Description
Technical field
The utility model relates to the anti-vibration structure improvement of bicycle front fork, especially relates to a kind of structure that the Shock absorber function lock of bicycle front fork can be pulled.
Background technology
The front-wheel of existing bicycle is travelling and turning in order to the control bicycle mainly, so mainly be being connected between the front-wheel of bicycle and the handle basically by front fork and faucet, so that when bicycle handle turns to, can allow front-wheel rotate freely; On the other hand, the driving in the process of Regular Bicycle, the mode that rider must soar with buttocks is to avoid the human discomfort of road shock.
Therefore, emphasize to climb the mountain, how the bicycle of cross-country function can install Shock absorber between the transom (being front fork) of its handle and front-wheel,, thereby rider can be had drive comfortable preferably and control performance with vibrations by Shock absorber absorption front-wheel.
Existing a kind of bicycle front fork with incabloc function is constructed as shown in Figure 1.Wherein, the front fork tube group 10 of bicycle has two front fork tubes 11 that are provided in bicycle front-wheel both sides respectively, and its Shock absorber 30 is located in two front fork tubes 11.Front fork vertical bar 20 bottoms of bicycle then are provided with a shoulder seat 21, and these shoulder seat 21 utilization shoulders cover the 23 corresponding telescopic pipes 22 that stretch into two front fork tubes 11 with two and lock mutually, and the top inner side of two front fork tubes 11 constitutes connection by a bridge joint beam 12.Thereby, elastic reaction that can be by Shock absorber 30, allow between front fork tube group 10 and the front fork vertical bar 20 can telescopic slide the corresponding activity of mode, and then allow whole front fork have the effect of shock-absorbing.
Yet when the pedal of the mode treadled cycle that soars with buttocks as the cycling person or climbing, it is also wished and can increase by the strength that imposes on pedal, to reach the purpose of heavy pedal; Yet Shock absorber provides the telescopic action of two devices of front fork body, can therefore absorb the application force that rider imposes on pedal, allows rider more feel painstaking on the contrary when pushes pedals.
Based on above reason, how existing many bicycles with Front fork vibration abatement function can be provided with the members of modulated pressure flow at the Shock absorber place, to utilize control Shock absorber hydraulic flow or the mode of closing the hydraulic oil duct reaches the effect of slowing down the Shock absorber effect; But so structure is formed not only comparatively complexity, and cost is higher, and when reality was used, the switching effect of its Shock absorber function also was not so good as the ideal of expection.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of lock of automatic shock-proof front fork structure of pulling, its front fork vertical bar function lock that can allow the rider select the Front fork vibration abatement device is connect is pulled, allowing front fork connect front fork vertical bar can't be movable mutually, avoids consuming the application force of rider pushes pedals.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of lock of the automatic shock-proof front fork structure of pulling is provided, its bicycle is that the junction of arbitrary front fork tube and front fork vertical bar is provided with shock absorbing apparatus among the front fork tube group, be arranged with one at another front fork tube with the corresponding moving position place of front fork vertical bar and lock the structure of pulling, this lock structure of pulling is installed in one of this front fork vertical bar end, and can make and enter or withdraw from this front fork active state is changed; This lock is pulled to construct and is comprised that one is sheathed on axle and the stationary pipes in this front fork tube, this axle one end is located in one of front fork vertical bar end, the other end stretches into and is provided with a tip body in the stationary pipes, this stationary pipes is provided with the longitudinal slot that can supply this tip body to vertically move, and communicate with longitudinal slot and can be for the transverse groove of tip body side travel, downside of fixed tube then is fixed in downside of front cross tube, can drive the position of tip body in longitudinal slot or transverse groove by live spindle.
The beneficial effects of the utility model are: enter under the state of front fork at this lock structure of pulling, front fork tube and front fork vertical bar are can allow front fork tube and the front fork vertical bar can't corresponding activity by the lock structure of pulling, thereby reach the Shock absorber function are locked the purpose of pulling.

The specific embodiment
The lock of the utility model automatic shock-proof front fork structure of pulling, mainly as shown in Figure 2, bicycle front fork pipe group 10 and front fork vertical bar 20 are two device bodies that Shock absorber 30 is connect.Wherein, front fork tube group 10 has two front fork tubes 11 that are provided in bicycle front-wheel both sides respectively, and its Shock absorber 30 is in the front fork tube 11 located therein, locks the structure 40 of pulling and then is located in another front fork tube 11.The bottom of front fork vertical bar 20 is provided with a shoulder seat 21, these shoulder seat 21 utilization shoulders cover the 23 corresponding telescopic pipes 22 that stretch into two front fork tubes 11 with two and lock mutually, wherein there is a dust protecting cap 24 both appropriate locations, junction, please enter to prevent dust simultaneously with reference to shown in Figure 3.The top inner side of two front fork tubes 11 constitutes connection by a bridge joint beam 12.
During concrete enforcement, as shown in Figures 2 and 3, lock the structure 40 of pulling and constituted with stationary pipes 42 by an axle 41 that is sheathed in this front fork tube 11.This axle 41 is inserted in telescopic pipe 22 back and is inserted in shoulder in regular turn by the top side and cover 23 and adjustment part 43, utilizes locations 51 to pass adjustment part 43 again and axle 41 tops lock mutually.These axle 41 other ends stretch into and are provided with a tip body 44 in the stationary pipes 42, and 42 of axle 41 and stationary pipes are arranged with a lining 45.This stationary pipes 42 is provided with the longitudinal slot 421 that can vertically move for this tip body 44, and communicates with longitudinal slot 421 and can be for the transverse groove 422 of tip body 44 side travels.This transverse groove 422 can be as shown in Figure 3 by longitudinal slot 421 to a side vertical extent, perhaps as shown in Figure 4, to the both sides vertical extent, front fork tube 11 bottom sides then are fixed in stationary pipes 42 bottom sides by longitudinal slot 421.Certainly, this fixed form can utilize locations 51 that stationary pipes 42 and front fork tube 11 are locked mutually as shown in Figure 3, or utilizes stationary pipes 42 bottom sides and front fork tube 11 bottom sides to form the locating piece 423 and the positioning groove 111 that can be involutory, its form can make it engage the location mutually as Fig. 5 or shown in Figure 6.
During use, as shown in Figure 7, can be via the action of simple turn adjustment part 43, allow axle 41 make the state change that its tip body 44 falls within longitudinal slot 421 or transverse groove 422, so can be as shown in Figure 8, allow tip body 44 be the state that enters transverse groove 422, and constitute the fixed connection of front fork tube group 10 and front fork vertical bar 20 by axle 41, and can really the lock of the Shock absorber function between front fork tube group 10 and the front fork vertical bar 20 be pulled, allow front fork tube group 10 and front fork vertical bar 20 be unlikely to telescopic slide, avoid consuming the application force of rider pushes pedals.
Conversely, when rider need recover the function of Shock absorber, also must be via the action of simple turn adjustment part 43, allow axle 41 make the state change that its tip body 44 falls within longitudinal slot 421, tip body 44 can be done in longitudinal slot 421 to move up and down, as shown in Figure 2, can discharge the connection effect of 41 pairs of front fork tube groups of axle 10 and front fork vertical bar 20, fast speed recovers the function of Shock absorber.
