[0002] The lionfish's entire body is covered by broad fins, resembling a straw raincoat, hence its name. When it slowly spreads its large pectoral fins, they resemble the majestic mane of a lion's neck. The lionfish has earned the nickname "lionfish" thanks to its highly recognizable appearance, making it one of the most visually appealing marine creatures. However, currently, there are no commercially available mechanical structures that can simulate the lionfish's fin-spreading and retracting movements. Utility Model Content

[0003] The purpose of this invention is to provide a device that can simulate the fins of a lionfish in order to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figure 1-3 As shown, this embodiment discloses a device that can simulate the fins of a lionfish, comprising:

[0027] The fish body frame 1 is made of several rectangular tubes in the shape of a fish body, including a first vertical rod 2, a second vertical rod 3, a third vertical rod 4, a first mounting ring 5 and a second mounting ring 6 arranged sequentially from the tail to the head, and a through hole 7 is provided in the middle of the second vertical rod 3;

[0028] A pair of guide rods 8 are disposed between the second vertical rod 3 and the third vertical rod 4, and the two guide rods 8 are arranged vertically.

[0029] Slide plate 9 is slidably connected to guide rod 8;

[0030] A drive motor 10 is mounted on the first vertical rod 2. It is a servo motor that can rotate in both directions to achieve reciprocating motion. Its output end is connected to the slide plate 9 through a push rod 11. The push rod 11 passes through the through hole 7. The first vertical rod 2, the second vertical rod 3, and the third vertical rod 4 are mounted on the same vertical plane. A through hole 7 is opened on the second vertical rod 3 to facilitate the passage of the push rod 11 and avoid obstruction.

[0031] The fin rod 12 is circumferentially and evenly rotatably connected to the middle part of several fin rods 12 by the first mounting ring 5 and the second mounting ring 6. In this embodiment, the fin rod 12 adopts a V-shaped structure, and the middle part of the fin rod 12 is the bend of the V-shaped structure. One end of the fin rod 12 is rotatably connected to the first connecting rod 13, and the other end of the first connecting rod 13 is rotatably connected to the slide plate 9.

[0032] The usage principle and operation process of this embodiment are as follows:

[0033] The user starts the drive motor 10, and the output of the drive motor 10 drives the push rod 11 to move back and forth, thereby pushing the slide plate 9 to reciprocate on the guide rod 8. When the slide plate 9 moves towards the head of the fish body frame 1, the first connecting rod 13 pushes the end of the fin rod 12 connected to it to rotate towards the head, and the other end of the fin rod 12 to rotate towards the tail, thereby simulating the contraction of the lionfish's fins. When the slide plate 9 moves towards the tail of the fish body frame 1, the first connecting rod 13 pulls the end of the fin rod 12 connected to it to rotate towards the tail, and the other end of the fin rod 12 to rotate towards the head, thereby simulating the unfolding of the lionfish's fins.

[0034] Example 2

[0035] like Figure 1-3 As shown, this embodiment is developed based on Embodiment 1 to address the connection stability between the slide plate 9 and the motor. Specifically, the slide plate 9 includes a front plate 901 and a rear plate 902, and the edges of the front plate 901 and the rear plate 902 are connected by several evenly arranged second connecting rods 903. By setting the slide plate 9 as a two-layer structure, the stability and load-bearing capacity of the structure can be enhanced.

[0036] Furthermore, the push rod 11 includes a front rod 1101 and a rear rod 1102. One end of the front rod 1101 is connected to the output end of the drive motor 10, and the other end is connected to one end of the rear rod 1102 via a universal joint 1103. The other end of the rear rod 1102 is connected to the rear plate 902. By configuring the push rod 11 into two parts and connecting the two parts with a universal joint 1103, lateral forces on the drive motor 10 due to machining or installation errors can be avoided.

[0037] Furthermore, a sleeve 14 is provided in the middle of the rear rod 1102 near the tail of the fish body frame 1, and one end of the rear rod 1102 near the rear plate 902 is inserted into the sleeve 14. The installation method of inserting the rear rod 1102 into the sleeve 14 can ensure that the installation of the rear rod 1102 is more stable.

[0038] Example 3

[0039] like Figure 1-3 As shown, this embodiment is developed based on Embodiment 1 to address the issue of how the entire device is supported and moved. Specifically, a support member 15 is provided at the bottom of the fish body frame 1. The support member 15 can be a combination of a support rod and a frustum. The top of the support rod is connected to the bottom of the fish body frame 1, and the bottom of the support rod is fixedly mounted on the frustum. The frustum, placed on the ground, can provide stable support for the fish body frame 1.

[0040] Furthermore, the support member 15 is mounted on the base 16, and the bottom of the base 16 is provided with casters 17. By moving the base 16 with the casters 17, the entire structure can be moved, thereby facilitating the repositioning of this utility model.

[0041] Example 4

[0042] like Figure 1-3 As shown, the number of fin rods 12 on both the first mounting ring 5 and the second mounting ring 6 is an even number. The even number of fin rods 12 are symmetrically distributed circumferentially along the mounting rings, ensuring that the number of fins on both sides of the fish body frame 1 is equal, thus simulating the symmetrical structure of the lionfish's pectoral fins.

[0043] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
