[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The following describes an embodiment of this utility model based on its overall structure.

[0024] like Figures 1 to 4 As shown, this utility model provides a door lock switch device. The front end face of the lower shell 1 is fixedly provided with a door 2. The upper rear side of the door 2 is fixedly provided with a snap plate 10 for fixing. The inside of the door 2 is slidably provided with a snap 6 for fixing. The rear end face of the door 2 is fixedly provided with an exterior pressure plate 9, and the interior of the exterior pressure plate 9 is in contact with the rear side of the snap plate 10.

[0025] The snap-on pressure plate 10 has screw holes 7 inside all four sides of its rear end face for internal fixing. Screws 8 are installed inside the screw holes 7 for fixing. Hollow threaded posts 18 are fixed around the upper rear side of the compartment door 2, and screws 8 are inserted into the hollow threaded posts 18. Springs 5 ​​are fixed on the lower left and right sides of the snap 6 for buffering and reset. The lower side of the springs 5 ​​is fixed to the upper rear side of the compartment door 2.

[0026] The upper end of the snap-on pressure plate 10 has a groove 17 in the middle, and the snap 6 is fixed inside the groove 17. The lower end of the compartment door 2 has concave columns 4 fixed on both the left and right sides, and the lower side of the concave columns 4 has a rotating hardware shaft 3.

[0027] The outer side of the metal shaft 3 has a circular groove 15 inside, which serves to fix the shaft inside the groove. The circular groove 15 has inner grooves 16 on both the front and rear sides.

[0028] A frustum 13 is slidably provided inside the circular groove 15, and a long rod 11 is fixedly provided in the middle of the outer side of the frustum 13 for fixing.

[0029] A short column 12 is fixedly provided on the outer side of the rear end of the long rod 11. Columns 14 are fixed on both the upper and lower sides of the truncated cone 13 to play a fixing role, and the columns 14 fit inside the inner groove 16.

[0030] The working principle and process of a door lock switch device: The door lock switch device mainly consists of a lower shell 1, a door 2, a snap-on pressure plate 10, a snap 6, an outer pressure plate 9, screws 8, springs 5, and a hardware shaft 3. The door 2 is connected to the external structure via the hardware shaft 3. The snap 6 and other components are used to control the opening and closing of the door 2. When the snap 6 is pressed, its upper side is located inside the groove 17 in the middle of the upper end of the snap-on pressure plate 10. When the door 2 needs to be opened, the snap 6 is pressed inward towards the door 2. Since springs 5 ​​are fixed on the left and right sides of the lower end of the snap 6, and the lower side of the springs 5 ​​is fixed to the upper rear side of the door 2, pressing the snap 6 will compress the springs 5, causing elastic deformation and storing elastic potential energy. After the snap 6 is pressed, its position will change, releasing the door 2 from being closed. When the door is locked, it is no longer restricted by the snap 6 and can be opened. The door opens by rotating around the metal pivot 3. Concave posts 4 are fixed on the lower left and right sides of the door. The metal pivot 3 is rotatably mounted on the upper left and right sides of the rear end of the lower shell 1, with the upper side of the metal pivot 3 fitting against the lower side of the concave posts 4. After the snap 6 is unlocked, the door can rotate around the metal pivot 3, thus opening the door. Manually rotating the door around the metal pivot 3 moves it towards the closing direction until the door is fitted against the upper side of the rear end face of the lower shell 1. When the door moves to the closed position, the snap 6 returns to its initial position under the elastic restoring force of the spring 5, and the snap 6 re-locks the door. The snap-on plate 10 is used to keep the door 2 closed. The screw 8 engages with the screw hole 7 and the hollow threaded post 18. Screw holes 7 are provided around the rear end face of the snap-on plate 10. Hollow threaded posts 18 are fixed around the upper rear side of the door 2. The screw 8 rotates and passes through the screw hole 7 and the hollow threaded post 18. This connection method firmly fixes the snap-on plate 10 to the door 2, ensuring the stable installation of components such as the snap-on plate 6 and enabling them to function properly. A circular groove 15 is provided inside the outer side of the hardware shaft 3. Inner grooves 16 are provided on the front and rear sides of the circular groove 15. A frustum 13 slides inside the circular groove 15. A long rod 11 is fixed in the middle of the outer side of the frustum 13. A short column 12 is fixed in the middle of the outer side of the rear end of the long rod 11. The upper and lower sides of the platform 13 are fixed with cylinders 14, which fit snugly inside the inner groove 16. This structure makes the hardware shaft 3 more stable during rotation, providing reliable support and smooth rotation conditions for the door 2. It ensures that the door 2 will not be unlocked or opened due to external vibration. The door lock switch device unlocks and locks the door 2 through the cooperation of the button 6 and the spring 5, and uses the hardware shaft 3 to realize the rotation of the door 2. The connection and cooperation between the components ensure the stable operation and normal working of the device, and provides convenient opening and use. The aforementioned short column 12 moves in the groove opened at the same level as the external connection structure of the hardware shaft 3. The moving parts of the switch device button 6 of this door lock are made of PA6-RG301 material, which has strong wear resistance. Moreover, its door 2 design is very thoughtful. When closing the door 2, only a light press is needed.The snap button 6 automatically closes, providing a good user experience. Furthermore, regardless of whether the compartment door 2 is open or closed, the overall appearance remains neat and elegant, giving a very comfortable feeling.
