Description

Technical Field

[0001] This invention relates to the field of tree growth fixing devices, specifically to a tree growth fixing device and fixing method with the function of preventing trees from falling over. Background Technology

[0002] Trees play a vital role in landscaping, roadside greening, and ecological restoration projects. Newly transplanted trees, or those growing in windy areas or with soft soil, are highly susceptible to tilting or even falling due to unstable root systems or insufficient soil grip. Falling trees not only lead to tree death and economic losses but can also injure pedestrians, damage vehicles, or disrupt traffic, posing significant safety hazards. Therefore, effective tree stabilization and support are crucial aspects of tree maintenance.

[0003] However, existing tree anchoring devices typically employ simple triangular support frames or single upright posts. When in use, the connection between the support rod and the base or trunk contact point is often rigidly fixed or simply hinged, limiting the range of adjustment. For trunks with different growth postures (such as tilted growth or special branching positions), it is difficult to achieve multi-dimensional angle fine-tuning, resulting in the support point not precisely fitting the optimal stress position on the trunk, easily causing instability or damage to the bark. Furthermore, existing anchoring devices are mostly used independently. When constructing a more integrated support system such as a ring or polygonal structure for large trees or special terrain, additional binding straps, wires, or complex auxiliary tools are often required for manual connection. This method is not only inefficient and cumbersome to install, but also results in poor stability at the connection points, making it difficult to form a unified stress-bearing structure and limiting its resistance to tipping. Summary of the Invention

[0004] The present invention aims to address the shortcomings of the prior art by providing a tree growth fixing device and method with anti-tree-falling function. To solve the above problems, by adjusting the settings of the components, it can accurately support tree trunks with different growth postures, improve the adaptability of the device to complex tree shapes, and by setting up modular components, it can realize the rapid splicing of multiple fixing devices, expanding a single unit into a ring or polygonal support system, thereby enhancing the stability and expandability of the overall structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tree growth fixing device with anti-tree-falling function, comprising: multiple base plates, with support plates fixedly connected to the top of the multiple base plates; an adjustment assembly disposed on one side of the multiple support plates; the adjustment assembly comprising: a fixing seat fixedly connected to one side of the multiple support plates; a limiting groove formed on one side of the fixing seat; a steel ball rotatably connected inside the limiting groove; two rubber blocks disposed inside the limiting groove; two bolts disposed on the outside of the fixing seat; a threaded rod welded to the outside of the steel ball; an adjustment sleeve sleeved on the outside of the threaded rod; a top block fixedly connected to one end of the adjustment sleeve; and a modular assembly disposed between the multiple base plates.

[0009] Furthermore, a pull tab a is provided on one side of the base plate, a pull tab b is provided on one side of the pull tab a, and two sleeves are fixedly connected to one side of the pull tab a.

[0010] Furthermore, both pull tab a and pull tab b have limit slots on one side, and rotating shafts are inserted inside the two sleeves.

Secondly, by setting up modular components, multiple fixing devices can be quickly spliced ​​together by using the cooperation of springs, limit rods, rods, pull tabs a and b, expanding the single unit into a ring or polygonal support system, thereby enhancing the stability and expandability of the overall structure. Next, by setting up the fixing components, the ground nails at the bottom of the base plate and the inserts in the diagonal brace can be combined to form a double ground anchorage, and the angle of the diagonal brace into the soil can be adjusted by rotating the connector to improve the stability of the fixing device.

[0029] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figure 1-10 This embodiment provides a tree-fixing device with anti-tipping function, comprising: multiple base plates 1, with support plates 2 fixedly connected to the top of the multiple base plates 1; an adjustment assembly disposed on one side of the multiple support plates 2, the adjustment assembly comprising: a fixing seat 4 fixedly connected to one side of the multiple support plates 2, a limiting groove 401 formed on one side of the fixing seat 4, a steel ball 404 rotatably connected inside the limiting groove 401, two rubber blocks 403 disposed inside the limiting groove 401, two bolts 406 disposed on the outside of the fixing seat 4, a threaded rod 405 welded to the outside of the steel ball 404, an adjustment sleeve 5 sleeved on the outside of the threaded rod 405, and a top block 501 fixedly connected to one end of the adjustment sleeve 5; and a modular assembly disposed between the multiple base plates 1, the modular assembly comprising: a support plate 2 inner... The support plate 2 has a spring cavity 6, inside which is a limiting rod 604. A spring 601 is sleeved on the outside of the limiting rod 604. Two slots 7 are opened on one side of the support plate 2. A rod 702 is inserted into the two slots 7. Two sliders 705 are provided on the outside of the rod 702. A fixing assembly is set on one side of the multiple base plates 1. The fixing assembly includes: a U-shaped limiting rod 201 is fixedly connected to one side of the support plate 2. Two limiting blocks 202 are fixedly connected to the outside of the U-shaped limiting rod 201. A connector 203 is rotatably connected to the outside of the limiting blocks 202. A diagonal brace 3 is fixedly connected to one end of the connector 203. A telescopic groove 301 is opened inside the diagonal brace 3. A pin 306 is slidably connected inside the telescopic groove 301. Four ground nails 101 are fixedly connected to the bottom of the multiple base plates 1.

[0031] Among them, by adjusting the settings of the components, the rotation of the steel ball 404 in the limiting groove 401, combined with the clamping and limiting of the rubber block 403, can realize the multi-dimensional flexible adjustment of the angle between the threaded rod 405 and the top block 501, which is convenient to provide precise support for tree trunks with different growth postures and improve the adaptability of the device to complex tree shapes. Secondly, by setting up modular components, the combination of spring 601, limit rod 604, rod 702, pull tab a8 and pull tab b9 can realize the rapid splicing of multiple fixing devices, expanding the single unit into a ring or polygonal support system, and enhancing the stability and expandability of the overall structure. Next, by setting up the fixing components, the ground nails 101 at the bottom of the base plate 1 and the inserts 306 in the diagonal brace 3 can form a double ground anchorage. The angle of the diagonal brace 3 into the ground can be adjusted by rotating the connector 203, thereby improving the stability of the fixing device. Two bolts 406 are connected to two rubber blocks 403 respectively. Two storage slots 402 are opened on both sides inside the limiting groove 401. An adjusting nut 502 is threadedly connected to the outside of the threaded rod 405.

[0032] In use, loosen the two bolts 406 to move the two rubber blocks 403 into the corresponding storage slots 402, releasing the restriction on the steel ball 404. Then pull the threaded rod 405 to make the steel ball 404 rotate inside the limiting groove 401 to adjust the angle between the threaded rod 405 and the ground until one end of the threaded rod 405 is aligned with the tree trunk. Then tighten the two bolts 406 to limit the steel ball 404 with the two rubber blocks 403. At this time, rotating the adjusting nut 502 on the outside of the threaded rod 405 can push the adjusting sleeve 5 and the top block 501 onto the tree trunk or branches to support the tree trunk.

[0033] Among them, a limiting ring 602 is fixedly connected to the outer side of the limiting rod 604, and a pull plate 603 is fixedly connected to the top of the limiting rod 604. Slide grooves b701 are opened on both sides of the inner wall of the slot 7. A limiting hole 703 is opened on the outer side of the rod 702. A limiting top block 704 is fixedly connected to one end of the rod 702. The slider 705 is slidably connected to the slide groove b701, and the limiting rod 604 passes through the limiting rod 604. A pull piece a8 is provided on one side of the base plate 1, and a pull piece b9 is provided on one side of the pull piece a8. Two sleeves 802 are fixedly connected to one side of the pull piece a8.

A rotating shaft limiting piece 902 is fixedly connected to both ends of the rotating shaft 901, and the outer side of the rotating shaft 901 is fixedly connected to the pull piece b9.

[0034] When support is needed around the tree trunk, remove multiple fixing devices, align the limiting slot 801 on the pull tab a8 with the slot 7 on one side of the support plate 2, remove the insert rod 702, pass the insert rod 702 through the limiting slot 801 on the pull tab a8, and align the two sliders 705 on the outside of the insert rod 702 with the two sliding grooves b701 on the inner wall of the slot 7. At the same time, pull the pull plate 603, causing the limiting ring 602 to compress the spring 601, which in turn moves the limiting insert rod 604 upward. Then, push the insert rod 702 into the interior of the slot 7 until one side of the limiting top block 704 contacts one side of the pull tab a8. At this point, release the pull plate 603, the spring 601 is released, and the limiting ring 602 and the limiting... The insertion rod 604 is reset, allowing the limiting insertion rod 604 to be inserted into the limiting hole 703, thereby fixing the insertion rod 702. The insertion rod 702 and the limiting top block 704 fix the pull piece a8 to one side of the support plate 2. Then, the pull piece b9 on one side of the pull piece a8 mounted on the support plate 2 is moved to the side of another fixing device, and the limiting groove 801 on the pull piece b9 is aligned with the slot 7 on the other fixing device. Then, another insertion rod 702 is passed through the limiting groove 801 on one side of the pull piece b9 and inserted into the slot 7 on the other support plate 2. The insertion rod 702 is then fixed by the limiting insertion rod 604. In this way, the splicing of two or more fixing devices can be achieved.

[0035] Among them, a limiting groove 302 is provided on one side of the telescopic groove 301, and a limiting slider 303 is slidably connected inside the limiting groove 302. A sliding groove a304 is provided on one side of the inner wall of the telescopic groove 301, and a push block 305 is fixedly connected to one side of the limiting slider 303. One side of the push block 305 is fixedly connected to the pin 306, and one end of the push block 305 passes through the sliding groove a304.

[0036] In use, take out the base plate 1 and support plate 2, move the base plate 1 and support plate 2 to the vicinity of the tree trunk, insert the ground nail 101 into the ground, then rotate the diagonal brace 3 to make the connector 203 rotate around the limiting block 202, then push the push block 305 to push the nail 306 from inside the telescopic groove 301 and insert it diagonally into the ground until the limiting slider 303 slides to the other end of the limiting groove 302 to fix the base plate 1 and support plate 2.

[0037] The working principle is as follows: In use, take out the base plate 1 and support plate 2, move the base plate 1 and support plate 2 to the vicinity of the tree trunk, insert the ground nail 101 into the ground, then rotate the diagonal brace 3 to make the connector 203 rotate around the limiting block 202, then push the push block 305 to push the nail 306 from inside the telescopic groove 301 and insert it diagonally into the ground until the limiting slider 303 slides to the other end of the limiting groove 302 to fix the base plate 1 and support plate 2.

[0038] Furthermore, loosen the two bolts 406 to move the two rubber blocks 403 into the corresponding storage slots 402, releasing the restriction on the steel ball 404. Then pull the threaded rod 405 to make the steel ball 404 rotate inside the limiting groove 401 to adjust the angle between the threaded rod 405 and the ground until one end of the threaded rod 405 is aligned with the tree trunk. Then tighten the two bolts 406 to restrict the steel ball 404 with the two rubber blocks 403. At this time, rotate the adjusting nut 502 on the outside of the threaded rod 405 to push the adjusting sleeve 5 and the top block 501 onto the tree trunk or branches to support the tree trunk.

[0039] When support is needed around the tree trunk, remove multiple fixing devices, align the limiting slot 801 on the pull tab a8 with the slot 7 on one side of the support plate 2, remove the insert rod 702, pass the insert rod 702 through the limiting slot 801 on the pull tab a8, and align the two sliders 705 on the outside of the insert rod 702 with the two sliding grooves b701 on the inner wall of the slot 7. At the same time, pull the pull plate 603, causing the limiting ring 602 to compress the spring 601, which in turn moves the limiting insert rod 604 upward. Then, push the insert rod 702 into the interior of the slot 7 until one side of the limiting top block 704 contacts one side of the pull tab a8. At this point, release the pull plate 603, the spring 601 is released, and the limiting ring 602 and the limiting... The insertion rod 604 is reset, allowing the limiting insertion rod 604 to be inserted into the limiting hole 703, thereby fixing the insertion rod 702. The insertion rod 702 and the limiting top block 704 fix the pull piece a8 to one side of the support plate 2. Then, the pull piece b9 on one side of the pull piece a8 mounted on the support plate 2 is moved to the side of another fixing device, and the limiting groove 801 on the pull piece b9 is aligned with the slot 7 on the other fixing device. Then, another insertion rod 702 is passed through the limiting groove 801 on one side of the pull piece b9 and inserted into the slot 7 on the other support plate 2. The insertion rod 702 is then fixed by the limiting insertion rod 604. In this way, the splicing of two or more fixing devices can be achieved.
