[0012] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0013] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See also Figures 1 to 4 As shown, a protective door safety sealing structure involved in this embodiment includes a door frame 1 and a door panel 2 hinged on the door frame 1, the door frame 1 is provided with a closed ring-shaped outer retaining ring 3 on one end facing the door panel 2, and the door panel 2 is provided with a closed ring-shaped inner retaining ring 4 on one end facing the door frame 1, the outer retaining ring 3 is arranged outside the inner retaining ring 4, and a sealing channel 5 is provided between the outer retaining ring 3 and the inner retaining ring 4, the outer half of which is opened on the outer retaining ring and the inner half is opened on the inner retaining ring, the sealing channel 5 is filled with a flexible hose 6 also in a closed ring shape, a plurality of spherical protrusions 7 are arranged on the outer tube wall of the flexible hose 6, and a spherical groove 8 matching the spherical protrusions one by one is provided on the channel wall of the sealing channel 5, the spherical protrusion 7 is embedded in the spherical groove 8, and the spherical groove 8 is arranged on the outer retaining ring 3, the flexible hose 6 is provided with an air nozzle 9, and the outer retaining ring 3 is provided with a working opening 10 with the air supply nozzle exposed to the outside.

[0016] Furthermore, the spherical protrusions 7 are arranged at intervals along the extension track of the flexible hose 6; and the interval between two adjacent spherical protrusions 7 is equal.
