[0029] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0030] See Figures 1 to 11As shown, a quick-release structure for a graphics card includes a locking screw 1 and a sliding locking block 2. The locking screw 1 is installed on the chassis A and has a locking groove 11 that engages with the sliding locking block 2. The sliding locking block 2 is slidably installed on the graphics card B and has a C-shaped slot 20 that engages with the locking groove 11. By installing the sliding locking block 2 on the graphics card B and installing the locking screw 1 on the chassis A, the C-shaped slot 20 on the sliding locking block 2 slides and engages with the locking groove 11 on the locking screw 1 to fix the graphics card B to the chassis A. To remove the graphics card B, simply push the sliding locking block 2 to move the C-shaped slot 20 out of the locking groove 11, thus achieving quick installation and removal of the graphics card B.

[0031] The front mounting plate B1 of the graphics card B is provided with a first limiting part B11 for sliding and positioning the sliding locking block 2, and a first locking part B12 for fixing the sliding locking block 2. One end of the sliding locking block 2 is bent to form a vertical plate part 28 for easy movement. By providing the first locking part B12 on the front mounting plate B1 to fix the sliding locking block 2, when the sliding locking block 2 is pushed and engaged with the locking screw 1, the first locking part B12 fixes the sliding locking block 2, so that the graphics card B and the chassis A are stably installed and will not slide off. The lower end of the front mounting plate B1 still has a traditional insert for fastening with the chassis A. This insert is used to insert into the socket of chassis A to fix the lower end of the front mounting plate B1 to chassis A. Since the direction of the insert is consistent with the direction of the graphics card B on the motherboard, the connection between the lower end of the front mounting plate B1 and chassis A is achieved simultaneously with the disassembly and assembly of graphics card B and motherboard. When disassembling and assembling graphics card B, this invention only requires operating the sliding locking block 2 at the upper end of the front mounting plate B1. The operation is simple and efficient, and it can achieve quick disassembly and assembly of graphics card B.

[0032] See Figures 3 to 5 As shown in Embodiment 1 of the present invention, the first limiting part B11 is an arched hole, and one end of the sliding locking block 2 passes through the first limiting part B11; the first locking part B12 is a protrusion located beside the first limiting part B11, and the sliding locking block 2 is provided with at least two spaced first positioning holes 21 that can engage with the protrusion. By providing an arched hole-shaped first limiting part B11 on the front mounting plate B1 of the graphics card B, the sliding locking block 2 is slidably limited after passing through the first limiting part B11. The first locking part B12 with the protrusion matches the first locking hole 21, thereby fixing the sliding locking block 2 in two positions. When the C-shaped slot 20 of the sliding locking block 2 is slidably inserted into the locking slot 11 of the locking screw 1, the relative locking and fixing of the chassis A and the graphics card B is achieved by the sliding locking block 2.

[0033] See Figures 6 to 8As shown in Embodiment 2 of the present invention, the front mounting plate B1 is further provided with a first locking screw B2 for cooperating with the first limiting part B11 to limit the sliding locking block 2. The first locking screw B2 and the first limiting part B11 are respectively located on both sides of the locking screw 1. The sliding locking block 2 is provided with a first travel hole 22 and a second travel hole 23 corresponding to the locking screw 1 and the first locking screw B2, respectively. The C-shaped groove 20 is located on one side of the first travel hole 22, and one end of the sliding locking block 2 is also provided with a protrusion 24 extending into the first limiting part B11. Based on Embodiment 1, this embodiment limits the sliding locking block 2 by adding a first locking screw B2 to the front mounting plate B1. The first limiting part B11 and the first locking screw B2 are set on both sides of the locking screw 1, and a first travel hole 22 is provided on the sliding locking block 2 for the locking screw 1 to pass through. By pushing the sliding locking block 2 to move, the C-shaped groove 20 on one side of the first travel hole 22 is engaged into the locking groove 11 of the locking screw 1, realizing the locking connection between the sliding locking block 2 and the locking screw 1. The first limiting part B11 and the first locking screw B2 located on both sides of the locking screw 1 can maintain the rigidity of both ends of the sliding locking block 2, and prevent the sliding locking block 2 from deforming under force during use, which would cause the C-shaped groove 20 to disengage from the locking groove 11, further improving the stability of the structure.

[0034] The second travel hole 23 is strip-shaped to allow the sliding lock block 2 to slide. The first locking screw B2 is fitted with a first washer B21 that contacts the sliding lock block 2. The first limiting part B11 is an arched hole for the protruding part 24 to be inserted. The first locking part B12 is a protrusion located next to the first locking screw B2. The sliding lock block 2 is provided with at least two spaced first positioning holes 21 that can lock with the protrusion.

[0035] See Figures 9 to 11 As shown in Embodiment 3 of the present invention, the front mounting plate B1 of the graphics card B is provided with a second locking screw B3 and a third locking screw B4 for sliding positioning of the sliding locking block 2, and a first locking part B12 for positioning and fixing the sliding locking block 2. The sliding locking block 2 is provided with a third stroke hole 25, a fourth stroke hole 26, and a fifth stroke hole 27 corresponding to the locking screw 1, the second locking screw B3, and the third locking screw B4, respectively. The C-shaped slot 20 is located on one side of the fourth stroke hole 26. This embodiment is based on Embodiment 2, replacing the first limiting part B11 with the second locking screw B3. The sliding locking block 2 is limited and fixed by the second locking screw B3 and the third locking screw B4, thereby further improving the overall structural strength.

[0036] The third travel hole 25 and the fifth travel hole 27 are strip-shaped to allow the sliding locking block 2 to slide. The second locking screw B3 and the third locking screw B4 are each fitted with a second washer that contacts the sliding locking block 2. The first locking part B12 is a protrusion located beside the third locking screw B4. The sliding locking block 2 is provided with at least two spaced-apart first positioning holes 21 that can engage with the protrusion.

[0037] In summary, in this invention, by first fixing the locking screw 1 to the chassis A, and then fixing the sliding locking block 2 to the front mounting plate B1 of the graphics card B through the first limiting part B11 and / or the first locking screw B2, or by fixing the sliding locking block 2 to the front mounting plate B1 of the graphics card B through the second locking screw B3 and the third locking screw B4, when the graphics card B is inserted into the motherboard, the lower end of the front mounting plate B1 will automatically connect with the socket of chassis A, and at this time the locking screw 1 will be on one side of the C-shaped slot 20. By moving the sliding locking block 2, the C-shaped slot 20 is engaged into the locking slot 11, thereby achieving the engagement of the sliding locking block 2 and the locking screw 1, thus connecting the upper end of the front mounting plate B1 of the graphics card B to the chassis A, completing the installation and fixing of the graphics card B to the chassis A. When it is necessary to remove the graphics card B, the C-shaped slot 20 is disengaged from the slot 11 by moving the sliding locking block 2, so that the sliding locking block 2 is separated from the slot screw 1, thereby allowing the graphics card B to be directly pulled out from the motherboard without the need for tools such as screwdrivers to insert or remove the graphics card B.
