Description

基于科研项目成果展示用便于携带的宣讲装置 技术领域
本发明属于科研展示设备技术领域，特别是涉及基于科研项目成果展示用便于携带的宣讲装置。

科研项目管理是指课题从项目申请、立项论证、组织实施、检查评估、验收鉴定、成果申报、科技推广、档案入卷的全程管理。其目的是使科研项目实行制度化和科学化的管理，保证科研计划圆满完成，出成果、出人才、出效益，提高竞争力。
现有的科研项目成果的展示基本都是靠图纸展示或者研究的结果报告进行展示，结果报告中会有大量的专业术语，阅读研究结果报告的时候会比较生涩难懂，当科研项目成果向大众展示的时候不生动，并且成果需要向多人展示的时候，结果报告就需要多份打印浪费资源，或者传递的过程会产生损坏，另一方面现有的展示报告在展示栏展示的时候需要用胶带粘贴不能及时的跟换或者在展示栏残留有印记不美观，为了向外界提供科研项目成果，常常会使用一种展示设备来将成果进行展出。
经检索，公告号CN112545259A，公告日期2021-03-26公开了一种科研项目管理用成果展示设备，包括展示柜，所述展示柜的一端活动连接有柜板，且柜板的前后两端均安装有玻璃，所述展示柜的两侧柜壁之间连接有两个放置板，所述展示柜的一端连接有凸起，所述凸起的两端共同连接有升降装置，所述升降装置的下端连接有支撑板，所 述支撑板的下端连接有转向防滑箱，且转向防滑箱的一端活动连接有盖板，所述转向防滑箱的下端连接有四个成矩形阵列分布的万向轮。本发明操作简便，通过设置的转向防滑箱，可避免该设备在工作过程中出现易滑动的情况，使得整个设备在工作时更加稳定，同时也便于该设备进行多角度展示成果，而所设置的升降装置，可便于不同身高的人观看展示柜内的成果。
