Embodiment Construction

[0011] A new type of welded detachable hinge, which consists of an upper leaf 1 and a lower leaf 2, the lower leaf 2 is interference fit with the mandrel 3, the two leaves are welded together with the end cover 4, the upper leaf 1 and the There are two steel wear-resistant gaskets 5 between the lower sheets 2. The upper sheet 2 is inserted into the shaft core 3 of the lower sheet 1 and can be flexibly rotated to complete the installation. At the same time, the upper and lower sheets can be quickly exchange.

Abstract

The invention relates to a novel welding detachable hinge. The hinge consists of an upper hinge piece and a lower hinge piece, wherein the lower hinge piece and a mandrel are integrated into a whole part; the upper hinge piece and an end cover are welded into a whole part; two rigid wear-resistant gaskets are arranged between the upper hinge piece and the lower hinge piece; the upper hinge piece is sleeved with a shaft core of the lower hinge piece and can rotate flexibly. The novel detachable hinge has a simple structure, the upper hinge piece and the lower hinge piece can be rapidly replacedwith each other, assembly and disassembly are convenient, time and labor are saved, the cost is greatly saved, and a door and a window can be directly disassembled without disassembling the hinge under an emergency. The welding detachable hinge is applicable to fireproof doors and windows under an emergency, and therefore the production of an automatic production line is facilitated.

Description

technical field [0001] The invention relates to a connecting piece between a door and window and a door and window frame. The end cover of the new type of welded detachable hinge is an internal welding type, which can be quickly fastened without falling off, fast in manufacture, saves in manufacturing cost, and is safe and firm. Two pads are added between the two leaves. The sheet reduces the friction between the two sheets. Background technique [0002] At present, the hinges on the market are basically assembled by two-tooth leaf, three-tooth leaf, mandrel, and end cover. After assembling the two-tooth leaf and the three-tooth leaf, string the mandrel into the common pipe. , the end caps are inserted into both sides of the tube through interference fit. This kind of hinge end cover is easy to fall off, wears seriously, and is troublesome to install. Contents of the invention [0003] Aiming at the defects of the existing hinge design, the present invention invents a ne...
