[0031] This utility model provides a modular globe, including a support base, a mounting base fixedly installed on the support base, a globe body, a first limiting rod, and a second limiting rod. The mounting base is an arc-shaped semi-enclosed shape adapted to the globe body. The globe body is installed inside the mounting base. Both the first limiting rod and the second limiting rod are semi-circular in shape. The two ends of the first limiting rod are fixedly installed on one side of the mounting base, and the two ends of the second limiting rod are detachably installed on the other side of the mounting base through a first connecting component and a second connecting component, respectively. The first limiting rod and the second limiting rod are in the same plane, forming a complete circle, which is used to limit the movement trajectory of the globe body.

[0032] Example 1

[0033] like Figures 1-9 As shown, this embodiment discloses a combined globe, including a support base 1, a mounting base 2 fixedly mounted on the support base 1, a globe body 4, a first limiting rod 3, and a second limiting rod 5. The mounting base 2 is an arc-shaped semi-enclosed shape (semi-circular shape) adapted to the globe body 4, and the globe body 4 is installed inside the mounting base 2. The first limiting rod 3 and the second limiting rod 5 are both semi-circular rod structures. The two ends of the first limiting rod 3 are fixedly mounted on one side of the mounting base 2, and the two ends of the second limiting rod 5 are detachably mounted on the other side of the mounting base 2 through the first connecting assembly and the second connecting assembly, respectively. The first limiting rod 3 and the second limiting rod 5 are in the same plane (different from the plane of the mounting base 2), thus forming a complete circle (adapted to the size of the globe body 4) to limit the movement trajectory of the globe body 4.

[0034] like Figure 4 As shown, the first connecting assembly includes a screw block 7, a first connecting block 6 fixed to the upper end of the second limiting rod 5, and a first sliding groove on the upper end of the side of the mounting base 2 connected to the second limiting rod. Both ends of the arc segment of the second limiting rod 5 are provided with a protrusion perpendicular to the arc tangent, and the first connecting block 6 is provided on the side of the protrusion away from the arc segment.

[0035] The first connecting block 6 is inserted into the first slide groove to connect the second limiting rod 5 with the mounting base 2. The top of the mounting base 2 is also provided with a threaded hole, which connects the outside and the first slide groove. The screw block 7 is provided with a threaded part that matches the threaded hole. The threaded part of the screw block 7 is inserted into the first slide groove from the outside along the threaded hole and presses the first connecting block 6.

[0036] Specifically, the first connecting block 6 is also provided with a first slot. When the first connecting block 6 is inserted into the first slide groove, the first slot is aligned with the screw block 7. The screw block 7 moves downward and inserts into the first slot, thereby firmly fixing the first connecting block 6 in the first slide groove.

[0037] like Figure 4 , 8 As shown, the second connecting assembly includes a mounting bracket 8 fixedly installed at the bottom of the mounting base 2, a second connecting block 61 fixedly installed at the lower end of the second limiting rod 5, a positioning rod 9, and a return spring 10.

[0038] Specifically, a second sliding groove is provided at the lower end of the side of the mounting base 2 that is connected to the second limiting rod, and the second connecting block 61 is inserted into the second sliding groove to realize the connection between the second limiting rod 5 and the mounting base 2.

[0039] Specifically, the mounting bracket 8 is L-shaped, and the bottom of the mounting bracket 8 and the mounting base 2 have through holes at corresponding positions. The positioning rod 9 is provided with a limiting ring, the diameter of which is larger than the diameter of the through hole. The part of the positioning rod 9 above the limiting ring is inserted upward into the through hole at the bottom of the mounting base 2 and extends into the second sliding groove. The part below the limiting ring passes downward through the through hole on the mounting bracket 8. The return spring 10 is sleeved on the positioning rod 9 and is located between the mounting bracket 8 and the limiting ring.

[0040] Optionally, the upper end of the positioning plate is triangular with a pointed top, and the bottom of the second connecting block 61 is provided with a second slot. When the second connecting block 61 is inserted into the second slide groove, the second slot is aligned with the positioning rod 9, and the top of the positioning rod 9 is inserted into the second slot under the elastic force of the return spring 10, thereby firmly fixing the second connecting block 61 in the first slide groove. The sliding connection between the positioning rod 9 and the second slot, as well as the elastic force of the return spring 10, jointly enhance the stability between the second limiting rod 5 and the mounting base 2, preventing loosening or displacement caused by external forces during use.

[0041] When it is necessary to remove the globe body 4 from the mounting base 2, simply turn the screw block 7 upward to disengage it from the first slide groove. Then, the first connecting block 6 can be pulled out from the first slide groove, thereby disconnecting the connection between the second limiting rod 5 and the upper part of the mounting base 2. Next, pull the positioning rod 9 downward to compress the return spring 10. The top of the positioning rod 9 slides out from the second slide groove. Then, the second connecting block 61 can be pulled out from the second slide groove, thereby disconnecting the connection between the second limiting rod 5 and the lower part of the mounting base 2. At this point, the globe body 4 can be removed from the mounting base 2.

[0042] When it is necessary to install the globe body 4 into the mounting base 2, first, install the globe body 4 into the mounting base 2, then insert the first connecting block 6 into the first sliding groove, then twist the screw block 7 downwards to insert it into the first slot, then pull the positioning rod 9 downwards to disengage its top from the second sliding groove, then insert the second connecting block 61 into the second sliding groove, release the positioning rod 9, and the top of the positioning rod 9 is inserted into the second slot under the action of the return spring 10, thus completing the installation of the globe body 4.

[0043] like Figure 1 , 7 As shown, in this embodiment, the combined globe also includes a lead screw 25 and a support 24. The support 24 is fixedly installed on the outside of the mounting base 2 (the side away from the globe body 4) and located in the middle of the mounting base 2. Threaded holes are provided at corresponding positions on the support 24 and the mounting base 2. After the lead screw 25 passes through the threaded holes on the support 24 and the mounting base 2, its head contacts the globe body 4, and the head of the lead screw is also provided with an anti-slip pad 26.

[0044] When using the modular globe, in order to ensure that the globe body 4 does not rotate spontaneously within the mounting base 2, the rotatable lead screw 25 makes the anti-slip pad 26 tightly contact the globe body 4, thereby fixing the globe body 4 and ensuring that it does not rotate.

[0045] like Figure 1 , 2 As shown, in this embodiment, a connecting box 11 is also included. The connecting box 11 has a cuboid structure and is fixedly installed at the bottom of the support base 1. The bottom of the connecting box 11 is open, and multiple support legs 13 that can extend out along the opening are provided inside the connecting box 11.

[0046] like Figure 5 , 6 As shown, the modular globe also includes a rotating rod 12, a connecting block 27, and a screw rod 14. The rotating rod 12 is arranged along the width direction of the connecting box 11, and its two sides are rotatably fixed to the side walls of the connecting box 11. The connecting block 27 is fixedly sleeved on the rotating rod 12, and the support leg 13 is fixedly installed on the connecting block 27. The screw rod 14 is located directly above the connecting block 27, passes through the top of the connecting box 11, and is threadedly connected to the connecting box 11. The bottom of the screw rod 14 also has a pressure block 15 and an anti-slip pad 26 provided on the pressure block 15.

[0047] When the support leg 13 extends out of the connecting box 11, the screw rod 14 is rotated so that the bottom of the screw rod 14 (anti-slip pad 26) contacts and presses against the connecting block 27 to prevent the rotating rod 12 from rotating, thereby ensuring the stability of the support leg 13.

[0048] like Figure 6 As shown, there are two sets of rotating rods 12, which are arranged on both sides of the length direction of the connecting box 11. Each set of rotating rods 12 is provided with two connecting blocks 27, and each connecting block 27 is equipped with a support leg 13. Therefore, in this embodiment, there are a total of four support legs 13.

[0049] like Figure 2 , 3As shown in Figure 9, the modular globe also includes a limiting assembly. The limiting assembly includes a bidirectional screw 17, a handle 23, a support box 16, a slider 18, and a limiting plate 19. The support box 16 is fixedly installed on the outer surface of the connecting box 11 and is arranged along the length of the connecting box 11. The bidirectional screw 17 is arranged along the length of the connecting box 11, and its two ends are rotatably installed on the side walls on both sides of the support box 16. One end of the bidirectional screw 17 extends out of the support box 16 and is fixedly connected to the handle 23. There are two sliders 18 and two limiting plates 19. The two ends of the side wall of the connecting box 11 along its length are provided with two rectangular sliding openings (the limiting plates 19 can move linearly in the sliding openings). The two sliders 18 are threadedly connected to the bidirectional screw 17. The two limiting plates 19 are fixedly connected to the two sliders 18 respectively, and the two limiting plates 19 are located in the two sliding openings respectively. When the bidirectional screw rotates, it drives the slider 18 to rotate, thereby driving the limiting plate 19 to move along the sliding opening to the edge of the connecting box 11. The rotating rod 12 on the corresponding side rotates, and the support leg 13 extends out from the opening at the bottom of the connecting box 11.

[0050] like Figure 3 , 6 As shown, specifically, when the bidirectional screw 17 rotates and drives the two sliders 18 to move to the left, both limiting plates 19 move to the left along the sliding opening. The left limiting plate 19 moves to the edge of the connecting box 11, thereby losing its supporting and limiting function for the left connecting block 27 and the supporting leg 13. The two supporting legs 13 on the left fall under the action of gravity, so as to drive the rotating rod 12 and the connecting block 27 to rotate. Then, the two supporting legs 13 on the left extend downwards out of the opening at the bottom of the connecting box 11.

[0051] Then, the bidirectional screw 17 rotates and drives the two sliders 18 to move to the right. Both limiting plates 19 move to the right along the sliding opening. The right limiting plate 19 moves to the right edge of the connecting box 11, thereby losing its supporting and limiting function on the right connecting block 27 and the supporting leg 13. The two supporting legs 13 on the right fall under the action of gravity, so as to drive the rotating rod 12 and the connecting block 27 to rotate. Then, the two supporting legs 13 on the right extend downwards out of the opening at the bottom of the connecting box 11.

[0052] like Figure 3 , 6 As shown, in this embodiment, the four support legs 13 located on the two rotating rods 12 are staggered in position so that all four support legs 13 can be retracted to a position parallel to the top of the connecting box 11.

[0053] Specifically, there are two sets of limiting components, which are set on both sides of the width direction of the connecting box 11. Each set of limiting components has a sprocket 20 on its bidirectional screw 17. The two sprockets 20 are connected by a chain 21 to ensure the synchronicity of the rotation of the two bidirectional screws 17. This facilitates the simultaneous driving of the two bidirectional screws 17, thereby making it easier to drive the limiting plate 19 to limit the connecting block 27.

[0054] like Figure 9 As shown, a protective box 22 is also provided on one side of the support box 16. The sprocket 20 and chain 21 are both housed inside the protective box 22, effectively preventing dust or debris from entering the transmission components and avoiding malfunctions or safety hazards caused by damage to the transmission components. At the same time, the protective box 22 also prevents users from accidentally touching the transmission components, improving the safety of use. The handle 23 is installed on the outside of the protective box 22.

[0055] like Figure 6 As shown, the connecting box 11 has two sliding openings on each side wall along its width direction, that is, the connecting box 11 has a total of four sliding openings on each side wall along its width direction. The limiting plate 19 is arranged along the width direction of the connecting box 11, and its two ends respectively overlap the corresponding sliding openings on the side walls of the connecting box 11 along its width direction. The limiting plate 19 is in contact with the bottom of the connecting block 27.

[0056] like Figure 1 As shown, in this embodiment, the length of the support leg 13 is adjustable.

[0057] In this embodiment, when using the modular globe, it is first placed on a podium or other table surface. The globe body 4 can then be slid freely, allowing it to rotate within the mounting base 2. When adjusting the height of the globe body 4 according to the usage scenario, first rotate the screw rod 14 to move the pressure block 15 away from the connecting block 27. Then, rotate the handwheel to rotate the bidirectional screw 17, causing the limiting plate 19 to be positioned at the edge of the connecting box 11, allowing the support leg 13 to slide out of the connecting box 11. Adjusting the length of the support leg 13 adjusts the height of the globe body 4. Then, rotate the screw rod 14 in the opposite direction to press the pressure block 15 onto the connecting block 27, thus fixing the connecting block 27 and preventing rotation of the connecting block 27 and the rotating rod 12, thereby ensuring the stability of the support leg 13. After the globe body 4 is adjusted to a suitable position, rotate the lead screw 25 to make its head and the anti-slip pad 26 make tight contact with the globe body 4, thus fixing the globe body 4 and ensuring it does not rotate.

[0058] In this embodiment, the second limiting component of the combined globe is detachably connected to the mounting base 2 via the first and second connecting components, facilitating the removal of the globe body 4 from the mounting base 2 and thus aiding in cleaning the globe body 4. The support legs 13 inside the connecting box 11 can also be extended and their height adjusted, making it easier for students at the back to observe the globe body 4. Users can choose a suitable observation angle according to their personal habits or teaching needs, improving ease of use and comfort.

[0059] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
