An adjustment block is threadedly sleeved onto the surface of the threaded rod.

[0009] Preferably, the connecting plates are in two sets, and the surface of the connecting plates is provided with rotating grooves. The limiting rotating shaft is rotatably connected to the inside of the connecting plate through the clamping handle, and the cam is rotatably connected to the inside of the connecting plate through the limiting rotating shaft.

[0010] Preferably, the connecting shafts are symmetrically distributed in two groups on the surface of the first clamping plate, the connecting shafts are symmetrically distributed in two groups on the surface of the second clamping plate, the damping springs are symmetrically distributed in two groups on the surface of the connecting shafts, and the two ends of the damping springs are sleeved on the surfaces of the two sets of connecting shafts.

[0011] Preferably, the surface of the connecting plate is provided with a movable groove, and the guide rods are symmetrically distributed in two groups on the surface of the connecting plate. The first clamping plate is connected to the surface of the cam by a damping spring, and the second clamping plate is connected to the surface of the cam by a damping spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

By connecting the first clamping plate and the graphics card, the graphics card is placed between the first and second clamping plates. Then, by connecting the clamping handle and the limiting shaft, and the connecting shaft and the damping spring, rotating the clamping handle again causes the cam to leave the surfaces of the first and second clamping plates. The damping spring returns to its original shape, causing the first and second clamping plates to clamp and fix the position of the graphics card, thus achieving the effect of facilitating the limiting of the graphics card.

[0017] 2. By adjusting the connection between the throttle and the worm gear, and the connection between the worm gear and the connecting rod, the throttle rotation causes the worm gear and the connecting rod to rotate accordingly. Then, through the connection between the fixed shaft and the worm wheel, and the connection between the worm wheel and the threaded rod, the rotation of the worm gear drives the worm wheel and the threaded rod to rotate on the surface of the fixed shaft. Finally, through the connection between the threaded rod and the adjusting block, and the connection between the adjusting block and the connecting plate, the rotation of the threaded rod causes the adjusting block and the connecting plate to rise and fall on the surface of the connecting frame, thus achieving the effect of adjusting the working height of the graphics card.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7One embodiment provided by this utility model:

[0028] A computer case that facilitates hardware positioning, comprising:

[0029] The enclosure includes a host chassis 1, which is used to protect the host hardware. The host chassis 1 contains a graphics card 11, which is used to improve the system's rendering and creation efficiency.

[0030] The limiting mechanism includes a connecting plate 2, which acts inside the main unit case 1 to connect a first clamping plate 24 and a second clamping plate 27. A clamping handle 21 is rotatably connected to the surface of the connecting plate 2 to drive a limiting shaft 22 to rotate. The limiting shaft 22 is fixedly connected to the surface of the clamping handle 21 to connect a cam 23. The cam 23 is fixedly connected to the surface of the limiting shaft 22 to control the working distance between the first clamping plate 24 and the second clamping plate 27 by its own rotation. The first clamping plate 24 is movably connected to the surface of the connecting plate 2 for placing the graphics card 11. A connecting shaft 25 is fixedly connected to the surface of the first clamping plate 24 to connect a damping spring 26. The damping spring 26 is sleeved on the surface of the connecting shaft 25 to drive the first clamping plate 24 and the second clamping plate 27 to clamp the graphics card 11. The second clamping plate 27 is movably connected to the surface of the connecting plate 2 to cooperate with the first clamping plate 24 to clamp and fix the graphics card 11. A guide rod 28 is fixedly connected to the surface of the connecting plate 2 to provide guidance for the movement of the first clamping plate 24 and the second clamping plate 27.

[0031] The adjustment mechanism includes a connecting frame 3, which is fixedly connected inside the main unit housing 1 and is used to adjust the working height of the connecting plate 2. An adjustment handle 31 is rotatably connected to the surface of the connecting frame 3 to drive the worm gear 32 to rotate. The worm gear 32 is fixedly connected to the surface of the adjustment handle 31 to drive the worm wheel 35 to rotate. A connecting rod 33 is fixedly connected to the end of the worm gear 32 away from the adjustment handle 31 to connect two sets of worm gears 32. A fixed shaft 34 is fixedly connected inside the connecting frame 3 to allow the worm wheel 35 to rotate. The worm gear 35 is meshed with the surface of the worm gear 32 to drive the threaded rod 36 to rotate. The threaded rod 36 is fixedly connected to the surface of the worm wheel 35 to raise and lower the adjusting block 37 by its own rotation. The adjusting block 37 is threadedly sleeved onto the surface of the threaded rod 36 to connect the connecting plate 2 to the surface of the threaded rod 36.

[0032] Furthermore, the connecting plate 2 is in two sets, used to connect the graphics card 11 from both sides. The surface of the connecting plate 2 is provided with a rotating groove for clamping the rotating handle 21 to rotate. The limiting rotating shaft 22 is rotatably connected to the inside of the connecting plate 2 through the clamping rotating handle 21. The cam 23 is rotatably connected to the inside of the connecting plate 2 through the limiting rotating shaft 22. Rotating the clamping rotating handle 21 can drive the limiting rotating shaft 22 and the cam 23 to rotate inside the connecting plate 2.

[0033] Furthermore, the connecting shafts 25 are symmetrically distributed in two groups on the surface of the first clamping plate 24, and in two groups on the surface of the second clamping plate 27. The damping springs 26 are symmetrically distributed in two groups on the surface of the connecting shafts 25. The two ends of the damping springs 26 are sleeved on the surfaces of the two groups of connecting shafts 25. The four groups of connecting shafts 25 are respectively distributed on the surfaces of the first clamping plate 24 and the second clamping plate 27, and then the two groups of damping springs 26 are connected to help the first clamping plate 24 and the second clamping plate 27 clamp and fix the position of the graphics card 11.

[0034] Furthermore, the surface of the connecting plate 2 is provided with a movable groove for the movement of the first clamping plate 24 and the second clamping plate 27. The guide rods 28 are symmetrically distributed in two sets on the surface of the connecting plate 2. The first clamping plate 24 is connected to the surface of the cam 23 by the damping spring 26 and the second clamping plate 27 by the damping spring 26 and the surface of the cam 23. The deformation of the damping spring 26 causes the first clamping plate 24 and the second clamping plate 27 to abut against the surface of the cam 23.

[0035] Furthermore, the first clamping plate 24 is movably connected to the surface of the connecting plate 2 via the cam 23, and the first clamping plate 24 is movably connected to the surface of the connecting plate 2 via the guide rod 28. The second clamping plate 27 is movably connected to the surface of the connecting plate 2 via the cam 23, and the second clamping plate 27 is movably connected to the surface of the connecting plate 2 via the guide rod 28. The graphics card 11 is abutted together by the surfaces of the first clamping plate 24 and the second clamping plate 27. The rotation of the cam 23 increases the distance between the first clamping plate 24 and the second clamping plate 27, thereby deforming the damping spring 26 and placing the graphics card 11 between the first clamping plate 24 and the second clamping plate 27. When the cam 23 is rotated again, the damping spring 26 returns to its original shape, causing the first clamping plate 24 and the second clamping plate 27 to reset and fix the position of the graphics card 11.

[0036] Furthermore, the connecting frame 3 is in two sets, which are used to connect the two sets of connecting plates 2. The worm 32 is rotatably connected to the inside of the connecting frame 3 through the adjusting handle 31. The two ends of the connecting rod 33 are fixedly connected to the surface of the two sets of worms 32. The worm wheel 35 is rotatably connected to the surface of the fixed shaft 34 through the worm 32. Rotating the adjusting handle 31 drives the worm 32 to rotate, so that the connecting rod 33 and the other set of worms 32 follow the rotation, thereby driving the two sets of worm wheels 35 to rotate on the surface of the fixed shaft 34.

[0037] Furthermore, the threaded rod 36 is rotatably connected to the surface of the connecting frame 3 via the worm gear 35, and the adjusting block 37 is fixedly connected to the surface of the connecting plate 2. The adjusting block 37 is movably connected to the surface of the connecting frame 3 via the threaded rod 36, and the connecting plate 2 is movably connected to the surface of the connecting plate 2 via the adjusting block 37. The rotation of the worm gear 35 drives the threaded rod 36 to rotate, thereby causing the adjusting block 37 to drive the connecting plate 2 to rise and fall on the surface of the connecting frame 3.

[0038] Working principle: When using the host case 1, the graphics card 11 needs to be installed. Rotating the clamping handle 21 drives the limiting shaft 22 and cam 23 to rotate. The rotation of cam 23 increases the distance between the first clamping plate 24 and the second clamping plate 27, thereby deforming the damping spring 26 and placing the graphics card 11 between the first clamping plate 24 and the second clamping plate 27. Rotating cam 23 again causes the damping spring 26 to return to its original shape, driving the first clamping plate 24 and the second clamping plate 27 to reset and fix the position of the graphics card 11, thus completing the installation of the graphics card 11. Then, the effective height of the graphics card 11 can be adjusted as needed. By rotating the adjusting handle 31, the worm gear 32 is rotated, causing the connecting rod 33 and another set of worm gears 32 to rotate, thereby driving the two sets of worm wheels 35 to rotate on the surface of the fixed shaft 34. The rotation of the worm wheels 35 drives the threaded rod 36 to rotate, thereby causing the adjusting block 37 to drive the connecting plate 2 to rise and fall on the surface of the connecting bracket 3, thus adjusting the effective height of the graphics card 11.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
