Specific embodiment

Further to illustrate technical means and efficacy that the utility model is taken by the predetermined purpose of utility model of realization, Attached drawing and preferred embodiment are fastened below, to foundation specific embodiment of the present utility model, structure, feature and its effect, in detail It describes in detail bright as after.

Embodiment 1

As shown in figure 5, using 11 place side of left half pedestal as left side, using side where right half pedestal as right side；With attachment base 1 First mounting portion, 13 position is inside, using the attachment base away from the first mounting portion 13 as outside.

As shown in Figs 1-4, a kind of dismountable attachment device of the utility model, including left half pedestal 11, right half pedestal 12, Steering shaft 6 in connection ring 2 and vehicle bar；Half pedestal 11 of a left side and right half pedestal 12 installation form attachment base 1；It is installed on attachment base 1 Connection ring 2；Shaft 6 is mounted in attachment base 1；Connection ring 2 is fixed on the top of steering shaft 6.

As shown in figure 5, half pedestal 11 of a left side and right half pedestal 12 are equipped with longitudinal perforative through slot in connecting side；Left half pedestal 11 are equipped with protrusion with same position of right half pedestal 12 in the middle part of longitudinal through slot；The bottom end of a left side half pedestal 11 and right half pedestal 12 Groove is equipped with to what the position of protrusion was recessed from connecting side from inside to outside；The cylindrical curved surface of right half pedestal 12, which is equipped with, to be used for The cylindricality counterbore of left half pedestal 11；Half pedestal 11 of a left side and right half pedestal 12 are removably mounted to attachment base 1；11 He of left half pedestal The through-hole of the corresponding composition of protrusion on right half pedestal 12 is the second mounting portion 14；The protrusion of a left side half pedestal 11 and right half pedestal 12 The through slot of portion upper end the first mounting portion 13 of corresponding composition；Left half pedestal 11 composition third peace corresponding with the groove on right half pedestal 12 Dress portion 15；The cross sectional dimensions of third mounting portion 15 is greater than the cross sectional dimensions of the second mounting portion 14, therefore in the first mounting portion 13 and second mounting portion 14 junction formed step 17.

Further, the cross section of the through slot of above-mentioned left half pedestal 11 and right half pedestal 12 is circle；Left half pedestal 11 and the right side The cross section outer ledge of half pedestal 12 is semicircle.

As shown in fig. 6, attachment base 1 is in the apertured cylindrical body in junction；The top surface of attachment base 1 is equipped with for installing The blind hole of connection ring 2；It is set on attachment base 1 there are two extending through the through-hole 16 of the first mounting portion 13 and the second mounting portion 14, two A through-hole 16 is in longitudinal arrangement.

As shown in fig. 7, connection ring 2 is a Thin Disk, it is equipped with circular through hole among connection ring 2, the four of the circular through hole Week is equipped with the bellmouth for being fastened on attachment base 1；On the side disc of connection ring 2, convex block is equipped with along circular through hole edge 21。

As shown in figure 8,6 pedestal of steering shaft on vehicle bar connects for bicycle or the vehicle bar of scooter or electric bicycle Connect front fork 7；The inside of steering shaft 6 is hollow；The top of steering shaft 6 is equipped with shaft part 1, shaft part 2 61 and shaft part 3 62, turns Connection ring mounting groove 63 is radially offered to the top surface of axis 6.

It illustrates, steering shaft 6 is equipped with notch 64 below the position for being arranged bowl group 5；The opening of notch 64 is towards wheel Preceding line direction；Bulb plunger screw or other screws penetrate into notch 64 from the front side outer surface of connector 9, so that steering shaft Control stick where 6 will not 360 degree rotations, in a certain range by the rotation restriction of steering shaft 6.

Half pedestal 11 of a left side and right half pedestal 12 pass through cylindricality counterbore using fastener and the two link together, left half pedestal 11 can have the gap when connecting with right half pedestal 12, and the presence in gap is more advantageous to 6 sets of the steering shaft inside in attachment base 1.

Steering shaft 6 is located between left half pedestal 11 and right half pedestal 12；Shaft part 1 is mounted in the first mounting portion 13, axis Section 2 61 is installed in the second mounting portions 14, and the diameter of the shaft part 1 is 0.1mm bigger than the diameter of first mounting portion 13 ~ 5mm；The diameter of the shaft part 2 61 is 0.1mm ~ 5mm bigger than the diameter of second mounting portion 14, so steering shaft 6 is just blocked Step 17, so that attachment base 1 can not integrally leave steering shaft 6；Shaft part 3 62 is located in third mounting portion 15, shaft part 3 62 it is straight Diameter is less than the diameter of third mounting portion 15；Vehicle bar is given in the inner hollow position of circular through hole face steering shaft 6 in connection ring 2 Electric wire connection provide space；Convex block 21 is stuck on connection ring mounting groove 63, so that connection ring 2 is connected with steering shaft 6.

Further, the through slot cross section on above-mentioned left half pedestal 11 and right half pedestal 12 can be other shapes, and shaft part One 60 shape then matches with the first mounting portion 13；The shape of shaft part 2 61 matches with the second mounting portion 14.

Steering shaft 6 is successively cased with small round nut 3, gasket 4 and bowl group 5 from the bottom up；Small round nut 3 is installed to be installed into third In portion 15, the bottom of attachment base 1 is resisted against 4 upper surface of gasket, and gasket 4 is mounted in bowl group 5.

It further illustrates, attachment base 1 is pressed on gasket 4 using own wt, prevents the loosening due to gasket 4 from causing to turn to The loosening of axis 6, so that go to action can not accurately be passed to front fork 7 by steering shaft 6, to influence vehicle bar rotation direction.

Column on vehicle bar is arranged and is fastened on the outer surface of a left side half pedestal 11 and right half pedestal 12 using screw.

It illustrates, according to the use occasion of attachment base 1, the cross section outer ledge of left half pedestal 11 or right half pedestal 12 It can be set to non-circular.

As shown in figure 9, head of screw is equipped with protection cap 8 in the position of leg surface, protection cap 8 is for wrapping up head of screw.

Illustrate, left half pedestal 11 and the right side half pedestal 12 connecting end surface on can be respectively equipped with flange and with it is convex Edge docks bayonet.

When user adjusts direction of traffic, column is passed to go to action on the attachment base 1 being attached thereto, attachment base 1 Connection ring 2 is driven, connection ring 2 and attachment base 1 make 6 adjustment direction of steering shaft together；Steering shaft 6 is again by the energy transmission of rotation To front fork 7, front fork 7 changes the direction of motion of front-wheel, to complete the transmitting of a series of vehicle bar direction adjustment movement.

According to the utility model embodiment, attachment base 1 and connection ring 2 are installed in vehicle bar steering shaft 6, are on the one hand used for Gasket 4 is pushed down, to prevent the loosening of steering shaft 6, influences the timeliness and accuracy of the steering of vehicle bar；On the other hand, when steering angle ratio When larger, attachment base 1 can also effectively prevent steering shaft 6 to collide with column, to reduce the service life of vehicle bar.
