Detailed Description

The claimed invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, a fire window system to which the fire-proof temperature-controlled spacer of the present embodiment is applied is shown, and includes a window sash 4, a window frame 5, a fire-proof temperature-controlled spacer, and a self-closing hinge 6 for achieving self-closing of the window sash 4.

Referring to fig. 3 and 4, the fireproof temperature-controlled spacer in this embodiment includes a guide rail 1 fixedly connected to a window sash 4, a sliding assembly slidably connected to the guide rail 1, and a stay bar 3 having two ends pivotally connected to the sliding assembly and a window frame 5, respectively.

The surface of the guide rail 1 is formed with a limiting protrusion 11 and a releasing protrusion 12 for limiting the sliding assembly, and in this embodiment, the number of the limiting protrusions 11 is three, which correspond to the closed, half-open and full-open states of the window sash 4.

The sliding assembly comprises a sliding seat 21, a positioning assembly 22 connected to the sliding seat 21 and matched with the limiting protrusion 11 for limiting, and a temperature control element 23 arranged between the positioning assembly 22 and the sliding seat 21. In this embodiment, the positioning assembly 22 includes a positioning buckle 221 engaged with the limiting protrusion 11 and a mounting part 222 for mounting the positioning buckle 221, a space for the positioning buckle 221 to swing is reserved in the mounting part 222, and an elastic member 223 for driving the positioning buckle 221 to abut against the surface of the guide rail 1 is disposed in the mounting part 222, in this embodiment, the elastic member 223 is a spring piece.

The sliding seat 21 is provided with a buckling groove 211, the positioning assembly 22 is provided with a buckling part 224, two ends of the temperature control element 23 respectively abut against the sliding seat 21 and the positioning assembly 22 to keep the buckling groove 211 and the buckling part 224 buckled with each other, specifically, the sliding seat 21 is provided with the buckling groove 211, the positioning assembly 22 is provided with a buckling part 224 matched with the buckling part 224, the sliding seat 21 is in threaded connection with a jacking screw 24 jacking with the temperature control element 23, two ends of the temperature control element 23 respectively abut against the sliding seat 21 and the positioning assembly 22 to keep the buckling groove 211 and the buckling part 224 buckled with each other, and when the temperature control element 23 is damaged, the positioning assembly 22 is separated from the sliding seat 21.

The working principle of the fireproof temperature-controlled support in the embodiment is as follows:

referring to fig. 5, when the window sash 4 is in the closed state, its sliding assembly is at the end of the guide rail 1 and its positioning catch 221 interferes with the stop protrusion 11 corresponding to the closed state, while its stay 3 is folded parallel to the guide rail 1.

Referring to fig. 6 and 8, when the window sash 4 is opened, the stay bar 3 drives the sliding assembly to slide along the guide rail 1, when the window sash 4 is opened to a half-open state, the positioning buckle 221 of the stay bar is abutted against the limiting protrusion 11 corresponding to the half-open state, and since the self-closing hinge 6 can provide a closing torque for the window sash 4, the window sash 4 cannot be opened naturally, and meanwhile, since the positioning buckle 221 is matched and positioned with the limiting protrusion 11, the window sash 4 is kept at the current position and cannot be closed.

Referring to fig. 7, when the window sash 4 is opened to a maximum angle, the positioning catch 221 interferes with the trip protrusion 12 and swings inward the mounting member 222 when the slide assembly slides to the end of the stroke. After the positioning buckle 221 swings into the mounting part 222 to a proper position, the height of the positioning buckle 221 is staggered with the limiting protrusion 11, and the positioning assembly 22 quickly slides over the limiting protrusion 11 under the action of the self-closing device, so that the limiting effect of the limiting protrusion 11 on the positioning buckle 221 is avoided, and the window sash 4 can be smoothly closed.

When the fire window encounters fire, the interference effect of the temperature control element 23 on the sliding seat 21 and the positioning assembly 22 disappears, the buckling connection between the buckling groove 211 and the buckling part 224 is cancelled, and the positioning assembly 22 falls off from the sliding seat 21 under the action of the self-closing hinge 6, at this time, the limiting protrusion 11 no longer generates a positioning effect on the sliding seat 21, and the sliding seat 21 can smoothly drive the window sash 4 to close under the drive of the self-closing hinge 6.
