Abstract

The invention discloses a temperature controlled type self-closing device for a fireproof door and window. The temperature controlled type self-closing device comprises a connecting rod, a guiding sliding groove, a sliding block, a limiting block, a positioning block, a temperature sensing part and a power assembly, the connecting rod is connected with the sliding block in a pivoted mode, the sliding block is further slidably connected with the guiding sliding groove, the positioning block is fixedly connected to the lower side of the sliding block, an inserting groove is formed in the position, at the initial position of a sliding stroke of the sliding block, of the guiding sliding groove, the limiting block is connected to the lower side of the inserting groove in an inserted mode, the temperature sensing part is disposed between the limiting block and the positioning block, and the power assembly is used for driving the sliding block to slide along the guiding sliding groove and enabling the temperature sensing part to press the limiting block.

Description

technical field [0001] The invention relates to the technical field of fireproof door and window accessories, in particular to a temperature-controlled self-closing device for fireproof doors and windows. Background technique [0002] At present, most of the temperature-controlled automatic locking devices for fire-proof windows on the market are external and tension spring structures. When a fire occurs, the temperature-sensing element will burst after the temperature reaches the specified temperature, and the fire-proof windows will automatically close under the power of the locking device. The external automatic locking device is bulky, takes up a lot of space, has a complex structure, and has high production costs; the extension spring type locker has an unstable structure and insufficient fatigue strength of the extension spring, and the market competitiveness of these two methods is relatively weak. Contents of the invention [0003] The purpose of the present invent...
