[0008] Furthermore, the lower insertion shaft includes a lower fixing seat that is fixedly mounted to the display sphere, a fixing shaft is mounted at the center of the lower fixing seat, and a bearing is installed between the fixing shaft and the lower fixing seat.

[0009] Furthermore, the top of the lower socket is provided with a fixing hole for connection with the bottom end of the fixing shaft.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model adopts a modular connection structure combining spring pins, lower sockets, upper sockets, and lower insert shafts, which allows the display sphere to be easily installed on the bracket and easily disassembled when needed. The entire assembly and disassembly process does not require any external tools (such as screwdrivers, wrenches, etc.) and can be completed with simple hand movements, which has a high degree of convenience. This ensures that users can replace the display sphere extremely efficiently. Whether it is to display diverse geographical and topographical information or to switch different decorative themes, users can quickly respond to changes in needs, fully meet personalized and diversified usage needs, and greatly improve the practicality and flexibility of the product.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 6 As shown: This utility model provides a globe that can be quickly disassembled and replaced, including a base 1, a bracket 2 fixedly installed on the top of the base 1, a display sphere 3 rotatably installed on the inner side of the bracket 2, and spring pins 4 and lower sockets 5 respectively provided at the upper and lower ends of the bracket 2; an upper socket 6 and a lower insertion shaft 7 are respectively installed at the upper and lower ends of the display sphere 3, the bottom end of the spring pin 4 is inserted into the upper socket 6, and the lower socket 5 is inserted into the top end of the lower insertion shaft 7.

[0023] The spring pin 4 includes a fixed cylinder 401 fixedly installed with the bracket 2, and a plug shaft 402 slidably installed inside the fixed cylinder 401. The top end of the plug shaft 402 extends out from the top end of the fixed cylinder 401 and is fixedly connected to a pull button 403, so that the plug shaft 402 can be separated from the upper socket 6 by pulling the pull button 403 during use. The bottom end of the plug shaft 402 extends out from the bottom end of the fixed cylinder 401 and is provided with a plug connector.

[0024] The plug shaft 402 has a step on its outer side, and a spring is fitted on the top side near the step. The two ends of the spring are respectively abutted against the step and the inner top side of the fixed cylinder 401, so that the bottom end of the plug shaft 402 can be stably pressed against the upper socket 6 during installation, ensuring high stability during use.

[0025] The upper socket 6 includes an upper fixing base 601 that is fixedly installed with the display sphere 3. An upper connector 602 is rotatably mounted at the center of the upper fixing base 601. A bearing is installed between the upper connector 602 and the upper fixing base 601 to reduce the friction between them, allowing the display sphere 3 to rotate easily. The top of the upper connector 602 is provided with a socket that matches and connects to the plug.

[0026] The lower insertion shaft 7 includes a lower fixing seat 701 that is fixedly installed with the display sphere 3. A fixing shaft 702 is installed at the center of the lower fixing seat 701. A bearing is installed between the fixing shaft 702 and the lower fixing seat 701 to reduce the friction between the fixing shaft 702 and the lower fixing seat 701, so that the display sphere 3 can rotate easily.

[0027] The lower socket 5 has a fixing hole at its top end that connects to the bottom end of the fixing shaft 702; the bottom end of the fixing shaft 702 is a prism with a tapered bottom end to facilitate a quick and stable connection with the fixing hole.

[0028] The working principle of this embodiment is as follows: During disassembly, the pull button 403 can be pulled to disengage the bottom connector of the plug shaft 402 from the socket of the upper connector 602. At this time, the display sphere 3 can be pushed upward to disengage the lower plug shaft 7 at its bottom from the lower socket 5. Then, the display sphere 3 can be removed. When a new display sphere 3 needs to be installed, the pull button 403 can be pulled to retract the bottom connector. Then, the lower plug shaft 7 at the bottom of the display sphere 3 can be aligned with the lower socket 5 and inserted. After insertion, the pull button 403 can be released. Under the action of the spring, the plug shaft 402 can be popped out, allowing its bottom connector to connect with the upper socket 6. This completes the quick installation.

[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
