A door threshold locator using the door defining base 100, as shown in fig. 3, includes the door defining base 100 and a positioning column 3 adapted to the door defining base 100, generally, the door defining base 100 is installed on a floor, the positioning column 3 is installed on a door leaf, and the positioning column 3 can move back and forth on a certain path relative to the door defining base 100 along with the door leaf. The positioning post 3 includes a post 31, and when the positioning post 3 moves close to the door restricting base 100, a lower end of the post 31 can contact the position restricting device 2. However, the arrangement of the column 31 is various, and one of them may be that the column 31 is fixed tightly, and the lower end of the column 31 needs to be determined according to the installation position of the positioning column 3; as in the present embodiment, the column 31 may be movably disposed on the positioning column 3 up and down. The positioning column 3 further comprises a positioning seat 32, the positioning seat 32 is provided with a column mounting through hole 321, the upper end of the column 31 penetrates through the column mounting through hole 321, and the lower end of the column 31 extends out of the lower part of the positioning seat 32. A spring 33 is further disposed in the cylinder mounting through hole 32, and the spring 33 is used for applying a downward spring force to the cylinder 31. The positioning post further comprises a stud 34, and the stud 34 is used for limiting the post body 31 not to fall out of the mounting through hole 321.

When the positioning post 3 carries the post 31 to move from the first elastic piece 21 to the free end 212, the lower end of the post 31 first contacts the high area portion 213, the first elastic piece 21 deforms downward under the pressing force of the post 31, and the post 31 can be pushed to move upward under the reaction force of the first elastic piece 21, so that the lower end of the post 31 can slide into the low area portion 214. After the cylinder 31 slides into the low area portion 214, the first resilient sheet 21 is restored upward under the elastic force, and the cylinder 31 is also moved downward under the action of the spring 33, so that the low area portion 214 and the lower end portion of the cylinder 31 are pressed together. On the other hand, when the cylinder 31 slides into the lower section 214 and enters the recessed section 12 of the bottom case 1, the left side wall 121, the right side wall 122, the lateral side wall 123 and the step 215 are arranged around the cylinder 31 to restrict the left, right, front and rear movements of the cylinder 31. At this time, the door-defining base 100 provides a good limit to the positioning post 3.

Further, when the positioning column 3 carries the column body 31 to move back, the high area portion 213 and the low area portion 214 on the first elastic sheet 21 form an obstacle that the step 215 can form the movement of the column body 31; since the step 215 is smoothly transited, when a large force is applied to the positioning column 3, the lower end of the cylinder 31 can push the first elastic sheet 21 to deform downward, so that the step 215 moves downward, and the cylinder 31 can slide out of the low area part 214 along the smooth transition surface across the step 215 and can leave the door-defining base 100 from the entrance side of the recessed area 12 along the inclined surface of the high area part 213. Therefore, the threshold positioner not only can realize a better threshold positioning function, but also can realize the purpose of releasing the limitation of the door only by simply pushing the door leaf when the door is opened.
