[0037] An embodiment of the present application provides a tool-free fixing device, which is applied to a server, such as Figure 1 and Figure 2As shown in the figure, a bracket 1 is arranged inside the server, and the side wall of the bracket 1 is detachably connected to a fixed column 2. A buckle member 3 and an adjusting member 4 are rotatably sleeved on the fixed column 2. Among them, the buckle member 3 and the adjusting member 4 are rotatably sleeved on the fixed column 2 coaxially. One end of the buckle member 3 is rotatably connected to the fixed column 2, and the other end is a movable end. And a receiving space for receiving the product 5 to be fixed is formed between the movable end and the bracket 1. One end of the adjusting member 4 is coaxially and rotatably connected to the buckle member 3 on the fixed column 2, and the other end is an adjusting end 6. At the same time, the adjusting end 6 is arranged closer to the product 5 to be fixed than the movable end. By adjusting the rotation of the adjusting end 6 around the fixed column 2, the movable end is driven to press and position the product 5 to be fixed in the receiving space; in this embodiment, the product 5 to be fixed is an expansion card. Among them, the bracket 1 is used to receive the PCIE board 17. The PCIE board 17 is installed in the bracket 1 through the open end of the bracket 1, so as to realize the fixed installation of the expansion card at the tail end of the bracket 1 through this tool-free fixing device, and to provide more expansion slots for the PCIE board 17 through the expansion card.

[0038] As Figure 3 and Figure 4 As shown in the figure, the buckle member 3 includes a flap main body 301. The movable end includes a driving piece 302 and a pressing piece 303 fixedly connected to one end of the flap main body 301. The driving piece 302 and the pressing piece 303 are integrally formed with the flap main body 301, and the driving piece 302 and the pressing piece 303 are coaxially arranged, and a preset angle is formed between the driving piece 302 and the pressing piece 303. Among them, the pressing piece 303 and the driving piece 302 are arranged in sequence along the direction away from the product 5 to be fixed, and the adjusting end 6 is arranged closer to the product 5 to be fixed than the pressing piece 303, so as to facilitate the adjusting end 6 to drive the driving piece 302 to adjust the pressing position of the buckle member 3; at the same time, when only one buckle member 3 is installed on the fixed column 2, at this time, the driving piece 302 can also be adjusted to drive the pressing piece 303 to position the product 5 to be fixed.

[0039] It should be noted that the preset angle between the driving piece 302 and the pressing piece 303 is set to 1° to 120°. Specifically, the preset angle between the driving piece 302 and the pressing piece 303 includes but is not limited to 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110° or 120°.

[0040] As Figure 4As shown in the figure, in order to further improve the positioning effect of the product 5 to be fixed by the crimping piece 303 on the movable end, a positioning block 7 is fixedly connected to the side of the crimping piece 303 close to the product 5 to be fixed. The positioning block 7 is integrally formed with the crimping piece 303. A positioning hole 501 corresponding to the position of the positioning block 7 is provided on the product 5 to be fixed. The adjusting end 6 is rotated around the fixed column 2 so that the positioning block 7 is inserted into the positioning hole 501, further strengthening the positioning of the product 5 to be fixed.

[0041] In this embodiment, as Figure 3 shown, one end of the retaining piece body 301 of the buckle piece 3 is fixedly connected to the first curled edge 3011, and the first curled edge 3011 forms a first curled edge hole 3012. The buckle piece 3 is rotatably sleeved on the fixed column 2 through the first curled edge hole 3012, and the other end is fixedly connected to the driving piece 302 and the crimping piece 303. Among them, two first curled edges 3011 are provided at intervals at the end of the retaining piece body 301. The two first curled edges 3011 are arranged along the length direction of the fixed column 2. A hollow elastic member 8 is movably installed at the interval between the two first curled edges 3011. The middle part of the elastic member 8 passes through the fixed column 2. The two ends of the elastic member 8 are respectively fixedly connected to the first support rod 801 and the second support rod 802. The first support rod 801 and the second support rod 802 are respectively located on both sides of the fixed column 2, and the first support rod 801 and the second support rod 802 respectively extend along the direction away from the central axis of the fixed column 2. The first support rod 801 is clamped to the retaining piece body 301. A card slot 9 corresponding to the second support rod 802 is provided on the bracket 1. A plurality of card slots 9 are arranged at intervals in the height direction of the bracket 1. When the buckle piece 3 is sleeved on the fixed column 2, the second support rod 802 is clamped to the card slot 9.

[0042] As Figure 3 and Figure 5 shown, the adjusting member 4 includes a second curled edge 402 fixedly connected to the adjusting end 6. The second curled edge 402 is integrally formed with the adjusting end 6 and curls inward along one side edge of the adjusting end 6 to form a second curled edge hole 403. The second curled edge hole 403 is rotatably sleeved on the fixed column 2 so that the adjusting member 4 is rotatably sleeved on the fixed column 2 through the second curled edge hole 403. An adjusting piece 601 is fixedly connected to the adjusting end 6. The adjusting piece 601 is coaxial with the adjusting end 6 and is set at a preset angle. At the same time, the adjusting end 6 is located on the side closest to the product 5 to be fixed compared to the movable end.

[0043] It should be noted that the preset angle between the adjusting end 6 and the adjusting piece 601 is set to 1° to 120°. The specific preset angles between the adjusting end 6 and the adjusting piece 601 include but are not limited to 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110° or 120°.

[0044] With the above settings, before positioning the product 5 to be fixed by adjusting the buckle member 3 through the adjusting member 4, it is first necessary to pass the buckle member 3 and the adjusting member 4 through the fixing post 2. Specifically, it includes: the fixing post 2 is detached from the bracket 1 and passed through the fixing post 2 along the curling hole of the buckle member 3 from the bottom end of the fixing post 2. At the same time, the elastic member 8 is placed between the two first curling edges 3011, and the first curling hole 3012 is aligned with the middle through hole of the elastic member 8, so as to realize that the hollow elastic member 8 and the first curling edge 3011 are coaxially passed through the fixing post 2; then the second curling hole 403 is passed through the bottom end of the fixing post 2 and sleeved on the fixing post 2, the adjusting piece 601 is rotated, and the adjusting end 6 is arranged closer to the product 5 to be fixed than the movable end. At the same time, the first rod 801 on the elastic member 8 is clamped on the baffle body 301, and the second rod 802 is clamped in the slot 9 at the same time, so as to realize the position installation of the buckle member 3 and the adjusting member 4.

[0045] It should be noted that in this embodiment, the elastic member 8 is set as a torsion spring. Through the setting of the elastic member 8, an initial state elastic force can be provided for the buckle member 3, that is, the pressing piece 303 of the buckle member 3 always maintains a movement trend towards the side close to the accommodating space in the initial state, so as to strengthen the positioning effect of the buckle member 3 on the product 5 to be fixed.

[0046] In this embodiment, as Figure 5 shown, the adjusting end 6 in the adjusting member 4 is strip-shaped, and when the adjusting member 4 is installed on the fixing post 2, the length direction of the adjusting end 6 extends along the length direction of the fixing post 2, and the projection of the driving piece 302 on the plane where the central axis of the fixing post 2 is located partially or completely covers the projection of the adjusting end 6 on the plane where the central axis of the fixing post 2 is located, so as to ensure that the adjustment range of the adjusting end 6 can cover the position where the driving piece 302 is located and ensure the reliability of the adjustment process of the adjusting member 4 on the buckle member 3.

[0047] As Figure 3 shown, since the number of slots provided by the expansion card needs to be adjusted according to the number of PCIE boards during the installation of the expansion card, in order to provide more slots in this embodiment, a plurality of expansion cards need to be installed at the end of the bracket 1. In order to facilitate the simultaneous clamping and fixing of a plurality of expansion cards and improve the convenience of tool-free adjustment, when a plurality of buckle members 3 are sleeved along the length direction of the fixing post 2, a plurality of buckle members 3 are sequentially installed on the fixing post 2 along the length direction of the fixing post 2, and the projections of the driving pieces 302 of the plurality of buckle members 3 on the plane where the central axis of the fixing post 2 is located partially or completely cover the projection of the adjusting end 6 on the plane where the central axis of the fixing post 2 is located, so as to realize that when the adjusting end 6 rotates around the fixing post 2, a plurality of buckle members 3 can be adjusted simultaneously, so as to facilitate the crimping and positioning of a plurality of products 5 to be fixed.

[0048] Further, in order to prevent the buckle 3 threaded on the fixed column 2 from sliding during use and causing its position to deviate, the side wall of the fixed column 2 is fixedly connected with a first convex block 10 and a second convex block 11. The cross-section of the first convex block 10 is an oblique right triangle. When the buckle 3 is threaded along the fixed column 2 to a preset position, the first convex block 10 is embedded between the hole of the first curled edge 3011 of the buckle 3 and the fixed column 2, so as to position the installed buckle 3 through the first convex block 10. And a plurality of first convex blocks 10 are arranged along the length direction of the fixed column 2 to stop a plurality of buckles 3. The second convex block 11 has the same structure as the first convex block 10. When the adjusting member 4 is threaded along the fixed column 2 to a preset position, the second convex block 11 is embedded between the hole of the second curled edge 402 of the adjusting member 4 and the fixed column 2, so as to position the installed adjusting member 4 through the second convex block 11.

[0049] As Figure 3 shown, the fixed column 2 in this embodiment is detachably installed at one end of the bracket 1 through a connecting member. Specifically, the top end of the fixed column 2 is fixedly connected with an installation column 12. The installation column 12 is a stepped column, and its diameter is larger than the column body part of the fixed column 2. An installation hole 13 corresponding to the installation column 12 is provided on the bracket 1. The installation column 12 is threaded into the installation hole 13 so that the top end of the fixed column 2 and the bracket 1 are fixed on the bracket 1 by means of convex point riveting.

[0050] Further, a stop block 14 is installed at the bottom end of the fixed column 2. The stop block 14 in this embodiment is configured as a stop plastic buckle. A blind hole is opened at the top end of the stop block 14. After the buckle 3 and the adjusting member 4 are installed, the upper blind hole of the stop block 14 is correspondingly inserted into the bottom end of the fixed column 2, so that the stop block 14 is sleeved on the bottom end of the fixed column 2. At the same time, a stop hole 15 is opened on the side wall of the stop block 14, and a fixing hole is correspondingly provided on the bracket 1. The connecting member passes through the stop hole 15 and the fixing hole to realize the connection between the bottom end of the fixed column 2 and the bracket 1.

[0051] It should be noted that the stop hole 15 on the stop block 14 is configured as a screw hole or a pin hole, and the fixing hole on the bracket 1 is configured as a salad hole. The connecting member includes but is not limited to a countersunk head screw, a screw, a pin or a wood nail.

[0052] In a specific embodiment, in order to ensure that the product 5 to be fixed on the bracket 1 is located within the accommodating space and to improve the overall stability of the product 5 to be fixed, a limiting hole 502 is provided on the product 5 to be fixed, and two limiting holes 502 are symmetrically provided at both ends of the product 5 to be fixed. A limiting member 16 corresponding to the limiting hole 502 is provided on the bracket 1. In this embodiment, the limiting member 16 is an I-shaped nail, and two I-shaped nails are symmetrically provided on the side wall of the bracket 1, respectively corresponding to the limiting holes 502 on the product 5 to be fixed. The limiting holes 502 are adjusted to be installed correspondingly on the limiting member 16 so that the product 5 to be fixed is placed within the accommodating space.

[0053] like Figure 6 , Figure 7 and Figure 8 As shown, since several expansion cards usually need to be installed on the side wall of the bracket 1 to provide more slots for the PCIE board, that is, it is necessary to install multiple layers of expansion cards in the height direction of the side wall of the bracket 1, further, the limiting hole 502 is set as a gourd-shaped hole or a strip hole, and a slide is set on the bracket 1, that is, each layer of expansion card corresponds to a slide, the slide is L-shaped, and the L-shaped slide support is connected to the bottom side wall of the product 5 to be fixed, and the slide is set at the lower part of the limiting member 16. When it is necessary to insert the limiting hole 502 on the product 5 to be fixed into the limiting member 16 on the bracket 1, the bottom side wall of the product 5 to be fixed is adjusted to fit with the slide, and the product 5 to be fixed is adjusted to slide in the direction close to the fixing column 2, so that the product 5 to be fixed moves into the accommodating space, and finally the positioning block 7 on the buckle 3 is driven by the adjusting member 4 to be inserted into the positioning hole 501 to realize the positioning of the product 5 to be fixed.

[0054] It should be noted that in this embodiment, a first label is set on the driving sheet 302 and a second label is set on the adjusting sheet 601 , wherein the content of the second label is set to “ALL” to indicate that multiple latches 3 can be unlocked and fixed simultaneously through the adjusting sheet 601 .

[0055] Specific implementation process: confirm the corresponding number of fasteners 3 according to the number of products 5 to be fixed, match the first curling edge 3011 hole of the fastener 3 with the bottom end of the fixing column 2, place the elastic member 8 between the two first curling edges 3011, and align the middle hole of the elastic member 8 with the first curling edge 3011 hole, adjust the fastener 3 from the bottom end of the fixing column 2 to pass through the fixing column 2, when the first curling edge 3011 is engaged with the first protrusion 10 on the fixing column 2, at this time, the fastener 3 is passed to the preset position, adjust the first support rod 801 of the elastic member 8 to be connected to the baffle body 301, adjust the second support rod 802 of the elastic member 8 to correspond to the card slot 9 to complete the installation of a fastener 3, and similarly, The fastener 3 is passed through the fixing column 2; the second curling hole 403 in the adjusting member 4 is matched with the fixing column 2, and the adjusting member 4 is passed through the fixing column 2 along the bottom of the fixing column 2, and the adjusting end 6 is adjusted to slide along the fixing column 2 until the second curling hole 403 is engaged with the second protrusion 11. At this time, the adjusting member 4 is passed through the preset position to ensure that the adjusting end 6 is located closer to the side of the product 5 to be fixed than the movable end of the fastener 3; after the fastener 3 and the adjusting member 4 are installed, the top end of the fixing column 2 is installed on the bracket 1, and the stop block 14 is installed at the bottom end of the fixing column 2, and the stop hole 15 on the stop block 14 is adjusted to correspond to the fixing hole on the bracket 1, and the connecting member passes through the stop hole 15 and the fixing hole to realize the connection between the bottom end of the fixing column 2 and the bracket 1.

[0056] Then, according to the corresponding directions of the limiting hole 502 on the product 5 to be fixed and the limiting member 16, the product 5 to be fixed is inserted into the side wall of the bracket 1.
