Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent sofas and relates to an intelligent sofa with an adjustment function. Background Art

[0002] A smart sofa is a sofa that can realize a variety of specific functions based on the design of a traditional sofa. After searching, a Chinese patent document discloses a smart sofa based on IoT control [Application No.: 202121016946.9; Announcement No.: CN 215226202U]. The backrest of this smart sofa adopts a fixed structure and cannot be quickly adjusted according to needs. Therefore, it is necessary to design a smart sofa with adjustment function. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes an intelligent sofa with adjustment function.

[0004] The purpose of the utility model can be achieved through the following technical solutions: an intelligent sofa with adjustment function, comprising a sofa seat body, wherein the sofa seat body has armrests on both sides, characterized in that the armrests are fixed with mounting tubes, the mounting tubes are rotatably connected with a rotating shaft, a backrest is fixed between the two rotating shafts, the outer end of the mounting tube has a regular polygonal groove, the outer end of the rotating shaft has a regular polygonal block, the armrests are connected to a limiting cover through a retractable connecting belt, the limiting cover has a regular polygonal limiting ring, and the regular polygonal limiting ring can be inserted between the regular polygonal groove and the regular polygonal block.

[0005] A spring plunger is also installed on the rotating shaft, and a plurality of auxiliary positioning holes matching with the spring plunger are opened on the installation cylinder.

[0006] Four adjustable supporting legs are also installed on the sofa seat body.

[0007] The adjustable supporting leg comprises a fixing tube, an adjustable rod and a locking screw, wherein the fixing tube is connected to the sofa seat body, the adjustable rod is slidably connected to the fixing tube, the locking screw is threadedly connected to the fixing tube, and the locking screw can lock the adjustable rod.

[0008] The locking screw is a hand screw.

[0009] The armrests are all equipped with speakers, which are electrically connected to the electric control panel through lines.

[0010] Compared with the prior art, the smart sofa with adjustment function has the following advantages:

[0011] In the utility model, the backrest is rotatably connected with the sofa seat body. After being rotated to a corresponding position, a regular polygon limiting ring is inserted between the regular polygon groove and the regular polygon block, so that the angle of the backrest can be limited. Since the backrest can be rotated, the backrest can be folded inwardly on the sofa seat body during transportation, thereby reducing the transportation volume. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1-Figure 4As shown, the smart sofa with adjustment function includes a sofa seat body 1, and the sofa seat body 1 has armrests 1a on both sides. In this embodiment, the sofa seat body 1 and the armrests 1a are an integrated structure; the armrests 1a are equipped with speakers 3, and the speakers 3 are electrically connected to the electric control panel 2 through a line. This adopts the existing technology and its circuit does not need to be redesigned; the armrests 1a are fixed with mounting tubes 9, and the mounting tubes 9 are rotatably connected with a rotating shaft 8, and a backrest 6 is fixed between the two rotating shafts 8, and the outer end of the mounting tube 9 has a regular polygonal groove 9a, and the outer end of the rotating shaft 8 has a regular polygonal groove 9a. Block 8a and the handrail 1a are connected to the limiting cover 5 through a retractable connecting belt 4, and the limiting cover 5 is provided with a regular polygon limiting ring 5a, and the regular polygon limiting ring 5a can be inserted between the regular polygon groove 9a and the regular polygon block 8a. With this structure, the number of sides of the regular polygon structure is the same. When adjustment is required, the limiting cover 5 is removed, and the rotating shaft 8 can be freely rotated relative to the mounting cylinder 9. After rotating to the required position, the regular polygon limiting ring 5a is inserted between the regular polygon groove 9a and the regular polygon block 8a to limit the rotating shaft 8.

[0019] A spring plunger 8b is also installed on the rotating shaft 8, and a plurality of auxiliary positioning holes 9b that cooperate with the spring plunger 8b are opened on the mounting tube 9. With this structure, the spring plunger 8b and the auxiliary positioning holes 9b play a certain positioning role when the rotating shaft 8 rotates, so that the regular polygon restriction ring 5a can be easily inserted between the regular polygon groove 9a and the regular polygon block 8a.

[0020] Four adjustable supporting legs 7 are also installed on the sofa seat body 1; the adjustable supporting legs 7 include a fixed cylinder 7b, an adjustable rod 7a and a locking screw 7c, the fixed cylinder 7b is connected to the sofa seat body 1, the adjustable rod 7a is slidably connected to the fixed cylinder 7b, the locking screw 7c is threadedly connected to the fixed cylinder 7b, and the locking screw 7c can lock the adjustable rod 7a; the locking screw 7c is a hand-tightened screw, which can adjust the height of the entire sofa seat body 1 to meet different usage height requirements.

[0021] In the utility model, the backrest 6 is rotatably connected to the sofa seat body 1. After being rotated to a corresponding position, the angle of the backrest 6 can be limited by inserting the regular polygonal limiting ring 5a between the regular polygonal groove 9a and the regular polygonal block 8a. Since the backrest 6 can be rotated, the backrest 6 can be folded inwardly on the sofa seat body 1 during transportation, thereby reducing the transportation volume.

[0022] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0023] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
