[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a marine turnover platform with a locking device comprises a platform, a fixed pile 2 and a locking device. The platform comprises a bottom plate 11, one side of the bottom plate 11 is connected to the fixed pile 2 by a hinge, and a folding connecting rod 12 is arranged between the bottom plate 11 and the fixed pile 2; the folding connecting rod 12 comprises a first connecting rod 121, a second connecting rod 122 and a connecting hinge 123; the first connecting rod 121 is hinged to the bottom plate 11, the second connecting rod 122 is hinged to the fixed pile 2, the first connecting rod 121 and the second connecting rod 122 are hinged to the fixed pile 2, and the first connecting rod 121 and the second connecting rod 122 are hinged to the fixed pile 2. 122 is connected by a connecting hinge 123; the locking device includes a movable locking assembly and a locking groove 4; the movable locking assembly includes a locking tooth 31, a movable shaft 32, a connecting rod 33, a counterweight 34 and a pull ring 35; the connecting rod 33 is rotatably fixed to the second connecting rod 122 through the movable shaft 32, the locking tooth 31 and the pull ring 35 are respectively arranged at both ends of the connecting rod 33, the counterweight 34 is fixedly connected to the connecting rod 33 and is on the same side as the pull ring 35; the locking groove 4 is arranged on the first connecting rod 121;

[0021] When the platform is in a fully unfolded state, the counterweight block 34 is higher than the position of the locking tooth 31. The counterweight block 34 falls downward under the action of gravity, driving the locking tooth 31 on the other side of the connecting rod 33 to move upward and just engage with the locking groove 4. The locking tooth 31 is fixed with the locking groove 4, and the first connecting rod 121 and the second connecting rod 122 are in a locked state; when the platform needs to be folded, pull the pull ring 35 to drive the locking tooth 31 to disengage from the locking groove 4 to unlock it.

[0022] In actual application, the connecting hinge 123 includes a rotating shaft 123-a arranged on the first connecting rod 121 and a movable hole 123-b arranged on the second connecting rod 122. Therefore, combined with the actual design of the connecting hinge 123, in order to prevent interference between the locking device and the first connecting rod 121 and the second connecting rod 122 when the platform is folded, the rotating shaft 123-a protrudes from the surface of the second connecting rod 122, and the locking groove 4 is arranged on the rotating shaft 123-a.

[0023] In actual applications, a magnetic alignment block 311 is provided in the locking tooth 31. Furthermore, a magnetic alignment block 311 can also be provided at the corresponding position in the locking groove 4. When the counterweight block 34 drives the locking tooth 31 to engage with the locking groove 4 due to gravity, the magnetic alignment block 311 can assist in alignment and fixation.

[0024] The movable locking assembly also includes a limit block 36 for limiting the range of motion of the connecting rod 33. A set of limit blocks can be provided at both ends of the connecting rod 33 to limit the range of motion of the connecting rod 33 toward the inside and outside respectively.

[0025] The movable hole 123 - b is a waist-shaped hole, which provides a movable gap for the rotating shaft 123 - a.

[0026] Advantages of the utility model:

[0027] A locking device consisting of locking teeth, locking grooves, a movable shaft, a connecting rod, a counterweight and a pull ring is arranged on the folding connecting rod; when the platform is in a fully unfolded state, the counterweight is higher than the position of the locking teeth, and the counterweight falls downward under the action of gravity, driving the locking teeth on the other side of the connecting rod to move upward and just combine with the locking groove. The locking teeth and the locking groove are fixed in cooperation, and the first connecting rod and the second connecting rod are in a locked state, which can reinforce the folding connecting rod, increase the supporting force and reduce the shaking effect; when the platform needs to be folded, pull the pull ring to drive the locking teeth to disengage from the locking groove for unlocking.
