Description

Technical Field

[0001] This utility model relates to the field of municipal infrastructure, and in particular to a tree pit cover based on a mechanical aperture structure that can automatically adjust the opening size as the tree grows naturally. Background Technology

[0002] Tree pit covers are municipal facilities installed in public spaces such as urban roads and squares. They are mainly installed above tree pits to protect tree roots, prevent soil erosion, and improve the cleanliness of the surrounding environment. They play an important role in modern urban greening and public environment construction.

[0003] Most common tree pit covers currently used have a fixed size design. While they may meet the size requirements of trees initially, as trees grow and their trunk diameter increases, the fixed cover gradually becomes compressed between itself and the trunk. This not only restricts the tree's natural growth space, but also easily causes bark damage, trunk rot, and a high tree mortality rate. Furthermore, repeated replacements result in significant material waste. To address this issue, some tree pit covers have been improved, with assembly and splicing structures that facilitate adjustment to some extent. However, they still require periodic manual adjustment, replacement, or removal, increasing maintenance workload and costs.

[0004] Therefore, there is an urgent need to propose a tree pit cover design that is simple in structure, easy to install, and can automatically adapt and adjust the opening size according to the natural growth process of trees, so as to ensure the healthy growth of trees, reduce the frequency of later artificial intervention, and improve the service life and management efficiency of urban greening facilities. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an adaptive tree pit cover based on an aperture structure, which can automatically adjust the size of the central opening as the diameter of the tree increases, without the need for external power or manual adjustment. It has a simple structure, is easy to install, and can effectively protect the healthy growth of trees and reduce maintenance costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adaptive tree pit cover based on an aperture structure includes, from bottom to top, a base assembly, a blade assembly, and a top assembly. The base assembly is fixedly mounted on the ground, and the top assembly is detachably connected to both the base assembly and the blade assembly. The blade assembly and the top assembly rotate in tandem. The base assembly includes a first split base and a second split base, with multiple base rails on their surfaces to guide the sliding of the blades. The blade assembly consists of eight quadrilateral blades, each with multiple first protrusions at its bottom. The quadrilateral blades are embedded in the base rails via these protrusions, allowing them to slide within the base rails. This invention utilizes a split structure for both the base assembly and the top assembly, facilitating rapid installation around existing trees.

[0008] Furthermore, the first split base and the second split base are connected by a first connecting member, and the surfaces of the first split base and the second split base are also provided with a plurality of base component hooks.

[0009] Furthermore, the number of the first connecting components is even.

[0010] Furthermore, the front of the first split base and the second split base are provided with a plurality of first rainwater diversion holes.

[0011] Furthermore, the front side of the quadrilateral blade is provided with multiple blade slide rail grooves.

[0012] Furthermore, the front side of the quadrilateral blade is provided with multiple second rainwater guiding holes.

[0013] Furthermore, the top assembly includes a first split cover plate and a second split cover plate, which cover the base assembly and the blade assembly. The bottom of the first split cover plate and the second split cover plate is provided with a plurality of second protrusion structures, which are built into the blade slide rail groove so that the top assembly can be driven to rotate synchronously when the quadrilateral blade slides.

[0014] Furthermore, the bottom edges of the first and second split-type cover plates are provided with multiple top component edge sliding tracks, which are connected and cooperate with the hooks of the base component, so that the top component is installed on the base component.

[0015] Furthermore, the first split cover plate and the second split cover plate are connected and fixed by a second connecting member.

[0016] Furthermore, the number of the second connecting members is even.

[0017] Furthermore, the first and second split-type cover plates are provided with a third rainwater diversion hole on their front sides.

[0018] The purpose of the first, second, and third rainwater diversion holes in this invention is to ensure that rainwater can smoothly converge into the soil and infiltrate and drain away.

[0019] Furthermore, the base slide rail, blade slide rail groove, and top component edge slide rail are all concealed tracks to prevent soil and other debris from accumulating in the tracks and thus affecting the sliding of the blade assembly.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The adaptive tree pit cover based on an aperture structure of this invention includes a base assembly, a blade assembly, and a top assembly. The base assembly is fixed to the ground, and the top assembly is placed on the top layer. Both the base assembly and the top assembly adopt a split structure, which facilitates quick installation around existing trees. By employing an aperture structure, this invention relies solely on the radial thrust of the tree during its growth to drive the movement of the blade assembly, automatically expanding the opening size. This avoids the compression of the tree trunk caused by traditional fixed covers, ensuring the tree can grow freely without the need for external energy or human intervention.
