Problems solved by technology

However, the device adopts the direct hinge connection between the door and the shell, and the centering positioning has extremely high requirements for installation, and it will cause unilateral extrusion deformation and wear of the door and the shell, and the sealing effect will deteriorate; the opening and closing action is controlled by several The hinged connecting rod is realized, and it is easy to deform after long-term operation, so that the locking force of the hatch door is not enough, resulting in poor sealing effect

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as Figure 1 to Figure 12 As shown, a kind of hatch locking device used on the deep-sea pressure hull of the present invention includes a hatch handle 2 positioned at the hatch 1 and an interior handle positioned inside the cabin, the interior handle and the hatch handle It is fixedly connected by the rotating shaft 3. One end of the rotating shaft 3 positioned outside the cabin is a square hole, which cooperates with the square joint that the hand wheel 4 outside the cabin is provided with. One end of the rotating shaft 3 located in the cabin is a square joint, which cooperates with the square hole provided by the handle 18 in the cabin, and is locked by the spherical pin 26 . The spherical pin 26 is located in the conical hole that one side of the square joint offers, and is connected with the shaft by the spring 25. A stepped contact is adopted betwee...

Abstract

The invention discloses a hatch door locking device used on a deep-sea pressure hull, which comprises a hatch handle and an inside handle, the inside handle and the outside handle are fixedly connected by a rotating shaft, and the rotating shaft is mounted on the inside handle. One side is equipped with an end cover fixed on the hatch, steps are provided at both ends of the rotating shaft, a traction nut is threaded on the rotating shaft, the traction nut is fixedly connected with the base of the slide rail, and the base of the slide rail is sleeved on the shaft, The side of the slide rail base is evenly provided with at least two grooves, and a pulley is arranged in the groove, the pulley is installed on one end of the locking rod, the locking rod is hinged on the hatch, and the other end of the locking rod is free to move, through The movement drives one end of the locking rod to move, the other end of the locking rod is locked on the housing, and the hatch is installed on the housing through a four-bar device. The invention can ensure that the locking force of the cabin door is balanced through the action of the locking lever, and the cabin door and the casing are completely extruded and contacted, and the locking of the cabin door is finally completed, and the operation is reliable.

Description

technical field [0001] The invention relates to a hatch door locking device used on a deep-sea pressure-resistant shell, belonging to the field of diving equipment. Background technique [0002] Abyssal science and technology is the latest frontier of deep-sea science. Manned submersibles are an important carrier of abyssal science and technology. As one of the important components of submersibles, the hatch device is related to the safety of submersibles and divers, and plays a pivotal role. [0003] Existing hatch devices are divided into two categories: one is the hinged hatch and shell, which is squeezed by a briquetting block to lock the hatch. The structure is simple, but long-term operation will lead to unilateral extrusion of the hatch and shell. Compression deformation and wear, so that the door and the shell can not be completely squeezed into contact, and eventually lead to poor sealing effect of the door; the other is that the door and the shell are locked by pin...
