Description

Technical Field

[0001] This utility model relates to the field of component puller technology, specifically a component puller to prevent component detachment. Background Technology

[0002] A keycap puller is a specialized tool used for removing keycaps in mechanical keyboard maintenance. Its core structure typically includes an arc-shaped connecting part and symmetrically distributed clamping parts. In use, the clamping parts are pressed to retract and clamp the sidewall of the keycap, and then the connecting part is pulled to separate the keycap from the key switch.

[0003] However, existing keycap pullers have significant keycap detachment issues in practical use. Firstly, traditional clamping mechanisms only make linear contact with the keycap's sidewall, making them prone to disengagement due to uneven force during lifting, especially when removing smooth keycaps, where the detachment rate increases significantly. Secondly, the lack of an effective top-mounted retaining structure allows keycaps to slip due to axial force during lifting. Furthermore, some pullers simplify their clamping structure in pursuit of versatility, resulting in insufficient contact with the keycap and further exacerbating the risk of detachment. These problems can not only damage keycaps or key switches but also negatively impact user experience and operational efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a keycap puller to prevent keycaps from falling off, which can effectively solve the technical problem that keycaps are easily detached when the keycaps are pulled out by the currently used keycap pullers.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A keycap puller for preventing keycap detachment includes an arc-shaped connecting part and two clamping parts. The two clamping parts are symmetrically connected to both ends of the connecting part for pressing and clamping the keycap. The end of each clamping part away from the connecting part is provided with a barb for fixing to the bottom of the keycap. The barb is distributed on the opposite side of the two clamping parts. Each clamping part is also provided with a flip piece located above the barb for adhering to the outside of the keycap. One end of the flip piece is connected to the clamping part via a pivot, allowing the flip piece to rotate along the axis of the pivot. A torsion spring is sleeved on the outside of the pivot to provide elasticity so that the flip piece adheres to the outside of the keycap. One end of the torsion spring is fixed to the flip piece, and the other end is fixed to the clamping part. A patch is provided between the two flip pieces for adhering to and fixing to the top of the keycap. The patch is connected to the flip pieces on both sides via an elastic strip.

[0007] Furthermore, an anti-slip part is provided on the outer side of the clamping part.

[0008] Furthermore, the inner side of the clamping part is provided with a mounting groove for mounting the rotating shaft, and one end of the flipping piece is embedded in the mounting groove.

[0009] Furthermore, the elastic strip is provided with four strips, and the two ends of the patch are respectively connected to the corresponding flip piece through two elastic strips.

[0010] Furthermore, the inner side of the connecting part is provided with holes for suspension.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The keycap puller provided by this utility model uses a barb, a flip piece, and a patch to fix the bottom, side, and top of the keycap in sequence when clamping it, making it less likely for the keycap to move or fall off when pulled out, thus improving the stability of the keycap when it is pulled out.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5As shown, this utility model provides a keycap puller to prevent keycaps from falling off, which effectively solves the problem that traditional keycap pullers used for keycaps are prone to falling off and damaging the keycaps. It is especially suitable for disassembling and assembling high-precision keycaps such as those on mechanical keyboards.

[0024] The keycap puller has an arc-shaped connecting part 1 and two symmetrically connected clamping parts 2. The connecting part 1 is an arc-shaped structure formed by bending an elastic metal sheet. Its two ends are integrally formed with the clamping parts 2. When in use, pressing the clamping parts 2 causes both to retract inward to clamp the keycap.

[0025] Each clamping part 2 has a barb 3 on its inner side at the end furthest from the connecting part 1. The barb 3 is a protruding structure that engages with the bottom slot of the keycap to achieve initial fixation. To enhance clamping stability, a flip piece 4 is also provided on the inner side of the clamping part 2. The flip piece 4 is movably connected to the clamping part 2 via a rotating shaft 5. Specifically, a cylindrical mounting groove 201 is formed on the inner side of the clamping part 2. The rotating shaft 5 passes through both side walls of the mounting groove 201. One end of the flip piece 4 is embedded in the mounting groove 201 and can rotate around the axis of the rotating shaft 5.

[0026] A torsion spring 6 is fitted on the outer side of the rotating shaft 5. One end of the torsion spring 6 is fixed in the mounting groove 201 of the clamping part 2, and the other end is fixed to the flip piece 4. In its natural state, the elastic force of the torsion spring 6 drives the flip piece 4 to flip outward to form a certain angle with the clamping part 2, ensuring that the outer side of the flip piece 4 is tightly attached to the side wall of the keycap.

[0027] A patch 7 is provided between the two flip pieces 4. The patch 7 is an arc-shaped thin sheet of silicone material, and its two ends are connected to the corresponding flip piece 4 by two elastic strips 8. In this embodiment, the elastic strips 8 are made of highly elastic rubber strips, with two symmetrically arranged on each side. When the keycap is clamped, the elastic strips 8 are deformed under pressure, driving the patch 7 to adhere tightly to the top of the keycap, forming a three-point fixing structure of "barb 3 - flip piece 4 - patch 7".

[0028] The clamping part 2 has an anti-slip part 9 on its outer side, which increases the friction of the hand during operation and helps to manually press the clamping part 2. In addition, a hanging hole 101 is provided on the inner side of the connecting part 1, which facilitates hanging and placement.

[0029] When in use, the user presses the clamping part 2 with both hands to make the barb part 3 snap into the bottom of the keycap. At this time, the flip piece 4 automatically fits the side wall of the keycap under the action of the torsion spring 6. The elastic strip 8 deforms to make the patch 7 press the top of the keycap. When pulled upward, the barb part 3 bears the vertical pulling force, and the flip piece 4 and the patch 7 bear the lateral friction force, forming a three-dimensional anti-detachment structure.

[0030] Compared with traditional technology, the keycap puller provided by this technical solution fixes the bottom, side and top of the keycap in sequence through the barb 3, the flip piece 4 and the patch 7 when clamping the keycap, making it less likely for the keycap to move or fall off when pulled out, which helps to improve the stability of the keycap when pulled out.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
