[0002] According to Chinese Patent No. CN221298918U, an external motor damper structure is disclosed. This external motor damper structure is installed on the support rod of an electric tailgate of an automobile. The structure includes a motor, a damping assembly, and a cover connected to the output end face of the motor. The cover has a through hole in the center for the motor output shaft to pass through, and a circumferential rim around its outer periphery. After the cover is connected to the motor, it forms a mounting cavity. The damping assembly is mounted on the motor output shaft via a bushing and is circumferentially fixed within the mounting cavity. The damping assembly includes a friction ring and an elastic retaining ring, with the inner ring of the elastic retaining ring tightly gripping the friction ring. Compared to existing dampers, this invention has advantages such as simple structure, lightweight, and low cost.

[0003] However, the above-mentioned documents and existing technologies have the following problems: when the damper stops working, it is not convenient to completely wrap the working end of the damper, which may cause the working end of the damper to be subjected to external force, damaging the internal structure, reducing the service life and working effect of the damper, and the existing locking device is complex in structure and has high production cost when adapting to dampers of different sizes.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-5 The system includes a locking box 1, which is the core component. Two sets of locking blocks 2 are provided on one side of the locking box 1 to facilitate engagement with the connecting frame 7. A locking groove 3 is provided in the middle of one side of the locking box 1 to accommodate the locking mechanism. A closing cover 6 is provided on the top of the locking box 1. A rotating groove is provided on the top of the closing cover 6. A rotating rod 4 is rotatably connected inside the rotating groove. A groove is provided in the middle of the rotating rod 4, and the surface of the groove rotates inside the rotating groove. The top and bottom of the rotating rod 4 are rotatably connected to the top and bottom of the rotating groove, ensuring the stability of the rotating rod 4. The top of the rod 4 is equipped with a convenient block 5. One side of each of the two sets of locking blocks 2 is provided with a connecting frame 7. The connecting frame 7 has a connecting groove inside. One side of the connecting frame 7 is threaded with four sets of external screws 8. The four sets of external screws 8 are arranged in a rectangular row. The connecting frame 7 is connected to one end of the damper through the four sets of external screws 8 to ensure a firm connection. Both ends of the locking box 1 are provided with anti-slip grooves. The two sets of anti-slip grooves are provided with anti-slip blocks 9 inside. The two sets of anti-slip blocks 9 are designed to increase the friction between the locking box 1 and the worker's hand, reducing the slippage of the hand during the installation of the locking box 1.

[0026] The bottom of the closed cover 6 has two sets of sliding grooves. A gear 10 is located at the bottom of the rotating rod 4. One end of the gear 10 meshes with rack A 11, and the other end meshes with rack B 12. Sliding blocks 13 are located at the top of both rack A 11 and rack B 12. The tops of the two sets of sliding blocks 13 are evenly distributed within the two sets of sliding grooves, ensuring smooth movement of rack A 11 and rack B 12. Friction exists between rack A 11, rack B 12, and gear 10. Under no external force, rack A 11, rack B 12, and gear 10 will not displace. The bottom of rack A 11 is... A connecting rod 14 is provided at the bottom of the rack 12, and a connecting rod 15 is provided at the bottom of the rack 12. A locking block 16 is provided at one end of both connecting rods 14 and 15. Several friction blocks are provided on the surface of one end of the two sets of locking blocks 16. The friction blocks are provided to increase the friction between the locking block 16 and the moving end of the damper, so that the locking of the moving end of the damper is more secure. Through slots are provided at both ends of the locking groove 3. The surfaces of the connecting rods 14 and 15 are evenly arranged in the two sets of through slots to ensure that the connecting rods 14 and 15 move smoothly in the locking groove 3 and avoid jamming. Specific Implementation Example 2:

[0028] The stepper motor damper locking device, based on the basic structure in Specific Embodiment 1, further discloses the following: its working principle and steps are as follows: The operator first connects one end of the damper with four sets of external screws 8, allowing the moving end of the damper to pass through the interior of the connecting groove. Then, two sets of locking blocks 2 are inserted into one end of the connecting frame 7, connecting the locking box 1 and the connecting frame 7. One end of the damper also enters the interior of the locking groove 3. The convenient block 5 is rotated counterclockwise. The rotation of the convenient block 5 drives the gear 10 to rotate synchronously. The rotation of the gear 10 drives rack A 11 and rack B 12 to move in opposite directions. The two sets of sliding blocks 13 move inside the sliding groove to ensure the normal operation of rack A 11 and rack B 12. A connecting rod 14, B connecting rod 15 and the two sets of locking blocks 16 move with the movement of rack A 11 and rack B 12 until the two sets of locking blocks 16 clamp the moving ends of dampers of different sizes, ensuring the locking and limiting of the moving ends of the dampers.

[0029] In summary:

[0030] 1. The device employs a convenient block 5, a rotating rod 4, a gear 10, rack A 11, rack B 12, connecting rod A 14, connecting rod B 15, and locking block 16. When the moving end of the damper enters the locking groove 3, the operator needs to rotate the convenient block 5 counterclockwise. The rotation of the convenient block 5 drives the gear 10 to rotate synchronously. The rotation of the gear 10 drives rack A 11 and rack B 12 to move in opposite directions. Connecting rod A 14, connecting rod B 15, and the two sets of locking blocks 16 move along with rack A 11 and rack B 12 until the two sets of locking blocks 16 clamp the moving end of the damper. This achieves the locking of the moving ends of dampers of different sizes. The locking box 1 completely encloses the moving end of the damper, preventing rotation when the moving end stops working under external force.

[0031] 2. The design employs a connecting frame 7, a locking block 2, and external screws 8. During use, the connecting frame 7 and one end of the damper can be connected using four sets of external screws 8. The moving end of the damper passes through the interior of the connecting groove. The locking box 1 is connected to the connecting frame 7 via two sets of locking blocks 2. This allows for quick connection and disassembly of the connecting frame 7 and the locking box 1, facilitating its use when carried with the damper.
