Description

Technical Field

[0001] This utility model relates to the technical field of fire-fighting equipment, specifically to an anti-detachment type fire hose. Background Technology

[0002] Fire hoses are water-spraying tools used for extinguishing fires. When connected to a fire hose, they spray a dense and powerful stream of water. They have advantages such as long range and large water volume. Based on different jet patterns and characteristics, they can be divided into: straight-stream hoses, spray hoses, and multi-purpose hoses. The most commonly used hoses are straight-stream and spray hoses. However, due to the diverse nature of fire and disaster relief situations, firefighters often need to carry hoses on foot to the best fire-fighting area. This involves running while holding the hose, and upon reaching the fire location, immediately connecting the hose and spraying water to extinguish the fire. During this process, firefighters cannot get a moment's rest. Therefore, during prolonged handling of the fire hose, water droplets adhere to the outer wall of the hose, and firefighters experience significant physical exertion, greatly increasing the risk of the hose slipping from their hands.

[0003] However, existing fire hoses have a simple upper structure, which can only spray water after connecting to fire pipelines. After prolonged physical exertion, the upper part of the fire hose held by firefighters does not have an anti-detachment structure, which increases the probability of the fire hose falling from the hands of firefighters who have exhausted themselves, thus increasing the probability of the fire hose being damaged. If a strap is directly added to the upper part of the fire hose to bind it to the firefighter's arm, it will restrict the angle and direction of the firefighter's arm swing, thereby affecting the efficiency of fire extinguishing. In view of this, this design proposes an anti-detachment fire hose. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-detachment fire hose nozzle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes an anti-detachment fire hose, comprising a hose body and an anti-detachment mechanism installed on the outer wall of the hose body;

[0006] The anti-detachment mechanism includes a retaining ring sleeved on the outer wall of one end of the water gun body. A first annular groove is provided in the middle of the outer wall of the retaining ring. A rotating ring is rotatably connected to the inner wall of the first annular groove. A connecting block is fixedly provided on one side of the rotating ring. A first connecting frame is rotatably connected to one side of the connecting block. A connecting rod is rotatably connected to the inner wall of the first connecting frame. A second connecting frame is sleeved on the outer wall of one end of the connecting rod, and the outer wall of one end of the connecting rod is rotatably connected to the inner wall of the second connecting frame. A rubber ring is fixedly provided on one side of the outer wall of the second connecting frame.

[0007] In one example, a limiting ring is fixedly provided at the middle position of the inner wall of the retaining ring, and a limiting groove is provided on the outer wall of one end of the water gun body.

[0008] In one example, the outer wall of the limiting ring is interlocked with the inner wall of the limiting groove, and the limiting ring is limited in the inner wall of the limiting groove, preventing the retaining ring from sliding on the outer wall of the water gun body.

[0009] In one example, a handle is fixedly provided on one edge of the outer wall of the water gun body, and a rubber sleeve is fitted on the outer edge of the outer wall of the water gun body located on the side of the retaining ring.

[0010] In one example, water pipe docking blocks are fixedly provided at both edges of one end of the inner wall of the water gun body, and a sealing gasket is fixedly provided at one end of the inner wall of the water gun body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an anti-detachment mechanism on the outer wall of the water gun body, when firefighters use it, they pass their arms through the rubber ring on the anti-detachment mechanism and hold the water gun body. When the firefighter is holding the water gun to extinguish the fire, the connecting rod connects the retaining ring on the water gun to the rubber ring on the firefighter's arm. At the same time, the second connecting frame allows the rubber ring to rotate up and down on the connecting rod. The connecting rod can rotate left and right on the connecting block on one side of the rotating ring through the first connecting frame. The rotating ring can rotate 360 ​​degrees in the annular groove on the retaining ring. The connecting rod can also be folded according to the distance between the arm and the water gun body to adjust the length of the anti-detachment mechanism. When the firefighter connects and operates the fire gun through the anti-detachment mechanism, the arm swing is not easily restricted. This solves the problems in the prior art where the fire gun is easily slipped and damaged when firefighters hold the fire gun for a long time and with great physical exertion, and the problem of the arm being restricted and the fire extinguishing efficiency being affected by the use of straps to bind the water gun to the firefighter's arm.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-5 This utility model provides a technical solution: an anti-detachment fire hose, including a hose body 1 and an anti-detachment mechanism 2 installed on the outer wall of the hose body 1;

[0020] The anti-detachment mechanism 2 includes a retaining ring 201 sleeved on the outer wall of one end of the water gun body 1. A first annular groove 202 is provided in the middle of the outer wall of the retaining ring 201. A rotating ring 203 is rotatably connected to the inner wall of the first annular groove 202. A connecting block 204 is fixedly provided on one side of the rotating ring 203. A first connecting frame 205 is rotatably connected to one side of the connecting block 204. A connecting rod 206 is rotatably connected to the inner wall of the first connecting frame 205. A second connecting frame 207 is sleeved on the outer wall of one end of the connecting rod 206, and the outer wall of one end of the connecting rod 206 is rotatably connected to the inner wall of the second connecting frame 207. A rubber ring 208 is fixedly provided on one side of the outer wall of the second connecting frame 207.

[0021] In use, firefighters connect the main body 1 of the fire hose to the fire hydrant pipe, control the water pressure through the main body 1, and spray water jets for fire extinguishing. When operating the fire hose, firefighters can first slip the rubber ring 208 on the upper anti-detachment mechanism 2 onto their arm, then use the hand passing through the rubber ring 208 to grip the outer wall of the main body 1, while simultaneously gripping the handle 3 at the rear edge of the main body 1 with the other hand. When spraying water, the connecting rod 206 connects the retaining ring 201, which is locked onto the outer wall of the main body 1, to the second connecting bracket 207, which is fixed to the outer wall of the rubber ring 208. Simultaneously, the connecting rod 206 can rotate on the second connecting bracket 207, as per the instruction manual. Figure 3 As shown, the first connecting frame 205, which is rotatably connected to the other end of the connecting rod 206, is rotatably connected to the outer wall of the rotating ring 203 via the connecting block 204, as per the instruction manual. Figure 4As shown, the rotating ring 203 can rotate in the annular groove 202 on the outer wall of the retaining ring 201, so that when the firefighter holds the fire hose and his arm passes through the rubber ring 208 on the anti-detachment mechanism 2, the rubber ring 208 rotates up and down on the connecting rod 206 through the second connecting frame 207, and the connecting rod 206 can rotate left and right on the connecting block 204 through the first connecting frame 205. At the same time, the rotating ring 203 connected to it can also rotate in a circle in the annular groove 202 on the retaining ring 201, so that the firefighter can hold the fire hose without affecting the free swing of his arm after cooperating with the anti-detachment mechanism 2. When adjusting the direction and angle of the water spray, the arm can be operated freely without restraint. This solves the problems in the existing technology that firefighters who hold the fire hose for a long time and with great physical exertion are prone to slipping and falling to the ground and being damaged, and the problem that using straps to bind the fire hose to the firefighter's arm causes arm restraint and affects the fire extinguishing efficiency.

[0022] Furthermore, a limiting ring 209 is fixedly provided in the middle of the inner wall of the retaining ring 201, and a limiting groove 210 is opened on the outer wall of one end of the water gun body 1. The limiting ring 209 can also rotate in the limiting groove 210. In conjunction with the rotating ring 203 rotating in the annular groove 202 on the outer wall of the retaining ring 201, the angle adjustment of the anti-detachment mechanism 2 is smoother and less likely to generate greater resistance when the firefighter adjusts the direction of fire extinguishing by swinging his arm.

[0023] The outer wall of the limiting ring 209 is interlocked with the inner wall of the limiting groove 210. The limiting ring 209 is limited in the inner wall of the limiting groove 210, preventing the retaining ring 201 from sliding on the outer wall of the water gun body 1. By setting the limiting ring 209 on the inner wall of the retaining ring 201, the limiting ring 209 is inserted into the limiting groove 210 opened on the outer wall of the water gun body 1, thus limiting it. This prevents the retaining ring 201 from sliding on the outer wall of the water gun body 1 with the anti-detachment mechanism 2, preventing the firefighter from having to constantly adjust the position of the anti-detachment mechanism 2 during use, which would affect the use by the firefighter.

[0024] Furthermore, a handle 3 is fixedly provided on one edge of the outer wall of the water gun body 1, and a rubber sleeve 4 is fitted on the outer edge of the outer wall of the water gun body 1 on the side of the retaining ring 201. When firefighters use this fire gun, one hand holds the handle 3, and the other hand passes through the anti-dislodgement mechanism 2 to hold the area on the water gun body 1 where the rubber sleeve 4 is provided, making the water gun more stable when operated. At the same time, holding the area with the rubber sleeve 4 increases the friction between the hand and the water gun and reduces the risk of it falling off.

[0025] Furthermore, water pipe docking blocks 5 are fixedly installed at both edges of one end of the inner wall of the water gun body 1, and a sealing gasket 6 is fixedly installed at one end of the inner wall of the water gun body 1. The two docking blocks 5 at one end of the inner wall of the water gun body 1 are docked with the fire pipe, thereby locking it in place. At the same time, the end of the fire pipe is pressed against the inner wall of the water gun body 1 and contacts and presses the sealing gasket 6 therein, thereby achieving a sealing effect at the connection and improving the effect of the water gun spraying water jet.

Each embodiment focuses on its differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so they are described more simply; relevant parts can be referred to the descriptions of the method embodiments.
