Description

Technical Field

[0001] The utility model relates to the technical field of electric meters, and particularly relates to a near-infrared communication protection structure for an electric meter. Background Art

[0002] Some existing electric meters have a near-infrared communication function. The product structure design requires an infrared communication device and a near-infrared communication window to be opened on the meter box. The communication windows of some products are directly exposed, which cannot prevent external illegal infrared communication and has a low safety factor. There are also those with a protection structure, but the commonly used form on the market at present is an external flip cover. The flip cover itself occupies a relatively large space. Placed on the upper cover of the product, it causes the upper cover to protrude a large space, which is not aesthetically pleasing and is not conducive to the stacking of the outer shell and the packaging and transportation of the product. Moreover, flipping requires a flipping space and is not conducive to the installation environment in a small space. In addition, the external flip cover is also easily damaged and has poor safety.

The infrared lamp 3 is arranged inside the housing 1 and is opposite to the infrared lens 2, ensuring the accuracy and efficiency of communication. In particular, the design of the infrared shielding member, including its rotating portion 4 and shielding portion 41, provides a flexible and safe communication control mechanism for the electric meter. The rotatable installation design of the rotating portion 4 allows users to operate conveniently according to actual communication needs, while the eccentrically arranged shielding portion 41 can precisely control the opening and closing state of the infrared communication window 11, effectively preventing the interference of illegal infrared signals, thereby significantly improving the security of the electric meter.

[0031] Furthermore, the rotating part 4 is provided with a seal 42, and the seal 42 abuts against the outer side wall of the housing 1.

[0032] As described above, the abutment of the seal 42 provided in the rotating part 4 against the outer side wall of the housing 1 provides an additional sealing effect, preventing external factors such as dust and moisture from interfering with infrared communication, and at the same time increasing the protection performance of the structure.

[0033] Furthermore, the material of the seal 42 is rubber.

[0034] As described above, the rubber seal 42 can provide a more effective and stable sealing effect due to its good elasticity and sealing performance. At the same time, the rubber material also has good durability and anti-aging performance, extending the service life of the product.

[0035] Furthermore, multiple anti-slip grooves 45 are provided at the edge of the rotating part 4.

[0036] As described above, the design of multiple anti-slip grooves 45 at the edge of the rotating part 4 improves the grip stability and safety during user operation, prevents operation errors caused by hand slipping, and at the same time increases the aesthetics of the rotating part 4.

[0037] Furthermore, the rotating part 4 is provided with an indication mark, and the outer side wall of the housing 1 is provided with a first identification mark and a second identification mark; when the rotating part 4 rotates to the position where the indication mark corresponds to the first identification mark, the shielding part 41 is located in the gap between the infrared lamp 3 and the infrared lens 2; when the rotating part 4 rotates to the position where the indication mark corresponds to the second identification mark, the shielding part 41 is located outside the gap between the infrared lamp 3 and the infrared lens 2.

This visual feedback mechanism simplifies the operation process and improves the user experience.

[0039] Furthermore, the materials of the indication mark, the first identification mark, and the second identification mark are all reflective materials.
