Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and it be as follows to coordinate accompanying drawing to describe in detail:
Referring to Fig. 1, a kind of mountain bike shock-absorbing front fork, including vertical tube of front fork 1 and damping crotch 2, the top of described damping crotch 2 is fixing with the lower end of described vertical tube of front fork 1 to be connected. Described vertical tube of front fork 1 has the centre bore 1-1 of lower ending opening. The bottom of described damping crotch 2 has the slotted eye for installing wheel.
The expansion link 3 that can stretch out it is fitted with from the lower ending opening of described vertical tube of front fork 1 in described vertical tube of front fork 1. The lateral surface of described expansion link 3 has axial slide 3-1, and namely the length direction of axial slide 3-1 is parallel with the axis of expansion link 3. In the present embodiment, the cross section of expansion link 3 is circular, and the diameter of expansion link 3 is less than the diameter 4mm of centre bore.
The lower end of described expansion link 3 is provided with roller 4 by rotating shaft, and roller 4 can rotate around the axis. The axis of described rotating shaft is parallel with the axis of described slotted eye, and namely the axis of rotating shaft is parallel with the axis of the front wheel axle of mountain bike.
The bottom of described vertical tube of front fork 1 is provided with through the radial screw bore in the described interior outside of vertical tube of front fork 1, the position of described radial screw bore is relative with the position of described axial slide 3-1, being fitted with the clamping screw 5 for locking described expansion link 3 by described radial screw bore on described vertical tube of front fork 1, the front end of described clamping screw 5 is stretched in described axial slide 3-1. The effect of clamping screw 5 has two: one to be radial position for fixing expansion link 3; Two is by coordinating, with axial slide 3-1, the circumferential position fixing expansion link 3, and the axis to ensure roller 4 is parallel with the axis of mountain bike front-wheel.
In this utility model, adjustable telescopic rod 3 stretches out the length of vertical tube of front fork 1 to regulate roller 4 and the distance being arranged between front wheel, thus realizing the adjustment to shock-absorbing front fork damping stroke, the existence of roller 4 ensures still to keep normal rotation when mountain bike front-wheel shakes to extreme higher position.
In order to make expansion link 3 and roller 4 can take in the centre bore 1-1 of vertical tube of front fork 1, expansion link 3 and roller 4 in making this novel are hidden when not playing a role, the axial width of described roller 4 diameter less than described centre bore 1-1.
In order to make the roller 4 can with wheel flexible contact, described roller 4 be rubber rollers.
Dropping in order to avoid expansion link 3 is in course of adjustment, the upper end of described expansion link 3 has defining flange 3-2, and the lower end of described vertical tube of front fork 1 has inside limiting section 1-2.
In order to ensure that clamping screw 5 ensures that when locking expansion link 3 axis of roller 4 rotating shaft is parallel with the axis of the slotted eye of damping crotch 2, the front portion of described clamping screw 5 has wedge-shaped part, and the Breadth Maximum of described wedge-shaped part is more than the width of described axial slide.
