Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal greening, in particular to a tree supporting device which is easily disassembled and utilized. Background Art
[0002] In municipal greening and landscaping, newly planted trees, especially those with fragile structures, require artificial support using tree supports to prevent or reduce damage from external factors such as weather and human intervention. Conventional tree supports typically consist of two paired support units, each of which includes a support rod with a semi-hoop at the upper end. The two semi-hoops are bolted together to encircle the tree's trunk. The lower end of the support rod is provided with a footing, which is perforated and fixed to the soil with a screw.
[0003] Although the above-mentioned tree support device is easy to install and implement, and can provide stable support for trees to avoid structural damage, it is difficult to remove the tree support device when the roots of newly planted trees gradually grow and their own stability meets the needs of independent support, or when it is necessary to remove the tree support device for reasons such as aesthetics and reuse. That is, the drill nails are often difficult to pull out because the soil is repeatedly exposed to rainfall and evaporation, which makes the surface soil compacted, or the roots of trees and grass are entangled and there is a lack of fulcrums, which consumes a lot of manpower. Utility Model Content
[0004] The utility model aims to provide a tree supporting device which is easy to disassemble and reuse, and is convenient to disassemble and reuse under the condition that the tree supporting device is stably and tightly combined with the ground.
[0005] In order to solve the above technical problems, the specific solution adopted by the present invention is: a tree support device that is easy to disassemble and use, including multiple support rods, the upper ends of the support rods are provided with support mechanisms for supporting tree branches, the lower ends of the support rods are provided with feet connected to the ground, all the feet are provided with through holes and fixed to the ground by nails, the upper ends of the nails are provided with hexagonal screw heads, the lower edges of the hexagonal screw heads are provided with first wedge blocks, and the upper edges of the feet are provided with second wedge blocks, the wedge surfaces of the first wedge blocks and the second wedge blocks can overlap as the nails are nailed into the ground, and the second wedge blocks can push up the overall structure consisting of the first wedge block, the hexagonal screw head and the nails during the rotation of the hexagonal screw heads.
[0006] Preferably, the number of the first wedge blocks and the number of the second wedge blocks are both multiple and corresponding.
[0007] Preferably, the plurality of first wedge-shaped blocks are evenly spaced apart along the circumference of the hexagonal screw head, and the plurality of second wedge-shaped blocks are evenly spaced apart along the circumference of the through hole.
[0008] Preferably, the first wedge blocks are grouped in pairs and form a V-shaped lower protrusion at the lower edge of the hexagonal screw head, and the second wedge blocks are grouped in pairs and form a V-shaped upper groove at the upper edge of the foot, and the upper groove can be fitted with the lower protrusion.
[0009] Preferably, the vertical projections of the first wedge-shaped block and the second wedge-shaped block are both arc-shaped.
[0010] Preferably, the first wedge-shaped block and the drill nail are integrally formed, the inner side of the first wedge-shaped block is integrally connected to the outer side of the drill nail, and the first wedge-shaped block and the drill nail are both welded and fixed to the hexagonal screw head.
[0011] Preferably, the second wedge-shaped block is welded and fixed on the base, and the inner side of the second wedge-shaped block is in close contact with the outer edge of the perforation.
[0012] Preferably, the angles between the wedge surfaces of the first wedge-shaped block and the second wedge-shaped block and the horizontal plane are both 15-30 degrees, and the heights of the first wedge-shaped block and the second wedge-shaped block are both 0.5-1 cm.
[0013] The anchor and nail of the present invention differ significantly from existing tree support devices. Specifically, a hexagonal screw head is provided at the top of the nail, and a first wedge is provided at the bottom edge of the hexagonal screw head. A second wedge is provided at the top edge of the anchor. After the nail is driven into the ground by striking the hexagonal screw head with a hammer, the wedge surfaces of the first and second wedges intersect. During disassembly, simply turning the hexagonal screw head with a tool such as a wrench increases torque by increasing the length of the wrench's handle, making the nail rotate more easily. Simultaneously, the wedge surface of the second wedge lifts the first wedge and the nail connected to it.
[0014] Therefore, when the hexagonal screw head is rotated, the drill nail rotates and rises at the same time, and the soil wrapped around the drill nail becomes loose as a whole, which is conducive to applying a smaller force to pull out the drill nail; on the other hand, after the hexagonal screw head rotates and rises, a certain gap is generated between its lower edge and the ground foot, thereby forming a fulcrum and allowing tools such as a crowbar to be inserted, making it easier to completely pull out the drill nail.

[0020] The technical solution of the present invention is described below through two embodiments:
[0021] Example 1
[0022] like Figure 1 As shown, the tree support device of this embodiment that is easy to disassemble and utilize is the same as the conventional tree support in the prior art in that it includes multiple support rods 5, and the upper ends of the support rods 5 are fixed with the following Figure 4 The cup 1 shown has a first through-hole 3 provided in the longitudinal direction for the upper end of the support rod 5 to be sleeved and fixed; the cup 1 also has a second through-hole 4 provided in the transverse direction for the cable tie 2 to pass through. The cable tie 2 passes through the second through-hole 4 on the cup 1 at the top of all the support rods 5 to enclose the tree branches to form a support mechanism for supporting the tree branches. It should be noted that in order to adapt to the continuous growth of the tree branches, a certain gap can be reserved between the cable tie 2 and the tree branches. After the tree branches grow thicker and press the cable tie from the inside and outside, the cable tie 2 can be cut and removed, and then a new cable tie 2 can be inserted to adapt to the continuous growth of the tree branches. Or after the tree roots gradually grow and their own stability meets the needs of independent support, the support rod 5 and the support mechanism can be removed as a whole by utilizing the easy-to-disassemble feature of the present invention. The above adjustment method is a conventional technical means in this field and will not be described in detail here.
[0023] The lower end of the support rod 5 is provided with a foot 6 made of a rectangular steel plate. The foot 6 is provided with a through-hole (not shown in the figure). The drill nail 8 is passed through the through-hole and the upper end of the drill nail 8 is hit by a hammer to drive the drill nail 8 into the ground soil, and the foot 6 is fixed to the ground to provide stable support. Unlike conventional tree support devices, the upper end of the drill nail 8 in this embodiment is provided with a hexagonal screw head 7, so that the drill nail 8 can be turned with the aid of a wrench to loosen the soil wrapped around the outer periphery of the drill nail 8. The lower edge of the hexagonal screw head 7 is provided with two symmetrically distributed first wedge blocks 9 in the front and back. The first wedge blocks 9 are arc-shaped and distributed along the circumference of the upper end of the drill nail 8. The first wedge blocks 9 and the drill nail 8 are integrally formed, so that the inner side of the first wedge block 9 is integrally connected to the outer periphery of the drill nail 8, thereby improving the stability of the structure. Two second wedges 10 are welded to the upper edge of the foot 6, located outside the perforation. The wedge surfaces of the second wedges 10 have the same inclination angle as the first wedges 9, both at 20°, and are 0.5 cm high. After the hexagonal screw 7 is hammered through the perforation, driving the drill nail 8 into the opposite side, the wedge surfaces of the first and second wedges intersect.
[0024] During the disassembly process of this embodiment, the hexagonal nut 7 is screwed with a wrench to rotate the first wedge block 9 relative to the second wedge block 10. After the wedge surfaces of the two are in contact, the drill nail 8 is lifted by the wedge surface of the second wedge block 10, which can drive the drill nail 8 to rotate and move upward synchronously, thereby loosening the soil wrapped around the outer periphery of the drill nail 8, and creating a certain distance between the drill nail 8 and the foundation 6 after the drill nail 8 rises, and then the crowbar can be inserted using this distance, and the drill nail 8 can be pried out with the help of the crowbar.
[0025] Example 2
[0026] The main structure of this embodiment is the same as that of embodiment 1, except that: Figure 3 As shown, in this embodiment, two first wedge blocks 9 are respectively provided on the front and rear sides of the hexagonal screw head 7. The two first wedge blocks 9 on the same side are integrally formed and form a V-shaped lower protrusion. Correspondingly, two second wedge blocks 10 are respectively provided on the front and rear sides of the foot 6. The two first wedge blocks 9 on the same side are integrally formed and form a V-shaped upper groove. When hammering the hexagonal screw head 7 to insert the drill nail 8 into the ground, the lower protrusion can just fit into the upper groove. During the removal process, rotating the hexagonal screw head 7 clockwise or counterclockwise can drive the drill nail 8 to rotate and move upward through the wedge surface compression fit of the corresponding first wedge block 9 and second wedge block 10. Therefore, compared with Example 1, this embodiment can avoid the obstruction of unilateral obstacles that may exist around the foot 6, making it more applicable.
