The observation port 34 is provided to perform an observation function, which is convenient for the staff to observe the low-voltage electrical main body 3. A second rotating shaft 15 is provided on the left and right sides of 1 and at the position behind the first rotating shaft 11. The surface of the second rotating shaft 15 is movably connected with a driven wheel 16, and the driving wheel 14 is drivingly connected to the driven wheel 16 through a transmission chain 17. The left and right sides of the bottom of the top plate 7 are fixedly connected with connecting blocks 18 corresponding to the position of the transmission chain 17. The connecting block 18 is fixedly connected with the transmission chain 17 through the connecting rod 19, and the end of the first rotating shaft 11 away from the driving wheel 14 is fixedly connected with the turntable 20, A handle 21 is fixedly connected to the side of the turntable 20 away from the first rotating shaft 11. The handle 21 makes the first rotating shaft 11 rotate with the rolling bearing 13 inside the limiting groove 12, and the first rotating shaft 11 The driving wheel 14 rotates, the driving wheel 14 drives the driven wheel 16 to rotate through the transmission chain 17, and the transmission chain 17 moves the top plate 7 backward through the connecting block 18 and the connecting rod 19, and the top plate 7 drives the first slider 6 on the first slide rail. The inner sliding of 5 drives the second sliding block 9 to slide inside the second slide rail 8. The top of the handle 21 is fixedly connected to the limit rope 22, the top end of the limit rope 22 is fixedly connected to the limit block 23, and the left and right sides of the top plate 7 The two sides are fixedly connected with a clamping block 24, and the left and right sides of the clamping block 24 are provided with clamping grooves 25 adapted to the position of the limiting block 23. The first sliding rail 5 and the first sliding block 6 are provided. , Top plate 7, second sliding rail 8, second sliding block 9, sliding rod 10, first rotating shaft 11, limiting groove 12, rolling bearing 13, driving wheel 14, second rotating shaft 15, driven wheel 16, transmission chain 17, The connecting block 18, the connecting rod 19, the turntable 20, the handle 21, the limit rope 22, the limit block 23, the clamping block 24 and the clamping groove 25 cooperate with each other. The slide rail and the sliding block are assembled to facilitate maintenance personnel. Maintenance of low-voltage electrical appliances can repair damaged low-voltage electrical appliances in a timely manner, which improves maintenance efficiency, not only saves time and effort, but also reduces the labor intensity of maintenance personnel and brings great convenience to maintenance personnel.

[0020] When in use, the clamping block 24 is taken out of the clamping groove 25 through the limit rope 22, and then the first rotating shaft 11 rotates with the rolling bearing 13 inside the limit groove 12 through the handle 21, and the first rotating shaft 11 drives the drive The wheel 14 rotates, the driving wheel 14 drives the driven wheel 16 to rotate through the transmission chain 17, the transmission chain 17 makes the top plate 7 move backward through the connecting block 18 and the connecting rod 19, and the top plate 7 drives the first slider 6 on the first slide rail 5. Internal sliding drives the second sliding block 9 to slide inside the second sliding rail 8 to open the housing 1 so that maintenance personnel can maintain the main body 3 of the low-voltage electrical appliance.

[0021] To sum up: the low-voltage electrical appliance that is easy to maintain is provided with a first slide rail 5, a first slide block 6, a top plate 7, a second slide rail 8, a second slide block 9, a slide rod 10, a first rotating shaft 11, Limit groove 12, rolling bearing 13, driving wheel 14, second rotating shaft 15, driven wheel 16, transmission chain 17, connecting block 18, connecting rod 19, turntable 20, handle 21, limit rope 22, limit block 23, card The connecting block 24 and the clamping groove 25 cooperate with each other to solve the problem of inconvenient maintenance of common low-voltage electrical appliances.
