Abstract

The utility model relates to an exterior door hinge structure capable of limiting an opening angle of a door body. The exterior door hinge structure capable of limiting the opening angle of the door body comprises an upper hinge with an upper shaft hole and a lower hinge with a lower shaft hole, the upper hinge is fixed on the door body, the lower hinge is fixed on a door frame, and a hinge shaft is arranged in the upper shaft hole and the lower shaft hole in an inserting mode. The exterior door hinge structure capable of limiting the opening angle of the door body is characterized in that a stop block is sleeved on the hinge shaft, the stop block is arranged between the upper hinge and the lower hinge and fixed relative to the door frame, a stop plane which is arranged in an inclined mode is arranged on the inner side of the stop block, and the stop plane sideways protrudes out of the outer circumference of the upper hinge. When the door body is in a closed state, an obtuse angle is formed between the stop plane and the front end surface of the door body. When the door body is in a state of the largest opening angle, the front end surface of the door body is contacted with the stop plane. The door body is stopped by the stop plane, so that collision between the door body and the door frame or a wall body because of excessive opening of the door body to affect the surface quality of the door body is avoided.

Description

The outer door hinge structure that energy opposite house body opening angle limits

Technical field

The utility model relates to a kind of outer door hinge, relates in particular to the outer door hinge structure that a kind of energy opposite house body opening angle limits, and this outer door hinge is suitable on ATM safety cabinet, strongbox (cabinet), file cabinet, safe cabinet, the cashbox door.

Background technology

Traditional be used on the door body door hinge its generally include blade and the lower blade with shaft hole that structure is mutually symmetrical, wherein blade is installed on the body, lower blade is installed on the doorframe, and on blade and lower blade, respectively have a plurality of installing holes, so that install, one rotating shaft is passed in simultaneously the shaft hole on blade and the lower blade and both is linked together, and is positioned on blade and the lower blade in the riveted joint of the outer end of each shaft hole.

As the patent No. be Chinese utility model patent " a kind of structure of automatic returning door hinge ", the patent No. of ZL96211963.6 (notification number is CN2299922Y) be Chinese utility model patent " Spring door hinge ", the patent No. of ZL02205657.2 (notification number is CN2526432Y) be ZL03268199.2 (notification number is CN2632252Y) Chinese utility model patent " a kind of Foldalbe door hinge " they all disclosed similar hinge arrangement.

As shown in Figure 6, can relatively rotate the angle greater than 180 degree between blade in the above-mentioned various door hinge and the lower blade, if adopt the mentioned hinge structure door body to be installed on the doorframe of cabinet, door is known from experience relative doorframe wide-angle deflection like that, the lateral wall of external door and safe body is bumped, or bump with the wall of contiguous cabinet, cause affecting the surface quality of a body.

Summary of the invention

Technical problem to be solved in the utility model be provide for above-mentioned prior art present situation a kind of simple in structure and can opposite house the outer door hinge structure that limits of body opening angle, use the anglec of rotation of door body of this hinge controlled, avoid in opening process, bumping between the Men Tiyu doorframe and make the surface quality of a body impaired.

The utility model solves the problems of the technologies described above the technical scheme that adopts: the outer door hinge structure that a kind of energy opposite house body opening angle limits, comprise the upper hinge with upper shaft hole, lower hinge with lower shaft hole, upper hinge one side is fixed on the body, lower hinge then is fixed on the doorframe, described upper shaft hole and lower shaft hole are each other over against being positioned on the same axis, there is hinge axis to be plugged in simultaneously in upper shaft hole and the lower shaft hole, it is characterized in that: also be arranged with stopper on the described hinge axis, described stopper is between upper hinge and lower hinge and relative with doorframe fixing, the inboard of stopper has the stop flat that is obliquely installed, this stop flat side direction is protruded the upper hinge outer peripheral face, under the state that the door body is closed, angulation is the angle at obtuse angle between the front end face of described stop flat and door body, under the maximum angle state that the door body is opened, the front end face of described door body contacts with described stop flat.

The inner face of above-mentioned stopper is the spacing plane that forms plane contact with the outer face of described doorframe.By the plane contact of stopper and doorframe outer face so that stopper not relatively doorframe rotate around hinge axis, stopper is at the position-limiting action of hinge axis and correlation plane like this, realizes the relative fixing of stopper and doorframe.Certainly stopper also can adopt mode and the doorframe of for example welding to fix.

Connect by interior transition cambered surface between the bottom on above-mentioned stop flat inner edge and spacing plane.Interior transition cambered surface plays the shutter surface and is not blocked the piece scuffing so that the door body can not collide with stopper in opening process.

Because the stopper outside exposes outside the doorframe side, and connects by outer transition cambered surface between the top on above-mentioned stop flat outside and spacing plane.Exposed face is that cambered surface can prevent that stopper from scratching the people, and good looking appearance.

Above-mentioned upper shaft hole is the blind hole of upper end closed, lower ending opening, and described lower shaft hole is axially extending bore, and the bottom thread in the lower shaft hole is connected with the holding screw sealing.

Be provided with steel ball between the bottom surface of above-mentioned holding screw and hinge axis.Steel ball is set can make a body unlatching lighter.

Compared with prior art, the utility model has the advantage of: the hinge axis between upper hinge and lower hinge is provided with and the relatively-stationary stopper of doorframe, the inboard of stopper has the stop flat that is obliquely installed, like this after the door body is opened certain angle, stop flat just can contact with the door body, the barrier door body is further opened, and avoids a body transition unlatching and doorframe or body of wall to bump and affects the surface quality of a body; In addition, the size of door body opening angle is the number of degrees of the angle that forms between the front end face of stop flat and door body, only needs just can realize by the number of degrees that change angle the control of opposite house body opening angle, and opening angle can be set according to actual conditions.
