Radiation-proof protective door
The anti-radiation protective door comprises a door frame, a door plate is slidably arranged in the door frame, a clamping groove is formed in the top of the door frame, a sliding groove is formed in the bottom of the door frame, the top of the door plate is slidably arranged in the clamping groove, a driving assembly is arranged in the clamping groove, rollers are rotatably arranged at the bottom of the door plate, and the rollers make contact with the bottom of the sliding groove; a rotating shaft is rotationally arranged in the sliding groove, a first horizontal groove, a first spiral groove, a second horizontal groove and a second spiral groove are formed in the periphery of the rotating shaft, and the first horizontal groove, the first spiral groove, the second horizontal groove and the second spiral groove sequentially communicate with one another, a protruding block is fixedly arranged at the bottom of the door plate, and a limiting rod is fixedly arranged on one side of the protruding block; the limiting rod is in sliding fit with the first horizontal groove, the first spiral groove, the second horizontal groove and the second spiral groove, and a cover plate is fixedly arranged on the rotating shaft. Dust, gravels and other foreign matters are prevented from falling into the sliding grooves due to access of related personnel, and meanwhile, the situation that abrasion of the pulley block is aggravated due to accumulation of the dust and the gravels is avoided.
本发明涉及一种防辐射防护门，包括门框，所述门框内滑动设置有门板，门框的顶部开设有卡槽，门框的底部开设有滑槽，门板的顶部滑动设置在卡槽内，卡槽内设置有驱动组件，门板的底部转动设置有滚轮，滚轮与滑槽的底部接触；滑槽转动设置有转轴，转轴的外周开设有第一水平槽、第一螺旋槽、第二水平槽和第二螺旋槽，且第一水平槽、第一螺旋槽、第二水平槽和第二螺旋槽依次连通，门板的底部固定设置有凸块，凸块的一侧固定设置有限位杆，限位杆与第一水平槽、第一螺旋槽、第二水平槽和第二螺旋槽滑动配合，转轴上固定设置有盖板。防止相关人员的出入将灰尘和砂石等异物掉落在滑槽内，同时避免灰尘和砂石的堆积加剧滑轮组的磨损。
