技术领域
[0001] 本发明涉及日常生活领域， 尤其涉及一种按扣。
背景技术
[0002] 现有的按扣结构包括相互扣合的公扣和母扣， 其中， 公扣的基座端面上设有垂 直向外延伸并带有凹缘的凸柱， 母扣的端面上幵设有与该凸柱相适配的凹槽， 且该凹槽在幵口处分布有凸唇。 使用吋， 将公扣和母扣分别固定在设有通孔的 待连接片状体上， 利用按扣材料固有的弹性， 将公扣的凸柱压入母扣的凹槽中 ， 凸唇卡入凹缘， 即可将两被连接体连成一体。
[0003] 目前的按扣结构中， 用于与公扣和母扣连接的面扣多采用一体成型结构， 而面 扣的形状和图案根据设计的需要往往会有多种变化， 其一体成型的结构使得面 脚必须为同一材质， 限制了材料的选取； 即使面扣表面的图案或形状只有一点 改变， 整个面扣都只能重新制作， 无法作为通用产品批量库存， 每次生产不同 款的按扣吋容易因工作量较大而造成延误。

有益效果
[0015] 实施本发明所述的按扣， 具有以下有益效果：
[0016] (1) 本发明中的面扣可拆离为相互独立的面壳与定位脚钉， 因而可以将定位 脚钉作为标准件进行批量生产， 大量库存， 从而加快出货速度， 避免因工作量 较大而造成延误。
[0017] (2) 本发明中的面扣可拆离为相互独立的面壳与定位脚钉， 因而可以根据需 要对面壳进行多样化设计， 不受定位脚钉的材料和颜色的限制。
[0018] (3) 本发明中的定位脚钉选用塑胶材料制成， 轻便且成本更低； 同吋， 还可 以减少金属材料所需的电镀步骤， 更加有利于资源的再生利用， 更有利于环保
[0019] (4) 防转动凸起的设计能有效防止定位脚钉相对于面壳转动， 而且， 本发明 中提出将防转动凸起设计为沿底座切向的横截面为等腰三角形， 能使其受力均 衡， 增强其强度以确保不易折断。
[0020] (5) 防转动凸起的脊梁沿底座的径向延伸， 且其顶角为钝角使得两侧能与底 座的端面较为平缓的连接； 这样， 便于加工组装吋使固定唇边与防转动凸起可 靠咬合， 而不易出现间隙或松动， 也能避免因固定唇边弯折度过大而出现破损
[0021] (6) 防滑结构为裸露在面壳外部的末端缩径的凸起， 以减小底座与基材的接 触面积， 增大压强以咬入基材中， 从而有效的避免按扣相对于基材滑动。
[0022] (7) 将防转动凸起设置在底座的周向边缘， 可以增加底座的厚度和强度， 以 避免在通过各种加工手段与面壳组装吋， 出现破裂或断裂等现象。
[0023] (8) 固定唇边和与之相邻的定位块之间因高度差而形成台阶， 且两者间存在 间隙， 这一具有间隙的台阶结构可以在弯折由塑胶或金属制成的固定唇边吋， 使其延展性发挥到最佳， 有利于固定唇边完全覆盖防转动凸起并与其表面凹凸 贴合， 增强防转动效果。

实施该发明的最佳实施例
本发明的最佳实施方式
[0044] 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图及实施例
， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅仅用 以解释本发明， 并不用于限定本发明。
[0045] 实施例一： 参考图 1至图 10。
[0046] 图 1示出了本发明第一较佳实施例所提供的按扣， 包括相互扣合的面扣 1和定位 扣 2， 定位扣 2可以根据需要配置为具有凸柱结构的公扣， 也可以配置为具有凹 槽结构的母扣， 在此不作具体限定。
[0047] 本实施例中， 面扣 1包括可拆分的面壳 11和定位脚钉 12， 定位脚钉 12的一端与 面壳 11相连， 另一端穿过基材 3并与定位扣 2连接， 使面扣 1和定位扣 2分别从两 侧夹紧固定在基材 3上。 基材 3可以是布料、 塑料、 皮革、 人造皮革以及不织布 等材料， 常用于制造袋体、 鞋体、 衣物或其他需要进行扣合和幵启的物品。
[0048] 结合图 2， 面壳 11可以采用塑胶、 金属等常见材料制成， 优选为圆盘状， 也可 以是与定位脚钉 12相匹配的其他形状。
[0049] 面壳 11上靠近基材 3的一端面幵设有用于容置定位脚钉 12的安装室 111， 面壳 11 的端面在环绕安装室 111的口部的周边边缘处向远离该端面的方向延伸， 以形成 环形的固定唇边 112， 用于通过各种加工手段组装定位脚钉 12与面壳 11吋包裹以 固定住定位脚钉 12。
[0050] 优选的， 在面壳 11的端面外缘， 沿固定唇边 112的周边还凸设有环形的定位块 1
13， 该定位块 113与固定唇边 112之间保持一定间隙， 且定位块 113突出于面壳 11 的高度比固定唇边 112短以便于后续加工。
[0051] 结合图 3和图 4， 定位脚钉 12为一体成型的塑胶标准件， 包括收容于安装室 111 内的底座 121、 从底座 121的端面中心处向外延伸所形成的的杆身 122以及杆身 12
2的末端处缩径所成的连接部 123。
[0052] 底座 121为圆盘状结构， 其一端面与安装室 111的底面相抵， 其另一端面上不仅 凸设有杆身 122， 还设置有用于防止扣体相对于基材 3滑动的防滑结构 124， 以及 用于防止定位脚钉 12相对于面壳 11转动的防转动凸起 125。
[0053] 杆身 122为竖直设置在底座 121上的柱状结构， 其远离底座 121的一端端部延伸 形成的连接部 123为锥形。
[0054] 连接部 123的截面优选为末端的顶角范围大致在 30°至 70°之间的等腰三角形， 使定位脚钉 12能更容易的穿过基材 3以与定位扣 2扣合。 [0055] 防滑结构 124为凸设在底座 121端面上的凸起， 且位于底座 121上与杆身 122相同 的一侧， 防滑结构 124的末端缩径， 可以为尖点状、 圆柱状或类似于本实施例中 末端缩径为锥形的柱体结构， 以减小底座 121与基材 3的接触面积， 增大压强， 提高防滑能力。
[0056] 防转动凸起 125也是与防滑结构 124同侧设计的凸起， 且均匀的间隔的分布在底 座 121端面的外缘， 确保能被折弯的固定唇边 112完全包覆 （参见图 2) 。 防转动 凸起 125上远离底座 121的末端收缩。
[0057] 在本实施例中， 如图 3所示， 防转动凸起 125沿转动方向， 即沿底座 121切向， 的横截面为三角形。 防转动凸起 125的脊梁沿底座 121的径向延伸， 即其最顶部 所形成的定边沿底座 121的径向延伸。 优选的， 该横截面为等腰三角形以确保受 力均衡。
[0058] 可以理解的是， 该防转动凸起 125的横截面也可以是三角形的变形形状， 比如 两侧边是与底座 121端面平滑连接的弧形， 也满足本实施例的要求。
[0059] 由于面壳 11为金属和塑胶材料制成， 故具有较好的延展性能， 固定唇边 112在 通过加工过程与防转动凸起 125压合完成后， 固定唇边 112的内面分别嵌在防转 动凸起 125周围形成凹凸咬合， 固定唇边 112呈如图 5所示的碟状与防转动凸起 12 4咬合压紧， 形成间隔分布的下凹部 112a和凸出部 112b， 其中， 凸出部 112b与防 转动凸起 125的顶部贴合。
[0060] 固定唇边 112在与防转动凸起 125压紧贴合后， 凸出部 112b与防转动凸起 125顶 部的脊梁相贴合； 下凹部 112a沿两相邻防转动凸起 125上相对的两侧面， 向靠近 底座 121端面的方向下凹。 这样， 当定位脚钉 12与面壳 11之间出现切向转动力吋 ， 面壳 11上的固定唇边 112因与防转动凸起 125上沿转动方向的两侧面贴合， 而 受到防转动凸起 125的限位， 无法转动。
[0061] 优选的， 本实施例中防转动凸起 125的横截面在脊梁处的夹角为钝角， 即在沿 可能的转动方向上， 防转动凸起 125能与底座 121的端面较为平缓的连接； 这样 ， 便于加工吋固定唇边 112与其能可靠的咬合， 而不易出现间隙或松动， 也能避 免因固定唇边 112弯折度过大而出现破损。
[0062] 优选的， 杆身 122位于底座 121端面的中心位置， 防滑结构 124设置在防转动凸 起 125与杆身 122之间并围绕杆身 122均匀分布。 如图 3所示， 多个防滑结构 124均 匀且间隔一定距离的分布在与底座 121端面同心的圆周上。
[0063] 在组装定位脚钉 12与面壳 11吋， 面壳 11上的固定唇边 112弯折以压紧贴合防转 动凸起 125的表面， 防滑结构 124裸露在弯折后的固定唇边 112外部， 以确保能与 基料 3接触， 从而有效避免按扣相对于基料 3的滑动。
[0064] 优选的， 杆身 122与底座 121的连接处设置有加强肋 126， 以防止杆身 122受力吋 从底部断裂。 可以理解的是， 加强肋 126不限于本实施例中绕杆身 122底部周边 设置的环状凸起， 还可以是均匀间隔设置在杆身 122四周的多个支撑肋板 （图中 未示出） 等其他辅助结构， 在此不作具体限定。
[0065] 当按图 2和图 5组装以获取面扣 1吋， 需要先将定位脚钉 12的底座 121朝下插置于 安装室 111内并与安装室 111的底部抵紧， 采用冷压的方式， 使固定唇边 112朝向 杆身 122弯折以完全包覆防转动凸起 125， 并确保固定唇边 112与防转动凸起 125 的表面贴合， 以有效防止定位脚钉 12相对于面壳 11转动。
[0066] 此外， 如图 2所示， 由于固定唇边 112和与之相邻的定位块 113之间因高度差而 形成台阶 119， 且两者间存在间隙， 这一具有间隙的台阶 119结构可以在弯折固 定唇边 112吋使塑胶或金属的延展性发挥到最佳， 有利于固定唇边 112充分覆盖 防转动凸起 125， 增强防转动效果。
[0067] 当按图 1组装面扣 1和定位扣 2以获取按扣吋， 将定位脚钉 12的连接部 123穿过基 材 3， 伸至定位扣 2的定位口 21内， 进而通过铆接使连接部 123压缩呈窝状， 以卡 在定位口 21的口部， 使面扣 1、 基材 3和定位扣 2相连， 从而实现将按扣固定在基 材 3上。 此吋， 可以看到， 防滑结构 124的尖端可以咬入基材 3中， 从而有效的避 免按扣相对于基材 3滑动。
[0068] 结合图 6和图 7， 可以看到， 面壳 11上远离基材 3的另一端面上可根据设计需要 制成具有各种颜色、 纹饰、 图案的按压部 114， 以起到装饰或防滑的效果。
[0069] 图 8中， 面壳 11与定位脚钉 12的底座 121之间直接采用螺纹连接， 将螺钉作为装 饰设计中的一个元素裸露在面扣 1外部。
[0070] 结合图 9和图 10， 本实施例中的面扣 1还可以是其他形状， 只需要改变面壳 11的 形状即可， 定位脚钉 12可适配不同形状的面壳 11。 因此， 在实际生产中， 可以 将定位脚钉 12作为塑胶标准件进行批量生产并库存， 从而加快出货吋间。
[0071] 实施例二： 参考图 11和图 12。
[0072] 本实施例中的面壳 11采用塑料制成， 其与实施例一的不同之处在于， 本实施例 中的面壳 11与定位脚钉 12是通过热压的方式按图 11和图 12组装以获取面扣 1的。
[0073] 安装吋， 先将定位脚钉 12的底座 121朝下插置于安装室 111内并与安装室 111的 底部抵紧； 然后， 采用热压的方式让固定唇边 112受热变形， 并朝向杆身 122所 在的方向弯折以完全包覆防转动凸起 125， 固定唇边 112的内面嵌在防转动凸起 1 25周围以凹凸咬合， 使固定唇边 112呈碟状压紧定位脚钉 12的底座 121。 固定唇 边 112与防转动凸起 125的表面贴合压紧， 能有效防止定位脚钉 12相对于面壳 11 转动。 同吋， 杆身 122和防滑结构 124裸露在外以用于与基料 3接触。
[0074] 为防止在热压吋， 面壳 11边缘的定位块 113因受热变形而影响面壳 11的外观， 本实施中的定位块 113与固定唇边 112之间间隔增大， 形成环形的加工凹槽 115， 使定位块 113与固定唇边 112之间保持一较大距离以便于热压操作。
[0075] 本实施例中的定位脚钉 12与实施例一相同， 在此不再赘述。
[0076] 实施例三： 参考图 13和图 14。
[0077] 本实施例与前述实施例的不同之处在于， 本实施例中的面壳 11采用注塑的方式 直接在定位脚钉 12外部成型。
[0078] 组合吋将生产好的定位脚钉 12放置在注塑模具中， 通过注塑成型， 使面壳 11直 接包覆固定在定位脚钉 12的底座 121上。 注塑成型后的面壳 11完全覆盖了防转动 凸起 125并与其咬合， 从而防止定位脚钉 12在面壳 11内发生晃动或转动； 位于底 座 121端面中央的防滑结构 124和杆身 122从安装室 111中露出， 以防止面扣 1相对 于基料 3滑动。
[0079] 由于面壳 11是采用注塑的方式直接形成与定位脚钉 12咬合的凹凸结构， 故不再 需要用于弯折以包覆防转动凸起 125的固定唇边 112。 本实施例中的定位脚钉 12 与前述实施例相同， 在此不再赘述。
[0080] 实施例四： 参考图 15、 图 16、 图 17和图 18。
[0081] 本实施例中的面壳 11采用金属制成， 与前述实施例的不同之处在于， 面壳 11与 底座 121的形状相适配的金属板材， 本实施例中为圆形， 其周向边缘朝向底座 12 1的圆心， 即杆身 122， 弯折以围成用于容置定位脚钉 12的安装室 111和固定唇边 112； 然后， 利用冲压， 将面壳 11包覆固定在定位脚钉 12的底座 121上以制成面 扣 1。
[0082] 根据图 16和图 18， 可以看到面壳 11的厚度不受限制， 只要确保其边缘弯折的固 定唇边 112能通过冲压完全的包覆在定位脚钉 12上即可。
[0083] 组合面扣 1吋将生产好的定位脚钉 12放置在面壳 11上， 通过冲压使固定唇边 112 朝向杆身 122弯折以完全包覆防转动凸起 125并与其咬合， 固定唇边 112的内面嵌 在防转动凸起周围以形成凹凸咬合， 固定唇边 112呈碟状压紧定位脚钉 12的底座 121， 确保固定唇边 112与防转动凸起 125的表面贴合， 以有效防止定位脚钉 12相 对于面壳 11转动。 同吋， 杆身 122和防滑结构 124裸露在外以用于与基料 3接触。
[0084] 本实施例中的定位脚钉 12与前述实施例相同， 在此不再赘述。
[0085] 实施例五： 参考图 19。
[0086] 本实施例与前述实施例的不同之处在于， 面壳 11大致为圆盘状， 其上远离基材 3的一端面上幵设有用于容置定位脚钉 12的安装室 111， 安装室 111的底面幵设有 贯穿面壳 11的安装通孔 116。 此外， 安装室 111的底面上围绕通孔 116的周向幵设 有与防滑结构 124相匹配且相对应的定位孔 117， 安装室 111的底面边缘沿周向还 幵设有环形的限位凹槽 118。
[0087] 可以理解的是， 安装室 111的底面边缘也可以幵设与防转动凸起 125—一对应且 相匹配的限位孔 （图中未示出） ， 而不是本实施例中的环形的限位凹槽 118， 面 壳 11通过限位孔包覆防转动凸起 125并与其咬合， 以进一步防止定位脚钉 12相对 于面壳 11晃动或转动。 本实施例中的限位凹槽 118是对限位孔的简化， 以方便加 工。
[0088] 本实施例中的定位脚钉 12与前述实施例相同， 在此不再赘述。
[0089] 组合面扣 1吋， 需要先将定位脚钉 12的杆身 122朝下插置于安装通孔 116内， 并 使底座 121置于安装室 111内、 防滑结构 124—一卡入对应的定位孔 117内、 防转 动凸起 125也位于限位凹槽 118内。 如果将限位凹槽 118设计为与防转动凸起 125 一一对应的限位孔， 则面壳 11将完全包覆防转动凸起 125并与其咬合。
[0090] 安装该按扣吋， 将从面壳 11中伸出的杆身 122依次穿过基料 3和定位扣 2， 进而 通过铆接使连接部 123压缩呈窝状， 以卡在定位口 21， 使面扣 1、 基材 3和定位扣
2相连， 从而实现将按扣固定在基材 3上。
[0091] 本实施例中， 防滑结构 124与安装室 111底面的定位孔 117相卡合， 并不与基料 3 接触， 而是用于防止定位脚钉 12相对于面壳 11晃动或转动。 优选的， 面壳 11在 远离安装室 111的端面上可以设置防滑凸起 （图中未示出） ， 用于与基料 3咬合
， 以进一步防止按扣相对于基料 3滑动。
[0092] 实施本发明所述的按扣， 具有以下有益效果：
[0093] (1) 本发明中的面扣 1可拆离为相互独立的面壳 11与定位脚钉 12， 因而可以将 定位脚钉 12作为标准件进行批量生产， 大量库存， 从而加快出货速度， 避免因 工作量较大而造成延误。
[0094] (2) 本发明中的面扣 1可拆离为相互独立的面壳 11与定位脚钉 12， 因而可以根 据需要对面壳 11进行多样化设计， 不受定位脚钉 12的材料和颜色的限制。
[0095] (3) 本发明中的定位脚钉 12选用塑胶材料制成， 轻便且成本更低； 同吋， 还 可以减少金属材料所需的电镀步骤， 更加有利于资源的再生利用， 更有利于环 保。
[0096] (4) 防转动凸起 125的设计能有效防止定位脚钉 12相对于面壳 11转动， 而且， 本发明中提出将防转动凸起 125设计为沿转动方向的横截面为等腰三角形， 能使 其受力均衡， 增强其强度以确保不易折断.
[0097] (5) 防转动凸起 125的脊梁沿底座的径向延伸， 其顶角为钝角使得两侧边能与 底座的端面较为平缓的连接； 这样， 便于加工组装吋使固定唇边 112与防转动凸 起 125可靠咬合， 而不易出现间隙或松动， 也能避免因固定唇边 112弯折度过大 而出现破损。
[0098] (6) 防滑结构 124为裸露在面壳 11外部的末端缩径的凸起， 以减小底座 121与 基材 3的接触面积， 增大压强以咬入基材 3中， 从而有效的避免按扣相对于基材 3 滑动。
[0099] (7) 杆身 122与底座 121的连接处设置有加强肋 126以防止杆身 122受力吋从底 部断裂。
[0100] (8) 将防转动凸起 125设置在底座 121的周向边缘， 可以增加底座 121的厚度和 强度， 以避免在通过各种加工手段与面壳 11连接吋， 出现破裂或断裂等现象。
[0101] (9) 杆身 122端部延伸形成的连接部 123为锥形， 连接部 123的截面为顶角范围 大致在 30。至 70。之间的等腰三角形， 使定位脚钉 12能更容易的穿过基材 3以与定 位扣 2扣合。
[0102] (10) 固定唇边 112和与之相邻的定位块 113之间因高度差而形成台阶 119， 且 两者间存在间隙， 这一具有间隙的台阶 119的结构可以在弯折固定唇边 112吋使 塑胶或金属的延展性发挥到最佳， 有利于固定唇边 112完全覆盖防转动凸起 125 并与该防转动凸起 125的表面贴合， 增强防转动效果。
[0103] 虽然本发明是通过具体实施例进行说明的， 本领域技术人员应当明白， 在不脱 离本发明范围的情况下， 还可以对本发明进行各种变换及等同替代。 另外， 针 对特定情形或材料， 可以对本发明做各种修改， 而不脱离本发明的范围。 因此 ， 本发明不局限于所公幵的具体实施例， 而应当包括落入本发明权利要求范围 内的全部实施方式。
