Description

Wrist-protecting keyboard hand support

Technical Field

The utility model relates to a computer accessories field, concretely relates to wrist band keyboard hand rest.

Background

The wrist-protecting keyboard hand support is used for effectively protecting the wrist by placing the wrist on the keyboard support when a user uses the keyboard, the wrist is prevented from being directly contacted with a desktop of a hard nation, better comfort is obtained, the wrist is raised to a height as high as that of the keyboard, the palm does not need to incline upwards during typing, the wrist-protecting keyboard hand support is not easy to fatigue, and the keyboard using time can be longer. The keyboard support in the existing market has the following defects that firstly, the upper surface of the existing keyboard support is provided with a layer of foamed cotton, which is rough and not smooth, and the wrist directly contacts the keyboard support to feel common; secondly, the foam cotton has relatively poor rebound resilience, is easy to deform and difficult to recover after being pressed for a long time, and has secondary use effect; thirdly, four-side stitching is easy to separate lines, so that the layers are separated.

SUMMERY OF THE UTILITY MODEL

To the technical problem such as contact that prior art keyboard tray exists is felt generally, the resilience is relatively poor, the utility model provides a wrist band keyboard hand rest, concrete technical scheme is as follows:

a wrist-protecting keyboard hand support comprises a Lycra fabric layer, a memory cotton layer, a gray cardboard layer and a composite styrene-butadiene rubber layer, wherein the upper surface of the Lycra fabric layer is exposed to be in contact with the wrist of a person, the memory cotton layer is coated on the inner side of the Lycra fabric layer, four sides of the Lycra fabric layer are sewn with four sides of the composite styrene-butadiene rubber layer, the gray cardboard layer is located between the memory cotton layer and the composite styrene-butadiene rubber layer, and the gray cardboard layer bears the memory cotton layer.

As an optimal scheme of the utility model, compound butylbenzene rubber layer includes non-woven fabrics layer and butylbenzene rubber layer, non-woven fabrics layer lockstitching a border and laminating butylbenzene rubber layer.

As an optimal scheme of the utility model, butadiene styrene rubber layer bottom is equipped with a plurality of non-slip raised.

As a preferred scheme of the utility model, the upper surface printing of lycra precoat has decorative pattern.

The utility model has the advantages that: the human wrist contacts with lycra surface fabric layer upper surface, the lycra surface fabric has very good travelling comfort, can obtain fine feeling and do not harm skin, and the cotton layer of memory has stickness and elastic characteristic concurrently, absorb impact kinetic energy and can use repeatedly and be unlikely to permanent deformation, guarantee to use more permanently, it is more durable, can effectively alleviate the wrist pain, the red swelling that the official working arouses because of typing for a long time, protection wrist joint, the prevention keyboard hand, in addition, lycra surface fabric layer upper surface printing has decorative pattern, more pleasing to the eye attracts the consumer, satisfy the consumer demand.

fig. 2 is an enlarged view at a in fig. 1.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

As shown in figure 1, the wrist-protecting keyboard hand support comprises a Lycra fabric layer 1, a memory cotton layer 2, a gray card paper board layer 3 and a composite styrene-butadiene rubber layer 4, wherein the upper surface of the Lycra fabric layer 1 is exposed to be contacted with the wrist of a person, the memory cotton layer 2 covers the inner side of the Lycra fabric layer 1, four sides of the composite styrene-butadiene rubber layer 4 are sewn on four sides of the Lycra fabric layer 1, the gray card paper board layer 3 is located between the memory cotton layer 2 and the composite styrene-butadiene rubber layer 4, the memory cotton layer 2 is borne by the gray card paper board layer 3, the Lycra fabric layer 1 can be directly contacted with the skin and does not hurt the skin, and the wrist-protecting keyboard; the upper part of the memory cotton layer 2 can sense the temperature of the human body, is gradually softened, absorbs the pressure of the human body to adjust the human body to the most comfortable posture state, and still maintains sufficient supporting force for the part of the lower part which is not contacted with the temperature of the human body, has the capability of slow deformation, and can slowly recover the original shape for repeated use without permanent deformation after being deformed by external force; the gray cardboard layer 3 provides certain hardness, so that the keyboard support can support the memory cotton layer 2 more smoothly.

Specifically, the composite styrene-butadiene rubber layer 4 comprises a non-woven fabric layer 41 and a styrene-butadiene rubber layer 42, the non-woven fabric layer 41 is in lockstitching with the styrene-butadiene rubber layer 42 and is not prone to off-line, the styrene-butadiene rubber layer 42 has the characteristics of shock resistance, heat preservation, elasticity, impermeability, air impermeability and the like, the internal memory cotton layer 2 and the internal gray cardboard layer 3 are effectively protected, a plurality of anti-skid protrusions are arranged at the bottom of the styrene-butadiene rubber layer 42 and can prevent skidding, so that the keyboard hand support cannot easily slide on a desktop, and more convenience is brought.

Specifically, the decorative patterns are printed on the upper surface of the Lycra fabric layer 1, so that the printing effect is outstanding, and the Lycra fabric layer is more attractive to consumers.
