Window closing device and fireproof window containing window closing device

Abstract

The invention relates to a window closing device. The window closing device comprises a first sliding groove arranged on a cross bar at the upper portion of a window opening fan and a sliding block cooperating with the first sliding groove. The sliding block is hinged to a sliding rod through a first tightness adjusting mechanism; a positioning unit is arranged in the first sliding groove; the positioning unit is connected with a second tightness adjusting mechanism; the second tightness adjusting mechanism is connected with a power mechanism through a connecting rod. The power mechanism comprises a fixing unit and a sliding unit; an elastic unit and a thermal sensing element are arranged between the fixing unit and the sliding unit; the sliding rod is connected with a closer arranged on a window frame. The invention also provides a fireproof window containing the window closing device. According to the window closing device, by arranging the first sliding groove and the sliding block cooperated with each other and the thermal sensing element, when the thermal sensing element is heated and broken, the sliding block drives the sliding rod to carry out the linkage, the sliding rod and the closer are cooperated with each other, and the window is opened and closed automatically in the case of fire; the window closing device is matched with the window closing device to realize real fireproof function. The window closing device is exquisite in structure design, does not affect the installation of other devices after the window closing device is installed, is relatively beautiful and strong in practicability.

Description

technical field [0001] The invention relates to the construction field, in particular to a window closer and a fireproof window including the window closer. Background technique [0002] Most of the existing fire windows in the market are made of steel, wood or steel-wood composite materials, and there are more fixed types and less movable types in terms of function. Since GB50016-2014 "Code for Fire Protection Design of Buildings" was promulgated and implemented on May 1, 2015, for residential buildings with a building height greater than 54m, each household should have one room that meets the following requirements: 1) It should be installed against the outer wall, and should be Set openable outer windows; 2) The fire resistance rating of the inner and outer walls should not be lower than 1.00h, the door of this room should be a Class B fire door, and the fire integrity of the outer windows should not be lower than 1.00h. [0003] Chinese patent CN 203796048U "An Automati...
