Active fireproof window positioning release system manufacturing method

Date:2017-10-31 Author:we Click:

At present, most domestic fireproof window products are fixed and manually closed. This kind of fireproof window is difficult to meet the national standard. The movable fireproof window must be blown by the temperature sensing element (such as the temperature glass ball and the metal temperature sense). The film, electronic temperature, etc.) triggers the automatic closing requirement, especially for the exterior windows of most residential and office buildings. The prior art movable fire window cannot achieve multi-angle positioning, convenient manual opening and closing, and reaching the set fire temperature state. The function of automatic shutdown is not conducive to fire safety.

   SUMMARY OF THE INVENTION

 It is an object of the present invention to provide a mobile fire window positioning and release system that overcomes the above-discussed deficiencies of the prior art. The purpose of the utility model is to realize a movable fire window positioning and releasing system, comprising a positioning support rod and a releasing device, wherein a front end of the positioning support rod is hinged with a fixing bracket, and the fixing bracket is fixed by a fixing screw and a movable type. The fireproof window of the fireproof window is fixedly connected; the middle of the positioning support rod is provided with a card slot, and the card slot is movably connected with the bottom end of the fireproof window frame of the movable fireproof window by the positioning screw, the top of the fireproof window and the fireproof window frame An automatic door closer is connected between the top ends of the positioning support rod; a release device is connected to the rear end side of the positioning support rod, and the release device is fixedly connected to the bottom inner wall of the fireproof window frame through the mounting plate. The release device comprises a positioning sleeve, the left end of the positioning sleeve is open, the positioning sleeve is provided with a cylindrical spiral compression spring, the left end of the cylindrical spiral compression spring is connected with a pressing block, the middle part of the pressing block is connected with the adjusting screw, and the adjusting screw is The rear end of the positioning support rod is fixedly connected, and the top end of the pressing block is fixedly connected to the top end of the positioning sleeve through the temperature sensing glass ball. The utility model has the advantages of simple structure, reasonable design, high safety, convenient opening, and is not restricted by the installation conditions, and is easy to install and realize.    

The present invention will be further described in detail below with reference to the accompanying drawings. 1 is a schematic structural view of a movable fire window positioning and releasing system according to an embodiment of the present invention; FIG. 2 is a partial enlarged view of FIG. 1A; FIG. 3 is a positioning release system according to an embodiment of the present invention; Structural cross-sectional view.

Detailed description   

[0014] As shown in FIG. 1-2, a movable fireproof window positioning release system according to an embodiment of the present invention includes a positioning support rod I and a release device 2, and the positioning support rod I The front end is hinged with a fixing bracket 3, and the fixing bracket 3 is fixedly connected with the fireproof window 4 of the movable fireproof window by a fixing screw, and the top end of the fireproof window 4 is connected with the top end of the fireproof window frame 7 of the movable fireproof window. The automatic door closer 14 is provided with a card slot 5 in the middle of the positioning support bar I, and the card slot 5 is movably connected to the bottom end of the fire window frame 7 through the positioning screw 6; the rear end side of the positioning support bar I is connected and released The device 2, the release device 2 is fixedly connected to the bottom inner wall of the fire sash 7 by means of a mounting plate 8. As shown in FIG. 3, the release device 2 includes a positioning sleeve 9. The left end of the positioning sleeve 9 has an opening shape, and the positioning sleeve 9 is provided with a cylindrical spiral compression spring 10, and the left end of the cylindrical spiral compression spring 10 is connected with a pressing block 11 The adjusting screw 12 is connected to the center of the pressing block 11, and the adjusting screw 12 is fixedly connected to the rear end of the positioning support rod 1. The top end of the pressing block 11 is fixedly connected to the top end of the positioning sleeve 9 through the temperature sensing glass ball 13. In specific use, the movable fire window can achieve the multi-angle positioning function through the mutual cooperation between the card slot 5 and the positioning screw 6. When a fire occurs on site, the temperature-sensitive glass ball 13 on the release device 2 will reach its own fire temperature...
