[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides an embodiment: a sprinkler for fire fighting, comprising:

[0026] A connecting pipe 1, the external thread of the connecting pipe 1 is connected to a nut 6, the bottom of the nut 6 is connected to a bracket 7, the other end of the bracket 7 is connected to a threaded barrel 8, the bottom of the threaded barrel 8 is connected to a water distribution plate 9, and the setting of the water distribution plate 9 can disperse the water source impacted by the falling water, thereby increasing the water source spraying area;

[0027] The thermosensitive glass ball 10 has a threaded column 11 connected to the bottom thereof, and the threaded column 11 is threadedly connected to the inside of the threaded tube 8. The thermosensitive glass ball 10 contains kerosene, ether and other solutions, wherein the action temperatures of various colors are: 68°C for red, 79°C for yellow, 93°C for green and 141°C for blue;

[0028] The support frame 3 is connected to the inner wall of the connecting tube 1, and a guide rod 4 is passed through the interior of the support frame 3. A plug 5 is connected to the bottom of the guide rod 4, and the plug 5 is sealed and plugged into the interior of the connecting tube 1. The plug 5 is connected and positioned by the sliding plug-in method, so that when it is used, it can effectively prevent the plug 5 from falling and being lost, thereby facilitating its subsequent use and improving the convenience of subsequent use of the device.

[0029] Furthermore, the outer wall of the connecting tube 1 is fixedly connected with a limiting ring 2, and the outer diameter of the limiting ring 2 is larger than the outer diameter of the connecting tube 1, and the lower surface of the limiting ring 2 abuts against the upper surface of the nut 6. The setting of the limiting ring 2 plays a role of limiting as well as separating.

[0030] Furthermore, the connecting pipe 1 is provided with a first external thread above the limiting ring 2, and the connecting pipe 1 is provided with a second external thread below the limiting ring 2, and the second external thread is connected to the nut 6, and the length of the first external thread is greater than that of the second external thread, so as to facilitate the distinction between the two.

[0031] Furthermore, the top of the guide rod 4 is in a step shape, the upper surface edge of the plug 5 is in an arc-shaped structure, and the top outer surface of the plug 5 is wrapped with a sealing sleeve. The setting of the sealing sleeve improves the sealing effect of the plug-in connection to avoid water leakage. At the same time, the setting of the arc-shaped structure on the top edge can divert the falling water source, so that the water source and the water distribution plate 9 collide with each other, ensuring the dispersion of the water source.

[0032] Furthermore, a positioning hole is provided at the center of the bottom of the plug 5 , and the top of the thermosensitive glass ball 10 abuts against the inside of the positioning hole of the plug 5 .

[0033] Furthermore, the cross-section of the nut 6 is L-shaped, and the nut 6 is wrapped around the bottom of the connecting tube 1. The minimum inner diameter of the nut 6 is equal to the inner diameter of the connecting tube 1. An internal thread is provided at the center of the threaded barrel 8, and the internal thread is threadedly connected to the threaded column 11. The diameter of the threaded column 11 is smaller than the diameter of the thermosensitive glass ball 10. The thermosensitive glass ball 10 is installed through the threaded connection of the threaded column 11, and subsequently, through the threaded installation of the nut 6, the thermosensitive glass ball 10 is abutted against the bottom of the plug 5 to support the plug 5.

[0034] Working principle: The plug 5 and the thermosensitive glass ball 10 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is used, the device is first installed and positioned. Further, when a fire occurs, the thermosensitive glass ball 10 bursts due to the high temperature, and then loses its supporting effect on the plug 5. The plug 5 falls due to the water pressure and the like, thereby allowing water to flow through the inside of the connecting pipe 1. The falling water source is guided and dispersed by the plug 5, and further impacted and dispersed by the water distribution plate 9, thereby completing the circumferential dispersion of the water source.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
