[0003] Chinese patent CN109904810A discloses an interconnection bracket that can take into account weak current lines. By connecting two support plates with a bottom plate, and then installing insulators for supporting power lines and weak current lines on the two support plates, the power supply is realized The erection of the line takes into account the purpose of the erection of the weak current line; however, the bracket cannot be modified on the original power supply line, and can only be used on the newly constructed power supply line, which is not conducive to the transformation of the old power supply line

Embodiment 1

[0032] Such as Figure 1 to Figure 2 Shown is an embodiment of a street code partition extension structure of the present invention, including a support frame 1, a fixing member 2 for fixing the support frame 1, several insulating supporting seats 3, connecting parts 4, the support frame 1 and the fixing The connecting piece 2 is connected, and the insulating support base 3 is detachably connected with the supporting frame 1 through the connecting piece 4 .

[0033] As an embodiment of the present invention, the insulating support base 3 includes a main supporting unit 31, a baffle unit 32, and a connecting unit 33. Both ends of the main supporting unit 31 are respectively connected to the baffle unit 32 and the connecting unit 33, and the connecting unit 33 is detachably connected with the connector 4. The main supporting unit 31 plays the main role of supporting the weak current circuit, the baffle unit 32 is used to prevent the circuit from slipping out of the main support...

Embodiment 2

[0043] Such as Figure 3 to Figure 4 Shown is a street code embodiment of the present invention with the above-mentioned street code partition type extension structure 101, including the above-mentioned street code partition type extension structure 101, two-line street code 102 or four-line street code 103, street code The partition extension structure 101 is detachably connected to the two-line street sign 102 or the four-line street sign 103 . The street code partition type extension structure 101 is used to erect weak current lines, and the two-wire street code 102 or the four-wire street code 103 is used to erect power supply lines. The present invention can be used in newly erected lines, and can take into account the erection of weak current lines and power supply lines at the same time , and keep a sufficient safety insulation distance between the power supply line and the weak current line, and the weak current line and the power supply line can be erected separately ...

Abstract

The invention relates to the technical field of low-voltage power grid line erection auxiliary tools, and in particular, relates to a street code partition type extension structure and a street code with the extension structure; the street code partition type extension structure comprises a support frame, a fixing piece for fixing the support frame, a plurality of insulating bearing seats and a connecting piece; the supporting frame is connected with the fixing piece, and the insulating bearing seat is detachably connected with the supporting frame through the connecting piece. The invention aims to overcome the defects in the prior art, and provides the extension structure which can be mounted on a two-wire street code or a four-wire street code and is used for erecting a weak current circuit, so that the function of separately and independently routing a power supply circuit and the weak current circuit is realized, messy winding of different types of circuits is avoided, and potential safety hazards are reduced.

Description

technical field [0001] The present invention relates to the technical field of auxiliary tools for erecting low-voltage power grid lines, and more specifically, to a partitioned extension structure of a street code and a street code with the extended structure. Background technique [0002] During the construction of low-voltage power grids, because cement poles are inconvenient to use in urban streets and laneways, street codes are generally used for line erection. However, some weak current lines, including communication lines, cable TV lines and other weak current lines, were directly lapped on the street code of the power supply line due to irregular construction during construction, leaving serious safety hazards . However, there is currently no street yard that can erect weak current lines and power supply lines at the same time. Therefore, it is necessary to design an extension structure that meets insulation performance and mechanical properties and is suitable for ...
