The fixing plate 10 is a substantially strip-shaped flat plate and is disposed in the circumferential direction of the plate 30. In this embodiment, the plate 30 is a rectangular flat plate, and the fixing plate 10 is disposed on four sides of the plate 30 along four edges of the plate 30. The fixing mechanism 20 is disposed at the middle and the corner of the fixing plate 10, and configured to abut against the middle and the corner of the edge of the plate 30 to fix the plate 30. In this embodiment, the plate fixing device includes 3 pairs of the fixing mechanisms 20, and each pair of the fixing mechanisms 20 is symmetrical with respect to the center of the plate 30. 2 pairs of the plates are arranged at four corners of the plate 30, and the other 1 pair of the plates are arranged at the middle point of the edge of the plate 30.

Fig. 2 is a schematic structural view of the fixing plate 10. As shown in fig. 2, the fixing plate 10 is provided with a recessed mounting location 11, and the mounting location 11 is used for mounting the fixing mechanism 20. The installation position 11 includes a fitting region 111, the fitting region 111 is a through hole penetrating through the fixing plate 10, and the shape of the fitting region 111 corresponds to the shape of the fixing mechanism 20 to install the fixing mechanism 20.

Fig. 3 is a schematic structural view of the fixing mechanism 20, and fig. 4 is an exploded view of the fixing mechanism 20 in fig. 3. As shown in fig. 3 and 4, the fixing mechanism 20 includes a fixing block 21, a clamp block 22, a locking mechanism, a first connecting member 212, and a second connecting member 231.

The fixing block 21 is substantially square, and penetrates through the fixing plate 10 through a first connecting member 212 to connect the fixing block 21 so as to fix the fixing block 21 to one side surface of the fixing plate 10. In this embodiment, the first connecting member 212 is a screw, and the first connecting member 212 is connected to the screw hole on the bottom surface of the fixing block 21 after passing through the fixing plate 10 from the bottom surface of the fixing plate 10, so as to mount the fixing block 21 on the fixing plate 10.

The fixing block 21 includes an adjusting through hole 211, a cross section of the adjusting through hole 211 is an ellipse, and a major axis direction of the adjusting through hole 211 extends in a radial direction of the sheet material 30. The second connector 231 passes through the adjustment through hole 211 to be connected to the clamping block 22, thereby connecting the clamping block 22 to the fixing block 21. Also, since the long axis direction of the adjustment through hole 211 extends in a direction approaching or separating from the slab 30, the clamp block 22 may move in a direction approaching or separating from the slab 30 with the second connection member 231 fixed.

Fig. 5 is a schematic view of the cleat block 22. As shown in fig. 5, the splint block 22 includes a splint surface 222 coupled to the fixing block 21 by a second coupling member 231 such that the splint surface 222 of the splint block 22 contacts a side surface of the slab 30 to fix the slab 30. In this embodiment, the second connector 231 is a screw, and a threaded end passes through the adjustment through hole 211 and is connected to a screw hole of the clamp block 22. The clamp block 22 is inserted into the mounting position 11, and the surface of the clamp block 22 is flush with the surface of the fixing plate 10. The clamping plate surface 222 includes a boss 223 corresponding to the engaging region 111, and when the clamping plate 22 clamps the plate 30, the boss 223 is inserted into the engaging region 111 to fix the clamping plate 22 to the fixing plate 10. The bosses 223 extend in a straight line of a horizontal plane or in a right-angle direction of the horizontal plane. The fixing mechanism 20 further includes a spring 221, one end of the spring 221 abuts against the clamping plate block 22, and the other end abuts against the side wall of the installation position 11, so as to apply an acting force to the clamping plate block 22 in a direction away from the fixing plate 10.

The anti-loosening component comprises a rotary loosening and clamping block 23 and a spring fixing block 24. The second connecting member 231 penetrates through the rotation releasing block 23 and the fixing block 21 to be connected to the clamping block 22 so as to fix the fixing block 21 and the clamping block 22. In this embodiment, the number of the second connecting members 231 is two, and the second connecting members pass through both ends of the rotation releasing block 23. The spring fixing block 24 comprises a spring 242, the spring fixing block 24 is connected to the fixing block 21 through a third connecting piece 241, one end of the rotary clamping block 23 abuts against the spring fixing block 24, and the free end of the spring 242 abuts against the other end of the rotary clamping block 23.

When in use, the splint block 22 is firstly placed in the installation position 11 of the fixing plate 10, and the boss 223 of the splint block 22 is embedded in the embedding area 111 of the installation position 11, so that the splint surface 222 of the splint block 22 is abutted against the side surface of the plate 30 under the restoring force of the spring 221.

Then, the first connecting member 212 is connected to the fixing block 21 through the fixing plate 10 from the bottom of the fixing plate 10 to fix the fixing block 21 on the fixing plate 10, at this time, the fixing block 21 is located above the clamping plate block 22, and the fixing block 21 is pressed against the clamping plate block 22 by the tensile force of the first connecting member 212, so that the fixing block 21 and the clamping plate block 22 can be fixed on the fixing plate 10.

Then, the second connecting member 231 is connected to the threaded hole of the clamping block 22 through the adjusting through holes 211 of the rotating loose clamping block 23 and the fixing block 21, and is connected to the threaded hole of the fixing block 21 through the third connecting member 241 through the spring fixing block 24 to fix the spring fixing block 24, so that the spring 242 of the spring fixing block 24 is abutted to the rotating loose clamping block 23, thereby preventing the rotating loose clamping block 23 from rotating and playing a role in preventing the second connecting member 231 from loosening.

When the fixing mechanism 20 is installed, the fixing block 21 is fixed to the fixing plate 10 by the first connecting member 212, and the rotation releasing block 23 and the clamping block 22 are integrated by the second connecting member 231 and can be moved in a direction away from the plate 30 or close to the plate 30 relative to the fixing block 21 to adjust the position thereof, so that the plate 30 can be installed again or the plate 30 can be removed.

The fixing mechanisms 20 of the plate fixing device connect the fixing block 21 to the fixing plate 10, the clamping plate 22 is connected to the fixing plate 10, and the clamping plate surface 222 of the clamping plate 22 is in contact with the plate 30, so that the clamping plates of the fixing mechanisms 20 can oppositely push against the side surface of the plate 30 to fix the plate 30, thereby avoiding the abrasion of the clamping area of the plate 30 caused by clamping the plate 30, and the plate 30 can be installed and disassembled by pulling the rotating loose clamping block 23 and the clamping plate 22, which is convenient to operate and effectively improves the efficiency of installing and disassembling the plate 30.
