[0026] See attached document Figure 1-2 This application provides a detailed description of a rescue oar provided in its embodiments, wherein... Figure 1 A schematic diagram of one embodiment of a rescue paddle provided in this application; Figure 2 A schematic diagram of a mounting structure for a rescue oar provided in this application; Figure 3 This is a schematic diagram of another embodiment of a rescue paddle provided in this application.
[0027] like Figure 1 As shown, this application provides a rescue oar, comprising: an oar shaft 11 and an oar blade 12, wherein the oar shaft is connected to the oar blade, specifically, the end of the oar shaft 11 is inserted into the oar blade 12 and is detachably connected to the oar blade 12; the oar shaft 11 includes a fixed rod 111 and a movable rod, the fixed rod 111 being sleeved on the outside of the movable rod, the movable rod being a telescopic rod 112, the telescopic rod 112 including one or more inner rods; the end of the movable rod away from the oar blade 12 (e.g., the end of the fixed rod away from the oar blade 12) Figure 1A float ring 13 is provided at the upper end of the movable rod, which floats when placed in a liquid. A fixing seat 114 is provided on the fixed rod 111 to fix the float ring 13 when the telescopic rod is in the retracted position, thereby fixing the movable rod. The fixed rod 111 and the movable rod are fixedly connected by fixing the float ring 13 through the fixing seat 114. The telescopic rod has an extended position and a retracted position. When the telescopic rod is in the extended position, that is, when the telescopic rod is retracted into the fixed rod, the float ring can be fixed to the fixed rod through the fixing seat, thereby fixing the telescopic rod inside the fixed rod and keeping the telescopic rod in the extended position. When the telescopic rod is in the extended position, that is, when the telescopic rod extends out from the fixed rod, the length of the paddle rod increases.
[0028] The present application provides a rescue paddle with a telescopic rod 112, which can rescue people who have fallen into the water over long distances. It adopts a floating ring 13 design to make it easy for people who have fallen into the water to grab, so that the rescue can be carried out quickly and conveniently.
[0029] The propeller shaft 11 and blade 12 are both made of insulating material. Preferably, the propeller shaft 11 and blade 12 are made of carbon fiber material.
[0030] It should be noted that multiple inner rods, such as the first inner rod, the second inner rod, the third inner rod, ... the nth inner rod, where n is a natural number greater than 1, are preferably arranged coaxially. The fixing rod 111 is sleeved on the outside of the first inner rod, the first inner rod is sleeved on the outside of the second inner rod, the second inner rod is sleeved on the outside of the third inner rod, and so on, with the (n-1)th inner rod sleeved on the outside of the nth inner rod.
[0031] In one specific embodiment, the outer diameter of the end of each inner rod furthest from the blade 12 is smaller than the outer diameter of the end of the inner rod closest to the blade, thus ensuring a fixed connection between the outer tube and the inner tube when the telescopic rod is in the extended position. It should be noted that the fixing rod 111 is the outer tube relative to the first inner rod, and the first inner rod is the inner tube; the first inner rod is the outer tube relative to the second inner rod, and the second inner rod is the inner tube, and so on, with the (n-1)th rod being the outer tube relative to the nth inner rod, and the nth inner rod being the inner tube. In use, the inner tube is unfolded. Because the outer diameter of the end of the inner tube closest to the blade is larger than the outer diameter of the end furthest from the blade, the other end of the inner tube is easily fixed to the outer tube. The structure is simple, requiring no additional components to fix the inner and outer tubes, making operation convenient. After use, the inner tube is forcefully retracted towards the outer tube, making operation simple and convenient.
[0032] In one specific embodiment, to enhance the locking effect of the inner and outer tubes, a fixing component 115 is provided at the end of the fixing rod 111 away from the blade 12 and at the end of each inner rod away from the blade 12. This component is used to fix each inner rod after it has extended, and can also be used to fix the fixing seat, providing a limiting effect. Specifically, a first fixing component is provided at one end of the fixing rod 111 to fix the first inner rod; a second fixing component is provided at one end of the first inner rod to fix the second inner rod; a third fixing component is provided at one end of the second inner rod to fix the third inner rod; and so on, with an nth fixing component provided at one end of the (n-1)th inner rod to fix the nth inner rod. Using the fixing component 115 greatly enhances the connection strength and locking effect between the outer and inner tubes, protecting both the inner and outer tubes and preventing breakage at the fixed connection point during use.
[0033] One feasible design for the fixing component 115 is a retaining ring. Specifically, a first retaining ring is provided at one end of the fixing rod 111 to fix the first inner rod. The inner diameter of the first retaining ring is slightly smaller than the inner diameter of the fixing rod 111, thus fixing the end of the first inner rod near the blade 12 to one end of the fixing rod 111. A second retaining ring is provided at one end of the first inner rod to fix the second inner rod. The inner diameter of the second retaining ring is slightly smaller than the inner diameter of the first inner rod, thus fixing the end of the second inner rod near the blade 12 to one end of the first inner rod. Similarly, an nth retaining ring is provided at one end of the (n-1)th inner rod to fix the nth inner rod. The inner diameter of the nth retaining ring is slightly smaller than the inner diameter of the (n-1)th inner rod, thus fixing the end of the nth inner rod near the blade 12 to one end of the (n-1)th inner rod. The retaining ring significantly strengthens the connection strength and locking effect between the outer and inner tubes, protecting both the inner and outer tubes and preventing breakage at the fixed connection point during use.
[0034] One feasible design for the fixing component 115 is an eccentric device. The telescopic rod 112 is fixed by the eccentric device. The inner and outer tubes rotate relative to each other, and the eccentric device will squeeze the inner wall of the outer tube to achieve the locking function. Specifically, a first eccentric device is provided at one end of the fixed rod 111 to fix the first inner rod. The fixed rod 111 and the first inner rod rotate relative to each other. The first eccentric device presses against the inner wall of the fixed rod 111, thereby fixing the other end of the first inner rod near the blade 12 to one end of the fixed rod 111. A second eccentric device is provided at one end of the first inner rod to fix the second inner rod. The first inner rod and the second inner rod rotate relative to each other. The second eccentric device presses against the inner wall of the first inner rod, thereby fixing the other end of the second inner rod near the blade 12 to one end of the first inner rod. And so on, an nth eccentric device is provided at one end of the (n-1)th inner rod to fix the nth inner rod. The (n-1)th inner rod and the nth inner rod rotate relative to each other. The nth eccentric device presses against the inner wall of the (n-1)th inner rod, thereby fixing the other end of the nth inner rod near the blade 12 to one end of the (n-1)th inner rod. The eccentric device greatly enhances the connection strength and locking effect between the outer and inner tubes, protecting both the inner and outer tubes and preventing breakage at the fixed connection point during use.
[0035] One feasible design for the fixing component 115 is a snap-fit device, in which a protrusion is provided on one of the inner tube and the outer tube, and a groove or hole is provided on the other. When the inner tube is unfolded, the inner tube and the outer tube are snap-fitted and fixed. The protrusion can also be designed as an elastic protrusion to facilitate installation and disassembly. When the inner tube is unfolded, the protrusion is inserted into the groove or hole, and the inner tube can be retracted by removing the protrusion from the groove or hole. Specifically, one of the fixing rod and the first inner rod is provided with a protrusion, and the other is provided with a groove or hole. When the first inner rod is unfolded, the fixing ring and the first inner rod are snap-fitted and fixed. One of the first inner rod and the second inner rod is provided with a protrusion, and the other is provided with a groove or hole. When the second inner rod is unfolded, the first inner rod and the second inner rod are snap-fitted and fixed. And so on, one of the (n-1)th inner rod and the nth inner rod is provided with a protrusion, and the other is provided with a groove or hole. When the nth inner rod is unfolded, the (n-1)th inner rod and the nth inner rod are snap-fitted and fixed. The snap-fit design greatly enhances the connection strength and locking effect between the outer and inner tubes, protecting both the inner and outer tubes and preventing breakage at the fixed connection point during use.
[0036] The paddle shaft 11 has a tubular structure for easy operation; the paddle blade 12 has a plate-like structure for paddling; one end of the paddle shaft 11 is provided with a connector 113, and the outer contour of the other end of the paddle shaft 11 is a conical structure for easy installation; the paddle blade 12 is located at the conical end of the paddle shaft 11, and the middle position of the paddle blade 12 is connected to the outer wall of the paddle shaft 11.
[0037] The fixed rod 111 and the movable rod are coaxially arranged. One end of the fixed rod 111 has a tubular structure, and the outer contour of the other end of the fixed rod 111 near the blade 12 is a conical structure. In one specific embodiment, the conical structure at the other end of the fixed rod 111 is inserted into the blade 12 and detachably connected to the blade 12. In another specific embodiment, in order to connect the fixed rod 111 and the blade 12 more tightly, the conical structure and part of the tubular structure at the other end of the fixed rod 111 are inserted into the blade 12, making the detachable connection with the blade 12 more secure. The tubular structure at one end of the fixed rod is for easy gripping and use by the operator, while the conical structure at the other end facilitates insertion into the blade 12.
[0038] The blade 12 has a groove in the middle for mounting the blade rod 11, and is detachably connected to the blade rod 11. The shape of the groove matches the part of the fixing rod 111 that inserts into the blade; that is, the groove can be an inner conical structure for mounting the conical structure at one end of the fixing rod 111; or it can be a combination of an inner conical structure and an inner cylindrical structure for mounting the conical structure at one end of the fixing rod 111 and a part of the tubular structure. The groove on the blade is designed in the same way as the other end of the fixing rod, for the convenience and speed of the operator.
[0039] In one specific embodiment, the groove is provided with one or more liquid guiding holes 116, wherein there are 2, 3, 4, 5, or 6 such holes. The liquid guiding holes 116 can be located in the center of the groove and are used to introduce adhesive to bond and fix the fixing rod 111 and the blade 12. Using multiple liquid guiding holes 116 to introduce the adhesive results in a more uniform fixing position and a significantly better fixing effect than using a single liquid guiding hole 116. In a top view, the shape of the liquid guiding hole can be circular, elliptical, arc-shaped, or polygonal; the polygonal shape can be triangular, rectangular, trapezoidal, pentagonal, hexagonal, etc.
[0040] like Figure 1 As shown in the top view, in one specific embodiment, the blade 12 comprises a triangle and a rectangle; one of the shorter sides of the rectangle is the base of the triangle, and the fixing rod 111 is inserted into the blade 12 from the apex of the triangle away from the rectangle; the two corners of the rectangle away from the triangle have rounded corners to reduce water resistance during use. In another specific example, the blade 12 comprises a triangle and a trapezoid, preferably an isosceles trapezoid; the shorter side of the trapezoid is the base of the triangle, and the fixing rod 111 is inserted into the blade 12 from the apex of the triangle away from the trapezoid; the two corners of the trapezoid away from the triangle have rounded corners to reduce water resistance during use and for aesthetic purposes. In one specific embodiment, the blade 12 is integrally formed with the fixing rod 111 of the paddle shaft 11. The blade 12 has an aesthetically pleasing design, strong paddling force, and facilitates speed increase for the operator.
[0041] A connector 113 is provided at one end of the paddle rod 11, that is, the end of the movable rod away from the paddle blade 12. In other words, a connector 113 is provided at one end of the innermost nth rod. The connector 113 is provided with a through hole, and a float ring 13 is installed in the through hole. The float ring is provided for rescue, especially for people who have fallen into the water. People who cannot swim will grab around randomly after falling into the water, which will affect the rescuers. By deploying the float ring, whose position can be controlled by the paddle, people who have fallen into the water can grab it quickly and save their lives.
[0042] The inner core of the float ring 13 is made of a high-strength metal material, such as iron wire, steel wire, titanium alloy, aluminum alloy, or magnesium alloy, to increase the strength of the float ring 13. Taking steel wire as an example, a first sleeve is fitted over the inner core to protect it and prevent friction against the second sleeve. The first sleeve can be made of a lightweight material that floats in water, such as a plastic tube or rubber tube. For easy observation of the inner core, the first sleeve can be made of a transparent material (e.g., a transparent plastic tube). A second sleeve is fitted over the first sleeve. The second sleeve can also be made of a lightweight material that floats in water. Preferably, the second sleeve is made of closed-cell foam, which has high buoyancy and floats on the water surface, facilitating rescue of drowning victims and making it easy for them to grab onto the float. The material selection of the float ring ensures that the product possesses both strength and buoyancy, significantly improving rescue effectiveness.
[0043] like Figure 2 As shown, in one specific embodiment, a fixing seat 114 may be provided at the end of the fixing rod 111 away from the blade 12 for fixing the floating ring 13, and thus fixing the telescopic rod 112; in one specific embodiment, the fixing seat 114 is located at the end of the fixing component 115 near the blade 12. The fixing seat 114 includes a protrusion 1141 and a fixing strap 1142. The fixing strap 1142 can be arranged circumferentially along the fixing rod 111. The fixing strap 1142 is elastic and belongs to elastic components, such as rubber bands, elastic bandages, elastic belts, etc. In a specific embodiment, the fixing strap 1142 is an elastic band. One or more fixing holes that cooperate with the protrusion are arranged along the length direction of the fixing strap 1142, with a plurality of holes being 2, 3, 4, 5, 6, 7, 8, or 9. The fixing strap 1142 is attached to the outside of the float ring 13. Utilizing the elasticity of the fixing strap 1142, the fixing strap 1142 is stretched taut. By inserting the protrusion 1141 into one of the fixing holes of the fixing strap 1142, the float ring 13 is fixed inside the fixing strap 1142, thereby fixing all the inner rods of the telescopic rod 112. The design of the fixing seat in this application is simple in structure, saves space when set on the fixing rod 111, and simultaneously fixes all the inner rods and the float ring, making it efficient and convenient.
[0044] In one specific embodiment, an escape hammer or window breaker 117 may be provided at the end of the connector 113 away from the blade 12 for breaking objects to escape safely. For example, in a car, people can use the escape hammer or window breaker 117 to break the glass and escape from the vehicle. The escape hammer or window breaker 117 is included in this application to break obstacles during escape and open another route for rescue. The escape hammer or window breaker 117 is made of a metal material, such as stainless steel; preferably, it is made of titanium alloy.
[0045] like Figure 3 As shown, in one specific embodiment, to increase the buoyancy of the float ring 13, the outer diameter of the float ring 13 can be larger than the diameter of the through hole of the connector 113. That is, the outer diameter of the second sleeve is larger than the diameter of the through hole. The purpose of this design is to make the float ring 13 larger, making it easier for a person falling into the water to grip, thereby generating greater buoyancy to help the person escape more quickly. Of course, the outer diameter of the float ring 13 can also be smaller than the diameter of the through hole of the connector 113, i.e., the outer diameter of the second sleeve is smaller than the diameter of the through hole, allowing the float ring 13 to move freely within the through hole, facilitating its installation. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features of the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.
[0046] For those skilled in the art, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. It is obvious that this invention is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, all embodiments are merely illustrative and not exhaustive, and should be considered exemplary and non-limiting. The scope of this invention is defined by the appended claims rather than the foregoing description, and therefore all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims. All changes within the scope of this invention or its equivalents are included in this invention.
