[0024] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 The present application provides an insulated water meter box, including a box body 1, a box cover 2 is provided on the box body 1, a first insulation layer 3 is provided on the inner side of the box body 1, a first functional layer 4 is provided on the inner side of the first insulation layer 3, a second insulation layer 7 is provided on the inner side of the box cover 2, and a second functional layer 8 is provided on the inner side of the second insulation layer 7. The entire insulated water tank is formed by molding, and the groove 5 and the protrusion 6 are integrally formed in the mold. The box body 1 is made of SMC composite material with a bending strength of ≥100Mpa, a tensile strength of ≥40Mpa, and a simply supported beam impact strength of ≥35KJ / m 2 , providing high-strength protection for the insulated water tank, the No. 1 insulation layer 3 and the No. 2 insulation layer 7 are made of polypropylene EPP or polyurethane foam material with a thermal conductivity coefficient of ≤0.045W / (m:K); providing insulation function for the insulated water meter box, which can resist damage to the internal water meter caused by severe cold weather. The No. 1 functional layer 4 and the No. 2 functional layer 8 are made of PS / PP blister material, which is corrosion-resistant, impact-resistant and high-temperature-resistant, thereby extending the service life of the water meter box.

[0026] In this embodiment, the first insulation layer and the second insulation layer 7 are made of the same material, and the density of the first insulation layer 3 and the second insulation layer 7 are both ≥35 kg / m 3 When the outdoor temperature is greater than -15°C, the thickness of the first insulation layer 3 and the second insulation layer 7 are both ≥30mm, and when the outdoor temperature is less than -20°C, the thickness of the first insulation layer 3 and the second insulation layer 7 are both ≥50mm.

[0027] In this embodiment, two insulation pipes 10 are provided on the box body 1, and the outer side of the insulation pipe 10 is provided with an insulation pipe sleeve 14. The water pipe passes through the box body 1 and is protected by the insulation pipe 10 and the insulation pipe sleeve 14 to avoid being frozen. Then, the pipe hole is sealed with foam glue to ensure the sealing. The insulation pipe sleeve 14 is preferably a self-adhesive insulation pipe sleeve, which can be directly adhered to the insulation pipe 10 and protect the water pipe from being frozen together with the insulation pipe 10.

[0028] The lower sides of the No. 1 functional layer 4, the sealing groove 5, the No. 2 thermal insulation layer 7 and the No. 2 functional layer 8 are all provided with sealing grooves 5, and the upper sides of the No. 1 thermal insulation layer 3, the No. 1 functional layer 4 and the No. 2 functional layer 8 are all provided with sealing protrusions 6 that match the sealing grooves 5. The arrangement and coordination of the sealing grooves 5 and the sealing protrusions 6 can ensure the sealing of the water meter box. For example, the sealing groove 5 at the lower end of the No. 2 functional layer 8 is embedded in the interior of the sealing protrusion 6 at the upper end of the No. 1 functional layer 4. On the one hand, it can prevent dust from entering the interior of the box body 1, and on the other hand, it can prevent cold air from entering, so that the No. 1 thermal insulation layer 3 and the No. 2 thermal insulation layer 7 can play the maximum thermal insulation effect.

[0029] In this embodiment, a protrusion 11 is provided inside the box body 1. On the one hand, because 11 and 13 are both injection-molded as one piece, the recessed portion below 11 can be used as an installation hole to install the insulated water meter box on the wall. There is no need to drill additional holes during the installation process, which would cause damage to the water meter box and affect the insulation effect. In addition, a groove 13 is provided on the No. 1 insulation layer 3 to cooperate with the protrusion 11. By clamping the groove 13 on the protrusion 11, the No. 1 insulation layer 3 can be accurately positioned during installation to avoid the problem of deviation in the installation position.

[0030] In this embodiment, a lock buckle 9 is provided between the box body 1 and the box cover 2, and the box body 1 and the box cover 2 are locked by the lock buckle 9. The lock buckle 9 adopts a corrosion-resistant and aging-resistant high-strength reinforced nylon lock buckle or a 304 stainless steel buckle lock buckle, so that its service life will not be less than the service life of the box body 1.

[0031] A water divider 16 is provided inside the box body 1 and is fixed to the inside of the box body 1 via a fixing member 15 , and a hanging piece accessory can be installed on the outer wall of the box body 1 and hung on the wall for use.
