The handle is movably assembled at the base so that the buckle and auxiliary hook on one side of the handle protrude outside the base for locking or unlocking by hook and latch, thereby achieving the purpose of easy operation of the lock and latch. Prior Technology
[0002] Note that with the continuous advancement and development of electronic technology, computer technology brings convenience, comfort, speed, and high efficiency to people's lives and work. Therefore, the application functions of electronic technology and computer systems are becoming increasingly powerful and their scope is expanding. Besides personal computers, centralized management systems, such as industrial computer rooms, building central control systems, automated factory operation systems, and audio-visual playback central processing control systems, all connect multiple computer hosts, servers, and workflow conversion systems simultaneously through centralized management, and are assembled in a layered manner within large... Inside the electronic equipment chassis, there are stacked boxes arranged in upper and lower layers. The boxes can be pulled out or pushed out from the side of the electronic equipment chassis for the assembly or maintenance of various computer operating systems. Because multiple operating host systems are combined, when various computer operating systems need to be tested or updated, the boxes of different layers must be pulled out of the electronic equipment chassis one by one to facilitate testing or related maintenance. Therefore, the many stacked boxes assembled inside the electronic equipment chassis are equipped with simple fastening structures to facilitate the assembly of each box inside the chassis or the pulling out of the chassis.
[0003] The stacked chassis assembled inside electronic equipment sets house various electronic and circuit systems. Besides basic word processing and application execution, they also allow for internet access to search for information, making computers essential in daily life and work. In addition to peripherals, each chassis features removable slots for expanding data storage and ensuring data security. These slots allow for easy connection of removable hard drives, CD-ROM drives, or multimedia players, expanding application possibilities without encroaching on the chassis's internal space. However, these slots are fixed frames, and the assembly path and space are often obstructed by handles on the outside of the chassis. This inconvenience makes plugging and unplugging electronic products difficult and requires improvement.
[0004] Therefore, how to solve the problems and troubles of the current stacked electronic device chassis, such as the inconvenience of pulling out and pushing various boxes, and the trouble and shortcomings of the handles on each box for pulling out that easily block the internal electronic circuits and the assembly path and space of external electronic products, is the direction that relevant manufacturers in this industry are eager to research and improve.

[0017] Furthermore, the base 1 of the present invention, assembled in the accommodating space 100, has a through-type groove 110 for the positioning member 12 to pass through. A horizontally penetrating locking hole 120 is provided above the positioning member 12, and an elastic support member 121 is fitted on its top. The other side of the elastic support member 121 abuts against the inner surface of the cover plate 1001. Triangular channels 1101 extending outwards are provided on both sides of the groove 110. A sliding rod 122 can be inserted into one channel 1101, through the locking hole 120, and then into the other channel 1101, thus confining the positioning member 12 in the groove 110 and positioning it relative to the positioning member 12 of the switch 11 in the accommodating space 100. The base 1 has a positioning through hole 1005 extending to the assembly space 10, allowing the positioning rod 123 at the bottom of the positioning member 12 to move and extend at the positioning through hole 1005. The cover 24 has a limiting hole 244 located at the positioning through hole 1005, allowing the positioning rod 123 at the bottom of the positioning member 12 to extend and retract at the positioning through hole 1005 and also enter and exit the limiting hole 244, so as to hold or retract at the side of the auxiliary hook 23. Furthermore, one side of the shaft 13 of the base 1 can be locked to the bottom of the limiting groove 101 by screw 133, and the other side can also be locked to the cover 24 by screw 133, so as to limit the shaft 13 between the limiting groove 101 of the base 1 and the cover 24.
[0018] In actual operation, the rotary fixing device of the present invention can be pressed on the pressing side 111 of the switch 11 of the base 1. The sliding rod 122 is guided obliquely by the two channels 1101 on the other side of the switch 11 to drive the positioning member 12 to move vertically upward and move the positioning rod 123 at the bottom of the positioning member 12 to move away from the limiting hole 244 of the cover 24. Then the handle 22 can be turned to move the buckle 21 on one side to swing. At the same time, the auxiliary hook 23 is driven to swing in a fan shape toward the buckle 21 to achieve the purpose of buckling and locking or unlocking the auxiliary buckle 21.
[0019] Furthermore, in practical application, the rotary fixing device of the present invention can assemble at least one base 1 and handle 2 at the side or near the corner of a preset chassis 3 (the preset chassis 3 can be a computer motherboard, hard disk, blade server, electrical control box, or industrial computer circuit box, etc.). This allows at least one base 1, handle 2, and preset chassis 3 to be assembled into a preset frame 4 (the preset frame 4 can be a computer chassis, server chassis, electrical chassis, or industrial computer chassis, etc.). The preset frame 4 has at least one abutment wall 41, and a snap-fit groove 40 is provided on the side near at least one abutment wall 41. The handle 2 assembled in the assembly space 10 of the base 1 is then inserted into at least one snap-fit groove 40 of the preset frame 4 with a fastening member 21, so that the preset frame 4 is installed in the preset chassis 3, and a locking limit is formed by at least one base 1 and handle 2.
[0020] To remove the preset chassis 3 from the preset rack 4, apply pressure to the pressing side 111 of the switch 11 on the base 1. The switch 11 pushes the reset elastic member 113 against the wall panel 1004 inside the accommodating space 100, so that the positioning member 12 assembled in the slide groove 110 of the switch 11 is pulled by the sliding rod 122. The sliding rod 122 moves obliquely upward along the inclined channel 1101 on both sides of the slide groove 110, driving the positioning member 12 to rise. The elastic support member 12 at its top... 1. Pressing against the inner surface of the cover plate 1001, it limits the positioning member 12 to prevent it from swinging or shifting. At the same time, the positioning rod 123 at the bottom of the positioning member 12 is also raised and disengaged from the limiting hole 244 of the cover body 24. Then, the handle 22 can be turned to drive the auxiliary hook 23 on the buckle 21 to slide along the guide rail 242 of the cover body 24 through the sliding rod 251 of the swing member 25. The sliding rod 251 rises and slides along the gathering part 2421 of the guide rail 242 towards the first rail groove 2422. This causes the sliding rod 251 to move to the stopping part 2423 and stop. At this time, the hook body 232 of the auxiliary hook 23 is held against the wall 41 of the preset frame 4, and the handle 2 generates (counterclockwise) steering force, and also pushes the limiting elastic member 131. This allows the sliding rod 251 of the swing member 25 of the auxiliary hook 23 to exit the stopping part 2423 and move to the second track groove 2424 on the other side, and then slide obliquely back to the original gathering part 2421 position. It also assists the handle 22 to drive the buckle 21 to rotate in a fan shape and exit the preset position. At the latching slot 40 of the frame 4, the handle 22 can be moved to be parallel to the preset frame 4, so that the base 1, handle 2 and preset housing 3 can be easily pulled out from the preset frame 4. The handle 2 can be pushed back by the elastic reaction force of the limiting elastic member 131, so that the handle 22 is parallel to the side of the preset housing 3, and can be held against the wall 41 by the auxiliary hook 23. This makes it easier and more convenient to operate the handle 22 to unlock it.
