The first locking block 31 and the second locking block 32 are both annular, and the side walls are all inclined.

The inner rings of the first inserting ring 11, the second inserting ring 12, the first locking block 31, the second locking block 32 and the inserting column 2 are provided with locking bolts 33 in a penetrating way. Referring to fig. 3, a hexagonal fixing groove 111 is formed at one end of the first insert ring 11 close to the locking bolt 33, and a head of the locking bolt 33 is inserted into the fixing groove 111, so that the locking bolt 33 is fixed and does not rotate in the through hole. A strip-shaped groove 112 is formed in one end of the first plug-in ring 11 away from the locking bolt 33, and the strip-shaped groove 112 is formed along the diameter of the first plug-in block. The one end an organic whole that first locking piece 31 is close to first grafting ring 11 is provided with joint lug 311, and joint lug 311 and bar groove 112 shape adaptation are pegged graft, make first locking piece 31 can the joint on first connecting ring. The second inserting ring 12 is provided with a waist-round hole 121, and the shape of one end of the second locking block 32 close to the second inserting ring 12 is matched with the shape of the waist-round hole 121. So that the second locking piece 32 is inserted into the waist hole 121 and cannot rotate on the first insert ring 11.

Referring to fig. 2 and 3, a limiting ring 21 is integrally arranged at one end of the plug-in post 2 close to the connecting plug-in, and the axis of the limiting ring 21 is perpendicular to that of the plug-in post 2. The ends of the two ends of the limiting ring 21 are both recessed to form a limiting groove 211, and the first locking block 31 and the second locking block 32 are abutted in the limiting groove 211. One ends of the first locking block 31 and the second locking block 32 close to the limiting ring 21 are abutted against the limiting ring 21. The one end that first locking piece 31 is close to spacing ring 21 all is equipped with chamfer 312, and chamfer 312 has increased the area of contact with spacing ring 21, makes the frictional force between first locking piece 31 and the spacing ring 21 can distribute evenly to can make the butt more fasten. When the angle between the inserting column 2 and the connecting bracket 1 needs to be adjusted, the chamfer 312 can also make the limiting ring 21 rotate between the first locking block 31 and the second locking block 32 more smoothly.

One end, far away from the spacing ring 21, of the second locking block 32 is provided with a gasket 34, the gasket 34 is arranged on the locking bolt 33 in a penetrating mode, one end, far away from the second locking block 32, of the gasket 34 is provided with a locking nut 35, the locking nut 35 is connected to the locking bolt 33 in a threaded mode, the locking nut 35 is screwed up, and the whole structure can be connected and fastened. The washer 34 serves as a tightening means to tighten the connection between the lock nut 35 and the bolt. The side wall of the locking nut 35 is welded with a rotating handle 351, so that the locking nut 35 can be rotated more conveniently.

Referring to fig. 4, a circular placing groove 321 is formed at one end of the second locking block 32 close to the limiting ring 21, and the diameter of the placing groove 321 is larger than the inner diameter of the limiting ring 21. The placing groove 321 is provided with a spring 36 therein, and the spring 36 is disposed on the locking bolt 33, so that the spring 36 is pressed against the side walls of the second locking block 32 and the limiting ring 21. When the angle between linking bridge 1 and the grafting post 2 needs to be adjusted, rotatory lock nut 35, spring 36 is by the compression resume original length gradually, supports second latch segment 32 and moves towards the direction of keeping away from spacing ring 21, can make the friction surface break away from, does not need artificially to go again to take out second latch segment 32 in with spacing ring 21 to make the use can make things convenient for.

The implementation principle of the laminated damping locking device in the embodiment of the application is as follows: when the locking nut 35 is tightened, the friction force between the first locking block 31, the second locking block 32 and the limiting ring 21 causes the first locking block 31 and the second locking block 32 to abut against the limiting ring 21 and abut against the limiting ring 21. When the lock nut 35 is loosened, the spring 36 can be separated from the limit ring 21 by abutting against the second locking block 32, so that the position of the second locking block 32 moved by hands can be saved, and the use is more convenient.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
