Abstract

The invention discloses a novel hidden spring hinge. The novel hidden spring hinge comprises a hinge body and a driving part for driving the hinge body to be closed. The hinge body comprises a frame connecting piece, a sash connecting piece, a first connecting rod and a second connecting rod; a first sliding groove is formed in the frame connecting piece, a second sliding groove is formed in the sash connecting piece, and one end of the first connecting rod is connected with the frame connecting piece in a pivoted mode; meanwhile, the other end of the first connecting rod is in sliding fit with the second sliding groove, one end of the second connecting rod is simultaneously connected with the sash connecting piece and the first connecting rod in a pivoted mode, and other end of the secondconnecting rod is in sliding fit with the first sliding groove. The driving part comprises a sleeve, an upper ratchet wheel, a lower ratchet wheel, a torsion spring and a rotating shaft, wherein theupper ratchet wheel, the lower ratchet wheel, the torsion spring and the rotating shaft are arranged in the sleeve from top to bottom in sequence, the upper end and the lower end of the torsion springare correspondingly and fixedly connected with the lower ratchet wheel and the rotating shaft, and the upper ratchet wheel is fixedly connected with the sleeve.

Description

technical field [0001] The invention relates to the technical field of architectural hardware, in particular to a novel hidden spring hinge. Background technique [0002] Most of the hinges in the field of building doors, windows and fireproof windows in the market are exposed installations. As the market continues to change, in order to pursue the transparency, beauty and atmosphere of the window sashes, architects generally require that the hardware of the window sashes should not be exposed, and the hinges should have a high load-bearing capacity. The hidden hinges currently on the market require the main components to be made of steel castings in order to achieve fire resistance, which has high cost, poor machining accuracy, insufficient power and inconvenient installation. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a novel hidden spring hinge with a novel structure, easy installa...
