本便携式空压机采用了全包裹的壳体，使管道和仪表表盘之外的零部件均位于壳体内，不仅更为美观，由于壳体的外侧面更为规则，也便于运输和储存；本便携式空压机通过对壳体内储气罐、驱动电机、气缸组件、电池仓、进气管和出气管等零部件的位置进行设计，使本便携式空压机的整体结构更为紧凑，占地面积更小；本发明将质量较大的储气罐、驱动电机和气缸组件固定于壳体底部的安装板上，不仅能够起到更好的支撑作用，还能够避免安装储气罐、驱动电机和气缸组件时，直接在壳体的底部打孔，进一步增强了壳体底部的结构强度；同时储气罐、驱动电机和气缸组件三者均固定于安装板上也能够方便将 三者连通，使压缩后的气体能够更方便的进入到储气罐内；进一步的，电池仓设于储气罐的上方不仅能够合理利用储气罐上方的空间，还能够在不改变壳体体积的基础上尽可能的拉远电池仓和驱动电机、气缸组件的距离，避免驱动电机、气缸组件工作时产生的热量影响电池仓内电池的正常工作，有利于提高本便携式空压机工作时的稳定性；上述提手的设计便于搬运本便携式空压机。
在上述的一种便携式空压机中，所述驱动电机的上方设有调压阀、进气管和出气管，所述进气管和出气管的内端通过调压管连通，所述调压阀设于调压管的中部，所述进气管的内端连接有进气压力表，所述出气管的内端连接有出气压力表。
本便携式空压机将进气管、出气管、调压阀、调压管、进气压力表和出气压力表设于驱动电机和气缸组件的上方，充分利用了壳体内的剩余空间，使结构更加紧凑。
在上述的一种便携式空压机中，所述壳体的前侧面和上侧面之间设有斜面板，所述斜面板上设有进气安装孔、出气安装孔和旋钮安装孔，所述调压阀的调节旋钮设于旋钮安装孔内，所述进气压力表安装于进气安装孔内并倾斜于进气管设置，所述出气压力表安装于出气安装孔内并倾斜于出气管设置，所述壳体得前侧面上设有进气孔、出气孔和开关安装孔，所述进气管穿过进气孔，所述出气管穿过出气孔，所述开关安装孔内设有用于控制电源通断的开关按钮。
上述倾斜设置的斜面板能够使安装后的进气压力表与进气管以及出气压力表与出气管之间倾斜设置，安装时直接将进气压力表、出气压力表、进气管和出气管从后往前插入对应的孔位内即可，安装方便，还能够在调压管和前壳体 的内侧壁之间形成近似三角形的空间，有利于提高前壳体上端部的结构强度；同时，倾斜设置的进气压力表、出气压力表和调压旋钮也便于工作人员对观察进气端和出气端的压力以及对压力进行调节，操作更为方便；并且其调压阀的调节旋钮、进气压力表和出气压力表的表盘均从壳体前端部的外侧面伸出，符合用户的使用习惯，适应性较好。
在上述的一种便携式空压机中，所述壳体前侧面的中部向后凹陷形成前面板，所述壳体上侧面的中部向下凹陷形成上面板，所述前面板和上面板之间通过斜面板相连，所述进气孔、出气孔和开关安装孔均设于前面板上。
上述凹陷形成的上面板、斜面板和前面板能够使设于斜面板和前面板上的进气压力表、出气压力表、出气管和进气管的最外侧均位于壳体外侧壁的内侧，避免运输过程中或储存后上述进气压力表、出气压力表、出气管和进气管被误碰，有利于提高运输过程中或储存时的稳定性和安全性。
在上述的一种便携式空压机中，所述电池仓一体成型于壳体上端部的后侧，所述电池仓的后端开口，所述电池仓内可拆卸安装有用于安装电池包的电池安装座，所述壳体上设有将电池仓的开口封闭的电池盖；所述电池仓的前侧固定有用于安装控制器的控制支架。
电池仓直接成型于后壳体的上端，省去了安装电池仓的步骤，后续只需将电池包安装到电池仓内即可，有利于提高装配效率，并且相对于分体式的电池仓，直接成型的设计能够使电池仓与后壳体的连接更为牢固和稳定；可拆卸的电池安装座能够使本电池仓具有更好的适配性，能够安装不同型号的锂电池。
在上述的一种便携式空压机中，所述安装板由金属材料制成，所述安装 板的前后两侧均向上弯折形成弯折部，所述弯折部通过紧固件与壳体的侧壁和/或底壁固定连接。
上述安装板可以为铁板或铜板，不仅能够增强其结构强度，使之能够更好的支撑储气罐、驱动电机和气缸组件，还能够极大的增加固定于安装板上的储气罐、驱动电机和气缸组件的导热面积，增加两者的散热效率；弯折部上弯折部的设计不仅能够增强安装板前后两侧的结构强度，通过紧固件将安装板与壳体的侧壁和/或底壁固定连接，能够增强壳体底部的结构强度。
在上述的一种便携式空压机中，所述容置腔的前侧壁和底面连接处以及容置腔的后侧壁和底面连接处均沿左右方向间隔设置有加强板一，所述加强板一垂直于对应的容置腔前侧壁或容置腔后侧壁，所述加强板一的内侧设有与弯折部上边沿抵靠的台阶面。
上述加强板一的设计能够增强容置腔的前侧壁和底面连接处以及后侧壁和底面连接处的结构强度，避免在搬运过程中由于壳体底部上承重过大而导致在壳体底部的前后两侧发生弯折变型，提高本壳体工作时的稳定性和安全性；同时，由于安装板上固定的储气罐、驱动电机和气缸组件的质量较大，会导致安装板中部有下弹变形的趋势，而安装板的中部向下弹性变形势必会导致位于安装板前后两端的弯折部发生偏转，而台阶面与弯折部上边沿抵靠，能够避免弯折部相对加强板一发生偏转，从而降低了安装板中部弹性变形的可能性或者减少了安装板中部弹性变形的幅度，有利于进一步增强本壳体的结构强度。
在上述的一种便携式空压机中，所述容置腔的前侧壁上设有前加强筋，所述前加强筋的下端与加强板一的上端相连，所述容置腔的底面上设有底加 强筋，所述底加强筋的端部与加强板一的下端相连，所述电池仓的下侧面上沿左右方向间隔固定有加强板二，所述加强板二的外边沿与容置腔的后侧壁固定连接，所述加强板二的下端与对应的加强板一的上端相连。
上述前加强筋的设计能够增强壳体前壁的结构强度，所述底加强筋的设计能够增强壳体底壁的结构强度，其中，底加强筋还能够使底加强筋对安装板起到一个支撑作用，使安装板的下端面脱离容置腔的底面，储气罐、驱动电机和气缸组件通过螺钉或螺栓固定于安装板上，悬空的安装板为螺钉或螺栓的头部留下容置空间，避免螺钉或螺栓的头部与容置腔的底面直接抵靠导致安装板高低不均衡，从而影响安装板安装的稳定性以及壳体底部的结构强度；进一步的，安装板的下侧面与容置腔的底面之间具有间隙，能够增加安装板下侧面与空气的接触面积，有利于提高安装板的散热效率；上述加强板二的设计不仅能够对电池仓起到一个支撑的作用，还能够与储气罐的外形相适配，使储气罐安装后更为稳定，不容易发生晃动，同时，通过加强板一以及加强板二将储气罐固定后，还能够利用储气罐对壳体的结构进行反向支撑，避免壳体发生变形，有利提高本壳体的整体的结构强度。
在上述的一种便携式空压机中，所述安装板上设有用于支撑储气罐的安装支架，所述安装支架的上端设有与储气罐的外侧面配合的弧形部。
上述安装支架的设计能够使储气罐悬空，有助于扩大储气罐外侧壁与空气的接触面积，从而提高储气罐的散热效率；同时，金属材质的安装支架还能够起到导热作用，进一步提高了储气罐的散热效率，并且使储气罐悬空后也为储气罐的放水口处预留安装放水管的空间，使放水管能够有足够的长度安装阀门等部件。
在上述的一种便携式空压机中，所述容置腔底面的前端部的左右两侧以及容置腔底面的后端部的左右两侧均设有支撑孔，所述支撑孔内设有支撑脚，所述支撑脚的上端与安装板固定连接，所述支撑脚的下端凸出于壳体的下侧面。
上述支撑脚的设计能够使壳体的底壁悬空，使之不直接与地面接触，当地面有潮湿或有些微积水时，也不影响本便携式空压机的正常使用，有利于提高本便携式空压机的适应性。
在上述的一种便携式空压机中，所述壳体底壁的中部向上弯折形成安装部，所述支撑孔位于安装部的左右两侧，所述放水孔设于安装部的后端部。
上述安装部的设计能够抬高壳体底壁中部的高度，使安装部的下侧面与地面有足够的空间安装与放水管连接的排水管，也能够避免水直接从放水管排出时溅回壳体内部，同时，壳体底壁弯折后形成安装部的设计也能够在一定程度上增强壳体底壁的结构强度。
在上述的一种便携式空压机中，所述气缸组件包括箱体、缸套、活塞、阀板和缸盖，所述箱体的主体部的内端与驱动电机的端部连接，所述驱动电机的电机轴伸入主体部内并安装有曲轴和风叶，所述缸套安装于箱体的缸座部内，所述阀板和缸盖安装于缸座部和缸套的上端，所述活塞能够在连杆的驱动下在缸套内上下移动。
在上述的一种便携式空压机中，所述壳体包括前壳体和后壳体，所述前壳体和后壳体可拆卸安装，所述前壳体和后壳体的连接处分别设有卡槽和卡接凸起，所述卡槽和卡接凸起能够卡接固定。
本便携式空压机通过将原来一体式的壳体拆分成前壳体和后壳体，使本 便携式空压机在装配的时候可以先将部分零部件与对应的前壳体或后壳体固连，由于前壳体的后端和后壳体的前端开口，因此在装配过程中工人具有足够的操作空间，装配更为轻松和高效；然后再将装配好的前壳体和后壳体进行卡接组装，使装配更为简单，装配速度更快。
在上述的一种便携式空压机中，所述前壳体底板的中部设有向后凸出的插接部，所述后壳体底板的中部设有前端开口的插接槽，所述插接部能够从插接槽的开口处插入到插接槽内。
本分便携式空压机通过设置插接槽和插接部，使前壳体和后壳体在装配时更容易对准，降低装配难度；安装时，可以将安装板先放置于前壳体上，凸出的插接部能够起到更好的支撑作用，避免固定有储气罐、驱动电机和气缸组件的安装板向后倾倒，装配速度更快，装配的稳定性更高。
在上述的一种便携式空压机中，所述插接槽的左右槽壁之间的距离从后往前逐渐增大，所述插接部的形状与插接槽配合。
上述插接槽的左右槽壁之间的距离以及插接部的左右侧壁之间的距离从后往前逐渐增大的设计，便于两者进行插接配合，使插接部更容易插入插接槽内，有利于提高装配效率。
在上述的一种便携式空压机中，所述插接槽的左槽壁和右槽壁的下端均向内凸出有支撑凸条，所述插接部的左侧壁和右侧壁上均设有与对应支撑凸条配合的阶梯面；所述后壳体底板的上侧面上成型有两根限位凸条，两根限位凸条的前端部分别位于插接槽后端部的左右两侧，所述限位凸条前端部的内侧凸出于插接槽的左槽壁或右槽壁，所述限位凸条的前端设有导向面，所述导向面呈前高后低设置。
上述支撑凸条和阶梯面配合，不仅能够使装配后的前壳体和后壳体连接更为紧密，提高装配后整个壳体的结构强度；还能够在装配时，插接部伸入插接槽后，使插接部的阶梯面搭于支撑凸条上，即可完成定位，后续只需将前壳体和后壳体向内移动即可完成前壳体和后壳体的装配，能够在竖直方向对前壳体和后壳体的装配起到定位和限定作用，使装配更为简单快捷，有利于提高装配速度；由于前壳体的插接部是置于后壳体插接槽的支撑凸条上的，因此前壳体的部分重量会由插接槽周边的后壳体进行支撑，两根限位凸条的设计能够增强壳体的插接槽两侧的结构强度，防止后壳体变形；进一步的，导向面位于插接槽上方的限位凸条的前端，导向面的设计能够对插接部在插接过程中起到导向作用，使插接部能够顺利进入限位凸条和支撑凸条之间的插接槽内，其中，限位凸条的前端部只延伸到插接槽的后端部，该设计可以让前壳体和后壳体装配初期，插接部的后端先置于插接槽前端的支撑凸条上，然后在前壳体和后壳体逐渐接近的过程中，插接部的后端与导向面接触并沿导向面进入到限位凸条和支撑凸条之间，再持续移动并最终完成前壳体与后壳体的装配，结构简单，并能够使前壳体和后壳体的装配更为顺畅，有利于提高装配效率。
本便携式空压机的装配过程如下：先将储气罐、驱动电机和气缸组件固定于安装板上，并通过连接管将气缸组件的气缸出气口与储气罐的气罐进气口相连，将进气压力表、出气压力表、调节旋钮、进气管和出气管固定于前壳体对应的安装孔位上，将控制器固定于后壳体电池仓的前侧，并使电池仓的电池插片与控制器电连接，然后将提手以及装有储气罐、驱动电机和气缸组件的安装板放置于前壳体和后壳体之间，然后将前壳体和后壳体从安装板 的两侧向内移动将安装板容纳于前壳体和后壳体合围形成的容置腔内，将提手安装座容纳于前壳体和后壳体合围形成的安装腔内，然后通过紧固件将前壳体和后壳体固连，进一步的，通过紧固件将安装板与前壳体以及后壳体固连，接着在进气管和气缸组件的气缸进气口之间安装连接管，在储气罐的气罐出气口和出气管之间安装连接管，然后在壳体的左右两侧安装侧盖，最后安装电池仓的电池盖以及往电池舱内安装电池包，完成装配。
在上述的一种便携式空压机中，所述提手与壳体之间通过连接座和连接杆连接；所述连接座内设有中空的滑动腔，所述滑动腔的上部向内凸出形成限位凸台，所述连接杆的下部膨大形成限位部，所述限位部的直径大于限位凸台的内径，所述连接杆可移动安装于滑动腔内，所述连接杆可通过限位凸台伸出连接座并与提手可拆卸连接，在外力的作用下提手可带动连接杆上下移动。
上述连接座和连接杆的设计能够使提手在上拉时能够先滑动上移，使提手的下端与壳体的上端面之间有足够握持的空间，能够适应不同工人大小不同的手型。
在上述的一种便携式空压机中，所述限位凸台的上部向内凸出形成弹簧限位环，所述连接杆上套设有驱动连接杆下移的复位弹簧，所述复位弹簧的两端分别与限位部的上端面和弹簧限位环的下侧壁抵靠。
上述复位弹簧的设计能够在搬运结束后，使提手在复位弹簧的作用下恢复原位，减少竖向的高度，便于储存和搬运，使本便携式空压机的结构更为紧凑。
在上述的一种便携式空压机中，所述后壳体前侧面的上端部的左右两侧分别设有用于容纳连接座的后安装槽和用于容纳连接杆的后连接槽，所述前 壳体后侧面的上端部的左右两侧分别设有用于容纳连接座的前安装槽和用于容纳连接杆的前连接槽，所述前安装槽和后安装槽能够合围形成能够容纳且固定连接座的安装腔，所述前连接槽和后连接槽能够合围形成供连接杆穿过的连接孔。
上述前安装槽、后安装槽的设计便于对连接座进行定位，当前壳体和后壳体完成装配时，连接座即被固定于前安装槽和后安装槽围成的安装腔内，安装更为方便快捷；连接孔的设计不仅能够供连接杆穿过，还能够对连接座起到限位作用，从而通过安装座实现对提手的固定。
在上述的一种便携式空压机中，所述壳体包括侧盖，所述前壳体和后壳体的左右两侧均设有与侧盖配合的台阶部，所述侧盖与台阶部可拆卸安装；所述侧盖的内侧设有弹性卡件，所述前壳体和后壳体的台阶部上设有与弹性卡件配合的连接卡槽。

本便携式空压机采用了全包裹的壳体1，使管道和仪表表盘之外的零部件均位于壳体1内，不仅更为美观，由于壳体1的外侧面更为规则，也便于运输和储存；本便携式空压机通过对壳体1内储气罐101、驱动电机7、气缸组件8、电池仓11、进气管63和出气管64等零部件的位置进行设计，使本便携式空压机的整体结构更为紧凑，占地面积更小；本发明将质量较大的储气罐101、驱动电机7和气缸组件8固定于壳体1底部的安装板5上，不仅能够起到更好的支撑作用，还能够避免安装储气罐101、驱动电机7和气缸组件8时，直接在壳体1的底部打孔，进一步增强了壳体1底部的结构强度；同时储气罐101、驱动电机7和气缸组件8三者均固定于安装板5上也能够方便将三者连通，使压缩后的气体能够更方便的进入到储气罐101内；进一步的，电池仓11设于储气罐101的上方不仅能够合理 利用储气罐101上方的空间，还能够在不改变壳体1体积的基础上尽可能的拉远电池仓11和驱动电机7、气缸组件8的距离，避免驱动电机7、气缸组件8工作时产生的热量影响电池仓11内电池的正常工作，有利于提高本便携式空压机工作时的稳定性；上述提手4的设计便于搬运本便携式空压机。

如图12和图13所示，安装板5由金属材料制成，安装板5的前后两侧均向上弯折形成弯折部51，弯折部51通过紧固件与壳体1的侧壁和/或底壁固定连接；安装板5上设有用于支撑储气罐101的安装支架52，安装支架52的上端设有与储气罐101的外侧面配合的弧形部521。上述安装板5可以为铁板或铜板，不仅能够增强其结构强度，使之能够更好的支撑储气罐101、驱动电机7和气缸组件8，还 能够极大的增加固定于安装板5上的储气罐101、驱动电机7和气缸组件8的导热面积，增加两者的散热效率；弯折部51上弯折部51的设计不仅能够增强安装板5前后两侧的结构强度，通过紧固件将安装板5与壳体1的侧壁和/或底壁固定连接，能够增强壳体1底部的结构强度；上述安装支架52的设计能够使储气罐101悬空，有助于扩大储气罐101外侧壁与空气的接触面积，从而提高储气罐101的散热效率；同时，金属材质的安装支架52还能够起到导热作用，进一步提高了储气罐101的散热效率，并且使储气罐101悬空后也为储气罐101的放水口1013处预留安装放水管的空间，使放水管能够有足够的长度安装阀门等部件。
如图7和图8所示，容置腔12的前侧壁103和底面105连接处以及容置腔12的后侧壁104和底面105连接处均沿左右方向间隔设置有加强板一15，加强板一15垂直于对应的容置腔12前侧壁103或容置腔12后侧壁104，加强板一15的内侧设有与弯折部51上边沿抵靠的台阶面151；容置腔12的前侧壁103上设有前加强筋28，前加强筋28的下端与加强板一15的上端相连，容置腔12的底面105上设有底加强筋16，底加强筋16的端部与加强板一15的下端相连，电池仓11的下侧面上沿左右方向间隔固定有加强板二36，加强板二36的外边沿与容置腔12的后侧壁104固定连接，加强板二36的下端与对应的加强板一15的上端相连。
上述加强板一15的设计能够增强容置腔12的前侧壁103和底面105连接处以及后侧壁104和底面105连接处的结构强度，避免在搬运过程中由于壳体1底部上承重过大而导致在壳体1底部的前后两侧发生弯折变型，提高本壳体1工作时的稳定性和安全性；同时，由于安装板5上固定的储气罐101、驱动电机7和气缸组件8的质量较大，会导致安装板5中部有下弹变形的趋势，而安装板5的中部向下弹性变形势必会导致位于安装板5前后两端的弯折部51发生偏转，而台阶面151 与弯折部51上边沿抵靠，能够避免弯折部51相对加强板一15发生偏转，从而降低了安装板5中部弹性变形的可能性或者减少了安装板5中部弹性变形的幅度，有利于进一步增强本壳体1的结构强度；上述前加强筋28的设计能够增强壳体1前壁的结构强度，底加强筋16的设计能够增强壳体1底壁的结构强度，其中，底加强筋16还能够使底加强筋16对安装板5起到一个支撑作用，使安装板5的下端面脱离容置腔12的底面105，储气罐101、驱动电机7和气缸组件8通过螺钉或螺栓固定于安装板5上，悬空的安装板5为螺钉或螺栓的头部留下容置空间，避免螺钉或螺栓的头部与容置腔12的底面105直接抵靠导致安装板5高低不均衡，从而影响安装板5安装的稳定性以及壳体1底部的结构强度；进一步的，安装板5的下侧面与容置腔12的底面105之间具有间隙，能够增加安装板5下侧面与空气的接触面积，有利于提高安装板5的散热效率；上述加强板二36的设计不仅能够对电池仓11起到一个支撑的作用，还能够与储气罐101的外形相适配，使储气罐101安装后更为稳定，不容易发生晃动，同时，通过加强板一15以及加强板二36将储气罐101固定后，还能够利用储气罐101对壳体1的结构进行反向支撑，避免壳体1发生变形，有利提高本壳体1的整体的结构强度。
如图4、图7和图8所示，容置腔12底面105的前端部的左右两侧以及容置腔12底面105的后端部的左右两侧均设有支撑孔17，支撑孔17内设有支撑脚171，支撑脚171的上端与安装板5固定连接，支撑脚171的下端凸出于壳体1的下侧面；壳体1底壁的中部向上弯折形成安装部18，支撑孔17位于安装部18的左右两侧，放水孔181设于安装部18的后端部。上述支撑脚171的设计能够使壳体1的底壁悬空，使之不直接与地面接触，当地面有潮湿或有些微积水时，也不影响本便携式空压机的正常使用，有利于提高本便携式空压机的适应性；上述安装部18的 设计能够抬高壳体1底壁中部的高度，使安装部18的下侧面与地面有足够的空间安装与放水管连接的排水管，也能够避免水直接从放水管排出时溅回壳体1内部，同时，壳体1底壁弯折后形成安装部18的设计也能够在一定程度上增强壳体1底壁的结构强度。
如图18所示，气缸组件8包括箱体81、缸套82、活塞83、阀板84和缸盖85，箱体81的主体部811的内端与驱动电机7的端部连接，驱动电机7的电机轴71伸入主体部811内并安装有曲轴72和风叶74，缸套82安装于箱体81的缸座部812内，阀板84和缸盖85安装于缸座部812和缸套82的上端，活塞83能够在连杆73的驱动下在缸套82内上下移动。
如图2、图3、图7-9所示，壳体1包括前壳体21和后壳体31，前壳体21和后壳体31可拆卸安装，前壳体21和后壳体31的连接处分别设有卡槽31和卡接凸起24，卡槽31和卡接凸起24能够卡接固定；前壳体21底板的中部设有向后凸出的插接部25，后壳体31底板的中部设有前端开口的插接槽32，插接部25能够从插接槽32的开口处插入到插接槽32内。本便携式空压机通过将原来一体式的壳体1拆分成前壳体21和后壳体31，使本便携式空压机在装配的时候可以先将部分零部件与对应的前壳体21或后壳体31固连，由于前壳体21的后端和后壳体31的前端开口，因此在装配过程中工人具有足够的操作空间，装配更为轻松和高效；然后再将装配好的前壳体21和后壳体31进行卡接组装，使装配更为简单，装配速度更快；本分便携式空压机通过设置插接槽32和插接部25，使前壳体21和后壳体31在装配时更容易对准，降低装配难度；安装时，可以将安装板5先放置于前壳体21上，凸出的插接部25能够起到更好的支撑作用，避免固定有储气罐101、驱动电机7和气缸组件8的安装板5向后倾倒，装配速度更快，装配的稳定性更高。
如图14和图16所示，插接槽32的左右槽壁之间的距离从后往前逐渐增大，插接部25的形状与插接槽32配合；插接槽32的左槽壁和右槽壁的下端均向内凸出有支撑凸条321，插接部25的左侧壁和右侧壁上均设有与对应支撑凸条321配合的阶梯面251；后壳体31底板的上侧面上成型有两根限位凸条33，两根限位凸条33的前端部分别位于插接槽32后端部的左右两侧，限位凸条33前端部的内侧凸出于插接槽32的左槽壁或右槽壁，限位凸条33的前端设有导向面331，导向面331呈前高后低设置。
上述插接槽32的左右槽壁之间的距离以及插接部25的左右侧壁之间的距离从后往前逐渐增大的设计，便于两者进行插接配合，使插接部25更容易插入插接槽32内，有利于提高装配效率；上述支撑凸条321和阶梯面251配合，不仅能够使装配后的前壳体21和后壳体31连接更为紧密，提高装配后整个壳体1的结构强度；还能够在装配时，插接部25伸入插接槽32后，使插接部25的阶梯面251搭于支撑凸条321上，即可完成定位，后续只需将前壳体21和后壳体31向内移动即可完成前壳体21和后壳体31的装配，能够在竖直方向对前壳体21和后壳体31的装配起到定位和限定作用，使装配更为简单快捷，有利于提高装配速度；由于前壳体21的插接部25是置于后壳体31插接槽32的支撑凸条321上的，因此前壳体21的部分重量会由插接槽32周边的后壳体31进行支撑，两根限位凸条33的设计能够增强壳体1的插接槽32两侧的结构强度，防止后壳体31变形；进一步的，导向面331位于插接槽32上方的限位凸条33的前端，导向面331的设计能够对插接部25在插接过程中起到导向作用，使插接部25能够顺利进入限位凸条33和支撑凸条321之间的插接槽32内，其中，限位凸条33的前端部只延伸到插接槽32的后端部，该设计可以让前壳体21和后壳体31装配初期，插接部25的后端先置于插 接槽32前端的支撑凸条321上，然后在前壳体21和后壳体31逐渐接近的过程中，插接部25的后端与导向面331接触并沿导向面331进入到限位凸条33和支撑凸条321之间，再持续移动并最终完成前壳体21与后壳体31的装配，结构简单，并能够使前壳体21和后壳体31的装配更为顺畅，有利于提高装配效率。
本便携式空压机的装配过程如下：先将储气罐101、驱动电机7和气缸组件8固定于安装板5上，并通过连接管将气缸组件8的气缸出气口852与储气罐101的气罐进气口1011相连，将进气压力表621、出气压力表622、调节旋钮611、进气管63和出气管64固定于前壳体21对应的安装孔位上，将控制器固定于后壳体31电池仓11的前侧，并使电池仓11的电池插片与控制器电连接，然后将提手4以及装有储气罐101、驱动电机7和气缸组件8的安装板5放置于前壳体21和后壳体31之间，然后将前壳体21和后壳体31从安装板5的两侧向内移动将安装板5容纳于前壳体21和后壳体31合围形成的容置腔12内，将提手4安装座容纳于前壳体21和后壳体31合围形成的安装腔414内，然后通过紧固件将前壳体21和后壳体31固连，进一步的，通过紧固件将安装板5与前壳体21以及后壳体31固连，接着在进气管63和气缸组件8的气缸进气口851之间安装连接管，在储气罐101的气罐出气口1012和出气管64之间安装连接管，然后在壳体1的左右两侧安装侧盖13，最后安装电池仓11的电池盖113以及往电池舱内安装电池包112，完成装配。
如图1、图10和图15所示，提手4与壳体1之间通过连接座41和连接杆42连接；连接座41内设有中空的滑动腔411，滑动腔411的上部向内凸出形成限位凸台413，连接杆42的下部膨大形成限位部421，限位部421的直径大于限位凸台413的内径，连接杆42可移动安装于滑动腔411内，连接杆42可通过限位凸台413伸出连接座41并与提手4可拆卸连接，在外力的作用下提手4可带动连接杆42上下 移动；限位凸台413的上部向内凸出形成弹簧限位环431，连接杆42上套设有驱动连接杆42下移的复位弹簧43，复位弹簧43的两端分别与限位部421的上端面和弹簧限位环431的下侧壁抵靠。上述连接座41和连接杆42的设计能够使提手4在上拉时能够先滑动上移，使提手4的下端与壳体1的上端面之间有足够握持的空间，能够适应不同工人大小不同的手型；上述复位弹簧43的设计能够在搬运结束后，使提手4在复位弹簧43的作用下恢复原位，减少竖向的高度，便于储存和搬运，使本便携式空压机的结构更为紧凑。
进一步的，后壳体31前侧面的上端部的左右两侧分别设有用于容纳连接座41的后安装槽34和用于容纳连接杆42的后连接槽35，前壳体21后侧面的上端部的左右两侧分别设有用于容纳连接座41的前安装槽26和用于容纳连接杆42的前连接槽27，前安装槽26和后安装槽34能够合围形成能够容纳且固定连接座41的安装腔414，前连接槽27和后连接槽35能够合围形成供连接杆42穿过的连接孔412。上述前安装槽26、后安装槽34的设计便于对连接座41进行定位，当前壳体21和后壳体31完成装配时，连接座41即被固定于前安装槽26和后安装槽34围成的安装腔414内，安装更为方便快捷；连接孔412的设计不仅能够供连接杆42穿过，还能够对连接座41起到限位作用，从而通过安装座实现对提手4的固定。
如图1和图11所示，壳体1包括侧盖13，前壳体21和后壳体31的左右两侧均设有与侧盖13配合的台阶部14，侧盖13与台阶部14可拆卸安装；侧盖13的内侧设有弹性卡件131，前壳体21和后壳体31的台阶部14上设有与弹性卡件131配合的连接卡槽141。上述台阶部14的设计不仅能够增强前壳体21和后壳体31左右两侧的结构强度，还能够方便前壳体21和后壳体31两者与侧盖13相连，使连接更为简单快捷；上述弹性卡件131和连接卡槽141的设计能够增强侧盖13与前壳体 21以及后壳体31之间连接的稳定性。
