[0004] To address the aforementioned issues, this patent proposes a switch cover structure that is easy to operate and has reliable locking, in order to adapt to frequent switching scenarios and improve the user experience. Utility Model Content

[0005] The main purpose of this utility model is to propose a lifting and rotating switch cover structure, which aims to solve the problems of cumbersome operation and complicated unlocking steps of traditional switch cover structures.

[0006] To address the aforementioned problems, this utility model proposes a lifting and rotating switch cover structure, comprising a lower cover, an upper cover rotatably connected to the rear side of the upper end of the lower cover, and the upper cover being snapped onto the upper end of the lower cover. A switch knob is rotatably connected to the upper end of the upper cover. A limiting ring is connected to the center of the inner wall of the upper end of the upper cover. A connecting shaft is rotatably connected inside the limiting ring, and the connecting shaft passes through the interior of the upper cover and is connected to the center of the lower end of the switch knob. A lower switch chuck is connected to the lower end of the connecting shaft, and the lower switch chuck is located inside the upper end of the lower cover. An upper switch chuck is rotatably connected to the outside of the limiting ring. A locking head is connected to the lower front end of the upper switch chuck. An arc-shaped locking groove is opened on the upper side of the cylindrical inner wall of the lower cover, and the locking head is snapped into the front end of the locking groove.

[0007] Preferably, the upper rear side of the locking slot is connected to an unlocking slide groove, and the unlocking slide groove is opened on the upper left side of the lower cover. The lower front side of the locking slot is connected to a limiting slide groove, and the limiting slide groove is opened on the inner wall of the front end of the lower cover.

[0008] Preferably, a tension spring is provided between the lower switch chuck and the upper switch chuck, and the upper end of the tension spring is located inside the lower end of the upper switch chuck and can be completely retracted into the upper switch chuck. Multiple fitting blocks are connected to the outer side of the upper end of the lower switch chuck.

[0009] Preferably, the upper switch chuck has multiple fitting slots on the outer side of its lower end, and multiple fitting blocks are located directly below the multiple fitting slots, and the front end of the lower switch chuck is connected to a limit card head.

Beneficial effects

[0013] 1. This utility model achieves linkage unlocking by pulling up and rotating the switch knob. The connecting shaft drives the lower switch chuck to move upward and engage with the upper switch chuck. Then, by rotating, the locking head disengages from the locking slot, thus unlocking. This simplifies the opening operation and ensures smooth unlocking. The linkage locking is achieved by rotating the lower switch knob. The engagement between the upper and lower switch chucks drives the locking head into the locking slot. The locking head is locked by the built-in telescopic spring and hemispherical telescopic head, which cooperate with the limiting hole of the locking slot. This enhances the locking stability and prevents accidental opening of the cover.

[0014] 2. The lower switch chuck and the upper switch chuck of this utility model adopt a meshing method of fitting block and fitting slot to ensure effective transmission of rotational force. At the same time, the tension spring realizes automatic reset, which improves transmission stability, prevents slippage, and makes the unlocking process more accurate and reliable.

[0015] 3. The arc-shaped connecting structure of the locking slot, limiting slide, and unlocking slide of this utility model ensures precise guidance of the locking head during rotation. The arc-shaped edge of the unlocking slide optimizes the sliding path of the locking head, making opening the cover smoother and preventing jamming. Attached Figure Description

[0026] 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.

[0027] To achieve the above-mentioned utility model objectives, such as Figures 1-7As shown, this utility model provides a lifting and rotating switch cover structure, including a lower cover 1. An upper cover 2 is rotatably connected to the rear side of the upper end of the lower cover 1, and the upper cover 2 is snapped onto the upper end of the lower cover 1. A switch knob 3 is rotatably connected to the upper end of the upper cover 2. A limiting ring 4 is connected to the center of the inner wall of the upper end of the upper cover 2. A connecting shaft 5 is rotatably connected inside the limiting ring 4, and the connecting shaft 5 passes through the interior of the upper cover 2 and is connected to the center of the lower end of the switch knob 3. A lower switch chuck 6 is connected to the lower end of the connecting shaft 5, and the lower switch chuck 6 is located inside the upper end of the lower cover 1. An upper switch chuck 7 is rotatably connected to the outside of the limiting ring 4. A locking head 8 is connected to the lower side of the front end of the upper switch chuck 7. An arc-shaped locking groove 9 is opened on the upper side of the cylindrical inner wall of the lower cover 1, and the locking head 8 is snapped into the front end of the locking groove 9. An unlocking slide groove 10 is connected to the rear side of the upper end of the locking groove 9, and the unlocking slide groove 10 is opened on the left side of the upper end of the lower cover 1. On the side, the upper end of the lower cover 1 of the switch cover structure can be closed and opened by rotating the upper cover 2. The lower cover 1 and the upper cover 2 can be locked by the engagement between the locking head 8 and the locking groove 9. When the switch cover structure is opened, pull the switch knob 3 upward. The switch knob 3 drives the lower switch chuck 6 to move upward through the connecting shaft 5 and fits against the upper switch chuck 7. Then rotate the switch knob 3. The switch knob 3 drives the upper switch chuck 7 to rotate through the lower switch chuck 6. The upper switch chuck 7 drives the locking head 8 to rotate from the upper end of the limiting slide groove 11 to the lower end of the unlocking slide groove 10 inside the locking groove 9. This allows the locking head 8 to slide upward from inside the unlocking slide groove 10, releasing the lock between the locking head 8 and the locking groove 9. At this time, rotate the upper cover 2 to let the locking head 8 slide out from inside the unlocking slide groove 10 and out of the locking groove 9, thereby opening the switch cover structure.

[0028] Preferably, the lower front end of the locking slot 9 is connected to a limiting slide groove 11, and the limiting slide groove 11 is formed on the inner wall of the front end of the lower cover 1. A tension spring 12 is provided between the lower switch chuck 6 and the upper switch chuck 7, and the upper end of the tension spring 12 is located inside the lower end of the upper switch chuck 7 and can be completely retracted into the upper switch chuck 7. Multiple fitting blocks 13 are connected to the outer side of the upper end of the lower switch chuck 6, and multiple fitting slots 14 are formed on the outer side of the lower end of the upper switch chuck 7, with the multiple fitting blocks 13 located directly below the multiple fitting slots 14. A limiting head 15 is connected to the front end of the lower switch chuck 6, and the limiting head 15 is engaged inside the limiting slide groove 11 and located directly below the locking head 8. A limiting bracket 16 is connected to the left side of the inner wall of the upper end of the upper cover 2, and the tension spring 12 is located in the locking slot 9. On the rear exterior, during the opening of the switch cover mechanism, the switch knob 3 drives the lower switch chuck 6 to engage with the upper switch chuck 7. Simultaneously, multiple engaging blocks 13 engage with multiple engaging slots 14, limiting the movement between the lower switch chuck 6 and the upper switch chuck 7. The limiting head 15 engages with the locking head 8, allowing the limiting head 15 to enter the locking slot 9. The tension spring 12 is completely compressed into the lower end of the upper switch chuck 7, preventing the engagement between the multiple engaging blocks 13 and the multiple engaging slots 14. At this time, rotating the switch knob 3 causes the upper switch chuck 7 to rotate together through the multiple engaging blocks 13 and multiple engaging slots 14 between the lower switch chuck 6 and the upper switch chuck 7, and rotates the limiting head 15 into the locking slot 9.

[0029] When the locking head 8 and the limiting head 15 rotate to the lower end of the unlocking slide 10, they are precisely engaged inside the limiting bracket 16, ensuring that the locking head 8 and the limiting head 15 can smoothly enter the unlocking slide 10 when the switch cover structure is closed. At this time, when the switch knob 3 is released, the lower switch chuck 6, under the action of the tension spring 12, causes the limiting head 15 to fit tightly against the limiting bracket 16, limiting the position between the lower switch chuck 6 and the upper switch chuck 7 and the limiting bracket 16. When the upper cover 2 is rotated, since the upper edge of the inner wall at the rear end of the unlocking slide 10 is arc-shaped, the locking head 8 and the limiting head 15 can smoothly rotate out from inside the unlocking slide 10, allowing the switch cover structure to open smoothly.

[0030] Preferably, the upper end of the locking head 8 is provided with a telescopic sliding hole 17, and a telescopic head 18 is slidably connected inside the upper end of the telescopic sliding hole 17. The upper end of the telescopic head 18 is hemispherical, and a telescopic spring 19 is provided inside the lower end of the telescopic head 18. The telescopic head 18 is elastically connected to the inside of the telescopic sliding hole 17 through the telescopic spring 19. The front side of the upper inner wall of the locking groove 9 is provided with a hemispherical limiting hole 20, and the telescopic head 18 is engaged inside the limiting hole 20. During the process of closing the switch cover structure, the upper cover 2 is rotated and engaged on the upper end of the lower cover 1. At this time, the locking head 8 and the limiting head 15 slide in again to unlock under the action of the upper cover 2. Inside the slide groove 10, the switch knob 3 is turned to unlock the slide groove 10 and slide into the locking slot 9. The locking head 8 and the limiting head 15 are rotated out from inside the limiting bracket 16 and slide inside the locking slot 9. When the locking head 8 and the limiting head 15 are rotated to the upper end of the limiting slide groove 11, the locking head 8 engages with the locking slot 9 again and locks the positions of the lower cover 1 and the upper cover 2. At the same time, the lower switch chuck 6 slides down under the action of the tension spring 12 and drives the limiting head 15 to engage inside the limiting slide groove 11, limiting the lower switch chuck 6 so that the switch knob 3 and the lower switch chuck 6 can only slide up and down and cannot rotate.

[0031] Furthermore, during the sliding process of the locking head 8 inside the locking groove 9, since the upper end of the telescopic head 18 protrudes from the upper end of the locking head 8 and is elastically connected to the inside of the telescopic sliding hole 17, when the locking head 8 rotates towards the limiting sliding groove 11, the telescopic head 18 is completely retracted into the telescopic sliding hole 17 under the pressure of the edge at the intersection of the locking groove 9 and the unlocking sliding groove 10, allowing the locking head 8 to drive the telescopic head 18 to rotate together towards the limiting sliding groove 11. When the locking head 8 rotates to the upper end of the limiting sliding groove 11, the telescopic head 18 is engaged in the limiting hole 20 opened on the upper inner wall of the locking groove 9 under the action of the telescopic spring 19, thereby limiting the position between the locking head 8 and the locking groove 9, and thus locking the position between the lower cover 1 and the upper cover 2.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
