CN2389095Y - Umbrella shaped handle cart - Google Patents

Abstract

The utility model relates to an umbrella-shaped handle cart comprising front legs (3), a front wheel (4), rear legs (8), a rear wheel (7), push rods (1), a lower cross support device (5) which are respectively and rotatablely connected with a pair of front legs (3) and a pair of rear legs (8); the rear cross support device (9) which are respectively and rotatablely connected with two rear connection rods (10) and a pair of push rods (1). The utility model is characterized in that the front end part of a lower connection rod (6) is rotatablely connected with the front legs (3); the rear end part of the lower connection rod (6) is rotatablely connected with the rear leg (8). The rigid of the utility model is improved; when a base pad rod is stressed to press downward, the inward bent degree of the front and the rear legs become small; wheel axles of the front wheel and the rear wheel are basically kept in horizontal direction.

Description

Umbrella handle vehicle

The utility model relates to a kind of perambulator.

In the prior art, a kind of umbrella handle vehicle, comprise foreleg, be arranged at the rotating front-wheel of described foreleg bottom, back leg, be arranged at the rotating trailing wheel of the bottom of described back leg, the pushing hands bar that the rearward end of leading section and described foreleg is rotatably connected, the upper end of described back leg and described pushing hands bar are rotatably connected, two leading sections of the following cross that two rod members intersect and are rotatably connected at infall are rotatably connected with the bottom of a pair of foreleg respectively, two rearward end of described cross down respectively with described a pair of back leg or a pair of back leg on tumbler be rotatably connected; The outer end of two rear linking rods respectively with a pair of back leg or back leg on tumbler be rotatably connected, be rotatably connected between the inner end of described two rear linking rods and be provided with inhibiting device at its place of being rotatably connected; Two rod members intersect and are rotatably connected with the outer end of two rear linking rods or the tumbler on the back leg respectively in two bottoms of the back cross that infall is rotatably connected, and two upper ends of described back cross are rotatably connected with a pair of pushing hands bar respectively; Described pushing hands bar is provided with the seat cushion bar, and described seat cushion bar is provided with seat cushion; Because umbrella handle vehicle can lateral contraction fold, so only be provided with tranverse connecting rod at the rear portion of vehicle frame, all the other places only depend on down cross and back cross to support, with foreleg, back leg, pushing hands bar serves as that the main side stand rigidity of forming is bad, because the seat cushion on the seat cushion bar is subjected to downward pressure after the baby takes, drive the foreleg of both sides and back leg to the center direction bending, the wheel shaft that can cause front-wheel and trailing wheel makes when promoting umbrella handle vehicle that wheel turns is smooth even can not rotate not in horizontal direction.

The purpose of this utility model is to provide a kind of umbrella handle vehicle with better rigidity.

The technical solution of the utility model is: a kind of umbrella handle vehicle, comprise foreleg, be arranged at the rotating front-wheel of described foreleg bottom, back leg, be arranged at the rotating trailing wheel of the bottom of described back leg, the pushing hands bar that the rearward end of leading section and described foreleg is rotatably connected, the upper end of described back leg and described pushing hands bar are rotatably connected, two leading sections of the following cross that two rod members intersect and are rotatably connected at infall are rotatably connected with the bottom of a pair of foreleg respectively, two rearward end of described cross down respectively with described a pair of back leg or a pair of back leg on tumbler be rotatably connected; The outer end of two rear linking rods respectively with a pair of back leg or back leg on tumbler be rotatably connected, be rotatably connected between the inner end of described two rear linking rods and be provided with inhibiting device at its place of being rotatably connected; Two rod members intersect and are rotatably connected with the outer end of two rear linking rods or the tumbler on the back leg respectively in two bottoms of the back cross that infall is rotatably connected, and two upper ends of described back cross are rotatably connected with a pair of pushing hands bar respectively; Described pushing hands bar is provided with the seat cushion bar, and described seat cushion bar is provided with seat cushion; The leading section of lower link and described foreleg are rotatably connected, and are rotatably connected between the rearward end of described lower link and the described back leg.

The utility model compared with prior art has following advantage:

Owing to increased lower link, be under the state of opening at umbrella handle vehicle, form a stable triangle by lower link, foreleg, back leg, pushing hands bar, make side stand can not be out of shape, the rigidity of whole car is improved, present lining bar stressed when pressing down the sinuousness to the inside of foreleg, back leg little, the wheel shaft of front-wheel and trailing wheel keeps horizontal direction substantially.

The utility model will be further described below in conjunction with drawings and Examples:
