Description

Technical Field

[0001] This utility model relates to the field of metering box technology, and in particular to an assembly device for an electrical energy metering box circuit breaker. Background Technology

[0002] For example, publication number "CN119448044A" discloses "a modular outdoor power metering box," which includes a box body. The front end of the box body is hinged to three hinged doors. A first mounting cavity is formed on one side of the inner wall of the box body, a second mounting cavity is formed in the middle of the inner wall, and a third mounting cavity is formed on the other side of the inner wall. Multiple stabilizing components are arranged on the inner wall of the second mounting cavity, and three fixing plates are fixedly connected to the inner wall of each second mounting cavity. A first bidirectional threaded rod and a second bidirectional threaded rod are rotatably connected to both sides of the inner wall of each fixing plate. However, in practical applications, no protection is provided at the circuit breaker positions inside the box, potentially posing a safety risk. Since the number and location of the circuit breakers are not fixed, if protection is implemented, it would require changes based on different installation methods, increasing manufacturing costs and making it impossible to adapt to the circuit breakers. Summary of the Invention

[0003] In view of the problem mentioned in the background art that the existing technology cannot adapt to the protection of circuit breakers, this utility model provides an assembly device for an electricity metering box circuit breaker, which can be installed according to the actual use needs during use, improving the adaptability to different installation needs, and meeting the protection requirements after installation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] An assembly device for an electricity metering box circuit breaker includes an assembly of mounting plates. The mounting plates have mounting grooves, and the bottom of the mounting grooves has a cutout. Several pre-processed plates are connected to the cutout, and several mounting positions are provided on the cutout. Each pre-processed plate includes a protective plate, which is positioned at each mounting position. A loose connection section is provided between the protective plate and the cutout, the size of which is smaller than the size of the protective plate. Several outwardly opening plates are slidably connected to the end face of the mounting groove. In this application, the mounting plate assembly is provided with mounting slots capable of accommodating circuit breakers. The size of the mounting slot is much larger than the size of a single circuit breaker, thus allowing multiple circuit breakers to be installed within the mounting slot. The bottom of the mounting slot has a cutout section, on which several pre-processed plates are mounted. Each pre-processed plate corresponds to a mounting position, and each mounting position corresponds to a specific circuit breaker. Because the pre-processed plates are mounted on the cutout section, and a loose connection section is provided between the pre-processed plates and the cutout section, this loose connection section is small in size and has low connection strength. Therefore, during use, the loose connection section can be quickly disconnected or cut open with a tool. Since the size of the loose connection section is smaller than the size of the protective plate, there is a gap without connection between the pre-processed plates and the edges of the cutout section, thereby reducing the complexity of removing the pre-processed plates. Furthermore, when no circuit breaker is installed, the pre-processed plates and the cutout section... There are connections between them, so the entire hollow section is protected by pre-processed plates. When several circuit breakers need to be installed, the pre-processed plates at the corresponding installation positions of the circuit breakers are removed, leaving the installation positions empty to accommodate the circuit breakers. After the circuit breakers are placed in, there are still pre-processed plates at the remaining installation positions where no circuit breakers are installed. Therefore, even if the circuit breakers in the installation slot are not fully installed, there are still pre-processed plates at the positions where no circuit breakers are installed, thus protecting the internal space and ensuring adaptability to different circuit breaker installation requirements. At the same time, the protection effect of the internal space can be guaranteed when installing circuit breakers with different arrangements. In addition, there is an outward opening plate that slides on the end face of the installation slot. The outward opening plate can slide to open and close the installation slot, thereby protecting the internal space of the installation slot and further enhancing the protection effect.

[0006] Preferably, the mounting groove end face is provided with a plurality of guide protrusions, and the outer opening plate is provided with a sliding groove, the sliding groove being slidably connected to the guide protrusions. The protrusions on the mounting groove end face provide a guiding effect by limiting the sliding groove of the outer opening plate, thereby ensuring the movement stability and positioning accuracy of the outer opening plate.

[0007] Preferably, the electricity metering box has several windows aligned with the installation positions. Guide rails are provided on the sides of the windows, and guide grooves are provided on the sides of the outer opening plate, slidably connected to the guide rails. The windows on the electricity metering box protect the entire internal space. The windows are aligned with the installation positions, and the outer opening plate is slidably connected to the windows. Guide rails are provided on both sides of the windows, and guide grooves are provided on the outer opening plate. The guide rails and guide grooves are slidably connected, ensuring the sliding stability of the outer opening plate. When the outer opening plate slides open, the windows can be opened, revealing the circuit breakers installed at the installation positions behind the windows, allowing operators to quickly operate the circuit breakers. Several windows are provided, corresponding to various installation positions, so that each window can be used to operate circuit breakers in different locations, while also restricting operation to avoid interference with other circuit breakers.

[0008] Preferably, the outer opening plate is provided with a push-pull groove. The push-pull groove facilitates the operation of the outer opening plate by the staff.

[0009] Preferably, the push-pull groove has a limiting protrusion on the side near the mounting plate assembly. When the outer opening plate slides, the limiting protrusion can abut against the mounting plate assembly. The push-pull groove forms a groove-shaped structure on the outer side of the outer opening plate, and correspondingly, it forms a protrusion structure on the inner side of the outer opening plate, that is, a limiting protrusion is formed on one side of the mounting plate assembly. This allows the limiting protrusion to abut against the guide protrusion during the sliding process of the outer opening plate, thereby limiting and constraining the outer opening plate and preventing it from sliding out of the window.

[0010] Preferably, the mounting plate assembly has several openings. These openings allow various wires and screws to pass through, ensuring ease of installation and facilitating wire threading.

[0011] Preferably, the opening includes a disassembly / assembly hole and a wire threading hole. The opening is divided into a disassembly / assembly hole and a wire threading hole, and the shapes of the disassembly / assembly hole and the wire threading hole are not the same, so as to facilitate the differentiation by the staff.

[0012] Preferably, the detachable connection segment is provided with at least one detachable connection hole. Providing at least one detachable connection hole further reduces the difficulty of disassembling the detachable connection segment and makes installation more convenient for workers.

[0013] Preferably, the outer opening plate is provided with a viewing window that allows observation of the internal circuit breaker. The viewing window on the outer opening plate allows for observation of the internal situation, facilitating monitoring by staff.

[0014] Preferably, the mounting plate assembly includes raised surrounding plates extending towards the outward-opening side, with mounting grooves formed between the raised surrounding plates. The raised surrounding plates on the mounting plate assembly, forming mounting grooves, thus create a receiving space for the circuit breaker.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) It can be installed according to actual usage needs during use, which improves the adaptability to different installation needs, and at the same time, it can meet the protection requirements after installation.

[0017] (2) The circuit breaker can be further protected by sliding the outer opening plate, thereby improving the protection effect;

[0018] (3) Improve the ease of disassembly of pre-processed plates and increase assembly efficiency. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1:

[0030] like Figure 1As shown, an electrical metering box circuit breaker assembly device includes a mounting plate assembly 1, a mounting groove 11 on the mounting plate assembly 1, a hollow part 12 at the bottom of the mounting groove 11, a plurality of pre-processed plates 13 connected to the hollow part 12, a plurality of mounting positions 14 on the hollow part 12, the pre-processed plates 13 including protective plates 131, the protective plates 131 being disposed on each mounting position 14, a loose connection section 132 being provided between the protective plates 131 and the hollow part 12, the size of the loose connection section 132 being smaller than the size of the protective plates 131, and a plurality of outwardly opening plates 2 being slidably connected to the end face of the mounting groove 11. In this application, the mounting plate assembly 1 is provided with a mounting groove 11 capable of accommodating circuit breakers. The size of the mounting groove 11 is much larger than the size of a single circuit breaker, so multiple circuit breakers can be installed in the mounting groove 11. The bottom of the mounting groove 11 is provided with a cutout portion 12, and multiple pre-processed plates 13 are provided on the cutout portion 12. Each pre-processed plate 13 corresponds to a mounting position 14, and each mounting position 14 corresponds to a circuit breaker. Since the pre-processed plates 13 are installed on the cutout portion 12, and a loose connection section 132 is provided between the pre-processed plates 13 and the cutout portion 12, the loose connection section 132 is small in size and has low connection strength. Therefore, during use, the loose connection section 132 can be quickly disconnected or cut with a tool. Since the size of the loose connection section 132 is smaller than the size of the protective plate 131, there is a gap without connection between the pre-processed plate 13 and the edge of the cutout portion 12, thereby reducing the complexity of removing the pre-processed plate 13. Furthermore, when no circuit breaker is installed... Each pre-processed plate 13 is connected to the hollowed-out portion 12, so the entire hollowed-out portion 12 is protected by the pre-processed plate 13. When several circuit breakers need to be installed, the pre-processed plate 13 on the corresponding installation position 14 of the circuit breaker is removed. At this time, the installation position 14 is empty and can accommodate the circuit breaker. After the circuit breaker is placed in, there are still pre-processed plates 13 on the other installation positions 14 where no circuit breaker is installed. Therefore, even if the circuit breaker in the installation slot 11 is not completely installed, there are still pre-processed plates 13 in the positions where no circuit breaker is installed, thus protecting the internal space and ensuring adaptability to different circuit breaker installation requirements. At the same time, the protection effect of the internal space can be guaranteed when installing circuit breakers with different arrangements. Furthermore, an outer opening plate 2 is slidably connected to the end face of the installation slot 11. The outer opening plate 2 can slide to open and close the installation slot 11, thereby protecting the internal space of the installation slot 11 and further enhancing the protection effect.

[0031] like Figure 1As shown, the mounting plate assembly 1 has several openings 16, including disassembly / removal holes and wire threading holes. These openings 16 allow various wires and screws to pass through, ensuring ease of installation and facilitating wire threading. The openings 16 are divided into disassembly / removal holes and wire threading holes, with different shapes for easy differentiation by operators.

[0032] like Figure 2 As shown, at least one virtual connection hole 133 is provided in the virtual connection section 132. The virtual connection section 132 is provided with at least one virtual connection hole 133, which can further reduce the difficulty of disassembling the virtual connection section 132 and make it more convenient for workers to install it.

[0033] like Figure 3 As shown, the outer opening plate 2 is provided with a viewing window 25 that allows observation of the internal circuit breaker. The viewing window 25 on the outer opening plate 2 allows observation of the internal situation, facilitating observation by staff.

[0034] like Figure 1 As shown, the mounting plate assembly 1 includes raised surrounding plates 17 extending toward the outward opening plate 2, and mounting grooves 11 are formed between the raised surrounding plates 17. The raised surrounding plates 17 are provided on the mounting plate assembly 1, and the mounting grooves 11 are formed by the raised surrounding plates 17, thereby forming a receiving space for the circuit breaker.

[0035] Example 2:

[0036] like Figure 1As shown, an electrical metering box circuit breaker assembly device includes a mounting plate assembly 1, a mounting groove 11 on the mounting plate assembly 1, a hollow part 12 at the bottom of the mounting groove 11, a plurality of pre-processed plates 13 connected to the hollow part 12, a plurality of mounting positions 14 on the hollow part 12, the pre-processed plates 13 including protective plates 131, the protective plates 131 being disposed on each mounting position 14, a loose connection section 132 being provided between the protective plates 131 and the hollow part 12, the size of the loose connection section 132 being smaller than the size of the protective plates 131, and a plurality of outwardly opening plates 2 being slidably connected to the end face of the mounting groove 11. In this application, the mounting plate assembly 1 is provided with a mounting groove 11 capable of accommodating circuit breakers. The size of the mounting groove 11 is much larger than the size of a single circuit breaker, so multiple circuit breakers can be installed in the mounting groove 11. The bottom of the mounting groove 11 is provided with a cutout portion 12, and multiple pre-processed plates 13 are provided on the cutout portion 12. Each pre-processed plate 13 corresponds to a mounting position 14, and each mounting position 14 corresponds to a circuit breaker. Since the pre-processed plates 13 are installed on the cutout portion 12, and a loose connection section 132 is provided between the pre-processed plates 13 and the cutout portion 12, the loose connection section 132 is small in size and has low connection strength. Therefore, during use, the loose connection section 132 can be quickly disconnected or cut with a tool. Since the size of the loose connection section 132 is smaller than the size of the protective plate 131, there is a gap without connection between the pre-processed plate 13 and the edge of the cutout portion 12, thereby reducing the complexity of removing the pre-processed plate 13. Furthermore, when no circuit breaker is installed... Each pre-processed plate 13 is connected to the hollowed-out portion 12, so the entire hollowed-out portion 12 is protected by the pre-processed plate 13. When several circuit breakers need to be installed, the pre-processed plate 13 on the corresponding installation position 14 of the circuit breaker is removed. At this time, the installation position 14 is empty and can accommodate the circuit breaker. After the circuit breaker is placed in, there are still pre-processed plates 13 on the other installation positions 14 where no circuit breaker is installed. Therefore, even if the circuit breaker in the installation slot 11 is not completely installed, there are still pre-processed plates 13 in the positions where no circuit breaker is installed, thus protecting the internal space and ensuring adaptability to different circuit breaker installation requirements. At the same time, the protection effect of the internal space can be guaranteed when installing circuit breakers with different arrangements. Furthermore, an outer opening plate 2 is slidably connected to the end face of the installation slot 11. The outer opening plate 2 can slide to open and close the installation slot 11, thereby protecting the internal space of the installation slot 11 and further enhancing the protection effect.

[0037] like Figure 1 , 3As shown, several guide protrusions 15 are provided on the end face of the mounting groove 11, and a sliding groove 21 is provided on the outer opening plate 2. The sliding groove 21 is slidably connected to the guide protrusions 15. The protrusions on the end face of the mounting groove 11 can provide a guiding effect to limit the sliding groove 21 of the outer opening plate 2, thereby ensuring the movement stability and positioning accuracy of the outer opening plate 2.

[0038] like Figure 5 As shown, the electricity metering box has several windows 3 aligned with the installation position 14. Guide rails 31 are provided on the sides of the windows 3, and guide grooves 22 are provided on the sides of the outer opening plate 2, which are slidably connected to the guide rails 31. The windows 3 protect the entire internal space. The windows 3 are aligned with the installation position 14, and the outer opening plate 2 is slidably connected to the windows 3. Guide rails 31 are provided on both sides of the windows 3, and guide grooves 22 are provided on the outer opening plate 2. The guide rails 31 and guide grooves 22 are slidably connected, ensuring the sliding stability of the outer opening plate 2. When the outer opening plate 2 slides open, the windows 3 can be opened, revealing the circuit breakers installed at the installation position 14 behind the windows 3, allowing operators to quickly operate the circuit breakers. Several windows 3 are provided, corresponding to each installation position 14, so that each window 3 can operate circuit breakers in different positions, while also restricting operation to avoid interference with other circuit breakers.

[0039] like Figure 4 As shown, the outward opening plate 2 is provided with a push-pull groove 23. The push-pull groove 23 on the outward opening plate 2 facilitates the operation of the outward opening plate 2 by the staff.

[0040] like Figure 3 As shown, the push-pull groove 23 forms a limiting protrusion 24 on the side near the mounting plate assembly 1. When the outer opening plate 2 slides, the limiting protrusion 24 can abut against the mounting plate assembly 1. The push-pull groove 23 forms a groove-shaped structure on the outer side of the outer opening plate 2, and correspondingly, the push-pull groove 23 forms a protrusion structure on the inner side of the outer opening plate 2, that is, a limiting protrusion 24 is formed on one side of the mounting plate assembly 1. This allows the limiting protrusion 24 to abut against the guide protrusion 15 during the sliding process of the outer opening plate 2, thereby limiting and constraining the outer opening plate 2 and preventing the outer opening plate 2 from sliding out of the window 3.

[0041] like Figure 1 As shown, the mounting plate assembly 1 has several openings 16. These openings 16 allow various wires and screws to pass through, ensuring ease of installation and facilitating wire threading.

[0042] like Figure 1As shown, the opening 16 includes a disassembly / assembly hole and a wire threading hole. The opening 16 is divided into a disassembly / assembly hole and a wire threading hole, and the shapes of the disassembly / assembly hole and the wire threading hole are not the same, so as to facilitate the workers to distinguish them.

[0043] like Figure 2 As shown, at least one virtual connection hole 133 is provided in the virtual connection section 132. The virtual connection section 132 is provided with at least one virtual connection hole 133, which can further reduce the difficulty of disassembling the virtual connection section 132 and make it more convenient for workers to install it.

[0044] like Figure 4 As shown, the outer opening plate 2 is provided with a viewing window 25 that allows observation of the internal circuit breaker. The viewing window 25 on the outer opening plate 2 allows observation of the internal situation, facilitating observation by staff.

[0045] like Figure 1 As shown, the mounting plate assembly 1 includes raised surrounding plates 17 extending toward the outward opening plate 2, and mounting grooves 11 are formed between the raised surrounding plates 17. The raised surrounding plates 17 are provided on the mounting plate assembly 1, and the mounting grooves 11 are formed by the raised surrounding plates 17, thereby forming a receiving space for the circuit breaker.

[0046] The assembly and operation process of the circuit breaker assembly device for the power metering box in this embodiment is as follows: In this embodiment, six windows 3 are provided on the body of the power metering box. The windows 3 have a hollow structure, and an outer opening plate 2 is slidably connected to the windows 3. There are gaps between the windows 3, and the windows 3 are not connected to each other. Guide rails 31 are provided on both sides of each window 3, and guide grooves 22 are provided on both sides of the outer opening plate 2. The guide rails 31 and guide grooves 22 are slidably connected, so that the outer opening plate 2 can be slidably connected to each window 3. The sliding direction of the outer opening plate 2 is upward. The slide plate 2 has a push-pull groove 23 on its outer side. The push-pull groove 23 is located on the outer side of the outer opening plate 2, and a limiting protrusion 24 is formed on the inner side of the outer opening plate 2. A sliding groove 21 is provided on the inner side of the outer opening plate 2. A mounting plate assembly 1 is provided behind the window 3. A mounting groove 11 is provided on the mounting plate assembly 1. A guide protrusion 15 is provided on the end face of the mounting groove 11, that is, the side of the mounting groove 11 near the window 3. The guide protrusion 15 is connected to the sliding groove 21 of the outer opening plate 2. A viewing window 25 is also provided on the outer opening plate 2. The status of the internal circuit breaker can be observed through the viewing window 25. A mounting groove 11 is provided on the mounting plate assembly 1. A raised surrounding plate 17 is provided on the side facing the window 3, forming the mounting groove 11 between the raised surrounding plates 17. A hollow portion 12 is formed at the bottom of the mounting groove 11. Multiple pre-processed plates 13 are arranged side-by-side on the hollow portion 12. In this embodiment, the lateral dimension of the pre-processed plate 13 is half the lateral dimension of the mounting position 14. That is, removing two pre-processed plates 13 from the hollow portion 12 forms one mounting position 14. In this embodiment, a pre-processed plate 13 is also retained between each mounting position 14. The pre-processed plate 13 includes a protective plate 131 and a loose connection section 132, wherein the protective plate 131... The protective plate 131 is the main structure, while the dummy connection section 132 is set at the upper and lower ends of the protective plate 131. The lateral dimension of the dummy connection section 132 is smaller than that of the protective plate 131. Dummy connection holes 133 are provided on the dummy connection section 132. Therefore, when processing and installing the plate assembly 1, the entire hollow part 12 is equipped with pre-processed plates 13. During installation, two pre-processed plates 13 are removed from the hollow part 12 corresponding to the installation position 14 to form the installation position 14. When the circuit breaker is installed on each corresponding installation position 14, a pre-processed plate 13 is left between adjacent circuit breakers, thereby avoiding the exposure of the internal space and ensuring the protection effect.
