Abstract

The utility model relates to an adjustable ball bearing hinge which belongs to a connecting piece of the architectural hardware. A pin shaft with threads are inserted into a base to touch ball bearings after penetrates through a shaft sleeve with threads. The pin shaft rotates left and right to drive the shaft sleeve to move. After the height of a door or a window is adjusted, the utility model is locked by positioning screws. The utility model is particularly suitable for bigger doors, bigger windows and industrial cabinets and has the advantages of adjustable height of a door or a window, flexible rotation, opening and closing labour saving, etc.

Description

Adjustable ball hinges

The utility model relates to a kind of improved architectural hardware connector, and specially referring to is a kind of adjustable connector.

In the employed connector, as common hinge and axle core hinge etc., custom one-tenth loose-leaf all has two blocks of page or leaf plates (being made up of axle sleeve and fixed head) and a bearing pin to be formed by connecting on existing door, window and doorframe and various cupboard, frame.As Fig. 1, Fig. 2 and shown in Figure 3, so that various door, window freely rotate around the bearing pin of hinge.But when on heavier door, using this hinge, often there is door and window can not correctly be installed on the frame and opens and closes shortcomings such as hard.

The purpose of this utility model just be to provide a kind of can adjustment doors, the setting height(from bottom) of window and open and close labour-saving adjustable ball hinge.

The utility model is made up of base and axle sleeve, (or base and axle sleeve of band fixed head), dog screw, bearing pin and ball.Ball is packed in the unthreaded hole of base, after being with externally threaded bearing pin to screw in tapped axle sleeve, insert again in the unthreaded hole of base and contact with ball, at this moment, according to the installation situation of door, window, the left rotation and right rotation bearing pin makes axle sleeve drive door or window is subjected to displacement, after adjusting, with dog screw locking, reach the purpose of adjustment doors, window setting height(from bottom).

According to the adjustable ball hinge that the utility model is made, have make door, the window setting height(from bottom) is adjustable, rotates flexibly, opens and closes advantages such as laborsaving, be suitable for especially on large-scale door, the window.Below with reference to accompanying drawing the utility model is done further detailed description.

Fig. 4 is a specific embodiment of the present utility model, and a unthreaded hole 12 and fixing threaded hole 1,15 are arranged on the base 2, and there are internal thread 11 and fixing threaded hole 9,10 and positioning screw hole 6 in axle sleeve 4 inside; The first half of bearing pin 3 has and the corresponding external screw thread 7 of axle sleeve 4 internal threads 11, and there is a word (or+word) groove 8 its upper end, and there is a hemispherical recess 13 its lower end; Be screwed into the fixing threaded hole 1 of base 2 respectively by the circular hole (not shown) of casing and door with sunk screw, 15 and the fixing threaded hole 9 of axle sleeve 4, in 10, then ball 14 is packed in the unthreaded hole 12 of base 2, bearing pin 3 screws in axle sleeve 4 and inserts in the unthreaded hole 12 of base 2, part ball 14 is entered in the hemispherical recess 13 of bearing pin 3 bottoms, if the height position of door is incorrect, at this moment, just a word (or cross) shape screwdriver can be put into one word (or cross) groove 8 of bearing pin 3 upper ends, left rotation and right rotation is subjected to displacement axle sleeve 4 relatively, driving door or window moves up and down, after adjusting the position, fixing tightening in the dog screw 5 screw-in positioning screw holes 6, at this moment the friction between bearing pin 3 and the base 2 is rolling friction, therefore door, the keying of window is just especially laborsaving.

Fig. 5, Fig. 6 are another embodiment of the present utility model, it just adds the base 2 of the foregoing description and axle sleeve 4 respectively or extends a fixed head 16 and 20, simultaneously the fixing threaded hole 9,10 of the fixing threaded hole 1,15 of base 2 and axle sleeve 4 is replaced by the circular hole on fixed head 16 and 20 17,18,19 and 21,22,23 respectively, other is constant, so both can equally with general hinge use, possessed advantage described in the utility model again.

At last, we are illustrated accompanying drawing of the present utility model.

Fig. 1, Fig. 2 are respectively the schematic diagrames of common hinge and Hinge with pin, Fig. 3 is the elevation of another hinge, Fig. 4 is the sectional arrangement drawing of the utility model embodiment, and Fig. 5, Fig. 6 are the base 2 of the band fixed head 16,20 of another embodiment of the present utility model, the sectional view of axle sleeve 4.Wherein: the 1, the 15th, fixing threaded hole, the 2nd, base, the 3rd, bearing pin, the 4th, axle sleeve, the 5th, dog screw, the 6th, positioning screw hole, the 7th, bearing pin external screw thread, the 8th, a word (or cross) groove of bearing pin 11 upper ends, 9, the 10th, fixing threaded hole, the 11st, the internal thread of axle sleeve, the 12nd, the unthreaded hole on the base 2, the 13rd, the hemispherical recess of bearing pin 3 bottoms, the 14th, ball, the 16, the 20th, fixed head, 17,18,19 and 21,22,23 is respectively the circular hole on fixed head 16 and 20.

Claims

1, a kind of adjustable ball hinge is characterized in that it by the base 2 that fixing threaded hole 1,15 (or band fixed head 16) and unthreaded hole 12 are arranged, has the axle sleeve 4 of fixing threaded hole 9,10 (or band fixed head 20), and dog screw 5 and bearing pin 3 and ball 14 are formed.

2, by the described adjustable ball hinge of claim 1, it is characterized in that axle sleeve 4 has internal thread 11 and has a positioning screw hole 6 in a side; One side of bearing pin 3 has and axle sleeve 4 internal threads 11 corresponding external screw threads 7, and its end has a word (or+word) groove 8; There is a hemispherical recess 13 that is slightly larger than ball 14 radiuses the another side bottom.

3, by claim 1,2 described adjustable ball hinges, it is characterized in that ball 14 puts into the unthreaded hole 12 of base 2, again bearing pin 3 being screwed in axle sleeve 4 backs inserts in the unthreaded hole 12 of base 2, and part ball 14 is entered in the hemispherical recess 13 of bearing pin 3, then making axle sleeve 4 fixing in the dog screw 5 screw-in positioning screw holes 6.
