Abstract

Disclosed is a hidden gemel for a security door, comprising gemel saddles. The hidden gemel of the utility model is provided with two symmetric gemel saddles which are characterized in that the middle parts are concave and the upper and the lower parts are installation fixing faceplates. The two symmetric gemel saddles are connected by a long connecting piece in a cross way, that is: bearing plates are alternatively embedded in the concave parts, short connecting pieces are arranged at the lower place between the bearing plates and are pined by lower fixing pins, the horizontal part of the long connecting piece is arranged on the upper parts of the short connecting pieces and is pined by upper fixing pins, the vertical part of the long connecting piece is disposed at the upper place between the bearing plates and is pined by inner fixing pins, and the long connecting piece is pined by a middle fixing pin. The installation fixing faceplates of the gemel saddles are provided with two circular bead rectangular installation holes. The lower fixing pins are the same as the inner fixing pins and the upper fixing pins are the same as the middle fixing pins. The utility model adopts two symmetric gemel saddles and the gemel saddles are provided with two circular bead rectangular installation holes at fixed places, so the utility model is convenient to install. The utility model is simple in structure with a plurality of identical components, therefore the utility model is easy to manufacture.

Description

The security door blind hinge

Affiliated technical field

The utility model relates to door and window connector technical field, refers in particular to a kind of security door blind hinge.

Background technology

At present, security door is generally all used blind hinge, because blind hinge has theftproof performance preferably.As Chinese patent 00255746.0 disclosed " security door blind hinge ", it is to be made of hinge seat and hinge bodies, and hinge bodies one end links to each other with doorframe by mandrel, the other end links to each other with door leaf, adjustment is adjusted by the adjustment bolt in the mandrel, and structure is complicated, adjusts trouble.As Chinese patent 01238456.9 " anti-theft safety door blind hinge ", constitute by hinge seat and hinge bracket, hinge seat is fixedly mounted on the doorframe, and hinge bracket is fixedly mounted on the door leaf.Not only fixedly the structural member of doorframe and door leaf is different for these blind hinges, make and make inconvenience, and when mounted must be very careful, must be very accurate when determining installing hole, inaccurate will the punching again, in the time of serious even security door is scrapped, this is because these blind hinges itself move up and down and do not have an adjustability.

Summary of the invention

The purpose of this utility model is to provide a kind of security door blind hinge, and it is simple in structure, and is easy to manufacture, easy for installation, and is adjustable up and down.

For achieving the above object, the solution that the utility model is taked is: a kind of security door blind hinge, comprise hinge seat, it is characterized in that blind hinge has the hinge seat of two symmetries, be pit in the middle of the described hinge seat, up and down for installing and fixing panel, the hinge seat that connects two symmetries by long brace interleaved mode, the i.e. alternate base plate that is embedded with in pit, after short brace is placed in bottom between the base plate with under fixedly pin it, after the horizontal end of long brace is placed on top between the short brace, use fixedly pin it, between base plate top place the perpendicular end of long brace afterwards with interior fixedly pin it, with in the fixing long brace of pin.

Install and fix at described hinge seat and to have two round rectangle installing holes on the panel.

Described steady pin is the same with interior steady pin down, and last steady pin is the same with middle steady pin.

Because the utility model is with the hinge seat of two symmetries, with regard to do not need to assert which is installed on the doorframe, which is installed on the door leaf, makes easy for installation.Owing to have two round rectangle installing holes on the hinge seat permanent position, if on doorframe or the door leaf installing hole upper-lower position very inaccurate yet needs punch again, fixing again after blind hinge is adjusted up and down.The utility model is simple in structure, and different part is few, and is therefore easy to manufacture.

Description of drawings

Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.

Fig. 1 is the cut-away section structural representation of present embodiment.

Fig. 2 is the A-A view of Fig. 1.

Among the figure: 1, round rectangle installing hole, 2, install and fix panel, 3, hinge seat, 4, base plate, 5, short brace, 6, long brace, 7, interior steady pin, 8, middle steady pin, 9, go up steady pin, 10, time steady pin, 11, pit.

The specific embodiment

As depicted in figs. 1 and 2, a kind of security door blind hinge, comprise hinge seat 3, it is characterized in that blind hinge has the hinge seat 3 of two symmetries, be pit 11 in the middle of the described hinge seat 3, up and down for installing and fixing panel 2, the hinge seat 3 that connects two symmetries by long brace 3 interleaved modes, the i.e. alternate base plate 4 that is embedded with in pit 11, bottom between the base plate 4 place short brace 5 backs with under steady pin 10 bolts it, after long brace 6 horizontal ends are placed on top between the short brace 5, use steady pin 9 bolts it, between base plate 4 top place long brace 6 perpendicular end backs with interior steady pin 7 bolts it, the long brace 6 of steady pin 8 bolts in using.

As shown in Figure 1, install and fix at described hinge seat and have two round rectangle installing holes 1 on the panel 2.

See Fig. 1 and Fig. 2, described down steady pin 10 is the same with interior steady pin 7, and last steady pin 9 is the same with middle steady pin 8.
