CN-224228392-U - Lock bolt structure and door bolt system

Abstract

The utility model provides a lock bolt structure and a door bolt system, and relates to the technical field of door bolt devices. The first limiting part and the second limiting part are respectively arranged at two opposite ends of the bolt body. The bolt seat defines a through groove, the bolt body penetrates through the through groove, and the bolt body is movably connected with the bolt seat. When the bolt body is in the first position, the first limiting part is clamped with the notch of the through groove, and the second limiting part extends towards the direction of the movable assembly to limit the door body. When the bolt is at the second position, the second limiting part is separated from the door body. The bolt body can move between the first position and the second position, and in order to release the locking of the door lock bolt structure, the movable component drives the second limiting part to shrink so as to be far away from the door body, and the door body can be freely opened after the second limiting part shrinks, so that the self-locking function of the door body is realized or released, and the use effect is further improved.

Description

Lock bolt structure and door bolt system Technical Field The utility model relates to the technical field of door bolt devices, in particular to a lock bolt structure and a door bolt system. Background A door bolt is a device for fixing a door body, and includes a door bolt body, a door bolt insertion hole, and the like. The main part of the door bolt is the door bolt body, and the door bolt body is rectangular or cylindrical in shape. The plug insertion hole is a portion of the plug body inserted into the door frame, and the plug body is generally made of metal, and has a certain hardness and durability. The common door bolt structure has the condition that the door bolt is opened and closed less conveniently, and the using effect of the door bolt is affected. Disclosure of utility model The utility model aims to provide a door lock bolt structure and a door bolt system, wherein a bolt body, a bolt seat and a movable component of the door lock bolt structure are matched to realize the function of opening and closing a door, and the door lock bolt structure is used for realizing the self-locking function or releasing the self-locking function of the door body, so that the door lock bolt structure is relatively simple to use. A first aspect of the present utility model provides a door latch structure comprising: The bolt body comprises a first limiting part and a second limiting part, and the first limiting part and the second limiting part are respectively arranged at two opposite ends of the bolt body; the bolt seat is used for limiting a through groove, the bolt body is arranged in the through groove in a penetrating mode, and the bolt body is movably connected with the bolt seat; the movable assembly is movably arranged on the door body; the bolt body is provided with at least a first position and a second position; When the bolt body is positioned at the first position, the first limiting part is clamped with the notch of the through groove, and the second limiting part extends towards the direction of the movable assembly to limit the door body; when the bolt body is positioned at the second position, the movable assembly is abutted with the second limiting part and drives the second limiting part to shrink, so that the second limiting part is separated from the door body. In one possible embodiment of the utility model, the second limiting part extends to form a bending part, and the bending angle of the bending part is theta, so that 45 degrees less than or equal to theta <90 degrees is satisfied.
