Abstract
The utility model relates to a bicycle frame, in particular to a shock-absorption bicycle frame with a half-moon-shaped rear shaft fork frame. The shock-absorption bicycle comprises a front fork sleeve, a saddle sleeve, a middle shaft sleeve and the rear shaft fork frame, wherein the middle shaft sleeve and the front fork sleeve are connected by virtue of an oblique beam; the saddle sleeve and the middle of the oblique beam are connected by virtue of a support beam; the front fork sleeve and the middle of the support beam are connected by virtue of a connecting beam; the rear shaft fork frame is of a half-moon-shaped structure; the front end of the rear shaft fork frame is hinged with the oblique beam by virtue of a rotating shaft; and the middle of the rear shaft fork frame is connected with the support beam by virtue of a shock-absorption spring. Due to the structure, the compression strength can be increased, so that the structure is more stable; and the rear shaft fork frame is of the half-moon-shaped structure, the front end of the rear shaft fork frame is hinged with the oblique beam by virtue of the rotating shaft, the middle of the rear shaft fork frame and the support beam are connected by virtue of the shock-absorption spring, so that the shock is absorbed by virtue of the deformation of the bicycle frame as much as possible, and the safety and the comfort of a bicycle are improved.
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 half moon rear axle crotch.
Background technology
The vehicle frame of bicycle generally comprises for the front fork sleeve that front fork is installed in the prior art, be used for installing the saddle sleeve pipe of saddle, be used for installing the axis sleeve pipe of axis, connect by putting the beams in place between front fork sleeve and the saddle sleeve pipe, connect by cant beam between axis sleeve pipe and the front fork sleeve, and be connected by vertical beam between saddle sleeve pipe and the axis sleeve pipe, also establish in addition the rear axle crotch for the installation trailing wheel, rear axle crotch one end is used for rear axle is installed, and the other end is captiveed joint with the axis sleeve pipe.
But in the prior art since the rear axle crotch captive joint with the axis sleeve pipe so that bicycle rack on the whole can't deformation and the absorption driving process in jolting, when pavement conditions is bad, cause easily the too early fatigue of user, affect safety traffic and comfort level.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and the shock-absorptive frame of bicycle of the half moon rear axle crotch that a kind of stabilized structure has fine damping effect is provided.
The utility model is to be achieved by the following technical programs:
A kind of shock-absorptive frame of bicycle of half moon rear axle crotch, comprise front fork sleeve, saddle sleeve pipe, axis sleeve pipe and rear axle crotch, be connected by cant beam between axis sleeve pipe and the front fork sleeve, saddle sleeve pipe and cant beam are connected by support beam between the middle part, front fork sleeve and support beam are connected by tie-beam between the middle part, described rear axle crotch is the half moon structure, and rear axle crotch front end is hinged by rotating shaft and cant beam, is connected by shock-proof spring in the middle part of the described rear axle crotch with between the support beam.
The beneficial effects of the utility model are:
Owing to be connected by cant beam between axis sleeve pipe and the front fork sleeve, saddle sleeve pipe and cant beam are connected by support beam between the middle part, front fork sleeve and support beam are connected by tie-beam between the middle part, can increase its compressive strength makes structure more firm, described rear axle crotch is the half moon structure in addition, rear axle crotch front end is hinged by rotating shaft and cant beam, be connected by shock-proof spring in the middle part of the described rear axle crotch with between the support beam, deformation by bicycle rack comes absorbing vibration as much as possible, improves safety and the traveling comfort of bicycle.
Description of drawings
Fig. 1 is main TV structure scheme drawing of the present utility model.
Among the figure: 1. saddle sleeve pipe, 2. support beam, 3. front fork sleeve, 4. cant beam, 5. axis sleeve pipe, 6. rear axle crotch, 7. shock-proof spring, 8. tie-beam.
The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with accompanying drawing and most preferred embodiment.
As shown in Figure 1, the utility model comprises front fork sleeve 3, saddle sleeve pipe 1, axis sleeve pipe 5 and rear axle crotch 6, be connected by cant beam 4 between axis sleeve pipe and the front fork sleeve, saddle sleeve pipe and cant beam are connected by support beam 2 between the middle part, front fork sleeve and support beam are connected by tie-beam 8 between the middle part, described rear axle crotch is the half moon structure, and rear axle crotch front end is hinged by rotating shaft and cant beam, is connected by shock-proof spring 7 in the middle part of the described rear axle crotch with between the support beam.
Owing to be connected by cant beam between axis sleeve pipe and the front fork sleeve, saddle sleeve pipe and cant beam are connected by support beam between the middle part, front fork sleeve and support beam are connected by tie-beam between the middle part, can increase its compressive strength makes structure more firm, described rear axle crotch is the half moon structure in addition, rear axle crotch front end is hinged by rotating shaft and cant beam, be connected by shock-proof spring in the middle part of the described rear axle crotch with between the support beam, deformation by bicycle rack comes absorbing vibration as much as possible, improves safety and the traveling comfort of bicycle.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from 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.
