The specific embodiment

At first, see also Fig. 1～shown in Figure 6, go-kart 1 of the present utility model is provided with tooth row 2 and adjusting device 3 under last plate rail 11, utilizes adjusting device 3 to be placed on rail segment 121 places of support bar 12, and support bar is pivoted for 12 times again and is connected with down plate rail 13;

This tooth row 2, it has two corresponding side tooth sections 21, and this side tooth section 21 is extended with anodontia section 22 more forward, and two form a chute 23 between corresponding, and be provided with pilot hole 24 for being mounted under the plate rail 11 in tooth row 2;

This adjusting device 3, it has holder 31 and can set firmly for the rail segment 121 with support bar 12, has flange 311 in these holder 31 front ends, and convex with protruding button 312 on this flange 311, just can supply on this protruding button 312, being nested with flexible member 32, these holder 31 tops then are extended with flange 313 to both sides, so that this flange 313 is placed on the tooth row 2, and the restriction of plate rail 11 is able to move forward and backward on tooth row 2 in the cooperation, and opened hole slot 314 in holder 31 lower edges, this hole slot 314 also can be established element 315 for spiral shell and establish into rail segment 121 through an external member 316 spiral shells, can limit the position of rail segment 121;

This adjusting device 3 is provided with sliding seat 33 in addition, this sliding seat 33 is by two corresponding blocks 331,332, utilize fixed the closing of bolting element 333 spiral shells mutually, and be concaved with the accommodation space 334 that can supply holder 31 to insert in sliding seat 33, and in accommodation space 334 both sides corresponding rail segment 121 is formed with perforation 335, outwards protruded out group plate 336 in sliding seat 33 1 blocks 331,332 corresponding tooth row 2 side tooth sections 21 of another block are formed with two corresponding latches 337, go in the tooth of side tooth section 21 just can utilize latch 337 clips, be arranged with in block 332 again and be formed with tank 338, these tank 338 corresponding holder 31 flanges 311 have been opened grooved bore 339, be able to stretching in the tank 338 of pulling by grooved bore 339 for flange 311, and flexible member 32 is inserted be nested with in the tank 338 on flange 311 protruding buttons 312;

Main improvement of the present utility model exists: in the chute 23 of two corresponding 2 formation of tooth row, one sidewall fovea superior tool forms the draw-in groove 25 of respective side tooth section 21 length, and forms inclined plane 26 in the curved tool of the sidewall front end of chute 23; In addition, on sliding seat 33, be pivoted with a clamping rod 4 by bolting element 41 and torque spring 42, these clamping rod 4 one ends extend in the chute 23 and to chute 23 these sidewalls and are bent to form grab 43, the grab 43 that makes clamping rod 4 by the elastic force of torque spring 42 just can the draw-in groove 25 of urgent clip on chute 23 these sidewalls in, make and head on plate rail 11 and can't be pulled pivot with clamping rod 4 pivots sliding seat 33 tops even, again, be convexly equipped with formation forward in holding in addition of clamping rod 4 and pull sincere 44, for utilizing finger to pull, the grab 43 that clamping rod 4 is held in addition can break away from the draw-in groove 25 on chute 23 these sidewalls.

When implementing to adjust the height of going up plate rail 11, see also Fig. 3～shown in Figure 6, can utilize finger to pull pulling of clamping rod 4 sincere 44 earlier, the grab 43 that clamping rod 4 is held in addition breaks away from the clip of draw-in groove 25 on chutes 23 sidewalls, and then pull sliding seat 33 dial plate 336, latch 337 is separated with the side tooth section 21 of tooth row 2, can adjust the position of whole adjusting device 3 at tooth row 2 this moment, reach the purpose of adjusting the height of plate rail 11 on this simultaneously, decontrol afterwards pulling out pulling of plate 336, can utilize the elasticity of 32 pairs of sliding seat 33 of flexible member to hold, making latch 337 recover original pressure elasticity clip with side tooth section 21 smoothly combines, unclamp again clamping rod 4 is pulled sincere 44 pulling, then clamping rod 4 will be made by the elastic force of its torque spring 42 in the draw-in groove 25 of card an ancient unit of weight 43 urgent clips on chute 23 sidewalls of clamping rod 4, and the plate 336 that pulls out of sliding seat 33 can't be pulled again, to reach the purpose of dual location.

When whole go up plate rail 11 desire down with play plate rail 13 works press close to most fold the time, see also Fig. 3～shown in Figure 6, the same finger that utilizes is earlier pulled pulling of clamping rod 4 sincere 44, card an ancient unit of weight 43 that clamping rod 4 is held in addition breaks away from the clip of draw-in groove 25 on chutes 23 sidewalls, and then pull sliding seat 33 dial plate 336, latch 337 is separated with the side tooth section 21 of tooth row 2, and adjust whole adjusting device 3 smoothly up to entering anodontia section 22 of tooth row 2, can decontrol and pull out plate 336 and pull sincere 4 pull, this moment clamping rod 4 the also corresponding inclined plane 26 that enters chute 23 sidewalls away from the draw-in groove 25 on chute 23 sidewalls, grab 43 positions, simultaneously can continue to adjust its position, plate rail 11 is continued toward descending up to doing nearest applying and put the place with following plate rail 13, to reach the purpose that minimum folds volume.

When the whole go-kart that folds 1, when desiring to re-use, to go up up pull-up of plate rail 11 again as long as pin down earlier plate rail 13, then because the chute 23 sidewall front ends of 2 formation of corresponding toothrow form inclined plane 26, add that tooth row 2 front ends form anodontia section 22, so the grab 43 of military order clamping rod 4 and the slippage backward smoothly of the latch 337 on the sliding seat 33, go in the draw-in groove 25 on chute 23 sidewalls and end Deng the grab 43 slippage clips of clamping rod 4, at this moment, adjusted according to the height mode of plate rail 11 in the above-mentioned adjustment again and got final product.

From the above mentioned, structure composition of the present utility model and implementation are as can be known, the utility model is adjusted the height of go-kart and when adjusting the position of whole adjusting device at tooth row when desire, must pull the plate of dialling of sliding seat earlier, latch is separated with the side tooth section of tooth row, just can adjust its position smoothly, yet, sliding seat and clamping rod combine because of being pivoted, and in the draw-in groove of grab clip on chute wall of clamping rod, make the sliding seat top head on plate rail and can't be pulled pivot, so desire to pull the plate that pulls out of sliding seat, then must pull the sincere portion of pulling of clamping rod earlier, the grab that clamping rod is held in addition breaks away from the clip of draw-in groove on the chute wall, thereby can reach the effect of dual location, and more increasing go-kart has higher security in the use.
