The specific embodiment

Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.

Embodiment:

The fold mechanism of cycle with slide plate as shown in Figure 1 has base plate 4, is fixed with U-shaped covering of the fan plate 1 on the base plate, and herringbone fork 6 is hinged by anchor shaft 3 and U-shaped covering of the fan plate 1.Herringbone fork 6 is provided with the bar hole of splitting 61 near anchor shaft 3 one ends; One side of U-shaped covering of the fan plate 1 fan-shaped arc has two pairs of U-shaped through holes, i.e. U-shaped through hole 1 and U-shaped through hole 2 12, and wherein U-shaped through hole 1 carries out reaming (promptly forming the Ω hole) in the U-shaped bottom; Latching device is housed on the fold mechanism, comprises that the tight locking button 9, of a drag hook 5, one band bearing pins has jam nut 2, one retracing springs 8 of step.In the tight locking button 9 of jam nut 2, band bearing pin and the bar hole 61 that is flush-mounted in herringbone fork 6 after drag hook 5 links to each other, retracing spring 8 is connected between drag hook and the anchor shaft 3, is with the axle head of the tight locking button 9 of bearing pin that wrench 91 is housed.

During use, by the folded state of Fig. 3 open mode to Fig. 4, can be by following operation:

Be pulled upwardly drag hook 5 along the bar hole 61 on the herringbone fork 6, make the U-shaped through hole 2 12 on the tight locking button 9 disengagement U-shaped covering of the fan plates 1 of being with bearing pin, rotate herringbone fork 6 around anchor shaft 3, make jam nut 2 aim at U-shaped through hole one 11 opening parts, decontrol drag hook 5, retracing spring 8 promptly retracts the tight locking button 9 of band bearing pin in the U-shaped through hole 1, in the U-shaped through hole 1 on the jam nut 2 screw-in U-shaped covering of the fan plates 1 that have step, pull down the spanner 91 of the tight locking button 9 of band bearing pin, can lock.
