Abstract

The utility model relates to a baby carriage, comprising side supporting frames and transverse connecting rods, wherein, the side supporting frames are arranged on both sides of the utility model, the side supporting frames are transversely connected with each other through the transverse connecting rods, and each of the side supporting frames comprises an arched base frame (8), a front leg (10), a rear leg (6), an upper connecting rod (2), a front connecting rod (12), a push handspike (3), a rear connecting rod (4), a swing rod (5) and a lower connecting rod (11). The utility model is characterized in that the front end of the lower connecting rod (11) can be rotatablely connected with a point arranged on the upper end of the front leg (10), and the other point arranged on the upper end of the front leg (10) can be rotatablely connected with the lower end of the front connecting rod (12). Dead points are not generated when the utility model is folded or spread.

Description

Perambulator

The utility model relates to a kind of perambulator.

In the prior art, perambulator for example Chinese patent 92215144.x discloses a kind of fold mechanism, this mechanism is made up of arc underframe and foreleg, back leg, front rod, rear linking rod, boxed rod, lower link, the upper end of the leading section of its lower link and the bottom of front rod and foreleg is articulated in a bit, this structure can cause the rod member stack of common hinged place in actual manufacturing process, increase the volume after car body folds.Also having a kind of structure is to be provided with an independent rotation part between described front rod and foreleg, the upper end and the front rod of this tumbler are hinged, the lower end and the foreleg of this tumbler are hinged, the rear end and the lower link of tumbler are hinged, because many tumblers, therefore can cause perambulator when folding or opening, the dead point to occur, can't fold or open at this position, dead point car body.

The purpose of this utility model is to provide a kind of perambulator that does not have the dead point in folding process or opening procedure.

The technical solution of the utility model is: a kind of perambulator comprises the side stand of both sides and the tranverse connecting rod that laterally is connected side stand; Described side stand be the arcuate bottom chord position in the below, the front portion of described arc underframe is provided with can be to the front-wheel support of the top of arc underframe upset, this front-wheel support is provided with rotating front-wheel; The rear portion of described arc underframe is provided with can be to the rear wheel support of the top of arc underframe upset, and this rear wheel support is provided with rotating trailing wheel; The be rotatably connected bottom of foreleg, the front portion of described arc underframe, the be rotatably connected bottom of back leg, the rear portion of described arc underframe, the upper end of described back leg a bit is rotatably connected with the leading section of boxed rod, another point of the upper end of described back leg is rotatably connected with the upper end of front rod, the rearward end of pushing hands bar and boxed rod is rotatably connected, described pushing hands bar extends to form rear linking rod to the be rotatably connected below of portion of pushing hands bar and boxed rod, the upper end of fork and described rear linking rod are rotatably connected, the bottom and the back leg of described fork are rotatably connected, the rearward end of lower link and the bottom of rear linking rod are rotatably connected, the leading section of described lower link and the upper end of foreleg a bit are rotatably connected, and another point of the upper end of described foreleg also is rotatably connected with the bottom of front rod.

The utility model compared with prior art has following advantage:

Be connected owing to become two point of connection by an original point of connection between foreleg, lower link, the front rod, therefore do not increase new rod member, the path of motion of three rod member connections is unique, therefore the dead point phenomenon can not occur.

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

Accompanying drawing 1 is the structural representation of side stand of the present utility model under open mode;

Accompanying drawing 2 is the structural representation of side stand of the present utility model under folded state; Wherein:

[1]. grab rail; [2]. boxed rod; [31. pushing hands bars; [4]. rear linking rod; [5]. fork; [6]. back leg; [7]. trailing wheel; [8]. the arc underframe; [9]. front-wheel; [10]. foreleg; [11]. lower link; [12]. front rod; [13]. front-wheel support; [14]. rear wheel support.

Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, a kind of perambulator comprises the side stand of both sides and the tranverse connecting rod that laterally is connected side stand; Described side stand is that arc underframe [8] is positioned at the below, and the front portion of described arc underframe [8] is provided with can be to the front-wheel support [13] of the top of arc underframe [8] upset, and this front-wheel support [13] is provided with rotating front-wheel [9]; The rear portion of described arc underframe [8] is provided with can be to the rear wheel support [14] of the top of arc underframe [8] upset, and this rear wheel support [14] is provided with rotating trailing wheel [7]; When described front-wheel support [13] and rear wheel support [14] were turned to the top of arc underframe [8], arc underframe [8] landed and makes perambulator to shake.The be rotatably connected bottom of foreleg [10], the front portion of described arc underframe [8], the be rotatably connected bottom of back leg [6], the rear portion of described arc underframe [8], the upper end of described back leg [6] a bit is rotatably connected with the leading section of boxed rod [2], another point of the upper end of described back leg [6] is rotatably connected with the upper end of front rod [12], pushing hands bar [3] is rotatably connected with the rearward end of boxed rod [2], described pushing hands bar [3] extends to form rear linking rod [4] to the be rotatably connected below of portion of pushing hands bar [3] and boxed rod [2], the upper end of fork [5] and described rear linking rod [4] are rotatably connected, the bottom of described fork [5] and back leg [6] are rotatably connected, the bottom of the rearward end of lower link [11] and rear linking rod [4] is rotatably connected, the upper end of the leading section of described lower link [11] and foreleg [10] a bit is rotatably connected, and another point of the upper end of described foreleg [10] also is rotatably connected with the bottom of front rod [12].Referring to accompanying drawing 1, described foreleg [10], front rod [12], boxed rod [2] present one the arc of projection forward successively continuously.The bottom portion of being rotatably connected of the upper end of described foreleg [10] and front rod [12] is positioned at the described preceding outside of the arc of projection forward.
