Abstract
The utility model relates to a double-bent tube frame for a manpower tricycle, which is convenient for getting on or getting off a bicycle, has big supporting strength and can be used firmly and durably. The utility model comprises a three-way vertical tube, a lower oblique beam, a five-way casing tube, a rear seat vertical tube, a bicycle rear bottom frame and a rear fork, which form a bicycle body basic frame, and an upper curved beam with symmetrical front and back parts are welded between the three-way vertical tube and the back fork.
Description
The utility model relates to a kind of manual tricycle double bent tube vehicle frame.
Existing manual tricycle has mainly contained straight beam and two kinds of structures of camber beam, and straight beam structure is straight beam of welding between vertical tube threeway and back seat standpipe, and its advantage is that stress point is a triangle, and bearing strength is big, and is sturdy and durable, but it is very inconvenient to get on and off.The oblique beam structure vehicle frame is cant beam of welding between lower inclined beam and back seat standpipe, gets on and off to make things convenient for the cyclist, but because the stress point of cant beam moves down, and making vehicle frame is not that triangle is stressed, and therefore, holding capacity intensity is little, easily produces the waist phenomenon of collapsing.
The purpose of this utility model is to provide a kind of get on and off convenient and big, the robust manual tricycle double bent tube of bearing strength vehicle frame.
The utility model has a car body pedestal that is made of underframe and back vent behind threeway vertical tube, lower inclined beam, five-way sleeve pipe, back seat standpipe, the car, is welded with the camber beam of a front and back symmetry between threeway riser upper portions and back vent respectively.
Above-mentioned manual tricycle double bent tube vehicle frame being welded with arched girder respectively between the underframe behind lower inclined beam and back seat standpipe and back seat standpipe and the car, plays the aiding support effect, so that vehicle frame is firmer.
Above-mentioned manual tricycle double bent tube vehicle frame is welded with the support lacing wire between camber beam and lower inclined beam.
Above-mentioned manual tricycle double bent tube vehicle frame is welded with reinforced rib between two camber beams.
This double bent tube vehicle frame bearing strength is big, sturdy and durable, the difficult generation waist phenomenon of collapsing, and get on and off conveniently, operate more laborsaving.
The drawing explanation:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is a birds-eye view of the present utility model.
Provide embodiment below in conjunction with accompanying drawing:
This manual tricycle double bent tube vehicle frame has one by threeway vertical tube 1, lower inclined beam 2, five-way sleeve pipe 3, back seat standpipe 7, the car body pedestal that underframe 5 and back vent 6 constitute behind the car, be welded with a camber beam 9 that front and back are symmetrical on the upper side between the position respectively on threeway vertical tube 1 top and back vent 6 middle parts, and be welded with reinforced rib 8 between two camber beams 9, between two camber beams 9, be welded with connecting plate, between this connecting plate and lower inclined beam 2, be welded with and support lacing wire 10, the gap location of said back seat standpipe between two reinforced ribs 8 passes, being welded with arched girder 4 respectively between the underframe 5 between lower inclined beam 2 and the back seat standpipe 7 and behind back seat standpipe 7 and the car, play the aiding support effect.
