Abstract
The utility model provides a device for installing keyboard tray, includes girder, slide rail, girder fixing bolt and fixing bolt roof. The horizontal component that the girder passes through girder upper portion hangs on the desktop, screw in in the screw thread through -hole of girder fixing bolt follow girder bottom to screw out from the screw thread through -hole other end, partial screw in that the bolt was screwed out is to the screw hole of fixing bolt roof lower part in. Girder fixing bolt makes progress the precession and pushes up desktop bottom until the fixing bolt roof, and the horizontal component on fixing bolt roof and girder upper portion cliies the desktop, realizes fixing of girder. The side of girder is installed to the slide rail, and the slider of slide rail can be used to install keyboard tray. The utility model discloses the required work load of installation keyboard tray has been reduced, the desk can be do not not harmd moreover.
Description
Technical field
The utility model belongs to the parts of furniture computer desk (containing desk, desk), particularly for the device of fitting key plate rail.
Background technology
Along with popularizing of computer, a lot of people needs operating computer for a long time to carry out work or amusement.Normally be positioned on desktop by keyboard and mouse, the height of such keyboard and mouse is too high for the user, and cannot regulate height.Long-Time Service can make the muscular tone of wrist, elbow, shoulder, neck position, causes discomfort or even disease.The keyboard frame of adjustable-height on sale on the market and angle at present, this keyboard frame can be adjusted to the height making user comfortable, and its problem is to install inconvenience.This keyboard frame needs to be screwed bottom desktop, installs very inconvenient, and can damage bottom desk, if allowable damage desk just cannot not installed.
Summary of the invention
The utility model, in order to overcome the deficiency of current keyboard frame in installation, provides a kind of easy for installation and do not damage the device for fitting key plate rail of desk.
The utility model solves the technical scheme that its technical problem uses: with crossbeam, crossbeam set bolt and set bolt top board clamping desk.During use, crossbeam has a shorter horizontal component to be placed in more than desktop, is called crossbeam upper board part, has a longer horizontal component to be positioned at desk hereinafter referred to as crossbeam lower plate portions.Crossbeam lower plate portions has a vertical tapped through hole, crossbeam set bolt screws in from the bottom of this tapped through hole, and upper end screws out, and screws in set bolt top board.Set bolt is precession upwards, makes set bolt Roof below desktop, and the bolt that is firmly tightened makes set bolt top board and crossbeam upper board part clamping desk.Set bolt is to the distance of table edge, less to the distance of table edge from one end away from table edge than crossbeam upper board part.The side of crossbeam lower plate portions is a vertical long flat board, for installing slide rail.Install two crossbeams in a manner described, slide rail is arranged on the inner side of two crossbeams, and the slide block on slide rail is used for fitting key plate rail.
The beneficial effects of the utility model are: provide a kind of can fast and easy fitting key plate rail to the device on desk, and this device does not damage desk.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the isometric view of crossbeam;
Fig. 2 is that install crossbeam is to the front view on desk;
Fig. 3 is that install crossbeam is to the isometric view on desk;
Fig. 4 is that install crossbeam is to the exploded view on desk.
1. crossbeams in figure, 2. crossbeam set bolt, 3. set bolt top board, 4. slide rail, 5. desk.
Detailed description of the invention
In FIG, crossbeam (1) comprises a shorter horizontal component and is called crossbeam upper board part, and a longer horizontal component is called crossbeam lower plate portions, and a shorter vertical portion is called crossbeam vertical portion.Crossbeam lower plate portions has a tapped through hole, and tapped through hole is less than the distance of crossbeam upper board part from the one end away from crossbeam vertical portion to crossbeam vertical portion to the distance of crossbeam vertical portion.
In the embodiment shown in Fig. 2, Fig. 3 and Fig. 4, the upper surface of lower plane laminating desk (5) of crossbeam upper board part, crossbeam vertical portion, near desk (5), can be close to desk (5), also can not be close to desk (5).Crossbeam set bolt (2) screws in from the tapped through hole bottom of crossbeam lower plate portions, screw out from upper end, and be screwed in the screwed hole of set bolt top board (3), precession crossbeam set bolt (2) makes set bolt top board (3) withstand on desk (5) below, firmly screws crossbeam set bolt (2) and makes set bolt top board (3) and crossbeam upper board part clamping desk (5).Install two crossbeams (1) in a manner described, slide rail (4) is arranged on the inner side of two crossbeams (5), and the slide block on slide rail (4) is used for fitting key plate rail.
Claims (1)
