[0032] As Figures 1-5 shown, the utility model provides combined formula vertical water meter casing structure, including casing 1 and core 2, core 2 installs in casing 1, and core 2 is evenly installed with multiple guide rods 5, and evenly arranged guide rod 5 can provide stable support force when subsequent connection.

[0033] The same number of slide grooves 6 are set on the inner wall of casing 1 corresponding to the position of multiple guide rods 5, and each slide groove 6 has a vertical part 61 and a corner part 62;

[0034] The corner part 62 of each sliding groove 6 is communicated with a buckling groove 7, each guide rod 5 is slidingly connected in the corresponding sliding groove 6 and buckling groove 7, and the size of each guide rod 5 is nested with the buckling groove 7. After the guide rod 5 is slid into the buckling groove 7, the guide rod 5 can be fitted in the buckling groove 7, so as to avoid the slight shaking of the movement 2 due to the gap between the guide rod 5 and the buckling groove 7.

[0035] The support ring 3 is connected with the plurality of springs 4 in the shell 1, and the support ring 3 is in contact with the outer edge protrusion 21 of the movement 2.

[0036] As described above, when the movement 2 is installed in the shell 1, first, the guide rod 5 on the movement 2 is aligned with the sliding groove 6, and the movement 2 is inserted into the shell 1. At the same time, the outer edge protrusion 21 of the movement 2 is in contact with the support ring 3, and the support ring 3 is compressed by the movement 2, so that the support ring 3 compresses the spring 4. With the movement of the guide rod 5 in the vertical part 61 of the sliding groove 6, the support ring 3 is more compressed to the spring 4. Until the guide rod 5 moves to the bottom end of the vertical part 61 of the sliding groove 6, at this time, the movement 2 cannot be pressed into the shell 1 any more. Then, the movement 2 is rotated, so that the guide rod 5 moves from the vertical part 61 to the corner part 62. At this time, the movement 2 is rotated along the support ring 3, until the guide rod 5 moves into the buckling groove 7. At this time, the guide rod 5 is clamped by the buckling groove 7. At the same time, under the elastic potential energy of the spring 4 recovering from deformation, the support ring 3 is in contact with the outer edge protrusion 21 of the movement 2, so as to limit the position of the movement 2, and the quick installation of the movement 2 is realized.

[0037] Although the above process is relatively cumbersome, for the operator, only needs to place the movement 2 into the shell 1, and then rotate the movement 2, so as to realize the fixation of the movement 2, and the operation is very simple. At the same time, the position of the movement 2 installed is not deviated.

[0038] In the above, it is mentioned that the movement 2 is rotated along the support ring 3. In order to avoid the damage to the surface of the movement 2 caused by the friction generated in the rotating process, a plurality of balls 8 can be uniformly installed on the support ring 3, so as to reduce the friction between the support ring 3 and the movement 2.

[0039] Further, the striking plate 10 is installed in each buckling groove 7, and the hitting block 9 is installed on each guide rod 5 at the position corresponding to the striking plate 10.

[0040] Based on the above, when the guide rod 5 moves into the buckling groove 7, the hitting block 9 can hit the striking plate 10, so as to make a striking sound, to prompt the operator that the guide rod 5 is clamped into the buckling groove 7.

[0041] Moreover, the movement 2 extrudes the spring 4 through the support ring 3, so that the spring 4 is compressed and has elastic potential energy, such as Figure 5As shown, when the guide rod 5 moves into the buckle groove 7, the elastic potential energy of the compressed spring 4 is released, at this time the spring 4 drives the entire movement of the movement 2 outward by extruding the support ring 3, the guide rod 5 in the spring 4 elastic potential energy of the elastic force, will hit in the buckle groove 7, make the hitting block 9 and the striking plate 10 impact, thereby emitting sound, prompting the operator, at this time the guide rod 5 moves into the buckle groove 7, facilitate the staff to determine that the movement 2 is installed in place.

[0042] Wherein, the hitting block 9 is a conventional metal, the striking plate 10 belongs to the prior art, the main role is to emit sound when in contact with the metal block quickly.

[0043] Each sliding groove 6 is outwardly expanded at the end away from the corner portion 62, facilitating the sliding of the guide rod 5 into the sliding groove 6.

[0044] The guide rod 5 is arc-shaped on one side and square-shaped on the other side, and the width of the square-shaped portion of the guide rod 5 is consistent with the caliber of the sliding groove 6.

[0045] The arc-shaped portion of the guide rod 5 facilitates the sliding of the guide rod 5 into the sliding groove 6, and when the width of the square-shaped portion of the guide rod 5 is consistent with the caliber of the sliding groove 6, the guide rod 5 can be slid into the sliding groove 6 without inclination or angular deviation, thereby avoiding the deviation of the movement 2 in the housing 1 due to angular deviation after the movement 2 is inserted into the housing 1, thereby affecting the overall precision.

[0046] The housing 1 is provided with an identifier 11 on the outside, and the identifier 11 is provided with prompt information.

[0047] The identifier 11 is provided with a prompt of the rotating direction of the movement 2, an insertion position of the movement 2, and a final buckling position mark, and the identifier 11 can be an arrow indicating head and tail, and the head can be indicated by an arrow.

[0048] In use, the operator can correspond the position of one of the guide rods 5 of the movement 2 to the tail of the identifier 11, and then insert the movement 2 into the housing 1, so as to avoid the problem of inconvenient placement due to the operator's blind operation, and since the guide rods 5 are uniformly installed, only the position of any one of the guide rods 5 needs to be corresponded to the identifier 11, and after insertion, the movement 2 is rotated according to the direction prompted by the identifier 11, so that the guide rod 5 is rotated from the vertical portion 61 to the corner portion 62 of the sliding groove 6, facilitating the operation.

[0049] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form; any person skilled in the art can smoothly implement the present application according to the drawings shown in the specification and the above description; however, any person skilled in the art can make slight changes, modifications and equivalent changes of the present application within the scope of the technical scheme of the present application, and the equivalent embodiments of the present application are still within the protection scope of the technical scheme of the present application.
