Description

Technical Field

[0001] This utility model relates to the field of rope throwing bag technology, specifically a rope throwing bag suitable for water rescue. Background Technology

[0002] Rescue refers to the entire process by which individuals or people are rescued when they encounter disasters or other extraordinary circumstances (including accidents, sudden dangerous events, etc.); while rescue work refers to the undertaking that can make long-term and comprehensive preparations and can carry out rescue operations anytime and anywhere. In water rescue, a rescue throwing rope bag is often used. One end of the towing rope is held in the rescuer's hand, and the other end of the throwing rope bag, together with the towing rope inside the bag, is thrown to the side of the person being rescued.

[0003] The existing Chinese utility model patent with publication number CN220147557U discloses a rope-throwing bag for water rescue, including a tow rope and a rope-throwing bag. The rope-throwing bag is located on the left side of the tow rope, and a fixing component is provided at the bottom of the outer wall of the rope-throwing bag. This utility model provides a rope-throwing bag for water rescue. Through the cooperation of the Velcro on the back of the pull bar and the Velcro on the front surface of the ring, the pull bar is fixed, thereby tightening the diameter of the ring and the pull bar. Through the cooperation of the fixing ring, the ring, and the limiting ring, the arm of the person being rescued can be easily and quickly secured. The cooperation of these components allows the user to easily and quickly secure themselves, thus buying precious rescue time.

[0004] The aforementioned rope pack, being made of fabric, sinks after absorbing water, preventing it from floating on the surface and causing the traction rope to sink as well. This makes it difficult for the person being rescued to grab the traction rope. Furthermore, to ensure smooth release of the traction rope during the next use, it needs to be coiled inside the rope pack during retrieval. To limit the coiling of the traction rope, the opening in the rope pack is generally small, making the coiling and retrieval process very inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rope-throwing bag suitable for water rescue, which solves the problems of the towing rope and the bag sinking after being thrown, as well as the inconvenience of retrieval.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rope bag suitable for water rescue, comprising a rope bag, wherein a traction mechanism is provided inside the rope bag. A pulling component, located inside the rope bag, is used to pull a person who has fallen into the water; The buoyancy assembly includes a connecting ring fixedly installed at the rear end of the rope bag, a hose fixedly installed at the rear end of the connecting ring, an air valve movably installed at the rear end of the hose, an air cylinder movably installed at the rear end of the air valve, a waterproof plug inserted into the water inlet of the air valve, a safety rope fixedly installed at the bottom end of the waterproof plug, and an air bladder fixedly installed at the front end of the connecting ring.

[0007] Preferably, a drawstring is sewn onto the outside of the rope bag, a zipper is sewn onto the center of the rope bag, and an adhesive strip is fixedly installed on the outside of the rope bag.

[0008] Preferably, the rope bag has a cylindrical structure, with the rear end connected and the center horizontally separated. The upper and lower sides of the rope bag are connected by a zipper, and the adhesive strip is installed at the connection points on the left and right sides of the rope bag.

[0009] Preferably, the traction assembly includes magnetic rings fixedly installed on the upper and lower sides of the front end of the rope bag, a copper ring fixedly installed inside the magnetic rings, a traction rope wound around the outside of the airbag, a safety buckle fixedly installed at the front end of the traction rope, a connecting buckle fixedly installed on one side of the safety buckle, one end of the traction rope fixedly connected to the inner wall of the rope bag, and the surface of the connecting buckle is provided with a groove structure that fits into the safety rope.

[0010] Preferably, the hose is connected to the air bladder via a connecting ring, the rear end of the hose is a metal structure, and the inner wall is provided with a groove that matches the thread at one end of the air valve. The air valve is connected to the hose via a threaded structure, and the gas cylinder is installed at the rear end of the air valve via a threaded structure.

[0011] Preferably, the waterproof plug is made of rubber and has a diameter larger than the diameter of the air valve inlet. The front end of the safety rope is provided with a disc-shaped protrusion. The front end of the safety rope passes through the connecting buckle through a groove on the surface of the connecting buckle. The air bladder is located at the center of the rope bag. Beneficial effects

[0012] This invention provides a rope-throwing bag suitable for water rescue. Compared with the prior art, it has the following advantages: (1) This rope throwing bag suitable for water rescue, through the setting of the zipper, first open the zippers on both sides of the center of the rope bag, then separate the magnetic ring, so that the rope bag unfolds, providing operating space for the winding of the traction rope, and then rewind the traction rope to the outside of the airbag located in the center of the rope bag. During the winding process, the closing state of the zipper can be gradually adjusted according to the winding progress of the traction rope, and the binding force of the zipper can be used to restrict the position of the wound part of the traction rope. Finally, the zipper is completely closed. At this time, the magnetic ring is re-adsorbed, and the copper ring is once again surrounded to form a protective channel, stably restraining the entire bundle of traction rope inside the rope bag, and completing the retrieval. During the maintenance stage, when the air valve is rotated counterclockwise to connect with the threaded connection of the hose and the air valve is removed, the gas inside the airbag is naturally discharged through the hose, and the airbag deflates, preventing the airbag from affecting the smooth discharge of the traction rope during the throwing process.

[0013] (2) This rope-throwing bag, suitable for water rescue, utilizes an airbag. When the rope bag is thrown, as the traction rope slides out of the bag, the distance between the safety buckle and the bag increases, pulling the safety rope and thus removing the waterproof plug from the inlet of the air valve. When the rope bag falls into the water, the weight of the air valve and cylinder causes the hose to deform and bend, submerging the air valve below the water surface. At this point, water can easily enter the air valve, dissolving the water-soluble baffle inside. After the baffle dissolves, the compressed spring inside the air valve releases its elastic potential energy, pushing the pin to puncture the cylinder. The compressed gas in the cylinder enters the airbag through the hose and connecting ring, causing the airbag to expand rapidly. The expanded airbag generates sufficient buoyancy to counteract the weight of the rope bag, traction rope, and other components, thus lifting the rope bag and traction rope onto the water surface and preventing them from sinking.

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a rope bag suitable for water rescue, including a rope bag 1, a pull rope 11 sewn on the outside of the rope bag 1, a zipper 12 sewn in the center of the rope bag 1, and an adhesive strip 13 fixedly installed on the outside of the rope bag 1. The rope bag 1 has a columnar structure, connected at the rear end and horizontally separated in the center. The upper and lower sides of the rope bag 1 are connected by the zipper 12, and the adhesive strip 13 is installed at the connection points on the left and right sides of the rope bag 1.

[0017] Specifically, the rope bag 1 can wrap the traction rope 213 and restrict the position of the traction rope 213. The rope bag 1 is made of two half-cylindrical structures sewn together at the rear end, and the left and right sides are connected by zippers 12. The rope bag 1 can be opened by zippers 12 during the process of retrieving the traction rope 213, and the rope bag 1 can be retracted according to the winding progress. The pull rope 11 can provide a force point during the throwing of the rope bag 1 to facilitate the throwing.

[0018] The rope bag 1 is equipped with a traction mechanism 2 inside. The pulling assembly 21 is located inside the rope bag 1 and is used to pull a person who has fallen into the water. The pulling assembly 21 includes magnetic rings 211 fixedly installed on the upper and lower sides of the front end of the rope bag 1, copper rings 212 fixedly installed inside the magnetic rings 211, a traction rope 213 wrapped around the outside of the airbag 227, a safety buckle 214 fixedly installed at the front end of the traction rope 213, a connecting buckle 215 fixedly installed on one side of the safety buckle 214, one end of the traction rope 213 fixedly connected to the inner wall of the rope bag 1, and the surface of the connecting buckle 215 is provided with a groove structure that fits into the safety rope 226.

[0019] Specifically, the magnetic ring 211 can attract each other when the zippers 12 on both sides of the rope bag 1 are closed, so that the copper ring 212 inside the magnetic ring 211 forms a tube structure. After the rope bag 1 is thrown out, it can prevent the traction rope 213 from wearing down the rope bag 1. The traction rope 213 can easily pull the person who has fallen into the water. The safety buckle 214 can limit the front end of the traction rope 213 and prevent the front end of the traction rope 213 from flying out due to inertia. The connecting buckle 215 can limit the position of the front end of the safety rope 226.

[0020] The buoyancy assembly 22 includes a connecting ring 221 fixedly installed at the rear end of the rope bag 1. A hose 222 is fixedly installed at the rear end of the connecting ring 221. An air valve 223 is movably installed at the rear end of the hose 222. An air cylinder 224 is movably installed at the rear end of the air valve 223. A waterproof plug 225 is inserted into the water inlet of the air valve 223. A safety rope 226 is fixedly installed at the bottom end of the waterproof plug 225. An air bladder 227 is fixedly installed at the front end of the connecting ring 221. The hose 222 communicates with the air bladder 227 through the connecting ring 221. The rear end of 22 is a metal structure, and the inner wall is provided with a groove that matches the thread of one end of the air valve 223. The air valve 223 is connected to the hose 222 through the threaded structure. The gas cylinder 224 is installed at the rear end of the air valve 223 through the threaded structure. The waterproof plug 225 is made of rubber and has a diameter larger than the inlet diameter of the air valve 223. The front end of the safety rope 226 is provided with a disc-shaped protrusion. The front end of the safety rope 226 passes through the connecting buckle 215 through the groove on the surface of the connecting buckle 215. The air bag 227 is located at the center of the rope bag 1.

[0021] Specifically, the connecting ring 221 connects the hose 222 to the airbag 227. The hose 222 deforms due to the weight of the air cylinder 224 and the air valve 223 when the rope bag 1 is thrown and falls to the water surface, ensuring that the air valve 223 is below the water surface so that water can enter the air inlet of the air valve 223. The waterproof plug 225 seals the water inlet of the air valve 223 when not in use, preventing the water-soluble baffle inside the air valve 223 from dissolving when not in use. The bottom end of the waterproof plug 225 forms a flexible connection with the connecting buckle 215 through the safety rope 226. Because the safety buckle 214 is in contact with the rope bag 1 during the throwing process... As the distance between them increases, the safety rope 226 will pull the waterproof plug 225, causing it to detach from the air valve 223. This allows water to enter the air valve 223 and dissolve the baffle. The spring inside the air valve 223 is compressed due to the water-soluble baffle. After the baffle dissolves, the spring will drive the pin to puncture the front end of the gas cylinder 224. The compressed gas inside the gas cylinder 224 will enter the air bag 227 under the guidance of the hose 222, so that the air bag 227 can inflate normally after contacting the water surface, providing buoyancy for the rope bag 1. Meanwhile, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0022] During the operation, the rescuer throws rope bag 1 out of the hand rope 11. Due to inertia, rope bag 1 and the internal traction rope 213 move away from safety buckle 214. The traction rope 213 slides out along the channel enclosed by magnetic ring 211 and copper ring 212. At the same time, safety rope 226 pulls the waterproof plug 225 to disengage from air valve 223. After rope bag 1 falls into the water, hose 222 deforms and bends under the weight of air valve 223 and gas cylinder 224, causing air valve 223 to sink into the water. The water dissolves the water-soluble baffle inside air valve 223, triggering spring pin to puncture gas cylinder 224. Gas is then injected into air bag 227 through hose 222, causing it to expand and generate buoyancy. When retrieving the tow rope 213 after the rescue is completed, first unzip the zipper 12 of the rope bag 1 to separate the magnetic ring 211 and release the copper ring 212 from its encircling state. Then, wind and retrieve the tow rope 213. As the tow rope 213 gradually winds back around the outside of the airbag 227, the zipper 12 can be gradually closed according to the winding progress to restrict the position of the wound tow rope 213. Finally, the zipper 12 is completely closed, and the entire bundle of tow rope 213 is fixed by the constraint force of the zipper 12 to prevent it from loosening. At the same time, the magnetic ring 211 re-attaches, and the copper ring 212 closes again, providing a protective channel for the next throw. Then, rotate the threaded connection between the air valve 223 and the hose 222 counterclockwise. After removing the air valve 223, the gas inside the airbag 227 is naturally discharged through the hose 222, and the airbag 227 gradually deflates for easy storage. Open the outer shell of the air valve 223 to replace the new water-soluble baffle, insert the new air cylinder 224 and tighten it, then screw the air valve 223 back into the hose 222, and finally reset the waterproof plug 225 to complete the maintenance.
