Description

Technical Field

[0001] The utility model relates to the technical field of plywood, in particular to an easy-to-assemble plywood structure. Background Art

[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them together with adhesive. It is usually made of an odd number of veneers, with the fibers of adjacent layers glued perpendicular to each other. It is one of the commonly used materials for furniture and one of the three major types of man-made boards. It can also be used as material for airplanes, ships, trains, cars, buildings, and packaging boxes.

[0003] However, when assembling existing plywood, workers need to align the two plywood sheets first, and then use tools to drive nails into the inside of the plywood sheets to achieve the purpose of assembly and splicing. The operation steps are cumbersome and affect the assembly and splicing efficiency of the plywood sheets. At the same time, the nails will damage the plywood sheets when they come into contact with the plywood sheets. When the plywood sheets are disassembled, the nails need to be removed, and hole marks will be left on the plywood sheets, which has a certain impact on the service life of the plywood sheets. Therefore, an easy-to-assemble plywood structure is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide an easy-to-assemble plywood structure. The utility model solves the problem of the inconvenience of assembling and splicing plywood A and plywood B when using existing plywood by arranging a limiting rod, a fixing block, a groove, a limiting hole, a driving rod, a spring and a threaded block.

[0005] The technical solution adopted by the utility model to solve its technical problems is an easy-to-assemble plywood structure, comprising plywood A and plywood B, wherein a fixing block connected to plywood B is inserted on the outside of plywood A, a groove is provided on the surface of plywood B for allowing the fixing block to enter the interior of plywood B, a driving rod is inserted on one side of plywood B, and a threaded block is threadedly connected to one end of the driving rod for driving the driving rod to move, a limiting rod for limiting the fixing block is welded on the outside of the driving rod, a limiting hole is provided on the surface of the fixing block for allowing the limiting rod to enter the interior of the fixing block, a spring for resetting the limiting rod is welded on one side of the limiting rod, and the interior of the plywood A comprises a flame retardant layer A, a flame retardant layer B, a sound insulation layer and a thermal insulation layer.

[0006] By adopting the above technical solution, when plywood A and plywood B are to be spliced, the threaded block outside plywood B is first pulled, and then the threaded block drives the driving rod to move, and the driving rod drives the limiting rod to move out of the groove, and the spring outside the limiting rod is compressed, and then the fixing block on one side of plywood A is placed in the groove opened on the surface of plywood B, and then the pulling force on the threaded block is removed, and then the spring drives the limiting rod to pop out outward, and then the limiting rod enters the limiting hole opened on the surface of the fixing block, and the driving rod enters the inside of plywood B, thereby facilitating the assembly and splicing of plywood A and plywood B.

[0007] Specifically, the plywood A is bonded with a flame retardant layer A and a flame retardant layer B to increase the flame retardant performance of the plywood A, a sound insulation layer is bonded to one side of the flame retardant layer B to improve the sound insulation performance of the plywood A, and a thermal insulation layer is bonded to the side of the sound insulation layer away from the flame retardant layer B.

[0008] By adopting the above technical solution, the flame retardant layer A in the plywood A is made of a phenolic foam fireproof insulation board and has good flame retardant properties. The flame retardant layer B on one side of the flame retardant layer A is made of a polystyrene resin and has high flame retardant properties, which can effectively reduce the risk of fire. The sound insulation layer of the flame retardant layer B is made of sound insulation cotton to absorb external noise. The insulation layer on one side of the sound insulation layer is made of glass fiber and has low thermal conductivity. At the same time, the flame retardant layer A made of a phenolic foam fireproof insulation board and the flame retardant layer B made of a polystyrene resin have good thermal insulation properties, thereby improving the flame retardant and thermal insulation properties of the plywood A.

[0009] Specifically, a support rod is fixedly installed inside the plywood B, and a support sleeve connected to the driving rod is slidably connected outside the support rod.

[0010] By adopting the above technical solution, when the driving rod moves in the plywood B, the support sleeve fixed by the outer screw of the driving rod slides outside the support rod, thereby preventing the driving rod from deflecting and improving the stability of the driving rod movement.

[0011] Specifically, one end of the driving rod is provided with a thread groove connected to the thread block.

[0012] By adopting the above technical solution, after plywood A and plywood B are assembled and spliced, the threaded block is moved by rotating the driving rod, and then the threaded block is removed from the threaded groove opened on the surface of the driving rod, thereby improving the flatness of the outside of plywood B.

[0013] Specifically, a rubber sleeve for increasing surface friction is bonded to the outer side of the threaded block.

[0014] By adopting the above technical solution, when the threaded block drives the driving rod to move, the rubber sleeve outside the threaded block increases the friction force on the surface of the threaded block, making it easier for the threaded block to drive the driving rod to move.

[0015] Beneficial effects of the utility model:

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] In order to assemble and splice the plywood A1 and the plywood B2, as an embodiment of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, the utility model describes an easy-to-assemble plywood structure, comprising plywood A1 and plywood B2, wherein the plywood A1 is externally plugged with a fixing block 4 connected to the plywood B2, and the surface of the plywood B2 is provided with a groove 6 for allowing the fixing block 4 to enter the interior of the plywood B2, a driving rod 8 is plugged into one side of the plywood B2, and one end of the driving rod 8 is threadedly connected to a threaded block 11 for driving the driving rod 8 to move, a limiting rod 7 for limiting the fixing block 4 is welded to the outside of the driving rod 8, a limiting hole 5 for allowing the limiting rod 7 to enter the interior of the fixing block 4 is provided on the surface of the fixing block 4, and a spring 10 for resetting the limiting rod 7 is welded to one side of the limiting rod 7, and the interior of the plywood A1 comprises a flame retardant layer A13, a flame retardant layer B14, a sound insulation layer 15 and a thermal insulation layer 16.

[0027] During use, when plywood A1 and plywood B2 are to be spliced, first pull the threaded block 11 outside plywood B2, and then the threaded block 11 drives the driving rod 8 to move, and the driving rod 8 drives the limiting rod 7 to move out of the groove 6, and the spring 10 outside the limiting rod 7 is compressed, and then the fixing block 4 on one side of the plywood A1 is placed in the groove 6 opened on the surface of the plywood B2, and then the pulling force on the threaded block 11 is removed, and then the spring 10 drives the limiting rod 7 to pop out outward, and then the limiting rod 7 enters the limiting hole 5 opened on the surface of the fixing block 4, and the driving rod 8 enters the inside of the plywood B2, thereby facilitating the assembly and splicing of plywood A1 and plywood B2.

[0028] In order to improve the flame retardant and heat-insulating properties of the plywood A1, for example, Figure 5 As shown, the present invention also includes that the plywood A1 is internally bonded with a flame retardant layer A13 and a flame retardant layer B14 for increasing the flame retardant performance of the plywood A1, one side of the flame retardant layer B14 is bonded with a sound insulation layer 15 for improving the sound insulation performance of the plywood A1, and the side of the sound insulation layer 15 away from the flame retardant layer B14 is bonded with a thermal insulation layer 16.

[0029] When in use, the flame retardant layer A13 in the plywood A1 is made of a phenolic foam fireproof insulation board and has good flame retardant properties. The flame retardant layer B14 on one side of the flame retardant layer A13 is made of a polystyrene resin and has high flame retardant properties, which can effectively reduce the risk of fire. The sound insulation layer 15 on the first layer of the flame retardant layer B14 is made of sound insulation cotton to absorb external noise. The thermal insulation layer 16 on one side of the sound insulation layer 15 is made of glass fiber and has low thermal conductivity. At the same time, the flame retardant layer A13 made of a phenolic foam fireproof insulation board and the flame retardant layer B14 made of a polystyrene resin have good thermal insulation properties, thereby improving the flame retardant and thermal insulation properties of the plywood A1.

[0030] In order to improve the stability of the movement of the driving rod 8, for example, Figure 3 As shown, the present invention further includes that a support rod 17 is fixedly installed inside the plywood B2, and a support sleeve 9 connected to the driving rod 8 is slidably connected to the outside of the support rod 17.

[0031] During use, when the driving rod 8 moves in the plywood B2, the support sleeve 9 fixed with the outer screw of the driving rod 8 slides outside the support rod 17, preventing the driving rod 8 from deflecting and improving the stability of the movement of the driving rod 8.

[0032] In order to improve the flatness of the outer surface of the plywood B2, for example, Figure 4 As shown, the present invention further includes that one end of the driving rod 8 is provided with a thread groove 12 connected to the thread block 11.

[0033] During use, after plywood A1 and plywood B2 are assembled and spliced, the threaded block 11 is moved by rotating the driving rod 8, and then the threaded block 11 is removed from the threaded groove 12 opened on the surface of the driving rod 8, thereby improving the flatness of the outside of the plywood B2.

[0034] In order to facilitate the threaded block 11 to drive the driving rod 8 to move, for example, Figure 1 As shown, the present invention further includes a rubber sleeve 3 bonded to the outer side of the threaded block 11 to increase surface friction.

[0035] During use, when the threaded block 11 drives the driving rod 8 to move, the rubber sleeve 3 outside the threaded block 11 increases the friction force on the surface of the threaded block 11, making it easier for the threaded block 11 to drive the driving rod 8 to move.

[0036] When the utility model is in use, when the plywood A1 and the plywood B2 are to be spliced ​​together, the threaded block 11 on the outside of the plywood B2 is first pulled, and then the threaded block 11 drives the driving rod 8 to move, and the driving rod 8 drives the limiting rod 7 to move out of the groove 6, and the spring 10 outside the limiting rod 7 is compressed, and then the fixing block 4 on one side of the plywood A1 is placed into the groove 6 opened on the surface of the plywood B2, and then the pulling force on the threaded block 11 is removed, and then the spring 10 drives the limiting rod 7 to pop outward, and then the limiting rod 7 enters the limiting hole 5 opened on the surface of the fixing block 4, and the driving rod 8 enters the interior of the plywood B2, thereby facilitating the assembly and splicing of the plywood A1 and the plywood B2;

[0037] The flame retardant layer A13 within the plywood A1 is made of a phenolic foam fireproof insulation board and has excellent flame retardant properties. The flame retardant layer B14 on one side of the flame retardant layer A13 is made of a polystyrene resin and has high flame retardant properties, which can effectively reduce the risk of fire. The sound insulation layer 15 on the flame retardant layer B14 is made of sound insulation cotton to absorb external noise. The thermal insulation layer 16 on one side of the sound insulation layer 15 is made of glass fiber and has low thermal conductivity. At the same time, the flame retardant layer A13 made of the phenolic foam fireproof insulation board and the flame retardant layer B14 made of the polystyrene resin have excellent thermal insulation properties, thereby improving the flame retardant and thermal insulation properties of the plywood A1.

[0038] When the driving rod 8 moves in the plywood B2, the support sleeve 9 fixed with the screw outside the driving rod 8 slides outside the support rod 17, preventing the driving rod 8 from deflecting and improving the stability of the movement of the driving rod 8;

[0039] After plywood A1 and plywood B2 are assembled and spliced, the threaded block 11 is moved by rotating the driving rod 8, and then the threaded block 11 is moved out of the threaded groove 12 opened on the surface of the driving rod 8, thereby improving the flatness of the outer surface of plywood B2;

[0040] When the threaded block 11 drives the driving rod 8 to move, the rubber sleeve 3 outside the threaded block 11 increases the friction force on the surface of the threaded block 11, making it easier for the threaded block 11 to drive the driving rod 8 to move.
