The invention relates to the technical field of security tools, and discloses a portable door stopper for an outward opening door. The portable door stopper comprises a base, rotary buckles are fixedly connected with both sides of the base, a threaded telescopic rod is arranged at the top end of the base, the top end of the base is in threaded connection with a telescopic cylinder through the threaded telescopic rod, a supporting arm is fixedly connected with the top end of the telescopic cylinder, a transverse piston movably sleeves the outer part of the top end of the supporting arm, and a suction cup piston cylinder movably sleeves one side of the transverse piston. The supporting arm is arranged to be of a rotatable structure, so that the supporting arm can play a role in inward opening and outward opening door types, when the door is opened outwards, the bottom of the supporting arm is obliquely turned to be close to one side of a user door, the pulling force for pulling the user door outwards is decomposed and utilized through the outwards-inclined supporting arm, the downward pressure of the base is increased, the frictional resistance between the base and the bottom surface is improved, and the door closing effect of the outward opening door can be reinforced by using the door stopper.
本发明涉及安防工具技术领域，且公开了一种外开门用便携阻门器，包括底座，所述底座的两侧固定连接有旋扣，所述底座的顶端设有螺纹伸缩杆，所述底座的顶端通过螺纹伸缩杆螺纹连接有伸缩筒，所述伸缩筒的顶端固定连接有支撑臂，所述支撑臂顶端的外部活动套接有横活塞，所述横活塞的一侧活动套接有吸盘活塞筒。本发明通过将支撑臂设置为可旋转结构，使其针对内开和外开两类门型均可发挥作用，在对外开门使用时，将支撑臂的底部倾斜转向靠近用户门的一侧，通过向外倾斜的支撑臂，将向外拉动用户门的拉力分解利用，以增大底座向下的压力，进而提高底座与底面的摩擦阻力，保证了外开门也可利用该阻门器进行加固闭门效果。
