[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This retractable fire sprinkler head, when extending or retracting, uses a motor to drive a telescopic rod to extend or retract the fixed block, moving block, and limiting shell. The extension or retraction distance of the telescopic rod does not exceed the length of the limiting shell, thus limiting the limiting shell and enabling the fire sprinkler head to automatically extend or retract in the event of a fire. The power output shaft of a second motor inside the fixed shell drives a rotating rod to rotate, causing the sprinkler baffle to rotate, thereby increasing the spray range of the fire sprinkler head and solving the problem of automatic extension and retraction and the range of the fire sprinkler head.

[0013] 2. The retractable fire sprinkler head is protected by an airbag around the heat-sensitive glass column. When the equipment is in normal placement, the airbag protects it from damage caused by personnel touching it, which could lead to accidental spraying. When the equipment is retracting, the airbag prevents objects below from impacting the sprinkler baffle and damaging it, thus preventing the equipment from spraying water in a wide area. The airbag provides protection for the equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 A retractable fire sprinkler head includes a square shell 1. A motor 3 is fixedly mounted on the top inner wall of the square shell 1. A connecting shell 4 is fixedly mounted on the bottom of the square shell 1. A water inlet pipe 2 is fixedly mounted on the outer wall of the square shell 1. A telescopic rod 5 is fixedly mounted on the power output shaft of the motor 3. A movable block 7 is provided at the bottom of the connecting shell 4. A limiting shell 8 is fixedly mounted on the top of the movable block 7, located on the inner wall of the connecting shell 4. A fixing block 6 is fixedly mounted on the outer edge of the movable block 7. A limiting block 16 is provided in the inner cavity of the movable block 7. A thermal glass column 9 is fixedly mounted at the bottom of the 16. An airbag 17 is provided on the outer wall of the thermal glass column 9. A base 15 is fixedly mounted at the bottom of the thermal glass column 9. A fixing strip 10 is fixedly mounted on the outer wall of the base 15. A fixing shell 12 is fixedly mounted at the bottom of the base 15. A motor 13 is fixedly mounted on the top inner wall of the fixing shell 12. A rotating rod 14 is fixedly mounted on the power output shaft of the motor 13. A water spray baffle 11 is fixedly mounted on the outer edge of the rotating rod 14. An airbag 18 is fixedly mounted at the bottom of the fixing shell 12.

[0022] It should be noted that when the equipment extends or retracts, the power output shaft of motor 13 drives the telescopic rod 5, which in turn drives the fixed block 6, the moving block 7, and the limiting shell 8 to extend or retract, achieving an electric extension or retraction effect. Through the fixed shell 12 at the bottom of the base 15, the power output shaft of motor 213 drives the rotating rod 14 to rotate, which in turn drives the water spray baffle 11 to rotate, thus increasing the spray range of the fire sprinkler head during the water spraying process. The airbag 17 protects the heat-sensitive glass column 9, preventing accidental spraying due to collisions or friction from personnel under normal conditions. The airbag 218 fixedly mounted at the bottom of the fixed shell 12 prevents objects below from colliding with the water spray baffle 11 and damaging it during the extension or retraction of the equipment, thereby limiting the spray range and achieving the protection function of the water spray baffle 11.

[0023] In a preferred embodiment, the threaded pipe at the end of the water inlet pipe 2 is threadedly connected to the water pipe, and the fixing block 6 is fixedly assembled with the motor 3 via the telescopic rod 5.

[0024] It should be noted that the water pipe is connected to the equipment by a threaded pipe at the end of the inlet pipe 2, so that the water pipe can output water to the equipment.

[0025] In a preferred embodiment, the base 15 is fixedly assembled with the movable block 7 by a fixing strip 10, and a glass ball is placed in the inner cavity of the thermosensitive glass column 9.

[0026] It should be noted that when the air reaches a temperature of 68°C through the glass beads inside the thermosensitive glass column 9, it expands, which puts pressure on the outside glass, causing the glass to crack and thus releasing water.

[0027] In a preferred embodiment, the telescopic length of the telescopic rod 5 is less than the length of the limiting shell 8.

[0028] It should be noted that the telescopic length of the telescopic rod 5 is less than the length of the limiting shell 8, so that the limiting shell 8 is always inside the cavity of the connecting shell 4.

[0029] In a preferred embodiment, the threaded tube at the end of the thermosensitive glass column 9 is threadedly connected to the top of the base 15.

[0030] It should be noted that the thermal glass column 9 is fixed by connecting the threaded tube at the end of the thermal glass column 9 to the base 15 via a threaded connection.

[0031] In a preferred embodiment, the maximum temperature of the thermosensitive glass column 9 is limited to 68°C, and there are two sets of fixing strips 10, which are symmetrically distributed on the outer wall of the base 15.

[0032] It should be noted that the thermal glass column 9 is shattered when the temperature exceeds 68°C, and the fragments of the thermal glass column 9 collide with the airbag 17, causing the airbag 17 to be damaged as well, and allowing water to flow out.

[0033] Working principle: The water pipe is threadedly connected to the water pipe at the end of the inlet pipe 2, thus fixing it to the water pipe. When the equipment extends or retracts, the power output shaft of motor 13 drives the telescopic rod 5, which in turn drives the fixed block 6, the moving block 7, and the limiting shell 8 to extend or retract, achieving an electric telescopic effect. Through the fixed shell 12 at the bottom of the base 15, the power output shaft of motor 213 drives the rotating rod 14 to rotate, which in turn drives the sprinkler baffle 11 to rotate, thus increasing the spray range of the fire sprinkler head during the spraying process. 7. The thermal glass column 9 is protected to prevent accidental spraying due to collisions and friction by personnel under normal conditions. The airbag 18 fixedly mounted at the bottom of the fixed shell 12 prevents objects below from colliding with and damaging the water spray baffle 11 when the equipment is extended or retracted, thus limiting the spraying range and protecting the water spray baffle 11. The thermal glass column 9 is shattered by high temperature, and the fragments of the thermal glass column 9 collide with the airbag 17, damaging the airbag 17 as well, and allowing water to flow out.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
