Technical Field
[0001] This utility model belongs to the field of float technology, specifically relating to a portable water rescue and lifesaving float. Background Technology
[0002] In traditional water rescue equipment, rescue floats typically employ a fixed-length single-buoy design, resulting in a very limited effective range. Due to the insufficient length of the float itself, it must be used in conjunction with a pull rope to achieve long-distance rescues. However, this design has significant drawbacks in practical applications: when rescuers throw the float, the short float lacks sufficient resistance to deviation in the water, making it highly susceptible to currents and prone to drifting away from the target position. Simultaneously, the pull rope easily becomes tangled and knotted in the water, affecting throwing accuracy. Furthermore, this "short float + pull rope" combination often requires multiple attempts to successfully deliver the float, severely reducing rescue efficiency and potentially delaying rescue opportunities in emergencies. Especially in open water or fast-flowing environments, the current can easily wash the float away from the person in the water. Therefore, existing technologies suffer from the problem of rescue floats being easily swept away by currents, making it difficult for the person in the water to grab them. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a portable water rescue float, which solves the problem that the existing life-saving float is easily swept away by the water flow, making it inconvenient for people who fall into the water to grab it.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A portable water rescue and lifesaving float, comprising a strip-shaped float body;
[0006] The floats consist of two floats placed side by side;
[0007] Each end of the float body is fixed with a turntable, and the central axes of the two turntables are placed parallel to each other.
[0008] Each turntable is rotatably connected to a coaxially placed shaft;
[0009] Both shafts are connected to a housing at their upper ends, and the shafts are fixedly connected to the housing.
[0010] A locking component is provided between the housing and the two turntables. The locking component is used to lock or release the rotation of the turntables.
[0011] The locking components all include a slide rod placed coaxially with the turntable, the slide rod is slidably connected to the housing, and a locking block is fixed to the end of the slide rod near the turntable. The distance between the housing and the turntable is greater than or equal to the length of the locking block along the axis of the turntable.
[0012] Each turntable has a groove on its upper end that matches the locking block. The grooves are multiple grooves that are evenly distributed in a ring around the central axis of the corresponding turntable.
[0013] The upper ends of the slide rods all slide through the upper surface of the housing, and each slide rod has a handle fixed to its upper end.
[0014] The shell is a hollow shell;
[0015] The locking assembly also includes a fixed plate that is fixedly sleeved on the slide rod. The fixed plate is slidably connected inside the housing. Each slide rod is sleeved with a spring. The lower end of each spring is fixed to the upper end of the fixed plate, and the upper end of each spring is fixed to the inner top surface of the housing.
[0016] The slide bar is provided with grooves on its peripheral wall, and the grooves are placed coaxially with the slide bar. The upper end of the shell wall is provided with protrusions that match the grooves.
[0017] The upper edge of the groove is provided with a rounded chamfer;
[0018] Each float has a fixed handrail frame.
[0019] Multiple handrail frames are provided on the float itself.
[0020] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:
[0021] Fixed connection: refers to a connection method in which two or more components are tightly connected together by welding, gluing or other methods, and cannot be easily separated.
[0022] Rotary connection: refers to a connection where two parts can rotate relative to each other, and is often used in mechanical devices when rotational motion is required.
[0023] The beneficial effects of this utility model are:
[0024] 1. This application, through its deployable double-buoy structure design, enables the life-saving float to flexibly adjust its shape according to rescue needs, showing significant advantages, especially in turbulent water environments. When a long-distance rescue is required, rescuers can quickly rotate and unfold the two floats into a straight line, extending the overall length to nearly twice its original length. Rescuers can hold one end and extend the other end towards the person in the water, solving the problem that the existing method of throwing life-saving floats easily causes the life-saving float to be swept away by the water flow, making it easier for the patient to grab it effectively.
[0025] If the person in the water grabs one end of the rescue float, and the rescuer is on shore, the person can be pulled back directly. If both the rescuer and the person in the water are in the water, the rescuer can pull the person to their side and then rotate and adjust the two floats to form a V-shape. This provides independent buoyancy support for both parties and forms a V-shaped deflector to reduce the impact of lateral water flow, significantly improving the safety and reliability of mutual rescue in the water.
[0026] 2. Through the coordinated design of the locking block, groove, and slide bar, manually pulling or releasing the slide bar can drive the locking block to extend into or move away from the groove, so as to lock or release the rotation of the turntable; at the same time, with the help of the spring and the fixed plate, the stability of the locking block when inserted into the groove is maintained, and the turntable is prevented from accidentally deflecting.

[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0033] This combination Figures 1 to 4This invention describes an embodiment of a portable water rescue lifesaving float. Specifically, the portable water rescue lifesaving float is constructed with a split structure, comprising a float body 100, a turntable 200, a rotating shaft 300, a housing 400, and a locking component 500. This application utilizes an expandable double float body 100 structure design, allowing the lifesaving float to flexibly adjust its shape according to rescue needs, exhibiting significant advantages, especially in turbulent water environments. When a long-distance rescue is required, rescuers can quickly rotate and unfold the two float bodies 100 into a straight line, extending the overall length to nearly twice its original length. Rescuers can hold one end and extend the other end towards the person in the water, solving the problem in existing technologies where throwing lifesaving floats easily causes them to be swept away by the current, thus facilitating effective grabbing by the patient.
[0034] If the person in the water grabs one end of the rescue float, and the rescuer is on shore, they can pull the person back directly. If both the rescuer and the person in the water are in the water, the rescuer can pull the person to their side and then rotate and adjust the two floats to form a V-shape. This provides independent buoyancy support for both parties and forms a V-shaped guide vane to reduce the impact of lateral water flow, significantly improving the safety and reliability of mutual rescue in the water.
[0035] Please refer to Figures 1 to 4 A portable water rescue and lifesaving float, comprising a strip-shaped float body 100;
[0036] The float body 100 consists of two floats placed side by side;
[0037] One end of each float body 100 is fixed with a turntable 200, and the central axes of the two turntables 200 are placed in parallel.
[0038] Each turntable 200 is rotatably connected to a rotating shaft 300 placed on the same axis.
[0039] The upper ends of the two rotating shafts 300 are connected to the housing 400, and the rotating shafts 300 are fixedly connected to the housing 400.
[0040] A locking component 500 is provided between the housing 400 and the two turntables 200. The locking component 500 is used to lock or release the rotation of the turntable 200.
[0041] This application utilizes a deployable double float body 100 structure design, enabling the life-saving float to flexibly adjust its shape according to rescue needs, especially showing significant advantages in turbulent water environments. When a long-distance rescue is required, rescuers can quickly rotate and unfold the two float bodies 100 into a straight line, extending the overall length to nearly twice its original length. Rescuers can hold one end and extend the other end towards the person in the water, solving the problem that existing methods of throwing life-saving floats easily cause the life-saving float to be swept away by the water flow, making it easier for the patient to grab it effectively.
[0042] If the person in the water grabs one end of the rescue float, and the rescuer is on shore, they can pull the person back directly. If both the rescuer and the person in the water are in the water, the rescuer can pull the person to their side and then rotate and adjust the two floats to form a V-shape. This provides independent buoyancy support for both parties and forms a V-shaped guide vane to reduce the impact of lateral water flow, significantly improving the safety and reliability of mutual rescue in the water.
[0043] Each locking component 500 includes a slide rod 501 placed coaxially with the turntable 200. The slide rod 501 is slidably connected to the housing 400. A locking block 502 is fixed to the end of the slide rod 501 near the turntable 200. The distance between the housing 400 and the turntable 200 is greater than or equal to the length of the locking block 502 along the axis of the turntable 200.
[0044] Each turntable 200 has a groove 201 on its upper end that matches the card block 502. The groove 201 is a plurality of grooves that are evenly distributed in a ring around the central axis of the corresponding turntable 200.
[0045] When the locking block 502 is inserted into any of the grooves 201, the locking component 500 locks the turntable 200; when the locking block 502 is removed from the groove 201, the turntable 200 and the float body 100 can be rotated and adjusted around the central axis of the rotating shaft 300.
[0046] The upper ends of the slide rods 501 slide through the upper surface of the housing 400, and the upper ends of the slide rods 501 are fixed with handles 503; the handles 503 are provided to facilitate pulling the slide rods 501 and the locking blocks 502 to extend into or move out of the grooves 201.
[0047] The shell 400 is a hollow shell;
[0048] The locking assembly 500 also includes a fixed plate 504 fixedly sleeved on the slide rod 501. The fixed plate 504 is slidably connected inside the housing 400. Each slide rod 501 is sleeved with a spring 505. The lower end of each spring 505 is fixed to the upper end of the fixed plate 504, and the upper end of each spring 505 is fixed to the inner top surface of the housing 400. The spring 505 is used to maintain the stability of the locking block 502 when it is inserted into the groove 201, and to prevent the turntable 200 from deflecting accidentally.
[0049] The slide rod 501 has a groove 506 on its peripheral wall. The groove 506 is placed coaxially with the slide rod 501. The upper shell wall of the housing 400 has a protrusion that matches the groove 506. The matching of the groove 506 and the protrusion improves the guiding performance of the slide rod 501 during movement and prevents the slide rod 501 and the locking block 502 from being misaligned or deflected.
[0050] The upper edge of the groove 201 is provided with a rounded chamfer 202; the rounded chamfer 202 makes the upper end of the groove 201 expand to both sides, so that the locking block 502 can enter the groove 201.
[0051] Each float body 100 is fixed with a handle frame 101 to facilitate grabbing the float body 100 during use.
[0052] Multiple handrail frames 101 are provided on the float body 100 so that the appropriate handrail frame 101 can be selected according to the unfolded state of the two float bodies 100.
