The upper handle long hole of 701-, 8- spacer sleeve, 9- lower push-rod, 10- locking pin, 11- locking set.
Specific embodiment
The present invention will be further described below with reference to the drawings.
As shown in Fig. 1, folding children's vehicle handle sliding sleeve locks joint, including upper handle 7 and lower push-rod 9, under upper handle 7
Portion is parallel by rotational pin 5 with 9 top of lower push-rod, connects and is rotatablely connected respectively with rotational pin 5 side by side, and upper handle 7 is pushed away under
Spacer sleeve 8 is set on rotational pin 5 between bar 9, spacer sleeve 8 and upper handle 7, the support of lower push-rod 9 connect；Upper 7 lower part of handle
Sliding sleeve 6 is slidably connected, 6 upper end of sliding sleeve is provided with sliding sleeve convex platform 602, and corresponding 5 position of rotational pin is provided with sliding sleeve long hole
601, rotational pin 5 is slidably connected with sliding sleeve long hole 601；The side of corresponding lower push-rod 9 is provided with sliding sleeve lower convex platform 603, under sliding sleeve
603 lower end of boss is provided with the sliding sleeve groove 604 of lower ending opening, is connected with lock on the lower push-rod 9 of corresponding 604 position of sliding sleeve groove
Rationed marketing 10, the affixed locking set 11 to match with sliding sleeve groove 604, locking set 11 and about 604 sliding sleeve groove on locking pin 10
Sliding is by being tightly connected；The affixed tension spring articulated pin 4 in 6 lower part of sliding sleeve is corresponded to and is provided on the upper handle 7 of 4 position of tension spring articulated pin
Handle long hole 701, tension spring articulated pin 4 are slidably connected with upper handle long hole 701；Upper 7 lower end of handle is provided with inner support plug 1, inner support
Plug 1 is connect with upper 7 stretching of handle, and 1 upper end of inner support plug passes through the detachable affixed tension spring 3 of tension spring fixed pin 2,3 upper end of tension spring and drawing
Spring articulated pin 4 mounts.The folding children's vehicle handle sliding sleeve sliding over for joint of locking pulls up sliding sleeve convex platform and tension spring
