Description

Technical Field

[0001] The utility model relates to the field of seat frame structures, and particularly to a retractable sofa armrest skeleton. Background Technique

[0002] In the designs of existing massage sofas, single sofas, multi-person sofas, etc., there are often relatively large armrests, and the armrests include armrest skeletons, armrest fillers, and armrest skins.

[0003] Foreign-funded enterprises mainly purchase armrest skeletons in our country. However, when the armrest skeleton is transported as a whole, it occupies a large volume, and the freight cost has been rising in recent years, resulting in a decline in corporate profits. Content of the Utility Model

[0004] The purpose of the utility model is to provide a retractable sofa armrest skeleton to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A retractable sofa armrest skeleton, including a pair of armrest clamping plates, a fixed plate, a limiting sleeve, and a pair of pulling components. The armrest clamping plates are in the shape of a rectangular frame, and horizontal reinforcing bars are respectively fixedly installed on the upper and lower parts of the armrest clamping plates. The pair of armrest clamping plates are arranged opposite and parallel to each other. Each pulling component includes a pair of fixed pieces, a pair of rotating pieces, and a tension spring. The two fixed pieces are respectively fixed on the adjacent reinforcing bars of the pair of armrest clamping plates. The two rotating pieces are arranged parallel to each other, and both ends of each rotating piece are rotatably fixed on the two fixed pieces. A fixed pile is also fixedly installed on each fixed piece. The two ends of the tension spring are respectively clamped on the fixed piles of the two fixed pieces.

[0006] Preferably, both ends of the fixed plate are fixedly installed on the adjacent side walls of the pair of armrest clamping plates.

[0007] Preferably, the limiting sleeve includes a barrel-shaped body and a clamping ring formed at one end of the body.

[0008] Preferably, the body is embedded in the upper part between the pair of armrest clamping plates. The end of the body away from the clamping ring abuts against the end of the fixed piece on the reinforcing bar installed on the upper part of the armrest clamping plate, and the inner side wall of the clamping ring abuts against the outer side wall of the armrest clamping plate.

[0009] Preferably, two rotating shafts are formed on each fixed piece, and rotating holes are formed at both ends of each rotating piece. The two rotating pieces are arranged parallel to each other, and the rotating holes of each rotating piece are respectively rotatably arranged on the rotating shafts.

[0010] Preferably, a limiting block is formed at a position of one of each pair of fixing pieces close to the rotating shaft, and the limiting block abuts against the side of the rotating piece away from the limiting sleeve.

[0011] The purpose of the present utility model is to overcome the deficiencies of the prior art, and a retractable sofa armrest skeleton is designed. By designing a pair of pulling components, when transporting, only the fixing plate and the limiting sleeve need to be removed, and then the pair of armrest clamping frames can be brought close together by using the pulling components, thereby greatly reducing the volume of the present utility model. As a result, the number of the present utility models that can be loaded in the container is doubled. Moreover, because the present utility model not only has a simple structure but also is very easy to operate. After unloading, only need to pull the armrest clamping frame apart so that the side wall of the rotating piece abuts against the limiting block, then fix the fixing plate with bolts, and then insert the limiting sleeve. After combination, the structure of the present utility model is stable. Description of the Drawings
