Abstract

The utility model discloses an angle-limiting structure for a hinge device, which comprises a core shaft and a sheet rolling bracket, wherein, one end of the sheet rolling bracket is rolled inwards to form a rolled ring which allows the core shaft to insert, a window hole is formed on the wall of the rolled ring, a mounting hole formed on the core shaft is positioned opposite to the window hole, a limit component, of which the outer end extends into the window hole, is fixed in the mounting hole, and the width in the circumferential direction of the window hole is larger than the maximum width in the same direction of the limit component. Besides a simple structure, the utility model has the following advantages: rotating angles of the core shaft and the rolled ring on the bracket are limited by the collision between a bolt and the two ends in the circumferential direction of the window hole, and meanwhile, the bolt also serves to fix in the axial direction the core shaft and the sheet rolling bracket; and as to the processing and assembly of the angle-limiting structure, all that is needed is to make a window hole and a mounting hole on the rolled ring and the core shaft respectively, and fix the bolt in the mounting hole after assembly.

Description

The angle limits structure of hinge means

Technical field

The utility model relates to a kind of angle limits structure of hinge means.

Background technology

Hinge means is widely used on the electronic products such as computer, mobile phone, digital camera and video camera, makes these product foldings along sliding.Hinge means generally comprises mandrel, with the fixing fixed support of mandrel, the runing rest that can rotate around mandrel, the elastic component that torsion is provided and with lock locking member on mandrel of fixed support, runing rest and elastic component.Generally, on hinge, also the angle limits structure to be set in order to limit respectively the two-part anglec of rotation with fixed support and runing rest fixed electronic products.

Summary of the invention

The utility model purpose provides a kind of angle limits structure of hinge means, and it is simple in structure, processing, easy to assembly.

The technical solution of the utility model is: a kind of angle limits structure of hinge means, comprise mandrel and roll film support, the involute volume circle that inserts for mandrel that forms of one end of described roll film support, have fenestra on the described volume circle wall, the position that described mandrel is corresponding with fenestra is provided with installing hole, be fixed with the outer end in the described installing hole and stretch into the interior locating part of fenestra, described fenestra encloses circumferential width greater than the Breadth Maximum of locating part in this direction in volume.

Described locating part is the screw that head is positioned at fenestra, and described installing hole is the screw corresponding with screw, and the axial width of described fenestra is corresponding with the diameter of screw head.

The utility model advantage is:

1. the utility model is simple in structure, collides the rotational angle that limits mandrel and support volume circle by screw and the circumferential two ends of fenestra; Simultaneously screw also plays the effect at axial restraint of mandrel and roll film support.

2. the utility model processing, easy to assembly only need be processed fenestra and installing hole respectively on volume circle and mandrel, after the assembling screw is got final product in installing hole.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment: to shown in Figure 5, a kind of angle limits structure of hinge means comprises mandrel 1 and roll film support 2 as Fig. 1, the involute volume circle 3 that inserts for mandrel 1 that forms of an end of described roll film support 2.When mandrel 1 rotated in volume circle 3, the two frictional interference made the volume circle produce torsion.Described volume encloses and has fenestra 4 on 3 walls, described mandrel 1 and fenestra 4 corresponding positions are provided with installing hole 5, be fixed with the outer end in the described installing hole 5 and stretch into locating part 6 in the fenestra 4, described fenestra 4 in the circumferential width of volume circle 3 greater than the Breadth Maximum of locating part 6 in this direction, make when mandrel 1 rotates with respect to roll film support 2 that locating part 6 can slide in the part of fenestra 4 between the circumferential two ends of fenestra 4.

Described locating part 6 is positioned at the screw of fenestra 4 for head, and described installing hole 5 is the screw corresponding with screw, and the axial width of described fenestra 4 is corresponding with the diameter of screw head, makes roll film support 2 and mandrel 1 axial restraint.Screw has played axial restraint and circumferentially spacing effect simultaneously.

Mandrel 1 one ends insert in the volume circle 3 can relative rotation in certain angle with roll film support 2, and the other end vertically is bent to form fixed part 7, is provided with above that installing hole is used as fixed support and other part is fixed.The part that mandrel 1 is positioned at volume circle 3 also is provided with ring-shaped groove for preserving lubrication oil.

The utility model is simple in structure, collides the rotational angle that limits mandrel and support volume circle by screw and the circumferential two ends of fenestra; Simultaneously screw also plays the effect at axial restraint of mandrel and roll film support; The utility model processing, easy to assembly only need be processed fenestra and installing hole respectively on volume circle and mandrel, after the assembling screw is got final product in installing hole.
