[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention is further described below in conjunction with the embodiments. The terms "left", "right", "front", "back", "upper" and "lower" mentioned in the following description are oriented in the viewing direction of the front view.

[0030] Embodiment 1: In some embodiments, please refer to Figures 1 - 10, A combined power metering device, including a cabinet body 1, further comprising: a combined stacking device 2, a quick-drawing device 3, and a wire bundling device 4. A plurality of the combined stacking devices 2 are installed on the cabinet body 1. The quick-drawing device 3 is installed on the upper side inside the cabinet body 1. The wire bundling device 4 is installed on the lower side inside the cabinet body 1. Two first strip-shaped openings 5 are provided on the upper side of the cabinet body 1. The quick-drawing device 3 includes: a fixed guide rail 31, fixed rollers 32, an L-shaped baffle 33, a sliding guide rail 34, and sliding rollers 35. The two fixed guide rails 31 are respectively fixedly installed on the left and right sides inside the cabinet body 1. The fixed rollers 32 are rotatably connected to the front side of the fixed guide rail 31 through a rotating shaft. A protrusion 36 is provided on the front side of the fixed guide rail 31. The L-shaped baffle 33 is fixedly installed at the position of the protrusion 36. The sliding guide rail 34 is slidably connected to the fixed guide rail 31. The sliding rollers 35 are rotatably connected to the rear side of the sliding guide rail 34 through a rotating shaft. The quick-drawing device 3 further includes: a support mechanism, and the support mechanism is installed on the sliding guide rail 34. A cabinet door is hinged on the cabinet body 1, and a transparent plate is fixedly installed on the cabinet door. The transparent plate facilitates observing the internal condition of the cabinet body 1.

[0031] The combined stacking device 2 enables the device to be quickly stacked and combined to meet different power metering requirements. Through the combined stacking device 2, it can also be quickly unlocked and popped out, enabling the device to quickly unlock and exit the combined state with one key. The quick-drawing device 3 can quickly extract the electronic components inside the device and rotate a preset angle at the same time, facilitating maintenance personnel to repair or replace the device. The wire bundling device 4 can adapt to the extraction or retraction of the quick-drawing device 3, enabling the cable to always remain taut to achieve adaptive cable laying or winding up, and avoiding cable entanglement from hindering maintenance.

[0032] Such as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 As shown, when the sliding guide rail 34 moves away from the cabinet body 1, it drives the sliding guide rail 34 to move away from the cabinet body 1. When the sliding guide rail 34 moves away from the cabinet body 1, it drives the sliding rollers 35 to move away from the cabinet body 1. The sliding rollers 35 stop when they reach the position of the protrusion 36 of the fixed guide rail 31. Under the restriction of the L-shaped baffle 33, the sliding rollers 35 move upward, causing the front side of the sliding guide rail 34 to automatically tilt downward. The fixed rollers 32 are used to reduce the friction of the front and back movement of the sliding guide rail 34.

[0033] The support mechanism includes: a moving plate 37, a vertical bracket 38, a first magnet 39, and a second magnet 310. The moving plate 37 is fixedly installed on the sliding guide rail 34. A second strip-shaped opening 311 is provided at the rear side of the moving plate 37. A plurality of the vertical brackets 38 are fixedly installed on the upper side of the moving plate 37. Two of the first magnets 39 are fixedly installed on the rear side of the moving plate 37. Two of the second magnets 310 are fixedly installed on the rear side wall of the cabinet body 1. The first magnets 39 and the second magnets 310 are in one-to-one correspondence, and the first magnets 39 and the second magnets 310 attract each other.

[0034] Pull out the moving plate 37 of the support mechanism of the quick pull-out device 3 outward. The movement of the moving plate 37 away from the cabinet body 1 drives the sliding guide rail 34 and the first magnet 39 to move away from the cabinet body 1. The movement of the sliding guide rail 34 away from the cabinet body 1 drives the sliding roller 35 to move away from the cabinet body 1. The sliding roller 35 stops when it moves to the position of the protrusion 36 of the fixed guide rail 31. Under the restriction of the L-shaped baffle 33, the sliding roller 35 moves upward, causing the front side of the sliding guide rail 34 to automatically tilt downward. The automatic downward tilt of the front side of the sliding guide rail 34 drives the moving plate 37 to tilt downward, facilitating the maintenance or replacement of the electronic devices on the vertical brackets 38 of the moving plate 37.

[0035] When the maintenance or replacement is completed, insert the moving plate 37 back to the initial position. At this time, the first magnet 39 on the rear side of the moving plate 37 approaches the second magnet 310, and the mutual attraction between the first magnet 39 and the second magnet 310 quickly fixes the moving plate 37.

[0036] Embodiment 2: In some embodiments, as Figures 1 - 10 shown, as a preferred embodiment of the present invention, the wire bundling device 4 includes: a linear guide rail 41, a slider 42, a connecting plate 43, and a guide wheel 44. Two of the linear guide rails 41 are fixedly installed in the cabinet body 1. The slider 42 is slidably connected to the linear guide rail 41. The connecting plate 43 is fixedly installed on the upper side of the slider 42. The guide wheel 44 is rotatably connected to the upper side of the connecting plate 43 through a rotating shaft.

[0037] The wire bundling device 4 further includes: an elastic component, and the elastic component is installed in the cabinet body 1.

[0038] The elastic component includes: a first gas spring 45, an upper pressure plate 46, and a lower pressure plate 47. One end of the first gas spring 45 is fixedly installed on the connecting plate 43, and the other end of the first gas spring 45 is fixedly installed on the cabinet body 1. The upper pressure plate 46 is fixedly installed below the second strip-shaped opening 311, and the lower pressure plate 47 is fixedly installed below the upper pressure plate 46.

[0039] As Figure 6 、 Figure 7As shown, the bus cable harness of the electronic device on the vertical bracket 38 of the moving plate 37 is arranged at the position of the upper pressing plate 46 of the cable bundling device 4. The upper pressing plate 46 and the lower pressing plate 47 are fixedly connected together by fixing screws. The cable is fixed at the position of the second strip-shaped opening 311 of the moving plate 37 by combining the lower pressing plate 47 and the upper pressing plate 46. At this time, the cable passes through two guide wheels 44 and is fixedly connected to the left side of the cabinet body 1.

[0040] When the moving plate 37 is pulled out, the cable moves away from the cabinet body 1. The cable is pulled, and the movement of the cable drives the two guide wheels 44 to approach each other. The movement of the guide wheels 44 drives the connecting plate 43 to move. The movement of the connecting plate 43 causes the first air spring 45 to undergo elastic deformation and be compressed. The slider 42 and the linear guide rail 41 are used to limit the left and right movement of the connecting plate 43.

[0041] When the moving plate 37 is inserted back into the cabinet body 1, the cable moves into the cabinet body 1. The cable is pushed back. At this time, the first air spring 45 that has undergone elastic deformation resumes its original state, pushing the two guide wheels 44 back to the initial position. The guide wheels 44 return to the initial position to re-stretch and tighten the cable, so that the cable will not be wound due to the movement of the moving plate 37.

[0042] The combined stacking device 2 includes: a support frame 21, a support spring 22, a sliding plate 23, and support feet 24. The four support frames 21 are respectively fixedly installed at the four corner positions on the upper side of the cabinet body 1. One end of the support spring 22 is fixedly connected inside the support frame 21. The sliding plate 23 is slidably connected to the support frame 21. The other end of the support spring 22 is fixedly connected to the lower side of the sliding plate 23. The four support feet 24 are respectively fixedly installed at the four corner positions on the lower side of the cabinet body 1. The positions of the support feet 24 and the sliding plate 23 correspond one by one. A slot 25 is provided on one side of the support feet 24, and a first inclined surface 26 is provided on the lower side of the support feet 24.

[0043] The combined stacking device 2 further includes: a locking assembly. The locking assembly is installed on the upper side of the cabinet body 1. The locking assembly includes: a fixing plate 27, a limiting rod 28, a C-shaped bracket 29, a plug-in block 210, and a cover plate 211. The two fixing plates 27 are respectively fixedly installed on the upper side of the cabinet body 1. The two limiting rods 28 are fixedly installed between the two fixing plates 27. The two C-shaped brackets 29 are slidably connected to the limiting rods 28. A plug-in block 210 is slidably connected to the side of each support frame 21 close to the center of the cabinet body 1. One end of the plug-in block 210 away from the support frame 21 is fixedly installed on the C-shaped bracket 29. The cover plate 211 is fixedly installed on the upper side of the cabinet body 1. A second inclined surface 212 is provided on the side of the plug-in block 210 away from the center of the cabinet body 1.

[0044] As Figure 2 、 Figure 3 、 Figure 4 、Figure 5 As shown, the locking assembly further includes an elastic assembly. The elastic assembly is installed on the C-shaped bracket 29. The elastic assembly includes a second gas spring 213 and a toggle rod 214. Second gas springs 213 are fixedly installed on one side of the C-shaped bracket 29 close to the center of the cabinet 1. One end of the second gas spring 213 away from the C-shaped bracket 29 is fixedly connected to the cabinet 1. The middle side of the toggle rod 214 is slidably connected to the first strip-shaped opening 5, and the upper side of the toggle rod 214 is fixedly installed on the lower side of the C-shaped bracket 29.

[0045] When multiple devices need to be stacked and combined, insert the support feet 24 of the upper device into the support frame 21 of the lower device. At this time, the support feet 24 move towards the sliding plate 23. The first inclined surface 26 of the support feet 24 and the second inclined surface 212 of the plug-in block 210 come into contact first. The downward movement of the support feet 24 drives the plug-in block 210 to move towards the center of the cabinet 1. The movement of the plug-in block 210 towards the center of the cabinet 1 causes the second gas spring 213 to undergo elastic deformation and be compressed. The support feet 24 move downward to the position of the sliding plate 23. At this time, the second gas spring 213 that has undergone elastic deformation and been compressed restores, and pushes the plug-in block 210 into the slot 25 of the support feet 24. At the same time, the downward movement of the support feet 24 drives the sliding plate 23 to move downward, causing the support spring 22 to undergo elastic deformation and be compressed. The support spring 22 provides an upward supporting force to the sliding plate 23, so that the support feet 24 on the upper side of the sliding plate 23 are stably fixed on the plug-in block 210.

[0046] When the combined state of the devices needs to be released, toggle the two toggle rods 214 towards the center of the cabinet 1. The movement of the toggle rods 214 towards the center of the cabinet 1 drives the C-shaped bracket 29 to move towards the center of the cabinet 1. The movement of the C-shaped bracket 29 towards the center of the cabinet 1 drives the plug-in block 210 to move towards the center of the cabinet 1. The plug-in block 210 leaves the slot 25 of the support feet 24. The support spring 22 that has undergone elastic deformation restores and pushes the sliding plate 23 upward. The upward movement of the sliding plate 23 drives the support feet 24 to move upward, so that when the devices are released from the combined state, they automatically pop up upward.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
