[0001] The invention belongs to the technical field of underwater submersibles, and in particular relates to a door locking device of an underwater vehicle. Background Art

[0002] With the continuous improvement of underwater combat systems, underwater submersible technology is also booming. In order to adapt to different types of loads, Sierra hatches are gradually used in the field of underwater submersibles. However, there are relatively few products with the function of locking Sierra hatches after closing in the field of underwater submersibles. Therefore, it is necessary to propose a locking device for underwater submersible hatches. Summary of the invention

[0003] The purpose of the present invention is to provide a locking device suitable for the underwater submersible cabin door in order to meet the demand for locking the underwater submersible cabin door.

[0004] The technical solution of the present invention is: a locking device suitable for underwater submersible cabin doors, comprising: a left cabin door locking seat and a right cabin door locking seat respectively installed on the left and right cabin doors, a sealing drive device, a locking pin, a push nut, and a pin guide seat.

[0005] The sealing drive device is connected to the locking pin by pushing the nut; under the drive of the sealing drive device, the locking pin can move forward and backward.

[0006] The left door locking seat and the right door locking seat are respectively provided with latch holes; when the door is fully closed, the latch holes on the left door locking seat and the right door locking seat remain coaxial with the guide holes of the latch guide seat, and the sealing drive device pushes the locking pin forward by pushing the nut, so that the front part of the locking pin passes through the guide holes of the left door locking seat, the right door locking seat and the latch guide seat at the same time to achieve locking.

[0007] When the door is to be opened, the sealing drive device pulls the locking pin backward by pushing the nut, so that the front part of the locking pin only passes through the guide hole of the pin guide seat, but not through the left door locking seat and the right door locking seat.

[0008] In the above solution, specifically, the sealing drive device is fixed on a drive device fixing seat, and the drive device fixing seat is fixed on the underwater submersible body.

[0009] In the above scheme, specifically, the sealing drive device is a sealing pressure-resistant structure, which can realize underwater operation. The sealing drive device is equipped with a linear motor, which is easy to control and can realize linear reciprocating motion.

[0010] In the above scheme, specifically, the locking pin is installed on the driving device fixing seat through the pin bushing II; the front part of the locking pin passes through the guide holes of the pin bushing I and the pin guide seat, and the pin bushing I and the pin guide seat are both installed on the underwater submersible body, and the guide holes of the pin bushing I and the pin guide seat are coaxial.

[0011] On the basis of the above scheme, further, rubber material is provided in the pin holes on the left door locking seat and the right door locking seat, which effectively isolates the left door locking seat, the right door locking seat and the rigid contact with the front part of the locking pin, and can play a shock-absorbing role.

[0012] Beneficial effects:

[0013] (1) The present invention is applicable to the locking function of the plug-type hatch of an underwater submersible, and can solve the problem of insufficient locking after the hatch of the underwater submersible is closed and the vibration problem after the hatch is closed. It has the advantages of simple control, compact structure, and easy installation and disassembly.

[0014] (2) In the present invention, rubber material is provided in the pin holes on the left door locking seat and the right door locking seat, which effectively isolates the left door locking seat and the right door locking seat from the rigid contact with the front part of the locking pin, and can play a shock-absorbing role.

[0015] (3) The sealing drive device in the present invention is internally provided with a linear motor, which is easy to control and can realize linear reciprocating motion; at the same time, the sealing drive device is a sealed pressure-resistant structure and can realize underwater operation.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] See attached Figure 1The present embodiment provides a locking device suitable for the hatch of an underwater submersible, including: a left hatch locking seat 7 and a right hatch locking seat 6 respectively installed on the left and right hatches, a sealing drive device 1, a drive device fixing seat 8, a locking pin 3, a pushing nut 9, a pin bushing Ⅰ4, a pin bushing Ⅱ2, and a pin guide seat 5.

[0022] The sealed drive device 1 is fixed on the drive device fixing seat 8, and the drive device fixing seat 8 is fixed on the underwater submersible body. The sealed drive device 1 is a sealed pressure-resistant structure, which can realize underwater work. The sealed drive device 1 is equipped with a linear motor, which is easy to control and can realize linear reciprocating motion.

[0023] The locking latch 3 is installed on the drive device fixing seat 8 through the latch bushing II 2; the sealing drive device 1 is connected to the locking latch 3 through the push nut 9; the front part of the locking latch 3 passes through the guide holes of the latch bushing I 4 and the latch guide seat 5, and the latch bushing I 4 and the latch guide seat 5 are both installed on the underwater submersible body, and the guide holes of the latch bushing I 4 and the latch guide seat 5 are coaxial. Under the drive of the sealing drive device 1, the locking latch 3 can move forward and backward.

[0024] See attached Figure 2 , the left door locking seat 7 and the right door locking seat 6 are respectively provided with latch holes; when the door is fully closed, the latch holes on the left door locking seat 7 and the right door locking seat 6 remain coaxial with the guide hole of the latch guide seat 5, and the sealing drive device 1 pushes the locking latch 3 forward by pushing the nut 9, so that the front part of the locking latch 3 passes through the guide holes of the left door locking seat 7, the right door locking seat 6 and the latch guide seat 5 at the same time to achieve locking.

[0025] See attached Figure 3 When the door is to be opened, the sealing drive device 1 pulls the locking pin 3 backward by pushing the nut 9, so that the front part of the locking pin 3 only passes through the guide hole of the pin guide seat 5, but does not pass through the left door locking seat 7 and the right door locking seat 6.

[0026] On the basis of the above scheme, further, rubber material is provided in the pin holes on the left door locking seat 7 and the right door locking seat 6, which effectively isolates the left door locking seat 7 and the right door locking seat 6 from the rigid contact with the front part of the locking pin 3, and can play a shock-absorbing role.

[0027] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
