The present invention relates to a protective container for a water meter, and more particularly, to a binding structure of the protective container for a water meter which can prevent freezing accidents while blocking the draft while simplifying the overall configuration.

According to recent data related to water meter freezing, 94,000 freezes were carried out nationwide for nine days from January 13 to 21, 2001, and between 39,000 cars nationwide from January 21 to 26, 2004. The meter appears to be frozen. In winter, the cold water in the home water meter and the freezing of the water pipes caused by the cold weather has hindered the drinking water supply, and many consumers still suffer from inconveniences every year.

As an example to solve this problem, according to the "water meter box with improved confidentiality" of the Utility Model No. 0422219, `` a through-hole of the water inlet pipe and the water discharge pipe of the water meter at the bottom of the space to accommodate the water meter An upper open enclosure formed; A water meter box seated on an open top of the enclosure, the cover including a lid to close the top of the open enclosure; On the bottom of the cover, a rubber packing having a diameter larger than the diameter of the cover is provided, and the rubber packing is forcibly inserted between the outer diameter edge of the cover and the inner diameter surface of the upper end of the cover during the process of seating and inserting the cover on the upper part of the cover. The water meter box with improved airtightness, characterized in that configured to exhibit a stable waterproof function is disclosed.

However, when the rubber packing is installed between the enclosure and the cover, if the cover is frozen while the cover is frozen, there is a high possibility of being separated or broken when the cover is opened. In addition to the rubber packing, adhesives are used, but the adhesive surface is easily dropped due to moisture due to condensation, and airtightness is not maintained.

Accordingly, an object of the present invention is to provide a binding structure of a water tank protective container which can easily prevent the freezing accident even in a cold season by blocking the flow path of the draft easily while simplifying the overall configuration.

In order to achieve the above object, the present invention provides a protective container for wrapping and receiving a water meter: a box-shaped body having an open top; A band coupled to closely wrap the outer circumferential surface of the main body and having a plurality of threaded protrusions on an outer surface thereof; And a cover coupled in close contact with the protrusion of the band to seal the open surface of the main body.

As another feature of the present invention, the main body may further include a stepped recess formed on the outer peripheral surface of the open surface to a certain depth.

As another feature of the present invention, the band may further include a fusion unit for joining the divided surface to bind to the outer peripheral surface of the open surface of the body to promote the bonding force.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the overall protection box according to the present invention, Figure 2 is a perspective view showing the separation of the protection box according to the present invention, Figure 3a is a cross-sectional view showing the main portion coupling state of the protective cylinder cut A-A 'of FIG. 3B is a cross-sectional view showing the main part exploded state of FIG. 3A.

The present invention relates to a protective container for wrapping and receiving a water meter. If most of the domestic water meters are exposed to weather at minus 9 degrees for more than 2 hours, freezing accidents occur, which causes the inconvenience of residents and economic loss due to leakage. The present invention focuses on recognizing that the main cause of freezing waves in a protective container buried in a ground or a building is a poor airtightness and improves it.

According to the present invention, a box-shaped body 10 having an open top is used. The main body 10 is molded from a resin having heat insulation as in the prior art, but the bottom portion located in the ground may relax design values such as thickness, material, and the like as compared with other portions. Even in 12m underground, the temperature is uniformly maintained at 23 ° C throughout the year, so in case of underground reclamation, freezing hazards can be alleviated by the effects of geothermal heat.

In addition, according to the present invention, the band 20 having a plurality of threaded protrusions 25 on its outer surface is coupled to be closely wrapped on the open surface of the main body 10. Band 20 is also made of a resin and is formed in a band shape having three sides of the U-shaped cross section so as to surround the open surface of the body 10. The thickness of the three surfaces of the band 20 may be set slightly different from each other. In this case, the thickness of the outer surface portion in contact with the cover 30 to be described later in the band 20 may be the thickest to improve wear resistance.

The protrusions 25 of the band 20 are formed in a plurality of layers parallel to the outer surface portion of the band 20 in a threaded shape. Forming the protrusions 25 in the form of multilayer threads is intended to improve airtightness. The cross section of the protrusion 25 should be in the form of a triangle, but the outer end is appropriately rounded. In the figure, the protrusions 25 are arranged in three layers, but an arrangement of 2-5 layers can be selected. The larger the number of the arranged layers of the protrusions 25, the better the airtightness, but are somewhat disadvantageous in terms of formability.

That is, the protrusions 25 perform a function of blocking intrusion of draft wind, which is the main cause of freezing waves, in multiple stages. For the more effective blocking effect, the outermost of the plurality of protrusions 25 may be formed higher and thicker. The space formed between adjacent protrusions 25 also has the function of thermal insulation.

At this time, the band 20 may be further provided with a fusion unit 22 for joining the divided surface in order to bind to the outer peripheral surface of the open surface of the main body 10 to promote the bonding force. The band 20 may be formed in a one-piece form, but the workability is easy to form, but may be formed in a split form in consideration of adjusting as necessary in the field. As the constitution of the fusion unit 22, a heat fusion method, a vinyl fusion method, or an adhesive method may be selected. The fusion unit 22 may be used to bond the divided surface of the band 20, but is not limited thereto, and may perform a function of binding the body 10 and the band 20.

In addition, according to the present invention, the cover 30 is in close contact with the protrusions 25 of the band 20 so as to seal the open surface of the main body 10 and is coupled. The cover 30, together with the main body 10, uses a material having excellent heat insulation as one of the main parts of the water meter protection container.

In addition, the main body 10 may form a space by using a double member and prevent heat transfer by adding a separate heat insulator. In the case of the cover 30, it is also possible to form a space in a similar manner and to block the heat emitted to the ground surface by inserting a filler such as sawdust.

As a modification of the present invention, the main body 10 may further include a step 15 formed by being recessed to a predetermined depth on the outer circumferential surface of the open surface. By binding the band 20 with the step 15 on the main body 10, there is no change in the assembly method of the cover 30. If the depth of the step 15 is sufficiently increased, the moldability and strength are slightly weakened, but the cover 30 does not protrude from the outer circumferential surface of the main body 10, so the appearance is beautiful and the airtightness is also advantageous.

Meanwhile, although not shown in the drawing, a device capable of recovering underground heat without power may be added to the inside of the main body 10 of the water meter protection container. That is, the function of raising the temperature by introducing the geothermal heat into the body 10 is performed.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.

The binding structure of the protective container for water meter according to the above configuration and action has the effect of preventing freezing accident even in cold weather because the flow path of the draft is easily blocked while simplifying the overall configuration.
