[0019] The utility model will be described in detail below in combination with the drawings and examples.

[0020] Quick-release fire sprinkler, such as Figure 1 And Figure 2As shown, including threaded sleeve 1 and connecting seat, connecting seat includes rotating seat 2 and base 3 fixedly connected with threaded sleeve 1, base 3 is provided with threaded hole 4, rotating seat 2 is provided with circular table 5 threaded in threaded hole 4, embedding groove 6 is arranged on the side wall of base 3, rotating seat 2 is rotatably connected with turnover buckle 7 for being clamped in embedding groove 6, sealing element 8 is arranged at the connecting place of base 3 and rotating seat 2, when it is necessary to replace the heat-sensitive glass tube, the operator can pick out turnover buckle 7 from embedding groove 6, so that turnover buckle 7 no longer limits the rotation of rotating seat 2, rotating seat 2 and base 3 can be separated by screwing rotating seat 2 from base 3, the operator can replace the heat-sensitive glass tube on the special tool with the broken heat-sensitive glass tube of rotating seat 2, compared with the existing fire sprinkler head which needs to overcome the friction between the raw material belt and threaded sleeve 1 to disassemble, this way is more convenient, and the replacement speed of the heat-sensitive glass tube can be improved, the setting of turnover buckle 7, when turnover buckle 7 is embedded in embedding groove 6, base 3 and rotating seat 2 are difficult to relatively rotate, which is beneficial to the operator to threadedly connect threaded sleeve 1 on the fire water pipe, the rotation direction of the thread on threaded sleeve 1 is opposite to that of the thread on circular table 5, this setting makes the operator not relatively rotate threaded sleeve 1 with the fire water pipe when screwing rotating seat 2, which is beneficial to ensure the connection sealing performance of threaded sleeve 1 and the fire water pipe.

[0021] As Figure 2 and Figure 3As shown, the bottom wall of the threaded hole 4 is provided with a first annular groove 9, the top surface of the circular table 5 is provided with a second annular groove 10 concentrically arranged with the first annular groove 9, one end of the sealing element 8 is fixedly installed in the second annular groove 10 by glue, and the other end of the sealing element 8 is embedded in the first annular groove 9. When the circular table 5 is in contact with the bottom wall of the threaded hole 4, the gap at the contact position can be better closed by the sealing element 8, thereby improving the sealing performance of the rotating seat 2 when installed on the base 3, preventing the water in the fire hose from leaking out, the sealing element 8 is a rubber ring, the width of the second annular groove 10 is smaller than the width of the first annular groove 9, the rubber ring has good plasticity, and the sealing element 8 made of this material can better guarantee its sealing performance. The second annular groove 10 is wider than the first annular groove 9, so that the width of the second annular groove 10 is greater than the thickness of the sealing element 8. When the operator screws the rotating seat 2 on the base 3, the above-mentioned arrangement is more conducive to embedding the sealing element 8 in the first annular groove 9. The height of the sealing element 8 is greater than the sum of the depth of the first annular groove 9 and the second annular groove 10. When the non-fixed end of the sealing element 8 is in contact with the inner wall of the first annular groove 9, it can deform to a certain extent, which can increase the contact area between the sealing element 8 and the inner wall of the first annular groove 9, thereby guaranteeing the sealing performance of the sealing element 8 on the rotating seat 2 and the base 3. The circular table 5 is also provided with a third annular groove 11 concentrically arranged with the second annular groove 10. The small diameter of the third annular groove 11 is greater than the large diameter of the second annular groove 10. The sealing gasket 12 is installed in the third annular groove 11. When the operator screws the rotating seat 2 on the base 3, the sealing gasket 12 is in contact with the bottom wall of the threaded hole 4, thereby improving the air tightness between the rotating seat 2 and the base 3 and guaranteeing the sealing performance between the rotating seat 2 and the base 3. When water enters the gap between the rotating seat 2 and the base 3, the air originally present between the rotating seat 2 and the base 3 cannot be discharged due to the presence of the sealing gasket 12. This part of the air can maintain the shape of the sealing element 8, so that the water is not easy to push open the sealing element 8, thereby further guaranteeing the sealing performance between the rotating seat 2 and the base 3.
