Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, a metal connector for conveniently adjusting the keyhole spacing according to the present invention includes mutually symmetrical frame-shaped left hinges 1 and frame-shaped right hinges 8 connected by rotating shafts 7; The central symmetrical positions of the frame-shaped left hinge 1 and the frame-shaped right hinge 8 are respectively provided with rectangular square holes A15 and rectangular square holes B9; the upper left side of the rectangular square hole A15 of the frame-shaped left hinge 1 and The left hinge upper keyhole device and the left hinge lower keyhole device are symmetrically arranged at the bottom; The buttonhole device under the page is matched with the upper buttonhole device on the right hinge and the lower buttonhole device on the right hinge with the same structure; There is a left keyhole groove A above the top of the left side of the square hole A15, and the left side of the left keyhole groove is respectively provided with a connecting strip 2 on the left side with a groove and a connecting strip 6 on the right side with a groove; The upper left keyhole piece 4 is arranged in the left keyhole groove, and the upper left keyhole piece 4 is stuck in the groove of the upper connecting bar 2 on the left side and the upper connecting bar 6 on the right side; A number of miniature springs A5 are evenly arranged, and the plurality of miniature springs A5 are clamped in the groove of the upper connecting bar 6 on the right side; There is a left keyhole groove B under the left bottom of the hole A15, and the left side of the left keyhole groove B is respectively provided with a grooved left lower connecting strip 14 and a grooved right lower connecting strip 10; A left lower keyhole piece 12 is arranged in the left keyhole groove B, and the left lower keyhole piece 12 is clamped in the grooves of the left lower connecting bar 14 and the right lower connecting bar 10; A number of miniature springs B11 are evenly arranged on the side, and the plurality of miniature springs B11 are clamped in the groove of the lower connecting bar 10 on the right side.

A serration A3 is provided on the right side of the left upper connecting bar 2 , and a serration C engaged with the serration A3 is provided on the left side of the left upper escutcheon 4 .

A sawtooth B13 is provided on the right side of the left lower connecting bar 14 , and a sawtooth D meshing with the sawtooth B13 is provided on the left side of the left lower escutcheon 12 .

When the present invention is in use, the upper left escutcheon 4 and the lower left escutcheon 12 are all provided with keyholes; when the distance between the upper left escutcheon 4 and the lower left escutcheon 12 on the left hinge When shortening, since some miniature springs A5 are arranged on the right side of the left upper escutcheon 4, they can move slightly to the right, so that the serrations on the left side of the left upper escutcheon 4 are connected with the left side of the upper connecting bar 2 on the right side. The sawtooth A3 loosens the engagement, moves downward to a suitable distance and then releases. At this time, due to the recovery effect of the miniature spring A5, the upper left keyhole piece 4 engages with the upper left connecting strip 2 again, so that it can be stuck; the lower left keyhole The adjustment method of sheet 12 is the same as above; thereby the distance between keyholes on the hinge can be adjusted conveniently.

A hardware connector for convenient adjustment of keyhole spacing according to the present invention adopts a symmetrical frame-shaped hinge, and slidable keyhole pieces are arranged symmetrically in the longitudinal direction on the frame-shaped hinge. It is convenient to adjust the distance between the two keyholes on the hinge and easy to install; it has the advantages of simple structure and convenient operation, which can improve work efficiency and speed up construction, and the hinge adopts a frame shape, which can reduce material cost.

The above is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
