Abstract
The utility model discloses a 180-degree blind hinge which comprises a hinge seat (9), an adjustable connecting sheet (2), a door frame hinge arm (8) and a door leaf hinge arm (4); a door frame (10) is provided with a hinge arm connecting hole (11); the door frame hinge arm (8) is arranged on the hinge seat (9); the door leaf hinge arm (4) is fixed on the adjustable connecting sheet (2); the part of the door frame hinge arm (8) stretching out of the hinge arm connecting hole (11) adopts a circular arc sheet-shaped structure, and circular arc groove tracks (5) are respectively arranged on the upper end surface and the lower end surface of the stretching-out part of the door frame hinge arm (8); the door leaf hinge arm (4) is movably sheathed on the door frame hinge arm (8); and roll ball assemblies (7) matched with the circular arc groove tracks (5) on the door frame hinge arm (8) in a sliding way are respectively arranged on the upper end surface and the lower end surface of the door leaf hinge arm (4). By adopting the above structure, the 180-degree blind hinge overcomes the defect that the blind hinge cannot be opened at 180 degrees and has the advantages of being simple and reasonable in structure, stable and reliable in work, convenient to install, small in volume, low in cost and the like.
Description
Technical field
The utility model relates to a kind of blind hinge, particularly a kind of blind hinge that can make the door leaf opening angle greater than 150 degree.
Background technology
At present, security door, labeled door, employed blind hinge on the steel door, its door leaf opening angle does not generally wait between 90 to 110 degree, because security door, labeled 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 can't fix, and cause door leaf to block passage or corridor, bring inconvenience for user's life and work, what particularly caused formula office space in corridor has the greatest impact.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 in the trial-production installation process, have the following disadvantages: the one, blind hinge can not rotate synchronously up and down, causes closing or to open door leaf smoothly; The 2nd, the rotational structure complexity, volume is big, cost is high, is unfavorable for promoting the use of; The 3rd, can run into the chimb door pocket when opening, 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 seat that is fixed on the doorframe, is fixed on adjustable brace, doorframe pivoted arm and door leaf pivoted arm on the door leaf, have the pivoted arm connecting hole on the doorframe, the doorframe pivoted arm is arranged on the hinge seat by hinge rotationally, the door leaf pivoted arm by screw on adjustable brace, described doorframe pivoted arm stretches out the pivoted arm connecting hole, doorframe pivoted arm extension is the circular arc sheet structure, and its upper and lower end face is respectively equipped with the arc groove track; Described door leaf pivoted arm is movably set on the doorframe pivoted arm, and door leaf pivoted arm upper and lower end face is respectively equipped with the ball assembly, and the ball assembly cooperates with arc groove slide on the doorframe pivoted arm.
For the door leaf pivoted arm is worked according to certain rules, the upper and lower end face of described doorframe pivoted arm circular arc sheet structure slopes inwardly.
After adopting said structure, the utility model has following advantage and effect: the one, because the door leaf pivoted arm is set on the doorframe pivoted arm by the ball assembly, open or close light flexibly.The 2nd, because the upper and lower end face of doorframe pivoted arm circular arc sheet structure slopes inwardly, make the required slip resistance of door leaf pivoted arm greater than the hinge rotary resistance, therefore door leaf rotates around hinge earlier when opening, slide along the doorframe pivoted arm again, when the opposite direction motion is promptly closed, make the required slip resistance of door leaf pivoted arm less than rotary resistance, door leaf slides along the doorframe pivoted arm earlier, rotate around hinge again, solved the nonsynchronous problem of hinge up and down.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.

The specific embodiment
Fig. 1, Fig. 2 and shown in Figure 3, specific embodiments for the utility model 180 degree blind hinges, it comprises the hinge seat 9 that is fixed on the doorframe 10, is fixed on adjustable brace 2, doorframe pivoted arm 8 and door leaf pivoted arm 4 on the door leaf 1, have pivoted arm connecting hole 11 on the doorframe 10, doorframe pivoted arm 8 is arranged on the hinge seat 9 rotationally by hinge 6, door leaf pivoted arm 4 is fixed on the adjustable brace 2 by screw 3, described doorframe pivoted arm 8 stretches out pivoted arm connecting hole 11, doorframe pivoted arm 8 extensions are the circular arc sheet structure, and its upper and lower end face is respectively equipped with arc groove track 5; Described door leaf pivoted arm 4 is movably set on the doorframe pivoted arm 8, and door leaf pivoted arm 4 upper and lower end faces are respectively equipped with ball assembly 7, and the arc groove track 5 on ball assembly 7 and the doorframe pivoted arm 8 is slidingly matched.The upper and lower end face of described doorframe pivoted arm 8 circular arc sheet structures slopes inwardly.
The utility model work is as follows: when needs are opened door leaf 1, because the upper and lower end face of doorframe pivoted arm 8 circular arc sheet structures slopes inwardly, the required slip resistance of door leaf pivoted arm 4 is greater than hinge 6 rotary resistances, door leaf 1 rotates around hinge 6 with doorframe pivoted arm 8, run into the side of pivoted arm connecting hole 11 when doorframe pivoted arm 8 after, as shown in Figure 2, doorframe pivoted arm 8 no longer rotates around hinge 6; When continuing to open, door leaf 1 slides until opening, as shown in Figure 3 with the arc groove track 5 of door leaf pivoted arm 4 on the effect lower edge of ball assembly 7 doorframe pivoted arm 8.When closing door leaf 1, because the upper and lower end face of doorframe pivoted arm 8 circular arc sheet structures slopes inwardly, the required slip resistance of door leaf pivoted arm 4 is less than hinge 6 rotary resistances, door leaf 1 slides with the arc groove track 5 of door leaf pivoted arm 4 on the effect lower edge of ball assembly 7 doorframe pivoted arm 8 earlier, rotate around hinge 6 again after putting in place, close the door thereby finish.
