Description

Technical Field

[0001] The utility model relates to the technical field of electric meter cabinets, in particular to a novel electric meter cabinet which is convenient for replacing electric meters. Background Technique

[0002] The Chinese invention patent with the publication number CN112864854B discloses an electric meter cabinet facilitating the replacement of an electric meter, which includes an electric meter cabinet body. A fixed cross bar made of insulating material is arranged in the electric meter cabinet body. An electric meter mounting seat for installing an electric meter is connected to the fixed cross bar. The electric meter mounting seat includes a bottom plate, a boss is arranged on the bottom plate, and a conductive plug post for connecting with the electric meter is arranged at the upper end of the boss; a sheath hole is arranged at the upper end of the boss, the conductive plug post passes through the sheath hole, and an insulating sheath that can move axially along the conductive plug post is sleeved on the conductive plug post. The sheath hole is a stepped hole, which is composed of a lower hole and an upper hole. The lower hole is located below the upper hole and the diameter of the lower hole is larger than that of the upper hole. A stepped surface is formed between the lower hole and the upper hole. A return spring is arranged between the lower end of the insulating sheath and the lower end of the sheath hole; a lower flange is arranged at the lower end of the insulating sheath, the lower flange is located in the lower hole, and the diameter of the lower flange is larger than that of the upper hole and smaller than that of the lower hole; a second piston hole is arranged at the upper end of the lower flange, a second piston is arranged in the second piston hole, a second ejector rod is connected to the upper end of the second piston, a second air chamber is formed between the second piston and the lower end of the second piston hole, and a second spring is arranged between the second piston and the lower end of the second piston hole; a second inflation ring is arranged around the side surface of the lower flange, and the second air chamber is connected to the second inflation ring through a second air duct. In the present invention, when the electric meter is installed on the electric meter mounting seat, the upper end of the insulating sheath abuts against the lower end of the electric meter, and the insulating sheath moves to the lowest position. At this time, the conductive plug post exposes from the insulating sheath and is inserted into the wiring jack of the electric meter. The insulating sheath is sleeved on the conductive plug post and can move axially along the conductive plug post. When the electric meter is pulled out from the electric meter mounting seat, the insulating sheath moves upward under the action of the return spring until the lower flange abuts against the stepped surface, so that the insulating sheath automatically covers the conductive plug post, thus avoiding the operator from getting an electric shock due to accidentally touching the conductive plug post. When the lower flange approaches the stepped surface, the second ejector rod arranged on the lower flange first contacts the stepped surface. After the ejector rod contacts the stepped surface, it will drive the second piston to move downward, so that the volume of the second air chamber shrinks, and the air in the second air chamber is filled into the second inflation ring, making the second inflation ring gradually expand. During the process of the second inflation ring gradually expanding, the second inflation ring is gradually tightened with the inner wall of the lower hole, so that the friction force between the lower flange and the inner wall of the lower hole gradually increases, thus playing a role in decelerating the insulating sheath, enabling the insulating sheath to stop slowly and reducing the impact force between the lower flange and the stepped surface; at the same time, when the insulating sheath moves to the highest position, the second inflation ring is in an expanded state, and the second inflation ring is tightened with the inner wall of the lower hole, so that the insulating sheath can be more stably maintained at this position. In this way, even if the insulating sheath is slightly accidentally touched by the operator, it is not easy to move downward, thus effectively reducing the risk of the operator getting an electric shock after accidentally touching the insulating sheath.When the conductive plug is inserted into the wiring jack on the electricity meter, the upper end of the insulating sheath abuts against the lower end of the electricity meter and moves downward. During the downward movement of the insulating sheath, the second ejector rod moves away from the stepped surface, and the piston moves upward and resets under the action of the second spring, causing the volume of the second air chamber to increase. The gas in the second inflatable ring is sucked into the second air chamber, causing the second air chamber to be in a contracted state and separated from the inner wall of the lower hole, thereby reducing the resistance when the insulating sheath moves downward.

However, bolts are required to fix the electricity meter to the fixed crossbar. Therefore, the disassembly and assembly of the electricity meter are relatively inconvenient, and the disassembly and assembly of the electricity meter cannot be completed quickly and completely.
