[0039] like Figures 1 to 3 As shown, in some embodiments of the present invention, a Picatinny rail locking device 100 is provided, comprising a connecting base 110 and a locking assembly 120. The connecting base 110 is provided with a mounting slot 111 for mounting the Picatinny rail. The first edge M of the mounting slot 111 has a first through-hole 1111. The locking assembly 120 includes a locking block 121, a locking rod 122, and a locking handle. Partially or entirely, the locking block 121 can be inserted into the first through-hole 1111. Specifically, in this embodiment, the locking block 121 can partially insert into the first through-hole 1111. The end of the locking block 121 away from the Picatinny rail extends outward and can engage with the first edge M of the connecting base 110. The first end L of the locking rod 122 is connected to the locking block 121, and the second end K of the locking rod 122 extends through the second edge N of the mounting slot 111 and is rotatably connected to the locking handle 123. Place the Picatinny rail into the Picatinny rail mounting slot 111 and rotate the locking handle 123 so that the locking block 121 and the second edge N of the mounting slot 111 clamp the Picatinny rail.

[0040] The installation groove 111 is further provided with a guide groove 112 for installing a locking rod 122 . The locking rod 122 can move along its own guide direction in the guide groove 112 .

[0041] In other embodiments of the present invention, the locking block 121 has a threaded hole extending therethrough, and the first end L of the locking rod 122 has a threaded structure that is tightened into the threaded hole to securely connect the locking rod 122 to the locking block 121. In this embodiment, the operator adjusts the length of the locking rod 122 by adjusting the number of turns of the threaded structure between the locking block 121 and the locking rod 122, and then tightens the locking handle 123 to lock the Picatinny rail.

[0042] In some further embodiments of the present invention, Figure 6 As shown, the locking block 121 has a second through-hole 1211. The locking assembly 120 also includes a connector 124, which is disposed within the second through-hole 1211 and has a third through-hole 1241. The locking rod 122 passes through the second through-hole 1211 of the connector 124 and is fixedly connected to the connector 124. Inserting one end of the connector 124 into the second through-hole 1211 completes the installation of the locking block 121 and the connector 124. Then, inserting the locking rod 122 through the third through-hole 1241 of the connector 124 completes the installation of the connector 124 and the locking rod 122. In some embodiments, the locking rod 122 may be provided with a threaded structure, and the third through hole 1241 may be configured as a threaded hole. The threaded structure on the locking rod 122 is then tightened with the threaded hole on the connector 124 to mount the connector 124 on the locking rod 122. Alternatively, the locking rod 122 may be provided with no threaded structure, and one end of the locking rod 122 may be sleeved into the third through hole 1241 on the connector 124.

[0043] In yet other embodiments of the present invention, the first through-hole 1111 of the locking block 121 is configured as a threaded hole. By configuring the connector 124 as an adjustment nut, the adjustment nut is connected to the locking rod 122. Specifically, the adjustment nut and the locking rod 122 are connected via a threaded structure. The locking assembly 120 also includes a locking screw 125, which is used to secure the adjustment nut to the locking rod 122. Specifically, the locking screw 125 presses against the end surface of the adjustment nut, preventing the adjustment nut from loosening.

[0044] A first groove structure is provided at the connection between the adjusting nut and the locking rod 122. The locking assembly 120 also includes a fastening steel ball 126. The fastening steel ball 126 is arranged in the first groove structure to prevent the adjusting nut from loosening. The fastening steel ball 126 is stuck in the first groove structure so that the adjusting nut will not rotate under external force vibration.

[0045] The locking assembly 120 also includes a first elastic member 127. The ends of the first elastic member 127 respectively abut against the locking block 121 and the surface of the Picatinny rail, enabling the locking block 121 and the second edge N of the mounting slot 111 to clamp the Picatinny rail. One end of the first elastic member 127 is fixedly connected to the locking block 121. The first elastic member 127 is configured to move the locking block 121 in the direction guided by the first through-hole 1111 when the locking screw 125 on the adjustment nut is loosened.

[0046] Wherein, first elastic members 127 are provided at both ends of the locking block 121 .

[0047] Optionally, the first elastic member 127 can be configured as a spring, a disc spring or a leaf spring.

[0048] Although not shown in the figures, it will be understood by those skilled in the art that, in other embodiments of the present invention, a guide shaft is provided on the locking block 121, and the guide shaft is formed by extending one end of the locking block 121 in the direction of the Picatinny rail. The first elastic member 127 is sleeved on the guide shaft, and the two ends of the first elastic member 127 are respectively in contact with the locking block 121 and the connecting seat 110. The first elastic member 127 is configured to always remain in a compressed state so that the locking block 121 and the surface of the fastening steel ball 126, and the fastening steel ball 126 and the surface of the adjusting nut are always in contact. In this embodiment, the first elastic member 127 is configured as a spring.

[0049] Specifically, in this embodiment, the following steps are required to turn (twist) the adjusting nut: First, use a flat-blade screwdriver to loosen the locking screw 125 so that the head of the locking screw 125 no longer presses against the end face of the adjusting nut, thereby releasing the first anti-loosening measure. Next, manually press the locking block 121 to compress the first elastic element 127. Simultaneously, the locking block 121 moves in the direction of compression of the first elastic element 127. Because the fastening steel ball 126 is mounted on the locking block 121, the movement of the locking block 121 causes the fastening steel ball 126 to disengage from the groove in the adjusting nut. The adjusting nut is then rotated to allow it to move freely on the locking rod 122.

[0050] The locking assembly 120 further includes a rotating shaft 128, which passes through the second end K of the locking rod 122 and is connected to the locking handle 123. The locking handle 123 can rotate about the rotating shaft 128. Specifically, the connecting base 110, the second end K of the locking rod 122, and the locking handle 123 are all provided with through holes. The rotating shaft 128 can sequentially pass through the through hole on the connecting base 110, the through hole on the second end K of the locking rod 122, and the through hole on the locking handle 123.

[0051] The locking device 100 further includes a locking assembly 130 . The locking assembly 130 is disposed at the second end K of the mounting slot 111 . The locking assembly 130 is used to lock the locking handle 123 .

[0052] The locking handle 123 has a locking groove 1231. The locking assembly 130 includes a locking cover 131. One end of the locking cover 131 is connected to the connecting base 110, and the other end of the locking cover 131 can be engaged with the locking groove 1231 to lock the locking handle 123. Specifically, the locking cover 131 has a protrusion structure that can be engaged with the locking groove 1231.

[0053] The locking groove 1231 can be configured as an arc-shaped groove, and the protruding structure can be configured as a hook structure or an arc-shaped structure matching the arc-shaped groove.

[0054] In other embodiments of the present invention, one end of the locking cover 131 is hingedly connected to the connecting base 110. In this embodiment, the locking assembly 130 further includes a second elastic member 133, the ends of which respectively abut against the connecting base 110 and the inner side of the locking cover 131. The second elastic member 133 is configured to provide a thrust to the locking cover 131 when the locking groove 1231 on the locking handle 123 is unlocked, causing the locking cover 131 to move away from the connecting base 110.

[0055] like Figure 4 and 5 As shown, in other embodiments of the present invention, the locking assembly includes a fixed shaft 134, which is connected to the locking cover 131, and a fourth guide hole is provided on the connecting seat 110.

[0058] Optionally, the second elastic member 133 may be configured as a spring, a disc spring or a leaf spring.

[0059] In this embodiment, the second elastic member 133 is configured as a spring. The locking cover 131 has an extension portion 136, which is provided with a third guide hole. One end of the second elastic member 133 can at least partially be embedded in the third guide hole, and the other end of the second elastic member 133 abuts against the connecting base 110.

[0060] The extending portion 136 and the fixing shaft 134 are both formed by extending the locking cover 131 outward.

[0061] In other embodiments of the present invention, the connection base 110 is provided with a limiting groove, and the locking assembly 130 further includes a housing connected to the limiting groove. The locking cover 131 can be engaged with the housing. In this embodiment, the ends of the second elastic member 133 respectively abut against the housing and the inner side of the locking cover 131 to exert a force to push the locking cover 131 away from the housing.

[0062] In this embodiment, the locking assembly 130 also includes a fastener 132. The edge of the shell and the edge of the limiting groove are both provided with through holes. The fastener 132 passes through the through holes on the edge of the shell and the edge of the limiting groove to fix the shell and the limiting groove.
