The locking rod is eccentrically connected to the locking disc. The transmission mechanism is connected to the locking mechanism and is used to drive the locking disc to rotate. The latch is fixedly connected to the inside of the door frame. The latch has an L-shaped lock hole with an opening at the edge of the latch. During the rotation of the lock disc, the locking rod is pulled into the inside of the lock hole by the locking rod.

[0006] Furthermore, the transmission mechanism includes: A transmission rod is connected to the door body in parallel and rotatably. A worm gear is fixedly connected to the transmission rod, and a worm is meshed with the worm gear. The worm is rotatably connected to the door body and is perpendicular to the door body. The driven rod is parallel to and rotatably connected to the door body, and the lock disc is fixedly connected to the end of the driven rod.

[0007] Furthermore, four driven rods are provided, and two driven rods are provided at each end of the transmission rod. The driven rods and the transmission rod form an I-shaped structure.

[0008] Furthermore, the driven rod and the transmission rod are connected by a bevel gear, and the bevel gear is fixedly connected to the ends of the driven rod and the transmission rod by a key shaft, and the bevel gear on the transmission rod and the driven rod meshes.

[0009] Furthermore, the transmission mechanism also includes a first transmission box and a second transmission box. The first transmission box is located at the worm gear and the worm, with the worm gear and the worm located inside the first transmission box. The second transmission box is located at the bevel gear, with the bevel gear located inside the second transmission box. Both the first transmission box and the second transmission box are box-shaped structures.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1 Figures 1 to 5As shown in the figure, one embodiment of the present invention provides a high-pressure resistant waterproof door. The waterproof door includes a door body 100 and a door frame 200. One side of the door body 100 and the door frame 200 are connected by a hinge 600. A locking mechanism 300 and a transmission mechanism 400 are provided on the door body 100 and the door frame 200, respectively. The locking mechanism 300 and the transmission mechanism 400 are used to lock the door body 100 and the door frame 200. The locking mechanism 300 includes a latch 310 and a latch 320. The latch 310 includes a lock disc 311 rotatably connected to the door body 100. A locking rod 312 is fixedly connected to the locking disc 311. The locking rod 312 is a rod-shaped structure and is eccentrically connected to the locking disc 311. The transmission mechanism 400 is connected to the locking mechanism 300. The transmission mechanism 400 is used to drive the locking disc 311 to rotate. The latch 320 is fixedly connected to the inner side of the door frame 200. The latch 320 is provided with an L-shaped lock hole 321. The lock hole 321 has an opening at the edge of the latch 320. During the rotation of the locking disc 311, the locking rod 312 is pulled into the inner side of the lock hole 321.

[0026] Specifically, in this embodiment, when locking the door body 100 and the door frame 200, the user drives the lock disc 311 to rotate through the transmission mechanism 400. When the lock disc 311 rotates, the lock rod 312 is engaged inside the lock hole 321. Since the lock hole 321 has an L-shaped structure, when the lock rod 312 is engaged inside the lock hole 321, the lock hole 321 blocks the lock rod 312, thereby achieving the locking effect. Furthermore, since the lock rod 312 is driven to rotate by the lock disc 311, the trajectory of the lock rod 312 is circular. When the sealing performance is reduced, increasing the rotation angle of the lock rod 312 can increase the pressing force of the lock rod 312 on the lock hole 321, thereby increasing the counterforce of the latch 320 on the bolt 310, thus increasing the sealing strength of the door frame 200 and achieving the purpose of increasing the sealing performance.

[0027] The high-pressure resistant waterproof door disclosed in this embodiment uses a transmission mechanism 400 to drive the lock disc 311 to rotate, thereby engaging the lock rod 312 into the inner side of the lock hole 321. Since the trajectory of the lock rod 312 is circular, when the sealing performance is reduced, increasing the rotation angle of the lock rod 312 can increase the pressing force of the lock rod 312 on the lock hole 321, thereby increasing the counterforce of the latch 320 on the bolt 310, thus increasing the sealing strength of the door frame 200, achieving the purpose of increasing the sealing performance, and thus maintaining the sealing performance of the waterproof door.

[0028] In this embodiment, both the door body 100 and the door frame 200 are existing technologies. For example, the door body 100 is welded from steel plates and has a hollow internal structure. The door frame 200 is welded from channel steel and has reinforcing ribs in the channel. The door frame 200 is a square frame. A sealing ring is provided on the side of the door body 100 near the door frame 200. When the locking mechanism 300 locks the door body 100 and the door frame 200, the sealing ring is compressed, thereby sealing the door body 100 and the door frame 200.

[0029] In this embodiment, the lock disc 311 is a disc structure, the lock rod 312 is eccentrically connected to the lock disc 311 by interference fit, the lock disc 311 is fixedly connected to the output end of the transmission mechanism 400 by key shaft fit, the lock rod 312 is a round rod structure, the latch 320 is a square block, and the latch 320 is fixedly connected to the inner side of the door frame 200 by bolts.

The driven rod 420 is parallel to and rotatably connected to the door body 100. The transmission rod 410 is movably connected to the door body 100. The transmission rod 410 drives the driven rod 420 to rotate. The lock disc 311 is fixedly connected to the end of the driven rod 420. When the worm gear 450 is rotated, the worm gear 450 drives the worm wheel 440 to rotate. The worm wheel 440 drives the transmission rod 410 to rotate. The transmission rod 410 drives the driven rod 420 to rotate. The driven rod 420 drives the lock disc 311 to rotate, thereby locking or unlocking the door body 100 and the door frame 200.

[0031] The locking disc 311 is fixedly connected to the end of the driven rod 420 via a key shaft.
