Abstract
The utility model relates to a rotatable folding frame which can effectively reduce the occupied size of a car body, and be convenient to place and carry. The rotatable folding frame comprises a rear frame body, a front frame body and a seat tube, wherein a first rotating shaft is arranged on the front side of the rear frame body, a second rotating shaft is arranged on the lower side of the front frame body, the first rotating shaft and the second rotating shaft are coaxial and can relatively rotate, a first middle tube is arranged in the middle of the rear frame body, a second middle tube is arranged on the rear side of the front frame body, the seat tube can be inserted into the first middle tube and the second middle tube, the outer side of the first middle tube and the outer side of the second middle tube are respectively provided with a seat tube locking device, when the two seat tube locking devices are locked, the front frame body and the rear frame body are connected into the whole frame, when the seat tube locking devices are loosened, the seat tube can be pulled out from the two middle tubes, at the moment, the front frame body and the rear frame body enable the frame to be rotatably folded under the rotation of the first rotating shaft and the second rotating shaft, and therefore the aims of reducing the occupied size of the car body, facilitating placement and facilitating carry are achieved.
Description
Technical field
The utility model relates to a kind of bicycle, relates in particular to a kind of rotatable folding vehicle frame.
Background technology
Bicycle has become the indispensable vehicle in people's daily life, generally speaking, bicycle comprises vehicle frame, wheel, foot-operated, handlebar and vehicle seat, wherein vehicle frame is the skeleton of whole bicycle, be the basic structure that consists of bicycle, other parts all are directly or indirectly to be installed on the vehicle frame.So the structure of vehicle frame and performance are the key factors that determines the bicycle quality.Existing bicycle although can realize folding, is doubling mostly, between crossbeam and rear supporting tube rotating shaft is set.Same, what present vehicle frame generally adopted is common carbon steel copper pipe, process is welded, is combined again, but the vehicle frame quality that this material is made weighs, and volume is large, is not easy to transportation, stores.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of car body that can effectively reduce and takies volume, the rotatable folding vehicle frame of conveniently placing and carrying.
Rotatable folding vehicle frame of the present utility model, comprise rear vehicle frame, front vehicle frame and seat pipe, the front side of described rear vehicle frame is provided with the first rotating shaft, the downside of described front vehicle frame is provided with the second rotating shaft, the first rotating shaft and the second rotating shaft are coaxial and can relatively rotate, the middle part of described rear vehicle frame is provided with pipe in first, the rear side of front vehicle frame is provided with pipe in second, described seat pipe can insert in described first in the pipe and second in the pipe, in described first in the pipe and second outside of pipe be respectively equipped with a pipe locking device, when the locking bed pipe locking device, front vehicle frame and rear vehicle frame are connected as a whole vehicle frame, when unclamping pipe locking device, extract in the pipe among two of the seat Guan Kecong, this moment front vehicle frame and rear vehicle frame under the rotation of the first rotating shaft and the second rotating shaft with the vehicle frame rotary folding.
Further, the inside of described the first rotating shaft and the second rotating shaft is provided with bearing pin.
By such scheme, rotatable folding vehicle frame of the present utility model has the following advantages at least: the utility model is when two seat pipe locking devices of locking, front/rear frame is connected as a whole vehicle frame, when unclamping pipe locking device, the seat pipe can be pulled out middle pipe, the time front vehicle frame and rear vehicle frame under the rotation of the first rotating shaft and the second rotating shaft with the vehicle frame rotary folding, reduce car body and take volume, the purpose of conveniently placing and carrying so reach.
Description of drawings
Fig. 1 is the structural representation of the utility model rotatable folding vehicle frame;
Fig. 2 is vehicle frame rotary folding view.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Referring to illustrated in figures 1 and 2, a kind of rotatable folding vehicle frame, comprise rear vehicle frame 1, front vehicle frame 4 and seat pipe 2, the front side of rear vehicle frame 1 is provided with the first rotating shaft 11, the downside of front vehicle frame 4 is provided with the second rotating shaft 41, the first rotating shaft 11 and the second rotating shaft 41 are coaxial and can relatively rotate, the inside of the first rotating shaft 11 and the second rotating shaft 41 is provided with bearing pin 5, the middle part of rear vehicle frame 1 is provided with manages 12 in first, the rear side of front vehicle frame 4 is provided with manages 42 in second, seat pipe 2 can insert in described first in the pipe 12 and second in the pipe 42, in first in the pipe 12 and second outside of pipe 42 be respectively equipped with a pipe locking device 3, when locking bed pipe locking device 3, front vehicle frame 4 and rear vehicle frame 1 are connected as a whole vehicle frame, when unclamping a pipe locking device 3, seat pipe 2 is extracted in the pipe from two, simultaneously, front vehicle frame 4 and rear vehicle frame 1 rotate around the first rotating shaft 11 and the second rotating shaft 41 respectively, with the vehicle frame rotary folding, so just reach and reduce car body and take volume, conveniently place and carry and to get purpose.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
