Cabinet double-door flat iron lock rod heaven and earth lock catch and assembling method

Abstract

The invention relates to a cabinet double-door flat iron lock rod heaven and earth lock catch and an assembling method. The heaven and earth lock catch comprises a base body, the cross section of thebase body is of a long kidney-shaped structure, and a positioning table is integrally arranged above the base body; a square groove is formed in one side face of the base body, and the base body, thesquare groove and the positioning table are symmetrically arranged with respect to the first symmetrical face of the base body; the upper surface of the positioning table is a first positioning face,a concave table is arranged on one side of the first positioning face, a screw hole is formed in the symmetrical center of the concave table, the screw hole extends into the base body and stops at thefirst groove side face of the square groove, and two cylindrical pins protruding out of the first positioning face are symmetrically arranged at the positions, on the two sides of the screw hole, ofthe concave table; and the central longitudinal section of the concave table is a second symmetrical surface which forms an offset distance with the first symmetrical surface, and the screw hole and the two cylindrical pins are symmetrically arranged by taking the second symmetrical surface as the center. According to the cabinet double-door flat iron lock rod heaven and earth lock catch, the original two accessories of a top lock catch and a bottom lock catch are simplified into the one-piece heaven and earth lock catch in the structure, and the heaven and earth lock catch is of a rotary symmetrical structure, so that the types of the accessories can be reduced, and two-piece functions are realized by the one-piece heaven and earth lock catch.

Description

technical field [0001] The invention relates to the technical field of cabinet accessories, in particular to a flat iron lock rod heaven and earth lock and an assembly method for a double door of a cabinet. Background technique [0002] In the existing production technology, in the production process of the cabinet, the top lock, the top lock and the door stop are usually designed together, so that when they are installed on the top and bottom frames of the cabinet, they must be divided into two parts to achieve flatness. The iron lock lever locks the left and right door panels on the top and bottom frames in turn. In a double-door cabinet, the upper and lower doorstops have a complex multi-functional shape structure. Although they seem to have the same structure, they must be divided into two parts. Two sets of molds must be opened. When assembling, it is necessary to distinguish between upper, lower, left, and right, and to ensure the airtightness after assembly. , result...
