Abstract

The utility model discloses a 180 DEG invisible hinge, comprising a hinge mounting (8), and a door leaf pivoted arm (2), wherein a door leaf (1) is provided with an anti-prizing edge (4), a door frame (1) is provided with a pivoted arm connection aperture (3) and an outer step corresponding to the anti-prizing edge (4), the hinge mounting (8) is provided with a hinge shaft (6), a door frame pivoted arm (7) is sleeved onto the hinge shaft (6), the door leaf pivoted arm (2) is allowed to pass through the pivoted arm connection aperture (3) to be fixedly connected with the door frame pivoted arm (7), the included angle beta 1 between a bended edge (10) of the door frame pivoted arm (7) and a connection edge (11) is more than 100 DEG, the included angle beta 2 formed by two bended edges of the bended edge (10) is less than 90 DEG, the distance h1 between the hinge shaft (6) and the outer side surface of a door frame (9) is 18.5 mm, and the distance h2 between the hinge shaft (6) and the outer surface of the door frame (9) is 5.5 mm. The 180 DEG invisible hinge has the advantages of simple and reasonable structure, stable and reliable working, convenient installation, small volume and low cost, etc.

Description

180 degree blind hinges

Technical field

The utility model relates to the blind hinge that uses on a kind of security door, particularly a kind of blind hinge that can make the door leaf opening angle greater than 150 degree.

Background technology

At present, security door, steel doors etc. are gone up employed blind hinge, its door leaf opening angle does not generally wait between 90 to 110 degree, because security door, steel door generally is installed in wall face and outwards opens, when the rotational angle of blind hinge is above greater than 150 degree, door leaf just can be pressed close to metope and be fixed by door-inhale, when the rotational angle of blind hinge is above less than 150 degree, can not press close to metope after door leaf is opened is fixed on the door-inhale, and cause door leaf to block passage or corridor, bring inconvenience for user's life and work, particularly the influence that causes of corridor formula office space is bigger.In order not influence the current of passage or corridor, people are developing the blind hinge that can open greater than more than 150 degree on the basis of existing blind hinge, but existing blind hinge in use has the following disadvantages: the one, rotate comparatively smoothly 180 degree blind hinge complex structures, volume is big, cost is high, be unfavorable for promoting the use of, generally be used for high-grade security door, common security door does not generally use; The 2nd, when opening, the simple relatively 180 degree blind hinges of structure can run into the chimb door pocket, can only use the jib door cover, cause the chimb door pocket not use, the decoration effect is undesirable.For this reason, many manufacturers and knowledgeable people develop and manufacture experimently, but do not have rational product to emerge so far as yet.

Summary of the invention

In order to overcome the problems referred to above that existing 180 degree blind hinges exist, the purpose of this utility model provide a kind of simple in structure, working stability is reliable, easy for installation, volume is little, cost is low 180 degree blind hinges.

The technical scheme that its technical problem that solves the utility model adopts, it comprises the hinge mount that is fixed on the doorframe, is fixed on the door leaf pivoted arm on the door leaf, set up defences on the door leaf and prize the limit, have on the doorframe pivoted arm connecting hole and with the corresponding outer step in pick-proof limit, described hinge mount is provided with hinge, the doorframe pivoted arm is set on the hinge rotationally, and the door leaf pivoted arm is fixedlyed connected with the doorframe pivoted arm by screw after passing the pivoted arm connecting hole.

Described doorframe pivoted arm is made up of flanging and fillet, and the angle β 1 of flanging and fillet is greater than 100 degree, and the angle β 2 of flanging is less than 90 degree.

Described hinge is 18.5 millimeters apart from the distance h 1 of doorframe lateral surface, and hinge is 5.5 millimeters apart from the distance h 2 of doorframe external surface.

Described door leaf is apart from 3≤10 millimeters of the distance h of doorframe external surface.

After adopting said structure, the utility model has following advantage and effect: the one, owing to have only doorframe pivoted arm and pin joint of hinge between door leaf and the doorframe, open or close light flexibly.The 2nd, because the angle β 1 of flanging and fillet spends greater than 100, the angle β 2 of flanging spends thereby make the door leaf opening angle can reach 160 less than 90 degree.The 3rd, simple in structure, production and processing is convenient, and volume is little, and is in light weight, and cost is low, and is applied widely.

Wherein: 1 door leaf, 2 door leaf pivoted arms, 3 pivoted arm connecting holes, 4 pick-proof limits, 5 screws, 6 hinges, 7 doorframe pivoted arms, 8 hinge mounts, 10 flangings, 11 fillets.

The specific embodiment

Illustrated in figures 1 and 2, specific embodiments for the utility model 180 degree blind hinges, it comprises the hinge mount 8 that is fixed on the doorframe 9, is fixed on the door leaf pivoted arm 2 on the door leaf, set up defences on the door leaf 1 and prize limit 4, have on the doorframe 1 pivoted arm connecting hole 3 and with pick-proof limit 4 corresponding outer steps, described hinge mount 8 is provided with hinge 6, doorframe pivoted arm 7 is set on the hinge 6 rotationally, door leaf pivoted arm 2 passes pivoted arm connecting hole 3 backs fixedlys connected with doorframe pivoted arm 7 by screw 5, can be by the fit adjustment crack between a door and its frame gap of door leaf pivoted arm 2 with doorframe pivoted arm 7.

Described doorframe pivoted arm 7 is made up of flanging 10 and fillet 11, and the angle β 1 of flanging 10 fillets 11 is greater than 100 degree, and best choosing value is 102 degree, and the angle β 2 of flanging 10 is less than 90 degree, and best choosing value is 81 degree.Described hinge 6 is 18.5 millimeters apart from the distance h 1 of doorframe 9 lateral surfaces, and hinge 6 is 5.5 millimeters apart from the distance h 2 of doorframe 9 external surfaces, and described door leaf 1 is apart from 3≤10 millimeters of the distance h of doorframe 9 external surfaces.In the present embodiment, the angle β 1 of flanging 10 fillets 11 is 102 degree, and the angle β 2 of flanging 10 is 81 degree, and hinge 6 is set on the permanent position of doorframe 9, can make door leaf 1 open 160 degree.
