Abstract

The utility model discloses a hidden hinge, which belongs to a hinge or pivot type device operated and controlled by a spring. The device enables a fan to move to an opening or closing position. The hidden hinge adopts two groups of groove-shaped and pin shaft hinged right-angle bending rotating arms and arc bending rotating arms, wherein two right-angle bending rotating arms are hinged by pin shafts, and one group of right-angle bending rotating arms and the other group of arc bending rotating arms are connected onto a base, so the base has a 90-degree included angle in both the opening state or the closing state. One base (16) is connected with a concave spring pin shaft pulling hook support frame (14) which is connected with a U-shaped spring pin shaft pulling hook (13), and a tension spring (11) is respectively connected with the U-shaped spring pin shaft pulling hook (13) and a pin shaft (9). The hidden hinge is used for convex door installation, can be completely hidden, can realize 180-degree opening and closing and is flexible and powerful.

Description

The concealed type loose-leaf

Technical field

The utility model belongs to by spring-operated hinge or pivot shape device, and this device can make different fan move on to and open or fastening position.

Background technology

At present furniture door has the tendency of using protruding door from attractive in appearance, and protruding door is used common loose-leaf, can make 180 ° of keyings of door leaf, but pivot exposes, and influences outward appearance.For hidden pivot, notification number CN2118787U discloses a kind of blind hinge, and this hinge is to increase folding between Fixed hinge and loose-leaf, though the hidden pivot of this loose-leaf energy, door leaf can only be opened 90 °, uses extremely inconvenient.

Summary of the invention

Problem to be solved in the utility model provides a kind of concealed type, function is various, install easier, the concealed type loose-leaf that in 180 ° of scopes, can open and close arbitrarily.

For solving the problems of the technologies described above, solution of the present utility model is a kind of concealed type loose-leaf, two quarter bend pivoted arms are hinged with bearing pin, it is hinged that wherein the minor face of quarter bend pivoted arm and arc curve arm one end usefulness bearing pin, the long limit of quarter bend pivoted arm is prominent along last with the hinged base of bearing pin, arc curves the arm other end dashing forward along last with the hinged base of bearing pin, it is hinged with bearing pin that the minor face of quarter bend pivoted arm and arc curve arm one end, on the prominent edge of base, arc curves the arm other end and uses rivet on the prominent edge of base with rivet on the long limit of quarter bend pivoted arm; At a base matrix axis pin of the spring of rivet drag hook support, matrix axis pin of the spring drag hook frame bottom is concordant with the base lower edge, matrix axis pin of the spring drag hook support connects a U type axis pin of the spring drag hook, and extension spring connects U type axis pin of the spring drag hook and bearing pin respectively.

Four jiaos of punching out of above-mentioned base have 2 circular screwholes and the long screw of arc that is that diagonal arranges, the position of circular screwhole and the long screw of arc can exchange.

The axle center of above-mentioned U-shaped axis pin of the spring drag hook and the axle center of rivet are overlapping.

The utility model is owing to adopted two groups of flute profile pivoted arms that are hinged and corresponding base, the corresponding connection matrix of one of them base axis pin of the spring drag hook support and a U-shaped axis pin of the spring drag hook, and there is spring to assist, so be used for protruding door loose-leaf, not only can be all hidden, and also 180 ° open and close protruding door, strong flexibly, matrix axis pin of the spring drag hook frame bottom is concordant with the base lower edge, need not punching on door and frame hinge is installed, install easier, save time.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but does not constitute restriction of the present utility model.

See Fig. 1, two quarter bend pivoted

arms

8 and 5 usefulness bearing pins 7 are hinged, it is hinged that wherein the minor face of quarter bend pivoted arm 8 and arc curve arm 4 one ends usefulness bearing pin 6, the long limit of quarter bend pivoted arm 5 is prominent along last with bearing pin 3 hinged bases 1, arc curves arm 4 other ends dashing forward along last with bearing pin 2 hinged bases 1, it is hinged with bearing pin 9 that the minor face of quarter bend pivoted arm 5 and arc curve arm 10 1 ends, the long limit of quarter bend pivoted arm 8 is riveted on the prominent along last of base 16 with rivet 12, and arc curves arm 10 other ends and is riveted on the prominent along last of base 16 with rivet 15; On base 16, rivet a matrix axis pin of the spring drag hook support 14 with

rivet

12,15, matrix axis pin of the spring drag hook support 14 bottoms are concordant with base 16 lower edges, matrix axis pin of the spring drag hook support 14 connects a U-shaped axis pin of the spring drag hook 13, and extension spring 11 connects U-shaped axis pin of the spring drag hook 13 and bearing pin 9 respectively.

The closure state of the utility model concealed type loose-leaf is seen Fig. 2.

Fig. 3 is seen in the utility model part.This figure is symmetry substantially.Rivet 12 is riveted prominent edge, the long limit of quarter bend pivoted arm, the matrix axis pin of the spring drag hook support 14 of base 16 successively, rivet 15 curves arm 10 other ends, 14 riveted joints of matrix axis pin of the spring drag hook support with prominent edge, the arc of base 16 successively, there is a cavity at matrix axis pin of the spring drag hook support 14 middle parts, place one can be movable U-shaped axis pin of the spring drag hook 13, extension spring 11 connects U-shaped axis pin of the spring drag hook 13 and bearing pin 9 respectively, and most preferred embodiment is that the axle center of the axle center of U-shaped axis pin of the spring drag hook 13 and rivet 15 is overlapping.16 4 jiaos of punching out of base have 2 circular screwholes 17 and the long screw 18 of arc that is that diagonal arranges, the position of circular screwhole and the long screw of arc can exchange.Adopt the long screw of arc act as mounting screw the time can finely tune the assurance installation quality.

Quarter bend pivoted arm of the present utility model and arc curve arm and are flute profile, all there is pin-and-hole the end of two kinds of pivoted arms, base is the concave and convex plane shape with the metal sheet punching out, with the pivoted arm hinged place the prominent edge that upwarps is arranged, and matrix axis pin of the spring drag hook support 14 is concordant with the bottom of base 16.
