Please refer to Figures 4 to 7, each of which is a side sectional view of the panel fixing device and the second panel before, during, and after assembly and a perspective view of multiple panel fixing devices and the second panel after assembly, which are disclosed below The assembly state described above:

When assembling the sheet fixing device with the first sheet 4 and the second sheet 5, firstly make the first sheet 4 stack above the second sheet 5, and make the first through hole 40 of the first sheet 4 align with the second sheet 5 The second through hole 50 is applied to press and drive the cap 2 to compress the second elastic member 24, and the clamping part 112 of the plate fixing device is inserted into the first through hole 40 of the first plate 4 from top to bottom, At this time, the fixing element 3 moves downward to form the stop plate 34 completely protruding from the bottom side of the main body 11 of the sleeve 1, and the plurality of elastic pieces 111 of the main body 11 are held against the first through hole 40 by the engaging part 112 during the insertion process. The surrounding wall surface is retracted, and the narrower part below the rod body 33 of the fixing element 3 forms a shrinkage space for the elastic piece 111. After the clamping part 112 passes through the first through hole 40, the multiple elastic pieces 111 and the clamping part 112 form an elastic Reset, so that the plate fixing device and the first plate 4 form a temporary positioning (as shown in Figure 4). Continue to push and drive the cap 2 downward so that the engaging portion 112 is inserted into the second through hole 50 of the second plate 5. During the insertion process, the plurality of elastic pieces 111 and the engaging portion 112 of the main body 11 are also received by the second through hole. 50, the surrounding walls resist to produce shrinkage, and after passing through the second through hole 50, an elastic reset is also formed, and at the same time, the resisting of the top side of the clamping part 112 The edge 1121 abuts against the bottom surface of the preset second plate 5 to form a position (as shown in FIG. 5 ). At this time, after removing the applied force to the driving cap 2, the driving cap 2 is bounced upward by the reset force of the second elastic member 24 and at the same time drives the fixing element 3 to move upward, so that the upper edge of the stop disc 34 of the fixing element 3 sticks Close to the bottom side of the main body 11 (as shown in Figure 6), and through the elastic reset force of the second elastic member 24 to keep the abutting edge 1121 of the engaging part 112 to maintain a proper abutting force, the second plate 5 can be prevented from The bottom surface is damaged by extrusion, and the assembly of the plate fixing device and the two plates is completed through the above.

As shown in Figure 7, the above-mentioned first plate 4 refers to a heat sink and is provided with a plurality of first through holes 40 in the heat sink, and the second plate 5 refers to a circuit board and the circuit board is provided with corresponding The position and quantity of the first through hole 40 are multiple second through holes 50, and the circuit board can be further provided with a preset heating element 6 (such as: CPU [central processing unit], GPU [graphics processing unit] or power element), The top surface of the preset heating element 6 is attached to the bottom surface of the heat sink, and the heat energy is conducted to the air through the heat sink to achieve the purpose of heat dissipation. Moreover, the upper surface of the preset first plate 4 formed by the heat sink is elastically resisted by the first elastic member 13.

Next, when the preset heating element 6 cools down and the thickness of the first plate 4 is reduced, the compression amount of the first elastic member 13 is reduced (lengthened) to maintain the resisting force. Through the aforementioned actions, the upper surface of the first plate 4 can have the effect of permanently maintaining the moderate elastic resistance force.

The main technical feature of this creation is that the plate fixing device is inserted through the clamping part 112 of the sleeve 1 behind the first through hole 40 of the preset first plate 4 and the second through hole 50 of the preset second plate 5 , and make the abutment edge 1121 on the top side of the clamping part 112 abut against the bottom surface of the preset second plate 5 to form Positioning, and through the elastic reset force of the second elastic member 24, the abutting edge 1121 of the engaging portion 112 maintains an appropriate abutting force. Since the upper surface of the preset first plate 4 is held against by the first elastic member 13 to form elastic positioning, the upper surface of the preset first plate 4 can be prevented from being squeezed and damaged. When the thickness is changed due to thermal expansion and contraction, the first elastic member 13 can be adjusted at a small distance to maintain proper resistance force. In addition, the plate fixing device can be locked without any tools, which has excellent assembly convenience. This creation is applied in the field of plate assembly that does not need to be resisted by urgent force, and has excellent practicability, so a patent application is filed to seek the protection of the patent right.

The above is only a preferred embodiment of this creation, and does not limit the patent scope of this creation. Therefore, all simple modifications and equivalent structural changes made by using the instructions and drawings of this creation should be included in this creation in the same way. Within the scope of the patent, I will cooperate with Chen Ming.
