In order to improve the efficiency of meter reading, infrared meter reading devices are often used to directly read the meter value to reduce meter reading time and improve accuracy. The working principle of infrared meter reading devices is based on infrared remote control signals, which transmit data through modulation, transmission and reception. They are usually composed of infrared transmitters, infrared receivers and data processing units, and use the characteristics of infrared rays to transmit and receive data. The infrared meter reader transmits infrared signals to metering equipment such as electric energy meters, then receives the reflected infrared signals and converts them into electrical signals;

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] See also Figure 1-11The present invention provides a technical solution: a portable electric energy meter data reading and verification device, comprising a verification device 1, an infrared receiving port 10 is provided at one side of the outer surface of the verification device 1, and a connecting piece 3 for fixing the verification device 1 is provided at a position corresponding to the infrared receiving port 10 on the outer surface of the verification device 1. The verification device 1 is hung on the surface of the electric meter through the connecting piece 3. The user can hang different verification devices 1 on different electric meters at the same time, and remove them one by one after the data reading is completed. It is no longer necessary to wait for the verification device 1 to read the data before removing it, thereby improving the efficiency of meter reading and reducing the workload of the user;

[0035] The connector 3 includes an embedding groove 36, which is provided at a position corresponding to the infrared receiving port 10 on the outer surface of the inspection instrument 1. A suction cup 30 is provided inside the embedding groove 36. A positioning cavity 26 is provided on the inner surface of the embedding groove 36. A positioning body 32 is slidably connected inside the positioning cavity 26. Both the positioning cavity 26 and the positioning body 32 are T-shaped structures. The positioning body 32 is inside the positioning cavity 26 and slides along the positioning cavity 26. The end of the positioning body 32 is movably connected to the suction cup 30. By setting the suction cup 30, the user aligns the suction cup 30 with the electric meter and presses it to suck the suction cup 30 onto the surface of the electric meter. The overall structure of the positioning cavity 26 and the positioning body 32 are consistent. The side view of the disc part of the positioning cavity 26 and the disc part of the positioning body 32 are both rectangular in design, and the positioning cavity 26 is larger than the positioning body 32 as a whole. The positioning body 32 is stuck inside the positioning cavity 26. After the suction cup 30 is adsorbed on the surface of the electric meter, it is convenient to fine-tune the position of the verification instrument 1, so as to adjust the infrared receiving port 10 to align with the infrared transmitting port of the electric meter;

[0036] An adjusting member 2 for adjusting the internal pressure of the suction cup 30 is provided at one end of the inner surface of the positioning cavity 26 away from the suction cup 30, and the adjusting member 2 includes a flow groove 25 connected to the positioning cavity 26, and a pressing groove 20 is provided at one end of the inner surface of the flow groove 25 away from the positioning cavity 26, and a pressing plate 21 is slidably connected inside the pressing groove 20. By setting the adjusting member 2, when the user needs to remove the verification instrument 1, air is pumped into the suction cup 30 through the adjusting member 2 to break the negative pressure state inside the suction cup 30, thereby facilitating the user to remove the verification instrument 1 and reducing the user's physical labor.

[0037] The connecting member 3 includes a contraction groove 34, which is provided on the outer surface of the front end of the positioning body 32, and the inner surface of the contraction groove 34 is provided with a through groove 33 that penetrates the positioning body 32, and the contraction groove 34 is communicated with the flow groove 25 through the through groove 33, and a contraction block 38 is slidably connected inside the contraction groove 34, and a spring 35 is fixedly connected between the contraction block 38 and the contraction groove 34, and the end of the contraction block 38 away from the contraction groove 34 is fixedly connected to the telescopic block 28, and a telescopic groove 40 is provided at the front end of the contraction block 38 at a position corresponding to the telescopic block 28, and the telescopic block 28 is slidably connected inside the telescopic groove 40, and the telescopic block 28 is slidably connected inside the telescopic groove 40. The front end of the retractable block 28 is fixedly connected to the suction cup 30, and an extrusion groove 50 is provided at the center of the suction cup 30 and the telescopic block 28. A matching extrusion tube 49 is slidably connected inside the extrusion groove 50, and a flow channel 46 is provided at the end of the extrusion groove 50 away from the extrusion tube 49, and a slide groove 44 is provided at the end of the flow channel 46 away from the extrusion tube 49, and a clamping block 43 is slidably connected inside the slide groove 44, and a spring 45 is fixedly connected between the clamping block 43 and the slide groove 44, and a clamping groove 42 is provided at the corresponding position of the telescopic groove 40 and the clamping block 43, and an interpenetrating tube 41 is fixedly connected to the end of the extrusion tube 49 away from the suction cup 30. The insertion tube 41 passes through the telescopic block 28 and the contraction block 38, and extends to the inside of the through groove 33; when the suction cup 30 contacts the electric meter, the user presses the verification instrument 1 to squeeze out the air on the surface of the suction cup 30, and at this time the squeezing tube 49 contacts the surface of the electric meter, and continues to press the suction cup 30 to force the squeezing tube 49 to be squeezed and move along the squeezing groove 50, and the squeezing tube 49 squeezes the air inside the flow channel 46 into the slide groove 44, and pushes the card block 43 to slide inside the slide groove 44 and disengage from the card groove 42, so that the suction cup 30 and the telescopic block 28 are in a telescopic sliding state. Since the telescopic block 28 is fixedly connected to the contraction block 38, the sliding of the suction cup 30 The direction is consistent with the sliding direction of the shrinkage block 38 inside the shrinkage groove 34. After the telescopic block 28 and the shrinkage block 38 lose the restrictions of the card block 43 and the card slot 42, under the traction of the elastic force of the spring three 35, the shrinkage block 38 moves in the direction of the spring three 35 inside the shrinkage groove 34, so that part of the suction cup 30 is embedded in the embedding groove 36. At this time, the gap between the verification instrument 1 and the electric meter is reduced to a minimum, preventing external light from entering the gap, thereby improving the anti-interference ability of the infrared receiving port 10 and the infrared transmitting port of the electric meter. The user pulls the suction cup 30 to reset the suction cup 30, and the card block 43 is automatically inserted into the card slot 42 under the action of the elastic force of the spring three 35.

[0038] The outer diameter of the insertion tube 41 is smaller than the extrusion groove 50. When the extrusion tube 49 is expanded and contracted, the air inside the extrusion groove 50 is squeezed to drive the block 43 to move, wherein the inside of the extrusion groove 50 may be liquid to achieve the maximum driving effect. The insertion tube 41 and the extrusion tube 49 have the same inner diameter to facilitate the flow of gas. The diameter of the expansion groove 40 is larger than the diameter of the contraction groove 34. The inner surface of the positioning cavity 26 is fixedly connected with a spring 5 27. The end of the spring 5 27 contacts the annular outer surface of the positioning body 32, and the spring 5 27 provides certain support for the positioning body 32.

[0039] The adjusting member 2 further comprises a pressing rod 22, which is fixedly connected to the outer surface of the upper end of the pressing plate 21, and the pressing rod 22 extends to the outside of the verification instrument 1. A spring 1 23 is fixedly connected between the pressing plate 21 and the pressing groove 20, and a spring 24 is fixedly connected to the lower end of the inner surface of the pressing groove 20. The user can squeeze the pressing rod 22 before squeezing the suction cup 30, and the pressing rod 22 will drive the pressing plate 21 to slide inside the pressing groove 20 to discharge the gas inside the flow groove 65 through the through groove 33, the insertion tube 41 and the squeezing tube 49, thereby pressing the suction cup 30. 0 is blown on the area that is about to contact, so as to reduce the dust on the surface of the electric meter and improve the contact effect between the suction cup 30 and the electric meter. When the suction cup 30 needs to be removed after being adsorbed and fixed, the user continues to press the pressing rod 22, and the pressing rod 22 will continue to move downward and squeeze the spring 24. At this time, the spring 24 supports part of the space inside the pressing groove 20, and the gas inside the part of the space is discharged again to offset the negative pressure state inside the suction cup 30, so that the user can remove the verification instrument 1. The elastic force generated by the spring 24 is greater than the pressure generated by the negative pressure inside the suction cup 30, thereby increasing the stability of the structure.

[0040] The length of the spring 24 is smaller than that of the spring 1 23 , and the diameter of the circulation groove 25 is larger than the diameter of the through groove 33 , leaving a margin for adjusting the position of the positioning body 32 inside the positioning cavity 26 . No matter where the positioning body 32 is located inside the positioning cavity 26 , the through groove 33 always corresponds to the circulation groove 25 .

[0041] Embodiment 2

[0042] The connecting member 3 also includes a positioning groove 60, which is opened on the annular inner surface of the positioning cavity 26. A positioning rod 61 is slidably connected inside the positioning groove 60, and one end of the positioning rod 61 is in contact with the positioning body 32. The positioning grooves 60 are in several groups and are distributed along the central annular array of the positioning body 32. In this embodiment, a fixing method for the positioning body 32 is added to improve the accuracy of fine-tuning.

[0043] The end of the positioning rod 61 that contacts the positioning body 32 is designed with an arc-shaped structure to ensure that the positioning rod 61 can contact the positioning body 32. The positioning rod 61 is designed with a hollow structure to reduce air resistance. The positioning rod 61 is magnetic, and the positioning body 32 is made of magnetic metal. The positioning rod 61 is magnetically connected to the positioning body 32, which ensures that when the positioning body 32 is at any position inside the positioning cavity 26, the positioning rod 61 will move along the positioning groove 60 toward the positioning body 32, and the positioning rod 61 and the positioning groove 60 remain in close fit to support the positioning body 32.

[0044] The connector 3 also includes an annular cavity 64, which is provided at the rear end of the inner surface of the positioning cavity 26. A slot 66 is provided at one end of the annular cavity 64 away from the positioning cavity 26, and the slot 66 is designed as an annular structure. A positioning ring 62 is slidably connected inside the slot 66. A positioning pin 63 is fixedly connected to one end of the positioning ring 62 away from the annular cavity 64. The positioning pin 63 extends into the interior of the positioning groove 60 and contacts the positioning rod 61. A flow groove 65 is provided at a position corresponding to the positioning body 32 and the annular cavity 64. One end of the flow groove 65 away from the annular cavity 64 is connected to the contraction groove 34 and the other end is connected to the annular cavity 64. Through the design of the flow groove 65, the telescopic block can be used to 28 and the shrinkage block 38 move toward the inside of the shrinkage groove 34, and the shrinkage groove 34 is filled with liquid. When the shrinkage block 38 moves along the shrinkage groove 34, the liquid in the shrinkage groove 34 is pressed out through the annular cavity 64. The pressed liquid pushes the positioning ring 62 through the slot 66 to drive the positioning pin 63 to move toward the positioning rod 61, and contacts with the surface of the positioning rod 61 to fix the positioning body 32, thereby increasing the stability of the positioning body 32. After the suction cup 30 contacts the electric meter and generates a certain suction force, the infrared receiving port 10 on the surface of the verification instrument 1 can be fine-tuned. When the infrared receiving port 10 is aligned with the infrared transmitting port of the electric meter, continue to press the suction cup 30 to release the restriction of the clamping block 43 and the clamping slot 42 on the telescopic block.

[0045] A friction groove 611 is provided on the outer surface of the positioning rod 61 at a position corresponding to the positioning pin 63. The inner surface of the friction groove 611 and the end structure of the positioning pin 63 are both of rough structure design, which increases the friction force after the positioning pin 63 contacts the friction groove 611. There are six groups of flow grooves 65, which are distributed in a circular array with the center of the positioning body 32 as the origin, thereby ensuring the integrity of the positioning body 32.
