Description

Technical Field

[0001] This utility model relates to the field of decorative crafts, specifically a modular Christmas tree quick assembly structure. Background Technology

[0002] In the realm of holiday decorations, Christmas trees, as an indispensable element of Christmas, have always garnered significant attention. With the accelerating pace of life and increasing demands for convenient decoration, modular, quickly assembleable products have become a market trend. However, traditional Christmas tree structures have several shortcomings. On one hand, the overall structure lacks an effective adjustment mechanism, making it difficult to flexibly adjust the height according to different usage scenarios and user needs, thus limiting its applicability. On the other hand, the assembly process is relatively cumbersome, with inconvenient connections between components, requiring considerable time and effort, failing to meet the expectations of modern, fast-paced lifestyles for efficient decoration. Furthermore, some Christmas tree structures suffer from poor stability, easily tipping over due to external forces during placement, posing safety hazards, and are difficult to move, causing considerable inconvenience for users. Utility Model Content

[0003] The purpose of this invention is to provide a modular Christmas tree quick assembly structure to solve the problems mentioned in the background art, such as the lack of adjustment mechanism and inconvenient assembly of existing Christmas tree structures.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The modular Christmas tree quick-assembly structure includes a modularly assembled support base and a Christmas tree trunk. The support base is conical and has a support rod coaxially connected to its top. An adjustment and positioning mechanism for adjusting the Christmas tree trunk is installed on the outer wall of the support rod. Several groups of branches are evenly and equidistantly arranged on the outer wall of the Christmas tree trunk.

[0006] The top surface of the support rod is coaxially provided with a plug groove;

[0007] The bottom of the Christmas tree trunk is coaxially fitted with a plug rod that is compatible with the cross-sectional dimensions of the plug groove and is plugged in. The plug rod has a square cross-section and several uniformly spaced vertically arranged limiting slots on its outer wall.

[0008] The adjustment and positioning mechanism includes a positioning seat and a limiting plug. The end of the limiting plug is equipped with a slide block that slides in cooperation with the inner wall of the positioning seat. The end of the slide block is coaxially connected to a pull rod, and a return spring is wound around the pull rod.

[0009] Preferably, the end of the limiting plug is arc-shaped and matches the cross-sectional dimensions of the limiting slot, allowing for a smoother insertion of the limiting plug into the limiting slot. This reduces resistance caused by sharp edges and improves assembly efficiency. Furthermore, this matching insertion method ensures a tight connection, enhancing the stability of the Christmas tree trunk after height adjustment and preventing loosening or displacement during use.

[0010] Preferably, the return spring is located between the top of the inner wall of the slide and the positioning seat. In its natural state, the spring force of the return spring can continuously act on the slide, causing the limiting plug to maintain its tendency to move towards the limiting slot. This not only ensures a tight connection between the limiting plug and the limiting slot, but also simplifies the operation when adjusting the height of the Christmas tree trunk. Simply overcome the spring force of the return spring to pull the lever, and the plug can quickly return to its original position after being released, achieving efficient height adjustment and positioning functions.

[0011] Preferably, the bottom of the support base is coaxially provided with a weight-increasing chassis, which increases the overall weight of the support base, effectively lowers the center of gravity of the Christmas tree, thereby significantly improving the stability of the Christmas tree when it is placed, reducing the risk of tipping over due to external forces (such as collisions, wind, etc.), and ensuring safe use.

[0012] Preferably, the bottom edge of the weight-adding chassis is equipped with at least three sets of uniformly spaced, ring-shaped moving wheels with fixed brakes. This not only gives the Christmas tree good mobility, making it convenient for users to move it to different locations according to actual needs, but also locks the moving wheels with fixed brakes after it has been moved to a designated location, so that the Christmas tree can be parked stably and avoids accidental movement.

[0013] Preferably, the outer wall of the Christmas tree trunk is provided with several sets of evenly spaced branch connection screw holes for installing branches, which provides a standardized connection position for the installation of branches, making the installation of branches more regular and orderly. At the same time, it also makes it easier for users to choose different positions to install branches as needed, increasing the diversity and flexibility of Christmas tree shapes.

[0014] Preferably, the end of the branch is fitted with a threaded head that matches the size of the connecting screw hole and is threadedly connected, enabling convenient connection and disassembly of the branch to the Christmas tree trunk. Users can easily complete the installation or disassembly of the branch by simply rotating it, greatly simplifying the assembly process, improving assembly efficiency, and also facilitating the replacement or maintenance of the branch.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: In this modular Christmas tree rapid assembly structure, the conical support base provides stable foundation support for the entire Christmas tree. The support rod coaxially connected to its top serves as the core support component, connecting and supporting other structures. The adjustment and positioning mechanism on the outer wall of the support rod, combined with the plug-in rod coaxially installed at the bottom of the Christmas tree trunk, ensures the directional accuracy and initial positioning of the Christmas tree trunk when connected to the support rod by having a square cross-section that matches the cross-sectional size of the plug-in slot coaxially opened on the top surface of the support rod. Several evenly spaced, vertically arranged limiting slots on the outer wall of the plug-in rod cooperate with the limiting plugs in the adjustment and positioning mechanism. Under the action of the return spring, the limiting plugs slide within the positioning seat via a slide block, enabling insertion with limiting slots of different heights, thereby flexibly adjusting the height of the Christmas tree trunk and achieving stable positioning. Simultaneously, several groups of evenly spaced branches installed on the outer wall of the Christmas tree trunk constitute the basic appearance of the Christmas tree. Through the synergistic effect of its components, the overall structure achieves rapid and stable assembly of the modular Christmas tree. Attached Figure Description

[0027] Modular Christmas tree quick-assembly structure, such as Figures 1-3As shown, the Christmas tree includes a modularly assembled support base 10 and a Christmas tree trunk 40. The support base 10 is conical in shape and has a support rod 20 coaxially connected to its top. An adjustment and positioning mechanism 30 for adjusting the Christmas tree trunk 40 is installed on the outer wall of the support rod 20. Several groups of evenly spaced branches 50 are installed on the outer wall of the Christmas tree trunk 40. A insertion slot 21 is coaxially formed on the top surface of the support rod 20. An insertion rod 41, which is adapted to the cross-sectional dimensions of the insertion slot 21 and is inserted into the bottom of the Christmas tree trunk 40, is coaxially installed. The cross-section of the insertion rod 41 is positive. The tree has a square shape with several evenly spaced, vertically arranged limiting slots 43 on its outer wall. The adjusting positioning mechanism 30 includes a positioning seat 31 and a limiting plug 32. The end of the limiting plug 32 is fitted with a slide block 33 that slides against the inner wall of the positioning seat 31. The end of the slide block 33 is coaxially connected to a pull rod 34, and a return spring 35 is wound around the pull rod 34. The supporting base 10 is conical in shape, providing stable foundation support for the entire Christmas tree. The support rod 20, coaxially connected to its top, serves as the core support component, connecting and supporting other structures. The adjusting positioning mechanism 30 on the outer wall of the support rod 20, combined with the plug-in rod 41 coaxially installed at the bottom of the Christmas tree trunk 40, has a square cross-section that matches the cross-sectional dimensions of the plug-in slot 21 coaxially opened on the top surface of the support rod 20, ensuring the directional accuracy and initial positioning when the Christmas tree trunk 40 is connected to the support rod 20. Several evenly spaced, vertically arranged limiting slots 43 on the outer wall of the plug-in rod 41 cooperate with the limiting plugs 32 in the adjusting and positioning mechanism 30. Under the action of the return spring 35, the limiting plugs 32 slide within the positioning seat 31 via the slide block 33, enabling insertion into limiting slots 43 of different heights. This allows for flexible adjustment of the height of the Christmas tree trunk 40 and stable positioning. Simultaneously, several groups of evenly spaced branches 50 installed on the outer wall of the Christmas tree trunk 40 constitute the basic appearance of the Christmas tree. Through the coordinated action of its components, the overall structure enables rapid and stable assembly of the modular Christmas tree.

[0028] Furthermore, the end of the limiting plug 32 is arc-shaped and matches the cross-sectional dimensions of the limiting slot 43, and the two are plugged in to fit together, so that the limiting plug 32 can be inserted into the limiting slot 43 more smoothly, reducing the resistance during insertion. At the same time, under the action of the return spring 35, a tighter fit can be achieved, ensuring the positioning stability of the Christmas tree trunk 40 after height adjustment.

[0029] It is worth noting that the return spring 35 is located between the top of the inner wall of the slide 33 and the positioning seat 31, so that in the natural state, the elastic force of the return spring 35 can push the slide 33, thereby keeping the limit plug 32 moving towards the insertion rod 41, ensuring that the limit plug 32 is always tightly inserted into the limit slot 43, effectively preventing the Christmas tree trunk 40 from becoming loose or sliding down during use.

[0030] Specifically, a weight-increasing base 11 is coaxially mounted on the bottom of the support base 10. At least three sets of evenly spaced, equidistant, circularly arranged casters 12 with fixed brakes are installed on the bottom edge of the weight-increasing base 11. By coaxially mounting the weight-increasing base 11 on the bottom of the support base 10, the weight of the entire support base 10 is increased, further improving the overall stability of the Christmas tree and preventing it from easily tipping over. The at least three sets of evenly spaced, equidistant, circularly arranged casters 12 with fixed brakes on the bottom edge of the weight-increasing base 11 facilitate the movement of the Christmas tree and, once moved to a suitable position, can be locked in place by the fixed brakes, ensuring the Christmas tree is stably positioned at that location.

[0031] In addition, the outer wall of the Christmas tree trunk 40 is provided with several sets of evenly spaced branch connection screw holes 42 for installing branches 50. The ends of the branches 50 are provided with threaded heads 51 that are adapted to the size of the branch connection screw holes 42 and are threadedly connected. By providing several sets of evenly spaced branch connection screw holes 42 for installing branches 50 on the outer wall of the Christmas tree trunk 40, and by providing threaded heads 51 that are adapted to the size of the branch connection screw holes 42 and are threadedly connected at the ends of the branches 50, the branches 50 and the Christmas tree trunk 40 can be easily connected and disassembled. This makes it convenient to install, replace or adjust the position of the branches 50 as needed, and improves the flexibility and convenience of Christmas tree assembly.

[0032] How this modular Christmas tree quick-assembly structure works:

[0033] First, using the movable wheels 12 on the edge of the weight-bearing chassis 11 at the bottom of the support base 10, move the Christmas tree to a suitable position and step on the fixed brake of the movable wheels 12 to fix it. Next, install the Christmas tree trunk 40 by aligning the plug rod 41 at the bottom of the Christmas tree trunk 40 with the plug slot 21 on the top surface of the support rod 20. According to the required height, pull the lever 34 in the adjusting positioning mechanism 30 to cause the slide 33 to drive the limit plug 32 to compress the return spring 35 and retract into the positioning seat 31, so that the plug rod 41 is inserted to a suitable depth. Release the lever 34, the return spring 35 rebounds, and the limit plug 32 is inserted into the limit slot 43 of the corresponding height on the plug rod 41, thereby realizing the height adjustment and fixation of the Christmas tree trunk 40.

[0034] Then install the branches 50. Align the threaded head 51 at the end of the branch 50 with the branch connecting screw hole 42 on the outer wall of the Christmas tree trunk 40, and rotate the branch 50 so that its threaded head 51 is threadedly connected to the branch connecting screw hole 42. Install all the branches 50 in sequence. In this way, a modular Christmas tree is quickly assembled and can be decorated and operated later.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
