[0017] The following describes the specific embodiment, structure, features and effects of the telescopic rescue device according to the present application in detail with reference to the drawings and preferred embodiments.
[0018] Referring to Figures 1 to 5 The telescopic rescue device comprises a shell, a telescopic device and a wing device.
[0019] The telescopic device is connected to the carrier (9) and the control console (1) and is used for power output and boat body expansion.
[0020] The wing device is connected to the telescopic device and the carrier (9) and is used for placing the telescopic oar device and providing a human space and increasing the supportable weight.
[0021] The telescopic oar device is placed on the wing device and is used for rescue assistance.
[0022] The telescopic device and the wing device are located on the carrier (9).
[0023] The multi-branch rotating shaft (11) of the telescopic device is connected to the carrier (9) and the control console (1);
[0024] The connecting rod A connects the multi-branch rotating shaft, passes through the stud bolt and the nut A, is fixed by the nut B, and is connected to the wing; the connecting rod B (16) connects the wing and the hollow circle, the hollow circle is fixed with the spring A (15), is connected to the chuck (14), and the hollow circle is fixed on the carrier of the shell and is used for expanding the boat body space.
[0025] The telescopic oar mainly comprises the oar top (4), the oar middle (5) and the oar tail (6); the oar tail (6) and the oar top are each fixed with the anti-stuck hole round sheet (21), the oar middle is fixed with the boss disc (19) at both ends, the boss disc (19) is provided with the spring B (20), the disc is placed with the buckle spring sheet (18) behind, and the oar is placed on the wing (3) of the wing device, and rescue assistance is performed
[0026] The wing device comprises the wing (3) and the gas storage bag (7) and is used for increasing the supportable weight.
[0027] Step one: the auxiliary rod (2) is rotated clockwise, the connecting rod B (16) is driven to rotate around the hollow circle (8) to the connecting chuck (14) through the adapter (22), and the spring A (15) pushes the connecting chuck (14) to fix the connecting rod B;
[0028] Step 2: After Step 1 is completed, the multi-branch shaft (11) rotates, driving the connecting rod A (12). The connecting rod A (12) pushes the wing (3) to rotate around the connecting rod B, forming a simple four-bar linkage motion state. The multi-branch shaft stops after rotating to a certain angle, and the wing is in an unfolded state.
[0029] Step 3: Remove the retractable oar from the wing.
[0030] Step 4: Press the control lever (17). The control lever presses down the locking spring (18), and the locking spring removes its restriction on the top (4) and tail (6) of the paddle. The spring B (20) on the boss disc (19) pushes the anti-jamming hole disc (21), causing the top and tail of the paddle to move away from the middle (5) of the paddle and unfold. After unfolding to a certain length, the protruding part of the locking spring locks into the round hole at the top and tail of the paddle, thus fixing the length.
[0031] Once deployed, the device can be reset by manually removing the restrictions, while the oars can be reset by applying opposing forces to their top and stern.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
