Abstract

The utility model discloses a concealed hinge with axial adjustment. The hinge is provided with a sliding plate, both sides of the sliding plate are provided with clamping grooves which limit the axial movement of adjusting screws, a plate seat is designed as a U-shaped structure, both sides of the plate seat are provided with ear plates, and the ear plates are provided with screw thread holes which are used for loading the adjusting screws. The hinge is arranged in a hinge box through an upper adjusting axle and a lower adjusting axle, the lower edge of the hinge box is fixed with a screw nut, the upper adjusting axle and the lower adjusting axle are designed as step axles, a large diameter axle is lathed with a screw thread which is matched with the screw nut on the hinge box, and the screw nut is provided with a tight screw. The gap between a door leaf and a door frame can be adjusted to an optimum gap by the utility model, and the utility model is especially suitable for the theftproof doors which are made of steel.

Description

Axially can regulate built-in hinge

The utility model relates to a kind ofly axially can regulate built-in hinge.

Hinge be important link on the furniture door and window please referring to Fig. 4, it is made up of hinge 6, bearing pin 7 and hinge box 8; Door leaf and doorframe, sash generally is connected with hinge with window frame, and having relatively high expectations of security door requires pick-proof, is connected with built-in hinge between security door and door leaf and doorframe.Above-mentioned articulated link mechanism all exists a common shortcoming, be exactly not adjust link, so, although door leaf and doorframe are all according to the dimension precision requirement manufacturing of zero (portion) part, but the gap between assembling back door leaf and doorframe surpasses 4mm mostly, two hinges up and down of being provided with often have only a hinge load-bearing between door and doorframe, so this hinge is deformed so that influence use.Make between hinge and hinge box contact surface mutual friction mutually during the open and close door leaf and produce wearing and tearing, so door leaf sinks in use for some time, when may wear to a certain degree, door leaf just can't normally cut out.At present, in door and window is installed to the processing of the problems referred to above generally with file, mill finishing, its shortcoming: the one, influence product quality, the 2nd, work efficiency is lower, the 3rd, labour intensity greatly,

The purpose of this utility model is to overcome above-mentioned deficiency and design a kind ofly axially can regulate built-in hinge by what adjustment screw, up-down adjustment axle, panel seat, hinge and hinge box were formed.

The utility model content is a kind of axially can regulate built-in hinge, comprise hinge, hinge box and bearing pin, by bearing pin hinge, hinge box are coupled together, it is characterized in that: hinge is provided with slide plate, and the both sides of slide plate are provided with the axially movable draw-in groove of restriction adjustment screw; Panel seat is made as " U " type structure, the both sides of panel seat are provided with otic placode, otic placode is provided with the screwed hole of debuging the joint screw, hinge is loaded in the hinge box by the up-down adjustment axle, the bottom of hinge box is fixed with nut, the up-down adjustment axle is designed to the step axle, and get on the bus screw thread and match with nut on the hinge box of major diameter axle is equipped with the holding screw of locking up-down adjustment axle usefulness on the nut.

The utlity model has following advantage:

1. when door leaf and doorframe gap are big, can screw adjustment screw, make panel seat shift to hinge box (doorframe) with door leaf, the gap is dwindled, reach the GB requirement, when upper and lower gap is inconsistent between door leaf and doorframe, also can adjust adjustment screw and make upper and lower gap unanimity, easy to adjust, alleviated labour intensity, and outward appearance is clean and tidy.

In installing the door leaf upper-lower position improper or use in during with the sinking of hinge box wearing and tearing door leaf, can adjust the up-down adjustment axle because of hinge, door leaf can be lifted, easy and simple to handle.

Description of drawings:

Fig. 1 is the utility model schematic diagram;

Fig. 2 is the hinge component schematic perspective view;

Fig. 3 is the A-A sectional view of Fig. 1;

Fig. 4 is a hinge box part perspective exploded view.

Further specify the utility model below in conjunction with drawings and Examples.

Please referring to Fig. 1, Fig. 2, Fig. 3, axially can regulate built-in hinge by adjustment screw 5, holding screw 11, hinge 6, up-down adjustment axle 7, panel seat 1 and hinge box 8 are formed, hinge box bottom is welded with nut 13, up-down adjustment axle 7 is made as the step axle, step axle top small diameter shaft is passed pan and is bearing in the through hole that cuts with scissors box top, got on the bus screw thread and match of the major diameter axle of step axle with nut 13, major diameter axle axle head is provided with by hexagonal hole 12, for screwing with interior six side's planks, the step surface of step axle is supporting door leaf, can drive door leaf when rotating the up-down adjustment axle and move up and down; Available holding screw 11 locking panel seats 1 are " U " type sheet metal component after the door leaf position is mixed up, respectively be provided with three projections 3 on the biside plate, its lower surface forms the track confined planes 10 of slide plate 2, the every side of panel seat right-hand member also is provided with two otic placodes 4, otic placode is provided with the screwed hole that adjustment screw 5 is installed, panel seat and on otic placode and projection can be one-body molded through punching press by steel plate; Hinge 6 outsides are welded with the slide plate 2 of " " font, and the draw-in groove that forms restriction adjustment screw head between two projection 9, two projections is respectively established in the both sides of slide plate, so when rotating adjustment screw 5, panel seat is moved together with door leaf.

The utility model uses adjustment screw 5 can make the door leaf move left and right, by regulating up-down adjustment axle 7 door leaf is moved up and down, thereby makes the place, space between door leaf and doorframe reach best fit clearance.
