hinge

Abstract

The invention relates to a hinge. According to the hinge, a connecting rod is rotationally connected with a rotating shaft, a fixed hole is formed in the connecting rod, a first limiting hole and a second limiting hole are formed in the rotating shaft, a first guide groove extending out from the first limiting hole and a second guide groove extending out from the second limiting hole are formed, alimiting piece is arranged and comprises a limiting part, the limiting part has a first width S1 in the first direction and has a second width S2 in the second direction, the S1 is larger than the S2, the S2 is not larger than the width of the first guide groove and the width of the second guide groove, the S1 is larger than the width of the first guide groove and the width of the second guide groove, the limiting part can be contained into the first limiting hole, when the limiting part is rotated to the first direction which is matched with the extending direction of the first guide groove,the limiting part is unlocked with the first limiting hole or the second limiting hole, and therefore the limiting piece can slide into the first guide groove and the second guide groove and can slide into the second limiting hole, the limiting part is rotated to enable the limiting piece to be locked to the second limiting hole, and left-and-right exchange of the hinge is achieved.

Description

technical field [0001] The invention relates to the technical field of door and window hardware accessories, in particular to hinges. Background technique [0002] In the installation structure of doors and windows, the corner hinges are commonly used to connect the sash and the window frame. However, most of the commonly used corner hinges are rivet rigid connection structures. Once installed, the left and right interchangeability of the corner hinges cannot be realized. During use, if you need to adjust the left and right opening of the window or if the customer makes a mistake in the left and right hinges when placing an order, the product cannot be used, and the corresponding hinges need to be re-customized, which will seriously affect the construction progress and cause hinge failures. waste. Contents of the invention [0003] Based on this, it is necessary to provide a hinge for the current problem that the corner hinge cannot be interchanged between left and right....
