Description

Technical Field

[0001] This utility model belongs to the technical field of electricity metering boxes, and relates to automatic locking, particularly an electricity metering box that can be automatically locked. Background Technology

[0002] An electricity metering box is a device used to measure and record electricity consumption, widely used in industrial, commercial, and residential power systems. It mainly consists of an electricity meter, terminals, and protection devices, and has the function of real-time monitoring of electricity consumption and recording power and energy consumption data. Some electricity metering boxes also have communication capabilities, allowing data to be transmitted to a centralized monitoring system or cloud platform. Furthermore, they are typically equipped with overload and short-circuit protection functions, and displays allow users to easily view electricity usage in real time. They must also comply with relevant national or international standards to ensure accuracy and reliability. By using electricity metering boxes, users can more effectively manage electricity consumption, optimize their electricity usage structure, and thus reduce electricity bills.

[0003] However, in the current use of some electricity metering boxes, the box doors are mostly locked manually by workers. Manual locking depends on the worker's attention and operating habits. If the worker is negligent during operation, the box door may not be fully locked, thereby increasing the risk of unauthorized access to the equipment or electricity theft. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatically locking electricity metering box. The technical problem this utility model aims to solve is that the box door is mostly locked manually by workers. Manual locking depends on the worker's attention and operating habits. If the worker is negligent during operation, the box door may not be fully locked, thereby increasing the risk of unauthorized access to the equipment or electricity theft.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatically locking electricity metering box includes a box body with two doors rotatably connected to one side of the box body. The two doors are configured to cooperate with the box body. A common support column is provided between the two doors, and the support column is fixedly connected to one side of the box body. A first storage groove is formed on the surface of the support column near the door. Two locking plates are slidably connected inside the first storage groove. The two locking plates are respectively fixedly connected to one side of the two doors. A second storage groove is formed at both ends of the first storage groove. An electric push rod is fixedly connected inside each of the two second storage grooves. A support plate is fixedly connected to the output end of each of the two electric push rods. A locking pin is fixedly connected to the surface of each of the two support plates near the two locking plates. A locking groove is formed on the surface of each of the two locking plates near the locking pin, and the locking groove and the locking pin are configured to cooperate with each other. An adjustment mechanism for adjusting the locking pin is provided on one side of one of the doors. The locking pin can prevent the door from being not fully locked.

[0006] As a further embodiment of this utility model, the adjustment mechanism includes a fingerprint lock, which is fixedly connected to one side of the door. Two third storage slots are symmetrically formed on the top of the fingerprint lock. Limiting rods are slidably connected inside each of the two third storage slots. The tops of the two limiting rods are fixedly connected to the same protective cover, which is slidably connected to one side of the fingerprint lock. Tension springs are sleeved on the surfaces of the two limiting rods. One end of each tension spring is fixedly connected to one side of the protective cover, and the other end is fixedly connected to one side inside the third storage slot. Two limiting grooves are symmetrically formed on the surface of the fingerprint lock. Limiting plates are slidably connected inside each of the two limiting grooves. The two limiting plates are fixedly connected to one side inside the protective cover. A constraint mechanism for restraining the door is provided at the bottom of the door. The fingerprint lock allows for adjustment of the electric push rod.

[0007] As a further embodiment of this utility model, the constraint mechanism includes a locking disc, which is fixedly connected to the bottom of the box. The top of the locking disc has multiple positioning grooves, which are evenly spaced in an arc shape. A sliding groove is formed on the surface of the box door near the locking disc. Two support rods are symmetrically and fixedly connected inside the sliding groove. The same adjusting plate is slidably fitted onto the surfaces of the two support rods. A positioning post is fixedly connected to the bottom of the adjusting plate and slidably connected to the bottom of the box door. The positioning post and the positioning groove are mutually coordinated. Springs are fitted onto the surfaces of both support rods. One end of each spring is fixedly connected to one side of the sliding groove, and the other end of each spring is fixedly connected to one side of the adjusting plate. The positioning post helps to constrain the box door.

[0008] As a further embodiment of this utility model, two second sensors are fixedly connected inside the first storage slot, and each of the two second sensors is equipped with a first sensor. The two first sensors are respectively fixedly connected to one side of the two card plates.

[0009] The beneficial effects of this utility model are as follows: 1. This utility model, by employing a technical solution of moving the locking column via an electric push rod, avoids the situation where the cabinet door is not fully locked. This effectively solves the problem that cabinet doors are mostly locked manually by workers, which relies on the worker's attention and operating habits. If the worker is negligent during operation, the cabinet door may not be fully locked, increasing the risk of unauthorized access or electricity theft. When the cabinet door needs to be locked, it is first rotated to one side of the cabinet body. A support column is installed on one side of the cabinet body, and a first storage groove is opened on one side of the support column. A retaining plate is installed on one side of the cabinet door. The mechanism works in conjunction with the first storage slot. As the door rotates continuously, the card plate enters the first storage slot. Inside the first storage slot, a second sensor is installed. This second sensor works in conjunction with the first sensor on one side of the card plate. When the card plate is in place, the first sensor contacts the second sensor and transmits information to the controller. The controller then activates the electric push rod. A locking pin is installed on the output shaft of the electric push rod. This locking pin engages with a locking groove at one end of the card plate. When the electric push rod is activated, the locking pin is inserted into the locking groove, thus locking the door. Attached Figure Description
