Abstract

The utility model relates to a double-column built-in hinge which comprises double columns and a base of a column bore, wherein the two columns are connected by an n-shaped connecting rod and inserted in the protection boxes of the columns. A spring is arranged between the connecting rod and the spring hangers of the protection boxes. A raising connection point is arranged at the connecting rod above a second column and connected with a lock core connecting rod of a lockset, and the base of the column bore is provided with a two-eyed column bore corresponding to the columns. After a normally operated first column of a hinge is sawed, the second column is slid in the corresponding column bore to connect a door leaf and a doorframe again, and the person who commits a crime can not saw for a second time, and the theftproof performance is excellent. In addition, the door leaf normally connected by the first column has the advantages of easy and flexible opening and good air tightness.

Description

Two column concealed type hinges
The utility model belongs to door leaf hinge class, especially a kind of two column concealed type hinges that are used for the flat opening security door.
At present, the hinge that the flat opening security door uses mostly is common hinge, is installed between door leaf and the doorframe.The shortcoming that this hinge exists is: outside 1. the hinge of security door is exposed to, be breakdown in case suffer sawing or people, especially use " returning the very compound cage plate of titanium molybdenum steel " to make the case instrument, can easily door leaf and doorframe be broken away from, security door promptly loses its anti-theft feature; 2. the long-term switch of common hinge can cause that door leaf is sagging, the phenomenon of torsional deformation; 3. use the general airtight performance of security door of common hinge relatively poor.
It is a kind of after the hinge pillar that connects door leaf and doorframe is by sawing that the purpose of this utility model is to provide, and can play two column concealed type hinges of interconnect function once again.
For achieving the above object, the technical scheme that the utility model is taked is: this pair column concealed type hinge is made up of column, post thorax base two parts, two root posts by "
Figure Y0020399600031
" connection of type connecting rod, be inserted in column and protect in the box, " " the type connecting rod under, be respectively equipped with spring strut directly over protecting box, be equipped with spring between the upper and lower spring strut, wherein the connecting rod place, top of II column is provided with the lifting contact, is connected with the lock core connecting rod of lockset; Post thorax base is provided with and corresponding two the post thoraxes of column.
Be further to strengthen theftproof performance, post thorax base and column protect filling in the box a kind of good impact intensity that has---phosphoguanidine gel polymerisation body, directly destroys hinge upright to prevent autogenous cutting.
Two column concealed type hinges by such scheme manufactures and designs are welded on respectively in door leaf and the doorframe, all can't see hinge during switch, and are compact attractive in appearance.When normal mounting is used, after the post thorax engagement corresponding of I column, door leaf and doorframe gap can be transferred in two millimeters, have good airtight performance with it, and unlatching is very light and handy flexibly, has effectively prevented sagging, the torsional deformation phenomenon of door leaf that the long-term switch of common hinge causes.When the hinge upright of operate as normal suffers that sawing or people are for after the breakdown, the column connecting rod is just upspring, spring is once upspringing, just break away from pillar automatically, meanwhile, the II column just can slip into corresponding post thorax, thereby door leaf and doorframe are reconnected, when having only owner with key breakdown door, the II column just can leave the post thorax.When owner overhauls, only need to change a secondary standby hinge upright and a column connecting rod, door just can recover to use.Because the position, dead angle of sawing that the spacing that two root posts are set design " is returned the very compound cage plate of titanium molybdenum steel " each other, being the case personnel can't use this instrument to carry out two degree sawings, post thorax base and column protect to irritate in the box in addition " the phosphoguanidine gel polymerisation body " with good impact intensity, so this hinge has premium properties such as anti-gas cutting and brill striking destruction.
Fig. 1 is the structural representation of two column concealed type hinge upright parts;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation that two column concealed type hinge pillar thoraxs are divided;
Fig. 4 is the vertical view of Fig. 3;
Fig. 5 is two column concealed type hinge practical application figure.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Among the figure: the 1-I column; The 2-spring strut; The 3-spring; 4-column connecting rod; The 5-II column; The 6-column protects box; The 7-II column promotes contact; 8-post thorax base; 9-I column post thorax; 10--II column post thorax; 11-phosphoguanidine gel polymerisation body.Among Fig. 1,2, two root posts 1,5 by " " type column connecting rod 4 is threaded, insert column and protect in the box 6, " " type column connecting rod 4 under, column protect box 6 directly over be respectively equipped with spring strut 2, be equipped with spring 3 between the upper and lower spring strut 2, wherein: top connecting rod 4 places of II column 5 are provided with and promote contact 7, are connected with steel wire with the lock core connecting rod of lockset.Column protects to irritate in the box 6 a kind of good impact intensity that has---phosphoguanidine gel polymerisation body 11, directly destroys hinge upright 1,5 to prevent autogenous cutting.
Among Fig. 3,4, post thorax base 8 is provided with and column 1,5 corresponding two post thoraxes 9,10.Also irritating in the post thorax base 8 has---phosphoguanidine gel polymerisation body 11.
Among Fig. 5, two column concealed type hinges are welded in door leaf and the doorframe.
