[0038] Generally, the armrest of a chair is integrally connected and fixed to the chair frame. However, for an armrest with more functions, the armrest is movably arranged on the seat. For example, a rotating and / or sliding structure is arranged between the armrest and the chair frame. In the related art, an adapter is arranged between the armrest and the chair frame, and the armrest is connected to the chair frame through the adapter. For example, a rotating structure is arranged between the adapter, the armrest, and the chair frame. The rotating structures of the armrest, the chair frame, and the adapter are respectively arranged at the two ends of the adapter. However, the existing adapters are mostly made of a single plastic material, and the overall rigidity of the adapter is poor, and the support for the armrest is poor. During long-term use, the adapter undergoes plastic bending deformation, causing the position of the armrest to gradually deviate from the initial design position, reducing the user experience.

[0039] For this reason, Figures 1 to 4 As shown, an aluminum-plastic combined handrail adapter assembly proposed by the utility model includes an aluminum frame 100 with a spatial bending structure, a first plastic block 200 installed on the aluminum frame 100, and a second plastic block 300 installed on the aluminum frame 100. It should be noted that the aluminum frame 100 is made of metal aluminum, such as aluminum alloy material; the first plastic block 200 and the second plastic block 300 are both made of plastic material, such as hard plastic material. Therefore, there are differences in the structural rigidity and material of the two different materials themselves. Specifically, the first concave 110 and the second concave 120 are respectively provided on both sides of the aluminum frame 100, and the first concave 110 and the second concave 120 are arranged at intervals along the length direction of the aluminum frame 100. Correspondingly, the first plastic block 200 is installed on one side of the aluminum frame 100, and the second plastic block 300 is installed on the other side of the aluminum frame 100. Furthermore, the first plastic block 200 includes a first convex portion 210, which is fitted in the first concave 110 to fill the first concave 110; the second plastic block 300 includes a second convex portion 310, which is fitted in the second concave 120 to fill the second concave 120; the whole forms a block that looks relatively solid. In application, the first plastic block 200 is used to connect with at least one of the chair frame and the armrest body 500. For example, the first plastic block is connected to the seat through a support, and the second plastic block is used to connect with the armrest body. In application, the first plastic block is movably connected to the seat, and the second plastic block is movably connected to the armrest body (not shown in the figure). At this time, they can be replaced as needed according to different wear conditions caused by different frequencies during use, saving costs. In some embodiments of the utility model, one side of the first plastic block 200 is connected to the seat through a support 600, and the other side is connected to the armrest body 500. As Figures 2 to 4As shown, the first plastic block 200 is provided with a positioning column 220, and the second plastic block 300 is provided with a positioning hole 302. The positioning column 220 is plugged and matched with the positioning hole 302, and the connection is stable. In addition, the positioning column 220 extends out of the second plastic block 300 and is used to connect with the armrest body 500. Further, the first convex portion 210 is connected to the chair frame through a support 600. It should be noted that the aluminum frame 100 can play a role in supporting and fixing the shape of the first plastic block 200, improve the stability of the first plastic block 200 and the chair frame or the armrest body 500 when installed and used, thereby reducing the amount of bending deformation and maintaining the consistency of the position of the armrest body 500 after long-term use. In addition, the aluminum frame 100 is a spatial bending structure, which effectively reduces the amount of material used and the overall structure is lighter. In addition, the second plastic block 300 fills the aluminum frame 100, and cooperates with the first plastic block 200, so that the shape design is more unique, the texture changes brought by different materials are obvious, and the aesthetics are better.

[0040] In some embodiments of the present invention, Figure 2 As shown, the peripheral walls of the aluminum frame 100 all have a rounded structure, the peripheral walls are smooth, and there are no obvious sharp angles, which reduces the risk of collision and scratching of users and improves the safety of users. Further, along the length direction of the aluminum frame 100, the width between the outer side walls of the aluminum frame 100 changes gradually, the curve change degree is high, and the shape is more unique. For example, along the length direction of the aluminum frame 100, the width between the outer side walls of the aluminum frame 100 gradually increases; for another example, along the length direction of the aluminum frame 100, the width between the outer side walls of the aluminum frame 100 gradually decreases; for another example, along the length direction of the aluminum frame 100, the width between the outer side walls of the aluminum frame 100 first gradually decreases and then gradually increases. In addition, the gradual setting can increase the structural rigidity of the aluminum frame 100 to a certain extent. For example, the width of the aluminum frame 100 toward the connection with the support 600 is larger, and the width of the aluminum frame 100 toward the connection with the armrest body 500 is relatively small. The setting is more reasonable, and the firmness of the connection with the chair frame as the seat body is higher.

[0041] In addition, in addition to controlling the changing spatial curve of the peripheral wall of the aluminum frame 100, in some embodiments, the upper wall and the lower wall of the aluminum frame 100 also have unique spatial curves. Figure 2 , the first concave 110 and the second concave 120 are both arc-shaped structures. Further, the first convex portion 210 can be stably mounted on the first concave 110, and the second convex portion 310 can be stably mounted on the second concave 120. Figure 1, the first concave 110 and the second concave 120 are arranged up and down on the aluminum frame 100, adapted to the application scenario where the aluminum frame 100 is arranged horizontally. Correspondingly, the first convex portion 210 is installed on the lower side of the aluminum frame 100, and the second convex portion 310 is located on the upper side of the aluminum frame 100. Further, in order to better limit the first convex and / or second convex portion 310, to ensure the stability of the installation of the first plastic block 200 and the second plastic block 300. In some embodiments of the utility model, a tilting portion 130 is provided on the side of the second concave 120 away from the first concave 110, and the tilting portion 130 abuts against the side of the second convex portion 310 away from the first convex portion 210, further limiting the position of the second convex portion 310.

[0042] The above description has been given of the support and limiting structures of the aluminum frame 100, the first plastic block 200 and the second plastic block 300. In some embodiments of the present invention, for example, the fixing method between the aluminum frame 100, the first plastic block 200 and the second plastic block 300 is as follows: Figure 3 As shown, considering that the first plastic block 200 is a part mainly used to connect the support 600 and the armrest body 500, the first plastic block 200 and the aluminum frame 100 are fixed by connecting screws 400 to ensure the stability of the connection between the first plastic block 200 and the aluminum frame 100, and the aluminum frame 100 can better shape the first plastic block 200 to avoid deformation of the first plastic block 200 after long-term use. In addition, the second plastic block 300 mainly plays the role of a decorative cover. Optionally, the connecting screw 400 is located inside the first plastic block 200 and the second plastic block 300, so that the outer surface of the adapter assembly has no exposed screws, the surface is smooth, and the user is convenient to clean and has good aesthetics. Among them, the second plastic block 300 is fixed with the first plastic block 200 by clamping. For example, the first plastic block 200 is provided with a clamping groove 201, and the second plastic block 300 is provided with a clamping block 301 that is clamped and matched with the clamping groove 201. The two are easy to disassemble and assemble, and it is convenient to install and replace the parts inside the first plastic block 200.

By adopting an aluminum-plastic combined armrest adapter assembly according to the embodiment of the utility model, the aluminum frame 100 can support and fix the shape of the first plastic block 200, improve the stability of the first plastic block 200 and the chair frame or the armrest body 500 when installed and used, thereby reducing the amount of bending deformation, maintaining the consistency of the position of the armrest body 500 after long-term use, and improving user usability; and the aluminum frame 100 is a spatial bending structure, which effectively reduces the amount of material used and makes the overall structure lighter; in addition, the second plastic block 300 fills the aluminum frame 100, and cooperates with the first plastic block 200, so that the shape design is more unique, the texture changes brought by the different materials are obvious, and the aesthetics are better.
