[0002] Electrical work is an indispensable profession in the chemical industry, bearing the important mission of maintaining the normal operation of the entire factory. When maintaining and repairing circuits, electricians commonly use three main categories of tools: general-purpose tools, wiring installation tools, and equipment installation tools. Traditional electrical maintenance boxes consist of an upper and lower box hinged together. However, on uneven ground or in sloping work areas, maintenance boxes without angle adjustment supports are prone to tipping over. Once the maintenance box tipps over, it may not only damage the precision instruments and tools inside, but also potentially injure maintenance personnel. Therefore, we propose a convenient electrical box for installation and maintenance. Utility Model Content

[0020] Please see Figures 1-5 As shown, this embodiment provides a conveniently installed and maintained power box, including a lower box 1, an upper box 2 hinged to the upper side of the lower box 1, and a support device 3 provided on the outer side of the lower box 1 and the upper box 2. The support device 3 is used to support and fix the upper box 2. The support device 3 includes a first connecting rod 31 and a second connecting rod 32 slidably disposed inside the first connecting rod 31. A connecting rod groove 4 is opened on the upper surface of the upper box 2. The first connecting rod 31 is hinged inside the connecting rod groove 4. One end of the second connecting rod 32 is fixedly connected to a first spring 33 located inside the first connecting rod 31. The lower box... The lower surface of the device has a slot 5 for the card plate, and a card plate 36 is slidably disposed inside the slot 5. The upper surface of the card plate 36 has multiple slots 37. The end of the second connecting rod 32 is movably engaged inside the slot 37. When the user pulls out the card plate 36 and rotates the first connecting rod 31, the elastic thrust applied by the first spring 33 to the second connecting rod 32 pushes out and fixes the second connecting rod 32. The user can rotate the upper box 2 as needed and insert the second connecting rod 32 into the corresponding slot 37, so that the first connecting rod 31 and the second connecting rod 32 support and fix the upper box 2, making it convenient to use.

[0021] A guide groove 6 is provided on one side of the card slot 5. A guide rod 38 is slidably disposed inside the guide groove 6. The guide rod 38 is fixedly installed on one side of the card 36. The sliding of the guide rod 38 inside the guide groove 6 guides the card 36. At the same time, a second limiting groove 39 is provided on the other side of the card 36. A second limiting block 391 is slidably disposed inside the second limiting groove 39. The second limiting block 391 is fixedly installed inside the card slot 5. The sliding of the second limiting block 391 inside the second limiting groove 39 limits the card 36, preventing the first connecting rod 31 from being aligned with the upper part of the card. When the box body 2 is supported, the horizontal thrust exerted by the second connecting rod 32 on the card plate 36 is too large, causing the card plate 36 to slip out of the card plate groove 5. At the same time, a first limiting groove 34 is provided on the outer side of the second connecting rod 32, and a first limiting block 35 is slidably disposed inside the first limiting groove 34. The first limiting block 35 is fixedly installed inside the first connecting rod 31. The sliding of the first limiting block 35 inside the first limiting groove 34 guides and limits the sliding of the second connecting rod 32, preventing the second connecting rod 32 from slipping out and failing to effectively support the upper box body 2.

[0022] A groove is provided on the other side of the card slot 5. An insert 7 is slidably disposed inside the groove. A second spring 8 located inside the groove is fixedly connected to the side of the insert 7 away from the card slot 5. When the device is idle, the elastic thrust applied to the insert 7 by the second spring 8 pushes the insert 7 out and makes one end of the insert 7 stuck inside the second limiting groove 39, thereby fixing the card 36 and preventing the card 36 from sliding sideways. At the same time, a positioning groove is provided on the upper side of the groove. A positioning block is slidably disposed inside the positioning groove. The positioning block is fixedly installed on the insert 7. The sliding of the positioning block inside the positioning groove limits the insertion 7, preventing the insert 7 from slipping out and thus failing to effectively fix the card 36. A protruding rod 9 is fixedly connected to the lower side of the insert 7. The protruding rod 9 passes through the lower side of the lower box 1 and extends outward.

[0023] In this embodiment of the convenient installation and maintenance power box, when in use, the user first pulls the protruding rod 9 to move the plug 7 away from the card plate 36 and pulls out the card plate 36. Then, the user rotates the first connecting rod 31, and the elastic thrust applied by the first spring 33 to the second connecting rod 32 pushes out the second connecting rod 32. The user holds the first connecting rod 31 to rotate the upper box 2. When the upper box 2 is adjusted to an appropriate angle, the end of the second connecting rod 32 is locked in the corresponding slot 37, so that the first connecting rod 31 supports and fixes the upper box 2.
