[0002] A door lock is a commonly used door security device to prevent unauthorized intrusion. It generally includes a lock body installed inside the door, a base for mounting the door lock handle, and a panel with the door lock handle mounted on it. When installing a door lock, the base is usually fixed to the door panel first, and then the panel with the door lock handle is installed and fixed to the base to achieve the installation of the door lock handle on the panel.

[0003] However, in actual use, during installation, one hand needs to hold the lock body steady to keep it level, while the other hand needs to tighten the screws. Because both hands need to perform different tasks at the same time, it is easy to cause inconvenience in operation. When multiple screws need to be handled at the same time, the lock body may shift during installation because it is impossible to keep both the stability of the lock body and the tightening of the screws at the same time. This can lead to inaccurate positioning, which in turn affects the installation quality and the final use effect of the door lock. Therefore, based on the above problems, a door lock that is easy to install has been developed. Utility Model Content

Block B515 is used to drive the insertion rod 516 to move. The outer wall of the slider B515 is fixedly connected to the insertion rod 516. The insertion rod 516 is used to insert into the protective cover 2 to achieve fixation. There are two sets of fixing mechanisms 5. The two sets of fixing mechanisms 5 are symmetrically arranged at the upper and lower ends of the outer wall of the panel 1. The outer wall of the slider B515 and the insertion rod 516 are slidably connected to the outer wall of the panel 1. The outer wall of the panel 1 has a slot, which provides sliding space for the slider B515 and the insertion rod 516. The protective cover 2 is inserted into the outer wall of the panel 1.

[0027] Working principle: A protective cover 2 is installed on the panel 1. A threaded post 412 is threadedly connected to the inner wall of the protective cover 2. A connecting mechanism 4 is set on the threaded post 412. When the door lock needs to be installed, the inner threaded ring 414 near the door handle 3 is first installed to the outer wall of the threaded post 412. Then, the installation tool is used to rotate the inner threaded ring 414, which has a socket. The tool is inserted into the socket and rotated to turn the inner threaded ring 414 to the top. The teeth of the outer wall of the inner threaded ring 414 are inserted into the tooth groove of the inner wall of the inner threaded block 411, thereby quickly limiting the multiple bolts 417. Then, when the bolts 417 are inserted into the door body, the nut 418 at the other end of the threaded post 412 is rotated to connect the nut 418 and the bolt 417. The nut 418 is rotated and connected to the outer wall of the connecting frame through the ball bearing 4111. Thus, the door lock can be installed quickly. The installation of the door lock can be completed by a single person.

[0028] Meanwhile, a fixing mechanism 5 is installed on panel 1. When the internal threaded ring 414 is rotated, the connecting rod A416 is driven to press down the slider. When the slider is squeezed, the connecting rod B514 on the outer wall of the connecting plate between the slider is pressed down. When the connecting rod B514 is squeezed, it squeezes the slider, thereby driving the insertion rod 516 at the top of the slider to insert into the top of the inner wall of the protective cover 2, thereby quickly fixing the protective cover 2 and thus protecting the connecting mechanism 4.
