[0002] Low-voltage fixed switchgear is an electrical equipment used in power distribution systems. It is mainly used to control, protect and distribute electrical energy. It is used to access power supplies and connect various electrical equipment. Low-voltage fixed switchgear is usually composed of a casing, a circuit breaker, a grounding device, a control device, etc. It has reliable short-circuit protection and overload protection functions, and can ensure the safety of electrical equipment and personnel. Low-voltage fixed switchgear is widely used in industrial, commercial and residential buildings and other fields for the control and protection of power distribution systems. It has the characteristics of compact structure, easy installation, simple operation and high reliability. It is one of the indispensable important equipment in modern electrical systems. However, most of the low-voltage fixed switchgear in the prior art still have problems that need to be solved.

[0003] In the prior art, most low-voltage fixed switch cabinets do not have a protective structure at the base, which causes the low-voltage fixed switch cabinet to easily tilt and collapse when encountering an emergency (such as an external force impact), causing damage to the equipment inside the low-voltage fixed switch cabinet. The tilted low-voltage fixed switch cabinet may crush the staff and cause serious losses. Therefore, it is necessary to design a movable low-voltage fixed switch cabinet with a base protective structure to solve the above problems. Utility Model Content

The problem that most of the low-voltage fixed switch cabinets in the prior art mentioned in the background technology have no protective structure on the base, which causes the low-voltage fixed switch cabinet to tilt and collapse very easily when encountering emergencies (such as external force impact), causing damage to the equipment inside the low-voltage fixed switch cabinet, and the tilted low-voltage fixed switch cabinet may crush the staff and cause serious losses. The problem is achieved by facilitating movement, reducing the difficulty of movement, improving the stability of the equipment, and avoiding tilting and collapse due to external forces.

The first limiting rod 7 passes through the base 1, and the first limiting rod 7 is sleeved with a spring 9. Due to the use of a movable The technical means can retract the protective plate when moving the device and extend the protective plate when placing the device, so the occupied area can be reduced when moving the device, and the supporting area can be increased when placing the device, thereby preventing the equipment from tilting and collapsing. This effectively solves the problem that most of the low-voltage fixed switch cabinets in the prior art mentioned in the background technology have no protective structure on the base, which causes the low-voltage fixed switch cabinet to tilt and collapse very easily when encountering emergencies such as external force impact, causing damage to the equipment inside the low-voltage fixed switch cabinet, and the tilted low-voltage fixed switch cabinet may crush the staff and cause serious losses. The technical effect of facilitating movement and reducing the difficulty of movement is achieved, and the stability of the equipment can be improved to avoid tilting and collapse due to external force.

[0025] In this embodiment, the driving mechanism includes a motor 13, which is mounted on the top of the first mounting plate 2. The output shaft of the motor 13 is fixedly connected to the first bevel gear 14, the first bevel gear 14 is meshingly connected to the second bevel gear 15, and the bottom of the second bevel gear 15 is fixedly connected to a screw rod 18, which passes through the first mounting plate 2 and the second mounting plate 3.

[0026] In this embodiment, a connecting rod 16 is fixedly connected to the top of the second bevel gear 15 , a sleeve 17 is sleeved on the top of the connecting rod 16 , and the top of the sleeve 17 is fixedly connected to the base 1 .

[0027] In this embodiment, four second limit rods 11 in a square layout are fixedly connected to the bottom of the first mounting plate 2, and the four second limit rods 11 all pass through the second mounting plate 3. The top of the second mounting plate 3 is fixedly connected to a limit ring 10, and the limit ring 10 is sleeved on the second limit rods 11.

[0028] In this embodiment, a low-voltage fixed switch cabinet body 19 is fixedly connected to the top of the base 1 .

[0029] In this embodiment, a sleeve plate 12 is fixed on the top of the second mounting plate 3 , and the sleeve plate 12 is sleeved on the screw rod 18 .

[0030] Working principle: after moving the device to the placement position, the motor 13 can be started, and the output shaft of the motor 13 will drive the first bevel gear 14 to rotate, and the first bevel gear 14 will drive the second bevel gear 15 to rotate, and the second bevel gear 15 will drive the screw rod 18 to rotate, and the screw rod 18 will drive the sleeve plate 12 to rise, and the sleeve plate 12 will drive the second mounting plate 3 to rise, and the second mounting plate 3 will drive the universal wheel 20 to rise until the bottom of the base 1 touches the ground, and when the second mounting plate 3 rises, it will drive the limiting ring 10 to rise along the second limiting rod 11. Due to the restriction of the second limiting rod 11, the second mounting plate 3 will not deviate when rising, and when the second bevel gear 15 rotates, it will also drive the connecting rod 16 to rotate. Through the mutual cooperation between the connecting rod 16 and the sleeve 17, the second bevel gear 15 will not deviate when rotating. When the second mounting plate 3 rises, it will contact the hypotenuse of the trapezoidal plate 5. At this time, if the second mounting plate 3 continues to rise, the four trapezoidal plates 5 will move, and the trapezoidal plate 5 will drive the protective plate 6 to move, and the four protective plates 6 will extend, thereby improving stability and preventing the low-voltage fixed switch cabinet body 19 from tipping over. When the protective plate 6 moves, it will drive the first limit rod 7 to move, and the first limit rod 7 will drive the square plate 8 to move, which can cause the spring 9 to contract. When it is necessary to move the device again, the output shaft of the motor 13 can be reversed to lower the second mounting plate 3, that is, to lower the universal wheel 20, and the second mounting plate 3 will no longer contact the trapezoidal plate 5, so the spring 9 will stretch out, which can retract the protective plate 6, thereby reducing the range occupied by the device and facilitating the movement of the device.
