The keyboard bracket arranged on the armrests of a chair comprises a fixing clip, a connecting arm and a pallet support which are fixed on a chair, wherein the fixing clip and the connecting arm are connected via a hollow over-half spherical structure while a coccid form of a bearing rod is arranged on the fixing clip, the bearing rod is plugged into the cylinder of the connecting rod to be fixed via screws. The keyboard bracket arranged on the armrests of a chair has simple use, and adjustable extension and direction.

Description

Be installed in the keyboard drawer on the armrests

Technical field

The utility model relates to a kind of keyboard drawer, specifically relates to a kind of keyboard drawer that is installed on the armrests.

Background technology

The computernik works before computer all day, and is arduous tired, all day operation keyboard, the sensation that arm has acid, heat, rises; Reduce labor intensity, creating good working environment is the direction that people make great efforts, and the measure of many improvement is arranged, yet also keyboard tray is not placed on the product on the armrests.

Summary of the invention

It is a kind of practical and convenient that the purpose of this utility model is to provide, and makes the keyboard drawer on the armrests of being installed in of the tired hand of computer operation person.

The purpose of this utility model is to realize like this; Be installed in keyboard drawer on the armrests and include that the geometrical clamp, linking arm and the tray rack that are fixed on the chair form; Linking arm is made up of bearing rod, connecting rod;

Also have a circular folder below geometrical clamp, described circular folder is that inside has clip sawtooth pattern, screw B sealing, and locating hole is arranged on clip, and geometrical clamp is connected surely with circular clamping; Bearing rod insert with the connecting rod cylinder in lead to and connect, screw is fixed; Geometrical clamp and linking arm are connected by the hollow most spherical structures that the spherical of bearing rod is installed in geometrical clamp.One of the close geometrical clamp of described bearing rod is a spherical, described spherical is big or small the same with the sphere in the middle of the geometrical clamp, the other end of bearing rod has 3-7 row to run through the hole of bearing rod side, described connecting rod is " factory " font, an end that is connected with bearing rod is columnar, on have 3-7 row to run through the hole of bearing rod side; The other end of connecting rod is connected with keyboard drawer, and described keyboard drawer is the reeded plate of the support of keyboard and mouse, and the bottom is provided with reinforcement.

The utility model is owing to taked above structure, and it is easy to use that the keyboard drawer that is installed on the armrests is had, and flexible and direction can be regulated, and can satisfy people's needs.
