The specific embodiment
The vertical tube of front fork of the utility model and the unitized construction of vertical tube include restraints part, a packing assembly on a vertical tube of front fork, a vertical tube, the quick detach assembly,, and restraints part once.This vertical tube is sheathed on this vertical tube of front fork with a sleeve joint hole; This quick detach assembly is located at this vertical tube, in order to this vertical tube is fixed in this vertical tube of front fork; Should go up the bundle part and be located at the top of this vertical tube of front fork; This packing assembly has a loam cake, and the top and the packing that are covered on this vertical tube of front fork on this should be gone up the bundle part; This time bundle part is located at this vertical tube of front fork and is positioned at the root edge of this vertical tube.By the design of this upper and lower bundle spare, can increase integrally-built stability really, this time bundle part can cooperate the vertical tube of different size to carry out the adjustment of position in addition, cooresponding convenience in the use.
In the unitized construction of vertical tube of front fork that the utility model provided and vertical tube, the loam cake of this packing assembly can be fixed in this vertical tube of front fork through the collocation of a bolt and a flower tooth, perhaps also directly spiral shell be located at the top of this vertical tube of front fork.
In the unitized construction of vertical tube of front fork that the utility model provided and vertical tube; This quick detach assembly has a pivot, leader; An and adapter shaft; This pivot is located at an articulated section of this vertical tube pivotly, and an end of this handle has one or two ear and this pivot forms pivot joint, and the two ends of this adapter shaft connect this vertical tube and this pivot respectively.
Following conjunction with figs. is also enumerated following preferred embodiment, is elaborated in order to structure and effect to the utility model.
Please consult Fig. 1 and Fig. 2 earlier; Unitized construction 10 for the vertical tube of front fork 12 and the vertical tube 14 of the utility model first preferred embodiment; Include bundle part 30, a packing assembly 40 on a vertical tube of front fork 12, a vertical tube 14, a lining 16, the quick detach assembly 20,, and restraint part 50 once.
One end of vertical tube 14 is used the handgrip assembling for bicycle; The other end has a garter spring 141, and garter spring 141 end wises run through a sleeve joint hole 142, in order to the top of sheathed vertical tube of front fork 12; The two ends of garter spring 141 extend outward an articulated section 144 and an installation portion 146 respectively again; In addition, as shown in Figure 3, the root edge of garter spring 141 stretches out a rotating limit block 148 downwards.
As shown in Figure 3, lining 16 is located in the sleeve joint hole 142 of vertical tube 14 and between the hole wall of the sleeve joint hole 142 of the outer tube wall of vertical tube of front fork 12 and vertical tube 14, is worn and torn in order to avoid producing between vertical tube of front fork 12 and the vertical tube 14.The top of lining 16 has a retaining edge 162, is located at the end face of the garter spring 141 of vertical tube 14 in order to retaining, lets lining 16 can not come off from the sleeve joint hole 142 of vertical tube 14, and in addition, lining 16 has a profile groove 164, makes lining 16 can receive the external force effect and produces radial deformation.
And when rotating adjustment sleeve 24; Can change the screwed distance of 146 of adjustment sleeve 24 and vertical tube 14 installation portions; That is change between adjustment sleeve 24 and the axostylus axostyle 25 annexation; And then impel drive shaft rod 25 to produce longitudinal travel, and can adjust the elasticity of handle 22 when operation thus, when axostylus axostyle 25 moves, can establish and can not produce in addition and separate through the lock of latch fitting 26 with adjustment sleeve 24.
Restraint the root edge that part 50 is sheathed on vertical tube of front fork 12 and is positioned at vertical tube 14 down, the apical margin of following bundle part 50 has a limit turn trough 52, like Fig. 2 and shown in Figure 3, uses rotating limit block 148 for vertical tube 14 to be embedded and limits the rotational angle of vertical tube 14.What this needed supplemental instruction be; Limit turn trough 52 not necessarily will be formed at down the apical margin of bundle part 50; Also can be arranged on the root edge of bundle part 30; 148 of the rotating limit blocks of this moment are that the apical margin from the garter spring 141 of vertical tube 14 makes progress projection and goes out, and in other words, turn trough 52 can reach due effect as long as one of them of upper and lower bundle spare 30,50 has limit.
Can know via said structure; The unitized construction 10 of the utility model is utilized the design of upper and lower bundle spare 30,50, the installation of the packing assembly 40 of arranging in pairs or groups again; Can increase the structural stability between vertical tube of front fork 12 and the vertical tube 14 really; And following bundle part 50 can be fixed on the position of vertical tube of front fork 12 according to the different size adjustment of vertical tube 14, to increase convenience in the use.
On the other hand; The handle of quick detach assembly can have different forms; As shown in Figure 5; The vertical tube of front fork 61 that is provided for the utility model second preferred embodiment and the unitized construction 60 of vertical tube 62, its keystone configuration and above-mentioned first embodiment are roughly the same, precisely because difference is that the handle 64 of quick detach assembly 63 has only the top of single ear 642 and pivot to form and articulates; So except reaching tightening the effect originally, the problem that can avoid two ears 221 of the handle 22 of above-mentioned first embodiment when operation, to block simultaneously again.
Please consult Fig. 6 and Fig. 7 again, for the utility model the 3rd than the vertical tube of front fork 71 that embodiment provided and the unitized construction 70 of vertical tube 72, its keystone configuration and second embodiment are roughly the same, precisely because difference is the structure of vertical tube of front fork 71 and packing assembly 80.In the present embodiment, vertical tube of front fork 71 is arranged with a vehicle frame pipe 90, and the top of vertical tube of front fork 71 has an internal thread part 712, and the bottom of vertical tube of front fork 71 has one first inclined-plane 713.Packing assembly 80 has a loam cake 82, a bolt 84; An and clamp holder 86; Wherein, Loam cake 82 has an external thread part 822, makes loam cake 82 to be located at the internal thread part 712 of vertical tube of front fork 71 and to be fixed in the top of vertical tube of front fork 71 by external thread part 822 spiral shells itself, to reach the effect of bundle part 73 in the packing; But bolt 84 original places are arranged in the vertical tube of front fork 71 rotationally; Clamp holder 86 spiral shells are located at the terminal of bolt 84 and are had one second inclined-plane 862, and second inclined-plane 862 of clamp holder 86 amplexiforms with first inclined-plane 713 of vertical tube of front fork 71 each other.Thus; When rotating bolt 84; Clamp holder 86 will be through cooperating and vertical tube of front fork 71 generation oblique courses relatively between first inclined-plane 713 of second inclined-plane 862 and vertical tube of front fork 71 of itself; Make clamp holder 86 be able to the inner tubal wall that a packing face 864 is packed in vehicle frame pipe 90, with fixing between the unitized construction 70 of accomplishing the utility model and the vehicle frame pipe 90.
The constituent components that the utility model is disclosed in the foregoing description is merely casehistory, is not the scope that is used for limiting the utility model, and the substituting or change of other equivalent elements also should be the claim scope that the utility model applies for and contain.
