Description

Technical Field

[0001] This utility model relates to the field of water meter box technology, and in particular to a waterproof SMC water meter box. Background Technology

[0002] Meter boxes, as a key infrastructure of municipal water supply systems, are widely used in urban and rural civil buildings. Driven by the need for convenient maintenance, existing water meter boxes are generally installed outdoors. However, because the box body needs to pass through the water supply pipe, it forms a pipe-through structure, resulting in assembly gaps between the box wall and the pipe. This structural defect makes the box body prone to leakage channels under rainwater erosion, leading to accelerated corrosion of internal instruments and shortening the equipment's lifespan.

[0003] For example, Chinese utility model patent CN221992784U discloses a moisture-proof and waterproof water meter box. The water meter box is equipped with an absorbent sponge, a humidity sensor, and a handle. During use, the absorbent sponge can absorb moisture, and the handle allows for easy replacement and cleaning. This design can waterproof and prevent moisture from entering the water meter box, thus improving its service life and performance. However, the following problems still exist: the joint between the box cover and the box body relies on a flat pressing seal, which is prone to leakage due to deformation or aging; the wiring hole uses a simple rubber plug, which is not airtight and is easy to fall off. Utility Model Content

[0028] Example 1:

[0029] like Figure 1-6 As shown, a waterproof SMC water meter box includes a box body 1 and a box cover 2 disposed at the opening of the box body 1. Mounting holes 101 are provided on both sides of the box body 1. The specific structure is as follows:

[0030] like Figure 3 As shown, a first step 102 and a second step 103 are provided at the edge of the opening of the box 1. The two are distributed in a stepped manner and are connected by an inclined connecting surface 104.

[0031] The first sealing ring 3 is embedded in the first step 102, and the second sealing ring 4 is embedded in the inclined connecting surface 104.

[0032] Furthermore, grooves 105 are provided on both the first step 102 and the inclined connecting surface 104, and the first sealing ring 3 and the second sealing ring 4 are respectively disposed in the corresponding grooves 105, wherein, for example Figure 4 As shown, the cross-section of the second sealing ring 4 is T-shaped, including a sealing part 401 attached to the inclined connecting surface 104 and an embedding part 402 embedded in the groove 105.

[0033] A pressing flange 201 is provided near the edge of the lid 2. The end of the pressing flange 201 abuts against the second step 103 and is attracted by the magnetic attractant 5. The side of the pressing flange 201 is provided with a pressing slope 202 parallel to the inclined connecting surface 104.

[0034] During installation, the edge of the cover 2 is pressed against the first step 102 and sealed by the first sealing ring 3; the downward pressing slope 202 is pressed against the inclined connecting surface 104 and sealed by the second sealing ring 4; the end of the downward pressing flange 201 abuts against the second step 103 and is attracted by the magnetic attractor 5, which uses two neodymium magnets.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, the waterproof connector 6 is located at the mounting hole 101 and includes a fixing sleeve 601 and a locking cover 602. The fixing sleeve 601 is fixed at the mounting hole 101, and the locking cover 602 is screwed onto the outside of the fixing sleeve 601. A clamping ring is provided at the end of the fixing sleeve 601, and the locking cover 602 compresses the clamping ring towards the center by axial movement. Further, the clamping ring includes multiple circumferentially distributed rubber flaps 603, and the inner surface of the locking cover 602 is a conical surface; an elastic rubber ring 604 is provided at the end of the clamping ring, and the ends of the rubber flaps 603 are fixedly connected to the elastic rubber ring 604.
