The utility model has the advantages that little structural design is reasonable in the rotary resistance.
Description
Technical field
This utility model relates to body hinge, specifically refers to high abrasion body hinge。
Background technology
Traditional body hinge includes: hinge axis, fixing seat of hinge, fixing bolt, articulate seat。Fixing seat of hinge and vehicle body are fixing to be connected, and articulate seat is connected with car door, passes through body hinge, it is achieved hinged in vehicle body of door relative。Owing to body hinge is common components, hinge bears the vertical force of car door for a long time, it is easy to make hinge axis abrasion bending。
For this, a kind of body hinge of the applicant's earlier application, as Chinese patent discloses shown in CN204252703U, it is additionally provided with axle sleeve between sliding seat and hinge axis, solves the technical problem of hinge axis abrasion bending and firm and durable more well。
But the body hinge shown in this patent in use also there is a problem that axle sleeve is owing to being limited to machining accuracy, after axle sleeve is assemblied in sliding seat and hinge axis, drastically increasing the rotary resistance of sliding seat, cause that car door opens and closes resistance big, user feedback is not good。
Summary of the invention
The purpose of this utility model is the shortcoming and defect in order to overcome prior art to exist, and provides the high abrasion body hinge of the little reasonable in design of a kind of rotary resistance。
For achieving the above object, the technical solution of the utility model is to include fixing seat, sliding seat and hinge axis, described hinge axis includes axis part, middle axis part, lower axis part, described fixed seating is located at described middle axis part, described sliding seat has two and is respectively provided on described upper axis part and lower axis part, it is additionally provided with axle sleeve between described sliding seat and hinge axis, in described upper axis part, between middle axis part and middle axis part, it is equipped with positive stop lug boss between lower axis part, it is additionally provided with back-up ring at the described upper and lower two ends of hinge axis, described axle sleeve is provided with the embedding hole of multiple ball pivot relative to circumference uniform distribution on the inner face of sliding seat side, in the embedding hole of this ball pivot, ball pivot is connected with rotation steel ball, the outer face of this rotation steel ball coordinates with the inner face of sliding seat slip apical grafting mutually。
The fixing seat being described is set further and includes vehicle body installation portion and fixing connecting portion, described fixing connecting portion is provided with the through hole of accommodating described middle axis part, described fixing seat upper end is additionally provided with tapped through hole, bolt is through described tapped through hole and the locking of described middle axis part, and the position of the corresponding described bolt in described middle axis part is provided with anti-skidding annular knurl。
The utility model has the advantages that by arranging rotation steel ball, it is possible to greatly reducing the rotary resistance between axle sleeve and sliding seat inner face, thus reduce car door rotary resistance, reasonable in design is reliable。
Below in conjunction with specification drawings and specific embodiments, this utility model is described further。
Accompanying drawing explanation
Fig. 1 is the sectional view of this utility model detailed description of the invention；
Fig. 2 is the lower view of this utility model detailed description of the invention。
Detailed description of the invention
By the examples below this utility model is specifically described, is served only for this utility model is further described, it is impossible to be interpreted as the restriction to this utility model protection domain。
Detailed description of the invention of the present utility model as shown in Figure 1-2, including fixing seat 1, sliding seat 2 and hinge axis 3, described hinge axis 3 includes axis part 31, middle axis part 32, lower axis part 33, described fixing seat 1 is set in described middle axis part 32, described sliding seat 2 has two and is respectively provided at described upper axis part 31 and lower axis part 33, it is additionally provided with axle sleeve 4 between described sliding seat 2 and hinge axis 3, in described upper axis part 31, between middle axis part 32 and middle axis part 32, it is equipped with positive stop lug boss 34 between lower axis part 33, it is additionally provided with back-up ring 5 at described hinge axis about 3 two ends, described axle sleeve 4 is provided with the embedding hole 41 of multiple ball pivot relative to circumference uniform distribution on the inner face of sliding seat 2 side, in the embedding hole of this ball pivot, ball pivot is connected with rotation steel ball 42, the outer face of this rotation steel ball 42 coordinates with the inner face slip apical grafting mutually of sliding seat 2。
Additionally, the fixing seat 1 of the present embodiment includes vehicle body installation portion 11 and fixing connecting portion 12, fixing connecting portion 12 is provided with the through hole of accommodating middle axis part 32, and fixing seat 1 upper end is additionally provided with tapped through hole 13, is locked through tapped through hole and middle axis part 32 by bolt 6。By adopting above-described embodiment, it is possible to make fixing seat 1 effectively lock and easy for installation with hinge axis 3。
Additionally, the position of the middle axis part correspondence bolt on hinge axis is provided with anti-skidding annular knurl 35。By adopting above-described embodiment, effectively can must play the locking to hinge axis 3, it is to avoid fixing seat and sliding seat abrasion when relatively rotating, to hinge axis。
