Problems solved by technology

[0002] At present, in order to improve the comfort of the ship, the cabin doors and other doors in the ship are often filled with sound-insulating or sound-absorbing materials to block the transmission of noise, which effectively enhances the noise reduction effect and improves the comfort of passengers. However, such doors The body only considers the sound insulation or sound absorption of the noise from the outside, and does not consider the noise generated by the door lock, hinge, pulley, etc. during the use of the door itself. When ...

Embodiment Construction

[0021] refer to Figure 1 to Figure 3 , the first embodiment of the present invention, a marine silent door structure, including a door body 10, the door body 10 is provided with a door lock 20, the door lock 20 includes a guide sleeve 22 and a lock slidingly arranged in the guide sleeve 22 The tongue 21, the guide sleeve 22 and / or the lock tongue 21 are provided with a first sound-absorbing portion located on the contact surface between the guide sleeve 22 and the lock tongue 21 or between the guide sleeve 22 and the lock tongue 21, the first sound-absorbing portion For non-metallic material. In the present invention, since the first noise-absorbing part of non-metallic material is set on the contact surface between the lock tongue 21 and the guide sleeve 22 or between the guide sleeve 22 and the lock tongue 21, during the expansion and contraction of the lock tongue 21, it can effectively It avoids harsh noise caused by metal friction, and even in the case of insufficient l...

Abstract

The present invention discloses a marine mute door structure. The structure includes a door body on which a door lock is arranged; the door lock includes a guide sleeve, and a lock tongue in sliding arranged in the guide sleeve; the guide sleeve and/or the lock tongue is provided with a first sound attenuation portion located on the contact surface of the guide sleeve and the lock tongue or between the guide sleeve and the lock tongue; and the first sound attenuation portion is made of a non-metal material. In the present invention, the first sound attenuation portion made of the non-metal material is arranged on the contact surface of the lock tongue and the guide sleeve or between the guide sleeve and the lock tongue, so that harsh noise generated due to metal friction can be effectivelyavoided in the expansion and contraction process of the lock tongue; even in the case of insufficient lubrication, noise self-generated in the use of the structure can be as far as possible reduced,and the marine mute door structure has simple structure, low cost, and convenience to popularize and use.

Description

technical field [0001] The invention relates to the technical field of ships, and particularly designs a ship door structure. Background technique [0002] At present, in order to improve the comfort of the ship, the cabin doors and other doors in the ship are often filled with sound-insulating or sound-absorbing materials to block the transmission of noise, which effectively enhances the noise reduction effect and improves the comfort of passengers. However, such doors The body only considers the sound insulation or sound absorption of the noise from the outside, and does not consider the noise generated by the door lock, hinge, pulley, etc. during the use of the door itself. When the door is used in the initial stage, due to the small deformation of the metal, each The fit of the parts is still relatively accurate, and there is no rust, and the lubrication is sufficient. The noise generated by the door itself is generally very small, and the manufacturer often does not pay...
