[0002] In the field of modern industrial automation, stepping motors are widely used due to their precise position control and easy operation. However, with the increasingly complex and diverse usage scenarios of stepping motor drivers, the leakage problem has gradually become a safety hazard that cannot be ignored.

[0003] The patent document with the publication number CN207603490U discloses a stepping motor driver with a leakage warning function, including a temperature and humidity display, a stepping motor driver body, a driver base, and a leakage protector. The temperature and humidity display is installed on the top of the stepping motor driver body through a connecting seat. One side of the stepping motor driver body is provided with a connecting area, and an interface end is provided on one side within the connecting area. An indicator signal lamp is provided on one side of the interface end. A leakage protector is provided at the bottom of the interface end, and a small electrostatic eliminator is installed on one side of the leakage protector through a mounting bracket. A heat sink is provided at the bottom of the connecting area, and an air outlet is provided on one side of the heat sink. One end of the stepping motor driver body is installed with an alarm through a mounting seat.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] In this embodiment, four groups of supporting legs 16 are fixedly installed on the bottom of the frame 13, and a bottom plate 14 is slidably installed on the bottom of the frame 13. The outer sides of the four groups of supporting legs 16 are slidably installed in the bottom plate 14. A turntable 20 is rotatably installed on one side of the frame 13, and a bidirectional screw rod 19 is fixedly installed on one side of the turntable 20. The outer side of the bidirectional screw rod 19 is threadedly connected with two groups of moving seats 25. The bottoms of the two groups of moving seats 25 are respectively hinged with connecting rod 2 17 and connecting rod 3 18. The bottoms of connecting rod 2 17 and connecting rod 3 18 are hinged on the same bottom plate 14. Four groups of universal wheels 15 are fixedly installed on the bottom of the bottom plate 14. Multiple groups of holes are opened on the outer side of the turntable 20 to lift the motor driver body 1 and keep it away from the ground where there may be water accumulation or moisture, thereby reducing the erosion of moisture to the internal electronic components of the driver and reducing the risk of short circuit and leakage.

[0025] In this embodiment, a fixed block 21 is fixedly installed on one side of the frame 13, a support rod 22 is slidably installed inside the fixed block 21, a fixed plate 24 is fixedly installed at the bottom of the support rod 22, and a spring 23 is fixedly installed between the bottom of the fixed block 21 and the top of the fixed plate 24.

[0026] In this embodiment, vertical grooves are provided on both inner walls of the frame 13, and both sides of the bottom plate 14 are slidably installed in the corresponding vertical grooves. By providing the vertical grooves, it can be ensured that the bottom plate 14 can slide stably on the inner wall of the frame 13, thereby improving stability and reducing shaking.

[0028] In this embodiment, the top end of the support rod 22 is movably inserted into the hole to ensure that there is no displacement during operation.

[0029] In this embodiment, during use, by pulling the fixed plate 24, the support rod 22 is driven to disengage from the turntable 20, the third spring 23 contracts, the locking of the turntable 20 is released, the turntable 20 is rotated to drive the bidirectional lead screw 19 to rotate, so that the two sets of second moving seats 25 can move relatively on the bidirectional lead screw 19, thereby driving the second connecting rod 17 and the third connecting rod 18 to rotate relatively, so that the bottom plate 14 slides at the bottom of the frame 13 to increase or decrease the distance between the frame 13 and the bottom plate 14. By arranging four sets of dampers 6, four sets of first springs 7, four sets of first connecting rods 8, four sets of first moving seats 11 and two sets of second springs 12 between the frame 13 and the motor driver body 1, shock absorption of the motor driver body 1 during operation is achieved. When the equipment leaks electricity, the leakage protector 4 will directly cut off the power supply of the equipment, and the warning light 3 starts to alarm, prompting the staff that the equipment leaks electricity, realizing the leakage warning and protection of the motor driver body 1.
