Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail：

Specific embodiment as shown in Figure 1 and Figure 2, a kind of go-kart of adjustment height, including upper disk 1 and chassis 2, upper disk 1 with Connecting rod is provided between chassis 2, and upper disk 1 is provided with a pocket 3, and the bottom surface on chassis 2 is provided with universal wheel, described connecting rod bag Upper boom 4 and lower beam 5 is included, upper boom 4 is connected with upper disk 1, and lower beam 5 is connected with chassis 2, upper boom 4 is directly connected by regulating part with lower beam 5 Connect, upper boom 4 be sleeved in regulating part and with the spacing cooperation of regulating part.The length that upper boom 4 is inserted in is adjusted by regulating part, realizes learning On step car, the vertical lift adjustment of disk 1, facilitates the infant of adaptation differing heights, it is to avoid using scissors lift structure, can Caused by energy, Support Position change causes centre-of gravity shift, and then prevents the danger such as rollover, while avoid crushing infant Problem occur.

Further, described regulating part include mandrel 6 and side set 7, as shown in figure 3, side set 7 be hollow cylinder structure simultaneously 6 two ends of mandrel are hinged on, side covers the spacing hole 8 that 7 side walls are provided through its body, and upper boom 4 is set with spacing with spacing hole 8.Borrow Help the restraining position of upper boom 4 and spacing hole 8, it is ensured that the position height of upper disk 1 is adjustable.

Further, it is provided with position limiting structure in described side set 7, described position limiting structure includes reset spring washer 9, spacing Plate 10 and button 11, button 11 are arranged on side and cover 7 end faces, and limiting plate 10 is engaged with reset spring washer 9 by button 11, described Limiting plate 10 be provided with and be set with the through hole for coordinating with upper boom 4, be provided with dead bolt 12 in through hole, dead bolt 12 be arranged on upper boom 4 The 13 spacing cooperation of locked groove of side wall.Position limiting structure when in use, press button 11, button 11 to side set 7 in move, dead bolt 12 with Move after limiting plate 10, as rear shift-in is gone, dead bolt 12 contacts spacing with the locked groove 13 on upper boom 4, now extracts or insert Upper boom 4, in realization, disk 1 is moved in the position of vertical direction, now loosens button 11,12 resilience of dead bolt and again with upper boom 4 on Locked groove 13 it is spacing, realize positioning, operation is simple and reliable, and adjustment is flexible.

Further, this utility model storage when not in use for convenience, described upper boom 4 and lower beam 5 respectively with Upper disk 1 and chassis 2 are hinged, and mandrel 6 is fixedly connected with lower beam 5, and 6 upper end of mandrel is provided with horizontal direction fix bar 14, fix bar 14 two ends are provided with and are relatively fixed groove 15 with upper boom 4, upper boom 4 and 15 spacing cooperation of fixing groove.During use, by fixing groove 15 It is spacing with upper boom 4, it is ensured that the linearity of upper boom 4 and lower beam 5 preferably, in stress connecting rod integrally do not bend, it is overturning-free, Gu Fixed pole 14 stops that upper boom 4 excessively overturns, it is ensured that normal to use, and when pleated, pushes away regulating part to body inner side, fix bar 14 with Upper boom 4 departs from spacing, overturns into car body by articulated structure of the mandrel 6 between upper boom 4 and lower beam 5 with side set 7, so as to reality Existing upper boom 4 is turned to horizontality with lower beam 5 by plumbness, it is achieved thereby that the storage of car body, reduces space hold.

Further, as side 7 spaces of set are less, and cause upper boom 4 to release to prevent from touching by mistake, need reset spring washer 9 Have larger elastic force, the elastic sheet metal of described reset spring washer 9 for arcuate structure, the arc apex of reset spring washer 9 with it is spacing Plate 10 is engaged.By the sheet metal structure of arc, there is provided larger elastic force, while it is little to take up room, being capable of convenient cloth Put in side set 7.

Further, for 4 end of the upper boom scratch user for preventing from extending, described 4 end of upper boom is set with Protection ball cover 16.

Further, as shown in figure 4, described chassis 2 is additionally provided with supporting spring 17, supporting spring 17 is fixed on by connecting rope 18 2 center of chassis.Have no time to keep an eye on infant in the head of a family, when needing to fix baby truck position, supporting spring 17 is bundled in chassis 2, is made The foot of user is not contacted with ground, so as to avoid stroller displacement, it is ensured that the safety for using.
