[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1-Figure 5As shown, the utility model proposes a single-phase multi-meter metal meter box that is easy to adjust, including a metal box 1, a lifting plate 3 that can be slidably installed inside the metal box 1 and can be adjusted in height in the vertical direction, and a wire box 5 is fixedly installed on the top of the lifting plate 3. The side panels of the metal box 1 and the wire box 5 are both provided with wire entry holes to ensure that external cables can pass through the metal box 1 and enter the inside of the wire box 5. The inside of the above-mentioned wire box 5 is fixedly provided with a plurality of built-in partitions 51, and the inside of the wire box 5 is divided into a plurality of independent storage intervals by the built-in partitions 51, which can partition and store the branch lines connected to the meter, and the top of the built-in partition 51 is provided with an arc-shaped opening, and the main line pulled into the wire box 5 is clamped in the arc-shaped opening. When the top cover 52 is fixed to the top opening of the wire box 5, the main cable can be pressed and positioned; the back panel of the above-mentioned metal box 1 is provided with a plurality of long strip openings 11, and the long strip openings 11 are fixedly provided with When the lock 8 and the limit plate 12 are firmly locked, the lifting plate 3 can be locked and fixed to prevent it from sliding down, ensuring that the meter installed on the top of the lifting plate 3 can be stably installed inside the metering box; the opening end of the above-mentioned metal box 1 is rotatably mounted with a box door 7 by a hinge, and a glass plate is fixedly mounted on the box door 7, so that the data on the meter can be conveniently observed through the glass plate. A rotary lock is fixedly mounted on the box door 7, and when the box door 7 is closed, it is fixed to the opening end of the metal box 1 by the rotary lock, effectively preventing it from rotating at will.

[0032] Furthermore, built-in shelf plates 2 are fixedly installed on the two inner side walls of the metal box 1 through brackets, and a limiting slide groove structure is carved on one side of the built-in shelf plates 2. Limiting blocks are fixedly installed on both ends of the lifting plate 3 arranged between the two built-in shelf plates 2. The above-mentioned limiting blocks are embedded in the matching limiting slide groove structure and slidably connected thereto to ensure that the lifting plate 3 can be stably slid and installed between the two built-in shelf plates 2; a heat dissipation vent structure is carved on the side panel of the above-mentioned metal box 1, which is conducive to the discharge of heat inside the metal box 1 and improves its heat dissipation effect; installing the built-in shelf plates 2 inside the metal box 1 can provide a complete sliding adjustment surface for the end of the lifting plate 3. Compared with directly sliding the end of the lifting plate 3 on the inner wall of the metal box 1, the heat dissipation vent structure can be avoided from obstructing the limit blocks installed at the end of the lifting plate 3.

[0033] Secondly, a plurality of slides 32 are fixedly installed on the top of the lifting plate 3, and a T-shaped slide groove structure with two ends of openings is cut on the top of the slide groove. A plurality of sliders 41 of T-shaped structures are fixedly installed on the bottom of the support plate 4. The above-mentioned sliders 41 are embedded in the matching T-shaped slide groove structure and slidably connected therewith to ensure that the support plate 4 can be stably slid and installed on the top of the slide groove 32. When the meter is installed on the top of the support plate 4, it is convenient to adjust the meter in the horizontal direction when maintaining it, so that the meter can be closer to the position of the box door 7, which is convenient for the staff to operate; the top of the above-mentioned lifting plate 3 is fixedly installed with a first positioning plate 31, and the support plate 4 is fixedly installed with a second positioning plate 42 at the bottom, and the first positioning plate 31 is set at a position between the second positioning plate 42 and the junction box 5. When it is necessary to pull the support plate 4 to the side of the box door 7, the second positioning plate 42 can be prevented from blocking the first positioning plate 31; a bolt is threadedly installed on the above-mentioned first positioning plate 31, one end of the bolt passes through the first positioning plate 31 and is threadedly connected to the second positioning plate 42. When the support plate 4 is restored to its original position, the first positioning plate 31 and the second positioning plate 42 can be firmly connected as a whole through the above-mentioned bolt to prevent the support plate 4 from moving, thereby ensuring that the meter can be firmly installed on the top of the lifting plate 3.

[0034] It is worth noting that a protective cover 6 is fixedly installed on the back plate of the above-mentioned metal box 1, and the end of the lock 8 extending to the outside of the metal box 1 is arranged inside the protective cover 6. The open end of the protective cover 6 is fixed with a sealing plate by screws. The lock 8 can be adjusted by opening the sealing plate, and the adjustment operation of the lifting plate 3 can be completed outside the metal box 1, which is more convenient; when the sealing plate is fixed to the open end of the protective cover 6, it can prevent the lock 8 from being accidentally touched, causing the lifting plate 3 to enter an unlocked state, thereby preventing it from causing the meter to slide down.

[0035] The lock 8 is composed of a sleeve 81, a spring sleeve 82, a locking rod 83 and a spring 84. One end of the sleeve 81 is fixed to the side of the wiring box 5 away from the box door 7, ensuring that the lock 8 and the wiring box 5 are firmly connected as a whole; an opening structure is carved out on the sleeve 81, and a limit plate 12 arranged inside the elongated opening 11 passes through the above-mentioned opening structure, so that the sleeve 81 can be movably installed on the limit plate 12, which is convenient for lifting and lowering adjustment of the lock 8; the end of the sleeve 81 away from the wiring box 5 is fixedly equipped with a spring sleeve 82, and the locking rod 83 is movably installed inside the spring sleeve 82. A circular plate is fixedly installed on the outer wall of the locking rod 83 and inside the spring sleeve 82. The above-mentioned spring 84 is movably sleeved on the outer wall of the locking rod 83, and one end of the spring 84 is fixedly connected to the inner wall of the spring sleeve 82 away from the end of the sleeve 81, and the other end of the spring 84 is fixed to the above-mentioned circular plate When the end of the locking rod 83 is inserted into the inner positioning groove 121, the wiring box 5 and the lifting plate 3 can be locked and fixed, thereby preventing the lifting plate 3 from sliding downward, effectively improving the stability of the lifting plate 3 and the meter installed on its top after the height adjustment.

[0036] In this embodiment, the meter, control switch and other components are first fixed on the top of the support plate 4, the external cables are passed through the wire holes set on the side panels of the metal box 1 into the box body, and then the main cable is pulled in from the wire holes drilled at the end of the junction box 5, the main cable is clamped in the arc-shaped opening on the top of the built-in partition 51, the branch line is pulled out from the perforation on the side of the junction box 5 close to the support plate 4, and it is connected and fixed to the terminal posts of the meter, control switch and other components. At this time, a sufficiently long branch line can be reserved inside the junction box 5, and the top cover 52 is fixed at the top opening of the junction box 5, and then the main cable is pressed and fixed to ensure that the main cable and the branch line reserved inside the junction box 5 can be stably stored inside the box. In this way, not only can a sufficiently long cable be reserved inside the metal box 1, but the cables can also be arranged in an orderly manner in a limited space, reducing the space occupied by the cables inside the metal box 1.

[0037] When it is necessary to maintain the meter, the staff first opens the sealing plate installed on the protective cover 6, and then pulls the locking rod head 85 to the side away from the metal box 1, and then drives the locking rod 83 to move to the side away from the limit plate 12. When the end of the locking rod 83 is pulled out from the positioning groove 121, the locking fixation of the wiring box 5 and the lifting plate 3 can be released. At this time, pushing the locker 8 in the vertical direction can drive the lifting plate 3 to move vertically, which is convenient for adjusting the height of the lifting plate 3, thereby increasing the space on the top of the meter. When the height adjustment of the lifting plate 3 is completed, release the lock. The rod head 85, at this time the compressed spring 84 returns to the expanded state, and then pushes the locking rod 83 to move to the side of the limit plate 12. When the end of the locking rod 83 is inserted into the positioning groove 121 again, the junction box 5 and the lifting plate 3 can be locked and fixed, effectively preventing the lifting plate 3 from sliding down. After opening the box door 7, the bolts installed on the first positioning plate 31 can be removed, and then the connection between the first positioning plate 31 and the second positioning plate 42 can be released. At this time, the support plate 4 can be pulled toward the side of the box door 7 to make the meter closer to the box door 7, effectively improving the convenience of the meter maintenance operation.

[0038] During the meter maintenance stage, when the lifting plate 3 moves in the vertical direction, the branch cables stored in the wire box 5 will be pulled out a distance, avoiding insufficient cable reserved length to make it impossible to adjust the height of the lifting plate 3, solving the problem of insufficient cable reserved length hindering the adjustment of the lifting plate 3; when the meter maintenance is completed, the lifting plate 3 needs to be restored to its original position. Since the cable has a certain hardness and good bending performance, during the process of the lifting plate 3 returning to its original position, the branch cables are subjected to the external force of the lifting plate 3 and can be retracted into the box again along the wire holes drilled on the wire box 5, thereby reducing the probability of cable entanglement and effectively preventing the cables from being arranged in a messy manner.

[0039] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
