Description

Technical Field

[0001] The utility model relates to a water meter case, in particular to an intelligent water meter case capable of preventing movement rotation. Background Art

[0002] Typically, a water meter case features a retaining groove on the inner edge, into which the retaining block on the water meter movement fits. The two work together to secure the movement's angle. However, due to the limited thickness of the water meter case, the retaining groove and retaining block must also be the same thickness as the case, resulting in a weak fit. Furthermore, the high friction between the meter cover and the movement during installation can easily damage the retaining block, causing the movement to rotate with the cover. Utility Model Content

[0003] (1) Technical issues to be solved

[0004] The purpose of this utility model is to provide a smart water meter case that prevents the movement from rotating, which can improve the limiting strength between the case and the movement and prevent the cover from driving the movement to rotate. To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] (2) Technical solution

[0006] A smart water meter case that prevents movement rotation includes a case body and a threaded sleeve, wherein the threaded sleeve is welded to the top of the case body, the top of the case body shrinks inward to form a reduced diameter portion, and the top of the reduced diameter portion is provided with at least one first limiting groove; the top of the threaded sleeve extends inward to form an inner edge, the bottom of the inner edge is against the top of the reduced diameter portion, and a second limiting groove is provided on it at a position corresponding to the first limiting groove.

[0007] Furthermore, an annular groove is formed between the outer wall of the reduced diameter portion and the inner wall of the threaded sleeve, and a plurality of cleaning grooves are opened on the top of the reduced diameter portion, and the plurality of cleaning grooves connect the annular groove with the inner cavity of the case body.

[0008] Furthermore, the inner diameter of the inner edge is smaller than the inner diameter of the top of the reduced diameter portion.

[0009] Furthermore, the reduced diameter portion is completely accommodated by the threaded sleeve.

[0010] (3) Beneficial effects

[0011] Compared with the prior art, the present invention has obvious advantages and beneficial effects, specifically:

[0012] 1. By setting a reduced diameter part on the top of the case body and opening a first limiting groove on the reduced diameter part so that it corresponds to the second limiting groove on the threaded sleeve, the setting of the reduced diameter part can, on the one hand, make the inner diameter of the top of the case body match the inner diameter of the threaded sleeve, thereby ensuring that the first limiting groove and the second limiting groove are connected to form a deeper limiting groove, thereby increasing its contact area with the movement limit block and achieving the purpose of improving the limiting strength; on the other hand, the reducing diameter process can effectively increase the strength of the case body and prevent deformation.

[0013] 2. A plurality of cleaning grooves are opened on the top of the reduced diameter part. The plurality of cleaning grooves connect the annular groove with the inner cavity of the case body, thereby facilitating ultrasonic cleaning of impurities in the annular groove.

[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0026] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] See also Figure 1 and Figure 2 As shown, a smart water meter case that prevents movement rotation includes a case body 1 and a threaded sleeve 2. The threaded sleeve 2 is welded to the top of the case body 1. Specifically:

[0029] The top of the case body 1 shrinks inward to form a reduced diameter portion 11, and at least one first limiting groove 12 is opened at the top of the reduced diameter portion 11; the top of the threaded sleeve 2 extends inward to form an inner edge 21, the bottom of the inner edge 21 is against the top of the reduced diameter portion 11, and a second limiting groove 22 is opened on it at the position corresponding to the first limiting groove 12.

[0030] By providing a reducing portion 11 at the top of the case body 1, on the one hand, the inner diameter of the top of the case body 1 can be matched with the inner diameter of the threaded sleeve 2, thereby ensuring that the first limiting groove 12 and the second limiting groove 22 are connected to form a deeper limiting groove, thereby increasing its contact area with the movement limiting block and achieving the purpose of improving the limiting strength; on the other hand, the reducing process can effectively increase the strength of the case body 1 and prevent deformation.

[0031] It should be noted that, since the outer wall of the reduced diameter portion 11 is a curved surface, in order to ensure the welding strength of the threaded sleeve 2, the reduced diameter portion 11 needs to be completely accommodated by the threaded sleeve 2 so that the threaded sleeve 2 can be welded to the vertical outer wall of the case body 1. Figure 3 and Figure 4 An annular groove 3 is formed between the outer wall of the reduced diameter portion 11 and the inner wall of the threaded sleeve 2. Therefore, a plurality of cleaning grooves 13 are provided on the top of the reduced diameter portion 11. The plurality of cleaning grooves 13 connect the annular groove 3 with the inner cavity of the case body 1, thereby facilitating ultrasonic cleaning of impurities in the annular groove 3.

[0032] It is worth mentioning that the inner diameter of the inner edge 21 is smaller than the inner diameter of the top of the reduced diameter part 11 (in actual production, the inner diameters of the two generally differ by 0.5mm), so as to avoid the eccentricity between the threaded sleeve 2 and the case body 1 caused by welding and affect the assembly (if the inner diameters of the inner edge 21 and the reduced diameter part 11 are equal, the reduced diameter part 11 will partially protrude from the inner edge 21 when eccentric, resulting in obstruction during movement assembly, requiring secondary processing, which is time-consuming and labor-intensive).

[0033] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
