Description

The special-purpose Picking-preventing hinge of security door

The utility model relates to a kind of hinge that connects usefulness, the special-purpose Picking-preventing hinge of especially a kind of security door.

At present hinge and the furniture hinge shape used of security door is basic identical, thus since connection be that metalwork thickness has increased.This thickening hinge all is whole downhand welding on the link position in the security door outside, therefore uses general purpose tool just can be easy to make security door ineffective hinge destruction.

The purpose of this utility model is for a kind of hinge that is installed in the security door medial surface is provided.

The utility model is made up of rotating shaft 2 and support 4, and the cross section that it is characterized in that support 4 is a U-shaped, and the dual-side of support 4 has aduncate axle sleeve 3, and rotating shaft 2 is contained in the axle sleeve 3, and the two ends of rotating shaft 2 have connector 1.

Below in conjunction with accompanying drawing architectural feature of the present utility model is further specified.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the rear elevation of Fig. 1.

Fig. 4 is the vertical view of Fig. 1.

Fig. 5 is the A-A sectional view of Fig. 1.

Each part in the accompanying drawing is made by metal material, belongs to general simple machine and implements easily.

The maximum ga(u)ge of hinge should be near the height of doorframe and door leaf inner convex platform, and making it connect the back becomes formation state with door leaf.When hinge is installed, at first the chimb of doorframe and large and small door leaf inner face one side respectively should be opened an elongated opening in the position up and down, the length of this opening is identical with support 4 length, 2 of the rotating shafts of support 4 are placed in this opening, and weld fixing by the connector in the rotating shaft 21, through welding fixing back door leaf can be that outwards rotate at the center with hinge rotating shaft 2, and result of use is better after trial assembly, interior outside all very smooth.Because this hinge is installed in the inboard of door, can prevent from effectively to open the incident generation of security door by destroying hinge, the theftproof of security door is further improved.
