Description

Technical Field

[0001] The present invention relates to the field of electromechanical equipment protection equipment, and in particular to a quick-disassembly buckle for an electromechanical equipment protective shell, which realizes quick disassembly and position adjustment of the protective shell through a sliding card slot and a multi-angle locking mechanism. Background Art

[0002] In the field of electromechanical equipment, the cover and body of a protective enclosure are typically connected and secured using mechanical clips, and the cover and body are usually separate structures. Traditional equipment clips are mostly fixed installations, and the locking position cannot be adjusted according to device size or installation scenario, resulting in poor applicability. Conventional clips also require tools or multiple steps to disassemble, and cannot be opened and closed quickly, seriously affecting equipment maintenance efficiency.

[0003] Some buckles are prone to loosening due to vibration during long-term use, resulting in a decrease in the sealing of the protective housing and affecting the protective performance of the equipment. At the same time, most buckles require two-handed operation and cannot be opened from one side, making it difficult to meet the needs of emergency maintenance or one-handed operation. In addition, the current equipment disassembly buckles are only used as locking components. Since the box body and the box cover are mostly separate, when the box cover needs to be opened, a hinge structure needs to be installed separately. In other words, the current box cover locking buckles cannot replace the hinge function. If a hinge is installed, the opening direction of the cover is completely fixed during use, and the cover can only be opened from the side opposite the hinge. The housing box for installing electromechanical equipment is generally heavy, and when opening the cover, the person can only adjust the standing direction to the side opposite the hinge. In other words, the person needs to go around to the fixed opening side to operate. Since the installation area of ​​electromechanical equipment is usually relatively narrow, only setting a lock as a switch structure on the side opposite the hinge will increase the limitations of the equipment and make it inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide a quick-disassembly buckle for the protective shell of an electromechanical equipment in order to solve the above-mentioned problem. An upper slide groove and a lower slide groove are set as the support structure of two groups of slides.
