Detailed description of the invention

Execute example 1.See Fig. 1 a-b: children trolley is bilateral symmetry, every side has included handle pipe (1), front foot pipe (2), rear foot tube (3) etc., forward and backward pin pipe lower end is fixed with wheel (7) respectively, front foot pipe (2) upper end and homonymy handle stem pipe 1) lower end by large joint (6) be flexibly connected, handle pipe (1) upper end is plugged in the interior riveted joint of front port (521) of handle main part lower end (52), and rear foot tube (3) upper end is plugged in the interior riveted joint of rear port (522) of handle main part lower end (52).Launch under using state in go-cart, the handle pipe (1) of homonymy and front foot pipe (2) are stablized and are held in same straight line.

See Fig. 4 and contrast Fig. 1 b: the lower end (41) of handle lid (4) inserts the lower end hollow (512) of handle main part groove (51), inside handle lid, some embedding bar (42) correspondence of (43) inserts the vertical cover (513) of handle main part groove (51), then handle lid (4) and handle main part (5) fasten is an entirety, and this entirety be space reverse body (namely each cylindric vertical cover (513) although axis parallel not comprise by same plane, and the spatial altitude of vertical cover (513) also changes gradually), see Fig. 1 b and Fig. 2 a.It should be noted that, handle lid (4) is integrated not by other fastener with handle main part (5), during for being separated handle lid (4) with handle main part (5), because the service direction of handle main part groove (51) lower end hollow (512) is exited in handle lid (4) lower end, the direction exiting the vertical cover (513) of handle main part (5) with (43) embedding bar (42) inside handle lid is inconsistent, and direction differs greatly, if be not difficult to again disassemble handle lid (4) and handle main part (5) by instrument, thus the design's handle ensure that the reliability of overall integration all the time, so normally can use on children trolley.

See Fig. 2 a-c and Fig. 3: when rear foot tube (3) upper end againsts the rear end (5222) of handle main part (5) rear port (522), rear foot tube (3) forms an appropriate acute angle with the handle pipe (1) on same straight line, front foot pipe (2), and now go-cart is overall deployed condition.When rear foot tube (3) upper end againsts the front end (5221) (the dotted line position in Fig. 3) of handle main part (5) rear port (522), rear foot tube (3) realizes the parallel laminating with front foot pipe (2), and now go-cart is just foldable integral state.Launch between folded state in the entirety of go-cart, correspond to the displacement conversion of rear foot tube (3) upper end between the front end (5221) and rear end (5222) of handle main part (5) rear port (522).But be relatively provided with resistance fixture block (5223) between the front end (5221) of rear port (522) and rear end (5222), two resistance fixture block (5223) transposition transition to rear foot tube (3) upper end have the inhibitory action of appropriateness, only afterburning in one-tenth human operator appropriateness, cause rear foot tube (3) upper end to promote local, resistance fixture block (5223) place trace outer (by means of the elasticity of plastic) by force, rear foot tube (3) upper end just can complete replaces between the front end (5221) and rear end (5222) of rear port (522).
