Description

Technical Field

[0001] The utility model relates to the technical field of manhole cover frames, in particular to a manhole cover frame with adjustable size. Background Art

[0002] As an important part of urban infrastructure, manhole cover frames are widely used in various types of manholes, such as drainage wells, cable wells, etc. However, the traditional manhole cover frame design often has the problem of fixed size, that is, its size is mostly a single specification and can only be adapted to manholes of a specific diameter. Although this design method simplifies the production and installation process to a certain extent, it greatly limits the scope of application of manhole cover frames.

[0003] In actual applications, due to the differences in wellhead diameters, fixed-size manhole cover frames often cannot fully adapt to various wellheads. This results in the need to customize manhole cover frames of different sizes for wellheads of different diameters during installation, which increases production costs and installation difficulties;

[0004] In addition, with the continuous development of urban construction, the specifications of manhole diameters are constantly changing. Fixed-size manhole cover frames cannot adapt to such changes, resulting in the need to frequently replace manhole cover frames of different sizes when replacing or repairing the manhole, increasing maintenance costs and inconvenience.

[0005] Therefore, a manhole cover frame with adjustable size is needed to overcome the occurrence of the above problems. Utility Model Content

[0006] In order to solve the above problems, an embodiment of the utility model provides a manhole cover frame with adjustable size, which achieves the purpose of solving the problems raised in the background technology.

[0007] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a manhole cover frame with adjustable size, including a combination block one, a combination block two, and a corner block; both ends of the combination block one and one end of the combination block two are provided with a card block, and the other end of the combination block two and both ends of the corner block are provided with a card slot used in conjunction with the card block.

[0008] As a further improvement of the above technical solution:

[0009] The first and second assembly blocks are in a straight line shape, and the corner block is in an L shape.

[0010] The first assembly block, the second assembly block and the corner block are all provided with protrusions.

[0011] The bottoms of the first assembly block, the second assembly block and the corner block are all provided with grooves.

[0012] The beneficial effects of the embodiments of the utility model are:

[0013] In actual use, the manhole cover frame can be assembled by combining the combination block 1, the combination block 2 and the corner block. The number of the combination block 1 and the combination block 2 can be adjusted to achieve the purpose of adjusting the size of the manhole cover frame, that is, it can be adapted to different manhole openings for use;

[0014] When assembling the assembly block 1, the assembly block 2 and the corner block, since the assembly block 1 and the corner block are both symmetrical structures, there is no need to distinguish the directions of the assembly block 1 and the corner block, which facilitates assembly.

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0022] See also Figures 1 to 5 The embodiment of the utility model discloses a manhole cover frame with adjustable size, including a combination block 1, a combination block 2, and a corner block 3;

[0023] Both ends of the assembly block 1 and one end of the assembly block 2 are provided with a card block 4, and the other end of the assembly block 2 and both ends of the corner block 3 are provided with a card slot 5 used in conjunction with the card block 4;

[0024] In actual use, the manhole cover frame can be assembled by combining the combination block 1, the combination block 2, and the corner block 3. The number of the combination block 1 and the combination block 2 can be adjusted to achieve the purpose of adjusting the size of the manhole cover frame, so that it can be adapted to different manhole openings for use;

[0025] When assembling the assembly block 1, the assembly block 2 and the corner block 3, since the assembly block 1 and the corner block 3 are both symmetrical structures, there is no need to distinguish the directions of the assembly block 1 and the corner block 3, which facilitates assembly.

[0026] As a further illustration of this application:

[0027] The combination block 1 and the combination block 2 are in a straight line shape, and the corner block 3 is in an L shape. A square frame is formed by combining the combination block 1, the combination block 2, and the corner block 3. The side length of the square frame is adjusted by changing the number of the combination blocks 2, thereby achieving the purpose of adjusting the size of the square frame.

[0028] As a further illustration of this application:

[0029] Combination block 1, combination block 2, and corner block 3 are all provided with protrusions 6; the bottoms of combination block 1, combination block 2, and corner block 3 are all provided with grooves 7; the structural strength is enhanced by the protrusions 6, and at the same time, when the manhole cover frame is buried at the wellhead, it is necessary to cast the manhole cover frame with concrete, so as to increase the contact area through the protrusions 6 and the grooves 7 and improve the casting stability.

[0030] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.
