Description

一种旋转伞座 技术领域
本实用新型涉及户外遮阳伞技术领域，涉及一种遮阳伞的伞座，尤其涉及一种旋转伞座。
背景技术
遮阳伞作为一种户外休闲用具，广泛用于广场、海滩、公园及庭院等休闲场所，为人们提供了舒适的乘凉空间。
现有的遮阳伞的伞座形式多样，材料也多种，为了保持与伞盖的平衡，伞座的体积均较大或重量较重。目前常用的通常为一个可填充的空心座体，座体内设有伞柄插孔，整个座体为塑胶注塑一体成型，使用时在座体内充入水或细沙等填充物以平衡座体的重心便于座体***伞柄后更加稳定，但是这种结构的伞座往往体积庞大，自重很大，不仅不方便运输还增加制造和包装运输的成本。另外，目前的遮阳伞的伞座都是固定的，不能旋转。
经查，现有专利号为CN200720052619.2的中国实用新型专利《一种便于固定伞柄的太阳伞座》，其包括可填充的空心座体，座体中心的插孔中插设有连接管，连接管端部螺纹连接有伞柄套筒，套筒为双层结构，内层套筒侧壁开有多条通槽形成弹性卡环，外层套筒内壁设有螺纹，连接管锥形斜面与伞柄套筒的弹性卡环配合将弹性卡环推向套筒内侧收拢，卡紧伞柄。该伞座可实现对不同规格伞柄的握紧，从而可防止伞柄在座体孔内晃动磨损孔壁，延长了伞座的使用寿命，但是其结构笨重、体积较大，而且伞座也是不能旋转，使用不够灵活方便。
发明内容
本实用新型所要解决的技术问题是针对上述的技术现状而提供一种结构合理、操作灵活方便的旋转伞座。
本实用新型解决上述技术问题所采用的技术方案为：一种旋转伞座，其特征在于：包括旋转底座、套管焊接件和脚踏板组件，其中套管焊接件包括套管和底板，套管竖直插置在底板的上端面中部位置与底板焊接固定，旋转底座套设在套管外、位于底板上方，遮阳伞的立柱的下端套设在套管外与旋转底座插接定位，脚踏板组件包括脚踏板和脚踏轴，脚踏板可复位转动地安装在旋转底座的上端一侧，脚踏轴竖直设置在脚踏板里侧的下端，脚踏轴穿过旋转底座与底板上的定位孔相配合、并通过脚踏板实现与底板的锁紧 与脱离，从而实现旋转底座的定位锁定与旋转。
作为改进，所述旋转底座为中部开孔的圆形底座，在旋转底座的中部开孔位置成型有一圆筒形的凸台，套管的下端穿过凸台的内孔与底板焊接固定，套管的顶部开口位置设有伞座管塞，套管的上端套设有一旋转块，旋转块可随立柱旋转而转动地套设在套管上端通过伞座管塞限位。
再改进，所述伞座管塞为与套管的内孔相配合的圆柱形结构，伞座管塞的上端设有与套管的上端面相抵的凸沿，在伞座管塞的下端径向开设有连接销孔，套管上开设有对应的连接孔，通过一限位销穿过连接孔、连接销孔将伞座管塞与套管定位，限位销的外端设有与旋转块的下端相抵限位的延长部，旋转块可转动地套设在套管上、限位在限位销与伞座管塞的凸沿之间。
再改进，所述旋转底座的上端一侧凸设有二块用于安装脚踏板的安装板，安装板上靠近外端的位置开设有安装孔，脚踏板的下端凸设有二个与安装板配合的连接耳，连接耳上开设有内外二个连接孔，其中外连接孔与安装板的安装孔相对应，通过转轴穿过安装板的安装孔、连接耳的外连接孔将脚踏板可上下转动地安装在旋转底座上，在脚踏板与旋转底座之间设有可使脚踏板复位的弹性件。
进一步，所述旋转底座上位于二块安装板之间的中部靠近内侧的位置纵向开设有供脚踏轴穿置的贯穿孔，脚踏轴的上端径向开设有销孔，脚踏轴的上端插置在脚踏板的二个连接耳之间、且与脚踏板的底部具有一定间距，通过圆柱销穿过连接耳的内侧的连接孔、销孔、另一侧连接耳的连接孔将脚踏轴的上端与连接耳相连接，底板上靠近外边缘的位置环向间隔开设有若干个与旋转底座的贯穿孔相对应、供脚踏轴的下端插置定位的定位孔，当向下踩下脚踏板时，脚踏轴在脚踏板的带动下向上移动从定位孔中脱离，旋转底座可旋转。
再进一步，所述弹性件为一扭簧，扭簧套设在转轴上，扭簧的一端支撑在旋转底座的上端面上，另一端支撑在脚踏板的底部后端。
再进一步，所述脚踏板的里端设有向下弯折的弯折部，当脚踏板复位时，弯折部与旋转底座的上端面相抵，脚踏板的下端面设有与脚踏轴的上端相对应的凸部，当向下踩下脚踏板、脚踏轴向上移动与底板脱离时，该凸部与脚踏轴的上端相抵，实现脚踏板下踩达到最大限度的限位。
最后，所述旋转底座上沿凸台的外侧设有供立柱插置的凹槽，立柱同时套设在凸台和旋转块外，立柱的下端插置在旋转底座的凹槽内定位，凸台的形状与旋转块相同，凸台与旋转块的外周面上均成型有与立柱的内壁面配合的定位导向凹筋。
与现有技术相比，本实用新型的优点在于：设置旋转底座、套管焊接件和脚踏板，立柱插置在旋转底座和套管焊接件上，套管焊接件起到固定支撑作用，旋转底座起到带动立柱旋转的作用，脚踏板通过脚踏轴起到旋转底座与套管焊接件的卡紧与脱离；使用 时，只要踩下脚踏板，使得脚踏轴与套管焊接件分离，就可以根据将旋转底座进行旋转，立柱也随之旋转，旋转到位后，松开脚踏板，脚踏轴与套管焊接件插接定位，旋转底座固定。本实用新型结构简单、操作方便、使用稳定可靠，可轻松实现伞座的旋转，从而调节遮阳伞的位置，值得推广。

具体结构为：在旋转底座1的中部开孔位置成型有一圆筒形的凸台10，套管21的下端穿过凸台20的内孔与底板22焊接固定，旋转底座1上沿凸台10的外侧设有供立柱20插置的凹槽，套管21的顶部开口位置设有伞座管塞5，伞座管塞5为与套管21的内孔相配合的圆柱形结构，伞座管塞5的上端设有与套管21的上端面相抵的凸沿51，套管21的上端套设有一旋转块4，旋转块4的形状与凸台10相同，立柱20同时套设在凸台10和旋转块4外，立柱20的下端插置在旋转底座1的凹槽内定位，凸台10与旋转块4的外周面上均成型有与立柱20的内壁面配合的定位导向凹筋，这样旋转块4可随立柱20旋转而转动，在伞座管塞5的下端径向开设有连接销孔52，套管21上开设有对应的连接孔211，通过一限位销6穿过连接孔211、连接销孔52将伞座管塞5与套管21定位，限位销6的外端设有与旋转块4的下端相抵限位的延长部，旋转块4可转动地套设在套管21外、限位在限位销6与伞座管塞5的凸沿51之间；旋转底座1的上端一侧凸设有二块用于安装脚踏板31的安装板11，安装板11上靠近外端的位置开设有安装 孔111，脚踏板31的下端凸设有二个与安装板11配合的连接耳311，连接耳311上开设有内外二个连接孔312和313，其中外连接孔313与安装板11的安装孔111相对应，通过转轴8穿过安装板11的安装孔111、连接耳311的外连接孔313将脚踏板31可上下转动地安装在旋转底座1上；旋转底座1上位于二块安装板11之间的中部靠近内侧的位置纵向开设有供脚踏轴32穿置的贯穿孔，脚踏轴32的上端径向开设有销孔321，脚踏轴321的上端插置在脚踏板31的二个连接耳311之间、且与脚踏板31的底部具有一定间距，通过圆柱销9穿过连接耳311的内连接孔312、销孔321、另一侧连接耳311的内连接孔312将脚踏轴32的上端与连接耳311相连接，底板22上靠近外边缘的位置环向间隔开设有若干个与旋转底座1的贯穿孔相对应、供脚踏轴32的下端插置定位的定位孔221，当向下踩下脚踏板31时，脚踏轴32在脚踏板31的带动下向上移动从定位孔221中脱离，旋转底座1可旋转，在脚踏板31与旋转底座1之间设有可使脚踏板21复位的弹性件；弹性件为一扭簧7，扭簧7套设在转轴8上，扭簧7的一端支撑在旋转底座1的上端面上，另一端支撑在脚踏板31的底部后端，使脚踏板31具有始终向上转动，使脚踏轴32***底板22的定位孔221的趋势；为了对脚踏板31进行转动限位，脚踏板31的里端设有向下弯折的弯折部314，当脚踏板31复位时，弯折部314与旋转底座1的上端面相抵，脚踏板31的下端面设有与脚踏轴32的上端相对应的凸部315，当向下踩下脚踏板31、脚踏轴32向上移动与底板22脱离时，该凸部315与脚踏轴32的上端相抵，实现脚踏板31下踩达到最大限度的限位。
需要旋转伞座时，踩下脚踏板31，圆柱销8带动脚踏轴32向上移动与套管焊接件2的底板22脱开，如图3所示，脚踏板31下踩后内侧的凸部315与脚踏轴32上表面4相接触，脚踏板31下踩达到最大限度，旋转底座1的凸台10外形与旋转块4外形一致，外部立柱20同时套置于旋转底座1和旋转块4，左右转动脚踏板31就可实现旋转底座1的转动，从而带动外部立柱20的转动。
转动到位后，松开脚踏板31，在扭簧7的作用下脚踏板31复位，脚踏轴32向下移动***底板22的定位孔221中，脚踏板31前端的弯折部314与旋转伞座1上表面相抵接触，伞座定位锁紧，如图4所示。
以上所述仅是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本实用新型的保护范围。
