Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
As shown in Figure 1 to 4, a kind of desk of foldable telescopic, the upper table bulk 1 comprising telescopic table pin, the lower table bulk 2 be fixedly connected with table pin and be arranged on above lower table bulk 2, described upper table bulk 1 is connected by folding liftable mechanism 6 with lower table bulk 2.
In the present embodiment, described table pin comprises lower table pin 3, the elevating lever 4 that can relatively descend table pin 3 to slide up and down, can OQ t bar 4 slide up and down serve pin 5, described in serve pin 5 and be fixedly connected with lower table bulk 2.
In the present embodiment, described lower table pin 3 is provided with vertical chute A301, described elevating lever 4 is provided with the slide block A402 be slidably matched with vertical chute A301, described elevating lever 4 is provided with vertical chute B401, described in serve the slide block B 501 pin 5 being provided with and being slidably matched with vertical chute B401.
In the present embodiment, described vertical chute A301 and vertical chute B401 is provided with some fixed vias running through lower table pin 5 sidewall or elevating lever 4 sidewall, described slide block A402 and slide block B 501 are provided with the spring catch 10 coordinated with fixed via.
In the present embodiment, described folding liftable mechanism 6 comprises the folding liftable bar being arranged on guide rail 7 on the left of lower table bulk 2, being arranged on the screw rod 8 that can rotate relative to lower table bulk 2 on the right side of lower table bulk 2, the guide rail 7 being arranged on upper table bulk 1 arranged on left and right sides and being slidably matched with screw rod 8 or guide rail 7.
In the present embodiment, described screw rod 8 is double rotational directions screw rod.
