However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0020] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] This embodiment provides an internal latch structure for a door lock. This latch structure is simple in structure and can directly install the spring inside the latch structure, avoiding the need to directly install the spring on the door lock. This simplifies the operation steps, improves the installation efficiency of the latch structure, and further enhances the installation stability of the latch structure.

[0022] Combination Figures 1 to 3 As shown, the internal latch structure of the door lock in this embodiment includes a mounting member 10 and a locking part 20. The mounting member 10 is installed inside the door lock, while the locking part 20 is disposed inside the mounting member 10, and cooperates with the mounting member 10 to form a latch structure for locking the door lock.

[0023] In this embodiment, the mounting component 10 is provided with a first cavity 11 and a second cavity 12. There are two second cavities 12, which are symmetrically arranged about the first cavity 11. With the cooperation of the first cavity 11 and the second cavity 12, the locking part 20 is installed, avoiding the locking part 20 from being directly installed in the door lock, thus simplifying the installation steps.

[0024] Combination Figure 2 and Figure 3 As shown, the locking part 20 of this embodiment includes a locking block 21, a locking spring 22, and a locking ball 23. The locking block 21 is located in the first cavity 11 and rotates to lock the door. The locking spring 22 is located in the second cavity 12. The locking ball 23 is located at the end of the locking spring 22 near the locking block 21 and is fixedly connected to the end of the locking spring 22. When the locking block 21 rotates, the locking ball 23 extends and retracts under the action of the locking spring 22. In this embodiment, there are two locking springs 22, which are located in the corresponding second cavities 12. When the door lock is locked, the locking block 21 rotates. Under the combined action of the locking spring 22 and the locking ball 23, the locking block 21 is limited, thereby realizing the locking operation of the door lock.

[0025] Specifically, in this embodiment, the locking block 21 is a cylindrical structure. The edge of the locking block 21 is provided with a plurality of locking protrusions 211. The locking protrusions 211 are evenly distributed along the edge of the locking block 21, and a slot is formed between adjacent locking protrusions 211. The locking ball 23 is located in the slot. When the locking block 21 rotates, the locking ball 23 switches between the slots to lock the door. During the rotation of the locking block 21, the slots will correspond to the locking ball 23 in sequence, thereby realizing the switching of the locking ball 23 between adjacent slots to realize the locking operation of the door.

[0026] In this embodiment, the mounting component 10 is provided with a third cavity 13. There are two third cavities 13, which are symmetrically arranged about the first cavity 11. A prompting part 30 is provided in the third cavity 13. The prompting part 30 includes a prompting spring 31 and a prompting protrusion 32. The prompting protrusion 32 is located at the end of the prompting spring 31 and is fixedly connected to the prompting spring 31. When the locking block 21 rotates to lock the door, the prompting protrusion 32 emits a sound. The presence of the prompting part 30 can prompt the door to be locked. When a sound is emitted, it indicates that the locking structure has been completed.

[0027] In actual use, the locking spring 22 of the locking part 20 is installed inside the mounting part 10, thereby effectively avoiding the need for early installation of the locking spring 22. The locking block 21 of the locking part 20 cooperates with the locking spring 22 and the locking ball 23 to realize the quick locking of the door lock. The presence of the prompting part 30 can emit a prompting sound. After the prompting sound is emitted, it indicates that the locking structure has completed locking.

[0028] In summary, the latch structure of this embodiment is simple and can directly install the spring inside the latch structure, avoiding the need to directly install the spring on the door lock. This simplifies the operation steps, improves the installation efficiency of the latch structure, and further enhances the installation stability of the latch structure.
