Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric meter box, especially relates to a space-saving electric meter box. BACKGROUND

[0002] With the popularization and development of electric power facilities, the electric meter box as an important carrier of electric energy metering equipment is widely used in residential buildings, commercial buildings and industrial sites. The traditional electric meter box is usually composed of a main box body, a fixed door plate and an internal mounting bracket, and its design is mainly to meet the basic protection and installation requirements. However, in actual application, especially in space-limited installation scenes (such as narrow corridors, dense power distribution areas, etc.), the structure of the traditional electric meter box gradually exposes problems such as low space utilization rate and inconvenient maintenance. The door plate of the existing electric meter box is usually designed as an outward opening type or a sliding type. The outward opening door plate needs to occupy the external space of the box body, which is easily hindered by walls or other equipment in a narrow environment, leading to difficulty in opening. While the sliding door plate can reduce the occupation of external space, but its sliding rail structure usually extends along the side or top of the box body, resulting in the internal space of the box body being occupied by the sliding rail assembly, affecting the layout density of the electric meter and electrical elements. In addition, the opening and closing mechanism of the traditional door plate usually uses a single hinge or fixed sliding rail, which lacks flexible adjustment capability, and it is difficult to quickly position or completely avoid the operation area during maintenance or repair, increasing the operation complexity.

[0003] On the other hand, the internal structure of the existing electric meter box is usually designed with fixed partitions, and the functional partition is single, which is difficult to adapt to the installation requirements of electric meters and auxiliary equipment of different specifications. Especially in the scene where multiple meters are installed together, the traditional box body is often forced to increase the overall size due to unreasonable space allocation, further aggravating the space occupation contradiction. Some improved schemes try to optimize the layout by adding detachable partitions, but the disassembly and assembly process is complicated, and the problem of coordinated optimization of door plate opening and closing and internal space is not solved. Therefore, the existing technology needs to be improved and improved. SUMMARY

[0034] This utility model provides a space-saving meter box. To make the purpose, technical solution and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments.

[0035] In the description of this utility model, it should be understood that the terms "up, down, left, right" and other indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation" and "connection" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Please see Figures 1 to 6 This utility model provides a space-saving meter box, including a main body 1, a left side panel 2, a partition 3, a receiving space 4, a movable door panel 5, a hinge 6, a composite bracket 7, and a slide rail assembly 8. The main body 1 is integrally formed from aluminum alloy material with a wall thickness of 1.2mm-2.5mm. The surface is anodized to form an anti-corrosion layer to adapt to outdoor humid or acidic / alkaline environments. The left side panel 2 is vertically arranged on the left side of the main body 1, and the partition 3 is vertically inserted into the inner cavity of the main body 1 through a dovetail groove. The partition 3 divides the internal space of the main body 1 into two areas, and the layout can be flexibly adjusted according to the number and size of the meters. One of the areas is the receiving space 4. It is fixed by the dovetail groove without bolts or welding, which facilitates quick installation and disassembly. A narrow receiving space 4 is formed between the partition 3 and the left side panel 2, and the slide rail assembly 8 is disposed in the receiving space 4. The slide rail assembly 8 includes an inclined section 81 and a horizontal section 82. The inclined section 81 is located near the front of the main housing 1, with an inclination angle of 10°-45°. The end of the inclined section 81 is connected to the horizontal section 82. The horizontal section 82 extends horizontally along the depth direction of the main housing 1 to the end of the receiving space 4. The inclined section 81 and the horizontal section 82 are connected by an arc-shaped transition section with a radius of curvature of 5mm-10mm to eliminate stress concentration problems at traditional right-angle turns and reduce the sliding resistance of the slider.

[0037] The movable door panel 5 includes a metal substrate, an acrylic panel 51, and a handle 52. The inner side of the metal substrate is fixedly connected to the composite bracket 7 via a hinge 6. The acrylic panel 51 is detachably installed on the outer side of the metal substrate for easy replacement or cleaning of the observation window. The handle 52 is fixedly installed on the outer side of the metal substrate for convenient user operation.

[0038] The composite bracket 7 consists of a fixed plate 71 and a slider 72. One side of the fixed plate 71 is riveted to the hinge 6, and the other side is equipped with the slider 72. The slider 72 is slidably disposed within the slide rail assembly 8, realizing the sliding function of the movable door panel 5. The riveting connection method simplifies the assembly process while ensuring connection strength and vibration resistance.

[0039] The inclined section 81 of the slide rail assembly 8 integrates an anti-disengagement locking device. This device includes a spring buckle and a slot. The spring buckle is mounted on the slider 72, and the slot is mounted on the inner wall of the slide groove of the slide rail assembly 8. When the movable door panel 5 is closed, the spring buckle engages with the slot, automatically locking the slider 72 to prevent the door panel from opening accidentally due to vibration or accidental contact, thus enhancing safety. To unlock, the user only needs to press the spring buckle to easily open the movable door panel 5 without additional tools. The movable door panel 5 is installed on the left side of the main housing 1 via the composite bracket 7 and the slide rail assembly 8. The sliding opening and closing of the movable door panel 5 is achieved through the inclined section 81 and the horizontal section 82 of the slide rail assembly 8.

[0040] The anti-derailment locking device automatically locks when the door is closed, ensuring the safety of the meter box. If any component in the slide rail assembly 8 or the composite bracket 7 is damaged, the user can replace the damaged component individually. For example, to replace the slider 72, simply remove the rivets, take off the fixing plate 71, replace the new slider 72, and reassemble. The removable design of the acrylic panel 51 also facilitates cleaning or replacement of the observation window, further improving the maintenance convenience of the meter box.

[0041] When the user needs to accommodate the movable door panel 5, the movable door panel opens along the hinge, pushing the composite bracket 7, which, along with the slider 72, slides upward along the inclined section 81, then enters the horizontal section 82 and moves horizontally until the door panel enters the accommodating space 4. To use the movable door panel, simply reverse the operation. Throughout the entire process, the movable door panel 5 will not fold outwards and occupy external space.

[0042] In summary, this space-saving meter box utilizes a hinged hinged structure connecting the movable door panel to a composite bracket. The composite bracket slides along a sliding rail assembly within the elongated, narrow storage space inside the main box, allowing the movable door panel to be completely retracted into the storage space formed by the left side panel and the partition when open. Compared to traditional outward-opening or sliding door panels, this design eliminates the need for additional external space for the door panel to open or slide, and avoids the problems of external sliding rails occupying the core installation area of ​​the main box. When the door panel is open, its overall movement trajectory is confined within the main box. Guided by the sliding rails and the compact layout of the storage space, the movement path of the movable door panel is minimized, significantly reducing the space requirements for the installation environment during opening and closing. Furthermore, the integrated design of the storage space and the sliding rail assembly not only ensures the stability of the door panel during storage but also allows the remaining area inside the main box to be efficiently used for the arrangement of meters and electrical components, further improving space utilization. This structure is particularly suitable for narrow or densely packed installation scenarios, effectively solving the space conflict problem caused by the opening and closing of traditional meter boxes while ensuring convenient operation and maintenance. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0043] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
