Description

Technical Field

[0001] This utility model relates to the field of globe technology, specifically a device with polar day and polar night display functions. Background Technology

[0002] A globe is a model of the Earth. Globes were created to facilitate understanding of the Earth. People modeled the Earth's shape and scaled it down to a specific ratio. Current types of globes include: latitude and longitude grid globes, latitude and longitude globes, political division globes, topographic globes, schematic globes, educational globes, large display globes, craft and gift globes, antique-style globes, magnetic levitation globes, and luminous globes. Among these, those used for teaching are primarily: latitude and longitude grid globes, latitude and longitude globes, political division globes, topographic globes, and educational globes. Latitude and longitude grid globes, political division globes, topographic globes, and educational globes emphasize annotation, lookup, and memorization functions; while latitude and longitude globes focus on understanding geographical knowledge.

[0003] Existing globes have limited functionality to aid student comprehension. Most globes currently only label geographical information externally, limiting their comprehension capabilities. They cannot flexibly observe or view the globe from the inside or from both inside and outside, making many abstract concepts difficult to understand. They cannot directly display angular velocity, linear velocity, and the terminator of the four seasons, nor can they directly demonstrate the polar day and polar night phenomena within the polar circles. This makes it difficult to imagine and understand these concepts, hindering students' enthusiasm and interest in learning geography. Therefore, this paper proposes a device that can display polar day and polar night phenomena. Utility Model Content

[0004] In view of this, the present invention provides a device with polar day and polar night display function to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

The polar day and polar night display mechanism is installed outside the main body. The main body includes an arc-shaped plate. Two pin seats are symmetrically fixedly connected to the inner side wall of the arc-shaped plate. Bearing pins are inserted into the interior of each of the two pin seats. Eight meridian rods are symmetrically fixedly connected to the adjacent ends of the two bearing pins. A first latitude rod is fixedly connected to the outer side wall of the eight meridian rods. A second latitude rod is fixedly connected to the outer side wall of the eight meridian rods above and below the first latitude rod.

[0006] The polar day and polar night display mechanism includes an elastic polar day cover and a polar night cover. The elastic polar day cover is fitted over the eight warp rods, and the polar night cover is fitted over the elastic polar day cover. The elastic polar day cover has marking lines on its exterior.

[0007] More preferably, a base is provided below the arc-shaped plate, and a support rod is fixedly connected to the top of the base. The top of the support rod is fixedly connected to the outer wall of the arc-shaped plate.

[0027] like Figure 1-7As shown, this utility model embodiment provides a device with polar day and polar night display function, including a main body 1 and a polar day and polar night display mechanism 2. The polar day and polar night display mechanism 2 is installed outside the main body 1. The main body 1 includes an arc-shaped plate 13. Two pin seats 14 are symmetrically fixedly connected to the inner side wall of the arc-shaped plate 13. Bearing pins 15 are inserted into the interior of each of the two pin seats 14. Eight meridian rods 16 are symmetrically fixedly connected to the adjacent ends of the two bearing pins 15. First latitude rods 17 are fixedly connected to the outer side walls of the eight meridian rods 16. Second latitude rods 18 are fixedly connected to the outer side walls of the eight meridian rods 16 above and below the first latitude rods 17.

[0028] The polar day and polar night display mechanism 2 includes an elastic polar day cover 21 and a polar night cover 22. The elastic polar day cover 21 is fitted over the outside of eight warp rods 16, and the polar night cover 22 is fitted over the outside of the elastic polar day cover 21. The outside of the elastic polar day cover 21 is provided with marking lines 213.

[0029] In one embodiment, a base 11 is provided below the arc plate 13, and a support rod 12 is fixedly connected to the top of the base 11. The top of the support rod 12 is fixedly connected to the outer wall of the arc plate 13. The base 11 provides support for the device. The angle between the support rod 12 and the ground is 90 degrees. The support rod 12 is used as the earth axis, so that the equator is parallel to the ground, which is conducive to students' observation and understanding.

[0030] In one embodiment, the inner sidewall of the arc plate 13 is provided with a plurality of latitude grooves 131; the latitude grooves 131 facilitate the observation of latitude during demonstration.

[0031] In one embodiment, a longitude marker block 19 is fixedly connected to the outer wall of the meridian rod 16; by setting the longitude marker block 19, the longitude is filled in on the longitude marker block 19, which facilitates the observation of the longitude.

[0032] In one embodiment, the top of the elastic polar day cover 21 has a first through hole 211, the bottom of the elastic polar day cover 21 has a second through hole 212, and the outer side wall of the polar night cover 22 has two symmetrical grooves 221. The first through hole 211 facilitates the passage of the bearing pin 15.
