Description
[technical field]
The utility model relates to bicycle, especially relates to the flexible structure of adjusting of a kind of bicycle handle.
[background technology]
The front-wheel of Regular Bicycle mainly is to be used for controlling the balance of bicycle and turning to, between the front-wheel of bicycle and the handle mainly is to be connected by front fork, when bicycle handle turns to, can allow front-wheel along with handle is swung, thereby reach the purpose that turns to smoothly and control balance; Therefore, bicycle should be in the middle of the front fork and the midway location of handle constitute and connect, allow the reaction unanimity of brake drum of front wheel right hand and left hand, right steering, avoid causing the difficulty of controlling.
As shown in Figure 1, be Regular Bicycle front fork and handle coupling arrangement stereoscopic figure commonly used; Wherein, the midway location of the front fork 10 of bicycle directly is provided with the core bar 11 of a hollow, and directly be provided with an axostylus axostyle 21 that can correspondingly be inserted in core bar 11 at the midway location of handle stem 20, and green phase closes the locking assembly with core bar 11 and axostylus axostyle 21 lockings, thereby handle stem 20 and front fork 10 are connect.
The structure of latch assembly generally as shown in Figure 1, in the middle of the front fork 10 and axostylus axostyle 21 belows are provided with a spiro connecting piece 13, be provided with a perforation 131 in the axle center of spiro connecting piece 13, other has a bolt 31 to pass perforation 131 and is spirally connected with spiro connecting piece 13, and its spiro connecting piece 13 and the attachment face of axostylus axostyle 21 are the diagonal plane form of corresponding joint, so can core bar 11 and axostylus axostyle 21 be locked, thereby stem 20 and front fork 10 are connect by bolt 31.
But coupling arrangement commonly used can't be adjusted the height of stem, that is the bicycle of same size can feel that handling position is too high or too short because of the difference of driver's stature, and then causes the restriction of applicable object; And the part of its latch assembly is more, package assembly is comparatively complicated, needs to use other instrument bolt could to be locked or loosen.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of bicycle handle the flexible structure of adjusting, and can allow the user adjust the handle height according to need.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: provide a kind of bicycle handle the flexible structure of adjusting, comprise handle, be connected in the stem and the tubulose front fork of handle, the end tube wall of this front fork is provided with dissected valley one, this dissected valley is along the set length that extends axially of this front fork, be provided with the fixing screw thread of section at this position, dissected valley both sides, nut has been threaded on this screw thread, nut screws in the front fork top, one section fixed end is exposed on the front fork top, described screw thread then extends to fixed end, the midway location of stem directly is provided with a telescopic pipe that can correspondingly be inserted in front fork, this telescopic pipe relies on a locking part to be fixedly arranged on the fixed end of front fork, and telescopic pipe can move up and down in front fork, and locking part grips with the front fork lock ring and then with telescopic pipe.
Further improvement in the technical proposal is:
Described locking part is the hoop clip shape structure that a center is provided with a trepanning, and the locking part sidepiece is extended with a pair of folder ear, has one between this folder ear and extends to crack between the trepanning, and a screw rod is arranged between the folder ear.
Described locking part can be the form of quick detach.
Described front fork and telescopic pipe overlaid place are provided with a fixed orifice and long slot bore respectively, wear a connecting element in the described fixed orifice.
The beneficial effects of the utility model are: because the utility model is provided with dissected valley one on the tube wall of the end of front fork, this dissected valley is along the set length that extends axially of this front fork, be provided with the fixing screw thread of section at this position, dissected valley both sides, nut has been threaded on this screw thread, nut screws in the front fork top, one section fixed end is exposed on the front fork top, described screw thread then extends to fixed end, the midway location of stem directly is provided with a telescopic pipe that can correspondingly be inserted in front fork, this telescopic pipe relies on a locking part to be fixedly arranged on the fixed end of front fork, telescopic pipe can move up and down in front fork, the difference of miles of relative movement, the height of telescopic pipe is then different, thereby can adjust the height of handle, and locking part grips with the front fork lock ring and then with telescopic pipe.Loosen locking part and discharge front fork and the effect of telescopic pipe lock ring, and behind the inserting depth between proper transformation telescopic pipe and the front fork, utilize the lock of locking part to pull work again, can reach the purpose of adjusting the handle height easily in order to telescopic pipe and front fork are fixed.
