All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1:

[0031] Please refer to Figures 1-3 as shown, an adjustable globe, comprising:

[0032] A base 1, and a circular groove 2 is opened at the center position of the outer wall of the top of the base 1;

[0033] An adjusting mechanism 3, the adjusting mechanism 3 is installed inside the circular groove 2, the top end of the adjusting mechanism 3 is provided with a fixed seat 4, and an arc-shaped frame 5 is fixedly installed on the outer wall of the top of the fixed seat 4;

[0034] The rotating mechanism 6 is installed at one end of the outer wall of the top of the arc-shaped frame 5. A spherical shell 7 is installed at the output end of the rotating mechanism 6. A map is pasted on the surface of the spherical shell 7. The spherical shell 7 is located inside the arc-shaped frame 5. A light shielding plate 11 is installed at the middle position inside the spherical shell 7. Horizontal plates 12 are fixedly installed at positions near the upper and lower ends on one outer wall of the light shielding plate 11. A lighting lamp 13 is fixed on the opposite outer walls of the two horizontal plates 12 by bolts. One end of the spherical shell 7 away from the rotating mechanism 6 is fixed with a connecting mechanism, and one end of the connecting mechanism is installed at one end of the outer wall of the bottom of the arc-shaped frame 5.

[0035] As can be seen from the above, when in use, the height and facing angle of the globe are adjusted through the adjusting mechanism 3, and then the lighting lamp 13 inside the spherical shell 7 is turned on. The light is blocked by the light shielding plate 11, so that the globe shows an effect of being half bright and half dark. Then the rotating mechanism 6 is started to drive the globe to rotate slowly, simulating the rotation of the earth, which is convenient for better displaying the globe.

[0036] Specifically, the adjusting mechanism 3 includes a turntable 301. The turntable 301 is rotatably clamped on the inner wall of the circumference of the circular groove 2. An electric cylinder 302 is fixedly installed on the outer wall of the top of the turntable 301. The fixed seat 4 is installed at the top end of the extension rod of the electric cylinder 302.

[0037] As can be seen from the above, the electric cylinder 302 is started to adjust the overall height of the device.

[0038] Specifically, a handle 303 is fixedly installed on one side of the outer wall of the top of the turntable 301.

[0039] As can be seen from the above, the turntable 301 is driven to rotate by the handle 303, so as to change the facing angle of the device.

[0040] Specifically, the rotating mechanism 6 includes a micro motor 601. The micro motor 601 is installed on one side of the outer wall of the top of the arc-shaped frame 5. One end of the output shaft of the micro motor 601 is sleeved with a fixed cylinder 602. One end of the fixed cylinder 602 is installed at one end of the spherical shell 7.

[0041] As can be seen from the above, the micro motor 601 is started to drive the fixed cylinder 602 to rotate, thereby driving the rotation of the spherical shell 7. An installation hole is opened at a position of the spherical shell 7 near the fixed cylinder 602, which is convenient for the wire of the lighting lamp 13 to extend outwards.

[0042] Specifically, the connecting mechanism includes a plug rod 9. The plug rod 9 is rotatably inserted at one end of the outer wall of the bottom of the arc-shaped frame 5. The top end of the plug rod 9 is sleeved with a sleeve 8. The top end of the sleeve 8 is installed at one end of the spherical shell 7 facing the fixed cylinder 602.

[0043] As can be seen from the above, the other end of the spherical shell 7 is fixed by the sleeve 8 and the plug rod 9, ensuring the stable rotation of the spherical shell 7 when the rotating mechanism 6 drives the spherical shell 7 to rotate.

[0044] Specifically, a rubber pad 10 is adhered to the outer wall of the bottom of the base 1.

[0045] As can be seen from the above, the rubber pad 10 at the bottom of the base 1 increases the anti-slip effect of the device.

[0046] Working principle: During use, the height and facing angle of the globe are adjusted through the adjusting mechanism 3, and then the lighting lamp 13 inside the spherical shell 7 is turned on. The light is blocked by the light shielding plate 11, so that the globe presents an effect of being half bright and half dark. Then, the rotating mechanism 6 is started to drive the globe to rotate slowly, simulating the rotation of the earth, which is convenient for better displaying the globe.

[0047] Embodiment 2:

[0048] Reference Figure 4 As shown, this embodiment is basically the same as the previous embodiment. The difference is that a mounting seat 16 is fixedly installed on one outer wall of the base 1. A card slot is opened on one outer wall of the mounting seat 16. An enlarging assembly is arranged inside the card slot. The enlarging assembly includes a magnifying glass 15. The magnifying glass 15 is clamped on the inner wall of the card slot. One end of the magnifying glass 15 is fixedly installed with a telescopic spring 14. One end of the telescopic spring 14 is fixedly installed on one inner wall of the card slot.

[0049] As can be seen from the above, the magnifying glass 15 is clamped in the mounting seat 16 and fixed on one side of the card slot by using the telescopic spring 14. When taking out the magnifying glass 15, by stretching the telescopic spring 14, the magnifying glass 15 is placed above the map on the surface of the spherical shell 7, so as to facilitate magnifying the map and better observing the details of the map.
