When needing foldable handlebar, first connecting portion 1 will be sheathed on, the handlebar set casing 7 outside 2 hinged place of second connecting portion
It removes, when second connecting portion 2 is rotated relative to first connecting portion 1, under the extruding of spring, the surface of the engaging portion of ball 3 is inevitable
It is slided on the surface of first connecting portion, but is unlikely to that second connecting portion 2 is hindered to rotate, it is obvious that engaging portion 301 was slided
Track necessarily one section of circular arc, and the counterbore 101 being set in first connecting portion also is located on this section of circular arc, therefore second connecting portion
When 2 rotations to certain position, engaging portion is in conjunction with the opening of one of counterbore 101, then the rotation of second connecting portion is hindered
The diameter of power, ball 3 is greater than 101 diameter of counterbore, and avoidable ball is fallen into counterbore 101；The counterbore of ball 3 and different location
101 combination determines first connecting portion 1, second similar to multiple gears are arranged in the foldable structure of handlebar convenient for user
The angulation in folding process of interconnecting piece 2, and after forming the folding angles, the engaging portion of ball 3 be located at this
Counterbore 101 combines, and prevents first connecting portion 1 under no external force relative to the unordered rotation of second connecting portion 2, thus, herein
The engaging portion of ball 3 can play position-limiting action after being combined with counterbore 101, need to change first connecting portion 1, second connecting portion again
When folding angles between 2, apply external force, rotates first connecting portion 1.
In order to facilitate the installation of with disassembly holding screw 5, spring 4 and ball 3, screw thread is equipped in the radial through-hole 201
Section is equipped with the external thread section combined with thread segment on 5 outer wall of holding screw.
In normal use, the hinge point of first connecting portion 1, second connecting portion 2, the position both as mutually folded
Handlebar set casing 7 is slid into, the eccentric handle 6 being set on handlebar set casing 7 is compressed.
In the present embodiment, the first connecting portion 1, second connecting portion 2 are hinged by articulation piece, to facilitate installation, nothing
Damage disassembly, articulation piece are used with flowering structure: it includes the first screw 10, and the second screw 11, second screw 11 is by the second spiral shell
Cap 1101, the second screw rod 1102 are made of one piece, and axial threaded hole 1102a is equipped in the second screw rod；Second screw rod
1102 front end enters in first connecting portion 1 after passing through second connecting portion 2, the rear end of the second nut 1101 and the second screw rod
In second connecting portion 2；First screw 10 is made of one piece by the first screw rod 1001 and the first nut 1002, the first screw rod
1001 are inserted in the second screw rod 1102 and are connected through a screw thread with the second screw rod.
Radially be equipped in order to install articulation piece, in the first connecting portion 1 first sinking seat 102 and with the first sinking seat
The first through hole of 102 connections；The for being radially equipped with the second sinking seat 202 in second connecting portion 2 and being connected to the second sinking seat
Two through-holes 203；Second screw rod, 1102 front end enters first after sequentially passing through the second sinking seat 202 and the second through-hole 203
In through-hole, the first nut 1002 is located in the first sinking seat 102 and the first nut lower surface leans with the first sinking seat bottom surface；
Second nut 1101 is located in the second sinking seat 202 and the second nut lower surface leans with the second sinking seat bottom surface.
First screw 10, the second screw 11 forms a pair can be to the Screw of lock, i.e. first connecting portion 1 and the second connection
Portion 2 is connected using to lock Screw, and is fully sunk in and is set respectively to the first, second nut 1002,1101 of lock Screw
In in the sinking portion in 2 surface of first connecting portion 1 and second connecting portion, the benefit designed in this way is, by first connecting portion 1,
Two interconnecting pieces 2 and to the composition of lock bolt and nut can using to the axis that forms of lock bolt and nut as the handlebar connector group of rotary shaft
Part can slide into handlebar set casing 7, to realize that handlebar joint assembly includes holding screw 5, spring 4 and ball 3, hide not sudden and violent
It exposes outside, reaches beautiful, succinct, stealthy purpose.
The first secure localization slot 103 is equipped in the side wall of the first connecting portion, be equipped in the side wall of second connecting portion with
Second secure localization slot 204 of the first safety groove connection.First secure localization slot 103, the second secure localization slot 204 have been one
Secure localization effect, it is 4 millimeters or the positioning screw (not shown) of other diameters that a diameter is arranged in eccentric handle 6, partially
After compaction, positioning screw can protrude into the first secure localization slot 103, in the second secure localization slot 204 to heart handle 6 just, in this way
Entire handlebar will not move left and right, although moving left and right the almost impossible generation of such case, but if having used this structure,
Handlebar can not move left and right, which plays the role of dual fail-safe.
In conclusion the utility model can prevent at handle bar folding loosen, moreover, handle bar folding at an angle when, can
It maintains a relatively stable state.
Although depicting the utility model by embodiment, it will be appreciated by the skilled addressee that the utility model has perhaps
Shape changeable and variation without departing from the utility model spirit, it is desirable to the attached claims include these deformation and change without
It is detached from the spirit of the utility model.
