One end of the limit block 11 slides into the installation groove 13 to connect the disc spring 14. The top surface of the limit block 11 away from the end of the vertical plate 8 is provided with a wedge surface 15. Considering that the size of the plug-in column 10 is small, the installation space of the installation groove 13 is limited. The disc spring 14 is used to connect the limit block 11 and the plug-in column 10, so that the limit block 11 can be reset in a small range. The plug-in column 10 is axially penetrated with a center hole 16. The bottom of the installation groove 13 is provided with a wedge surface 15. A small hole 17 connected to the center hole 16 is opened at the top, and each plug-in column 10 is correspondingly provided with a pull ring 18. The vertical plate 11 is located between the pull ring 18 and the plug-in column 10. The limit block 11 is connected to a pull wire 19, and the pull wire 19 passes through the inner hole of the disc spring 14, the small hole 17 and the center hole 16 to connect the pull wire 19; when the front air guide cover 1 is connected to the combined air guide cover 2, the plug-in column 10 is inserted into the limit ring 12. During the insertion of the plug-in column 10, the wedge surface 15 of the limit block 11 contacts the limit ring 12. Under the action of the wedge surface 15, the limit The positioning block 11 squeezes the disc spring 14 to move into the installation groove 13. When the limiting block 11 is completely moved into the installation groove 13, the plug-in column 10 can be smoothly plugged into place, so that the vertical plate 8 contacts the front air guide cover 1.

The positioning cone 20 is adapted in the positioning hole 21. The movement of the combined air guide cover 2 is guided by the cooperation between the positioning cone 20 and the positioning hole 21, so that the combined air guide cover 2 can be quickly and accurately connected to the front air guide cover 1.

[0034] Embodiment 3

[0035] On the basis of implementation 2, Figure 8 and Fig. 9As shown, it also includes a windshield 22. The windshield 22 and the combined wind guide cover 2 are individually installed on the front wind guide cover 2. A windshield plug-in column 23 is arranged on the windshield 2. The structure of the windshield plug-in column 23 is the same as the structure of the plug-in column 10. The windshield 22 is connected to the front wind guide cover 2 through the cooperation of the windshield plug-in column 23 and the limit ring 12. The windshield 22 is used to close one end of the first air guide groove 6. When the GPU card is not installed, the combined wind guide cover 2 is removed, and the windshield 22 is installed at the end of the front wind guide cover 2. The connection between the windshield 22 and the front wind guide cover 2 is completed through the cooperation of the windshield plug-in column 23 and the limit ring 12. The end of the first air guide groove 6 is closed by the windshield 22, so that the air hits the windshield 22 and then flows back, thereby reducing the amount of air flowing into the rear of the front wind guide cover 2, thereby improving the heat dissipation effect.

[0036] Embodiment 4

[0037] Based on the third embodiment, Figure 1 and Figure 7As shown, a horizontal mounting groove 24 is provided on one side of the horizontal sinking plate 9, and a plurality of through holes 25 are provided on the top of the horizontal sinking plate 9. The through holes 25 are connected to the horizontal mounting groove 24, and the diameter of the through holes 25 gradually decreases in the direction close to the horizontal mounting groove 24. A locking bead 26 is movably provided in the through hole 25, and the diameter of the locking bead 26 is larger than the minimum diameter of the through hole 25. One end of the GPU card bearing plate 3 is slidably adapted in the horizontal mounting groove 24, and a groove 27 is provided on the top surface of the GPU card bearing plate 3 at a position corresponding to the through hole 25. A sliding lock plate 28 is slidably provided on the top surface of the horizontal sinking plate 9, and an unlocking groove 29 is provided on the bottom surface of the sliding lock plate 28 at a position corresponding to the through hole 25. When the unlocking groove 29 is unlocked, When the locking bead 26 is arranged alternately with the through hole 29 and the through hole 25, the locking bead 26 is partially adapted in the groove 27, and the bottom plane of the sliding lock plate 28 contacts the locking bead 26; when the locking bead 26 contacts the inner top wall of the unlocking groove 29, the locking bead 26 is disengaged from the groove 27; to avoid interference, the GPU card will be installed first, then the combined air duct cover 2 will be installed, and finally the GPU card load-bearing plate 3 will be installed. Since the GPU card load-bearing plate 3 is not installed, there is enough space in the server to install the combined air duct cover 2. Therefore, the combined air duct cover 2 is connected to the front air duct cover 1 in a plug-in manner to achieve quick connection. At this time, the installation space left for the GPU card load-bearing plate 3 is small. In order to facilitate the installation of the GPU card load-bearing plate 3 The GPU card load-bearing plate 3 is installed by using the space on both sides of the GPU card, that is, the GPU card load-bearing plate 3 slides into the horizontal installation groove 24 from one side of the horizontal sinking plate 9, so that the GPU card load-bearing plate 3 can be installed in a small space without colliding with the GPU card. During installation, the sliding lock plate 28 is moved to make the unlocking groove 29 correspond to the through hole 25. The tapered structure of the through hole 25 facilitates the placement of the locking bead 26 in the through hole 25, and the locking bead 26 will not pass through the bottom of the through hole 25. Under the gravity of the locking bead 26, a part of the locking bead 26 extends out of the through hole 25. In the process of the GPU card load-bearing plate 3 sliding into the horizontal installation groove 24, the GPU card load-bearing plate 3 The plate 3 will squeeze the locking bead 26, thereby pushing the locking bead 26 to move toward the unlocking groove 29, so that one end of the GPU card bearing plate 3 can slide smoothly into the horizontal installation groove 24. At this time, the unlocking bead 26 moves under the action of gravity, so that the locking bead 26 is partially adapted in the groove 27, and finally the sliding lock plate 28 is moved to make the bottom surface of the sliding lock plate 28 contact the locking bead 26, that is, the unlocking groove 29 and the through hole 25 are arranged alternately, so that the sliding lock plate 28 restricts the movement of the locking bead 26, so that the GPU card bearing plate 3 and the combined air guide cover 2 are stably connected together. To install the GPU card bearing plate 3, you only need to slide in the GPU card bearing plate 3 and move the sliding lock plate 28, which is simple to operate;When removing the GPU card bearing plate 3, first move the sliding lock plate 28 so that the unlocking groove 29 of the sliding lock plate 28 corresponds to the through hole 25, and then slide out the GPU card bearing plate 3. It should be noted that the cross-sectional shape of the groove 27 is rectangular and cannot lock the locking bead 26. During the movement of the GPU card bearing plate 3, the locking bead 26 is squeezed and moved toward the unlocking groove 29, so that the GPU card bearing plate 3 can be smoothly removed from the combined air guide cover 2. Similarly, only two sliding actions are required to complete the disassembly, which is simple and quick to operate. ;

[0038] Furthermore, two mounting blocks 30 are fixed at intervals on the top of the horizontal sinking plate 9 along the sliding direction of the sliding lock plate 28. An elastic sleeve 31 is fixed on the sliding lock plate 28. A mounting hole is opened through the mounting block 30 along the moving direction of the sliding lock plate 28. The sliding lock plate 28 is slidably adapted to the mounting hole, and the elastic sleeve 31 is interference fit in the mounting hole through its own deformation. The interference fit of the elastic sleeve 31 makes a large friction force between the sliding lock plate 28 and the mounting block 30. The position of the sliding lock plate 28 is locked by this friction force, ensuring that the sliding lock plate 28 will not move accidentally during use, ensuring that the connection between the GPU card load-bearing plate 3 and the combined air guide cover 2 is stable, thereby continuously maintaining a good support effect on the GPU card.
