Abstract
The utility model discloses an angle limiting structure for a hinge unit, which comprises a mandrel and a winding bracket. One end of the winding bracket is internally rolled to form a winding ring for the mandrel to insert and rotate; a window is arranged on the wall of the winding ring; a mounting hole is arranged on the mandrel, corresponding to the window; a limiting piece with the outer end extending into the window is fixed in the mounting hole; and the width of the window in the circumferential direction of the winding ring is bigger than the maximum width of the limiting piece of the window in the circumferential direction of the winding ring. The angle limiting structure is simple in structure and limits the rotation angle of the mandrel and the winding ring of the bracket through the collision of a spring catch and two circumferential ends of the window. Meanwhile, the spring catch has the function of axially fixing the mandrel and the winding bracket. The angle limiting structure is convenient to process and assemble, and an operator only needs to process a window on the winding ring and a mounting hole on the mandrel and then fixes the spring catch in the mounting hole after the winding ring and the mandrel are assembled.
Description
Technical field
The utility model relates to a kind of angle limit structure of hinge means.
Background technique
Hinge means is widely used on the electronic products such as computer, mobile phone, digital camera and vidicon 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 element 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 angle of swing with fixed support and runing rest fixed electronic products.
Summary of the invention
The utility model purpose provides a kind of angle limit 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 limit structure of hinge means, comprise mandrel and roll film support, the involute volume circle that is inserted and rotated 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 mounting hole, described mounting hole internal fixation has the outer end to stretch into the interior bounding means of fenestra, and described fenestra encloses circumferential width greater than the Extreme breadth of the bounding means in the fenestra in this direction in volume.
The further technological scheme of the utility model is: a kind of angle limit structure of hinge means, comprise mandrel and roll film support, the involute volume circle that is inserted and rotated 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 mounting hole, described mounting hole internal fixation has the outer end to stretch into the interior bounding means of fenestra, and described fenestra encloses circumferential width greater than the Extreme breadth of the bounding means in the fenestra in this direction in volume.
Described bounding means is the spring pin that the outer end is positioned at fenestra, and described spring pin tensioning is fixed in the mounting hole, and the axial width of described fenestra is corresponding with the diameter of spring pin.
The utility model advantage is:
1. the utility model is simple in structure, collides the rotation angle that limits mandrel and support volume circle by spring pin and the circumferential two ends of fenestra; Simultaneously spring pin 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 mounting hole respectively on volume circle and mandrel, after the assembling spring pin inserted also tensioning and be fixed in the mounting hole and get final product.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: to shown in Figure 5, a kind of angle limit 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 mounting hole 5, described mounting hole 5 internal fixation have the outer end to stretch into bounding means 6 in the fenestra 4, described fenestra 4 in the circumferential width of volume circle 3 greater than the Extreme breadth of the bounding means in the fenestra 46 in this direction, make when mandrel 1 rotates with respect to roll film support 2 that bounding means 6 can slide in the part of fenestra 4 between the circumferential two ends of fenestra 4.
Described bounding means 6 is positioned at the spring pin of fenestra 4 for the outer end, after spring pin inserts in the mounting hole 5 outwards the hole wall of tensioning and mounting hole 5 fix.The axial width of described fenestra 4 is corresponding with the diameter of spring pin, makes roll film support 2 and mandrel 1 axial restraint.Spring pin has played axial restraint and circumferentially spacing effect simultaneously.
The utility model is simple in structure, collides the rotation angle that limits mandrel and support volume circle by spring pin and the circumferential two ends of fenestra; Simultaneously spring pin 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 mounting hole respectively on volume circle and mandrel, after the assembling spring pin is fixed in the mounting hole to get final product.
