[0021] Reference Figure 1 , Figure 2 and Figure 3 The present invention discloses a ship rear deck, including a connecting portion 100, a platform 300, two sets of telescopic mechanisms 400 and two sets of slider assemblies 500, wherein the platform 300 is located at the rear side of the connecting portion 100, and the center of gravity of the platform is on a vertical plane, and the vertical plane is perpendicular to the front-rear direction.

[0022] Among them, the connection part 100 is provided with two guide rails 200 distributed on the left and right, the guide rails 200 are vertically arranged, and two groups of telescopic mechanisms 400 are distributed on the left and right. The upper end of each group of telescopic mechanisms 400 is hinged to the platform 300 through a hinge axis, and the hinge axis is located on a vertical plane. The lower end of the telescopic mechanism 400 is hinged to the connection part 100 and is located on the extension line of the corresponding guide rail 200. The axis of the telescopic mechanism 400 is not parallel to the guide rail 200.

[0023] Further references Figure 4 and Figure 5 Two groups of slider assemblies 500 are installed on the front side of the platform 300. The slider assemblies 500 are slidably connected to the guide rails 200 in a one-to-one correspondence. Specifically, the slider assemblies 500 include a sliding body 510 and a tension block 520. The tension block 520 is detachably connected to the sliding body 510. The sliding body 510 has a cavity 530 extending up and down and having an opening on the front side. The tension block 520 extends into the cavity 530 from the opening of the cavity 530. The tension block 520 and the sliding body 510 jointly embrace the guide rail 200. The position of the tension block 520 relative to the sliding body 510 along the front-to-back direction is adjustable.

[0024] The present invention adopts a lifting floating platform design. The platform 300 is slidably connected to the guide rail 200 on the connecting part 100 through the slider assembly 500 on one hand, and is connected to the connecting part 100 through the telescopic mechanism 400 on the other hand.

[0025] When the telescopic mechanism 400 is extended or retracted, it will drive the slider assembly 500 to slide and rise and fall along the guide rail 200. When the platform 300 needs to stay at a certain height, the telescopic mechanism 400 stops extending or retracting. Since the elastic block 520 and the sliding body 510 jointly embrace the guide rail 200, the pressure and friction of the elastic block 520 and the sliding body 510 on the guide rail 200 can be adjusted by adjusting the position of the elastic block 520 relative to the sliding body 510 along the front and rear directions, and the platform 300 can be prevented from flipping or shaking relative to the guide rail 200. The telescopic mechanism 400, the platform 300 and the guide rail 200 are constructed into a dynamic and stable triangular structure, so that the platform 300 can remain at this height and remain in a horizontal state, which is convenient for people to go into the water and directly lower the lifebuoy or boat to the water surface or raise it to the deck of the ship, meeting multi-functional needs.

[0026] In addition, the slider assembly 500 and the guide rail 200 are easy to assemble, with low space and site requirements. The tension block 520 can be removed from the cavity 530 to release the constraint on the guide rail 200, making installation and maintenance convenient. When the platform 300 is not needed, the platform 300 can be easily removed from the connecting part 100 due to the easy-to-disassemble design of the guide rail 200.

[0027] Reference Figure 2 In some embodiments of the present invention, a bottom frame 310 is installed at the bottom of the platform 300, and two load-bearing beams 320 distributed left and right and extending front and back are installed on the bottom frame 310. A connecting rod 330 is arranged between the two load-bearing beams 320. The upper end of the telescopic mechanism 400 is hinged to the rear end of the load-bearing beam 320, and the slider assembly 500 is installed at the front end of the load-bearing beam 320. The load on the platform 300 itself and the platform 3 can be concentratedly transmitted to the two telescopic mechanisms 400 through the bottom frame 310 and the load-bearing beam 320, so as to play a role in stabilizing the support of the platform 300. Among them, the telescopic mechanism 400 can be a hydraulic cylinder with a large hydraulic support force.

[0028] In some embodiments of the present invention, the connection part 100 is equipped with locking mechanisms at the bottom and top of the guide rail 200, and the locking mechanisms are used to lock the slider assembly 500 at the highest position or the lowest position on the guide rail 200. When the platform 300 is lowered to the lowest position, the position can be locked by the locking mechanism to prevent the platform 300 from shaking up and down when the load on the platform 300 increases or decreases suddenly, thereby ensuring safety; when the platform 300 is raised to the highest position, the upper surface of the platform 300 is flush with the deck of the hull, and the position can be locked by the locking mechanism, so that the platform 300 becomes part of the deck when not in use.

[0029] Reference Figure 4 and Figure 5 In some embodiments of the present invention, the sliding body 510 is provided with a horizontal guide groove 540 extending along the front-to-back direction in the cavity 530, and the horizontal guide groove 540 is recessed in the cavity 530. A guide block 550 is correspondingly protruded on the tension block 520, and the guide block 550 can move forward and backward in the horizontal guide groove 540. Firstly, the pressure and friction of the tension block 520 and the sliding body 510 on the guide rail 200 can be adjusted. Secondly, when the sliding block 510 moves vertically along the guide rail 200, the horizontal guide groove 540 drives the guide block 550 and the tension block 520 to rise and fall together, and can also constrain the tension block 520 in the vertical direction, and also keep the sliding block 510 and the tension block 520 synchronized and consistent in the vertical direction.

[0030] In addition, refer to Figure 4 The slider assembly 500 also includes a fastening block 560 and an adjusting bolt 570. The fastening block 560 is located at the front side of the cavity 530 and is detachably connected to the sliding body 510. A nut 580 is installed on the fastening block 560. The adjusting bolt 570 is screwed together with the nut 580. After one end of the adjusting bolt 570 passes through the nut 580, the tension block 520 is tightened against the guide rail 200 to adjust the pressure between the tension block 520 and the guide rail 200 to prevent the platform 300 from flipping or shaking relative to the guide rail 200.

[0031] Among them, the cross-section of the guide rail 200 is diamond-shaped, and the sliding body 510 and the elastic block 520 are both provided with V-shaped grooves 590 in the area that jointly embraces the guide rail 200. The openings of the two V-shaped grooves 590 are arranged facing each other, and the inner groove walls of the two V-shaped grooves 590 correspond one by one to the side walls of the guide rail 200, thereby increasing the contact area, preventing the slider assembly 500 from twisting or rotating relative to the guide rail 200, and can also play a positioning role during installation.

[0032] In addition, refer to Figure 4 and Figure 5 A wear-resistant sheet 600 is provided between the V-groove 590 and each outer side surface of the guide rail 200. The wear-resistant sheet 600 is installed on the V-groove 590 to prevent damage to the guide rail 200, the sliding body 510 and the tensioning block 520. When the wear-resistant sheet 600 is worn to a certain extent due to long-term use, the tensioning block 520 can be tightened to maintain the pressure between the guide rail 200 and the sliding body 510 within a certain range. The tensioning block 520 is always in a state of clamping the guide rail 200. The tensioning block 520 can also be removed in time and the wear-resistant sheet 600 can be replaced, which makes maintenance very convenient.

[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
