[0012] 3. Beneficial effects The present invention provides a connection structure between a column and a laminate. It has the following beneficial effects: 1. The present invention provides a connecting structure between a column and a shelf board. Inside the installation groove of the sliding block, a first top block and a second top block are slidably arranged. Two tension springs are arranged between the first top block and the second top block through an installation ring. A wedge block is slidably arranged inside the connecting groove opened in the installation block. The inclined surfaces of the wedge block are respectively in contact with the first top block and the second top block. At the same time, fixed blocks are arranged on both sides inside the connecting groove, and sliding grooves are opened in the fixed blocks. Sliders are arranged on both sides of the wedge block, and the sliders are slidably connected with the sliding grooves. A third bolt is threadedly connected inside the cover plate, and at the same time, a male-female buckle is arranged on the surface of the cover plate, and a female-male buckle is arranged on the surface of the installation plate. When in use, after moving the sliding block to a suitable position, rotate the third bolt so that the third bolt moves towards the inside of the connecting groove. During the movement, the third bolt will contact the wedge block, and then drive the wedge block to move towards the first top block and the second top block. Because the first top block and the second top block are in contact with the inclined surfaces of the wedge block, when the wedge block moves, it will drive the first top block and the second top block to move in opposite directions. At this time, the first top block and the second top block will drive the tension springs to stretch, so that the parts of the first top block and the second top block extending out of the installation block become more until the first top block and the second top block are tightly pressed against the inner wall of the sliding groove. Then use the fourth bolt to connect the installation plate and the shelf board. Then, snap the female-male buckle on the installation plate and the male-female buckle on the cover plate to complete the connection between the shelf board and the column. When it is necessary to move the shelf board, separate the female-male buckle and the male-female buckle, and then remove the shelf board. Then rotate the third bolt so that the third bolt moves in the opposite direction of the first top board and the second top board, so that the wedge block no longer receives the force towards the first top block and the second top block. Then, under the action of the tension springs, the first top block and the second top block will move towards each other, so that the first top block and the second top block no longer move along the inner wall of the sliding groove. At this time, the sliding block can slide inside the sliding groove. Then move the sliding block to a suitable position, and then rotate the third bolt so that the first top block and the second top block tightly press against the inner wall of the sliding groove. Then snap the female-male buckle and the male-female buckle to complete the connection. When in use, it is convenient to adjust the height of the shelf board, so that the height of the shelf board can be freely adjusted according to needs, and the flexibility is higher when in use.
[0013] 2. The present invention provides a connection structure between a column and a shelf board. By providing a positioning rod, a first clamping block is arranged at one end of the positioning rod, and a placement groove is opened at the other end. A second clamping block is slidably arranged inside the placement groove. During the installation of the shelf board, two columns are required to install the shelf board. Sliding blocks are installed inside both columns. When in use, first insert the first clamping block into a positioning groove opened in a cover plate installed inside one of the columns, push the second clamping block into the interior of the placement groove, then align the placement groove with a positioning groove in a cover plate installed inside the other column, and then push the second clamping block into the positioning groove. Then rotate the nut, and the nut will drive the top ring to move on the threaded rod, driving the top ring to tightly press against the mounting rod. After use, hold the positioning rod and move the positioning rod, which will drive the sliding blocks installed inside the two columns to move synchronously. When in use, the positions of the two sliding blocks inside the columns can be kept the same, facilitating the installation of the shelf board. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the specific implementation manners of the present invention, all other specific implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Detailed implementation manner 1: As Figures 1-10 shown, the specific implementation manner of the present invention provides a connection structure between a column and a shelf board, including a column 1, a shelf board 24 and a positioning rod 28. A sliding groove 2 is opened inside the column 1, a sliding block 3 is slidably connected inside the sliding groove 2, one end of the sliding block 3 is fixedly connected with a mounting block 4, four second bolts 9 are threadedly connected inside the sliding block 3, one end of the four second bolts 9 is jointly slidably connected with a baffle 10, two first bolts 5 are threadedly connected inside the mounting block 4, and one end of the two first bolts 5 is jointly slidably connected with a cover plate 6; The sliding block 3 is internally provided with an installation groove 11. One side inside the installation groove 11 is slidably connected with a first top block 12. One end of the first top block 12 extends to the outside of the installation block 4. The side inside the installation groove 11 far from the first top block 12 is slidably connected with a second top block 13. One end of the second top block 13 extends to the outside of the installation block 4. In actual use, the first top block 12 and the second top block 13 can move towards each other or in opposite directions inside the installation groove 11, so as to change the size of the parts of the first top block 12 and the second top block 13 exposed outside the installation block 4. Two guide rods 14 are fixedly connected to one side surface of the first top block 12. Two relief grooves 15 corresponding to the guide rods 14 are opened inside the second top block 13. Two mounting rings 16 are fixedly connected to the corresponding side surfaces of the first top block 12 and the second top block 13. A tension spring 17 is respectively connected between two corresponding mounting rings 16 among the four mounting rings 16. The two guide rods 14 are used to guide the first top block 12 and the second top block 13 to move linearly along the guide rods 14. The relief grooves 15 are provided so that the guide rods 14 can be smoothly inserted and allow relative movement between the first top block 12 and the second top block 13. The tension springs 17 enable the first top block 12 and the second top block 13 to return to their original positions after being acted on by an external force; A connection groove 18 is opened inside the installation block 4. Two mirror-image fixed blocks 21 are fixedly connected inside the connection groove 18. Two sliding grooves 22 are opened inside the two fixed blocks 21. A wedge-shaped block 19 is slidably connected inside the connection groove 18. The two inclined surfaces of the wedge-shaped block 19 are respectively in contact with the first top block 12 and the second top block 13. Two sliders 20 are fixedly connected to both ends of the wedge-shaped block 19. The sliders 20 extend into the sliding grooves 22 and are slidably connected with the side walls of the sliding grooves 22. During the use process, because the inclined surfaces of the wedge-shaped block 19 are in contact with the first top block 12 and the second top block 13, when the wedge-shaped block 19 moves towards the first top block 12 and the second top block 13, it will drive the first top block 12 and the second top block 13 to move in opposite directions, thereby driving the two tension springs 17 to stretch. A third bolt 23 is threadedly connected inside the cover plate 6. One end of the third bolt 23 extends into the installation block 4 and abuts against the surface of the wedge-shaped block 19. A male and female snap fastener male part 7 is fixedly connected to the surface of the cover plate 6. A positioning groove 8 is opened inside one side of the cover plate 6. When the third bolt 23 is screwed, it will drive the third bolt 23 to move towards the inside of the installation block 4. After that, one end of the third bolt 23 will contact the wedge-shaped block 19 and drive the wedge-shaped block 19 to move. Two fourth bolts 25 are slidably connected inside both sides of the laminate 24. One ends of the two fourth bolts 25 penetrate through the side walls of the laminate 24 and are commonly threadedly connected with a mounting plate 26. A male and female snap fastener female part 27 corresponding to the male and female snap fastener male part 7 is fixedly connected to the surface of the mounting plate 26. The male and female snap fastener female part 27 corresponds to the male and female snap fastener male part 7, so that the laminate 24 can be quickly and stably connected. When connection is required, just align the male and female snap fastener female part 27 with the male and female snap fastener male part 7 and press them down to achieve tight connection between the two. When disassembly is required, simply separate the two; One end of the positioning rod 28 is fixedly connected with a first clamping block 29. A placement groove 30 is formed inside one end of the positioning rod 28. A second clamping block 31 is slidably connected inside the placement groove 30. A threaded rod 32 is fixedly connected to the surface of the second clamping block 31. One end of the threaded rod 32 extends out of the placement groove 30 and is slidably sleeved with a top ring 33. The surface of the top ring 33 abuts against the surface of the positioning rod 28. A nut 34 is threadedly sleeved on one end of the threaded rod 32. During use, first insert the first clamping block 29 into the positioning groove 8 formed in the cover plate 6 installed inside one of the columns 1. Push the second clamping block 31 into the inside of the placement groove 30. Then align the placement groove 30 with the positioning groove 8 inside the cover plate 6 installed inside the other column 1. Then push the second clamping block 31 into the inside of the positioning groove 8. Then rotate the nut 34. The nut 34 will drive the top ring to move on the threaded rod 32, driving the top ring 33 to be tightly pressed against the positioning rod 28. After use, hold the positioning rod 28 and move the positioning rod 28, which will drive the sliding blocks 3 installed inside the two columns 1 to move synchronously. During use, the positions of the two sliding blocks 3 inside the columns 1 can be kept the same.
[0018] In this embodiment, a first top block 12 and a second top block 13 are slidably arranged inside the installation groove 11 inside the sliding block 3. Two tension springs 17 are arranged between the first top block 12 and the second top block 13 through an installation ring 16. A wedge block 19 is slidably arranged inside the connection groove 18 opened in the installation block 4. The inclined surfaces of the wedge block 19 are respectively in contact with the first top block 12 and the second top block 13. At the same time, fixing blocks 21 are arranged on both sides inside the connection groove 18. A sliding groove 22 is opened in the fixing block 21. Sliders 20 are arranged on both sides of the wedge block 19. The sliders 20 are slidably connected with the sliding groove 22. A third bolt 23 is threadedly connected inside the cover plate 6. At the same time, a female and male snap fastener sub - buckle 7 is arranged on the surface of the cover plate 6, and a female and male snap fastener mother - buckle 27 is arranged on the surface of the installation plate 26. When in use, after moving the sliding block 3 to a suitable position, rotate the third bolt 23 so that the third bolt 23 moves into the connection groove 18. During the movement, the third bolt 23 will contact the wedge block 19 and drive the wedge block 19 to move towards the first top block 12 and the second top block 13. Since the first top block 12 and the second top block 13 are in contact with the inclined surfaces of the wedge block 19, the movement of the wedge block 19 will drive the first top block 12 and the second top block 13 to move in opposite directions. At this time, the first top block 12 and the second top block 13 will drive the tension springs 17 to stretch, so that the parts of the first top block 12 and the second top block 13 extending out of the installation block 4 become more until the first top block 12 and the second top block 13 are tightly pressed against the inner wall of the sliding groove 2. Then, use the fourth bolt 25 to connect the installation plate 26 and the layer board 24. Then, snap - connect the female and male snap fastener mother - buckle 27 on the installation plate 26 and the female and male snap fastener sub - buckle 7 on the cover plate 6, and the connection between the layer board 24 and the column 1 can be completed. When it is necessary to move the layer board 24, first separate the female and male snap fastener mother - buckle 27 and the female and male snap fastener sub - buckle 7, and remove the layer board 24. Then, rotate the third bolt 23 to move it in the opposite direction of the first top block 12 and the second top block 13. The wedge block 19 no longer receives the force towards the first top block 12 and the second top block 13. Under the action of the tension springs 17, the first top block 12 and the second top block 13 will move towards each other and no longer be tightly pressed against the inner wall of the sliding groove 2. At this time, the sliding block 3 can slide inside the sliding groove 2. After moving the sliding block 3 to a suitable position, rotate the third bolt 23 again to make the first top block 12 and the second top block 13 tightly press against the inner wall of the sliding groove 2. Finally, snap - connect the female and male snap fastener mother - buckle 27 and the female and male snap fastener sub - buckle 7, which is convenient for adjusting the height of the layer board 24, so that the height of the layer board 24 can be freely adjusted according to requirements, improving the flexibility of use.
[0019] Working principle: S1: First, accurately insert the first clamping block 29 of the positioning rod 28 into the positioning slot 8 of the inner cover plate 6 of one of the columns 1. Then, push the second clamping block 31 into the placement slot 30 of the positioning rod 28, and adjust its position so that it can be smoothly inserted into the positioning slot 8 of the inner cover plate 6 of the other column 1. Then, push it in and fix it. Rotate the nut 34 so that it moves along the threaded rod 32 and drives the top ring 33 to closely contact the positioning rod 28, thereby firmly fixing the positioning rod 28. By holding the positioning rod 28 and applying force, the sliding blocks 3 in the two columns 1 are synchronously moved to the required height position. After that, rotate the third bolt 23 to push the wedge block 19 in the direction of the first top block 12 and the second top block 13. Since the first top block 12 and the second top block 13 are in contact with the inclined surface of the wedge block 19, they will be pushed and protrude from the mounting block 4 until they tightly press against the inner wall of the sliding slot 2, realizing the fixation of the sliding block 3. Finally, remove the positioning rod 28 to complete the positioning of the sliding block 3.
[0020] S2: Use the fourth bolt 25 to tightly connect the laminate 24 with the mounting plate 26. Align and snap the female buckle 27 on the mounting plate 26 with the male buckle 7 on the cover plate 6 to ensure a firm and reliable connection between the laminate 24 and the column 1.
[0021] S3: When it is necessary to adjust the height of the laminate 24, first remove the laminate 24, separate the female buckle 27 from the male buckle 7. Then, accurately insert the first clamping block 29 of the positioning rod 28 into the positioning slot 8 of the inner cover plate 6 of one of the columns 1. Then, push the second clamping block 31 into the placement slot 30 of the positioning rod 28, and adjust its position so that it can be smoothly inserted into the positioning slot 8 of the inner cover plate 6 of the other column 1. Then, push it in and fix it. Rotate the nut 34 so that it moves along the threaded rod 32 and drives the top ring 33 to closely contact the positioning rod 28, thereby firmly fixing the positioning rod 28. After that, reverse-rotate the third bolt 23 to release the pressure on the first top block 12 and the second top block 13. Under the action of the tension spring 17, the first top block 12 and the second top block 13 will move towards each other and retract into the mounting block 4, releasing the tight state against the inner wall of the sliding slot 2. By holding the positioning rod 28 and applying force, the sliding block 3 slides in the sliding slot 2 to a new height position. After that, rotate the third bolt 23 to push the wedge block 19 in the direction of the first top block 12 and the second top block 13. Since the first top block 12 and the second top block 13 are in contact with the inclined surface of the wedge block 19, they will be pushed and protrude from the mounting block 4 until they tightly press against the inner wall of the sliding slot 2, realizing the fixation of the sliding block 3. Finally, remove the positioning rod 28 to complete the positioning of the sliding block 3. Then, remove the positioning rod 28. Finally, align and snap the female buckle 27 on the mounting plate 26 with the male buckle 7 on the cover plate 6 to ensure a firm and reliable connection between the laminate 24 and the column 1.
