Description

Technical Field

[0001] This utility model relates to the technical field of globes, and in particular to a rolling globe. Background Technology

[0002] A globe is a model of the Earth made by people to facilitate understanding of the Earth. It is modeled after the shape of the Earth and reduced to a certain scale. It can be used to demonstrate the movement of the Earth, the alternation of day and night, the changes of seasons, and to understand the distribution and relative positions of the world's land and sea.

[0003] A globe mainly consists of a stand and a sphere. A sticker with a printed map is affixed to the surface of the sphere, and rotating the sphere allows viewing different locations on the globe. With changing market demands, globes with a sphere that can rotate freely relative to the stand have emerged. For example, Chinese patent document CN214377339U discloses a globe that can rotate in all directions. It discloses that the sphere can detach from the base for easy observation, and that a counterweight is installed inside the sphere to maintain a certain posture between the sphere and the base.

[0004] However, existing omnidirectional rotatable globes, while allowing the sphere to rotate freely relative to the base, also suffer from reduced stability. Improving the stability of the sphere relative to the base requires a larger base to ensure sufficient distance between the omnidirectional rotation mechanisms supporting the sphere, but increasing the base volume increases production costs. Therefore, existing omnidirectional rotatable globes present a practical contradiction between the size of the base and the stability of the sphere. To resolve this contradiction, the rolling globe of this application is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a rolling globe that can reduce the size of the base while improving the stability of the sphere.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A rolling globe, comprising:

[0008] A base, wherein an arc-shaped groove is formed on the base, a magnetic block is provided at the lowest point of the inner sidewall of the arc-shaped groove, and at least one support part is also provided on the inner sidewall of the arc-shaped groove; and

[0009] A sphere is detachably placed on the support. A magnet is provided on the inner sidewall of the sphere. When the support abuts against the sphere, the magnet attracts the magnetic block. There is a gap between the outer sidewall of the sphere and the magnetic block.

[0010] Optionally, the distance between the outer wall of the sphere and the magnetic block is 2mm to 3mm.

[0011] Optionally, the support portion is a convex ring, which is disposed at the highest point of the arc-shaped groove.

[0012] Optionally, the convex ring is provided with an arc surface, which abuts against the outer wall of the sphere.

[0013] Optionally, the support is a ball-bearing caster.

[0014] Optionally, three support parts are provided, the three support parts are set at the same height, and the three support parts are distributed at equal intervals between each other.

[0015] Optionally, a light-emitting part is also provided on the inner sidewall of the sphere.

[0016] Optionally, the light-emitting part includes a light-emitting base, a circuit board, a battery, and a plurality of lamp beads. The light-emitting base is disposed on the inner sidewall of the sphere. The circuit board and the battery are both disposed inside the light-emitting base, and the circuit board is electrically connected to the battery. Each of the lamp beads is disposed on the circuit board, and each of the lamp beads is oriented towards the magnet.

[0017] Optionally, the sphere comprises two hemispheres that are interlocked, the magnet is located on one of the two hemispheres, and the light-emitting base is disposed on the other of the two hemispheres.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] This invention relates to a rolling globe, comprising a base and a sphere. The base has an arc-shaped groove, and a magnetic block is located at the lowest point of the inner wall of the groove. At least one support portion is also provided on the inner wall of the groove. The sphere can be detachably placed on the support portion. A magnet is located on the inner wall of the sphere.

[0027] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0028] like Figures 1 to 3 As shown, a rolling globe 10 includes a base 100 and a sphere 200. The base 100 has an arc-shaped groove 110. A magnetic block 300 is provided at the lowest point of the inner sidewall of the arc-shaped groove 110. At least one support part 400 is also provided on the inner sidewall of the arc-shaped groove 110. The sphere 200 can be detachably placed on the support part 400. A magnet 500 is provided on the inner sidewall of the sphere 200. When the support part 400 abuts against the sphere 200, the magnet 500 magnetically attracts the magnetic block 300, and there is a gap between the outer sidewall of the sphere 200 and the magnetic block 300.

[0029] It should be noted that, for example, the magnetic block 300 is made of iron, cobalt, nickel, or their alloys. The concave shape of the arc-shaped groove 110 is adapted to the shape of the sphere 200, ensuring that the sphere 200 can be located within the arc-shaped groove 110. The support part 400 supports the sphere 200 to reduce the contact area between the sphere 200 and the base 100, thereby reducing the rolling friction of the sphere 200. The cooperation between the magnetic block 300 and the magnet 500 ensures the stability of the sphere 200 when placed. In particular, by increasing the magnetic attraction, the sphere 200 needs to overcome the magnetic attraction to detach from the support part 400 when subjected to a lateral push. The sphere 200 can be detachably placed on the support part 400, allowing the user to remove the sphere 200 separately from the base 100, increasing the flexibility of use. The space between the outer wall of the sphere 200 and the magnetic block 300 ensures a clean appearance for the sphere 200 and prevents the magnetic block 300 from directly contacting and scratching the map on the outer surface of the sphere 200. Operation is simple; users can easily remove and place the sphere 200, increasing ease of use. The arc-shaped groove 110 design ensures the smoothness and stability of the sphere 200 during rolling, enhancing the user experience. In particular, the magnetic attraction significantly reduces the volume of the base 100, thereby reducing the area of ​​the support 400 acting on the sphere 200, while ensuring sufficient stability between the sphere 200 and the base 100.

[0030] In one embodiment, the distance between the outer wall of the sphere 200 and the magnetic block 300 is 2mm to 3mm.

[0031] It should be noted that, for example, the distance between the outer wall of the globe 200 and the magnetic block 300 can also be 2.5mm. This ensures the stability of the globe 200 when placed and the magnetic attraction effect, while avoiding direct contact between the magnetic block 300 and the outer wall of the globe 200, maintaining the cleanliness and aesthetics of the globe 200. The magnetic force within this distance range is sufficient to maintain the stability of the globe 200, preventing it from sliding or rolling under slight external forces, ensuring the safety and reliability of the globe. Furthermore, a distance of 2mm to 3mm makes it easier for users to remove and place the globe 200, improving ease of use. At the same time, when the globe is not used for extended periods, it effectively reduces the amount of dust and impurities entering the space between the globe 200 and the magnetic block 300, keeping the globe clean, extending its lifespan, and enhancing the user experience.

[0032] like Figure 2 In one embodiment, the support portion 400 is a convex ring, which is disposed at the highest point of the arc-shaped groove 110.

[0033] It should be noted that the convex ring is located at the highest point of the arc-shaped groove 110. The design of the convex ring provides a stable support point, ensuring the balance and stability of the sphere 200 when placed. At the same time, it allows the sphere 200 to be naturally centered when placed, avoiding instability caused by improper positioning. In one embodiment, the convex ring and the base 100 are integrally formed.

[0034] like Figure 2 As shown, in one embodiment, the convex ring is provided with an arc surface 410, which abuts against the outer wall of the sphere 200.

[0035] It should be noted that the arc surface 410 contacts the sphere 200, ensuring the smoothness and stability of the sphere 200 during placement. The design of the arc surface 410 reduces the contact area between the sphere 200 and the support part 400, reducing friction and making the sphere 200 smoother during placement and rolling, avoiding wear and damage caused by sharp edges. At the same time, the arc surface 410 fits tightly against the outer wall of the sphere 200, providing uniform support force, ensuring the balance and stability of the sphere 200, preventing the sphere 200 from tilting or sliding under slight external forces, and improving the safety and reliability of the globe.

[0036] like Figure 3 As shown, in one embodiment, the support portion 400 is a ball-bearing caster wheel.

[0037] It should be noted that this design further improves the smoothness and stability of the ball 200 during placement and rolling. The ball caster design further reduces the friction between the ball 200 and the support 400, making the ball 200 smoother during placement and rolling, and avoiding wear and damage caused by friction. At the same time, the ball caster provides multi-directional freedom, ensuring flexible rotation of the ball 200 in all directions, enhancing the user's operating experience.

[0038] In one embodiment, three support parts 400 are provided, the three support parts 400 are set at the same height, and the three support parts 400 are distributed at equal intervals between each other.

[0039] It should be noted that the support portion 400 is configured as three structures of equal height and equidistant distribution, ensuring the balance and stability of the sphere 200 during placement. The equidistantly distributed support portions 400 provide uniform support force, enabling the sphere 200 to receive stable support in all directions, thereby enhancing the balance and anti-tipping ability of the sphere 200.

[0040] like Figure 2 As shown, in one embodiment, a light-emitting part 600 is also provided on the inner sidewall of the sphere 200.

[0041] It should be noted that the light-emitting part 600 is luminous, causing the sphere 200 to glow, thus enhancing the visual appeal and functionality of the globe. The light-emitting part 600 can be used to highlight specific geographical information or markers, enhancing the educational and display effects.

[0042] like Figure 2 As shown, in one embodiment, the light-emitting part 600 includes a light-emitting base 610, a circuit board 620, a battery 630, and a plurality of lamp beads 640. The light-emitting base 610 is disposed on the inner side wall of the sphere 200. The circuit board 620 and the battery 630 are both disposed inside the light-emitting base 610, and the circuit board 620 and the battery 630 are electrically connected. Each lamp bead 640 is disposed on the circuit board 620, and each lamp bead 640 is disposed facing the magnet 500.

[0043] It should be noted that the light-emitting base 610 can be mounted on the inner wall of the sphere 200 by screws or by adhesive. The circuit board 620 and battery 630 are both mounted inside the light-emitting base 610. Each LED 640 is positioned facing the magnet 500, allowing light to fill the interior of the sphere 200 and providing uniform illumination.

[0044] like Figures 1 to 3 As shown, in one embodiment, the sphere 200 includes two hemispheres 210 that are interlocked, a magnet 500 is located on one of the two hemispheres 210, and a light-emitting base 610 is disposed on the other of the two hemispheres 210.

[0045] It should be noted that dividing the sphere 200 into two hemispheres 210 makes assembly and maintenance more convenient. The interlocking design of the two hemispheres 210 ensures the structural stability and sealing of the sphere 200, preventing internal components from being affected by the external environment.

[0046] In one embodiment, the base 100 is made of metal or wood. Further, the base 100 may also be made of plastic.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
