The utility model provides an automatic window closer for a fireproof window.
In the embodiment of the utility model, the automatic fire window closer comprises an elongated shell 1, a movable seat 2, a window closer main body 3, a connecting rod 4, a mounting seat 5, a locking driving piece 6, a temperature sensing glass ball 7 and a release spring 8.
The strip-shaped shell 1 is arranged in the upper cross beam 100 of the window frame, the bottom wall of the strip-shaped shell is provided with a guide chute 11 extending along the length direction of the strip-shaped shell, the guide chute 11 faces downwards, and the upper cross beam 100 of the window frame is used for shading sun and shielding rain, so that the service life of the strip-shaped shell is prolonged.
The movable seat 2 is slidably mounted in the guide chute 11, and a hook groove 21 is formed in a portion of the movable seat 2 located in the elongated housing 1, and the hook groove 21 faces downward.
The window closer body 3 is mounted in the cross beam 200 of the window sash frame, and the rotating shaft 31 of the window closer body 3 extends out of the cross beam 200 of the window sash frame. The window closer body 3 itself has waterproofness, and only the rotation shaft 31 protrudes out of the cross beam 200 of the window sash frame, so that the internal parts can be prevented from being sunburned and drenched. It should be noted that, as is well known to those skilled in the art, the rotation shaft 31 of the window closer body 3 may generate a force tending to swing in a closing direction on the window sash after the window sash is opened, and the rotation shaft 31 may drive the window sash to swing when the resistance is smaller than the force tending, so that detailed description of the specific structure and working principle thereof will not be repeated.

Specifically, more than half of the rollers 511 are engaged into the hooking grooves 21, so as to prevent the movable seat 2 from being separated from the rollers 511 under the action of external force. But cannot be blocked too much, so that the roller 511 cannot be separated from the hooking groove 21 after the temperature sensing glass ball 7 is broken, and the window sash cannot be automatically closed.
In the embodiment of the utility model, one side of the locking driving piece 6 far away from the opening position is provided with the bending part 61 extending upwards, the side wall of the bending part 61 facing the opening position is elastically propped against the movable seat 2 through the release spring 8, one end of the temperature sensing glass ball 7 facing the opening position is propped against the side wall of the bending part 61 facing away from the opening position, one end of the temperature sensing glass ball 7 facing away from the opening position is propped against the positioning block 12 fixedly arranged in the strip-shaped shell 1, and after the temperature sensing glass ball 7 is broken, the release spring 8 pushes the locking driving piece 6 to move towards the positioning block 12 so as to separate the locking hook body 51 from the hook groove 21.
Specifically, the first clamping groove 611 is formed at the position of the bending portion 61 opposite to the temperature sensing glass ball 7, so that the temperature sensing glass ball 7 is clamped and positioned towards one end of the opening position, and the second clamping groove 121 is formed at the position of the positioning block 12 opposite to the temperature sensing glass ball 7, so that the temperature sensing glass ball 7 is clamped and positioned away from one end of the opening position, and the installation stability of the temperature sensing glass ball 7 is ensured.
Further, the locking driving member 6 is further provided with a resilient piece 9 extending toward the closing position, the body of the resilient piece 9 is curled from the end to an upwardly arched supporting ring 91, when the window sash is in a normally open state, the supporting ring 91 abuts against the roller 511 to support the roller 511, and when the temperature sensing glass ball 7 is broken, the supporting ring 91 moves along with the locking driving member 6 and is separated from the roller 511.
