The invention relates to a lifting apparatus for roof. The lifting apparatus comprises: an object placement mechanism; a support mechanism, wherein one end is hinged to the roof, and the other end ishinged to the object placement mechanism; when the object placement mechanism is suffered from an external force, the support mechanism can extend or shrink, so that the object placement mechanism approaches or leaves away from the roof; and a positioning mechanism comprising a positioning member and a connecting member matched with the positioning member, the positioning member being disposed onone of the roof and the object placement mechanism, and the connecting member being disposed on the other one of the roof and the object placement mechanism. When the positioning member is connected with the connecting member, the object placement mechanism is kept in a locked state relative to the roof; and when the connecting relation between the positioning member and the connecting member is released, the locked state between the object placement mechanism and the roof can be released. Therefore, the technical problems that a table is large in occupied space and the space cannot be effectively utilized in the prior art are solved.

    本发明涉及一种用于屋顶的吊装装置。吊装装置包括:置物机构;支撑机构,一端铰接于屋顶,另一端铰接于置物机构;当置物机构受到外力时,支撑机构能够伸展或收缩,以使置物机构靠近或者远离屋顶;以及定位机构,包括定位件和与定位件相适配的连接件,定位件设置于屋顶或者置物机构这两者中的一者上,连接件设置于屋顶或者置物机构这两者中的另一者上;当定位件与连接件相连时,置物机构相对于屋顶保持锁定状态;而当解除定位件与连接件的连接关系时,能够解除置物机构和屋顶之间的锁定状态。由此,解决了现有技术中的桌子存在的占位空间大、不能实现对空间有效利用的技术问题。
