Description

Two-dimensional adjusting hidden hinge

Technical Field

The utility model belongs to the technical field of door hinges, and particularly relates to a two-dimensional adjusting hidden hinge.

Background

The fire-fighting stone door has the functions of a common door and also meets the requirements of fire-resistant stability, integrity and heat insulation, because gaps exist between the edges of the fire-fighting door and the door frame, smoke dust is easy to pass through the fire-fighting door, in order to prevent excessive smoke dust from passing through the fire-fighting door, gaps between the fire-fighting doors must be small enough, the existing fire-fighting door must meet the requirements of small gaps and large opening angles while playing a fire-fighting function, and according to the unique technical requirements of the fire-fighting door, the hinge for the fire-fighting door also has the higher technical requirements and meets the requirements of strong bearing capacity and the like, however, the hinge in the prior art needs to be fixed by a fixed seat with a longer length, so that the closing and opening processes of the window sashes can be completed, and the movement track of the hinge is irregular, so that the force and the pushing track of a door closer or a window closer for closing the fire-fighting door or window can not close or close the window tightly when the fire-fighting door or window is in fire condition.

The Chinese patent publication number is: CN211008105U patent name: a hinge, hidden door and fire hydrant box, the hinge comprising: the first mounting plate is mounted on the door plate, and a first connecting boss is arranged on one surface of the first mounting plate, which faces away from the door plate; the first connecting boss is provided with a first groove; a plurality of second grooves are formed in one surface of the first mounting plate, which faces the door plate; the second mounting plate is mounted on the door frame, and a second connecting boss is arranged on one surface of the second mounting plate, which is away from the door frame; a plurality of third grooves are arranged on one surface of the second mounting plate facing the door frame, a plurality of fourth grooves are arranged on one surface of the second connecting boss facing the first connecting boss, the connecting arm assembly is connected between the first connecting boss and the connecting boss, a plurality of second grooves are arranged on the first mounting plate, a plurality of third grooves are arranged on the second mounting plate,

although the utility model has the advantages of it can satisfy the user demand of general condition, but its structure is very complicated, need process dodges the mouth to another needs to follow dodge mouthful in the installation and pass, not only greatly increased processing cost, but also improved the degree of difficulty of installation greatly, its third mounting flange and second connecting block adopt the stack processing simultaneously, have not only increased the degree of difficulty of processing, can also influence the normal action of linking arm moreover, use stationarity and reliability are relatively poor, so suitability and practicality are restricted.
