Description

Technical Field

[0001] This utility model relates to the field of lantern technology, specifically to the tentacle swinging device of a mechanical jellyfish lantern. Background Technology

[0002] Lanterns, also known as decorative lanterns, are a cultural product of China's traditional agricultural era, combining practical function with artistic features. Lantern exhibitions are typically held during lantern festivals and can be categorized into several types, including craft lanterns, table lanterns, and lantern sets. To attract attention, animals or other shapes are often used to represent the overall image of the lantern. Currently, jellyfish-shaped lanterns are available on the market, but they primarily depict the static form of a jellyfish and fail to simulate the movement of its tentacles, resulting in a somewhat monotonous visual experience.

[0022] 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.

[0023] Example 1

[0024] like Figure 1-6 As shown, this embodiment discloses a tentacle swinging device for a mechanical jellyfish lantern, including a column 1. An umbrella-shaped mounting base 2 is provided at the top of the column 1, providing mounting support for the umbrella-shaped mounting base 2. The umbrella-shaped mounting base 2 provides mounting support for a hemispherical lampshade to simulate the umbrella shape of a jellyfish. A driving mechanism 3 is provided on the upper surface of the umbrella-shaped mounting base 2. The driving shaft 301 of the driving mechanism 3 extends downward into the interior of the umbrella-shaped mounting base 2. A first gear 4 is sleeved on the driving shaft 301. Several transmission gear sets 5 are provided inside the umbrella-shaped mounting base 2, evenly distributed around the circumference of the first gear 4. The first gear 4 meshes with the several transmission gear sets 5. The transmission shaft 501 of the transmission gear sets 5 extends out from the bottom of the umbrella-shaped mounting base 2 and is connected to a turntable 6. A light strip is connected to the bottom of the turntable 6 to simulate the tentacles of a jellyfish. It should be noted that the hemispherical lampshade and light strip are only decorative and do not involve the movement principle of this utility model, therefore they are not shown in the accompanying drawings.

[0025] The working principle and operation process of this utility model:

[0026] By activating the drive mechanism 3, the drive mechanism 3 will drive the drive shaft 301 to rotate, and the first gear 4 on the drive shaft 301 will rotate along with it. Several transmission gear sets 5 that mesh with the first gear 4 will also rotate, that is, the transmission shaft 501 of the transmission gear set 5 will also rotate, which will drive the turntable 6 to rotate together, and the light strip on the turntable 6 will swing, thus creating the visual effect of jellyfish tentacles swinging.

[0027] Example 2

[0028] like Figure 1-6 As shown, this embodiment is based on Embodiment 1. This embodiment defines the specific structure of the umbrella-shaped mounting base 2 and the transmission gear set 5. Specifically, the umbrella-shaped mounting base 2 includes an upper mounting plate 201, a lower mounting plate 202, and several connecting rods 203. The two ends of the connecting rods 203 are respectively disposed on the lower surface of the upper mounting plate 201 and the upper surface of the lower mounting plate 202. The umbrella-shaped mounting base 2, composed of the upper mounting plate 201 and the lower mounting plate 202, can reduce the overall weight of the umbrella-shaped mounting base 2. At the same time, the presence of several through holes in the upper mounting plate 201 and the lower mounting plate 202 can further reduce the overall weight. The connecting rods 203 are vertically disposed on the lower mounting plate 202 to support the upper mounting plate 201.

[0029] Furthermore, both the upper mounting plate 201 and the lower mounting plate 202 are circular and concentrically arranged. Setting the upper mounting plate 201 and the lower mounting plate 202 as the center of the circle facilitates the semi-circular lampshade to cover the upper mounting plate 201. The concentric arrangement ensures that the side structures of the upper mounting plate 201 and the lower mounting plate 202 will not be exposed after the lampshade is installed, thus affecting the aesthetics.

[0030] Furthermore, the drive shaft 301 is located at the center of the upper mounting plate 201, which facilitates engagement with several transmission gear sets 5.

[0031] It should be noted that the transmission gear set 5 includes four transmission gear components arranged in an arc shape. This arc arrangement reduces the diameter of the two upper mounting plates 201 and the lower mounting plate 202. Adjacent transmission gear components mesh with each other for transmission. One of the transmission gear components located at the end of the arc meshes with the first gear 4. The gears are transmitted step by step through the arc arrangement. Each transmission gear component also includes an upper bearing seat 502, a lower bearing seat 503, and a second gear 504. The upper bearing seat 502 is disposed on the lower surface of the upper mounting plate 201, and the lower bearing seat 503 is disposed on the upper surface of the lower mounting plate 202. The two ends of the transmission shaft 501 are respectively disposed in the upper bearing seat 502 and the lower bearing seat 503. The second gear 504 is sleeved on the transmission shaft 501. The rotation of the second gear 504 drives the transmission shaft 501 to rotate, thereby driving the turntable 6 to rotate.

[0032] Example 3

[0033] like Figure 1-6 As shown, this embodiment is based on Embodiment 1. This embodiment defines the specific structure of the drive mechanism 3. Specifically, the drive mechanism 3 also includes a mounting bracket, a drive motor 302, a worm gear 303, a worm 304, and a housing 305. The drive motor 302 and the housing 305 are mounted on the mounting bracket, which provides mounting space for the drive motor 302 and the housing 305. The worm gear 303 and the worm 304 are disposed within the housing 305, and the housing 305 protects the worm gear 303 and the worm 304 to isolate them. Externally, the end of the worm 304 extends out of the side wall of the housing 305 and is connected to the output end of the drive motor 302 via a chain and sprocket assembly 7. The rotation of the output end of the drive motor 302 drives the end of the worm 304 to rotate via the chain and sprocket assembly 7. The worm 304 meshes with the worm wheel 303, thereby driving the worm wheel 303 to rotate. The top of the drive shaft 301 extends into the housing 305, and the worm wheel 303 is sleeved on the top of the drive shaft 301, thereby driving the drive shaft 301 to rotate, which in turn drives the first gear 4 to rotate.

[0034] Example 4

[0035] like Figure 1-6 As shown, this embodiment is developed based on embodiment one in order to solve the installation stability of column 1. Specifically, the bottom of column 1 is set on the upper surface of base frame 8, and the base frame 8 increases the contact area between column 1 and the ground. Four diagonal braces 9 are also evenly arranged on the circumference of the end of column 1 near the base frame 8 and fixedly connected to the base frame 8. The diagonal braces 9 enable column 1 to be stably erected on base frame 8.

[0036] 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.
