[0033] See also Figures 1 to 3 An embodiment of the present application provides an expandable street code, including a mounting member 100, an extension member 200, a first insulator 310 and a second insulator 320. One end of the mounting member 100 is used to be set in the mounting position 10, and the other end of the mounting member 100 is provided with a first plug-in slot 110; one end of the extension member 200 is provided with a plug-in portion 210, and the plug-in portion 210 can be plugged into or detached from the first plug-in slot 110; the first insulator 310 is provided on the mounting member 100, and the second insulator 320 is provided on the extension member 200.

[0034] In the above-mentioned expandable street code, the mounting member 100 is set at the mounting position 10 and is installed with a first insulator 310. When a new low-voltage cable needs to be installed at the mounting position 10, the plug-in portion 210 of the extension member 200 is plugged into the first plug-in slot 110 of the mounting member 100 to install the extension member 200 on the mounting member 100. The new low-voltage cable is connected to the second insulator 320 on the extension member 200 to achieve the installation of the new low-voltage cable. Compared with traditional technology, the above-mentioned expandable street code can realize the installation of new low-voltage cables without setting new street codes on the wall. Therefore, even if there is no area on the wall that meets the electrical design specifications, new low-voltage cables can be installed.

[0035] In addition, the use of the expandable street code in this embodiment eliminates the need for aligning the wall, drilling holes, and other steps, and eliminates the need to dismantle the original street code, thereby improving the installation efficiency of the low-voltage cable and reducing labor intensity.

[0036] For explanation, the installation position 10 in the above embodiment can be a part of the wall of a building, or a part of the side wall of a utility pole, etc. For example, Figure 1 In the embodiment shown, the installation location 10 is a portion of a wall.

[0037] As a further explanation, the first insulator 310 on the mounting piece 100 is used to install an old low-voltage cable. When a new low-voltage cable needs to be installed at the mounting position 10, the extension piece 200 is plugged into the first plug-in slot 110 of the mounting piece 100 through the plug-in portion 210 to connect the extension piece 200 to the mounting piece 100. The second insulator 320 on the extension piece 200 can be used to install a new low-voltage cable. In this way, the new low-voltage cable can be installed without occupying the area of ​​other areas on the mounting position 10.

[0038] In one embodiment, the first insulator 310 and the second insulator 320 are made of composite insulating material to achieve full insulation wrapping and improve the overall withstand voltage level.

[0039] Furthermore, the first insulator 310 and the second insulator 320 can not only provide electrical insulation for the low-voltage cable to prevent current leakage and short-circuit accidents, but also provide mechanical support for the low-voltage cable to prevent the low-voltage wire from being deformed due to factors such as weight and wind, thereby affecting the stability of power transmission.

[0040] In one embodiment, the first insulator 310 and the second insulator 320 are ceramic insulators to improve the extreme high temperature tolerance level and prevent the occurrence of melt-through.

[0041] See also Figure 1 and Figure 3 In one embodiment, the mounting member 100 includes a mounting rod, one end of which is used to be set at the mounting position 10, and the other end of the mounting rod is provided with a first plug-in slot 110. The extension member 200 includes an extension rod, and one end of the extension rod is provided with a plug-in portion 210. The plug-in portion 210 can be plugged into the first plug-in slot 110 of the mounting rod to realize the connection between the mounting rod and the extension rod.

[0042] Furthermore, the cross-sectional diameter of the mounting rod is substantially equal to the cross-sectional diameter of the expansion rod.

[0043] See also Figure 3 In one embodiment, the plug-in portion 210 is columnar, and the shape of the first plug-in slot 110 matches the shape of the columnar plug-in portion 210 to improve the plugging stability between the plug-in portion 210 and the first plug-in slot 110 .

[0044] See also Figure 2 and Figure 3 In one embodiment, the expandable street code further includes a first connecting member 400, a first connecting hole 120 is opened on the side wall of the mounting member 100, the first connecting hole 120 is connected to the first plug-in slot 110, and a second connecting hole 211 is opened on the plug-in portion 210, and the first connecting member 400 is passed through the first connecting hole 120 and the second connecting hole 211.

[0045] The first connecting member 400 is passed through the first connecting hole 120 and the second connecting hole 211 to position the plug-in portion 210 in the first plug-in slot 110 to prevent the plug-in portion 210 from falling out of the first plug-in slot 110, thereby improving the installation stability between the extension member 200 and the mounting member 100.

[0046] Furthermore, two first connecting holes 120 are provided and are coaxially arranged. In this way, the first connecting member 400 can be sequentially passed through one of the first connecting holes 120, the second connecting hole 211 and the other first connecting hole 120, thereby realizing the positioning of the plug-in part 210, and the positioning effect is more stable.

[0047] See also Figure 2 and Figure 3 In one embodiment, the first connecting member 400 includes a first connecting rod, which is passed through one of the first connecting holes 120, the second connecting hole 211 and another first connecting hole 120, thereby achieving positioning of the plug-in portion 210, and the positioning effect is more stable.

[0048] See also Figure 4 In one embodiment, the opposite ends of the first connecting rod are designed with hexagonal heads, and a hexagonal wrench can be used to tighten them during connection so that the first connecting rod can position the plug-in portion 210, saving time and effort.

[0049] See also Figure 2 and Figure 4 In one embodiment, the first connector 400 includes a pin, which is passed through one of the first connection holes 120, the second connection hole 211 and the other first connection hole 120, thereby achieving the positioning of the plug-in part 210 without further disassembly and installation, without gaps and exposure, thereby achieving the effect of full insulation protection.

[0050] See also Figure 2 In one embodiment, the first insulator 310 defines a third connection hole 311 , and the first connector 400 passes through the third connection hole 311 .

[0051] The first connector 400 is passed through the third connection hole 311 of the first insulator 310 to achieve positioning of the first insulator 310 .

[0052] Furthermore, the first insulator 310 can rotate around the axis of the third connecting hole 311 and the first connecting member 400. In this way, when the low-voltage cable passes around the first insulator 310, it can slide through the rotation of the first insulator 310, so as to facilitate the staff to pull the wire and reduce the work intensity when installing the low-voltage cable.

[0053] See also Figure 3In one embodiment, two first connecting holes 120 are provided and are coaxially arranged, and the first connecting rod is passed through one of the first connecting holes 120, the second connecting hole 211, the other first connecting hole 120 and the third connecting hole 311, thereby realizing simultaneous positioning of the plug-in part 210 and the first insulator 310.

[0054] See also Figure 3 In one embodiment, at least two extension pieces 200 are provided, and a second plug-in slot 220 is provided at one end of the extension piece 200 away from the plug-in portion 210. Among any two adjacent extension pieces 200, the plug-in portion 210 of one extension piece 200 can be plugged into or detached from the second plug-in slot 220 of the other extension piece 200.

[0055] When it is necessary to further install a new low-voltage cable on the basis of the extension piece 200, the plug-in portion 210 of the new extension piece 200 can be plugged into the second plug-in slot 220 of the original extension piece 200 to install the new extension piece 200 on the original extension piece 200, thereby realizing the installation of the new low-voltage cable; with such an arrangement, it is possible to further install a new low-voltage cable according to the construction requirements of the power grid line expansion construction without the need to install a new street code at the installation position 10, thereby performing multi-digit expansion to adapt to complex and changeable wiring requirements.

[0056] For explanation, when more than two extension pieces 200 need to be installed on the mounting piece 100, the plug-in portion 210 of the first extension piece 200 is first plugged into the first plug-in slot 110 of the mounting piece 100, and then the plug-in portion 210 of the second extension piece 200 is plugged into the second plug-in slot 220 of the first extension piece 200. Subsequently, the plug-in portion 210 of the third extension piece 200 is plugged into the second plug-in slot 220 of the second extension piece 200, and so on, which will not be repeated here.

[0057] Further, see Figure 5 In one embodiment, the plug-in portion 210 is provided with an external thread, and the second plug-in slot 220 is provided with an internal thread. The external thread of the plug-in portion 210 is screwed with the internal thread of the second plug-in slot 220 to achieve connection between the extensions.

[0058] Similarly, see Figure 5 The first plug-in slot 110 is also provided with an internal thread, and the internal thread of the first plug-in slot 110 is screwed with the external thread of the plug-in portion 210 to achieve the connection between the mounting member 100 and the extension member 200.

[0059] See also Figure 2 and Figure 3In one embodiment, the expandable street code further includes a second connecting member 500, a fourth connecting hole 230 is provided on the side wall of the extension member 200, the fourth connecting hole 230 is connected to the second plug-in slot 220, the plug-in portion 210 is provided with a second connecting hole 211, and the second connecting member 500 is passed through the fourth connecting hole 230 and the second connecting hole 211.

[0060] The second connecting member 500 is passed through the fourth connecting hole 230 and the second connecting hole 211 to position the plug-in portion 210 in the second plug-in slot 220 to prevent the plug-in portion 210 from falling out of the second plug-in slot 220 and improve the installation reliability between the extension members 200.

[0061] Furthermore, two fourth connecting holes 230 are provided and are coaxially arranged. In this way, the second connecting member 500 can be sequentially passed through one of the fourth connecting holes 230, the second connecting hole 211 and the other fourth connecting hole 230, thereby realizing the positioning of the plug-in portion 210 in the second plug-in slot 220, and the positioning effect is more stable.

[0062] See also Figure 2 In one embodiment, the second connecting member 500 includes a second connecting rod, which is passed through one of the fourth connecting holes 230, the second connecting hole 211 and the other fourth connecting hole 230, thereby realizing the positioning of the plug-in portion 210 in the second plug-in slot 220, and the positioning effect is more stable.

[0063] See also Figure 2 In one embodiment, the second insulator 320 defines a fifth connection hole 321 , and the second connector 500 passes through the fifth connection hole 321 .

[0064] The second connecting member 500 is passed through the fifth connecting hole 321 of the second insulator 320 to achieve positioning of the second insulator 320 .

[0065] Furthermore, the first insulator 310 can rotate around the axis of the third connecting hole 311 and the first connecting member 400. In this way, when the low-voltage cable passes around the first insulator 310, it can slide through the rotation of the first insulator 310, so as to facilitate the staff to pull the wire and reduce the work intensity when installing the low-voltage cable.

[0066] See also Figure 3 In one embodiment, two fourth connecting holes 230 are provided and are coaxially arranged, and the second connecting rod is passed through one of the fourth connecting holes 230, the second connecting hole 211, the other fourth connecting hole 230 and the fifth connecting hole 321, thereby realizing simultaneous positioning of the plug-in part 210 and the second insulator 320.

[0067] See also Figure 1 and Figure 2 In one embodiment, the expandable street code further includes a positioning member 600 , one end of the positioning member 600 is disposed on the second connecting member 500 , and the other end of the positioning member 600 is used to be disposed on the installation position 10 .

[0068] After the second connector 500 positions the plug portion 210 and the second insulator 320 in the second plug slot 220 , the positioning member 600 positions the second connector 500 to prevent it from moving and affecting the overall assembly effect of the street code.

[0069] Furthermore, the positioning member 600 can prevent the second connecting member 500 from moving along the axial direction of the fourth connecting hole 230 and detaching from the fourth connecting hole 230 , thereby improving the installation stability of the street code.

[0070] See also Figure 1 and Figure 2 In one embodiment, the positioning member 600 includes a first positioning portion 610 and a second positioning portion 620. The first positioning portion 610 is arranged on the second connecting member 500, and the second positioning portion 620 is used to be arranged at the installation position 10.

The telescopic rod 621 is inserted into the telescopic groove 611 and can move back and forth along the depth direction of the telescopic groove 611.

[0071] The first positioning portion 610 and the second positioning portion 620 are moved closer to or further away from each other through the cooperation between the telescopic slot 611 and the telescopic rod 621, thereby adjusting the overall length of the positioning member 600. In this way, when the same mounting member 100 is expanded and installed with different numbers of extension members 200, the second connecting member 500 can be positioned by adjusting the length of the positioning member 600, without the need to replace positioning members 600 of different lengths, thereby reducing costs.

[0072] exist Figure 2 In the illustrated embodiment, the first positioning portion 610 is provided with a telescopic slot 611 , and the second positioning portion 620 is provided with a telescopic rod 621 .

[0073] Furthermore, when a plurality of extension pieces 200 are installed on the same installation piece 100 , the first positioning portion 610 is usually installed on the second connecting piece 500 farthest from the installation position 10 , thereby positioning all the extension pieces 200 .

[0074] See also Figure 1 and Figure 2In one embodiment, there are at least two positioning members 600 , one end of all positioning members 600 is connected to the second connecting member 500 , and the other ends of all positioning members 600 are spaced apart at the mounting position 10 along the first direction of the mounting position 10 .

[0075] At least two positioning members 600 can provide a more reliable positioning effect for the second connecting member 500, thereby preventing the second connecting member 500 from falling off and causing the street code to fall.

[0076] Furthermore, at least two positioning members 600 can simultaneously provide a diagonal pulling effect for the second connecting member 500, thereby improving the overall load-bearing performance of the street code.

[0077] For further information, see Figure 4 In one embodiment, the positioning member 600 adopts a basket bolt tensioning design to achieve free fixation and positioning, thereby improving overall applicability.

[0078] For explanation, the first direction of the mounting position 10 is parallel to the ground, that is, Figure 1 and Figure 2 The A direction in will not be described here.

[0079] See also Figure 2 In one embodiment, the first positioning portion 610 is in a sheet shape, and the sheet-shaped first positioning portions 610 can be stacked on each other and connected to the second connecting member 500 .

[0080] See also Figure 2 In one embodiment, the first positioning portion 610 is provided with a mounting hole 612 for the second connecting member 500 to pass through, so as to achieve connection between the first positioning portion 610 and the second connecting member 500 .

At least two extension members 200 are arranged in a one-to-one correspondence with the mounting members 100 to simultaneously install and position at least two second insulators 320. The arrangement of the base 700 can improve the installation stability and installation strength of the mounting member 100, and prevent the mounting member 100 from falling off and causing damage to the street code.

[0083] For explanation, the second direction of the base 700 is the length direction of the base 700, that is, Figure 1 and Figure 2 The B direction in will not be described here.

[0084] Furthermore, the base 700 is in the shape of a cuboid, and the length direction of the base 700 is perpendicular to the ground, that is, the second direction is perpendicular to the first direction.

[0085] See also Figure 4 In one embodiment, at least two bases 700 are provided, and at least two bases 700 can be spliced ​​together, thereby enabling the street code to achieve vertical expansion.
