[0022] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0024] Example 1:

[0025] This embodiment provides an installation structure for a viewing window cover of an electricity meter, including an electricity meter housing 1 and a viewing window cover 2. The electricity meter housing 1 has a viewing window 11, and the viewing window cover 2 is installed on the viewing window 11. It also includes a fixing module and a snap-fit ​​component 7. The fixing module includes:

[0026] Two fixing blocks 3 are set on the visible window 11, and a connecting groove 4 is formed between the two fixing blocks 3;

[0027] Two limiting blocks 5 are set in the connecting groove 4, and a positioning groove 6 is formed between the two limiting blocks 5;

[0028] Card connector 7 includes:

[0029] The fixing part 71 is provided on the window cover 2 and is located in the positioning groove 6;

[0030] The abutting part 72 is connected to the fixing part 71 and is located in the connecting groove 4 for abutting with the limiting block 5 in the X direction.

[0031] In this technical solution, both the window cover 2 and the snap-fit ​​component 7 are made of transparent plastic. The snap-fit ​​component 7 includes a fixed part 71 and an abutment part 72 with an integral structure, and is in the shape of a "T". The fixed part 71 is integrally connected to the window cover 2 and has a certain elastic deformation tendency. When the window cover 2 is installed on the viewing window 11, the snap-fit ​​component 7 is first bent inward by moving the abutment part 72 of the snap-fit ​​component 7. Then, the window cover 2 is placed on the viewing window 11, so that the fixed part 71 of the snap-fit ​​component 7 falls into the positioning groove 6. Then, the abutment part 72 is released so that it falls into the connecting groove 4, and the abutment part 72 abuts and hooks the limiting block 5, thereby realizing the snap-fit ​​fixation of the window cover 2 on the viewing window 11.

[0032] Through the above structural design, the viewing cover 2 can be detachably installed on the viewing window 11, which is more convenient and faster than adhesive fixing. When the viewing cover 2 is scratched or damaged, it is also easy to remove and replace for maintenance, making it convenient to use.

[0033] Furthermore, the limiting block 5 is provided with an abutting slope 51. Through this structural design, the slots of the connecting grooves 4 between the snap-fit ​​piece 7 and the two fixing blocks 3 are first inserted and engaged, which provides a certain positioning effect for the installation of the window cover 2 on the viewing window 11. Then, as the snap-fit ​​piece 7 continues to be inserted, the abutting part 72 and the abutting slope 51 on the limiting block 5 come into contact, causing the end of the snap-fit ​​piece 7 to move along the abutting slope 51, thereby causing the fixing part 71 to deform and swing inward.

[0034] When the snap-fit ​​7 is fully inserted into the connecting groove 4, the abutting part 72 has moved past the limiting block 5. The abutting inclined surface 51 of the limiting block 5 no longer touches the abutting part 72, so that the fixing part 71 returns to its original state and falls into the positioning groove 6. The abutting part 72 is located in the connecting groove 4 and abuts against the limiting block 5 in the X direction, thereby realizing the snap-fit ​​fixing of the window cover 2 on the viewing window 11.

[0035] In summary, by setting the abutting inclined surface 51 on the limiting block 5, the window cover 2 can be installed and fixed on the viewing window 11 through the insertion and cooperation of the snap-fit ​​7 and the connecting groove 4, without the need for manual manipulation of the snap-fit ​​7, thus effectively improving the ease of operation.

[0036] Example 2:

[0037] This embodiment provides an installation structure for an electricity meter window cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] Furthermore, there are multiple fixing modules and snap-fit ​​pieces 7. By setting multiple sets of fixing modules on the inner wall of the viewing window 11 and corresponding snap-fit ​​pieces 7 on the viewing window cover 2, the snap-fit ​​cooperation of multiple sets of fixing modules and snap-fit ​​pieces 7 effectively enhances the installation stability of the viewing window cover 2 on the viewing window 11.

[0039] Example 3:

[0040] This embodiment provides an installation structure for an electricity meter window cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0041] Furthermore, a storage groove 12 is provided on the viewing window 11, and the viewing window cover 2 is installed in the storage groove 12. By providing the storage groove 12, the viewing window cover 2 can be installed and embedded in the electricity meter housing 1, preventing the viewing window cover 2 from protruding from the electricity meter housing 1, thereby effectively reducing the risk of impact.

[0042] Example 4:

[0043] This embodiment provides an installation structure for an electricity meter window cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] Furthermore, a sealing ring 8 is also included, which is disposed between the storage groove 12 and the viewing window cover 2. By placing the rubber sealing ring 8 in the storage groove 12, when the viewing window cover 2 is installed on the electricity meter housing 1, the viewing window cover 2 squeezes the sealing ring 8, causing the sealing ring 8, the viewing window cover 2, and the storage groove 12 to fit tightly together, thereby maintaining a seal between the viewing window cover 2 and the viewing window 11, achieving a dustproof and waterproof effect and improving safety in use.
