Abstract
The invention relates to a bicycle frame, in particular to a bicycle frame stable in structure and small in a bicycle body. The bicycle frame comprises a front-fork socket, a saddle casing, a middle-axle casing and a rear-axle fork frame, the front-fork socket and the saddle casing are connected through a top bar, the middle-axle casing and the front-fork socket are connected through a bottom bar, the saddle casing and the middle-axle casing are connected through a vertical beam, and one end of the rear-axle fork frame is used for mounting of a rear axle while the other end is fixedly connected with the middle-axle casing. Strength of the bicycle body is effectively improved through a tri-prism tubular structure, a triangular prism close to top bar and bottom bar sides is of a tri-prism edge surface of the vertical beam, a triangular prism close to the rear-axle fork frame is a tri-prism edge of the vertical beam, a circular-arc concave surface is arranged on the middle lower side of the vertical beam, a wheel protrudes into the circular-arc concave surface, the length of the bicycle body is effectively shortened, and the bicycle body is lighter.
Description
Technical field
The present invention relates to a kind of cycle frame, particularly relate to the bicycle rack that a kind of stabilized structure car body is short and small.
Background technology
In prior art, the vehicle frame of bicycle generally comprises the front fork sleeve for installing front fork, for installing the saddle sleeve pipe of saddle, for installing the axis sleeve pipe of axis, connected by upper beam between front fork sleeve and saddle sleeve pipe, being connected by underbeam between axis sleeve pipe and front fork sleeve, and be connected by vertical beam between saddle sleeve pipe with axis sleeve pipe, also establishing the rear axle crotch for installing trailing wheel in addition, rear axle crotch one end is for installing rear axle, and the other end is fixedly connected with axis sleeve pipe.
But ordinary bicycle car body is longer in prior art, and all car body beams are cylindric, and car body is hit power difference, and structure built on the sand.
Summary of the invention
Technical matters to be solved by this invention overcomes the deficiencies in the prior art, provides the bicycle rack that a kind of stabilized structure car body is short and small.
The present invention is achieved by the following technical programs:
The bicycle rack that a kind of stabilized structure car body is short and small, comprise front fork sleeve, saddle sleeve pipe, axis sleeve pipe and rear axle crotch, connected by upper beam between front fork sleeve and saddle sleeve pipe, connected by underbeam between axis sleeve pipe and front fork sleeve, and be connected by vertical beam between saddle sleeve pipe with axis sleeve pipe, rear axle crotch one end is for installing rear axle, the other end is fixedly connected with axis sleeve pipe, upper beam, underbeam and vertical beam are triangular prism tubular structure, triangular prism wherein near upper beam and underbeam side is the triangular prism faceted pebble of vertical beam, triangular prism near rear axle crotch is the triangular prism corner angle of vertical beam, the middle downside of described vertical beam is provided with circular arc concave surface.
The invention has the beneficial effects as follows:
Due to upper beam, underbeam and vertical beam are triangular prism tubular structure, triangular prism wherein near upper beam and underbeam side is the triangular prism faceted pebble of vertical beam, triangular prism near rear axle crotch is the triangular prism corner angle of vertical beam, the middle downside of described vertical beam is provided with circular arc concave surface, triangular prism tubular structure actv. improves car body strength, triangular prism wherein near upper beam and underbeam side is the triangular prism faceted pebble of vertical beam, triangular prism near rear axle crotch is the triangular prism corner angle of vertical beam, the middle downside of described vertical beam is provided with circular arc concave surface, wheel convex enter vertical beam circular arc concave surface, effective shortening length over ends of body, make car body more light.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
In figure: 1. saddle sleeve pipe, 2. upper beam, 3. front fork sleeve, 4. underbeam, 5. axis sleeve pipe, 6. rear axle crotch, 7. circular arc concave surface, 8. vertical beam.
Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing and most preferred embodiment, the present invention is described in further detail.
As shown in the figure, the present invention includes front fork sleeve 3, saddle sleeve pipe 1, axis sleeve pipe 5 and rear axle crotch 6, connected by upper beam 2 between front fork sleeve and saddle sleeve pipe, connected by underbeam 4 between axis sleeve pipe and front fork sleeve, and be connected by vertical beam 8 between saddle sleeve pipe with axis sleeve pipe, rear axle crotch one end is for installing rear axle, the other end is fixedly connected with axis sleeve pipe, upper beam, underbeam and vertical beam are triangular prism tubular structure, triangular prism wherein near upper beam and underbeam side is the triangular prism faceted pebble of vertical beam, triangular prism near rear axle crotch is the triangular prism corner angle of vertical beam, the middle downside of described vertical beam is provided with circular arc concave surface 7.
Due to upper beam, underbeam and vertical beam are triangular prism tubular structure, triangular prism wherein near upper beam and underbeam side is the triangular prism faceted pebble of vertical beam, triangular prism near rear axle crotch is the triangular prism corner angle of vertical beam, the middle downside of described vertical beam is provided with circular arc concave surface, triangular prism tubular structure actv. improves car body strength, triangular prism wherein near upper beam and underbeam side is the triangular prism faceted pebble of vertical beam, triangular prism near rear axle crotch is the triangular prism corner angle of vertical beam, the middle downside of described vertical beam is provided with circular arc concave surface, wheel convex enter vertical beam circular arc concave surface, effective shortening length over ends of body, make car body more light.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
