Description

Technical Field

[0001] The utility model relates to the technical field of density boards, in particular to a compression-resistant density board. Background Art

[0002] Density board is made of wood fiber or other plant fiber, which is prepared by fiber preparation, applied with synthetic resin, and pressed into a board under heating and pressure. Density board is widely used in making furniture, such as tables, cabinets, etc., but because density board is formed by pressing fiber fragments, its load-bearing capacity is poor, and it is easy to bend and break under the concentrated pressure of heavy objects, causing the items placed on the board to fall.

[0003] A Chinese patent with announcement number CN217968732U discloses a compression-resistant density board, comprising an upper plate body and a lower plate body, wherein a reinforcing strip assembly is convexly provided on the upper surface of the lower plate body, and a connecting groove is concavely provided on the lower surface of the upper plate body, and the connecting groove is cooperatively connected with the reinforcing strip assembly.

[0004] The compression-resistant density board described in the above patent is mainly used to improve the overall compression resistance of the density board by installing a reinforcing strip assembly between the upper and lower plate bodies. Although the installation of the reinforcing strip assembly can improve the compression resistance of the density board body, the reinforcing strip assembly in the compression-resistant density board of the above structure is designed as an integral whole with the lower plate body, and the upper and lower plate bodies are mainly fixed together by bonding and pressing. Not only does it make the assembly process of the compression-resistant density board of the above structure more complicated when in use, but it will also make the density board unable to be efficiently recycled due to the inconvenience of disassembling the reinforcing strip assembly when the density board is scrapped and recycled in the later stage.

[0009] Furthermore, the insertion hole is formed on the density board body, and the size of the insertion hole matches the size of the reinforcing rod.

[0010] By adopting the above technical solution, it can be ensured that the reinforcing rod can be easily inserted into the insertion hole, so as to increase the overall compressive strength of the density board body after the reinforcing rod is inserted.

[0011] Furthermore, the size of the receiving groove is larger than the size of the mounting plate, the push spring is welded to the mounting plate, and the reinforcing rod passes through the push spring.

[0012] By adopting the above technical solution, the push spring contacts the receiving groove at one end facing the receiving groove, and when the limit at the quick-release assembly is released, the mounting plate can be quickly ejected from the receiving groove under the action of the push spring.

[0013] Furthermore, the fixing portion of the spring rod is welded to the slide groove, and the telescopic portion of the spring rod is bolted to the shift block.

[0014] By adopting the above technical solution, the spring rod is mainly used to realize the sliding reset of the shift block along the sliding groove.

[0015] Furthermore, the shift block is slidably connected to the slide groove, and the insertion rod is welded to the shift block.

[0016] By adopting the above technical solution, convenient sliding adjustment of the shift block relative to the slide groove can be ensured.

[0017] Furthermore, the limiting hole does not penetrate through the side wall of the density board body, and the insertion rod matches the size of the limiting hole.

[0018] By adopting the above technical solution, the insertion rod cooperates with the limiting hole to ensure that the reinforcement frame is reliably installed and fixed on the density board body.

[0019] Furthermore, the insertion hole passes through the density board body, and the density board body is formed by pressing flame-retardant fiber scraps.

[0020] By adopting the above technical solution, the flame retardant performance of the density board body can be effectively ensured.

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] In order to solve the problem that the existing compression-resistant density board is mainly used to install a reinforcing strip assembly between the upper and lower plate bodies when in use, so that the overall compression resistance of the density board is improved. Although the installation of the reinforcing strip assembly can improve the compression resistance of the density board body, since the reinforcing strip assembly in the compression-resistant density board of the above structure is designed as an integral whole with the lower plate body, and the upper and lower plate bodies are mainly fixed together by bonding and pressing, not only the assembly process of the compression-resistant density board of the above structure is more cumbersome when in use, but also the density board cannot be efficiently recycled due to the inconvenience of disassembling the reinforcing strip assembly when the density board is scrapped and recycled in the later stage. The utility model provides a storage groove and a plug hole on the density board body, and installs a quick-release assembly and a push spring on the reinforcing frame, so that the assembly between the density board body and the reinforcing frame when in use is more efficient. At the same time, when the density board body is scrapped in the later stage, the quick-release assembly and the push spring can be used to achieve rapid separation of the reinforcing frame and the density board body, so that the efficient recycling of the density board body when it is scrapped in the later stage is convenient.
