Description

Technical Field

[0001] The utility model belongs to the technical field of water meters, in particular to a water meter which is easy to install and position. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "a water meter counter", and its announcement number is "CN109489758A". This patent mainly benefits from the fact that the pressure ring can be easily put on the mounting table to achieve axial positioning and circumferential rotation by opening the pressure ring. The pressure ring is positioned by the mounting table in the axial direction and is limited radially between the inner wall of the meter cover and the mounting table. Therefore, no matter how it is rotated, it will not fall off, or in the long-term use process, even due to some irresistible external force, it will not fall off.

[0003] However, this device requires the pressure ring to be opened before it can be installed on the installation table. When the staff installs the meter cover to fix the water meter in the device, there is a possibility that excessive force may be used, resulting in accidental breaking of the pressure ring. In addition, the clamping protrusion on the pressure ring is relatively fixed, so it is necessary to apply a large force to clamp the clamping strip on the meter cover under the clamping protrusion of the pressure ring, causing the pressure ring to deform. The operation is inconvenient and there is a risk of damage. Utility Model Content

[0030] By setting up the installation mechanism 2, the staff can turn the knob 214 and use the principle of prismatic geometry of several connecting rods 26 hinged to drive the left and right blocks 27 to be stuck in the slots 210, thereby completing the fixed installation of the flow water meter core 211 fixed in the installation base 29. The simple and fast mechanical operation structure makes the device less susceptible to damage due to external factors, making it convenient for personnel to quickly install the water meter with less force, thereby improving the convenience of the device.

[0031] The adjusting mechanism 3 includes a limit assembly and an adjusting assembly. The limit assembly includes a connecting tube 31 rotatably connected to the inner wall of the watch case 1. The outer wall of the connecting tube 31 is fixedly connected to the limit ring 32. The outer wall of the limit ring 32 is rotatably connected to the inner wall of the watch case 1. The outer wall of the limit ring 32 is provided with a plurality of grooves 33. The inner wall of the watch case 1 is provided with a second slide groove 34.

[0032] By setting up the adjustment mechanism 3, the elasticity of the second spring 36 is utilized. The staff can adjust the direction of the meter case 1 by pulling the pull ring 38.

[0033] A specific application of this embodiment is as follows: the inner core 211 of a flow meter has an internal structure divided into three layers: upper, middle, and lower. The upper layer, which only contains a pointer and a dial, is visible through the glass window. In fact, the most critical part is the lower layer. Inside, there is a plastic wheel with many plastic blades on the edge of the wheel, called an "impeller". The impeller is located exactly in the rotating flow formed by the lower hole of the casing. The water flow impacts the blades around the wheel, generating torque, which causes the impeller to rotate. The wider the faucet is opened, the faster the water flow is, and the faster the impeller rotates. The shaft of the impeller extends vertically upward to the middle layer. There is a small gear on the shaft, which meshes with the "decimal number gear" to achieve the purpose of accumulating the number of revolutions. The function of the "decimal number gear" is that every time the units digit gear rotates ten times, the tens digit gear rotates one time. In other words, for every rotation of the units digit gear, the tens digit gear rotates one tenth of a time. The units digit gear is the active driver, relying on it to drive the tens digit gear. In fact, each decimal level is completed by two pairs of gears to ensure consistent rotation direction.

[0034] By setting the mounting mechanism 2, the staff shell drives the threaded rod 212 to rotate in the first sliding groove 23 on the front side by turning the knob 214, wherein the second slider 213 is threadedly connected to the threaded rod 212, so that the threaded rod 212 rotates and drives the second slider 213 to slide along the thread in the first sliding groove 23, and the second slider 213 drives the two hinged connecting rods 26 located at the front side under the first sliding groove 23 to move closer to the middle. The multiple connecting rods 26 are hinged to each other in a prismatic shape. According to the prismatic geometric principle, the front hinge end The mutually opposed rear hinged ends approach each other synchronously, and the second sliders 213 at the hinged ends of the two front connecting rods 26 slide toward the middle, which drives the first sliders 25 at one hinged end of the left and right connecting rods 26 to slide outward, so that the two first sliders 25 slide along the guide rods 24 in the left and right first chute 23, compressing the first spring 28. Then, the mounting base 29 fixed with the flow meter inner core 211 is slid into the meter case 1, and the mounting base 29 is placed on the partition 22 through the limit of the partition 22. The knob 214 is then rotated in the opposite direction in the same manner as above, driving the second slider 213 to slide forward, and the first slider 25 is driven to slide toward the center through a plurality of connecting rods 26, so that the two clamping blocks 27 are clamped in the clamping grooves 210 of the mounting base 29, thereby completing the fixed installation of the flow meter inner core 211. A plurality of clamping grooves 210 are designed on the mounting base 29, so that personnel can adjust the appropriate direction according to needs before installing the flow meter inner core 211 for convenient observation. A first spring 28 is provided to apply elastic force to the first slider 25 to prevent the knob 214 from being accidentally rotated due to external factors. The staff can rotate the knob 214 and use the principle of prismatic geometry of the hinged connection of the plurality of connecting rods 26 to drive the left and right clamping blocks 27 to be clamped in the clamping grooves 210, thereby completing the fixed installation of the flow meter inner core 211 fixed in the mounting base 29. The simple and fast mechanical operation structure makes the device less susceptible to damage due to external factors, and facilitates personnel to quickly install the water meter with less force, thereby improving the convenience of the device.

[0035] By providing the adjustment mechanism 3 and after the connecting pipe 31 is fixedly connected to the pipeline, before installing the flow meter core 211, the staff can pull the pull ring 38 to drive the limit rod 37 to disengage from the groove 33. At this time, the limit rod 37 drives the limit plate 35 to slide in the second slide groove 34 to compress the second spring 36. Then, the meter case 1 is rotated to flip around the connecting pipe 31. After adjusting the meter case 1 to a suitable orientation, the pull ring 38 is released. Under the elastic force of the second spring 36, the limit plate 35 drives the limit rod 37 to be stuck in the groove 33 of the limit ring 32 of a specific direction, fixing the direction of the meter case 1. Then, the flow meter core 211 is installed in conjunction with the installation mechanism 2, realizing the elasticity of the second spring 36. The staff can adjust the direction of the meter case 1 by pulling the pull ring 38. After the flow meter core 211 is fixed with the installation mechanism 2, even if the device is installed at different heights or angles, it is convenient for the staff to observe the data displayed on the flow meter core 211, completing the positioning adjustment process, and improving the practicality of the device.
