[0038] Working principle:

[0039] First, according to the actual use space, determine the total width of the door body, and then determine the width of the revolving door 4 according to the total width of the door body. According to the number of revolving doors 4, prepare the corresponding number of bolts 7, so as to facilitate the opening and closing of the door body in a narrow space. Insert expansion screws, etc. into the fixing holes 101, and then fix the base 1 on the ship. Insert the mounting rod 2 into the mounting hole 106. When inserting the mounting rod 2, the fixing block 207 needs to be aligned with the inclined slot 104. Under the action of the inclined slot 104, the fixing block 207 moves in the fixing slot 205. While the fixing block 205 moves inward, it drives the spring 206 to contract until the bottom end of the mounting rod 2 touches the ground of the mounting hole 106. At this time, the fixing block 207 enters the unlocking slot 105 from the inclined slot 104. At this time, under the action of the spring 206, the fixing block 207 enters the unlocking slot 105. When the fixing block 207 enters the unlocking slot 105, the fixing block 207 pushes the unlocking rod 3 to move outward until the unlocking rod 3 completely moves out of the base 1. Then insert the safety rod 302 into the safety hole 301 to complete the installation of the mounting rod 2 and the base 1;

[0040] Then install the door body. Insert the rotating block 403 of the previous revolving door 4 into the rotating seat 402 of the next revolving door 4 in sequence, then insert the bolt 7 into a plurality of first rotating holes 405 and second rotating holes 406, and finally tighten the screw 702 into the threaded hole 701 to prevent the bolt 7 from moving out of the first rotating hole 405 and the second rotating hole 406 to complete the installation of the door body;

[0041] When the installation of the two door bodies is completed, insert the rotating block 403 at the outermost edge of one door body into the rotating seat 402 at the outermost edge of the other door body, and then enter the combined two door bodies from above the mounting rod 2 until the lower surface of the lowermost rotating seat 402 touches the upper surface of the support plate 202. The support plate 202 supports the two door bodies. Finally, screw the fixing sleeve 5 onto the surface of the threaded rod 203 to complete the fixation of the door body and the mounting rod 2;

[0042] In a narrow space, the revolving door 4 can be rotated first on the bolt 7. After rotation, the rotation diameter of the door body decreases, which facilitates the subsequent rotation of the door body. At this time, the rotation diameter of the door body is half or less of that of the double-leaf swing gate, which is convenient for rotation on a narrow ship.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
