[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 - 10 shown, the pipeline water meter provided in this embodiment includes a bottom shell 13 with an inner cavity, a first sleeve 31 and a meter core assembly; an inlet end 12 and an outlet end 11 are provided on the bottom shell 13; the first sleeve 31 and the meter core assembly are both arranged in the inner cavity; internal threads are provided on the inner walls of the ends of the outlet end 11 and the inlet end 12 away from the bottom shell. Those skilled in the art can understand that for the pipeline water meter provided in this embodiment, only the outlet end 11 and the inlet end 12 need to be installed on the pipeline, and the installation is convenient and the structure is simple.

[0024] Furthermore, the first sleeve 31 includes a first ring body 314, a first bottom plate 315, and a second ring body 311; the first bottom plate 315 is fixed to the bottom of the first ring body 314; the second ring body 311 is fixed to the top of the first ring body 314; the inner diameter of the second ring body 311 is the same as that of the first ring body 314, and the outer diameter of the second ring body 311 is greater than that of the first ring body 314; multiple groups of uniformly distributed first through holes 313 are provided on the first ring body 314; a third ring body 133 is fixed inside the bottom shell 13; the third ring body 133 divides the inner cavity into an upper chamber 132 and a lower chamber 134; the water inlet 121 of the water inlet end 12 on the bottom shell 13 is located in the lower chamber 134; the water outlet 111 of the water outlet end 11 on the bottom shell 13 is located in the upper chamber 132; the bottom of the second ring body 311 abuts against the top of the third ring body 133. Those skilled in the art can understand that the water flows into the first sleeve 31 through the first through holes 313 on the first sleeve 31 after flowing in from the water inlet end 12, overflows from above the first sleeve 31, and then flows out from the water outlet end 11, forming a passage.

[0025] Furthermore, the core assembly of the meter includes a second sleeve 24, an impeller 25, and a rotating shaft 23; the second sleeve 24 is located above the first sleeve 31; the outer wall of the second sleeve 24 is closely attached to the inner wall of the bottom shell 13; a shaft hole 244 is provided at the bottom of the second sleeve 24; one end of the impeller 25 is movably connected to the top of the first bottom plate 315, and the other end passes through the shaft hole 244 and is fixed to one end of the rotating shaft 23; a gear 22 is fixed to the other end of the rotating shaft 23; the impeller 25 is arranged inside the first sleeve 31. Those skilled in the art can understand that the gear 22 at the top of the rotating shaft 23 is used to connect with the display assembly of the meter, and the display assembly is prior art and will not be elaborated here. When water flows into the first sleeve 31, it will drive the impeller 25 to rotate. As the impeller 25 rotates, the rotating shaft 23 also rotates accordingly, so that the display assembly of the meter will display the total water consumption.

[0026] Furthermore, the core assembly of the meter further includes a first washer 26 and a second washer 21; a first annular groove 243 and a second annular groove 242 are further provided at the bottom of the second sleeve 24; both the first annular groove 243 and the second annular groove 242 are coaxially arranged with the shaft hole 244; the first washer 26 is clamped in the first annular groove 243; the second washer 21 is clamped in the second annular groove 242. Those skilled in the art can understand that through the two groups of washers, it can prevent water from flowing into the second sleeve 24 through the shaft hole 244, causing water leakage of the water meter.

[0027] Furthermore, a plurality of first grooves 312 are evenly arranged at the top of the second ring body 311; both side surfaces of the first grooves 312 and the first through holes 313 are cut surfaces; the cutting directions of the first grooves 312 are opposite to those of the first through holes 313. Those skilled in the art can understand that the cut surfaces of the first grooves 312 and the first through holes 313 can play a role in guiding the flow, thereby improving the accuracy of measuring the water flow rate; the cutting directions of the first grooves 312 and the first through holes 313 are opposite, so that no matter whether the water flow enters from the water inlet end 12 or the water outlet end 11, it can ensure that the impeller 25 rotates in the same rotation direction, avoiding incorrect installation during installation and resulting in inaccurate water meter measurement.

[0028] Furthermore, a second groove 131 is arranged at the top of the bottom shell 13; a convex rib 241 is arranged on the outer wall of the second sleeve 24; the convex rib 241 is clamped in the second groove 131. Those skilled in the art can understand that after the convex rib 241 is clamped into the second groove 131, the second sleeve 24 can be prevented from rotating in the bottom shell 13.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
