[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides an assembled steel trestle board, such as Figures 1-6As shown, an assembled steel trestle board comprises a first panel 1 and a second panel 2, a supporting mechanism is installed on the upper surface of the first panel 1, and the supporting mechanism comprises a plug-in slot 11 opened in a rectangular array on the upper surface of the first panel 1, both inner walls of the plug-in slot 11 are fixedly connected with spring steel 12, and opposite sides of the two spring steels 12 are fixedly connected with sliding blocks 13 slidably connected with the plug-in slot 11, and opposite sides of the two sliding blocks 13 are jointly fitted and clamped with an arched support block 14. Before the first panel 1 and the second panel 2 are assembled, the arched support block 14 is inserted into the interior of the plug-in slot 11, and the knob is turned to rotate the bidirectional threaded rod 15, thereby making the corresponding connecting plates 16 approach each other, so that the connecting plates 16 drive the sliding block 13 to slide inside the plug-in slot 11, so that the sliding block 13 clamps and clamps the arched support block 14, so that the arched support block 14 is clamped into the interior of the plug-in slot 11, completing the assembly of the arched support block 14;

[0030] The support mechanism also includes a plurality of bidirectional threaded rods 15 rotatably connected to the inside of the first panel 1, and every two corresponding bidirectional threaded rods 15 are fixedly connected, and both sides of the surface of each bidirectional threaded rod 15 are threadedly connected with a connecting plate 16, and a plurality of connecting plates 16 are respectively fixedly connected to the corresponding sliding blocks 13, and the connecting plate 16 is slidably connected to the first panel 1, wherein one end of the three bidirectional threaded rods 15 is fixedly connected with a knob, and the sliding block 13 is supported by the setting of the spring steel 12, so that the arched support block 14 is more stable when in use, and a groove 17 corresponding to the knob is opened in a path array on one side of the first panel 1. Through the setting of the groove 17, the knob will not affect the splicing of multiple assembled steel trestle plates;

[0031] The upper surfaces of several arched support blocks 14 are jointly fitted with a pressing plate 18. The upper surface of the pressing plate 18 is fixedly connected to an elastic pressing rod 19 fixedly connected to the second panel 2 in a rectangular array. The four corners of the upper surface of the first panel 1 are fixedly connected to a hollow sleeve 3. The plug-in assembly includes four plug-in blocks 20 respectively fixedly connected to the four corners of the lower surface of the second panel 2. Both sides of the surface of the plug-in block 20 are provided with a snap-in groove 21 corresponding to the snap-in plate 9. The four plug-in blocks 20 correspond to the four hollow sleeves 3 one by one. The four plug-in blocks 20 are respectively plugged into the hollow sleeves 3. The inside of the sleeve 3 makes the plug-in block 20 push the lower pressure plate 22 to slide inside the hollow sleeve 3. Both sides of the hollow sleeve 3 are rotatably connected to the rotating plate 4 through the rotating shaft. One side of the rotating plate 4 is rotatably connected to the clamping plate 5 through the rotating shaft. Both sides of the clamping plate 5 are fixedly sleeved with a torsion spring 6 fixedly connected to the rotating plate 4. The elastic force of the torsion spring 6 not only makes the clamping plate 5 automatically reset, which is convenient for next use, but also makes the clamping plate 5 not cause movement obstacles to the reset of the lower pressure plate 22, thereby making the assembled steel trestle plate more convenient during installation and disassembly;

[0032] The upper surface of the rotating plate 4 is rotatably connected to the linkage plate 7 through a pin shaft. The upper surface of the linkage plate 7 is rotatably connected to a moving plate 8 slidably connected to the hollow sleeve 3 through a pin shaft. One side of the moving plate 8 is fixedly connected to a clamping plate 9. When the lower pressing plate 22 moves, the lower pressing plate 22 pushes the clamping plate 5 to move, so that the rotating plate 4 rotates inside the hollow sleeve 3, driving the linkage plate 7 to rotate synchronously, so that the moving plate 8 drives the clamping plate 9 to slide inside the hollow sleeve 3. The four corners on one side of the clamping plate 9 are fixedly connected to the hollow sleeve 3. The spring assembly 10, through the movement of the plug-in block 20, enables the clamping plate 9 to be plugged into the clamping groove 21, thereby limiting the plug-in block 20 through the clamping plate 9, so that the plug-in block 20 is clamped into the hollow sleeve 3, thereby completing the assembly of the first panel 1 and the second panel 2, the elastic force of the torsion spring 6 is greater than the elastic force of the spring assembly 10, and the elastic force of the torsion spring 6 is greater than the elastic force of the spring assembly 10, so that when the lower pressure plate 22 pushes the clamping plate 5 to move, the clamping plate 5 will not flip over, so that the clamping plate 5 can drive the rotating plate 4 to rotate;

[0033] The abutting plate 5 and the linkage plate 7 are both rotatably connected to the hollow sleeve 3, and the movable plate 8 is slidably connected to the hollow sleeve 3. Since the clamping plate 9 is inserted into the inside of the clamping groove 21, the rotating plate 4 cannot rotate, so that the abutting plate 5 and the torsion spring 6 rotate, so that the abutting plate 5 is no longer in contact with the lower pressure plate 22;

[0034] The four corners of the lower surface of the second panel 2 are equipped with plug-in components, and the interior of the hollow sleeve 3 is slidably connected to a lower pressure plate 22 corresponding to the tightening plate 5. The four corners of the lower surface of the lower pressure plate 22 are fixedly connected to a buffer spring 23, and the buffer spring 23 is fixedly connected to the inner bottom wall of the hollow sleeve 3. The middle part of the lower surface of the lower pressure plate 22 is fixedly connected to an unlocking rod 24 slidably connected to the hollow sleeve 3. When the assembled steel trestle board needs to be disassembled, the unlocking plate 25 on the first panel 1 is removed, so that the unlocking rod 24 can be pulled downward, so that the unlocking rod 24 drives the lower pressure plate 22 to move, so that the lower The pressure plate 22 pushes the clamping plate 5 to continue moving inside the hollow sleeve 3. One end of each two corresponding unlocking rods 24 passes through the first panel 1 and is fixedly connected to the unlocking plate 25. The unlocking plate 25 is fixedly connected to the first panel 1 by bolts. The elastic force of the spring assembly 10 resets the clamping plate 9, so that the rotating plate 4 and the linkage plate 7 are automatically reset, so that the clamping plate 9 is no longer clamped with the clamping groove 21, and the plug-in block 20 is no longer clamped with the hollow sleeve 3, so that the first panel 1 and the second panel 2 are no longer clamped, and the two unlocking plates 25 are both stored on both sides of the lower surface of the first panel 1.

[0035] When the first and second panels 1 and 2 are assembled, the first and second panels 1 and 2 are assembled, and the first and second panels 2 are assembled, respectively.

[0036] Before assembling the first panel 1 and the second panel 2, the arched support block 14 is inserted into the interior of the plug-in slot 11, and the knob is turned to rotate the bidirectional threaded rod 15, so that the corresponding connecting plates 16 are close to each other, so that the connecting plates 16 drive the sliding block 13 to slide inside the plug-in slot 11, so that the sliding block 13 clamps and engages the arched support block 14, so that the arched support block 14 is engaged with the interior of the plug-in slot 11, completing the assembly of the arched support block 14, and the spring steel 12 is provided to support the sliding block 13, so that the arched support block 14 is more stable when in use;

[0037] When the assembled steel trestle board needs to be disassembled, the unlocking plate 25 on the first panel 1 is removed, so that the unlocking rod 24 can be pulled downward, so that the unlocking rod 24 drives the lower pressure plate 22 to move, so that the lower pressure plate 22 pushes the clamping plate 5 to continue to move inside the hollow sleeve 3. Since the clamping plate 9 is inserted into the inside of the clamping groove 21, the rotating plate 4 cannot be rotated, so that the clamping plate 5 and the torsion spring 6 rotate, so that the clamping plate 5 is no longer in contact with the lower pressure plate 22, thereby releasing the spring assembly 10. The elastic force causes the clamping plate 9 to reset, thereby causing the rotating plate 4 and the linkage plate 7 to reset automatically, so that the clamping plate 9 is no longer clamped with the clamping groove 21, and the plug-in block 20 is no longer clamped with the hollow sleeve 3, so that the first panel 1 and the second panel 2 are no longer clamped, and the elastic force of the torsion spring 6 not only causes the clamping plate 5 to reset automatically, which is convenient for next use, but also causes the clamping plate 5 to not cause movement obstacles to the reset of the lower pressure plate 22, thereby making the assembled steel trestle plate more convenient during installation and disassembly.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
