[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a lifeboat paddle, including an upper grip 1, a lower grip 3 at the bottom of the upper grip 1, multiple semi-circular grooves 4 on the outer wall of the upper grip 1 and the interior of the lower grip 3, and rotating beads 5 slidably connected inside the multiple semi-circular grooves 4, which can slide up and down inside the semi-circular grooves 4. A fixing ring 6 is fixedly connected to the top of the lower grip 3 to prevent the rotating beads 5 from falling out. A threaded groove 7 is provided at the bottom of the outer wall of the lower grip 3, and a spiral sleeve 8 is threadedly connected to the outer wall of the threaded groove 7 to facilitate the disassembly of the lower grip 3 and the paddle plate 9. The paddle plate 9 is fixedly connected to the outer wall of the spiral sleeve 8. A locking mechanism 2 is provided on the front side of the paddle plate 9 to lock the two paddle plates 201.

[0040] Specifically, the upper grip 1 and the lower grip 3 cooperate, with the lower grip 3 placed at the bottom of the upper grip 1. Multiple semi-circular grooves 4 are correspondingly opened on the outer walls and inside of both, and the rotating ball 5 is embedded in the semi-circular groove 4, which can slide up and down flexibly, effectively reducing the friction between the upper grip 1 and the lower grip 3 during relative movement, so that the upper grip 1 can be retracted into the lower grip 3, reducing the space occupied when placed. The top of the lower grip 3 is fixed to prevent the rotating ball 5 from falling off. The bottom of the outer wall of the lower grip 3 is provided with a threaded groove 7, which is threadedly connected to the spiral sleeve 8. The paddle plate 9 is firmly welded to the outer wall of the spiral sleeve 8.

[0041] Reference Figure 5 The locking mechanism 2 includes two paddle plates 201. The rear sides of the two paddle plates 201 are set on the front side of the paddle plate 9.

The front sides of the two paddle plates 201 are provided with springs 1 205. The front sides of the two springs 1 205 are fixedly connected to springs 206. The front sides of the two springs 206 are fixedly connected to extrusion columns 207. The extrusion columns 207 extrude springs 1 205 through springs 2 206 to extrude round holes 204. Opening the paddle plates 201 increases the levitation area of ​​the paddle plate 9 through the hinges 202.

[0042] Specifically, two paddles 201 are fixed to the front of paddle 9. Hinges 202 are firmly welded to the upper and lower right sides of paddle 201, allowing paddle 201 to open and close flexibly. Circular holes 204 are opened on the front sides of the fixing blocks 203 on both sides of paddle 9. Spring 1 205 and spring 2 206 are built into the front side of paddle 201. The extrusion column 207 connected to the front end can push spring 1 205 out of the circular hole 204 under the elastic force of spring 2 206, so that paddle 201 can be unfolded with the help of hinges 202, effectively increasing the overall suspension area of ​​paddle 9 and improving the stability of water movement.

[0043] Reference Figure 1 and Figure 2 A handle 10 is fixedly connected to the top of the upper grip 1. The handle 10 has a smooth design, making it easy to rotate or pick up the paddle. A slot 11 is opened on the front side of the handle 10. A bolt 12 is threaded inside the slot 11 to fix the handle 10 to the top of the upper grip 1. Multiple anti-slip rings 13 are fixedly connected to the outer wall of the lower grip 3 to increase friction when gripping the lower grip 3. Handles 14 are fixedly connected to the front of both paddleboards 201 to facilitate opening the paddleboards 201.

[0044] Specifically, the top of the upper grip bar 1 is fixed with a handle 10, which has a smooth shape design. Users can easily and conveniently operate the handle 10 when rotating the paddle to adjust the paddling direction or when picking up the paddle to prepare to go into the water. The groove 11 on the front side of the handle 10 is connected to the bolt 12 by thread to fix the handle 10 to the top of the upper grip bar 1, ensuring the stability of the structure. The multiple anti-slip rings 13 on the outer wall of the lower grip bar 3 can significantly increase the friction when the user grips it, preventing the hand from slipping. The handle 14 on the front side of the paddleboard 201 makes it easy to open the paddleboard 201.

[0045] Reference Figure 1 , Figure 3 and Figure 5The top of the fixing ring 6 is provided with a semi-circular groove 15, and a sealing ring 16 is fixedly connected inside the semi-circular groove 15 to prevent water from entering the lower grip 3. Multiple hinges 202 are fixedly connected at equal intervals to the left and right sides of the two paddles 201. The bottom of multiple hinges 202 are fixedly connected at equal intervals to the left and right sides of the paddle 9. The rear sides of the two fixing blocks 203 are fixedly connected at equal intervals to the front side of the paddle 9. The diameter of the two round holes 204 is larger than the diameter of the two springs 205.

[0046] Specifically, a sealing ring 16 is fixed in the semi-circular groove 15 at the top of the fixing ring 6 to block water flow and effectively prevent water from seeping into the lower grip 3, ensuring the normal operation of the internal components. Multiple hinges 202 are arranged in an orderly manner and distributed at equal intervals between adjacent ones, and are fixed on the left and right sides of the two paddles 201. Their bottoms are also connected at equal intervals to the left and right sides of the paddle 9, ensuring smooth and stable opening and closing of the paddles. The two fixing blocks 203 are neatly arranged on the rear side and connected at equal intervals to the front side of the paddle 9. The diameter of the two round holes 204 is larger than the diameter of the spring 205, leaving space for the extension and retraction of the internal spring 205.

[0047] Working principle: The upper grip 1 and lower grip 3 work together. The rotating ball 5 is installed in the multiple semi-circular grooves 4 corresponding to the outer wall and the inside. The rotating ball 5 can slide freely and flexibly up and down in the semi-circular grooves 4. When it is necessary to adjust the length of the paddle or store it, the upper grip 1 can move smoothly relative to the lower grip 3 with the help of the rotating ball 5 to completely retract into the lower grip 3, which greatly reduces the space occupied when placing it, making it convenient for storage and carrying. The fixing ring 6 at the top of the lower grip 3 locks the rotating ball 5 to prevent it from falling off accidentally during use and to ensure the stability of the structure. The threaded groove 7 at the bottom of its outer wall is threadedly connected to the spiral sleeve 8. The paddle plate 9 is welded to the outer wall of the spiral sleeve 8. The user can easily remove or install the paddle plate 9 by rotating the spiral sleeve 8.

[0048] Furthermore, firstly, the paddleboard 201 opens and closes via the hinge 202. A portion of the spring 205 is located within the circular hole 204 on the front side of the fixing block 203, serving a certain positioning and pre-tightening function. When an external force is applied to pull the paddleboard 201 to rotate outward around the hinge 202, the spring 206 is stretched, generating elastic force. Under the continuous push of this elastic force, the extrusion column 207 connected to the front end of the spring 206 begins to move. The extrusion column 207 further pushes the spring 205 outward along the circular hole 204, causing the spring 205 to retract out of the circular hole 204. Then, the paddleboard 201 can be opened, effectively increasing the suspension area of ​​the paddleboard 9, thereby dispersing the force when paddling on the water.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
