Abstract
The invention discloses a hinge structure of a steel security door. The hinge structure comprises a door frame, a door leaf and a hinge. The hinged part of the door leaf with the door frame is provided with an anti-prizing projection, a protruding step surface is formed, and the door frame correspondingly forms a recess step surface. The hinge is provided with a pivot and two hinge pieces, the hinge pieces are fixed with the door frame and the door leaf respectively, the combined parts of the surfaces of the door frame and the door leaf with the hinge are provided with an elongated through hole respectively, the hinge pieces penetrate the elongated through holes respectively and extend into the door frame and the door leaf. The hinge pieces are substantially planar and provided with screw holes, and fastening bolts penetrate the surfaces of the door frame and the door leaf respectively and are connected with the hinge pieces in a threaded manner. The hinge pieces are provided with screw holes, and the hinge pieces are used as bases of the bolts. Thus, gaskets in the prior art and welding are omitted, and material quality and thickness of the hinge pieces are generally excellent than other parts, so that the hinge pieces as the bases of the bolts can guarantee firmness of mounting better.
Description
Technical field
The invention belongs to safety door technical field, particularly a kind of hinge arrangement of steel door.
Background technology
Steel door is made up of doorframe and door leaf, and its top layer material is stainless steel, and doorframe is fixed on body of wall, and door leaf can rotate relative to doorframe, and both are connected by hinge.Hinge has a pivot and two panels hinge plate, and two panels hinge plate fixes with doorframe and door leaf respectively.In view of steel door requires higher in safety, fastness, its hinge arrangement also has special character.Specifically, door leaf has pick-proof projection with doorframe hinged place, and namely door leaf is not a plane herein, but has the step surface of an evagination; Correspondingly, doorframe, in order to be mated, forms the step surface of an inside indentation.Therefore, the plane hinge sheet that its hinge plate used neither be commonly used, but the hinge plate with trisquare shape folding face.Obviously, this hinge processing is more complicated, and cost is higher.
Meanwhile, in order to make door leaf and doorframe at closing time fit, hinge should not become the obstruction of both junctions.In the prior art, be at installation hinge plate place, scratch the surface steel sheet diging up a part of doorframe or door leaf, after hinge plate is loaded onto, just in time fill up this and scratch the part of digging, thus still form the plane of complete laminating.After adopting this way, in order to provide the screw installed to hinge, and in order to the requirement of strength of satisfied installation, also need the pad arranging a band screw in the inside of doorframe and door leaf, this pad is fixed on doorframe and door leaf inside with Type of Welding.Such scheme, each hinge just needs to increase two panels pad, because this increasing cost; And on doorframe and door leaf, carry out welding operation, the paint life-span can be affected, cause the decline of total quality.
Hinge of the prior art is mounted in outside doorframe and door leaf, namely the hinge plate exposed can be seen when the door is open, and hinge plate stretches in doorframe and door leaf by the present invention, user can't see hinge plate, and first this bring a kind of brand-new Consumer's Experience.Substantive distinguishing features of the present invention offers screw on hinge plate, used by the pedestal of hinge plate as bolt; So just eliminate pad of the prior art, also omit welding process, simultaneously the quality of materials of hinge plate, thickness are generally better than other parts of door, make with hinge plate the fastness that bolt pedestal more can guarantee to install.Two panels hinge plate is out-phase, means relative to pivot, and two panels hinge plate is not in same angle, but certain angle that staggers.Like this after stretching into doorframe and door leaf respectively, the phase difference between two panels hinge can be filled up in the gap between doorframe and door leaf, makes whole hinge arrangement more tightly meticulous.
Summary of the invention
The object of this invention is to provide a kind of hinge arrangement not needing the steel door of pad and welding operation.
For this reason, the technical solution used in the present invention is such: the hinge arrangement of steel door, comprises doorframe, door leaf and hinge, and door leaf has a pick-proof projection with doorframe hinged place, and form the step surface of an evagination, doorframe correspondingly forms a step surface inside contracted; Hinge has a pivot and two panels hinge plate, and two panels hinge plate fixes with doorframe and door leaf respectively; It is characterized in that: the surface of doorframe and door leaf respectively has a microscler through hole in the joint portion with hinge, and hinge plate is each passed through described microscler through hole, stretch into doorframe and door leaf inside; Described hinge plate main body is plane, is provided with screw; Fastening bolt is each passed through doorframe and door leaf surface, is threaded with hinge plate.
Further, two panels hinge plate is out of phase hubbed on pivot.
Accompanying drawing explanation
Be described in further detail below in conjunction with accompanying drawing and embodiments of the present invention.
Fig. 1 is prior art schematic diagram of the present invention.
Fig. 2 is structural representation of the present invention.
Fig. 3 is the partial enlarged drawing of Fig. 2.
Detailed description of the invention
See accompanying drawing.The prior art of the present embodiment as described in Figure 1, steel door is made up of doorframe 2 and door leaf 3, and doorframe 2 is fixed on body of wall, and door leaf 3 can rotate relative to doorframe, and both are connected by hinge 6.Hinge 6 has a pivot and two panels hinge plate 62, and two panels hinge plate 62 fixes with doorframe 2 and door leaf 3 respectively; Door leaf 3 has pick-proof projection 31 in the hinged place with doorframe 2, and namely door leaf 3 is not a plane herein, but has the step surface of an evagination; Correspondingly, doorframe 2, in order to be mated, forms the step surface of an inside indentation, and described hinge plate 12 has trisquare shape folding face.At installation hinge plate place, need to scratch the surface steel sheet diging up a part of doorframe 2 or door leaf 3, after hinge plate 12 is loaded onto, just in time fill up this and scratch the part of digging, thus still form the plane of complete laminating.The inside of doorframe and door leaf also arranges the pad 5 of a band screw, and this pad 5 is fixed on doorframe 2 and door leaf 3 inside with Type of Welding.
As described in Figure 2, the present embodiment comprises doorframe 2, door leaf 3 and hinge 1, and door leaf 3, having a pick-proof projection 31 with doorframe 2 hinged place, forms the step surface of an evagination, and doorframe 2 correspondingly forms a step surface inside contracted; Hinge 1 has pivot 11, first hinge plate 12 and second hinge plate 13; Described first hinge plate 12 fixes with doorframe 2, and doorframe 2 has the first microscler through hole 21 towards the one side of pivot 11 in the joint portion with hinge 1; Described first hinge plate 12, through the first described microscler through hole 21, stretches into doorframe 2 inner; The first described hinge plate 12 main body is plane, and end bends, near the surface of doorframe 2 towards doorframe 2 surface; The first described hinge plate 12 is provided with screw 121; Fastening bolt 4 passes the one side relative with door leaf 3 of doorframe 2, with being threaded of the first hinge plate 12.Described second hinge plate 12 fixes with door leaf 3, and door leaf 3 has the second microscler through hole 32 towards the one side of pivot 11 in the joint portion with hinge 1; Described second hinge plate 13, through the second described microscler through hole 32, stretches into door leaf 3 inner; The second described hinge plate 13 main body is plane, is provided with screw 131; Fastening bolt 4 passes the one side relative with doorframe 2 of door leaf 3, with being threaded of the second hinge plate 13.
The first hinge plate 12 in the present embodiment and the second hinge plate 13 are out of phase hubbed on pivot 11, namely the first hinge plate 12 and the second hinge plate 13 are as rotated to same plane two panels hinge plate 62 of the prior art, and both are positioned at the axial both sides of pivot 11.
