Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a water meter case and a water meter which are not easy to crack. Background Art

[0002] A water meter generally includes a water meter case and an inner core. The water meter case includes a case body, a water inlet end and a water outlet end. The case body includes a cylindrical main body and a bottom cover. The water inlet end and the water outlet end are connected to the main body. The inner core is arranged in the main body. The main body and the bottom cover are stamped and formed respectively, and then the bottom cover is welded and fixed to the bottom of the main body to seal the bottom of the main body.

[0003] However, in extremely low temperature weather, the water in the main body freezes, which can easily cause the welding seam connecting the main body and the bottom cover to crack, thereby damaging the water meter and making it unable to be used normally. Utility Model Content

[0004] The present application provides a water meter case and a water meter that are not prone to cracking, which prevent the water meter case from cracking in low temperature weather.

[0005] The water meter case that is not easy to crack provided in the present application includes a case body that is integrally formed from a metal tube. The case body includes a cylindrical main body and a bottom. The bottom is arranged at one end of the main body, and the periphery of one end of the main body and the periphery of the bottom are transitioned through an R angle.

[0006] Preferably, the case body is made of steel pipe.

[0007] Preferably, the bottom portion has the same thickness as the main body portion, or the bottom portion has a thickness greater than that of the main body portion.

[0008] Preferably, the main body is cylindrical.

[0009] Preferably, a raised portion is provided on the outer surface of the bottom for allowing the case body to be placed stably.

[0010] Preferably, the raised portion is a convex ring, which is integrally formed with the bottom.

[0011] The water meter provided in the present application includes the water meter case.

[0012] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0013] The case body is processed from a metal tube, and the case body includes a main body and a bottom, and the main body and the bottom are integrally formed. In this way, there is no weld on the case body, and even if the water in the case body freezes in low temperature weather, it is not easy to cause the case body to crack, so as to ensure that the water meter can be used normally in low temperature weather.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0018] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or modules that are not clearly listed or inherent to these processes, methods, products, or devices.

[0019] like Figure 1-2As shown, the water meter case of this embodiment, which is not easy to crack, includes a case body 10, a water inlet end 20 and a water outlet end 30, which are integrally formed from a metal tube. The case body 10 includes a cylindrical main body 11 and a bottom 12. The water inlet end 20 and the water outlet end 30 are respectively connected to the two sides of the main body 11, and the bottom 12 is arranged at one end of the main body 11. The periphery of one end of the main body 11 and the periphery of the bottom 12 are transitioned through an R angle, that is, the periphery of one end of the body 11 and the periphery of the bottom 12 are connected by a transition R angle 13, and the cross-section of the transition R angle 13 is arc-shaped. The main body 11 and the bottom 12 are smoothly transitioned through the transition R angle 13. The main body 11, the transition R angle 13 and the bottom 12 are integrally formed, that is, the case body 10 is integrally formed from a metal tube.

[0020] The case body 10 is made of a steel pipe in one piece, so that the case body 10 has high strength.

[0021] The thickness of the bottom 12 is consistent with that of the main body 11 , or the thickness of the bottom 12 is greater than that of the main body 11 , so that the thickness of the bottom 12 can ensure that the bottom 12 has sufficient strength.

[0022] The main body 11 is cylindrical.

[0023] The bottom 12 is in the shape of a flat plate, and a raised portion is provided on the outer surface of the bottom 12. The raised portion enables the case body (10) to be placed stably. Specifically, the raised portion is a raised ring 121, which is coaxially arranged with the bottom 12. The raised ring 121 and the bottom 12 are integrally formed. The raised ring 121 can make the bottom 12 more stable when placed on the ground. Of course, the raised portion can also be other shapes, such as a cross shape.

[0024] The water meter of this embodiment includes the water meter case and the inner core, and the inner core is placed in the main body 11.

[0025] It should be noted that the above-mentioned sequence of the embodiments of the present application is only for description and does not represent the advantages and disadvantages of the embodiments.
