The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figures 1 to 5 This utility model discloses a robotic arm joint connection and suspension motion structure, which includes a lower swing arm 1. A groove 2 is provided at the top of the lower swing arm 1, and an upper swing arm 3 is fitted inside the groove 2. Rotating shafts 6 are bolted to the left and right sides of the upper swing arm 3 near the bottom. A first bearing is fitted onto the outer sleeve of the rotating shaft 6 and is mounted on the inner wall of the groove 2. A housing 4 is located near the top of the right side wall of the lower swing arm 1, and the left side of the housing 4 is open. A box 5 is connected through the right side of the housing 4. A mounting groove 9 is provided on the right side of the rotating shaft 6 located on the right side, and an electric push rod 7 is bolted to the inner wall of the left side of the mounting groove 9. The right end of the electric push rod 7 extends into the housing 4 and is bolted to a plug rod 10. A plug hole 11 is bolted to the plug rod 10. An electric telescopic rod 8 is bolted to the bottom of the inner cavity of the housing 4 near the right side.

[0023] Near the top of the left outer wall of the box 5, a through hole 12 matching the plug-in rod 10 is provided. A movable column 18 is slidably connected to the top of the inner cavity of the box 5. A first slider is bolted to the right side of the movable column 18, and a first sliding groove matching the first slider is provided on the top of the inner cavity of the box 5. An upper spring 19 is connected between the right side of the movable column 18 and the left inner wall of the box 5. A Z-shaped plate 17 is attached to the left side of the movable column 18. A lower spring 16 is bolted to the right side of the Z-shaped plate 17, and the right end of the lower spring 16 is bolted to the right inner wall of the box 5. The Z-shaped plate 17 is connected to the second... The bearing is movably connected to the front and rear inner walls of the housing 5. The insertion hole 11 matches the Z-shaped plate 17. A pressing block 15 is slidably connected to the bottom of the inner cavity of the housing 5 near the left side. A sliding plate 14 is bolted to the bottom of the pressing block 15 near the left side. A second slider is bolted to the bottom of the sliding plate 14.

This structure allows for effective and timely suspension, thus enabling effective stopping and improving its usage and work efficiency.

[0024] Working principle: In use, the electric push rod 7 first extends to the right, causing the plug-in rod 10 to pass through the through hole 12 and enter the box 5. This causes the plug-in rod 10 to squeeze the Z-shaped plate 17 to swing and squeeze the lower spring 16. Then, the plug-in rod 10 drives the moving column 18 to move to the right, squeezing the upper spring 19. This allows the Z-shaped plate 17 to enter the plug-in hole 11, enabling it to hover effectively and timely, thus stopping effectively and improving its usage and working efficiency. Meanwhile, the push rod of the electric cylinder 13 extends to the right, causing the squeezing block 15 to squeeze the left side of the Z-shaped plate 17 near the bottom, causing the Z-shaped plate 17 to swing and disengage from the plug-in hole 11. At this time, the retraction of the electric push rod 7 causes the plug-in rod 10 to move to the left and pass through the through hole 12 to extend outside the box 5, allowing it to be used normally.
