DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The outer wall of the fixed block 10 is fixedly connected to the baffle 12 through a connecting mechanism, and the connecting mechanism includes two connecting rods 11 fixedly installed on the outer wall of the fixed block 10, and the ends of the two connecting rods 11 are fixedly connected to the outer wall of the baffle 12. The outer wall of the movable part 5 is fixedly installed with two first connecting frames 14 through a supporting mechanism, and the supporting mechanism includes a supporting plate 13 fixedly installed on the outer wall of the movable part 5, and the first connecting frame 14 is fixedly installed on the outer wall of the supporting plate 13, and a movable plate 15 is rotatably installed inside the two first connecting frames 14.

[0025] The outer walls of the two oil storage sleeves 6 are fixedly installed with connecting channels 16 communicating with the interior, the outer walls of the two connecting channels 16 are fixedly installed with extrusion sleeves 17, the interiors of the two extrusion sleeves 17 are sealed and slidably installed with piston plates 18, the outer walls of the two piston plates 18 are fixedly installed with second connecting frames 19, the ends of the two movable plates 15 are rotatably connected to the interior of the relative second connecting frames 19, the outer walls of the two extrusion sleeves 17 are opened with inlet openings communicating with the interior, and the two air intake openings are fixedly installed with air intake check valves 20.

[0026] When the utility model is used, the connecting plate 9 can be fixedly installed on the outer wall of the fixing member 3 by means of screw accessories, thereby realizing the fixed installation of the baffle 12. During the use of the hinge, the baffle 12 can protect the outer wall of the hinge, thereby preventing dust from entering and adhering to the outer wall of the connecting pipe 1, preventing the connecting pipe 1 from being stuck between the first connecting sleeve 2 and the second connecting sleeve 4, and avoiding affecting the rotation.
