Background

The application of folding, flip and posture product such as supporting auxiliary stay device including panel computer, cell-phone and desktop on the existing market is more general, and its advantage embodies in the convenience of using and carrying, can also set up spacingly according to user's actual need's angle, although some pivot devices have damping rotation function and automatic pause and frustrate limit function, but, the pivot device of current folding, flip and posture product, at the in-process of concrete use, still the ubiquitous shortcoming as follows or not enough: when the damping is rotationally unfolded or rotationally folded, the hinge is too loose, the hand feeling of use is not ideal, the smoothness and the limit pause feeling of rotation are not obvious, the tightness of the structure between hinge accessories and the coordination can not be felt, especially when the damping is rotationally unfolded or rotationally folded, the pause feeling effect is not obvious, and the use effect of the limit angle set according to the actual needs of a user is not ideal. Therefore, with the continuous advancement of science and technology and the continuous update of products, the hinge devices of the existing folding, flip and bracket products still need to be further improved and innovated, so as to meet the actual needs of the market in the future.

Disclosure of Invention

The utility model aims to solve the technical problem that a spacing type pivot device of rotatory auto-lock of reinforcement formula damping is provided, both can the damping levogyration but also can the damping dextrorotation, can also realize unsmooth pause and frustrate auto-lock limit function to the angle that sets up according to user's actual need, and pause and feel obvious to improve the tightness and the complex harmony of structure, especially additional strengthening's fastness.

The technical problem of the utility model is realized according to following technical scheme: the utility model provides a construct spacing type pivot device of rotatory auto-lock of reinforcement formula damping, a serial communication port, including the axle core of side flat and the reinforcement piece, runing rest, spacing cam, damping play piece group, brake pad piece and the nut that is fixed in the tip that alternates in proper order, wherein, runing rest is provided with synchronous PIN riveting and encircles the axle core and be synchronous revolution with the homonymy of reinforcing the reinforcement piece, and synchronous PIN also calls synchronous rivet or synchronous PIN, links up the part promptly, runing rest is provided with spacing concave wheel to be provided with slope fan-shaped recess on the surface of this spacing concave wheel, corresponding be provided with slope fan-shaped boss on the surface of spacing cam, slope fan-shaped boss is unsmooth pause and frustrates the spacing cooperation of auto-lock with slope fan-shaped recess.

According to the utility model provides a spacing type pivot device of rotatory auto-lock of reinforcement formula damping, a serial communication port, set up wear-resisting gasket respectively around consolidating the reinforcement piece, and, wear-resisting gasket and brake pad set up the flat hole respectively with the axle core is and encircles spacing cooperation, prevents promptly that wear-resisting gasket and brake pad from encircleing the axle core rotatory, damping bullet group is the elasticity plastic disc of nest form, at concrete implementation in-process, including synthetic rubber and synthetic rubber etc. certainly, also includes other elastic plastic. In specific implementation, the reinforcing plate is arranged to increase the structural strength of the support, and the wear-resistant plate is arranged to increase the contact area between objects and the rough surface of the surface so as to increase the friction force and generate larger torsion under the condition that the pressure of the damping elastic plate group is not changed.

Realize the utility model discloses a spacing type pivot device of rotatory auto-lock of reinforcement formula damping has following advantage: realized the rotatory function of expanding or the rotatory function of folding up of damping levogyration or damping dextrorotation to and realize unsmooth pause and pause in to the angle that sets up according to user's actual need and frustrate self-locking limit function, have obvious pause and pause in and frustrate the sense, effectively improved the tightness and the complex harmony of structure, especially strengthened the intensity of support, the utility model discloses the novel structure, rational in infrastructure, it is easy to implement, and market potential is big, has strengthened the convenience, the practicality and the flexibility of foldable, flip formula and posture product.
