[0021] See also Figure 1 、 Figure 3 and Figure 4 The squeezing mechanism 10 includes a cross bar 15, which is movably connected to the inner cavity of the externally threaded rod 9. A push plate 16 and a handle 17 are fixedly connected on both sides of the cross bar 15. By setting the handle 17, the cross bar 15 and the push plate 16, the oil bag 12 can be squeezed to thereby achieve the oil discharge effect. A first spring 18 is fixedly connected to the left side of the handle 17. The left side of the first spring 18 is fixedly connected to the externally threaded rod 9. By setting the first spring 18, the push plate 16 can be reset after squeezing, which is conducive to the reuse of the device.

[0022] See also Figure 1 、 Figure 2 and Figure 3 The right side of the telescopic oil pipe 14 is connected to a branch pipe, and there are three branch pipes. By setting the telescopic oil pipe 14 and the branch pipe, the hinge of the first connecting plate 6 and the second connecting plate 7 can be lubricated, which is beneficial to reduce wear during movement. The right side threaded sleeve of the branch pipe is provided with a pipe cover 19.

[0023] See also Figure 1 and Figure 3The front and rear sides of the left side of the telescopic oil pipe 14 are fixedly connected with auxiliary rods 20. The right side of the inner cavity of the first connecting block 1 is connected with an auxiliary cylinder 21. The left side of the auxiliary rod 20 passes through the inner cavity of the auxiliary cylinder 21. The surface of the auxiliary rod 20 is provided with an arc-shaped protrusion, and the inner cavity of the auxiliary cylinder 21 is provided with two grooves. The arc-shaped protrusion can be snapped into the groove, thereby fixing the auxiliary rod 20 in different positions, which is beneficial to the left and right movement of the telescopic oil pipe 14. By setting the auxiliary rod 20 and the auxiliary cylinder 21, the position of the branch pipe can be adjusted, so that the telescopic oil pipe 14 and the branch pipe can be placed when idle.

[0024] See also Figure 1 、 Figure 3 and Figure 4 A cavity is opened in the inner cavity of the first connecting block 1, and the oil bag 12 is located in the inner cavity of the cavity. A through hole is opened on the right side of the cavity, so that the push plate 16 can move and contact with the pressure plate 13. Both sides of the right side of the pressure plate 13 are fixedly connected with a second spring 22, and the right side of the second spring 22 is fixedly connected to the inner cavity of the cavity. By setting the second spring 22, the pressure plate 13 can be reset to the right after being pressurized, which is beneficial to the re-lubrication process.

[0025] See also Figure 1 、 Figure 3 and Figure 4 A round hole is opened on the left side of the first threaded cylinder 8. By setting the first threaded cylinder 8 and the second threaded cylinder 11, the front frame and the rear frame can be connected, which facilitates the overall movement of the bracket transporter. The second connecting plate 7 is fixedly connected to the second connecting rod 4. The top of the oil bag 12 is connected to the refueling pipe, and the top of the refueling pipe passes through the first connecting block 1.

[0026] When in use, the first connecting block 1 and the second connecting block 2 are connected to the front frame and the rear frame respectively, and the front and rear frames can be moved and rotated at any angle through the hinge shaft 5, the first connecting plate 6 and the second connecting plate 7, which improves the flexibility of the connection and helps to reduce the bumps of the support transporter during driving. When it is necessary to lubricate the hinge, move the branch pipe to the right to extend the telescopic oil pipe 14, and the auxiliary rod 20 slides in the auxiliary cylinder 21 until the arc-shaped protrusion is stuck in the groove on the right, and then fix the oil outlet end of the branch pipe at the hinge of the first connecting plate 6 and the second connecting plate 7, open the pipe cover 19, and then rotate and move the external threaded rod 9 to the left so that the external threaded rod 9 moves to the left side of the inner cavity of the first threaded cylinder 8, press the handle 17 and push it to the left, the first spring 18 is compressed, and the oil outlet end of the branch pipe is fixed at the hinge of the first connecting plate 6 and the second connecting plate 7. The cross bar 15 makes the push plate 16 contact and squeeze the pressure plate 13, so that the oil bag 12 is pressurized and oil is discharged through the telescopic oil pipe 14. At this time, the second spring 22 is compressed, and the oil lubricates the hinge. After lubrication, the first spring 18 and the second spring 22 are reset, which is beneficial to the subsequent lubrication process. When the front frame and the rear frame need to be connected, the externally threaded rod 9 is rotated to the right and moved so that the right side of the externally threaded rod 9 is inserted into the second threaded barrel 11 and is threadedly connected to the second threaded barrel 11. At this time, the first connecting block 1 and the second connecting block 2 can be relatively fixed, so that the front frame and the rear frame form a whole, which is beneficial to the overall movement of the bracket transporter. When the externally threaded rod 9 hinders the movement of the hinge, the operator can unscrew the externally threaded rod 9 from the first threaded barrel 8 as a whole.

[0027] To sum up: the articulated device for the bracket transporter solves the problem that it usually does not have the advantage of being more convenient for lubrication and the problem that the articulated structure cannot be fixed through the cooperation of the extrusion mechanism 10, the oil bag 12, the pressure plate 13, the telescopic oil pipe 14, the cross bar 15, the push plate 16, the handle 17, the first spring 18, the auxiliary rod 20, the auxiliary cylinder 21, the first connecting block 1, the second connecting block 2, the first connecting rod 3, the second connecting rod 4, the first threaded cylinder 8, the externally threaded rod 9 and the second threaded cylinder 11.
