Description

Technical Field

[0001] This utility model relates to the field of garden landscape decoration, specifically to a non-circular splicing tree pit cover device based on nested locking pins. Background Technology

[0002] With the rapid advancement of urbanization, the public green space of cities suffers from inconsistencies between the old and new eras, and urgently needs to be updated and beautified.

[0003] The existing methods of covering the bottom space of tree pits are mostly traditional vegetation cover and grass brick cover. Both of these methods have disadvantages such as long maintenance cycle of green plants and large number of personnel required. They are also easily damaged and cause a waste of human resources.

[0004] CN213978425U discloses a luminous tree pit cover, the main body of which is composed of two or four symmetrically spliced ​​panels. The main body has a hollow center, the hollowed-out portion being any of the circular, square, or angular shapes, used to encircle tree trunks. This tree pit cover has the following disadvantages: 1. The seams have large gaps, and splicing relies on visual inspection, easily resulting in inconsistent gap sizes and inaccurate alignment. 2. There is no dedicated positioning structure; it mainly relies on reinforcing ribs on the back of the main body to increase friction, making it prone to displacement. 3. The shape is relatively ordinary, and the symmetrical structure lacks novelty. Utility Model Content

The device also includes at least two protruding nested hole pin bases and multiple ball-head pins. The bottom of the body is provided with a groove corresponding to the shape of the protruding nested hole pin base for embedding. The groove is located at the junction of the first splicing plate and the second splicing plate, with a portion located on the first splicing plate and a portion located on the second splicing plate. Both the first splicing plate and the protruding nested hole pin base are provided with through holes for ball-head pins to pass through, and both the second splicing plate and the protruding nested hole pin base are provided with through holes for another ball-head pin to pass through.

[0008] As a preferred embodiment, the protruding nested hole pin base includes a flat plate portion and two protruding portions located on the upper end face of the flat plate portion, with a through hole penetrating through the protruding portions and the flat plate portion; the groove includes a primary groove that mates with the flat plate portion and two secondary grooves that mate with the protruding portions, with the through hole penetrating through the body and connecting the secondary grooves.

[0009] As a preferred embodiment, the flat portion is rectangular and the protruding portion is cylindrical.

[0010] As a preferred embodiment, the upper end of the ball-head pin is spherical with a diameter larger than the diameter of the through hole on the body; the lower end of the ball-head pin is rod-shaped.

[0011] As a preferred option, after the ball-head pin is inserted, its lower end extends 10cm below the base of the protruding nested hole pin.

[0012] As a preferred embodiment, the outer perimeter of the main body is square, and the joint between the first and second splicing plates is located at the center line of the square; both the first and second splicing plates include first and second irregularly shaped plates that are spliced ​​together. After the main body is assembled, the two first irregularly shaped plates are arranged diagonally, and the two second irregularly shaped plates are arranged diagonally; the number of protruding nested hole pin bases is four, with two protruding nested hole pin bases set between the first irregularly shaped plates of the first splicing plate and the second irregularly shaped plates of the second splicing plate, and two protruding nested hole pin bases set between the second irregularly shaped plates of the first splicing plate and the first irregularly shaped plates of the second splicing plate; the number of ball-head pins is eight.

[0013] As a preferred embodiment, the first irregularly shaped panel includes two right-angled sides, one joining side, and one first arc-shaped side; the second irregularly shaped panel includes two right-angled sides, one joining side, one second arc-shaped side, and one third arc-shaped side; the front section of the first arc-shaped side and the second arc-shaped side form a hollowed-out part surrounding the tree, and the rear section of the first arc-shaped side is joined with the third arc-shaped side.

[0014] As a preferred option, the hollowed-out part is leaf-shaped.

[0015] As a preferred option, both the first and second irregularly shaped plates are flat plates.

[0016] As a preferred option, both the first and second splicing plates are provided with bird-shaped drainage holes.

[0017] The principle of this utility model is:

[0018] Level the planting soil surface in the tree pit, and embed the protruding nested hole pin bases into the planting soil in a straight line according to the design position. Simply align the grooves of the first and second splicing plates with the protrusions of the protruding nested hole pin bases to automatically align them. Insert the ball head pin to lock and achieve a fixed connection. At the same time, the ball head pin is inserted into the soil to prevent the device from slipping.

[0019] This utility model has the following advantages:

[0020] 1. The automatic splicing and alignment of the main body is achieved through the cooperation of the protruding nested hole pin base and the groove, which can quickly and accurately position and reduce splicing errors.

[0021] 2. The ball-head pins allow for quick fixation, achieving rapid installation. The ball-head pins also penetrate deep into the soil to prevent slippage of the device.

[0022] 3. Two types of irregularly shaped cover plates are adopted, namely, the first splicing plate and the second splicing plate both include the first irregularly shaped plate and the second irregularly shaped plate, which takes into account the aesthetics of the landscape while facilitating production and relocation.

[0023] 4. The drainage holes serve both a drainage and decorative purpose, making them both practical and aesthetically pleasing.

[0024] 5. The modular installation structure enables rapid positioning, installation, and disassembly of the tree pit cover. Attached Figure Description
