Description

Technical Field

[0001] The utility model is applied to the technical field of keyboard key tools, and particularly relates to a multifunctional shaft puller. Background Art

[0002] Keyboard devices are commonly used computer input devices that can input characters or interact with computers. Keyboards of different types and models will have different feel when used. In order to meet the user's stylized and customized keyboard feel, private keyboards can now be assembled in the form of DIY keyboards, and key shafts with different pressure values ​​and paragraph structures can be selected according to their own habits. You can also DIY the keyboard circuit board according to your needs, and then obtain a customized keyboard with a layout that suits your usage habits. At the same time, the thickness of the circuit board will also have different degrees of influence on the vibration and press feedback during operation. The keycaps are a channel to display the stylized appearance. By replacing the keycaps, you can get different keyboard appearance combinations.

[0003] The key shaft, keycaps and keyboard circuit boards may often be replaced during customized use to meet the needs of different periods or different working environments. However, in order to ensure stability during use, the key shaft is usually provided with a snap-on structure that cooperates with the circuit board or positioning plate on its shaft seat, and it cannot be easily pulled out. A shaft puller or other similar tools are required to easily pull out the key shaft or keycap. Therefore, a shaft puller is a tool commonly used by customized users. However, ordinary shaft pullers can only meet the needs of pulling out key shafts and keycaps. For example, the disassembly of key shafts and keycaps, stroke inspection, keyboard circuit board thickness inspection, etc. all require different tools to handle. It is often necessary to frequently modify and adjust the customized keyboard, and it is also necessary to be equipped with a variety of different tools to operate.

[0004] If a tool that can perform multiple customized keyboard adjustment operations can be provided, it can effectively solve the problem of inconvenience faced by keyboard customization users during the adjustment process. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a multifunctional shaft puller with multiple customized keyboard adjustment operations.

[0007] As can be seen from the above scheme, a pair of hinged main bodies can open and close, thereby loosening or clamping the key shaft or keycap, wherein the pressing protrusions arranged at the main working end of the main body can cooperate with the mounting buckles that limit the connection between the two sides of the key shaft and the circuit board or the positioning plate, and then release the limit by pressing the mounting buckle and clamp the key shaft through the cooperation of the two main bodies to pull it out. By setting the clamping assembly, various components can be replaced on the basis of the existing shaft puller, and corresponding functions can be obtained through clamping assemblies of different shapes, such as pulling out keycaps of different sizes or multiple keycaps at the same time, or pulling out a single keycap, or providing more stable key shaft pulling out, etc., which can more conveniently use multiple functions without using different tools for processing each time. The existing shaft puller that integrates the key shaft extraction and keycap extraction functions is usually a U-shaped elastomer structure, and the two tools are respectively arranged at the two ends. When in use, it is necessary to press the elastomer hard to clamp it. On the one hand, the overall size is relatively long, and on the other hand, it is more laborious to use. It is easy to rebound when the applied force is not enough. The present application uses a driving method of an articulated lever arm, which can be operated more labor-savingly. At the same time, the extraction function is concentrated on the same end, and the overall structure is more compact.

[0008] A preferred solution is that the clamping assembly includes a clamping block and a clamping block arranged on the inner side of the clamping block, the clamping block includes an inner shaft segment and an outer shaft segment that are integrally formed, the inner shaft segment and the outer edge of the outer shaft segment cooperate to form a step shape, and the clamping groove includes a first through hole and a second through hole that are connected, the first through hole is adapted to the outer shaft segment, and the second through hole is adapted to the inner shaft segment.

[0009] A further preferred solution is that the clamping block is also provided with a limiting hook which cooperates with the main body to limit the position.

[0010] A further preferred solution is that both sides of the clamping block are provided with limiting ribs, and the two limiting ribs cooperate with the main working end of the main body to form a concave limiting structure.

[0011] A further preferred solution is that an extension piece is provided at one end of the clamping block away from the clamping block, and a hook is provided at the end of the extension piece.

[0012] A further preferred solution is that the width of the end of the extension piece is greater than the width of the clamping block.

[0013] A preferred solution is that a plurality of circuit board thickness detection grooves are arranged at intervals on the secondary working end of the main body.

[0014] A preferred solution is that two adjacent circuit board thickness detection grooves cooperate to form an axial stroke measurement baffle, and a stroke measurement hole adapted to the key shaft core is provided on the side of the auxiliary working end of the main body, and the key shaft core passes through the stroke measurement hole and cooperates with the axial stroke measurement baffle to limit the position.

[0015] Another technical solution provided by the utility model is: the utility model includes a pair of main bodies that are hingedly matched with each other, the main working ends of the two main bodies are each provided with a pressing protrusion that cooperates with the mounting buckle of the key shaft, the secondary working end of the main body is provided with a buckle disassembly block, the outer end of the buckle disassembly block is provided with a guiding inclined surface, when the two main bodies are closed, the two buckle disassembly blocks contact the connecting buckles on both sides of the key shaft correspondingly, and the connecting buckles are deformed outward along the guiding inclined surface.

[0016] It can be seen from the above scheme that the key shaft body is composed of a shaft core, a conductive metal sheet, an elastic member, a shaft cover and a base, wherein the shaft core, the conductive metal sheet and the elastic member are all encapsulated in the shaft cover and the base, and the shaft core can move up and down in the shaft cover and the base, and the shaft cover and the base are fixed together by the connecting buckles on both sides of the key shaft body. The shaft cover and the base need to be separated in order to lubricate or repair the shaft core. The key shaft body can be opened through the above structure, and then on the basis of the function of the shaft puller, the shaft opening function can be further combined, so that users can more conveniently perform keyboard customization operations and later maintenance.

[0028] Embodiment 1:

[0029] like Figure 1 As shown, in this embodiment, the utility model includes a pair of main bodies 1 and a plurality of pairs of clamping assemblies 4 which are hingedly matched with each other. The main working ends of the two main bodies 1 are each provided with a pressing protrusion 3 which cooperates with the button shaft mounting buckle 2. The main working ends of the main bodies 1 are also provided with a card slot 5, and the clamping assembly 4 is detachably connected to the card slot 5.

[0030] like Figures 1 to 3 As shown, in this embodiment, the clamp assembly 4 includes a clamp block 41 and a clamp block 42 disposed inside the clamp block 41, the clamp block 42 includes an inner shaft section 421 and an outer shaft section 422 formed integrally, the inner shaft section 421 cooperates with the outer edge of the outer shaft section 422 to form a step shape, the clamping slot 5 includes a first through hole 51 and a second through hole 52 that are connected, the first through hole 51 is adapted to the outer shaft section 422, and the second through hole 52 is adapted to the inner shaft section 421. The clamp block 41 is also provided with a limit hook 411 that is limitedly matched with the main body 1. The clamp block 41 is used to clamp the key shaft body or key cap through the stepped edge of the clamp block 42, so that when it moves from the first through hole 51 to the second through hole 52, the outer shaft section 422 will cooperate with the clamp block 41 so that the inner shaft section 421 is clamped in the second through hole 52. The second through hole 52 is located on the side of the first through hole 51 close to the pressing protrusion 3, and when the shaft is pulled out, the clamping block 41 will move toward the direction of the second through hole 52 under the reaction force of the shaft body, ensuring that the clamping block 41 will not be separated during use. In addition, the clamping block 41 is clamped on the main body 1 in cooperation with the clamping block 42 through the limiting hook 411. When replacing the clamping block 41, the clamping block 41 is deformed by applying pressure to release the limiting hook 411 and the main body 1, and then the clamping block 41 is moved toward the direction of the first through hole 51 to achieve separation, and vice versa, the clamping block 41 can be installed.

[0031] In this embodiment, the outer side surface of the clamp block 41 is also provided with anti-slip patterns in an array, so as to facilitate the installation of the clamp block 41 .

[0032] like Figures 1 to 3 As shown, when the clamp block 41 is used to pull out the key shaft, both sides of the clamp block 41 are provided with limiting ribs, and the two limiting ribs cooperate with the main working end of the main body 1 to form a concave limiting structure. By combining the concave limiting structure, when the pressing protrusion 3 presses the key shaft installation buckle 2, the limiting structure covers and limits the edges of both sides of the key shaft, thereby ensuring the support of the key shaft as a whole when pulling out the shaft, and realizing stable and reliable pulling out of the shaft.

[0033] like Figure 4 and Figure 5 As shown, when the clamping block 41 is used to pull out the keycap, an extension piece 412 is provided at one end of the clamping block 41 away from the clamping block 42, and a hook 413 is provided at the end of the extension piece 412. The extension piece 412 is a thin piece that can easily extend into the gap between the keycaps, and the hook 413 can clamp the edge of the keycap when clamping and pull the keycap out of the key shaft.

[0034] like Figure 6 and Figure 7 As shown, based on the clamping block solution for pulling out the keycaps, the width of the end of the extension piece 412 is greater than the width of the clamping block 41. This solution can realize the simultaneous pulling out of multiple keycaps. When the width of the clamping block 41 is the width of a standard keycap and the width of the end of the extension piece 412 is the width of two standard keycaps, two keycaps or long keycaps can be pulled out. Further increasing the width of the extension piece 412 can further increase the number of keycaps that can be pulled out, thereby improving the operating efficiency and enabling fast operation.

[0035] like Figure 8 As shown, in the present embodiment, a plurality of circuit board thickness detection slots 7 are arranged at intervals on the auxiliary working end of the main body 1. Due to the difference in the shaft body, the thickness of the circuit board adapted by the buckle is also different. In keyboard DIY, the circuit board thickness 7 is currently mainly measured by a ruler, but the keyboard circuit board is usually a long board with a large area, which is not easy to operate during measurement. The width of each circuit board thickness measurement slot 7 is different. By snapping the circuit board in and making it fit completely, the thickness of the circuit board is equivalent to the width of the circuit board thickness measurement slot 7. The width value of each circuit board thickness measurement slot 7 is also engraved on the main body 1 for user viewing.

[0036] like Figure 8As shown, in this embodiment, two adjacent circuit board thickness detection slots 7 cooperate to form an axial stroke measurement baffle 71, and a stroke measurement hole 13 adapted to the key shaft core is provided on the side of the secondary working end of the main body 1. After the key shaft core passes through the stroke measurement hole 13, it is limitedly matched with the axial stroke measurement baffle 71. The stroke of the key shaft body is related to the shaft core length. The internal space size of the shaft body is usually in standard specifications. At this time, the longer the shaft core is, the shorter the movable stroke is, and the shorter the shaft core is, the longer the stroke that can be moved downward when pressed. The distance from the end of the stroke measurement hole 13 to the axial stroke measurement baffle 71 is a fixed value. By inserting the shaft core into the stroke measurement hole 13, it can be determined whether its shaft core length is the stroke length corresponding to this hole position.

[0037] like Figure 1 As shown, in this embodiment, both sides of the hinged part of the main body 1 adopt a hollow structure, thereby reducing the overall weight while ensuring the structural strength, so that it has sufficient stability and is light when used.

[0038] Embodiment 2:

[0039] like Figure 2 , Fig. 9 and Fig.10 As shown in the handle part, in this embodiment, the utility model includes a pair of main bodies 1 and a plurality of clamping assemblies 4 that are hingedly matched. The main working ends of the two main bodies 1 are provided with pressing protrusions 3 that cooperate with the button shaft mounting buckle 2. The secondary working ends of the main bodies 1 are provided with buckle disassembly blocks 11. The outer ends of the buckle disassembly blocks 11 are provided with guide slopes 12. When the two main bodies 1 are closed, the two buckle disassembly blocks 11 contact the connecting buckles 6 on both sides of the button shaft correspondingly, and the button shaft connecting buckles 6 are deformed outward along the guide slopes 12. The secondary working end of the main body 1 is the handle end of the main body 1. The button shaft is composed of a shaft core, a conductive metal sheet, an elastic member, a shaft cover and a base, wherein the shaft core, the conductive metal sheet and the elastic member are all encapsulated in the shaft cover and the base. The shaft core can move up and down in the shaft cover and the base, and the shaft cover and the base are fixed together by the button shaft connecting buckle 6. The shaft cover and the base need to be separated for lubrication and repair of the shaft core. The buckle disassembly block 11 is embedded in the inner side of the button shaft body connection buckle 6, and the button shaft body connection buckle 6 is deformed outward along the guide slope 12 by applying pressure, so that the limit of the shaft cover on the base can be released, and the shaft body can be opened. The overall structure is simple and the production cost is low.

[0040] Furthermore, different manufacturers use different buckles to connect the shaft cover and the base. The two mainstream shaft types on the market, Kailh shaft and Cherry shaft, use different buckles. In the present embodiment, there are three groups of buckle disassembly blocks 11. Two groups of buckle disassembly blocks 11 are arranged at intervals and the outer ends are located on one side of the main body 1. The remaining group of buckle disassembly blocks 11 is located between the other two groups of buckle disassembly blocks 11 and the outer ends are located on the other side of the main body 1. Among them, the two groups of buckle disassembly blocks 11 arranged at intervals can be used for the disassembly of Cherry shaft bodies, and the buckle disassembly block 11 that is arranged separately and located in the middle can be used for the disassembly of Kailh shaft bodies. This allows the present application to be compatible with the disassembly of two different shaft types, which can provide users with a more convenient use experience.

[0041] Embodiment three:

[0042] like Figure 2 , Fig. 9 and Fig.10 As shown, in this embodiment, the utility model comprises a pair of main bodies 1 and a plurality of pairs of clip assemblies 4 that are hingedly matched. The main working ends of the two main bodies 1 are both provided with pressing protrusions 3 that match with the button shaft mounting buckle 2. The main working ends of the main bodies 1 are also provided with a card slot 5, and the clip assembly 4 is detachably connected to the card slot 5. The secondary working end of the main body 1 is provided with a buckle disassembly block 11, and the outer end of the buckle disassembly block 11 is provided with a guide slope 12. When the two main bodies 1 are closed, the two buckle disassembly blocks 11 contact the connection buckles 6 on both sides of the button shaft, and the button shaft connection buckle 6 is deformed outward along the guide slope 12.

[0043] In this embodiment, a replaceable clamp assembly is combined to stably pull out the shaft body, and the clamp assembly for the key cap structure can also be compatible with the pull-out of the key cap, and the overall structure is compact and small. In addition, combined with the open shaft structure, the shaft body can be opened, which is convenient for users to maintain the shaft body.

[0044] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
