Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and in particular to an assembled rod-shaped door lock and an access door. Background Technology

[0002] Rod-shaped door lock devices are mostly used in access doors with protective covers. They generally include a rod, a latch, and a handle. During assembly, the rod is first vertically and rotatably installed inside the access door, with a latch welded to both ends. Simultaneously, the handle is swung and installed on the outside of the access door, welded to the middle of the rod, with the handle's pivot coaxial with the rod. While the above-mentioned rod-shaped door lock device has a simple structure and low cost, it suffers from the following drawbacks, leading to inconvenience in use and maintenance: 1. The various components of the rod-shaped door lock are fixed by welding. When the rod-shaped door lock is damaged, it is difficult to disassemble the entire device. Alternatively, when individual components are damaged, they cannot be replaced due to the overall welding; the entire rod-shaped door lock must be cut and replaced. 2. The rod-shaped door lock is one-to-one matched with the size of the access door, making it unsuitable for other sizes of access doors, resulting in low flexibility. Therefore, this utility model provides a new rod-shaped door lock structure that solves the above technical problems. Utility Model Content

There are two connecting rods, which are respectively assembled at both ends of the main rod to extend the main rod. An adjustment and mounting structure is provided between the connecting rod and the main rod. The connecting rod and the main rod are adjusted and fixed together by adjusting the overall length of the rod-shaped door lock through the adjustment and mounting structure. Alternatively, the main rod can be fixedly assembled with connecting rods of different lengths through the adjustment and mounting structure, thus providing a high degree of flexibility.

[0005] The latch is installed at the end of the connecting rod away from the main rod and can engage with the lock hole pre-rotated in the door frame.

[0006] One end of the handle is installed in the middle of the main rod, and the main rod serves as the pivot. The user can rotate the main rod and connecting rod by flipping the handle, thereby causing the locking tongue to engage / disengage from the lock hole.

[0012] Preferably, the end of the handle is provided with a through hole, the handle is sleeved on the middle of the main rod through the through hole and locked with screws, the structure is simple and detachable, and it is convenient for maintenance and disassembly.

[0013] Preferably, the assembled rod-shaped door lock further includes a sleeve seat, there are two sleeve seats, which are rotatably sleeved on the two connecting rods respectively. The seat body of the sleeve seat is provided with a mounting hole and is locked in the position to be installed by screws, which can prevent the end of the connecting rod away from the main rod from twisting or tilting.

[0014] Preferably, the assembled rod-shaped door lock also includes a handle box, one end of which is provided with a through hole and is fitted onto the middle of the main rod. The handle is stored inside the handle box to prevent accidental contact.

[0015] Preferably, the end of the handle furthest from the main rod is provided with a pull hole, making it convenient for the user to pull out the handle.
