Abstract
The utility model relates to a rotary folded bicycle frame, which comprises a frame body and is characterized in that the frame body comprises a front frame body and a rear frame body, wherein the front part of the rear frame body is connected in a rotational way in the middle by an axis and a spindle perpendicular to a plane, the rear part of the front frame body is connected to a saddle tube sleeve for insertion of a saddle tube, a plug bush for the insertion of the saddle tube is disposed at a position on the rear frame body, which is below the saddle tube sleeve and corresponding to the saddle tube sleeve, and the plug bush or the saddle tube sleeve are equipped with a quick release for locking of the saddle tube. Advantages are that the rotary folded bicycle frame is simple in structure, novel in appearance and good in stability of the bicycle frame.
Description
Technical field
The utility model belongs to technical field of bicycles, particularly relates to a kind of rotary folding bicycle vehicle frame.
Background technology
Along with the theory of " green traffic, low-carbon (LC) trip " is constantly approved by people, bicycle has become the main traffic instrument of people's trip.Folding bicycle is a kind of of bicycle, the vehicle frame of folding bicycle and handlebar etc. can fold, thereby the volume of bicycle is reduced greatly, be conducive to depositing and carrying of bicycle, traditional folding bicycle frame comprises support body, and support body is provided with folding locking device, folding locking device is generally the folding buckle of hinge shape, the structure of this vehicle frame is single, and configuration design is inflexible, and the resistance to overturning of vehicle frame is poor.
Summary of the invention
The utility model is single for solving the body frame structure for automotive existing in known technology, and profile is inflexible, and poor stability obtain technical matters and provide a kind of simple in structure, profile is novel, the rotary folding bicycle vehicle frame of vehicle frame good stability.
The utility model for the technical scheme that solves the technical matters that exists in known technology and take is: 1. a rotary folding bicycle vehicle frame, comprise support body, it is characterized in that: described support body comprises front frame body and back frame body, the front portion of described back frame body is rotationally connected by the axis rotating shaft vertical with horizontal surface with the middle part of described front frame body, the rear portion of described front vehicle frame is connected with the saddle pipe sleeve pipe for plug-in mounting saddle pipe, on described back frame body, be positioned at the below and the corresponding sleeve being provided with for plug-in mounting saddle pipe of described saddle pipe sleeve pipe of described saddle pipe sleeve pipe, on described sleeve or saddle pipe sleeve pipe, be provided with for locking the quick detach of saddle pipe.
The utility model can also adopt following technical scheme:
The front portion of described back frame body is connected with lower swivel base, and the middle part of described front frame body connects upper swivel base, and described lower swivel base is body, has plug-in mounting and enter described lower swivel base and the axis rotating shaft vertical with horizontal surface on described upper swivel base.
Described lower swivel base is welded on described back frame body, and described upper swivel base is welded on described front frame body.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, design a kind of folding stand of new structure, support body in the utility model is comprised of two parts, two parts are front frame body and back frame body, front frame body is connected by rotating shaft with back frame body, front frame body and back frame body relatively rotate to realize folding, and this structure is not only simple, novel, and the good stability of vehicle frame.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, front frame body; 2, back frame body; 3, axle turns; 4, saddle pipe; 5, saddle pipe sleeve pipe; 6, sleeve; 7, lower swivel base; 8, upper swivel base.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of rotary folding bicycle vehicle frame, comprises support body, and support body comprises front frame body 1 and back frame body 2.The front portion of back frame body 2 turns 3 with the middle part of front frame body 1 by the axis rotating shaft vertical with horizontal surface and is dynamically connected, and front frame body 13 rotates around the shaft, can realize the folding of support body.The rear portion of front vehicle frame 1 is connected with the saddle pipe sleeve pipe 5 for the saddle pipe 4 of plug-in mounting bicycle, the below sleeve 6 that be provided with for plug-in mounting saddle pipe 4 corresponding to saddle pipe sleeve pipe 5 that is positioned at saddle pipe sleeve pipe 5 on back frame body 2, is provided with for locking the quick detach of saddle pipe 4 on sleeve 6 or saddle pipe sleeve pipe 5.Saddle pipe 4 inserts saddle pipe sleeve pipe 5 and inserts sleeve 6, and with quick-detachment locking, the position of front frame body 1 and back frame body 2 cannot be rotated by saddle pipe 4 restrictions, and the position between front frame body 1 and back frame body 2 is fixed, and it is stable that vehicle frame is stablized integral structure; Loosening quick detach, extracts saddle pipe 4 out sleeve 6, between front frame body 1 and back frame body 2, without fixed sturcture, between front frame body 1 and back frame body 2, can sway, and with this, realizes rotary folding.After this vehicle frame in novel fixes, between front frame body and back frame body, can not produce lateral deviation, there will not be front frame body to left avertence, back frame body is just to the situation of right avertence.
In the present embodiment, the front portion of back frame body 2 is connected with lower swivel base 7, and the middle part of front frame body 1 connects upper transposon 18, and lower swivel base 7 is body, has plug-in mounting and enter lower swivel base 7 and the axis rotating shaft 3 vertical with horizontal surface on upper transposon 18.The supporting installation by upper transposon 18 and lower swivel base 7 of front frame body 1 and back frame body 2 realizes and being rotationally connected.Lower swivel base 7 is welded on back frame body 2, and upper transposon 18 is welded on front frame body 1.
Above-mentioned embodiment is only to functional descriptions of the present utility model; not design of the present utility model and scope are limited; do not departing under the prerequisite of the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model: above-mentioned sleeve is replaced with to the trepanning of being located on back frame body, within all dropping on protection domain of the present utility model.
