[0009] To make the purpose, content and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below.

[0010] The present invention proposes a connecting locking device, which includes a rotary motor 1, an upper cabin fixing plate 2, an upper connecting seat 3, a lower cabin fixing plate 4, a lower connecting seat 5, a locking pin 6, and an adjusting pad 7.

[0011] The upper hull fixing plate 2 is welded to the upper hull, and the upper connecting seat 3 is bolted to the upper hull fixing plate 2; the rotary motor 1 is bolted to the upper connecting seat 3.

[0012] The lower hull fixing plate 4 is welded to the lower hull, and the lower connecting seat 5 is bolted to the lower fixing plate 4. An adjusting shim 7 is installed between the lower connecting seat 5 and the lower hull fixing plate 4 to adjust the hull manufacturing tolerance. The locking pin 6 is installed with a gap between the upper rotary motor 1 and the upper connecting seat 3, and is connected to the output end of the upper rotary motor 1. The upper rotary motor 1 drives the locking pin 6 to rotate.

[0013] The lower end of the locking pin 6 is a tapered structure for contacting the lower connecting seat 5. The outer circle of the locking pin 6 is provided with three petal structures, and the inner wall of the central hole of the lower connecting seat 5 is provided with three petal structures.

[0014] The tapered structure at the end of the locking pin 6 has a guiding function and can achieve automatic alignment. The rotary motor 1 presets a specific angle for the locking pin 6 to ensure that the three petal structures of the locking pin 6 can pass through the three petal structures of the lower connecting seat 5.

[0015] The locking post 6 and the lower connecting seat 5 both feature a specific angle design with their three petal structures.

[0016] The output end of the rotary motor 1 adopts a cross-pin structure for engaging with the top of the locking pin 6.

[0017] Three support blocks are evenly distributed on the inner wall of the upper connecting seat 3 to limit the locking pin 6 in the vertical direction.

[0018] The connection process of the locking device is as follows: When the upper hull to be connected descends, the tapered end of the locking pin 6 contacts the lower connecting seat 5. The tapered end of the locking pin 6 has a guiding function, enabling automatic alignment. The rotary motor 1 presets a specific angle for the locking pin 6, ensuring that the three petal structures of the locking pin 6 can pass through the three petal structures of the lower connecting seat 5. After the upper hull has descended, the rotary motor 1 rotates, driving the locking pin 6 to rotate via the cross pin structure on the rotary motor 1. Both the three petal structures of the locking pin 6 and the three petal structures of the lower connecting seat 5 are designed with a specific angle, achieving connection between the upper and lower hulls as the locking pin 6 rotates. The rotary motor 1 has a brake function, which, after locking, acts as a brake to prevent loosening.

[0019] The process of releasing the connecting locking device is as follows: the cross pin structure on the rotating motor 1 drives the locking pin 6 to rotate. When the three petals of the locking pin 6 rotate to the gap between the three petals of the lower connecting seat 5, the connecting locking device can be released.

[0020] The tapered structure at the end of the locking pin has a guiding function during contact with the lower connection, enabling automatic alignment, making operation easier and improving locking efficiency.

[0021] Both the locking pin and the lower connecting seat adopt a three-petal structure design, with each petal having a specific angle. The locking action is completed by rotating the locking pin. Compared with traditional threaded connections, it has lower requirements for the machining precision of the housing and is easier to automate using a rotary motor.

[0022] This invention has the characteristics of being able to adapt to certain manufacturing deviations during assembly, and using an electric locking method to prevent loosening and for easy operation.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
