Abstract
A bicycle trailer used concurrently as a trammer comprises a trailer frame[4], a pair of rear wheels[5] arranged under the trailer frame[4], a push rod[3] arranged on the rear of the trailer frame[4], a draw bar[8]. The bicycle trailer is characterized in that: the draw bar is set at least two work positions, the first work position is a drawing work position that the front of the draw bar[8] stretches forwards, while the second work position is a folding work position that the draw bar[8] folds backwards relative to the trailer frame[4]. When the draw bar locates on the second work position, a wheel frame shaft[9] locates approximately the central anterior position between the two rear wheels[5]. When the utility model is separated from a bicycle, the trailer is convenient to operation used as a trammer.
Description
The utility model relates to a kind of trailer of bicycle.
In the prior art, trailers comprises trailer chassis, be arranged at the pair of rear wheels of the below of described trailer chassis, be arranged at pushing hands bar, the draw bar at described trailer chassis rear portion, the leading section of described draw bar is provided with and is used for the hitch head that is connected with bicycle, the rear portion of described draw bar and described trailer chassis flexibly connect, also be connected with the front-wheel wheel carrier on the described draw bar, on the described front-wheel wheel carrier front-wheel be housed by wheel carrier rotating shaft longitudinally.Described draw bar is when folding is used as go-cart backward, and front-wheel deviates from the front, center position of two trailing wheels, and the instability of go-cart this moment also is difficult to stablize its sense of motion during go-cart.
The purpose of this utility model is to provide a kind of can doublely do the trailers that go-cart is used, and is convenient to handle its sense of motion when using as go-cart.
The technical solution of the utility model is: can doublely do the trailers that go-cart is used, comprise trailer chassis, be arranged at the pair of rear wheels of the below of described trailer chassis, be arranged at the pushing hands bar at described trailer chassis rear portion, draw bar, the leading section of described draw bar is provided with and is used for the hitch head that is connected with bicycle, the rear portion of described draw bar and described trailer chassis flexibly connect, also be connected with the front-wheel wheel carrier on the described draw bar by wheel carrier rotating shaft longitudinally, on the described front-wheel wheel carrier front-wheel is housed, described draw bar has two control positioies at least, and first control position is the traction control position that stretch forward the front portion of draw bar; Second control position is a draw bar with respect to trailer chassis's folding control position of folding backward, this moment draw bar another place by locking mutually between lockout mechanism and the trailer chassis; Be under described second control position at draw bar, described wheel carrier rotating shaft is the central anterior position between two trailing wheels haply.
The utility model compared with prior art has following advantage:
When using as go-cart, the wheel carrier rotating shaft is the central anterior position between two trailing wheels haply, this moment, draw bar locked mutually with trailer chassis, therefore constitute an equicrural triangle between the touchdown point of front-wheel and two trailing wheels, roughly the same with the structure of existing three-wheel vehicle, therefore control comfort can use when the utility model and the disengaging of bicycle car.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is the structural front view of the utility model when using as go-cart; The constitution diagram (draw bar is in first control position) that bar and front-wheel use during as trailer of representing to pull strings of long and two-short dash line wherein;
The structure birds-eye view of (draw bar is in second control position) when accompanying drawing 2 uses as go-cart for the utility model; Structural representation when long and two-short dash line wherein represents that draw bar is positioned at first control position; Wherein:
[1], front-wheel; [2], front-wheel wheel carrier; [3], pushing hands bar; [4], trailer chassis; [5], trailing wheel; [6], hitch head; [7], lockout mechanism; [8], draw bar; [9], wheel carrier rotating shaft;
Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, a kind of trailers that can doublely do the go-cart use, comprise trailer chassis [4], be arranged at the pair of rear wheels [5] of the below of described trailer chassis [4], be arranged at the pushing hands bar [3] at described trailer chassis [4] rear portion, draw bar [8], the leading section of described draw bar [8] is provided with and is used for the hitch head [6] that is connected with bicycle, the rear portion of described draw bar [8] and described trailer chassis [4] flexibly connect, also be connected with front-wheel wheel carrier [2] on the described draw bar [8] by wheel carrier rotating shaft longitudinally [9], front-wheel [1] is housed on the described front-wheel wheel carrier [2], and described draw bar [8] has two control positioies at least.Referring to the draw bar that the long and two-short dash line of accompanying drawing 1 and accompanying drawing 2 is represented, first control position is the traction control position that stretch forward the front portion of draw bar [8], and hitch head this moment [6] is connected with the rear portion of bicycle, and bicycle can drive this practicality and move.Referring to the draw bar that the solid line of accompanying drawing 1 and accompanying drawing 2 is represented, second control position is a draw bar [8] with respect to trailer chassis [4] the folding control position of folding backward, and another place of draw bar this moment [8] locks mutually by between lockout mechanism [7] and the trailer chassis [4].Described lockout mechanism [7] can be the snap close that is arranged in the trailer chassis [4], the relative locking with trailer chassis [4] of draw bar [8], makes draw bar [8] can not move with respect to trailer chassis [4] when it hooks on the draw bar [8]; Be under described second control position at draw bar, described wheel carrier rotating shaft [9] is positioned at the central anterior position between two trailing wheels [5] haply.The rear portion of described draw bar [8] and described trailer chassis [4] are hinged.
Claims (2)
