Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor controller. Background Art

[0002] A controller is a main command device that changes the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order to control the starting, speed regulation, braking and reversal of the motor. As the use of motors continues to increase, the manufacture of motor controllers is also increasing to ensure the controllability of the motor when it is used.

[0003] However, the motor controllers currently on the market are mostly integrated designs, which are difficult to quickly disassemble after a failure occurs, making it inconvenient for subsequent maintenance work; furthermore, the display screen is difficult to be well protected when not in use. For this reason, we propose a motor controller. Utility Model Content

[0007] Furthermore, a T-shaped slide groove is provided on the shell, a T-shaped slider is slidably connected to the inner side of the T-shaped slide groove, and the T-shaped slider is connected to the plug block.

[0008] Furthermore, the insert block is also connected to a movable plate, the movable plate is connected to a sliding column, the shell is also rotatably connected to a rotating plate, the rotating plate is provided with a slot, and the sliding column is slidably connected to the inner side of the slot.

[0009] Furthermore, a connecting shaft is connected to the rotating plate, one end of the connecting shaft is rotatably connected to the shell, the other end of the connecting shaft is connected to a worm wheel, and a worm is also rotatably connected to the shell, and the worm is meshed with the worm wheel.

[0010] Furthermore, the housing is also connected to a connecting plate, the worm is rotatably connected to the connecting plate, and the connecting plate is also rotatably connected to a hand wheel, the hand wheel passes through the connecting plate near one end of the connecting plate and is connected to the end of the worm.

[0011] Furthermore, the front cover is connected to a fixed plate, the limit rod is slidably connected to the fixed plate, the limit rod is connected to a movable sheet, the limit rod is also sleeved with a spring, one end of the spring is connected to the movable sheet, and the other end of the spring is connected to the fixed plate.

[0012] Furthermore, a pull ring is connected to one end of the limiting rod away from the limiting groove.

[0013] The beneficial effects of the utility model are as follows:

[0014] The utility model enables the plug block to slide on the top of the shell, thereby connecting or separating the plug block from the inner side of the slot, thereby limiting or releasing the limit of the second fixing block, thereby facilitating the closing or opening of the front cover. When a fault occurs inside the shell, the front cover is opened to inspect the inside of the shell, thereby solving the problem that the motor controllers currently on the market are mostly of integrated design, which are difficult to disassemble quickly after a fault occurs, making it inconvenient for later maintenance work.

[0015] The protective cover of the utility model rotates on the front side of the front cover, and then the protective cover is covered on the front side of the front cover. Under the action of the empty groove, the display screen can be stored in the empty groove, and then the display screen is protected, so as to avoid that the display screen is exposed to the outside when the device is not in use, and the display screen is easily touched and damaged. The limit rod slides on the front cover, so that the limit rod is separated from or clamped with the limit groove. When the limit rod is separated from the limit groove, it contacts the limit of the first fixed block, and then the protective cover is opened. When the limit rod is clamped with the inner side of the limit groove, the first fixed block is limited, and then the protective cover is closed, thereby solving the problem that the display screen is difficult to obtain a good protection when not in use.

The protective cover 3 rotates on the front side of the front cover 2, and then the protective cover 3 is covered on the front side of the front cover 2. Under the action of the empty slot 7, the display screen 4 can be stored in the empty slot 7, and then the display screen 4 is protected to prevent the display screen 4 from being exposed to the outside when the device is not in use, and it is easy to touch the display screen 4 and damage it. The limit rod 24 slides on the front cover 2, and then the limit rod 24 is separated or clamped from the limit slot 6. When the limit rod 24 is separated from the limit slot 6, it contacts the limit of the first fixed block 5, and then the protective cover 3 is opened. When the limit rod 24 is clamped with the inner side of the limit slot 6, the first fixed block 5 is limited, and then the protective cover 3 is closed, thereby solving the problem that the display screen is difficult to get a good protection when not in use.

[0024] like Figure 4 As shown, in some embodiments, a T-shaped groove 12 is further provided on the shell 1, and a T-shaped slider 11 is slidably connected to the inner side of the T-shaped groove 12. The T-shaped slider 11 is connected to the plug block 10, and the T-shaped slider 11 slides on the inner side of the T-shaped groove 12, thereby making the plug block 10 slide on the shell 1, and the T-shaped slider 11 and the T-shaped groove 12 have a limiting function, so that the plug block 10 slides linearly on the shell 1.

[0025] like Figure 4As shown, in some embodiments, a movable plate 13 is also connected to the plug 10, and a sliding column 21 is connected to the movable plate 13. The shell 1 is also rotatably connected to a rotating plate 14, and a slot 20 is provided on the rotating plate 14. The sliding column 21 is slidably connected to the inner side of the slot 20. The rotating plate 14 rotates on the shell 1, so that the sliding column 21 slides on the inner side of the slot 20, thereby driving the movable plate 13 to slide left and right, and then driving the plug 10 to slide left and right.

A hand wheel 17 is also rotatably connected to the connecting plate 18. The hand wheel 17 passes through the connecting plate 18 at one end close to the connecting plate 18 and is connected to the end of the worm 19. By rotating the hand wheel 17, the worm 19 can be driven to rotate.

[0028] like Figure 2 , Figure 3 , Figure 5 As shown, in some embodiments, a fixed plate 26 is connected to the front cover 2, and the limit rod 24 is slidably connected to the fixed plate 26. A movable sheet 22 is connected to the limit rod 24. A spring 23 is also sleeved on the limit rod 24, and one end of the spring 23 is connected to the movable sheet 22, and the other end of the spring 23 is connected to the fixed plate 26. By pulling the limit rod 24, the limit rod 24 is separated from the limit slot 6, and the movable sheet 22 is driven to move, and the spring 23 is squeezed to relax the limit rod 24. Under the action of the spring 23, the movable sheet 22 is driven to move in the opposite direction, so that the limit rod 24 is re-engaged with the inner side of the limit slot 6.

[0029] like Figure 5 As shown, in some embodiments, a pull ring 25 is connected to one end of the limiting rod 24 away from the limiting groove 6, and the limiting rod 24 can be driven to move by pulling the pull ring 25.
