Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

It should be understood that the terms "first", "second", etc. are used herein to describe various information, but the information should not be limited to these terms, and these terms are only used to distinguish one type of information from another. For example, "first" information may also be referred to as "second" information, and "second" information may also be referred to as "first" information without departing from the scope of the present invention.

As shown in fig. 1 to 3, an embodiment of the present invention provides a marine doorsill, including a doorsill body 1, an edge of the doorsill body 1 is provided with an extension portion 11, the extension portion 11 is provided with two or more than two, and each edge of the doorsill body 1 close to a door frame 2 is provided with at least one extension portion 11, in the embodiment of the present invention, each edge of the doorsill body 1 connected to the doorsill 2 is provided with one extension portion 11; in addition, the extension part 11 is connected with the door frame 2 through a fastener 12, and the threshold body 1 is detachably connected with the door frame 2.

Based on the structure, the threshold body 1 is fixed on the door frame 2 through the extension part 11 and the fastener 12 at ordinary times for guaranteeing the normal operation of ships, when the ship door structure where the threshold body 1 is located needs to pass through large-scale equipment or mass materials, the fastener 12 is removed, and the threshold body 1 is taken down from the door frame 2, so that the normal transportation of the equipment and the materials can be guaranteed. So, the design of detachable threshold had both satisfied the standard requirement in height, also can make things convenient for personnel's walking and goods to pass through the mode of demolising the threshold body temporarily under the special circumstances, has improved the practicality, and extension 11 is equipped with a plurality ofly, and the stability of assurance threshold body that can furthest can not appear the condition that threshold body 1 drops, and the simple structure of threshold body 1 simultaneously, easily preparation, ann tear open also very conveniently.

The extension 11 is fixed to the door frame 2 by a fastener 12, which sufficiently secures the stability of the doorsill body 1. In the embodiment of the invention, the fastening piece 12 is preferably a bolt and a butterfly nut, and has the advantages of simple structure, readily available raw materials and contribution to reducing the cost.

As shown in fig. 1 to 3, an embodiment of the present invention further provides a marine door structure, which includes a threshold body 1, a door frame 2, and a door body 3, where the door body 3 is disposed on the top of the threshold body 1, and shares the door frame 2 with the threshold body 1.
