Technical Field

[0001] This utility model belongs to the field of three-phase energy meter technology, specifically a convenient installation type three-phase rail-mounted energy meter. Background Technology

[0002] Three-phase rail-mounted energy meters, as professional instruments for measuring the energy consumption of three-phase AC circuits, play a crucial role in power systems. They adopt a standard rail mounting method, which has the advantages of compact structure and small space occupation, making them easy to install and arrange in equipment such as distribution boxes and distribution cabinets. However, some three-phase rail-mounted energy meters have the problem of cumbersome operation during installation and disassembly.

[0003] A search revealed Chinese Patent Publication No. CN 222965299 U, which discloses a rail-mounted three-phase energy meter. The meter includes a top plate with a rail fixedly connected to its lower surface. The rail has grooves and multiple sets of equidistant and symmetrical positioning slots. Two connecting blocks are inserted into the grooves and then quickly positioned into the two positioning slots at different distances. Two connecting brackets are fixedly connected to the three-phase energy meter. This allows the meter to adapt to different sizes by controlling the two connecting blocks to be positioned in the positioning slots at different intervals. The rail has multiple first through holes located within each positioning slot, and each first through hole has a first threaded groove aligned vertically. Bolts pass through the first and second through holes and are screwed into the first threaded groove, causing the connecting blocks to move upwards and press against the upper wall of the groove, thus quickly fixing the connecting blocks in place.

[0018] Specific implementation examples are given below.

[0019] Please see Figures 1-5This utility model provides a convenient installation type three-phase rail-mounted energy meter, including a rail mounting bracket 1; the side wall of the rail mounting bracket 1 contacts the energy meter body 2, a push plate 4 is slidably connected to the side wall of the energy meter body 2, a connecting plate 41 is rotatably connected to the inner wall of the end of the push plate 4, a sliding groove 21 is formed on the side wall of the end of the energy meter body 2, a rectangular plate 42 is slidably connected to the middle of the sliding groove 21, the end of the connecting plate 41 is rotatably connected to the end of the rectangular plate 42, and a locking block 43 is fixedly connected to the bottom of the other end of the rectangular plate 42, the locking block 43 is slidably connected to the inner side of the rail mounting bracket 1. The top of the guide rail mounting bracket 1 has a limiting groove 3, and the locking block 43 is inserted into the middle of the limiting groove 3. The side wall of the energy meter body 2 is provided with a wire fixing screw 6, and the side wall of the energy meter body 2 is provided with a protective component. The side wall of the push plate 4 has a groove 48, and a ball bearing 47 is slidably connected in the middle of the groove 48. During operation, when it is necessary to disassemble the energy meter body 2, it is only necessary to push the push plate 4. At this time, one end of the connecting plate 41 will rotate with the push plate 4, and the angle of the connecting plate 41 will also change. The other end of the connecting plate 41 will rotate with the rectangular plate 42, and drive it to rotate. The rectangular plate 42 slides in the middle of the slide groove 21, which drives the locking block 43 to move until the locking block 43 is completely disengaged from the middle of the limiting groove 3. Then, the main body 2 of the electricity meter can be removed. The removal process does not require tools and is not affected by wiring, improving convenience. During installation, the main body 2 of the electricity meter is simply clipped onto the outer wall of the guide rail mounting bracket 1. During the clipping process, the guide rail mounting bracket 1 will move along the inclined surface of the locking block 43. The locking block 43 will drive the rectangular plate 42 to move, and the rectangular plate 42 will move the push plate 4 via the connecting plate 41. The slider 44 will slide in the middle of the second groove 22 and squeeze the first spring 45 until the locking block 43 coincides with the limiting groove 3. At this time, the first spring 45 will push the slider 44 and the push plate 4 to reset through its own elasticity. The connecting plate 41, the rectangular plate 42 and the locking block 43 will also reset. The locking block 43 will insert into the middle of the limiting groove 3 to limit the energy meter body 2, which improves convenience. In addition, when the push plate 4 moves, if its side wall contacts another set of energy meter bodies 2, the ball 47 will roll on the side wall of the other set of energy meter bodies 2 to ensure the smooth movement of the push plate 4.

[0020] Furthermore, such as Figure 1 and Figure 3As shown, the protective assembly includes a fixing block 51, which is fixedly connected to the side wall of the electricity meter body 2. A round rod 52 is rotatably connected to the side wall of the fixing block 51. A cover plate 5 is fixedly connected to the end of the round rod 52. An insert plate 53 is slidably connected to the middle of the cover plate 5. A rectangular groove 23 is opened on the side wall of the electricity meter body 2. The insert plate 53 is inserted into the middle of the rectangular groove 23. A pull plate 55 is fixedly connected to the bottom of the insert plate 53. The pull plate 55 is slidably connected to the bottom of the cover plate 5. A spring 54 is fixedly connected to the bottom of the insert plate 53 on one side of the pull plate 55. The bottom of the spring 54 is fixedly connected to the middle of the cover plate 5. During operation, when it is necessary to rotate the wire fixing screw 6 to fix the wire, the cover plate 5 needs to be opened. When needed, the pull plate 55 can be pulled to move the insert plate 53. When the insert plate 53 moves, it will squeeze the second spring 54 until the insert plate 53 is disengaged from the middle of the rectangular slot 23. At this time, the cover plate 5 can be pushed to open it until the cover plate 5 is in a horizontal state. At this time, the insert plate 53 will overlap with another set of rectangular slots 23. Release the pull plate 55. At this time, the second spring 54 will push the insert plate 53 to move in the opposite direction through its own elasticity, so that the insert plate 53 is inserted into the middle of another set of rectangular slots 23. Then, the cable fixing screw 6 can be rotated to fix the cable. After the cable fixing screw 6 is rotated, the cover plate 5 can be closed to protect the cable fixing screw 6. The closing operation is the same as above. This can reduce the risk of the cable fixing screw 6 being damaged by dust.

[0021] Furthermore, such as Figure 2 and Figure 5 As shown, a second groove 22 is provided at the center of the side wall of the main body 2 of the electricity meter. A slider 44 is elastically connected to the middle of the second groove 22 by a spring 45. The end of the slider 44 is fixed to the side wall of the push plate 4, and the outer wall of the slider 44 is slidably connected to the middle of the second groove 22. One end of the spring 45 is fixed to the middle of the second groove 22, and the other end of the spring 45 is fixed to the side wall of the slider 44. During operation, when the push plate 4 moves, it will drive the slider 44 to move in the middle of the second groove 22 and squeeze the spring 45. The T-shape of the slider 44 ensures the stability of the connection between the push plate 4 and the main body 2 of the electricity meter, while the spring 45 has a certain elasticity to ensure the stability of the insertion of the locking block 43 into the middle of the limiting groove 3.

[0022] Furthermore, such as Figure 2 and Figure 4 As shown, a protective plate 46 is fixed to the top side of the end of the rectangular plate 42. The protective plate 46 is slidably connected to the top of the electricity meter body 2. During operation, the protective plate 46 can seal the slide groove 21, reducing the risk of dust entering the middle of the electricity meter body 2 through the slide groove 21, and ensuring the stability of the circuit in the middle of the electricity meter body 2.

[0023] Furthermore, such as Figure 2 As shown, the bottom side of the card block 43 is set as an inclined surface. During operation, the inclined surface eliminates the need to push the push plate 4 when installing the main body of the electricity meter 2, thus further improving the installation efficiency.

[0024] Furthermore, such as Figure 2 As shown, multiple sets of connecting plates 41, rectangular plates 42, locking blocks 43, and protective plates 46 are provided, and these multiple sets of connecting plates 41, rectangular plates 42, locking blocks 43, and protective plates 46 are symmetrically arranged with the center line of the electricity meter body 2 as the axis of symmetry. During operation, the cooperation between the multiple sets of connecting plates 41, rectangular plates 42, locking blocks 43, and protective plates 46 can limit the movement of multiple sides of the electricity meter body 2, ensuring the stability of the limit.

[0025] Furthermore, such as Figure 3 As shown, a sealing strip 56 is fixed to the side wall of the cover plate 5. A sealing groove 24 is provided on the side wall of the main body 2 of the electricity meter, located outside the wire fixing screw 6. The sealing strip 56 contacts the middle of the sealing groove 24. During operation, the sealing strip 56 and the sealing groove 24 cooperate to ensure that the cover plate 5 can seal the periphery of the wire fixing screw 6 when closed, thus ensuring the protection of the wire fixing screw 6 by the cover plate 5.

[0026] Working principle: When it is necessary to disassemble the main body 2 of the electricity meter, simply push the push plate 4. At this time, one end of the connecting plate 41 will rotate with the push plate 4, and the angle of the connecting plate 41 will also change. The other end of the connecting plate 41 will rotate with the rectangular plate 42, causing the rectangular plate 42 to slide in the middle of the slide groove 21. The rectangular plate 42 will drive the locking block 43 to move until the locking block 43 is completely disengaged from the middle of the limiting groove 3, and the main body 2 of the electricity meter can be disassembled. The disassembly process does not require the use of tools and is not affected by the wiring, which improves convenience. During installation, simply clip the main body 2 of the electricity meter onto the outer wall of the guide rail mounting bracket 1. During the clipping process, the guide rail mounting bracket 1 will move along the inclined surface of the locking block 43. When pushed to move, the locking block 43 will drive the rectangular plate 42 to move. The rectangular plate 42 will move the push plate 4 through the connecting plate 41. The push plate 4 will drive the slider 44 to slide in the middle of the second slide groove 22 and squeeze the first spring 45 until the locking block 43 coincides with the limiting groove 3. At this time, the first spring 45 will push the slider 44 and the push plate 4 to reset through its own elasticity. The connecting plate 41, the rectangular plate 42 and the locking block 43 will also reset. The locking block 43 will insert into the middle of the limiting groove 3 to limit the energy meter body 2, which improves convenience. In addition, when the push plate 4 moves, if its side wall contacts another set of energy meter bodies 2, the ball bearing 47 will roll on the side wall of the other set of energy meter bodies 2 to ensure the smooth movement of the push plate 4.

[0027] When the cable needs to be fixed by rotating the cable fixing screw 6, the cover plate 5 needs to be opened. When opening, the pull plate 55 can be pulled to move the insert plate 53. When the insert plate 53 moves, it will squeeze the second spring 54 until the insert plate 53 is disengaged from the middle of the rectangular groove 23. At this time, the cover plate 5 can be pushed to open it until the cover plate 5 is in a horizontal state. At this time, the insert plate 53 will coincide with another set of rectangular grooves 23. Release the pull plate 55. At this time, the second spring 54 will push the insert plate 53 to move in the opposite direction through its own elasticity, so that the insert plate 53 is inserted into the middle of another set of rectangular grooves 23. Then the cable fixing screw 6 can be rotated to fix the cable. After the cable fixing screw 6 is rotated, the cover plate 5 can be closed to protect the cable fixing screw 6. The closing operation is the same as above.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
