CN2030247U - Theft-proof hinge - Google Patents

Abstract

The utility model provides an anti-theft hinge used for daily life, particularly for doors and windows opening outward. The utility model only slightly improves laminas and not alters the assemble form of the hinge pin shaft on the basis of the fabrication process of the existing hinges. Laminas overlap together by using the convexities or pits arranged on the laminas when two laminas combine together. Even if the pin shafts are driven out, the laminas can not generate opposite slippage. The utility model can prevent the occurrence of stolen accidents caused by the opening of windows or doors owing to the driving out of the pin shafts. The utility model has the advantages of simple structure, easy fabrication and high reliability.

Description

Theft-proof hinge

The utility model relates to the Theft-proof hinge that a kind of daily life is used, and is specially adapted on the outside door of opening, the window.

Hinge commonly used in the daily life at present is by two blades and hinged the forming of bearing pin.Bearing pin in the middle of this hinge generally adopts the mode of grafting to fix, and is easy to bearing pin to make hinge lose hinged effect by getting the blade axis hole from an end.The door and window of existing dwelling house, for preventing because of the door and window distortion is difficult for pushing open, the people can't come out from indoor, often door, window is made the form of outside unlatching.But after the used hinges of this door and window was installed, bearing pin exposed outdoor, is easy to bearing pin is laid down, and makes door and window easily by breakdown, and stolen accident takes place.

The purpose of this utility model provides a kind of Theft-proof hinge, and it is not only simple in structure, makes easily, and uses reliable.

The purpose of this utility model is achieved in that on the basis of existing hinge manufacturing process, do not change the assembling form of hinge pin, only the blade with hinge improves a little, make when lumping together after two blade installation, utilize projection on it or pit that two blades are cooperatively interacted and overlap.Even bearing pin is struck off, two blades can not produce relative slippage yet, can prevent because of bearing pin be struck off breakdown door, window, and robbed or burgled accident takes place.

Because the utility model only increases a projection or pit on blade, only change the mold of suppressing blade a little and get final product, so be easy to make.Two blades lump together, and protruding, recess strong bonded can not be separated from together each other.Therefore, when bearing pin was laid down, the hinge that is installed on door, the window can be not ineffective yet, can not be destroyed and robbed or burgled because of hinge.

The utility model is described in further detail below in conjunction with accompanying drawing.

Describe concrete structure of the present utility model in detail according to Fig. 1～8.This hinge is assembled into one by two blades and bearing pin assembling form routinely.These two processing of leaves also must make to process projection, pit on the blade except that by the normal general pitch-row boring.Specific practice is: structure as shown in Figure 1, and only wherein a slice blade flanging gets final product; Structure can go out groove with a slice blade processing as shown in Figure 3, and another sheet blade processing goes out raised line, and structure can go out pit with a slice blade processing as shown in Figure 5; Another sheet processes boss; Structure can go out pit with a slice blade processing as shown in Figure 5, and another sheet blade processing goes out fin.

When door, window are installed, as long as a slice blade with the utility model band flanging or projection, be screwed on door, window, another sheet blade is screwed on doorframe or window frame, and process pit in the relevant position, match with the blade of band projection, make close to the doorstep, during window, this hinge closely cooperates and overlaps.

Existing biaxial hinge or other hinge of being made up of bearing pin, its blade all can adopt the form of structure of above-mentioned blade.

Claims (5)

1, a kind of Theft-proof hinge that is assembled into by blade and bearing pin is characterized in that being shaped on the described blade projection or the pit that cooperatively interact and overlap.

2, Theft-proof hinge according to claim 1 is characterized in that can making on the described blade groove or the raised line that cooperatively interact and overlap.

3, Theft-proof hinge according to claim 1 is characterized in that can making on the described blade pit or the boss that cooperatively interact and overlap.

4, Theft-proof hinge according to claim 1 is characterized in that can making on the described blade pit or the fin that cooperatively interact and overlap.
