Description

Technical Field

[0001] The utility model relates to a desktop office auxiliary tool, in particular to a novel armrest. Background Art

[0002] Using a mouse to control a computer is a common way of working in modern times. In the process of operating a mouse, in addition to rotating, the human wrist also needs to translate in the vertical and horizontal directions, and the wrist rubs and slides on the desktop or mouse pad. Long-term use of a mouse can easily cause increased pressure in the carpal tunnel, leading to "carpal tunnel syndrome" (commonly known as mouse hand). The Chinese utility model patent with authorization announcement number CN2901417Y discloses a mobile mouse wrist rest, which includes a base pad layer, the upper surface of the base pad layer is covered with a lining layer, and a rolling member is provided at the bottom of the base pad layer. Although the mobile mouse wrist rest makes it convenient for the human wrist to press against the pad, and the pad rolls on the workbench with the movement of the arm, which improves the flexibility of mouse operation, it is still inconvenient for the wrist to swing left and right on the pad, and the structural design needs to be further improved. To this end, we propose a new type of hand support. Utility Model Content

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a novel hand support.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of hand support frame, including a base, a plurality of rollers are provided at the bottom of the base, a turntable is rotatably provided above the base, a hand support pad is provided at the turntable, a rotating assembly is provided between the turntable and the base, the rotating assembly includes an inner ring member and an outer ring member which can rotate relative to each other, the inner ring member and the outer ring member are fixedly connected to the base and the turntable respectively, and the turntable rotates relative to the base through the rotating assembly.

[0005] It is further explained that the base is provided with a middle tube portion for connecting with the inner ring component, and the middle tube portion is provided with an elastic undercut, and the elastic undercut buckles the upper end surface of the inner ring component to axially limit the inner ring component.

[0006] To further explain, the turntable is provided with a middle cylinder portion for connecting with the outer ring member, and a pressure foot portion for pressing against the upper end surface of the outer ring member is provided in the inner cavity of the middle cylinder portion.

[0007] To further explain, the rotating assembly also includes an intermediate component provided on the inner ring component and the outer ring component, and the intermediate component is provided with a plurality of balls rotatably arranged along the circumferential direction.

[0008] To further explain, a chassis is provided below the base, the roller is clamped between the chassis and the turntable, and a circular opening is provided at the chassis for exposing the roller.

[0009] To further explain, the material of the palm rest pad is silicone.

[0010] The beneficial effect of the utility model is that the utility model adopts a structural design combining a turntable and a base, and a rotating component is arranged between the turntable and the base. When the wrist is operating the mouse, the hand support pad on the turntable can swing left and right with the wrist, and the hand support frame can also move synchronously with the mouse, which can effectively relieve the shoulder pressure during long-term office work.

[0017] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Combined with Figure 1 To Attachment Figure 5As shown, a new type of hand support frame includes a base 10, a plurality of rollers 20 are arranged below the base 10, a turntable 30 is rotatably arranged above the base 10, and a hand support pad 31 is arranged on the turntable 30, and the material of the hand support pad 31 is silicone. A rotating assembly 40 is arranged between the turntable 30 and the base 10, and the rotating assembly 40 includes an inner ring 41 and an outer ring 42 that can rotate relative to each other. The inner ring 41 and the outer ring 42 are respectively fixedly connected to the base 10 and the turntable 30, and the turntable 30 rotates relative to the base 10 through the rotating assembly 40. When in use, the hand support frame is placed on the desktop, and the wrist is placed on the hand support pad 31. When the wrist is operating the mouse, the hand support pad 31 on the turntable 30 can swing left and right with the wrist.

[0019] Combined with Figure 1 , Attachment Figure 4 and attached Figure 5 As shown, the base 10 is provided with a middle tube portion 11 for connecting with the inner ring member 41, and an elastic undercut 12 is provided at the middle tube portion 11. Figure 4 As shown, the elastic undercut 12 buckles the upper end surface of the inner ring 41 to axially limit the inner ring 41. The turntable 30 is provided with a middle cylinder 32 for connecting with the outer ring 42, and a presser foot 33 for pressing the upper end surface of the outer ring 42 is provided in the inner cavity of the middle cylinder 32.

[0020] Combined with Figure 4 and attached Figure 5 As shown, the rotating assembly 40 also includes an intermediate component 43 provided between the inner ring component 41 and the outer ring component 42, and the intermediate component 43 is provided with a plurality of balls 431 rotatably arranged along the circumferential direction. When installing, the rotating assembly 40 is first installed at the middle tube portion 11 of the base 10, and the elastic undercut 12 at the middle tube portion 11 buckles the upper end surface of the inner ring component 41, so that the inner ring component 41 of the rotating assembly 40 does not move axially, and then the turntable 30 is installed above the base 10. The rotating assembly 40 can be specifically replaced by other conventional components such as bearings.

[0021] As attached Figure 5 As shown, a chassis 50 is provided below the base 10, and the roller 20 is sandwiched between the chassis 50 and the turntable 30. A circular opening 51 is provided at the chassis 50 for exposing the roller 20. When in use, the hand support is placed on the desktop, and the wrist is placed on the hand support pad 31. When the hand drives the mouse to move, the roller 20 below the hand support can make the hand support move synchronously with the mouse.
