实施例3：
参见图5、6所示，本实施例提供的打印机机座3，主要包括：承载构件10、电机19、转动轮组件、胶辊25、张紧组件以及纸轴组件30。其连接关系以及工作原理如下：
承载构件10作为本打印机基座的主要部件的主要承载机构，其由水平承载架18、第一垂直安装架11、以及第二垂直安装架16构成。第一垂直安装架11、以及第二垂直安装架16分别位于水平承载架18的左右两边。
电机19用于带动用于向打印头传送打印纸的胶辊25旋转，该电机19固定在水平承载架18的顶面。
转动轮组件包括主动轮21以及从动轮22，其中主动轮21与电机19相互轴连接，主动轮21与从动轮22通过张紧皮带24连接，胶辊25压紧在打印头组件4的打印头104的顶部，用于向打印头104的下方传送打印纸，使胶辊25与从动轮22相互轴连接，在电机19的驱动下，电机19带动主动轮21旋转，主动轮21通过张紧皮带24带动从动轮22旋转，从动轮22带动与其轴连接的胶辊25旋转。
张紧组件主要用于防止张紧皮带24松动而影响主动轮21到从动轮22的动力传递，本实施例的张紧组件主要包括：滑块501、导杆28以及弹簧29。
在本实施例承载构件10的第一垂直安装架11的外侧立面还设置有一沿前后方向延伸的水平凹槽12，该水平凹槽12向第二垂直安装架16方向凹进，在安装时，首先捋弹簧29以及滑块501一前一后分别置入在该水平凹槽12内，使其并排，且弹簧29在该水平凹槽12内始终处于预定的被压缩状态， 然后捋导杆28从后端穿入该水平凹槽12，且分别贯穿弹簧29以及滑块501，拧紧该导杆28，即可捋弹簧29以及滑块501均固定在水平凹槽12内，且使弹簧29以及滑块501仅可在水平凹槽12内前后运动。
在滑块501位于第一垂直安装架11外的立面还设置有一可自转的张紧轮5011，使绕在从动轮22与从动轮22之间的张紧皮带24还绕过滑块501上的张紧轮5011，这样，在弹簧29对滑块501的张力作用下，张紧轮5011始终对皮带有向外拉伸的作用力，张紧皮带24始终保持张紧状态，从而确保主动轮21到从动轮22之间的动力传递，确保动力机构的性能稳固性。
纸轴组件30用于卷放打印纸，其固定在第一垂直安装架11、第二垂直安装架16之间，呈水平状地悬空于水平承载架18的上方，当打印时，卷在纸轴组件30上的打印纸从纸轴组件30出来，经过压紧在打印头104上的胶辊25，然后被传送至打印头组件4，具体是进入打印头104的下方在打印时，打印头在经过其下方的打印纸上进行打印操作，在打印纸上形成字迹。
由上可见，采用本实施例的技术方案，由于本实施例绕在主动轮21和从动轮22之间的张紧皮带24上还进一步绕过张紧组件上的张紧轮5011，从而可以确保张紧皮带24始终处于张紧状态，即使张紧皮带24由于使用损耗而导致其张力变化时，由于张紧组件上弹簧29对滑块501的张力作用，滑块501上的张紧轮5011对张紧皮带24的松紧度进行自适应的调整，确保张紧皮带24的张力始终保持一致，有利于提高打印机的性能的一致性以及保持性。
而在现有技术中，由于电机19、主动轮21、从动轮22以及胶辊25的安装均采用螺钉连接，在螺钉拧紧时不免存在定位误差，故在进行安装调试时既要顾及电机19的安装稳定性还要顾及张紧皮带24的张紧度，故在实际安装调节时需要通过反复调整安装才可以找到张紧的最佳状态，而采用本实施例技术方案，通过调整弹簧29的压缩程度，即可将张紧皮带24的张力自适应地调整达到要求的张力状态，其安装、调试更加精确、易于操作。
作为本实施例的示意，本实施例以电机19的转动轴位于第一垂直安装架11侧为例，在本实施例的第一垂直安装架11上还设置有一左右贯穿的孔部定位部13，在进行电机19安装时，使电机19的轴承20贯穿孔部定位部13，且使的轴承20的外周与孔部定位部13的内周相接触，在孔部定位部13对电机19的轴承20的限位下，电机19的轴承被孔部定位部13抱紧定位，不易于发生位移，由于确保电机19的工作稳定性，且安装操作简便。在捋电机19的轴承20贯穿孔部定位部13后，采用左右贯穿的螺钉捋电机19牢牢地固定在第一垂直安装架11上，且置放在水平承载架18上，电机19对水平承载架18有重力作用。
作为本实施例的示意，还可以在第一垂直安装架11上，以孔部定位部13为中心，对称地设置四个左右贯穿的定位螺孔14，且使该定位螺孔14具有一定的深度，且其深度大于定位孔部的深度。在进行电机19安装时，在捋电机19的轴承20置入孔部定位部13后，采用螺栓37左右贯穿电机19的端面以及定位螺孔14，从而将电机19牢牢地固定在第一垂直安装架11上，且由于定位螺孔14具有一定的深度，更能放置电机19左右前后水平疑问，故电机19的位置稳定性更持久，有利于确保打印机的性能一致性以及持久性。
作为本实施例的示意，还可以在第一垂直安装架11、第二垂直安装架16上还设置水平左右正对的两胶辊定位孔15，分别捋胶辊轴座401固定在该胶辊定位孔15上，在左右正对的两胶辊轴座401之间安装胶辊25，使位于第一垂直安装架11侧与胶辊25轴连接的从动轮22的转轴23贯穿在胶辊轴座401的中心孔部4011，使胶辊25可在中心孔部4011内自转。采用该结构，胶辊25的安装位置定位方便，更易于安装调试。
作为本实施例的示意，在本实施例中优选但不限于使纸轴组件30的安装位置高度高于胶辊25，譬如可以将胶辊定位孔15设置在第一垂直安装架11、第二垂直安装架16的底部，纸轴组件30位于其上前方，采用该设置由于可以顺着打印纸的重力作用与打印纸的传送方向一致，更有利于打印纸的传送，使传送更加顺畅，避免发生卡纸等现象。
参见图7所示，作为本实施例的示意，本实施例的打印机机座3还可以进一步包括用于向用户指示打印纸当前纸量的指示器组件。该指示器组件主要包括：指示器扣件38、指示器40以及弹簧43。
指示器扣件38设定在第二垂直安装架16与第一垂直安装架11相对的内侧。指示器40包括相互成一夹角的第一臂41、第二臂42。第一臂41的末端固定在指示器扣件38上伸出在第二垂直安装架16外侧的安装板39上，使指示器40位于第二垂直安装架16的外侧，第二臂42可沿第一臂41与指示器扣件38的安装板39的连接处旋转，在第一臂41与第二笔之间连接有弹簧43，弹簧43处于被压缩状态，在弹簧43的张力下，第二臂42的末端始终抵在装在承载构件10前端的纸轴组件30上的打印纸卷外，始终对打印纸卷有压力的作用，当打印纸卷逐渐变少时，第二臂42顺时针向下旋转。这样，可以在第二垂直安装架16的外端面上设置一定的刻度，用户可以观察指示器40当前的位置而了解的打印纸卷的纸量(即卷厚)。另外，在打印机外还可以设置一带刻度的观察窗，用户通过观察窗观察第二臂8022与刻度的对应位置，即可确定当前打印纸卷的纸量。
作为本实施例的示意，本实施例的打印机机座3还进一步包括导向板44， 该导向板44固定在第一垂直安装架11、第二垂直安装架16之间，且位于纸轴组件30与胶辊25之间，即导向板44的安装位置位于纸轴组件30下后方，位于胶辊25的上前方，使从纸轴组件30出来的打印纸绕过导向板44再到达胶辊25，以使导向板44作为纸轴组件30到胶辊25之间的打印纸传送导向部件，有利于打印纸的顺畅传送，避免卡纸。
作为本实施例的示意，本实施例的纸轴组件30采用以下结构构成，纸轴组件30主要包括：卷纸挡板45601、第一中心轴32、中心连接件33、扣板件34、弹簧35以及外轴36。
第一中心轴32的第一端部从卷纸挡板45601的中心孔部伸出且使第一中心轴32可沿在卷纸挡板45601的中心孔部内自由旋转。
扣板件34固定在第一垂直安装架11上，在扣板的一端部设置有两伸出块51、52，两伸出块51、52上分别设置有孔部，在两伸出块51、52之间间隔有一间隙，在安装时，捋第一中心轴32在第一端部的末端***扣板件34的间隙内，然后***一销钉53，使销钉53分别贯穿两伸出块51、52以及第一中心轴32，使扣板件34可以沿销钉53旋转，采用该结构更有利于方便扣板件与第一垂直安装架11以及第一中心轴的安装以及调试。
中心连接件33的第一端部与第一中心轴32的第二端部旋接，第二端部与弹簧35的第一端部连接，弹簧35的第二端抵触在第二垂直安装架16内侧的定位板17的凹位内，这样第一中心轴32、中心连接件33以及弹簧35构成一中心轴，该中心轴第一端固定在第一垂直安装架11、第二端为可连接在第二垂直安装架16上也可从第二垂直安装架16上去下的自由端。具体是，在安装时，可以通过压缩弹簧35将中心轴的第二端从第二垂直安装架16内侧的定位板17的定位凹位中移出而成为自由端，往中心轴的第二端处套入外轴36且使外轴36可以沿中心轴自由旋转，在外轴36上套入打印纸卷，然后压缩弹簧35将弹簧35的末端(即中心轴的第二端)移入第二垂直安装架16内侧的定位板17的定位凹位内，在弹簧35的张力作用下，中心轴的第二端牢牢地抵在定位凹位内，对定位凹位有向外的压力，此时中心轴牢牢地固定在第一垂直安装架11、第二垂直安装架16之间，打印纸卷套在外轴36上，且限位在卷纸挡板45601与第二垂直安装架16之间。采用该本实施例技术方案结构，由于采用中心轴、外轴36内外套装结构，可以避免打印纸卷对具有弹力机构的中心轴的摩擦损耗作用，有利于提高纸轴组件30的耐用性以及性能保持性。
作为本实施例的示意，优选但不限于使外轴36两端的外径相等且使两端的外径略大于中间段的外径，这样，当装上打印纸卷时，打印纸卷仅与外轴36的两端部段接触，而与外轴36的中间段不相接触，有利于减少打印纸卷 与外周之间的摩擦力，确保打印纸顺畅传送。
作为本实施例的示意，可以但不限于采用由钢质外轴36，有利于提高外轴36的光滑程度，进一步减少外轴36与打印纸卷的摩擦力，确保打印纸顺畅传送。
作为本实施例的示意，还可以但不限于选用钢质的定位板17，以提高该定位板17的耐用性。
作为本实施例的示意，本实施例的承载构件10优选但不限于采用水平承载架18、第一垂直安装架11、第二垂直安装架16一体化成型的构件，这样第一垂直安装架11、第二垂直安装架16的位置绝对固定而不存在由于采用钣金件相互铆接连接构成而由于部件之间的连接误差而导致第一垂直安装架11、第二垂直安装架16的相对位置偏移而导致电机固定位置不正对而存在安装误差等，采用本实施例技术方案可以确保固定在第一垂直安装架11、第二垂直安装架16之间的各部件的安装位置的精确度，有利于安装、调试。
作为本实施例的示意，本实施例的打印机机座3还包括：覆盖在承载构件10上的挡板45，挡板45用于覆盖承载构件10的顶部以及后端面以及第一垂直安装架11的前端面，以捋电机19、张紧组件、转动轮组件等关键的运动部件保护在挡板45内，避免灰尘落入，闭关呢对这些关键的运动部件起保护作用。
作为本实施例的示意，在挡板45上还可以设置有孔部，以有利于电机19散热。
作为本实施例的示意，还可以在本打印机机座3的第一垂直安装架11、第二垂直安装架16之间安装裁纸刀46，该裁纸刀46位于胶辊25的下方，用于供用户手动裁纸。其安装位置以及工作原理可以但不限于参见现有技术。
作为本实施例的示意，在第一垂直安装架11上位于孔部定位部13的内侧还设有一拉线张紧弹簧47，用于拉紧向电机19供电和经过该位置的其他部件的供电线或者控制线，避免导向对电机19的卷绕影响电机19工作。拉线张紧弹簧47的工作原理可以但不限于参见现有技术。
作为本实施例的示意，还可以在本实施例的纸轴组件30旁边安装一用于检测是否还有打印纸的传感器，该传感器可以设置在传感器安装板48上，以便在没有打印纸时，提醒用户加装打印纸。
作为本实施例的示意，在本实施例的打印机机座3的前端面，即承载构件10的前端面还覆盖有前盖板49，在该前盖板49上安装有方便用户操作的提手50。
上述结构的打印机机座3特别适用于要求结构紧凑的飞机用数据打印机，但也可以应用于其他的打印机。
实施例4：
参见图8、9所示，本实施例提供的打印头组件4，打印头组件4主要包括以下部件：调节板101、弹簧片102、安装板103、打印头104。其装配结构如下：
调节板101作为本打印头组件4的主要承载部件，用于安装弹簧片102、以及安装板103。在调节板101的顶面设置有一水平的凹槽1011，弹簧片102限位在凹槽1011内，弹簧片102的两端分别与凹槽1011的端部相抵触，凹槽1011对弹簧片102进行限位，禁止弹簧片102在水平方向发生左右、前后的运动。
本实施例的弹簧片102为一长条状，弹簧片102在中点位置被弯折，在中点处形成一大于零度小于180度的夹角a，夹角a的顶点即为弹簧片102的中点，弹簧片102始终处于微微被压缩状态。
本实施例的安装板103作为安装打印头104的安装框架，安装板103的前端与调节板101的前端铰链连接，使安装板103可以沿安装板103与调节板101之间的铰链连接部在垂直面内向上或者向下翻转，形成一可开合的合页结构。
在本实施例中，在安装板103的中部还设置有螺孔1030，该螺孔1030的中心与弹簧片102中点相对，在螺孔1030内固定有一螺钉1051，使螺钉1051穿过与夹角a的内侧相抵触，当在打印头104固定在安装板103顶部后，弹簧片102的中部的夹角a的顶点被打印头104覆盖，此时，在螺钉1051与打印头104的上下作用下，弹簧片102的顶点(即中点)被打印头104以及螺钉1051上下夹持，弹簧片102被固定在打印头104与安装板103之间，弹簧片102上的夹角a的顶点(中点)即为弹簧片102对打印头104的弹力支撑点，也是唯一的弹力支撑点。
本实施例的打印头104固定在安装板103顶面上，打印头104用于打印，其可以但不限于为热敏打印头104，热敏打印头104通过对位于打印头104下方的纸张的加热，使打印纸的局部发生碳化而在打印纸上形成字迹，实现打印。
本打印头组件4的工作原理是，当需要在打印头104进行打印时，位于打印头104顶面的、用于牵引打印纸的胶辊25向下紧压打印纸，使暂停向打印头104传送打印纸，此时胶辊25(参见图3、4中未画出，其设置以及结构可以但不限于参见实施例2以及现有技术)对打印头104有向下的压力，在胶辊25的压力左右下，打印头104向下运动，打印头104紧压在纸上打印数据。
在上述打印头104向下运动过程中，打印头104带动安装板103微微向 下翻转，打印头104以及安装板103对弹簧片102上夹角a的顶点施加向下的作用力，夹角a两边的弹簧片102被进一步压缩。
当当前行打印完成时，在被压缩的弹簧片102的弹力反作用力下，打印头104向上运动，安装板103向上微微翻转，胶辊往打印头104送纸；当送纸到预定位置时，再另胶辊向下压紧纸张，下压打印头104向下打印另一行，返回上述的循环，实现数据打印的多行连续。
由上可见，应用本实施例技术方案，由于本实施例的弹簧片102采用条状弹簧片102，且弹簧片102限位在调节板101的凹槽1011内，在凹槽1011的限位下，弹簧片102禁止在水平方向(包括左右前后方向)移动，可以确保弹簧片102位置的稳固性，避免因为弹簧片102水平位移而导致弹簧片102对打印头104的支撑力不均匀的问题。
并且，本实施例的弹簧片102的中点位置的夹角a的顶点被固定在打印头104以及安装板103之间，使与调节板101的凹槽1011底面构成等腰三角形状，以弹簧片102的夹角a的顶角作为支撑打印头104的唯一支撑点，使打印头104的弹力支撑位置唯一，且确保在弹簧片102被压缩以及回弹过程中的任一时刻夹角a两边的弹簧段的受力均始终保持一致、平衡，故能确保即使打印头组件4工作过程中，不会由于使用损耗而导致弹簧片102对打印头104的支撑力的位置变化，也不会由于因为夹角a两边弹簧片102由于受力不一而导致损耗不一致而导致弹簧片102对打印头104的支撑力不均匀导致打印头104倾斜等问题。
在实际的打印过程中上，如果弹簧片102对打印头104的支撑力不均匀的话，容易导致打印头104与纸的摩擦力不一致而导致打印纸走纸倾斜，打印痕迹深浅不一、字迹模糊等问题。
而本发明人在进行本发明研究过程中发现，现有技术采用四根弹簧片在打印头下方的四个位置支撑打印头，当各弹簧片的弹力相同的情况下，打印头可以四平八稳地保持平衡，而如果在打印过程中，四根弹簧片102中的任一或者部分或者发生损耗或者存在损坏不一，捋导致打印头104由于收到的支撑力不均匀而导致打印头倾斜的问题，故采用现有技术，容易出现纸的传送偏移以及打印痕迹深浅、打印字迹模糊等问题。
作为本实施例的示意，调节板101与安装板103之间还可以但不限于采用以下的铰链连接结构：
在调节板101的前端的左端设置有向上凸起的第一凸块1012、第二凸块1013，在第一凸块1012、第二凸块1013之间形成有第一间隙1014，在第一凸块1012、第二凸块1013上分别设置有水平左右正对的第一孔部1015；
在调节板101的前端的右端设置有向上凸起的第三凸块1016、第四凸块 1017，在第三凸块1016、第四凸块1017之间形成有第二间隙1018，在第三凸块1016、第四凸块1017上分别设置有水平左右正对的第二孔部1019；
在安装板103的前端的左端设置有向前方延伸凸起的第五凸块1031，在第五凸块1031中设置有第三孔部1032，在安装板103的前端的右端设置有向前方延伸凸起的第六凸块1033，在第六凸块1033中设置有第四孔部1034；
当调节板101与安装版103进行铰链连接时，使安装板103上的第五凸块1031嵌入在第一间隙1014中，且使第五凸块1031的宽度几乎等于第一间隙1014的宽度，即：使其与两边的第一凸块1012、第二凸块1013的相对的侧面相抵触而无法左右活动，然后***第一转轴1061，使第一转轴1061贯穿第一孔部1015、第三孔部1032。
同理，使安装板103上的第六凸块1033嵌入在第二间隙1018中，且使第六凸块1033的宽度几乎等于第二间隙1018的宽度，即：使其与两边的第一凸块1012、第二凸块1013的相对的面相抵触而无法左右活动，然后***第二转轴1062，使第二转轴1062顺次贯穿第三孔部1032、第四孔部1034。此时，安装板103可以沿在同一直线上的第一转轴1061、第二转轴1062在垂直面内翻转，进行合页运动。
采用上述铰链连接结构能够确保安装板103仅可以在垂直面内翻转(即进行合页运动)，而不会发生水平方向的位移，进一步避免由于安装板103的水平位移而导致弹簧中点位置变化而导致打印头104倾斜进而导致上述的纸走偏，导致打印痕迹深浅不一，以及打印字迹不清楚等问题。
作为本实施例的示意，还可以在安装板103的后端面上设置一向后端凸起的凸起定位部(图中未可见)；在调节板101上与安装板103后端面的相对垂直面上还相应一向后凹进的凹位10110，且使该凹位10110的高度大于安装板103后端的凸起定位部的高度。捋安装板103的前端与调节板101的前端铰链连接时，使安装板103后端面的凸起定位部限位在调节板101的凹位10110内，使安装板103翻转时，安装板103后端面(即合页运动的最外端)的凸起定位部始终限位在调节板101的凹位10110内，进而起到限制安装板103的合页翻转的的最高点以及最低点的作用。这样，即使由于设备故障或者人为失误而导致打印机受力过大，由于上述设置能够限制安装板103的翻转行程，确保打印头104以及安装板103不会由于打印头104的下压过度，而过度压缩弹簧片102，导致弹簧片102损耗过快或者损坏的问题，有利于提高打印头组件4的使用寿命。
作为本实施例的示意，在调节板101上还进一步设置有垂直上下贯穿的第五孔部10111、第六孔部10112。
在安装板103上与第五孔部10111、第六孔部10112上下正对位置还相 应设置有垂直贯穿的两螺孔1035，在打印头104的底面与第五孔部10111、第六孔部10112上下正对位置也设置有贯穿或者不贯穿的两螺孔1041(其中一个在图1中未可见)，且使第五孔部10111、第六孔部10112的内径大于安装板103以及打印头104上的螺孔1035、1041。分别使第一螺钉1052、第二螺钉1053贯穿调节板101的第一孔部1015、第二孔部1019，且第一螺钉1052、第二螺钉1053分别与安装板103以及打印头104上的螺孔1035、1041固定旋接拧紧，捋安装板103以及打印头104固定连接在一起。当安装板103沿其与调节板101的铰链连接部翻转时，第一螺钉1052、第二螺钉1053在第五孔部10111、第六孔部10112中***，不受第五孔部10111、第六孔部10112的限制。采用该结构有利于实现小体积的打印头组件4。
作为本实施例的示意，还可以在安装板103的前端设置相对水平相对的两垂直凸起块1036、1037，且使该两凸起块高于打印头104，以该两垂直凸起块1036、1037作为传送至打印头104的纸的边缘导向部，避免纸张走偏。
作为本实施例的示意，可以但不限于捋弹簧片102中部的夹角a设置为钝角(譬如为150度)。使弹簧片102对打印头104的支撑力较为平缓进一步有利于确保对打印头104的支撑稳定性。
作为本实施例的示意，参见图1所示，在本实施例中，在弹簧片102的两水平端部，使该水平末端弹簧片段1021相对靠近夹角a的弹簧段1022水平向上弯折一定角度，即水平末端弹簧片段1021与靠近夹角a的弹簧段1022形成一钝角。这样，弹簧片102与凹槽1011底面的为末端的弯折底面，有利于较少弹簧片102的水平摩擦力，避免弹簧片102位移，以及减少弹簧片102的磨损。
作为本实施例的示意，使弹簧片102两水平末端弹簧片段1021相对于凹槽1011的顶面呈锐角即可，而不需做太大的弯折。
作为本实施例的示意，参见图1、2所示，本实施例的调节板101由相互一体化成型的后盖板10113以及前端板10114组成。其中凹槽1011设置在前端板10114的顶面，且安装板103也固定在前端板10114上，
后盖板10113位于前端板10114的后段，呈“n”形凸起结构，且后盖板10113的顶面高于前端板10114的顶面。这样由后盖板10113到打印头104方向形成由高到低的变化，有利于向打印头104送纸。
另外，由上可见，采用本实施例技术方案，在打印以及送纸的过程中，仅作为打印关键部件的打印头组件4中的打印头104以及位于打印头104下方的安装板103以及弹簧片102运动，其他无需参加打印运动的附加部件静止，有利于提高打印头组件4的稳定性，且能够避免非必要部件连动而导致 结构松动，弹簧片102因为受力过大而导致失效等问题。
上述结构的打印头组件4特别适用于要求结构紧凑的飞机用数据打印机，但也可以应用于其他的打印机。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
