Description

Technical Field

[0001] This invention relates to the field of marine life-saving equipment technology, and in particular to a pneumatically controlled multi-precision life-saving flying disc. Background Technology

[0002] A rescue disc is a portable and easy-to-use lifesaving device commonly used in maritime rescue or swimming training. It is lightweight, portable, and simple to use, effectively helping drowning victims stay afloat and providing valuable time for waiting for rescue or self-rescue.

[0003] The main components of a rescue frisbee include the frisbee itself and the safety rope. The frisbee itself is typically made of lightweight, durable ABS engineering plastic, while the safety rope, which is 40 meters long and attached to the frisbee, is fixed to the frisbee.

[0004] When using a rescue disc, rescuers should first check that the disc and safety rope are intact. Then, holding the disc, they should throw it towards the drowning person with appropriate force. Once the disc is thrown, the rescuer should immediately grab one end of the safety rope and slowly release it so the drowning person can grab it and stay afloat. After the drowning person grabs the disc, the rescuer can help them secure it to their body to increase buoyancy and stability, and use the safety rope to pull the person to shore or await further rescue.

[0005] However, traditional manual throwing methods not only require high strength from the user, but also have low throwing accuracy and limited operational stability. Summary of the Invention

[0006] The technical problem to be solved by this invention is that the traditional manual throwing method of rescue frisbee not only requires high strength from the user, but also has low throwing accuracy and limited operational stability.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a pneumatically controlled multi-precision rescue frisbee, including a ring handle assembly and a frisbee body. A main assembly plate is movably installed on the outer side of the ring handle assembly through an assembly frame. An upper storage slot for storing the frisbee body is opened at the upper end of the main assembly plate. Piston-type lateral limiting blocks are elastically assembled on the inner walls of the upper storage slot on both sides of the lateral opening. An arc-shaped ejection seat is installed on the arc-shaped surface inside the upper storage slot. An embedded press-inflatable airbag is installed at the bottom of the main assembly plate.

[0008] The lower end of the main assembly plate is located on both sides of the embedded press-to-inflate airbag, and a bottom assembly frame for installing the ring handle assembly is fixed thereon.

[0009] The ring handle assembly includes an outer grip ring that is movably inserted into the bottom mounting frame on one side of the embedded press-to-inflate airbag, an inner grip ring that is movably inserted into the bottom mounting frame on the other side of the embedded press-to-inflate airbag, and a pull cord.

[0010] The main assembly plate has an internal air storage chamber located outside the upper storage slot.

[0011] The upper storage slot has lateral telescopic grooves protruding into the interior of the built-in air storage chamber on the inner walls of both sides of the lateral opening, and an arc-shaped telescopic groove for storing the arc-shaped ejector seat is opened on the inner side of the upper storage slot.

[0012] The piston-type lateral limiting block includes an adjusting slider inserted into the lateral telescopic groove, an arc-shaped limiting block fixed on the outer surface of the adjusting slider, and an external compression spring installed on the outer surface of the adjusting slider.

[0013] The arc-shaped ejection seat includes an arc-shaped ejection back plate located in an arc-shaped telescopic groove, an internal piston rod fixedly installed on the back of the arc-shaped ejection back plate, and an end limiting plate axially fixed to the end of the internal piston rod.

[0014] The bottom of the main assembly plate is provided with a circular mounting groove, and the inner side of the circular mounting groove is provided with an internal guide hole that communicates with the built-in air storage chamber.

[0015] The embedded press-to-inflate airbag has a first check valve fixed at the connection end of the internal guide hole, and a second check valve fixed on the side wall of the embedded press-to-inflate airbag.

[0016] LED lights for directional lighting are fixedly mounted on both sides of the arc-shaped surface of the main assembly plate at the opening end of the upper storage slot.

[0017] The beneficial effects of this invention are: (1) The pneumatically controlled multi-precision life-saving flying disc of the present invention can improve the structural stability in the gripping state by adopting a double grip ring design; (2) By providing an upper storage slot for storing the frisbee body at the upper end of the main assembly plate, the structural stability in the stored state can be improved. (3) The entire frisbee is in a close-fitting state when stored, which greatly reduces the external space occupied and makes it easy to store; (4) An internal air storage chamber is provided inside the main assembly plate. The piston-type lateral limiting block and the arc-shaped ejection seat are driven by the high-pressure air inside. It can not only limit the frisbee body in the upper storage slot when it is inflated, but also quickly eject the frisbee body when it is deflated. The pneumatic ejection method replaces manual throwing, which is more labor-saving and accurate. (5) An embedded press-inflatable airbag is installed at the bottom of the main assembly plate, which not only does not take up the space at the bottom, but also makes the operation more convenient; (6) The entire driving method uses the potential energy generated by high-pressure air and spring to drive the arc-shaped catapult seat, which can greatly improve the projection range of the flying disc.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Figure 1 , Figure 2 , Figure 3 and Figure 4 The pneumatically controlled multi-precision rescue frisbee shown includes a ring handle assembly and a frisbee body 1. A main assembly plate 2 is movably mounted on the outer side of the ring handle assembly via an assembly frame. The upper end of the main assembly plate 2 has an upper storage slot 3 for storing the frisbee body 1. Piston-type lateral limiting blocks 4 are elastically mounted on the inner walls of the upper storage slot 3 on both sides of the lateral opening. An arc-shaped ejection seat 5 is installed on the inner arc-shaped surface of the upper storage slot 3. An embedded press-inflatable airbag 6 is installed at the bottom of the main assembly plate 2.

[0026] Operation method: When using, flip the ring handle assembly downwards, then hold the ring handle assembly with your hand, and inflate the inside by pressing the embedded airbag 6. Then, project the frisbee body 1 outwards along the side opening of the upper storage slot 3 through the arc spring seat 5.

[0027] To accommodate the bottom assembly, the lower end of the main assembly plate 2 is fixed with bottom assembly frames 7 for mounting the ring handle assembly on both sides of the embedded press-to-inflate airbag 6.

[0028] To facilitate gripping, the ring handle assembly includes an outer grip ring 8 that is movably inserted into the bottom mounting frame on one side of the embedded press-inflatable airbag 6, an inner grip ring 9 that is movably inserted into the bottom mounting frame on the other side of the embedded press-inflatable airbag 6, and a pull cord 10.

[0029] The outer grip ring 8 and the inner grip ring 9 are flipped downwards to form a V-shaped grip support at the bottom of the main assembly plate 2, which makes the grip stability better, maintains the stability of the projectile process, and thus improves the accuracy.

[0030] When not in use, the pull rope 10 is wrapped around the outside of the main assembly plate 2. The external threaded connectors at both ends of the pull rope 10 can be fixedly assembled with the internal threaded mounting holes on the arc-shaped surface of the flying disc body 1 and the main assembly plate 2, respectively.

[0031] To accommodate the internal high-pressure air filling, the main assembly plate 2 has an internal air storage chamber 11 located around the upper storage slot 3.

[0032] To facilitate lateral assembly, the upper storage slot 3 has lateral telescopic grooves 12 protruding into the interior air storage chamber 11 on the inner walls on both sides of the lateral opening, and an arc-shaped telescopic groove 13 for accommodating the arc-shaped ejector seat 5 is provided on the inner side of the upper storage slot 3.

[0033] To facilitate elastic compression and reset, the piston-type lateral limiting block 4 includes an adjusting slider 41 inserted into the lateral telescopic groove 12, an arc-shaped limiting block 42 fixed on the outer surface of the adjusting slider 41, and an external compression spring 43 installed on the outer surface of the adjusting slider 41.

[0034] Inside the outer opening of the lateral telescopic groove 12, there is an opening limiting frame for the limiting adjustment slider 41 and the external compression spring 43. The outer end of the external compression spring 43 presses against the inner wall of the opening limiting frame, thereby pressing the adjusting slider 41 inward. Once the air is released inside the built-in air storage chamber 11, the external compression spring 43 will press the adjusting slider 41 inward, thereby causing the arc-shaped limiting block 42 to separate from both sides of the frisbee body 1, and the frisbee body 1 can be quickly shot out.

[0035] To facilitate ejection control, the arc-shaped ejection seat 5 includes an arc-shaped ejection back plate 51 located within the arc-shaped telescopic groove 13, an internal piston rod 52 fixedly installed on the back of the arc-shaped ejection back plate 51, and an end limiting plate 53 axially fixed to the end of the internal piston rod 52.

[0036] An inner elastic buckle for limiting the end limiting plate 53 is elastically fitted inside the built-in air storage chamber 11. It is controlled by a pull rod located inside the main assembly plate 2. When people pull the pull rod outward, the inner elastic buckle can be separated from the end limiting plate 53. In this way, the pressure inside the built-in air storage chamber 11 will drive the end limiting plate 53 and the internal piston rod 52 to squeeze outward, thereby controlling the arc-shaped ejection back plate 51 to squeeze the flying disc body 1 and quickly launch the flying disc body 1.

[0037] To facilitate bottom mounting and airflow guidance, a circular mounting groove is provided at the bottom of the main assembly plate 2, and an internal airflow guide hole 14 is provided on the inner side of the circular mounting groove, which is connected to the built-in air storage chamber 11.

[0038] For easy inflation, the embedded press-to-inflate airbag 6 has a first check valve 15 fixed at the connection end of the internal guide hole 14, and a second check valve 16 fixed on the side wall of the embedded press-to-inflate airbag 6.

[0039] The function of the first check valve 15 is to unidirectionally squeeze the air inside the embedded press-to-inflate airbag 6 into the internal guide hole 14, while the second check valve 16 is used to unidirectionally draw the air from the outside into the embedded press-to-inflate airbag 6.

[0040] To improve directionality and ensure employee stability in low-light conditions, LED lights 17 for directional lighting are fixedly mounted on both sides of the opening end of the upper storage slot 3 on the arc-shaped surface of the main assembly plate 2.

[0041] The LED light 17 can illuminate the launch point, and the LED light 17 can also be controlled to flash to emit a warning light by pressing the hand switch on the main assembly plate 2.

[0042] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
