The present invention relates to a door lock, in particular to a lock structure that is mounted on a door body and can be easily changed to a left open or a right open to change the direction of the door lock handle as needed.

According to the general assembly, the door body can be divided into two different assembly types, left and right, depending on the space of the assembly space. In order to respond to such different assembly types, the handle of the door lock It must also be equipped with two different operating modes, left and right, to meet the needs of the application. However, since the traditional door locks are respectively designed to be fixed and dedicated for the left and right pulls of the handle, they cannot be used universally. As a result, the components must be opened separately, which increases the manufacturing cost and the inventory cost. Therefore, there is a kind of door lock handle such as the Republic of China Application No. 092214994 (Certificate No. M241473). The new patented method of changing the direction structure is mainly generated by the inner edge of the door lock housing being assembled with a handle shaft portion, and the two sides of the substrate are just opposite to the side wall of the door lock housing without being rotated, on the inner side of the substrate. The sleeve is further sleeved, and a bolt hole is arranged at a position below the substrate to lock a stopper plate, and the stopper plate is used to block the limit flap of the rotary sheet to obtain the handle control range. Limit, A sliding slot is further disposed on the upper edge of the bolt hole for the bolt to be locked, and the bolt is provided with a reduced diameter screw segment. When the bolt is loosened, the stopping plate is moved downward to be disengaged from the twisting gear. The stop limit type of the piece makes it possible to adjust the direction of operation of the change handle. After the adjustment is completed, the stop plate is re-locked and locked again. The limit function of the handle control range can be adjusted to adjust the handle operation direction, so that the conventional structure needs to be applied to the bolt hole of the stopper plate for the bolt to be locked. The edge is provided with a chute, and a reduced diameter screw segment is arranged on the bolt, so that the processing is not easy, and when the shifting handle is to be adjusted, the bolt is appropriately loosened so that the reduced diameter screw segment of the bolt accurately corresponds to the stopper bolt. The sliding groove extending from the upper edge of the hole is inconvenient to adjust the direction of the change, and a fin is disposed on the lower end of the hole, and the bottom plate is biased to be located on the side wall of the door lock casing, so that the substrate is not arbitrarily rotated. Therefore, the substrate cannot be applied to different sizes of the door lock case. Therefore, the manufacturer must mold different sizes of the substrate for different sizes of the door lock case, resulting in an increase in manufacturing cost and inventory cost.
