Description

Technical Field

[0001] This application relates to the field of door locks, and particularly to a waterproof door lock. Background Art

[0002] A door lock is a common security device. After the door is locked, it can separate the inside and outside of the door. Especially traditional mechanical door locks usually consist of components such as a lock body, a lock tongue, a lock groove for accommodating the lock tongue, and a handle. Door locks are used in many scenarios, not only on room doors but also on car doors.

[0003] Generally, the lock body is provided with a handle groove for accommodating the handle. An opening communicating with the lock groove is directly formed in the handle groove. A dial on the rotating shaft passes through the opening and extends into the lock groove of the lock shell, and is in transmission connection with the lock tongue to drive the lock tongue to extend and retract.

[0004] Since the dial uses the rotation of the rotating shaft to drive the dial to swing, the opening of the lock body of this structure is larger than the swing formed by the dial. Whether the handle is in the open state or the closed state, in rainy weather, the relatively large opening is always likely to allow rainwater to penetrate. And since part of the position of the dial is located in the handle groove, it is also likely to be eroded by rainwater. Summary of the Invention

The lock case 13 is provided on the lock body 1 and located inside the door, that is, inside the lock body 1. The lock tongue 14 is slidably disposed within the lock case 13. A handle groove 11 is formed on the outer side of the lock body 1, and the handle 12 is installed in the handle groove 11 through a rotating shaft 2.

[0025] Referring to Figure 1 and Figure 2 , on the upper and lower sides of the lock case 13, there are provided paddles 15. The upper and lower ends of the rotating shaft 2 pass through the handle groove 11 and are connected to the upper and lower paddles 15. The lock case 13 is provided with a kidney-shaped groove 16. The other end of the paddle 15 is in transmission connection with the lock tongue 14 through this kidney-shaped groove 16. When the rotating shaft 2 (as shown in Figure 3 ) rotates, the paddle 15 can swing, so that the paddle 15 drives the lock tongue 14 to open or close.

[0026] The lock body 1 is further provided with a lock core 3. The lock core 3 penetrates from the outer side of the lock body 1 to the inner side of the lock body 1. A locking piece 31 is connected to the lock core 3 located inside the lock body 1, and the locking piece 31 can abut against the lock tongue 14. The lock body 1 can rotate the lock core 3 with a key to unlock or fix the lock tongue 14.

[0027] A linkage piece 4 is rotatably disposed inside the lock body 1. One end of the linkage piece 4 is in transmission connection with the lock tongue 14, and the other end is a locking end 41 for connecting a connecting rod. The connecting rod is used to connect a bolt to cooperate with the lock tongue 14 to achieve multi-point control. The connecting rod is perpendicular to the lock tongue 14. The bolts are located at the upper and lower ends of the door. The bolts and the connecting rod are not shown in the present application.

[0028] Referring to Figure 2 and Figure 3 , the handle groove 11 is in a ninety-degree "convex" shape. The rotating shaft 2 is rotatably disposed at the end position of the "convex" shape. The handle 12 is adapted to the handle groove 11 and is also in a "convex" shape. The handle 12 is connected to the rotating shaft 2.
