The utility model will be further described below in conjunction with embodiment for the specific embodiment.
As shown in Figure 1, a kind of folding rack that is used for folding table/chair comprises link 1 and following link 2, and last link 1 and following link 2 are hinged, described going up on the link 1 is provided with a hole 12 when holding state Yu in following link 2 overlapping areas, following link 2 is provided with a hole 23 at correspondence position; One pivot pin 31 is set, and the diameter of pivot pin 31 is less than the aperture; When holding state, pivot pin 31 inserts in two holes.
As shown in Figure 2, described hole 12 extends to form a chute 11 along last link 1 length direction, and pivot pin 31 passes chute 11, and the two ends size of pivot pin 31 is greater than the bore of chute 11, and the diameter in pivot pin 31 stage casings is less than the bore of chute 11; Hole 23 extends in the overlapping end formation U-shaped jag 21 of holding state and last link 1 chute 11 along link 2 length directions down, and these jag 21 bores are equal to or greater than the bore of link chute 11.When chute 11 and U-shaped jag 21 were overlapping, pivot pin 31 moved to chute 11 and U-shaped jag 21 overlappings and plays a part to pin and go up link 1 and following link 2.
As shown in Figure 3, described hole 12 extends to form a blind groove 13 for blind hole along last link 1 length direction, and the notch bore of this blind groove 13 is less than the cell body internal diameter, and an end of pivot pin 31 places in the cell body.
The other end of described pivot pin 31 is provided with one and holds cover.The design of holding cover is that the operator takes or the push-and-pull pivot pin for convenience.Holding cover also can replace with fixed cover.
As Fig. 4, shown in Figure 5, described go up is provided with the fixed cover 3 that can move freely along the link length direction on the link 1, and last link 1 passes fixed cover 3, and the two ends of pivot pin 31 are fixed on the fixed cover 3; When last link is in the Support Position with following link, fixes 3 covers and move to the position of going up link 1 and following link 2 with pivot pin 31 to the small part containing.Chute 11 limits the distance that fixed cover 3 moves.
The length of described fixed cover 3 is between 15 millimeters to 150 millimeters.Fixed cover can be to be made of metal, and also can be plastic products.
As shown in Figure 6, ear 22 is pulled in the formation that stretches out abreast of the central axis of the side at U-shaped jag 21 places of described down link and pin joint.Pull ear 22 in the setting of the termination of following link 2 and can pull link 2 down more like a cork.
The described development length of ear 22 of pulling is between 12 millimeters to 100 millimeters.Minimum length will satisfy at least is convenient to pushing of thumb.
As shown in Figure 5, described fixed cover 3 near an end setting of pin joint with pull the breach 32 that ear 22 matches.Pull ear 22 some on following link 2 and the position is set can stops moving of fixed cover 3, therefore pull ear and be arranged on when stoping the position, fixed cover 3 correspondences are provided with breach 32 in this position and pull ear 22 with containing.
As shown in Figure 7, the utility model is applied in a folding desktop and is in the state that supports table leg; The table leg of shown in Figure 8 is this folding desktop is in the folding state of regaining.
