Abstract

本实用新型公开了一种防塌陷沙发骨架,它包括侧板和设有支撑杆的底座和椅背;所述底座上设有蛇形弹簧;所述蛇形弹簧通过定位线相互连接。本实用新型设计新颖、结构合理,由于沙发底座的蛇形弹簧由定位线相互连接,当底座受到外力下压时,由原来的受压处弹簧发生形变改为全部弹簧整体形变,使所有弹簧在定位线的作用下都能起到支撑的作用,无论底座的任何位置受力,都能发挥每根弹簧的最大弹性和力度,提高了使用寿命。本实用新型解决了现有技术舒适度低、易塌陷变形和使用寿命短的技术问题。

Description

一种防塌陷沙发骨架
技术领域  本实用新型属于沙发技术领域,具体涉及一种防塌陷沙发骨架。
背景技术  现有技术中的沙发骨架多是由木材制成,沙发骨架的底座部分常为两种形式,一种是由木板铺成,这种沙发虽然坚固耐用,但舒适度低,透气性也差;另一种是由弹簧组成,这种沙发的柔软度强,舒适度高,但这种沙发在长时间使用后,弹簧会失去弹性,导致坐垫塌陷变形,大大降低了舒适度,同时也降低了沙发的使用寿命。
发明内容  本实用新型的目的是解决现有技术存在舒适度低、易塌陷变形和使用寿命短的技术问题,提供一种防塌陷沙发骨架,以克服现有技术的不足。 
本实用新型一种防塌陷沙发骨架,它包括侧板和设有支撑杆的底座和椅背;所述底座上设有蛇形弹簧;其要点是所述蛇形弹簧通过定位线相互连接。
本实用新型设计新颖、结构合理,由于沙发底座的蛇形弹簧由定位线相互连接,当底座受到外力下压时,由原来的受压处弹簧发生形变改为全部弹簧整体形变,使所有弹簧在定位线的作用下都能起到支撑的作用,无论底座的任何位置受力,都能发挥每根弹簧的最大弹性和力度,提高了使用寿命。本实用新型解决了现有技术舒适度低、易塌陷变形和使用寿命短的技术问题。
附图说明 附图是本实用新型立体结构示意图。
       图中1、椅背  2、支撑杆  3、侧板  4、定位线  5、蛇形弹簧  6、底座
具体实施方式  根据附图,本实用新型它包括侧板3和设有支撑杆2的底座6和椅背1;所述底座6上设有蛇形弹簧5;所述蛇形弹簧5通过定位线4相互连接。
