Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and more specifically, to a fire sprinkler. Background Technology

[0002] Fire sprinkler guns are fire-fighting equipment used to spray high-pressure water for fire extinguishing. Currently, Chinese patent announcement number CN209237225U discloses a nozzle for fire sprinkler guns. In this nozzle structure, the three water inlets formed by the first water inlet, the second water inlet, and the third water inlet are arranged in a triangular distribution, which results in the disadvantage of a large nozzle size and poor structural compactness, making it unfavorable for the use and carrying of the nozzle. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fire sprinkler gun that has the advantages of small size and high compact structure, thus making it convenient to use and carry.

[0004] This utility model provides a fire sprinkler gun, including a nozzle and a gun body; the nozzle has a first water passage, a second water passage, and a third water passage inside, which are parallel to each other and arranged in a straight line inside the nozzle; the left and right ends of the first water passage form a first water inlet and a first water outlet, respectively, and the inner diameter of the first water passage gradually decreases from the first water inlet to the first water outlet; the left and right ends of the second water passage form a second water outlet and a second water inlet, respectively, and the inner diameter of the second water passage gradually decreases from the second water inlet to the second water outlet; the left and right ends of the third water passage form a third water inlet and a third water outlet, respectively, and the inner diameter of the third water passage gradually decreases from the third water inlet to the third water outlet; the first, second, and third water inlets have the same diameter and are used for detachable connection with the front end of the gun body.

[0005] By adopting the above-mentioned structure, this utility model can improve the utilization rate of the internal space of the nozzle by arranging the first water passage, the second water passage, and the third water passage in parallel and in a straight line inside the nozzle, and by reducing the inner diameter of the second water passage in the opposite direction to the inner diameter of the first water passage and the inner diameter of the third water passage. This reduces the size of the nozzle and improves its structural compactness, thereby making the use and carrying of the nozzle more convenient, and also making the use and carrying of fire sprinkler guns more convenient.

[0006] In one possible implementation, the cross-sections of the first and third water outlets are both circular, and the diameter of the first water outlet is smaller than that of the third water outlet. The cross-section of the second water outlet is oblong. By adopting this structure, the three different types of water outlets can meet the water spraying needs during the fire extinguishing process, that is, firefighters can choose to use different types of water outlets according to the water spraying needs.

[0007] In one possible implementation, the extension direction of the second outlet is perpendicular to the vertical connecting line of the axis of the first water passage and the axis of the third water passage; by adopting this structure, the size of the nozzle can be further reduced, that is, the structure of the nozzle can be made more compact, so as to facilitate the use and carrying of the nozzle.

[0008] In one possible implementation, the inner walls of the first, second, and third water inlets are all provided with internal threads. The first, second, and third water inlets are used to connect to the front end of the gun body and provide circumferential sealing. With this structure, when the nozzle is connected to the gun body, the first, second, and third water inlets can be easily connected to or disconnected from the front end of the gun body.

[0009] In one possible implementation, a threaded connector is provided at the front end of the gun body, and a sealing ring is coaxially embedded on the outer wall of the threaded connector; the threaded connector is used to be threadedly connected to the first water inlet, the second water inlet, or the third water inlet and circumferentially sealed by the sealing ring; by adopting this structure, after the threaded connector is threadedly connected to the first water inlet, the second water inlet, or the third water inlet, the nozzle can be reliably connected to the gun body, and under the action of the sealing ring, the threaded connector can reliably achieve the purpose of circumferential sealing between the first water inlet, the second water inlet, or the third water inlet.

[0014] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] See Figure 1-5 As shown in the figure, this application discloses a fire sprinkler gun, including a nozzle 1 and a gun body 2; the nozzle 1 is provided with a first water passage 11, a second water passage 12 and a third water passage 13 inside, the first water passage 11, the second water passage 12 and the third water passage 13 are parallel to each other and arranged in a straight line inside the nozzle 1; the left and right ends of the first water passage 11 form a first water inlet 111 and a first water outlet 112 respectively, and the inner diameter of the first water passage 11 gradually decreases from the first water inlet 111 to the first water outlet 112, the second water passage 111, the second water passage 12 and the third water outlet 13 are ... the second water passage 111, the second water passage 12 and the third water outlet 13 are arranged in a straight line inside the nozzle 1; the left and right ends of the first water passage 11 form a first water inlet 111 and a first water outlet 112 respectively, and the inner diameter of the first water passage 11 gradually decreases from the first water inlet 111 to the first water outlet 112, the second water inlet 111, the second water outlet 112 and the third water outlet 112 are arranged in a straight line inside the nozzle 1; the left and right ends of the first water passage 11 form a first water inlet 111 The left and right ends of the water passage 12 form a second water outlet 121 and a second water inlet 122, respectively, and the inner diameter of the second water passage 12 gradually decreases from the second water inlet 122 to the second water outlet 121. The left and right ends of the third water passage 13 form a third water inlet 131 and a third water outlet 132, respectively, and the inner diameter of the third water passage 13 gradually decreases from the third water inlet 131 to the third water outlet 132. The first water inlet 111, the second water inlet 122 and the third water inlet 131 have the same diameter and are used for detachable connection with the front end of the gun body 2.

[0016] See you again Figure 4As shown, the cross-sections of the first water outlet 112 and the third water outlet 132 are both circular, and the diameter of the first water outlet 112 is smaller than the diameter of the third water outlet 132. The cross-section of the second water outlet 121 is oblong. By adopting this structure, the three different types of water outlets can meet the water spraying needs during the fire extinguishing process, that is, firefighters can choose to use different types of water outlets according to the water spraying needs.

[0017] See you again Figures 3-5 As shown, the extending direction of the second outlet 121 is perpendicular to the vertical connecting line of the axis of the first water passage 11 and the axis of the third water passage 13. By adopting this structure, the size of the nozzle can be further reduced, making the nozzle structure more compact for easier use and carrying. Furthermore, the perpendicularity of the extending direction of the second outlet to the vertical connecting line of the axis of the first water passage and the axis of the third water passage means: (e.g.) Figures 3-5 As shown, when the nozzle is in a vertical position, the second outlet is in a horizontally extending position, and the width of the second outlet in the horizontal direction is less than or equal to the diameter of the first inlet and the diameter of the second inlet.

[0018] The inner walls of the first water inlet 111, the second water inlet 122, and the third water inlet 131 are all provided with internal threads. The first water inlet 111, the second water inlet 122, and the third water inlet 131 are used to connect to the front end of the gun body 2 and provide circumferential sealing.
