Abstract
The utility model provides a connector between a tractor and a trailer hook and belongs to the technical field of connectors. One side of the closed end of the duckbill-shaped hook is hinged to a connecting block through a rotating shaft. The connecting block is provided with a through hole in the perpendicular direction. Pin holes are formed in one side of the open end of the duckbill-shaped hook. A hinge pin is arranged in the pin holes. According to the connector between the tractor and the trailer hook, it means that a cardan joint is additionally arranged between the tractor and a trailer, so that flexible connection between the tractor and the trailer is achieved; in this way, when the tractor and the trailer run on a rugged road or the edge of a field with a violently changing gradient, the rear trailer cannot lift the tractor any longer, and therefore traffic safety is guaranteed. Even if the tractor pulls the trailer to turn a small corner, rear wheels of the tractor cannot generate friction with the connector between the tractor and the trailer hook or the trailer, and therefore normal running of the vehicles is guaranteed.
Description
Technical field
The utility model relates to the adaptor union between a kind of trac. and hook attachment for trailer, belongs to connector technique field.
Background technology
It is direct coupled by pin that existing trac. duckbill is below linked up with between trailer connector, connect (see figure 1) also referred to as " firmly ", such type of attachment, it is no problem that trac. and trailer travel on highway or on more smooth secondary road.If but while travelling on rugged road or on the field of gradient big rise and fall, trailer below can stick up trac., makes the wheelie of trac., and at this moment roll-over accident very easily occurs, and even causes casualties.More again, when trac. turns littlely when curved, the trailing wheel of trac. is easy to friction on trailer connector or trailer, causes trac. load to strengthen or flame-out.
Summary of the invention
The purpose of this utility model is the problem existing in order to solve above-mentioned prior art, if while travelling on rugged road or on the field of gradient big rise and fall, trailer below can stick up trac., make the wheelie of trac., at this moment very easily there is roll-over accident, even cause casualties.More again, when trac. turns littlely when curved, the trailing wheel of trac. is easy to friction on trailer connector or trailer, causes trac. load to strengthen or flame-out.And then provide the adaptor union between a kind of trac. and hook attachment for trailer.
The purpose of this utility model is achieved through the following technical solutions:
Adaptor union between a kind of trac. and hook attachment for trailer, comprise: contiguous block, rotating shaft, duckbill hook and bearing pin, closed end one side and the contiguous block of described duckbill hook are hinged by rotating shaft, on contiguous block, have the through hole of a vertical direction, open end one side of duckbill hook is provided with pin-and-hole, and bearing pin is arranged in described pin-and-hole.
Adaptor union between trac. of the present utility model and hook attachment for trailer, be equivalent to add a universal-joint between trac. and trailer, " soft " of having realized between trac. and trailer is connected, while making trac. and trailer travel on rugged road or on the field of gradient big rise and fall, or else trailer below also can stick up trac., has ensured traffic safety.Even if tractor traction trailer turns the little curved trailing wheel that also can not make trac. and rubs on trailer connector or trailer, ensure normally travelling of vehicle.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: the present embodiment is implemented under taking technical solutions of the utility model as prerequisite, has provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figures 2 and 3, adaptor union between a kind of trac. and hook attachment for trailer that the present embodiment is related, comprise: contiguous block 1, rotating shaft 3, duckbill hook 4 and bearing pin 5, closed end one side and the contiguous block 1 of described duckbill hook 4 are hinged by rotating shaft 3, on contiguous block 1, have the through hole 2 of a vertical direction, open end one side of duckbill hook 4 is provided with pin-and-hole 9, and bearing pin 5 is arranged in described pin-and-hole 9.
When use, contiguous block 1 is inserted in the duckbill hook of existing trac., is plugged with pin, then trailer connector is inserted in the duckbill hook 4 of the present embodiment, be plugged and get final product breakdown trailer (also claiming trailer) upper track with bearing pin 5.
As shown in Figure 4 and Figure 5, further, also comprise two U-shaped arms 6, two back-moving springs 7 and two axle beds 8, described two axle bed 8 symmetries are fixed on the both sides outer wall of contiguous block 1, each axle bed 8 is provided with a U-shaped arm 6, U-shaped arm 6 is hinged with axle bed 8, between two U-shaped arms 6, be provided with two back-moving springs 7, a back-moving spring 7 is arranged between two U-shaped arms 6 on contiguous block 1 top, a back-moving spring 7 is arranged between two U-shaped arms 6 of contiguous block 1 bottom, and 4 both sides frictional connection is linked up with respectively in circular arc one end of two U-shaped arms 6 with duckbill.
Two U-shaped arms 6 are to clamp duckbill hook 4 by the power of upper and lower two back-moving springs 7, and its Main Function is to allow duckbill hook 4 be in arbitrarily angled going up, instead of sagging, is convenient to like this trailer connector to dock with it.
The above; it is only preferably detailed description of the invention of the utility model; these detailed description of the invention are all the different implementations based under the utility model general idea; and protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
