Locking mechanism for earthquake safety platform
The invention relates to the technical field of disaster prevention and self-rescue equipment, in particular to a locking mechanism for an earthquake safety platform. The locking mechanism comprises a safety cabin and a safety door hinged to one side of the safety cabin, the safety door is hinged to the safety cabin through a reset spring, the safety cabin is provided with a clamping groove matched with the safety door, the cross section of the clamping groove is in a concave shape, a guide pin is welded to the bottom, a blind hole matched with the guide pin is formed in the bottom of the safety cabin, wedge blocks are welded to the two ends of the clamping groove, stools are arranged at the bottoms of the two sides of the safety cabin, clamping blocks corresponding to the wedge blocks are arranged on one sides of the stools, stool legs are fixed to the lower sides of the stools, an observation window is formed in one side of the safety cabin, and an air hole is formed in the other side of the safety cabin. The safety door is quickly and effectively locked through embedding of the clamping groove and the safety door, meanwhile, locking is completed through the clamping blocks, the safety door is prevented from being easily opened due to external force, the safety of a user is fully guaranteed, and meanwhile the situation that the user can quickly open the safety cabin from the interior is ensured according to needs.
本发明涉及防灾自救设备技术领域，尤其涉及一种地震安全讲台用锁紧机构，包括安全舱及铰接在安全舱一侧的安全门，所述安全门通过复位弹簧与安全舱之间铰接，所述安全舱上设有与安全门适配的卡槽，所述卡槽横截面呈凹字形，且底部焊接有导向销，所述安全舱底部开设有与导向销适配的盲孔，所述卡槽两端焊接有楔块，所述安全舱两侧底部设有板凳，所述板凳一侧设有与楔块对应的卡块，所述板凳下侧固定有板凳脚，所述安全舱一侧开设有观测窗，所述安全舱另一侧开设有透气孔。本发明通过卡槽和安全门嵌合快速有效锁紧安全门，同时通过卡块完成锁死，避免受外力而被轻易打开，充分保障使用者安全，同时根据需要确保使用者能快速从内部打开安全舱。
