Description
Technical field
The utility model relates to a kind of folding children's barrow particularly can be laterally folded or the preceding armrest mechanism of bi-directional folded children trolley.
Background technology
In existing children and/or the doll carriage product, preceding armrest mechanism has multiple.Wherein a kind of is that preceding handrail directly is fixed on the front-wheel support, can not fold, and the packaging volume of go-cart is bigger.In order to reduce packaging volume, occurred preceding handrail by rotating shaft and the front-wheel support armrest before the bonded assembly that rotates, the preceding handrail of this children trolley, though can be folded, but it need will carry out manually folding or opening operation separately to preceding handrail, operation inconvenience when folding or expansion.
China utility model patent CN 201472448U discloses a kind of preceding armrest mechanism of doll carriage, it comprises front-wheel support, push rod and preceding handrail, wherein the two ends of preceding handrail are fixedly connected with preceding armrest seat respectively, be mounted with permanent seat on the push rod, preceding armrest seat rotates by rotating shaft with permanent seat and is connected, one side of permanent seat is provided with locating part, preceding armrest seat is provided with the arc position-limited trough with the circumferential bearing fit of locating part, when go-cart is in open mode, locating part pushes against end at the arc position-limited trough with the angle locking between handrail before realizing and the push rod, so, when go-cart folds, resupinate can the drive simultaneously on the preceding handrail of front-wheel support turned over, need not the separately manual folding operation of preceding handrail, yet the preceding handrail of this preceding armrest mechanism can not be laterally folded, thereby when go-cart was laterally folded go-cart or bi-directional folded go-cart, this preceding armrest mechanism can have influence on the folding of go-cart or increase the folding volume of go-cart.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of be particularly suitable for can be laterally folded children trolley and the preceding armrest mechanism of bi-directional folded children trolley, it can participate in the auto-folder of go-cart vehicle frame, and takes the folding volume of children trolley of this preceding armrest mechanism little.
For solving above technical matters, the utility model is taked following technical scheme:
A kind of preceding armrest mechanism of horizontal folding children's barrow, comprise preceding handrail, be used for preceding handrail is installed in permanent seat on the side stand of children trolley, handrail is formed by first rotating shaft, two the second handrail sections of bonded assembly that rotate by the first handrail section and with the two ends of the first handrail section before described, preceding armrest mechanism also comprises the sheath on the outer end that is set in the second handrail section, be connected the outer end of the second handrail section and the Connection Block between the permanent seat, one end of this Connection Block rotates by second rotating shaft with the outer end of the second handrail section and is connected, the other end rotates by the 3rd rotating shaft with permanent seat and is connected, and first rotating shaft, the axial line of second rotating shaft is all perpendicular with the axial line of the 3rd rotating shaft, between permanent seat and Connection Block, be provided with and be used to make that Connection Block has the torsion spring of the trend of upwards overturning, armrest mechanism also comprises the lockout mechanism that is used for preceding armrest mechanism is locked in deployed condition before described, described lockout mechanism comprises the locked groove that is opened on the sheath, be arranged on the lock dog in the permanent seat versatilely and make lock dog have the elastic component of the trend in the locked groove that remains on, when described lockout mechanism is in the lock state, the part of described lock dog is stuck in the locked groove, and when the side stand that carries out children trolley was laterally folded, the outer end of the second handrail section promoted lock dog and breaks away from locked groove and realize release.
According to the utility model, described permanent seat can be fixedly mounted on the seat bar or front-wheel support of side stand, on the preferred fixing present bar.
A concrete aspect according to the utility model lockout mechanism, described lock dog can be provided with movably along the direction vertical with the 3rd rotating shaft, it has the cooperation inclined-plane that is positioned at locked groove when lock-out state, when children trolley was carried out laterally folded operation, the second handrail section cooperated the promotion lock dog to break away from locked groove with cooperating the inclined-plane.
Preferably, described lock dog also has after cooperating the inclined-plane and the second handrail section to break away from and the guiding surface of Connection Block mating reaction.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
1, handrail is rotated by the first handrail section and two second handrail sections and connects and composes before of the present utility model, and two second handrail sections can be rotated and folding reduces horizontal volume to the centre; In addition, preceding handrail is connected on the side stand by Connection Block and permanent seat, and Connection Block can be around the upwards upset of rotating shaft of itself and permanent seat, thereby the upset of handrail is folding before realizing, therefore, adopts children trolley of the present utility model, car load is folding in good order, and packing measurements is little.
2, the utility model is installed on the side stand, laterally folded along with the go-cart vehicle frame, and the lockout mechanism automatic unlocking of preceding armrest mechanism, laterally folding earlier, under the effect of torsion spring, upwards upset automatically realizes that upset is folding, need not manually operation separately then.
