Description

Technical Field

[0001] This utility model relates to the field of wrist support technology, and in particular to a wrist support. Background Technology

[0002] When using a computer, the mouse is a commonly used input device. When users operate the mouse for a long time, their wrists are constantly suspended or in an unnatural bent position, which can easily lead to wrist muscle fatigue, soreness, and even occupational diseases such as carpal tunnel syndrome. Therefore, wrist supports have emerged as an auxiliary tool. Their main function is to provide support for the wrist, relieve wrist pressure, and improve operating comfort. However, wrist supports currently on the market still have many shortcomings: First, most wrist supports are designed to be placed directly on the table, lacking a stable fixed structure. During use, they are prone to sliding with arm movements, which not only affects the continuity of operation, but may also cause wrist support failure due to positional displacement, exacerbating fatigue. Second, the angle of existing wrist supports is mostly fixed and cannot be adjusted according to the user's operating habits, sitting posture, or natural arm tilt angle. Since different users have different arm positions (such as the degree of elbow flare, wrist flexion angle, etc.), wrist supports with fixed angles are difficult to precisely fit the physiological curve of the arm, often resulting in local pressure or insufficient support, which greatly reduces comfort and may still cause wrist discomfort with long-term use. Therefore, it is necessary to provide a new wrist support to solve the above-mentioned technical problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a wrist support pad.

[0004] The wrist support provided by this utility model includes: a mounting base, a support body for supporting the wrist mounted on the top of the mounting base, a connecting base fixedly connected to one side of the mounting base, a clamping base fixedly connected to one side of the connecting base, clamping blocks symmetrically mounted on the top of the clamping base, a driving component for driving the clamping blocks to move installed inside the clamping base and the connecting base, and a rotating component for driving the support body to rotate installed inside the mounting base and the connecting base.

[0005] Preferably, the driving assembly includes: a first rotating column, a bidirectional threaded rod, a threaded block, and a connecting rod. The first rotating column is rotatably connected inside the connecting seat, and the bidirectional threaded rod is rotatably connected to one side of the connecting seat. One end of the first rotating column is fixedly connected to the bidirectional threaded rod. A sliding groove is provided inside the clamping seat, and threaded blocks are symmetrically slidably connected to the clamping seat inside the sliding groove. Both threaded blocks are threadedly connected to the bidirectional threaded rod, and both ends of the two threaded blocks are symmetrically rotatably connected to connecting rods. Multiple sets of connecting rods are rotatably connected to corresponding clamping blocks.

[0006] Preferably, the rotating assembly includes: a second rotating column, a rotating rod, a worm gear, a worm wheel, and a turntable. The second rotating column is rotatably connected inside the connecting seat, and the rotating rod is rotatably connected inside the mounting seat. One end of the second rotating column is fixedly connected to the rotating rod, and the worm gear is fixedly connected to the outer wall of the rotating rod. The worm wheel is rotatably connected inside the mounting seat, and the worm wheel meshes with the worm gear. The turntable is fixedly connected to the top of the worm wheel, and the top of the turntable is fixedly connected to the support body.

[0007] Preferably, an internal spline is provided at one end of both the first rotating column and the second rotating column.

[0008] Preferably, the connecting seat has a rotating handle on one side, and an external spline is provided at one end of the rotating handle, with the internal spline cooperating with the external spline.

[0009] Preferably, the bidirectional threaded rod is located inside the slide groove, and the axis of the bidirectional threaded rod is on the same straight line as the central axis of the slide groove.

[0010] Preferably, the top of the support body is designed with an arc shape.

[0011] Preferably, a rubber pad is fixedly connected to the top of each of the two clamping blocks.

[0012] Compared with related technologies, the wrist support pad provided by this utility model has the following beneficial effects: 1. Improve fixed stability This device achieves stable fixation to the desktop through a drive component. The connecting rod pushes the clamping block up and presses against the bottom of the desktop. In conjunction with the rubber pad on the top of the clamping block, it can increase friction to prevent the pad from slipping and avoid damage to the desktop. This fixing method is suitable for desktops of different thicknesses, ensuring that the pad is always in the ideal position during the user's mouse operation, continuously providing effective support for the wrist and reducing fatigue.

[0013] 2. Enhanced angle adaptability With the help of a rotating component, the support pad can be rotated flexibly to adjust the angle. The groove on the top surface of the support pad can be precisely adapted to the user's operating habits, sitting posture or the natural tilt angle of the arm, ensuring that the groove fits closely with the physiological curve under the arm, which significantly improves the comfort of use, reduces the risk of wrist discomfort caused by long-term use, and better protects the user's wrist health.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 4 A wrist support pad includes a mounting base 2, a support body 3 for supporting the wrist is mounted on the top of the mounting base 2, a connecting base 4 is fixedly connected to one side of the mounting base 2, a clamping base 5 is fixedly connected to one side of the connecting base 4, clamping blocks 6 are symmetrically mounted on the top of the clamping base 5, a driving component for moving the clamping blocks 6 is installed inside the clamping base 5 and the connecting base 4, and a rotating component for rotating the support body 3 is installed inside the mounting base 2 and the connecting base 4. The top of the support body 3 is arc-shaped, and rubber pads are fixedly connected to the tops of the two clamping blocks 6.

[0019] It should be noted that the curved design at the top of the support body 3 adapts to the shape of the customer's wrist, providing continuous and effective support for the wrist.

[0020] Please see Figures 1 to 4 The driving assembly includes: a first rotating column 21, a bidirectional threaded rod 22, a threaded block 23, and a connecting rod 24. The first rotating column 21 is rotatably connected inside the connecting seat 4, and the bidirectional threaded rod 22 is rotatably connected to one side of the connecting seat 4. One end of the first rotating column 21 is fixedly connected to the bidirectional threaded rod 22. A sliding groove is provided inside the clamping seat 5. Threaded blocks 23 are symmetrically slidably connected inside the clamping seat 5 in the sliding groove. Both threaded blocks 23 are threadedly connected to the bidirectional threaded rod 22. Connecting rods 24 are symmetrically rotatably connected to both ends of the two threaded blocks 23. Multiple sets of connecting rods 24 are rotatably connected to corresponding clamping blocks 6. The bidirectional threaded rod 22 is located inside the sliding groove, and the axis of the bidirectional threaded rod 22 is on the same straight line as the central axis of the sliding groove.

[0021] It should be noted that the two clamping blocks 6 are initially in contact with each other, and are then squeezed by the connecting rod 24, causing the two clamping blocks 6 to approach the bottom of the tabletop 1 until they are stably squeezed.

[0022] Please see Figure 1 and Figure 4 The rotating assembly includes: a second rotating column 31, a rotating rod 32, a worm gear 33, a worm wheel 34, and a turntable 35. The second rotating column 31 is rotatably connected inside the connecting seat 4, and the rotating rod 32 is rotatably connected inside the mounting seat 2. One end of the second rotating column 31 is fixedly connected to the rotating rod 32, and the worm gear 33 is fixedly connected to the outer wall of the rotating rod 32. The worm wheel 34 is rotatably connected inside the mounting seat 2, and the worm wheel 34 meshes with the worm gear 33. The top of the worm wheel 34 is fixedly connected to the turntable 35, and the top of the turntable 35 is fixedly connected to the support body 3. One end of the first rotating column 21 and the second rotating column 31 are both provided with an internal spline 41. A rotating handle 51 is provided on one side of the connecting seat 4, and one end of the rotating handle 51 is provided with an external spline 52. The internal spline 41 and the external spline 52 cooperate with each other.

[0023] It should be noted that a turntable 35 is fixedly connected to the top of the worm gear 34. The turntable 35 is fixed to the pad body 3, so the rotation of the worm gear 34 will cause the turntable 35 and the pad body 3 to rotate together.

[0024] The working principle of the wrist support pad provided by this utility model is as follows: Desktop 1 is the supporting base of the entire device, providing an installation platform for other components. Mounting base 2 has a support body 3 installed on top, which is the direct support structure for the support body 3. As the core component, the main function of the support body 3 is to support the user's wrist, reduce wrist pressure when using the mouse, and improve user comfort.

[0025] Mounting bracket 2 is fixed: Place the mounting base 2 on the tabletop 1, with the tabletop 1 positioned between the mounting base 2 and the clamping base 5. Insert the rotating handle 51 into the first rotating column 21. The rotating handle 51 engages with the inner spline 41 of the first rotating column 21 via the outer spline 52, causing the first rotating column 21 to rotate. The first rotating column 21 is fixedly connected to the bidirectional threaded rod 22, thereby causing the bidirectional threaded rod 22 to rotate. Since the bidirectional threaded rod 22 is threadedly connected to two threaded blocks 23, and the threaded blocks 23 slide within the groove of the clamping base 5, when the bidirectional threaded rod 22 rotates, the two threaded blocks 23 will move towards each other along the groove. The threaded blocks 23 are rotatably connected to the clamping block 6 via the connecting rod 24, thereby pushing or pulling the clamping block 6 upward, causing the clamping block 6 to press against the bottom surface of the tabletop 1. When the clamping block 6 presses against the tabletop 1, the wrist rest can be fixed on the tabletop 1. The rubber pad increases friction, making the fixation more secure, while avoiding damage to the tabletop 1.

[0026] Pad body 3 adjustment: The rotating component enables the pad body 3 to rotate. By adjusting the angle of the pad body 3, the groove on the top surface of the pad body 3 can be precisely adapted to the tilt of the arm, thereby improving the fit and comfort during use. The rotating handle 51 engages with the inner spline 41 of the second rotating column 31. Rotating the handle 51 can drive the second rotating column 31 to rotate. The second rotating column 31 is fixedly connected to the rotating rod 32, which in turn drives the rotating rod 32 to rotate. The worm 33 on the outer wall of the rotating rod 32 meshes with the worm wheel 34. When the worm 33 rotates, it drives the worm wheel 34 to rotate. A turntable 35 is fixedly connected to the top of the worm wheel 34. The turntable 35 is fixed to the pad body 3, so the rotation of the worm wheel 34 will cause the turntable 35 and the pad body 3 to rotate together. Thus, the angle of the pad body 3 can be adjusted according to the user's operating habits and posture, providing more comfortable support for the wrist.
