Description

Adjustable ball supports hinge

The utility model relates to a kind of adjustable ball and supports hinge, particularly a kind of hinge that is used on the metal anti-theft safety door.

The hinge that various types of metal anti-theft door adopted of Sheng Chaning is different in the market, and what have rivets with rivet, and the weldering that has is dead, and most hinge all exposes, and very easily stolen molecule destroys hinge with simple tool, forces open the door; By GA25-92 " anti-theft safety door general technical specifications " requirement, security door is necessary for metal construction, and every door frame Men Douying is more than 60Kg, because safety door is heavier, and its switch is dumb, noise is big like this; And after using for many years, the wearing and tearing sinkage is arranged, cause the lower edge of door leaf and lower frame to produce friction, the switch inconvenience that brings safety door.

The purpose of this utility model provides that a kind of hinge does not expose, switch flexibly, the upper-lower position of door leaf can regulate with avoid and lower frame between produce the hinge of friction.

The utility model comprises door leaf fixed head, doorframe fixed head and hinge axis, one side of doorframe fixed head has upper and lower two sleeve pipes, one side of door leaf fixed head also has sleeve pipe, the sleeve pipe of door leaf fixed head is between the upper and lower sleeve pipe of doorframe fixed head, hinge axis is inserted in each sleeve pipe, and the door leaf fixed head can be around the relative doorframe fixed head rotation of hinge axis like this.Doorframe fixed head and door leaf fixed head and the sleeve pipe on it are fixedly connected on tangential direction, and the same side of sleeve pipe formed plane when being positioned at two fixed heads and becoming the plane, avoiding after this hinge is installed on the security door, and the exposing of hinge sleeve pipe.The setting of casing of doorframe fixed head is a blind hole, has a diameter to be slightly less than the steel ball of blind hole diameter in the blind hole, and the terminal part of hinge axis is inserted in the blind hole, and the last term end is supported on the steel ball, can make the door leaf switch flexible like this.The sleeve pipe of door leaf fixed head is two parts up and down, top is divided into threaded sleeve, the bottom is divided into general light sleeve pipe, the hinge axis mid portion is a thread spindle, it matches with threaded sleeve, the door leaf fixed head have one to adjust nut up and down between two sleeve pipes, the same threaded sleeve in spiral shell footpath of nut, be enclosed within on the hinge thread spindle, be used to adjust and be installed on the upper-lower position of door leaf on the door leaf fixed head.

The utlity model has advantages such as safe and reliable, simple in structure, easy for installation, practical, can be widely used in the installation of all kinds of anti-theft safety doors and common door.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is the front view of this hinge;

Fig. 2 is the vertical view of this hinge;

Wherein 1 is hinge axis, and 2 is the door leaf fixed head, and 3 is threaded sleeve, and 4 for adjusting nut, and 5 is the light sleeve pipe, and 6 is steel ball, and 7 is the doorframe fixed head, and 8 is setting of casing, and 9 is last sleeve pipe.

Hinge axis (1) is processed with No. 45 steel, and plating zinc on surface is handled, and the cross section at hinge axis (1) top is square or regular hexagon, so that rotate hinge axis (1) with spanner.All sleeve pipes keep wall thickness 4mm, and threaded sleeve (3), sleeve pipe (5) and setting of casing (8), last sleeve pipe (9) adopt method and door leaf fixed head (2), the doorframe fixed head (7) of welding to be fixed together respectively.On door leaf fixed head (2) and the doorframe fixed head (7) several bellmouths are arranged all, be separately fixed on door leaf and the doorframe with screw by these bellmouths.

For making the door leaf open and close more flexible, in setting of casing (8) blind hole of placing steel ball (6), insert the glycerine of lubricate, make glycerine be enclosed in steel ball (6) on every side.

Adjust nut (4) and adopt round nut, the same sleeve pipe of its external diameter on nut (4) external peripheral surface, is drilled with four holes equably, is used to rotate this nut.

Two fixed heads (2) (3) are adjusted after good through hinge axis (1), rotate up and adjust nut (4), make it tightly to withstand threaded sleeve (3), have so just fixed the upper-lower position of door leaf.

If after long-term the use, door leaf sinks, when occurring between door leaf and the lower door frame friction phenomenon taking place, the user can adopt following method that this is adjusted: insert with iron wire in the aperture of adjusting nut (4) periphery, nut (4) is adjusted in rotation, itself and threaded sleeve (3) are unclamped, turn hinge axis (1) with spanner then, make door leaf fixed head (2) be with door leaf to move up, adjust to correct position after, to adjust nut (4) and upwards tighten, security door is just adjusted and is finished.

Claims (3)

1. an adjustable ball supports hinge, comprise door leaf fixed head, doorframe fixed head and hinge axis, one side of doorframe fixed head has upper and lower two sleeve pipes, one side of door leaf fixed head also has sleeve pipe, the sleeve pipe of door leaf fixed head is between the upper and lower sleeve pipe of doorframe fixed head, hinge axis is inserted in each sleeve pipe, it is characterized in that:
