The frisbees on the market have a simple design, just a uniform disc shape, and most of them are made of a single plastic material and integrally injection-molded by an injection molding machine. Such frisbees have poor stability during flight and a short flight distance, and are not suitable for long-distance throwing. Therefore, there is an urgent need for a frisbee to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a frisbee. During the process of throwing the frisbee, the air flow is broken by the disc ring part, and the air flow on the surface of the frisbee is more stable, solving the problem of poor stability of the frisbee during flight, flying farther and being easier to control.

[0022] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] A frisbee, as Figure 1 , the frisbee includes a body part 1 and a disk ring part 2.

[0024] The body part 1 includes a disk body 11 and a ring part 12. The ring part 12 is arranged around the circular edge of the disk body 11. The disk body 11 and the ring part 12 are integrally formed structures. The disk body 11 is a circular plate-like structure, and the ring part 12 is a curved arc structure. Moreover, the height of the connection part between the disk body 11 and the ring part 12 is greater than the height of the outer edge of the ring part 12. The outer surface of the disk body 11 is flat to ensure the flight effect of the frisbee.

[0025] The body part 1 is located inside the disk ring part 2, that is, the disk ring part 2 is arranged around the circular edge of the ring part 12, and the disk ring part 2 and the body part 1 are integrally formed by injection molding. The disk ring part 2 includes an upper ring part 21 and a lower ring part 22. The body part 1 is integrally formed with the inner circular edge of the upper ring part 21, and the material density of the upper ring part 21 is different from the material density of the lower ring part 22.

[0026] In this embodiment, the disk body 11, the ring part 12, and the upper ring part 21 are injection molded with the same density material through one mold, and then the body part 1 with the upper ring part 21 after injection molding is placed on another mold for injection molding of the lower ring part 22, so as to realize the integral injection molding of the disk ring part 2 and the body part 1 and make the material densities of the upper ring part 21 and the lower ring part 22 different. Or different density materials are injected through different injection ports to realize the synchronous injection molding of the disk body 11, the ring part 12, the upper ring part 21, and the lower ring part 22.

[0027] Those skilled in the art should understand that the material densities of the upper ring part 21 and the ring part 12 can also be different, and even the material densities of the ring part 12 and the body part 1 can be different, and it can be injection molded multiple times through multiple molds.

[0028] Specifically, since the material density of the body part 1 is different from that of the disk ring part 2, and the material density of the upper ring part 21 is different from that of the lower ring part 22, the weight distribution of the frisbee can be adjusted, so that the frisbee can fly more smoothly. At the same time, through the disk ring part 2 with a different material density from that of the body part 1, the angular momentum and linear momentum of the frisbee during flight are adjusted, improving the user's control over the flight speed and flight distance of the frisbee. Thus, different density combinations of the materials of the disk body 11, the circular ring part 12, the upper ring part 21, and the lower ring part 22 can enable this frisbee to achieve different flight effects.

[0029] Optionally, the ratio of the material density of the upper ring part 21 to the material density of the lower ring part 22 is greater than or equal to 0.5 and less than 1. When the material density of the upper ring part 21 is the same as that of the body part 1, that is, the overall material density of the disk ring part 2 is greater than that of the body part 1, this can increase the angular momentum and linear momentum of this frisbee during flight. And a higher angular velocity can enable this frisbee to have the ability to maintain a more persistent flight state, thereby enabling this frisbee to fly farther, straighter, and more accurately. At the same time, the material density of the upper ring part 21 is less than that of the lower ring part 22, which can further adjust the weight distribution of the frisbee and improve the stability of the frisbee during flight.

[0030] Optionally, the ratio of the material density of the upper ring part 21 to the material density of the lower ring part 22 is greater than 1 and less than or equal to 2. When the material density of the upper ring part 21 is the same as that of the body part 1, that is, the overall material density of the disk ring part 2 is less than that of the body part 1, this can reduce the angular momentum and linear momentum of this frisbee during flight. And when the user throws this frisbee, the flight speed is reduced under the stable rotation of this frisbee. In this way, it is convenient to give the user a larger force application range, enabling this frisbee to fly more accurately towards the target.

[0031] In this embodiment, the materials of the disk body 11, the circular ring part 12, the upper ring part 21, and the lower ring part 22 can be thermoplastic polyurethane elastomer rubbers with different densities.

[0032] In order to improve the connection strength at the joints of different density materials when manufacturing the frisbee, in this embodiment, the upper ring part 21 has a first groove and / or a second protrusion 211, and the lower ring part 22 has a first protrusion 221 and / or a second groove. The first protrusion 221 is embedded in the first groove, and / or the second protrusion 211 is embedded in the second groove.

[0033] Those skilled in the art should understand that in order to ensure demolding, the notch of the first groove and / or the second groove should be greater than or equal to the bottom of the groove. But in order to further increase the connection strength, such as Figure 2, the first groove and the second groove can be set at a certain angle with the disc body 11, that is, the distance from the bottom of the groove to the axis of the disc body 11 is less than the distance from the notch of the groove to the axis. With such a design, the second protrusion 211 on the upper part 21 of the ring or the first protrusion 221 on the lower part 22 of the ring is in a hook shape and is hooked in the corresponding second groove or first groove, thereby increasing the connection strength.

[0034] In this embodiment, the upper end surface of the disc ring part 2 and the disc body 11 is in a smooth transition. The disc ring part 2 only protrudes downward from the disc body 11. The disc body 11 and the disc ring part 2 enclose a third groove below the disc body 11. It can be understood that the side of the disc body 11 facing away from the third groove is flat, and correspondingly, the side of the disc body 11 located in the third groove is also flat, which is convenient for processing and production.

[0035] Optionally, the side of the disc body 11 located in the third groove can also be a convex arc surface, so that the frisbee has a different flight effect.

[0036] It can be understood that when throwing the frisbee, throw the frisbee with the side of the third groove facing downward. The third groove can accommodate a certain amount of air, so that the frisbee has a longer hang time during flight.

[0037] In an embodiment of the present utility model, the side of the disc ring part 2 facing away from the body part 1 has a first transition surface 23 and a second transition surface 24. The first transition surface 23 is connected to the upper end surface of the ring part 12, and the first transition surface 23 and the second transition surface 24 gradually approach and are connected in the direction away from the body part 1.

[0038] In this embodiment, the outer edges of the first transition surface 23 and the second transition surface 24 are connected. That is to say, the side of the disc ring part 2 adjacent to the body part 1 is thicker, and its outer edge is thinner, that is, the outer edge of the disc ring part 2 is sharper, which is beneficial for the frisbee to break through the air and fly farther.

[0039] In an embodiment of the present utility model, the first transition surface 23 is an upwardly convex arc surface. It can be understood that in this way, the air flow can better flow from the arc of the first transition surface 23 to the arc surface 25 of the ring part 12.

[0040] In an embodiment of the present utility model, the second transition surface 24 faces downward and is a concave arc surface or a convex arc surface facing downward. The second transition surface 24 can be made into a convex or concave arc surface according to different production molds, so that the frisbee achieves different flight effects. It can be understood that when the second transition surface 24 is a convex arc surface, the air flow can better conform to the second transition surface 24 and flow, that is, the air resistance is reduced, and under the same throwing conditions, the frisbee flies faster. When the second transition surface 24 is a concave arc surface, the air flow flows along the second transition surface 24 and towards the lower part of the frisbee, so that the frisbee has a certain floating force and better hang ability.
