Abstract

The utility model relates to a steering head bowl set of children's cycle with a limitable rotating angle. At least one stopper is convexly and arranged downwards on the bottom edge of the lower ball bowl of the steering head bowl set of the children's cycle with the limitable rotating angle, and a sliding room is correspondingly arranged on a spacing ring which is arranged between a lower ball stopper and a front fork bracket. A blocking section is respectively arranged on both sides of the sliding room. The blocking sections are sheathed in the inner part of the sliding room through the stopper, and the sliding room is blocked by the blocking sections. The rotating angle of the steering head bowl set which is the lower ball bowl can be limited, and the purpose of riding safely can be achieved.

Description

Has the baby carrier head bowl group that can limit the anglec of rotation

The utility model relates to a kind of headstock bowl group, particularly relates to a kind of child of raising and drives the baby carrier head bowl group that having of safety can be limited the anglec of rotation.

As shown in Figure 1, existing headstock bowl group is on a head tube 1, following two ends are equiped with on one bowl group 2 and bowl group 3 once respectively, following bowl group 3, it is pearl bowl 301 and be equiped with a pearl nest 303 between the pearl plug 302 once once, this time pearl plug 302 also can supply a front forked frame 4 sockets, and front forked frame 4 tops are linked again with a stem 5 that is passed by last bowl group 2 tops, when swing handle standpipe 5, but but interlock front forked frame 4 and down pearl plug 302 by the rolling characteristic of pearl nest 303 down with respect to pearl bowl 301 down, head tube 1 rotates, and control vehicle rotates in the security standpoint scope and the purpose of moving direction to reach.

Though, this headstock bowl group is by widespread usage, even perambulator is no exception, but during because of swing handle standpipe 5, before frame 4 rotations that can produce 360 degree again with respect to head tube 1, and because the child can not accurately control the application of force of swing handle standpipe 5, tend to twist grip standpipe 5 rapidly in driving, and because rotational angle excessive and feasible before, the inertia direction of trailing wheel is conflicted mutually, fall even damage and cause, so there is further regulation in country such as America and Europe for the safety check of perambulator at present, rotational angle that promptly must restriction baby carrier head bowl group, the safety when guaranteeing to drive.

The purpose of this utility model be to provide a kind of make stem and before again frame can only in predetermined rotational angular, rotate, drive the baby carrier head bowl group that having of safety can be limited the anglec of rotation to reach.

The utlity model has the baby carrier head bowl group that can limit the anglec of rotation, the bowl of pearl once of this headstock bowl group and be equiped with a pearl nest between the pearl plug once, this time pearl bowl in a bottom relative with following pearl plug along headstock bowl group axially and down the pearl plug direction be set convex with a block at least, this spacing ring is made the hollow ring round, and be pressed and be positioned at down between pearl plug and the front forked frame, it is symmetrical in this time pearl bowl block, at least therein a side periphery is provided with a sliding space, effective argument of this sliding space is equal to or less than 130 degree, and these sliding space both sides respectively are provided with a stop section, borrow these stop sections can limit the anglec of rotation that headstock bowl group is promptly descended the pearl bowl, drive purpose of safety to reach.

Have the baby carrier head bowl group that can limit the anglec of rotation and be elaborated of the present utility model below by most preferred embodiment and accompanying drawing, in the accompanying drawing:

Fig. 1 is existing headstock bowl group generalized section.

Fig. 2 is that the following bowl component of the utility model first preferred embodiment headstock bowl group is separated block diagram.

Fig. 3 is the forward sight combination section of the above-mentioned preferred embodiment of the utility model.

Fig. 4 is the cross-sectional schematic of being got along the straight line 4-4 among Fig. 3.

Fig. 5 is the rotational angle restriction scheme drawing of the above-mentioned preferred embodiment of the utility model.

As Fig. 2, shown in Figure 3, the utility model embodiment has the baby carrier head bowl group that can limit the anglec of rotation, having one, to be set in head tube 200 bottoms be on the front forked frame 300 following bowl group 100, this following bowl group 100 more includes a following pearl bowl 10 that is set in head tube 200 bottoms, one is set in the pearl nest 20 of this time pearl bowl 10 bottoms, one support to end pearl nest 20 bottoms and the following pearl plug 30 and relative with following pearl bowl 10 compel cover be positioned at pearl down fill in 30 and front forked frame 300 between spacing ring 40, and pearl nest 20, the shape of following pearl plug 30, device is for prior art, so no longer describe in detail at this.

This time pearl bowl 10 is to make class's hollow nahlock shape, being symmetrical in head tube 200 axially is to be provided with bowl portion 12 at a sleeve pipe 11 1 ends, and its inside also is provided with symmetrically and is a circular hole 13 and the scrobicular ring 14 that class arranges, this scrobicular ring 14 can be ccontaining for pearl nest 20, and be oppositely directed following bowl portion 12 1 bottoms with sleeve pipe 11, be along following pearl bowl 10 axially and down pearl plug 30 direction be set convex with a block 15.

This spacing ring 40 is to become the hollow ring round with circular plate body punching out, and be pressed and be positioned at down between pearl plug 30 and the front forked frame 300, can rotate with respect to following pearl bowl 10 with the driving of front forked frame 300, it is the block 15 that is symmetrical in this time pearl bowl 10, pearl bowl 10 is provided with the sliding space 41 that direction is extended and respectively be provided with down in peripheral both sides, effective argument of this sliding space 41 is the best with 130 degree, and these sliding space 41 both sides respectively are provided with a stop section 42, in addition, spacing ring 40 end faces that are symmetrical in following pearl bowl 10 wherein a side more be provided with one and indicate mark 43, this sign mark 43 just is positioned at the midway location of two stop sections 42, and is symmetrical in vehicle centre-line or working direction.

As shown in Figure 3, Figure 4, when desiring assembly, be that spacing ring 40, following pearl plug 30, pearl nest 20, following pearl bowl 10 are set on the front forked frame 300 in regular turn, and when making down pearl bowl 10 desires sheathed, indicate the indication of mark 43 earlier according to spacing ring 40 end faces, make that the block 15 of pearl bowl 10 is symmetrical in this sign mark 43 down, can be with block 15 and sliding space 41 fit, assembly mutually easily, and after the headstock bowl is organized whole assembly and is finished, can in 130 degree scopes, rotate by control handle standpipe 400, to reach purpose of safety.

As shown in Figure 5, when operation front forked frame 300 (being stem 400) rotates, can drive spacing ring 40 rotates, utilization is the block 15 of the following pearl bowl 10 of positioning states, then can limit the rotational angle of front forked frame 300, stem 400 and spacing ring 40, reaching the safety that drives, and meet the safety check regulation of perambulator.

What deserves to be mentioned is that block also can be arranged on the spacing ring, stop section and sliding space then can be oppositely arranged on down on the pearl bowl, also can reach identical purpose and effect.
