Problems solved by technology

[0004] On the other hand, if figure 1 As shown, in the existing door lock box, in the state of inserting and locking the latch of the latch assembly, the front and rear width D of the door lock box 1 is greater than the thickness d of the lock bolt 2, therefore, indoors, When the outdoor air pressure changes or the wind blows, the door 3 will shake back and forth, and the lock bolt 2 will collide with the front end and the rear end of the lock box 1 and generate noise, which not only affects sleep, but also becomes a problem. Psychologically uneasy factors, and become the main factor for consumers to lose confidence in the quality of the door and the completion of the product
[0005] As the prior art related to the present invention, there is disclosed a lock box assembly having a variable bolt insertion portion of Patent Document 1, which can adjust the size of the bolt insertion portion inserted into the bolt and the bolt, thereby preventing the door from being damaged. Shaking, however, its structure requires structural elements such as an adjustment plate, an adjustment bolt, and a stopper, so that the structure becomes complicated and these parts need to be frequently installed
[0006] In addition, in the lock box for the push-pull door locking device of Patent Document 2, the lower curved surface is bent at about 70 to 80 degrees, and as long as the lock bolt protrudes from the built-in lock, it will continue to maintain the state of linear contact, thereby preventing the door from being locked. However, when the door is pushed or pulled in one direction, the latch slides along the sloped lower curved surface and the door may be opened
[0007] In addition, in the door lock striker box assembly for preventing door swaying in Patent Document 3, the striker box can be fixed at the optimal position even under repeated impacts. The position of the protrusion of the lock box cover changes the fastening position of the set screw in the transverse hole (slit) of the lock box, but this requires the lock box to have an additional housing, thereby not only increasing the cost, but also due to repeated Shock, the fastening position will change, resulting in a reduction in the effect of preventing the lock box from moving

Abstract

The present invention improves the cross-sectional shape of a striker so that a latch can be maintained in close contact with a striker while the latch is fitted to the striker without back-and-forthclearance, in order to solve the problem of a conventional striker, in which a door is shaken to make noise due to application of various external forces including changes in indoor and outdoor air pressure while a latch installed on the door is caught by a door striker installed on a door frame. The present invention comprises: a latch assembly provided on a side surface of a door (30), which isconnected to and operated by a handle member; and a striker (10), to which a latch (20) of the latch assembly is fitted, installed on a door frame (40), wherein the striker (10) has a front latching protrusion (12) for latching a front surface (22) of the latch (20) and a rear latching protrusion (14) for latching a rear surface (24) of the latch (20), wherein the front latching protrusion (12) iscomposed of a right-angled surface (12a) of a front end thereof and an inclined surface (12b) the inside thereof.

Description

technical field [0001] The invention relates to a door lock box. By improving the cross-sectional shape of the lock box, the invention can maintain a close contact state without back and forth play when the lock bolt is buckled into the lock box, so as to solve the problem of The existing lock box that produces sound when the door shakes due to the application of various external forces including changes in indoor and outdoor air pressure when the latch is locked to the door lock box installed on the door frame The problem. Background technique [0002] Usually, indoor doors or doors for entrances and exits are kept closed or have a lock function for safety or privacy protection. The door is provided with a handle part exposed to the front and back, and a handle part connected to the handle part is provided on the side of the door. A deadbolt assembly (also known as a "bolt pin" or "bolt lock") for a working locking appliance. [0003] In addition, the door frame is provid...
