Detailed description of the invention

For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:

Refer to Fig. 1, the present invention includes top and bottom all uncovered, the casing 17 of rectangular shape, be fixed with end cap 16 in the bottom of casing 17.In the present embodiment, end cap 16 adopts multiple sunk screw 15 to fix with casing 17, is convenient to assembling and the maintenance of Picnic table like this.

The inwall of casing 17 is provided with upwards non-through slideway 9, and be also provided with the elevator 4 of bottom with projection at the inner chamber of casing 17, projection is positioned at slideway 9, and elevator 4 can along slideway 9 stably vertically movement.Be hingedly connected with two desktops 2 in left and right at the top of elevator 4 by jointed shaft 3, after desktop 2 horizontal development, form whole desktop, vertically folding after to fall into the inner chamber of casing 17 with elevator 4.It should be noted that jointed shaft 3 place between desktop 2 and elevator 4 should adopt tight fit connection, desktop 2 open after should be able to stable maintenance in level.

In the present embodiment, pull out for the ease of the inner chamber of desktop 2 by casing 17, the marginal center being positioned at outer end at each desktop 2 is provided with drop handle 1.

The jack 5 of lateral direction penetrating is provided with at the middle part of elevator 4.

The outer wall of casing 17 is also provided with multiple vertical accommodating groove 11, is equipped with the open-work 12 of lateral direction penetrating in the lower end of each accommodating groove 11, jack 5 and each open-work 12 horizontal alignment when elevator 4 is down to low level.As shown in Figure 2, accommodating groove 11 and support arm 10 are set to 4 groups, and two outer walls that casing 17 is relative respectively arrange 2 groups.

In each accommodating groove 11, support arm 10 is all installed, support arm 10 comprises two ends and is equipped with externally threaded connecting rod 8, be connected with upper bush 7 at threaded upper ends, lower end has been threaded lower sleeve 13, the upper end employing hinge 6 of upper bush 7 is arranged on the top of accommodating groove 11, the lower end of lower sleeve 13 and adopts hinge 6 to be provided with holdfast 14.The adjustment of support arm 10 entire length can be realized by being rotationally connected bar 8, when Picnic table is received, support arm 10 should be adjusted to the state isometric with accommodating groove 11, when Picnic table launches, each support arm 10 should fully extend, and each holdfast 14 is fixed in the face of Picnic table with heading into.

Fig. 2 is the structural representation of folding storage state, can find out by being operating as to folding storage state of the deployed condition in Fig. 1: folding two desktops 2 of doubling make it to fit together, decline in company with elevator 4 afterwards and fall into the inner chamber of casing 17, until the bottom of elevator 4 contacts with end cap 16, jack 5 and each open-work 12 horizontal alignment; Each holdfast 14 is extracted by ground, is rotationally connected bar 8 and makes support arm 10 return to the length of accommodating groove 11; Hand-held holdfast 14 penetrates jack 5 via open-work 12 afterwards, and the operation of each support arm 10 is identical.After each support arm 10 completes storage, elevator 4 is locked in the bottom of casing 17 inner chamber by each holdfast 14, cannot move; Now can be moved by drop handle 1 portable Picnic table.
