[0002] With the acceleration of urbanization, the demand for small apartments, multi-functional spaces, and other living spaces has surged. Traditional fixed sofa armrests take up a lot of space and cannot meet the need for flexible space utilization. Therefore, the market demand for sofa armrests with folding functions is becoming increasingly urgent. However, existing folding sofa armrests mostly use multi-stage hinges and manual locking combinations, which have many parts and high assembly costs. Moreover, folding requires a step-by-step operation of unlocking, folding, and locking, resulting in a poor user experience. In addition, existing sofas cannot hold mobile phones, water cups, or other items on the armrests, and users need to get up from the coffee table to retrieve them, which is not comfortable. To solve the above problems, a quick folding and positioning device for sofa armrests is needed.

[0003] The existing sofa armrest quick folding and positioning device has the problem that it cannot stably hold items on the sofa armrest and is inconvenient to fold and position the sofa armrest. Therefore, there is an urgent need for a sofa armrest quick folding and positioning device. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a quick-folding and positioning device for sofa armrests, so as to solve the problems that existing sofa armrests cannot stably hold items on them and are inconvenient to fold and position.

[0006] Preferably, when the armrest is placed horizontally, its outer wall is in close contact with the support plate, and the armrest forms a rotating structure with the sofa seat through a pivot.

[0007] Preferably, the lever is telescopically connected to the armrest via a limiting spring, and the lever is engaged with the sofa seat.

[0008] Preferably, the serving tray forms a flipping structure through a rotating rod and a positioning rod, and the serving tray is symmetrically arranged with the central axis of the sofa seat as the center.

[0009] Preferably, the serving plate is tightly fitted to the outer wall of the handrail, and the serving plate is magnetically fixed to the handrail by a magnetic block.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model uses a support plate, armrest, pivot, limiting spring, and locking rod. The locking rod is pulled inward, and then the horizontal armrest is rotated around the pivot to stand upright. Then the locking rod is released, and the locking rod is pushed out by the elastic force of the limiting spring, so that the locking rod is locked and fixed to the sofa seat. This achieves quick folding and positioning of the armrest. The support plate provides support for the armrest when it is horizontal, preventing excessive folding and affecting its use.

[0012] 2. This utility model, through the setting of magnetic blocks, positioning rods, rotating rods, and a storage plate, allows the storage plate to be flipped by the rotating rod when the armrest is upright, making the storage plate fit against the top of the armrest. At this time, the storage plate is magnetically fixed to the armrest by the magnetic blocks. Snacks, drinks, mobile phones, and other items can then be placed on the storage plate. You can watch TV while using the items placed on it without having to get up to get them from the coffee table, making it more convenient and comfortable to use. Attached Figure Description
