Description

Technical Field

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

[0002] A meter box is a specialized enclosure structure used to protect the water meter itself, connecting pipes, and related accessories. It is widely used in residential, commercial buildings, and municipal water supply scenarios, and is usually installed in public areas, either outdoors or indoors.

[0003] In existing technologies, there are various types of water meter boxes that can be installed indoors or outdoors to provide physical protection for water meters, prevent water meters from being damaged by external environmental factors, and protect water meters and accessories from malfunctions caused by human damage or accidental contact, ensuring the normal operation of water meters and water consumption. However, when water meter boxes are used outdoors in winter, they may lack antifreeze structures, resulting in direct heat exchange between the inside of the box and the low-temperature external environment. Cold air from the outside can easily penetrate into the inside through the metal connectors, causing the temperature of the water meter body and pipes to drop continuously, which can lead to malfunctions such as cracked water pipes and frozen water meter glass.

Example

[0021] like Figures 1-5As shown, this utility model provides a technical solution: an antifreeze water meter box, including an antifreeze mechanism 1, an auxiliary mechanism 2 provided on the inner surface of the antifreeze mechanism 1, the antifreeze mechanism 1 including a water meter box body 11, an inner frame 12 provided on the inner surface of the water meter box body 11, the inner surface of the water meter box being fixedly connected to one end of the inner frame 12, a sleeve frame 14 provided on the outer side of the other end of the inner frame 12, the outer side of the other end of the inner frame 12 fitting and contacting the inner surface of one end of the sleeve frame 14, and the inner wall of the sleeve frame 14 being provided with heat insulation. The inner wall of the first insulation layer 16 and the inner side of the frame 14 are fixedly connected. A fitting frame 15 is provided on the outer side of the first insulation layer 16, and the outer side of the first insulation layer 16 is fixedly connected to the inner side of the fitting frame 15. One end of the fitting frame 15 is fixedly connected to the inner wall of the frame 14. A heat-absorbing layer 114 is provided on the outer side of the water meter box body 11, and the outer side of the water meter box is fixedly connected to the inner side of the heat-absorbing layer 114. A third insulation layer 111 is provided on the inner surface of the water meter box body 11, and the inner surface of the water meter box is fixedly connected to the inner side of the heat-absorbing layer 114. The outer side of the third insulation layer 111 is fixedly connected. A side plate 13 is provided on one side of the inner frame 12, and one end of the side plate 13 is fixedly connected to one side of the inner frame 12. A sleeve 19 is provided on the other end of the side plate 13, and one side of the sleeve 19 is fixedly connected to the other end of the side plate 13. A second insulation layer 110 is provided on the inner surface of the sleeve 19, and the inner surface of the sleeve 19 is fixedly connected to the outer side of the second insulation layer 110. A connecting pipe 112 is provided on the inner side of the second insulation layer 110, and the inner side of the second insulation layer 110 is connected to the connecting pipe 112. The outer side of the pipe 112 is in contact with the water meter body 113 at one end of the connecting pipe 112. The connecting pipe 112 is fixedly connected to the connecting end of the water meter body 113. A positioning plate 18 is provided on the top side of one end of the side plate 13. The top side of one end of the side plate 13 is fixedly connected to one end of the positioning plate 18. The other end of the positioning plate 18 is fitted and snapped into the inner wall of one end of the sleeve frame 14. One side of the sleeve 19 is fixedly connected to one end of the side plate 13. The outer side of one end of the side plate 13 is slidably in contact with the inner wall of the sleeve frame 14.

[0022] In this embodiment, when the antifreeze water meter box is in use, the water meter body 113 is located inside the water meter box body 11, and the connecting pipe 112 connected to the water meter body 113 passes through the water meter box body 11 from the outside and then connects to the water meter body 113. Then, an inner frame 12 is installed inside the water meter box body 11. The inner frame 12 is rectangular, and a sleeve frame 14 is connected to one end of the inner frame 12 in a sleeve manner. When the sleeve frame 14 is combined with the inner frame 12, the water meter body 113 and the connecting pipe 112 will be covered between them, thus forming another space. This makes the water meter box body 11 present a double-layered structure. Through the barrier effect of the double-layered space, the direct impact of the external low temperature environment on the internal water meter body 113 and the connecting pipe 112 is reduced. A fitting frame 15 is designed on the outer side of the middle part of the sleeve frame 14, and an insulation layer 16 is designed between the fitting frame 15 and the sleeve frame 14. The fitting frame 15 has holes 17, and the outer side of the middle part of the sleeve frame 14 has a groove. The insulation layer 16 can reduce the heat exchange between the sleeve frame 14 and the outside. The insulation layer 16 is made of glass wool, and its porous structure formed by interwoven fibers can effectively block air convection, greatly reduce the heat exchange efficiency between the sleeve frame 14 and the external environment, and ensure stable and long-lasting insulation effect. Under the action of the holes 17 and the groove of the sleeve frame 14, the insulation layer 16 can enter the holes 17 and the groove, forming an interlocking pulling force to avoid displacement. A heat-absorbing layer 114 is designed on the outside of the water meter box body 11. The heat-absorbing layer 114 is made of nano black chromium heat-absorbing film. An insulation layer 3 111 is designed on the inside of the water meter box body 11. The insulation layer 3 111 is made of the same material as the insulation layer 16. The nano black chromium coating can efficiently absorb solar radiation heat and environmental heat dissipation from the external environment. After absorbing heat, it is connected to the water meter box body 11 in a close fit. Therefore, some heat will penetrate into the interior of the water meter box body 11. At the same time, the insulation layer 3 111 on the inside can give full play to the heat insulation advantage of its porous structure, prevent the heat that penetrates into the interior from being lost to the external low-temperature environment, and lock the heat inside the water meter box. A comprehensive heat insulation barrier is built from the overall box body to the local connecting parts. A sleeve 19 is installed on the outside of the connecting pipe 112 on the water meter body 113 in a sleeve-like manner. The sleeve 19 contains a second insulation layer 110, which is in contact with the connecting pipe 112. The second insulation layer 110, the third insulation layer 111, and the first insulation layer 16 are all made of the same material. The second insulation layer 110 can directly block the heat exchange between the second insulation layer and the external low temperature environment. Combined with the physical protection of the sleeve 19, it effectively prevents the connection between the connecting pipe 112 and the water meter body 113 from freezing and cracking due to excessively low temperature. By installing a side plate 13 at one end of the inner frame 12, and fixing one end of the side plate 13 to the sleeve 19, the connection between the side plate 13 and the inner frame 12 provides a stable fixing foundation for the sleeve 19. Furthermore, a positioning plate 18 is installed on the top side of one end of the side plate 13. During the fitting process between the sleeve 14 and the inner frame 12, the positioning plate 18 can align with the holes on the sleeve 14, thereby creating a structural connection between the sleeve 14 and the inner frame 12 and increasing the stability between them. Example

[0023] like Figure 2 As shown, the auxiliary mechanism 2 includes a support plate 21, the top side of the support plate 21 is in contact with the bottom side of the sleeve frame 14, and a pull rod 22 is provided at one end of the sleeve frame 14, and one end of the sleeve frame 14 is fixedly connected to one end of the pull rod 22.

[0024] In this embodiment, a support plate 21 is installed on the inner surface of the water meter box body 11. After the sleeve frame 14 is fitted together, the support plate 21 can provide a support base from the bottom of the sleeve frame 14 by fixing it to the water meter box body 11. At the same time, it can share some of the pressure for the inner frame 12. When it is necessary to separate the sleeve frame 14 from the inner frame 12, a pull rod 22 is installed at one end of the sleeve frame 14. By holding the pull rod 22 and pulling it to one side, the force transmission effect of the pull rod 22 can be used to easily overcome the fitting resistance between the sleeve frame 14 and the inner frame 12, and achieve rapid separation of the two.

[0025] Working principle: like Figures 1-5 As shown, by combining the outer frame 14 with the inner frame 12, the water meter body 113 and the connecting pipe 112 are covered between them, thus forming another space. This makes the water meter box body 11 present a double-layered structure. Through the barrier effect of the double-layered space, a fitting frame 15 is designed on the outer side of the middle of the outer frame 14. An insulation layer 16 is designed between the fitting frame 15 and the outer frame 14. The fitting frame 15 has holes 17, and the outer side of the middle of the outer frame 14 has a groove. The insulation layer 16 can reduce the heat exchange between the outer frame 14 and the outside. The insulation layer 16 is made of glass wool, whose fibers are interwoven. The formed porous structure can effectively block air convection and significantly reduce the heat exchange efficiency between the frame 14 and the external environment. Finally, by designing a heat-absorbing layer 114 on the outside of the water meter box body 11, the nano-level black coating on the heat-absorbing layer 114 can efficiently absorb solar radiation heat and environmental heat dissipation from the external environment. After absorbing heat, since it is connected to the water meter box body 11 in a close fit, some heat will penetrate into the interior of the water meter box body 11. At the same time, the inner insulation layer 111 can give full play to the insulation advantages of its porous structure and prevent the heat that has penetrated into the interior from being lost back to the external low-temperature environment.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
