【具体实施方式】
为使本发明的上述目的、 特征和优点能够更加明显易懂， 下面结合附图对 本发明的多个具体实施方式做详细的说明。 在下面的描述中阐述了 4艮多具体细 节以便于充分理解本发明， 但是本发明能够以很多不同于在此描述的其它方式 来实施， 本领域技术人员可以在不违背本发明内涵的情况下做类似改进， 因此 本发明不受下面公开的具体实施的限制。 在没有明确否定的情况下， 其中一个 实施例的技术特征也可以有益地与其他一个或多个实施例相互结合。
请同时参阅图 1和图 2, 实施例一的壁挂式固定装置 100包括支撑装置 11 和可拆卸地设于该支撑装置 n的固定支架 13。
支撑装置 11 包括设于墙壁上的基座 111和设于该基座 111上的挂钩 113。 本实施例中， 基座 111可以被认为是一种用以支撑挂钩 113的支撑物。 基座 111 大致为橢圓形塑料盘， 其可通过贴膜、 胶粘或螺丝固定等方法固定在卫生间或 阳台的墙壁 W (见图 3)上。 挂钩 113包括设置于基座 111的表面靠近底端的位置 的相连部 115和朝上方折弯延伸的顶部 117。挂钩 113的外侧具有平滑过渡的曲 面 119。 挂钩 113可以由具有弹性的材料构成， 例如塑料或金属。
固定支架 13包括两个固定杆 131。 两个固定杆 131由硬质材料构成， 例如 铁线、 扁铁线、 不锈钢线等。 两个固定杆 131 大致沿竖直方向平行延伸， 两个 固定杆 131 的顶端朝远离基座 111或墙壁的方向垂直折弯延伸， 并相互连接形 成用于支撑重物的支撑部 132。 本实施例中， 该支撑部 132为从两个固定杆 131 的顶端向外垂直延伸， 然后向下并朝靠近基座 111 的方向弯曲形成的钩形。 如 图 2所示， 该钩形可用于支撑固定晾晒毛巾的长 4†R。
固定支架 13还包括设于两个固定杆 131上的挂钩抵压件 135和支撑物抵压 件 137。 本申请文件中， "设于" 二字的意思包括直接固定于其上， 也包括间接 相连。 挂钩抵压件 135和支撑物抵压件 137的材料可以选有具有弹性的材料制 成。 本实施例中， 固定支架 13包括一个设于该两个固定杆 131上的连接环 133。
连接环 133大致呈矩形， 其包括相互平行的挂钩抵压件 135和支撑物抵压 件 137。挂钩抵压件 135大致沿水平方向延伸， 并通过焊接等方式固定在两个固 定杆 131的靠近支撑部 132的一侧。支撑物抵压件 137的两端与挂钩抵压件 135 的两端分别相连。请参阅图 3 ,设挂钩抵压件 135与支撑物抵压件 137之间的最 大距离 （二者最外围的边缘的距离）为 a, 挂钩 113的顶部 117与基座 111的最 小距离 （水平距离）为 b, 挂钩 113的顶部 117至挂钩 113与基座 111的相连部 115的 巨离为 c, 则 b<a<c。
两个固定杆 131位于连接环 133下方的位置还设有止挡件 139。 止挡件 139 与挂钩抵压件 135或支撑物抵压件 137相互平行。 两个固定杆 131、 止挡件 139 和挂钩 4氏压部 135围成的过孔的面积大于挂钩 113的横截面面积， 因此挂钩 113 可以延伸穿过该过孔。 另外， 止挡件 139和挂钩 4氏压部 135的最小距离 D小于 挂钩 113的垂直高度 L (见图 5 )。 本实施例中， 止挡件 139为通过焊接的方式 固定在两个固定杆 131上的一根横杆， 在其他实施例中， 止挡件 139也可以与 两个固定杆 131是一体成型的， 还可以为两根短杆。
两个固定杆 131的底端朝靠近墙壁 W的方向折弯。 壁挂式固定装置 100还 包括设于两个固定杆 131的底端的摩擦垫 15。 摩擦垫 15可以与墙壁 W相抵， 用于提供阻止负重物及壁挂式固定装置 100下坠的摩擦力。 摩擦垫 15的材料优 选为高静摩擦系数的硅胶。
由于硅胶类材料具有蠕变 (creep)的现象， 即摩擦垫 15在受力时会逐渐沿施 力方向移动， 因此， 在一个实施例中， 摩擦垫 15与墙壁 W相贴合的一面还可 以设有凹凸不平的， 类似汽车轮胎表面的花纹， 以减少蠕变现象。
在另一实施例中， 在两个固定杆 131的底端设有可以与墙壁 W相氏的硬质 衬块。 更为优选的方案中， 硬质衬块与墙壁 W相贴合的表面涂覆有用于增大摩 擦力的涂层。 该涂层的材料为高摩擦力的材料， 例如橡胶类 （包含硅胶）、 PU 或 TPR类塑料。硬质衬块与墙壁 W相贴合的一面也可以设有凹凸不平的， 类似 汽车轮胎表面的花纹。
图 3至图 5显示了固定支架 13安装到支撑装置 11时的全过程， 详细描述
:¾口下。
请参阅图 3 , 当需要将固定支架 13安装到支撑装置 11时， 由于止挡件 139 和挂钩抵压部的最小距离 D小于挂钩 113的垂直高度 L, 因此无法将两个固定 杆 131以保持竖直的状态与挂钩 113扣合。 可首先将连接环 133以一定的角度 倾斜后再放入到挂钩 113与基座 111的间隙中。由于挂钩抵压件 135与支撑物抵 压件 137之间的最大距离 a小于挂钩 113的顶部 117至相连部 115的距离为 c, 因此挂钩抵压件 135与支撑物抵压件 137都可位于挂钩 113与基座 111的间隙内， 且挂钩抵压件 135与挂钩 113相抵， 支撑物抵压件 137与基座 111的相连部 115 相抵。
请参阅图 4, 当对两个固定杆 131的底部施加如图所示方向的力时， 固定支 架 13会沿挂钩抵压件 135与挂钩 113相接触的部位逆时针翻转。 止挡件 139也 会沿着挂钩 113外侧的曲面 119滑动。 由于两个固定杆 131、 止挡件 139和挂钩 抵压部 135围成的过孔的面积大于挂钩 113的横截面面积， 因此挂钩 113可以 延伸穿过该过孔。由于挂钩抵压件 135与支撑物抵压件 137之间的最大距离为 a 大于挂钩 113的顶部 117与基座 111的最小距离 b, 因此翻转时挂钩抵压件 135 会将具有弹性的挂钩 H3撑开一小段距离， 而同时挂钩抵压件 135与支撑物抵 压件 137之间的距离也可被压缩一小段，使挂钩 113与基座 111的距离与挂钩抵 压件 135与支撑物抵压件 137的距离相同， 即连接环 133所在的平面与基座 111 垂直。 此时， 固定支架 13处于一种不稳定的临界状态。
请参阅图 5 , 当固定支架 13沿支撑物抵压件 137与基座 111的相接触的部 位继续逆时针翻转时， 在挂钩 113及挂钩 4氏压件 135、 支撑物 4氏压件 137的回复 弹力的作用下， 挂钩抵压件 135会加速滑入挂钩 113的底部， 到达翻转的终点。 如此， 可给予操作者一种良好的操作手感。 此时， 挂钩 113位于两个固定杆 131 之间， 挂钩抵压件 135与挂钩 113相抵， 支撑物抵压件 137与基座 111相抵， 摩 擦垫 15与墙壁 W相抵。 由于挂钩 113恢复成原来形状， 阻止固定支架 13沿图 示 X轴方向运动， 而止挡件 139与挂钩 4氏压件 135分别位于挂钩 113的上下两 侧， 且止挡件 139和挂钩抵压部 135的最小距离 D小于挂钩 113的垂直高度 L, 可以阻止固定支架 13沿图示 Y轴方向移动后沿垂直于墙壁 W的方向将固定支 架 13取出， 因此可将固定支架 13牢牢地固定在支撑装置 11上。
当需要将固定支架 13从支撑装置 11上取下时， 可以对两个固定杆 131的 底部反向施力， 使固定支架 13顺时针翻转。 在翻转的初期， 需使用较大的力以 克服挂钩 113及挂钩抵压件 135与支撑物抵压件 137的弹力， 但当挂钩抵压件 135与支撑物抵压件 137移动经过图 4所示的临界位置之后，便可较为轻松地将 固定支架 13从支撑装置 11上取下。
现在分析壁挂式固定装置 100 的受力情况。 为了方便起见， 分析时忽略固 定支架 13和支撑装置 11的重量因素。
首先定义支撑部 132的受力中心与挂钩 4氏压件 135的水平距离为 H; 挂钩 抵压件 135与摩擦垫 15的垂直距离为 V； 摩擦垫 15的静摩擦系数为 μ。假设支 撑部 132承载的重物的重力为 ； 墙壁给摩擦垫 15的支撑力为 N; 挂钩 113受 到的压力（即挂钩 113对固定支架 13的支撑力）为 Fh; Fh的受力方向与 Y轴的 夹角为 θ。
以挂钩抵压件 135为支点， 按照力矩平衡， 有
Fi · Η=Ν · V (I) 将固定支架 13视为一个整体，则其主要受到四个力， 包括重物的重力为 Fl 墙壁对摩擦垫 15的支撑力 N, 墙壁对摩擦垫 15的静摩擦力 Νμ, 及挂钩 113对 固定支架 13的支撑力为 Fh, 按照受力平衡， 有
Fh 2=N2+ (Fj-Νμ) 2 (II), 且 cosG-^^ (III); 联立式（1)、 (II), 得到
Fh 2= [S2+ (8μ) 2-28μ+ l]xFi2 (IV);
式（IV) 中， S=H/V。 上式（III )表明，挂钩 113受到的压力与支撑部 132承载的重物的重力有关， 且当 S2 + ( 8μ ) 2 - 28μ + 1的值最小时，使挂钩 113受到的压力最小。 由此可得， 当 8=μ/(1+μ2) ( V ) 时， 挂钩 113受到的压力最小， 此时， 大部分重物的重力由墙壁对摩擦垫 15的 静摩擦力所支持。
如果把（V )代入到 （III ) 式， 得到
COS0 = T ( VI ) 若挂钩 113对固定支架 13的支撑力为 Fh刚好同时穿过挂钩抵压件 135与支 撑物抵压件 137,即沿着连接挂钩抵压件 135与支撑物抵压件 137的两个短臂的 方向施力， 则此时固定支架 13的受力最为稳定。 因此挂钩氏压件 135和支撑物 抵压件 137 所定义的平面与固定杆 131 (即竖直方向） 所成角度优选为
Figure imgf000011_0001
举例来说：承载重力 10Kg;承载物重心至挂钩抵压件 135水平距离 5厘米； 挂钩抵压件 135至摩擦垫 15垂直距离 15厘米； 采用与瓷砖墙面最大静摩擦系 数 2.5的硅胶垫， 计算得： 钩件受力 3.7Kg; 挂钩 133受力方向与竖直方向的夹 角 63.7°
从此例知，挂钩 133只承受全部外力的 37 % (其余外力由摩擦垫承受）， 而受 力方向与墙面夹角 63.7。 ，这对于是吸着或黏着于墙面的支撑装置 11是有利的， 因为此类支撑装置 11若受与墙面平行的向下的力，对吸盘或黏着材料容易损伤， 同时破坏吸着或黏着力， 使其难持久而容易脱落； 这种向下延伸长一定距离的 摩擦垫结构不但可大大承担支撑装置 11 的负荷， 同时对支撑装置 11起到保护 作用。
另外， 这种摩擦垫结构需向下延伸很长的距离才能产生功效， 对于室内外 用具， 若仍采用常用的塑料材料， 由于是长距离下受大负荷， 塑料结构体必须 做得很宽很厚很大， 不但各种成本高 （材料、 制造生产、 包装、 运输、 销售陈 列）， 而且发生小的被承载物确要大的支撑结构， 不但形成空间浪费， 在外观设 计上也处理起来^艮困难。 而用铁或不锈钢线类（包括扁铁或钢)做成支架， 不但成 本低， 占空间小， 且因其纤细， 视觉上占空间感少， 而使外观设计筒单容易。
可以理解， 如果挂钩 113直接设置在墙壁上， 基座 111也可省略。 此时， 支 撑物抵压件 137可以直接与墙壁相抵。 也就是说， 挂钩 113直接设置在墙壁上 时， 墙壁可以作为支撑物； 挂钩 113通过基座 111设置在墙壁上时， 基座 111 可以作为支撑物。
上述实施例中，挂钩 113、挂钩 4氏压件 135和支撑物 4氏压件 137均具有弹性， 但是可以理解， 这三者其中一个具有弹性即可实现本发明之目的。
以下对其他实施例进行描述。 应该指出的是， 以下其他实施例的支撑装置 与实施例一的支撑装置结构大致相同， 区别均在于固定支架的改变。 在没有刻 意做出否定的情况下， 实施例一的特征和优势也可以有机的结合到以下其他实 施例中， 以下其他实施例的特征和优势也可以有机的结合到实施例一中。
请参阅图 6,实施例二壁挂式固定装置与实施例一的壁挂式固定装置 100的 结构大致相同， 其不同之处在于： 固定支架 23包括两个相互平行的固定杆 231 和设于两个固定杆 231且相互平行的挂钩抵压件 235和支撑物抵压件 237。
挂钩抵压件 235通过焊接等方式固定在两个固定杆 231的靠近支撑部 （图 未示） 的一侧。 支撑物抵压件 237通过焊接等方式固定在两个固定杆 231 的远 离支撑部的一侧。 即， 挂钩抵压件 235和支撑物抵压件 237分别设于两个固定 Η 231所定义的平面的两侧。
请同时参阅图 7,设挂钩抵压件 235与支撑物抵压件 237之间的最大距离（二 者最外围的边缘的距离）为 a, 挂钩 213的顶部 217与基座 211的最小距离 （水 平距离 )为 b, 挂钩 213的顶部 217至挂钩 213与基座 211的相连部 215的距离 为 c, 贝1 J b<a<c。
与实施例一相比， 实施例二的固定支架 23用料更少， 结构更筒单， 外形更 佳。
请参阅图 8 ,实施例三 a的壁挂式固定装置与实施例二的壁挂式固定装置的 结构大致相同， 其不同之处在于： 该固定装置还包括设置于挂钩抵压件 335 与 挂钩 313之间的弹性件 334。
弹性件 334可以为弹簧、 金属弹片、 弹性塑胶或橡胶等。 本实施例中， 弹 性件 334为可压缩的弹簧， 其一端与挂钩 4氏压件 335相氏， 另一端与挂钩 313 相抵。如前所述，摩擦垫 35在受力时会发生蠕变现象，但是当设置了弹性件 334 之后， 使得在没有放置重物时固定支架被弹性件 334顶在最高位置； 放上重物 后， 弹性件 334能够被压缩， 使得摩擦垫 35向下蠕动一段距离， 摩擦垫 35可 提供较大的向上的支撑力； 当取下负重后， 弹性件 334的弹力能将固定支架 33 弹起， 以将摩擦垫 35顶到最高位置， 如此下次负重时又可重新开始蠕动。
设弹性件 334的最小弹力为 Fsmin、 最大弹力为 Fsmax; 固定支架 33 (无外加 重物 ) 的重力为 Wf; 摩擦垫 35的静摩擦系数为 μ; 固定支架 33的重心到挂钩 抵压件 335的水平距离为 Hf;挂钩抵压件 335到摩擦垫 35的铅垂方向距离为 V； 外加重物的重力为 W1, 贝' J :
Fsmin < Wf + Wl ( VII )
否则弹性件 334无法被压缩， 也就没有蠕动容许距离或行程。
另有： Fsmax > Wf + μ χ Wf x Hf/V ( VIII )
否则移除外加重物时， 弹性件 334无法将固定支架 33弹起。
请同时参阅图 9和图 10,在实施例三 b中，弹性件 334包括第一固定环 3341、 第二固定环 3343及多个弹性圏 3345。第一固定环 3341和第二固定环 3343大致 为方形。 每个弹性圏 3345大致为橢圓形。 多个弹性圏 3345的首尾相连， 然后 连接第一固定环 3341和第二固定环 3343。 本实施例中， 弹性件 334的材质可以 为一种名叫杜邦海翠的弹性塑胶。 这种结构的弹性塑胶在被压缩时， 无论压缩 量是多少， 可以保持相同的弹力， 有利于稳定。 使用时， 第一固定环 3341套设 于卡钩 313的顶部， 第二固定环套 3343设于卡钩 313的底部， 且最顶部的一个 弹性圏 3345与挂钩抵压件 335相抵。 可以理解， 第一固定环 3341和第二固定 环 3343也可省略。
请参阅图 11 ,实施例四的壁挂式固定装置与实施例一的壁挂式固定装置 100 的结构大致相同， 其不同之处在于： 固定支架 43包括两个平行的固定杆 431和 连接两个固定杆 431的挂钩抵压件 435。挂钩抵压件 435的两端折弯形成两个支 撑臂 436。 支撑物抵压件 437为套设于两个支撑臂 436上， 并与挂钩抵压件 435 平行的的套筒。 两个支撑臂 436的末端相互间隔， 形成一间隙 434, 以方便该套 筒通过该间隙 434套设在两个支撑臂 436上。
套筒优选为由光滑的塑料制成， 例如 PE (聚乙烯）或 POM (聚曱醛）。 请一并参阅图 12, 设挂钩抵压件 435与支撑物抵压件 437之间的最大距离 (二者最外围的边缘的距离）为 a, 挂钩 413的顶部 417与基座 411的最小距离 (水平 巨离 )为 b, 挂钩 413的顶部 417至挂钩 413与基座 411的相连部 415的 巨离为 c, 贝1 j b<a<c。
实施例四中， 两个固定杆 431的顶端朝远离基座 411的方向垂直折弯延伸， 并相互连接形成用于支撑重物的支撑部 432。 本实施例中， 该支撑部 432为圓环 形。 该圓环形的支撑部 432可用于支撑固定脸盆等底座为圓形的器具。 可以理 解， 支撑部 432也可以为方形等其他形状。
请参阅图 13和图 14,实施例五的壁挂式固定装置与实施例四的壁挂式固定 装置的结构大致相同， 其不同之处在于： 壁挂式固定装置还包括设置于挂钩抵 压件 535与挂钩 513之间的弹性件 534。
请一并参阅图 15 , 弹性件 534可以为弹簧、 金属弹片、 弹性塑胶或橡胶等。 本实施例中， 弹性件 534 为具有弹性的金属丝， 该金属丝的两端分别固定于两 个支撑臂 536, 金属丝的中部与挂钩 513与基座 511的相连部相抵。 可以理解， 若省略基座 511 , 则金属丝的中部与挂钩 513与墙壁的相连部相抵。
请参阅图 16 ,实施例六的壁挂式固定装置与实施例一的壁挂式固定装置 100 的结构大致相同， 其不同之处在于： 实施例六的固定支架 63包括两个平行的固 定杆 631和连接两个固定杆 631的挂钩抵压件 635。挂钩抵压件 635的两端折弯 形成支撑臂 636, 支撑物 4氏压件 637为形成于两个支撑臂 636末端的支撑帽。
请参阅图 17, 支撑帽的形状可以为球状、 橢球状或者其他能使支撑臂 636 与基座 611点接触的形状。 本实施例中， 支撑帽为套设在支撑臂 636末端的材 料为 PE或 POM的塑料帽。 支撑帽的表面比较光滑， 从而可以避免使用时支撑 臂 636与墙壁 W或基座 611直接接触而将其划伤。 请一并参阅 18 , 设挂钩抵压件 635与两个支撑物抵压件 637之间的最大距 离 （二者最外围的边缘的距离）为 a, 挂钩 613的顶部 617与基座 611的最小距 离 （水平距离 )为 b, 挂钩 613的顶部 617至挂钩 613与基座 611的相连部 615 的 巨离为 c, 则 b<a<c。
请参阅图 19 ,实施例七的壁挂式固定装置与实施例一的壁挂式固定装置 100 的结构大致相同， 其不同之处在于： 挂钩抵压件 735 的厚度（或直径）较粗， 且支撑物抵压件为由两个固定杆 731的顶端朝远离基座 711 (或墙壁）的方向折 弯形成的两个折弯部 733。
请一并参阅图 20,设挂钩抵压件 735与两个折弯部 733之间的最大距离（二 者最外围的边缘的距离）为 a, 挂钩 713的顶部 717与基座 711的最小距离 （水 平距离 )为 b, 挂钩 713的顶部 717至挂钩 713与基座 711的相连部 715的距离 为 c, 贝1 J b<a<c。
请参阅图 21 ,实施例八的壁挂式固定装置与实施例一的壁挂式固定装置 100 的结构大致相同， 其不同之处在于： 支撑物抵压件为形成于两个固定杆 831 顶 端的两个支撑帽 834。
支撑帽 834的形状可以为球状、橢球状或者其他能使固定杆 831与基座 811 点接触的形状。 本实施例中， 支撑帽 834为套设在固定杆 831末端的材料为 PE 或 POM的塑料帽。
请一并参阅图 22 ,设挂钩抵压件 835与两个支撑帽 834之间的最大距离（二 者最外围的边缘的距离）为 a, 挂钩 813的顶部 817与基座 811的最小距离 （水 平距离 )为 b, 挂钩 813的顶部 817至挂钩 813与基座 811的相连部 815的距离 为 c, 贝1 J b<a<c。
两个固定杆 831上靠近两个支撑帽 834的部位设有一个环形的卡合件 832。 两个固定杆 831上靠近摩擦垫 85的位置还设有支撑件 838。 支撑件 838可与该 卡合件 832相配合， 用于固定水瓶、 水桶或纸篓。
请一并参阅图 23和图 24, 实施例九的壁挂式固定装置 200包括支撑装置 91和可拆卸地设于该支撑装置 91的固定支架 93。
支撑装置 91包括设于墙壁上的基座 911和设于该基座 911上的挂钩 913。 本实施例中， 基座 911可以被认为是一种用以支撑挂钩 913的支撑物。基座 911 大致为橢圓形塑料盘， 其可通过贴膜、 胶粘或螺丝固定等方法固定在卫生间或 阳台的墙壁上。 挂钩 913 包括设置于基座 911 的表面靠近底端的位置的相连部 (未标示）和朝上方折弯延伸的顶部 9131。 挂钩 913的外侧具有平滑过渡的曲 面 919。 挂钩 913的底部还设有一个卡合凸起 9191。
固定支架 93包括大致为方形的支撑板 931和从支撑板 931靠近基座 911的 一端垂直向下折弯延伸形成的固定板 933。
支撑板 931靠近固定板 933的一侧设有一个具有弹性的定位凸起 9311。 如 图 24所示，定位凸起 9311至支撑物 911的最大距离设为 J,挂钩 913的顶部 9131 至支撑物 911的最小距离为 K, 则 J K。
请一并参阅图 25 , 固定板 933上开设有供挂钩 913穿过的过孔 935。 固定 板 933位于过孔 935的边缘形成有弹性的卡合条 937。固定板 933由具有弹性的 材料构成， 例如塑料或橡胶等。 固定板 933 上靠近两侧边缘的位置分别开设有 一个长条形的第一变形孔 9331。 固定板 933上位于过孔 935和卡合条 937之间 还开设有连通两个第一变形孔 9331的末端的长条形的第二变形孔 9333。
下面结合图 23至图 24详细说明固定支架 93安装到支撑装置 91的全过程。 当需要将固定支架 93安装到支撑装置 91 时， 首先使挂钩 913穿过固定板 933 上的过孔 935 , 并使固定板 933位于挂钩 913的顶部 9131与基座 911之间。 当 卡合条 937沿曲面 919滑动至与卡合凸起 9191的左侧相抵时， 支撑板 931上的 定位凸起 9311刚好与挂钩 913的顶部 9131相 4氏。 当对支撑板 931的末端施加 如图 24所示方向的力 F时， 固定支架 93会逆时针翻转。 由于卡合条 937具有 弹性， 因此其可发生弹性变形而越过卡合凸起 9191 , 并最终被卡合于卡合凸起 9191与基座 911之间。 同时， 具有弹性的定位凸起 9311也会发生弹性变形， 从 而进入挂钩 913与基座 911之间。 由于定位凸起 9311至支撑物 911的最大距离 J小于等于挂钩 913的顶部 9131至支撑物 911的最小距离 K, 因此， 定位凸起 9311最终会与挂钩 913的顶部 9131内侧相氐， 阻止固定支架 93进一步的逆时 针翻转， 同时也能阻止固定支架 93顺时针旋转， 从而将固定支架 93牢牢地固 定在支撑装置 91上。 固定支架 93上可以堆放卫生间使用的各类杂物， 例如脸 盆， 肥皂等等。
请参阅图 26, 当需要将固定支架 93从支撑装置 91上拆除时， 可以用手挤 压固定板 933的两侧， 使两个第一变形孔 9331被压扁， 同时第二变形孔 9333 扩张， 即使得卡合条 937朝远离挂钩 913的方向运动， 从而使卡合条 937与卡 合凸起 9191脱离。 此时， 顺时针旋转固定支架 93便可将固定支架 93从支撑装 置 91上取下， 整个过程较为方便快捷。
可以理解， 由于卡合条 937是弹性的， 如果直接用手将卡合条 937朝外拉 动， 也可以使其绕过卡合凸起 9191 , 因此第一变形孔 9331及第二变形孔 9333 也可省略。 另外， 如果固定板由刚性材料构成， 则卡合条 937及卡合凸起 9191 也可省略。
可以理解， 卡合凸起 9191也可以设于实施例一至实施例八的挂钩底部， 从 而将止挡件卡合于卡合凸起与支撑物之间。
由上述多个实施例可知， 本发明的壁挂式固定装置使用相同的支撑装置可 以匹配不同的固定支架以实现不用的用途。 而且上述壁挂式固定装置还具有结 构筒单， 使用方便的优点。
但并不能因此而理解为对本发明专利范围的限制。 应当指出的是， 对于本领域 的普通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干变形和 改进， 这些都属于本发明的保护范围。 因此， 本发明专利的保护范围应以所附 权利要求为准。
