Abstract

The utility model relates to a door hinge structure of a strong box, comprising a hinge sleeve (2) which is fixed at the back of a door plate (1), and a hinge axis (3) which is inserted in the hinge sleeve (2). The door hinge structure is characterized by also comprising a hinge cover (4) which is fixed at the back of the door plate (1) and covers the hinge sleeve (2) inside. The hinge cover which covers the hinge sleeve inside is fixed at the back of the door plate, so that the hinge sleeve is hidden, and the back surface of the door plate is more attractive; the hinge cover isolates the hinge sleeve from the external environment, thus effectively protecting that the door hinge is not damaged by foreign objects, and preventing that the relative rotation between the hinge axis and the hinge sleeve is affected as dust enters the hinge sleeve.

Description

The door hinge structure of strongbox

Technical field

The utility model relates to a kind of accessory that is used for security door, relates in particular to a kind of door hinge structure of strongbox.

Background technology

Strongbox generally comprises casing that has doorframe and the door-plate that is hinged on doorframe one side by door hinge, the kind of door hinge roughly has two kinds, a kind of is the vane type hinge, generally comprise blade that has shaft hole and lower blade that structure is mutually symmetrical, wherein blade is installed on the door-plate, lower blade is installed on the doorframe, one rotating shaft is passed in the shaft hole on blade and the lower blade simultaneously 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.Another kind is a pivot hinge, generally comprise hinge sleeve and hinge axis, wherein hinge axis is plugged in the pivot hole following on the doorframe, one end of hinge axis exposes, hinge sleeve is set on the hinge axis that exposes outside pivot hole again, at last hinge sleeve and panel are fixed, the shaft type hinge arrangement can be hidden in hinge in the door-plate, and safety is better.

As a patent No. is a kind of Hinge for safe the Chinese utility model patent " Hinge for safe " of ZL96232288.1 (notification number is CN2311593Y) has disclosed, by upper hinge, compositions such as following hinge and hinge axis, to descend hinges fixing to fix on the safe body during use, be equipped with blind hole on following hinge and the following hinge, wherein descend hinges fixing to fix on the doorframe upper side frame and lower frame of strongbox, the doorframe of following hinge is the equal of at the pivot hole that is arranged on the doorframe, upper hinge is fixed on the door-plate back side, and hinge axis becomes flexible in the blind hole that is plugged in down hinge and following hinge simultaneously.

And for example a patent No. is that the Chinese utility model patent " a kind of security door hinge means " of ZL02247680.6 (notification number is CN2560719Y) has disclosed a kind of like this security door hinge means, comprise upper hinge, following hinge, it is characterized in that: up and down hinge be installed in respectively the door directly over under, and be concealed structure, each hinge all is made up of hinge seat, hinge axis and axle cap, axle cap is fixed and is had with doorframe between pivot hole hinge axis and hinge seat to being threaded, and fix by lock screw, the high abrasion copper sheet is arranged between hinge axis and axle cap.

More than two patents disclose two kinds of pivot hinge structures exactly, all there are such problem in these two kinds of structures and conventional pivot formula hinge, be that hinge sleeve was exposed at the door-plate back side outward after door-plate was opened, influence attractive in appearance, and dust also easily enters in the hinge sleeve, and influence the rotation of hinge axis, and foreign object direct collision hinge sleeve and damage door hinge.

Summary of the invention

Technical problem to be solved in the utility model is the door hinge structure that a kind of strongbox that hinge sleeve can be covered with is provided at above-mentioned prior art present situation; this structure can make the door-plate back side more attractive in appearance; effective shutter hinge, and prevent that dust from entering in the hinge sleeve.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of door hinge structure of strongbox, include the hinge sleeve that is fixed on the door-plate back side, and be plugged in hinge axis in the hinge sleeve, it is characterized in that: also include be fixed on the door-plate back side hinge sleeve is covered with knuckle guard in it.

Above-mentioned knuckle guard comprise by backboard, base plate, outer panel and interior plate surround can be with the ccontaining framework in it of hinge sleeve, the front of outer panel is along having the side installing plate that turns up, have first perforation on the side installing plate, having screw to pass this first perforation back fixes with door-plate, the lower edge of base plate has the lower installation board that turns up, have second perforation on the lower installation board, have screw to pass the second perforation back and fix with door-plate.

The mentioned hinge cover structure simply is convenient to make, can form by the Sheet Metal Forming Technology bending forming, this knuckle guard can also be installed in it hinge sleeve is fine, and this knuckle guard is fixed together this knuckle guard and door-plate by two installing plates, so can easily knuckle guard and door-plate be fixed together.

Above-mentioned first perforation is bar hole, and the length direction of this bar hole is consistent with the length direction of side installing plate, and described second perforation is circular hole.Because first perforation is bar hole, so the height and position of the relative door-plate of knuckle guard can be finely tuned, guarantee the inner face applying of the end face and the doorframe of knuckle guard on short transverse, prevent that effectively dust from entering the hinge sleeve that is arranged in knuckle guard.

Compared with prior art; advantage of the present utility model is: be fixed with at the back side of door-plate hinge sleeve is covered with knuckle guard in it; make hinge sleeve not expose; the door-plate back side is more attractive in appearance; this knuckle guard is hedged off from the outer world hinge sleeve; effectively the shutter hinge is not subjected to the damage of foreign object, and prevents dust from entering in the hinge sleeve and influence relatively rotating between hinge axis and the hinge sleeve.
