Abstract

The utility model relates to a bicycle seat stand pipe which is molded by composite materials. The stand pipe is inserted into a shaft tube of a bicycle frame. A locking member at the end head of the shaft tube is locked outside the stand pipe. The interface of the stand pipe and the locking member is provided with a long strip-shaped groove, and a reinforcing piece is stuck and arranged in the groove for positioning. The reinforcing piece comprises an outer layer and an inner layer, wherein the outer layer of the reinforcing piece is flaky and is made of metal materials, and the inner layer of the reinforcing piece is made of composite materials. The utility model can prevent the stand pipe from being damaged so as to extend the service life of the bicycle seat stand pipe.

Description

Order driving seat cushion vertical tube

[technical field]

The utility model is about a kind of bicycle, particularly about a kind of bicycle saddle cushion vertical tube.

[background technology]

Automobile, though the use of motor bike brings people comfort feature in trip, but institute's exhaust gas discharged also causes the pollution of air, therefore each big city, the world in recent years, the exclusive lane of bicycle all is set, except reducing the pollution, and can obtain the effect of sport and body-building, known bicycle 1 is general as shown in Figure 1, all be front end at a vehicle frame 11 leader 12 that is pivoted, the handle 12 belows front fork 13 that is pivoted, these front fork 13 lower ends front-wheel 14 that is pivoted, the rear of vehicle frame 11 trailing wheel 15 that then is pivoted, and the upper shaft of vehicle frame 11 is established a vertical tube 16 between front-wheel 14 and trailing wheel 15, but these vertical tube 16 termination abutment pads 17 are provided with, and a pedal 18 is set at front-wheel 14 and 15 of trailing wheels, this pedal 18 can be done the rotation in original place, and pedal 18 also links with transmission component 19 and trailing wheel 15, so after stepping on pedal 19 rotations, can drive trailing wheel 15 rotations through transmission component 19, rotate synchronously and drive front-wheel 14, to make bicycle 1 reach the purpose of advancing, at previous bicycle materials used is metallic material mostly, though have preferable rigidity intensity, relative, the overall weight of bicycle is also heavier, cause speed significantly to improve, simultaneously also be unfavorable for moving, and along with the progress of material science, along with carbon fiber, after composite materials such as glass fibre are developed, the each several part element of existing bicycle, except needs lock the place, can say all and make with composite material, can significantly alleviate the weight of bicycle by this, but and actv. improves the speed of bicycle.And supply seat cushion 17 spiral shells are established the vertical tube 16 of fixed bit, please cooperate Fig. 2,3 consult, this vertical tube 16 is to plug together in being extended in the central siphon 111 that protrudes by vehicle frame 11, and utilize central siphon 111 termination openings shape locking components 112, make vertical tube 16 locking location, and can adjust the fixed position of vertical tube 16, to reach the purpose of adjusting seat cushion 17 height, but because locking component 112 is that metallic material is made, vertical tube 16 is then made for composite material, therefore behind the locking location, the opening of locking component 112 is established under the closed situation at spiral shell, its two termination will be resisted against the interface place with vertical tube 16, is under the situation of composite material at locking component 112 for metallic material vertical tube 16, vertical tube 16 these interfaces then, because rigidity intensity is lower, will wear away the phenomenon of damage, after causing using a period of time, be easy to produce the problem that wrecks, for this reason, there is the dealer to be improved, please cooperate Fig. 4,5 consult, it is at the two termination interfaces of vertical tube 2 with locking component 31 openings of central siphon 3, offer the groove 21 of a strip, fitting in groove 21 places with the reinforcing chip 22 of a strip again is combined as a whole, this reinforcing chip 22 is to make with plastic material, mat reinforcing chip 22 is the design of strip, when adjusting when highly making vertical tube 2 flexible, all can by reinforcing chip 22 for two terminations of locking components 31 openings against, avoid the damage of vertical tube 2 these interfaces, and because reinforcing chip 22 only is to make with plastic material, its rigidity intensity still is lower than the metallic material of locking component 31, so that effect is limited, the situation that can not avoid fully damaging takes place, so how under the prerequisite of not gaining in weight, actv. improves the rigidity intensity of vertical tube 2 these interfaces as far as possible, reality is a current dealer problem extremely to be solved.

[utility model content]

The purpose of this utility model is to provide a kind of bicycle saddle cushion vertical tube, and its damage that can avoid vertical tube is to prolong the service life of bicycle saddle cushion vertical tube.

In order to achieve the above object, the utility model provides a kind of bicycle saddle cushion vertical tube, this vertical tube is to be made by composite material, this vertical tube plugs together on the central siphon of cycle frame, the locking component of this central siphon termination is locked on this vertical tube outside, be provided with the groove of a strip in the interface of this vertical tube and this locking component, a reinforcing chip is attached at location in this groove, it is characterized in that:

This reinforcing chip comprises an outer and internal layer, and the skin of this reinforcing chip is laminar, and makes for metallic material; The internal layer of this reinforcing chip then is to make with composite material.

In sum, bicycle saddle cushion vertical tube of the present utility model, by establishing a groove in the interface of vertical tube and central siphon locking, and the outer metallic material internal layer for as thin as a wafer that is sticked in groove is the reinforcing chip of composite material, and has preferable rigidity intensity, plug together in the central siphon busy hour fixed of locking at vertical tube, make the locking component of central siphon be resisted against the skin of reinforcing chip, the damage of avoiding vertical tube is to prolong the life-span of using.

[specific embodiment]

Be the effect that enables to be easier to understand structure of the present utility model and can reach, describe in detail as the back with the preferred embodiment conjunction with figs. now:

The utility model is meant the vertical tube 4 with composite material forming, at first see also Fig. 6, as the person of commonly using, this vertical tube 4 plugs together on the central siphon 5 of cycle frame, the locking component 51 of these central siphon 5 terminations is locked on this vertical tube 4 outsides, be provided with the groove 41 of a strip in this vertical tube 4 and the interface of this locking component 51, one reinforcing chip 6 is attached at location in this groove 41, and make groove 41 places form one concordant, please cooperate again and consult Fig. 7, this reinforcing chip 6 is by skin 61 and internal layer 62 be combined intos, outer 61 for laminar and make for metallic material, and internal layer 62 then is to make with composite material, and can be after being attached at groove 41, can be a firm bonding state, the not phenomenon that can come off with vertical tube 4.

The utility model is made up of the skin 61 of metallic material and the internal layer 62 of composite material by reinforcing chip 6, outer 61 is under the thin slice state, can drop to the weight that increases minimum, and can the moving velocity of bicycle not exerted an influence, be metallic material because of outer 61 simultaneously, can have preferable rigidity intensity, when locking component 51 lockings, two terminations of its opening are to be resisted against outer 61, then be all under the metallic material, just can stop the abrasion that vertical tube 4 causes because of locking fully, but actv. prolongs the service life of bicycle saddle cushion vertical tube.
