Abstract

The utility model relates to a reversible handle handcart comprising a front leg (10), a rear leg (4), a seat pad rod (9) and a plurality of folding connection rods (5); a seat pad is arranged on the seat pad rod (9). The utility model is characterized in that a bent section (12) of the bent rear leg is arranged at the upper part of the rear leg (4); the bent section (12) of the bent rear leg is pivoted with a reversible connection rod (11); the lower part of the reversible connection rod (11) is pivoted with the upper end part of the front leg (10); the lower part of a push rod (2) is rotatablely connected with the reversible connection rod (11); the push rod (2) has two reversible work positions. The upper part of the rear leg is provided with a bent section of the bent rear leg, which is convenient in connecting of the push rod and a whole handcart body in reversing. The reversing of the posh rod is reliable and has no influence on the folding of the handcart.

Description

The commutation type umbrella handle vehicle

The utility model relates to a kind of umbrella handle vehicle.

In the prior art, umbrella handle vehicle, comprise foreleg, be arranged at foreleg below front-wheel, back leg, the trailing wheel that is arranged at described back leg below, anterior and foreleg is rotatably connected and seat cushion bar that rear portion and back leg are rotatably connected, be arranged at many folding connecting rods on described foreleg and the back leg, described seat cushion bar is provided with seat cushion, the bottom of the back support bar that also is rotatably connected on the described seat cushion bar; Pushing hands bar and foreleg are hinged, when folding baby carrier, relatively rotate between pushing hands bar and the foreleg, make perambulator horizontal and vertical folding simultaneously, the perambulator of this structure can not commutate, and when go-cart person uses, can't be aspectant state with the baby, and have only the state of facing the back of the body, therefore can't in time observe the baby.

The purpose of this utility model is to provide a kind of commutation type umbrella handle vehicle that can commutate to the pushing hands bar.

The technical solution of the utility model is: a kind of commutation type umbrella handle vehicle, comprise foreleg, be arranged at foreleg below front-wheel, back leg, the trailing wheel that is arranged at described back leg below, anterior and foreleg is rotatably connected and seat cushion bar that rear portion and back leg are rotatably connected, be arranged at many folding connecting rods on described foreleg and the back leg, described seat cushion bar is provided with seat cushion, the bottom of the back support bar that also is rotatably connected on the described seat cushion bar; The top of back leg is provided with the back leg bending section of bending, and the second turning cylinder pivotal joint is passed through with the top of commutation connecting rod in the front portion of this back leg bending section, and the bottom of commutation connecting rod and the upper end of described foreleg are by the first turning cylinder pivotal joint; Bottom and described commutation connecting rod that the top has the pushing hands bar of handgrip are rotatably connected, described pushing hands bar has two control positioies, first control position is that described pushing hands bar and described foreleg are the almost parallel setting, locks by blocking device between described pushing hands bar and the described commutation connecting rod; Second control position is that described pushing hands bar and described back leg bending section are the almost parallel setting, locks by blocking device between described pushing hands bar and the described back leg bending section.

The utility model compared with prior art has following advantage:

Because the top of back leg is provided with the back leg bending section of bending, be connected with whole locomotive body when therefore being convenient to the commutation of pushing hands bar, the commutation of pushing hands bar is reliable, and does not influence the folding of go-cart.

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

Accompanying drawing 1 is a front view of the present utility model, the state after wherein long and two-short dash line is represented to commutate;

Accompanying drawing 2 is the three-dimensional structure diagram of vehicle frame of the present utility model;

Cutaway view when accompanying drawing 3 is connected with blocking device for pushing hands bar commutation back; Wherein: [1], handgrip; [2], pushing hands bar; [3], back support bar; [4], back leg; [5], back folding connecting rod; [6], trailing wheel; [7], front-wheel; [8], following cross connecting rod; [9], seat cushion bar; [10], foreleg; [11], commutation connecting rod; [12], back leg bending section; [13], first turning cylinder; [14], second turning cylinder; [15], spring; [16], contiguous block; [17], trailing cable; [18], handle; [19], first lock slots; [20], second lock slots;

Embodiment: a kind of commutation type umbrella handle vehicle, comprise foreleg [10], be arranged at front-wheel [7], the back leg [4] of foreleg [10] below, the trailing wheel [6] that is arranged at described back leg [4] below, anterior being rotatably connected and seat cushion bar [9] that rear portion and back leg [4] are rotatably connected, be arranged at the many folding connecting rods [5] on described foreleg [10] and the back leg [4] with foreleg [10], described seat cushion bar [9] is provided with seat cushion, the bottom of back support bar [3] that also are rotatably connected on the described seat cushion bar [9]; It more than is the structure of existing umbrella handle vehicle.Referring to accompanying drawing 1, characteristic of the present utility model is: the top of back leg [4] is provided with the back leg bending section [12] of bending, second turning cylinder [14] pivotal joint is passed through with the top of commutation connecting rod [11] in the front portion of this back leg bending section [12], and the bottom of commutation connecting rod [11] and the upper end of described foreleg [10] are by first turning cylinder [13] pivotal joint; Bottom and described commutation connecting rod [11] that the top has the pushing hands bar [2] of handgrip [1] are rotatably connected, described pushing hands bar [2] has two control positioies, first control position is that described pushing hands bar [2] is the almost parallel setting with described foreleg [10], locks by blocking device between described pushing hands bar [2] and the described commutation connecting rod [11]; Second control position is that described pushing hands bar [2] is the almost parallel setting with described back leg bending section [12], locks by blocking device between described pushing hands bar [2] and the described back leg bending section [12].

Blocking device certainly also has the blocking device of other structure referring to accompanying drawing 3.In the accompanying drawing 3, handle [18] pulling trailing cable [17] drives contiguous block [16], makes contiguous block break away from first lock slots [19], and then pushing hands bar [2] can commutate, commutation back contiguous block [16] enters second lock slots [20] that is positioned on the back leg bending section [12], and then the locking of commutation back finishes.
