Description

Technical Field

[0001] The utility model relates to the technical field of water rescue equipment, in particular to a life belt. Background Art

[0002] Water rescue equipment mainly includes life jackets, life rafts, life-saving radios, maritime self-defense weapons, shark repellents, life belts, etc. Among them, the life belt is a relatively common one in water rescue equipment.

[0003] Existing life belts are usually made of cork, foam plastic or other light materials with a relatively small specific gravity, and are connected with ropes for throwing the life belt. However, due to the relatively light weight of the existing life belt itself, rescuers cannot throw the life belt to drowning people in a relatively far position, which is extremely likely to cause the drowning people to not receive timely rescue. Moreover, the rope generally needs to be fixed by another rope, making it impossible for rescuers to quickly use the life belt when needed, affecting the rescue efficiency of rescuers. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art that the existing life belt has a relatively light weight, resulting in limited use range and inconvenient disassembly and assembly, and to propose a life belt.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A life belt includes a spool body and a belt. A winding shaft for winding the belt is arranged on the spool body. A crank is arranged on the winding shaft. A mounting plate is fixedly sleeved on the winding shaft. A counterweight is arranged between the mounting plate and the spool body;

[0007] One end of the spool body far away from the winding shaft is provided with a fixed shaft. One end of the belt far away from the winding shaft is connected with a pin connected with the fixed shaft.

[0008] Preferably, the spool body is composed of two disc structures. The winding shaft is rotationally installed at the center position of the spool body through a damping bearing.

[0009] Preferably, one end of the winding shaft located in the spool body is fixedly connected with one end of the belt. The crank is fixedly installed on the end of the winding shaft extending outside the spool body.

[0010] Preferably, the cross section of the counterweight is a circular structure, and the counterweight is concentrically arranged with the winding shaft.

[0011] Preferably, the fixed shaft is concentrically arranged with the spool body, and the fixed shaft is a hollow cylinder structure.

[0012] Preferably, a fixing hole for snap-connecting the pin is formed on the fixed shaft.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. By inserting the plug connected to one end of the belt into the fixing hole on the fixing shaft, the utility model avoids the scattering of the belt, helps to ensure the orderliness of the belt, and only needs to insert the plug to complete the fixing of the belt, which helps to improve the disassembly and assembly efficiency of the belt.

[0015] 2. By adding a counterweight block, the overall weight of the wire reel body is increased, thereby avoiding the limited throwing range caused by the too light weight of the wire reel body, which affects the rescue effect. After adding the counterweight block, it helps to improve the movement range of the wire reel body under the same acting force, and then improve the rescue effect of the rescuer on the drowning person.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Referring to Figures 1-4 , a life-saving belt includes a wire reel body 1 and a belt 2. The wire reel body 1 is composed of two disc structures. It should be noted that: the distance between the two disc structures corresponds to the width of the belt 2.

[0023] A winding shaft 3 for winding the belt 2 is provided on the wire reel body 1. The winding shaft 3 is rotatably installed at the center of the wire reel body 1 through a damping bearing. One end of the winding shaft 3 located in the wire reel body 1 is fixedly connected to one end of the belt 2. It should be noted that: the one-way damping of the damping bearing can prevent the self-rotation of the winding shaft 3, which helps to avoid the self-rotation of the winding shaft 3 affected by the friction of the belt 2, and then ensure the stability of the winding shaft 3 when winding the belt 2.

[0024] A crank handle 4 is provided on the winding shaft 3. The crank handle 4 is fixedly installed at one end of the winding shaft 3 extending outside the coil body 1, providing a grasping space for the rescuer, thus ensuring the convenience and comfort of the rescuer during use and helping to improve the winding efficiency of the belt 2 on the winding shaft 3.

[0025] An installation plate 5 is fixedly sleeved on the winding shaft 3. A counterweight 6 is arranged between the installation plate 5 and the coil body 1. The cross-section of the counterweight 6 is a circular structure, and the counterweight 6 is concentric with the winding shaft 3. By adding the counterweight 6, the weight of the life-saving belt is increased, thereby reducing the influence caused by air resistance when the life-saving belt is thrown, so as to improve the rescue range of the life-saving belt, enabling drowning victims in a relatively far position to be rescued in time, increasing the survival probability of the drowning victims, and helping to improve the use effect of the life-saving belt.

[0026] A fixed shaft 7 is arranged at one end of the coil body 1 away from the winding shaft 3. The fixed shaft 7 is concentric with the coil body 1, and the fixed shaft 7 is a hollow cylindrical structure. One end of the belt 2 away from the winding shaft 3 is connected with a pin 8 connected to the fixed shaft 7. Fixing holes for snap-connecting the pin 8 are provided on the fixed shaft 7. The pin 8 cooperates with the fixing holes on the fixed shaft 7 to fix the belt 2, thereby restraining the belt 2 wound on the winding shaft 3, helping to prevent the belt 2 from scattering due to an external collision on the coil body 1. When the rescuer throws the coil body 1, the rescuer grabs one end of the belt 2 connected to the pin 8 to pull the drowning victim up, providing enough grasping space for the rescuer to exert force. It should also be noted that: one end of the belt 2 connected to the pin 8 can be used to tie to a tree or a rock, and during use, only the pin 8 needs to be pulled out from the fixing hole on the fixed shaft 7 to complete the disassembly of the belt 2, which helps to save the preparation time for the rescuer during the rescue work, thereby increasing the survival probability of the drowning victim.

[0027] The functional principle of the present utility model can be described through the following operation method:

[0028] Rotate the crank handle 4 to drive the winding shaft 3 to rotate, so as to quickly wind the belt 2 around the winding shaft 3 through the rotation of the winding shaft 3, and insert the pin 8 connected to the other end of the belt 2 into the fixing hole on the fixed shaft 7;

[0029] When someone needs rescue, pull out the pin 8 from the fixing hole on the fixed shaft 7, throw out the coil body 1. Due to the setting of the counterweight 6, the coil body 1 can be thrown farther. During the process of the belt 2 being thrown out with the coil body 1, it will unfold due to inertia. The drowning victim grabs one end of the belt 2, and the rescuer pulls the drowning victim up forcefully at the other end of the belt 2.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
