[0047] Reference Figures 3 to 8According to an optional embodiment of the present invention, the controller body 2000 includes: a potting chamber 2300, which has a potting cavity 2301 inside, a circuit board 4000 and a potting layer in the potting cavity 2301, the potting layer being used to seal the circuit board 4000; a battery compartment 2400, which has a battery cavity 2401 extending in a first direction inside, the side wall of the battery compartment 2400 having a through hole (not shown in the figure), and at least one end of the battery compartment 2400 having a mounting hole 2420 along the first direction, the battery cavity 2401 communicating with the outside through the mounting hole 2420; and a battery body 5000, which is installed in the battery cavity 2401. The lead wire 5100 of 5000 is electrically connected to the circuit board 4000 through the wire hole; the limiting plate 2430 is set on the side wall of the battery compartment 2400, and the limiting plate 2430 and the inner wall of the potting compartment 2300 form an annular channel 7000. The annular channel 7000 is connected to the battery cavity 2401 through the wire hole, and along the second direction, the distance from the opening 7001 of the annular channel 7000 away from the battery cavity 2401 to the wire hole is greater than the distance from the potting layer to the wire hole. The second direction is perpendicular to the first direction. At least one battery cover 6000 is detachably connected to the battery compartment 2400. The battery cover 6000 is used to seal the mounting hole 2420.

[0048] Among them, such as Figure 1 As shown, along the first direction, a mounting hole 2420 can be provided at each end of the battery compartment 2400, and a battery cover 6000 is provided for each mounting hole 2420 to improve the convenience of assembling and disassembling the battery body 5000; for ease of understanding, the first direction can be understood as the length direction of the controller body 2000, and the second direction can be understood as the height direction of the controller body 2000, as shown. Figure 3 , Figure 6 and Figure 7 As shown.

[0049] It is easy to understand that circuit board 4000 can be a printed circuit board (PCB); and the shape of the annular channel 7000 is not limited. Annular means a circumferentially closed shape, not limited to a circle. For example... Figure 3 As shown, the limiting plate 2430 and the inner wall of the glue filling chamber 2300 form a rectangular channel, which is the annular channel 7000.

[0050] In addition, such as Figure 6As shown, when designing the structure of the controller body 2000, the battery compartment 2400 and the potting compartment 2300 can be set as an integrated structure. That is, the side wall of the battery compartment 2400 with the wire hole is connected to a part of the side wall of the potting compartment 2300. The inside of this part of the side wall is provided with a connection channel 8000. The lead wire 5100 is connected to the circuit board 4000 in the potting cavity 2301 through the wire hole and the connection channel 8000 in sequence.

[0051] It should be noted that the location of the thread hole is not easily visible; please refer to [the relevant documentation]. Figure 6 The specific location of the thread hole is determined at point A (the structure within the dotted circle), combined with... Figure 6 The positional relationship between the battery body 5000 and the connecting channel 8000 is not difficult to understand. Figure 6 The structure shown at point A is the part where the lead wire 5100 passes through the wire hole.

[0052] In this embodiment, when assembling the controller body 2000, the circuit board 4000 is installed in the potting cavity 2301. Then, the battery body 5000 is installed into the battery cavity 2401 of the battery compartment 2400 through the mounting hole 2420 in the first direction. After that, the mounting hole 2420 is sealed with the battery cover 6000. Then, the lead wire 5100 of the battery body 5000 is passed through the wire hole on the side wall of the battery compartment 2400 and pulled into the potting cavity 2301 to connect with the circuit board 4000. Then, potting is started in the potting cavity 2301 to form a potting layer until the potting layer seals the circuit board 4000 (i.e., the circuit board 4000 is isolated from the outside). After that, the potting cavity 2301 of the potting compartment 2300 is sealed with the top cover (not shown in the figure) to complete the overall assembly of the controller body 2000.

[0053] In this configuration, since glue needs to be applied to the potting cavity 2301 to seal the circuit board 4000 during assembly, the distance from the opening 7001 of the annular channel 7000 at the end opposite to the battery cavity 2401 to the wiring hole is greater than the distance from the potting layer to the wiring hole. In other words, the position of the opening 7001 of the annular channel 7000 at the end opposite to the battery cavity 2401 is higher than the potting layer. Figure 6 As shown, the annular channel 7000 isolates the wire hole from the potting cavity 2301, thus preventing the glue from entering the battery cavity 2401 through the wire hole during potting, thereby ensuring the potting sealing effect and the performance of the battery body 5000; in addition, the annular channel 7000 can also occupy the internal volume of the potting cavity 2301, thereby reducing the amount of glue to a certain extent and saving potting costs.

[0054] Please refer to the above. Figure 3 and Figure 6It is easy to understand that when the side wall of the glue potting chamber 2300 is provided with a connecting channel 8000, the lead wire 5100 is connected to the circuit board 4000 in the glue potting cavity 2301 by passing through the wire hole, the connecting channel 8000, and the annular channel 7000 in sequence.

[0055] According to an optional embodiment of the present invention, the limiting plate 2430 is provided with at least one limiting groove 2431, and the lead wire 5100 is snapped into the limiting groove 2431.

[0056] In this embodiment, after the lead wire 5100 of the battery body 5000 is pulled out of the battery cavity 2401 through the wire hole, the lead wire 5100 can be snapped into the limiting groove 2431 of the limiting plate 2430 to improve the stability of the lead wire 5100, thereby avoiding the impact of the shaking of the controller body 2000 during operation on the performance of the lead wire 5100.

[0057] Among them, since a typical battery body 5000 has two leads 5100, such as Figure 8 As shown, the depth of the limiting groove 2431 can be set to accommodate two leads 5100, that is, the two leads 5100 can be arranged along the depth direction of the limiting groove 2431 and locked together in the limiting groove 2431.

[0058] Alternatively, two limiting slots 2431 can be spaced apart on the limiting plate 2430, each limiting slot 2431 corresponding to a lead 5100 of the battery body 5000, such as... Figure 3 As shown; after the two leads 5100 of the battery body 5000 are pulled out of the battery cavity 2401 through the wire hole, the two leads 5100 can be respectively snapped into the corresponding limiting grooves 2431.

[0059] It should be noted that the depth and number of limit grooves 2431 are not limited. The above two cases are only examples, and the specific requirements should be determined according to the actual working conditions.

[0060] Figure 9 A schematic diagram of the battery cover in a split-type water meter controller provided in this embodiment of the utility model; Figure 10 A cross-sectional view of the battery cover portion of the split-type water meter controller provided in this embodiment of the utility model; Figure 11 A partial structural cross-sectional view of the battery compartment at the mounting hole in the split-type water meter controller provided in this embodiment of the utility model; Reference Figure 3 as well as Figures 9 to 11 According to an optional embodiment of the present invention, the battery cover 6000 is provided with an external thread 6100, and the inner wall of the mounting hole 2420 is provided with an internal thread 2421 that can be interference-fitted with the external thread 6100. The battery cover 6000 is detachably connected to the battery compartment 2400 by means of a threaded connection.

[0061] As mentioned above, when the battery body 5000 is installed in the battery cavity 2401 of the battery compartment 2400, the mounting hole 2420 needs to be plugged to protect and limit the battery body 5000; the specific operation is usually to plug the mounting hole 2420 through the battery cover 6000; however, if the battery cover 6000 and the mounting hole 2420 are only connected by clamping or ordinary thread connection, even if a sealing ring is arranged at the connection between the two, there is still a risk that the battery cover 6000 will loosen relative to the mounting hole 2420 due to vibration of the split water meter controller 100 during operation.

[0062] Therefore, in the embodiment, the battery cover 6000 is plugged to the mounting hole 2420 by interference fit between the internal and external threads, which is simple to operate and reliable in connection, and when the split water meter controller 100 vibrates during operation, the threaded connection can also ensure that the mounting hole 2420 is tightly plugged by the battery cover 6000, that is, the stability of the battery cover 6000 is improved on the premise of ensuring assembly efficiency.

[0063] Specifically, as shown in Figure 10 and Figure 11 , the internal thread 2421 and the external thread 6100 can be arranged as follows: the pitch of the external thread 6100 remains unchanged, and the teeth of the uppermost circle of the external thread 6100 (referred to as interference teeth 6110) have a larger cross-sectional size than the other teeth; the pitch of the internal thread 2421 remains unchanged, and the cross-sectional size of each circle of teeth of the internal thread 2421 is the same. In this way, due to the presence of the interference teeth 6110, when the battery cover 6000 is screwed into the mounting hole 2420, the internal and external threads 6100 will eventually achieve interference fit, thereby enhancing the stability of the connection between the battery cover 6000 and the mounting hole 2420.

[0064] Referring to Figure 1 and Figure 9 , according to an optional embodiment of the utility model, the controller body 2000 further comprises a cap 9000, the end face of the battery cover 6000 away from the battery cavity 2401 is an operation face 6200, the operation face 6200 is provided with an assembly groove 6211, and the cap 9000 is used for plugging the assembly groove 6211.

[0065] It is easy to understand that when the split water meter controller 100 is assembled, it is necessary to judge whether the battery body 5000 is illegally disassembled in the subsequent production and sales process.

[0066] In this embodiment, taking the assembly groove 6211 as an example, when the battery cover 6000 is installed, the battery cover 6000 is first inserted into the mounting hole 2420, and then a hexagonal wrench or the like is used to enable the battery cover 6000 to be clamped into the assembly groove 6211 of the operation face 6200, and then the battery cover 6000 is screwed; after the battery cover 6000 is assembled, the assembly groove 6211 is plugged with the sealing cap 9000, and the sealing cap and the assembly groove 6211 should be in interference fit, that is, the two cannot be disassembled, and if the battery cover 6000 is to be disassembled, the sealing cap has to be artificially destroyed and then clamped into the assembly groove 6211 by using a hexagonal wrench or the like.

[0067] Therefore, the arrangement of the present embodiment can determine whether the battery body 5000 is illegally disassembled by judging whether the sealing cap is damaged.

[0068] Figure 12 The structure of the sealing cap in the split type water meter controller provided by the present embodiment is shown in the figure; in combination with Figure 1 , Figure 9 and Figure 12 According to an optional embodiment of the present application, the operation face 6200 is provided with a mounting groove, the mounting groove has a protrusion 6210, the outer wall of the protrusion 6210 cooperates with the inner wall of the mounting groove to form an annular groove 6001, and the assembly groove 6211 is arranged on the protrusion 6210; the sealing cap 9000 is provided with a protruding rib 9100 for interference fit with the annular groove 6001, and the protruding rib 9100 is configured to be capable of being clamped into the annular groove 6001.

[0069] In this embodiment, when the battery cover 6000 is assembled, the protruding rib 9100 on the sealing cap 9000 is inserted into the annular groove 6001, so that the outer wall of the protruding rib 9100 is in interference contact with the inner wall of the mounting groove, and the inner wall of the protruding rib 9100 is in clearance fit with the outer wall of the protrusion 6210, so as to realize that the sealing cap 9000 is clamped into the annular groove 6001, thereby plugging the assembly groove 6211; a circle of chamfer 9110 can also be arranged around the outer wall of the protruding rib 9100, so as to make the sealing cap 9000 more conveniently clamped into the annular groove 6001.

[0070] This arrangement can deform the protruding rib 9100 during installation, so as to ensure that the sealing cap 9000 can be clamped into the annular groove 6001 in interference fit and plug the assembly groove 6211, and also improve the convenience of installation.

[0071] According to Figure 12 The inner bottom wall 9200 of the sealing cap 9000 can be provided with a blind hole 9210, so as to reduce the thickness of the inner bottom wall 9200, thereby facilitating the subsequent destruction of the sealing cap 9000 when the battery cover 6000 needs to be disassembled.

[0072] In addition, according to Figure 9The inside of the assembly groove 6211 can be provided with a pressure relief hole 6002 penetrating the battery cover 6000, and the pressure relief hole 6002 is used to balance the air pressure inside and outside the assembly groove 6211 when the cap 9000 blocks the assembly groove 6211, thereby further reducing the difficulty of assembly, that is, improving the convenience of assembly.

[0073] In addition, referring to Figure 1 and Figure 3 , and Figures 9 to 11 , in order to further improve the accuracy of judging whether the battery cover 6000 is disassembled, the uppermost end of the battery cover 6000 can also be provided with a boss 6300, and the external thread 6100 of the battery cover 6000 is arranged below the boss 6300; the battery compartment body 2400 is provided with a groove 2440 corresponding to the boss 6300 at the mounting hole 2420, and the internal thread 2421 of the mounting hole 2420 is arranged inside the groove 2440 (that is, compared with the groove 2440, the internal thread 2421 is located deeper in the battery cavity 2401); in this way, when the battery cover 6000 is assembled at the mounting hole 2420 by screwing, the boss 6300 will finally enter the groove 2440, that is, the side wall of the entire battery cover 6000 cannot protrude out of the mounting hole 2420, that is, after the cap 9000 blocks the assembly groove 6211, if you want to disassemble the battery cover 6000, you can only disassemble the battery cover 6000 by damaging the cap 9000, thereby improving the accuracy of judging whether the battery cover 6000 is disassembled.

[0074] As Figures 1 to 5 indicated, the utility model embodiment further provides a split type water meter controller 100, the split type water meter controller 100 includes any one of the above controller body 2000, and the controller body 2000 is equipped with at least one positioning protrusion 2100 and at least one second threaded hole 2201;The split type water meter controller 100 further includes: a pressure ring 1000, which is provided with at least one positioning groove 1100 and at least one first threaded hole 1201, and the positioning protrusion 2100 is clamped in the positioning groove 1100;And at least one screw 3000, the screw 3000 is provided in the first threaded hole 1201 and the second threaded hole 2201.

[0075] In this embodiment, when the pressure ring 1000 and the controller body 2000 are assembled, the positioning protrusion 2100 on the controller body 2000 is first aligned with the positioning groove 1100 on the pressure ring 1000, and the positioning protrusion 2100 is clamped in the positioning groove 1100, at this time the pressure ring 1000 and the controller body 2000 are preliminarily connected;Then, the screw 3000 is screwed into the first threaded hole 1201 and the second threaded hole 2201, and the screw 3000 is tightened to complete the assembly of the pressure ring 1000 and the controller body 2000.

[0076] The assembly mode can firstly realize the preliminary positioning of the compression ring 1000 and the controller body 2000 through the clamping connection of the positioning protrusion 2100 and the positioning groove 1100, and then the connection between the compression ring 1000 and the controller body 2000 is reinforced by the screw 3000; since the clamping connection of the positioning protrusion 2100 and the positioning groove 1100 can preliminarily connect the compression ring 1000 and the controller body 2000, too many screws 3000 are not needed, and the final assembly of the compression ring 1000 and the controller body 2000 can be realized through the threaded connection of a small number of screws 3000 and the above-mentioned clamping connection, so that the assembly mode can effectively reduce the assembly steps under the premise of ensuring the stability of the connection, thereby improving the assembly efficiency of the split water meter controller 100.

[0077] Among them, reference Figures 3 to 5 The first positioning boss 1200 can be arranged on the compression ring 1000, and the first threaded hole 1201 is arranged in the first positioning boss 1200; similarly, the second positioning boss 2200 is arranged on the controller body 2000, and the second threaded hole 2201 is arranged in the second positioning boss 2200; the first positioning boss 1200 and the second positioning boss 2200 can both be cylindrical structures.

[0078] In addition, reference Figure 4 and Figure 5 The positioning groove 1100 can include a first groove 1110 and a second groove 1120, and the first groove 1110 and the second groove 1120 are in communication with each other and form an included angle therebetween; similarly, the positioning protrusion 2100 also includes a first protrusion 2110 and a second protrusion 2120, and the first protrusion 2110 and the first groove 1110 are correspondingly arranged, and the second protrusion 2120 and the second groove 1120 are correspondingly arranged. In this way, when the compression ring 1000 and the controller body 2000 are preliminarily assembled (i.e., connected by clamping), the clamping relationship between the positioning protrusion 2100 and the positioning groove 1100 can be more firm, thereby further improving the reliability of assembling the compression ring 1000 and the controller body 2000.

[0079] Continuing to refer to Figures 1 to 5 According to an optional embodiment of the present application, the split water meter controller 100 includes two screws 3000; the compression ring 1000 is provided with two positioning grooves 1100 at intervals, and the compression ring 1000 is provided with two first threaded holes 1201 at intervals; the controller body 2000 is provided with two positioning protrusions 2100 at intervals, and the controller body 2000 is provided with two first threaded holes 1201 at intervals; the two positioning grooves 1100 and the two positioning protrusions 2100 are correspondingly arranged one by one, and the two first threaded holes 1201 and the two second threaded holes 2201 are correspondingly arranged one by one.

[0080] In the embodiment, two screws 3000, positioning protrusions 2100 and positioning grooves 1100 are arranged to further enhance the stability of the connection between the controller body 2000 and the compression ring 1000. During assembly, the two positioning protrusions 2100 on the controller body 2000 are first aligned with and clamped into the corresponding positioning grooves 1100 to preliminarily link the compression ring 1000 and the controller body 2000, then one screw 3000 is screwed into the corresponding first threaded hole 1201 and second threaded hole 2201, and the other screw 3000 is screwed into the other corresponding first threaded hole 1201 and second threaded hole 2201, and finally both screws 3000 are tightened to complete the assembly of the compression ring 1000 and the controller body 2000.

[0081] It is easy to understand that the number of screws 3000, positioning protrusions 2100 and positioning grooves 1100 in the embodiment is only for illustration, and the number of each component should be determined according to the specific working condition in actual working condition, and is not specifically limited.

[0082] However, it should be noted that, in order to avoid complicated assembly, the number of screws 3000 should not be too large, therefore, in the embodiment, only two screws 3000 are arranged, which will not increase the workload during assembly; and the number of positioning protrusions 2100 and positioning grooves 1100 can be more than the number of screws 3000 in principle, so that multiple positioning protrusions 2100 can be clamped into multiple positioning grooves 1100 at the same time, which will not make the assembly steps complicated; similarly, the specific number of positioning protrusions 2100 and positioning grooves 1100 should be determined according to the actual working condition.
