Modularly spliced simulation branch stem connection structure

Abstract

This utility model discloses a modular splicing connection structure for simulated tree branches, including a simulated tree body, branch bodies mounted on the simulated tree body, and support components disposed within the simulated tree body and branch bodies. By aligning the fixed trapezoidal block and sliding trapezoidal block of the branch body with the circular groove of the simulated tree body, the fixed trapezoidal block, when in contact with the inclined plate of the locking block, causes the locking block to slide outward and compress the first spring. After the fixed trapezoidal block passes through, the first spring causes the locking block to lock between the fixed trapezoidal block and the sliding trapezoidal block, achieving rapid installation of the branch body without the need for additional tools, simplifying the operation process. At the same time, the compressed second spring causes the abutment rod to abut against the simulated tree body, making the locking block and the end of the fixed trapezoidal block near the sliding trapezoidal block fit tightly, enhancing the stability of the connection, effectively preventing loosening, significantly improving the efficiency of modular splicing, and increasing the convenience of splicing.

Description

Technical Field

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

[0002] With social development, material products have become much more abundant, and people have more time and energy to consider the improvement of their spiritual and cultural life. As a result, more and more people are beginning to pay attention to beautifying their surrounding living environment. Currently, many cities are starting to use artificial trees for beautification. Artificial trees, also known as man-made trees, are products designed and manufactured by humans to imitate the shape, texture, color, and other characteristics of natural trees. They are not naturally growing plants, but are made using various materials (such as plastics, resins, fibers, metals, and wood) through multiple processes such as molding, hand carving, and coloring. The aim is to achieve a visually realistic effect, while also possessing more stable performance and a wider range of applications than natural trees. This not only completely changes the limitations of region and climate on tree species, but also makes them easy to manage, requiring no watering, fertilization, or additional care.

[0003] In existing technologies, artificial trees are manufactured separately from the trunk to facilitate the transport and installation of artificial landscape trees. After the artificial landscape tree is transported to the customer's installation site, the branches and trunk are assembled together. However, since the connection between the branches and trunk is usually fixed by external bolts and nuts, each bolt needs to be tightened with tools during installation, which is cumbersome and time-consuming. Especially for trees with many branches, the assembly efficiency is extremely low. Therefore, it is necessary to improve the modular splicing artificial tree branch and trunk connection structure to solve the above problems. Utility Model Content

[0004] To overcome the problem that existing simulated tree branches and trunks are fixed with external bolts and nuts, requiring tools to tighten them one by one during installation, which is cumbersome, time-consuming, and results in low assembly efficiency.

[0005] The technical solution of this utility model is as follows: a modular splicing simulated tree branch connection structure, including a simulated tree body, a branch body disposed on the simulated tree body, a support component disposed inside the simulated tree body and the branch body, an optical axis fixedly connected to one end of the branch body near the simulated tree body, a fixed trapezoidal block fixedly connected to one end of the optical axis away from the branch body, a sliding trapezoidal block slidably connected to the optical axis, a guide block fixedly connected to one end of the sliding trapezoidal block near the fixed trapezoidal block, a locking block slidably connected inside the simulated tree body, a first sliding rod fixedly connected to the outside of the locking block, and a first spring fixedly connected between the first sliding rod and the simulated tree body. The guide block is slidably connected to the optical axis, the first sliding rod is slidably connected to the inside of the simulated tree body, and the locking block is driven to slide by the first spring.

[0006] Preferably, the simulated tree body has a matching groove at the corresponding position of the first sliding rod, and the first sliding rod slides inside the groove of the simulated tree body.

[0007] Preferably, the simulated tree body has a matching groove at the corresponding position of the card block, and the card block slides inside the groove of the simulated tree body.

[0008] Preferably, the simulated tree body has matching circular grooves at corresponding positions of the fixed trapezoidal block and the sliding trapezoidal block, and the fixed trapezoidal block and the sliding trapezoidal block are set inside the circular grooves of the simulated tree body.

[0009] Preferably, the end of the card block near the sliding trapezoidal block is set as a ramp.

[0010] Preferably, an elastic protective cover is fixedly connected to one end of the branch body near the simulated tree body, and a support frame is fixedly connected to one end of the elastic protective cover near the simulated tree body. The support frame is in contact with the simulated tree body. An outer frame is fixedly connected to one end of the fixed trapezoidal block away from the sliding trapezoidal block. A support rod is slidably connected inside the outer frame. The support rod is in contact with the simulated tree body. A second spring is fixedly connected between the support rod and the outer frame.

[0011] Preferably, the outer frame has a matching groove at the corresponding position of the abutment, and the abutment slides inside the groove of the outer frame.

[0012] Preferably, the support assembly includes a first metal support frame fixedly connected inside the simulated tree body and a second metal support frame fixedly connected inside the branch body.

[0013] The beneficial effects of this utility model are:

[0014] 1. By aligning the fixed trapezoidal block and the sliding trapezoidal block of the branch body with the circular groove of the simulated tree body, the fixed trapezoidal block slides outward and compresses the first spring when it contacts the inclined plate. After the fixed trapezoidal block passes through, the first spring causes the plate to lock between the fixed trapezoidal block and the sliding trapezoidal block, realizing the rapid installation of the branch body without the need for additional tools, simplifying the operation process. At the same time, the compressed second spring causes the abutment rod to abut against the simulated tree body, so that the plate and the end of the fixed trapezoidal block near the sliding trapezoidal block fit tightly, enhancing the stability of the connection, effectively preventing loosening, significantly improving the efficiency of modular splicing, and improving the convenience of splicing.

[0015] 2. By setting up the first and second metal support inner frames, the overall structural strength and deformation resistance of the simulated tree body and branches can be significantly improved, making it less prone to bending or breaking when subjected to external forces (such as wind, collisions, or heavy loads). This ensures that the modularly assembled simulated tree can adapt to different usage environments and extend its service life. At the same time, the rigid support of the metal inner frames also provides a stable installation foundation for the connecting components, ensuring that the fitting accuracy of the connecting parts is not affected by the deformation of the body.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 5This utility model provides an embodiment of a modular splicing simulated tree branch connection structure, including a simulated tree body 1, and branch bodies 4 disposed on the simulated tree body 1, a support component disposed inside the simulated tree body 1 and branch bodies 4, an optical axis 23 fixedly connected to one end of the branch body 4 near the simulated tree body 1, a fixed trapezoidal block 26 fixedly connected to one end of the optical axis 23 away from the branch body 4, a sliding trapezoidal block 24 slidably connected to the optical axis 23, a guide block 25 fixedly connected to one end of the sliding trapezoidal block 24 near the fixed trapezoidal block 26, a locking block 27 slidably connected inside the simulated tree body 1, a first sliding rod 28 fixedly connected to the outside of the locking block 27, and a first spring 29 fixedly connected between the first sliding rod 28 and the simulated tree body 1. The guide block 25 is slidably connected to the optical axis 23, and the first sliding rod 28 is slidably connected inside the simulated tree body 1. The locking block 27 is slidably moved by the first spring 29. By aligning the fixed trapezoidal block 26 and the sliding trapezoidal block 24 of the branch body 4, the simulated tree structure is achieved. The circular groove of the tree body 1 utilizes the contact of the fixed trapezoidal block 26 with the inclined plate 27 to drive the plate 27 to slide outward and compress the first spring 29. After the fixed trapezoidal block 26 passes through, the first spring 29 drives the plate 27 to lock between the fixed trapezoidal block 26 and the sliding trapezoidal block 24, realizing the rapid installation of the branch body 4 without the need for additional tools, simplifying the operation process. At the same time, the compressed second spring 212 drives the abutment rod 211 to abut against the simulated tree body 1, so that the plate 27 and the end of the fixed trapezoidal block 26 near the sliding trapezoidal block 24 fit tightly, enhancing the stability of the connection, effectively preventing loosening, significantly improving the efficiency of modular splicing, and improving the convenience of splicing. The support component, by setting the first metal support inner frame 31 and the second metal support inner frame 32, can significantly improve the overall structural strength and deformation resistance of the simulated tree body 1 and the branch body 4, and extend their service life. At the same time, the rigid support of the metal inner frame also provides a stable installation foundation for the connecting components, ensuring that the fitting accuracy of the connection parts is not affected by the deformation of the body.

[0024] Please see Figure 2 - Figure 4In this embodiment, the simulated tree body 1 has a matching groove at the corresponding position of the first sliding rod 28. The first sliding rod 28 slides inside the groove of the simulated tree body 1. By setting a groove on the simulated tree body 1 that matches the first sliding rod 28, the sliding trajectory of the first sliding rod 28 can be precisely limited, preventing it from falling out of the simulated tree body 1. This ensures that the first sliding rod 28 can drive the locking block 27 to complete the extension and retraction action stably and smoothly, thereby ensuring the matching accuracy of the locking block 27 with the fixed trapezoidal block 26 and the sliding trapezoidal block 24. The simulated tree body 1 has a matching groove at the corresponding position of the locking block 27, and the locking block 27 slides inside the groove of the simulated tree body 1. By setting a matching groove on the locking block 27... The sliding groove effectively constrains the sliding direction and range of the locking block 27, ensuring that the locking block 27 always moves along a preset trajectory. This ensures that it can accurately slide outward when the fixed trapezoidal block 26 passes through and precisely lock between the fixed trapezoidal block 26 and the sliding trapezoidal block 24 when the first spring 29 returns to its original position. This further enhances the stability of the splicing structure and the success rate of installation. The simulated tree body 1 has matching circular grooves at corresponding positions of the fixed trapezoidal block 26 and the sliding trapezoidal block 24. The fixed trapezoidal block 26 and the sliding trapezoidal block 24 are set inside the circular grooves of the simulated tree body 1. By setting circular grooves that match the fixed trapezoidal block 26 and the sliding trapezoidal block 24, a precise installation positioning reference can be provided for both, ensuring that they can be quickly inserted into the simulated tree body 1. The quick alignment reduces the alignment time during installation. Simultaneously, the circular groove provides a wrapping support for the fixed trapezoidal block 26 and the sliding trapezoidal block 24, distributing the stress at the connection points and preventing excessive local stress that could damage components, thus extending the structure's lifespan. The end of the locking block 27 near the sliding trapezoidal block 24 is designed as a ramp. This ramp guides the fixed trapezoidal block 26 during insertion, making the contact between the fixed trapezoidal block 26 and the locking block 27 smoother and reducing insertion resistance. The locking block 27 can be pushed outwards without additional force, reducing installation difficulty and allowing operators to more easily connect the branch body 4, improving installation efficiency. The branch body 4 is close to the simulated tree body 1. One end of the structure is fixedly connected to an elastic protective cover 21. A support frame 22 is fixedly connected to the end of the elastic protective cover 21 closest to the simulated tree body 1, and the support frame 22 is in contact with the simulated tree body 1. An outer frame 210 is fixedly connected to the end of the fixed trapezoidal block 26 furthest from the sliding trapezoidal block 24. A support rod 211 is slidably connected inside the outer frame 210, and the support rod 211 is in contact with the simulated tree body 1. A second spring 212 is fixedly connected between the support rod 211 and the outer frame 210. By setting the elastic protective cover 21 and the support frame 22, the connection gap between the branch body 4 and the simulated tree body 1 can be blocked, concealing internal components and improving the realism of the simulated tree's appearance. Simultaneously, the elastic protective cover 21 can deform with slight shaking of the branch body 4, preventing damage to the connection points due to friction.Through the cooperation of the outer frame 210, the abutment 211, and the second spring 212, the elastic force of the second spring 212 ensures that the abutment 211 always abuts against the simulated tree body 1. This, in turn, transmits force to ensure that the locking block 27 tightly adheres to and fixes the trapezoidal block 26, preventing the locking block 27 from loosening and enhancing the stability of the connection. The outer frame 210 has a matching groove at the corresponding position of the abutment 211. The abutment 211 slides within the groove of the outer frame 210. By providing a matching groove for the abutment 211, it is ensured that the abutment 211 slides smoothly in a straight line under the action of the second spring 212, preventing the abutment 211 from tilting or jamming. This ensures that it always accurately abuts against the simulated tree body 1, effectively transmitting the elastic force of the second spring 212, thereby continuously providing pressure for the locking block 27 to adhere to and fix the trapezoidal block 26, maintaining the long-term stability of the connection structure.

[0025] Please see Figure 5 In this embodiment, the support component includes a first metal support inner frame 31 fixedly connected inside the simulated tree body 1 and a second metal support inner frame 32 fixedly connected inside the branch body 4. By setting the first metal support inner frame 31 and the second metal support inner frame 32, the overall structural strength and deformation resistance of the simulated tree body 1 and the branch body 4 can be significantly improved, making it less prone to bending or breaking when subjected to external forces (such as wind, collision or hanging heavy objects). This ensures that the modularly assembled simulated tree can adapt to different usage environments and extend its service life. At the same time, the rigid support of the metal inner frame also provides a stable installation foundation for the connecting components, ensuring that the fitting accuracy of the connecting parts is not affected by the deformation of the body.

[0026] In use, first align the fixed trapezoidal block 26 and the sliding trapezoidal block 24 on the branch body 4 with the circular groove on the simulated tree body 1 and insert them. During insertion, the fixed trapezoidal block 26 pushes the locking block 27 outward along its groove through the sloping end of the locking block 27, while simultaneously driving the first sliding rod 28 to slide along its groove and compressing the first spring 29. When the fixed trapezoidal block 26 is fully inserted, the first spring 29 returns to its original position and drives the locking block 27 and the first sliding rod 28 back, so that the locking block 27 is locked between the fixed trapezoidal block 26 and the sliding trapezoidal block 24 to achieve initial fixation. At the same time, the second spring 212 compressed inside the outer frame 210 pushes the abutment rod 211 to slide along its groove and abut against the simulated tree body 1. This force makes the locking block 27 and the fixed trapezoidal block 26 fit tightly to enhance the fixation effect. When disassembling, by pressing the branch body 4, the sliding trapezoidal block 24 is driven to contact the slope of the locking block 27, and the locking block 27 is slid outward. The first spring 29 is compressed as the sliding trapezoidal block 24 passes through it. Due to the slope of the sliding trapezoidal block 24, the compressed first spring 29 drives the locking block 27 to clamp the sliding trapezoidal block 24. Then, the branch body 4 is pushed outward. At this time, the clamped sliding trapezoidal block 24 slides towards the fixed trapezoidal block 26, so that it contacts the fixed trapezoidal block 26. The guide block 25 is stored inside the fixed trapezoidal block 26, and the limiting of the locking blocks 27 on both sides is released, so that the branch body 4 can be easily removed. The first metal support frame 31 inside the simulated tree body 1 and the second metal support frame 32 inside the branch body 4 provide rigid support for the overall structure. The elastic protective cover 21 and the abutment 22 at the end of the branch body 4 cover the connection gap after installation and adapt to deformation with slight shaking, thereby realizing the convenient, stable and beautiful modular splicing of the branch body 4 and the simulated tree body 1.

[0027] Through the above steps, by aligning the fixed trapezoidal block 26 and the sliding trapezoidal block 24 of the branch body 4 with the circular groove of the simulated tree body 1, when the fixed trapezoidal block 26 contacts the inclined plate 27, it drives it to slide outward and compress the first spring 29. After passing through, the first spring 29 makes the plate 27 lock between the fixed trapezoidal block 26 and the sliding trapezoidal block 24, thus realizing the quick installation of the branch body 4 without the need for additional tools and simplifying the process. At the same time, the compressed second spring 212 drives the abutment rod 211 to abut against the simulated tree body 1, so that the plate 27 and the fixed trapezoidal block 26 fit tightly, enhancing stability and preventing loosening. This significantly improves the modular splicing efficiency and convenience, thus solving the problem that the existing simulated tree branches and trunks are fixed with external bolts and nuts, which require tools to tighten them one by one during installation, resulting in cumbersome and time-consuming operation and low assembly efficiency.
