Description

Cabinet door structure convenient to dismantle and high-voltage inverter cabinet body Technical Field The application belongs to the technical field of electrical equipment, and particularly relates to a cabinet door structure convenient to detach and a high-voltage frequency converter cabinet body. Background In the design and application of the high-voltage frequency converter cabinet body, the cabinet door is used as a key component for equipment protection and operation maintenance, and the structural design of the cabinet door directly influences the safety and operation maintenance efficiency of the equipment. Conventional high-voltage inverter cabinet doors are generally made of sheet metal and are connected with a cabinet frame through screws. Specifically, a through hole is formed in the cabinet door in advance, one end of the screw, which is opposite to the end head of the screw, is inserted into the cabinet body, a gap is reserved between the end head and the cabinet body, and the through hole in the cabinet door is required to be aligned with the screw during installation. However, in the prior art, the diameter of the through hole of the cabinet door is only slightly larger than the diameter of the end head of the screw. Although the design can ensure the stability of the cabinet door after being hung in the gap, the cabinet door has the following defects: 1. The installation alignment is difficult, and in equipment or field maintenance process, if debugging, maintenance or emergency need frequent switching, operating personnel need accurate alignment cabinet door phi through-hole and the end of screw, and on the heavy circumstances of cabinet door, the staff often can't install fast smoothly, and operating efficiency is low. 2. The disassembly efficiency is low and unsafe, when the cabinet door is temporarily disassembled by replacing elements in the cabinet or cleaning foreign matters, the cabinet door is difficult to separate from the screw rapidly due to too small clearance of the through hole, and the cabinet door is required to be manually supported during separation, so that the risk of cabinet door falling exists and the safety of staff is influenced. 3. The cabinet door is hung on the screw for a long time, so that the abrasion to the cabinet door is large, the service life of the screw is short, and the maintenance cost of staff is high. Disclosure of utility model The application aims at overcoming the defects of the prior art, adopts a mode of arranging a calabash hole on a cabinet door, designs a cabinet door structure convenient to detach and a high-voltage frequency converter cabinet body, can flexibly install and detach the cabinet door under the scenes of assembly, field maintenance, cleaning of foreign matters in the cabinet and the like, and can improve the operation efficiency and the operation safety of staff. In order to achieve the above purpose, the following technical scheme is adopted: The utility model provides a cabinet door structure convenient to dismantle, includes cabinet door, screw, be equipped with the calabash hole on the cabinet door, the internal diameter of big end one end is greater than on the calabash hole the end of screw, the internal diameter of the little end of calabash hole is greater than the external diameter of screw, the internal diameter of the little end of calabash hole is less than the external diameter of the end of screw. Preferably, a gap is formed in the circumferential surface between the two ends of the screw and close to the end of the screw, and the width of the gap is larger than the thickness of the cabinet door. Preferably, the cabinet door is provided with a 7-shaped buckle below the gourd hole, one end of the 7-shaped buckle, which is provided with a transverse part, faces towards the gourd hole, one end of the 7-shaped buckle, which is provided with a vertical part, faces away from the gourd hole, the transverse part of the 7-shaped buckle is perpendicular to the cabinet door, and the upper end of the vertical part of the 7-shaped buckle is fixedly connected with one end of the 7-shaped buckle, which faces away from the cabinet door. Preferably, a first magnet block is arranged below the calabash hole on the cabinet door, and the first magnet block is fixedly connected with the cabinet door. Preferably, the width of the opening is 2-5mm larger than the thickness of the cabinet door.
