Abstract
Description
Technical Field
[0001] This utility model relates to the field of green tree maintenance technology, and in particular to a tree pit grate. Background Technology
[0002] With urban development, trees are often planted along roads, squares, parks, and green belts to green and beautify cities. Planting pits are usually dug for easy planting. However, these pits cannot be completely filled after planting. To facilitate root respiration and subsequent maintenance, tree pit grates are often laid around the planting pits. A tree pit grate is generally a square board with a central hole, made up of four protective panels. Each panel has the same structure and is independent. Marble borders are laid around the tree pit grate. However, the growth of trees cannot be completely in the exact center of the tree pit.
[0003] Existing tree grate grates require on-site cutting of the inner hole to fit crooked tree roots, which is inconvenient to operate. Using and transporting whole tree grate grates is also inconvenient and affects their use. Meanwhile, spliced tree grate grates are not reliably fixed and are prone to being lost. Furthermore, as the trees grow, their roots protrude and arch, affecting the fixation of the tree grate grates. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] Reference Figure 1-3 A tree pit grate includes a tree pit cover plate 1 and an eccentric cover plate 2. Both the tree pit cover plate 1 and the eccentric cover plate 2 have connecting buckles 3 and limiting blocks 4 on their lower sides. The tree pit cover plate 1 and the eccentric cover plate 2 are each composed of multiple assembly blocks, facilitating manufacturing and transportation. A metal connecting frame 5, made of ductile metal, is provided under the connecting buckle 3 for easy deformation and fitting, fixing the connecting buckle 3 and facilitating subsequent repair and maintenance by construction personnel. The assembly blocks of the tree pit cover plate 1 and the eccentric cover plate 2 are connected by connecting buckles. 3 and metal connecting frame 5 are connected. The metal connecting frame 5 is set in a ring shape, which fits around the connecting buckle 3. The two ends overlap and are fixedly connected. The metal connecting frame 5 is adapted to the connecting buckle 3 and is bent and fitted to fix the connecting buckle 3, thereby fixing the connecting buckle 3 and reducing shaking. Both tree pit cover plate 1 and eccentric cover plate 2 are provided with through holes to facilitate irrigation and ventilation. Tree pit cover plate 1 and eccentric cover plate 2 are made of cast iron to improve strength and durability. The surface of tree pit cover plate 1 and eccentric cover plate 2 is coated with anti-rust paint to prevent the cover plate from rusting and polluting the environment.
[0022] Tree pit cover 1 includes trimmed cover 11 and filling cover 12. Eccentric cover 2 includes outer eccentric plate 21 and inner eccentric plate 22. The inner ring of filling cover 12 is fitted with the outer ring of outer eccentric plate 21, and the inner ring of outer eccentric plate 21 is fitted with the outer ring of inner eccentric plate 22. The outer and inner rings of outer eccentric plate 21 and inner eccentric plate 22 are eccentrically set. The eccentricity is adjusted to change the position of the inner hole of inner eccentric plate 22 to adapt to the position of tree root tilt.
[0023] The metal connecting frame 5 has a self-locking nail 6 on its lower side, and an anti-theft post 8 on its lower side. The self-locking nail 6 is connected to the anti-theft post 8. The anti-theft post 8 has an installation hole 7 on its upper side. The installation hole 7 is adapted to the self-locking nail 6. The installation hole 7 has a ratchet 71 inside. The self-locking nail 6 has a conical ring 61 adapted to the ratchet 71. The self-locking nail 6 is inserted into the installation hole 7, and the self-locking connection is completed through the ratchet 71 and the conical ring 61.
[0024] The anti-theft post 8 has a locking plate 9 on its lower side. The locking plate 9 has an arc-shaped cross-section and an enlarged edge at the top. The anti-theft post 8 has a clearance groove that matches the locking plate 9. There are multiple sets of locking plates 9, which are symmetrically arranged on both sides of the clearance groove. The bottom of the locking plate 9 is hinged to the anti-theft post 8. The bottom of the locking plate 9 is provided with a limiting structure. The locking plate 9 can be unfolded at a certain angle to facilitate fixing the anti-theft post 8.
[0025] In this embodiment, the construction workers bury anti-theft posts 8 in the tree pit and fix them with locking plates 9. If necessary, concrete can be added to improve the fixing strength. Then, the self-locking nails 6 are inserted into the installation holes 7 to install the tree pit cover plate 1 and the eccentric cover plate 2. First, the inner eccentric plate 22 close to the tree root is installed, and then the outer cover plate is installed in this way. With the help of the limiting block 4, the outer cover plate presses against the inner cover plate to ensure that the cover plate is flat and improve the connection strength.
[0026] The ratchet 71 and the conical ring 61 work together to ensure that the self-locking nail 6 is securely fixed. Adjust the fixed position of the tree pit cover 1 and the eccentric cover 2. After that, the green trees grow normally, the roots grow larger, and they lift up the cover. The metal connecting frame 5 deforms under the force, and the tree pit cover 1 and the eccentric cover 2 are opened. However, because of the connection of the metal connecting frame 5, it is ensured that the tree pit cover 1 and the eccentric cover 2 will not become loose, which improves reliability and safety, achieves anti-theft, avoids the loss of the cover, and reduces maintenance costs.
