Description

Technical Field

[0001] The utility model relates to the technical field of shaft pullers, and specifically, to a disassembly mechanism for a shaft puller. Background Technique

[0002] A shaft puller is a tool used for the modification and repair of mechanical keyboards, mainly used to remove the shaft bodies on the circuit board from the keyboard. The shaft puller is usually made of metal or plastic and has different shapes and sizes to adapt to different types and brands of mechanical keyboards. Its design requirements are to precisely fit the shaft bodies while avoiding damage to other components on the keyboard, such as the PCB board and keycaps. When the existing shaft puller disassembles the keycaps and shaft bodies, it usually needs to clamp the keycaps and shaft bodies with an elastic piece and then pull the shaft puller upward, so that the shaft puller drives the keycaps and shaft bodies to be pulled out through the elastic piece. During the pulling-out process, it cannot always maintain a vertical state, which may cause damage to the keycaps and shaft bodies. Therefore, it is necessary to provide a disassembly device that can pull the keycaps and shaft bodies vertically upward to complete the disassembly of the keycaps and shaft bodies.

During the pulling-out process, it cannot always maintain a vertical state, which may cause damage to the keycaps and shaft bodies.

[0004] The utility model is a disassembly mechanism for a shaft puller, including:

[0005] A support component, the support component includes a housing;

[0006] A disassembly component, the disassembly component includes a first movable block, a top plate, a second movable block, a rack, a support shaft, a gear, a second hollow groove, an elastic piece and a bottom plate;

[0018] By providing a disassembly assembly, by snapping the bottom plate into both sides of the keycap and making the bottom plate fit with the upper end of the keyboard, and then making the elastic sheet be located at the other two sides of the keycap, by rotating the gear, while the gear rotates along the support shaft, it drives the rack to move upwards, the rack drives the first movable block to move upwards, and drives the second movable block to move upwards through the top plate. During the upward movement of the first movable block and the second movable block, they always maintain a vertical state, so that the first movable block and the second movable block drive the elastic sheet to move vertically upwards, thereby making the keycap and the shaft body move vertically upwards, so that damage caused by the keycap and the shaft body being pulled out obliquely during disassembly can be avoided;

[0019] Meanwhile, by setting the movable component, when the elastic sheet needs to be replaced, the baffle is squeezed inward to drive the movable column to move inward. When the movable column moves inward, the limiting column moves inward and moves the elastic sheet downward until it contacts the outer surface of the movable column. Then the baffle is released, causing the movable column to rebound outward. The limiting column will not move outward under the block of the elastic sheet, and the limiting column will not penetrate and block the elastic sheet, so that the elastic sheet can be removed from the outer ends of the first movable block and the second movable block.

[0044] As Figure 4 shown, based on the same concept as the above-mentioned Embodiment 1, it further includes:

[0045] A movable assembly, which includes a hollow circular groove 31, a first telescopic spring 32, a limit post 33, a movable column 34, a second telescopic spring 35 and a baffle 36;

[0046] The hollow circular groove 31 is opened at the outer side of the lower ends of the first movable block 21 and the second movable block 23. The first telescopic spring 32 is fixedly connected inside the hollow circular groove 31. The limit post 33 is fixedly connected to the outer end of the first telescopic spring 32. The movable column 34 is placed inside the through hole 13. The second telescopic spring 35 is fixedly connected to the outer side of the lower end of the housing 11. The baffle 36 is fixedly connected to the outer end of the movable column 34;

[0047] The hollow circular groove 31 is used to place the first telescopic spring 32 and the limit post 33. The first telescopic spring 32 is used to reset the limit post 33. The limit post 33 is used to limit the elastic sheet 28. The movable column 34 is used to drive the limit post 33 to move. The second telescopic spring 35 is used to drive the baffle 36 to reset. The baffle 36 is used to support the second telescopic spring 35;

[0052] Working principle: When the elastic piece 28 needs to be replaced, an inward force is applied to the baffle 36. The inward movement of the baffle 36 drives the movable column 34 to move inward, and drives the second telescopic spring 35 to be compressed to generate elastic force. When the movable column 34 moves inward, the limit column 33 moves out of the inside of the elastic piece 28 and enters the inside of the hollow circular groove 31, and at the same time drives the first telescopic spring 32 to be compressed. At this time, the elastic piece 28 is moved downward. The elastic piece 28 moves to the inner side of the outer end of the limit column 33 and contacts the outer surface of the movable column 34. Then, the force applied to the baffle 36 is stopped. The movable column 34 moves outward under the elastic force of the second telescopic spring 35. The outward movement of the movable column 34 does not block the elastic piece 28, and the elastic piece 28 blocks the limit column 33. Continuing to apply a downward force to the elastic piece 28 can remove the elastic piece 28 from the inside of the housing 11;

[0053] When the elastic piece 28 needs to be installed, just operate the above steps in reverse.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
