Detailed Description

The invention will be further described with reference to the following drawings and examples:

embodiment, as shown in fig. 1 to 7, a foldable shelf comprises a shelf body 1 and a panel 2, wherein the shelf body 1 comprises a front frame 3, a rear frame 4, a connecting rod 5, a brace 6, a rivet 7, a rivet 8 and a cushion 9.

The bottom of fore-stock 3 and after-frame 4 all is provided with the regulation podotheca 10 that is used for height-adjusting, the bottom position of after-frame 4 is equipped with crossbeam 41, the interval is provided with three connecting rods 5 of group between fore-stock 3 and the after-frame 4, 8 covers of blind rivet are put and are put the cushion 9 that reduces friction, and blind rivet 8 passes connecting rod 5 front end lock on fore-stock 3, realizes that connecting rod 5 front end and fore-stock 3 articulate together, and blind rivet 8 passes connecting rod 5 rear end lock on after-frame 4, realizes that connecting rod 5 rear end and after-frame 4 articulate together.

The front end of the brace 6 is provided with a through hole 61, the rear end of the brace 6 is provided with a clamping groove 62, the clamping groove 62 is a U-shaped groove, the distance between the center of the through hole 61 and the center of the clamping groove 62 is 70 mm, the rivet 7 penetrates through the through hole 61 to be locked on the connecting rod 5 close to the bottom of the frame body 1, and the brace 6 rotates by taking the rivet 7 as a rotating center.

The panel 2 is fixed on the top surface of each group of connecting rods 5, the connecting rods 5 upwards support the panel 2, and the panel 2 turns over along with the connecting rods 5.

The working principle is as follows:

when the shelf is unfolded, the front shelf 3 and the rear shelf 4 are respectively perpendicular to the connecting rod 5, then the brace 6 is rotated to be close to the cross beam 41, and the cross beam 41 is inserted into and clamped in the clamping groove 62 of the brace 6, so that the connecting rod 5, the brace 6 and the rear shelf 4 form a right triangle, and the included angle between the brace 6 and the connecting rod 5 is smaller than 60 degrees, so that the brace 6 locks the front shelf 3, the rear shelf 4 and the connecting rod 5.

Because right triangle's stability is strong and brace 6 and connecting rod 5, the cooperation of after-poppet 4 to retrain the rotational degree of freedom of whole support body 1, reached the purpose of support body 1 tensioning, locking, avoided support body 1 to warp, in addition, when connecting rod 5 was perpendicular with after-poppet 4, rotated brace 6, draw-in groove 62 of brace 6 was located crossbeam 41 department just, thereby avoided brace 6 and crossbeam 41 to unhook.

When folding supporter, at first break away from crossbeam 41 in draw-in groove 62 of brace 6, then rotate brace 6 and keep away from crossbeam 41, remove front stall 3 or after-frame 4 at last to make front stall 3 and after-frame 4 be close to each other, thereby reduce the volume of supporter, convenience of customers removes and accomodates.
