[0001] The utility model relates to the technical field of computer installation, in particular to a computer mainboard fixing structure. Background Art

[0002] The motherboard is the core of the computer hardware system and is also the largest printed circuit board in the main chassis. During the installation process of existing computer motherboards, screws are passed through the screw holes of the carrier plate to fasten to the inner wall of the chassis. The screw hole installation method requires the use of tools such as screwdrivers, but since the screwdriver has a certain length, the structure in the chassis will limit the rotation of the screwdriver, resulting in low installation efficiency of the motherboard.

[0003] To solve the above problems, a Chinese patent discloses a mechanical fixing structure for a computer carrier board (Announcement No.: CN213957991U). The public document sets a rotating shaft and a ratchet. The operator pushes the pawl to the right to disengage the ratchet, and then rotates the rotating shaft to drive the pull plate and the connecting plate to move downward. The first spring is compressed, and the sliding block slides in the inner cavity of the slide rail, while causing one end of the support column to tilt up, so that the operator can place the mainboard on the support column and then rotate the rotating shaft in the opposite direction to fix the mainboard on the top plate of the support column.

[0004] In view of the above problems, existing patents have provided solutions, but the sizes of motherboards are different, and different motherboards have different sizes of supporting columns that match them. When installing the motherboard, only a chassis that is compatible with the specifications of the motherboard can be selected, and the adaptability is low. In addition, when the motherboard is transported or shaken, it is easy to damage the computer motherboard, making the computer unusable. Summary of the invention

[0005] The purpose of the utility model is to provide a computer motherboard fixing structure, which can solve the problem that when the motherboard is installed, the holes of the motherboard need to be aligned with the holes of the chassis, most chassis of fixed models can only install motherboards of fixed models, and the motherboard will become loose when used for a long time, affecting the use of the computer.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a computer motherboard fixing structure, comprising a carrier plate, a mounting plate is provided at the bottom of the carrier plate, a plurality of mounting grooves are provided at the top of the mounting plate, connecting plates are fixedly connected to the four corners of the bottom of the carrier plate, and each two groups of connecting plates are symmetrically arranged, a rotating wheel is rotatably connected to the inner cavity of the connecting plate, a rotating rod is fixedly connected to the circumferential outer surface of the rotating wheel, a fixing block is fixedly connected to the other side of the rotating rod, a threaded hole is provided in the inner cavity of the fixing block, and a bolt is tightly set on the top of the mounting plate through the threaded hole.

[0007] Preferably, a plurality of ratchets are equidistantly and fixedly connected to the outer surface of the rotating wheel, the outer edges of the ratchets are in contact with a baffle, and the baffle is slidably connected to the bottom of the inner cavity of the connecting plate.

[0008] Preferably, the top of the baffle is fixedly connected to a limit spring, and the top of the limit spring is fixedly connected to the inner cavity of the connecting plate.

[0009] Preferably, an adjusting rod is slidably connected to the inner cavity of the rotating rod, and an end of the adjusting rod away from the connecting plate is fixedly connected to a fixing block.

[0010] Preferably, the left and right sides of the fixed block are respectively provided with latching grooves, and the inner cavity of the mounting plate is equidistantly and slidably connected with a plurality of movable plates.

[0011] Preferably, one end of the movable plate away from the mounting groove is fixedly connected to a sliding spring, and the other end of the sliding spring is fixedly connected to the inner cavity of the mounting plate.

[0012] Preferably, the other end of the movable plate is fixedly connected to a pulling plate, and the end of the movable plate away from the sliding spring is in an arc shape.

[0013] Preferably, a plurality of sliding grooves are equidistantly formed on the top of the mounting plate, and the pull plate is slidably connected to the top of the sliding grooves.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The present application sets a rotating wheel, and the operator moves the adjusting rod upward, and the adjusting rod drives the rotating rod and the fixed block to rotate synchronously. The rotating rod drives the rotating wheel to rotate in the inner cavity of the connecting plate, and the rotating wheel drives the ratchet to rotate clockwise. The ratchet at the top of the baffle drives the baffle to move downward synchronously, so that the baffle gradually stretches the limit spring until the ratchet disengages from the top of the baffle. The baffle is driven upward by the force generated by the reset of the limit spring and re-contacts another ratchet, so that the operator can adjust the length of the adjusting rod and the fixed block by rotating the adjusting rod, which is convenient for the operator to fix the motherboard in the inner cavity of the chassis with different specifications, thereby improving the convenience during installation.

[0016] 2. The present application sets up a mounting groove. When the operator places the fixed block on the top of the mounting groove, the fixed block gradually squeezes the arc-shaped end face of the movable plate, so that the movable plate slides in the inner cavity of the mounting plate and gradually squeezes the sliding spring until the positioning groove on one side of the fixed block corresponds to one end of the movable plate. The compressed sliding spring pushes the movable plate into the positioning groove, fixes the fixed block on the top of the mounting plate, and preliminarily fixes the bearing plate on the top of the mounting plate, thereby preventing the bearing plate from sliding or shifting when installing the bolts, thereby improving the installation efficiency.

[0028] By adopting the above technical solution, when the operator wants to install the mainboard, after fixing the mainboard to the top of the bearing plate 1 with screws, the operator moves the adjusting rod 5 upwards, and the adjusting rod 5 drives the rotating rod 4 and the fixing block 13 to rotate synchronously, and the rotating rod 4 drives the rotating wheel 3 to rotate in the inner cavity of the connecting plate 2, and the rotating wheel 3 drives the ratchet 8 to rotate clockwise, and the ratchet 8 at the top of the baffle 9 drives the baffle 9 to move downward synchronously, so that the baffle 9 gradually stretches the limit spring 10 until the ratchet 8 breaks away from the top of the baffle 9, and the baffle 9 is driven upward by the force generated by the reset of the limit spring 10, and re-contacts with another ratchet 8, and the ratchet 8 at the bottom of the baffle 9 wants to reverse. When the hour hand rotates, it will be blocked by the baffle plate 9 to prevent the rotating wheel 3 and the rotating rod 4 from moving, thereby avoiding displacement of the supporting plate 1 and affecting the use of the computer. The operator can pull the adjusting rod 5 to make the adjusting rod 5 slide in the inner cavity of the rotating rod 4, thereby extending the position of the fixing block 13. After the positions of the fixing block 13 and the adjusting rod 5 are adjusted, the operator can place the fixing block 13 on the top of the mounting groove 6 and tighten the bolts on the top of the mounting plate 7 through the threaded holes 12 to complete the fixation of the supporting plate 1. The utility model enables the operator to install the motherboard in the inner cavity of the chassis of different specifications, thereby improving the adaptability of the motherboard installation.

[0029] Specifically, Figure 1 As shown, the left and right sides of the fixed block 13 are respectively provided with locking grooves 11, the inner cavity of the mounting plate 7 is equidistantly slidably connected with a plurality of movable plates 14, the end of the movable plate 14 away from the mounting groove 6 is fixedly connected with a sliding spring 15, the other end of the sliding spring 15 is fixedly connected to the inner cavity of the mounting plate 7, the other end of the movable plate 14 is fixedly connected with a pulling plate 16, the end of the movable plate 14 away from the sliding spring 15 is in an arc shape, and a plurality of sliding grooves 17 are equidistantly provided on the top of the mounting plate 7, and the pulling plate 16 is slidably connected to the top of the sliding groove 17.

[0030] By adopting the above technical scheme, when the operator places the fixed block 13 on the top of the mounting groove 6, the fixed block 13 gradually squeezes the arc-shaped end face of the movable plate 14, so that the movable plate 14 slides in the inner cavity of the mounting plate 7 and gradually squeezes the sliding spring 15 until the locking groove 11 on one side of the fixed block 13 corresponds to one end of the movable plate 14, and the compressed sliding spring 15 of the movable plate 14 pushes the locking groove 11 to preliminarily fix the fixed block 13 on the top of the mounting plate 7 to prevent the bearing plate 1 from sliding or shifting when installing the bolts.

After the positions of the fixed block 13 and the adjusting rod 5 are adjusted, the operator can place the fixed block 13 on the top of the mounting groove 6. The fixed block 13 gradually squeezes the arc-shaped end face of the movable plate 14, so that the movable plate 14 slides in the inner cavity of the mounting plate 7 and gradually squeezes the sliding spring 15 until the positioning groove 11 on one side of the fixed block 13 corresponds to one end of the movable plate 14. The compressed sliding spring 15 of the movable plate 14 pushes the card into the positioning groove 11, and the fixed block 13 is initially fixed to the top of the mounting plate 7.
