Description of drawings
Fig. 1 is the general structure schematic diagram of the desk of the utility model retractable.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the desk of a kind of retractable of the utility model has existing four fixed supporting legs 4 that vertically are provided with, four fixed supporting legs 4 are put on the shelf and are provided with fixedly desktop 2, these four fixed supporting legs 4 are arranged under four drift angles of fixing desktop 2, guarantee that the utility model multipurpose desk can firmly place on the ground.
Technical characterictic of the present utility model is, this desk also comprises the Guide rollers assembly 1 that is arranged on fixing desktop 2 lower surfaces, fixedly rotating shaft 8 and slip desktop 5.Guide rollers assembly 1 comprises the guide rail and the pulley of mutually nested setting, and this guide rail is made as the guide rail of 90 degree radians, is embedded under the lower surface of fixing desktop 2.And fixedly rotating shaft 8 promptly is arranged on the home position of this 90 degree radian guide rail.
Slip desktop 5 is made as the U type, is connected and fixed the pulley of rotating shaft 8 and Guide rollers assembly 1 on the summit, two right angles of this U type slip desktop 5 respectively.Slip desktop 5 is the axle center with fixing rotating shaft 8, utilizes the pulley of Guide rollers assembly 1 to be free to slide in 90 degree radian guide rails of Guide rollers assembly 1, makes slip desktop 5 can freely take in fixedly desktop 2 times, or from fixedly stretching out the desktop 2.Simultaneously, be provided with in the guide rail of Guide rollers assembly 1 and trigger spring assembly 3, in the time of need stretching out slip desktop 5, trigger spring assembly 3 and can assist slip desktop 5 in the guide rail of Guide rollers assembly 1, to slide.Stretch out on fixing desktop 2 on the side of slip desktop 5 and be provided with active blade 9, when slip desktop 5 need be taken in fixedly desktop 2 times, active blade 9 can pin slip desktop 5.
Slip desktop 5 has movable supporting legs 7.Fixedly connected by active connection 72 between slip desktop 5 and the movable supporting legs 7, this active connection 72 adopts rotatable hinge, movable supporting legs 7 can freely be packed up, and can be close to the following face of slip desktop 5 when packing up.The desktop 5 that slides simultaneously has snap ring 6, is used for fixing the movable supporting legs of packing up 7.
The bottom of movable supporting legs 7 is hinged with pulley 71 by the thicker scalable screw 73 of diameter.These scalable screw 73 rotatable elongation and contractions can suitably be regulated according to the ground environment that this desk is installed, and prevent tumbling and rocking of desktop, keep desktop steady.
Below specify the using method of the desk of the utility model retractable:
When need use slip desktop 5, open active blade 9, utilize and trigger spring assembly 3 ejection slip desktops 5, after shifting out slip desktop 5 fully, from snap ring 6, take out movable supporting legs 7 and put down, movable supporting legs 7 vertically is provided with, and regulates scalable screw 73, make movable supporting legs 7 firm support on the ground, keep whole retractable desk steadily.
When need regaining slip desktop 5, pack up movable supporting legs 7 earlier, be fixed in the snap ring 6 after, again slip desktop 5 is regained fixedly desktop 2 times, close active blade 9 after treating to regain fully slip desktop 5, slip desktop 5 is fixed on fixedly desktop 2 times.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection domain of the present utility model should be limited to the appended claims.
