Technical Field
[0001] This utility model relates to the technical field of water meter connection components, specifically a water meter connection component that prevents disassembly. Background Technology
[0002] A water meter is a professional instrument used to measure and accumulate water flow. It is widely used in residential buildings and is the core equipment for water metering and billing management. Its core structure usually includes a shell, a sleeve, and an inner core. The internal components are driven by water flow to convert the flow into a readable metering value, which not only meets the needs of reasonable water resource billing but also provides data support for water management.
[0003] During the operation of the water supply system, some users dismantle water meters without authorization to circumvent normal water billing, causing disruption to the water supply order and even posing safety hazards, thus causing trouble for water supply companies. Current water meter connection structures are generally as described in the connection component for water meters disclosed in patent application number "CN202320819816.1", including a connecting pipe, an inner ring, a rubber pad, and connecting devices. The inner sides of both ends of the connecting pipe are fixedly connected to the pads; the inner ring is fixedly connected to the edge of the pad's side wall; the rubber pad is fixedly connected to the inner wall of the cavity formed by the connecting pipe, pad, and inner ring; four connecting devices are provided, and these four connecting devices are located on the outer surface of the connecting pipe. Each connecting device includes a fixing frame, an adjusting device, a rotating frame, and a curved rod. One end of the fixing frame is fixedly connected to the outer surface of the connecting pipe, one end of the adjusting device is located inside the fixing frame, the rotating frame is located at both ends of the adjusting device, and the curved rod is fixedly connected to the end of the rotating frame away from the adjusting device. Existing water meter connection components can be easily disassembled using tools, resulting in poor tamper resistance and increased management difficulty.
[0004] Therefore, this utility model proposes a water meter connection assembly that prevents disassembly, in order to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this utility model is to provide a water meter connection component that prevents disassembly, in order to solve the problem that the existing water meter has poor anti-disassembly effect and increases the management difficulty.
[0006] The technical solution adopted by this utility model to solve its technical problem is: A water meter connection assembly designed to prevent disassembly includes a water meter body, an inlet pipe connector, and an outlet pipe connector. The two ends of the water meter body are connected to the inlet pipe connector and the outlet pipe connector respectively via bolt assemblies. An anti-disassembly protective cover is provided on the outside of the water meter body. The anti-disassembly protective cover has openings on both sides that penetrate the inlet pipe connector and the outlet pipe connector. The connection ends of the anti-disassembly protective cover with the inlet pipe connector and the outlet pipe connector are provided with annular flanges. The tamper-evident protective cover is made of acrylic material. The tamper-evident protective cover includes an upper cover and a lower cover. An tamper-evident component is connected between the upper cover and the lower cover. The tamper-evident component includes an elastic buckle. The bottom of the elastic buckle is fixedly connected to the lower cover. The upper end of the elastic buckle is detachably connected to the upper cover via a first bolt body. The first bolt body is threaded to both the upper cover and the lower cover. The head of the first bolt body is provided with a non-standard drive groove, which has an irregular structure.
[0007] Furthermore, the lower cover is connected to a hook, the upper cover has a slot corresponding to the hook, the upper cover has a second bolt body vertically connected to the hook, the upper cover has a rotation groove corresponding to the second bolt body, and the head of the second bolt body is provided with a non-standard drive groove, which is an irregular structure.
[0008] Furthermore, the top of the upper cover is evenly connected with multiple positioning protrusions, and the bottom of the lower cover is correspondingly provided with multiple positioning grooves. The positioning protrusions and the positioning grooves cooperate with each other, and the ends of the positioning protrusions are rounded.
[0009] Furthermore, multiple abutment blocks are evenly connected inside the lower cover, and an elastic block is connected to the upper end of each abutment block, which abuts against the lower end of the water meter body.
[0010] Furthermore, a fragile identification element is also connected between the upper cover and the lower cover.
[0011] Furthermore, both the upper and lower covers have anti-pry flanges at their contact edges.
[0012] Furthermore, a sealing gasket and a metal anti-tamper ring are connected inside the annular flange. The sealing gasket is disposed at the connection between the annular flange and the bolt assembly, and the metal anti-tamper ring is disposed on the inner wall of the annular flange. The inner wall of the metal anti-tamper ring abuts against the outer peripheral wall of the water inlet pipe joint and the water outlet pipe joint.
[0013] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: This utility model connects the upper end of the elastic buckle to the upper cover body through the first bolt body. The first bolt body is threadedly connected to both the lower and upper covers body. The elastic buckle generates an elastic force. The non-standard drive groove at the head of the first bolt body makes it impossible to disassemble with ordinary tools. It can only be operated with special tools, which can effectively resist external prying of the protective cover. Under the protection of the protective cover, the water meter body can accurately measure water fees and ensure the normal operation of water supply.
[0014] During the docking process, the hook on the lower cover is inserted into the corresponding slot on the upper cover to achieve initial positioning. At the same time, the positioning protrusion on the top of the upper cover and the positioning groove on the bottom of the lower cover cooperate with each other. The rounded corner design at the end of the positioning protrusion facilitates precise docking and further improves the stability of the connection between the lower cover and the upper cover.
[0015] The elastic block at the upper end of the uniformly connected abutment block inside the lower cover of this utility model is in close contact with the lower end of the water meter body. The elastic block can adapt to the slight vibration of the water meter body, which can not only buffer and protect the water meter body to prevent the water meter from being damaged by vibration and affecting the metering accuracy, but also prevent the water meter from being displaced inside the protective cover, thus ensuring stable metering.
[0016] The anti-pry flange at the edge of this invention can effectively resist external prying of the protective cover, increasing the difficulty of violent disassembly.
[0017] This utility model has a fragile identification piece installed between the upper and lower covers. The fragile identification piece is attached to the connection edge between the two. When the lower cover and the upper cover are separated, the fragile identification piece will break, which can be detected and removed in time, making it easier for the water supply company to find abnormalities during subsequent inspections.
[0018] This utility model features an acrylic anti-tamper protective cover with good transparency, allowing observation of the water meter's operating status through the cover. Basic checks can be completed without disassembly, thus balancing anti-tamper protection with daily monitoring needs. Attached Figure Description

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0022] like Figure 1 As shown, a water meter connection assembly designed to prevent disassembly includes a water meter body 1, an inlet pipe connector 2, and an outlet pipe connector 3. Both ends of the water meter body 1 are connected to the inlet pipe connector 2 and the outlet pipe connector 3 respectively via bolt assemblies 4. An anti-disassembly protective cover is provided on the outside of the water meter body 1. The anti-disassembly protective cover has openings on both sides that penetrate the inlet pipe connector 2 and the outlet pipe connector 3. An annular flange 5 is provided at the connection ends of the anti-disassembly protective cover and the inlet pipe connector 2 and the outlet pipe connector 3. A sealing gasket 6 and a metal anti-disassembly ring 7 are connected inside the annular flange 5. The sealing gasket 6 is located at the connection point between the annular flange 5 and the bolt assembly 4. The metal anti-disassembly ring 7 is located on the inner wall of the annular flange 5, and its inner wall abuts against the outer peripheral walls of the inlet pipe connector 2 and the outlet pipe connector 3.
[0023] like Figure 2 and Figure 3 As shown, the anti-disassembly protective cover is made of acrylic material. The anti-disassembly protective cover includes an upper cover 8 and a lower cover 9. An anti-disassembly component is connected between the upper cover 8 and the lower cover 9. The anti-disassembly component includes an elastic buckle 10. The bottom of the elastic buckle 10 is fixedly connected to the lower cover 9. The upper end of the elastic buckle 10 is detachably connected to the upper cover 8 through a first bolt body 11. The first bolt body 11 is threaded to both the upper cover 8 and the lower cover 9. The head of the first bolt body 11 is provided with a non-standard drive groove, which is an irregular structure.
[0024] like Figure 4 and Figure 5As shown, the lower cover 9 is connected to a hook 12, and the upper cover 8 has a corresponding slot 13. A second bolt body 14 is vertically connected to the upper cover 8 corresponding to the hook 12. A rotating groove 15 is provided on the upper cover 8 corresponding to the second bolt body 14. The head of the second bolt body 14 has a non-standard drive groove with an irregular structure. Multiple positioning protrusions 16 are evenly connected to the top of the upper cover 8, and multiple positioning grooves 17 are correspondingly provided to the bottom of the lower cover 9. The positioning protrusions 16 and positioning grooves 17 cooperate with each other, and the ends of the positioning protrusions 16 have rounded corners. A fragile identification piece 20 is also connected between the upper cover 8 and the lower cover 9. Anti-pry flanges 21 are provided on the abutting edges of both the upper cover 8 and the lower cover 9. Multiple abutting blocks 18 are evenly connected inside the lower cover 9, and an elastic block 19 is connected to the upper end of each abutting block 18, abutting against the lower end of the water meter body 1.
[0025] The working process of this utility model is as follows: First, the inlet pipe connector 2 and outlet pipe connector 3 are initially fixed at both ends of the water meter body 1 using bolt assembly 4 to ensure normal connection between the water meter body 1 and the pipeline system. Then, the anti-tamper protective cover is assembled. First, the sealing gasket 6 is installed on the inner wall of the annular flange 5 so that the inner wall of the metal anti-tamper ring 7 is tightly abutted against the inlet pipe connector 2 and outlet pipe connector 3. The sealing gasket 6 enhances the sealing of the connection, while the annular flange 5 can prevent the protective cover from being pried open from the pipe joint.
[0026] Then, the lower cover 9 and the upper cover 8 of the tamper-evident protective cover are connected. During the connection process, the hook 12 on the lower cover 9 is inserted into the corresponding slot 13 on the upper cover 8 to achieve initial positioning. At the same time, the positioning protrusion 16 on the top of the upper cover 8 and the positioning groove 17 at the bottom of the lower cover 9 cooperate with each other. The rounded corner design at the end of the positioning protrusion 16 facilitates precise connection and further improves the stability of the connection between the lower cover 9 and the upper cover 8.
[0027] After the initial connection between the lower cover 9 and the upper cover 8 is completed, the upper end of the elastic clip 10 is connected to the upper cover 8 via the first bolt body 11. The first bolt body 11 is threaded to both the lower cover 9 and the upper cover 8. When the first bolt body 11 is tightened, the elastic clip 10 generates an elastic force, further reinforcing the connection between the lower cover 9 and the upper cover 8. The non-standard drive groove at the head of the first bolt body 11 makes it impossible to disassemble with ordinary tools; only special tools can be used, thus preventing disassembly. The second bolt body 14 is vertically installed on the upper cover 8 at the position corresponding to the hook 12. The second bolt body 14 passes through the rotating groove 15 on the upper cover 8, and its head also has a non-standard drive groove. Only after the second bolt body 14 is tightened can it abut against the hook 12, allowing the hook 12 to disengage from the slot 13, further increasing the difficulty of disassembling the tamper-proof protective cover. Meanwhile, a fragile identification piece 20 is installed between the upper cover 8 and the lower cover 9. The fragile identification piece 20 is attached to the connecting edge of the two. When the lower cover 9 and the upper cover 8 are separated, the fragile identification piece 20 will break, forming intuitive evidence of tampering and damage, which will facilitate the water supply company to find abnormalities during subsequent inspections.
[0028] During water supply, the elastic block 19 at the upper end of the evenly connected abutment block 18 inside the lower cover 9 tightly abuts against the lower end of the water meter body 1. The elastic block 19 can adaptively deform according to the slight vibration of the water meter body 1, which can not only buffer and protect the water meter body 1, preventing the water meter from being damaged by vibration and affecting the metering accuracy, but also prevent the water meter from shifting inside the protective cover, ensuring stable metering. The metal anti-tamper rings 7 inside the annular flanges 5 on both sides of the anti-tamper protective cover abut against the outer peripheral wall of the pipe joint. The anti-pry flanges 21 at the abutment edges of the lower cover 9 and the upper cover 8 can effectively resist external prying of the protective cover. Under the protection of the protective cover, the water meter body 1 can accurately measure water fees and ensure the normal operation of the water supply.
