Meter reading is essential during meter replacement, electricity inspections, and meter reading procedures. Traditional manual meter reading methods are inefficient and prone to errors in meter reading, data recording, and information transmission. This method not only consumes significant human resources but also leads to data lag and inaccuracies, impacting the operational efficiency of power companies and the electricity experience for users.

[0003] Against this backdrop, smart meter reading technology has emerged. Smart meter reading terminals, through wireless communication technology and automated data collection, can acquire meter data in real time, greatly improving the efficiency and accuracy of meter reading. Furthermore, when used with smart meters, they can also control the meters, significantly simplifying offline processing. However, existing smart meter reading terminals still have shortcomings in terms of portability and ease of use. Many smart terminals are large and heavy, making them difficult to carry and operate during on-site meter reading. This is especially true for meters positioned high up, where taking photos and recording data may require single-handed operation, raising the risk of the terminal slipping from the hand.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] A field meter reading and control device, such as Figure 1 As shown, the device includes a main unit 1 and protective handles 4, which are connected to both sides of the main unit 1. The protective handles 4 on both sides of the main unit 1 facilitate gripping the main unit 1 and carrying the entire meter reading device. When carrying the meter reading device, simply hold the protective handles 4, or hang the device in a certain position using the protective handles 4. In use, the protective handles 4 can be held with both hands or one hand. When using with one hand, passing the palm through the middle of the protective handles 4 prevents the meter reading device from slipping. It should be noted that in this embodiment and subsequent embodiments, the main unit 1 uses a handheld meter reading terminal from the prior art, capable of establishing a communication connection with and controlling the smart meter, such as the HE6003 handheld meter reading terminal. Therefore, the specific structure of the main unit will not be described in detail.

[0031] Connectors 3 are provided on both sides of the main unit 1, such as... Figure 1 , Figure 2 as well as Figure 3 As shown, a fixed rotating shaft is fixedly connected to the connector 3, and fixed retaining rollers 11 are fixedly connected to both sides of the fixed rotating shaft. The protective handle 4 is rotatably connected to the fixed rotating shaft. The fixed rotating shaft is designed to facilitate the rotatable connection between the protective handle 4 and the main unit 1, thereby enabling the position adjustment of the protective handle 4. The fixed retaining rollers 11 are designed to facilitate subsequent positioning of the protective handle 4.

[0032] Control levers 13 are movably inserted on both sides of the protective handle 4, such as... Figure 3 as well as Figure 4 As shown, a limit screw 10 is threaded onto the protective handle 4; one end of the control rod 13 is connected to the fixed chuck 11, and the other end abuts against the limit screw 10. The limit screw 10 is used to hold the control rod 13 against the surface of the fixed chuck 11, thereby positioning the protective handle 4.

[0033] Specifically, during normal use, the protective handle 4 is held with both hands. At this time, the main unit 1 is relatively stable and can perform operations such as data recording, control, and photo recording.

[0034] When the meter is located at a high position, if it is a smart meter, use it normally first. Establish a communication connection with the smart meter through the host 1, and perform operations such as data reading and control of the smart meter through the host 1. After completing the above operations, hold the protective handle 4 with one hand, preferably with your palm through the gap in the middle of the protective handle 4, and then raise the host 1 to take a picture for recording.

[0035] In another possible usage method, the position of the protective handle 4 is adjusted by loosening the limiting screw 10, lifting the control lever 13 upwards, and rotating the protective handle 4. After adjustment, the control lever 13 is held in place by the limiting screw 10. Adjusting the position of the protective handle 4 is to facilitate one-handed use of the main unit 1. By adjusting the angle of the protective handle 4, it is convenient to pass the palm through the gap in the middle of the protective handle 4 during use.

[0036] In another possible usage method, the protective handles 4 on both sides of the main unit 1 are rotated 90 degrees backward. In this case, the data collection and control device can be placed on the ground for use, and the device will not be affected by damp ground.

[0037] In another possible usage method, the protective handles 4 on both sides of the main unit 1 are rotated 90 degrees backward, and the main unit 1 is placed above the electricity meter using the protective handles 4. Taking photos in this position is very stable, ensuring clearer images, which is beneficial for subsequent data comparison and data entry.

[0038] In a preferred embodiment, such as Figure 1 As shown, the corners of the protective handle 4 are rounded. The rounded design increases safety during use and enhances the overall aesthetics. The rounded design effectively reduces the risk of injury to the user's hands from sharp edges. Furthermore, the rounded shape improves the user's grip experience, making the protective handle 4 more comfortable to hold and reducing fatigue during prolonged use.

[0039] In a preferred embodiment, such as Figure 5 As shown, the fixed retaining wheel 11 has several toothed grooves, which are right-angled triangular structures. The toothed grooves are designed to easily engage the control lever 13, thereby achieving precise positioning of the protective handle 4. The right-angled triangular shape of the toothed grooves provides better restraint when the control lever 13 is inserted, ensuring that the control lever 13 will not easily slip or fall off during use, thus enhancing the stability and safety of the equipment.

[0040] Further optimization, such as Figure 1 , Figure 2 as well as Figure 3As shown, mounting cylinders 8 are fixed to both sides of the protective handle 4. One side of the control rod 13 and the limiting screw 10 are located within the mounting cylinders 8. A compression spring 12 is sleeved on the outer side of the limiting screw 10. One end of the compression spring 12 is connected to the control rod 13, and the other end is connected to the mounting cylinder 8. The compression spring 12 is used to keep the control rod 13 in an inserting position, thus maintaining the stability of the protective handle 4. Through the design of the compression spring 12, combined with the right-angled triangular groove, after the limiting screw 10 is loosened, when the protective handle 4 is rotated downwards, the control rod 13 contacts the inclined surface of the groove. The inclined surface of the groove provides an axial force to the control rod 13, allowing the control rod 13 to compress the compression spring 12, thus allowing the control rod 13 to exit the current groove and enter the next groove, achieving the downward rotation of the protective handle 4. When the protective handle 4 is rotated upwards, the right-angled side of the right-angled triangular groove will block the control rod 13, preventing the protective handle 4 from rotating upwards. In one possible use case, loosening the limit screw 10 causes the protective handle 4 to rotate downwards. Adjusting the degree of downward rotation of the protective handle 4 changes the height at which the main unit 1 is lifted, allowing the main unit 1 to take photos and record information according to different usage scenarios. In one possible design, a mounting groove 6 is provided on one side of the mounting cylinder 8, and a connecting rod 9 is fixedly connected to one side of the control rod 13. The connecting rod 9 extends out of the mounting cylinder 8 through the mounting groove 6. The connecting rod 9 is used to pull the control rod 13 upwards, causing it to disengage from the toothed groove. After the control rod 13 disengages, the protective handle 4 can rotate automatically. Normally, this method of adjusting by pulling the control rod 13 is used to reset the protective handle 4. In another possible design, the two control rods 13 are connected together by the connecting rod 9. This design aims to move both control rods 13 simultaneously by pulling with a single connecting rod 9, improving the ease of use of the device. In one possible design, a release ring 5 is connected to the middle of the connecting rod 9. The release ring 5 facilitates pulling the connecting rod 9. To prevent the connecting rod 9 from obstructing the space in the middle of the protective handle 4, the connecting rod 9 is designed to be flush against the inner wall of the protective handle 4. Therefore, it can be difficult to pull the connecting rod 9. After the release ring 5 is installed, the release ring can be pulled by inserting a finger into it.

[0041] In a preferred embodiment, such as Figure 1As shown, a protective cover 2 is provided on the outside of the main unit 1. The protective cover 2 provides additional protection for the main unit 1, preventing damage caused by external environmental factors. Furthermore, the protective cover 2 can withstand dust, dirt, moisture, and other potential physical impacts, thereby extending the service life of the main unit 1 and maintaining its normal operation. Typically, the protective handles 4 on both sides also provide some protection to the main unit 1; in the event of a drop, the protective handles 4 can provide some cushioning force. Therefore, with the addition of the extra protective cover 2, the main unit 1 receives better protection.

[0042] In a preferred embodiment, such as Figure 3 as well as Figure 4 As shown, a contact head 14 is provided on the top of the control lever 13, and the top surface of the contact head 14 has a smooth structure. The smooth contact head 14 can easily contact the limit screw 10. The limit screw 10 needs to be adjusted by rotation during use. The smooth contact head 14 can reduce the frictional resistance encountered by the limit screw 10 when rotating.

[0043] In a preferred embodiment, such as Figure 1 , Figure 2 as well as Figure 3 As shown, a rotating head 7 is provided on the top of the limiting screw 10, and several anti-slip vertical grooves are provided on the outer side of the rotating head 7. The main purpose of this design is to improve the ease of operation and safety for users when adjusting the limiting screw 10. The presence of anti-slip vertical grooves can increase the friction of the rotating head 7, making it less likely for the user's fingers to slip when rotating, thereby ensuring better control over the force and direction of rotation when applying force.
