Description

Technical Field

[0001] This utility model belongs to the field of keyboard technology, and in particular relates to a mechanical keyboard that is easy to adjust in height. Background Technology

[0002] In today's era of deep integration between information technology and office peripherals, mechanical keyboards, with their unique key feel, durability, and customizability, are widely used in diverse scenarios such as office work, e-sports, and programming. With the increasing popularity of ergonomic principles, whether the keyboard height adapts to the natural curvature of the user's wrist while seated has become a key factor affecting user experience and health. Prolonged use of an uncomfortable keyboard height can easily lead to carpal tunnel syndrome, neck and shoulder fatigue, etc. Therefore, height adjustability has become an important requirement for frequent users.

[0003] Currently, mechanical keyboard height adjustment solutions on the market have significant technical shortcomings. Traditional adjustment structures have limited functionality, and most products rely on foldable feet to achieve fixed-level adjustment, which can only provide limited height variations and cannot meet the personalized needs of different users for keyboard tilt angle and vertical height.

[0004] To address this issue, we offer a height-adjustable mechanical keyboard. Utility Model Content

[0005] The purpose of this invention is to provide a mechanical keyboard that is easy to adjust in height. By combining the height adjustment component and the fixing component, it solves the problem that existing mechanical keyboards rely on foldable feet to achieve fixed-level adjustment, which can only provide limited height changes and cannot meet the personalized needs of different users for keyboard tilt angle and vertical height.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a height-adjustable mechanical keyboard, comprising a mechanical keyboard body, a height adjustment component movably connected to the bottom of the mechanical keyboard body, a fixing component fixedly connected to the inner cavity of the height adjustment component, and the height adjustment component including sliding grooves formed at the front and rear ends of both sides of the mechanical keyboard body. Positioning holes are formed on both sides of the inner cavity of the sliding grooves. A connecting plate is slidably connected to the inner cavity of the sliding grooves, and mounting holes are formed on both sides of the connecting plate. A spring is fixedly connected to the inner cavity of the mounting hole, and a connecting post is fixedly connected to the other end of the spring. The other end of the connecting column extends into the inner cavity of the positioning hole. A support base is fixedly connected to the bottom of the connecting plate. The fixing assembly includes a mounting groove formed in the inner cavity of the connecting plate. The mounting groove communicates with the mounting hole. A lead screw is fixedly connected to the inner cavity of the mounting groove through a bearing. The threads at both ends of the lead screw are designed in opposite directions. Both ends of the lead screw pass through the inner cavity of the mounting hole and are threadedly connected to a limit tube. A worm gear is fixedly connected to one end of the lead screw located in the inner cavity of the mounting groove. A worm is engaged at the bottom of the worm gear. One end of the worm is fixedly connected to the inner wall of the mounting groove through a bearing.

[0008] The present invention is further configured such that there are five positioning holes, which are evenly distributed vertically. The bottom of the top positioning hole, the top of the bottom positioning hole, and the outer edges of the other positioning holes are all rounded. This design enables the keyboard height to be adjusted evenly in multiple levels. Users can flexibly switch between different height levels according to their own needs, meeting diverse ergonomic adaptation requirements. The rounded corners can effectively reduce the resistance when the connecting post is inserted into the positioning hole, making the adjustment process smoother and more stable, avoiding jamming or wear problems caused by rigid contact, and improving the comfort and reliability of the height adjustment operation.

[0009] The present invention is further configured such that the inner wall of the positioning hole and the end of the connecting column away from the spring are both spherical. The spherical contact surface can increase the contact area between the two, so that the stress generated during the adjustment process can be evenly distributed, avoiding the wear or deformation of the components caused by excessive local force, thereby extending the service life of the positioning structure. The spherical design reduces the frictional resistance during contact, and together with the elastic thrust of the spring, it can realize the quick engagement and disengagement of the connecting column and the positioning hole, further improving the convenience of height adjustment.

[0010] The present invention is further configured such that grooves are provided at both ends of the bottom side of the support base, and a support foot 1 is movably connected to the inner cavity of the groove via a pin. A support foot 2 is fitted on the surface of the support foot 1. This combined structure allows the support foot 1 to rotate and unfold to a suitable angle around the pin, forming a retractable triangular support structure with the support foot 2. This effectively expands the support area of ​​the bottom of the keyboard, enhances lateral stability, and can keep the keyboard stable even when used on uneven desktops or in tilted environments, adapting to a variety of complex usage scenarios.

[0011] The present invention is further configured such that rubber pads are fixedly connected to the four corners of the bottom of the support base, and the bottom of the rubber pads is provided with anti-slip texture. The elastic material of the rubber pads can increase the contact friction between the keyboard and the desktop, and the anti-slip texture further enhances this effect. It can effectively prevent the keyboard from shifting or sliding due to hand force during typing, improve the safety and stability during use, and is especially suitable for scenarios that require the keyboard to be fixed in place, such as high-frequency typing or e-sports operation.

[0012] The present invention is further configured such that limiting grooves are provided at the top and bottom of the limiting tube, and a limiting strip is slidably connected to the inner cavity of the limiting groove. The other side of the limiting strip is fixedly connected to the inner wall of the mounting groove. This structure restricts the circumferential movement of the limiting tube when the lead screw rotates through the sliding cooperation between the limiting strip and the limiting groove, ensuring that the rotational force of the lead screw can be completely converted into the axial displacement of the limiting tube, thereby accurately squeezing or releasing the spring, realizing effective control of the clamping force between the connecting column and the positioning hole, and improving the reliability and stability of the locking process of the fixing component.

[0013] The present invention is further configured such that the other end of the worm gear extends through the outside of the connecting plate and is fixedly connected to a handwheel. The handwheel provides users with an intuitive and easy-to-use operating interface. Without the need for additional tools, users can drive the worm gear to rotate simply by manually rotating the handwheel. This, in turn, enables the rotation of the lead screw and the movement of the limit tube through the worm gear transmission mechanism. This simplifies the height adjustment process, reduces the difficulty of adjustment, and significantly improves the human-computer interaction experience, allowing different users to easily and accurately adjust and lock the keyboard height.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model achieves precise adjustment and stable locking of keyboard height through the synergistic effect of the height adjustment component and the fixing component. Users can achieve multiple height adjustments by sliding the connecting plate in the slide groove. The spring-driven connecting column is embedded in the positioning hole at different positions to complete the initial fixation. Further rotation of the handwheel drives the worm gear and worm wheel transmission, causing the lead screw to drive the limit tube to move and squeeze the spring, enhancing the clamping force between the connecting column and the positioning hole, forming a double locking mechanism. This design retains the convenience of traditional foot adjustment while improving the locking reliability through mechanical transmission, solving the problems of limited adjustment levels and easy loosening of the lock in the existing technology, and adapting to the personalized height needs of different users in office, e-sports and other scenarios.

[0016] 2. The combined structure of support foot one and support foot two at the bottom of the support base of this utility model can be rotated and unfolded to form a triangular support, expanding the support area and enhancing lateral stability. The rubber pad and anti-slip texture design further enhance the friction between the keyboard and the desktop, preventing displacement during use. The rounded corners of the positioning hole edges and the spherical contact surface design between the connecting post and the positioning hole reduce the locking resistance while ensuring uniform force distribution and extending service life. The limiting tube, through the sliding cooperation of the limiting groove and the limiting strip, ensures that the rotational force of the screw is effectively converted into axial displacement, improving the reliability of the locking structure. The handwheel design at the end of the worm gear provides an easy-to-operate force application point, reducing the difficulty of adjustment. The overall structural improvement effectively solves the usage problems caused by the traditional adjustment keyboard due to center of gravity offset, insufficient support, or inconvenient operation, significantly improving the human-computer interaction experience.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-6 This utility model relates to a height-adjustable mechanical keyboard, comprising a mechanical keyboard body 1, a height adjustment component 2 movably connected to the bottom of the mechanical keyboard body 1, a fixing component 3 fixedly connected to the inner cavity of the height adjustment component 2, and the height adjustment component 2 including sliding grooves 21 at both ends of the mechanical keyboard body 1, positioning holes 22 on both sides of the inner cavity of the sliding grooves 21, a connecting plate 23 slidably connected to the inner cavity of the sliding grooves 21, mounting holes 24 on both sides of the connecting plate 23, a spring 25 fixedly connected to the inner cavity of the mounting holes 24, and a connecting post 26 fixedly connected to the other end of the spring 25. One end extends into the inner cavity of the positioning hole 22. A support base 27 is fixedly connected to the bottom of the connecting plate 23. The fixing component 3 includes a mounting groove 31 opened in the inner cavity of the connecting plate 23. The mounting groove 31 communicates with the mounting hole 24. A lead screw 32 is fixedly connected to the inner cavity of the mounting groove 31 through a bearing. The threads at both ends of the lead screw 32 are designed to be opposite. Both ends of the lead screw 32 pass through the inner cavity of the mounting hole 24 and are threadedly connected to a limit tube 33. A worm gear 34 is fixedly connected to one end of the lead screw 32 located in the inner cavity of the mounting groove 31. A worm 35 is meshed at the bottom of the worm gear 34. One end of the worm 35 is fixedly connected to the inner wall of the mounting groove 31 through a bearing.

[0028] Specifically: the inner wall of the slide groove 21 has equidistantly distributed positioning holes 22. The inner wall of the positioning holes 22 and the end of the connecting column 26 are both spherically designed to reduce contact stress. The mounting hole 24 has a built-in spring 25 and a connecting column 26. Under normal conditions, the spring 25 pushes the connecting column 26 into the positioning hole 22 to form a snap-fit. The groove 28 is hinged to the first support foot 29 by a pin. The first support foot 29 can rotate around the pin to unfold or retract. The second support foot 210 on the surface can extend and retract axially to adjust the support length. The worm gear 34 is fixed in the middle of the lead screw 32 and meshes with the bottom worm 35 to form a vertical transmission. Rotating the worm 35 can drive the lead screw 32 to rotate synchronously. The limiting tube 33 slides with the limiting strip 37 on the inner wall of the mounting groove 31 through the limiting grooves 36 at the top and bottom, ensuring that it can only move axially and does not rotate with the lead screw 32, thereby realizing the compression or release of the spring 25.

[0029] Example 2

[0030] Please see Figure 1-6Based on Embodiment 1, there are five positioning holes 22, which are distributed at equal distances. The bottom of the top positioning hole 22, the top of the bottom positioning hole 22, and the outer edges of the other positioning holes 22 are all rounded. The inner wall of the positioning hole 22 and the end of the connecting column 26 away from the spring 25 are all spherical. The left and right ends of the bottom side of the support base 27 are provided with grooves 28. The inner cavity of the groove 28 is movably connected to the first support foot 29 by a pin. The surface of the first support foot 29 is fitted with the second support foot 210. The four corners of the bottom of the support base 27 are fixedly connected with rubber pads 211. The bottom of the rubber pads 211 is provided with anti-slip texture. The top and bottom of the limiting tube 33 are provided with limiting grooves 36. The inner cavity of the limiting groove 36 is slidably connected to the limiting strip 37. The other side of the limiting strip 37 is fixedly connected to the inner wall of the mounting groove 31. The other end of the worm gear 35 extends to the outside of the connecting plate 23 and is fixedly connected to a handwheel.

[0031] Specifically: This design enables multi-level uniform adjustment of the keyboard height, allowing users to flexibly switch between different height levels according to their needs, meeting diverse ergonomic adaptation requirements. The rounded corners effectively reduce resistance when the connecting post 26 engages with the positioning hole 22, making the adjustment process smoother and more stable, avoiding jamming or wear caused by rigid contact, and improving the comfort and reliability of height adjustment operation. The spherical contact surface increases the contact area between the two, allowing stress generated during adjustment to be evenly distributed, avoiding excessive localized force that could cause component wear or deformation, thereby extending the service life of the positioning structure. The spherical design reduces frictional resistance during contact, and combined with the elastic thrust of the spring 25, it enables quick engagement and disengagement of the connecting post 26 and the positioning hole 22, further enhancing the convenience of height adjustment. This combined structure allows support foot 1 29 to rotate and unfold to a suitable angle around the pivot, forming a retractable triangular support structure with support foot 2 210, effectively expanding the support area at the bottom of the keyboard and enhancing lateral stability. Even when used on uneven desktops or in tilted environments, it can maintain the keyboard's stable placement, adapting to various complex usage scenarios. Rubber pad 2 The elastic material of the 11 increases the contact friction between the keyboard and the desktop, and the anti-slip texture further enhances this effect. It can effectively prevent the keyboard from shifting or sliding due to hand force during typing, improving safety and stability during use. It is especially suitable for scenarios where the keyboard needs to be stationary, such as high-frequency typing or e-sports operations. This structure restricts the circumferential movement of the limiting tube 33 when the lead screw 32 rotates through the sliding cooperation of the limiting strip 37 and the limiting groove 36. This ensures that the rotational force of the lead screw 32 can be completely converted into the axial displacement of the limiting tube 33, thereby accurately squeezing or releasing the elastic material. Spring 25 effectively controls the clamping force between the connecting post 26 and the positioning hole 22, improving the reliability and stability of the locking process of the fixing component 3. The handwheel provides users with an intuitive and easy-to-use operating interface. Without the need for additional tools, simply rotating the handwheel manually drives the worm gear 35 to rotate, which in turn realizes the rotation of the lead screw 32 and the movement of the limit tube 33 through the worm wheel 34 and worm gear 35 transmission mechanism. This simplifies the height adjustment operation process, reduces the adjustment difficulty, and significantly improves the human-computer interaction experience, allowing different users to easily and accurately adjust and lock the keyboard height.

[0032] The working principle of this utility model is as follows: The support base 27 is pulled downwards, causing the connecting column 26 to overcome the spring force of the spring 25 and exit from the current positioning hole 22. After sliding along the slide groove 21 to the target height, the spring 25 pushes the connecting column 26 into the corresponding positioning hole 22, completing the initial positioning. Then, the handwheel is rotated to drive the worm gear 35 to rotate, which in turn drives the lead screw 32 to rotate synchronously through the worm wheel 34. This drives the limit tubes 33 on both sides to move towards the connecting column 26 and press the connecting column 26, increasing the contact pressure between the connecting column 26 and the positioning hole 22, thus achieving secondary locking. The support foot 29 at the bottom of the support base 27 is unfolded to a suitable angle. If necessary, the support foot 210 is stretched to adapt to uneven desktops. The rubber pad 211 and anti-slip texture ensure overall stability. When the height needs to be lowered, the handwheel is rotated in the opposite direction to contact the limit of the connecting column 26, and the keyboard body is pressed upwards to move the connecting plate 23 to the lower positioning hole 22. The above locking steps are repeated to complete the height adjustment.

[0033] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
