[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] like Figure 1-5 As shown, a computer motherboard fixing device for a computer comprises a heat conducting plate 1 for placing the motherboard and a pressing block 3 for clamping the corner of the motherboard, a plurality of slide grooves 2 are provided on the heat conducting plate 1, a slider 9 for installing the pressing block 3 is slidably connected in the slide groove 2, a spring rod 7 parallel to and plugged in the slide groove 2 is fixedly connected to the bottom of one side of the slider 9, a secondary traction rope 11 is fixedly connected to the middle part of one side of the slider 9, one end of the secondary traction rope 11 passes through the slide groove 2 away from the center side of the heat conducting plate 1, and a rotating block 4 is rotatably connected to the center of one side of the heat conducting plate 1, two main traction ropes 5 are wound around the rotating block 4, the plurality of secondary traction ropes 11 are equally divided into two groups and symmetrically distributed, the two main traction ropes 5 correspond to the two groups of secondary traction ropes 11, and the main traction rope 5 is connected to the plurality of secondary traction ropes 11.

[0025] In this plan:

[0026] The main traction rope 5 is rotated and wound by the rotating block 4, and the main traction rope 5 drives the auxiliary traction rope 11 to move, and then the slider 9 is driven to move by the auxiliary traction rope 11. When the spring rod 7 is in a fixed position, the spring rod 7 is compressed during the movement of the slider 9, that is, a plurality of sliders 9 and the pressing block 3 are simultaneously moved away from the center of the heat conducting plate 1. After the main board is placed between the plurality of sliders 9 on the heat conducting plate 1, the rotating block 4 is released, and the spring rod 7 elastically stretches and resets, thereby pushing the slider 9 and the pressing block 3 to move until the pressing block 3 is close to the corner of the main board, and the elastic pushing effect of the spring rod 7 on the slider 9 is used to achieve the compression of the main board.

[0027] like Figure 1As shown: the edge of the rotating block 4 is an annular hollow setting, and the rotating block 4 and the side of the heat conducting plate 1 are positioned by a pin shaft.

[0028] In this plan:

[0029] The hollowing out of the edge allows the main traction rope 5 to be wrapped around the rotating block 4. After the slider 9 is moved, before the main board is placed in, the position of the slider 9 can be initially fixed by passing the pin shaft through the rotating block 4 and the side of the heat conducting plate 1, ensuring that the main board can be smoothly placed between several pressing blocks 3.

[0030] like Figure 5 As shown, the pressing block 3 is clamped on the sliding block 9, and a spring 12 with one end connected to the pressing block 3 is embedded and fixedly connected on the sliding block 9.

[0031] The pressing block 3 has two columnar protrusions integrally formed on one side facing the center of the heat transfer plate 1 .

[0032] In this plan:

[0033] The spring 12 ensures that the pressing block 3 can move relative to the slider 9, that is, the distance between the pressing block 3 and the surface of the heat conducting plate 1 can be adjusted, which is convenient for personnel to put in motherboards of different thicknesses and hold the motherboards.

[0034] like Figure 3 and Figure 4 As shown: the spring rod 7 is fixedly connected to the cylinder body with a mounting seat 6, the bottom surface of the heat conducting plate 1 is located at the position of the slide groove 2 and is symmetrically fixedly connected with two guide rails 10, and the guide rails 10 are slidably connected to the side of the mounting seat 6.

[0035] The guide rail 10 is L-shaped, and an insert block 8 is inserted between the side wall of the guide rail 10 and the mounting seat 6. The side of the guide rail 10 is hollowed out to be inserted into the insert block 8, and the side of the mounting seat 6 is provided with a plurality of insertion holes 13 to be inserted into the insert block 8.

[0036] A bolt 14 is threadedly connected between the insert block 8 and the surface of the mounting seat 6 .

[0037] In this plan:

[0038] By removing the bolt 14, the plug block 8 can be pulled out, so that the mounting seat 6 can slide along the surface of the guide rail 10, and the initial distance between the spring rod 7, the slider 9 and the pressure block 3 and the center of the heat conducting plate 1 can be adjusted, so as to facilitate the clamping of motherboards of different sizes. Then, the guide rail 10 and the mounting seat 6 are passed through the plug block 8 again, and the bolt 14 is passed through the plug block 8 and the mounting seat 6, so that the relative position of the mounting seat 6 and the guide rail 10 can be fixed, and the initial position of the slider 9 and the pressure block 3 can be adjusted. After the adjustment, the auxiliary traction rope 11 on the slider 9 is in a relaxed state, and the relaxed main traction rope 5 and auxiliary traction rope 11 can be tightened and straightened by rotating the rotating block 4.

[0039] Working principle: before installing the mainboard, rotate the rotating block 4, wrap the main traction rope 5, and drive the auxiliary traction rope 11 to move through the main traction rope 5, so that the slider 9 can overcome the elastic force of the spring rod 7 and move away from the center of the heat conducting plate 1. After moving a certain distance, place the mainboard on the heat conducting plate 1, and the corner corresponds to the pressure block 3. Release the rotating block 4, and the spring rod 7 elastically resets to push the slider 9 and the pressure block 3 to move toward the center of the heat conducting plate 1 until the pressure block 3 is against the corner of the mainboard.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
