The invention discloses a liquid crystal display advisement player for an elevator, and relates to the technical field of advisement players, the liquid crystal display advisement player comprises an advisement player body and a fixing frame, a clamping groove is formed in the fixing frame, and a connecting assembly is fixedly mounted on the rear side of the advisement player body; and the connecting assembly comprises a clamping block movably clamped in the clamping groove and mounting grooves formed in the left side and the right side of the interior of the clamping block, and a rotating rod is rotationally mounted in the clamping block. According to the advertising machine, the clamping blocks are correspondingly clamped into the inner sides of the clamping grooves to be flush, the sliding blocks located in the mounting grooves slide along the external threads by rotating the rotating rods, the sliding blocks move inwards to abut against the abutting blocks to move upwards to push the clamping columns to penetrate through the fixing frames and through holes in the clamping blocks for limiting, and therefore the advertising machine body is fixed; and the rotating rod is reversely rotated, so that the external thread outward-moving abutting block and the clamping column are pushed by the elastic force of the spring to move inwards to be separated from the through hole, the clamping block can be pulled out along the clamping groove, a user can conveniently disassemble the advertising machine body, and the maintenance efficiency is improved.
本发明公开了一种用于电梯的液晶显示广告机,涉及广告机技术领域,包括广告机本体和固定架,所述固定架的内部开设有卡槽,所述广告机本体的后侧固定安装有连接组件,所述连接组件包括有活动卡接于卡槽内部的卡块和开设于卡块内部左右两侧的安装槽,所述卡块的内部转动安装有转杆。本发明通过将卡块对应卡入卡槽的内侧平齐,通过转动转杆使位于安装槽内的滑块沿外螺纹滑动,通过滑块内移抵动抵块上移推动卡柱穿过固定架和卡块上的通孔进行限位从而对广告机本体进行固定,反向转动转杆使外螺纹外移抵块和卡柱受弹簧弹力推动内移脱出通孔即可沿卡槽将卡块抽出,从而便于使用者对广告机本体进行拆卸,提高了维护效率。
