2. The connection lock according to claim 1, characterized in that The first mounting base has a first mating surface, and a first locking hole is provided on the first mating surface at the position corresponding to the buckle, and the first locking hole communicates with the first mounting cavity; The second mounting base has a second mating surface, and a second locking hole is provided on the second mating surface at a position corresponding to the first locking hole. A second mounting cavity is provided on the second mounting base at a position corresponding to the second locking hole. The second locking hole communicates with the second mounting cavity, and the locking groove is provided inside the second mounting cavity. After the first locking member and the second locking member are aligned, the first locking hole corresponds to the second locking hole, the fastener extends out of the first locking hole and connects with the locking groove member, and / or the locking groove member extends out of the second locking hole and connects with the fastener.
3. The connection lock of claim 1, wherein The locking rod includes a main rod and at least one drive rod; Along the axial direction of the drive rod, the drive rod is sequentially provided with a drive end, a driven end, and an eccentric cam segment located between the drive end and the driven end. The drive end is drivenly connected to the main body rod, and the drive end and the driven end are coaxially arranged with the main body rod. The eccentric cam segment is eccentrically arranged relative to the main body rod.
4. The connection lock of claim 3, wherein The main rod is provided with a protruding section that is a non-rotational circle in the circumferential direction, and the driving end of the driving rod is provided with a connecting groove that cooperates with the protruding section. The protruding section extends into the connecting groove to drive the main body rod and the drive rod.
5. The connection lock of claim 3, wherein It also includes a mounting block, which is located inside the first mounting cavity and connected to the first mounting base; The mounting block has a U-shaped structure. The driving end and the driven end of the driving rod are rotatably connected to the two side walls of the U-shaped structure, and the eccentric cam segment is located between the two side walls of the U-shaped structure.
6. The connection lock of claim 3, wherein Along the axial direction of the locking rod, the first mounting cavity includes a main body cavity and a driving cavity that communicate with each other; The main body rod is disposed within the main body cavity, and the drive rod is disposed within the drive cavity.
7. The connection lock according to any one of claims 1 to 6, characterized in that The fastener includes a connecting ring and a fastener head connected to the outer ring wall of the connecting ring; The inner ring wall of the connecting ring is provided with a relief groove that is recessed towards the outer ring wall, and the eccentric cam section is provided with a first protruding rib that cooperates with the relief groove. The connecting ring is sleeved on the eccentric cam section, and the first protruding rib extends into the relief groove. The outer ring wall of the connecting ring is provided with a spring mounting groove, and a torsion spring is sleeved on the eccentric cam section. One end of the torsion spring is set in the spring mounting groove, and the other end of the torsion spring is fixed in position. When the locking rod rotates to the first position, the buckle is driven to rotate by the torsion spring; When the locking rod rotates to the second position, it causes the first protruding rib to move within the clearance groove, so that the first protruding rib abuts against one side wall of the clearance groove.
8. The connection lock of claim 7, wherein The buckle head includes a connecting part and a snap-fit part. One end of the connecting part is connected to the connecting ring, and the other end is connected to the snap-fit part, forming a T-shaped structure with the snap-fit part. The locking groove is provided with a T-shaped groove that matches the shape of the buckle head.
9. The connection lock according to any one of claims 1 to 6, characterized in that It also includes a first limiting member, which is movably connected to the first mounting base and can partially extend into the first mounting cavity; A first limiting plane is provided at the position corresponding to the first limiting member of the locking rod. When the locking rod rotates from the first position to the third position in the opposite direction of the first direction, the first limiting member is connected to the first limiting plane to limit the rotation of the locking rod.
10. The connection lock of claim 9, wherein The first limiting member includes a T-shaped member and a second spring, wherein the T-shaped member has a second limiting plane on its horizontal side; The first mounting base is provided with a second limiting cavity extending radially along the locking rod, and the second limiting cavity communicates with the first mounting cavity; The T-shaped component is movably disposed within the second limiting cavity, and the second spring is disposed within the second limiting cavity and sleeved on the vertical side of the T-shaped component; When the locking rod rotates to the third position, the second limiting plane abuts against the first limiting plane.
11. The connection lock according to any one of claims 1 to 6, characterized in that It also includes a second limiting member, which is located inside the first mounting cavity and is movably connected to the first mounting base; The locking rod is provided with a second protruding rib at the position corresponding to the second limiting member, and the second mounting base is provided with an ejector at the position corresponding to the second limiting member; When the second limiting member is in the fourth position, the second limiting member is located on the rotation path of the second protruding rib to limit the amplitude of the locking rod rotation; When the ejector is connected to the second limiting member and the second limiting member is partially moved to the fifth position, the second limiting member avoids the movement path of the second protruding rib, so that the locking rod can rotate.
12. The connection lock of claim 11, wherein, The second limiting member includes a locking block, a limiting connector and a third spring. The locking block has a limiting groove, and the bottom of the limiting groove is provided with a connecting hole.
