Description

Technical Field

[0001] The utility model relates to the technical field of power auxiliary equipment, in particular to a composite material street code. Background Art

[0002] From two-line street codes to multi-line street codes, usually the most common way to install low-voltage lines (low-voltage output side of the transformer) in rural areas is through cement poles, but it is inconvenient to plant cement poles on the streets in towns, so street codes came into being.

[0003] Existing mounting brackets for street stakes have poor corrosion resistance. Prolonged exposure to air can easily corrode the mounting bracket, causing the street stake to loosen, failing to meet existing user needs. Furthermore, during long-term use, street stake components can become loose or break due to the power supply circuit being in a floating state.

[0034] The embodiment of the utility model patent provides a composite material street code, which can effectively improve the corrosion resistance of the street code during use by arranging a composite layer 500 coating composed of a composite material on the base, the support rod 200 and the iron core 300. At the same time, this technical solution can improve the stability of the street code, avoiding the loosening of various components of the street code caused by the shaking of the wires during long-term use.

[0035] Specifically, such as Figure 1-3 As shown, a composite material street code provided by an embodiment of the utility model patent includes: a base 100, a support rod 200, an iron core 300, an insulator 400 and a composite layer 500 for coating, wherein the base 100 includes a main body 110, and the edges on both sides of the main body 110 are formed with side wings 120 extending along the width direction; there are multiple support rods 200, and the multiple support rods 200 are arranged side by side at equal intervals along the length direction of the main body 110, one end of which is connected to the main body 110, and the other end extends vertically away from the main body 110, and each support rod 200 is provided with a mounting hole 201, and the axes of the multiple mounting holes 201 are all located at the same position. On the same straight line parallel to the main body 110; penetrated into all the mounting holes 201, and anti-slip parts 310 are formed at both ends; the insulator 400 includes a plurality of, and at least is mounted on the portion of the iron core 300 located between two adjacent support rods 200; the composite layer 500 is coated on the surface of the base 100, the support rod 200 and the iron core 300, and the composite layer 500 includes a first protective layer 510 and a second protective layer 520 coated in sequence, the first protective layer 510 includes an anti-corrosion galvanized layer 511 and an anti-aging passivation layer 512, and the second protective layer 520 includes a phenolic resin nano-spray paint layer 521 and a polyethylene powder dipping layer 522. In this technical solution, an anti-corrosion galvanized layer 511, an anti-aging passivation layer 512, a phenolic resin nano-spray paint layer 521 and a polyethylene powder dipping insulation layer 522 are provided, which can improve the corrosion resistance, electrical insulation resistance, dustproof and waterproof properties of the support frame's "X"-shaped base and the separating support column itself, further improve the service life of the street code, and meet the service life of existing users.

[0036] Through the above-described technical solution, the surfaces of the base 100, support rod 200, and iron core 300 are coated with a composite layer 500, thereby providing corrosion protection for the main components of the street code, ensuring that it can withstand the erosion of the natural environment such as rain and sun when installed outdoors for a long time, thereby ensuring the service life of the street code. During the installation of the street code, the base 100 is fixed to a wall or pillar, and the support rod 200 is supported by the main body 110 to prevent direct contact between the support rod 200 and the wall or pillar, thereby preventing corrosion of the support rod 200. In addition, the side wings 120 provided on both sides of the base 100 provide a stabilizing effect, ensuring the stability of the base 100 after installation. In this embodiment, the insulation can be installed in multiple locations, such as where the iron core 300 is located between the two support pillars, or where the support rod 200 is located between the base 100 and the wall, thereby meeting the needs of various usage scenarios.

[0037] In this embodiment, a recessed portion 111 is provided on one side of the main body 110, so that the cross section of the base 100 is in the shape of a Chinese character "J". A number of equally spaced fixing holes 112 are evenly spaced along the length of the main body 110. During the installation of the street code, by setting the main body 110 in a Chinese character "J", the distance between the support rod 200 and the installation surface such as the wall can be further increased or decreased, reducing the contact between them. At the same time, in the process of shaking, the side walls on both sides of the main body 110 can absorb the shaking, thereby preventing the shaking from directly affecting the connection between the base 100 and the wall. During the installation process, fixing holes 112 are provided on the top surface of the main body 110. The fixing holes 112 are for the installation bolts to pass through. The main body 110 is locked to the wall by the installation bolts, thereby improving the installation stability of the base 100.

[0038] In this embodiment, to further enhance the secure installation of the street bracket, reinforcement holes 121 are spaced evenly along the length of the side wing 120. These reinforcement holes 121 are also provided for mounting bolts to pass through and connect to a mounting surface such as a wall. This allows the side wing 120 to be securely attached to the wall when tightened by the mounting bolts, ensuring the stability of the base 100.

[0039] In this embodiment, in order to improve the firmness of the connection between the base 100 and the support rod 200, a plurality of connection holes 113 corresponding to the support rods 200 are formed on the top surface of the main body 110 at equal intervals along its length. One end of the support rod 200 is inserted into the connection hole 113 and welded to the main body 110. In other words, the support rod 200 is inserted into the connection hole 113 in advance, and then the main body 110 and the support rod 200 are welded. At this time, since the support rod 200 is already in the connection hole 113, there is a mutual compressive force between the support rod 200 and the inner wall of the connection hole 113. Subsequently, welding can ensure the reliability and firmness of the connection between the support rod 200 and the main body 110.

[0040] In this embodiment, to further improve the reliability of the connection between the support rod 200 and the base 100, one end of the support rod 200 passing through the connection hole 113 extends toward the inner recess 111 to form an extension portion 202. A reinforcing rib 114 connected to the extension portion 202 is also provided within the inner recess 111. The extension portion 202 is formed with a through hole for the reinforcing rib 114 to pass through. The reinforcing rib 114 is located at both ends of the extension portion 202 and is fixedly connected to the inner wall of the inner recess 111. In other words, by extending the bottom of the support rod 200, the length of the support rod 200 within the inner recess 111 is increased, thereby improving the balance of the support rod 200. The reinforcing rib 114 reinforces the extension portion 202, thereby improving the secure installation of the support rod 200 on the base 100.

[0041] In this embodiment, if Figure 1-3 As shown, at least one end of the reinforcing rib 114 extends through the inner wall of the inner recess 111 to the outside and forms a reinforcing end 115, which is welded to the outer wall of the main body 110. By extending at least one end of the reinforcing rib 114 to the outside of the inner recess 111 and forming the reinforcing end 115, and then welding it to the outer wall of the main body 110, the strength of the reinforcing rib 114 can be increased, thereby increasing the firmness of the support rod 200. In this embodiment, the reinforcing rib 114 can be formed by riveting the main body 110 and the extension portion 202 with rivets, and the head and tail of the rivet located on the outside of the main body 110 are welded to ensure that the rivet can be stably connected to the main body 110 without loosening.

[0042] In this embodiment, the support rod 200 is a circular tube, and the extension portion 202 is provided with an oblate structure with a different arc than the support rod 200, so that the width of the extension portion 202 is greater than the width of the support rod 200 located above the connection hole 113. By flattening the extension portion 202, the extension portion 202 and the connection hole 113 can be locked together during installation, generating a certain compressive force between them. The internal stress between the support rod 200 and the main body 110 ensures a stable connection between the support rod 200 and the main body 110.

[0043] In this embodiment, in order to prevent the insulator 400 from moving along the axial direction of the installed rod during installation, thereby causing a large impact force on the street code and affecting the stability of the street code, the support rod 200 also includes a reinforcement sleeve 210. A blind hole is formed at one end of the reinforcement sleeve 210, in which the end of the support rod 200 away from the base 100 is inserted, and a through hole 212 is opened radially along the reinforcement sleeve 210 for the iron core 300 to pass through.

[0044] In a further technical solution, the portion of the circumferential surface of the reinforcement sleeve 210 where the perforations 212 are formed is formed with protrusions 213 extending toward the adjacent reinforcement sleeve 210. The perforations 212 extend through the protrusions 213 along their length, allowing the iron core 300 to pass through. The provision of the protrusions 213 reduces the spacing between the two support rods 200, thereby limiting the position of the insulator 400 located between the two support rods 200, preventing excessive axial movement of the iron core 300 and reducing the amplitude of the insulator 400's movement, thereby ensuring the jitter and vibration of the street code and ensuring the stability of the street code.

[0045] In this embodiment, to facilitate installation of the insulator 400 and removal of the iron core 300, at least one anti-slip member 310 on the iron core 300 is detachably connected to one end of the iron core 300. In this embodiment, one of the anti-slip members 310 may be a protrusion fixedly mounted on one end of the iron core 300, and the other anti-slip member 310 may be a nut threadedly connected to the iron core 300.

[0046] For those skilled in the art, various other corresponding changes and deformations can be obtained based on the structure and principle disclosed by the utility model, and all of these changes and deformations fall within the protection scope of the utility model.
