When the quick-release accessory of the present invention is to be assembled, the latch member 3 of the assembled rotary reset member 31 is first placed on the shaft 1141 of the base 11 to form a position, and then the locking block 2 installed in the elastic member 23 is penetrated and positioned in the two supporting grooves 1131 of the accommodating space 113, and then the rod 41 of the operating handle 4 is aligned with the sliding path 111, the guide groove 21 and the guide chamber 22. Assembly; at the same time, the guide body 416 is inserted into the slide groove 261, and the handle 42 of the operating handle 4 is exposed on the base 11 and the stopper 417 is held against the top of the outer shell 1. Finally, the multiple fixing holes 120 of the cover plate 12 are aligned with the multiple through holes 110 of the base 11, and the multiple fasteners 13 composed of multiple rivets are inserted and fixed by riveting. The assembly of the chassis quick-release accessories is completed by the above.

Please refer to Figures 7 to 12, which are respectively a side view and cross-sectional view of the present invention in an unlocked and sliding state, a side view and cross-sectional view in a locked state, another side view and cross-sectional view in an unlocked and sliding state, another side view and cross-sectional view in a locked state, a three-dimensional schematic diagram of a cabinet, and an embodiment diagram, and refer to Figures 1 and 2 at the same time. When the chassis quick-release fittings of the present invention are implemented, two sets of chassis quick-release fittings need to be respectively locked into the screw grooves at the front ends of the left and right sides of the preset chassis 5 using the preset multiple screws exposed on the cover plate 12, and then the operating handle 4 is adjusted to pull the rod 41 away from the outer shell 1 and make the rod 41 partially exposed from the outer shell 1, so that the locking part 411 can be pushed into the guide chamber 22, and the locking part 411 can be locked by the locking part 411. The abutting edge 4111 of the portion 411 is tightly abutted against the slope 221 of the guide chamber 22; at the same time, the locking block 2 forms a linear slide in an inclined downward direction through the guide body 416 in the slide groove 261 to form a double-guided linear slide structure of the locking block 2, so that the locking block 2 can be pushed and the elastic member 23 can be compressed to form an unlocked state (as shown in Figures 1, 7, and 9). At the same time, after the locking portion 411 is pushed back from the rotating space 114 to the guide chamber 22 of the locking block 2, the locking edge 331 of the latch 3 lacks the support of the locking area 4113 of the locking portion 411, and the rebound force of the rotating reset member 31 causes the large swing arm 32 to partially rotate and extend out of the outer shell 1. Next, the rear end of the preset case 5 assembled with the case quick release accessories and in the unlocked state (where the case quick release accessories are not assembled) is first pushed into the cabinet 6 as shown in FIG. 11, and the large swing arm 32 extending from the bottom latch 3 of the case quick release accessories is retracted into the rotation space 114 by the push groove 61, and only the inner wall surface of the support edge 321 at the end of the large swing arm 32 is left to fit the base 11, and the outer wall surface of the support edge 321 extending from the outer shell 1 forms a guide rail and fits the surface of the push groove 61, and the support edge 321 in the process of pushing is limited by the limit plate 62 extending obliquely from the push groove 61. It will not derail, and the side length of the preset chassis 5 is slightly shorter than the length of the push groove 61. Therefore, when the rear end of the preset chassis 5 is pushed to the end of the push groove 61, the locking block 2 of the chassis quick-release accessory can be exactly aligned with the latch hole 60 of the cabinet 6 provided on the vertical wall surface, and the operating handle 4 can be pushed toward the outer shell 1, so that the locking portion 411 is partially pushed out of the guide chamber 22 and enters the rotating space 114. When the locking block 2 is pushed by the elastic member 23 and linearly slides obliquely upward along the guide body 416 of the operating handle 4, it slides out from the accommodating space 113 and is latched into the latch hole 60 of the cabinet 6 to form a locked state. At the same time, after the locking portion 411 is pushed from the guide chamber 22 of the locking block 2 to the rotating space 114, the locking area 4113 of the locking portion 411 extends into the inner side of the small swing arm 33 of the latch 3 and abuts against the locking edge 331, so that the latch 3 can be in a locked state that will not swing (as shown in Figures 2, 8, and 10). Through the above operation, the preset chassis 5 can be quickly fixed in the cabinet 6.

According to the above, when the preset case 5 is to be pulled out of the cabinet 6, it is only necessary to adjust the operating handle 4 to pull the rod 41 away from the outer shell 1 and partially expose the rod 41 from the outer shell 1, so that the locking block 2 is retracted from the latch hole 60 of the cabinet 6 into the accommodating space 113 to form an unlocked state; at the same time, the large swing arm 32 of the latch 3 partially rotates and extends out of the outer shell 1 and the abutting edge 321 abuts against the surface of the push groove 61, so that the front end of the preset case 5 is abutted by the latch 3 and slightly raised, and the preset case 5 in a tilted state is easier to apply force to be pulled out of the cabinet 6. In order to ensure the smoothness of the force application operation in the narrow space of the cabinet 6, the operating part 422 needs to be rotated (for example: the operating part 422 located on the left side of the operating handle 4 of the default case 5 is rotated from the 12 o'clock direction to the 3 o'clock direction; the operating part 422 located on the right side of the operating handle 4 of the default case 5 is rotated from the 12 o'clock direction to the 9 o'clock direction), and the specific operation method of rotating the operating part 422 is: apply force to the operating part 422 in the 12 o'clock direction to make it rotate, the positioning block 414 before the force is applied is engaged with the first positioning groove 4211, and the operating part 422 is rotated to the second positioning groove 4212 located at the 3 o'clock or 9 o'clock position, and the step-shaped positioning The block 414 is located on the outer wall of the upper step block and sequentially rubs against the inner wall of the interference convex block 4213 to form a segmented feel. Finally, the positioning block 414 is engaged with the second positioning groove 4212 to achieve the purpose of turning the operating part 422 and facilitating the pulling out of the preset chassis 5. After the preset chassis 5 is pulled out of the cabinet 6, the operating parts 422 of the operating handles 4 on both sides of the preset chassis 5 are adjusted back to the twelve o'clock position and engaged (that is, the positioning block 414 is moved out of the second positioning groove 4212 and engaged with the first positioning groove 4211 by rotating the operating part 422). The above operation can achieve the purpose of quickly removing the preset chassis 5 from the cabinet 6.

From the disclosure of Figures 1 to 12 above, it can be understood that the main feature of the present invention is to propose a chassis quick-release accessory combined with two sides of the preset chassis 5, and the operating handle 4 can be pushed toward the outer shell 1, so that the locking block 2 extends out and locks in the latch hole 60 of the cabinet 6, so that the preset chassis 5 is quickly fixed to the cabinet 6; and the operating handle 4 is pulled away from the outer shell 1, and the latch hole 60 of the cabinet 6 is retracted into the accommodating space 113 to form an unlocked state, so as to achieve the purpose of quickly removing the preset chassis 5 from the cabinet 6. The present invention is applied in the field of installing, disassembling and maintaining computer components in the server room, and has excellent practicality, so a patent application is filed to seek patent protection.

The above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the present invention's specification and drawings should be included in the patent scope of the present invention and should be stated.

In summary, the above-mentioned chassis quick-release accessories of this invention can truly achieve their functions and purposes when used.
