Description

Technical Field

[0001] The invention relates to the technical field of outdoor electric meter box equipment, and in particular to an outdoor electric meter box which is easy to install and maintain. Background Art

[0002] Outdoor meter boxes or outdoor power boxes are usually used for electricity metering and power distribution control in public facilities, commercial buildings, residential areas, industrial areas and other places, and protect against overload, short circuit and leakage of lines to ensure the safe and stable operation of the power system. Common installation methods include stand-up and wall-mounted. In some cases where the installation space is relatively cramped, or decorative greening facilities are arranged around the outer periphery of the box, the existing outdoor meter boxes or outdoor power boxes, such as an outdoor waterproof meter box disclosed in Chinese patent document CN115395374A, have a box door in the form of a conventional single-door or double-door opening and closing door, which is not convenient to open completely, and is therefore not conducive to convenient installation. In addition, in rainy and snowy weather, if installation and maintenance operations are required, the existing conventional single-door or double-door opening and closing door forms cannot play a good role in preventing rain and snow. In this regard, in an outdoor waterproof meter box disclosed in CN115395374A, rain sensors and water level sensors are respectively fixed on the upper and lower sides of the mounting platform of the box. When there is too much water on the ground, the meter box can be lifted to a high place, and a rain cover is fixed on the top of the box. However, the additional rainproof device has too high a modification cost for the original box and is complicated to operate, and it cannot meet the current outdoor meter box or outdoor power box. Convenient and safe installation and maintenance operations with higher practicality. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide an outdoor meter box that is easy to install and maintain, so as to solve the problem that the existing outdoor meter box is not convenient and safe enough for installation and maintenance operations in rainy and snowy weather due to the cramped space outside the box.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig.10As shown, an outdoor electric meter box which is easy to install and maintain comprises a box body 1, a switch door 2 is provided at the front end of the box body 1, a vertical slide groove 3 is provided on the inner side wall of the box body 1, the top end of the slide groove 3 is open, a through hole 4 which passes through the outside of the box body 1 is provided at the top of the slide groove 3, and two groups of through holes 4 are provided adjacent to each other up and down, a rainproof cloth 5 is connected to the outer top end of the box body 1, a notch 6 is provided at the front end of the top wall of the box body 1, convex strips 21 are provided on the side ends of the switch door 2 along the length direction thereof, and a spring column 22 is provided on the side end of the switch door 2 below the convex strip 21, and when the switch door 2 is in the initial state of closing the front end of the box body 1, the convex strip 21 and the spring column 22 are in the closed state. Inserted in the slide groove 3, one end of the rainproof cloth 5 penetrates into the box body 1 along the notch 6 and is connected to the side of the switch door 2 facing the box body 1. When the switch door 2 moves up along the notch 6 to open, the convex strip 21 and the elastic column 22 move up synchronously along the slide groove 3 until the elastic column 22 slides to the lower through-hole 4 and bounces out along the lower through-hole 4. The bottom end of the convex strip 21 is located at the top of the slide groove 3, and continues to move up with the switch door 2 until the elastic column 22 slides to the upper through-hole 4, the elastic column 22 bounces out along the upper through-hole 4, the convex strip 21 completely slides out along the top opening of the slide groove 3, the switch door 2 rotates and tilts forward toward the front end of the box body 1, and pulls the rainproof cloth 5 to tighten.

[0037] The present invention is based on the basic structure of the existing outdoor electric meter box or outdoor electric energy box, including a box body 1, a switch door 2 is provided at the front end of the box body 1, and in particular, a vertical slide groove 3 is provided on the inner side wall of the box body 1, the top of the slide groove 3 is an opening, and a through hole 4 is provided on the top of the slide groove 3 to penetrate out of the box body 1, and two groups of through holes 4 are arranged adjacent to each other up and down, that is, two through holes 4 are provided on the top of the slide groove 3 on one side, and the slide grooves 3 on both sides are symmetrically arranged, with a total of four through holes 4. A rainproof cloth 5 is connected to the outer top of the box body 1, and the rainproof cloth 5 can adopt the existing widely used for covering, A flexible cloth with lightness, durability and rainproof effect for outdoor use. A notch 6 is provided at the front end of the top wall of the box body 1 for the door 2 to slide up and down. The side ends of the door 2 are provided with convex strips 21 along the length direction. The side ends of the door 2 are provided with elastic columns 22 at the positions below the convex strips 21. The elastic columns 22 can adopt existing conventional structural components such as elastic telescopic rods. The fixed end of the elastic column 22 is fixedly embedded in the door 2, and the movable end of the elastic column 22 is passed through and abutted against the inner side of the slide groove 3. When the door 2 is in the initial state of closing the front end of the box body 1, as shown in FIG. Figure 1 , Figure 2 As shown, the convex strip 21 and the elastic column 22 are inserted into the slide groove 3 to ensure that the switch door 2 is stably closed at the front end of the box body 1. At this time, one end of the rainproof cloth 5 penetrates into the box body 1 along the notch 6 and is connected to the side of the switch door 2 facing the box body 1. When the switch door 2 moves up along the notch 6 to open, the convex strip 21 and the elastic column 22 move up along the slide groove 3 synchronously until the elastic column 22 slides to the lower through-hole 4 and pops out along the lower through-hole 4. Figure 6 , Figure 7As shown, at this time, the bottom end of the convex strip 21 is located at the top of the slide groove 3. Through the limitation of the convex strip 21 and the spring column 22, the switch door 2 is in a vertically fully opened state. For the space outside the box body 1 is relatively cramped, such as a narrow area such as an aisle, or when greening is arranged on the periphery, maintenance facilities are stacked, etc., the switch door 2 of the vertical switch is convenient to be fully opened. In addition, especially for areas with more rainfall, when encountering rainy and snowy weather, by pressing the spring column 22, the switch door 2 continues to move upward until the spring column 22 slides to the upper through-hole 4, and the spring column 22 pops out along the upper through-hole 4. Figure 8 , Fig. 9 , Fig.10 As shown, at this time, the convex strip 21 completely slides out along the top opening of the slide groove 3, and the elastic column 22 can rotate freely along the through-hole 4, so that the switch door 2 rotates and tilts forward toward the front end of the box body 1, and pulls the rainproof cloth 5 to be tensioned. One end of the rainproof cloth 5 is connected to the outer top of the box body 1, and the other end is connected to the side of the switch door 2 facing the inside of the box body 1. On the one hand, it plays a role in tightening the switch door 2 that rotates and tilts forward, and stabilizes the switch door 2 in a limited position. On the other hand, it plays a role in rainproofing. Rainwater flows down along the inclined switch door 2 and the rainproof cloth 5, and flows outward along the top of the box body 1, avoiding part of the rainwater from leaking into the box body 1 along the notch 6, thereby achieving a better rainproof effect. Therefore, when only the switch form of the switch door 2 is improved, there is no need to add an additional rainproof device, and the switch door 2 in the lower position can be used. When the opening 4 is limited and fixed, it is completely opened vertically and does not occupy the outer space of the box body 1. When the switch door 2 is limited at the upper opening 4, it is tightened by the rainproof cloth 5 to keep the switch door 2 in a rotating forward tilted state, which plays a good rainproof role and does not occupy the outer space of the box body 1. Thereby, further convenient and safe installation and maintenance operations in multiple scenarios are achieved. In production, it is only necessary to improve the switching form of the switch door 2 and connect the rainproof cloth 5. For the used box body 1, the original front door can be removed, and the above switch door 2 and the matching front side panel components can be replaced, and the rainproof cloth 5 can be connected. It has high practicality and is suitable for most existing outdoor meter boxes, power boxes, switch boxes, distribution boxes and other power equipment, and is equally applicable whether it is a stand-alone or wall-mounted type.

[0038] In an embodiment of the present invention, Figure 1 , Fig.11 , Fig.12 , Fig.13 As shown, a limit seat 7 is provided on the box body 1 at the outer side of the through-opening 4. The limit seat 7 is a hollow structure. When the elastic column 22 is ejected outward, the outer end of the elastic column 22 is inserted into the limit seat 7 and rotates along the limit seat 7. The outer end of the limit seat 7 is connected with a limit column 8, and the limit column 8 is pushed inward to close the through-opening 4.

[0039] Specifically, Fig.11 , Fig.12 , Fig.13As shown, a limiting hole 71 is provided on the outer wall of the limiting seat 7, and two groups of limiting holes 71 are spaced apart along the length direction of the limiting seat 7. A turntable 72 is connected to the outer end of the limiting column 8 that passes through the limiting seat 7. A limiting rod 73 is rotatably connected to the turntable 72. One end of the limiting rod 73 is connected to a limiting block 74, and an elastic component such as a spring is connected between the other end and the outer side of the limiting seat 7 for elastically pushing the limiting rod 73 to rotate horizontally so that the limiting block 74 is inserted into the limiting hole 71 for limiting. More preferably, the turntable 72 and the limiting rod 73 are symmetrically arranged at the upper and lower ends of the outer side of the limiting seat 7. When in use, the limiting column 8 is held by hand and the outer end of the limiting rod 73 is naturally pressed. Fig.13 As shown, the limiting rod 73 is driven to rotate, overcoming the elastic force of the elastic component so that the limiting block 74 moves out of the limiting hole 71. At this time, the limiting column 8 can be pushed or pulled to move horizontally. By pulling the limiting column 8 outward, as shown in FIG. Fig.11 As shown, when the limit block 74 is inserted into the limit hole 71 at the outer end, the limit seat 7 is in an empty state, so that the elastic column 22 can be inserted and inserted. By pushing the limit column 8 inward, as shown in FIG. Fig.12 As shown, when the limiting block 74 is inserted into the limiting hole 71 at the inner end, one end of the limiting column 8 is in a closed penetration state, and the elastic column 22 cannot be ejected outward.

[0040] Among them, when the switch door 2 is in the initial state at the front end of the closed box body 1, the upper and lower limit blocks 74 can be kept inserted into the limit holes 71 at the inner end. At this time, no matter how the switch door 2 is lifted, the elastic column 22 cannot be limited outward, that is, the switch door 2 cannot be fixed to a limit, thereby preventing non-maintenance staff from misoperating the switch door 2. When the installation and maintenance staff are working, they can operate to make only the lower limit column 8 in a pulled-out state, which is used to push the switch door 2 up to make it in a vertically fully open state. In rainy and snowy weather, they can operate to make only the upper limit column 8 in a pulled-out state, which is used to push the switch door 2 up to make it in a rotated forward tilted state.

[0041] Optional, such as Fig.11 , Fig.12 , Fig.13 , Fig.14 As shown, a plurality of elastic protrusions 75 are convexly provided on the inner side wall of the upper limit seat 7, and a plurality of elastic protrusions 75 are arranged along the length direction of the limit seat 7. A groove 220 is opened on the outer side wall of the elastic column 22 along its axial direction. When the elastic column 22 is ejected outward, the groove 220 moves laterally along the arrangement direction of the elastic protrusions 75, so that the elastic protrusions 75 penetrate into the groove 220. When the elastic column 22 rotates freely in the limit seat 7, it plays a certain damping role. In addition, optionally, an anti-slip surface layer can also be provided on the inner side wall of the upper limit seat 7, which also plays a damping role and is conducive to the gentle rotation of the door 2. The anti-slip surface layer and the elastic protrusions 75 can adopt existing conventional structural designs such as rubber particles.

[0042] In an embodiment of the present invention, Figure 1 , Figure 2 As shown, a first sealing strip 9 is provided at the top of one side of the switch door 2 facing the box body 1. When the switch door 2 is in the initial state of closing the front end of the box body 1, the first sealing strip 9 is pressed against the rainproof cloth 5 at the notch 6 to prevent rainwater from seeping into the box along the gap at the notch 6 when the switch door 2 is closed.

[0043] As another embodiment of the present invention, Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, one end of the rainproof cloth 5 away from the switch door 2 penetrates into the box along the top of the box body 1 and is connected to a second sealing strip 10. The bottom end of the second sealing strip 10 is connected to an inner handle 11. When the switch door 2 is in the initial state of closing the front end of the box body 1 and when the switch door 2 rotates and tilts forward toward the front end of the box body 1, the rainproof cloth 5 is in a tensioned state so that the second sealing strip 10 presses against the inner top wall of the box body 1. In this way, the second sealing strip 10 is used to press and seal the seam of the rainproof cloth 5 that penetrates the top of the switch door 2. When the installation and maintenance construction is completed in rainy and snowy weather, the inner handle 11 is pulled down to pull the rainproof cloth 5, so that the switch door 2 that has rotated and tilted forward is rotated back to an upright state, and then the switch door 2 is moved down to close, which further facilitates the operation.

[0044] In an embodiment of the present invention, optionally, Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a vertical bottom plate 12 is installed on the side of the switch door 2 facing away from the box body 1. Specifically, the bottom plate 12 is designed as a thin plate and can be selectively installed on the outer facade of the switch door 2 by bolts, and is symmetrically installed on both sides of the bottom of the switch door 2. A vertical connecting plate 13 is provided in parallel on the outer side of the bottom plate 12. The vertical connecting plate 13 is also designed as a thin plate. An inner reel 14 is provided in parallel on the outer side of the vertical connecting plate 13. The bottom end of the vertical connecting plate 13 is rotatably connected to the bottom end of the bottom plate 12. A first rainproof film 15 is connected between the vertical connecting plate 13 and the bottom plate 12. A second rainproof film 16 is wound in the inner reel 14. The inner reel 14 A side opening is provided on the side facing the vertical connecting plate 13. Specifically, the inner drum 14 is designed as a hollow structure. A reel is connected to the inner center of the inner drum 14 along its axial rotation, and an elastic component such as a torsion spring can be provided at the rotation connection to drive the second rainproof film 16 to be wound on the reel. The outer end of the second rainproof film 16 passes through the side opening and is connected to the vertical connecting plate 13. The first rainproof film 15 and the second rainproof film 16 can be made of flexible materials such as existing conventional rainproof films. More preferably, a magnetic block 17 is provided at the top of the vertical connecting plate 13. When the switch door 2 is in the initial state at the front end of the closed box body 1, as shown in FIG. Figure 1As shown, or in the vertically opened state, such as Figure 6 , Figure 7 As shown, the vertical connecting plates 13 are all adsorbed on the top of the bottom plate 12 through the magnetic block 17, and the magnetic block 17 also helps to adsorb the inner reel 14. When the switch door 2 rotates and tilts forward toward the front end of the box body 1, as shown in FIG. Figure 8 , Fig. 9 As shown, under the influence of its own weight, the vertical connecting plate 13 breaks away from the magnetic attraction of the magnetic block 17 and rotates downward to a horizontal state, so that the first rainproof film 15 is unfolded in a fan shape, and the second rainproof film 16 is shielded on both sides of the box body by pulling down the inner roller 14, thereby achieving a better rainproof effect and facilitating further convenient and safe installation and maintenance operations.

[0045] In an embodiment of the present invention, Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a telescopic pin 18 is provided at the inner end of the inner drum 14. Specifically, the telescopic pin 18 can adopt existing conventional pull pins, spring telescopic pins and other components. The fixed end of the telescopic pin 18 is fixed to the inner side of the bottom end of the inner drum 14. The movable telescopic direction of the telescopic pin 18 is parallel to the length direction of the inner drum 14. When the second rainproof film 16 is unfolded to cover the outer sides of the box body 1, the telescopic pin 18 is pulled out to make the telescopic pin 18 inserted into the inner end of the box body 1. More preferably, a plug ring can be correspondingly provided at the inner end of the box body 1 for the telescopic pin 18 to be plugged and fixed, so as to fix the position of the inner drum 14, which is conducive to further convenient and safe installation and maintenance operations.

[0046] As another embodiment of the present invention, a accommodating bin may be provided at the bottom end of the box body 1, and the inner reel 14 is not connected to the outer side of the vertical connecting plate 13, but is stored in the accommodating bin. In rainy and snowy weather, the inner reel 14 is pulled out horizontally, and then the second rainproof film 16 in the inner reel 14 is pulled out and unfolded, and the pulled-out end of the second rainproof film 16 is connected to the upper horizontal vertical connecting plate 13. The connection method may be conventional existing methods such as Velcro, snaps, etc., so as to achieve shielding on both sides outside the box body 1 while facilitating the hidden storage and protection of the inner reel 14 and the second rainproof film 16.

[0047] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a door handle 19 is installed at the bottom of the side of the switch door 2 facing away from the box body 1.
