Embodiment Construction

[0025] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, characteristics and effects of the watertight door opening structure proposed according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. , as detailed below.

[0026] Such as figure 1 and figure 2 As shown, a watertight door opening structure of the present invention includes a door frame 1, a door body 2, a first connecting rod 3, a second connecting rod 4, a sliding bracket 5, a rail frame 6, a telescopic connection assembly 7 and a hydraulic drive device 8.

[0027] The door body 1 moves and opens along the upper and lower sides of the door frame 2, such as figure 1 As shown, the opening direction of the door body described in this document is described according to the upper and lower sides.

[0028] The guide rail fra...

Abstract

The invention relates to a watertight door opening structure and belongs to the technical field of ships. The watertight door opening structure comprises a door frame, a door body, a first connecting rod, a second connecting rod, a sliding support, a guide rail frame and a hydraulic driving device. The upper edge and the lower edge of the door body are hinged to the first connecting rod and the second connecting rod. The other end of the first connecting rod and the other end of the second connecting rod are hinged to the sliding support which slides on the guide rail frame. Idler wheels are arranged on the first connecting rod and can roll in and out of a sliding groove of the guide rail frame. The second connecting rod is connected with the hydraulic driving device through a telescopic connecting assembly. A limiting bumping block is arranged on the sliding support. At the moment that the door body is opened, the first connecting rod drives the door body to swing, so that sealing rubber is disconnected with a rubber compressing strip on the door frame, and the sliding support drives the door body to move along the guide rail frame till the door frame reaches a final opening position. According to the watertight door opening structure, a watertight door can be opened through one driving device, the cost is effectively reduced, and the reliability of the watertight door is improved.

Description

technical field [0001] The invention relates to an opening structure of a watertight door, which belongs to the technical field of ships. Background technique [0002] Ship is a general term for all kinds of ships, which are used to sail or park in waters for transportation or operation. They have different technical performances, equipment and structural types according to different use requirements. With the advancement of science and technology, ship materials are constantly updated, and the development of ships can more and more meet people's various needs. Among them, the watertight door on the ship requires good water sealing performance. [0003] Because the door body of the watertight door needs to be provided with a sealing rubber, which is compressed between the sealing rubber and the rubber pressing strip on the door frame, thereby the airtightness of the watertight door can be realized. Therefore, the existing watertight door opening method is to use power to p...
