Description

Technical Field

[0001] This utility model relates to the field of meter box technology, specifically to an indoor meter box structure. Background Technology

[0002] A meter box is a device used to store electricity meters. According to electrical wiring requirements, switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment are assembled inside the meter box, and the market often has requirements for the protection level of the meter box.

[0003] An electrical meter box typically consists of a bottom and a cover. The bottom has a forward-opening cavity; the cover is rotatably mounted on the bottom and is used to open or close the opening of the cavity. For example, wiring and maintenance require opening the cover. Commonly, for protection, the cover is rigidly fixed on all four sides with high-strength bolts (mostly hexagonal bolts). Although the meter box itself is opened infrequently, the bolts require the corresponding tools, which is inconvenient. For indoor meter boxes, where anti-theft measures are not required, ensuring protection and convenience is sufficient. Therefore, the screw structure, which is inconvenient to disassemble and easily lost, can be further improved. Utility Model Content

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0019] like Figure 1-5The diagram shows an indoor meter box structure, including a box body 1 and a box cover 2. The box body 1 and the box cover 2 form a mounting cavity 3 for electrical components 9. Fasteners 4 are provided around the box body 1. The fasteners 4 are hinged to lock the box cover 2 to close it to the box body 1. The box cover 2 includes a cover body 21 and a base plate 22. The base plate 22 is matched and inserted into a notch 12 provided at the bottom of the box body 1. The base plate 22 and the box body 1 also cooperate to form a plurality of cable holes 23.

[0020] As a further provision of the above solution, the fastener 4 includes a hook plate 41, a rotating rod 42, a reverse pressure plate 43, and a hinge shaft 44. The reverse pressure plate 43 is connected to the housing 1 through the hinge shaft 44, and the hook plate 41 is connected to the reverse pressure plate 43 through the rotating rod 42.

[0021] As a further feature of the above solution, the cover 21 and the base plate 22 are connected by a hinge 25, and the cover 21 has fastening grooves 26 on all four sides corresponding to the fasteners 4.

[0022] As a further provision of the above scheme, the inner side of the base plate 22 is also provided with a spring lock pin 5, and the box body 1 is provided with a buckle opposite to the spring lock pin 5. The spring lock pin 5 includes a pin seat 52, a pin rod 53 and an elastic element 54.

[0023] As a further provision of the above solution, the cover 2 is also provided with an observation window 28 and an operation window 29. The observation window 28 and the operation window 29 are positioned facing the internal electrical components 9, and the operation window 28 is provided with an operation push plate 24.

[0024] As a further feature of the above solution, a concave locking part 13 is provided at the notch 12, and the width of the concave locking part 13 is matched and inserted into the base plate 22.

[0025] refer to Figure 1 The meter box of this utility model shown includes a conventionally configured box body 1 and box cover 2 structure. The box cover 2 is provided with an observation window 28 of a transparent acrylic plate 27 for observing and reading the values ​​of electrical components 9. The box cover 2 is also provided with an operation window 29 for operating the internal protective electrical appliances (generally circuit breakers). The operation window 29 is closed by an operation push plate 24. After being pushed open, a finger can be inserted to operate the circuit breaker.

[0026] Further, such as Figure 2As shown, the housing 1 of this embodiment has an installation cavity 3 for the installation of electrical components 9. Unlike existing technologies where the housing 1 and cover 2 are typically fixed with bolts, this embodiment uses a fastener 4 locking mechanism. The fastener 4 allows the user to release the lock between the cover 2 and housing 1 without tools by simply unfastening the fasteners 4 on all four sides of the meter box. The cover 2 can then be flipped down to open the installation cavity 3. Furthermore, the cover 2 of this embodiment also features... Figure 3 The base plate 22 shown is connected to the cover 21 of the box cover 2 via a hinge 25. Furthermore, the cable hole 23 for the electric meter box is formed by the base plate 22 and the box body 1. Both are provided with half of their interlocking openings to form a complete circle to clamp the cable and the rubber sealing sleeve. The separation structure between the base plate 22 and the box body 1 is formed by the cooperation of the spring lock pin 5 and the concave locking part 13. The concave locking part 13 allows the base plate 22 to be disengaged and installed only along the slot direction of the notch 12, while the spring lock pin 5 locks the disengagement direction.

[0027] Furthermore, as described above, the fastener 4 in this embodiment includes a hooked buckle plate 41 and a reverse pressure plate 43 that are hinged to each other via a rotating rod 42. The reverse pressure plate 43 is connected to the box body 1 via a hinge shaft 44. When the box cover 2 and the box body 1 are connected, the box cover 2 is simply fastened to the front of the box body 1. Then, the hooked buckle plate 41 is fastened to the buckle groove 26, and then the reverse pressure plate 43 is pressed against the box body 1 to fit together. The two form a certain locking force, so that the fastener 4 continuously locks the box body 1 and the box cover 2.

[0028] In this embodiment, the cover 2 is designed for installation and removal based on the base plate 22. During routine maintenance and operation / installation of the internal electrical components 9, the cover 2 can... Figure 2 The structure is used so that the cover 21 remains hinged to the base plate 22. The spring lock pin 5 of the base plate 22 does not need to be unlocked. When it is necessary to operate the wire, the pins 53 on both sides of the base plate 22 can be pulled further to move them towards the center, compress the elastic element 54, and make the front end of the pin 53 disengage from the buckle on the inner wall of the box 1, thereby releasing the lock with the box 1. Then the base plate 22 can be operated to disengage from the concave card part 13, disengage from the notch 12 and separate from the box 1 for disassembly.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
