Abstract

The utility model relates to a bicycle frame with a shock absorption function. The bicycle frame comprises a front fork sleeve, a saddle sleeve, a middle shaft sleeve and a rear shaft fork frame. A vertical beam is arranged on the lower portion of the saddle sleeve, one side of the front fork sleeve is provided with double inclined beams which are connected end to end and encircled with each other, a reinforcing plate is fixedly connected to the upper portion of the bent position of the upper beam in the double inclined beams, a connecting beam is fixedly connected between the reinforcing plate and the vertical beam, the middle shaft sleeve is arranged at the lower end of the rear shaft fork frame, the lower end of the rear shaft fork frame is hinged to the tail end of the lower beam in the double inclined beams through a hinge shaft, and a shock absorption spring is arranged between the upper end of the rear shaft fork frame and the reinforcing plate in a connected mode. Due to the fact that one side of the front fork sleeve is provided with the double inclined beams which are connected end to end and encircled with each other and the reinforcing plate arranged on the upper portion of the bent position of the upper beam in the double inclined beams, the strength of a bicycle body is effectively enhanced; and due to the facts that the lower end of the rear shaft fork frame is hinged to the tail end of the lower beam in the double inclined beams through the hinge shaft and the shock absorption spring is arranged between the upper end of the rear shaft fork frame and the reinforcing plate in the connected mode, shock is absorbed through deformation of the bicycle frame as far as possible, and the safety and the comfort of a bicycle are improved.

Description

A kind of cycle frame with shock-absorbing function

Technical field

The utility model relates to a kind of cycle frame, relates in particular to a kind of cycle frame with shock-absorbing function.

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 cycle frame with shock-absorbing function is provided.

The utility model is to be achieved by the following technical programs:

A kind of cycle frame with shock-absorbing function, comprise front fork sleeve, saddle sleeve pipe, axis sleeve pipe and rear axle crotch, described saddle sleeve pipe has vertical beam, described front fork sleeve one side is provided with head and the tail and connects the double oblique beams of encircling mutually, the bending part top of the upper beam in described double oblique beams is connected with reinforced plate, between described reinforced plate and vertical beam, be connected with tie-beam, described axis sleeve pipe is located at rear axle crotch lower end, underbeam end in described rear axle crotch lower end and double oblique beams is hinged by hinge, between described rear axle crotch upper end and reinforced plate, is connected with damping spring.

Between described double oblique beams, front portion is provided with strip rib.

The beneficial effects of the utility model are:

Because being provided with head and the tail, described front fork sleeve one side connects the double oblique beams of encircling mutually and the reinforced plate of being located at the bending part top of the upper beam in double oblique beams, actv. has increased the intensity of car body, underbeam end in rear axle crotch lower end and double oblique beams is hinged by hinge, between rear axle crotch upper end and reinforced plate, be connected with damping spring, deformation by bicycle rack carrys out absorbing vibration as much as possible, improves safety and the traveling comfort of bicycle.

Accompanying drawing explanation

Fig. 1 is main TV structure schematic diagram of the present utility model.

In figure: 1. rear axle crotch, 2. vertical beam, 3. saddle sleeve pipe, 4. tie-beam, 5. reinforced plate, the 6. upper beam in double oblique beams, 7. front fork sleeve, 8. strip rib, the 9. underbeam in double oblique beams, 10. hinge, 11. axis sleeve pipes.

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 7, saddle sleeve pipe 3, axis sleeve pipe 11 and rear axle crotch 1, described saddle sleeve pipe has vertical beam 2, described front fork sleeve one side is provided with head and the tail and connects the double oblique beams of encircling mutually, the bending part top of the upper beam 6 in described double oblique beams is connected with reinforced plate 5, between described reinforced plate and vertical beam, be connected with tie-beam 4, described axis sleeve pipe is located at rear axle crotch lower end, underbeam 9 ends in described rear axle crotch lower end and double oblique beams are hinged by hinge 10, between described rear axle crotch upper end and reinforced plate, are connected with damping spring.

Described in this example, between double oblique beams, front portion is provided with strip rib 8.Increase car body strength.

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.
