The specific embodiment
Below by particular specific embodiment embodiment of the present invention is described, be familiar with this technological personage and can understand other advantages of the present invention and effect easily by the content that this specification sheets disclosed.
Notice; The appended graphic structure that illustrates of this specification sheets, ratio, size etc.; All only in order to cooperate the content that specification sheets disclosed, understanding and reading for being familiar with this technological personage, is not in order to limit the enforceable qualifications of the present invention; Event is the technical essential meaning of tool not; The adjustment of the modification of any structure, the change of proportionate relationship or size is not influencing under effect that the present invention can produce and the purpose that can reach, all should still drop in the scope that disclosed technology contents can contain.Simultaneously; Quoted in this specification sheets as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc.; Also be merely be convenient to narrate clear, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment; Under no essence change technology contents, when also being regarded as the enforceable category of the present invention.
As shown in Figure 1, the present invention provides a kind of dowel bar axial limiting structure of seat angle adjustor, comprises dowel bar 1 and back-up ring 2; Said dowel bar 1 is a hollow stem, sees Fig. 4 to Fig. 6, and said back-up ring 2 comprises an annulus portion 21 and an endoporus 22; Said annulus portion 21 has a stressed end face 211 and a non-stress end face 212; Between said annulus portion 21 and endoporus 22, also be provided with a plurality of elasticity gear pieces 23, the fixed end 231 of said elasticity gear piece links to each other with annulus portion 21 one at stressed end face 211 places, and the free end 232 of elasticity gear piece tilts to non-stress end face 212 directions; See Fig. 2; The diameter D1 of said back-up ring endoporus 22 is less than the maximum outside diameter D2 of said dowel bar 1, and when back-up ring 2 is installed in 1 last time of dowel bar, the free end 232 of said elasticity gear piece is pressed on the surface of dowel bar 1.Preferably, said annulus portion 21 outer rims are provided with flange 24, and said flange 24 is vertical with stressed end face 211, and flange 24 guarantees the rigidity of stressed end face 211, even stressed end face 211 (or annulus portion 21) can not deform in back-up ring 2 receives the process of axial force.
In the dowel bar axial limiting structure of the seat angle adjustor that the present invention relates to; Captiveing joint of back-up ring 2 and dowel bar 1 realized on the surface that free end 232 through the elasticity gear piece is pressed on dowel bar 1; Be back-up ring 2 with dowel bar 1 for interference is connected, this structure is convenient to inspection, adjustment and the replacing of back-up ring 2.
Further, said elasticity gear piece 23 is 34 ° with the initial angle of stressed end face 211, sees Fig. 6; When back-up ring 2 is installed in 1 last time of dowel bar, certain elastic deformation can take place in elasticity gear piece 23 in installation process, so after installing, the angle of elasticity gear piece 23 and stressed end face 211 becomes 40 °, sees Fig. 3.
Further, said dowel bar 1 cross-sectional plane be shaped as star with a plurality of protrusions 11, said protrusion 11 contacts with the free end 232 of elasticity gear piece.In the present embodiment, said dowel bar is 5 star dowel bars, and promptly said protrusion 11 is 5, sees Fig. 7; Perhaps, said dowel bar is 6 star dowel bars, and promptly said protrusion 11 is 6, sees Fig. 8.
During installation, see Fig. 9, should be pressed into the back-up ring 2 of dowel bar 1 left end from left to right on the dowel bar 1 this moment, and in the installation process, certain distortion can take place elasticity gear piece 23, and the free end 232 of elasticity gear piece is pressed on the surface of dowel bar 1.Do the time spent (being that axial force F acts on the stressed end face 211) when what back-up ring 2 received axial force F; Back-up ring 2 can produce the trend to left movement; This moment, the free end 232 of elasticity gear piece had the trend towards dowel bar 1 motion; Hollow dowel bar 1 is easy to generate distortion after receiving the application force that elasticity gear piece 23 applies, so there is a very big static friction force between the contact surface of the free end 232 of elasticity gear piece and dowel bar 1; This static friction force guarantees that effectively back-up ring 2 can not produce longitudinal travel under the effect of axial force F, has promptly guaranteed the axial limiting function of back-up ring 2.
In sum; In the dowel bar axial limiting structure of the seat angle adjustor that the present invention relates to; Be connected with the interference of dowel bar through back-up ring and tightly be fixed on back-up ring on the dowel bar; The free end that is elasticity gear piece in the back-up ring tightly is pressed on the surface of dowel bar, forms back-up ring and is connected with the removable of dowel bar, is convenient to detection, adjustment and the replacing of back-up ring.Simultaneously, when receiving axial force on the stressed end face of back-up ring, produce certain friction force between the free end of elasticity gear piece and the contact surface of dowel bar, effectively anti-Sealing shield ring produces longitudinal travel, and then guarantees the axial limiting effect of back-up ring.So the present invention has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.
The foregoing description is illustrative principle of the present invention and effect thereof only, but not is used to limit the present invention.Any be familiar with this technological personage all can be under spirit of the present invention and category, the foregoing description is modified or is changed.Therefore, have common knowledge the knowledgeable in the affiliated such as technical field, must contain by claim of the present invention not breaking away from all equivalence modifications of being accomplished under disclosed spirit and the technological thought or changing.
