The specific embodiment
Below in conjunction with the description of drawings specific embodiments:
Embodiment one
A kind of folding joint of improvement and latching device thereof, it comprises first folded formation 1, second folded formation 2, hinge 3, latch segment 5, pipe fitting 10,11 and locking operation parts; Described first folded formation 1 and second folded formation 2 are hinged by hinge 3; In the corresponding position of first folded formation 1 and second folded formation, 2 sealed places, the latch segment 5 on band inclined-plane is arranged, an end of latch segment 5 and second folded formation 2 are articulated in second folded formation, 2 outsides by axle 13; Latch segment 5 can rotate around axle 13; First folded formation 1 is provided with in the relevant position and locks the inclined-plane that piece 5 compresses; Operating unit and elastic body drive latch segment 5, and the inclined-plane of latch segment 5 is compressed or unclamp the inclined-plane of first folded formation, first folded formation 1 and second folded formation 2 are compressed or unclamp.
Described operating unit is formed by handle hinge 6 pivotally attached pull bars 9 and nut engaged 8 by the eccentric cam 4 of band handle with eccentric cam, pull bar passes arc pad 14, latch segment 5, elastic body 7 successively and the hole 21 be located on second folded formation is threaded with nut 8, pull the handle of eccentric cam 4, the centering error distance that is produced can make latch segment 5 inclined-planes and first folded formation, 1 cooresponding inclined-plane compress; Elastic body 7 plays reset response when eccentric cam unclamps latch segment.
