Description
Technical field
The utility model relates to a kind of cycle frame more particularly to a kind of structurally stable cycle frames.
Background technique
Main structure of the cycle frame as bicycle, connects all parts of bicycle, sends out in whole bicycle
Wave extremely important effect.The vehicle frame overwhelming majority of bicycle is all that tubular structure bracket passes through triangle frame in the prior art
Structure principle is welded, and in the prior art since rear axle crotch upper and lower ends are welded on vertical beam side, stress is concentrated, and is easy
It causes rear tailstock structure built on the sand and lacks overall effect.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and it is steady to provide a kind of structure
Solid cycle frame.
The utility model is to be achieved by the following technical programs:
A kind of structurally stable cycle frame, including front fork sleeve, saddle casing, axis casing and rear axle crotch,
It is characterized in that, vertical beam is equipped between the saddle casing and axis casing, upper beam, institute are equipped between the front fork sleeve and vertical beam
It is affixed with vertical beam to state upper beam rear end, cant beam, the bending of rear axle crotch rear end are equipped between the axis casing and front fork sleeve
Place is equipped with rear axle pintle, and rear axle crotch upper end extends to form extended segment beam, the extended segment beam from vertical beam two sides to upper beam
Front end is smoothly affixed with upper beam, and rear axle crotch lower end and axis casing are affixed, sets between the beam of rear axle crotch extended segment
There is rear axle crotch strut, the rear axle crotch strut both ends and rear axle crotch are affixed, the rear axle crotch strut middle part and vertical beam
It is affixed.
The beneficial effects of the utility model are:
Since rear axle crotch upper end extends to form extended segment beam, the extended segment tail beam from vertical beam two sides to upper beam
It being smoothly connected with upper beam, rear axle crotch lower end and axis casing are affixed, rear axle crotch strut is equipped between the rear axle crotch,
The rear axle crotch strut both ends and rear axle crotch are affixed, affixed with vertical beam in the middle part of the rear axle crotch strut, so that rear yoke
Frame is in isosceles triangle, avoids stress and concentrates in vertical beam, extended segment beam front end with upper beam is affixed connect entire car body more
Step up close, globality effect is strong, more firm.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model,
Fig. 2 is the side structure schematic view of the utility model.
In figure: 1. saddle casings, 2. vertical beams, 3. upper beams, 4. front fork sleeves, 5. cant beams, 6. axis casings, yoke after 7.
Frame, 8. rear axle pintles, 9. extended segment beams, 10. rear axle crotch struts.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
As shown, the utility model includes front fork sleeve 4, saddle casing 1, axis casing 6 and rear axle crotch 7, it is described
It is equipped with vertical beam 2 between saddle casing 1 and axis casing 6, upper beam 3, the upper beam 3 are equipped between the front fork sleeve 4 and vertical beam 2
Rear end and vertical beam 2 are affixed, and cant beam 5, the 7 rear end bending place of rear axle crotch are equipped between the axis casing 6 and front fork sleeve 4
Equipped with rear axle pintle 8,7 upper end of rear axle crotch extends to form extended segment beam 9, the extended segment from 2 two sides of vertical beam to upper beam 3
9 front end of beam is smooth affixed with upper beam 3, and 7 lower end of rear axle crotch and axis casing 6 are affixed, rear axle crotch extended segment beam 9
Between be equipped with rear axle crotch strut 10,10 both ends of rear axle crotch strut and rear axle crotch 7 are affixed, the rear axle crotch strut
10 middle parts are affixed with vertical beam 2.
Above-mentioned " being equipped with " indicates to be fixedly connected, and the form being fixedly connected can be welding.
Since rear axle crotch upper end extends to form extended segment beam, the extended segment tail beam from vertical beam two sides to upper beam
It being smoothly connected with upper beam, rear axle crotch lower end and axis casing are affixed, rear axle crotch strut is equipped between the rear axle crotch,
The rear axle crotch strut both ends and rear axle crotch are affixed, affixed with vertical beam in the middle part of the rear axle crotch strut, so that rear yoke
Frame is in isosceles triangle, avoids stress and concentrates in vertical beam, extended segment beam front end with upper beam is affixed connect entire car body more
Step up close, globality effect is strong, more firm.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
