Description

Technical Field

[0001] This invention relates to the field of marine curtain technology, specifically to a marine concealed curtain and curtain box. Background Technology

[0002] Ship curtains and curtain boxes are typically surface-mounted, requiring interior decoration to be completed before installation. During operation, ships are affected by various external factors such as wind, waves, and currents, causing the hull to roll and sway. Curtains hanging inside the cabin are likely to sway with these forces, potentially generating sudden force. If crew members or passengers accidentally approach or touch a swaying curtain, they may be cut or scratched by its edges or hooks. In emergencies, such as a sudden increase in ship rolling, the swaying curtains could become obstacles, increasing the risk of falls or collisions. Therefore, we propose a concealed ship curtain and curtain box. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention designs the curtain as consisting of two half-curtains, an upper curtain and a lower curtain. Magnetic female and male components are respectively installed at one end of the upper and lower curtains, which interlock with each other. The magnetic attraction improves the tightness of the curtain when closed. A curtain frame and curtain rail are set to restrict the position of the curtain inside the curtain frame, thus fixing the curtain by eliminating the transmission and suspension method. Two auxiliary rollers set on the curtain frame and the curtain rail limit the range of motion of the curtain, thereby preventing the curtain from swinging with the ship's movement and eliminating the safety hazards caused by the curtain swaying. Furthermore, the overall structure can be embedded inside the side wall of the ship's cabin to improve the overall aesthetics.

[0015] 2. This invention adjusts the state of the transmission component by establishing a control component, which in turn adjusts the distance between the lower and upper curtains using its internal parts, thereby realizing the opening and closing of the entire curtain and ensuring the basic function of the overall device. The control component can lock itself when no one is operating it, thereby improving the stability of the overall device. The entire control component is simple to operate and highly efficient. In addition, a winding component is provided to wind up the excess parts of the upper and lower curtains when the curtains are opened, thereby avoiding interference with the operation of other components and ensuring the rationality of the overall structural design.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-8 This invention provides a technical solution: a marine concealed curtain, comprising an upper curtain 1 and a lower curtain 2. A magnetic female component 3 is fixedly installed on the lower surface of the upper curtain 1, and a magnetic male component 4 is fixedly installed on the upper surface of the lower curtain 2 near the magnetic female component 3. The magnetic male component 4 and the magnetic female component 3 are magnetically connected. The magnetic female component 3 has a slot for engaging with the magnetic male component 4. An auxiliary roller 5 is fixedly installed on the upper curtain 1. There are two auxiliary rollers 5, and the auxiliary roller 5 furthest from the upper curtain 1 is fixedly connected to the lower curtain 2, making the overall structure design simpler, easier to install, and saving manpower.

[0027] The curtain box of the marine concealed curtain of the present invention includes a curtain frame 6, a decorative panel 8 installed on the outer surface of the curtain frame 6, and a curtain guide rail 7 rotatably connected to an auxiliary roller 5. Two curtain guide rails 7 are provided, symmetrically fixedly installed on both sides of the curtain frame 6. The upper curtain 1 and the curtain guide rail 7, as well as the lower curtain 2 and the curtain guide rail 7, are slidably connected. A control assembly 9 is provided on the decorative panel 8, including a turntable 91, an extension rod 92, a friction block 93, a ball joint rod 94, a connecting seat 95, a return torsion spring 96, a connecting shaft 97, a cam 98, an auxiliary spring 99, and an auxiliary ring 910. The turntable 91 is fixedly installed on the end face of the first transmission shaft 101, and the extension rod... 92 is rotatably connected to connecting seat 95 via connecting shaft 97. Friction block 93 is fixedly installed on the end face of ball head rod 94. Ball head rod 94 is slidably set on turntable 91. Connecting seat 95 is fixedly installed on the side of turntable 91. The two ends of return torsion spring 96 are fixedly connected to connecting seat 95 and connecting shaft 97 respectively. Cam 98 is fixedly installed on extension rod 92. The two ends of auxiliary spring 99 are fixedly connected to auxiliary ring 910 and turntable 91 respectively. Auxiliary ring 910 is fixedly installed on ball head rod 94. The decorative plate 8 is provided with annular friction texture for enhancing friction. The friction texture cooperates with friction block 93 to ensure the rationality of the established structure, thereby achieving the purpose of pre-establishing such structure.

[0028] The curtain track 7 is internally equipped with a transmission assembly 10 and a winding assembly 11. The transmission assembly 10 includes a first transmission shaft 101, two sliders 102, two lead screws 103, a second transmission shaft 104, a first gear 105, a second gear 106, a worm gear 107, a pulley set 108, and a worm 109. The first transmission shaft 101 is rotatably mounted on the curtain track 7 and rotatably connected to the decorative panel 8. The two sliders 102 are respectively fixedly installed on the upper curtain 1 and the lower curtain 2, and the sliders 102 are slidably connected to the curtain track 7. The two lead screws 103 are rotatably mounted on the curtain track 7 and are threadedly connected to the two sliders 102 respectively. The second transmission shaft 104 is rotatably mounted inside the curtain track 7. The first gear 105 is fixedly mounted inside the curtain track 7. Mounted on the second drive shaft 104, the second gear 106 is fixedly mounted on the end face of one of the lead screws 103. The second drive shaft 104 is connected to the other lead screw 103 via a pulley set 108. The worm gear 107 is fixedly mounted on the second drive shaft 104 and threadedly connected to the worm 109. The worm 109 is fixedly mounted on the end face of the first drive shaft 101. The first gear 105 meshes with the second gear 106, and the size of the first gear 105 is the same as that of the second gear 106. This ensures that the two lead screws 103 rotate in opposite directions while maintaining the consistency of their rotational speeds, thereby improving the rationality of the overall structure during operation and meeting actual usage requirements.

[0029] The winding assembly 11 includes a first bevel gear 111, a second bevel gear 112, a shaped ring 113, a shaped block 114, an auxiliary claw 115, and a spring piece 116. The first bevel gear 111 is fixedly mounted on the end face of the second drive shaft 104. The second bevel gear 112 is rotatably disposed inside the curtain guide rail 7 and meshes with the first bevel gear 111. The shaped ring 113 is fixedly mounted on the auxiliary roller 5. The shaped block 114 is fixedly mounted on the second bevel gear 112. The auxiliary claw 115 is movably disposed on the shaped block 114. The two ends of the spring piece 116 are fixedly connected to the auxiliary claw 115 and the shaped block 114, respectively, which improves the flexibility of the overall device, allows the components to move together, ensures the overall performance, and allows the auxiliary roller 5 to rotate forward on its own without interference from other structures, releasing the upper curtain 1 or the lower curtain 2 on its surface, so as to facilitate the subsequent removal and cleaning of the upper curtain 1 and the lower curtain 2.

[0030] Working principle: The auxiliary roller 5 is set on the curtain rail 7, which is fixed to the curtain frame 6. The upper curtain 1 and the lower curtain 2 slide on the curtain rail 7 through the slider 102 fixedly connected to it. The ends of the upper curtain 1 and the lower curtain 2 are respectively fixed on the two auxiliary rollers 5. The auxiliary rollers 5 are rotatable on the curtain rail 7. The magnetic female part 3 fixed on the upper curtain 1 and the magnetic male part 4 fixed on the lower curtain 2 are magnetically connected and interlocked with each other. At the same time, the decorative panel 8 is also fixed on the curtain frame 6. In actual installation, the width of the curtain frame 6 matches the width of the cabin wall, so that the structure except for the upper curtain 1 and the lower curtain 2 can be hidden in the side wall of the cabin. The decorative panel 8 is set on the surface of the curtain frame 6 to improve the aesthetics. Under the constraints of the curtain frame 6 and the curtain rail 7, the upper curtain 1 or the lower curtain 2 can be restricted from swinging too much during the operation of the ship, thereby eliminating safety hazards.

[0031] In actual operation, when the upper curtain 1 and lower curtain 2 are opened and closed, the extension rod 92 is rotated so that the protruding part of the cam 98 fixed on the extension rod 92 does not contact the ball joint rod 94. The ball joint rod 94 slides inside the turntable 91 through the auxiliary ring 910 fixedly connected to it. The auxiliary ring 910 is further connected to the turntable 91 by the auxiliary spring 99. The turntable 91 is fixed on the end of the first transmission shaft 101. As the cam 98 rotates, under the action of the auxiliary spring 99, the ball joint rod 94 drives the friction block 93 at its end to move away from the decorative panel 8. Sliding prevents the friction block 93 from contacting the friction texture on the decorative panel 8. At this point, the extension rod 92 can be used to drive the turntable 91 and the first drive shaft 101 to rotate. Since the worm gear 109 fixed to the first drive shaft 101 is threadedly connected to the worm wheel 107, and the worm gear 109 is fixed to the second drive shaft 104, this causes the second drive shaft 104 to rotate. The two sliders 102 fixed to the upper curtain 1 or lower curtain 2 are respectively threadedly connected to the two lead screws 103. The sliders 102 are also slidable on the curtain rail 7 and fixed to the second drive shaft 104. The first gear 105 on the 4 meshes with the second gear 106. The second gear 106 is fixed to the end of one of the lead screws 103. The other lead screw 103 is driven by the pulley set 108 to the second drive shaft 104. When the turntable 91 drives the second drive shaft 104 to rotate in the forward direction, the lead screw 103 connected to the second drive shaft 104 via the pulley set 108 rotates synchronously in the forward direction, and the other lead screw 103 will rotate in the opposite direction. Since the two lead screws 103 rotate in opposite directions, the two corresponding sliders 102 will drive the upper curtain 1 and the lower curtain 1 to rotate in opposite directions. Curtain 2 slides in opposite directions to open and close upper curtain 1 and lower curtain 2. After the extension rod 92 is released, under the action of the reset torsion spring 96 connected to the connecting shaft 97 and the connecting seat 95 at both ends respectively, where the connecting shaft 97 is set on the extension rod 92 and the connecting seat 95 is fixed on the turntable 91, the extension rod 92 will return to its initial state. The protrusion on the cam 98 will squeeze the ball head rod 94, pushing the friction block 93 to slide towards the decorative plate 8, so that the friction block 93 contacts and engages with the friction texture on the decorative plate 8 to restrict the rotation of the turntable 91, thereby locking the overall structure.

[0032] During the opening and closing of the upper curtain 1 and the lower curtain 2, the first bevel gear 111 and the second bevel gear 112, which are fixed to the end of the second drive shaft 104, mesh. The second bevel gear 112 is fixedly connected to the shaped block 114, and the shaped ring 113 is fixed to the auxiliary roller 5. An outward-angled auxiliary claw 115 is movably arranged on the shaped block 114, and a spring piece 116 further connects the auxiliary claw 115 and the shaped block 114. The shaped ring 113 has an oblique toothed groove. Therefore, when the turntable 91 drives the second drive shaft 104 to rotate in the forward direction, the upper curtain 1 descends, the lower curtain 2 rises, and the upper curtain 1 closes. When the curtains are raised, the irregular block 114 and the irregular ring 113 rotate in the forward direction, and the auxiliary roller 5 also rotates in the forward direction, releasing the upper curtain 1 or the lower curtain 2 wrapped on the auxiliary roller 5. Meanwhile, the turntable 91 drives the second drive shaft 104 to rotate in the reverse direction, causing the upper curtain 1 to rise and the lower curtain 2 to fall. When the curtains are opened, the irregular block 114 rotates in the reverse direction in sync. At this time, the auxiliary claw 115 will come into contact with the irregular ring 113, causing the irregular ring 113 and the auxiliary roller 5 to rotate in the reverse direction, so as to wrap the fabric accumulated by the upper curtain 1 and the lower curtain 2 as the curtains are opened around its surface, thereby achieving roll-up and avoiding interference between the components.
