本实用新型涉及显示牌技术领域，特别是涉及一种可变式号码牌。
背景技术
随着人们生活水平的提高和汽车工业的快速发展，汽车已成为人们出行的普通代步工具。然而，随着汽车的普遍使用，无论是小区住宅还是商场、办公楼等公共场所，都存在停车位严重紧缺的问题。因此，很多车主在需要短时间停车却找不到停车位时，通常会将汽车临时停靠在路边，并在车上放置电话号码牌，在有需要时方便他人第一时间联系车主挪车，方便自己的同时也兼顾着他人。
然而，现有电话号码牌一经设置不能更改，在实际使用时存在一系列的不便。例如，一般家庭都是夫妻二人共同使用一部汽车，如此导致换人使用时还需要更换电话号码牌；另外在除临时停车的大部分时间里，将电话号码公之于众，会造成车主私人信息的泄漏，给不法分子可乘之机，因此又必要对现有号码牌进行改进。

具体实施方式
为了便于理解本实用新型，下面将参照相关附图对本实用新型进行更全面的描述。附图中示例性地给出了本实用新型的一个或多个实施例，以使得本实用新型所公开的技术方案的理解更为准确、透彻。但是，应当理解的是，本实用新型可以以多种不同的形式来实现，并不限于以下所描述的实施例。
如图1及图2所示，本实用新型可变式号码牌包括外筒10、设置于外筒10内并可相对于外筒10转动的内筒20、驱动内筒20转动以切换显示信息的驱动机构30以及用于使得内筒20单向转动的止回件40。
本实施例中，所述外筒10整体为中空筒状，外壁面具有一平表面部或支撑部，使得可以稳定地横放于其它物件上，如放置于车内。所述外筒10的侧壁上设置有窗口12，用于显示内筒20上对应该窗口12位置处的信息22。所述内筒20为圆筒状，可转动地安装于外筒10内。
外筒10具有相对的外筒第一端101和外筒第二端102，相应地，内筒20具有相对的内筒第一端201和内筒第二端202，内筒20具有沿其轴向延伸的转动轴线X。驱动机构30设置于外筒第一端101，并且驱动机构30与内筒第一端201之间形成第一棘轮机构，第一棘轮机构构造成使得驱动机构30能够驱动内筒20相对外筒10沿第一方向R1进行单向转动，第一方向R1环绕转动轴线X；止回件40设置于外筒第二端102，止回件40于内筒第二端202之间形成第二棘轮机构，第二棘轮机构允许内筒20相对外筒沿第一方向R1转动但阻止内筒20沿第二方向R2转动，第二方向R2环绕转动轴线X并与第一方向R1相反。
更具体地，外筒第一端101设有第一端盖105，第一端盖105沿外筒10的轴向延伸形成一第一轴杆1051；外筒第二端102设有第二端盖106，第二端盖106沿外筒10的轴向延伸形成一第二轴杆1061，内筒第一端201和内筒第二端202的中央均形成有用于与第一轴杆1051和第二轴杆1061相插接的轴孔，如此第一端盖105和第二端盖106与内筒20形成可转动连接，支撑内筒20的转动。
所述外筒第一端101具有一安装部，所述安装部内形成腔室18，驱动机构30安装在腔室18内。所述驱动机构30包括操作件31、由操作件31驱动的驱动件33以及推动操作件31复位的弹性复位元件36。
其中，所述操作件31活动地设置于外筒第一端101的腔室18中，在本实施例中，所述操作件31优选以滑动地方式设置于外筒第一端101的腔室18中，对应地，腔室18上形成有横向的滑槽19，操作件31可沿滑槽19往复滑动。操作件31包括齿条311和操作柄313，操 作柄313凸出于滑槽19之外或者以其他适当的方式暴露于外筒10之外，方便使用者推动齿条311滑动。
第一棘轮机构包括相互配合的第一棘轮部331和第二棘轮部24。
请同时参阅图3，驱动件33为一套设于第一轴杆1051的齿轮，第一棘轮部331设置于驱动件33的一端，并且第一棘轮部331与驱动件33同步转动。第一棘轮部331设有若干棘齿，每一棘齿具有一最高点、一最低点、斜面以及驱动面。在本实施例中，第一棘轮部331设置两个棘齿333、334，以棘齿333为例，棘齿333具有一最高点335和一最低点336，斜面337连接于最高点335和最低点336之间，驱动面338连接于棘齿333的最高点335和棘齿334的最低点339之间。
齿条311与驱动件33啮合，齿条311滑动时带动驱动件33转动，同时带动第一棘轮部331转动。应当理解的是，在其他实施例中，操作件31也可以通过旋转等活动方式设置于外筒10的腔室18中，例如将操作件31同样设置为齿轮，只要实现操作件31带动驱动件33转动即可。
在本实施例中，第一弹性偏压元件37为弹簧。第一弹性偏压元件37套设于第一轴杆1051上，并设置于驱动件33和第一端盖105之间，第一弹性偏压元件37的一端抵触在驱动件33的侧面上，另一端抵触在第一端盖105的内侧，使得第一弹性偏压元件37朝向内筒第一端201对驱动件33施加一弹性偏压。
在本实施例中，弹性复位元件36为弹簧。弹性复位元件36设置于滑槽19内，并与齿条311的末端相连接。本实施例中，齿条311在其末端形成有凸柱314，弹性复位元件36套设于凸柱314上。操作件31可在第一位置(如图4所示)和第二位置(如图5所示)之 间往复滑动，在操作件31在第一位置和第二位置的至少其中之一位置，内筒20上的信息22由窗口12对外显示。如图4所示，当操作件31在第一位置时，弹性复位元件36处于复位状态，使用者推动齿条311朝向其末端方向滑动压缩弹性复位元件36，并带动驱动件33逆时针方向转动，直至操作件31位于第二位置停止；如图5所示，当操作件31位于第二位置时，弹性复位元件36处于压缩状态，使用者松开操作件31，弹性复位元件36恢复形变驱动齿条311反向滑动复位，带动驱动件33顺时针方向转动，直至操作件31位于第一位置停止。
内筒第一端201(图式为右端)沿轴向向外凸出形成第二棘轮部24，第二棘轮部24的直径小于内筒20的外径，第二棘轮部24与内筒20一体成型，两者同步转动。第一棘轮部331由驱动件33朝向第二棘轮部24的一侧向外伸出至第二棘轮部24的位置，第二棘轮部24的侧面上对应第一棘轮部331形成有若干棘齿，在本实施例中，第二棘轮部24设置两个棘齿241、242，棘齿241、242与第一棘轮部331的棘齿333、334朝向相反，第一棘轮部331通过棘齿333、334的驱动面与棘齿241、242的驱动面相作用而驱动第二棘轮部24朝向第一方向R1转动。
第二棘轮机构包括相互作用的第三棘轮部41和第四棘轮部26。
请同时参阅图6，止回件40设置于外筒第二端102并套设于第二轴杆1061上，第三棘轮部41形成于止回件40朝向内筒第二端202的一侧，止回件40的内侧壁上设有止回滑槽43，第二轴杆1061上设有止回滑轨45，止回滑轨45滑动设置于止回滑槽43内以限制止回件40相对第二轴杆1061转动。可变式号码牌包括第二弹性偏压元件47，在本实施例中，第二弹性偏压元件47为弹簧。第二弹性偏压 元件47套设于第二轴杆1061上并设置于止回件40和第二端盖106之间，第二弹性偏压元件47一端抵触在止回件40的侧面上，另一端抵触在第二端盖106的内侧，并朝向内筒第二端202对止回件40施加一弹性偏压。内筒第二端202形成有用于与第三棘轮部41配合的第四棘轮部26，与第一棘轮部331和第二棘轮部24类似地，第三棘轮部41和第四棘轮部26上形成有若干棘齿，在本实施例中，第三棘轮部41设置两个棘齿411、412，第四棘轮部26设置两个棘齿261、262，第三棘轮部41通过棘齿411、412的驱动面和棘齿261、262的驱动面相作用而阻止第四棘齿部26沿第二方向R2转动，从而使得内筒20只能单向转动。
内筒20相对外筒10转动，切换在外筒10的窗口12处显示的信息22。在本实施例中，所述内筒20的外周面上设置有两项信息22(如图7和图8)，图式为“12345678901”与“12345678902”，可以理解地，此为示意性表示，并非实际信息。所述两项信息22在周向上相距180度，也就是说，内筒20每转动半圈，外筒10的窗口12处显示的信息22切换一次。对应于内筒20上的N项显示信息22，第一棘轮部331、第二棘轮部24、第三棘轮部41以及第四棘轮部26上设置N个棘齿，如本实施例中第一棘轮部331、第二棘轮部24、第三棘轮部41以及第四棘轮部26对应内筒20上设置的两项信息22均设置两个棘齿。
本实施例中，以用于临时停车为例，所述内筒20上的两项信息22均为电话号码，所述两个电话号码可以是同一人的不同号码，如工作电话与私人电话等；也可以是不同人的号码，如夫妻两人的两个号码等，如此可以根据实际的使用者、使用的时间场合等显示相应的联系电话。可以理解地，所述内筒20上可以设置N(N为不小于2 的整数)项信息22，如三项、五项等，对应地每切换一次信息22，内筒20需要转动1/N圈，如三项信息22时内筒20每次转动1/3圈、五项信息22时内筒20每次转动1/5圈等、十项信息22时内筒20每次转动1/10圈等。
所述内筒20上的各项信息22可以全部是具体信息内容，如上述实施例中两项信息22都是电话号码。在如图9和图10所示的实施例中，所述各项信息22中一项信息22为空白信息(或是图案、文字等装饰内容)，如两项信息22分别为电话号码和空白信息。在设有空白信息22时，可以在某些情况下将使用者个人信息隐藏，如在路边临时停车时，可以将内筒20转动至显示相应的电话号码，方便他人联系车主挪车；而在自家车库等规定的停车位停车时，可以将内筒20转动至显示空白信息位置，避免暴露车主个人信息，给不法份子可趁之机。也可以只设置一项信息22，而第一棘轮部331、第二棘轮部24、第三棘轮部41以及第四棘轮部26均设置两个棘齿，在可变式号码牌显示信息22的情况下切换一次，窗口12显现不带有信息的内筒部分，亦能起到上述隐藏个人信息的效果，本实用新型对内筒上设置的信息22的项数不作限定。
本实用新型中，第一棘轮部331驱动第二棘轮部24带动内筒20逆时针方向转动，止回件40的第三棘轮部41则与第四棘轮部26作用禁止内筒20顺时针方向转动。第一棘轮部331与第二棘轮部24共同形成一棘轮机构，第三棘轮部41与第四棘轮部26也共同形成一棘轮机构。操作件31做往复滑动，内筒20做单向间歇转动，具体如下：
首先，请参阅图1、图7、图11及图12，本实用新型可变式号码牌在初始状态时，操作件31的操作柄313位于第一位置，此时可变式号码牌显示内筒20上的信息“12345678901”。第二棘轮部24 的棘齿241、242和第四棘轮部26的棘齿261、262朝向相反，此时第二棘轮部24的棘齿241和第四棘轮部26的棘齿261位于顶部。第一棘轮部331的棘齿333、334分别与第二棘轮部24的棘齿241、242相啮合，止回件40的第三棘轮部41的棘齿411、412分别与第四棘轮部26的棘齿261、262相啮合。当需要切换显示信息22时，如图7所示，向前推动操作件31的操作柄313压缩弹性复位元件36，带动驱动件33逆时针方向转动，第一棘轮部331推动第二棘轮部24并带动内筒20随之逆时针方向转动，直至操作件31滑止第二位置时，可变式号码牌显示内筒20上的另一项信息“12345678902”。随着内筒20的转动，第四棘轮部26逆时针转动，第四棘轮部26的棘齿261、262分别与第三棘轮部41的棘齿411、412分离，并随着第四棘轮部26的棘齿261、262和第三棘轮部41的棘齿411、412厚度的变化推动止回件40朝向第二端盖106压缩第二弹性偏压元件47。
当操作件31的操作柄313被推至第二位置时，驱动件33逆时针方向转过半圈，并带动第二棘轮部24、内筒20逆时针方向转过半圈。如图13所示，此时第二棘轮部24的棘齿242转动至顶部，第四棘轮部26的棘齿262完全越过第三棘轮部41的棘齿411后与其相啮合，类似的第四棘轮部26的棘齿261完全越过第三棘轮部41的棘齿412后与其相啮合。此时松开操作柄313，被操作件31压缩的弹性复位元件36回复弹性形变，推动操作件31反向向后滑动复位(如图4和图5)。如图14所示，在操作件31反向滑动复位的过程中，带动驱动件33以及第一棘轮部331顺时针方向转动，第一棘轮部331的棘齿333、334分别与第二棘轮部24的棘齿242、241相分离。随着第一棘轮部331和第二棘轮部24上的棘齿厚度的变化，驱动件33朝向第一端盖105压缩第一弹性偏压元件37，直至驱动件33顺时针方向 转动半圈时，如图15所示，第一弹性偏压元件37恢复弹性形变推动第一棘轮部331与第二棘轮部24相啮合。
如图13至15所示，在驱动件33顺时针方向转动半圈复位的过程中，由于止回件40的第三棘轮部41与第四棘轮部26相啮合，内筒20始终保持在转过半圈的位置不动。此时通过窗口12可以直接看到内筒20转过半圈之后的信息“12345678902”。如此，通过驱动机构30的操作件31的一次往复滑动、内筒20的半圈转动，实现显示信息22的切换。当需要再次切换显示信息22时，再次向前推动操作件31，使其再进行一次往复滑动，带动内筒20继续转动半圈，即可回到图1及图11所示状态，具体过程不再赘述。
如图16所示为内筒20上设置的两项信息22中有一项为空白信息，在需要隐藏个人信息的情况下，操作驱动结构30切换至窗口12显示空白信息的状态。
图17所示为本实用新型可变式号码牌的另一实施例，其与前述实施例的不同之处主要在于第二棘轮部24和第一弹性偏压元件37、第二弹性偏压元件47的设置。本实施例中，去除第二弹性偏压元件47，第二棘轮部24滑动设置在内筒第一端201，内筒第一端201内形成滑动空间27，内筒第一端201的内侧壁上设有限位滑槽28，第二棘轮部24的外侧壁上设有滑动设置于限位滑槽28内的限位滑轨244，限位滑槽28与限位滑轨244相作用以限制第二棘轮部24相对内筒20转动。第一弹性偏压元件37套设于第一轴杆1051的末端，更具体地，第一弹性偏压元件37设置于滑动空间27的底壁和第二棘轮部24之间，使得第一弹性偏压元件37朝向第一端盖105对第二棘轮部施加一弹性偏压，同时第一弹性偏压元件37朝向第二端盖106对内筒20施加一弹性偏压。
综上所述，可变式号码牌包括可相对转动的外筒和内筒，及驱动内筒相对外筒转动的驱动机构和用于使得内筒单向转动的止回件。驱动机构和止回件分别设置于外筒第一端和外筒第二端，驱动机构和内筒第一端之间形成第一棘轮机构，止回件和内筒第二端之间形成第二棘轮机构。第一棘轮机构构造成使得驱动机构能够驱动内筒相对外筒沿一方向进行单向转动，第二棘轮机构允许内筒相对外筒沿该方向转动但阻止内筒沿与该方向相反的方向转动。最终实现驱动机构做往复滑动，内筒做单向间歇转动。总之，本实用新型可变式号码牌可以根据需要切换显示信息，结构简单、操作简便，方便实用。
需要说明的是，本实用新型并不局限于上述实施方式，根据本实用新型的创造精神，本领域技术人员还可以做出其他变化，这些依据本实用新型的创造精神所做的变化，都应包含在本实用新型所要求保护的范围之内。
