Description

Technical Field

[0001] The utility model relates to the technical field of multi-layer boards, in particular to a multi-layer board that is convenient to disassemble. Background Technique

[0002] A multi-layer board is a board made by gluing multiple thin wood boards. The grain directions of each layer of wood board are cross-laminated and glued under high temperature and high pressure. A multi-layer board is composed of at least three thin wood boards, usually an odd number of layers, such as 3 layers, 5 layers, 7 layers. The fiber direction of the middle layer of wood board is generally perpendicular to the length or width direction of the board, which is called cross-laminated gluing. This can improve the strength and stability of the board. A multi-layer board that is convenient to disassemble usually refers to those boards that can be easily disassembled or moved when needed. This characteristic is very practical for some occasions that require frequent changes or movements. Multi-layer boards that are convenient to disassemble are usually widely used in exhibitions, temporary structures, prefabricated buildings, and short-term use occasions. Their design and use flexibility make them an ideal choice for many projects.

[0003] However, most multi-layer boards are usually fixed with bolts during use. During use, it may be that when installing, the bolts are driven too deep, resulting in the board breaking or cracking, or after installation, the bolts are bent, or rain erosion causes the bolts to rust, resulting in the problem of being unable to disassemble and replace or difficult to replace.

[0025] Specifically, the A plate 1 and the B plate 3 are connected under the limitation of the positioning rod 2 and the positioning groove 4. At this time, the fixed insertion plate 5 slides into the inner wall of the sleeve 13. By pressing the first pressing rod 6, the inclined rod 9 and the first spring 7 are driven to compress downward. During the movement of the inclined rod 9, the inclined surface of the inclined rod 9 drives the ejector rod 10 to compress the second spring 12 inside the fixed insertion plate 5. The protruding point of the ejector rod 10 drives the clamping block 11 to be stuck on the inner wall of the clamping groove 14, achieving the effect of quick fixation during use. By driving the clamping plate 8 to slide out from the inner wall of the fixed insertion plate 5 through the disengaging rod 21, and driving the ejector rod 10 to eject outward through the second spring 12, it achieves the effect of quickly releasing the clamping block 11 from the inner wall of the clamping groove 14 during use, and also achieves the effect of quickly disassembling and replacing the multilayer board and disassembling during use.

[0026] Refer to Figure 1 and Figure 4 , the other end of the first spring 7 is fixedly connected to the inner wall of the fixed insertion plate 5. The outer wall of the ejector rod 10 is slidably connected to the inner wall of the fixed insertion plate 5. The outer wall of the clamping block 11 is slidably connected to the inner wall of the clamping groove 14; Insertion rods 19 are fixedly connected to the inner walls of the A plate 1 and the B plate 3, and the clamping grooves 14 are slidably connected to the lower surfaces of the A plate 1 and the B plate 3; A threaded rod 15 is threadedly connected to the inner wall of the clamping groove 14, and a clamping rod 16 is fixedly connected to the upper surface of the threaded rod 15;

[0027] Specifically, the first spring 7 ejects the fixed insertion plate 5 outward, achieving the effect of quick disassembly during use. Through the insertion rods 19 below the A plate 1 and the B plate 3, when the clamping rod 16 slides into the inner wall of the insertion rod 19, it achieves the effect of quickly installing and using the A plate 1 and the B plate 3.

[0028] Refer to Figure 4 , a fixed round head 20 is fixedly connected to the top end of the clamping rod 16, and the outer wall of the fixed round head 20 is slidably connected to a fixed sleeve 17; The outer wall of the clamping rod 16 is slidably connected to the inner wall of the insertion rod 19, and the outer wall of the fixed sleeve 17 is slidably connected to an anti - detachment ring 18; The outer wall of the anti - detachment ring 18 is fixedly connected to the bottom inner wall of the insertion rod 19;

[0029] Specifically, the clamping rod 16 drives the fixed round head 20 to insert into the inner wall of the fixed sleeve 17. During use, the anti - detachment ring 18 fixes the fixed sleeve 17 to prevent it from falling off. When the fixed round head 20 inserts into the inside of the fixed sleeve 17, the anti - detachment ring 18 plays a role in preventing it from falling off, achieving the effect of quick fixation during use.

[0030] Working principle: When the multi-layer board needs to be used, the A board 1 and the B board 3 are connected under the limitation of the positioning rod 2 and the positioning groove 4. At this time, the fixed plug board 5 slides into the inner wall of the sleeve 13. By pressing the first pressing rod 6, the inclined rod 9 and the first spring 7 are compressed downward. During the movement of the inclined rod 9, the inclined surface of the inclined rod 9 drives the ejector rod 10 to compress the second spring 12 inside the fixed plug board 5. The protruding point of the ejector rod 10 drives the clamping block 11 to be stuck inside the clamping groove 14, which plays the role of quickly installing and fixing the fixed plug board 5 and the A board 1 during use. During use, the positioning rod 2 and the positioning groove 4 are further used to increase the effect of preventing deviation and falling off when the A board 1 and the B board 3 are connected. The positioning rod 2 can make the connection between the A board 1 and the B board 3 more stable, preventing the A board 1 and the B board 3 from separating. By driving the clamping board 8 to move on the inclined surface of the separating rod 21 through the separating rod 21, the clamping board 8 slides out from the inner wall of the fixed plug board 5. The first spring 7 pops the inclined rod 9 outwards, and the second spring 12 drives the ejector rod 10 to pop outwards, which plays the role of quick detachment during use. During use, the plug rod 19 driven by the B board 3 and the A board 1 clamps the fixed round head 20 into the inner walls of the fixed sleeve 17 and the anti-detachment ring 18. During use, the anti-detachment ring 18 can prevent the fixed round head 20 and the clamping rod 16 from falling off, thus playing the role of quickly installing and using the A board 1 and the B board 3 during use. During use, the multi-layer board not only has the effect of quickly detaching by driving the clamping board 8 to slide out from the inner wall of the fixed plug board 5 through the separating rod 21 and ejecting the ejector rod 10 by the second spring 12, but also has the effect of fixing the fixed round head 20 through the fixed sleeve 17 and the anti-detachment ring 18, playing the role of quickly installing and using the A board 1 and the B board 3 during use.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
