Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides a novel temperature-control manual window closing device, which comprises a manual control pawl 1, a permanent magnet 2, a compression spring 3, a pawl control rod 4, a guide device 5, a temperature sensing device 6, a fixing device 7, a fixed bottom plate 8, a ratchet wheel 9, an extension spring 10 and an elastic return device 11; the fixed bottom plate 8 is fixed on the elastic return device 11, and the guide device 5 is arranged on the fixed bottom plate 8; the pawl control rod 4 is arranged on the guide device 5, one end of the temperature sensing device 6 is fixed on the guide device 5, the other end of the temperature sensing device 6 is fixed on the pawl control rod 4, and when the temperature sensing device 6 is broken, the pawl control rod 4 can move linearly on the guide device 5; a compression spring pushing part 12 is arranged at the front part of the pawl control rod 4, a compression spring limiting block 13 is arranged on the fixed bottom plate 8, and the compression spring 3 is arranged at the front part of the pawl control rod 4 and is positioned between the compression spring pushing part 12 and the compression spring limiting block 13; the front end of the pawl control rod 4 passes through the compression spring limiting block 13 and is connected with a handle of the manual control pawl 1; the ratchet wheel 9 is arranged on a rotating shaft of the elastic return device and can rotate along with the rotating shaft. The pawl portion of the manual pawl 1 and the ratchet wheel 9 are detachably engaged; one end of the extension spring 10 is connected to the pawl part of the manual control pawl 1, and the other end is fixed to the fixed bottom plate 8; when the temperature sensing device 6 is in a normal state, the compression spring 3 is in a compressed state; the permanent magnet 2 is arranged on a compression spring limiting block 13 of the fixed bottom plate and can magnetically adsorb a handle of the manual pawl 1.
The working principle of the device is as follows: when no fire hazard exists, the temperature sensing device provides supporting acting force for the pawl control rod, and at the moment, the compression spring is in a compression state under the combined action of the compression spring pushing part and the compression spring limiting block.
When the fire window is pushed away manually, the elastic return device 11 applies rotating power to the ratchet wheel 9, the ratchet wheel 9 generates acting force on the pawl part of the manual control pawl 1 under the action of external force, so that the pawl part temporarily leaves the ratchet wheel 9 until the external force pushing away the fire window manually disappears, and the front end of the manual control pawl 1 is re-engaged with the ratchet wheel under the action of the extension spring 10. Because the ratchet wheel and the pawl can only move in one direction, the ratchet wheel and the manual control pawl can be automatically positioned without external force after the hands are released, and the fire window can be stably in an opening state. As shown in fig. 1.
When the fire window needs to be manually closed, the handle of the manual control pawl is pulled rightwards until the handle is magnetically adsorbed to the permanent magnet, the pawl part of the manual control pawl moves leftwards (rotates clockwise), the extension spring is extended, and the acting force of the extension spring returning leftwards can be counteracted and overcome under the action of the permanent magnet. After the occluding force of the manual control pawl obtained by the ratchet wheel is lost, the elastic return device automatically returns to drive the fire window to automatically close. As shown in fig. 2.
When the fire window is in an open state, if a fire disaster occurs, the temperature sensing device is heated and broken, the supporting acting force on the pawl control rod disappears, the return acting force of the compression spring pushes the compression spring pushing part to move rightwards, so that the front end of the pawl control rod pulls the handle of the manual pawl rightwards, and the handle of the manual pawl is adsorbed on the permanent magnet. The pawl part of the manual control pawl moves leftwards and leaves the ratchet wheel, the elastic return device loses the fixing effect of the manual control pawl obtained by the ratchet wheel, and the elastic return device automatically returns to drive the fire window to automatically close. As shown in fig. 3.
In this embodiment, as shown in fig. 4. The front end of the pawl control rod 4 is provided with a groove 41, and the handle of the manual control pawl 1 is positioned in the groove 41. In case of fire, the recess exerts a force pulling to the right on the handle of the manual pawl 1.
In this embodiment, the compression spring pushing member 12 is a screw, the front portion of the pawl control rod 4 is provided with a vertical screw hole 43, and the screw 12 is vertically fixed in the vertical screw hole 43 and has a vertical length greater than the outer diameter of the compression spring 3.
In this embodiment, the top of the rear portion of the ratchet lever 4 is provided with an upward protrusion 44, the rear end of the guide 5 is provided with an upward fixing protrusion 14, and one end of the temperature sensing device 6 is connected to the upward protrusion 44 of the ratchet lever and the other end is connected to the upward fixing protrusion 14 of the guide.
In the present embodiment, the temperature sensing device 6 is a temperature sensing glass device.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
