Abstract

A children pushchair is provided, comprising a front wheel bracket [1], a front wheel [14], a rear wheel bracket [8], a rear wheel [15], a lower linking [2], a hand pushing pole [6] and a front arm-rest [4], and the upper end part of the front wheel bracket [1] is fixed with a pushing pole connecting piece [3], and the lower end part of the hand pushing pole [6] is in pivot joint with the pushing pole connecting piece [3], and the hand pushing pole [6] is provided with an arm-rest fixing piece [12], and the front arm-rest [4] is provided with a arm-rest connecting piece [13], when the pushchair is in an unfolding condition, the B plane of the front and lower part of the arm-rest connecting piece [13] contacts the K plane of the back and upper part of the pushing pole connecting piece [3]. In the utility model, small linking is left out, so that the construction of the pushchair body is simple, and the production cost is reduced.

Description

Children trolley

Technical field

The utility model relates to a kind of perambulator.

Background technology

In the prior art, children trolley, comprise front-wheel support, be arranged at the front-wheel of front-wheel support below, rear wheel support, be arranged at the trailing wheel of rear wheel support below, front and rear respectively with the lower link of front-wheel support and rear wheel support pivotal joint, the pushing hands bar of the upper end pivotal joint of bottom and front-wheel support, be arranged at the preceding handrail on the described pushing hands bar, the upper end of described front-wheel support is fixed with the push rod attaching parts, the bottom of described pushing hands bar is connected with push rod attaching parts phase pivot, be fixed with the handrail connecting element on the described pushing hands bar, be fixed with the handrail attaching parts on the handrail before described, pivotal joint and be provided with rotating and limiting mechanism between handrail attaching parts and the handrail connecting element, between preceding handrail and front-wheel support, also be provided with a small rod, when go-cart folded, handrail can rotate counterclockwise before this small rod made.But the existence of this small rod makes whole cart increase, and it is big that the correlativity of rod member becomes, and this small rod makes that also the moulding of car load is not attractive in appearance.

Summary of the invention

The purpose of this utility model is to provide a kind of children trolley simple in structure.

The technical solution of the utility model is: a kind of children trolley, comprise front-wheel support, be arranged at the front-wheel of front-wheel support below, rear wheel support, be arranged at the trailing wheel of rear wheel support below, front and rear respectively with the lower link of front-wheel support and rear wheel support pivotal joint, the pushing hands bar of the upper end pivotal joint of bottom and front-wheel support, be arranged at the preceding handrail on the described pushing hands bar, the upper end of described front-wheel support is fixed with the push rod attaching parts, the bottom of described pushing hands bar is connected with push rod attaching parts phase pivot, be fixed with the handrail connecting element on the described pushing hands bar, be fixed with the handrail attaching parts on the handrail before described, pivotal joint and be provided with rotating and limiting mechanism between handrail attaching parts and the handrail connecting element, under go-cart was in open mode, the B plane of the preceding bottom of described handrail attaching parts contacted with the K plane of push rod attaching parts upper back.

The utility model compared with prior art has following advantage:

Contact with the K plane by the B plane, make go-cart under open mode before handrail can not clockwise direction rotate, and rotating and limiting mechanism make before handrail can not anticlockwise motion, therefore before handrail be in stable mode of operation.And when go-cart was folding, pushing hands bar and front-wheel support relatively rotated, and then throw off mutually with the K plane on the B plane, and car body can fold.The utility model has omitted small rod, makes body Structure simple, and productive costs reduces.

Wherein: [1], front-wheel support; [2], lower link; [3], push rod attaching parts; [4], preceding handrail; [5], handrail connecting element positioning teeth; [6], pushing hands bar; [7], back support bar; [8], rear wheel support; [9], guide groove; [10], torsion spring; [11], handrail attaching parts positioning teeth; [12], handrail connecting element; [13], handrail attaching parts; [14], front-wheel; [15], trailing wheel;

The specific embodiment

Referring to accompanying drawing 1, a kind of children trolley, comprise front-wheel support [1], be arranged at the front-wheel [14] of front-wheel support [1] below, rear wheel support [8], be arranged at the trailing wheel [15] of rear wheel support [8] below, front and rear respectively with the lower link [2] of front-wheel support [1] and rear wheel support [8] pivotal joint, the pushing hands bar [6] of the upper end pivotal joint of bottom and front-wheel support [1], be arranged at the preceding handrail [4] on the described pushing hands bar [6], the upper end of described front-wheel support [1] is fixed with push rod attaching parts [3], the bottom of described pushing hands bar [6] is connected with push rod attaching parts [3] phase pivot, be fixed with handrail connecting element [12] on the described pushing hands bar [6], be fixed with handrail attaching parts [13] on the handrail [4] before described, pivotal joint and be provided with rotating and limiting mechanism between handrail attaching parts [13] and the handrail connecting element [12], this rotating and limiting mechanism arrives shown in the accompanying drawing 7 referring to accompanying drawing 2, be by the handrail attaching parts positioning teeth [11] that is arranged on the handrail attaching parts [13], handrail connecting element positioning teeth [5] dislocation that is arranged on the handrail connecting element [12] involutes, under the state shown in the accompanying drawing 2, handrail attaching parts positioning teeth [11], inconsistent between the handrail connecting element positioning teeth [5], therefore handrail [4] can not contraryly be crossed the rotation of pin direction before, and under the state shown in the accompanying drawing 3, preceding handrail [4] can be rotated in a clockwise direction, at this moment guide groove [9], connecting element positioning teeth [5] slide relative.

Referring to accompanying drawing 2 under go-cart is in open mode, the B plane of the preceding bottom of described handrail attaching parts [13] contacts with the K plane of push rod attaching parts [3] upper back, preceding handrail [4] can not rotate by clockwise direction, because inconsistent between handrail attaching parts positioning teeth [11], the handrail connecting element positioning teeth [5], therefore preceding handrail [4] can not contraryly be crossed the pin direction and rotate.Preceding handrail [4] is positioned.

When folding, to shown in the accompanying drawing 4, because pushing hands bar [6] rotates around push rod attaching parts [3], so the B face on the handrail attaching parts leaves the K face on the push rod attaching parts as accompanying drawing 3, and preceding handrail [4] gets final product clickwise, makes vehicle frame successfully folding.

On the rotation pivot between handrail attaching parts [13] and the handrail connecting element [12], be with torsion spring [10], one end of this torsion spring [10] is fixed on the handrail attaching parts [13], the other end of torsion spring [10] is fixed on the handrail connecting element [12], and this torsion spring [10] is identical to the suffered gravity direction of preceding handrail [4] applied force and the front end of preceding handrail.By folding when entering open mode, the torsion of torsion spring [10] and before the suffered gravity of handrail [4] make before handrail [4] left-hand revolution, open and put in place.
