DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] As shown in the accompanying drawings of the embodiments of the utility model, Figure 1 to the accompanying drawings of the embodiments of the utility model, Figure 4 As shown:

[0022] The electric sliding door swing arm connecting rod structure comprises a mounting frame 1, support frames 2 are fixedly installed on both sides of the mounting frame 1, connecting frames 3 are fixedly installed at the bottoms of the support frames 2 through bolts, vertical columns 4 are rotationally connected to the lower surfaces of the connecting frames 3, upper swing arms 7 are fixedly sleeved on the outer walls of the upper portions of the vertical columns 4, second pin rods 8 are fixedly connected to the other ends of the upper swing arms 7, swing arm connecting rod structures 6 are movably sleeved on the outer walls of the second pin rods 8, and first pin rods 5 are movably sleeved at the other ends of the swing arm connecting rod structures 6.

[0023] The swing arm connecting rod structure 6 comprises an adjusting screw 601 and joint bearings 602. The outer walls of both ends of the adjusting screw 601 are provided with external threads. The joint bearings 602 are two. The ends of the two joint bearings 602 are provided with grooves. The grooves in the joint bearings 602 are provided with internal threads. The adjusting screw 601 is in threaded connection with the joint bearings 602. The connecting portions of the joint bearings 602 are sleeved with elastic washers 607. The outer walls of both ends of the adjusting screw 601 are in threaded connection with fixed nuts 604. The fixed nuts 604 are in contact with the outer walls of the joint bearings 602. The middle portion of the outer wall of the adjusting screw 601 is fixedly sleeved with an adjusting nut 603. The two fixed nuts 604 are located at the two sides of the adjusting nut 603.
