Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is done into a detailed description.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As depicted in figs. 1 and 2, the invention provides a kind of dislocation doubling folder, comprise and snapping together and the left shell 1 that can relative to each other rotate and right shell body 2, axially cylindrical drum 3 is provided with in left shell 1, at its center, the cylindrical projection 4 arranged in right shell body 2, cylindrical projection 4 is contained in cylindrical drum 3; The plane at the place, edge of left shell 1 and right shell body 2 is inclined-plane, and the axis of cylindrical drum 3 is vertical with the inclined-plane at the place, edge of left shell 1, and the axis of cylindrical projection 4 is vertical with the inclined-plane at the place, edge of right shell body 2; The first radial positive stop 5 is provided with between the shell wall of left shell 1 and cylindrical drum 3, correspondingly be provided with the second positive stop 17 matched with the first positive stop 5 between right shell body 2 with cylindrical projection 4, handle 8 is also fixed on the outside of left shell 1 by the through cylindrical drum 3 of pin 7 and cylindrical projection 4.The arranged outside of left shell 1 has cell body 9, and handle 8 is contained in cell body 9.Handle 8 is rotatably fixed by set pin 10 and pin 7.Outside pin 7, stage clip 11 is equipped with between left shell 1 and right shell body 2.Pin 7 is fixed on the outside of right shell body 2 by captive nut 12.Setting nut 13 is provided with between pin 7 and captive nut 12.The V-type projection 14 cooperatively interacted and groove 6 is disposed radially in left shell 1 and right shell body 2.
In use, first shank 15 of left shell 1 and the second shank 16 of right shell body 2 are welded on two parts vehicle frame needing fold respectively, when vehicle normally uses, as shown in Figure 3, now cylindrical projection 4 is contained in cylindrical drum 3 state of this dislocation doubling folder; If need folding, then open handle 8, dislocation doubling folder is in releasing orientation, as shown in Figure 4, rotate left shell 1 and the position shown in right shell body 2 to Fig. 5, after making the front and back wheel of car be folded into most perfect condition, V-type projection 14 is located in groove 6, then handle 8 is closed card in cell body 9.
Dislocation doubling folder of the present invention, adopt the fit mode locking mechanism of left and right two panels, left shell and right shell body snap together and can relative to each other rotate, the plane at shell rim place is inclined-plane, ensure that and can reach folding dislocation after housing rotates around axle center, inclined-plane, form rational folding effect.Be respectively arranged with positive stop in left shell and right shell body, when fold mechanism reaches using state meeting automatic spacing, only need handle to lock, also only needing handle to lock when fold mechanism reaches folded state can complete folder function.This dislocation doubling folder is skillfully constructed, and structure is simple.As shown in Figure 6, there is the good and safety of the bicycle folding effect of this dislocation doubling folder 18, after folding, space can be saved to greatest extent.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
