Description

Technical Field

[0001] The invention belongs to the technical field of electrical cabinets, in particular to an electrical control cabinet. Background Art

[0002] Electrical control cabinets are an important part of electrical equipment and automation systems, and are widely used in industries such as industry, construction, transportation, and energy. They centrally manage and control electrical equipment, protect components, and achieve automated control. Control cabinets are usually made of metal or plastic, and contain components such as circuit breakers, contactors, relays, and PLCs, and are equipped with a human-machine interface (HMI) for operation. According to their functions, they can be divided into distribution cabinets, control cabinets, operating cabinets, and explosion-proof control cabinets, and are widely used in manufacturing, building automation, and energy industries.

[0038] Working principle: When the electrical control cabinet is used, first press the bottom end of the handle 310 forward to rotate the top end of the first engaging rod 311 outward and cancel the engagement with the engaging groove 37, so that the first slider 38 can slide outside the slide rail 36, thereby adjusting the height of the first slider 38 and the mounting platform 4, and then install the component on the mounting frame 43, and then pull the fixing frame 46 downward to make the second limiting column 45 fit with the inner top end of the fixing frame 46, so that the fixing frame 46 can surround The second locking rod 49 is pulled upwards, and the slide groove 44 on the mounting frame 43 is aligned with the locking column 42, and the mounting frame 43 is pushed into the inner side of the first limiting column 41. Then, the fixing frame 46 is turned downwards, and the fixing frame 46 is sleeved on the outer side of the locking column 42, and the fixing frame 46 and the second locking rod 49 are loosened. First, the second locking rod 49 is pushed downwards with the fixing frame 46 as the stress point through the third spring 48, so that the second locking rod 49 is locked with the locking column 42. The columns 42 are engaged with each other, and then the third spring 48 uses the second engaging rod 49 as the stress point to push the fixing frame 46 upward, so that the fixing frame 46 is engaged with the bottom end of the engaging column 42, and the mounting frame 43 and the first limiting column 41 are fixed to complete the installation. When external vibration occurs during use, the impact force generated by the vibration is transmitted to the first transmission frame 21 through the main cabinet 1 and the mounting foot 2, and then the impact force is transmitted to the first transmission rod 22 and the second transmission rod 23 through the first transmission frame 21. At the same time, the first transmission rod 22 and the second transmission rod 23 respectively drive the damping rod 24 and the damping cylinder 25 to move in opposite directions at the same time, so that the damping rod 24 slides up and down in the damping cylinder 25, and through the large friction between the damping rod 24 and the damping cylinder 25, the impact force is converted into heat and dissipated into the air, so as to achieve the purpose of shock absorption. At the same time, through the deformation of the first spring 26 itself, part of the impact force is converted into heat and dissipated into the air for shock absorption.
