Description

Technical Field

[0001] This utility model relates to the field of water meter technology, specifically to a water meter that can be quickly disassembled. Background Technology

[0002] Quick-release water meters are easy-to-install and maintain water meter devices. They employ innovative design and technology to make installation and disassembly simpler and faster. Traditional water meters typically require tools and considerable time for installation and maintenance, while quick-release water meters can accomplish these tasks with simple operations. Quick-release water meters usually use threaded connections or other convenient connection methods, allowing installers to save time and effort. A search revealed existing technology (publication number: CN222318138U), which describes "a water meter that can be quickly disassembled and assembled, comprising a water meter body and pipes. The pipes are installed on both sides of the water meter body, and the pipes include a fixed pipe and a connecting pipe. The fixed pipe is connected to the side of the water meter body, and the connecting pipe is detachably installed at the end of a fixed block. A collar is provided on the outer side of both the fixed pipe and the connecting pipe. An installation groove is provided inside the fixed pipe, and a pressing component is installed inside the installation groove. Through the setting of the pressing component, the connecting pipe is threaded to the side of the fixed pipe, and the rotating head is threaded to the end of the fixed pipe. At the same time, the baffle presses the first telescopic column and the first spring. The rebound force of the first spring makes the threaded connection tighter, effectively improving the fastening performance of the threaded connection, ensuring the reliability of the connection, reducing problems caused by loosening, and ensuring the normal use of the water meter pipe."

[0003] While existing quick-disassembly water meters achieve the effect of quick disassembly, in practical applications, the connection between the quick-disassembly structure and the pipeline is still not as stable as that of bolted or flanged connections. Secondly, during maintenance or when cleaning the filter, the water meter is usually disassembled from the pipeline as a whole, and then the internal components of the meter casing are disassembled, which is quite troublesome. In addition, when installed in a small space with poor lighting, it is difficult to see the meter. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, a water meter that can be quickly disassembled is provided to solve the problems mentioned in the background.

[0005] To achieve the above objectives, a water meter with quick disassembly is provided, comprising: a meter casing and an inner core assembly. The outer walls of both sides of the meter casing are provided with threaded tubes, and flanges are screwed to the outer ends of the threaded tubes. A meter cover is hinged to the upper end of the meter casing. The inner side of the meter cover is provided with an inner groove, and an LED bead is provided at the edge of the inner groove. The LED bead is electrically connected to a battery power source located on the outer wall of the meter casing via a microswitch and a wire. The inner core assembly is located inside the meter casing and includes a base plate. A filter screen is provided on the upper side of the base plate, and a top plate is connected to the upper end of the filter screen. An outer casing is connected to the upper end of the top plate. A measuring mechanism is provided inside the outer casing, and a stop is provided on the outer wall of the outer casing. A sleeve is provided inside the filter screen, and an impeller is provided inside the sleeve. The top end of the impeller's spindle is connected to the measuring mechanism on the upper side. A latching mechanism is provided outside the stop, and the latching mechanism includes a groove opened on the outer wall of the meter casing. A locking block and a slider are slidably connected inside the groove. The slider is connected to the outer end of the locking block, and a threaded rod is rotatably connected to the outer end of the slider.

[0006] Furthermore, the bottom of the watch case is provided with a drain plug, the inner bottom wall of the watch case is provided with a buffer pad, and the two ends of the watch case are provided with connecting pipes.

[0007] Furthermore, the inner end of the flange is provided with a tapered connecting pipe, and the connecting pipe is provided with external threads, and the connecting pipe is screwed into the threaded pipe.

[0008] Furthermore, the upper end of the watch case is provided with a limiting protrusion, and the limiting protrusion is located at the edge of the inner groove when the watch cover is closed.

[0009] Furthermore, the lower end of the watch cover is provided with a hinge block, and the lower end of the hinge block is rotatably connected to a hinge seat. A micro switch is located on the lower side of the hinge block and fixed to the outer wall of the hinge seat watch case.

[0010] Furthermore, the hinge seat includes an outer side plate, and a damping shaft is rotatably connected inside the side plate, with the damping shaft passing through and connected to the hinge block.

[0011] Furthermore, the groove is provided with an elastic element, which is located outside the slider and outside the threaded rod, while the outer end of the threaded rod is screwed through the outer wall of the watch case.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The use of flanges, connecting pipes, and threaded pipes allows for adjustment of the connection distance when connecting to pipelines, while the connection via flanges and bolts is relatively secure; the buffer pad at the bottom of the case improves the bottom protection after the inner core components are installed, and the drain plug allows for the discharge of wastewater after cleaning the inside of the case;

[0014] 2. The watch cover is opened and closed by rotating the cover and the case. When closed, it protects the internal components. When the cover is opened, the hinge block rotates and triggers a micro switch, which connects the battery power to the LED through the wire and lights up the LED. This makes it easier to read the measurement value in a small and poorly lit space.

[0015] 3. The snap-fit ​​mechanism allows the slider and locking block to move outwards when disassembling the inner core components. This causes the locking block to disengage from the stop block, and the inner core components can then be removed one by one from the top of the meter case. This facilitates the maintenance and replacement of the inner core components, as well as the cleaning of the filter screen. It also makes it easier to clean the inside of the meter case after removing the inner core components, avoiding the hassle of disassembling the entire water meter from the pipe and then removing the internal components.

[0021] Reference Figures 1 to 4As shown, this utility model provides a water meter that can be quickly disassembled, including: a meter housing 1 and an inner core assembly 2. The outer walls of both sides of the meter housing 1 are provided with threaded tubes 13, and flanges 14 are screwed to the outer ends of the threaded tubes 13. A meter cover 16 is hinged to the upper end of the meter housing 1. An inner groove 161 is provided inside the meter cover 16, and LED beads 162 are provided at the edge of the inner groove 161. The LED beads 162 are electrically connected to a battery power supply 15 provided on the outer wall of the meter housing 1 via a microswitch 165 and a wire. The inner core assembly 2 is located inside the meter housing 1 and includes a base plate 21. A filter screen 22 is provided on the upper side of the base plate 21. A top plate 23 is connected to the upper end of the filter screen 22. A housing 26 is connected to the upper end of the top plate 23. A measuring mechanism 25 is provided inside the housing 26. Meanwhile, the outer wall of the outer casing 26 is provided with a stop 27, the inner side of the filter screen 22 is provided with a sleeve 24, the sleeve 24 is provided with an impeller, the top of the impeller's spindle is connected to the upper measuring mechanism 25, the outer side of the stop 27 is provided with a buckling mechanism 18, and the buckling mechanism 18 includes a slide groove 185 opened on the outer wall of the casing 1, the slide groove 185 is slidably connected with a stop block 183 and a slider 184, the slider 184 is connected to the outer end of the stop block 183, and the outer end of the slider 184 is rotatably connected with a threaded rod 181, the slide groove 185 is provided with an elastic element 182, and the elastic element 182 is located outside the slider 184 and outside the threaded rod 181, while the outer end of the threaded rod 181 is screwed through the outer wall of the casing 1.

[0022] In this embodiment, the casing 1 and the inner core assembly 2 constitute the main structure of the quick-disassembly water meter involved in this application.

[0023] The inner core assembly 2 includes a filter screen 22, a sleeve 24, and a measuring mechanism 25, which are consistent with the internal structure and working principle of the mechanical water meter involved in the prior art. At the same time, a glass cover is provided on the upper side of the measuring mechanism 25, and a sealing ring is provided around the cover. The glass cover is fixedly connected to the inner wall of the outer casing 26.

[0024] The filter screen 22 is a cylindrical structure and is integrated with the bottom plate 21. The sleeve 24 and the internal impeller components are integrated with the upper measuring mechanism 25. A sealing ring is provided between the top plate 23 and the inner wall of the casing 1.

[0025] Specifically, the latching mechanism 18 has two sets symmetrically arranged about the watch case 1, and the latching mechanism 18 is located near the upper edge of the watch case 1.

[0026] Specifically, the elastic element 182 is a spring, and the upper end of the part of the locking block 183 located inside the watch case 1 has an inclined cross-sectional structure, so that when the inner core assembly 2 is installed, the locking block 183 is pushed outward by the downward moving stop 27, and then the locking effect is achieved under the reset action of the spring.

[0027] like Figure 1 and Figure 2In the case 1, a drain plug 11 is provided at the bottom, and a buffer pad 12 is provided on the inner bottom wall of the case 1. Connecting pipes are provided at both ends of the case 1. A tapered connecting pipe is provided on the inner end of the flange 14. The connecting pipe is threaded and screwed into the threaded pipe 13. A limiting protrusion 17 is provided at the upper end of the case 1. The limiting protrusion 17 is located at the edge of the inner groove 161 when the cover 16 is closed. A hinge block 163 is provided at the lower end of the cover 16. A hinge seat 164 is rotatably connected to the lower end of the hinge block 163. A micro switch 165 is provided on the lower side of the hinge block 163 and fixed to the outer wall of the case 1 on the hinge seat 164. The hinge seat 164 includes an outer side plate. A damping shaft is rotatably connected inside the side plate. The damping shaft is connected through the hinge block 163.

[0028] Specifically, the drain plug 11 is a plug bolt and is connected to the threaded hole at the bottom of the casing 1.

[0029] Specifically, the lamp beads 162 are LED lamp beads and are connected in series by wires. The lamp beads 162 are arranged in a ring at equal intervals in the mounting holes opened at the lower end of the cover 16, and a glass plate is provided on the outside of the mounting holes.

[0030] Specifically, the micro switch 165 is on the rotation path of the hinge block 163. When the hinge block 163 is in a horizontal state, it does not contact the micro switch 165, causing the lamp bead 162 to turn off. When the hinge block 163 is in a vertical state, it triggers the micro switch 165, causing the lamp bead 162 to be powered on and turned on.

[0031] In use, flanges, connecting pipes, and threaded pipes allow for adjustable connection distances when connecting to pipelines, while flange and bolt connections provide a more secure connection. A buffer pad at the bottom of the meter case enhances bottom protection after the internal components are installed, and a drain plug allows for the discharge of wastewater after cleaning the inside of the meter case. The rotating connection between the meter cover and the meter case enables the cover to open and close. When closed, the cover protects the internal components. When the cover is opened, the hinged block rotates, triggering a microswitch that connects the battery power to the LED bulb via a wire, illuminating the bulb and facilitating readings in confined and poorly lit spaces. A snap-fit ​​mechanism allows for easy removal of the internal components. The threaded rod rotates, moving the slider and locking block outwards, disengaging the locking block from the stop. The internal components can then be removed one by one from the top of the meter case, facilitating maintenance and replacement, cleaning of the filter, and cleaning of the inside of the meter case after removing the internal components. This avoids the hassle of disassembling the entire water meter from the pipeline and then removing the internal components.

[0032] The quick-disassembly water meter of this invention effectively solves the problems mentioned in the background technology. Based on the existing quick-disassembly water meter technology, it facilitates the disassembly, replacement and cleaning of the internal components of the water meter, while also facilitating reading in low-light environments and adjusting the installation distance between pipes.
