Embodiment Construction

[0025] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] see Figure 1-4 As shown, a temperature-sensitive fireproof window closer is arranged between the window frame 100 and the sash 101, and includes a device body 1, a support arm 2 and a cylinder body 3. The device body 1 is arranged on the window frame 100, and the cylinder body 3 Set on the frame of the window sash 101, the two ends of the support arm 2 are rotatably connected with the device body 1 and the cylinder body 3 respectively. The slider 5 arranged in the guide rail 4 , the locking assembly 6 used to limit the sliding of the slider 5 relative to the guide rail 4 , and the support arm 2 is rotatably connected with the slider 5 . Here, the cylinder body 3 is used to provide rotational force for the window sash 101 , and when the locking assembly 6 is unlocked, the cylinder body 3 drives the window sash 101 to rotate to close th...

Abstract

The invention discloses a temperature-sensing fireproof window closer which comprises a closer body, a supporting arm and a cylinder body. The closer body comprises a guide rail, a slider and a locking assembly. The locking assembly comprises a limiting piece and a temperature-sensing glass column. A limiting hole is formed in the slider in the direction perpendicular to the bottom face of the slide rail. A limiting groove is formed in the side wall of the guide rail. The limiting piece comprises a piece body, a first limiting rod arranged on the piece body and used for penetrating through thelimiting hole in cooperation, and a second limiting rod arranged on the piece body and used for being clamped in the limiting groove in cooperation. According to the temperature-sensing fireproof window closer, by forming the limiting groove in the side wall of the guide rail, the limiting hole in the slider and the limiting piece for limiting in cooperation with the limiting groove and the limiting hole, the sliding of the slider can be effectively restrained, and the locking effect is good; meanwhile, by arranging the temperature-sensing glass column, an effective reaction can be given in time in a fire disaster, and fire spreading is prevented; the temperature-sensing fireproof window closer is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a temperature-sensitive fireproof window closer. Background technique [0002] Window closers, which are mainly used for various movable fire windows, solve the problem that the movable fire windows cannot realize ventilation and lighting because they are usually closed. Existing window closers are generally divided into two types, one is an electric window closer, and the other is a movable window closer controlled by a mechanical principle. Its main function is reflected in two aspects: on the one hand, it can open and position the fire windows in a limited way to improve the ventilation and lighting effects; on the other hand, when a fire occurs, it can automatically close the windows to prevent the circulation of air to control the spread of fire. [0003] However, most of the existing window closers are complex in structure, and cannot respond in time when a fire breaks out, and are prone to accidents and cause danger. ...
