Fig. 3 is the cutaway view of embodiment of the present invention locking folding joint;
Fig. 4 is the cutaway view of embodiment of the present invention locking folding joint fine tuning structure;
Fig. 5 is the schematic perspective view after the embodiment of the present invention is laid down vertical tube and top connection.
The specific embodiment
As shown in Figures 1 to 5, what one embodiment of the invention provided is for the self-locking folding joint between folding front wheel fork for bicycle and handle vertical tube, it comprises: the vertical tube 1 be connected with bicycle handle, the top connection 2 be connected with vertical tube 1 lower end, the lower adaptor 3 be connected with the standpipe of front fork upper end, the rotatable handles 4 for top connection 2 and lower adaptor 3 are linked into an integrated entity.The present embodiment upper, lower adaptor 2, 3 and handle 4 connect into one by a hinge axis 5 and can fold and open joint, wherein, in the inner chamber of lower adaptor 3, the inwall of relative hinge axis 5 is provided with wedge-shaped impression 31, the lower surface of top connection 2 is provided with the locking flange 21 of the wedge shape that can insert wedge-shaped impression 31, the present invention also comprises the oblate axle 6 of bias between the hinge axis mounting hole 32 of the hinge axis mounting hole 41 of being located at hinge axis 5 and handle and lower adaptor, hinge axis mounting hole 41 and eccentric oblate axle 6 form fit of handle, eccentric oblate axle 6 forms the integrated synchronous rotations with handle 4 after inserting the hinge axis mounting hole 41 of handles, jointed shaft 5 is connected with top connection 2 through eccentric oblate axle 6, , and eccentric oblate axle 6 can rotate relative to the hinge axis mounting hole 32 of lower adaptor 3.
In another embodiment of the present invention, as Fig. 3 to Fig. 5 shows, can also on the wall body of hinge axis 5 one sides of lower adaptor 3, be provided with a self-lock rod that can move up and down 9 along lower adaptor 3 direction of axis line, the parallel lower adaptor 3 direction of axis line settings of this self-lock rod 9.When self-lock rod 9 moves up, can limit rotating counterclockwise of handle 4, when moving down, remove the restriction that handle 4 rotates counterclockwise when self-lock rod.Rotation by restriction or releasing handle 4, thereby reach the purpose that restriction locking flange 21 transverse shiftings are deviate from wedge-shaped impression 31, encounter handle 4 when accident, also can not make handle 4 rotate counterclockwise and the misunderstanding lock situation of folding joint occurs, make the locking of folding joint very reliable.In the present embodiment, self-lock rod 9 is located in the wall body of lower adaptor 3 of corresponding handle 4 lower ends, laterally be provided with a waist-shaped hole 33 in the wall body of the lower adaptor 3 of self-lock rod 9 bottoms, one handle stretches out described waist-shaped hole 33, the lower surface of self-lock rod 9 is provided with a spring 10, and handle 4 lower ends are provided with and hold the self-locking groove 42 that self-lock rod 9 inserts, and by handle, self-lock rod 9 are moved up and down, when self-lock rod 9 moves up, insert the self-locking groove 42 of handle; Handle comprises: be located at the interior hollow safety hook 11 of described waist-shaped hole 33, be set in the screw 12 that the front end in this safety hook 11 is connected with the lower thread of described self-lock rod 9.In practical application, also can design according to different needs other handgrips.
More optimize, as shown in Figure 2, in yet another embodiment of the invention, also being provided with a fine tuning structure in top connection 2 comprises: top connection 2 inner chamber middle parts are provided with a back-up block 22, one connecting rod 7 one ends are connected with back-up block 22 and the other end is connected with a side of a cushion block 8, and these cushion block 8 opposite sides and handle 4 bottom butts, in the present embodiment, connecting rod 7 is an adjusting bolt, and an end of this adjusting bolt is threaded and the cushion block 8 of other end butt with back-up block 22.In practical application, can select different connection modes to connect pipe link 7 and back-up block 8.
Carry out the longitudinal travel of regulating connecting rod 7 relative back-up blocks 22 by rotating adjusting bolt-connecting rod 7, thereby adjust the side-play amount of handle 4 and hinge axis 5 axial lines, so that adjust the depth displacement that locking flange 21 inserts wedge-shaped impression 31, finally reach the purpose of top connection 2 and lower adaptor 3 locking safely and reliably.
As Fig. 1 to Fig. 3 shows, first top connection 2 clockwise rotated and close with lower adaptor 3, again handle 4 is rotate in place to the direction up time near vertical tube 1, the oblate axle 6 of bias now together clockwise rotates in company with handle 4, hinge axis 5 is done and is clockwise rotated around the axis of the oblate axle 6 of bias, make top connection 2 move right, so that locking flange 21 inserts in the wedge-shaped impression 31 of lower adaptor 3 gradually simultaneously, thus by top connection 2 and lower adaptor 3 fixing and lockings in aggregates-folding joint expendable locked.Simultaneously, self-lock rod 9 moves up under the elastic force effect of spring 10, and inserts in the self-locking groove 42 of handle 4, thus the secondary locking of the rotate counterclockwise-folding joint of restriction handle 4.
As Fig. 2 to Fig. 5 shows, when needs are opened top connection 2 and lower adaptor 3, press safety hook 11 downwards, drive self-lock rods 9 by screw 12 and move down the self-locking groove 42 that breaks away from handle, so that the rotating counterclockwise of the handle 4 that lifts restrictions.Again handle 4 was rotated to the direction inverse time away from vertical tube 1, make locking flange 21 transverse shiftings deviate from wedge-shaped impression 31, thereby remove the fixing and locking of top connection 2 and lower adaptor 3, rotate realization " folding " with the top connection 2 of vertical tube 1 around oblate relative 3 inverse times of lower adaptor of axle 6 of bias.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
