Description

Technical Field

[0001] This utility model belongs to the technical field of electricity meters, and in particular relates to a card slot protection structure for electricity meters. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy. It measures various electrical quantities. When using an electricity meter, it's important to note that under low voltage (not exceeding 500 volts) and low current (tens of amps), the electricity meter can be directly connected to the circuit for measurement. Under high voltage or high current conditions, the electricity meter cannot be directly connected to the line and must be used in conjunction with a voltage transformer or current transformer. A card-type electricity meter combines electricity metering and prepaid functions. To protect the card slot from damage during the uninserted phase, a corresponding card slot protection structure is required.

[0003] However, existing protective structures mostly only protect the surface of the card slot, without sealing the interior. Therefore, dirt easily accumulates inside, making cleaning difficult. Furthermore, the protective structure is inconvenient to adjust, which can affect the efficiency of the card insertion process. To address these issues, we provide a card slot protection structure for electricity meters. Utility Model Content

[0004] The purpose of this utility model is to provide a card slot protection structure for an electricity meter. Through the cooperation of the protective plate and the foam block, the electricity meter body is shielded to prevent dust accumulation inside. At the same time, the cooperation of the L-shaped strip and the protective plate enables the adjustment of the position of the protective plate to avoid affecting the card insertion.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a card slot protection structure for an electricity meter, including an electricity meter body; a protective plate is provided at the slot position on the side of the electricity meter body; L-shaped strips are provided on the front sidewalls of the electricity meter body on the left and right sides of the protective plate; U-shaped plates are provided on the lower end face of the L-shaped strips and bolted to the lower end face of the electricity meter body; and foam blocks are fixed to the side of the protective plate and inserted into the slot.

[0007] The present invention is further configured such that the inner sidewalls of the U-shaped plate are all fixed with shafts, and the L-shaped strip is screwed onto the shafts through the rotating holes opened at the lower end.

[0008] The present invention is further provided with a positioning strip located at the front of the protective plate, and the left and right parts of the positioning strip are provided with movable holes.

[0009] The present invention is further configured such that a T-shaped opening is provided on the front side wall of the L-shaped strip, penetrating its upper end face, and T-shaped strips are fixed on the left and right sides of the rear side wall of the positioning strip, which are inserted into the T-shaped opening.

[0010] The present invention is further configured such that movable rods passing through the interior of the movable holes are fixed on the left and right parts of the front side wall of the protective plate, and springs are sleeved on the movable rods located between the protective plate and the positioning strip, and the two ends of the springs abut against the opposite end faces of the protective plate and the positioning strip, respectively.

[0011] The present invention is further configured such that a rotating block is provided on the end face of the movable rod passing through the movable hole, and the diameter of the rotating block is larger than the diameter of the movable hole.

[0012] The present invention is further configured such that each end face of the movable rod connected to the rotating block is provided with a screw hole, and a screw with a spiral inside the screw hole is fixed to the end face of the rotating block.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 5 This utility model is a card slot protection structure for an electricity meter. Through the cooperation of the protection plate 2 and the foam block 201, the electricity meter body 1 is shielded to prevent dust accumulation inside. At the same time, the cooperation of the L-shaped strip 4 and the protection plate 2 enables the adjustment of the position of the protection plate 2 to avoid affecting the card insertion.

[0027] Specifically, the electricity meter body 1 has a protective plate 2 located at the socket position on the side of the electricity meter body 1. L-shaped strips 4 are provided on the front sidewalls of the electricity meter body 1 on the left and right sides of the protective plate 2. U-shaped plates 401 are bolted to the lower end face of the L-shaped strips 4. Foam blocks 201 are fixed to the side of the protective plate 2 and inserted into the socket. Shaft rods 402 are fixed to the inner sidewalls of the U-shaped plates 401. The L-shaped strips 4 are screwed onto the shaft rods 402 through the rotating holes 403 opened at the lower end. A positioning strip 3 is provided at the position directly in front of the protective plate 2. Movable holes 302 are opened through the left and right parts of the positioning strip 3.

[0028] The operation process of this embodiment is as follows: By setting and using the above structure, the protection plate 2 is installed at the socket position on the front side of the electricity meter body 1. The protection plate 2 will shield the socket, thereby protecting the internal structure of the socket and preventing damage to it. At the same time, a corresponding foam block 201 is installed on the side of the protection plate 2. Therefore, when the protection plate 2 is rotated to contact the front wall of the electricity meter body 1, the foam block 201 on the side wall of the protection plate 2 will be directly inserted into the socket of the electricity meter body 1, sealing the inside of the socket and preventing dirt from accumulating inside. At the same time, the protection plate 2 is moved away from the electricity meter body 1, so that the protection plate 2 drives the foam block 201 to disengage from the socket of the electricity meter body 1. The L-shaped strip 4 is then rotated, thereby rotating the protection plate 2 from the front position of the electricity meter body 1 to the lower position, thereby reducing the impact on the operation of the electricity meter body 1 when inserting the card.

[0029] Example 2

[0030] Please see Figure 3 and Figure 5 Based on Example 1, the T-shaped strip 301 and the T-shaped opening 404 work together to enable the positioning strip 3 and the protective plate 2 to work together.

[0031] Specifically, the front side wall of the L-shaped strip 4 has a T-shaped opening 404 that penetrates its upper end face, and the left and right sides of the rear side wall of the positioning strip 3 are fixed with T-shaped strips 301 that are inserted into the T-shaped opening 404.

[0032] The operation process of this embodiment is as follows: Align the positioning strip 3 with the L-shaped strip 4, and insert the T-shaped strip 301 into the T-shaped opening 404. Through the limiting cooperation between the T-shaped opening 404 and the T-shaped strip 301, the L-shaped strip 4 and the positioning strip 3 are assembled and connected together, ensuring that the positioning strip 3 and the protective plate 2 can work together.

[0033] Example 3

[0034] Please see Figure 2 , Figure 4 and Figure 5 Based on Example 1, the positioning strip 3, L-shaped strip 4 or protective plate 2 can be individually disassembled and replaced by using the cooperation between screw 203 and screw hole 205.

[0035] Specifically, movable rods 204 are fixed to the left and right sides of the front sidewall of the protective plate 2, passing through the interior of the movable hole 302. Springs 206 are fitted on the movable rods 204 located between the protective plate 2 and the positioning strip 3, and the two ends of the springs 206 abut against the opposite end faces of the protective plate 2 and the positioning strip 3, respectively. Rotating blocks 202 are provided on the end faces of the movable rods 204 that pass through the movable hole 302, and the diameter of the rotating blocks 202 is larger than the diameter of the movable hole 302. Screw holes 205 are opened on the end faces of the movable rods 204 that connect to the rotating blocks 202, and screws 203 are fixed to the end faces of the rotating blocks 202, which are screwed inside the screw holes 205.

[0036] The operation process of this embodiment is as follows: by pulling the rotating block 202, the rotating block 202 will drive the movable rod 204 to move, and thus drive the protection plate 2 to move synchronously, so that the foam block 201 is moved out of the socket of the power meter body 1. At the same time, when it is necessary to disassemble the protection plate 2 and the positioning strip 3, the rotating block 202 is rotated, so that the screw 203 on the rotating block 202 is dislodged from the screw hole 205, and the positioning strip 3, L-shaped strip 4 or protection plate 2 can be replaced individually.
