Description

The group-setting structure of front jocket wheel in children's buggy

The utility model relates to the group-setting structure of front jocket wheel in a kind of children's buggy.

As depicted in figs. 1 and 2, traditional children's three-wheel hand push 50 is all to have set up location wheel 51 at the car body two ends, be installed with a front jocket wheel 52 forwardly, this front jocket wheel 52 utilizes the retaining sleeve 531 that is positioned on two side skeletons 53 of car body 50 the place aheads to fix, after the opening 532 that is about to two retaining sleeves 531 will overlap respectively and is through the two ends of front jocket wheel 52 axostylus axostyles 521, lock with bolting element again and locate.

When promoting this child's tricycle, the handrail 54 of operation car body rear end advances front jocket wheel 52 or retreats, but the group-setting structure of above-mentioned three-wheel vehicle front jocket wheel can only make front jocket wheel 52 do to advance or retreat, and can't carry out left rotation and right rotation, make the convenience of hand barrow 50 have a greatly reduced quality.

Purpose in the utility model is to provide a kind of group-setting structure that can make operations such as the three-wheel vehicle front jocket wheel is realized advancing easily, conversion direction.

To achieve these goals, in the utility model in the child's tricycle group-setting structure of front jocket wheel be to stride frame by between two side skeletons in car body the place ahead and front jocket wheel, setting up one, wherein,

Described extension rod, be preset with a through hole at its front end, insert two corresponding covers that articulate up and down respectively at the upper and lower opening place of this through hole, and above last pivot joint cover, be provided with one and be beneficial to and carry out the solid pad of spiral shell, and be provided with a pivot joint block in the extension rod rear end, both sides at this pivot joint block respectively are provided with a through hole, then are provided with one at the front end of this pivot joint block and are used to wear a slotted hole that has an axostylus axostyle of pulling piece;

Described cross-over connection portion is provided with a nose bar in the top, be provided with a spacer in this nose bar lower end, and be provided with a U type frame again in the bottom of this spacer, these U type frame both sides respectively are socketed with a retaining sleeve, this retaining sleeve is provided with a hole, and has an opening in the bottom of this retaining sleeve;

Central portion at described front jocket wheel is equipped with described axostylus axostyle, and an end of this axostylus axostyle is provided with a catch and and pulls piece.

When children's buggy adopted above-mentioned group-setting structure, the user only need just can utilize and stride frame and order about leading crop rotation left rotation and right rotation by the handrail of operation car body, direction is controlled, thereby can be realized easily advancing, operation such as conversion direction.

Below in conjunction with accompanying drawing concrete structure of the present utility model, practical effect and a specific embodiment are described in further detail.

Fig. 3 is the three-dimensional exploded view of buggy in the utility model;

Fig. 4 is the cross-sectional schematic of front jocket wheel group-setting structure in the utility model;

Fig. 5 is the combination stereogram of front jocket wheel group-setting structure in the utility model.

As shown in Figure 3, in the utility model in children's buggy the group-setting structure of front jocket wheel mainly be between two side skeletons 11 in car body 1 the place ahead and front jocket wheel 3, to have set up one to stride frame 2, this is striden frame 2 and is made up of extension rod 21 and cross-over connection portion 22.

Wherein, extension rod 21 is preset with a through hole 211 at its front end, inserts the two corresponding covers 212 that articulate up and down respectively at the upper and lower opening place of this through hole 211, and last pivot joint is overlapped 212 tops and is provided with one and is beneficial to and carries out the solid pad of spiral shell 213; Be provided with a pivot joint block 214 in the rear end of extension rod 21, and respectively be provided with a through hole 2141 in the both sides of pivot joint block 214, and being provided with a slotted hole 2142 at the front end of pivot joint block 214, this slotted hole 2142 is used to wear one and has the axostylus axostyle 2143 of pulling piece 2144, as shown in Figure 5.

Cross-over connection portion 22 is provided with a nose bar 221 in the top, be provided with a spacer 222 in the lower end of this nose bar 221, and be provided with a U type frame 223 in the bottom of spacer 222, the two ends of this U type frame 223 respectively are socketed with a retaining sleeve 2231, simultaneously, on retaining sleeve 2231, be provided with a hole 2233, and be provided with an opening 2232 in the bottom of this retaining sleeve 2231.

Front jocket wheel 3 locates to be equipped with an axostylus axostyle 31 in the central, and is provided with a catch 32 and at an end of this axostylus axostyle 31 and pulls piece 33.

When group is established and implement this child's tricycle, as shown in Figure 4 and Figure 5, at first in the through hole 211 of extension rod 21, cover and articulate cover 212 up and down, again with the nose bar 221 of cross-over connection portion 22 in through hole 211, then, pad 213 is placed on the articulated section 212, carry out the spiral shell fixed bit with a bolting element again, constitute one and stride frame 2.Through hole 2141 covers with pivot joint block 214 both sides are through on the retaining sleeve 111 of 1 liang of side skeleton 11 of car body again, the opening sleeve of retaining sleeve 111 is connected on the axostylus axostyle 2143, adjust bolting element again and make the catch hook in the hole of retaining sleeve 111, it is fitted tightly, push again and pull piece 2144, and be the strong fix shape so that bolting element is resisted against on the retaining sleeve 111.In addition, the opening 2232 of U type frame 223 two ends retaining sleeves 2231 in the cross-over connection portion 22 is set up in the two ends of axostylus axostyle 31 in the front jocket wheel 3, again by adjusting bolting element and making in the hole 2233 of catch 32 hooks on retaining sleeve 2231, it is fitted tightly, at last, push again and pull piece 33, and be the strong fix shape so that bolting element is resisted against on the retaining sleeve 2231.

In use, only need the handrail 12 of operation car body 1 rear end, utilize and stride frame 2 and order about front jocket wheel 3 and make left rotation and right rotation and direction is controlled, can realize advancing the operation of conversion direction easily.

In sum, the group-setting structure of buggy front jocket wheel can reach its intended purposes and effect really in the utility model, and more even more ideal, practical than traditional children buggy.
