[0030] Working principle:
[0031] When the device is used, the first fixing seat 14 is convenient for fixing the first limiting block 4 and the first silica gel sheet 3 together, the second fixing seat 15 is convenient for fixing the second limiting block 8 and the second silica gel sheet 7 together, and the third fixing seat 16 is convenient for fixing the third limiting block 12 and the lower silica gel pad 11 together. The contact area of the upper silica gel pad 1 and the first silica gel sheet 3 is increased through the first limiting block 4, so that the friction between the upper silica gel pad 1 and the first silica gel sheet 3 is increased. The contact area of the first silica gel sheet 3 and the second silica gel sheet 7 is increased through the second limiting block 8, so that the friction between the first silica gel sheet 3 and the second silica gel sheet 7 is increased. The contact area between the second silica gel sheet 7 and the lower silica gel pad 11 is increased through the third limiting block 12, so that the friction between the second silica gel sheet 7 and the lower silica gel pad 11 is increased. Therefore, the upper silica gel pad 1, the first silica gel sheet 3, the second silica gel sheet 7 and the lower silica gel pad 11 are not easy to slide relative to each other when they are placed together, so that the stability of the upper silica gel pad 1, the first silica gel sheet 3, the second silica gel sheet 7 and the lower silica gel pad 11 when they are placed is improved. The heat-conducting pad piece is placed in the gap between the circuit board and the heat sink. When the heat-conducting pad piece is relatively thick, the upper silica gel pad 1 is moved to the left, so that the first limiting block 4 is separated from the first limiting groove 2. The first silica gel sheet 3 is moved to the left, so that the second limiting block 8 is separated from the second limiting groove 6. At this time, the upper silica gel pad 1 is moved to the right, so that the second limiting block 8 enters the first limiting groove 2, so that the upper silica gel pad 1 and the second silica gel sheet 7 are attached together, so that the thickness of the heat-conducting pad piece is reduced. When it is necessary to continue to reduce the thickness, the upper silica gel pad 1 is moved to the left, so that the second silica gel sheet 7 is taken out, so that the third limiting block 12 is separated from the third limiting groove 10. The upper silica gel pad 1 is moved to the right, so that the third limiting block 12 enters the first limiting groove 2, so that the upper silica gel pad 1 and the lower silica gel pad 11 are attached together, so that the overall thickness of the heat-conducting pad piece is further reduced. Through the inverted taper structure of the first anti-skid block 5, the second anti-skid block 9 and the third anti-skid block 13, when the first limiting block 4, the second limiting block 8 and the third limiting block 12 enter the first limiting groove 2, the second limiting groove 6 and the third limiting groove 10 respectively, it is more labor-saving. When the first limiting block 4, the second limiting block 8 and the third limiting block 12 are taken out from the first limiting groove 2, the second limiting groove 6 and the third limiting groove 10 respectively, the resistance is relatively large, so that the stability of the upper silica gel pad 1, the first silica gel sheet 3, the second silica gel sheet 7 and the lower silica gel pad 11 when they are placed is further improved. When the thickness of the heat-conducting pad piece is relatively small, the upper silica gel pad 1 is moved to the left, a new first silica gel sheet 3 is added, so that the first limiting block 4 on the original first silica gel sheet 3 enters the second limiting groove 6 on the new first silica gel sheet 3. The upper silica gel pad 1 is moved to the right, so that the first limiting block 4 on the new first silica gel sheet 3 enters the first limiting groove 2, so that the overall thickness of the heat-conducting pad piece is increased. When the thickness of the heat-conducting pad piece is not enough, the new first silica gel sheet 3 is continuously added, and the above steps are repeated, so that the thickness of the heat-conducting pad piece is further increased, so that the device is convenient for adjusting the thickness of the heat-conducting pad piece.The heat-conducting gasket can meet the requirement of different thickness, and the heat-conducting gasket does not need to be additionally purchased in different thickness, thereby improving the convenience of the heat-conducting gasket, and the upper silica gel pad 1, the first silica gel sheet 3, the second silica gel sheet 7 and the lower silica gel pad 11 have high friction, so that the upper silica gel pad 1, the first silica gel sheet 3, the second silica gel sheet 7 and the lower silica gel pad 11 are prevented from being deviated, and the heat-conducting efficiency of the heat-conducting gasket is affected.
[0032] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
