Description

Technical Field

[0001] This utility model relates to the field of simulated tree branch connection technology, and in particular to the tree branch connection structure of simulated trees. Background Technology

[0002] With the acceleration of urbanization and the rise of the landscape decoration industry, natural trees, due to their long growth cycle and limited environmental adaptability, are unable to meet the needs of rapid and personalized scene decoration. Artificial trees, with their advantages of customization, low maintenance costs, and wide applicability, have seen continuous growth in demand. As the key part of shaping the form of artificial trees, branches need to simulate the forking angle, load-bearing capacity, and dynamic effects of natural trees. Therefore, connecting structures are needed when assembling artificial trees.

[0003] Most existing tree branch connection structures are made of different materials, and gaps are prone to appear at the connection points after long-term use, causing the branches to wobble or even fall off. In addition, some artificial trees use non-removable integrated connections to pursue initial sturdiness. If the branches are damaged, the entire trunk needs to be replaced or a large area needs to be disassembled, resulting in high maintenance costs. At the same time, the angle of artificial branches cannot be adjusted. If adjustment is needed, it can only be done by destructive disassembly, which increases rework costs.

[0004] Therefore, given that most of the aforementioned tree branch connection structures are made of different materials, gaps easily appear at the connection points after long-term use, causing the branches to wobble or even fall off. In addition, the angle of the simulated branches cannot be adjusted, and if adjustment is required, it can only be done by destructive disassembly, which increases rework costs, a tree branch connection structure for simulated trees can be designed. Utility Model Content

[0005] To overcome the problems that most tree branch connection structures are made of different materials, and gaps easily appear at the connection points after long-term use, causing the branches to wobble or even fall off, and that the angle of simulated branches cannot be adjusted, requiring destructive disassembly for adjustment, which increases rework costs, a tree branch connection structure for simulated trees is proposed.

[0006] The technical solution of this utility model is as follows: a tree branch connection structure for a simulated tree, including a connecting frame, and two sets of connecting frames are provided; a connecting component for connecting rotation is provided between the connecting frames, the connecting component includes a three-way screw joint, the three-way screw joint is provided between the connecting frames, four sets of snap-fit ​​joints are symmetrically fixedly connected to the outer side of the three-way screw joint, and snap-fit ​​grooves are opened inside both sides of the three-way screw joint.

[0007] Preferably, a connecting tube is provided at the middle position on the opposite side of the connecting frame, a fixing ring is provided on the opposite side of the connecting tube, and a snap-fit ​​spring is provided on the inner wall of the fixing ring, and two sets of snap-fit ​​springs are provided.

[0008] Preferably, a snap ring is provided on the opposite side of the snap spring, and the snap ring is located inside the fixed ring.

[0009] Preferably, a through slot is provided in the middle of the inside of the connecting frame, and the through slot corresponds to the snap-fit ​​slot.

[0010] Preferably, the connecting bracket has mounting rings at both ends near the tee connector, and the mounting rings are attached to the snap-fit ​​connector.

[0011] Preferably, the mounting ring is provided with snap rings symmetrically arranged at the center of the inner side, and the snap rings are located between the snap connector and the mounting ring.

[0012] Preferably, a sealing ring is symmetrically arranged on the opposite side of the connecting pipe, and the sealing ring is located between the fixing ring and the connecting pipe.

[0013] The beneficial effects of this utility model are as follows: The three-way rotary joint serves as a branch node, and the snap-fit ​​grooves on both sides engage with the adjacent connecting frame through a plug-in method to form the main connection path. The snap-fit ​​joint and the mounting ring are locked together by snap-fit, enabling the expansion of branches in multiple directions. The four sets of snap-fit ​​joints are centrally symmetrically distributed, which can simulate the radial growth pattern of natural tree branches and avoid messy branch distribution. The three-way structure is closer to the branching pattern of real trees, and the tight engagement of the snap-fit ​​groove and the connecting frame ensures the stability of the main trunk connection and reduces shaking. At the same time, the rotary joint design allows for a small range of adjustment of the branch angle, which can optimize the tree branch shape according to the needs of the scene.

[0020] Please see Figures 1-5This utility model provides an embodiment of a tree branch connection structure for a simulated tree, including a connecting frame 1, and the connecting frame 1 is provided with two sets; a connecting component for connecting rotation is provided between the connecting frames 1, the connecting component includes a three-way screw connector 301, the three-way screw connector 301 is provided between the connecting frames 1, four sets of snap connectors 302 are symmetrically fixedly connected to the outer center of the three-way screw connector 301, and snap slots 303 are opened inside both sides of the three-way screw connector 301.

[0021] Please see Figures 4-5 In this embodiment, a connecting pipe 2 is provided at the middle position of the connecting frame 1 on the opposite side, a fixing ring 304 is provided on the opposite side of the connecting pipe 2, a snap-fit ​​spring 305 is provided on the inner wall of the fixing ring 304, and two sets of snap-fit ​​springs 305 are provided; a snap-fit ​​ring 306 is provided on the opposite side of the snap-fit ​​spring 305, and the snap-fit ​​ring 306 is located inside the fixing ring 304; a through groove 307 is opened at the middle position inside the connecting frame 1, and the through groove 307 corresponds to the snap-fit ​​groove 303.

[0022] Two sets of snap-fit ​​springs 305 on the inner wall of the fixing ring 304 exert symmetrical forces on the snap-fit ​​ring 306. When a branch is inserted into the snap-fit ​​ring 306, the elastic potential energy of the snap-fit ​​springs 305 will press the snap-fit ​​ring 306 tightly against the outer wall of the branch, forming a stable snap-fit ​​effect and reducing the risk of the branch loosening or falling off due to external force. The corresponding design of the through groove 307 and the snap-fit ​​groove 303 further ensures the alignment accuracy of the connection parts, avoids unstable connection due to installation deviation, and enhances the load-bearing capacity and anti-interference of the overall structure. The snap-fit ​​springs 305 have a certain amount of extension and contraction margin, so that the inner diameter of the snap-fit ​​ring 306 can be adjusted within a certain range, which can adapt to branches of different thicknesses. There is no need to design a separate connection structure for branches of specific specifications, which increases versatility and reusability.

[0023] Please see Figures 2-3 In this embodiment, both ends of the connecting frame 1 near the three-way swivel joint 301 are provided with mounting rings 308, and the mounting rings 308 are connected to the snap-fit ​​joint 302; the mounting rings 308 are symmetrically arranged with snap-fit ​​rings 309 inside, and the snap-fit ​​rings 309 are disposed between the snap-fit ​​joint 302 and the mounting rings 308; the connecting pipe 2 is symmetrically arranged with sealing rings 310 on the opposite side, and the sealing rings 310 are disposed between the fixing ring 304 and the connecting pipe 2.

[0024] The mounting ring 308 engages with the snap-fit ​​connector 302 via the snap-fit ​​ring 309. The snap-fit ​​ring 309 adopts a centrally symmetrical layout, which can evenly distribute the force on the branches and avoid excessive force on a single point, which could lead to loosening or detachment. The tee screw connector 301, as a branch node, combined with the fixing function of the connecting frame 1, can simultaneously stabilize multiple branches, ensuring that the overall structure is not easily deformed during long-term use. The sealing ring 310 between the connecting pipe 2 and the fixing ring 304 not only enhances the tightness of the connection but also reduces frictional wear between components. It also prevents dust, moisture, etc. from entering the internal structure, avoiding rust on metal components or aging of plastic components, indirectly improving connection stability. The presence of the sealing ring 310 reduces direct contact wear between the connecting pipe 2 and the fixing ring 304 and isolates it from external environmental corrosion. The snap-fit ​​ring 309 can buffer the impact force generated by the shaking of branches, reduce component fatigue wear, and extend the service life of the overall structure.

[0025] Place the two sets of connecting brackets 1 on both sides of the tee joint 301, ensuring that the mounting ring 308 on the side of the connecting bracket 1 closest to the tee joint 301 is aligned with the retaining connector 302 on the outside of the tee joint 301. Then push the connecting bracket 1 so that the mounting ring 308 is fitted into the retaining connector 302. At this time, the retaining ring 309 inside the mounting ring 308 will naturally embed into the gap between the retaining connector 302 and the mounting ring 308, initially limiting the relative sliding of the two with the help of friction, thus completing the initial fixation of the connecting bracket 1 and the tee joint 301. When the mounting ring 308 is fully fitted into the retaining connector 302, the connecting bracket 1 and the tee joint 301 are fixed. This creates a rotatable connection, which facilitates subsequent adjustment of the branch angle. After installation, the simulated branch is inserted between the snap rings 306 inside the connecting tube 2. During this process, the snap spring 305 is compressed, and the rebound force of the snap spring 305 will firmly fix the simulated branch. At the same time, the bottom end of the simulated branch will be snapped into the through groove 307, further enhancing the connection stability. Finally, when the connecting tube 2 and the fixing ring 304 are connected, the sealing ring 310 on the opposite side of the connecting tube 2 will be squeezed between the fixing ring 304 and the connecting tube 2. The elastic deformation of the sealing ring 310 can fully fill the gap, effectively enhancing the sealing of the connection.
