Description
Technical field
The utility model relates to crank handle device field, particularly relates to a kind of handlebar mechanism.
Background technology
Trailer, unwheeling and other lifting structures complete horizontal or vertical mobile time, all need handlebar mechanism to operate; We devise a kind of handlebar mechanism for this reason.
Summary of the invention
The operation of the utility model conveniently trailer, unwheeling and other lifting structures, and a kind of handlebar mechanism is provided.
The utility model for achieving the above object, there is provided a kind of handlebar mechanism, comprise clamp, lower clamp, screw, bearing pin, packing ring, split pin, taper bolt and No. two screws, upper clamp and lower clamp front end are interspersed with nut, nut three screws are fixed, and nut overcoat has ratchet; The ratchet that ratchet side is provided with and coordinates with it, ratchet bearing pin is fixed, and bearing pin is connected with packing ring and split pin in one end of upper clamp, and ratchet side is provided with ejector pin, and ejector pin is connected with spring; Upper clamp and lower clamp rear end are provided with hand handle; Ejector pin and spring both sides are fixed No. two screws and a pair taper bolt with two.
A described screw and No. two screws are yi word pattern screw.
The beneficial effects of the utility model are: a kind of handlebar mechanism described in the utility model uses very convenient, can be widely used in trailer, unwheeling and other lifting structures.

Embodiment
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
A kind of handlebar mechanism, comprise clamp 2, lower clamp 1, screw 5, bearing pin 7, packing ring 8, split pin 9, taper bolt 13 and No. two screws 14, upper clamp 2 and lower clamp 1 front end are interspersed with nut 4, and nut 4 three screws 5 are fixed, and nut 4 overcoat has ratchet 3; The ratchet 6 that ratchet 3 side is provided with and coordinates with it, ratchet 6 bearing pin 7 is fixed, and bearing pin 7 is connected with packing ring 8 and split pin 9 in one end of upper clamp 2, and ratchet 6 side is provided with ejector pin 10, and ejector pin 10 is connected with spring 11; Upper clamp 2 and lower clamp 1 rear end are provided with hand 12; Ejector pin 10 and spring 11 both sides are fixed No. two screws 14 and a pair taper bolt 13 with two.
A described screw 5 and No. two screws 14 are yi word pattern screw.
Handlebar mechanism is arranged on elevating mechanism, controls the lifting of elevating mechanism.The mode implemented is: rotate hand 12, spring 11 withstands ejector pin 10, ejector pin 10 withstands ratchet 6, whole handlebar mechanism can be controlled by stirring ratchet 6, rotate handlebar mechanism when ratchet 6 is in side and can only control elevating mechanism rising, rotating handlebar mechanism when ratchet 6 is at opposite side can only make elevating mechanism decline, thus realizes the effect of the rise and fall being controlled elevating mechanism by handlebar mechanism.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
