Description

Technical Field

[0001] This utility model relates to the field of computer technology, and in particular to a computer motherboard fixing device. Background Technology

[0002] The motherboard, also called the mainboard, system board, or motherboard, is one of the most basic and important components of a computer. The motherboard is generally a rectangular circuit board on which the main circuitry of the computer is installed. The motherboard plays an important role in the use of a computer, so it needs to be installed inside the computer to ensure its normal operation.

[0003] For computer motherboards, they are usually fixed directly to the chassis wall with bolts. However, in this process, the motherboard is in close contact with the chassis wall, which is not conducive to heat dissipation and is not convenient for subsequent disassembly and maintenance. Existing computer motherboard fixing devices cannot effectively fix computer motherboards of different specifications, thus reducing the cost of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a computer motherboard fixing device that can limit and fix the motherboard according to different motherboard sizes, improve the adaptability of the device, and facilitate the subsequent disassembly and maintenance of the motherboard.

[0005] To achieve the above objectives, a computer motherboard fixing device is provided, including a chassis. A knob is rotatably connected to the front outer surface of the chassis, and a rotating shaft is fixedly connected to the rear outer surface of the knob. A first screw is fixedly connected to the rear end of the rotating shaft, and the rear end of the first screw is rotatably connected to the rear inner surface of the chassis. A bidirectional threaded rod one and a bidirectional threaded rod two are provided on the upper part of the first screw. Two threaded blocks are threadedly connected to the outer surfaces of both the bidirectional threaded rod one and the bidirectional threaded rod two. A positioning plate is provided on the right side of the threaded blocks. By adjusting the positioning plate, the motherboard of different specifications can be limited and fixed, thereby improving the adaptability of the device.

[0006] The positioning plate has a positioning block one and a positioning block two inside. A second screw is threaded through the outer right surface of the positioning plate. The left end of the second screw is rotatably connected to the outer right surface of the positioning block one. A rotating block is fixedly connected to the right end of the second screw. The positioning blocks one and two further fix the computer motherboard and facilitate subsequent disassembly and maintenance.

[0007] According to the aforementioned computer motherboard fixing device, a first bevel gear is fixedly connected to the front outer surface of the first screw, and a second bevel gear is meshed with the upper outer surface of the first bevel gear. The second bevel gear is fixedly connected to the outer surface of the bidirectional threaded rod, thereby realizing the connection between the first screw and the bidirectional threaded rod.

[0008] According to the aforementioned computer motherboard fixing device, a third bevel gear is fixedly connected to the rear outer surface of the first screw, and a fourth bevel gear is meshed with the upper outer surface of the third bevel gear. The fourth bevel gear is fixedly connected to the outer surface of the second bidirectional threaded rod, thereby realizing the connection between the first screw and the second bidirectional threaded rod.

[0009] According to the aforementioned computer motherboard fixing device, a fixing block is fixedly connected to the right outer surface of the threaded block, a moving block is fixedly connected to the right outer surface of the fixing block, and a moving groove is provided on the left inner surface of the chassis, with the moving block moving inside the moving groove.

[0010] According to the aforementioned computer motherboard fixing device, a limiting post is provided on the right side of the positioning plate. The limiting post slides through the outer right surface of the positioning plate and is fixedly connected to the outer left surface of the positioning block, thereby limiting the positioning block.

[0011] According to the aforementioned computer motherboard fixing device, a positioning post is fixedly connected to the outer left surface of the second positioning block, and a buffer spring is provided on the outer surface of the positioning post to position the motherboard.

[0012] According to the aforementioned computer motherboard fixing device, the upper outer surface of the positioning plate is provided with several slots, and a cooling fan is installed inside the slot to dissipate heat from the motherboard, thereby preventing the motherboard from overheating during prolonged use and affecting the operation of the computer.

[0013] According to the aforementioned computer motherboard fixing device, a buffer pad is fixedly connected to the right outer surface of the positioning block one and the left outer surface of the positioning block two. The buffer pad is made of heat dissipation material and serves a protective function.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with the prior art, this computer motherboard fixing device, by rotating a knob, drives the rotating shaft to rotate, and then through the arrangement of the first bevel gear, the second bevel gear, the third bevel gear and the fourth bevel gear, respectively drive the double-threaded rod one and the double-threaded rod two to rotate, thereby driving the threaded block, the fixing block and the moving block to move. This allows the positioning plate to be adjusted according to the size of different computer motherboards, thereby limiting and fixing the computer motherboard. Then, by rotating the rotating block, the second screw and the positioning block one are driven to move to the left, and the upper and lower ends of the computer motherboard are fixed by the action of the positioning block two, the positioning post and the buffer spring. This improves the applicability of the device, and at the same time, the cooling fan dissipates heat and extends its service life.

[0016] 2. Compared with the prior art, this computer motherboard fixing device, by rotating the rotating block in the opposite direction, drives the second screw to move to the right, so that the computer motherboard is freed from the fixing of positioning block one and positioning block two. Then, by rotating the knob, the two positioning plates are moved away from the computer motherboard, thereby removing the computer motherboard and completing the disassembly of the computer motherboard. It is simple and convenient.

Then, the knob 2 is rotated to move the two positioning plates 14 away from the computer motherboard, thereby removing the computer motherboard and completing its disassembly. It is simple and convenient.
