The protective component 3 is disposed inside the mounting frame 1 and is used to protect the graphene plate 2. The protective component 3 includes a pressure-resistant component 31 and a shock-absorbing component 32. The pressure-resistant component 31 is disposed at the top of the inner cavity of the mounting frame 1 and at the top of the graphene plate 2.

The shock-absorbing component 32 is disposed inside the mounting frame 1 and at the bottom of the graphene plate 2. The shock-absorbing component 32 can also cooperate with the pressure-resistant component 31 to further protect the graphene plate 2 from pressure.

[0040] Furthermore, the protective component 3 also includes a base plate 34 and a heat insulation plate 33. The base plate 34 is fixedly connected to the bottom of the inner cavity of the mounting frame 1 and is located at the bottom of the shock-absorbing component 32. The heat insulation plate 33 is sleeved inside the mounting frame 1 and is located between the shock-absorbing component 32 and the graphene plate 2.

[0041] In particular, the pressure-resistant component 31 includes a fixing plate 311, a heat-conducting plate 312, and a sealing film 313. The fixing plate 311 is fixedly connected to the top of the inner cavity of the mounting frame 1.

The connecting assembly 4 also includes a locking rod 44, a connecting block 45, and an inner bolt 46. The outer wall of the locking rod 44 is slidably inserted into the connecting plate 41. The first fixing block 42 and the second fixing block 43 each have a slot on their opposite sides that matches the locking rod 44. The locking rod 44 is engaged in the slot between the first fixing block 42 and the second fixing block 43, which allows the two mounting frames 1 to be spliced ​​and fixed, thereby ensuring the stability of the two adjacent mounting frames 1 when they are connected. The connecting block 45 is fixedly connected to one end of the locking rod 44 and is fixedly connected to one end of the connecting plate 41 by the inner bolt 46. By removing the inner bolt 46 and using the connecting block 45 to pull out the locking rod 44, the first fixing block 42 and the second fixing block 43 can be unlocked, thereby allowing the adjacent mounting frames 1 to be separated.
