Description

一种按压式文具的按压结构 技术领域
本发明涉及一种文具的按压结构，特别涉及一种控制按压笔的书写端或按压式修正带的压嘴伸出或收缩回壳体内的按压结构。
背景技术
现有的按压式文具主要有按压自动笔和按压式修正带，其均是通过按压按扭可使按压自动笔的笔头或按压式修正带的压嘴伸出壳体或收缩回壳体内，则使用者未使用时可将按压自动笔的笔头或修正带的压嘴收回壳体内，不受外界灰尘污染，以失去效用。
现有的按压式自动笔或按压式修正带的按压机构，其原理基本上相同。现以按压式修正带的按压机构为例，如图1、2所示，其包括安装板100、扭簧和按钮，安装板100以沿压嘴伸缩方向滑动的方式活动安装于壳体内，按钮的第一端以沿压嘴伸缩方向移动的方式安装于壳体内，并与安装板带动连接，按钮的第二端伸出壳体外，修正带的压嘴安装在安装板100的第一端上，按钮处于安装板100的第二端处，扭簧固定安装在壳体上，且扭簧的第一臂与安装板的另一面固定配合，扭簧的第二臂延伸至安装板100的第二端处，安装板100的另一面上凹设有供扭簧第二臂的端部伸入于内，并可随安装板100的移动而在其内滑动的滑动轨道101，且滑动轨道101内具有供压嘴的工作段伸出壳体时扭簧第二臂的端部限固于上的限位块102，限位块102的顶面下凹有供扭簧的第二臂挂钩在内的定位凹槽102a，滑动轨道101内凸设有与定位凹槽102a相对设置的V形导向块101a。此种按压结构，为了使扭簧的第二臂的端部能够在滑动轨道101内滑动的话，此滑动轨道101内必须设置与扭簧第二臂端面接触的第一导向阶面103、第二导向阶面104、第三导向阶面105和第四导向阶面106，以按钮的按压方向为上下方向，第一导向阶面103为由下而上向上倾斜的倾斜面，并处于限位块102的右侧，第二导向阶面104为由上而下向下倾斜的倾斜面，且第二导向阶面104低于第一导向阶面103，第三导向阶面105为由下而上向上倾斜的倾斜面，且第三导向阶面105低于第二导向阶面104，第二导向阶面104和第三导向阶面105处于限位块102的上方，第二导向阶面104的下端和第三导向阶面105的下端均处于定位凹槽102a内，第三定位凹槽102a的槽底处于第三导向阶面105处，第四导向阶面106呈由上而下向下倾斜的倾斜面，且第四导向阶面106高于第一导向阶面103，第四导向阶面处于限位块102的左侧，扭簧第二臂的轴心线处于定位凹槽102a槽底的左侧。
按压时向下按压按钮，安装板100下移，扭簧第一臂下压变形，随着安装板100的下移限位块102抵压扭簧的第二臂使扭簧的第二臂向右变形，此时随着安装板100的下移，利用扭簧第二臂的端部与第一导向阶面之间摩擦力，扭簧第二臂的端部会沿着第一导向阶面103摩擦向上移动至第二导向阶面104处时限位块102解除对扭簧第二臂的抵压，扭簧第二臂向左复位，直接移动至第二导向阶面104内，此时放开按钮，扭簧第一臂向上复位，安装板100向上移，随着安装板100的上移，扭簧的第二臂摩擦着第二导向阶面104，并沿第二导向阶面104摩擦滑入至第三导向阶面105处，并挂钩在定位凹槽102a的槽底上，即压嘴固定伸出壳体外；再次按压时，扭簧第一臂向下受压变形，安装板100再次下移，扭簧的第二臂受V形导向块101a的抵压向左变形，扭簧的第二臂从第三导向阶面105滑入至第四导向阶面106处，此时放开扭钮，扭簧第一臂向上复位，替板100向上移，并靠扭簧的第二臂的复位扭簧的第二臂沿着第四导向阶面106摩擦移动至第一导向阶面103处，即压嘴固定收缩回壳体内。由此可知，安装板100上下移动，扭簧第二臂的端部会一直对各导向阶面进行摩损，长期使用后，第三导向阶面105与第四导向阶面106之间的过渡阶面极易被磨平，造成按扭再次下压时扭簧的第二臂无法过渡至第四导向阶面106处，会滑回第三导向阶面105处，使安装板无法再次复位移动，从而造成按压结构的功能失效，通常按压100次左右后按压结构即失效，使用寿命短；同时各导向阶面的设置使安装板的结构较为复杂，不易成型。
发明内容
本发明的目的在于提供一种按压式文具的按压结构，其可使按压次数达到500次以上，使用寿命长，并使安装板的结构较为简易。
为了达成上述目的，本发明的解决方案是：
一种按压式文具的按压结构，包括安装板、弹性件和按钮，安装板以可往往平移的方式活动安装于文具壳体内，弹性体固定安装设置，以安装板的移动方向为上下方向，按钮与安装板的上端端部配合连接，且按钮的部位部位伸出文具壳体内，安装板的正面上端或背面上端凹设有凹腔，安装板位于此凹腔内凸设有限位块，该限位块的外侧壁与凹腔的内腔壁形成有一呈闭环形结构的滑动轨道，限位块的顶面下凹有定位凹槽；上述弹性件包括有随安装板的下移发生上下方向变形的弹簧和随安装板的下移发生左右方向变形的弹性杆体，上述安装板以随安装板的下移控制弹簧压缩的方式与上述弹簧配合连接，上述弹性杆体沿上下方向竖立设置，上述限位块具有处于限位块两侧的第一斜面和第二斜面，上述第一斜面的倾斜方向与上述第二斜面的倾斜方向相同，上述第一斜面的下端端部和第二斜面的下端端部共处于上述弹性杆体的一侧，上述第一斜面的上端和第二斜面的上端共处于上述弹性杆体的相对侧，上述定位凹槽处于第一斜面的上端与第二斜面的上端之间，上述弹性杆体的上端端部具有处于滑动轨道内，并随安装板的下移能分别与第一斜面和第二斜面呈面与面滑动接触配合的接触部。
上述安装板位于滑行轨道的顶面处向下凸设有朝向上述定位凹槽的限位挡块，上述限位挡块的下端端部处于上述定位凹槽内。
上述限位挡块呈V形结构。
上述弹簧为扭簧，上述扭簧固定安装于文具壳体上，上述安装板上凸设有处于扭簧第一臂上方的压紧块，上述扭簧的第二臂沿安装板的左右方向平直设置，上述扭簧的第二臂端部向上延伸有与扭簧第二臂垂直设置的延伸臂，上述延伸臂为所述的弹性杆体，上述接触部为横杆，上述横杆与上述延伸臂的上端端部垂直设置，且上述横杆沿安装板的前后方向延伸设置。
上述弹簧为柱状弹簧，上述柱状弹簧沿安装板的上下方向延伸设置，上述柱状弹簧固定安装在文具壳体上，上述安装板上凸设有处于柱状弹簧的上端端部相对应设置的压块，上述柱状弹簧的下端端部向上延伸有延伸臂，上述延伸臂为所述的弹性杆体，上述接触部为横杆，上述横杆与上述延伸臂的上端端部垂直设置，且上述横杆沿安装板的前后方向延伸设置。
上述弹簧为柱状弹簧，上述柱状弹簧沿安装板的上下方向延伸设置，上述柱状弹簧固定安装在文具壳体上，上述安装板上凸设有处于柱状弹簧的上端端部相对应设置的压块，上述弹性杆体为沿安装板的上下方向延伸设置的塑胶弹骨，上述塑胶弹骨的下端端部固定于文具壳体上，上述塑胶弹骨的上端端部凸设有接触块，上述接触块为上述接触部，上述接触块上具有与第一斜面相配合接触的第一导向斜面和与第二斜面相配合接触的第二导向斜面。
上述弹簧为柱状弹簧，上述柱状弹簧处于上述安装板的下方，且上述柱状弹簧的两端端部均处于柱状弹簧的下端处，上述柱状弹簧的第一端端部与文具壳体固定配合，上述柱状弹簧的第二端端部向上延伸有延伸臂，上述延伸臂为所述的弹性杆体，上述接触部为横杆，上述横杆与上述延伸臂的上端端部垂直设置，且上述横杆沿安装板的前后方向延伸设置。
采用上述方案后，本发明一种按压式文具的按压结构，向下按压按钮时安装板的下移，安装板的下移使弹簧压缩，且限位块的第一斜面会与弹性杆体的接触部相接触，此时随着安装板的再次下移，接触部受第一斜面的影响使弹性杆体发生向左或向右变形，当接触部越过第一斜面时弹性杆体释放，弹性杆体向右或向左复位，同时放开手，弹簧复位，安装板上移，利用安装板的上移和弹性杆体的复位使接触部可落入至定位凹槽内并受定位凹槽一侧槽壁的限制而限固于定位凹槽内，安装板停止上移，此时安装板下端连接的部件即可呈固定状态伸出文具壳体外，同时，因第一斜面和第二斜面的下端共处于弹性杆体的一侧，即弹性杆体的左侧或右侧，第一斜面的上端和第二斜面的上端共处于弹性杆体的相对侧，即弹性杆体的右侧或左侧，使弹性杆体的中心轴线偏离定位凹槽的一侧，这样，接触部受定位凹槽槽壁的限固还呈一定向左或向右变形，并非呈完全复位状态；再次向下按压按钮时弹簧再次压缩，安装板的下移使接触部处于定位凹槽的上方，接触部释放，弹性杆体向右或向左完全复位，弹性杆体的完全复位使接触部相应处于第二斜面的上部上方，此时放开手，弹簧复位，安装板上移，安装板的上移，使接触部与第二斜面接触，并受第二斜面的斜度的影响使弹性杆体随安装板的上移而相应发生向右或向左变形，当接触部越过第二斜面的底部时，弹性杆体完全向左或向右释放，弹性杆体恢复回初始位置，安装板下端处的部件呈固定状态收缩回文具壳体内。与现有技术相比，利用弹性杆体、限位块和定位凹槽的位置关系使接触部在滑动轨道内的滑动只需靠弹性杆体的弹性即可实现，无需靠对滑动轨道内底面的磨擦才得以在滑动轨道内滑动，避免传统按压机构中因滑动轨道内底面的磨损而造成按压功能失效的问题，使用寿命长，按压寿命可达到500次以上，并在滑动轨道内无需设置任何导向台阶，使安装板的结构简易，易于成型；同时，接触部与限位块呈面与面接触，接触面积大，使限位块不易受接触部磨损。

具体实施方式
为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。
本发明的一种按压式文具的按压结构，实施例一，如图3、4所示，包括安装板1和弹性件，安装板1以移动的方式活动安装于文具壳体内，此文具壳体为修正带壳体200，此安装板1的安装方式与传统笔型修正带安装板的安装方式相同，在此不再累述，以修正带压嘴300的收缩方向为上下方向，安装板1的上端安装有其上部伸出修正带壳体200外的按钮400，安装板1的正面上端凹设有凹腔11，安装板1的正面位于此凹腔11内具有限位块12，该限位块12的外侧壁与凹腔11的内腔壁形成有一呈闭环形结构的滑动轨道，限位块12的顶面中部下凹有定位凹槽121。
本发明的创新之处在于：该限位块12具有处于限位块12左、右两侧的第一斜面122和第二斜面123，第一斜面122处于限位块12左侧，第二斜面处于限位块12右侧，第一斜面122呈向上倾斜的倾斜面，且第一斜面122上端处于第一斜面122下端的右侧，第二斜面123呈向上倾斜的倾斜面，第一斜面122的倾斜方向与第二斜面123的倾斜方向相同，该定位凹槽121处于第一斜面122的上端与第二斜面123的上端之间。
所述的弹性件包括有随安装板1的下移发生上下方向变形的弹簧2和随安装板1的下移发生左右方向变形的弹性杆体3，弹性杆体3沿上下方向竖立设置，第一斜面122的下端和第二斜面123的下端共处于弹性杆体3的左侧上方，第一斜面122的上端和第二斜面123的上端共处于弹性杆体3的右侧，即弹性杆体3的中心轴线处于定位凹槽121的左侧，弹性杆体3的上端端部具有处于滑动轨道内，并随安装板1的下移与第一斜面122或第二斜面123呈面与面滑动接触配合的接触部4，且弹性杆体3的中心轴线和第二斜面123的下部共处于定位凹槽121的左侧，第二斜面123的上部与定位凹槽121共处于弹性杆体3的中心轴线的右侧；优选的是：该弹簧2为扭簧，此扭簧固定安装在修正带壳体200的前侧内表面上，即修正带壳体200的前侧内表面上凸设有定位柱201，扭簧套装在定位柱201外，且扭簧的第一臂呈向上倾斜设置，也可呈向下倾斜设置，扭簧的第二臂沿安装板1的左右方向平直设置，且安装板1上凸设有压设在扭簧第一臂上的压紧块13，该扭簧的第二臂端部向上延伸有与扭簧第二臂垂直设置的延伸臂，此延伸臂即为所述的弹性杆体3，所述的接触部4为横杆，此横杆与延伸臂的上端端部垂直设置，且横杆沿安装板1的前后方向延伸设置。
所述的安装板1位于滑行轨道的顶面处向下凸设有朝向定位凹槽121的限位挡块14，限位挡块14呈V形结构，且限位挡块14的尖锐部处于定位凹槽121内。
本发明一种按压式文具的按压结构，当第一次向下按压按钮400时安装板1的下移，安装板1的下移使扭簧的第一臂受压紧块13的下移而受挤压发生变形，且限位块12的第一斜面122的下端会与接触部4呈面与面相接触，此时随着安装板1的再次下移，第一斜面122的上端会向下移，第一斜面122上端的下移使接触部4受向右挤压，弹性杆体3发生受右变形，第一斜面122的上端越过接触部4时，接触部4释放，弹性杆体3释放，弹性杆体3向左复位，弹性杆体3的向左复位时接触部4会受限位挡块14的限制而不再受左完全复位；同时放开按钮400，扭簧第一臂释放，扭簧第一臂向上复位，扭簧第一臂的向上复位推动安装板1向上移，安装板1的上移使接触部4与限位挡块14相分离，弹性杆体3继续向左复位，同时定位凹槽121上移至接触部4处，接触部4处于定位凹槽121内，并受定位凹槽121左槽壁的限制而被限制向左变形，限固于定位凹槽121内，并挂钩在定位凹槽121的槽底面上，安装板1被限制上移，此时安装板1下端安装的压嘴300呈固定状态伸出修正带壳体200外，同时，因弹性杆体的中心轴线处于定位凹槽的左侧，则弹性杆体3在定位凹槽121内时受定位凹槽左槽壁的限制还是呈向右受压的形态，并非呈完全向左复位状态；当第二次向下按压按钮400时扭簧第一臂再次被压缩，安装板1的下移，安装板1的下移使定位凹槽121处于接触部4的下方，接触部4释放，弹性杆体3继续向左至完全复位，接触部4处于第二斜面213的上部上方，此时放开按钮400，扭簧的第一臂复位，安装板1上移，安装板1的上移，使接触部4与第二斜面213接触，而第二斜面213呈向下倾斜的倾斜面，第二斜面213的上端处于第二斜面213下端的右侧，则随着安装板1的上移，接触部4受第二斜面213的下部向左挤压，弹性杆体3向左变形，当第二斜面213的下端处于接触部4的上方时，弹性杆体3释放向右复位，弹性杆体3的复位使接触部4恢复回初始位置，扭簧的第一臂顶持着安装板1，安装板1上的压嘴300呈固定状态收缩回修正带壳体200内。与现有技术相比，利用弹性杆体3、限位块12和定位凹槽121的位置关系使接触部4在滑动轨道内的滑动只需靠弹性杆体3的弹性即可实现，无需靠对滑动轨道内底面的磨擦才得以在滑动轨道内滑动，避免传统按压机构中因滑动轨道内底面的磨损而造成按压功能失效的问题，使用寿命长，按压寿命可达到500次以上，并在滑动轨道内无需设置任何导向台阶，使安装板的结构较为简易，易于成型，且对滑动轨道的内底面的磨损不会造成按压功能失效，同时，接触部4与限位块12和限位挡块14的接触均呈面与面的接触，接触面积大，使接触部4与限位块12及限位挡块14的相对磨损量较小，不会造成按压功能失效；另，通过限位挡块14可保证接触部4能够始终落入定位凹槽121内，防止弹性杆体3复位时接触部4直接越来定位凹槽121至第二斜面123处的问题，并通过限位挡块14的V形结构可对接触部4向定位凹槽121的移动起到导向作用。
本实施例的按压结构一般适用于按压式修正带上。
本发明的一种按压式文具的按压结构，实施例二，如图5所示，其与实施例一的区别仅在于弹簧的结构，具体如下：该弹簧为柱状弹簧5，修正带壳体的内表面上具有供柱状弹簧套固安装的安装柱，该柱状弹簧5沿安装板1的上下方向延伸设置，安装板1上相应固设有处于柱状弹簧5的上端端部的压块15，安装板1下移时压块15会压紧柱状弹簧5，其原理与压紧块对扭簧第一臂的压紧原理相同，该柱状弹簧5的下端端部向上延伸有延伸臂51，此延伸臂51即为所述的弹性杆体，接触部的结构与实施例一接触部的结构相同。此种结构的弹簧同理也可实现扭簧相同的功能，在此不再累述。
本实施例的按压结构一般适用于按压式修正带上。
本发明的一种按压式文具的按压结构，实施例三，如图6、7所示，其与实施例二的区别在于弹性杆体与接触部的结构，即弹簧也是为柱状弹簧5，具体区别是：该弹性杆体为沿安装板1的上下方向延伸设置的塑胶弹骨6，此塑胶弹簧6为由塑胶材质制作的杆体，利用塑胶特性可发生一定弹性形变，此塑胶弹骨6与柱状弹簧分体设置，塑胶弹骨6一体成型于修正带壳体200的内侧面，塑胶弹骨6的上端端部凸设有伸入滑动轨道内的接触块61，此接触块61即为实施例一所述的接触部，此接触块61的左侧处具有能与第一斜面212相贴配合接触的第一导向斜面611，接触块61的右侧下部处具有能与第二斜面213相贴配合接触的第二导向斜面612，此塑胶弹骨6与接触块61的配合也可实现实施例一中弹性杆体与接触部相同的功能，在此不再累述。
本实施例的按压结构一般适用于按压式修正带上。
本发明的一种按压式文具的按压结构，实施例四，如图8、9所示，其与实施例一的区别在于弹簧的安装方式，具体的是：弹簧也为柱状弹簧7，柱状弹簧7处于安装板1的下方，且柱状弹簧7的两端端部均处于柱状弹簧7的下端处，柱状弹簧7的第一端端部与文具壳体500固定配合，此文具壳体500的内壁上凸设有供柱状弹簧7的第一端端部固定勾挂的凸块（图中未示出），该柱状弹簧7的第二端端部向上延伸有延伸臂71，此延伸臂71为所述的弹性杆体，延伸臂的上端端部一体成型有与延伸臂相互垂直设置的，并沿安装板1的前后方向延伸设置的横杆72，此横杆72即为所述的接触部。此种结构的按压结构，如图10所示，其按钮向下按压时，安装板1下移，安装板1的下移直接将柱状弹簧7进行压缩，此柱状弹簧7的压缩方式与实施例一、二、三中弹簧的压缩方式不同，其余原理均相同，在此不再累述。
本实施例的按压结构一般适用于按压自动笔。
上述实施例和图式并非限定本发明的产品形态和式样，任何所属技术领域的普通技术人员对其所做的适当变化或修饰，皆应视为不脱离本发明的专利范畴。
