Description

Technical Field

[0001] This utility model relates to the field of engineered wood products technology, specifically to a composite medium-density fiberboard. Background Technology

[0002] Medium-density fiberboard (MDF) is a type of engineered wood product made from wood fibers or other plant fibers, bonded with urea-formaldehyde resin or other synthetic resins, and pressed under heat and pressure. MDF possesses excellent physical and mechanical properties and processing characteristics, and can be manufactured in various thicknesses, making it widely used in furniture manufacturing, construction, and interior decoration. MDF is typically produced in pre-fabricated sheets of a specific size, which are then joined together using adhesives or splicing methods. While adhesives provide a tight bond, they are less convenient for disassembly and reassembly. Existing splicing and disassembly methods require bolts for fixing, making installation cumbersome. For example, Chinese utility model patent CN 215271544 U discloses a modular fiberboard. The fiberboard body has slots at both ends, a limiting groove on the side wall of the left slot, and a limiting protrusion fixedly connected to the side wall of the right slot. The left end of the fiberboard body has symmetrically arranged first threaded holes on both sides of the limiting groove, and the right end of the fiberboard body has symmetrically arranged second threaded holes on both sides of the limiting protrusion. Fixing bolts are threaded into the first and second threaded holes. Therefore, a simpler and more convenient modular fiberboard is needed. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a modular medium-density fiberboard that is easy to assemble and disassemble and is not prone to falling off.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a combined medium-density fiberboard (MDF) comprising a MDF body, wherein a connecting strip is protruding on one side of the MDF body and a connecting groove is provided on the other side to engage with the connecting strip; at least one first locking strip is provided on the upper surface of the connecting strip and at least one second locking strip is provided on the lower surface of the connecting strip; a first locking groove is provided on the upper surface of the connecting groove to match and connect with the first locking strip, and a second locking groove is provided on the lower surface of the connecting groove to match and connect with the second locking strip.

[0005] Preferably, the first card strip and the second card strip are symmetrically distributed.

[0006] Preferably, the first card strip and the second card strip are staggered.

[0007] Preferably, the number of the first card strips is greater than or equal to the number of the second card strips.

[0008] Preferably, the cross-section of the first card strip is a U-shaped structure.

[0009] Preferably, the connecting strip has a slot in the middle, and the connecting groove has an insert that matches the slot in the middle.

[0010] Preferably, the upper and lower surfaces of the medium-density fiberboard body are provided with a waterproof layer, and the medium-density fiberboard body is provided with a waterproof strip on one side of the connecting strip.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects:

[0012] This invention, by setting a first locking strip and a second locking strip on the upper and lower surfaces of the connector respectively, and cooperating with the first and second locking slots at the connecting groove, enables the quick insertion and combination of two plates, making installation more convenient, improving installation efficiency, and preventing the plates from falling off. Furthermore, the setting of the slots and inserts increases the interface contact area, further improving the connection stability and tightness, extending the interface path, preventing moisture from penetrating through the connection part, and ensuring installation quality.

[0020] Example 1

[0021] like Figure 1 As shown, a composite medium-density fiberboard (MDF) includes an MDF body 1. A connecting strip 3 protrudes from one side of the MDF body 1, and a connecting groove 4 on the other side engages with the connecting strip 3. A first retaining strip 31 is provided on the upper surface of the connecting strip 3, and a second retaining strip 32 is provided on the lower surface of the connecting strip 3. A first retaining groove 41 corresponding to the first retaining strip 31 is provided on the upper surface of the connecting groove 4, and a second retaining groove 42 corresponding to the second retaining strip 32 is provided on the lower surface of the connecting groove 4. The number of first retaining strips 31 and second retaining strips 32 is equal. The first retaining strips 31 and second retaining strips 32 are symmetrically distributed. A slot 9 is provided in the middle of the connecting strip 3, and an insert matching the slot 9 is provided in the middle of the connecting groove 4. The depth of the slot 9 is equal to the width of the connecting strip 3. By providing the slot 9, the contact area of ​​the connecting end is increased, further improving the tightness of the connection, extending the interface path, preventing moisture penetration through the connection, and ensuring installation quality.

[0022] The upper and lower surfaces of the medium-density fiberboard (MDF) body 1 are provided with a waterproof layer 2, and a waterproof strip 5 is provided on one side of the MDF body 1 located at the connecting strip 3. By setting the waterproof layer 2, the waterproof performance of the MDF body 1 is improved, preventing moisture penetration that could cause board deformation and reduce service life. By setting the waterproof strip 5 at the joint, the waterproof performance of the interface gap is enhanced, preventing water from seeping in through the interface gap and causing board deformation.

[0023] When connecting two adjacent medium-density fiberboard (MDF) bodies 1, the connecting strip 3 is inserted into the connecting groove 4 from one end, aligning the first locking strip 31 with the first locking groove 41 and the second locking strip 32 with the second locking groove 42, quickly completing the alignment and splicing of the two. Because the connecting strips are provided on the upper and lower surfaces, the tightness of the connection is improved, and the two MDF bodies 1 are less likely to detach after assembly, making installation more convenient and improving installation efficiency.

[0024] Example 2

[0025] Unlike Example 2, as Figure 2 As shown, the first card strip 31 and the second card strip 32 are misaligned.

[0026] Example 3

[0027] like Figure 3 As shown, unlike Embodiment 1, the upper surface of the connecting strip 3 is provided with two first retaining strips 31, and the lower surface of the connecting strip 3 is provided with two second retaining strips 32. The upper surface of the connecting groove 4 is provided with two first retaining grooves 41 that match and connect with the first retaining strips 31, and the lower surface of the connecting groove 4 is provided with two second retaining grooves 42 that match and connect with the second retaining strips 32. The cross-section of the first retaining strips 31 is a U-shaped structure. Because multiple serrated portions are formed at the joint ends of the plates, the tightness of the connection is enhanced, and the waterproof performance at the joint is improved, further preventing moisture from penetrating through the joint.

[0028] Example 4

[0029] Unlike embodiment 4, the upper surface of the connecting strip 3 is provided with three first retaining strips 31, and the lower surface of the connecting strip 3 is provided with one second retaining strip 32. The upper surface of the connecting groove 4 is provided with three first retaining grooves 41 that match and connect with the first retaining strips 31, and the lower surface of the connecting groove 4 is provided with one second retaining groove 42 that matches and connects with the second retaining strip 32. Because multiple tooth-like portions are formed at the joint ends of the plates, the tightness of the connection is enhanced, and the waterproof performance at the joint is improved, further preventing moisture from penetrating through the joint.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
