Description

Technical Field

[0001] The utility model relates to a plywood, in particular to a firmly connected plywood, belonging to the technical field of plywood. 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. Usually an odd number of layers of veneer are used. 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] At present, plywood is often directly glued between single boards during manufacturing. Due to uneven application of glue, or the environment in which the plywood is used is too humid or dry, or excessive climate change, the plywood can easily crack, making the connection between the plywood layers loose and tight, causing the plywood to detach, affecting the structural strength and service life of the plywood.

[0004] Therefore, it is urgent to improve to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides an embodiment of a firmly connected plywood.

[0024] A firmly connected plywood comprises an upper plywood 1 and a lower plywood 2, wherein a fixing structure 3 is arranged on the upper plywood 1 and the lower plywood 2, wherein the fixing structure 3 comprises two fixing side panels 4 installed on both sides of the upper plywood 1 and the lower plywood 2, wherein a plurality of grooves 5 are provided on the upper plywood 1 and the lower plywood 2, wherein two springs 6 are symmetrically fixedly installed inside the grooves 5, wherein a clamping rod 7 is fixedly installed at one end of the spring 6, and two clamping blocks 8 which are engaged with the clamping rod 7 are fixedly installed on the inner wall of the fixing side panel 4. The fixing structure 3 is provided to replace the glue bonding method to connect the plywood layers. When the upper plywood 1 and the lower plywood 2 are connected and installed, the upper plywood 1 and the lower plywood 2 are bonded first, and then the two fixed side panels 4 are butted against the two sides of the upper plywood 1 and the lower plywood 2. After the two fixed side panels 4 are bonded with the upper plywood 1 and the lower plywood 2, the clamping blocks 8 on the fixed side panels 4 extend into the grooves 5 provided on the upper plywood 1 and the lower plywood 2, and the clamping rods 7 in the grooves 5 are engaged with the clamping blocks 8 under the action of the springs 6. Under the action of the engagement, the upper plywood 1 and the lower plywood 2 are connected and assembled by the docking of the two fixed side panels 4. The engagement method is more firm and tight than the traditional glue bonding method, and can effectively prevent the upper plywood 1 and the lower plywood 2 from being separated, thereby improving its structural strength and service life.

[0025] One end of the clamping rod 7 is set to be conical, and multiple sealing grooves 9 are provided on the surfaces of the upper plywood 1 and the lower plywood 2. Multiple sealing blocks 10 that are sealed with the sealing grooves 9 are fixedly installed on the fixed side panel 4. Both ends of the fixed side panel 4 are provided with mounting grooves 11, and corner guards 12 are installed on the mounting grooves 11. The corners of the corner guards 12 are set to be arc-shaped. By setting one end of the clamping rod 7 to a cone, the clamping rod 7 and the clamping block 8 are easier to engage with each other, and it is also convenient to separate the clamping block 8 from the clamping rod 7, so that the fixed side panel 4 can be conveniently disassembled. By setting the sealing groove 9 and the sealing block 10, the connection between the fixed side panel 4 and the upper plywood 1 and the lower plywood 2 can be sealed to prevent dust, impurities and water vapor from entering the interior through the gap at the connection. By setting the installation groove 11 and the corner guard 12 and setting the corner of the corner guard 12 to an arc shape, the sharpness of the corner of the fixed side panel 4 can be reduced to avoid scratches on the human body at the corner during manufacturing or use.

[0026] The mounting groove 11 is provided with a first magnetic block 13 embedded in the fixed side panel 4, and the inner wall of the corner panel 12 is provided with a second magnetic block 14 adsorbed with the first magnetic block 13. The surfaces of the upper plywood 1 and the lower plywood 2 are provided with waterproof panels 15 connected by adhesive, and the surface of the fixed side panel 4 is provided with a wear-resistant coating 16. Through the provision of the first magnetic block 13 and the second magnetic block 14, the corner panel 12 can not only be fixed and prevented from falling off by the adsorption of the first magnetic block 13 and the second magnetic block 14, but also can be disassembled and replaced when the corner panel 12 is damaged. Through the provision of the waterproof panel 15, the waterproofness of the surface of the upper plywood 1 and the lower plywood 2 can be increased to prevent moisture penetration from damaging the structure of the upper plywood 1 and the lower plywood 2 and affecting its use. By applying a layer of wear-resistant coating 16 on the surface of the fixed side panel 4, the surface of the fixed side panel 4 is made more wear-resistant under the action of the wear-resistant coating 16, further improving its service life.

[0027] In this embodiment, if Figure 1-Figure 4 As shown, the working process of a firmly connected plywood provided in this embodiment is as follows:

[0028] When connecting and installing the upper plywood 1 and the lower plywood 2, first fit the upper plywood 1 and the lower plywood 2 together, and then dock the two fixed side panels 4 on both sides of the upper plywood 1 and the lower plywood 2. After the two fixed side panels 4 are fitted with the upper plywood 1 and the lower plywood 2, the clamping blocks 8 on the fixed side panels 4 extend into the grooves 5 provided on the upper plywood 1 and the lower plywood 2, and the clamping rods 7 in the grooves 5 are engaged with the clamping blocks 8 under the action of the springs 6. Under the action of the engagement, the upper plywood 1 and the lower plywood 2 are connected and assembled by docking the two fixed side panels 4. The engagement method is more firm and tight than the traditional glue bonding method, and can effectively prevent the upper plywood 1 and the lower plywood 2 from being separated, thereby improving its structural strength and service life.

[0029] In summary, in the present embodiment, according to a firmly connected plywood of the present embodiment, by setting one end of the clamping rod 7 to a cone, the clamping rod 7 and the clamping block 8 are easier to engage with each other, and it is also convenient to separate the clamping block 8 from the clamping rod 7, so as to facilitate the disassembly of the fixed side panel 4. By setting the sealing groove 9 and the sealing block 10, the connection between the fixed side panel 4 and the upper plywood 1 and the lower plywood 2 can be sealed to prevent dust, impurities and water vapor from extending into the interior through the gap at the connection. By setting the installation groove 11 and the corner guard 12 and setting the corner of the corner guard 12 to an arc shape, the sharpness of the corner of the fixed side panel 4 can be reduced to avoid the occurrence of problems during manufacturing or use. In the process, the corners may cause scratches to the human body. Through the arrangement of the first magnetic block 13 and the second magnetic block 14, the adsorption of the first magnetic block 13 and the second magnetic block 14 can not only fix the corner guard 12 and prevent it from falling off, but also can disassemble and replace the corner guard 12 when it is damaged. Through the arrangement of the waterproof plate 15, the waterproof property of the surface of the upper plywood 1 and the lower plywood 2 can be increased to avoid moisture penetration and damage to the structure of the upper plywood 1 and the lower plywood 2 affecting their use. By applying a layer of wear-resistant coating 16 on the surface of the fixed side panel 4, the surface of the fixed side panel 4 is made more wear-resistant under the action of the wear-resistant coating 16, further improving its service life.
