Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to an anti-theft electricity meter. Background Technology

[0002] An electricity meter, also known as an energy meter, is an instrument used to measure electrical energy consumption. It is mainly used to record the electricity consumption of end users and serves as the basis for electricity billing. It is widely used in households, industries, and other fields and is a key device for electricity system metering and billing.

[0003] The wiring part on the electricity meter has a protective cover to shield and protect the wiring part. The protective cover is usually connected and fixed to the electricity meter with screws or bolts. However, this method can be removed with just a screwdriver or wrench. These tools are quite common and cannot prevent some people from illegally connecting wires and stealing electricity.

[0004] Therefore, a theft-proof electricity meter is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-theft electricity meter in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: An anti-theft electricity meter includes a meter body, an mounting plate on the surface of the meter body, a protective cover slidably mounted on the meter body, a connecting plate on the surface of the meter body, a fixing shell on the surface of the meter body, a moving mechanism for laterally moving the fixing shell on the fixing shell, and the fixing shell is mounted on the moving mechanism. The moving mechanism is provided with an auxiliary mechanism for driving rotation in a specific manner.

[0007] Furthermore, the moving mechanism includes a screw, which is rotatably mounted on the fixed housing. A movable column is threaded onto the outer wall of the screw, and the movable column is slidably mounted on the fixed housing.

[0008] Furthermore, a fixing plate is fixedly installed on the surface of the movable column, and the fixing plate is fixedly installed on the protective cover.

[0009] Furthermore, the auxiliary mechanism includes a spring, a circular groove is provided on the screw, and the spring is fixedly installed inside the circular groove. Two irregular grooves are provided on the inner wall of the circular groove, and a circular block is slidably installed on the inner wall of the circular groove, and the circular block is fixedly installed on the spring.

[0010] Furthermore, a cylinder is slidably installed on the inner wall of the circular groove, and two fixing columns are fixedly installed on the inner wall of the cylinder. Springs are sleeved on the outer walls of the two fixing columns, and connecting rods are slidably installed on the outer walls of the two fixing columns. The connecting rods are slidably installed on the irregular groove and the cylinder. The two ends of the springs are fixedly installed on the surfaces of the two connecting rods, and pressure blocks are fixedly installed on the surfaces of the two connecting rods. The pressure blocks are slidably installed on the cylinder.

[0011] Furthermore, a knob is fixedly installed on the top of the cylinder, and the surface of the knob is provided with anti-slip texture.

[0012] The beneficial effects of this utility model are as follows: This utility model, through the setting of a protective cover, a moving mechanism, and an auxiliary mechanism, allows for the fixed installation of the electricity meter body inside the meter box via a mounting plate. The auxiliary mechanism then drives the moving mechanism, causing the protective cover to move laterally, removing the obstruction of the wiring area, allowing wiring to proceed. After wiring is completed, the auxiliary mechanism drives the moving mechanism to reset the protective cover, providing protection. Finally, removing the driving component of the auxiliary mechanism prevents the moving mechanism from being driven directly; only the auxiliary mechanism can drive it. This design prevents unauthorized personnel from moving the protective cover and illegally wiring to steal electricity. It allows for precise adjustment of the protective cover's position, avoiding unauthorized wiring by non-technical personnel. The system is simple to operate and highly practical.

[0020] like Figure 1-3 As shown, an anti-theft electricity meter includes a meter body 1, a mounting plate 2 disposed on the surface of the meter body 1, a protective cover 3 slidably disposed on the meter body 1, a connecting plate 4 disposed on the surface of the meter body 1, a fixing shell 5 disposed on the surface of the meter body 1, and a moving mechanism 6 disposed on the fixing shell 5 for laterally moving the fixing shell 5, and the fixing shell 5 is disposed on the moving mechanism 6; as shown Figure 1-4 As shown, specifically, the moving mechanism 6 includes a screw 601, which is rotatably mounted on the fixed housing 5. A moving column 602 is threadedly mounted on the outer wall of the screw 601, and the moving column 602 is slidably mounted on the fixed housing 5. A fixing plate 603 is fixedly mounted on the surface of the moving column 602, and the fixing plate 603 is fixedly mounted on the protective cover 3.

[0021] More specifically, when the screw 601 rotates, it can drive the moving column 602 to move laterally, and the fixed plate 603 and the protective cover 3 move accordingly, thereby adjusting the position of the protective cover 3.

[0022] The moving mechanism 6 is provided with an auxiliary mechanism 7 for driving rotation in a specific manner; such as Figure 1 , Figure 3-4 As shown, specifically, the auxiliary mechanism 7 includes a spring 703, a circular groove 701 on the screw 601, and the spring 703 fixedly installed inside the circular groove 701. Two irregularly shaped grooves 702 are formed on the inner wall of the circular groove 701. A circular block 704 is slidably installed on the inner wall of the circular groove 701 and fixedly installed on the spring 703. A cylinder 705 is slidably installed on the inner wall of the circular groove 701, and two fixing posts 706 are fixedly installed on the inner wall of the cylinder 705. Spring 707 is fitted on the outer wall of 6. Connecting rods 708 are slidably installed on the outer wall of the two fixed columns 706. The connecting rods 708 are slidably installed on the irregular groove 702 and the cylinder 705. The two ends of spring 707 are fixedly installed on the surface of the two connecting rods 708. Pressure blocks 709 are fixedly installed on the surface of the two connecting rods 708. Pressure blocks 709 are slidably installed on the cylinder 705. A knob 710 is fixedly installed on the top of the cylinder 705. Anti-slip texture is formed on the surface of the knob 710.

[0023] More specifically, the opening of the circular groove 701 of the screw 601 is blocked by the cooperation of spring 703 and circular block 704, preventing non-technical personnel from knowing the shape of the irregular groove 702. When the screw 601 is rotated, the two pressure blocks 709 are pressed in advance, causing the two connecting rods 708 to move closer to each other and retract into the cylinder 705, compressing the two springs 707. Then, the cylinder 705 is inserted into the circular groove 701, and the circular block 704 is pushed, compressing the spring 703. At this time, the two pressure blocks 709 can be released, and one end of the two connecting rods 708 is in contact with the circular groove 701. Then, the cylinder 705 is rotated. When one end of the connecting rod 708 rotates to correspond with the irregular groove 702, under the restoring force of the second spring 707, one end of the connecting rod 708 is inserted into the irregular groove 702. Then, the pushing on the cylinder 705 is released. Under the restoring force of the first spring 703, the round block 704 pushes the connecting rod 708. The connecting rod 708 slides in the irregular groove 702 and abuts against it. At this time, the knob 710 is rotated, which will cause the screw 601 to rotate accordingly, thereby driving the screw 601 in a specific way and preventing non-technical personnel from driving the screw 601 privately.

[0024] In summary, during use, the main body 1 of the electricity meter is fixedly installed inside the meter box using the mounting plate 2. Then, the moving mechanism 6 is driven by the auxiliary mechanism 7, which causes the protective cover 3 to move laterally, removing the obstruction to the wiring area. Wiring can then be performed. After wiring is completed, the moving mechanism 6 can be driven by the auxiliary mechanism 7 to reset the protective cover 3, providing protection. Finally, removing the driving component of the auxiliary mechanism 7 prevents the moving mechanism 6 from being driven by the auxiliary mechanism 7 alone. This prevents unauthorized personnel from moving the protective cover 3 and illegally wiring to steal electricity. It allows for the adjustment of the position of the protective cover 3 in a specific way, avoiding unauthorized wiring by unauthorized personnel. The operation is simple and highly practical.
