Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting water guns, in particular to a compass protection structure and a fire-fighting water gun. Background Art

[0002] A fire hose is a water-shooting tool used for fire extinguishing. When it is connected to a water hose, it can spray out dense and substantial water flow. This tool has the advantages of long range and large water volume. According to the different jet forms and characteristics, fire hoses can be divided into many types. The structure of a compass includes a magnetic needle, a needle shaft, a base plate and an outer shell, which are mainly used for navigation and determining direction. A fire hose with a compass is also a type of fire hose.

[0003] In order to help firefighters better determine the direction in certain complex fire-fighting environments, when a fire hose with a compass is needed for assistance, first connect the water pipe to the water pipe interface, then lift the jet pipe toward the fire point, and then operate the hose body through the control lever to spray the water mixture to the fire point for fire extinguishing. By installing the compass body, firefighters can better determine the direction in smoke-filled or low visibility conditions. However, during the use of a fire hose with a compass, the compass is usually directly displayed in place without additional protection, which makes it easy for the compass to collide with external debris, and then cause the compass to be damaged and affect normal operation, making it easy for firefighters to lose their way in certain complex fire-fighting environments.

DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-Figure 5 The utility model provides a technical solution: a compass protection structure includes a water gun body 1, a compass body 2 and a rotating seat 3, the compass body 2 is embedded and installed in the middle of the outer wall of the water gun body 1, and the rotating seat 3 is welded on the side of the outer wall of the water gun body 1 close to the compass body 2, and a transparent protective cover 4 is connected inside the rotating seat 3, an extension block 5 is docked on one side of the outer wall of the transparent protective cover 4, and a fixing pin 6 is connected inside the extension block 5 through a fixing hole; a spring 7 is sleeved on the outer wall of the fixing pin 6, and the fixing pin 6 is connected to the fixing seat 8 through a storage cavity; guide rods 9 are fixedly connected on both sides of the outer wall of the transparent protective cover 4, and a cleaning scraper 10 is slidably connected to the outer wall of the guide rod 9; a cleaning sponge 11 is connected to the bottom end of the cleaning scraper 10, and the bottom end of the fixing seat 8 is welded to the water gun body 1; an elastic telescopic mechanism is formed between the fixing pin 6, the spring 7 and the fixing seat 8, and the outer wall of the cleaning sponge 11 fits the outer wall of the transparent protective cover 4.

[0025] In specific implementation, when the compass protection structure is used, since the rotating seat 3 is connected to the transparent protective cover 4, the transparent protective cover 4 is first manually rotated to make the extension block 5 close to the fixed seat 8, and then the spring 7 is reset to generate elastic force, so that the fixing pin 6 moves to dock with the extension block 5, and then the transparent protective cover 4 is limited to prevent it from moving at will, so that the compass body 2 is covered by the transparent protective cover 4, preventing the compass body 2 from being visible and colliding with debris, thereby protecting the compass body 2;

[0026] And by pulling the fixing pin 6 in the fixing seat 8, the fixing pin 6 moves and squeezes the spring 7 to deform, until the fixing pin 6 is disconnected from the extension block 5, and then the limit on the transparent protective cover 4 is cancelled;

[0027] Because the guide rod 9 and the cleaning scraper 10 are slidably connected, the cleaning scraper 10 is first manually moved so that the cleaning scraper 10 slides along the guide rod 9. Because the cleaning scraper 10 is connected to the cleaning sponge 11, the movement of the cleaning scraper 10 drives the cleaning sponge 11 to move together. At this time, the cleaning sponge 11 rubs against the transparent protective cover 4, and then cleans the dirt adhered to the outer wall of the transparent protective cover 4 to prevent it from affecting the firefighters' observation of the compass, thereby facilitating protection and cleaning of dirt when the compass is used.

[0028] See also Figure 1 , Figure 2 and Figure 6 It can be seen that a fire water gun, a water gun body 1 is internally connected with a control rod 12, and a water pipe interface 13 is welded on one side of the outer wall of the water gun body 1, and a jet pipe 14 is welded on the other side of the outer wall of the water gun body 1, and an auxiliary mechanism 15 is arranged on the outer wall of the jet pipe 14; the auxiliary mechanism 15 includes a fixing plate A1501, a limiting rope A1502, a wristband A1503, a fixing plate B1504, a limiting rope B1505 and a wristband B1506, a water pipe interface A fixing plate A1501 is butt-jointed to the outer wall of 13, and a limiting rope A1502 is connected to the middle of the outer wall of the fixing plate A1501; a hand ring A1503 is connected to the side of the limiting rope A1502 away from the fixing plate A1501, and a fixing plate B1504 is butt-jointed to the outer wall of the jet pipe 14; a limiting rope B1505 is connected to the middle of the outer wall of the fixing plate B1504, and a hand ring B1506 is connected to the side of the limiting rope B1505 away from the fixing plate B1504.

[0029] In specific implementation, when the fire hose is used, since the fixing plate A1501 is connected to the water pipe interface 13, and the fixing plate B1504 is connected to the jet pipe 14, the limiting rope A1502 is manually pulled first, and then the left hand passes through the bracelet A1503, and then the limiting rope B1505 is pulled, and then the right hand passes through the bracelet B1506. Therefore, when the firefighter uses the fire hose and the fire hose slips due to fatigue, the limiting rope A1502 and the limiting rope B1505 will limit it to prevent the fire hose from falling and colliding with the ground, thereby facilitating the limiting and preventing the fire hose from falling when it is used.

[0030] To sum up, when using the compass protection structure and the fire hose, first connect the water pipe to the water pipe interface 13, then lift the jet pipe 14 toward the fire point, and then operate the water hose body 1 through the control lever 12, so that the water mixture is sprayed toward the fire point to extinguish the fire, and by installing the compass body 2, firefighters can better determine the direction in the case of smoke or low visibility, which helps to improve the fire extinguishing efficiency and ensure the safety of firefighters; this is the prior art and will not be elaborated on here. The compass body 2 is covered by the transparent protective cover 4 to prevent the compass body 2 from being exposed and colliding with debris, and the cleaning scraper 10 is moved to allow the cleaning sponge 11 to clean the dirt adhered to the outer wall of the transparent protective cover 4 to prevent it from affecting the firefighters' viewing of the compass. When the firefighter's fire hose slips due to fatigue, the auxiliary mechanism 15 is used to limit it to prevent the fire hose from falling and colliding with the ground. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
