The mounting bracket stated is equipped with the directive wheel for drawstring guiding, and the directive wheel is located along the same line with spring assembly；
The connecting rod limiting slot for one end limition orientation connecting for connecting rod with drawstring is additionally provided in the mounting bracket.
Include: to the technical solution that the utility model is further qualified
The spring assembly includes the pull rod connecting with drawstring, the reset spring that driving pull rod resets, reset spring
One end connect with mounting bracket, the other end is connect with pull rod.
The mounting bracket is equipped with spring mounting seat, is equipped with through-hole among spring mounting seat, and the one of the pull rod
End is equipped with presenting a theatrical performance as the last item on a programme for compressed spring, and the other end of pull rod passes through through-hole and connect with drawstring, and the reset spring position is arranged
On pull rod, and between being located at spring mounting seat and presenting a theatrical performance as the last item on a programme.
One end that the connecting rod is connect with drawstring is equipped with the pulley being placed in connecting rod limiting slot.
The damping block of friction fit is equipped between the connecting rod and mounting bracket.
Through the above technical solutions, the utility model has the following beneficial effects: the company of the structure of tow line hinge of the utility model
Between bar and spring assembly by drawstring be flexibly connected, mounting bracket be equipped with for rope guiding directive wheel, directive wheel with
Spring assembly is located along the same line, to keep the direction of pull of spring constant always, and mounting bracket is equipped with and is used for pull rod
The connecting rod limiting slot of limition orientation, to guarantee that swing arm can be along the either on or off of set angle steady and smooth.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model structure of tow line hinge.
Fig. 2 is the schematic perspective view of the utility model structure of tow line hinge.
Fig. 3 is the configuration schematic diagram of the utility model structure of tow line hinge.
Specific embodiment
It is described further below in conjunction with structure of the attached drawing to the utility model.
Referring to figs. 1 to Fig. 3, the structure of tow line hinge of the utility model includes mounting bracket 1, hinged with mounting bracket
Swing arm 2, and driving swing arm and mounting bracket rotate the swing arm resetting-mechanism 3 closed, and mounting bracket 1 and swing arm 2 pass through first
Hinged shaft 11 is hinged.Swing arm resetting-mechanism 3 includes connecting rod 31, and one end of connecting rod and swing arm are hinged, and the other end of connecting rod is connected with
Drawstring 32, connecting rod and swing arm are hinged by the second hinged shaft 12.Swing arm resetting-mechanism further includes having driving drawstring to pull link rotatable
The spring assembly 33 for driving swing arm to reset, mounting bracket 1 are equipped with the directive wheel 34 for drawstring guiding, directive wheel and groups of springs
Part is located along the same line；The connecting rod limit for one end limition orientation connecting for connecting rod with drawstring is additionally provided in mounting bracket 1
Slot 35.In the present embodiment, one end that connecting rod is connect with drawstring is equipped with the pulley 36 being placed in connecting rod limiting slot.When swing arm is swung,
