Embodiment Construction

[0030] The invention will be described in more detail hereinafter with reference to the accompanying drawings showing embodiments of the invention. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In these drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0031] refer to Figure 1-6 , the present invention provides an arched door opening and closing device, which is suitable for the arched door on the side of the cylindrical cabin body, mainly including a circumferential sliding mechanism 12 and a radial pressing mechanism 11 to realize the circumferential movement of the door. To move out of the door position, press in and out of the door frame circumferentially.

Abstract

The invention provides an arch cabin door opening and closing device which comprises a circumferential sliding mechanism and a radial compressing mechanism. The circumferential sliding mechanism comprises a shifting driver, an arc rail and at least one shifting shaft. The arc rail is arranged on a cabinet body through a circumferential movement track of a cabin door. The shifting shaft is connected with the cabin door. The shifting driver drives the shifting shaft to move along the arc rail. The radial compressing mechanism comprises a compressing driver, a connecting rod and at least one compound screw shaft. One end of the connecting rod is connected with the cabin door. The other end of the connecting rod is connected with the compound screw shaft through a nut. A screw rod is sleeved with the nut. The compressing driver drives the compound screw shaft to rotate, so that the nut moves in the axial direction of the compound screw shaft, the nut drives the cabin door to move in the radial direction through the connecting rod, and the cabin door is compressed into or pulled out of a door frame. The arch cabin door opening and closing device is applicable to the arch cabin door on the side face of the cylindrical cabin body and has the advantages of being small in motion envelope, simple in structure, low in weight, high in reliability and the like.

Description

technical field [0001] The invention relates to the technical field of design of an opening and closing device, in particular to an opening and closing device for an arch hatch. Background technique [0002] Hatch door opening and closing devices are widely used in ships, boats, boats and aircrafts, and they are all occasions that need to provide a closed environment; common hatches are more common with plane or approximate planes, and arched hatches on the sides of cylindrical cabins It is relatively rare; and the existing arched hatches used on the side of the cylindrical cabin have problems such as large motion envelope, heavy weight, and poor reliability. Contents of the invention [0003] In order to solve the above problems, the present invention provides an arched hatch door opening and closing device for moving the hatch door into or out of the door frame on the cabin body, characterized in that the arched hatch door opening and closing device includes a circumfere...
