[0001] This utility model relates to the field of Christmas tree technology, and in particular to a simulated Christmas tree. Background Technology

[0002] Christmas trees are a type of decorative material, primarily serving a decorative function. They have a long history of use in the decoration field and are widely used in homes or specific public settings, such as shopping mall showrooms.

[0003] In existing technologies, Christmas trees are relatively large, and their use is generally limited to specific holidays or locations. Therefore, they need to be moved and stored after their use. To ensure stability during placement and prevent children from pushing them, the base of the Christmas tree is typically flat to avoid any danger. However, this design requires a small trolley for easy movement, which is somewhat inconvenient. Therefore, we propose a simulated Christmas tree. Summary of the Invention

[0004] The purpose of this invention is to provide a simulated Christmas tree to solve the problem that the bottom of the Christmas tree is made flat for stability, which requires the use of a trolley when moving it.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simulated Christmas tree, comprising a resin simulated wooden stake, a cavity formed on the lower surface of the resin simulated wooden stake, a bidirectional screw rotatably connected to the inner wall of the cavity, connecting sleeves threaded onto the two opposite threads of the bidirectional screw, a limiting groove formed on the top wall of the cavity, a sliding block fixedly connected to the upper surface of the connecting sleeve, the sliding block extending into the interior of the limiting groove, the sliding block slidably connected to the limiting groove, a displacement disk provided inside the cavity, a connecting rod rotatably connected to the lower surface of the connecting sleeve, the lower end of the connecting rod rotatably connected to the upper surface of the displacement disk, a rotating disk fixedly connected to the lower surface of the displacement disk, a moving wheel provided on the lower surface of the rotating disk, and a limiting component provided on the rotating disk.

[0008] Preferably, an annular rubber pad is fixedly connected to the outer surface of the ball bearing and the limiting rod, and to the lower surface of the resin simulated wood pile, and the right end of the bidirectional screw rotates through the right side surface of the resin simulated wood pile.

[0010] Preferably, the resin simulated wooden stake has a conical shell on its upper side, and a snap-fit ​​protrusion is fixedly connected to the lower surface of the conical shell.

[0011] Preferably, the snap-fit ​​protrusion is adapted to the snap-fit ​​groove, and a hook is fixedly connected to the outer surface of the conical shell.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please refer to Figures 1-5. This utility model provides a technical solution: a simulated Christmas tree, including a resin simulated wooden stake 1. A cavity 2 is formed on the lower surface of the resin simulated wooden stake 1. A bidirectional screw 3 is rotatably connected to the inner wall of the cavity 2. Connecting sleeves 4 are threaded onto the two opposite threads of the bidirectional screw 3. A limiting groove 5 is formed on the top wall of the cavity 2. A sliding block 6 is fixedly connected to the upper surface of the connecting sleeve 4. The sliding block 6 extends into the interior of the limiting groove 5 and is slidably connected to the limiting groove 5. A displacement disk 7 is provided inside the cavity 2. A connecting rod 8 is rotatably connected to the lower surface of the connecting sleeve 4. The lower end of the connecting rod 8 is rotatably connected to the upper surface of the displacement disk 7. A rotating disk 9 is fixedly connected to the lower surface of the displacement disk 7. A moving wheel 10 is provided on the lower surface of the rotating disk 9. A limiting component is provided on the rotating disk 9. With the help of the bidirectional screw 3 and the connecting rod 8, the displacement disk 7 and the moving wheel 10 can be driven. Thus, when needed, the moving wheel 10 can be controlled to extend, solving the problem of the Christmas tree being inconvenient to move.

[0025] Furthermore, the limiting assembly includes a limiting rod 11, which is fixedly connected to the upper surface of the rotating disk 9. A limiting cavity 12 is formed in the top wall of the cavity 2. The upper end of the limiting rod 11 slides through the interior of the limiting cavity 12. A limiting disk 13 is fixedly connected to the upper end of the limiting rod 11. A ball bearing 14 is movably connected to the inner wall of the limiting cavity 12. The ball bearing 14 is connected to the outer surface of the limiting rod 11. An annular rubber pad 15 is fixedly connected to the lower surface of the resin simulated wood pile 1. The right end of the bidirectional screw 3 rotates through the right side surface of the resin simulated wood pile 1. A control knob 16 is fixedly connected to the right end of the bidirectional screw 3. A snap-fit ​​is formed on the upper surface of the resin simulated wood pile 1. The upper side of the resin simulated wooden stake 1 is provided with a conical shell 18. The lower surface of the conical shell 18 is fixedly connected with a snap-fit ​​protrusion 19, which is adapted to the snap-fit ​​groove 17. The outer surface of the conical shell 18 is fixedly connected with a hook 20. The upper surface of the conical shell 18 is also provided with a snap-fit ​​groove 17. There are multiple sets of conical shells 18. The uppermost conical shell 18 has a cross groove 21 on its upper surface. When placing lamps and decorations, the hook 20 can be used to complete the task more conveniently. At the same time, the detachable conical shell 18 can reduce the vertical space occupied during storage and avoid the problem of inconvenience in storage due to its height.

[0026] Working principle: When the Christmas tree needs to be moved, the control knob 16 can be rotated, which in turn drives the bidirectional screw 3 to rotate. When the bidirectional screw 3 rotates, the movement trajectory of the connecting sleeve 4 is restricted by the sliding block 6 and the limiting groove 5. Therefore, when the bidirectional screw 3 rotates, it synchronously drives the two connecting sleeves 4 to move in opposite directions. Since the length of the connecting rod 8 is fixed and the distance between the lower connection points of the two connecting rods 8 is fixed, when the distance between the upper connection points of the two connecting rods 8 changes, it synchronously pulls the displacement disk 7 vertically. The displacement disk 7 moves as it moves... The limit rod 11 and the limit plate 13 move synchronously. When the limit rod 11 moves, the ball bearing 14 reduces the friction during its movement. During the movement of the displacement plate 7, the rotating plate 9 drives the moving wheel 10 to move synchronously. When the moving wheel 10 moves to the outside of the cavity 2 and contacts the ground, it lifts the Christmas tree, causing the annular rubber pad 15 to detach from the ground. At this time, the Christmas tree can be moved freely by pushing it. When the Christmas tree is placed, the annular rubber pad 15 improves its stability, and the hook 20 is used to place decorative lights and items. At the same time, multiple conical shells 18 can be disassembled when storing, thus avoiding the problem of difficulty in storage due to their height.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
