Description
Technical field
The utility model relates to daily household field, is specifically a kind of overlapping stretching table.
Background technology
Desk is common office furniture or home furnishings, use frequent in mankind's activity, owing to limiting by place, the size of desk can not be excessive to save space, but as many people have a dinner party or practice calligraphy time, often need to use larger table demand, be subject to people in the desk that it is possible to adjust table area and welcome.
In order to increase table area, there are the folding and two kinds of modes that stretch, when using folding table, sub-panel utilize the elements such as hinge and main table plate hinged, structure is simply implemented conveniently, but during one side folded state, the elements such as hinge are subject to folding panel gravity effect for a long time, easily come off or be out of shape, folding panel nature suspension status easily affects the leg room of user on the other hand.
Stretching table is owing to needing to be in same plane when auxiliary table and main table plate use, design often adopts polylith sub-panel, adopts independent slide rail separately, combine during gathering, release during expansion, centre holds up one piece with other elements again and lengthens the effect that table reaches area increase.Its structure of stretching table of prior art generally comprises and comprises table, table frame, the table leg be connected in described table frame, described table comprises table and lower table, described table frame inner surface is provided with the rail system that can adjust table and lower table upper-lower position, upper table and lower table are respectively provided with two bearings, and bearing two ends are provided with the pulley coordinated with described rail system.
In above-mentioned technical scheme, when needing small size to use, upper table and described lower table are slided on described rail system, make described upper table become upper and lower lamination with lower table; When needing large area to use, upper table and lower table slide, and described upper table is connected with lower table, is in a plane, reach the effect increasing usable floor area.But in use still can there is following problem:
1: getting on the right track is connected with lower railway the first linkage section, namely when processing is got on the right track with lower railway, getting on the right track and between lower railway, leaving the space passed through for the roller on table, and this space respectively with arrange vertical with lower railway of getting on the right track, and the roller of table is when by this space, resistance is comparatively large, inconvenient during stretching;
2: when desk is in layer-by-layer state, table easily horizontally slips, when people also has people can arrange clip for preventing table from horizontally slipping in table frame, namely one end of clip and table frame are fixed, the other end of clip contacts with table surface, although can play the effect preventing table from horizontally slipping to a certain extent, once firmly pull table, table still can move left and right, and clip be arranged on table frame top can affect people use.
Summary of the invention
