For fixing the position of the straight tube 2, the top of the circular tube part 21 of the straight tube 2 is provided with a threaded hole 211, the straight tube 2 is fixedly connected with the watch case 1 by utilizing the threaded hole 211 and the screw 6, on one hand, the connection between the straight tube 2 and the watch case 1 is completed, and on the other hand, the position of the straight tube 2 is determined, so that the reflector plate 4 corresponds to the reserved transducer mounting hole on the watch case 1, and the normal use is ensured.
It should be noted that, in order to prevent the screw 6 from loosening and affecting the position of the straight tube 2, two ends of the straight tube 2 are provided with fixing sleeves 5, the inner wall of the outer end of each fixing sleeve 5 is circular, the inner end of each fixing sleeve 5 is matched with the fixing plate 221, one end, close to the straight tube 2, of each fixing sleeve 5 is provided with two clamping grooves 51, and the fixing plate 221 of the straight tube 2 is inserted into each clamping groove 51; by providing the catching groove 51, the strength of the fixing portion 22 is increased, and the resistance to water flow is increased by preventing the rotation of the fixing sleeve 5.
It should be noted that, during the assembly of the water meter, in order to avoid the movement of the fixed sleeve 5, an axial force needs to be applied to the fixed sleeve, so that the outer end of the fixed sleeve 5 is retracted inside the case 1, and a plastic ring (not shown) is arranged at the outer end of the fixed sleeve 5; therefore, when the plastic ring is connected with a pipeline, the plastic ring is extruded by the outer end face of the pipeline, and the fixed sleeve 5 is further pressed, so that the movement of the fixed sleeve is avoided.
It will be appreciated that the circular arc transition between the two ends of the circular tube portion 21 and the fixing plate 221 is beneficial to reducing the pressure loss.
Because the screw 6 can generate larger acting force when being installed, a plurality of longitudinal reinforcing ribs are arranged on the periphery of the round tube part 21, and deformation and even damage during installation are avoided.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the technical scope of the present utility model, so that any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
