Description

Technical Field

[0001] The present application relates to the technical field of metering boxes, and in particular to a metering box with high protection performance and foamed rubber. Background Art

[0002] In the modern power and energy management sector, wall-mounted double-door meter boxes are critical equipment, widely used in various locations for precise metering and monitoring of electricity and other energy sources. They not only bear the crucial responsibility of accurately recording energy usage data but also play a crucial role in the efficiency and safety of energy management. With the continuous advancement of technology and the increasing complexity of application scenarios, the performance requirements for wall-mounted double-door meter boxes are also increasing. Sealing and waterproofing are key indicators of their quality. Good sealing and waterproofing effectively protect internal components, extend the service life of the meter box, and ensure stable and reliable operation.

[0003] In the related art, an outdoor meter box is mainly composed of a box body and two box doors hinged on the box body; in terms of sealing design, the inner wall of the box door is fixed with a sealing strip by glue or tape, and the outer edge of the box opening is fixed with an annular convex plate; when the box door is closed, the annular convex plate is tightly abutted against the sealing strip to form a sealing barrier, which effectively prevents external moisture, dust, etc. from entering the interior of the box, thereby ensuring the sealing and waterproof performance of the meter box; in actual installation, for the meter box installed on an outdoor utility pole, an arc clamp is usually fixed on the utility pole in advance as a mounting base, and then the box body is fixed to the arc clamp with screws.

[0004] In the aforementioned related technologies, due to the high installation height of the meter box, installers lack a foothold during operation. Once the through-holes in the curved clamps align with those in the box, the box easily wobbles, making precise positioning and securing difficult. Even after initial alignment, the box may become misaligned or misaligned again during subsequent securing. Installers then have to spend a significant amount of time repeating the alignment operation, which not only increases the difficulty of installation but also significantly reduces overall installation efficiency, leaving room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a meter box with high protection performance and foam rubber, so as to solve the problem in the above-mentioned related art that the installation of the meter box on the utility pole takes a long time and the overall efficiency is low.

[0006] The present application provides a high-protection metering box with foam rubber, which adopts the following technical solution: A metering box with high protection performance and foam rubber comprises a box body, two box doors hinged relative to each other on the box body, a plurality of heat dissipation holes are provided on the two opposite side walls of the box body, and a protective plate for protecting the heat dissipation holes is installed on the outside of the box body; two mutually parallel fixing plates are vertically installed on the side of the box body away from the box door, an arc-shaped notch is provided on the side of the fixing plate away from the box body, a flexible fixing rope is detachably installed on the outside of the fixing plate, and the flexible fixing rope and the arc-shaped notch on the fixing plate are jointly arranged on the outer periphery of the electric pole.

[0007] By adopting this technical solution, when installing the meter box on a utility pole, the flexible fixing rope and the curved notch on the fixing plate are placed around the outer circumference of the pole, pre-locking the meter box. This provides a foothold for the installer, greatly reducing the possibility of the box shifting or misaligning when further screws are used to secure it. This eliminates the need for time-consuming, repetitive alignment operations, avoiding installation difficulties caused by box sway, tilt, or misalignment, significantly reducing installation time and improving overall efficiency.

[0008] Optionally, one end of the flexible fixing rope is fixedly connected to one end of the arc-shaped notch, the other end of the flexible fixing rope is fixedly provided with a hook, and the other end edge of the arc-shaped notch is fixedly provided with a snap ring for the hook to be engaged with.

[0009] By adopting this technical solution, the hook and ring design allows for quick and convenient connection of the flexible fixing rope to the fixing plate when mounting the meter box on a utility pole, forming a structure that surrounds the pole and pre-locks the meter box. Compared to other complex connection methods, this design is simple to operate and can be easily completed by the installer, saving installation time.

[0010] Optionally, the side of the fixing plate away from the arc-shaped notch is rotatably connected to the outer side surface of the box, and the two fixing plates can be rotated to an installation state parallel to each other, and to a storage state in contact with the side of the box away from the door; the protective plate is slidably arranged on the outer side surface of the box, and the protective plate can slide back and forth in a direction close to the fixed plate, and the protective plate is provided with a locking member for fixing the fixed plates in different states.

[0011] By adopting the above technical solution, during transportation, the two fixed plates are rotated to a storage state in which they are in contact with the side of the box body away from the door, which reduces space occupancy, facilitates the packaging and transportation of the meter box, and reduces transportation costs and difficulty. At the same time, the protective plate is slid close to the fixed plate, and the fixed plate in the storage state is fixed by a locking member to avoid damage caused by shaking of the fixed plate during transportation. During installation, the fixed plates are rotated to an installation state parallel to each other, the protective plates are slid close to the fixed plates, and the fixed plates in the installation state are locked with the help of locking members to ensure the stability of the fixed plates during installation, which facilitates the subsequent use of flexible fixing ropes and arc-shaped notches to surround the poles for pre-locking. This design of a rotatable fixed plate and a sliding protective plate in conjunction with a locking member allows the meter box to flexibly adjust its state according to different scenarios, taking into account both the convenience of transportation and the stability of installation, and improving the overall performance and user experience of the product.

[0012] Optionally, an accommodating groove for embedding the flexible fixing rope is provided on the inner wall of the arc-shaped notch.

[0013] By adopting the above technical solution, during the transportation process, after the fixing plate is pre-rotated to a storage state that fits the outer side of the box, the flexible fixing rope can be embedded in the storage groove on the inner wall of the arc-shaped notch. This design cleverly solves the problem of the flexible fixing rope having nowhere to be placed and being easy to shake during transportation, making the overall structure of the meter box more regular, and effectively preventing the flexible fixing rope from colliding with or scratching the box or other components due to random swinging during transportation, thereby causing damage to the flexible fixing rope or the box, thereby ensuring the integrity of the meter box during transportation. During the installation stage, when the meter box is transported to the installation site in the storage state, the flexible fixing rope has been neatly stored in the storage groove, without the need for additional organization. The installer can directly proceed with subsequent operations, which improves installation efficiency.

[0014] Optionally, two first slide rails are fixedly arranged side by side in a horizontal direction on the outer side surface of the box body, and guide protrusions are fixedly provided on the side opposite edges of the protective plate facing the box body, and guide grooves are formed on the guide protrusions for the first slide rails to be inserted and slide; the locking member includes second slide rails fixedly arranged on the opposite edges of the fixed plate, and the two first slide rails can be in a coaxial state with the two second slide rails when the two fixed plates are rotated to a horizontal state, and the protective plate can slide in a direction close to the second slide rails to make the second slide rails slide into the guide grooves.

[0015] By adopting the above technical solution, when installing the meter box, the fixed plate is rotated to a horizontal position. At this time, the two first slide rails are coaxial with the second slide rails on the edges of the two fixed plates. The protective plate slides along the first slide rails through the guide grooves on the guide protrusions, approaching the fixed plate, allowing the second slide rails to slide smoothly into the guide grooves. This design achieves precise locking of the fixed plate in the installed state, preventing the fixed plate from shaking or shifting during subsequent installation, ensuring the stability of the meter box installation, and providing reliable support for subsequent operations such as pre-locking the flexible fixing rope and the arc-shaped notch around the utility pole and screw fixing, reducing installation difficulty and improving installation efficiency.

[0016] Optionally, the locking member includes two positioning rods fixed on the side of the protective plate close to the fixed plate, and a positioning slot is provided on the second slide rail; the two second slide rails can be rotated downward to a vertical state along with the two fixed plates, and the positioning rods can slide toward the fixed plate along with the protective plate and be inserted into the positioning slot in this state.

[0017] By adopting this technical solution, when the meter box is in a storage state, such as when it is being transported or not installed, the two fixing plates are rotated downward to a vertical position. The protective plate then slides toward the fixing plate, and the two positioning rods fixed to it precisely insert into the positioning slots provided on the second slide rail. This design effectively secures the fixing plate in the storage state, preventing the fixing plate from colliding with the box body or other components due to shaking during transportation, protecting the fixing plate and the entire meter box structure from damage, and extending the product's service life.

[0018] Optionally, an elastic clamping member is provided on the inner wall of the guide slide groove, and a plurality of positioning grooves for the elastic clamping member to be clamped into are provided on the first slide rail and the second slide rail.

[0019] By adopting the above technical solution, during the sliding process of the protective plate along the first and second slide rails, the elastic clips on the inner wall of the guide groove will cooperate with the positioning grooves on the first and second slide rails. When the protective plate slides to the appropriate position, such as when the fixed plate in the installed state is locked or the fixed plate in the stored state is fixed, the elastic clips are snapped into the corresponding positioning grooves, making a clear "click" sound, giving the installer clear feedback on the position, making it easier to quickly determine whether the protective plate has reached the correct position, and improving installation efficiency. At the same time, the snap-fit structure between the elastic clips and the positioning grooves can effectively prevent the protective plate from accidentally sliding when subjected to slight external forces, ensuring the stability of the fixed plate in the installed or stored state, and avoiding the loosening of the fixed plate due to the displacement of the protective plate, thereby affecting the installation quality or transportation safety of the metering box.

[0020] Optionally, a locking rod is provided on the inner wall of the box body and is slidable in the horizontal direction. A locking protrusion is fixed on the side of the locking rod facing the box door, and an elastic extrusion part is provided on the inner wall of the box body to drive the locking rod to slide toward the box door; a locking block is fixed on the inner side surface of the box door, and a locking slot for inserting the locking protrusion is provided on the locking block; an extension rod is fixed on the outer periphery of the locking rod, and a guide groove for the extension rod to pass through and slide is provided on the inner wall of the box body, and a control part is provided on the protective plate to drive the extension rod to slide in the away direction.

[0021] By adopting the above technical solution, when the door is closed, the elastic extrusion member pushes the locking rod to slide toward the door, so that the locking protrusion on the locking rod is inserted into the locking slot on the locking block on the inner side of the door, thereby realizing automatic locking of the door, preventing the door from opening accidentally, ensuring the safety of the internal components of the metering box, and avoiding damage to the internal components or data loss due to the opening of the door. At the same time, this locking method is easy to operate and the door can be locked without additional manual operation. When the door needs to be opened, the control member on the protective plate drives the extension rod to slide in the guide groove, thereby causing the locking rod to slide away from the door, and the locking protrusion disengages from the locking slot, releasing the lock on the door, making it easier for the installer to operate.

[0022] Optionally, a locking through hole is provided on the protective plate, and a locking screw hole that can overlap with the locking through hole is provided on the outer end of the extension rod. The control part is a locking screw located outside the protective plate, and the locking screw can pass through the locking through hole and then be screwed into the corresponding locking screw hole.

[0023] By adopting the above technical solution, a detachable connection between the protective plate and the extension rod is achieved, which makes it convenient for subsequent staff to slide the locking rod away from the door by sliding the protective plate.

[0024] Optionally, a sealing strip made of a foaming agent material is fixedly provided on the inner side surface of the door, and a sealing frame is fixedly provided on the outer edge of the door opening, and the sealing strip can be pressed tightly against the sealing frame when the door is closed.

[0025] By adopting the above technical solution, when the box door is closed, it can tightly press against the sealing frame fixed around the outer edge of the box door opening, effectively filling the gap between the box door and the box body, preventing external dust, moisture, rainwater, etc. from invading the interior of the meter box, protecting internal electrical components from erosion by environmental factors, reducing the risk of component failure caused by moisture, dust accumulation, etc., and extending the service life of the meter box.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When mounting the meter box on a utility pole, place the flexible fixing rope and the curved notch on the fixing plate around the pole to pre-lock the meter box. This provides a foothold for the installer, significantly reducing the possibility of the box shifting or misaligning when further screws are used to secure it.

[0027] 2. During transportation, rotate the two fixing plates to a storage position that aligns with the sides of the box away from the door. This reduces space usage, facilitates packaging and transportation of the meter box, and reduces transportation costs and difficulty. At the same time, slide the protective plate closer to the fixing plates and secure them in the storage position with the locking member to prevent damage caused by shaking during transportation.

[0028] 3. During installation, rotate the fixing plates to a parallel installation state, slide the protective plates close to the fixing plates, and lock the fixing plates in the installed state with the help of locking parts to ensure the stability of the fixing plates during installation, so as to facilitate the subsequent use of flexible fixing ropes and arc-shaped notches to surround the poles for pre-locking.
