Description

Technical Field

[0001] This utility model relates to the field of artificial trees, and in particular to a quick-change snap-fit ​​structure for artificial tree leaves. Background Technology

[0002] Artificial trees are characterized by their beautiful shapes and high plasticity, which can quickly create landscapes and unique atmospheres. They are easy to maintain, require no watering or fertilization, adapt to various environments, are wind-resistant, flame-retardant, and environmentally friendly. They can enhance the theme of scenic spots, improve taste, decorate commercial and residential spaces, and even serve as equipment shelters. Combining aesthetics and practicality, they are an ideal choice for greening and decoration.

[0003] Traditional artificial trees mostly use fixed connections between leaves and trunks, such as glue or bolts. When using glue, after a long period of use, the glue will gradually age and fail due to factors such as environmental humidity, temperature changes, and ultraviolet radiation, causing leaves to loosen or even fall off. Moreover, due to the strong bond of glue, it is difficult to completely remove old leaves. Forcible removal often damages the surface of the trunk, seriously affecting the overall aesthetics and lifespan of the artificial tree.

[0004] Using bolts for fastening also has drawbacks. Special tools such as wrenches must be used when installing and removing blades, making the process cumbersome and inefficient. This is especially true when a large number of blades need to be replaced, as it consumes a lot of time and manpower. Utility Model Content

[0005] To overcome the problems of adhesive bonding being susceptible to aging and failure due to environmental influences, causing blades to loosen and fall off, making complete disassembly difficult and damaging the main trunk, and bolt fastening, installation, and disassembly requiring special tools, which are cumbersome and inefficient.

[0006] The technical solution of this utility model is as follows: a quick-change snap-fit ​​structure for simulated leaf blades, including a basin for support and a main stem fixedly installed inside the basin and extending along its axial direction. On the outer wall surface of the main stem distributed circumferentially, multiple fixed bases are fixedly connected at intervals along the axis of the main stem. Each fixed base has a cavity inside, which contains a linearly displaceable connecting module. The upper and lower surfaces of the fixed base are respectively provided with guide grooves penetrating the cavity. The extension direction of the guide grooves is perpendicular to the axis of the main stem and is adapted to the movement trajectory of the connecting module. The blade unit is detachably connected to the fixed base through the connecting module. The connecting module moves linearly within the path defined by the guide groove to perform elastic locking and releasing of the blade unit, completing the disassembly and assembly of the blade unit on the fixed base.

[0007] Preferably, the connecting module includes an integrally fixed support plate in the cavity, a spring is provided on the surface of the support plate, a through hole is provided at the end of the fixed base facing the spring, a button adapted to the through hole is provided at the output end of the spring, and a slider adapted to the guide groove is fixed to the outer wall of the button. By pressing the button, the spring drives the slider to move in the guide groove.

[0008] Preferably, the blade unit includes a card holder, which has an integrally formed bent portion adapted to the slider. The card holder has a slot at one end of the button, and the back of the card holder is fixedly connected to the simulated leaf body.

[0009] Preferably, a locking hole is provided at the end of the bent part facing the slider, and a locking block that matches the locking hole is integrally fixed to the outer wall of the slider, with the locking block inserted into the locking block.

[0010] Preferably, permanent magnets are provided on the contact surfaces of the locking block and the locking hole, and the locking block and the locking hole are magnetically connected.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5This utility model provides an embodiment of a quick-change snap-fit ​​structure for simulated leaf blades, including a basin 1 for support and a main stem 2 fixedly disposed inside the basin 1 and extending along its axial direction. On the outer wall surface of the main stem 2 distributed circumferentially, a plurality of fixed bases 3 are fixedly connected and spaced apart along the axial direction of the main stem 2. Each fixed base 3 has a cavity 4 inside, and the cavity 4 contains a connecting module that can be linearly displaced. The upper and lower surfaces of the fixed base 3 are respectively provided with guide grooves 5 that penetrate the cavity 4. The extension direction of the guide grooves 5 is perpendicular to the axis of the main stem 2 and is adapted to the movement trajectory of the connecting module. The leaf unit is detachably connected to the fixed base 3 through the connecting module. The connecting module moves linearly within the path defined by the guide groove 5 to perform elastic locking and releasing of the blade unit, completing the assembly and disassembly of the blade unit on the fixed base 3. The pot 1, as the basic load-bearing component of the entire simulated tree, provides support and a stable installation platform for the trunk 2, ensuring its stable placement within the pot 1 and guaranteeing the overall stability of the simulated tree structure. The trunk 2 is the supporting structure of the simulated tree, simulating the shape of a real tree trunk. The fixed base 3 is fixedly connected to the circumferentially distributed outer wall surface of the trunk 2 and is spaced apart along the axis of the trunk 2. This distribution allows the blade units to be installed at different heights and positions on the trunk 2. The assembly and disassembly of the blade unit simulates the distribution of leaves on a real tree, making the simulated tree look more natural and realistic. The guide groove 5 restricts the movement direction of the connecting module, ensuring it can only move linearly within its defined path. This guarantees smooth assembly and disassembly of the blade unit. When installing a blade unit, the connecting module elastically locks it, firmly fixing it to the fixed base 3. When disassembling the blade unit, the connecting module moves in the opposite direction, releasing the elastic lock and allowing for rapid assembly and disassembly of the blade unit on the fixed base 3. This elastic locking and releasing design makes blade unit replacement more convenient. The design is quick and efficient, improving the maintenance and use efficiency of the artificial tree. The leaf unit is connected to the fixed base 3 through the connecting module, forming a detachable connection. It is the main decorative component of the artificial tree, simulating the leaf shape of real trees. The shape, color and material of the leaf unit can be designed according to different simulation needs to achieve a realistic visual effect. The detachable connection design makes it easy to replace the leaf unit. When the leaf unit is damaged, aged or needs to be replaced with a different style of leaf, the operator can quickly remove the leaf unit from the fixed base 3 and install a new leaf unit without having to disassemble and reassemble the entire artificial tree on a large scale, reducing maintenance costs and difficulty.

[0023] Please see Figure 2 - Figure 4In this embodiment, the connecting module includes a support plate 6 integrally fixed in the cavity 4. A spring 7 is provided on the surface of the support plate 6. A through hole is provided at the end of the fixing base 3 facing the spring 7. A button 9 adapted to the through hole is provided at the output end of the spring 7. A slider 10 adapted to the guide groove 5 is fixed to the outer wall of the button 9. By pressing the button 9, the spring 7 drives the slider 10 to move in the guide groove 5. The blade unit includes a card holder 11. A bent part 12 adapted to the slider 10 is integrally provided on the card holder 11. A slot 13 is provided at the end of the card holder 11 located at the button 9. The back of the 11 is fixedly connected to the simulated leaf body 14. The bent part 12 has a locking hole 15 at the end facing the slider 10. The outer wall of the slider 10 is integrally fixed with a locking block 16 that matches the locking hole 15. The locking block 16 is inserted into the locking block 16. The contact surfaces of the locking block 16 and the locking hole 15 are provided with permanent magnets, and the locking block 16 and the locking hole 15 are magnetically connected. The support plate 6 is integrally fixed in the cavity 4, providing a mounting base for the spring 7. The spring 7 is elastic and can undergo elastic deformation when subjected to external force, and return to its original shape after the external force is removed. The spring 7 serves as a connector. The module's power component uses its elastic force to move and reset the slider 10. When the blade unit needs to be disassembled, the operator presses button 9. After being pressed, button 9 moves inward into the fixed base 3, compressing spring 7 and simultaneously moving slider 10 within the guide groove 5. This ensures that slider 10 can accurately separate from or engage with the blade unit's mounting bracket 11. When button 9 is released, spring 7 returns to its original shape under its own elastic force, pushing button 9 and slider 10 to move in opposite directions, returning to their initial positions. The bent portion 12 provides a space for slider 10 to insert and lock. The slot 13 allows operators to press button 9 when disassembling the blade unit. Permanent magnets are provided on the contact surfaces of locking block 16 and locking hole 15. Through the magnetic connection of the permanent magnets, locking block 16 can be firmly attracted into locking hole 15, realizing a stable connection between slider 10 and bending part 12, thereby fixing the blade unit on the fixed base 3. This magnetic connection method is not only firmly connected, but also easy to disassemble. Operators only need to press button 9 to overcome the magnetic force of permanent magnets, so that locking block 16 can be removed from locking hole 15, completing the disassembly of blade unit.

[0024] Please see Figure 5In this embodiment, a column 17 is detachably installed on the upper end of the trunk 2. An extension rod 18 is provided on the outer wall of the column 17. An ambient light 19 with a built-in power supply is provided at the end of the extension rod 18. A plug rod 20 is fixedly connected to the lower end of the column 17. A plug hole 21 is opened at the upper end of the trunk 2. The plug rod 20 is inserted into the plug hole 21. This plug-in connection method allows the column 17 to be easily installed on the trunk 2, and it is also easy to disassemble and replace. When it is necessary to replace the column 17 or maintain the trunk 2, the operator only needs to pull the plug rod 20 out of the plug hole 21 to remove the column 17 from the trunk 2. The extension rod 18 serves to support and fix the ambient light 19, so that the ambient light 19 can be installed in a suitable position. The ambient light 19 is powered by a built-in power supply and emits light, which can provide a decorative effect for the artificial tree at night or in occasions where an atmosphere needs to be created, enhancing the ornamental value and interest of the artificial tree.

[0025] Working principle: When the blade unit is found to be damaged or aged, or when different styles of blades need to be replaced due to scene changes, the operator inserts his finger into the slot 13 on the blade unit holder 11 and presses the button 9 evenly. After being pressed, the button 9 moves into the fixed base 3, compressing the spring 7 on the support plate 6. At the same time, it drives the slider 10, which is fixed to the outer wall of the button 9, to move along the guide groove 5. The locking block 16 on the outer wall of the slider 10 then exits from the locking hole 15 of the bending part 12, overcoming the magnetic force of the permanent magnet on the contact surface of the locking block 16 and the locking hole 15, thus releasing the blade unit. At this time, the old blade unit can be easily removed from the fixed base 3.

[0026] Next, select a new suitable blade unit, align the bent part 12 of its holder 11 with the position of the slider 10 on the fixed base 3, align the slot 13 of the holder 11 with the button 9, press the button 9 again, so that the slider 10 moves a certain distance under the compression of the spring 7, then bring the holder 11 close to the fixed base 3, release the button 9, the spring 7 returns to its original shape under its own elastic force, push the button 9 and the slider 10 to move in opposite directions, the locking block 16 on the slider 10 is inserted into the locking hole 15 of the bent part 12, and a firm magnetic connection is achieved through the permanent magnet, thus completing the installation of the new blade unit on the fixed base 3;

[0027] To install or replace the ambient light 19, the operator holds the column 17, aligns the insert 20 at the lower end of the column 17 with the socket 21 at the upper end of the main column 2, and slowly and steadily inserts the insert 20 into the socket 21, ensuring a tight and secure connection. At this time, the ambient light 19 at the end of the extension rod 18 on the outer wall of the column 17 is supported and fixed in a suitable position through the extension rod 18. To replace the column 17 or perform maintenance on the main column 2, simply hold the column 17 with your hand, gently pull it upwards, and pull the insert 20 out of the socket 21 to remove the column 17 from the main column 2.

[0028] Through the above steps, with the help of the connecting module and the guide slide 5, pressing the button 9 can realize the quick elastic locking and releasing of the blade unit on the fixed base 3 to complete the disassembly and assembly, which greatly improves the replacement efficiency and solves the problems of glue being easily affected by the environment and aging and failing, causing the blades to loosen and fall off, which is difficult to completely disassemble and will damage the main trunk 2. The bolt fastening and disassembly require special tools, which is cumbersome and inefficient.
