Detailed implementation mode
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] As Figures 1-8 shown, a balanced seaman's bed includes a square-structured bed body 1 with an upper end completely open and arranged on a deck 25, a bed board 2, a balance mechanism, as well as two groups of limit systems and two groups of connecting rod systems that are mirror-symmetrically arranged on both sides of the inner cavity length direction of the bed body 1. The bed board 2 is placed at the upper port of the bed body 1. A middle partition board 2 extending along the bed length direction is vertically arranged in the middle of the inner bottom plate of the bed body 1. A middle partition board opening 201 is provided on the middle partition board 2. The balance mechanism is placed in the inner cavity of the bed body 1. The lower end surface of the balance mechanism is rotatably connected to the upper end of the middle partition board opening 201 left and right. The connecting rod system includes a bed board connecting rod 6, a bed body connecting rod 5, and a balance mechanism connecting rod 4 that are rotatably connected in sequence from beginning to end. The upper end of the bed board connecting rod 6 is rotatably connected to the bed board 2. The middle of the bed body connecting rod 5 is rotatably connected to the inner bottom plate of the bed body 1. The upper end of the balance mechanism connecting rod 4 is rotatably connected to the balance mechanism directly above it; the bed board connecting rod 6 is movably connected to the limit mechanism.
[0027] In some embodiments, the upper end of the bed board connecting rod 6 is rotatably connected to the bed board 2 left and right through an eye plate 20 and a bolt.
[0028] It can be understood that when the ship tilts, the balance mechanism tilts, the balance mechanism drives the balance mechanism connecting rod 4 to move, the balance mechanism connecting rod 4 drives the bed body connecting rod 5, the bed body connecting rod 5 drives the bed board connecting rod 6, and the bed board connecting rod 6 drives the bed board 2 to keep the bed board 2 horizontal.
[0029] Specifically, the balance mechanism includes a balance box 7 with an open part along its midline on the upper end face in its length direction. The upper end of the balance mechanism connecting rod 4 is rotatably connected to the left and right of the balance box 7. A water bag 23 is fixed on the inner bottom plate of the balance box 7. A water inlet pipe 8 and a water outlet pipe 9 are provided on the water bag 23, and valves 21 are provided on both the water inlet pipe 8 and the water outlet pipe 9. In some embodiments, the upper end of the middle partition plate 2 is connected to the outer bottom surface of the balance box through a hinge 17 and a screw 18.
[0030] It can be understood that when the ship tilts, the water bag 23 in the balance box 7 tilts, the balance box 7 drives the balance mechanism connecting rod 4 to move, the balance mechanism connecting rod 4 drives the bed body connecting rod 5, the bed body connecting rod 5 drives the bed board connecting rod 6, and the bed board connecting rod 6 drives the bed board 2, so that the bed board 2 remains horizontal. An opening is made on the middle partition plate 2. When the balance box 7 moves to the maximum working angle, it contacts the middle partition plate 2 located above the opening 201 of the middle partition plate.
[0031] In order to prevent the crew's weight from being too large and exceeding the deployment range of the water bag 23, a plurality of ball compartments 24 are arranged at intervals along the length direction of the bed body 1 between the inner bottom plate of the balance box 7 and the water bag. Two T-shaped limit plates 28 are symmetrically arranged on the ball compartment 24 relative to the midline in its length direction. The lower ends of the two T-shaped limit plates 28 sequentially penetrate through the ball compartment 24 and the bottom plate of the balance box 7, and are both connected to the outer bottom surface of the balance box 7 through two springs 16 arranged in mirror symmetry; A ball 22 is placed between the two T-shaped limit plates 28. On the inner bottom plate of the ball compartment on both sides of the two T-shaped limit plates 28, a cushion plate 26 with an upper end face inclined downward from the edge side to the middle is symmetrically arranged. The lower end of the side surface of the cushion plate 26 close to the T-shaped limit plate 28 forms a certain angle with the lower part of the T-shaped limit plate 28. Through holes are oppositely opened on the two T-shaped limit plates 28. When the T-shaped limit plate 28 is pressed down by the water bag 23 to a certain position, the ball 22 rolls freely in the ball compartment 24. The ball 22 is an iron ball / lead ball. In this embodiment, the inclination angle of the upper end face of the cushion plate 26 is 2-3°, and the angle between the side surface of the cushion plate 26 close to the T-shaped limit plate 28 and the T-shaped limit plate 28 is 45°.
[0032] It can be understood that the T-shaped limit plates 28 arranged on both sides of the ball 22 are means for restricting and releasing the ball 22. When the water bag 23 is filled with water, the pressure of the water bag 23 causes the T-shaped limit plate 28 to move downward, and the opening of the T-shaped limit plate 28 is parallel to the ball 22, and the ball 22 can roll freely. When the water bag 23 is empty, the spring 16 at the lower end of the T-shaped limit plate 28 causes the T-shaped limit plate 28 to reset, and the opening of the T-shaped limit plate 28 is not parallel to the ball 22, restricting the movement of the ball 22.
[0033] In some embodiments, the upper end surface of the middle partition plate abuts or does not contact the inner bottom surface of the bed board.
[0034] Specifically, the limiting system includes a limiting column 12 with a hollow structure. Inside the limiting column 12, a limiting plate 14 and a limiting block 13 are arranged at intervals from bottom to top. At the top end of the limiting column 12, there is a sealing plate 27. Opposite circular holes are formed in the limiting plate 14, the limiting block 13, and the sealing plate 27. The diameter of the circular holes is larger than the diameter of the bed board connecting rod 6. The bed board connecting rod 6 is placed inside the limiting column 12 and sequentially passes through the limiting plate 14, the limiting block 13, and the sealing plate 27. On the bed board connecting rod 6 above the limiting block 13, there is a spherical ball with a diameter larger than its own diameter, and the diameter of the spherical ball is larger than the diameter of the circular hole; on the two side plates of the limiting column 12 parallel to the middle partition plate 2, limiting block tracks 121 for the limiting block 13 to move along the length direction and the up and down direction of the bed body 1 are symmetrically arranged in a mirror image. The two ends of the limiting block 13 are placed inside the limiting block tracks 121. In some embodiments, the limiting block track 121 is a right-angled U-shaped track with an opening facing the width direction of the bed body 1.
[0035] It can be understood that the limiting block 13 is used to clamp the middle spherical ball of the bed board connecting rod 6 to achieve a fixed state in the non-working state, and the limiting plate 14 is used to limit the upper and lower limit spaces of the movement of the bed board connecting rod 6. The limiting column 12 is a columnar three-dimensional space, which is used to provide a working space for the bed board connecting rod 6, the limiting block 13, and the limiting plate 14 to ensure the movement of the bed board connecting rod 6 in the vertical direction.
[0036] Further, the limiting column 12 is formed by three plates vertically arranged in the inner cavity of the bed body 1 and the side wall in the length direction of the bed body 1. One end of the bed body connecting rod 5 vertically extends into the lower part inside the limiting column 12; the limiting system further includes two L-shaped limiting stools 15, and the L-shaped limiting stools 15 can be movably placed in the lower part inside the limiting column 12. The limiting stools 15 are used to clamp the end of the bed board connecting rod 6 in the non-working state to realize the stability of the overall system.
[0037] Further, a through hole is formed upward from the deck 25 in the lower part of the side wall in the length direction of the bed body 1 that encloses the limiting column 12. The height of the through hole is lower than the height of the L-shaped limiting stool 15, and the width of the through hole is larger than the width of the L-shaped limiting stool 15.
[0038] During use, the L-shaped limiting stools 15 are removed, the limiting plate 14 is released to the lowest position, water is put into the water bag, and the crew lies on the bed board. When not in use, the water is drained, the L-shaped limiting stools 15 are moved to below the connection of the bed body connecting rod 5 and the bed board connecting rod 6, and the limiting plate 14 is moved to the highest position. The arrangement of the through holes on the bed body 1 facilitates the storage of the L-shaped limiting stools 15.
[0039] Further, the bed body link 5 is horizontally placed at the lower part of the inner cavity of the bed body 1. Two supports 19 are vertically fixed on the inner bottom plate of the bed body 1. The two supports 19 are symmetrically arranged with respect to the midline in the length direction of the bed body 1. The upper ends of the two supports 19 are rotatably connected to the left and right of the bed body link 5; Springs 16 are connected between the lower parts of both ends of the bed body link 5 and the inner bottom plate of the bed body 1.
[0040] Further, long waist circular holes 51 extending along the length direction are formed at both ends of the bed body link 5. Both ends of the bed body link 5 are rotatably connected to the bed plate link 6 and the balance mechanism link 4 through bolts 11 passing through the long waist circular holes 51. A sliding sleeve 10 is sleeved outside the bolt 11, and both ends of the sliding sleeve 10 pass through the long waist circular holes 51; The two springs 16 are located directly below the two long waist circular holes 51.
[0041] It can be understood that when the link system moves, the required length between the balance mechanism link 4 and the bed plate link 5 increases. Therefore, waist circular holes are formed at both ends of the balance mechanism link 4 to supplement the required length. In order to ensure free sliding at the connection, a rolling sleeve is sleeved outside the screw to ensure free sliding at the connection.
[0042] Those of ordinary skill in the art should understand that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
