Description

Technical Field

[0001] The utility model relates to the field of municipal engineering, and particularly relates to an adjustable combined eccentric tree pit cover plate. Background Art

[0002] A tree pit cover plate, also known as a tree pit grate or tree hole grate, is a cover plate for enclosing and protecting a tree hole, and is also a landscape design that cannot be ignored in urban construction. There are various types of tree pit cover plates, with a designable appearance, materials including concrete, ductile iron, and composite materials, and shapes including square, circular, and irregular. The functions of the tree pit cover plate are as follows:

[0003] ① Protect trees: Using a tree pit cover plate can prevent other foreign objects from damaging the roots of trees and can well protect the growth of saplings.

[0004] ② Purify the street: Installing the tree pit cover plate at the root of the tree can not only protect the tree from damage, but also prevent the soil at the root of the tree from polluting the surrounding environment due to dust and rain.

[0005] ③ Beautify the environment: The tree pit cover plate can be made into various different colors and styles according to needs, which helps to beautify the street environment.

[0006] Currently, the tree holes of conventional tree pit cover plates are all located at the center of the tree pit cover plate. During actual installation and maintenance, as the trees grow, problems such as the tree trunk not being centered in the tree pit and the tree trunk shifting often occur, resulting in the situation that the tree pit cover plate does not match the tree pit from time to time. It is necessary to customize or cut the tree pit cover plate separately. This not only increases the cost but also affects the aesthetic effect.

[0007] There is also a case where the hole in the middle of the tree pit cover plate is processed much larger than the diameter of the tree trunk. Although the problem of the tree trunk not being centered is solved, since the area around the tree trunk cannot be effectively covered, the exposed part cannot play a good role in protecting the tree. Content of the Utility Model

[0008] In view of the above problems, the utility model provides an adjustable combined eccentric tree pit cover plate. By setting an embedded plate with an eccentric through hole rotatably connected to the cover plate frame, the angle can be rotated according to the position of the tree trunk in the tree pit to match the tree trunk. It is made modularly, with convenient construction, fast and efficient, and can cover the area around the tree trunk to the greatest extent.

[0009] An adjustable combined eccentric tree pit cover plate includes a cover plate frame. First eccentric through holes are provided on the upper and lower end faces of the cover plate frame. An embedded plate is rotatably connected to the side wall of the first eccentric through hole. Second eccentric through holes for accommodating the tree trunk are provided on the upper and lower end faces of the embedded plate.

[0010] Preferably, both the cover plate frame and the embedded plate are composed of two symmetrically structured pieces spliced together.

[0011] Preferably, the embedded plate is composed of two semi-circular pieces with eccentric through-holes spliced together.

[0012] Preferably, the cover plate frame is composed of two rectangular parallelepiped pieces with eccentric through-holes spliced together.

[0013] Preferably, a horizontally arranged U-shaped groove is provided on the side wall of the first eccentric through-hole.

[0014] Preferably, a raised block that cooperates with the U-shaped groove is provided on the outer side surface of the embedded plate.

[0015] Preferably, both the cover plate frame and the embedded plate are perforated plates.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] The present utility model is processed and manufactured according to the shape and size of the tree pit. During installation, it is composed of four parts. According to the specific position of the tree trunk in the tree pit, the angle of the cover plate frame and the embedded plate can be adjusted to accurately match, and its adaptability is more than 4.5 times higher than that of a conventional tree pit.

[0030] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0031] Aiming at the problems of the tree trunk not being centered in the tree pit and the tree trunk offsetting, etc., the present utility model discloses an adjustable combined eccentric tree pit cover plate. By designing two spliced eccentric circular embedded plates 2 inside the spliced cover plate frame 1 and rotating and adjusting the through-hole for accommodating the tree trunk, the perfect matching of the tree pit cover plate and the vertical rod is realized.

[0032] The cover plate frame 1 can be Figures 1 - 8 the square structure shown, or it can be Figure 9 the circular structure shown, which is determined according to the shape of the on-site tree pit. As Figure 10 shown, a first eccentric through-hole is processed inside the cover plate frame, a horizontal U-shaped groove 1-1 is processed on the inner side wall of the first eccentric through-hole, and a raised block 2-1 matching with the U-shaped groove 1-1 is processed on the outer side surface of the embedded plate 2. The raised block of the embedded plate can rotate in the horizontal plane along the U-shaped groove of the cover plate frame to adapt to the tree trunks at different positions. Both the cover plate frame 1 and the embedded plate 2 are made of ductile iron, and the areas other than the through-hole are processed into a hollow structure. On the one hand, it is beneficial to the circulation and infiltration of water and air, and on the other hand, it can improve the aesthetic effect.

[0033] As Figure 1As shown, when the tree pit is square, the first through hole is an eccentric hole near the left side of the cover plate frame, and the second through hole is an eccentric hole near the right side of the embedded plate, the initial position is the position where the tree trunk is located at the center of the entire tree pit. If the tree trunk is located at the upper left side of the tree pit, rotate the embedded plate counterclockwise by 90 degrees to reach the position as shown in Figure 2 , just surrounding the tree trunk. If the position of the tree trunk is in the left side of the tree pit, then on the basis of Figure 2 , continue to rotate the embedded plate by 90 degrees to reach the position as shown in Figure 3 . If the position of the tree trunk is at the lower left side of the tree pit, then on the basis of Figure 3 , continue to rotate the embedded plate by 90 degrees to reach the position as shown in Figure 4 , also just surrounding the tree trunk.

[0034] Similarly, several representative tree trunk positions as shown in Figures 5 - 8 can also be obtained by rotating the cover plate when initially laying the cover plate frame.

[0035] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
