Detailed Description of the Preferred Embodiments

[0023] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0024] As Figure 1 shown, a liftable rear deck at the tail of a yacht includes a base 1. The inner side of the base 1 is rotatably connected with a lifting mechanism 2. The upper side of the lifting mechanism 2 is fixedly connected with a lifting plate 3. The upper side of the lifting plate 3 is fixedly connected with two symmetrically distributed enclosure mechanisms 4 in the front and back. The upper side of the lifting plate 3 is provided with a friction pattern 5.

[0025] It should be noted that the friction pattern 5 is used to increase the friction between an object and the lifting plate 3, and to prevent the object from slipping off the friction pattern 5 due to the instability of the bottom when the whole is on the water surface at a relatively high position.

[0026] As shown Figure 3 in the figure, the lifting mechanism 2 includes a fixing plate 24. The upper side of the fixing plate 24 is fixedly connected to the lower side of the lifting plate 3 at positions near the front and rear sides. And two fixing plates 24 are symmetrically distributed front and rear on the lower side of the lifting plate 3. At positions on the right side of the mutually remote sides of the two fixing plates 24 and at positions on the inner front and rear surfaces of the base 1 near the left side, first connecting rods 21 are rotatably connected. At positions on the mutually remote sides of the four first connecting rods 21 away from the lifting plate 3 or the base 1, second connecting rods 22 are rotatably connected. And the other end of the second connecting rod 22 is rotatably connected to the rotating position of the other first connecting rod 21 on the same side near the base 1 and the lifting plate 3. At positions on the left side of the mutually remote sides of the two fixing plates 24 and at positions on the inner front and rear surfaces of the base 1 near the right side, third connecting rods 23 are rotatably connected. And the mutually approaching ends of the first connecting rods 21 and the second connecting rods 22 on the same side are rotatably connected together. On the mutually approaching surfaces of the first connecting rods 21 near the position away from the lifting plate 3, two symmetrically distributed left and right support rods 25 are rotatably connected. On the mutually approaching sides of the support rods 25, two symmetrically distributed front and rear hydraulic telescopic rods 26 are fixedly connected.

[0027] It should be noted that a parallelogram is formed between the first connecting rod 21 and the second connecting rod 22, and a triangle is formed between the first connecting rod 21 and the third connecting rod 23 on the same side. When the hydraulic telescopic rod 26 contracts, the two support rods 25 approach each other, which makes the angle formed between the first connecting rod 21 and the third connecting rod 23 increase, resulting in the lifting of the lifting plate 3. The second connecting rod 22 is used to increase the strength between the two first connecting rods 21 on the same side and at the same time keep the two first connecting rods 21 always in a parallel state.

[0028] As shown Figure 3 in the figure, the first connecting rod 21 and the third connecting rod 23 have the same length, and the length of the first connecting rod 21 is greater than the length of the left and right sides of the hydraulic telescopic rod 26 in the horizontal direction.

[0029] It should be noted that due to the length setting of the first connecting rod 21 and the third connecting rod 23, when the included angle formed between the first connecting rod 21 and the third connecting rod 23 is the smallest, the support rod 25 will move to the left and right sides of the fixing plate 24 to avoid interference of the fixing plate 24 on the support rod 25.

[0030] As shown Figure 4 in the figure, the enclosure mechanism 4 includes a rotating seat 41. The lower side of the rotating seat 41 is fixedly connected to the upper side of the lifting plate 3 at positions near the left and right sides of the front and rear sides. And two rotating seats 41 are symmetrically distributed left and right. Inside the two rotating seats 41, rotating rods 42 are rotatably connected. Inside the two rotating rods 42, movable rods 43 are movably sleeved. The upper side of the movable rod 43 is fixedly connected with a support beam 47.

[0031] It should be noted that by rotating the rotating rod 42, the rotating rod 42 can rotate around the rotating seat 41. The rotating seat 41 is U-shaped to limit the rotation range of the rotating rod 42. There are several fixing holes on the rotating rod 42. By relying on the screw, the rotating rod 42 and the movable rod 43 can be fixed to each other.

[0032] As Figure 4 shown, on the side where the two movable rods 43 are close to each other, several linearly distributed first cross bars 44 are fixedly connected, and on the side where the two rotating rods 42 are close to each other, several linearly distributed second cross bars 45 are fixedly connected.

[0033] It should be noted that the first cross bar 44 is used to strengthen the connection relationship between the two movable rods 43, the second cross bar 45 is used to strengthen the connection relationship between the two rotating rods 42, and at the same time, the first cross bar 44 and the second cross bar 45 protect the side surface of the lifting plate 3.

[0034] As Figure 1 、 Figure 5 shown, on the upper side of the lifting plate 3 near the front and rear sides, two symmetrically arranged stoppers 46 are slidably connected, and the lower side of the stopper 46 is fixedly connected to the lifting plate 3 by screws.

[0035] It should be noted that when the stopper 46 is on the side where the two rotating rods 42 on the front and rear sides are close to each other, the rotating rod 42 is fixed and cannot rotate. On the contrary, the rotating rod 42 can rotate.

[0036] The working principle of the utility model is as follows: first, the rotating rod 42 is rotated to make the rotating rod 42 rotate around the rotating seat 41. The rotating seat 41 is U-shaped to limit the rotation range of the rotating rod 42. The rotating rod 42 is provided with a plurality of fixing holes. The rotating rod 42 and the movable rod 43 can be fixed by means of a screw. The first cross bar 44 is used to strengthen the connection between the two movable rods 43. The second cross bar 45 is used to strengthen the connection between the two rotating rods 42. At the same time, the first cross bar 44 and the second cross bar 45 prevent the side of the lifting plate 3 from being damaged. When the stopper 46 is located at the side where the two rotating rods 42 on the front and rear sides are close to each other, the rotating rod 42 is fixed and cannot be rotated. On the contrary, the rotating rod 42 can be rotated. By rotating the rotating rod 42, the rotating seat 41 can be rotated ninety degrees, so that the whole is in a horizontal state, so as to reduce the height of the enclosure mechanism 4 protruding from the lifting plate 3 as much as possible, which is convenient for the storage of the whole. At the same time, the movable rod 43 and the rotating rod 42 are connected to each other, so that the total length of the rotating rod 42 and the movable rod 43 can be increased, and the protection height can be increased as much as possible. Finally, a parallelogram is formed between the first connecting rod 21 and the second connecting rod 22, and a triangle is formed between the first connecting rod 21 and the third connecting rod 23 on the same side. When the hydraulic telescopic rod 26 contracts, the two support rods 25 move closer to each other, which increases the angle formed between the first connecting rod 21 and the third connecting rod 23, causing the lifting plate 3 to rise. The second connecting rod 22 is used to increase the strength between the two first connecting rods 21 on the same side, and at the same time, the two first connecting rods 21 are always in a parallel state. The length setting of the first connecting rod 21 and the third connecting rod 23 causes When the angle formed between the first connecting rod 21 and the third connecting rod 23 is minimized, the support rod 25 will move to the left and right sides of the fixed plate 24 to avoid interference of the fixed plate 24 with the support rod 25. The hydraulic telescopic rod 26 will contract to cause the lifting plate 3 to move upward. Relying on the cooperation of the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23, when the lifting plate 3 rises, the rotation positions of the first connecting rod 21 and the third connecting rod 23 and the base 1 or the hydraulic telescopic rod 26 can remain unchanged. Compared with the traditional ordinary scissor-type connecting rod assembly, the overall rise is smoother.
