[0028] Such as Figures 1 - 5As shown in the figure, an embodiment of the present utility model provides a self-locking disassembly damper mechanism. The damper is stuck in the installation holes at the box body and the box cover of the automotive armrest box, and the box body and the box cover are rotationally connected through the damper. It includes a bottom plate 1, a positioning seat 2 and a square bar 3 are respectively fixed on the bottom plate 1, a guiding component 4 is arranged on the square bar 3, a sliding seat 6 is arranged on the guiding component 4, and the guiding component 4 is used for guiding when the sliding seat 6 moves. A driving component 5 is arranged on the side of the sliding seat 6. A square block 7 is fixed on one side of the sliding seat 6 close to the positioning seat 2. A sleeve 10 is fixed on the side of the square block 7. A notch is opened at the end of the sleeve 10. Two movable blocks 9 are rotatably connected in the notch. A rotating shaft is fixed in the notch. The movable blocks 9 are movably sleeved on the rotating shaft. When the movable blocks 9 rotate, they rotate around the rotating shaft. A clamping block 8 is fixed on the side of the movable blocks 9. A second curved surface 91 is arranged on the movable blocks 9. The inner wall of the sleeve 10 is slidably connected with the circumferential surface of the ejector rod 11. One end of the ejector rod 11 away from the movable blocks 9 sequentially movably penetrates through the square block 7 and the sliding seat 6 and is fixed with a disc 12.

[0029] As Figure 4 shown, in this embodiment, the guiding component 4 includes a guide rail 41 fixed on the square bar 3 and a guide block 42 fixed on the bottom of the sliding seat 6. The guide block 42 is slidably connected to the guide rail 41. During the movement of the sliding seat 6, the guide block 42 is driven to move along the guide rail 41. The guide rail 41 guides the sliding seat 6 through the guide block 42, making the movement of the sliding seat 6 smoother and more stable.

[0030] As Figure 4 shown, in this embodiment, the guide rail 41 is in the shape of an isosceles trapezoid, and the shape of the inner wall of the guide block 42 is adapted to the shape of the guide rail 41, preventing the guide block 42 from separating from the guide rail 41 in the vertical direction and improving the guiding ability of the guide block 42 and the sliding seat 6 through the shape of the isosceles trapezoid.

[0031] As Figure 2 shown, in this embodiment, the driving component 5 includes a columnar block 52 fixed on the side of the sliding seat 6 and a lever 51 rotatably connected to the side of the square bar 3. A long slot 53 is opened on the circumferential surface of the lever 51. The inner wall of the long slot 53 is slidably connected to the circumferential surface of the columnar block 52. The lever 51 is rotatably connected to the square bar 3 through a round shaft. By rotating the lever 51, the right side of the inner wall of the long slot 53 is driven to squeeze the columnar block 52, so that the columnar block 52 drives the sliding seat 6 to move leftward, and the sleeve 10 can be inserted into the damper.

[0032] As Figure 3 shown, in this embodiment, a flat surface 92 is arranged on the movable block 9. When the two movable blocks 9 rotate, the two flat surfaces 92 on the two movable blocks 9 are mutually attached, preventing the movable blocks 9 from continuing to rotate and realizing the self-locking of the movable blocks 9.

[0033] As Figure 1As shown, in this embodiment, a first curved surface 81 is provided on the side of the clamping block 8 away from the movable block 9. By means of the first curved surface 81, the contact area between the clamping block 8 and the inner wall of the damper is increased, so that the clamping block 8 fits more closely and reliably with the inner wall of the damper.

[0034] As Figure 3 shown, in this embodiment, an anti-slip groove is provided on the side of the disk 12 away from the ejector rod 11 to prevent slipping when pressing the disk 12.

[0035] As Figure 3 shown, in this embodiment, a guide sleeve 13 is fixed to the inner wall of the notch. The inner wall of the guide sleeve 13 is slidably connected to the circumferential surface of the ejector rod 11. The guide sleeve 13 provides guidance for the movement of the ejector rod 11, making the movement of the ejector rod 11 smoother and more stable.

[0036] Working principle: Place the box body and the box cover at the positioning seat 2, and the positioning seat 2 positions them. After positioning, rotate the lever 51, so that the lever 51 drives the right side of the inner wall of the long slot 53 to squeeze the columnar block 52, so that the columnar block 52 drives the sliding seat 6 and the guide block 42 to move leftward along the guide rail 41. The sliding seat 6 drives the sleeve 10 to insert into the hole in the middle of the damper through the square block 7, and the second curved surface 91 on the movable block 9 at the end of the sleeve 10 fits with the side surface of the inner wall of the mounting hole. Continue to push the sliding seat 6 so that the side surface of the inner wall of the mounting hole squeezes the second curved surface 91 on the movable block 9, so that the movable block 9 rotates around the rotating shaft, so that the movable block 9 drives the first curved surface 81 on the clamping block 8 to closely fit with the inner wall of the damper. At the same time, the two flat surfaces 92 on the two movable blocks 9 fit with each other to prevent the movable block 9 from continuing to rotate, realizing the self-locking of the movable block 9;

[0037] After the clamping block 8 is closely attached to the inner wall of the damper, the lever 51 can be rotated in the reverse direction, so that the lever 51 drives the left side of the inner wall of the long slot 53 to squeeze the columnar block 52, so that the columnar block 52 drives the sliding seat 6 to move rightward, so that the sleeve 10, the movable block 9 and the clamping block 8 pull out the damper from the mounting hole. After pulling out, press the disk 12, so that the ejector rod 11 squeezes the movable block 9, and the movable block 9 drives the clamping block 8 to rotate in the reverse direction, so that the clamping block 8 is separated from the inner wall of the damper. After separation, the damper can be removed from the sleeve 10.

[0038] The present utility model covers any substitutions, modifications, equivalent methods and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without the description of these details.

[0039] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
