背景技术
目前有很多的家具,都是使用金属管作为支撑,特别是对于如各种的桌子等家具来说,所采用的金属管桌腿通常由桌管和桌管支撑座相互固定连接构成,这种结构通常包括如下的2种连接的方式,1、焊接固定件与螺母直接焊接后,固定件与桌管焊接成一体,桌管支撑座内设有外六角螺纹放置位置,把外六角螺柱放入桌管支撑座外六角螺柱放置位置,螺柱与螺纹旋转配合而成。2、焊接固定件与螺柱直接进行焊接或冲压形成一体,然后与桌管焊接形成一体,桌管支撑座内设自攻螺纹,桌管与桌管支撑座用螺纹旋转配合,紧固之后形成一体;上述的这两种现有的技术方案存在有以下的缺点:1、工艺较复杂,技术含量高。需由熟练和技术高的焊接工人进行作业;2、工序多,需5个工序方能完成装配作业,做成周转困难和生产周期长,材料锈蚀严重。长时间周转增加后面生产工序磨光和电镀的工作量;3、产品成品率低。焊接经常出现焊接不牢固,有脱焊现象。需要保证之尺寸较难100%实现。电镀难度大不容易实现完美的表面电镀,焊接固定件与桌管转角位置处易产生锈蚀现象;4、桌管表面会存在严重缺陷。焊点位置在桌管处有明显的凹凸现象或穿孔现象;5、劳动强度大,焊接工人在高温环境下完成生产组装、运输及装卸;造成最终的产品成本不能得到良好的控制,导致产品的售价不具有优势难以进行市场的推广。 
实用新型内容
本实用新型是为了克服上述的缺陷,提供一种便于进行组装而且组装后具有良好的稳定性的桌管组合件。 
为达到上述目的,本实用新型的可方便组装和制造的桌管组合件采用了如下的技术方案:本实用新型的可方便组装和制造的桌管组合件,包括圆筒形的桌管、与桌管配合固定的膨胀固定组合装置和桌管支撑座,膨胀固定组合装置包括有可以相互拧紧螺母和螺栓组合、以及可以在螺母和螺栓组合的挤压下发生膨胀的膨胀块,螺栓包括有螺纹部和螺栓头,膨胀块为直径略小于桌管直径并且具有一定厚度的近似圆柱形结构,该圆柱型结构的膨胀块中心设有截面为锥形,一端为大孔开口端另一端为小孔开口端的膨胀孔,桌管支撑座上也设有固定孔,螺栓的螺纹端穿过膨胀孔和固定孔然后与螺母相互配合,膨胀块设于桌管内之后,螺母和螺栓组合相互拧紧固定。 
本实用新型的可方便组装和制造的桌管组合件中,所述螺栓的螺纹端自膨胀块的大孔开口端穿过后再自桌管支撑座上方一侧穿过固定孔,与设于桌管支撑座上的螺母相互配合。 
本实用新型的可方便组装和制造的桌管组合件中,所述螺栓的螺纹端自桌管支撑座下方一侧穿过固定孔后自膨胀块的小孔开口端穿过,然后与螺母相互配合。 
本实用新型的可方便组装和制造的桌管组合件中,所述的膨胀块的材质为工程塑料,该工程塑料材质的膨胀块的圆通壁上设有若干圆周状均匀分布的便于膨胀时向四周裂开的切缝。 
本实用新型的可方便组装和制造的桌管组合件中,所述的膨胀块的材质为铝合金,该铝合金材质的膨胀块的圆通壁上设有若干圆周状均匀分布的便于膨胀时向四周裂开的切缝。 
有益效果:本实用新型的可方便组装和制造的桌管组合件,因为采用膨胀固定的结构,因此,在所有的安装过程中不需要进行任何的焊接,通过简单的膨胀紧固的原理,可以很好地进行紧固,而且最终的产品具有良好的同心度,产品质量能够得到有效地保障,即便是非熟练的人员,也可以根据说明书来进行安装和调整,因此具有更好的实用性并且可大幅度降低成本。 
下面结合附图对本实用新型进行详细的描述,以使得本实用新型的上述优点更加明确。
