Description

Technical Field

[0001] This invention belongs to the field of electricity meter technology and relates to a modular electricity meter box. Background Technology

[0002] A modular power metering box is a distribution box that standardizes and modularizes functional units such as power metering, protection, monitoring, and data acquisition. In existing technologies, when fabricating power meters or electrical components and installing them into the metering box, multiple screws are typically used to fix them to the box, requiring the tightening of multiple screws for installation or removal, which is cumbersome.

[0003] A modular assembly-type distribution box is disclosed in patent document CN119029707A, including a distribution box body, a distribution box door for opening and closing the distribution box body, a capacitor, a cooling fan for cooling the interior of the distribution box body, and a power supply for driving the various components. The cooling fan is fixedly connected to the upper inner wall of the distribution box body. The distribution box door is hinged to the side of the opening of the distribution box body. A first partition plate is fixedly connected inside the distribution box body. A second partition plate is fixedly connected between the first partition plate and the distribution box door. The capacitor is fixedly connected to the second partition plate. A quick-connect assembly for quickly connecting the distribution box components to be installed is connected to the side of the first partition plate facing the distribution box door. This technical solution allows for the modular assembly and disassembly of various components within the distribution box, reducing the maintenance difficulty and labor intensity for workers.

[0004] However, this distribution box has the following shortcomings in use. First, the meter needs to be placed on the corresponding guide assembly, and then the locking plate needs to be moved outward to engage with the screw. When moving the locking plate outward, the meter needs to be held still by hand to ensure that the screw aligns with the corresponding locking slot. However, due to hand fatigue, the meter may shift. If the meter shifts vertically, the locking slot may not be properly engaged with the corresponding screw. If the screw is aligned with the locking slot by moving the meter up and down, it is also easy for the screw to not be inserted into the corresponding locking slot, resulting in some screws not engaging with the locking plate and thus affecting the fixing effect.

[0005] To address the above problems, this invention proposes a modular power metering box. Summary of the Invention

[0006] To address the problems existing in the background technology, the present invention proposes a modular power metering box.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a modular electricity metering box, comprising a box body; the box body is provided with a plurality of mounting modules for installing electricity meters; The installation module includes a mounting base fixed inside the housing and a first connecting member; both ends of the mounting base are provided with arc-shaped grooves; two sliders are elastically slidably arranged in each arc-shaped groove, and a rotating shaft is rotatably connected between the two sliders; the first connecting member includes a push plate, a top plate, and an elastic arc-shaped plate; the push plate and the top plate are both fixedly connected to the rotating shaft, the arc-shaped plate is fixedly connected to the push plate, and a push groove is provided on the push plate; a locking block for locking the top plate is elastically slidably arranged on the inner wall of the arc-shaped groove; The meter is equipped with a second connector that mates with the first connector. The second connector includes a vertical plate, a first horizontal plate, and a second horizontal plate. The vertical plate is fixed to the back of the meter. The first horizontal plate is fixedly connected to the vertical plate. The second horizontal plate is fixedly connected to the side of the first horizontal plate away from the meter.

[0008] Furthermore, the upper and lower sides of the second horizontal plate both protrude from the first horizontal plate.

[0009] Furthermore, the mounting base has a locking groove that slides through the upper and lower end faces of the mounting base; a push block is fixedly connected to the end of the locking block.

[0010] Furthermore, a torsion spring is fitted onto the rotating shaft, and the torsion spring is fixedly connected between the slider and the rotating shaft.

[0011] Furthermore, each of the installation modules includes two mounting bases, which are arranged one above the other.

[0012] Furthermore, the housing is provided with a sliding groove that slides with the slider, and a first spring is fixedly connected between the slider and the end wall of the sliding groove.

[0013] Furthermore, the end of the arc-shaped plate away from the push plate is arc-shaped; the end of the top plate away from the rotating shaft is arc-shaped.

[0014] Furthermore, a cable tray is provided inside the housing at the position corresponding to the installation module.

[0015] Furthermore, a control compartment is provided on one side of the enclosure.

[0016] Compared with the prior art, the present invention has the following advantages: the meter can be fixed on the mounting base simply by aligning the first connecting piece with the corresponding second connecting piece and then pushing the meter inward. Since the second horizontal plate and the first horizontal plate are inserted into the gap between the two corresponding arc plates, the arc plates have a limiting effect on the meter. During the installation process, the movement of the meter will not affect the installation process.

[0017] To remove the meter, simply push the push block inward to release the limit on the top plate. Installation and removal are both simple and convenient.

[0018] The push plate is engaged with and abuts against the first horizontal plate through the push groove. The curved plate bends and deforms, causing the second horizontal plate to abut against the push plate, thereby limiting the meter in multiple directions and fixing the meter stably to the mounting base.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-11 As shown, the technical solution adopted by the present invention is as follows: A modular power metering box includes a box body 1 and an installation module.

[0023] The enclosure 1 contains multiple mounting modules for mounting the electricity meter 18. These modules allow for easy and secure mounting of the electricity meter 18 inside the enclosure 1.

[0024] The mounting module includes mounting base 5 and a first connector. There are two mounting bases 5, which are arranged symmetrically one above the other. The mounting bases 5 are fixed inside the housing 1.

[0025] like Figure 2 , Figure 3 As shown, arc-shaped grooves 6 are provided at both ends of the mounting base 5. The two arc-shaped grooves 6 on the same mounting base 5 are symmetrically arranged. Two sliders 8 are elastically slidably disposed within each arc-shaped groove 6. Specifically, the two sliders 8 within the same arc-shaped groove 6 are slidably disposed on the upper and lower sides of the mounting base 5, respectively. A sliding groove 7 is provided on the mounting base 5 to slide and engage with the sliders 8. The sliders 8 are slidably disposed within the sliding groove 7, and a first spring 9 is disposed within the sliding groove 7. The first spring 9 is fixedly connected between the slider 8 and one end wall of the sliding groove 7. Initially, under the action of the first spring 9, the slider 8 abuts against the end of the sliding groove 7 near the middle of the mounting base 5.

[0026] A rotating shaft 10 connects two sliders 8 within the same arc-shaped groove 6. The rotating shaft 10 is vertically positioned. A torsion spring is fitted onto the rotating shaft 10, and the torsion spring is fixedly connected between the rotating shaft 10 and the slider 8.

[0027] Each arc-shaped groove 6 is provided with a first connecting member. The first connecting member includes a push plate 11, an arc-shaped plate 13, and a top plate 14. Both the push plate 11 and the top plate 14 are fixedly connected to the rotating shaft 10. Multiple arc-shaped plates 13 are fixedly connected to the side of the push plate 11 away from the rotating shaft 10, and the arc-shaped plates 13 are elastic. Push grooves 12 are formed on the push plate 11 between adjacent arc-shaped plates 13. The end of the arc-shaped plate 13 away from the push plate 11 is arc-shaped. There is a certain included angle between the top plate 14 and the push plate 11. In this embodiment, the included angle between the top plate 14 and the push plate 11 is greater than 90 degrees. The end of the top plate 14 away from the rotating shaft 10 is arc-shaped.

[0028] A locking block 16 for locking the top plate 14 is elastically slidably mounted on the inner wall of the arc-shaped groove 6. Specifically, a locking groove 15 is formed on the inner wall of the arc-shaped groove 6, passing through the upper and lower ends of the mounting base 5. A push block 17 is fixedly mounted on the end of the locking block 16, extending outside the mounting base 5. A second spring 22 is provided inside the locking groove 15. One end of the second spring 22 is fixedly connected to the locking block 16, and the other end of the second spring 22 is fixedly connected to the inner wall of the locking groove 15. Under the action of the second spring 22, the locking block 16 extends outside the locking groove 15.

[0029] The meter 18 is equipped with a second connector that mates with the first connector, and each first connector is provided with a second connector.

[0030] like Figure 4 , Figure 5 As shown, each second connector includes a vertical plate 19, a first horizontal plate 20, and a second horizontal plate 21. The vertical plate 19 is fixedly installed on the back of the meter 18. Multiple first horizontal plates 20 are fixedly installed at intervals on the inward-facing side of the vertical plate 19, and a second horizontal plate 21 is fixedly installed on the side of each first horizontal plate 20 away from the meter 18. The upper and lower sides of the second horizontal plate 21 protrude from the first horizontal plate 20. The end of the second horizontal plate 21 away from the vertical plate 19 extends to the outside of the first horizontal plate 20.

[0031] In this embodiment, three first horizontal plates 20 are fixedly connected to the inner side of each vertical plate 19. Four arc-shaped plates 13 are fixedly installed at intervals on each push plate 11, and correspondingly, three push grooves 12 are provided on the push plate 11. The three push grooves 12 correspond one-to-one with the three first horizontal plates 20, and the push grooves 12 are engaged with the corresponding first horizontal plates 20. The push plate 11 abuts against the first horizontal plate 20 through the push grooves 12.

[0032] like Figure 6 , Figure 7 As shown, during installation, hold the meter 18 by hand and mate the second connector with the corresponding first connector, so that the first horizontal plate 20 in the second connector is inserted into the gap between the two corresponding arc-shaped plates 13. Then, push the meter 18 towards the mounting base 5 to fix the meter 18 onto the mounting base 5.

[0033] A cable tray 4 is installed inside the enclosure 1, and the cable tray 4 is located below the corresponding installation module. A control compartment 2 is provided on one side of the enclosure 1.

[0034] After the meter 18 is fixed inside the housing 1 by the installation module, the wire is connected to the meter 18, and then the wire is connected to the control compartment 2 through the cable tray 4.

[0035] Box 1 is equipped with box door 3.

[0036] Working principle: Initially, such as Figure 6 , Figure 8 As shown, under the action of the first spring 9, the slider 8 abuts against the end of the slide groove 7 near the other arc-shaped groove 6. Under the action of the torsion spring, the push plate 11 and the arc-shaped plate 13 deflect outward. There is a certain gap between the top plate 14 and the corresponding locking block 16. Under the action of the second spring 22, the locking block 16 extends outside the locking groove 15.

[0037] When using, such as Figure 6 , Figure 7 as well as Figure 8 As shown, the second connector on the back of the meter 18 is aligned with the corresponding first connector, and the first horizontal plate 20 and the second horizontal plate 21 are inserted into the gap between the corresponding two arc-shaped plates 13. At this time, as... Figure 8 As shown.

[0038] Pushing the meter 18 towards the mounting base 5 causes the arc-shaped plate 13, at the end furthest from the rotating shaft 10, to abut against the back of the meter 18, causing the meter 18 to push the first connector to rotate around the rotating shaft 10 via the arc-shaped plate 13. Figure 8 The direction shown causes the top plate 14 to rotate toward the locking block 16.

[0039] It should be noted that the stiffness coefficient of the arc plate 13 is greater than that of the torsion spring. In other words, the meter 18 will first push the first connecting piece to rotate through the arc plate 13, rather than deforming the arc plate 13.

[0040] As the meter 18 gradually approaches the mounting base 5, the arc-shaped plate 13 slides along the back of the meter 18 towards the vertical plate 19, and the push plate 11 gradually approaches the first horizontal plate 20. The top plate 14 gradually approaches the locking block 16, as... Figure 9 As shown, the installation module is in the second state at this time, with the top plate 14 in contact with the locking block 16.

[0041] Then, the meter 18 is pushed closer to the mounting base 5, the first connector continues to rotate around the pivot 10, and the push plate 11 changes to a horizontal position. The top plate 14 pushes the locking block 16 to slide into the locking groove 15, while the slider 8 slides outward along the first slide groove 7, and the first connector moves outward along the first slide groove 7. The push plate 11 and the arc plate 13 move closer to the vertical plate 19. At this time, the mounting module is in the third state, as shown... Figure 10 As shown.

[0042] The meter 18 continues to be pushed closer to the mounting base 5. The top plate 14 continues to rotate and presses the locking block 16, causing the locking block 16 to slide into the locking groove 15. When the end of the top plate 14 abuts against the inner wall of the arc groove 6, the slider 8 moves outward along the slide groove 7 against the elastic force of the first spring 9 due to the blocking action of the inner wall of the arc groove 6. The rotating shaft 10 drives the push plate 11 and the arc plate 13 to move outward, so that the push groove 12 on the push plate 11 is engaged with the corresponding first horizontal plate 20. When the end of the arc plate 13 contacts the vertical plate 19, the arc plate 13 bends and deforms as the first connecting piece continues to move closer to the vertical plate 19 due to the blocking action of the vertical plate 19. Since the arc plate 13 has a certain degree of curvature in its natural state, and the outer convex surface of the arc plate 13 is close to the meter 18, when the arc plate 13 is compressed, the arc plate 13 bends and deforms in the direction closer to the meter 18.

[0043] Until, as Figure 11 As shown, the top plate 14 passes over the locking block 16. Under the action of the second spring 22, the locking block 16 extends outside the locking groove 15, and the top plate 14 abuts against the side of the locking block 16 closest to the meter 18. The push plate 11 is in a horizontal state, and the push plate 11 abuts against the first horizontal plate 20 through the push groove 12. The outward protrusion of the arc plate 13 abuts against the back of the meter 18, and the second horizontal plate 21 abuts against the push plate 11. At this time, the installation module is in the fourth state, that is, the state after the meter 18 is installed. Under the limitation of the locking block 16, the top plate 14 cannot be reset and rotated. At the same time, under the limitation of the inner wall of the arc groove 6, the first spring 9 remains in a compressed state.

[0044] At this time, the push plate 11 is engaged with and abuts against the first horizontal plate 20 via the push groove 12, causing the meter 18 to tend to move outward. Under the action of the two push plates 11 on the same mounting base 5, the left and right sides of the meter 18 have opposite movement tendencies, thereby fixing the meter 18 to the mounting base 5. At the same time, the arc plate 13 has the tendency to push the vertical plate 19 outward, further increasing the stability of the meter 18. The outward protrusion of the arc plate 13 abuts against the back of the meter 18, causing the meter 18 to tend to move away from the mounting base 5, causing the second horizontal plate 21 to abut against the push plate 11. Under the action of the push plate 11, the second horizontal plate 21, and the arc plate 13, the meter 18 is more stably fixed to the mounting base 5.

[0045] Then, connect the wire to the meter 18 and connect the wire to the control compartment 2 through the cable tray 4.

[0046] When the meter 18 needs to be repaired or replaced, it needs to be removed from the mounting module. First, disconnect the wires.

[0047] Next, push the push block 17 inward, causing the locking block 16 to slide into the locking groove 15, thereby releasing the lock on the top plate 14. Under the action of the torsion spring, the first connecting member returns to its original position and rotates. At the same time, under the action of the first spring 9 and the arc plate 13, the first connecting member slides towards the center of the mounting base 5. Then, the meter 18 can be removed.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
