Description

Technical Field

[0001] The utility model relates to the technical field of sofas, in particular to a sofa with detachable armrests. Background Art

[0002] A sofa is a type of soft furniture, which is a multi-seat chair with soft cushions and armrests on both sides. The frame is made of wood or steel lined with cotton wool and other foam materials, and is comfortable overall. In order to facilitate transportation, the armrests of sofas are generally designed to be detachable. However, when disassembling the armrests of sofas, tools such as screwdrivers and wrenches are generally required, which results in a long time spent on disassembly of the armrests. The subsequent installation of the armrests also requires the use of tools, which is more troublesome. Therefore, a sofa with detachable armrests is proposed to facilitate the disassembly and assembly of the armrests. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a sofa with detachable armrests.

[0005] By adopting the above technical solution, the cover is rotated, and the hand is put into the box body to push the two card blocks toward each other, and the ends of the two card blocks are disengaged from the card slots on both sides of the base. The box body is pushed away from the base to make the plug block disengage from the slot on one side of the base, which is convenient for the disassembly of the handrail. During installation, the two card blocks are pushed toward each other, the plug block is inserted into the slot on one side of the base and then the two card blocks are released. During the resetting process of the two springs, the two card blocks are pushed to move away from each other, and the ends of the two card blocks are inserted into the two card slots on one side of the base, which is convenient for the installation of the handrail.

[0006] Specifically, guide rods are fixed to the side walls of the two clamping blocks facing each other, and two grooves for the guide rods to move horizontally are arranged in the inserting block.

[0007] By adopting the above technical solution, the guide rod cooperates with the groove in the insert block, which can improve the stability of the block.

[0008] Specifically, a partition is fixed in the box.

[0009] By adopting the above technical solution, the partition can divide the space inside the box, making it convenient to store items.

[0010] Specifically, a vertical plate is provided on the side of the partition away from the plug-in block, and a plurality of slots adapted to the vertical plate are provided on the side of the partition away from the plug-in block and on the vertical inner wall of the box body.

[0011] By adopting the above technical solution, the vertical plates are inserted into the slots at different positions of the partition side walls, so that the space inside the box can be further divided, which is conducive to the classified storage of items.

[0012] Specifically, a groove for inserting fingers is provided on a side of the cover plate away from the backrest.

[0013] By adopting the above technical solution, a finger is inserted into the groove on one side of the cover plate to facilitate lifting the cover plate away from the side of the backrest.

[0014] Beneficial effects of the utility model:

[0015] (1) The utility model discloses a sofa with detachable armrests. The cover plate is rotated, and a hand is put into the box body to push the two card blocks toward each other. The ends of the two card blocks are disengaged from the card slots on both sides of the base.
