Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1-4, the buffering safety device comprises a base 1, wherein the base 1 is arranged on a frame of an X-ray device, a first installation seat 2 is arranged on the base 1, a first installation part 4 is arranged on the first installation seat 2 through a fastening bolt 3, one end of a damper 5 is connected with the first installation part 4, the other end of the damper 5 is connected with a second installation seat 7 through a first connection part 6, a movable pulley 8 is rotatably arranged on the second installation seat 7, a pulley block matched with the movable pulley 8 is arranged above the movable pulley 8, the pulley block comprises a rotating shaft 9, two ends of the rotating shaft 9 are arranged on the frame of the X-ray device through a second installation part 10, a fixed pulley 11 is rotatably arranged on the rotating shaft 9, a steel wire rope 12 is sleeved on the movable pulley 8 and the fixed pulley 11, one end of the steel wire rope 12 is fixed on the frame, and the other end of the steel wire rope 12 is connected with a counterweight 14 through a second connection part 13.

The steel wire rope 12 and the pulley in the utility model can be replaced by chains and chain wheels according to practical situations.

In the utility model, the damper 5 adopts the existing linear damper 5, and because the stroke of the existing linear damper 5 is shorter, the movable pulley 8 is adopted to increase the action stroke range of the damper 5, and for the structure adopting chain and chain wheel transmission, the rotary damper 5 can be added on the chain wheel to replace the linear damper 5.

The two sides of the damper 5 are provided with reset tension springs 15, one ends of the reset tension springs 15 are fixed on the first mounting seat 2, and the other ends of the reset tension springs 15 are fixed on the two sides of the damper 5 through third mounting pieces 16.
