[0022] like Figures 1 to 3 A thin film material anti-falling safety protection device is shown, comprising a flange base 1, a semicircular coupling tray 2 and a translation ring 3;

[0023] There are two flange bases 1, which are respectively arranged on two supports 4 opposite to each other. The two supports 4 are relatively vertically arranged, and a spacing is left between the two supports 4. Semicircular coupling trays 2 are respectively arranged on the two flange bases 1, and an inflatable shaft 10 is arranged between the two semicircular coupling trays 2; that is, the shaft heads at both ends of the inflatable shaft 10 are respectively arranged on the two semicircular coupling trays 2, and the inflatable shaft 10 is supported by the two semicircular coupling trays 2, and a thin film material is wound around the inflatable shaft 10;

[0024] A translation ring 3 is sleeved on the outer ring of the semicircular coupling tray 2, and the translation ring 3 reciprocates along the semicircular coupling tray 2. A first connecting hole 5 is provided on the translation ring 3, and a second connecting hole 6 is provided on the semicircular coupling tray 2. The first connecting hole 5 and the second connecting hole 6 are connected by a connecting piece 7; the first connecting hole 5 and the second connecting hole 6 are fixed by the connecting piece 7, and then the translation ring 3 and the semicircular coupling tray 2 are fixed;

[0025] The semicircular coupling tray 2 is provided with a limiting member 8 , and the translation ring 3 is provided with a limiting groove 9 , and the limiting member 8 is clamped in the limiting groove 9 to limit the translation ring 3 .

[0026] The use process of the thin film membrane anti-fall safety protection device of the utility model is as follows: first, before the production of the automobile paint protection film is started, the two translation rings 3 are moved along the corresponding semicircular coupling trays 2 toward the flange base 1, and the air shaft 10 is installed on the two semicircular coupling trays 2, and then the two translation rings 3 are reset. Specifically, the two translation rings 3 are moved along the corresponding semicircular coupling trays 2 toward the air shaft 10 until the limiting groove 9 on the translation ring 3 abuts against the limiting piece 8 on the semicircular coupling tray 2, at this time, the first connecting hole 5 and the second connecting hole 6 match and overlap, and the connecting piece 7 is installed in the first connecting hole 5 and the second connecting hole 6 to realize the connection between the translation ring 3 and the semicircular coupling tray 2, and because the air shaft 10 is arranged on two semicircular coupling trays 2, and the translation ring 3 is sleeved on the semicircular coupling tray 2. The translation ring 3 is used to prevent the inflatable shaft 10 from falling, thereby effectively playing a role in preventing the thin film material on the inflatable shaft 10 from falling and protecting it from safety, thereby improving the safety and stability of the winding of the thin film material on the inflatable shaft 10; after the production and winding of the thin film material on the inflatable shaft is completed, when the inflatable shaft needs to be removed from the two semicircular coupling trays, it is only necessary to release the connection relationship between the connecting piece 7 and the first connecting hole 5 and the second connecting hole 6, and then move the translation ring 3 along the semicircular coupling tray 2 toward the flange base 1 until the translation ring 3 is completely separated from the semicircular coupling tray 2. At this time, the inflatable shaft 10 can be directly removed from the semicircular coupling tray 2, and the operation is simple and convenient. The film material anti-falling safety protection device can support the semicircular coupling tray 2 and then the air shaft 10 by translating the ring 3 in the event of human error operation or sudden air failure in the air system, so that the film material will not fall to the ground and injure people, thereby improving the stability and safety of the film material winding.

[0027] As a preferred embodiment, a limiting member 8 is provided on the outer wall of one end of the semicircular coupling tray 2 provided with an inflatable shaft in the present application, and the limiting member 8 is a limiting bolt; a limiting groove 9 is provided on the end of the translation ring 3 close to the inflatable shaft.

[0028] When the translation ring 3 moves along the semicircular coupling tray 2 to a position close to one end of the air shaft, when the limit groove 9 on the translation ring 3 abuts against the limit bolt, it means that the translation ring 3 has moved into place along the semicircular coupling tray 2. The setting of the limit groove 9 and the limit bolt prevents the translation ring 3 from moving beyond the stroke along the semicircular coupling tray 2, thereby ensuring the stability of the movement of the translation ring 3.

[0029] More specifically, the limit groove 9 on the translation ring 3 in the present application is U-shaped, and protrudes from one end close to the inflatable shaft to the bottom end close to the flange base. The U-shaped limit groove is easy to match with the outer contour of the limit bolt, thereby improving the stability of the limit bolt in limiting the limit groove.

[0030] As a preferred embodiment, the first connecting hole 5 in the present application is arranged at one end of the translation ring 3 close to the inflatable shaft, the second connecting hole 6 is arranged at one end of the semicircular coupling tray 2 close to the inflatable shaft, and the connecting member 7 is a screw; that is, after the translation ring 3 moves along the semicircular coupling tray 2 to one end close to the inflatable shaft, the first connecting hole on the right side of the translation ring 3 and the second connecting hole 6 on the semicircular coupling tray 2 match, so that the translation ring 3 completely covers the end of the semicircular coupling tray supporting the inflatable shaft, improves the stability of the translation ring 3 supporting the inflatable shaft, and prevents the inflatable shaft from falling. The screw in the present application is a butterfly screw, which is convenient for the staff to manually connect the translation ring 3 and the semicircular coupling tray 2 together.

[0031] As a preferred embodiment, the flange base 1 in the present application is fixed to the support 4 by bolts, and the semicircular coupling tray 2 and the flange base 1 are fixedly connected, thereby improving the stability and safety of the connection between the semicircular coupling tray 2 and the flange support 1.

[0032] The inner wall of the semicircular coupling tray 2 in the present application is an arc-shaped one that matches the outer walls at both ends of the inflatable shaft, so that the two ends of the inflatable shaft can be placed in the semicircular coupling tray 2 in a matching manner, and the inflatable shaft can be supported by the semicircular coupling tray 2.
