Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler heads, in particular to a safety fire sprinkler head. Background Art

[0002] The working principle of fire sprinkler heads is mainly based on changes in temperature and pressure. Nozzles that respond to temperature, such as glass thermal bubble nozzles and electronic temperature-sensitive nozzles, will expand under the high temperature of the fire, thereby causing water to spray. Nozzles that respond to pressure, such as wet nozzles and dry nozzles, spray water through pressure sensing. They are used to automatically or manually start when a fire occurs, and control and extinguish the fire by sprinkling water.

[0003] The existing safety fire sprinkler can refer to the Chinese utility model patent with the authorization announcement number CN211273288U, which discloses a safety fire sprinkler, "including a mounting seat, a top cover and a plug; a retaining ring is welded on the inner wall of the mounting seat, and a top cover with a plug is installed on the mounting seat; a return spring is installed between the retaining ring and the top cover; a guide plate with a conical structure is welded on the base; and a conical head facing the glass tube is welded on the crushing block."

[0004] When the above device is in use, the existing device uses a tool to hammer the base and the conical head to break the glass tube when the glass tube fails or needs to be broken in advance, so that the nozzle can spray water outward. However, when the device is actually used, the installation height of the device is at a high place, and it is difficult to knock the bottom of the device manually with a tool hammer. In addition, there are certain defects in the triggering mechanism of the fire sprinkler. Often, the glass ball will break and enter the fire extinguishing mechanism only when the fire spreads too much. For this reason, it is necessary to avoid the problem that the temperature threshold of the glass ball does not meet the standard and cannot enter the triggering stage. Therefore, a safe fire sprinkler that solves the above problems is needed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model provides a safe fire sprinkler head, which has the advantages of strong practicability, heat conduction temperature, temperature accelerated heat collection, manual start, etc., and solves the problems raised by the above-mentioned background technology.

[0006] The utility model provides the following technical solutions: a safe fire sprinkler, comprising a mounting seat, a threaded tube fixedly connected to the top of the mounting seat, a water channel opened in the inner cavity of the threaded tube, a plugging head sleeved on the inner wall of the water channel, a glass ball provided at the bottom of the plugging head, a connecting frame fixedly connected to the bottom of the mounting seat, a bottom support fixedly connected to the other end of the connecting frame, a mounting frame fixedly connected to the outer wall of the bottom support, a heat-conducting brass provided on the inner wall of the mounting frame, a heat collecting head fixedly connected to the outer wall of the heat-conducting brass, a connector fixedly installed at the bottom of the mounting frame, one end of a reset spring connected to the bottom of the connector, an end of the reset spring away from the connector is connected to a connecting head, a breaker is provided on the top of the connecting head, and a rubber wire is fixedly connected to the bottom of the connecting head.

[0011] As a preferred technical solution of the utility model, the top of the crusher is in the shape of a cone head, and the bottom of the glass ball is provided with a thin flat layer.

[0012] Compared with the prior art, the utility model has the following beneficial effects:
