The invention discloses display equipment for a transportation tool. The display equipment structurally comprises a fixing device, a shell and a display screen, the upper side of the fixing device is attached to the lower side of the shell, the outer side of the display screen is fixedly connected with the front face of the shell in an embedded mode, and a pushing plate is fixed by a fixing cover to push an elastic plate, so that the bottom of an adsorber deforms to form suction force; according to the adsorber, a push rod moves rightwards under a limiting sleeve to push a lower pressing rod downwards, a jacking cover is extruded and compressed downwards under limiting of a fixing sleeve, negative pressure is formed through bouncing of a toughness belt, the adsorption capacity to a roof is improved, gaps formed by vehicle shaking to the roof lamp are reduced, when the arc-shaped cover is downwards extruded by the lower pressing rod, redundant gas is exhausted to the outer side through the sealing ring, when the gas is exhausted, the gas in the main body block pushes the one-way plate to compress the compression block, and then the compression block rebounds quickly to seal the main body block to prevent the gas from entering continuously, so that the adsorption speed of the top pressing cover to a car roof is increased; and damage caused by falling of the ceiling lamp is prevented.
本发明公开了一种用于交通运输工具的显示设备,其结构包括固定装置、外壳、显示屏,固定装置上侧与外壳下侧相贴合,显示屏外侧与外壳正面嵌固连接,推挤板在固定罩固定下推动弹板,使得吸附器底部产生形变形成吸力,吸附器是通过推杆在限位套下向右侧移动将下压杆向下推动,在固定套的限位下顶压罩被挤压向下压缩通过韧性带弹起形成负压,提高了对车顶的吸附能力,降低了车辆抖动对顶灯形成的缝隙,弧形盖被下压杆向下挤压时通过密封圈向外侧排出多余的气体,排出气体时主体块内部的气体推动单向板将压缩块压缩,随后压缩块迅速回弹对主体块进行密封防止气体继续进入,提高了顶压罩对车顶的吸附速度,防止了顶灯掉落造成损坏。
