Description

Technical Field

[0001] This utility model relates to the field of tree trunk support technology, specifically a tree support device. Background Technology

[0002] In the process of urban greening and landscaping construction, it is often necessary to transplant trees. However, the survival rate of some seedlings used for landscaping is low. Therefore, experimental cultivation is required first. After they have grown for a certain period of time and the survival rate has improved, they can be transplanted for urban greening projects. Because the root system of tree seedlings is underdeveloped, transplanted tree seedlings are prone to tilting and falling over during their growth, resulting in a reduced survival rate. To prevent trees from falling over, tree supports are commonly used to support and protect the tree seedlings.

[0003] Existing tree supports typically consist of three support rods, connecting and fixing components, and a trunk clamping structure. During installation, the top of the support rod is first fixed to the trunk using the trunk clamping structure, and then the bottom of the support rod is anchored into the soil using ground nails or conical stakes. While this fixing method is simple to operate, it has significant drawbacks in certain scenarios: when street trees are planted in tree pits (planting pits) next to sidewalks, the trunk clamping structure needs to be fixed at a certain height on the trunk (generally 2-3 meters). To ensure support stability, a horizontal distance of 1-2 meters needs to be maintained between the bottom of the support rod and the trunk. However, due to the common size of tree pits (≤1.5m × 1.5m), the end of the support rod easily extends beyond the tree pit boundary and falls directly onto the paved surface. In this case, traditional ground nails or stakes cannot penetrate the paved layer to form an effective anchor with the soil, resulting in a lack of foundation support at the bottom of the support rod, thus weakening the stability and reliability of the entire support system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tree support device that avoids the inability to secure the tree when the bottom of the support pole is on a hardened road surface.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tree support device, comprising a trunk clamping assembly and a support rod, wherein a placement groove is provided at the lower end of the support rod, and sliders are slidably connected to both sides inside the placement groove, and a sliding sleeve is provided between the two sliders and rotatably connected thereto, and a rotation groove is provided on the opposite surfaces of the two sliders, and a rotating shaft matching the rotation groove is fixedly connected to both sides of the sliding sleeve, and an insert rod is slidably connected to the middle position of the sliding sleeve.

[0006] Furthermore, positioning grooves are provided on both sides of the lower end of the support rod, and the positioning grooves are connected to the placement grooves. A positioning block matching the positioning groove is fixed to the side of the slider away from the sliding sleeve.

[0007] Furthermore, a pressing plate is fixed to the top of the insertion rod, the lower end of the insertion rod is conical, and the pressing plate is T-shaped.

[0008] Furthermore, the upper end of the support rod is provided with a hook block, and the two ends of the hook block are respectively fixed to the inner walls of the two sides of the placement groove. The upper end of the insertion rod is provided with a storage groove, and the upper end of the storage groove is slidably connected to a slide rod. The top of the slide rod is fixedly connected to a connecting plate, and a locking block is fixedly connected to the side of the connecting plate near the hook block. A limit block is fixedly connected to the middle position of the insertion rod.

[0009] Furthermore, an anti-detachment plate is fixedly connected to the bottom of the slide bar. The anti-detachment plate is circular, and its diameter is larger than the diameter of the upper outlet of the storage groove.

[0010] Furthermore, an elastic element is sleeved on the outside of the slide rod. The upper end of the elastic element is fixedly connected to the top of the storage groove, and the lower end of the elastic element is fixedly connected to the anti-detachment plate. The inner diameter of the elastic element is larger than the diameter of the upper outlet of the storage groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This tree support device, when supporting the tree trunk, only requires first leaning the trunk clamping component against the trunk, then fixing the trunk clamping component to the trunk with bolts, then moving the sliding sleeve and the insertion rod to make the insertion rod vertical, then pushing the sliding sleeve and the insertion rod to slide along the direction of the slider until the insertion rod is above the soil, then pressing the insertion rod to insert it into the soil, thereby fixing the support rod. The above structure can avoid the problem of the support rod not being able to be fixed when the bottom of the support rod is on a hardened surface, thus improving the stability and reliability of the entire support device.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-5 A tree support device includes a trunk clamping assembly 1 and a support rod 2. The lower end of the support rod 2 is provided with a placement groove 4. Slider 7 is slidably connected to both sides inside the placement groove 4. A sliding sleeve 6 is provided between the two sliders 7 and rotatably connected thereto. Rotation grooves are provided on the opposite surfaces of the two sliders 7. Rotating shafts matching the rotation grooves are fixed to both sides of the sliding sleeve 6. An insert rod 9 is slidably connected to the middle position of the sliding sleeve 6.

[0021] In this utility model, the tree support device only requires the trunk clamping component 1 to be leaned against the trunk first. Then, a bolt is passed through the trunk clamping component 1 and fixed to the trunk with the bolt. At this time, the bottom of the support rod 2 will be against the hardened road surface. Then, the sliding sleeve 6 and the insertion rod 9 are moved to make the insertion rod 9 vertical. Then, the sliding sleeve 6 and the insertion rod 9 are pushed to slide along the direction of the slider 7 until the insertion rod 9 is above the soil. Then, the insertion rod 9 is pressed to insert it into the soil. In this way, the support rod 2 can be fixed by the insertion rod 9. The above structure can avoid the problem of the support rod 2 not being able to be fixed because the bottom of the support rod 2 is on the hardened road surface, thus improving the stability and reliability of the entire support device. In addition, since the trunk clamping component 1 and the support rod 2 in this utility model are existing mature products, they will not be described in detail here.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, positioning grooves 3 are provided on both sides of the lower end of the support rod 2. The positioning grooves 3 are connected to the placement groove 4. The side of the slider 7 away from the sliding sleeve 6 is fixed with a positioning block 8 that matches the positioning groove 3.

[0023] Specifically, the positioning block 8 restricts the slider 7, making the slider 7 more stable when sliding.

[0024] like Figure 1 , Figure 2 and Figure 4As shown, a pressing plate 10 is fixed to the top of the insertion rod 9, the lower end of the insertion rod 9 is conical, and the pressing plate 10 is T-shaped.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the upper end of the support rod 2 is provided with a hook block 5, and the two ends of the hook block 5 are respectively fixed to the inner walls of the two sides of the placement groove 4. The upper end of the insertion rod 9 is provided with a storage groove 11, and the upper end of the storage groove 11 is slidably connected to a slide rod 14. The top of the slide rod 14 is fixedly connected to a connecting plate 15, and a locking block 16 is fixedly connected to the side of the connecting plate 15 near the hook block 5. A limiting block 17 is fixedly connected to the middle position of the insertion rod 9.

[0026] Specifically, during the entire storage process of the support device, the insertion rod 9 can be pulled upwards until the limiting block 17 abuts against the sliding sleeve 6. Then, the sliding sleeve 6 and the insertion rod 9 can be pushed until the positioning blocks 8 on both sides of the sliding sleeve 6 abut against the upper end of the positioning groove 3. Subsequently, the locking block 16 can be pushed to expose the connecting plate 15, and the connecting plate 15 can be pulled to move away from the insertion rod 9. Then, the insertion rod 9 can be rotated to overlap with the support rod 2. After the insertion rod 9 overlaps with the support rod 2, the connecting plate 15 can be pushed towards the hook block 5 to insert the locking block 16 into the hook block 5. In this way, the insertion rod 9 can be fixed on the support rod 2. Figure 1 As shown, the T-shaped pressing plate 10 can also serve as a restraint, making it easier for the locking block 16 to align with the hook block 5.

[0027] like Figure 4 As shown, an anti-detachment plate 12 is fixedly attached to the bottom of the slide bar 14. The anti-detachment plate 12 can restrict the slide bar 14 and prevent the slide bar 14 from detaching from the insertion rod 9. The anti-detachment plate 12 is circular, and the diameter of the anti-detachment plate 12 is larger than the diameter of the upper outlet of the storage groove 11.

[0028] like Figure 4 As shown, an elastic element 13 is sleeved on the outside of the slide bar 14. The upper end of the elastic element 13 is fixedly connected to the top of the storage groove 11, and the lower end of the elastic element 13 is fixedly connected to the anti-detachment plate 12. The inner diameter of the elastic element 13 is larger than the diameter of the upper outlet of the storage groove 11.

[0029] Specifically, the anti-detachment plate 12 can be pushed by the elastic element 13 to prevent the locking block 16 fixed on the connecting plate 15 from detaching from the hook block 5. In addition, it is worth noting that the elastic element 13 is preferably made of stainless steel or piano wire, which has a high fatigue limit and is suitable for long-term exercise. Its surface is nickel-plated or coated to have strong corrosion resistance. The elastic force range of the elastic element 13 is about 5N-10N, and the specific elastic force value should be changed according to the needs of actual application. This elastic force range is to avoid the occurrence of elastic failure.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
