Technical Field

[0001] This utility model belongs to the technical field of power meter boxes, specifically a meter box that is easy to maintain. Background Technology

[0002] A search revealed Chinese patent application number 202222373412.2, which discloses a meter box. Addressing the issue that existing meter readings require transcription, the lack of external light during transcription leads to illegible numbers, errors, and disruptions to subsequent work. Furthermore, the meter, being an electrical component, is susceptible to moisture and dust, which can damage internal electronic components and cause malfunctions. The proposed solution includes a box housing and multiple meter books. The box housing incorporates dehumidification and lighting mechanisms, as well as ventilation components, ensuring the internal air remains dry and clean, preventing overheating, and guaranteeing normal operation of the meter books. The meter books are clearly legible even without external light, ensuring accuracy during transcription. The semi-enclosed structure of the box prevents insects and other foreign objects from entering, safeguarding the meter books.

[0003] Although the aforementioned patent incorporates dehumidification and lighting mechanisms, as well as ventilation components on the casing to keep the air inside the casing dry and clean, prevent excessively high temperatures, ensure the normal operation of the meter book, and allow for clear reading of the meter book values ​​even without external light sources during transcription, thus guaranteeing the accuracy of the transcribed values, and features a semi-enclosed internal structure to prevent insects and other foreign objects from entering the casing and ensuring the safety of the meter book, in actual use, the existing casing has a relatively small internal space. Meters are prone to malfunction after prolonged use, requiring timely repairs. Furthermore, tools are not easily inserted into the casing to disassemble the meters, making repairs inconvenient for maintenance personnel.

[0004] Therefore, it needs to be modified so that when the meter needs to be inspected or repaired, it can be pushed out of the housing and exposed to the outside of the housing, making it easier to inspect, repair or replace the meter. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a meter box that is convenient for maintenance. When a meter needs maintenance, it can be pushed out of the box, exposing the entire meter to the outside, facilitating inspection, repair, and replacement. This improves user convenience and solves the problems of existing boxes having limited internal space, meters being prone to malfunction after prolonged use, requiring timely maintenance, and tools being difficult to extend into the box to disassemble the meter, leading to inconvenience for maintenance personnel.

[0006] This utility model provides the following technical solution: a meter box for easy maintenance, comprising a box body, an upper mounting plate disposed inside the box body, a plurality of meter books disposed on the front of the mounting plate, first support rods hinged to the upper left and right sides of the back of the mounting plate, and second support rods hinged to the lower left and right sides of the back of the mounting plate, the rear ends of the first and second support rods being hinged to the rear side of the inner wall of the box body, and a round rod slidably connected to one side of the two first support rods, with a ring sleeve rotatably connected to the left and right sides of the surface of the round rod, a support plate fixedly connected to the lower rear side of the inner wall of the box body, and a multi-stage electric telescopic rod fixedly connected to the left and right sides of the top of the support plate, the output end of the multi-stage electric telescopic rod being fixedly connected to the bottom of the ring sleeve, and a winding roller corresponding to each meter book being rotatably connected to the upper and lower sides of the left and right sides of the inner wall of the box body, the surface of the winding roller being provided with an insulating coating.

[0007] The beneficial effects of this utility model are as follows:

[0008] 1. This utility model mounts the meter on the front of a mounting plate, which is then positioned inside the housing via a first and second support rod. When the meter needs maintenance, a multi-stage electric telescopic rod retracts, causing a ring to move downwards. This movement, in turn, moves a round rod downwards, which slides downwards along the inner sides of the two first support rods. This causes the front ends of the first support rods to move forward and downwards, moving the mounting plate forward and downwards. Simultaneously, the second support rod moves along with the rod, supporting the mounting plate and pushing both the meter and the mounting plate out of the housing. Furthermore, a winding roller is included to wind excess wire around the meter when it is connected to the wire. When the meter is removed from the housing, the wire on the winding roller is stretched, preventing the wire from breaking during movement and affecting its use. This design allows the meter to be easily removed from the housing for maintenance, exposing it completely for inspection, repair, and replacement.

[0009] 2. This utility model, through the corresponding arrangement of the locking rod, pull ring, tension spring, and baffle, provides support and limits the mounting plate when it does not need to be moved, keeping the mounting plate vertical inside the housing and preventing it from tilting due to the weight of the meter. When the meter needs to be repaired, the pull ring can be pulled to the right, causing the locking rod to move to the right and releasing the limitation on the mounting plate.

[0026] In this embodiment, by setting the corresponding slider 25 and the slide groove 26, the round rod 6 is limited and reinforced, so that it will not fall off from the inside of the two first support rods 4 when it moves up and down. At the same time, it makes the movement smoother and avoids the round rod 6 from falling off and getting stuck when it moves up and down, which would affect normal use.

[0027] This invention mounts the meter 3 on the front of the mounting plate 2, and the mounting plate 2 is placed inside the housing 1 by the first support rod 4 and the second support rod 5. When the meter 3 needs to be inspected, the multi-stage electric telescopic rod 9 can be activated to retract it. The retraction of the multi-stage electric telescopic rod 9 drives the ring 7 to move downward, which in turn drives the round rod 6 to move downward. When the round rod 6 moves downward, it slides downward inside the two first support rods 4, causing the front end of the first support rod 4 to move forward and downward. When the front end of the first support rod 4 moves forward and downward, it drives the mounting plate 2 to... The meter moves forward and downward, and the second support rod 5 moves accordingly to support the mounting plate 2, pushing the mounting plate 2 and the meter 3 out of the housing 1. At the same time, by setting the winding roller 10, excess wire can be wound around the winding roller 10 when the meter 3 is connected to the wire. When the meter 3 is moved out of the housing 1, the wire on the winding roller 10 is stretched to prevent the wire from being broken when the meter 3 moves, which would affect its use. In this way, when the meter 3 needs to be inspected and repaired, it can be pushed out of the housing 1, so that it is completely exposed outside the housing 1, making it convenient for the meter 3 to be inspected, repaired and replaced.
