Embodiment Construction

[0016] The present invention will be further described below in conjunction with the drawings and descriptions of the drawings.

[0017] A dovetail spherical movable lug, comprising an upper movable lug 1 and a lower movable lug 2, one side of the upper movable lug 1 is an inclined surface, and a dovetail penetrating up and down is arranged on one side of the inclined surface of the upper movable lug 1 Groove 3; one side of the lower movable lug 2 is also an inclined surface, and the inclined surface of the lower movable lug 2 is mirror-symmetrical to the inclined surface of the upper movable lug 1. The convex dovetail 4 with the same inclination angle on the inclined surface of the ear 2, and the chute 5 with the same inclination angle as the dovetail 4 is arranged in the dovetail 4.

[0018] The dovetail 4 of the lower movable lug 2 is placed in the dovetail groove 3 of the upper movable lug 1, and a positioning pin 6 is fixed on the upper movable lug 1, and the dovetail pin...

Abstract

The invention relates to a dovetail spherical movable lifting lug. The dovetail spherical movable lifting lug comprises an upper movable lifting lug and a lower movable lifting lug; one side of the upper movable lifting lug is an inclined face, a vertically through dovetail groove is formed in one side of the inclined face of the upper movable lifting lug, one side of the lower movable lifting lugis also an inclined face, the inclined face of the lower movable lifting lug and the inclined face of the upper movable lifting lug are in mirror symmetry, a convex dovetail consistent with the inclined angle of the inclined face of the lower movable lifting lug is arranged on one side of the inclined face of the lower movable lifting lug, and a sliding groove consistent with the inclined angle of the dovetail is formed in the dovetail. The dovetail of the lower movable lifting lug is arranged in the dovetail groove of the upper movable lifting lug, a positioning pin is fixed to the upper movable lifting lug, and the positioning pin penetrates the dovetail groove and the sliding groove in the dovetail. The upper movable lifting lug can slide in the range defined by the positioning pin andthe sliding groove along the convex dovetail of the lower movable lifting lug. Through the lifting lug, the problem that most steel furniture, box cabinets and door folding sides are not thorough, the surface is not flat, and the size is lack of standardization is solved.

Description

technical field [0001] The invention relates to a dovetail spherical movable lug, which belongs to the technical field of movable lug design. Background technique [0002] When folding steel furniture, cabinets, doors, etc., when there is no pressing object at the edge to be folded, there will be incomplete folding, uneven surface, and irregular size during the folding. problem. Therefore, it is necessary to place a pressing object at the edge to be folded, so as to facilitate the force during the edge fold. But not all of the hemming places can conveniently place the pressing object, and the placing of the pressing object is often a whole piece, and it is impossible to squeeze the back side of the hemming to be folded, thereby affecting the effect of the hemming. Contents of the invention [0003] The object of the present invention is to provide a dovetail ball-type movable lifting lug with reasonable structure, easy manufacture and convenient use, aiming at the disadv...
