Description

Foldable external keyboard placer

Technical Field

The utility model relates to a peripheral hardware field especially relates to a foldable external keyboard placer.

Background

With the progress and development of science and technology, more and more work needs to be completed through computers and networks, more and more people need to work for a long time on desk, and therefore, a plurality of computer peripherals which tend to be convenient or comfortable are derived. The keyboard is an indispensable peripheral component, but the keyboard bracket is single in form at present, and under the condition of emphasizing comfortable office work, if a lot of design works are office work in lying posture, the existing keyboard bracket cannot play an auxiliary role.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art weak point, provide a simple structure, convenient to use's a foldable external keyboard placer.

The equipment comprises a fixing part, wherein the fixing part can be fixed on a front blocking edge of an office table or an original keyboard bracket, and plays a role in stably supporting the whole equipment.

A first connecting rod is fixedly arranged at the rear end of the fixing part, and a first ball bearing is arranged at the tail end of the first connecting rod;

a second connecting rod is fixedly arranged on the first ball bearing, and a second ball bearing is arranged at the tail end of the second connecting rod;

and a third connecting rod is fixedly arranged on the second ball bearing, and a keyboard bracket is fixedly arranged at the tail end of the third connecting rod.

Furthermore, the fixing part is in a claw form, and the claw is fixed on the computer desk through hard limiting of a bolt;

the number of the clamping jaws is two.

Furthermore, the first connecting rod, the first ball bearing, the second connecting rod, the second ball bearing and the third connecting rod are respectively provided with two sets, and the two sets of first connecting rods are respectively and fixedly arranged at the end positions of the two clamping jaws.

Furthermore, a linkage rod is hinged between the second connecting rods;

the third link is in the form of a bushing.

Further, the keyboard bracket comprises a bottom plate and a baffle plate which is arranged upwards and integrally extends from the edge of the bottom plate, and limiting baffle cards are arranged on the baffle plates on two opposite sides in a sliding mode and are elastically connected with the upper baffle plate through springs.

Furthermore, the ball bearing is a self-locking ball bearing.

The utility model has the advantages that: the utility model discloses simple structure, convenient to use, low in cost and easy to maintain have solved the form singleness that current keyboard tray exists through simple structure, can't use the keyboard of the gesture of lying, play the problem of auxiliary action. Through the linkage of the multistage connecting rods and the ball bearings, the keyboard can be unfolded and the angle and the position can be flexibly adjusted.
