[0028] Example 1:

[0029] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides an energy meter with an infrared window protection structure, including an energy meter body 1, a protective shell 2 inserted into the inner wall of the energy meter body 1, a cable tray 3 installed on the inner wall of the energy meter body 1, and a protective component 4 for protecting the infrared window provided on the outer side of the energy meter body 1.

[0030] The main body 1 of the electricity meter serves as the basic framework of the entire electricity meter, providing a foundation for the installation and fixation of all other components. It supports various circuit components and structural components inside the electricity meter. The protective shell 2 is used to protect the internal circuit components, cable tray 3, and other components of the electricity meter, preventing damage to internal components from external dust, moisture, mechanical collisions, and other factors, thus extending the service life of the electricity meter.

[0034] The fixing plate 41 is provided to provide an installation base for the connecting plate 42. The connecting plate 42 can be adjusted and fixed by using screws and nuts. The protective cover 43 is fixed to the connecting plate 42 by screws to protect the infrared window and prevent it from being damaged by collisions, scratches or other damage from external objects. It can also prevent dust, moisture or other contaminants from entering the infrared window and affecting the transmission and reception of infrared signals.

[0035] Example 2:

[0036] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, two sets of buckles 8 are fixed to the inner wall of the electricity meter body 1, and card seats 9 are fixed to both sides of the cable tray 3, and the outer side of the buckle 8 is engaged with the inner wall of the card seat 9.

[0038] By engaging the buckle 8 with the bracket 9, the cable tray 3 can be quickly and securely installed on the electricity meter body 1 without the need for complicated tools, making the installation and removal of the cable tray 3 convenient.

[0039] Specifically, the inner wall of the electricity meter body 1 is provided with two sets of slots 10, and the outer side of the protective shell 2 is fixed with a snap-fit ​​block 11, and the outer side of the snap-fit ​​block 11 is slidably connected to the inner wall of the slot 10.

[0040] The snap-fit ​​block 11 slides into the slot 10, which can play a preliminary positioning role when installing the protective shell 2, so that the protective shell 2 can be accurately installed into the electricity meter body 1. At the same time, it can also limit the movement of the protective shell 2 to a certain extent, and assist the fixing bolt 13 in achieving a stable installation of the protective shell 2.

[0041] Specifically, the inner wall of the electricity meter body 1 is fixed with a mounting base 12, and the inner wall of the protective shell 2 is threaded with a fixing bolt 13, and the outer side of the fixing bolt 13 is threaded with the inner wall of the mounting base 12.

[0042] By using the mounting base 12 and fixing bolts 13 together, the protective shell 2 can be firmly fixed to the electricity meter body 1, which enhances the installation stability of the protective shell 2 and prevents the protective shell 2 from loosening or falling off during use.

[0043] Example 3:

[0044] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the inner wall of the limiting frame 6 has multiple sets of limiting grooves 14, and a spring 15 is fixed to the inner wall of the limiting groove 14. A clamping block 16 is fixed to one end of the spring 15, and a sliding rod 17 is fixed to the outer side of the clamping block 16. The outer side of the sliding rod 17 is slidably connected to the inner wall of the limiting frame 6.

[0046] A limiting groove 14 is formed on the inner wall of the limiting frame 6, and a spring 15 is fixed to the inner wall of the limiting groove 14. A clamping block 16 is connected to the limiting groove 14 through the spring 15. A sliding rod 17 is fixed to the outside of the clamping block 16 and slidably connected to the inner wall of the limiting frame 6. When the wire is placed into the limiting groove 14, the clamping block 16 clamps the wire under the action of the spring 15, so that the wire is firmly fixed in the limiting groove 14. At the same time, the sliding rod 17 can ensure the stability of the clamping block 16 during the movement process and prevent the clamping block 16 from deviating, so as to achieve precise limiting of the wire.

[0047] Specifically, the back of the electricity meter body 1 is provided with a snap-fit ​​groove 18, the inner wall of the snap-fit ​​groove 18 is slidably connected with a mounting piece 19, and the inner wall of the mounting piece 19 is provided with a mounting hole.

[0048] By setting the snap-fit ​​groove 18, the mounting piece 19 can be easily positioned. The mounting piece 19 is snapped into the snap-fit ​​strip 20 in the snap-fit ​​groove 18 by the snap-fit ​​buckle 21, so that the mounting piece 19 can be stably installed on the electricity meter body 1. Through the mounting holes opened in the inner wall of the mounting piece 19, the mounting piece 19 can be fixed to the wall or other installation positions by screws, etc., so that the electricity meter can be fixed in the required position, which facilitates the installation and use of the electricity meter.

[0049] Specifically, a snap-fit ​​strip 20 is fixed to the inner wall of the snap-fit ​​groove 18, and a snap-fit ​​buckle 21 is fixed to the inner wall of the mounting plate 19, with the outer side of the snap-fit ​​buckle 21 snapping into the outer side of the snap-fit ​​strip 20.

[0050] By engaging the snap-fit ​​groove 18 with the snap-fit ​​strip 20, the mounting piece 19 can be easily engaged with the snap-fit ​​groove 18, thereby achieving a stable installation of the mounting piece 19 on the electricity meter body 1.

[0051] Working principle: When using this infrared window protection structure, firstly, the cable tray 3 is engaged with the buckles 8 on the inner wall of the meter body 1 via the two side brackets 9, achieving quick positioning and installation. Next, the outer locking block 11 of the protective shell 2 is slid into the slot 10 on the inner wall of the meter body 1. After initial fixation, the fixing bolt 13 is threaded through the protective shell 2 and connected to the mounting base 12 on the inner wall of the meter body 1, ensuring a stable installation of the protective shell 2. The limiting bracket 6 on the inner wall of the protective shell 2, with its limiting groove 14 containing a spring 15, pushes the clamping block 16, which, in conjunction with the stable guidance of the sliding rod 17, can precisely limit the passing wires, preventing wire tangling. The wires are then positioned at the bottom of the meter body 1. The wire threading hole 5 and the second wire threading hole 7 at the bottom of the cable tray 3 facilitate the orderly introduction and exit of wires. The fixing plate 41 of the protective component 4 is fixed to the outside of the energy meter body 1. By rotating the nut on the screw, the angle of the connecting plate 42 relative to the fixing plate 41 is adjusted so that the protective cover 43 fixed on the connecting plate 42 by screws fits tightly against the outside of the infrared window, thus playing a protective role. When installing on the back of the energy meter, the snap-fit ​​buckle 21 of the mounting plate 19 is snapped into the snap-fit ​​strip 20 in the snap-fit ​​groove 18 on the back of the energy meter body 1. Then, using the mounting holes on the inner wall of the mounting plate 19, the energy meter is fixed in a suitable position by screws, etc., to complete the installation and configuration of the entire energy meter and ensure its stable operation.
