Abstract
The utility model relates to a bicycle frame and particularly relates to a stable-structure bicycle frame. An inclined tube is arranged between a top tube and a down tube, the top tube parallel to the down tube is arranged between the inclined tube and a front fork sleeve, a reinforcing bar is arranged between the top tube and the down tube, the inclined tube and the down tube are square-column tubes, and ridge ribs are arranged on the square-column tubes. According to the bicycle frame, a top tube between a front fork sleeve and a saddle sleeve is replaced by the inclined tube and the top tube parallel to the down tube, so that the impact force can be dispersed by the inclined tube and the top tube; the reinforcing bar is arranged between the top tube and the down tube, so that the bicycle body strength is effectively improved; the inclined tube and the down tube are square-column tubes, and ridge ribs are arranged on the square-column tubes, accordingly, the bearing bicycle body tube strength is improved.
Description
Technical field
The utility model relates to a kind of cycle frame, relates in particular to a kind of bicycle rack of stabilized structure.
Background technology
In prior art, the vehicle frame of bicycle generally comprises for the front fork sleeve of front fork is installed, for the saddle sleeve pipe of saddle is installed, for the axis sleeve pipe of axis is installed, between front fork sleeve and saddle sleeve pipe, by upper beam, connect, between axis sleeve pipe and front fork sleeve, by underbeam, connect, and by vertical beam, be connected between saddle sleeve pipe and axis sleeve pipe, also establish in addition for the rear axle crotch of trailing wheel is installed, rear axle crotch one end is used for installing rear axle, and the other end is fixedly connected with axis sleeve pipe.
But in prior art between ordinary bicycle upper beam and underbeam without annexation, lack whole structure, and all car body beams are cylindric, the car body power that is hit is poor, structure is built on the sand.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of bicycle rack of stabilized structure is provided.
The utility model is to be achieved by the following technical programs:
A kind of bicycle rack of stabilized structure, comprise front fork sleeve, saddle sleeve pipe, axis sleeve pipe and rear axle crotch, between described saddle sleeve pipe and axis sleeve pipe, be provided with vertical beam, between described front fork sleeve and axis sleeve pipe, be provided with underbeam, between described vertical beam and underbeam, be provided with cant beam, between described cant beam and front fork sleeve pipe, be provided with the upper beam parallel with underbeam, between described upper beam and underbeam, be provided with reinforced rib, described cant beam and underbeam are flat column beam, and described flat column beam is provided with stupefied shape rib.
The beneficial effects of the utility model are:
Owing to being provided with cant beam between described vertical beam and underbeam, between described cant beam and front fork sleeve pipe, be provided with the upper beam parallel with underbeam, between described upper beam and underbeam, be provided with reinforced rib, described cant beam and underbeam are flat column beam, described flat column beam is provided with stupefied shape rib, by cant beam and the upper beam parallel with underbeam, replace being originally located at the upper beam between front fork sleeve and saddle sleeve pipe, impulsive force can be disperseed by cant beam and upper beam of the present utility model, and be provided with reinforced rib between described upper beam and underbeam, actv. improves car body strength, cant beam and underbeam are flat column beam, flat column beam is provided with stupefied shape rib, the intensity of the car body beam of load-bearing is improved.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure: 1. saddle sleeve pipe, 2. upper beam, 3. front fork sleeve, 4. stupefied shape rib, 5. reinforced rib, 6. underbeam, 7. axis sleeve pipe, 8. rear axle crotch, 9. vertical beam.
The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in the figure, the utility model comprises front fork sleeve 3, saddle sleeve pipe 1, axis sleeve pipe 7 and rear axle crotch 8, between described saddle sleeve pipe and axis sleeve pipe, be provided with vertical beam 9, between described front fork sleeve and axis sleeve pipe, be provided with underbeam 6, between described vertical beam and underbeam, be provided with cant beam, between described cant beam and front fork sleeve pipe, be provided with the upper beam parallel with underbeam 2, between described upper beam and underbeam, be provided with reinforced rib 5, described cant beam and underbeam are flat column beam, and described flat column beam is provided with stupefied shape rib 4.
Owing to being provided with cant beam between described vertical beam and underbeam, between described cant beam and front fork sleeve pipe, be provided with the upper beam parallel with underbeam, between described upper beam and underbeam, be provided with reinforced rib, described cant beam and underbeam are flat column beam, described flat column beam is provided with stupefied shape rib, by cant beam and the upper beam parallel with underbeam, replace being originally located at the upper beam between front fork sleeve and saddle sleeve pipe, impulsive force can be disperseed by cant beam and upper beam of the present utility model, and be provided with reinforced rib between described upper beam and underbeam, actv. improves car body strength, cant beam and underbeam are flat column beam, flat column beam is provided with stupefied shape rib, the intensity of the car body beam of load-bearing is improved.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of 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.
