Embodiment

[0029] A modular foldable Christmas tree includes a first keel rod 1, a second keel rod 2 is arranged at the top of the first keel rod 1, a third keel rod 3 is arranged at the top of the second keel rod 2, the bottoms of the inner sides of the first keel rod 1, the second keel rod 2 and the third keel rod 3 are all fixedly connected with equally spaced first fixing frames 4, the tops of the inner sides of the first keel rod 1, the second keel rod 2 and the third keel rod 3 are all fixedly connected with equally spaced second fixing frames 9, a first support rod 5 is movably installed inside the first fixing frame 4, a sliding opening 6 is formed at the top of the first support rod 5, clamping strips 7 are fixedly connected to both sides of the inner cavity of the sliding opening 6, a second support rod 8 is movably installed inside the second fixing frame 9, one end of the second support rod 8 extends into the sliding opening 6, protrusions 10 are welded on the surface of the second support rod 8, and the second support rod 8 and the protrusions 10 are both adapted to the two clamping strips 7.

[0030] The specific usage process is as follows: First, this technical solution provides multiple usage modes. It can be used with a single part alone or multiple parts can be combined and used together. Among them, the first keel rod 1, the second keel rod 2, and the third keel rod 3 are the same in shape and style, only the size ratio is different. In the following description, only the third keel rod 3 will be mainly used for illustration. Usage mode one: used alone. The user removes the second keel rod 2 and the first keel rod 1 from the third keel rod 3, or only takes the third keel rod 3 for use. In the storage state, the entire third keel rod 3 and all the structures on the third keel rod 3 are in a contracted state. When in use, first expand the second support rod 8 outward. At the same time, one end of the second support rod 8 rotates within the second fixing frame 9 on the third keel rod 3, and the other end of the second support rod 8 will move outward. At the same time, the end of the second support rod 8 connected to the first support rod 5 will also slide within the sliding opening 6 on the first support rod 5 until the end of the second support rod 8 can no longer move. Then expand the first support rod 5 outward. At the same time, one end of the first support rod 5 rotates within the first fixing frame 4. Finally, the first support rod 5 is restricted by the end of the second support rod 8 and cannot move. During this period, the expansion degrees of the second support rod 8 and the first support rod 5 need to be adjusted in sequence until both the first support rod 5 and the second support rod 8 can no longer be expanded. In this way, the first support rod 5 and the second support rod 8 can also support each other to prevent the second support rod 8 and the first support rod 5 from moving randomly. When the second support rod 8 slides within the sliding opening 6, the protrusion 10 on the second support rod 8 will also pass through the sliding opening 6 in sequence. At the same time, the protrusion 10 will also pass between the two clamping strips 7 on the inner side of the sliding opening 6. During this process, the protrusion 10 will first move out of the card slot formed between the current two clamping strips 7, then squeeze the two clamping strips 7 to cause deformation. After that, the protrusion 10 will follow the second support rod 8 through the current card slot and enter the next card slot formed by the two clamping strips 7, and the two clamping strips 7 will return to their original state, thereby positioning and fixing the protrusion 10 and the second support rod 8. This process is repeated until after the second support rod 8 and the first support rod 5 are fully expanded, the protrusion 10 at the corresponding position on the second support rod 8 will be stuck in the card slot at the corresponding position formed by the two clamping strips 7. Among them, after the protrusion 10 at the current position moves out of the card slot at the current position, it will also move out of the sliding opening 6, and then the next protrusion 10 will be stuck in the card slot at the next position. This is the position change of the protrusion 10 between the two threaded pin rods 17 during the expansion process of the second support rod 8 and the first support rod 5. Then, expand all the second support rods 8 and the first support rods 5 in sequence according to the above operations. Finally, cover the attached decorative cloth cover on multiple second support rods 8. In this way, the Christmas tree is formed. Finally, install the end head 14 on the top of the third keel rod 3 in a threaded connection manner. It should be noted that the installation method of the end head 14 with the first keel rod 1 and the second keel rod 2 is also the same, and the usage method of the first keel rod 1 and the second keel rod 2 is the same as that of the third keel rod 3, and it can be carried out according to the above operation process. And all the hooks 12 can also hang some other decorations to add beauty to the Christmas tree;

[0031] Using Mode 2 in combination, when the first keel rod 1, the second keel rod 2, and the third keel rod 3 are in a folded and contracted state, the third keel rod 3, the second keel rod 2, and the first keel rod 1 are arranged in an up-and-down position. Then, the third keel rod 3 is installed at the top of the second keel rod 2 in a threaded connection manner, and the first keel rod 1 is installed at the bottom of the second keel rod 2 in a threaded connection manner. Finally, the end head 14 is installed at the top end of the third keel rod 3. In this way, a large Christmas tree is assembled. After that, all the first struts 5 and the second struts 8 are unfolded according to the operation method of Mode 1. In this way, a multi-layer Christmas tree can be formed. Moreover, when carrying, the third keel rod 3, the second keel rod 2, and the first keel rod 1 can be carried into the room separately in sequence and then assembled for use. In this way, it will not be restricted by buildings such as door frames, stairs, and elevators, providing convenience for the user's carrying work. At the same time, it is also convenient to carry onto the transportation tool, providing convenience for the user's transportation work.

[0032] Therefore, a structural design that can be combined with each other and disassembled for individual use is adopted.

In this way, the first fixing bracket 4 can be installed on the top of the third keel rod 3 to enhance the aesthetics of the third keel rod 3. Among them, the second threaded pin rod 17 and the third threaded pin rod 19 can also be installed in the first threaded groove 15 in the same way. In this way, the end head 14 can also be installed on the second keel rod 2 and the first keel rod 1, thereby enhancing the aesthetics of the second keel rod 2 and the first keel rod 1 and providing convenience for the user's work and use.

[0041] A fourth threaded groove 20 adapted to the first threaded pin rod 13, the second threaded pin rod 17, and the third threaded pin rod 19 is opened at the bottom of the first keel rod 1.

[0042] Specifically, with the provision of the fourth threaded groove 20, the fourth threaded groove 20 can be used for other similar connections except for the first threaded pin rod 13, the second threaded pin rod 17, and the third threaded pin rod 19, thereby forming other combination schemes except the combination usage scheme shown in this solution. Here, the other combination schemes include the combination scheme in this solution but are not limited to adding other components on the basis of this solution to form other styles and sizes of schemes, thereby providing more choices and convenience for the user's use.

[0043] The third threaded pin rod 19, the second threaded pin rod 17, and the first threaded pin rod 13 are all adapted to the first threaded groove 15, the second threaded groove 16, the third threaded groove 18, and the fourth threaded groove 20.
