Description

Technical Field

[0001] This utility model belongs to the field of light pole technology, specifically relating to a light pole with a dovetail groove and a combined light pole. Background Technology

[0002] To increase the strength of light poles or create decorative lines, grooves, such as V-grooves or rectangular grooves, are sometimes machined into them along their axial direction. These grooves can be formed directly by stamping or bending. To reliably mount other functional components on the light pole, some light poles are designed with dovetail grooves that are generally aligned along their axial direction. Due to their shape limitations, dovetail grooves cannot be directly formed by stamping or bending. If dovetail grooves are to be machined on light poles with identical cross-sectional shapes and dimensions, they can be machined by drawing or by splicing, such as... Figure 2 As shown, four semi-finished products are first processed by bending, and then the four semi-finished products are assembled and welded into a lamp post. The lamp post has a dovetail groove, and the weld is located at the bottom of the dovetail groove. If the dovetail groove is processed on a tapered lamp post, it cannot be processed by drawing; currently, it can only be processed by rolling. For example, the scheme disclosed in patent CN115228987A, entitled "A Tapered Irregular Tube Forming Equipment and Forming Method," has the following production method: first, two semi-finished U-shaped parts are processed from sheet metal; the ends of the two wing plates on both sides of the U-shaped parts are bent; then, the two semi-finished U-shaped parts are assembled and welded into a lamp post. The weld of the dovetail groove formed by the splicing is located at the bottom of the dovetail groove. Figure 1 As shown.

[0003] The above two methods of processing light poles with dovetail grooves have the following drawbacks: due to the narrow opening and wide bottom of the dovetail groove, grinding tools such as grinding wheels cannot properly grind the weld seam, which affects the dimensional accuracy and uniformity of the dovetail groove, making installation inconvenient and affecting the overall aesthetics of the light pole. Summary of the Invention

[0004] To address the technical problem of insufficient forming precision in spliced ​​dovetail grooves, this utility model provides a light pole with dovetail grooves, which can avoid weld seams within the dovetail grooves, improve the overall aesthetics of the light pole, and avoid affecting the installation of the load.

[0005] To address the technical problem of insufficient forming precision in spliced ​​dovetail grooves, this utility model also provides a combined light pole that avoids weld seams within the dovetail groove, improving the overall aesthetics of the light pole and preventing interference with load installation.

[0006] The embodiments of this utility model are achieved through the following technical solutions:

[0007] A light pole with a dovetail groove is formed by combining at least two machined parts of the same length as the light pole, at least one of which has a dovetail groove. The machined parts are joined together and welded to form the light pole, and the weld seam is kept outside the concave part of the light pole's cross-section.

[0008] In one embodiment of the present invention, the lamp post includes a first processed part and a second processed part, both of which have two dovetail grooves and are bent between the two dovetail grooves. The first processed part and the second processed part are then welded together after bending.

[0009] In one embodiment of this utility model, the first processed part and the second processed part have the same structure.

[0010] In one embodiment of this utility model, the lamp post includes four processed parts, each of which has a dovetail groove, and the four processed parts are joined together to form the lamp post.

[0011] In one embodiment of this utility model, the four processed parts include two identical first processed parts and two identical second processed parts.

[0012] In one embodiment of this utility model, the lamp post is a tapered lamp post.

[0013] A modular light pole is formed by combining at least two light pole sections, at least one of which is the aforementioned light pole with a dovetail groove.

[0014] In one embodiment of this utility model, at least one section of the lamp post is a tapered lamp post.

[0015] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0016] This invention ensures that the weld seam of the light pole with dovetail groove is not located in the concave part of the light pole's cross-section, such as the concave part of the dovetail groove. This avoids the weld seam being inside the dovetail groove, facilitating subsequent processing such as weld seam grinding, improving the overall aesthetics of the light pole, and preventing it from affecting the installation load.

[0030] A light pole with a dovetail groove is formed by combining at least two machined parts of the same length as the light pole, at least one of which has a dovetail groove. The machined parts are joined together and welded together, and the weld seam is kept outside the concave part of the cross-section of the light pole.

[0031] The following embodiments are further elaborated based on the above solutions.

[0032] Please refer to Figure 3-6 This embodiment provides a light pole with a dovetail groove. The light pole is formed by combining at least two machined parts of the same length as the light pole. Among all the machined parts, at least one of the machined parts has a dovetail groove. After the machined parts are assembled, they are welded to form a light pole. Moreover, the weld between two adjacent machined parts is not in the concave part of the cross-section of the light pole, such as in the dovetail groove, to ensure that the weld is easy to grind. Compared with the light poles in the prior art where the weld is located in the dovetail groove, the light pole structure of this embodiment can improve the overall aesthetics of the light pole and does not affect the installation of load in the dovetail groove.

[0033] In this embodiment, the lamp post includes a first processed part 1 and a second processed part 2. Both the first processed part 1 and the second processed part 2 have two dovetail grooves, and both the first processed part 1 and the second processed part 2 are bent between the two dovetail grooves. The first processed part 1 and the second processed part 2 are then welded together after bending. Specifically, the first processed part 1 and the second processed part 2 have the same structure. Taking the first processed part 1 as an example, ... Figure 3As shown, to produce an octagonal light pole, the first processed part 1 includes a dovetail groove, wing plates, and a connecting plate. Two dovetail grooves are provided, each with a wing plate fixed to one side. Adjacent wing plates between the two dovetail grooves are connected by a connecting plate. Furthermore, a connecting plate is also connected to the wing plate on the free side of one of the dovetail grooves. The first processed part 1 is L-shaped overall. It should be noted that both the first processed part 1 and the second processed part 2 are processed from sheet metal using roll forming or bending methods. During the assembly and welding of the light pole, the first processed part 1 and the second processed part 2, which have identical structures, are first joined together to form a U-shape. Then, one wing plate of the first processed part 1 is welded to the connecting plate of the second processed part 2, and one wing plate of the second processed part 2 is welded to the connecting plate of the first processed part 1. Compared with existing technologies, the weld seam between the two processed parts is located on the outer edge, facilitating weld grinding, improving the overall aesthetics of the light pole, and preventing the weld seam within the dovetail groove from affecting the installation load.

[0034] It should be noted that, as Figure 4 As shown, when the light pole is a quadrilateral light pole, the structure of the first processed part 1 includes a dovetail groove and a wing plate. There are two dovetail grooves, each fixed to a wing plate on both sides. The two dovetail grooves are bent at a 90° angle, making the first processed part 1 L-shaped overall. A connecting plate is also connected to the wing plate on the free side of one of the dovetail grooves. During the assembly and welding of the light pole, the first processed part 1 and the second processed part 2, which have identical structures, are first joined together to form a U-shape. Then, the wing plate of the first processed part 1 is welded to the wing plate of the second processed part 2.

[0035] In this embodiment, the light pole can also be formed by welding four machined parts together, each part having a dovetail groove, and the four machined parts being joined together to form the light pole. For example... Figure 5 As shown, when the light pole is octagonal, the four processed parts include two identical first processed parts 1 and two identical second processed parts 2. The first processed part 1 has a dovetail groove, with wing plates on both sides of the dovetail groove, and connecting plates connected to the wing plates, forming an approximate W shape. The second processed part 2 also has a dovetail groove, with wing plates on both sides of the dovetail groove. Both the first processed parts 1 and the second processed part 2 are processed from sheet metal by roll forming or bending. During the assembly and welding of the light pole, the two identical first processed parts 1 and the two identical second processed parts 2 are joined together to form a U-shape. Adjacent processed parts are then welded, with the weld located on the outer edge, avoiding the weld being located inside the dovetail groove and facilitating weld grinding.

[0036] like Figure 6As shown, when the light pole is a quadrilateral light pole, all four processed parts adopt the same structure, that is, the processed part has a dovetail groove, and the two wings of the dovetail groove also have wing plates. When assembling and welding the light pole, the four identical processed parts are put together to form a square shape, and then the two adjacent processed parts are welded. The weld is located on the outer edge.

[0037] It should be noted that for the four types of light pole structures mentioned above, when the light pole is a constant diameter structure (i.e., the pipe diameter is consistent along the length direction), all processed parts are formed using rectangular plates. When the light pole is a tapered light pole (i.e., the pipe diameter gradually increases along the length direction), all processed parts are first processed from rectangular plates to create semi-finished products with dovetail grooves. Then, the wing plates of the semi-finished products are cut to make the overall outline of the semi-finished products an isosceles trapezoid. Finally, the wing plates are bent to form connecting plates. If there are no connecting plates, the wing plates are not bent after cutting.

[0038] This invention ensures that the weld seam of the light pole with dovetail groove is not located in the concave part of the light pole's cross-section, such as the concave part of the dovetail groove. This avoids the weld seam being inside the dovetail groove, facilitating subsequent processing such as weld seam grinding, improving the overall aesthetics of the light pole, and preventing it from affecting the installation load. Example

[0039] This embodiment provides a combined light pole, formed by combining at least two light pole sections. At least one light pole section is the dovetail-groove light pole of Embodiment 1, and at least one light pole section is a tapered light pole. For example, when the combined light pole has two sections, the lower light pole and the upper light pole are fixed together by bolts or welded together. The diameter of the lower light pole is larger than that of the upper light pole, and at least one of the lower and upper light pole sections is the tapered light pole described in Embodiment 1.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
