechanism includes a fixed base frame, a rotating shaft rotatably connected to the inner wall of the fixed base frame, a rotating frame fixedly connected to the surface of the rotating shaft, and a buckle fixedly connected to the lower end of the rotating frame.

[0010] The design, which uses the rotation of the two rotating brackets to fix the entire device to the frame, makes subsequent wiring work more convenient and improves the practicality of the device.

[0011] In a further improvement, the number of rotating frames is two, and the rotating frames are symmetrically distributed at the center of the fixed base frame.

[0012] In a further improvement, the protective mechanism includes a protective shell, a protective top plate fixedly connected to the upper end of the protective shell, a control button fixedly connected to the front end of the protective shell, and a motor bracket fixedly connected to the inner wall of the protective shell.

[0013] It provides stable protection for the use of the device, preventing damage to internal parts during use and improving the device's practicality.

[0014] In a further improvement, the lower end of the protective shell is fixedly connected to the upper end of the fixed base frame, the control button is connected to the winding motor, and the control button is connected to the unwinding motor.

[0015] In a further improvement, the left end of the mounting bracket is fixedly connected to the inner wall of the winding motor, the lower end of the winding motor is fixedly connected to the upper end of the motor bracket, the left end of the unwinding motor is fixedly connected to the inner wall of the protective shell, and the connecting sleeve is located at the left end of the protective shell.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, the connecting sleeve on the left is placed into the hole to be threaded, and then the control button is pressed to start the wire feeding motor to rotate, which in turn drives the driving rubber sleeve to rotate. This works in conjunction with the upper limiting rubber sleeve to clamp and feed the traction steel cable into the hole. When the connecting sleeve reaches the hole outlet, the rotation of the wire feeding motor stops. Then, the variable speed cable is inserted into the inside of the connecting sleeve, and the limiting screw is rotated to fix the variable speed cable on the inner wall of the connecting sleeve. After fixing, another button of the control button is pressed to control the rotation of the winding motor, which drives the rotating reel to rotate, thereby driving the traction steel cable to wind up. At the same time as the traction steel cable winds up, the variable speed cable connected to the connecting sleeve is also retracted, thus quickly threading the variable speed cable. The design of using the rotation of the driving rubber sleeve to drive the traction steel cable to extend and using the rotation of the rotating reel to drive the variable speed cable connected to the connecting sleeve to retract achieves the purpose of quickly driving the variable speed cable to thread, making the device more convenient to use. Unlock the buckles to release the restrictions on the rotating brackets on both sides. Then, place the tool as a whole into the desired threading position from the rotating brackets. After placing it in the desired position, reassemble the rotating brackets on both sides and fasten the buckles again to fix the entire device onto the frame for subsequent threading. The design of using the rotation of the rotating brackets on both sides to fix the entire device onto the frame makes subsequent threading work more convenient and improves the practicality of the device.

[0025] The traction mechanism 1 includes a take-up motor 101, with a rotating reel 102 fixedly connected to the output end of the take-up motor 101. A support frame 103 is rotatably connected to the surface of the rotating reel 102, and a traction cable 104 is wound around the surface of the rotating reel 102. A mounting frame 108 is provided on the left side of the support frame 103. A limiting rubber sleeve 105 is rotatably connected to the inner wall of the mounting frame 108, and a driving rubber sleeve 106 is rotatably connected to the inner wall of the mounting frame 108. A pay-off motor 107 is fixedly connected to the front end of the driving rubber sleeve 106, and a connecting sleeve 109 is fixedly connected to the left end of the traction cable 104. A limiting screw 110 is threadedly connected to the inner wall of the connecting sleeve 109. The design uses the rotation of the driving rubber sleeve 106 to drive the traction cable 104 to extend and the rotation of the rotating reel 102 to drive the speed-changing cable connected to the connecting sleeve 109 to retract, achieving the purpose of quickly driving the speed-changing cable for threading and making the device more convenient to use.

[0026] The lower end of the limiting rubber sleeve 105 contacts the upper end of the traction steel cable 104, and the upper end of the driving rubber sleeve 106 contacts the lower end of the traction steel cable 104.

[0027] The fixing mechanism 2 includes a fixing base 201, a rotating shaft 202 is rotatably connected to the inner wall of the fixing base 201, a rotating frame 203 is fixedly connected to the surface of the rotating shaft 202, and a buckle 204 is fixedly connected to the lower end of the rotating frame 203. The design of using the rotation of the rotating frames 203 on both sides to fix the device to the frame as a whole achieves the purpose of making the subsequent wiring work more convenient and improving the practicality of the device.

[0028] There are two rotating frames 203, which are symmetrically distributed at the center of the fixed base frame 201.

[0029] The protective mechanism 3 includes a protective housing 301, a protective top plate 302 fixedly connected to the upper end of the protective housing 301, a control button 303 fixedly connected to the front end of the protective housing 301, and a motor bracket 304 fixedly connected to the inner wall of the protective housing 301.

[0030] The lower end of the protective shell 301 is fixedly connected to the upper end of the fixed base frame 201. The control button 303 is connected to the winding motor 101 and the unwinding motor 107.

[0031] The left end of the mounting bracket 108 is fixedly connected to the inner wall of the winding motor 101, the lower end of the winding motor 101 is fixedly connected to the upper end of the motor bracket 304, the left end of the wire feeding motor 107 is fixedly connected to the inner wall of the protective shell 301, and the connecting sleeve 109 is located at the left end of the protective shell 301.

[0032] The working principle is as follows: First, open the buckle to release the limiting position of the rotating frames 203 on both sides. Then, place the tool as a whole into the desired threading position from the rotating frames 203. After placing it into the desired position, reassemble the rotating frames 203 on both sides and fasten the buckle again to fix the entire device onto the frame for subsequent threading. The design of using the rotation of the rotating frames 203 on both sides to fix the entire device onto the frame makes the subsequent threading work more convenient and improves the practicality of the device. After the device is fixed, first place the connecting sleeve 109 on the left side into the hole to be threaded. Then, press the control button 303 to start the wire feeding motor 107 to rotate, which in turn drives the drive rubber sleeve 106 to rotate. This works in conjunction with the upper limiting rubber sleeve 105 to clamp and feed the traction steel cable 104 into the hole. When the wire is delivered to the hole outlet, the rotation of the wire feeding motor 107 is stopped. Then, the speed change wire is inserted into the inside of the connecting sleeve 109. Then, the limit screw 110 is rotated to fix the speed change wire on the inner wall of the connecting sleeve 109. After fixing, the other button of the control button 303 is pressed again to control the winding motor 101 to rotate, thereby driving the rotating reel 102 to rotate, thereby driving the traction cable 104 to wind up. While the traction cable 104 is winding up, the speed change wire connected to the connecting sleeve 109 is also wound up, thereby quickly threading the speed change wire. The design of using the rotation of the drive rubber sleeve 106 to drive the traction cable 104 to extend and using the rotation of the rotating reel 102 to drive the speed change wire connected to the connecting sleeve 109 to retract achieves the purpose of quickly driving the speed change wire to thread up, making the device more convenient to use.
