Description

Technical Field

[0001] The utility model relates to the field of power-assisted manipulators, in particular to a linkage device capable of rotating 90 degrees. Background Art

[0002] The traditional structure generally uses a cylinder on the crossbar to realize the rotation of the fixture. If the crossbar needs to be rotated, a rotating cylinder needs to be added between the fixed flange and the crossbar. The traditional structure involves two types of cylinders, which is not only costly, poor in linkage, and more complicated in structure, but also can only carry very small loads due to the limitation of the swing cylinder structure. Utility Model Content

A mounting seat is fixedly connected to the upper end of one side of the cross bar, and the mounting seat is rotatably connected to the bottom of the transition connecting rod. A cylinder and a button box for controlling the cylinder are fixedly connected to the front of the cross bar. A connecting rod is movably arranged on the outer side of the transition connecting rod, and the power end of the cylinder drives the connecting rod to drive the cross bar to rotate 90 degrees.

[0005] Preferably, a fixing seat is fixedly connected to the other side of the cross bar, a second rotating shaft is rotatably connected inside the fixing seat, and a rotating connecting rod is rotatably connected to the outer side of the second rotating shaft.

[0006] Preferably, both ends of the rotating connecting rod are respectively connected to the cylinder power end and the connecting rod.

[0007] Preferably, the rotary connecting rod and the cylinder, the connecting rod, and the connecting rod and the transition connecting rod are all rotatably connected via a rotating pin.

[0008] Preferably, an oil pressure buffer is also provided on the outer side surface of the connecting rod.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model utilizes the extension and retraction of the cylinder to drive the second rotating shaft and the rotating connecting rod to rotate 90 degrees, and then the rotating connecting rod drives the transition connecting rod through the connecting rod to realize the 90 degree rotation of the cross bar. The overall connecting rod structure design is simple and has better overall linkage. Only one cylinder is used for the overall drive, so the cost is lower and it also has a certain load-bearing capacity. The practical effect is obvious and it is worthy of promotion and use in the existing market. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Reference Manual Attached Figure 1-2 A linkage device that rotates 90 degrees includes a cross bar 1 and a first rotating shaft 3. The upper end of the first rotating shaft 3 is fixedly connected to the operating equipment. The bottom of the first rotating shaft 3 is fixedly connected to a transition connecting rod 4. The first rotating shaft 3 and the operating equipment and the transition connecting rod 4 are all detachably fixedly connected through a Ferra disc 301 and fasteners. The upper end of one side of the cross bar 1 is fixedly connected to a mounting seat 2, and the mounting seat 2 is rotatably connected to the bottom of the transition connecting rod 4. The front of the cross bar 1 is fixedly connected to a cylinder 5 and a button box 8 for controlling the cylinder 5. The transition connecting rod 4 is fixedly connected to the upper end of the cross bar 1. A connecting rod 6 is movably provided on the outside of the rod 4, and the power end of the cylinder 5 drives the connecting rod 6 to drive the cross bar 1 to rotate 90°. A fixed seat 101 is fixedly connected to the other side of the cross bar 1. The fixed seat 101 is rotatably connected to the second rotating shaft 102, and the outer side of the second rotating shaft 102 is rotatably connected to a rotating connecting rod 103. The two ends of the rotating connecting rod 103 are respectively connected to the power end of the cylinder 5 and the connecting rod 6. The rotating connecting rod 103 and the cylinder 5, the connecting rod 6, and the connecting rod 6 and the transition connecting rod 4 are all rotatably connected through a rotating pin 601.

[0019] Based on the above structure, when the utility model is in use, the switch start cylinder 5 in the button box 8 extends and retracts, thereby driving the second rotating shaft 102 and the rotating connecting rod 103 to rotate 90°, and then the rotating connecting rod 103 drives the transition connecting rod 4 through the connecting rod 6. Since the upper end of the first rotating shaft 3 is fixedly connected to the operating equipment, the cross bar can be rotated 90° when the connecting rod 6 cooperates with the transition connecting rod 4 for transmission. Based on this, the overall connecting rod structure design is adopted, which is simple and has better overall linkage. In addition, the overall drive is only driven by one cylinder, the cost is lower, and it also has a certain load-bearing capacity, and the practical effect is obvious.
