Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Referring to fig. 1 to 3, the present embodiment provides an opening and closing device for a fire window, including a sliding rail assembly 1 and a driving assembly 2, specifically, the sliding rail assembly 1 includes a sliding rail 11 fastened to a window frame, a sliding block 12 sliding back and forth along a length direction of the sliding rail 11, and a locking mechanism 13 disposed in the sliding block 12; the driving assembly 2 comprises an energy storage assembly used for automatically closing the window sash after the locking mechanism 13 is unlocked, and a connecting rod 21 meshed with the driving end of the energy storage assembly, and the connecting rod 21 is pivoted with the sliding block 12.

More specifically, the locking mechanism 13 in this embodiment includes a mercury glass ball 131, a rocker 132 abutting against the mercury glass ball 131, and a damping block 133 disposed at an end of the rocker 132 away from the mercury glass ball 131; preferably, in this embodiment, a wedge 134 is disposed between the mercury glass bulb 131 and the rocker 132, the wedge 134 is slidably connected to the slider 12, one end of the wedge 134 is provided with a groove abutting against the mercury glass bulb 131, and the other end of the wedge 134 is provided with an inclined surface for supporting the rocker 132 in a horizontal arrangement. In addition, a long groove 121 is formed on the upper surface of the slider 12 along the length direction, and the seesaw 132 is pivotally connected to two opposite sidewalls of the long groove 121.

By adopting the above structural design, under the abutting action of the mercury glass ball 131, the wedge 134 is provided with one end of the inclined plane in the initial state, so as to support one end of the rocker 132, and then the damping block 133 arranged at the other end of the rocker 132 abuts against the inner bottom surface of the long groove 121, so as to limit the opening and closing angle of the window sash.

Further, in order to adjust the resistance of the damping block 133 conveniently, in this embodiment, an adjusting screw 135 is vertically disposed at one end of the rocker 132 away from the mercury glass ball 131, and the damping block 133 located between the rocker 132 and the inner bottom surface of the long groove 121 is matched with the adjusting screw 135. Therefore, the resistance of the damping block 133 is adjusted to a reasonable range by the pressing of the adjusting screw 135 to the damping block 133.

Furthermore, preferably, the energy storage assembly in this embodiment includes a housing fastened to the window sash, a spring disposed in a cavity of the housing, and a rack 22 pressed at one end of the spring, and a slot facilitating engagement between the rack 22 and the connecting rod 21 is formed in a side wall of the housing. Furthermore, in order to facilitate the height of the casing along the window sash frame, the two ends of the casing are respectively provided with a fixing seat 23 convenient for fastening with a window sash.

In addition, in this embodiment, one end of the slider 12 close to the damping block 133 is pivotally connected to the connecting rod 21, one end of the connecting rod 21 pivotally connected to the slider 12 is bent, and one end of the connecting rod 21 pivotally connected to the fixing seat 23 is provided with a gear tooth for engaging with the rack 22. Further, in order to enable the end of the link 21 provided with the gear teeth to stably and reliably engage with the rack 22, it is preferable that an extension wall 231 extends out of the fixing seat 23 near the end of the rack 22, the extension wall 231 is located at one side of the slot, and the extension wall 231 is pivoted with the end of the link 21 provided with the gear teeth.

By adopting the opening and closing device with the structural design, after the window sash is opened at a certain angle, the spring in the shell is compressed, the locking mechanism 13 in the sliding block 12 limits the window sash to a preset opening angle, and then when a fire disaster happens, the mercury glass ball 131 is heated to reach a preset temperature and then automatically bursts, at the moment, the locking mechanism 13 is automatically unlocked, the resistance of the damping block 133 is reduced or fails, so that the elastic force of the spring is released, and finally the window sash and the window frame are automatically closed.

The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
