[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, a quick-release and quick-adjust Picatinny adapter includes a fixing base 1, a locking block 2, a locking wrench 6, and a locking rod 3. The locking rod 3 passes through the fixing base 1 and the locking block 2 at the same time. The locking wrench 6 includes an eccentric wheel 6b and a wrench body 6a. The eccentric wheel 6b is rotatably connected to one end of the locking rod 3 through a connecting shaft 7, and the eccentric wheel 6b contacts one side of the locking block 2. A first spring 5 is provided between the locking block 2 and the fixing base 1; and a locking force adjustment mechanism is provided between the other end of the locking rod 3 and the fixing base 1.

[0024] In the present invention, the locking or loosening between the fixing base 1 and the Picatinny rail is achieved by rotating the locking wrench 6; the eccentric wheel 6b is eccentrically connected to one end of the locking rod 3, and the locking wrench 6 will drive the eccentric wheel 6b to rotate when it is rotated; when the locking wrench 6 is rotated in the direction of the fixing base 1, the eccentric wheel 6b rotates and pushes the locking block 2 to move in the direction of the fixing base 1, and the Picatinny rail is located between the fixing base 1 and the locking block 2. The Picatinny rail is clamped by the movement of the locking block 2, thereby achieving the locking between the adapter and the rail (such as Figure 3 On the contrary, when the locking wrench 6 rotates in the direction away from the fixed base 1, the eccentric wheel 6b loosens the locking block 2, and the locking block 2 moves in the direction away from the fixed base 1 under the action of the first spring 5, thereby loosening the connection between the adapter and the guide rail (as shown in FIG. Figure 2(as shown), the adapter can then be removed from the guide rail. The locking force adjustment mechanism allows the locking force between the adapter and the guide rail to be adjusted as needed. The present invention allows for easy installation and removal of the adapter from the guide rail simply by turning the locking wrench 6, eliminating the need for additional tools.

[0025] An eccentric hole is provided on the eccentric wheel 6b, an axial hole 3a is provided at one end of the locking rod 3, and the connecting shaft 7 passes through the axial hole 3a and the eccentric hole at the same time.

[0026] The locking wrench 6 has a locking shaft guide hole, into which a locking shaft 8 is slidably connected. A second spring 9 is interposed between the locking shaft 8 and the locking wrench 6. A locking handle 10 is connected to one end of the locking shaft 8. The locking handle 10 is connected to the locking shaft 8 via a connecting screw 11. One end of the locking rod 3 has a locking hole 3b corresponding to the locking shaft 8. When the locking wrench 6 is locked, the front end of the locking shaft 8 on the locking wrench 6 extends into the locking hole 3b.

[0027] When the locking wrench 6 is in the locking state, the front end of the locking shaft 8 on the locking wrench 6 extends into the locking hole 3b, which can lock the position of the locking wrench 6 and prevent the locking wrench 6 from rotating, thereby preventing the adapter from accidentally loosening from the guide rail during use; when the locking wrench 6 is rotated from the locking state to the unlocking state, the locking handle 10 is first pulled outward to disengage the front end of the locking shaft 8 from the locking hole 3b, and then the locking wrench 6 can be rotated.

[0028] Furthermore, a through hole 1a is provided on the fixed seat 1, and the locking rod 3 passes through the through hole 1a; the locking force adjustment mechanism includes a locking nut 12, a movable gear sleeve 13, and an installation cavity 1b arranged on one side of the through hole 1a, and a first tooth-shaped cavity 1c is provided on the inner side of the installation cavity 1b; the movable gear sleeve 13 is arranged in the installation cavity 1b, and the outer side of the movable gear sleeve 13 is provided with a second external tooth structure 13a that cooperates with the first tooth-shaped cavity 1c, and the movable gear sleeve 13 can slide in the installation cavity 1b to realize the engagement or disengagement of the second external tooth structure 13a with the first tooth-shaped cavity 1c; the inner side of the movable gear sleeve 13 is provided with a second tooth-shaped cavity 13b; the outer side of the locking nut 12 is provided with a first external tooth structure 12a, and the locking nut 12 is arranged in the movable gear sleeve 13, and the first external tooth structure 12a is engaged with the second tooth-shaped cavity 13b; the locking rod 3 is threadedly matched with the locking nut 12 at one end away from the locking wrench 6; an adjusting handwheel 16 is connected to the movable gear sleeve 13.

[0029] Adjustment handwheel 16 is fixedly connected to movable gear sleeve 13. Rotation of adjustment handwheel 16 drives rotation of movable gear sleeve 13. Locking nut 12 is provided with a threaded hole 12b. The end of locking rod 3, away from locking wrench 6, is provided with external threads. These threads connect to threaded hole 12b in locking nut 12. When movable gear sleeve 13 is in its initial state, the second external tooth structure 13a of movable gear sleeve 13 meshes with the first tooth-shaped cavity 1c inside mounting cavity 1b. This interlocking engagement prevents rotation of movable gear sleeve 13 and adjustment handwheel 16. When the movable gear sleeve 13 is in the adjustment state, the adjustment handwheel 16 and the movable gear sleeve 13 are pulled outward to disengage the second external tooth structure 13a on the movable gear sleeve 13 from the first tooth-shaped cavity 1c. At this time, the movable gear sleeve 13 can rotate, while the second tooth-shaped cavity 13b inside the movable gear sleeve 13 and the first external tooth structure 12a outside the locking nut 12 are still in meshing state. By rotating the adjustment handwheel 16, the locking nut 12 is rotated to adjust the locking force. After the adjustment is completed, the adjustment handwheel 16 and the movable gear sleeve 13 are reset to the initial state.

[0030] Among them, the installation cavity 1b is provided with a spring pressure ring 15, and a third spring 14 is provided between the spring pressure ring 15 and the movable gear sleeve 13. After the adjustment hand wheel 16 is adjusted, the third spring 14 can automatically reset the adjustment hand wheel 16 and the movable gear sleeve 13.

[0031] An end away from the locking wrench 6 on the locking rod 3 is provided with an anti-slip screw 17 for limiting the locking nut 12. The anti-slip screw 17 is used to limit the locking nut 12 to prevent the locking nut 12 from being screwed out from the locking rod 3.

[0032] A screw 4 is connected to one side of the fixing seat 1 close to the locking block 2 . The screw 4 passes through the locking block 2 , and the first spring 5 is sleeved on the screw 4 .

[0033] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
