Abstract
The utility model relates to a front fork of a bicycle, which comprises a front fork frame, a vertical bar and a hole, wherein one end of the vertical bar is connected with the front fork frame, the other end of the vertical bar is connected with a bibcock of the bicycle, and a center position of the front fork frame is equipped with the hole which is used to install a front wheel brake system. The utility model is characterized in that the vertical bar comprises a vertical supported bar and a damping device, wherein the vertical supported bar is fixedly arranged on the center position of the front fork frame, one end of the damping device is sleeved on the vertical supported bar, the other end can be fixedly connected with the bibcock, thereby achieving the purpose of damping. Because the vertical bar can be stretched, the bibcock of the bicycle can be effectively damped, the damping effect is excellent, the use is comfortable, the structure is simple, the process is easy, and the installment and the maintenance are convenient.
Description
Technical field
The utility model relates to a kind of bicycle front fork.
Background technology
Existing bicycle front fork comprises front forked frame, an end be connected with front forked frame the other end can with handle-bar bonded assembly montant.Montant is a straight tube, and it does not have Telescopic, runs into when jolting the road surface, and handle-bar can produce vibrations, and feel is very uncomfortable.
The utility model content
The utility model overcomes the deficiencies in the prior art and provides a kind of montant to stretch, the bicycle front fork that can actv. handle-bar be carried out damping.
In order to achieve the above object, the utility model is achieved in that it is a kind of bicycle front fork, comprises front forked frame, an end be connected with front forked frame the other end can with handle-bar bonded assembly montant; The hole that wheel brake system is used before the center of front forked frame is provided with installation; It is characterized in that: montant comprises the fixing perpendicular pole that is located at the front forked frame center, an end be set in perpendicular pole go up the other end can with leading shock absorption device of captiveing joint, thereby reach the damping purpose.
Described shock absorption device comprises the threaded sleeve pipe of appearance, registration arm, is set in outer damping spring of sleeve pipe and the pipe link that can captive joint with sleeve pipe; Sleeve pipe axially cooperates by key and groove with registration arm, thereby it can not radially be rotated, and registration arm is fixed on perpendicular pole by fastener, but sleeve pipe relative positioning tubular axis to up-and-down movement, registration arm cooperates with groove by key with perpendicular pole, and it can not radially be rotated.
Be positioned on the described perpendicular pole sleeve pipe below be provided with and support the pad that the damping spring bottom is used, on sleeve pipe, be provided with and support first nut that damping spring top is used.
Described pipe link is connected with sleeve pipe by second nut, on pipe link, be provided with the step that itself and sleeve pipe get loose that prevents that cooperates with second nut, sleeve pipe and pitman shaft be to cooperating by key and groove, thereby it can not radially be rotated, and is provided with the tooling hole that inserts and extract pipe link thereon.
The utility model advantage compared with prior art is, because montant can stretch, can carry out damping to handle-bar by actv., and shock-proof effect is good, uses comfortable, simple in structure, handling ease, installation and easy to maintenance.
Description of drawings
Fig. 1 is a block diagram of the present utility model;
Fig. 2 is the exploded view of Fig. 1;
Fig. 3 is the cross sectional drawing that the shock absorption device of Fig. 1 combines with perpendicular pole.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 1, 2, its a kind of bicycle front fork, comprise front forked frame 7, one ends be connected with front forked frame the other end can with handle-bar bonded assembly montant; The hole 83 that wheel brake system is used before the center of front forked frame is provided with installation.Montant comprise fixing perpendicular pole 8, one ends that are located at the front forked frame center be set in perpendicular pole go up the other end can with leading shock absorption device of captiveing joint, thereby reach the damping purpose.
Shown in Fig. 2,3, in the present embodiment, shock absorption device comprises the threaded sleeve pipe 3 of appearance, registration arm 9, is set in outer damping spring 5 of sleeve pipe and the pipe link 1 that can captive joint with sleeve pipe; Sleeve pipe axially cooperates by key 31 and groove 91 with registration arm, thereby it can not radially be rotated; Be provided with tapped hole 82 on perpendicular pole 8, registration arm is by being fixed on fastener 10 and cooperating of hole on the perpendicular pole, and registration arm also cooperates by key 92 and groove 81 with perpendicular pole, thereby it can not radially be rotated; But sleeve pipe 3 relative positioning tubular axis are to up-and-down movement, and this sleeve pipe cooperates the purpose that can reach vertical damping with damping spring.Be positioned on the perpendicular pole 8 sleeve pipe 3 below be provided with and support the pad 6 that damping spring 5 bottoms are used, on sleeve pipe, be provided with and support first nut 4 that damping spring top is used, thereby make the damping spring axial limiting.Pipe link 1 is connected with sleeve pipe 3 by second nut 2, on pipe link, be provided with the step 12 that it declines and take off from sleeve pipe that prevents that cooperates with second nut, sleeve pipe and pitman shaft are to cooperating by key 31 and groove 13, thereby it can not radially be rotated, on pipe link, be provided with and prevent its axially movable step 12, thereby under the effect of second nut, pipe link cannot be extracted out, be provided with the tooling hole 11 that inserts and extract pipe link thereon.
