Next, as shown in fig. 8, in the extended state of the stopper 200, the stopper body 21 is positioned rightward by the stopper spring to a position where the stopper protrusion 211 contacts the stopper 111, and the stopper 200 is stopped by the stopper 111 and cannot slide further rightward. At this point, the stop spring is also preferably in a compressed state, providing a rightward force to hold the stop 200 in that position. However, the force of the stop spring is now less than that shown in FIG. 2. It can also be seen that the return spring chamber 213 is enlarged relative to the state of fig. 2, i.e. the stop spring is somewhat extended.

Therefore, the using process of the flat-pull door shield comprises the following steps:

in a normal condition, it is in the state shown in fig. 8, that is, the stopper 200 slides to the extended position to prevent the door body from closing.

When the door needs to be closed, the stopper 200 is urged to slide to the state shown in fig. 2 when the door is opened. The bolt 131 can be retracted and locked spontaneously due to the corresponding guiding structure to form and maintain the state shown in fig. 2. Then, close the door body, when closing near the door body, reset button 141 is by the door frame effect and inwards retract to drive spring bolt 131 downward displacement, make the cooperation locking between spring bolt 131 and spacing protruding 211 remove, the door can normally close this moment, lock. When the door body is opened again, the stopper 200 spontaneously slides rightward by the stopper spring to form a door stopper operation state as shown in fig. 8.

Although the sliding door stop of the present embodiment is opened after closing the door, the sliding door stop is automatically switched to its working state, but the stop 200 may be locked in the state shown in fig. 2 if an additional constant locking structure is provided. This requires only a structure that locks the sliding movement of the stopper 200 relative to the base 100. For example, a set of cords is provided on the inner end of the base, which can be placed over the stopper in the state of fig. 2 to limit the sliding movement of the two.
