The bottom surfaces of twelve glass plates 7 are mounted on the lower plate 1 by pressing assemblies 6, and the two sides of the twelve glass plates 7 are located at the first coating holes 102 of the lower plate 1 and the second coating holes 201 of the upper plate 2. The upper plate 2 is connected with the lower plate 1 by the eight self-locking structures 3. The bottom surface of the upper plate 2 is connected with the twelve glass plates 7 by the pressing assemblies 6, and the pressing assemblies 6 are fixed on the bottom of the upper plate 2 and located inside the adjacent two second coating holes 201.
[0027] The upper plate 2 and the lower plate 1 are used to fix the glass plates 7 and expose the two sides of the glass plates 7 for coating. The pressing assemblies 6 are used to compact the glass plates 7 and elastically contact with the glass plates 7 to avoid damage of the glass plates 7 caused by rigid contact. The self-locking structures 3 are used to automatically lock the upper plate 2 on the lower plate 1 and facilitate unlocking and dismounting of the upper plate 2 from the lower plate 1.
[0028] As shown, Figures 4-7 Each self-locking structure 3 comprises a self-locking part 32 and a locked part 31. The self-locking part 32 comprises a spring cover plate 321, a pivot shaft seat 322, a pivot shaft (not shown in the figure), two reset springs 323, a rotating part 324 and a self-locking seat 325. The locked part 31 comprises a protective cover 311 and a lock catch 312. The rotating part 324 is rotatably installed on the pivot shaft seat 322 by the pivot shaft, and the two reset springs 323 are sleeved on the pivot shaft. One end of the two reset springs 323 is embedded into two spring grooves of the pivot shaft seat 322, and the spring cover plate 321 covers the top of the two spring grooves. The spring cover plate 321 is connected with the pivot shaft seat 322 by bolts. One end of the reset spring 323 is limited in the spring groove, and the other end of the reset spring 323 abuts against the rotating part 324. One end of the rotating part 324 penetrates through the spring cover plate 321, and the one end of the rotating part 324 can be embedded into the lock catch 312. The other end of the rotating part 324 is located at the unlocking hole 103 of the lower plate 1. The lock catch 312 is installed around the upper plate 2 by the protective cover 311.
[0029] The cooperation of the self-locking part 32 and the locked part 31 can automatically lock the self-locking part 32 with the locked part 31 under the action of upward pressure, and can disconnect the self-locking part 32 from the locked part 31 under the action of downward force. The spring cover plate 321 is used to limit the reset spring 323 to avoid disengagement from the limitation of the pivot shaft seat 322. The pivot shaft seat 322 is used to fix the pivot shaft and limit the reset spring 323. The pivot shaft is used to install the reset spring 323 and the rotating part 324 on the pivot shaft seat 322. The reset spring 323 provides power for the reset of the rotating part 324. The rotating part 324 is used to lock the lock catch 312. The self-locking seat 325 is used to install the pivot shaft seat 322 on the lower plate 1. The protective cover 311 is used to install and protect the lock catch 312. The lock catch 312 is used to limit the rotating part 324 to prevent the upper plate 2 from disengaging from the lower plate 1.
[0030] AsFigure 6 As shown, the rotating member 324 includes an unlocking plate 324a and a locking hook 324b. The unlocking plate 324a and the locking hook 324b are perpendicularly connected. A shaft hole is provided at the junction of the unlocking plate 324a and the locking hook 324b, through which the rotating shaft passes. The back of the locking hook 324b is provided with two spring mounting grooves 324c and a spring pressure surface 324d. The two spring mounting grooves 324c are connected to the shaft hole.

The unlocking plate 324a is parallel to the lower plate 1 and is located within the unlocking hole 103 of the lower plate 1.
[0031] The working process of the self-locking mechanism 3 is as follows: When the upper plate 2 is stacked on the lower plate 1, the upper plate 2 drives the lock catch 312 to move downward. The lock catch 312 presses against the rotating member 324, which rotates along the rotation axis. When the rotating member 324 rotates a certain angle, the rotating member 324 is released from the pressure of the lock catch 312. Under the elastic force of the return spring 323, the rotating member 324 rotates upward, and the locking hook 324b of the rotating member 324 fully enters the lock catch 312, thereby automatically locking the upper plate 2 and the lower plate 1. When unlocking is required, the unlocking plate 324a of the rotating member 324 is pressed against the unlocking hole 103 of the lower plate 1. The unlocking plate 324a rotates upward along the rotation axis, and the locking hook 324b is driven by the unlocking plate 324a to rotate. When the locking hook 324b rotates a certain angle upward, the locking hook 324b is released from the lock catch 312, thereby locking the upper plate 2 and the lower plate 1.
