Description

Anti-fool rotating buckle

The present invention provides a foolproof rotating buckle, in particular, a through hole is provided at the sleeve of the preset air guide corresponding to the foolproof rotating buckle during chassis assembly, and a supporting block is provided adjacent to the lever portion corresponding to the through hole. When the preset air guide is forced to move downward, the lever portion of the sleeve contacts the bottom surface of the supporting block and causes the sleeve to rotate downward to an inclined position under force, and the foolproof portion penetrates the through hole upward from a vertical position and rotates to an approximately horizontal position. At the same time, the height of the foolproof portion in a horizontal state is lower than the top of the side plate of the chassis, and when the cover is assembled on the preset chassis, the overall assembly can be completed without interference from the foolproof portion of the sleeve, so that a foolproof mechanism can be achieved when assembling the preset air guide in the preset chassis, which helps to improve the assembly yield of the preset chassis.

According to the continuous innovation and progress of computer technology, the application of computers or various electronic and electrical products has become more extensive, and the functions of use have continued to expand and increase. In computers or electronic and electrical products, the circuit layout, central processing unit, chip and various electronic components used to process various operations, calculations, executions, analysis and other functions must also be appropriately expanded and increased. Therefore, the circuit boards equipped with circuit layout, central processing unit, chip and various electronic components will also expand and increase the area and scope of use with the application functions of computers; however, in computers or electronic and electrical products, the circuit layout, central processing unit, chip and various electronic components will also expand and increase the area and scope of use. When the internal space of electrical products is limited, the circuit boards that control the operation of computers or electronic and electrical products cannot be expanded. In order to solve the problem of circuit board application in the server room, some operators use multiple screws to lock multiple partitions inside the chassis and multiple screws to lock the circuit boards on each partition. However, this circuit board assembly method not only takes a long time to assemble, but also requires hand tools to disassemble the partitions and circuit boards layer by layer during maintenance, which is very labor-intensive and time-consuming.

Furthermore, since the circuit board in the chassis generates a lot of heat during operation, an air duct must be installed between the chassis and the circuit board to enhance the air cooling effect. However, since the air duct is not a standard component of the chassis (in other words, it is an optional component), it is easy to miss the assembly during the chassis assembly process. After the quality control inspection, the chassis needs to be disassembled and reassembled, which reduces the assembly yield and increases the working hours. Therefore, how to form a fool-proof mechanism when assembling the air duct in the chassis has become a problem that the industry wants to develop and solve.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information and, after multiple evaluations and considerations, designed the invention of this fool-proof rotating buckle.

The main purpose of the present invention is to provide a foolproof rotating buckle, which is assembled on the inner wall of at least one side plate of a preset case, and the preset case is equipped with a preset air guide cover fixed from top to bottom, and the preset air guide cover is supported by the sleeve of the foolproof rotating buckle and rotated, so that the preset air guide cover is not interfered by the top support of the foolproof rotating buckle during the installation process and the assembly is completed.

An elastic member is sleeved on the outside of the sleeve body and the two ends of the elastic member are respectively positioned in the housing body and the annular body of the base. The positioning member has a limiting wall inside for the coupling part of the rotating shaft to penetrate and fix. The outer edge of the sleeve body is protruded to form a foolproof part located above and a pull part adjacent to the foolproof part and for the preset air guide cover to abut and rotate. The preset air guide cover is provided with a through hole at the corresponding sleeve body, and a support block is provided at the corresponding pull part adjacent to the through hole. When the preset air guide cover is forced to move downward, the pull part of the sleeve body contacts the bottom surface of the support block and causes the sleeve body to rotate downward to a tilted position under force, and the foolproof part penetrates the through hole from a vertical position and rotates to an approximately horizontal position. At the same time, the height of the foolproof part in a horizontal state is lower than the top of the side plate of the chassis. When the cover is assembled on the preset chassis, the overall assembly can be completed without interference from the foolproof part of the sleeve body. The foolproof mechanism can be achieved when assembling the preset air guide cover in the preset chassis, which helps to improve the assembly yield of the preset chassis.

The secondary purpose of the present invention is that the annular body of the base has four positioning grooves arranged at an angle of about 90 degrees, and the positioning grooves are used to position the fixed end of the elastic member and to support and position at least one push rib protruding from the inner wall of the accommodating chamber of the sleeve.
