Description

Technical Field

[0001] The utility model relates to the field of intelligent water meters, in particular to an intelligent water meter battery box. Background Technique

[0002] Due to the power consumption requirements during the use of intelligent water meters, batteries are often required, and the batteries are usually placed in a battery box. At present, the production of intelligent water meters mostly adopts automated assembly. However, the traditional threaded connection is inconvenient for automated assembly because it needs to be rotated to be assembled in place. Therefore, the box body and the battery cover of the battery box mostly adopt a snap-fit installation structure. Although this structure is convenient for automated assembly, once the air in the battery box expands, it will squeeze the battery cover, resulting in the battery cover being pushed out.

[0033] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Please refer to Figures 1 to 7 As shown, an intelligent water meter battery box includes a box body 1, a battery cover 2 and a snap ring 3. Specifically:

[0035] The battery cover 2 is arranged at the open end of the box body 1, and the inner wall of the open end of the box body 1 is provided with threads;

[0036] The outer surface of the battery cover 2 is provided with a card slot 21 and a sealing groove 22. The sealing groove 22 is annular and is provided with a sealing ring 4 therein;

[0037] The snap ring 3 is embedded in the slot 21. There is an opening 31 on the snap ring 3, which facilitates the expansion of the snap ring 3 during assembly so that it can be inserted into the slot 21. Moreover, several threaded blocks 32 are provided on the outer wall of the snap ring 3, and the threaded blocks 32 are adapted to the threads on the inner wall of the box body 1, enabling the snap ring 3 to be screwed into the box body 1 by threads, thereby fixing the battery cover 2 on the box body 1;

[0038] A partition block 23 is provided at the position of the slot 21 corresponding to the opening 31, thereby realizing the relative fixation of the slot 21 and the snap ring 3. Furthermore, when the battery cover 2 is rotated, the snap ring 3 can be driven to rotate, realizing the threaded connection between the battery cover 2 and the box body 1;

[0039] It is worth mentioning that, as Figure 3 and Figure 7 shown, the depth of the slot 21 is greater than the ring width of the snap ring 3, forming a first gap 5 therebetween; the reason for such a setting is that the battery cover 2 of this battery box is installed in the box body 1 by extrusion. Therefore, the threaded blocks 32 on the snap ring 3 will be squeezed by the threads on the inner wall of the box body 1. At this time, the first gap 5 can be used to enable the snap ring 3 to be squeezed inward, facilitating the installation of the snap ring 3 into the box body 1.

[0040] It can be understood that several convex blocks 24 are provided in the slot 21. These convex blocks 24 play a supporting role for the snap ring 3, thereby keeping the snap ring 3 stable in the slot 21 and ensuring the reliability of the threaded connection; and the convex blocks 24 and the threaded blocks 32 are arranged alternately, ensuring that the threaded blocks 32 can be pressed into the slot 21 when being squeezed during the installation into the box body 1 without being blocked by the convex blocks 24. Among them, convex blocks 24 are integrally provided on both sides of the partition block 23 to provide support for both ends of the snap ring 3.

[0041] Preferably, as Figure 3 shown, the width of the slot 21 is greater than the height of the snap ring 3, forming a second gap 6 therebetween; through the second gap 6, it is convenient to adjust when the threaded blocks 32 are not aligned during the extrusion installation of the battery cover 2. The specific process is as follows: when the battery cover 2 is installed in the box body 1, if the threaded blocks 32 are not aligned with the threads on the inner wall of the box body 1, that is, when the tooth tops of both sides are opposite, due to the existence of the second gap 6, the snap ring 3 can move left and right by itself during the thread extrusion, effectively avoiding the opposite of the thread tooth tops and aligning the threads.

[0042] Furthermore, as Figure 7 shown, the height of the convex block 24 plus the ring width of the snap ring 3 is equal to or less than the depth of the slot 21, enabling the convex block 24 to play a supporting role rather than fixing the snap ring 3.

[0043] It should be added that in view of the fact that the size of the snap ring 3 will change when being squeezed, the width of the partition block 23 is made smaller than the width of the opening 31, forming a third gap 7 therebetween, as Figure 7 shown, leaving space for the deformation of the snap ring 3.

[0044] To limit the position of the battery cover 2 and avoid excessive extrusion, a stop platform 11 is provided on the box body 1 at a position where the thread is far from the opening end; when the battery cover 2 is installed in place, its bottommost part abuts against the stop platform 11.

[0045] The assembly process of the present utility model is as follows:

[0046] First, expand the snap ring 3 and put it on the battery cover 2 so that the snap ring 3 is embedded in the card slot 21; then install the sealing ring 4 into the sealing groove 22; then put the battery into the box body 1; finally, install the battery cover 2 with the snap ring 3 and the sealing ring 4 into the box body 1. When installing, use the extrusion method, and utilize the elasticity of the snap ring 3 to squeeze it into the box body 1 to complete the assembly.

[0047] When assembling the present utility model, the extrusion method is adopted, which is convenient for automated assembly and greatly improves the assembly efficiency; and the fixing method uses threads. Compared with the traditional snap fasteners, it can effectively prevent the air in the battery box from expanding and squeezing out the battery cover 2. When disassembling, the screwing method can be adopted to avoid the problem of inconvenient disassembly of the snap fastener structure.

[0048] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
