Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a mounting structure of a swing arm of a barrier gate, a base plate 1 comprising a plate body 1.1, a connecting sleeve 1.2 fixedly sleeved on the plate body 1.1 at the rear end, and a connecting sleeve 2 1.3 fixed vertically to the front wall of the plate body 1.1 at the rear end, an arc-shaped slide 1.4 fixed to the front wall of the plate body 1.1, and the axis of the connecting sleeve 2 1.3 is located at the center of the circle corresponding to the arc-shaped slide 1.4, and the four corners of the plate body 1.1 are fixed in the barrier gate case by screws. Among them, elastic members 1.5 are respectively provided at the two ends of the inner cavity of the arc-shaped slide 1.4, and the elastic members 1.5 can be selected from springs and the like.

[0024] The driving gear shaft 2 comprises a driving gear 2.1 and a sleeve 2.2 whose front end is fixedly sleeved in the center of the driving gear 2.1. The sleeve 2.2 is rotatably sleeved in the connecting sleeve 1.2. The rear end of the sleeve 2.2 penetrates the plate body 1.1 and is fixedly sleeved with the power output shaft of the driving device.

[0025] The driven gear shaft 3 includes a connecting shaft 3.2 whose rear end is rotatably mounted in the connecting sleeve 2 1.3 and a driven gear 3.1 fixedly mounted on the front end of the connecting shaft 3.2 and meshing with the driving gear 2.1. A plurality of threaded holes 3.1.1 are evenly arranged on the front wall of the driven gear 3.1 near the outer edge along the circumferential direction.

[0026] One end of the swing arm 4 is provided with a through hole 4.1 corresponding to the threaded hole 3.1.1, and a fixing bolt 5 is sleeved in the through hole 4.1, and the rear end of the fixing bolt 5 is threadedly sleeved and matched with the threaded hole 3.1.1. The swing arm 4 is sleeved with a rotating shaft 4.2 at the position corresponding to the arc-shaped slide groove 1.4, and the rear end of the rotating shaft 4.2 is rotatably sleeved with a rotating wheel 4.3, and the rotating wheel 4.3 is slidably clamped in the arc-shaped slide groove 1.4.
