Description

Technical Field

[0001] This application relates to the technical field of meter boxes, and in particular to an outdoor meter box. Background Technology

[0002] In outdoor power facility layouts, wall-mounted meter boxes are indispensable and crucial equipment. They bear the heavy responsibility of protecting key electrical components such as meters and metering devices, ensuring the stable operation of the power system and safe metering. Their installation location is typically on an outdoor wall, requiring ease of meter reading and maintenance, as well as adaptability to various environmental conditions. However, in practical applications, due to factors such as differences in building structure, adjustments to power line planning, or changes in usage needs, the installation height of meter boxes often needs to be flexibly adjusted to better suit the actual site conditions.

[0003] Currently, common wall-mounted meter boxes mainly consist of a box body and a door installed on the box body. To meet the needs of outdoor installation, several fixing lugs are fixedly installed on the outer edge of the side of the box body away from the door. These fixing lugs have carefully prepared through holes. During the installation of the meter box, workers will use professional tools to precisely pass the screws through the fixing through holes and then firmly screw them into the pre-drilled screw holes in the wall. In this way, the meter box is firmly fixed to the wall, ensuring its stable use in outdoor environments.

[0004] In practical applications, the installation height of electrical meter boxes often needs to be adjusted due to various factors. Taking local climate and topography as an example, if the original installation height is too low, it is easily susceptible to waterlogging during the rainy season, leading to moisture inside the meter box and damage to electrical components. To adjust the height, workers must first use specialized tools to unscrew the screws one by one, releasing the meter box from the wall. Afterward, a suitable hole must be drilled in the wall for installation. The entire process is cumbersome, consuming significant manpower and time, increasing adjustment costs, and potentially damaging the wall structure during repeated drilling, leaving room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an outdoor meter box that solves the problems of cumbersome, inefficient and costly readjustment of the installation height of the meter box in the above-mentioned related technologies.

[0006] The outdoor meter box provided in this application adopts the following technical solution: An outdoor electricity meter box includes a base plate fixed to a wall, a box body mounted on the base plate, and a door mounted on the box body. Wiring holes are provided on the vertical sides of the box body. Adjustment plates are rotatably mounted on opposite vertical sides of the box body. First and second insert rods, arranged vertically along a horizontal direction, are slidably mounted on the box body. A linkage is provided on the outside of the box body. When the adjustment plates rotate, the linkage drives the first and second insert rods to slide towards and away from each other. A first protrusion facing the second insert rod is fixed to the end of the first insert rod away from the door. A second protrusion facing the first protrusion is fixed to the second insert rod. The base plate has several first slots for inserting the first insert rod and sliding vertically, and second slots for inserting the second insert rod and sliding vertically. First and second grooves are respectively formed on the inner walls of the first and second slots. When the first and second insert rods slide towards each other, the first and second protrusions respectively engage with the first and second grooves.

[0007] By adopting the above technical solution, the rotation of the adjusting plate drives the first and second insert rods to slide towards or away from each other via a linkage. When the first and second protrusions respectively engage with the first and second grooves, a stable connection is achieved between the box and the base plate. To adjust the height, simply reverse the operation of the adjusting plate to disengage the protrusions from the grooves, allowing the box to slide back and forth on the base plate in the vertical direction. Once a suitable height is selected, the protrusions are re-engaged into the corresponding grooves. The entire process is simple to operate, greatly saving manpower and time, improving adjustment efficiency, reducing adjustment costs, and avoiding damage to the wall structure from repeated drilling. It better meets the need for flexible installation height adjustments in practical applications.

[0008] Optionally, the adjusting plate is fixed with a rotating shaft that is rotatably connected to the vertical outer side of the housing, and the adjusting plate can reciprocate around the rotating shaft; the rotating surface of the adjusting plate is parallel to the vertical surface of the housing where the rotating shaft is located, and the outside of the housing is provided with a locking member to limit the rotation state of the adjusting plate.

[0009] By adopting the above technical solution, the adjustment plate is rotatably connected to the vertical outer side of the box through a rotating shaft and can reciprocate around the shaft. This design makes the rotation of the adjustment plate flexible and stable, and can accurately control its rotation angle, providing a reliable basis for subsequently driving the first and second insertion rods to slide to achieve box height adjustment.

[0010] Optionally, the adjusting plate is provided with a locking through hole, and the outer side of the housing is provided with a locking thread groove that can coincide with the locking through hole. The locking component is a locking bolt that passes through the locking through hole and is screwed into the locking thread hole.

[0011] By adopting the above technical solution, after the adjusting plate is rotated to the appropriate position and the height of the meter box is adjusted, the locking bolt is passed through the locking through hole on the adjusting plate and screwed into the corresponding locking thread groove on the outer side of the box. This connection method is simple, direct, and reliable. The overlapping design of the locking through hole and the locking thread groove provides precise installation positioning for the locking bolt, ensuring that the locking operation can be completed quickly and accurately.

[0012] Optionally, the linkage includes a first folding rod vertically fixed to the end of the first insert rod away from the substrate, and a second folding rod to the end of the second insert rod away from the substrate. The first and second folding rods are bent in a direction that brings them closer to each other. A linkage rod is slidably provided on the vertical outer surface of the housing in the horizontal direction. Two connecting rods are rotatably connected to the end of the linkage rod away from the door. The ends of the first and second folding rods are rotatably connected to the other ends of the two connecting rods, respectively. An adjusting rod is rotatably connected to the outer periphery of the adjusting plate. The other end of the adjusting rod is rotatably connected to the end of the linkage rod away from the substrate. The linkage rod can slide back and forth in the horizontal direction when the adjusting plate rotates, so that the first insert rod and the second insert rod slide towards each other and away from each other.

[0013] By adopting the above technical solution, when the adjusting plate rotates, it drives the adjusting rod to move, which in turn pushes the linkage rod to slide back and forth in the horizontal direction. The sliding of the linkage rod, in turn, drives the first and second folding rods to move through the connecting rod, ultimately realizing the sliding of the first and second insert rods towards or away from each other. This ingenious structural design converts the rotation of the adjusting plate into the linear motion of the first and second insert rods. The transmission process is stable and precise, effectively controlling the sliding distance and position of the first and second insert rods, ensuring that the first and second protrusions accurately engage or disengage from the first and second grooves, achieving a stable connection or flexible separation between the housing and the base plate.

[0014] Optionally, a first guide block is fixed on the outer side of the housing, and the first guide block has a guide through hole through which the linkage rod passes and slides.

[0015] By adopting the above technical solution, during the process of the adjustment plate rotating and driving the linkage rod to slide horizontally, the first guide block can effectively restrict the movement trajectory of the linkage rod, so that it always slides stably along the direction of the guide through hole, avoiding the linkage rod from deviating or shaking during the sliding process, ensuring the accuracy and stability of the sliding of the first and second insert rods towards or away from each other, and thus ensuring that the first and second protrusions can accurately engage or disengage from the first and second grooves.

[0016] Optionally, an extension protrusion is fixedly provided on the lower part of the two opposite vertical sides of the box body. The extension protrusion has several mounting through holes. The outside of the box body is provided with a support vertical rod that passes through the mounting through holes and a movable wheel installed on the lower end face of the support vertical rod. The lower edge of the opening of the mounting through hole is provided with a mounting groove for the movable wheel to be inserted. The inner wall of the mounting through hole is provided with a reset member that drives the movable wheel to move upward. The adjustment plate is provided with a positioning member. When the adjustment plate is in the state where the first protrusion is dislodged from the first groove, the positioning member drives the support vertical rod to move downward and protrude out of the mounting groove.

[0017] By adopting the above technical solution, when the adjusting plate causes the first protrusion to disengage from the first groove, meaning the box and the base plate can move relative to each other, the positioning component drives the supporting vertical rod to move downwards, causing the moving wheel to protrude from the mounting slot. At this time, the meter box can be easily moved, greatly facilitating the flexible adjustment of the meter box's position when adjusting its height and saving manpower. The mounting slot can store the moving wheel when the meter box does not need to be moved, ensuring the stability of the meter box's placement. The reset component can drive the moving wheel upwards and retract when no movement is required, avoiding long-term damage to the moving wheel due to stress.

[0018] Optionally, a limiting baffle is fixedly provided on the outer periphery of the supporting vertical rod, and a clearance groove is provided on the upper edge of the opening of the mounting through hole for the limiting baffle to be inserted and slid. The reset component includes a reset spring with both ends fixedly connected to the bottom side of the clearance groove and the bottom surface of the limiting baffle, respectively.

[0019] By adopting the above technical solution, the clearance groove provides sliding space for the limiting baffle, making the up-and-down movement of the supporting vertical rod smoother. The return spring, as a reset component, has its two ends connected to the bottom side of the clearance groove and the bottom surface of the limiting baffle, respectively. After the moving wheel protrudes from the mounting groove and the supporting vertical rod moves downward, the return spring is stretched. When the meter box does not need to be moved, the spring force automatically drives the supporting vertical rod upward, causing the moving wheel to retract into the mounting groove, achieving an automatic reset function that is simple and reliable to operate.

[0020] Optionally, the positioning component includes a positioning protrusion fixed on the outer periphery of the adjusting plate, a positioning rod horizontally positioned above the extension protrusion, and a positioning protrusion fixed on the upper side of the positioning rod. The upper end faces of several supporting vertical rods on the same side are all fixedly connected to the lower side of the positioning rod. The outer periphery of the positioning protrusion away from the adjusting plate is a guide slope. When the positioning protrusion rotates with the adjusting plate to a vertically downward position, it is located directly above the positioning protrusion. At this time, the positioning protrusion presses against the positioning protrusion, causing the supporting vertical rod to move downward.

[0021] By adopting the above technical solution, the positioning convex plate rotates with the adjusting plate. When it rotates to a vertically downward position directly above the positioning protrusion, the guide ramp smoothly presses against the positioning protrusion, thereby driving the positioning rod downward. This causes the supporting vertical rod connected to the positioning rod to move downward synchronously, allowing the moving wheel to protrude from the mounting groove, thus enabling the meter box to move. This design cleverly controls the extension and retraction of the moving wheel through the rotation of the adjusting plate, making operation simple and highly interconnected. The guide ramp reduces friction and jamming between components, making the fit between the positioning convex plate and the positioning protrusion smoother, and improving the reliability and durability of the structure.

[0022] Optionally, the second insert is located below the first insert, and a fixing protrusion is fixed on the bottom surface of the second insert. When the moving wheel protrudes from the installation groove, the fixing protrusion moves down synchronously with the second insert, and the lower end of the fixing protrusion abuts against the upper side of the positioning rod at this time.

[0023] By adopting the above technical solution, when the meter box needs to be moved, i.e., when the moving wheels protrude from the mounting groove, the fixing protrusion on the bottom of the second insertion rod will move down synchronously and abut against the upper side of the positioning rod. This design effectively prevents the meter box from shaking or shifting due to uneven force or uneven road surface during movement, ensuring the stability and safety of the movement.

[0024] Optionally, the wiring hole on the housing is located between the adjusting plate and the positioning protrusion. The upper side of the positioning protrusion is provided with a first sealing notch, and the bottom surface of the adjusting plate is provided with a second sealing notch when the first protrusion is inserted into the first groove. An elastic sealing strip is fixed on the inner wall of the first sealing notch and the second sealing notch.

[0025] By adopting the above technical solution, when the first protrusion of the adjusting plate is engaged with the first groove, placing the meter box in a stable installation state, the second sealing notch on the bottom surface of the adjusting plate corresponds to the first sealing notch on the upper side of the positioning protrusion. The elastic sealing strips within them press against each other, forming a tight sealing barrier. This effectively prevents rainwater, dust, and other impurities from entering the box from around the wiring holes, avoiding damage to the electrical components inside and extending the service life of the meter box. Furthermore, this sealing design requires no additional complex structure, is low-cost, and easy to install. Without affecting the normal height adjustment and movement functions of the meter box, it provides reliable protection for the internal components, improving the operational stability and safety of the meter box in complex outdoor environments.

[0026] In summary, this application includes the following beneficial technical effects: This distribution box utilizes the rotation of an adjusting plate to drive the first and second insert rods to slide towards or away from each other via a linkage. When the first and second protrusions respectively engage with the first and second grooves, a stable connection is achieved between the box body and the base plate. To adjust the height, simply reverse the adjustment plate to disengage the protrusions from their grooves, allowing the box body to slide back and forth on the base plate. Once the desired height is selected, the protrusions are re-engaged into their corresponding grooves. The entire process is simple to operate, significantly saving manpower and time, improving adjustment efficiency, reducing adjustment costs, and avoiding damage to the wall structure from repeated drilling. It better meets the need for flexible installation height adjustments in practical applications. Attached Figure Description

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] Example: Reference Figure 1 and Figure 2 An outdoor meter box includes a base plate 1 fixed to a wall, a box body 2 mounted on the base plate 1, and a door 3 mounted on the box body 2. The box body 2 has wiring holes 21 for external cables to be connected on two opposite vertical sides. One side edge of the door 3 is rotatably connected to the vertical opening of the box body 2, and the other side edge of the door 3 is detachably connected to the box body 2 by a conventional locking structure. An adjustment component 4 is provided on the opposite vertical sides of the box body 2, which can be used to adjust and lock the installation position of the box body 2 on the base plate 1.

[0032] Reference Figure 2 The adjustment component 4 includes an adjustment plate 41 rotatably mounted on two opposite vertical sides of the housing 2. A first insert rod 42 and a second insert rod 43 are slidably arranged vertically along the horizontal direction on the two opposite vertical sides of the housing 2, and the second insert rod 43 is located below the first insert rod 42. A linkage component 44 is provided on the outside of the housing 2. The end of the first insertion rod 42 away from the door 3 is fixed with a first protrusion 421 facing the second insertion rod 43, and the second insertion rod 43 is fixed with a second protrusion 431 facing the first protrusion 421. The base plate 1 is provided with a plurality of first slots 11 for the first insertion rod 42 to be inserted and slide up and down, and second slots 12 for the second insertion rod 43 to be inserted and slide up and down. The inner walls of the first slot 11 and the second slot 12 are respectively provided with a first groove 111 and a second groove 121. When the adjusting plate 41 rotates, it drives the first insert rod 42 and the second insert rod 43 to slide towards and away from each other through the linkage 44. When the first insert rod 42 and the second insert rod 43 slide towards each other, the first protrusion 421 and the second protrusion 431 respectively get into the first groove 111 and the second groove 121. When the first insert rod 42 and the second insert rod 43 slide away from each other, the first protrusion 421 and the second protrusion 431 respectively get out of the first groove 111 and the second groove 121.

[0033] Reference Figure 3 The adjusting plate 41 is fixed with a rotating shaft 411 that is rotatably connected to the vertical outer side of the housing 2. The adjusting plate 41 can reciprocate around the rotating shaft 411. The rotating surface of the adjusting plate 41 is parallel to the vertical surface of the housing 2 where the rotating shaft 411 is located. The outside of the housing 2 is provided with a locking member 45 to limit the rotation state of the adjusting plate 41. The adjusting plate 41 has a locking through hole, and the outer side of the housing 2 has a locking thread groove that can coincide with the locking through hole. The locking part 45 is specifically a locking bolt 451 that passes through the locking through hole and is screwed into the locking thread hole. The locking bolt 451 is a wing bolt that can be manually tightened.

[0034] Reference Figure 2 The linkage 44 includes a first bending rod 441 vertically fixed to the end of the first insert rod 42 away from the substrate 1, and a second bending rod 442 of the second insert rod 43 away from the end of the substrate 1. The first bending rod 441 and the second bending rod 442 are bent in a direction that approaches each other. The linkage rod 443 is slidably provided on the vertical outer surface of the housing 2 in the horizontal direction. A first guide block 22 is fixed on the outer side of the housing 2 to limit the sliding of the linkage rod 443. A second guide block 24 is also fixed on the outer side of the housing 2 to limit the up and down sliding of the first bending rod 441 and the second bending rod 442. A guide through hole is provided on the first guide block 22 for the linkage rod 443 to pass through and slide. Two connecting rods 445 are rotatably connected to the end of the linkage rod 443 away from the box door 3. The ends of the first folding rod 441 and the second folding rod 442 are rotatably connected to the other ends of the two connecting rods 445 respectively. An adjusting rod 444 is rotatably connected to the outer periphery of the adjusting plate 41. The other end of the adjusting rod 444 is rotatably connected to the end of the linkage rod 443 away from the base plate 1. When the adjusting plate 41 rotates, the linkage rod 443 can slide back and forth in the horizontal direction under the traction of the adjusting rod 444, so that the first insert rod 42 and the second insert rod 43 slide towards and away from each other.

[0035] Reference Figure 4 and Figure 5The lower part of the two opposite vertical sides of the housing 2 is integrally formed with an extension plate 23. The extension plate 23 has two mounting through holes 231. The housing 2 is provided with a moving component 5, which includes a support vertical rod 51 that passes through the mounting through hole 231 and a moving wheel 52 installed on the lower end face of the support vertical rod 51. The lower edge of the opening of the mounting through hole 231 is provided with a mounting groove 232 for the moving wheel 52 to be inserted. The inner wall of the mounting through hole 231 is provided with a reset part 53 that drives the moving wheel 52 to move upward. The adjusting plate 41 is provided with a positioning part 54 that drives the moving wheel 52 to move downward. When the meter box needs to be moved a short distance, the adjusting plate 41 is rotated in advance to adjust the first protrusion 421 to disengage from the first groove 111. At this time, the adjusting plate 41 drives the support rod 51 to move downward through the positioning member 54 and protrude from the mounting groove 232. When the meter box is installed and used, the first protrusion 421 is adjusted to be inserted into the first groove 111. At this time, the positioning member 54 stops pressing on the support rod 51. Then, under the action of the reset member 53, the moving wheel 52 moves up into the mounting groove 232 for storage.

[0036] Reference Figure 5 and Figure 6 The positioning component 54 includes a positioning protrusion 541 fixed on the outer periphery of the adjusting plate 41, a positioning rod 542 horizontally disposed above the extension protrusion 23, and a positioning protrusion 543 fixed on the upper side of the positioning rod 542. The outer periphery of the positioning protrusion 541 away from the adjusting plate 41 is a guide slope 5411. The upper end faces of the two supporting vertical rods 51 on the same side are fixedly connected to the lower side of the positioning rod 542; when the positioning convex plate 541 rotates with the adjusting plate 41 to the vertical downward state, it is located directly above the positioning convex block 543. At this time, the positioning convex plate 541 presses against the positioning convex block 543, causing the supporting vertical rod 51 to move downward.

[0037] Reference Figure 6 A fixing protrusion 46 is fixed on the bottom surface of the second insert rod 43. When the moving wheel 52 protrudes from the mounting groove 232, the fixing protrusion 46 moves downward synchronously with the second insert rod 43. At this time, the lower end of the fixing protrusion 46 abuts against the upper side of the positioning rod 542 to maintain the stability of the moving wheel 52 when it protrudes.

[0038] Reference Figure 7 A limiting baffle 511 is fixedly provided on the outer periphery of the supporting vertical rod 51. A clearance groove 233 is provided on the upper edge of the opening of the mounting through hole 231 for the limiting baffle 511 to be inserted and slide. The reset member 53 includes a reset spring 531 whose two ends are fixedly connected to the bottom side of the clearance groove 233 and the bottom surface of the limiting baffle 511, respectively. The reset spring 531 is in a compressed state.

[0039] Reference Figure 8 and Figure 9The wiring hole 21 on the housing 2 is located between the adjusting plate 41 and the positioning protrusion 543. The upper side of the positioning protrusion 543 is provided with a first sealing notch 5431. The bottom surface of the adjusting plate 41 when the first protrusion 421 is inserted into the first groove 111 is provided with a second sealing notch 412. The inner walls of the first sealing notch 5431 and the second sealing notch 412 are fixed with elastic sealing strips 55 made of rubber. After the meter box is installed and the cable is connected to the box 2 through the wiring hole 21, the moving wheel 52 is stored in the mounting groove 232, and the first protrusion 421 is inserted into the first groove 111. The first sealing notch 5431 and the second sealing notch 412 are together surrounding the outer periphery of the external cable, and the elastic sealing strip 55 presses against the outer periphery of the external cable, thereby reducing the possibility of external dust or other impurities entering the box 2 through the wiring hole 21.

[0040] The implementation principle of this application embodiment is as follows: In terms of installation and adjustment, rotating the adjustment plate 41 causes the first insertion rod 42 and the second insertion rod 43 to slide towards or away from each other via the linkage 44. When sliding towards each other, the first protrusion 421 and the second protrusion 431 respectively engage with the first groove 111 and the second groove 121, thereby locking the position of the housing 2 on the base plate 1. When sliding away from each other, the housing 2 can be disengaged and its position can be adjusted. The rotating surface of the adjustment plate 41 is parallel to the vertical surface of the housing 2 where the rotating shaft 411 is located. The locking bolt 451 passes through the locking through hole and is screwed into the locking thread groove, which can limit the rotation state of the adjustment plate 41.

[0041] In terms of movement and storage, when moving the meter box over a short distance, rotating the adjusting plate 41 causes the first protrusion 421 to disengage from the first groove 111. The adjusting plate 41 then moves the supporting vertical rod 51 downward through the positioning member 54, and the moving wheel 52 protrudes from the mounting recess 232 for easy movement. During installation and application, rotating the adjusting plate 41 causes the first protrusion 421 to engage with the first groove 111. The positioning member 54 stops pressing the supporting vertical rod 51, and the reset spring 531 pushes the limit baffle 511, causing the moving wheel 52 to move upward to the mounting recess 232 for storage.

[0042] In terms of sealing, after the meter box is installed and the cable is connected, the moving wheel 52 is stored, the first protrusion 421 is inserted into the first groove 111, the first sealing notch 5431 and the second sealing notch 412 are together surrounding the outer periphery of the cable, and the elastic sealing strip 55 presses against the outer periphery of the cable to reduce the possibility of external dust or impurities entering the box 2 through the wiring hole 21.
