3 is a perspective view of a latch bolt protection structure 100 according to one embodiment of the present invention.

Referring to FIG. 3, the latch bolt protecting structure 100 may be provided on the door frame 20 to protect the latch bolt 12 formed on the motiis 11 of the door 10. As shown in FIG. Particularly, when the motors 11 and the strikers 110 are installed in the door 10 and the door frame 20 in a state where there is not yet been moved, (12) may be damaged. The latch bolt protecting structure 100 includes a latch bolt accommodating portion 120 installed in the door frame 20 and accommodating the latch bolt 12 to lock the door 10 and the door frame 20 And a latch bolt protector 130 which can be inserted into the latch bolt receiving portion 120 of the striker 110 and the striker 110. [ The latch bolt protector 130 is inserted into the latch bolt accommodating portion 120 to protect the latch bolt 12 in a state where the latch bolt protector 130 is not yet occupied, 120 so that the latch bolt accommodating portion 120 can play a normal role. According to the present embodiment, the latch bolt protector 130 can be easily detached from the latch bolt accommodating portion 120, so that an increase in the construction ratio can be minimized.

The specific configuration of the latch bolt protecting structure 100 and the latch bolt protecting device 130 will be described below.

The latching part 132 can be connected to a pushing member 133 which can be released by the latching of the latching part 132 and can be operated by the user. Specifically, when the user presses the pressing member 133, the latching portion 132 is spaced apart from the entrance side of the latch bolt accommodating portion 120, so that the latching state of the latching portion 132 can be released. The material between the engaging portion 132 and the rotation restricting portion 131 may have elasticity so that the shape of the engaging portion 132 is deformed by depressing the pressing member 133. [

5 is a horizontal sectional view of the latch bolt protection structure 100 according to one embodiment of the present invention.

5, when the latch bolt 12 is inserted into the latch bolt protecting structure 100, the upper and lower sides 12a and 12b of the latch bolt 12 are prevented from rotating by the rotation restricting portion 131 . Therefore, it is possible to prevent the latch bolt 12 from being engaged with the latch bolt receiving portion 120, thereby preventing the door 10 and the door frame 20 from being locked. Therefore, even when the worker frequently goes through the door 10, breakage of the latch bolt 12, which is generated in the process of forcibly separating the coupling between the latch bolt 12 and the latch bolt receiving portion 120, can be prevented . In addition, unlike the conventional latch bolt 12 protection method, there is no need for a separate member such as a cover, and a complicated construction procedure for installing the cover is not required.

The rotation restricting portion 131 may be formed to become narrower toward the inside of the latch bolt accommodating portion 120. More specifically, the shape of the horizontal cross section of the rotation restricting portion 131 may be triangular. With this configuration, it is possible to prevent the latch bolt 12 from rotating completely and engaging with the latch bolt receiving portion 120 of the striker 110. [

Since the latch bolt 12 is incompletely inserted into the rotation restricting portion 131, it is possible to prevent the door 10 Can be prevented from being opened by a small force. Thus, while the latch bolt 12 is protected, the door 10 can be kept to a minimum function.

6 is a horizontal sectional view of the state where the latch bolt protecting device 130 is removed.

Referring to FIG. 6, the latch bolt protector 130 can be removed from the latch bolt accommodating portion 120 immediately before completion of construction and just before entering or moving into the building. The user can easily remove the latch bolt protector 130 from the latch bolt accommodating portion 120 by simply pressing the pushing member 133. [ When the latch bolt protector 130 is removed, the latch bolt 12 is completely rotated and can be engaged with the latch bolt accommodating portion 120. Therefore, the door 10 and the door frame 20 can be locked.
