Description

Technical Field

[0001] This utility model relates to the field of pin assembly and disassembly technology, and in particular to a short shaft pin remover. Background Technology

[0002] A baitcasting reel is a fishing reel that is named for its teardrop-like shape. Inside the baitcasting reel is a spool. After long-term use, the ball bearings and raceways in the spool will gradually wear down due to friction, resulting in increased clearance, decreased rotational accuracy, and shaking or abnormal noise. This affects the smoothness and stability of the spool's rotation, and at this time, the bearing in the spool needs to be replaced.

[0003] The spool has a column at its center, and the bearing is installed in the column near the end. The end of the column has a pin. When replacing the bearing, the pin at the end of the column needs to be removed and installed. In the prior art, using tools to remove and install the pin can easily damage the spool, and the removal and installation of the pin is slow. Utility Model Content

[0004] In order to solve the technical problems of easy collision with the spool when disassembling and assembling the pin in the prior art, and the slow speed of disassembling and assembling the pin, this utility model provides a short shaft pin remover.

[0005] The short shaft pin remover provided by this utility model adopts the following technical solution:

[0006] A short shaft pin remover includes a pin removal block with a through-groove inside. A disassembly component for removing the pin is slidably disposed inside the disassembly groove. A flat-headed short pin and a long pin are located at the bottom of the disassembly component. A first long groove is located at the bottom of the disassembly groove opposite the flat-headed short pin, and a second long groove is located at the bottom of the disassembly groove opposite the long pin. A pushing mechanism is located on the upper part of the pin removal block to push the disassembly component downwards. The pushing mechanism pushes the disassembly component to slide towards the bottom of the disassembly groove, causing the flat-headed short pin to push the protruding end of the pin into the cylinder inside the spool. The pushing mechanism further pushes the disassembly component to slide towards the bottom of the disassembly groove, causing the long pin to push the pin outwards from the cylinder inside the spool, thus detaching the pin from the cylinder.

[0007] Furthermore, the disassembly block is a square structure with a certain thickness.

[0008] Furthermore, the disassembly assembly includes a slider and a flat-headed short pin and a long pin disposed at the bottom of the slider, the slider being slidably disposed inside the disassembly groove.

[0009] Furthermore, connecting shafts are respectively provided on both sides inside the disassembly groove, and the slider is slidably connected to the connecting shafts, thereby slidably setting the slider inside the disassembly groove.

[0010] Furthermore, the bottom of the slider has a first protrusion and a second protrusion protruding outwards. The first protrusion and the second protrusion are disposed on two opposite sidewalls of the slider. There are multiple flat-headed short pins. The multiple flat-headed short pins are longitudinally disposed at the first protrusion position at the bottom of the slider. The long pins protrude outwards and are disposed at the second protrusion position at the bottom of the slider.

[0011] Furthermore, fixed inclined surfaces are provided at the positions where the upper parts of the first and second long grooves contact the bottom wall of the disassembly groove.

[0012] Furthermore, the propulsion mechanism includes a stud and a handle. The stud extends into the disassembly groove after passing through the center of the upper wall of the disassembly block. The stud and the upper wall of the disassembly block form a threaded connection. A spring surrounds the outer wall of the connecting shaft. One end of the spring abuts against the bottom of the disassembly groove, and the other end of the spring abuts against the bottom wall of the slider. A connecting groove is provided at the center of the upper surface of the slider. Under the elastic force of the spring, the slider slides upward along the outer wall of the connecting shaft, thereby embedding the bottom of the stud into the connecting groove at the top of the slider.

[0013] Furthermore, a handle is fixedly provided at the end of the stud away from the disassembly block. By rotating the handle, the stud moves towards the bottom of the disassembly groove, and at the same time, the stud pushes the slider to move towards the bottom of the disassembly groove.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] In use, this invention involves placing the disassembly block at the pin position on the upper part of the main body of the spool, ensuring the fixed inclined surface at the top of the first long groove contacts the central column of the spool. Then, align the flat-headed short pin with the protruding end of the pin. Rotating the handle in the pushing mechanism causes the stud to push the slider towards the first long groove, thus pushing the protruding end of the pin into the column with the flat-headed short pin at the bottom of the slider. Next, flip the disassembly block so that the fixed inclined surface at the top of the second long groove contacts the central column of the spool, aligning the long pin with the pin position on the upper part of the main body. Rotating the handle in the pushing mechanism causes the stud to push the slider towards the second long groove, thus pushing the pin outward from the column in the spool. At this point, the bearing in the spool can be removed. After replacing the bearing, place the disassembly block on top of the bearing, so that the fixed inclined surface at the top of the first long groove contacts the column in the center of the spool. Place the pin in the installation position on the column, and turn the handle to press the pin through the flat-headed short pin at the bottom of the slider, thus installing the pin on the column in the spool, thereby completing the replacement of the spool bearing. In use, this utility model uses the fixed inclined surface at the top of the first and second long grooves in contact with the column in the center of the spool as a fixing point. The flat-headed short pin and the long pin work together to disassemble and install the pin on the main body of the spool. This short shaft pin disassembly tool will not damage the spool during use and improves the speed of pin disassembly and installation, thereby improving the speed of spool bearing replacement.
