The connecting end 211 of the first elastic piece 21 (also the front end 221 of the second elastic piece 22) is located at the inlet side of the concave area 12, and the free end 212 of the first elastic piece 21 is located at the lateral side wall end of the lateral side wall 123 of the concave area 12.
As shown in fig. 1 to 3, in order to facilitate the installation of the limiting device 2, an installation channel 13 is provided between the upper wall 124 and the lower wall 125 of the bottom casing 1, the installation channel 13 is directly through the recessed area 12, during installation, two elastic pieces (21, 22) of the limiting device 2 are inserted into the recessed area 12 through the installation channel 13, the free end 212 of the first elastic piece 21 is stored and pressed under the storage part 11, and the front end 221 of the second elastic piece 22 (also the connection end 211 of the first elastic piece 21) is located at the inlet side of the recessed area 12 and is pressed against the bottom casing 1 at the position. In order to fix the limiting device 2 in the recessed area 12, a protrusion 14 is provided on the lower wall 125, and when the limiting device 2 is installed in the recessed area 12, the front end 221 of the second elastic piece 22 can elastically deform over the protrusion 14 and enter the recessed area 12, and the protrusion 14 can clamp the front end 221 of the second elastic piece 22 to prevent the limiting device 2 from being withdrawn. In this configuration, the free end 212 of the first spring piece 21 is pressed by the storage portion 11, and the stopper 2 can be positioned in the up-down direction. Naturally, the front end 221 of the second elastic piece 22 may be pried up when the limiting device 2 is to be taken out.
As shown in fig. 3, the threshold locator using the threshold fixing base 100 includes the threshold fixing base 100 and a positioning column 3 adapted to the threshold fixing base 100, generally, the threshold fixing base 100 is mounted on a floor, the positioning column 3 is mounted on a door leaf, and the positioning column 3 can move back and forth along a certain path relative to the threshold fixing base 100 along the door leaf. The positioning column 3 includes a column body 31, and when the positioning column 3 moves close to the threshold-defining base 100, the lower end portion of the column body 31 can contact with the limiting device 2. However, the arrangement mode of the column 31 is various, wherein one mode may be that the column 31 is fastened and fixed, 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 provided on the positioning column 3 so as to be movable up and down. The positioning column 3 further comprises a positioning seat body 32, a column body installation through hole 321 is formed in the positioning seat body 32, the upper end portion of the column body 31 is arranged in the column body installation through hole 321 in a penetrating mode, and the lower end portion of the column body 31 extends out to the lower portion of the positioning seat body 32. A spring 33 is further provided in the column mounting through hole 32, and the spring 33 is used for applying a downward spring force to the column 31. The positioning post further comprises a stud 34, and the stud 34 is used for limiting the post 31 not to fall out of the mounting through hole 321.
When the positioning post 3 moves from the first spring plate 21 to the free end 212 with the post 31, the lower end of the post 31 first contacts the high area 213, the first spring plate 21 deforms downward under the pressing force of the post 31, and conversely, the post 31 can be pushed upward under the reaction force of the first spring plate 21, so that the lower end of the post 31 can slide onto the low area 214. After the column 31 slides into the lower portion 214, the first elastic piece 21 returns upward under elastic force, and the column 31 also moves downward under the action of the spring 33, so that the lower portion 214 and the lower end of the column 31 are pressed together. On the other hand, when the column 31 slides onto the lower region 214, it enters the recessed region 12 of the bottom case 1, and the left side wall 121, the right side wall 122, the lateral side wall 123, and the step 215 are disposed around the column 31 so as to restrict the left, right, front, and rear movements of the column 31. At this time, the threshold-use base 100 provides a good limit for the positioning column 3.
Further, when the positioning column 3 moves back with the column 31, the high area 213 and the low area 214 of the first spring 21 form a step 215 to form an obstacle for the column 31 to move; since the step 215 is smoothly transited, when a large force is applied to the positioning column 3, the lower end portion of the column 31 can push the first elastic piece 21 to deform downward, so that the step 215 moves downward, and the column 31 can slide out of the low area 214 along a smooth transition surface over the step 215 and can leave the threshold-defining base 100 from the inlet side of the recessed area 12 along the inclined surface of the high area 213. Therefore, the threshold locator not only can realize a better threshold locating function, but also can release the limitation of the door by simply pushing the door leaf when the door is opened.
