Abstract
The utility model relates to a bicycle frame, in particular to a damping bicycle frame with the stable structure. A vertical beam is arranged at the lower end of a saddle casing pipe, the lower end of the vertical beam and the lower end of an inclined beam are provided with a right-angle reinforcing fixing beam, an upper beam is arranged between the reinforcing fixing beam and a front fork casing pipe, the portion, at the right-angle bent position, of the reinforcing fixing beam is provided with a connecting plate, a rear axle fork frame is in a half-moon arc shape, the end of the rear axle fork frame is connected with the lower middle side of the inclined beam through a hinge shaft, the rear axle fork frame penetrates through the reinforcing fixing beam from two sides, and a damping spring is connected between the half-moon arc bent position and the connecting plate. The position where the rear axle fork frame is in the half-moon arc shape is hinged to the inclined frame is used as a fulcrum, shock is absorbed through the action of the damping spring and the deformation of the bicycle frame as far as possible, safety and comfort of the bicycle are improved, the right-angle reinforcing fixing beam is arranged in the middle of the whole bicycle body and used as the center for bicycle body connection, and the stability of the whole bicycle body structure is strengthened.
Description
Technical field
The utility model relates to a kind of cycle frame, relates in particular to a kind of shock-absorptive frame of bicycle 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 cant beam, 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, because rear axle crotch is fixedly connected with axis sleeve pipe, make the bicycle rack on the whole cannot deformation and absorb jolting in driving process, when pavement conditions is bad, easily cause the fatigue that user is too early, affect safety traffic and comfort level.
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 shock-absorptive frame of bicycle of stabilized structure is provided.
The utility model is to be achieved by the following technical programs:
A kind of shock-absorptive frame of bicycle of stabilized structure, comprise front fork sleeve, saddle sleeve pipe, axis sleeve pipe and rear axle crotch, between described front fork sleeve and axis sleeve pipe, be provided with cant beam, it is characterized in that, described saddle sleeve pipe lower end is provided with vertical beam, described vertical beam lower end and cant beam lower end are provided with square and strengthen fixed beam, between described reinforcement fixed beam and front fork sleeve pipe, be provided with upper beam, described reinforcement fixed beam is provided with connecting panel in right-angle folding crook, described rear axle crotch is first quarter moon arc, in rear axle crotch end and cant beam, downside passes through stud connection, rear axle crotch passes from both sides strengthens fixed beam, and be connected with damping spring between first quarter moon arc fold bending place and connecting panel.
The beneficial effects of the utility model are:
Because described saddle sleeve pipe lower end is provided with vertical beam, described vertical beam lower end and cant beam lower end are provided with square and strengthen fixed beam, between described reinforcement fixed beam and front fork sleeve pipe, be provided with upper beam, described reinforcement fixed beam is provided with connecting panel in right-angle folding crook, described rear axle crotch is first quarter moon arc, in rear axle crotch end and cant beam, downside is by stud connection, and rear axle crotch passes and strengthens fixed beam from both sides, and is connected with damping spring between first quarter moon arc fold bending place and connecting panel.The first quarter moon arc rear axle of take crotch with hinged place cant beam be fulcrum, by the effect of damping spring, and the deformation by bicycle rack carrys out absorbing vibration as much as possible, improve safety and the traveling comfort of bicycle, square is strengthened fixed beam and is located at whole car body middle part, take it as the car body that core connects, and has strengthened the steadiness of whole body construction.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure: 1. saddle sleeve pipe, 2. strengthen fixed beam, 3. upper beam, 4. front fork sleeve pipe, 5. cant beam, 6. hinge, 7. axis sleeve pipe, 8. damping spring, 9. rear axle crotch, 10. 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, saddle sleeve pipe 1, axis sleeve pipe 7 and rear axle crotch 9, between described front fork sleeve and axis sleeve pipe, be provided with cant beam 5, described saddle sleeve pipe lower end is provided with vertical beam 10, described vertical beam lower end and cant beam lower end are provided with square and strengthen fixed beam 2, between described reinforcement fixed beam and front fork sleeve pipe 4, be provided with upper beam 3, described reinforcement fixed beam is provided with connecting panel in right-angle folding crook, described rear axle crotch is first quarter moon arc, rear axle crotch end is connected by hinge 6 with downside in cant beam, rear axle crotch passes from both sides strengthens fixed beam, and between first quarter moon arc fold bending place and connecting panel, be connected with damping spring 8.
Because described saddle sleeve pipe lower end is provided with vertical beam, described vertical beam lower end and cant beam lower end are provided with square and strengthen fixed beam, between described reinforcement fixed beam and front fork sleeve pipe, be provided with upper beam, described reinforcement fixed beam is provided with connecting panel in right-angle folding crook, described rear axle crotch is first quarter moon arc, in rear axle crotch end and cant beam, downside is by stud connection, and rear axle crotch passes and strengthens fixed beam from both sides, and is connected with damping spring between first quarter moon arc fold bending place and connecting panel.The first quarter moon arc rear axle of take crotch with hinged place cant beam be fulcrum, by the effect of damping spring, and the deformation by bicycle rack carrys out absorbing vibration as much as possible, improve safety and the traveling comfort of bicycle, square is strengthened fixed beam and is located at whole car body middle part, take it as the car body that core connects, and has strengthened the steadiness of whole body construction.
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.
