Description

Technical Field

[0001] This utility model relates to the field of smart meter technology, and in particular to a smart meter that can be quickly disassembled and assembled. Background Technology

[0002] Smart meters are key terminal devices used in smart grid construction to collect and measure user electricity consumption information. They mainly consist of core components such as the meter casing, main control circuit board, terminal blocks, heat dissipation structure, and communication module, and are widely used in various electricity consumption scenarios, including residential buildings and commercial and industrial sites. Smart meters need to operate stably for extended periods in complex environments such as outdoor areas or power distribution rooms. Their casing, as the core structure for equipment protection and supporting internal components, directly affects the efficiency of installation, inspection, and maintenance.

[0003] In existing technologies, smart meters typically use multiple screws to secure the casing and base. This involves drilling and tapping holes at corresponding positions on the casing and base, then tightening each screw individually to secure the casing and base. Because this connection method relies on multiple screws, each screw needs to be loosened or tightened individually using a screwdriver, making the process cumbersome, time-consuming, and significantly reducing the efficiency of meter installation and removal. This is especially problematic in confined spaces such as distribution rooms and meter boxes, where the limited space further prolongs the process and increases the risk of stripped or fallen screws. Furthermore, repeated disassembly and reassembly can cause wear on the screw holes and damage to the threads, affecting the sealing and connection accuracy between the casing and base. This negatively impacts the protection and operational stability of internal components such as circuit boards and terminals, hindering the efficiency of routine inspection and troubleshooting of smart meters. Utility Model Content

[0004] The purpose of this utility model is to provide a smart meter that can be quickly disassembled and assembled, which can solve the above-mentioned technical problems.

[0005] This utility model provides a smart meter capable of quick assembly and disassembly, comprising: a meter casing, a base, and a cover; after the meter casing and the base are connected, an installation space is formed inside, and a functional unit is provided in the installation space; a plurality of connecting arms are provided at one end of the base, and a connecting rod is provided at one end of the meter casing, the connecting rod being detachably engaged with the slots on the plurality of connecting arms; a first connecting plate is provided on both sides of the other end of the base, and a first sliding groove is provided on the first connecting plate; a second connecting plate is provided on both sides of the other end of the meter casing, and a second sliding groove is provided on the second connecting plate; sliders are provided on both sides of the cover, and the sliders are detachably placed in the first sliding groove and the second sliding groove.

[0006] As a further technical solution, mounting platforms are provided on opposite sides of the inner side of the other end of the base, and mounting holes are provided on opposite sides of the cover. After the fastener passes through the mounting holes, it connects with the mounting platform to lock the watch case and the base.

[0007] As a further technical solution, the mounting platform is provided with a guide groove and a limiting groove; a limiting plate is provided at one end of the fixing component. In the connected state, after one end of the fixing component passes through the guide groove, the limiting plate is placed in the limiting groove.

[0008] As a further technical solution, the fixing component includes: an operating head and an operating rod connected to the operating head; a limiting plate is disposed at one end of the operating rod.

[0009] As a further technical solution, the mounting hole includes a limiting hole and a connecting hole. In the connected state, the limiting hole, the connecting hole, and the guide groove are connected. After the operating rod passes through the connecting hole and the guide groove, the limiting plate is placed in the limiting groove, and the operating head is placed in the limiting hole.

[0010] As a further technical solution, it also includes: a snap-fit ​​component, which passes through a snap-fit ​​hole on the base; in the connected state, the snap-fit ​​component contacts the connecting rod.

[0011] As a further technical solution, the snap-fit ​​component includes: a snap-fit ​​arm, one end of which passes through the snap-fit ​​hole; and a snap-fit ​​connector, which is disposed at the other end of the snap-fit ​​arm and placed outside the base.

[0012] As a further technical solution, the snap-fit ​​arm is provided with a contact groove that is compatible with the connecting rod.

[0013] As a further technical solution, a sealing groove is provided on the base, and a sealing strip is provided in the sealing groove; a sealing block is provided on the case; in the connected state, the sealing block is placed in the sealing groove.

[0014] As a further technical solution, a first inclined surface is provided on the first connecting plate, and a second inclined surface is provided on the second connecting plate, with the first inclined surface and the second inclined surface being adapted to each other.

[0015] This invention's technical solution replaces the traditional multi-screw fixing method by setting a connecting rod and connecting arm interlocking structure at one end of the base and the meter casing, and a sliding quick-locking structure consisting of a first connecting plate, a sliding groove on a second connecting plate, and a slider on the cover at the other end. This effectively solves the problem of low disassembly and assembly efficiency of smart meter casings. During installation, the interlocking of the casing connecting rod and the base connecting arm enables quick positioning at one end, while the other end is locked by sliding the cover slider into the first and second sliding grooves. This eliminates the need for screwdrivers or other tools, simplifying the operation and significantly improving the efficiency of casing disassembly and assembly. In confined spaces such as power distribution rooms and meter boxes, this invention eliminates the need to align each screw hole individually, avoiding problems such as stripped screws or screws falling out, and reducing operational difficulty. Meanwhile, the combination of snap-fit ​​and sliding groove connection reduces the risk of screw hole wear and thread damage caused by repeated disassembly and assembly, ensures the connection sealing and accuracy between the meter casing and the base, enhances the protection of internal functional units, improves the operational stability of smart meters in complex environments, and provides convenience for daily inspection and fault maintenance, effectively improving the efficiency of power operation and maintenance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1-10 As shown, the present invention proposes a smart meter capable of quick assembly and disassembly, comprising:

[0033] The watch case 100, base 200, and cover 300 are connected to form an installation space. A functional unit (not shown in the figure) is installed within this space. This functional unit includes a main control circuit board, terminal blocks, a heat dissipation structure, and a communication module. Since the functional unit utilizes existing technology, this invention will not further describe it. One end of the base 200 has several connecting arms 400, and one end of the watch case 100 has a connecting rod 500. The connecting rod 500 is detachably engaged with the slots on the connecting arms 400. On the other end of the base 200, two opposing sides have a first connecting plate 601 with a first sliding groove 602. On the other end of the watch case 100, two opposing sides have a second connecting plate 701 with a second sliding groove 702. On the cover 300, two opposing sides have sliders 800, which are detachably placed within the first sliding groove 602 and the second sliding groove 702.

[0034] In practice, the connecting rod 500 on the watch case 100 is placed in the slot on the connecting arm 400, and the connecting arm 400 is engaged with the connecting rod 500, so that the first connecting plate 601 and the second connecting plate 701 are in contact. After the first connecting plate 601 and the second connecting plate 701 are in contact, the first sliding groove 602 and the second sliding groove 702 are aligned. The slider 800 on the cover 300 is placed in the second sliding groove 702, and the cover 300 is pushed to slide along the second sliding groove 702 until the slider 800 is completely placed in the first sliding groove 602. Within the second slide groove 702, the watch case 100 and the base 200 are connected. When disassembly is required, the cover 300 is operated in reverse to separate the slider 800 from the first slide groove 602 and the second slide groove 702, and to separate the connecting rod 500 from the connecting arm 400, thus completing the disassembly of the watch case 100 and the base 200. The slider 800 has a rectangular structure and slides with the first slide groove 602 and the second slide groove 702 with a gap of 0.05mm-0.2mm to ensure smooth sliding while avoiding shaking during use.

[0035] like Figures 6-8 As shown, two connecting arms 400 are arranged opposite each other inside the base 200, and two connecting blocks are arranged opposite each other on the case 100. A connecting rod 500 is threaded through the connecting blocks. When the connecting rod 500 is engaged with the connecting arm 400, the cooperative structure of the two connecting arms 400 and the two connecting blocks can ensure the stability of the connecting rod 500 after engagement. In this utility model, the slot includes an inlet and a receiving groove. The diameter of the receiving groove is equal to the diameter of the connecting rod 500. The opening size of the inlet is smaller than the diameter of the connecting rod 500. Since the connecting arm 400 is made of plastic, when the connecting rod 500 enters through the inlet, the inlet will deform after being squeezed by the connecting rod 500. When the connecting rod 500 enters the receiving groove, the squeezing force on the inlet disappears, the inlet resets, and the connecting rod 500 is limited.

[0036] In addition, an inner bevel is provided on the end of the base 200 adjacent to the connecting arm 400, and an outer bevel is provided on the end of the watch case 100 adjacent to the connecting rod 500; when the connecting rod 500 and the connecting arm 400 are engaged, the inner bevel and the outer bevel fit together to achieve a seal between the watch case 100 and the base 200.

[0037] The technical solution of this utility model is to set a connecting rod 500 and a connecting arm 400 at one end of the base 200 and the meter case 100, and a sliding quick-lock structure composed of a sliding groove on the first connecting plate 601, a second connecting plate 701, and a slider 800 on the cover 300 at the other end. This replaces the traditional multi-screw fixing method and effectively solves the problem of low disassembly and assembly efficiency of the smart meter case 100. During installation, the connecting rod 500 of the case 100 is engaged with the connecting arm 400 of the base 200 to achieve quick positioning at one end, and the other end is locked by sliding the slider 800 of the cover 300 into the first sliding groove 602 and the second sliding groove 702. No screwdriver or other tools are needed, which simplifies the operation steps and significantly improves the disassembly and assembly efficiency of the case 100. In the confined space of the power distribution room, meter box, etc., the technical solution of this utility model does not require aligning each screw hole, avoiding problems such as stripped screws and screws falling out, and reducing the difficulty of operation. Meanwhile, the combination of snap-fit ​​and sliding groove connection reduces the risk of screw hole wear and thread damage caused by repeated disassembly and assembly, ensures the connection sealing and accuracy between the meter housing 100 and the base 200, enhances the protection effect of internal functional units, improves the operational stability of smart meters in complex environments, and provides convenience for daily inspection and fault maintenance, effectively improving the efficiency of power operation and maintenance.

[0038] like Figures 4-7 As shown, mounting platforms 201 are arranged opposite each other on the inner sides of the other end of the base 200, and mounting holes 301 are arranged opposite each other on the cover 300. In the connected state, the fixing member 900 passes through the mounting hole 301 and connects with the mounting platform 201. In this utility model, when the slider 800 is placed in the first slide groove 602 and the second slide groove 702, in order to avoid displacement of the slider 800 in the first slide groove 602 and the second slide groove 702 during use, the cover 300 is limited by the fixing member 900 after being connected to the mounting platform 201, so as to ensure the stability of the cover 300 during use and further ensure the stability of the watch case 100 after being connected to the base 200.

[0039] like Figure 6 As shown, the mounting platform 201 is provided with a guide groove 211 and a limiting groove 212; one end of the fixing member 900 is provided with a limiting plate 901. In the connected state, one end of the fixing member 900 passes through the guide groove 211 and places the limiting plate 901 in the limiting groove 212; when the slider 800 is completely placed in the first sliding groove 602 and the second sliding groove 702, the fixing member 900 is inserted into the mounting hole 301. As the fixing member 900 is continuously inserted, the limiting plate 901 will pass through the guide groove 211 and be placed in the position of the limiting groove 212. Rotating the fixing member 900 will place the limiting plate 901 in the limiting groove 212, thereby achieving the engagement of the limiting plate 901 and the limiting groove 212; and the fixing member 900 limits the sealing cover 300.

[0040] Specifically, the fixing component 900 includes an operating head 902 and an operating rod 903 connected to the operating head 902; a limiting plate 901 is disposed at one end of the operating rod 903. When operating the fixing component 900, the operating head 902 is held, so that the limiting plate 901 and the operating rod 903 are simultaneously placed in the mounting hole 301. As the operating rod 903 is continuously inserted, the limiting plate 901 is placed in the limiting groove 212. The operating head 902 is rotated, and the limiting plate 901 is rotated through the operating rod 903, so that the limiting plate 901 is placed in the limiting groove 212.

[0041] like Figure 4 and Figure 5 As shown, the mounting hole 301 includes a limiting hole 311 and a connecting hole 312. In the connected state, the limiting hole 311, the connecting hole 312, and the guide groove 211 are connected. After the operating rod 903 passes through the connecting hole 312 and the guide groove 211, the limiting plate 901 is placed in the limiting groove 212, and the operating head 902 is placed in the limiting hole 311. The diameter of the operating head 902 is larger than the diameter of the operating rod 903 to ensure that the operating head 902 does not enter the connecting hole 312. Figure 9 As shown, the connecting hole 312 is a waist hole, which ensures that the operating rod 903 and the limiting plate 901 can pass through, while also restricting the insertion direction of the limiting plate 901 to avoid errors during operation and affect installation efficiency.

[0042] Of course, to further increase the stability of the watch case 100 and the base 200 after connection, this utility model provides a snap-fit ​​component 1000, which passes through the snap-fit ​​hole 202 on the base 200; in the connected state, the snap-fit ​​component 1000 contacts the connecting rod 500; as Figure 3 As shown, after the connecting rod 500 is engaged with the connecting arm 400, the engaging member 1000 is inserted into the engaging hole 202 and brought into contact with the connecting rod 500 to limit the connecting rod 500 and prevent it from detaching from the connecting arm 400. When disassembling, the engaging member 1000 needs to be pulled out of the engaging hole 202 first to release the constraint of the engaging member 100 on the connecting rod 500 before the watch case 100 and the base 200 can be disassembled.

[0043] like Figure 10As shown, the snap-fit ​​component 1000 includes a snap-fit ​​arm 1001 and a snap-fit ​​connector 1002. One end of the snap-fit ​​arm 1001 passes through the snap-fit ​​hole 202. The snap-fit ​​connector 1002 is located at the other end of the snap-fit ​​arm 1001 and is placed outside the base 200. In use, the snap-fit ​​arm 1001 is inserted into the snap-fit ​​hole 202 and contacts the connecting rod 500. The snap-fit ​​connector 1002 limits the insertion position of the snap-fit ​​arm 1001. The size of the snap-fit ​​connector 1002 is larger than the size of the snap-fit ​​hole 202, thereby preventing the snap-fit ​​connector 1002 from entering the base 200 along with the snap-fit ​​arm 1001. In addition, an operating groove is provided on the snap-fit ​​connector 1002. When the snap-fit ​​arm 1001 is inserted into or pulled out of the snap-fit ​​hole 202, the operating groove can be pinched with fingers to prevent the fingers from slipping when operating the snap-fit ​​connector 1002. Preferably, the operating groove is an arc-shaped groove, the size of which is adapted to the fingertip for easy pinching operation.

[0044] Of course, to improve the stability of the snap-fit ​​arm 1001 after contacting the connecting rod 500, it is preferable that the snap-fit ​​arm 1001 is provided with a contact groove 1003, which is adapted to the connecting rod 500. When the snap-fit ​​arm 1001 contacts the connecting rod 500, the connecting rod 500 enters the contact groove 1003. The contact groove 1003 can restrict the position of the snap-fit ​​arm 1001 and reduce the probability of the snap-fit ​​arm 1001 disengaging from the connecting rod 500. In this utility model, the connecting rod 500 is a cylindrical rod and the contact groove 1003 is an arc-shaped groove.

[0045] like Figures 6-8 As shown, a sealing groove 203 is provided on the base 200, and a sealing strip (not shown in the figure) is provided in the sealing groove 203. A sealing block 703 is provided on the watch case 100. In the connected state, the sealing block 703 is placed in the sealing groove 203. Through the cooperation of the sealing groove 203, the sealing block 703 and the sealing strip, the watch case 100 and the base 200 are sealed together to prevent dust and other particles from entering the interior and affecting the operation of the functional unit. In this utility model, the sealing strip is preferably a rubber strip. In addition, when the sealing block 703 is placed in the sealing groove 203, the elastic deformation force generated by the compression of the sealing strip will push the watch case 100 to move away from the base 200. This thrust is transmitted to the operating head 902, making the fit between the limiting plate 901 and the limiting groove 212 tighter, and further improving the firmness of the connection between the watch case 100 and the base 200.

[0046] like Figure 7 and Figure 8As shown, a first inclined surface 611 is provided on the first connecting plate 601, and a second inclined surface 711 is provided on the second connecting plate 701. The first inclined surface 611 and the second inclined surface 711 are adapted to each other. When the connecting rod 500 and the connecting arm 400 are engaged, the first inclined surface 611 and the second inclined surface 711 come into contact. In addition, when engaging the connecting rod 500 and the connecting arm 400, the first inclined surface 611 and the second inclined surface 711 can be used for guidance to improve the accuracy of the installation of the connecting rod 500 and the connecting arm 400.

[0047] During installation, insert the connecting rod 500 of the watch case 100 into the slots of the two connecting arms 400 of the base 200, so that the inclined surfaces of the first connecting plate 601 and the second connecting plate 701 are in contact, completing the initial positioning of the watch case and the base; slide the slider 800 of the cover 300 into one end of the second slide groove 702 until the slider 800 slides into the first slide groove 602 and aligns the mounting hole 301 with the guide groove 211; and then install the limiting plate of the fixing member 900. After passing through the mounting hole 301 and the guide groove 211, 901 is placed in the limiting groove 212. The operating head 902 is rotated to make the limiting plate 901 snap into the limiting groove 212, thus completing the limiting and locking of the cover. The snap arm 1001 of the snap connector 1000 is inserted into the snap hole 202 of the base 200, so that the connecting rod 500 is snapped into the contact groove 1003, thus completing the anti-detachment limiting of the connecting rod 500. At this point, the case 100 and the base 200 are fixedly connected.

[0048] During disassembly, pinch the operating groove of the snap-fit ​​connector 1002 to pull the snap-fit ​​piece 1000 out of the snap-fit ​​hole 202, releasing the restriction on the connecting rod 500; rotate the operating head 902 of the fixing piece 900 to rotate the limiting plate 901 from the limiting groove 212 to the guide groove 211, pull the fixing piece 900 out of the mounting hole 301, releasing the restriction on the cover 300; slide the slider 800 of the cover 300 out of the first sliding groove 602 and the second sliding groove 702 to release the locking state between the watch case 100 and the base 200; disengage the connecting rod 500 of the watch case 100 from the slot of the connecting arm 400 to complete the disassembly of the watch case and the base.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
