Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 1 and 2, the latch bolt assembly A for a moti-lock according to the present invention includes a support block 10 and an upper head and a lower head 20. As shown in Fig.

The support block 10 is coupled to the housing 100 of the motis lock.

The protruding portion 11 is integrally formed on the front upper and lower surfaces of the support block 10.

It is possible to form a separate supporting means by integrally forming the protruding portion 11 on the front upper and lower surfaces of the supporting block 10 so that the support of the upper head and the lower head 20 can be formed through the protruding portion 11 .

At this time, the projecting portion 11 of the support block 10 is preferably cylindrical.

The protrusion 11 of the support block 10 has a cylindrical shape so that there is no angled portion on the outer circumferential surface of the protrusion 11 so that the insertion of the protrusion 11 into the through hole 21 formed in the upper and lower heads 20 So that it can be easily performed.

On the other hand, the support block 10 flows back and forth in the housing 100 of the moti-lock.

At this time, the forward and backward flow of the support block 10 may be made in any conventional structure and manner, but the detailed description about the forward and backward flow of the support block 10 is omitted.

The upper head and the lower head 20 can be inserted into the insertion groove of the door frame.

A through hole 21 is formed in the rear of the upper head and the lower head 20.

The through hole 21 is formed in the rear of the upper head and the lower head 20 so that the upper head and the lower head 20 are inserted into the supporting block 10 as the protruding portion 11 of the supporting block 10 is inserted into the through- 10).

At this time, it is preferable that the through holes 21 of the upper head and the lower head 20 are circular.

The outer circumferential surface of the protruding portion 11 of the support block 10 in a cylindrical shape is brought into close contact with the inner circumferential surface of the through hole 21 by making the through hole 21 of the upper head and the lower head 20 circular, The flow of the head 20 can be prevented.

The assembling of the latch bolt assembly A for a moti-lock according to the present invention as described above will be described in detail as follows.

In the present invention, protrusions 11 are integrally formed on the top and bottom surfaces of the support block 10 which is coupled to the housing 100 of the motis lock.

Therefore, when the protruding portion 11 of the support block 10 is inserted into the through-hole 21 of the upper head and the lower head 20, The upper head and the lower head 20 can be simply coupled to the support block 10 without the support means of the support block 10 being connected.

Thus, the upper head and the lower head 20 can be simply coupled to the support block 10 without having to attach separate support means for supporting the upper head and the lower head 20 on the support block 10 It is possible to simplify the manufacturing and assembling of the latch bolt since the manufacturing of the separate supporting means and the assembling process of the supporting block 10 and the supporting means can be omitted.

At this time, the projecting portion 11 formed in the support block 10 of the present invention is cylindrical.

The through holes 21 formed in the upper head and lower head 20 of the present invention are circular.
