Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The following detailed description is exemplary in nature and is intended to provide further details of the invention. Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the invention.
The embodiment of the utility model provides a low pressure conducting rod extension device links together cracked conducting rod A and sealed lid bowl 1, conducting rod extension part 2, when adding long low pressure side pole fast, guarantees that vase sleeve pipe 3 seals well, the low pressure current-carrying capacity is not lost.
A low voltage conductive rod lengthening device, comprising: a sealing cover bowl 1 and a conducting rod lengthening part 2.
As shown in fig. 1-2, the sealing cover bowl 1 is a hexagonal internal thread sealing cover bowl, a thread through hole 11 is formed in the sealing cover bowl 1, a bowl-shaped groove 12 is formed around the thread through hole 11, and cutting is performed by taking the thread through hole of the hexagon nut as a center to obtain the sealing cover bowl 1.
As shown in fig. 3 to 4, the conducting rod lengthening member 2 includes a connecting member 21 and an lengthening member 22, the lengthening member 22 is a screw, the connecting member 21 is in a hexagonal nut shape, and a threaded hole 211 is provided at one end of the hexagonal nut-shaped connecting member 21; the other end is fixedly connected with the lengthening piece 22, and a threaded hole is arranged at the center of the lengthening piece.
As shown in fig. 5, the threaded through hole 11 and the threaded hole 211 are respectively in threaded fit with the broken conducting rod a. The sealing cover bowl 1 is used for being screwed on the broken conducting rod A, and a sealing rubber bead 4 is arranged between the sealing cover bowl 1 and the porcelain bottle sleeve 3.
After the conventional sealing cover bowl B is removed, the sealing cover bowl 1 is screwed on the sealing rubber beads 4, and then the conducting rod lengthening part 2 is screwed on the broken conducting rod a through the threaded hole 211 on the connecting part 21 (since the sealing cover bowl 1 is a combined design of the conventional sealing cover bowl B and the nut C, a part of the length can be saved, the upper end of the broken conducting rod a is exposed after the sealing cover bowl 1 is screwed), and is aligned with the edge of the sealing cover bowl 1. This relatively lengthens the length of the fracture conductor bar a and increases the conductor contact surface to which the drainage device can be securely mounted.
