Description

Technical Field

[0001] This utility model belongs to the field of NB-IoT non-magnetic water meter technology, specifically, it relates to a detachable meter body component and an NB-IoT non-magnetic water meter. Background Technology

[0002] NB-IoT water meters are smart water meters that integrate NB-IoT communication technology into traditional water meters. They can remotely collect, transmit, and manage water usage data via wireless networks, eliminating the need for manual meter reading and greatly improving data accuracy and timeliness. NB-IoT non-magnetic water meters, with their advantages of low power consumption, wide coverage, and remote data transmission, are widely used in smart water management. Their meter body components, as the core structure, require regular inspection, maintenance, or replacement of internal sensors, batteries, and other parts.

[0003] The existing NB-IoT non-magnetic water meters mostly have an integrated fixed structure for the meter body components. The water meter body and the meter body components are fixed by bolts or welding, which is inconvenient to disassemble. Disassembly requires special tools and is cumbersome, increasing the workload of maintenance personnel, reducing maintenance efficiency, and making them unsuitable for use.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is a detachable meter body assembly and an NB-IoT non-magnetic water meter, including a water meter body and a meter body assembly. The water meter body is provided with multiple mounting slots, and the meter body assembly is equipped with multiple mounting parts. The number of mounting parts is the same as the number of mounting slots, and they are matched one by one. A locking part is installed in the mounting slot. The mounting parts can be locked with the locking parts by rotation, and at the same time, the rotation of the mounting parts can drive the locking parts to lock with the mounting slots.

[0006] The bottom surface of the mounting slot is coaxially provided with a storage slot, and the bottom surface of the storage slot is coaxially installed with a positioning post. The positioning post has a guide groove, and the locking element slides with the guide groove.

[0007] The mounting components include a connecting rod, which is rotatably mounted on the watch body assembly. An operating plate is mounted on the upper end of the connecting rod, and a snap-fit ​​post is mounted on the lower end of the connecting rod. A through groove is coaxially opened on the bottom surface of the snap-fit ​​post, which is adapted to the positioning post. Multiple first positioning teeth are evenly installed on the bottom surface of the snap-fit ​​post around the axis.

[0008] The locking component includes a positioning ring, which is slidably mounted on the outer circumferential surface of the positioning post and slides through the guide groove. A locking plate is rotatably mounted on the outer circumferential surface of the positioning ring. Locking grooves are evenly distributed on the upper surface of the locking plate. The number of locking grooves is the same as that of the first positioning teeth and they are matched one by one. A snap-fit ​​plate is installed in each locking groove. A return spring is provided at the bottom end of the locking plate. The return spring is mounted around the outer circumferential surface of the positioning post, and the lower end of the return spring contacts the bottom surface of the receiving groove.

[0009] Multiple second positioning teeth are evenly installed around the axis on the bottom surface of the locking plate, and multiple snap-fit ​​grooves are evenly opened around the axis on the bottom surface of the mounting groove. The number of snap-fit ​​grooves is the same as that of the second positioning teeth, and they correspond and match one by one. The length of one end of the snap-fit ​​groove is narrower than that of the other end.

[0010] The control panel has a slot.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model allows the first positioning tooth to engage with the locking groove and the second positioning tooth to engage with the locking groove by rotating the operating plate, thus firmly fixing the meter body assembly to the water meter body. When disassembly is required, simply rotate the operating plate in the opposite direction to simultaneously release the locking of the first and second positioning teeth. This ensures locking strength and simplifies the operation process, making the quick disassembly and assembly of the meter body assembly more reliable and efficient. It is especially suitable for devices that require frequent maintenance, such as NB-IoT non-magnetic water meters.

[0013] 2. This utility model utilizes a return spring to ensure that the positioning ring is at the highest position of the guide groove, and the locking plate closes the opening of the mounting groove. When the snap-fit ​​pin is inserted into the mounting groove, the snap-fit ​​pin presses down on the locking plate, causing the locking plate to move downward. The return spring gradually compresses and eventually retracts completely into the receiving groove, with the bottom surface of the locking plate contacting the bottom surface of the mounting groove. This prevents particulate sand or impurities from entering the mounting groove during disassembly or replacement of watch body components, avoiding blockage and affecting the insertion of the snap-fit ​​pin into the mounting groove, thus improving practicality.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-10 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0027] Please see Figures 1-5 As shown:

[0028] This embodiment provides a detachable meter body assembly and an NB-IoT non-magnetic water meter, including a water meter body 1 and a meter body assembly 2. The water meter body 1 is provided with multiple mounting slots 3, and the meter body assembly 2 is provided with multiple mounting parts 4. The number of mounting parts 4 is the same as the number of mounting slots 3, and they are matched one by one. A locking part 5 is installed in the mounting slot 3. The mounting part 4 can be locked with the locking part 5 by rotation. At the same time, the rotation of the mounting part 4 can drive the locking part 5 to lock with the mounting slot 3.

[0029] Insert the mounting piece 4 into the corresponding mounting slot 3 to connect the meter body assembly 2 to the water meter body 1. Then, by rotating the mounting piece 4, it will gradually engage with the locking piece 5 in the mounting slot 3. Continuing to rotate the mounting piece 4 will cause the locking piece 5 to engage with the mounting slot 3, thereby securing the meter body assembly 2 onto the water meter body 1. When disassembly is required, simply rotate the mounting piece 4 in the opposite direction to separate the meter body assembly 2 from the water meter body 1, achieving quick disassembly and reassembly, improving efficiency, and demonstrating high practicality.

[0030] like Figure 5 , Figure 6 As shown, a storage groove 6 is coaxially provided on the bottom surface of the inner cavity of the mounting groove 3. A positioning post 7 is coaxially installed on the bottom surface of the inner cavity of the storage groove 6. A guide groove 8 is provided on the positioning post 7. The locking member 5 slides with the guide groove 8 so as to lock the locking member 5 through the positioning post 7 and the guide groove 8.

[0031] like Figures 2-10 As shown, the mounting component 4 includes a connecting rod 9, which is rotatably mounted on the watch body assembly 2. An operating plate 10 is mounted on the upper end of the connecting rod 9, and a locking post 11 is mounted on the lower end of the connecting rod 9. A through groove 12 is coaxially opened on the bottom surface of the locking post 11, which is adapted to the positioning post 7. Multiple first positioning teeth 13 are evenly installed around the axis on the bottom surface of the locking post 11. The locking component 5 includes a positioning ring 14, which is slidably mounted on the outer circumferential surface of the positioning post 7 and slides through the guide groove 8 so that the positioning ring 14 can slide vertically. A locking plate 15 is rotatably mounted on the outer circumferential surface of the positioning ring 14. Locking grooves 16 are evenly opened on the upper surface of the locking plate 15. The number of locking grooves 16 is the same as the number of first positioning teeth 13, and they are adapted to each other. A locking plate 17 is installed in each locking groove 16. A return spring 18 is provided at the bottom end of the locking plate 15. The return spring 18 is installed around the outer circumferential surface of the positioning post 7, and the lower end of the return spring 18 is in contact with the bottom surface of the storage groove 6.

[0032] When the meter body assembly 2 needs to be installed on the water meter body 1, insert the snap-fit ​​pin 11 into the installation slot 3, the positioning pin 7 enters the through slot 12, and the first positioning tooth 13 will enter the corresponding locking slot 16. Then rotate the operating plate 10 to drive the connecting rod 9 and the snap-fit ​​pin 11 to rotate synchronously. The first positioning tooth 13 will follow the rotation so that it rotates in the locking slot 16, thereby engaging and fixing with the snap-fit ​​plate 17, so that the snap-fit ​​pin 11 is fixed with the locking plate 15. At this time, continue to rotate the operating plate 10 to drive the locking plate 15 to rotate as well.

[0033] When the meter body assembly 2 is not installed on the water meter body 1 and the locking pin 11 is not inserted into the installation slot 3, the return spring 18 will be in a naturally extended state, driving the positioning ring 14 to the highest position of the guide slot 8. The locking plate 15 will close the opening of the installation slot 3. This closed state can prevent particulate sand or impurities from entering the installation slot 3 and the storage slot 6, avoiding blockage inside and affecting the insertion of the locking pin 11 into the installation slot 3. When the locking pin 11 is inserted into the installation slot 3, the locking pin 11 presses down on the locking plate 15, so that the locking plate 15 moves downward. The return spring 18 is gradually compressed and finally fully retracted into the storage slot 6, and the bottom surface of the locking plate 15 contacts the bottom surface of the installation slot 3.

[0034] like Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 9 , Figure 10 As shown, multiple second positioning teeth 19 are evenly installed around the axis on the bottom surface of the locking plate 15. Multiple locking slots 20 are evenly opened around the axis on the bottom surface of the mounting groove 3. The number of locking slots 20 is the same as the number of second positioning teeth 19, and they correspond one-to-one and fit together. One end of the locking slot 20 is narrower than the other end. When the locking plate 15 is pressed by the locking post 11 to contact the bottom surface of the mounting groove 3, the second positioning teeth 19 at the lower end of the locking plate 15 will be inserted into the locking slot 20. The wide end of the locking slot 20 is wide enough to accommodate the second positioning teeth 19. When the operating plate 10 is rotated to drive the second positioning teeth 19 to be locked by the locking plate 17, and then the operating plate 10 is rotated again, the locking plate 15 and the second positioning teeth will be locked together. Rotate the operating plate 10 to move the second positioning tooth 19 from the wide end of the locking groove 20 to the narrow end of the locking groove 20, thereby firmly locking the locking plate 15 to the bottom surface of the mounting groove 3, preventing it from moving up and down. This allows the first positioning tooth 13 to engage with the locking groove 16 and the second positioning tooth 19 to engage with the locking groove 20 by rotating the operating plate 10, thus firmly fixing the meter body assembly 2 to the water meter body 1. When disassembly is required, simply rotate the operating plate 10 in the opposite direction to simultaneously release the locking of the first positioning tooth 13 and the second positioning tooth 19. This ensures locking strength and simplifies the operation process, making the quick disassembly and assembly of the meter body assembly 2 more reliable and efficient. It is especially suitable for devices that require frequent maintenance, such as NB-IoT non-magnetic water meters.

[0035] like Figure 2 , Figure 3 As shown, the control panel 10 is provided with a slot 21, which can be used with common tools such as flathead screwdrivers and wrenches. When it is necessary to lock or unlock the watch body component 2, the tool is inserted into the slot 21. With the help of the tight fit between the tool and the slot, the operator can apply the rotational torque more stably, avoid slipping when turning by hand, and facilitate operation.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
