Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and more specifically to an electric meter box that is easy to maintain. Background Technology

[0002] To facilitate maintenance, existing meter boxes typically employ a combination structure of a box body and a door, with the door hinged to the box body for easy access and inspection. However, this traditional structure has significant drawbacks in practical use: the door often flips and closes on its own during maintenance, hindering user operations and potentially impacting equipment maintenance efficiency and safety. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric meter box that is convenient for maintenance. By using a universal rotating connection structure between the box door and the box body, the problem of the box door automatically flipping and closing during maintenance is solved.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a meter box that is easy to maintain, including a box body and a box door, wherein a shaft is rotatably threaded through the side of the box door, and the lower end of the shaft is connected to the box body through a universal ball joint.

[0005] As a further improvement of this utility model, a rotating groove is provided on the housing at the position relative to the upper end of the shaft, and a telescopic head is provided at the upper end of the shaft. The telescopic head can extend and be inserted into the rotating groove, or retract and be removed from the rotating groove.

[0006] As a further improvement of this utility model, the lower side of the box body protrudes outward to form a support edge, so as to support the box door after the box door is flipped downward.

[0007] As a further improvement of this utility model, the shaft includes a lower rod, and a cylindrical shaft groove is provided on the side of the door. The telescopic head and the lower rod are both inserted into the shaft groove. A universal ball joint is installed at the lower end of the lower rod. A spring is provided between the lower end of the telescopic head and the upper end of the lower rod. A push block is fixed on the side of the telescopic head. The push block extends out of the shaft groove for manual pushing, driving the telescopic head to insert into the rotating groove, or retract and disengage from the rotating groove.

[0008] As a further improvement of this utility model, several magnets are embedded in the inner wall of the box, and the side of the box door is made of magnetic material.

[0009] As a further improvement of this utility model, a magnetic column is coaxially embedded at the upper end of the shaft, and the inner sidewall of the box is made of magnetic material.

[0010] The beneficial effects of this invention are that the universal ball joint enables multi-angle rotation of the cabinet door, solving the problem of the door easily closing itself due to traditional hinge connections. During maintenance, the universal ball joint allows the cabinet door to flip downwards and lie flat, avoiding obstruction caused by rotation and using the flat door as a storage platform, thus improving the safety and efficiency of maintenance operations. The cooperation between the telescopic head and the rotating groove secures the cabinet door, the support edge enhances the stability of the flipping mechanism, and the magnet and magnetic column structure further optimizes the ease of opening and closing. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 for Figure 1 Schematic diagram of the middle box door; Figure 3 for Figure 2 Enlarged view of section A in the middle; Figure 4 This is a structural schematic diagram of another embodiment of the shaft. Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0013] Reference Figures 1 to 4 As shown, the meter box for convenient maintenance in this embodiment includes a box body 1 and a door 2. A shaft 3 is rotatably threaded through the side of the door 2, and the lower end of the shaft 3 is connected to the box body 1 via a universal joint 4. During maintenance, the door 2 can be flipped down to a horizontal position due to the multi-angle rotation characteristics of the universal joint 4, avoiding the unidirectional rotation limitation of traditional hinge structures. This effectively prevents the door 2 from closing automatically due to gravity during maintenance, solving the problem of operational obstruction in the prior art. The horizontally placed door 2 can also be used as a storage platform.

[0014] Furthermore, refer to Figure 1 As shown, a rotating groove is provided on the housing 1 at a position relative to the upper end of the shaft 3. The upper end of the shaft 3 is provided with a telescopic head 31, which can extend and insert into the rotating groove or retract and exit from the rotating groove 11. The extension and retraction of the telescopic head 31 is controlled by the push block 33, so that when maintenance is not required, the fit between the door 2 and the housing 1 is the same as that of the hinge in the prior art, which is convenient for the user to observe.

[0015] Furthermore, a support edge 12 protrudes outward from the lower side of the housing 1 to support the housing door 2 after it is flipped downward. The support edge 12 cooperates with the universal ball joint 4 to form a stable horizontal support structure, preventing the housing door 2 from shaking after it is flipped and enhancing the stability of the maintenance platform.

[0016] Furthermore, the shaft 3 includes a lower rod 32, and a cylindrical shaft groove 21 is provided on the side of the door 2. The telescopic head 31 and the lower rod 32 are both inserted into the shaft groove 21. A universal ball joint 4 is installed at the lower end of the lower rod 32. A spring is provided between the lower end of the telescopic head 31 and the upper end of the lower rod 32. A push block 33 is fixed to the side of the telescopic head 31. The push block 33 extends out of the shaft groove 21 for manual pushing, driving the telescopic head 31 to insert into the rotating groove or retract and disengage from the rotating groove 11. The spring provides automatic return force, simplifying the operation steps, and the external design of the push block 33 improves the ease of operation.

[0017] Furthermore, several magnets are embedded in the inner wall of the enclosure 1, and the sides of the enclosure door 2 are made of magnetic material. The magnetic structure helps the enclosure door 2 to fit tightly when closed, enhancing its dustproof and waterproof performance.

[0018] Furthermore, this embodiment provides another implementation of the shaft 3. A magnetic column 34 is coaxially embedded at the upper end of the shaft 3, and the inner wall of the housing 1 is made of magnetic material. Since the existing universal joint 4 itself has a certain damping, the opening and closing of the door 2 can be stopped at any time. When observation is needed but maintenance is not required, the universal joint 4 is flipped so that the shaft 3 is vertical, so that the connection between the shaft 3 and the door 2 is the existing hinge connection. In this process, the magnetic column 34 can further strengthen the vertical state of the shaft 3, avoiding the problem of the shaft 3 flipping when the door 2 is opened for observation, which would cause the door 2 to flip.

[0019] In summary, this utility model achieves multi-angle rotation and stable support of the meter box door through the combination structure of the universal ball joint 4 and the shaft 3, enabling the box door 2 to have multiple opening states, and is adapted to both observation and maintenance use.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
