[0002] A photoelectric direct-reader for water meters is a smart water meter component integrating photoelectric sensing technology. It installs photoelectric coded sensors inside the water meter and uses technologies such as infrared, laser, and ultrasound to directly read the meter through a smart meter reading system and share data with networked devices. The photoelectric direct-reader contains many delicate electronic components and sensors that are highly sensitive to moisture and dust. If moisture or dust enters the device, it may cause short circuits, component damage, and other problems, affecting the normal operation of the device and the accuracy of readings. Therefore, a waterproof and dustproof sealed structure is required for the photoelectric direct-reader.
[0003] The waterproof and dustproof sealing structure of a water meter photoelectric direct reader is a structure specifically designed to protect the water meter photoelectric direct reader from moisture and dust. In the past, the waterproof sealing structure of water meter photoelectric direct readers was usually more complex, involving multiple sealing components and fasteners. The fit and installation of these components required high precision and skill. Therefore, the previous water meter photoelectric direct readers could not effectively ensure waterproofness while also achieving the effect of quick installation or removal of the waterproof cover as needed. Utility Model Content

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a waterproof and dustproof sealing structure for a water meter photoelectric direct reader, including a photoelectric direct reader body 1. A waterproof cover 2 is slidably connected to the upper surface of the photoelectric direct reader body 1. A connecting frame 3 is fixedly connected to the outer wall of the waterproof cover 2. A handle 4 is slidably connected to the inside of the connecting frame 3. A telescopic rod 5 is fixedly connected to the outer wall of the handle 4. A first spring 6 is slidably connected to the outer wall of the telescopic rod 5. A fixing block 7 is fixedly connected to the outer wall of the telescopic rod 5. The outer wall of the fixing block 7 is fixedly connected to the inside of the connecting frame 3. The outer wall of the first spring 6 is fixedly connected to the outer wall of the fixing block 7. A locking rod 8 is fixedly connected to the outer wall of the handle 4. A limiting groove 9 is opened inside the connecting frame 3. The outer wall of the locking rod 8 is slidably connected to the inner wall of the limiting groove 9. A connecting block 10 is slidably connected to the outer wall of the locking rod 8. A locking groove 11 is opened inside the connecting block 10. A connecting component is provided on the outer wall of the photoelectric direct reader body 1. The connecting component is used to support and fix the photoelectric direct reader body 1.
[0024] Specifically, pressing the handles 4 on both sides simultaneously causes them to slide within the connecting frame 3. The handles 4 also cause the locking rod 8 to slide within the limiting groove 9, where the limiting groove 9 limits the locking rod 8. Simultaneously, the handles 4 compress the telescopic rod 5. When the telescopic rod 5 retracts, it compresses the first spring 6. At this point, the locking rod 8 slides within the locking groove 11, thus preventing it from engaging with the connecting block 10. This allows for quick installation or removal of the waterproof cover 2. The waterproof cover 2 has excellent waterproof properties, and its tight connection with the photoelectric direct reader body 1 provides an effective dustproof seal.
[0025] Reference Figure 1 and Figure 3 The support assembly includes a connecting plate 12, the outer wall of which is fixedly connected to the outer wall of the photoelectric direct reader body 1, and the inner side of the connecting plate 12 is rotatably connected to a first connecting cylinder 13.
[0026] Specifically, the connecting plate 12 serves to support the photoelectric direct reader body 1 and to limit the first connecting cylinder 13. The photoelectric direct reader body 1 is an intelligent device component that integrates photoelectric sensing technology. It is usually used in metering instruments such as water meters to achieve non-contact digital reading. It uses a photoelectric sensor to receive light from the measured object (such as the dial of a water meter) and converts the light signal into an electrical signal. Then, through signal amplification, filtering, analog-to-digital conversion and other processing steps, the electrical signal is converted into a digital signal for subsequent display, storage and analysis.
[0027] Reference Figure 1 and Figure 3 A cylindrical block 14 is fixedly connected to the top of the first connecting cylinder 13, and a second spring 18 is fixedly connected to the inner top wall of the first connecting cylinder 13; the outer wall of the second spring 18 is slidably connected to the inner wall of the first connecting cylinder 13, and a locking block 15 is fixedly connected to the outer wall of the first connecting cylinder 13; the outer wall of the first connecting cylinder 13 is slidably connected to the second connecting cylinder 16, and the outer wall of the second spring 18 is slidably connected to the inside of the second connecting cylinder 16; a sliding groove 17 is provided inside the second connecting cylinder 16, and the outer wall of the locking block 15 is slidably connected to the inside of the sliding groove 17; a support block 19 is fixedly connected to the outer wall of the second connecting cylinder 16, and a support plate 20 is fixedly connected to the outer wall of the support block 19.
[0028] Specifically, pressing and twisting the cylindrical block 14 causes the first connecting cylinder 13 to rotate in the connecting plate 12. The cylindrical block 14 causes the first connecting cylinder 13 to slide in the second connecting cylinder 16, which in turn compresses the second spring 18. At the same time, the first connecting cylinder 13 causes the locking block 15 to slide in the sliding groove 17. The sliding groove 17 limits the locking block 15. Under the rebound of the second spring 18, the locking block 15 can be firmly locked in the sliding groove 17, achieving the effect of quickly installing the photoelectric direct reader body 1.
[0029] Reference Figure 1 and Figure 2 The outer wall of the lever 8 is slidably connected to the inner wall of the slot 11, and the outer wall of the connecting block 10 is fixedly connected to the outer wall of the photoelectric direct reader body 1.
[0030] Specifically, the slot 11 serves to limit the position of the lever 8, and the photoelectric direct reader body 1 serves to support and fix the connecting block 10.
[0031] Working principle: When this structure is needed, pressing the handles 4 on both sides simultaneously causes them to slide in the connecting frame 3. The handles 4 drive the locking rod 8 to slide in the limiting groove 9 while squeezing the telescopic rod 5. When the telescopic rod 5 retracts, it compresses the first spring 6. At this time, the locking rod 8 will slide in the locking groove 11, thereby causing the locking rod 8 to lose its engagement with the connecting block 10, thus allowing for quick installation or removal of the waterproof cover 2. Pressing and turning the cylindrical block 14 causes the first connecting cylinder 13 to rotate in the connecting plate 12. The cylindrical block 14 drives the first connecting cylinder 13 to slide in the second connecting cylinder 16 while compressing the second spring 18. At the same time, the first connecting cylinder 13 drives the locking block 15 to slide in the sliding groove 17, thus allowing for quick installation or removal of the photoelectric direct reader body 1. This structure not only achieves the effect of ensuring waterproofness but also allows for quick installation or removal of the waterproof cover 2 as needed, greatly simplifying the maintenance and replacement process of the equipment. Workers do not need to spend a lot of time or effort to disassemble and reinstall the waterproof cover 2, thus improving work efficiency. At the same time, this also enables the rapid replacement of damaged waterproof cover 2 in emergency situations, ensuring the continuous operation of the equipment. It also achieves the effect of rapid installation of the photoelectric direct reader body 1, which not only reduces installation time and installation costs, but also improves the flexibility and reliability of installation. In addition, the rapid installation design helps to reduce errors and damage risks during the installation process, thereby ensuring the stability and accuracy of the equipment.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
