Description

一种可升降的安全支撑护栏 技术领域
本发明实施例涉及支撑防护用品技术领域，具体涉及一种可升降安全支撑床护栏。
背景技术
本部分向读者介绍可能与本发明实施例的各个方面相关的背景技术，相信能够向读者提供有用的背景信息，从而有助于读者更好地理解本发明实施例的各个方面。因此，可以理解，本部分的说明是用于上述目的，而并非构成对现有技术的承认。
为了保证小孩子不会在爬行、玩耍时掉下床，家长们通常都会选择使用带护栏的床或者在已经有的床上增加护栏。床护栏的支撑腿一般放到床垫下而与床体固定，床护栏框架上装布套，从而能够将婴幼儿挡在床上，防止婴幼儿从床上掉落下来，确保婴幼儿的安全。另外，床垫的厚度不同也会间接对稳定性产生影响，因而存在一定的安全隐患。
为了防止儿童从护栏中爬出，现在的儿童床的护栏一般会做得比较高。虽然较高的护栏可以防止儿童从床里面爬出来，但是固定高度的护栏相对于身高较矮的人不方便对儿童的抱进、抱出；并且，现有儿童床的护栏高于成人床的床垫，造成妈妈睡在床边不方便照看。为解决这个问题，现在的床护栏一般也都具有了折叠装置，在需要将婴幼儿从床上抱下来时，可以将床护栏框架向外侧翻转并折叠放下。但是目前市场上的床护栏的折叠装置结构复杂，床护栏在折叠时操作不便，且折叠后栏杆容易摩擦到地板。另外，由于目前床垫品类众多，况且床垫高度有高有低，有些床垫较厚的情况下，增加的护栏实际高度并不高，依然有婴幼儿跌落的风险。
通常的床护栏是在两端设置了开关锁机构，两端都可以往下放打开护栏。目前市场产品的开关锁机构都采用表面或背面的按键开锁方式，表面或背面暴露定锁孔。儿童在好奇心的驱使下玩弄开关锁机构有可能造成误触开锁，导致儿童跌落。

如图2至图5所示，为了保证可升降的安全支撑护栏，在合适的高度锁定，所述内支撑柱11上纵向设置有多个升降限位孔110；所述升降锁定装置包括：升降弹性销3，所述升降弹性销3连接有拉环31；所述底部连接件上设置有一个开口30，所述升降弹性销3在所述拉环31的带动下由所述开口30内外弹性伸缩；所述内支撑柱11穿过所述底部连接件2与所述外支撑柱12对接；所述内支撑柱11与所述外支撑柱12交汇后，所述升降弹性销3从所述开口处露出，所述升降弹性销3卡入所述升降限位孔110内使所述内支撑柱11与所述外支撑柱12紧固锁定。通过升降锁定装置15可以随时解除锁定调整护栏的高度。
如图2至图5所示，所述拉环31设置在护栏外侧。拉动操作拉环31，拉环31与弹性销3联动，可以进行护栏的高度调整。在安装好可升降的安全支撑护栏的状态下，从内部婴幼儿不会触摸到拉环31和升降限位孔110，进一步提高安全性。
如图3至图6所示，所述底部连接件2中的内壁22上设置有螺母片插槽26，所述螺母片插槽26内设置有螺母片25，所述底部连接件2套接在所述外支撑柱12的底端时用螺丝 28紧固。所述外支撑柱12的底端的侧壁上开设有通孔129，螺丝29依序穿过外壁21外支撑柱12的侧壁123和内壁22后与螺母片25螺接固定稳固，可以有效保证底部连接件2与外支撑柱12固定结实，可以增加稳定性和保护内支撑柱11的表面损伤。
如图2至图7所示，还包括横杆连接部230：所述横杆连接部230包括：设置在所述底部连接件2上的横杆插口233，所述横杆插口233上设置有横杆限位孔203；所述横杆13的外径小于所述横杆插口233的内径，所述横杆13与所述横杆插口233对接将所述横杆13对接包覆于其中；所述横杆13的端部设置有横杆弹性销131，所述横杆弹性销131设置在所述横杆13内部，所述横杆13的端部的侧壁上设置有横杆通孔103，所述横杆弹性销131在所述横杆通孔103内外弹性伸缩；所述横杆的端部与所述横杆插口233交汇后，所述弹性销131从所述横杆通孔103处露出，所述横杆弹性销131卡入所述横杆限位孔203内使所述横杆13的端部与所述横杆连接部230紧固锁定。如图3至图7所示，还包括设置在所述横杆13的端部内侧的V形弹片133，所述V形弹片133包括第一臂和第二臂，所述横杆弹性销131固定在所述第一臂上，所述第二臂抵接在所述横杆13的端部内侧。
如图2至图7所示，为了能保证横杆顺利升降，本发明实施例提供的可升降的安全支撑护栏，还包括竖杆连接部260，所述竖杆连接部包括设置在所述底部连接件上的竖杆插口，所述竖杆插口内插接有供上横杆14上下滑动的竖杆16。在需要将婴幼儿从床上抱下来时，可以使上横杆14沿所述竖杆16下滑放下护栏，方便将孩子抱出。
综上所述，由上述技术方案可知，本发明实施例提供的可升降的安全支撑护栏，通过调整可以升降的支撑立柱可以有效整体改变护栏的高度，可以适用于各种不同厚度的床垫，避免了在使用较厚床垫时护栏相对较矮的问题；还可以有效避免婴孩肢体陷入床垫和床护栏之间的缝隙内，有效避免事故发生。
最后需要说明的是，在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，诸如“第一”、“第二”等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序，或者不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所 述要素的过程、方法、物品或者设备中还存在另外的相同要素。除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接或彼此通信；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
