Sound-proof door structure

Abstract

The invention relates to a sound-proof door structure, which comprises a door frame and a door plate, wherein an inner arc surface is arranged on the door frame, a sound-proof bar is arranged on the inner arc surface, and the door plate is provided with an outer arc surface corresponding to the inner arc surface; sealing edge bars are arranged on the top, the left side and the right side of the door plate respectively, a bottom through groove is opened in the bottom part of the door plate, the bottom through groove is internally provided with a horizontally-arranged horizontal rod, a lifting mechanism and a sound absorption bar, the lifting mechanism is located below the horizontal rod, the inner wall of the bottom through groove is symmetrically provided with pull springs connected with the lifting mechanism, and the sound absorption bar is fixed on the bottom part of the lifting mechanism; and one end, close to a hinge, of the horizontal rod is provided with a groove and the other end is provided with a nose, the nose of the horizontal rod reaches out from the side wall of the door plate, the inner wall of the bottom through groove is vertically provided with a positioning rod matched with the groove, the top end of the positioning rod is placed in the groove of the horizontal rod, and the outer wall of the positioning rod is sleeved with a positioning spring matched with thegroove. The sound-proof door is easy to process, easy to manufacture, good in sound-proof performance and obvious in noise reduction.

Description

Technical field: [0001] The invention belongs to the technical field of furniture wooden doors, and in particular relates to a soundproof door structure. Background technique: [0002] In people's life, people generally use light wooden doors to decorate their rooms or offices, but the sound insulation and sealing performance of existing wooden doors are far from meeting people's requirements for private spaces, and with the rapid development of urbanization, urban The level of noise is also increasing, which has become a major hazard to human health, and working in a noisy environment for a long time, noise can cause the balance of cerebral cortex excitation and inhibition, resulting in abnormal reflexes under conditions, resulting in intractable headaches, neurasthenia and neurological insufficiency. At present, in order to improve the sound insulation effect of wooden interior doors, it is usually filled with sound-absorbing cotton, fireproof board or density board, etc....

AI Technical Summary

Problems solved by technology

[0002] In people's life, people generally use light wooden doors to decorate their rooms or offices, but the sound insulation and sealing performance of existing wooden doors are far from meeting people's requirements for private spaces, and with the rapid development of urbanization, urban The level of noise is also increasing, which has become a major hazard to human health, and working in a noisy environment for a long time, noise can cause the balance of cerebral cortex excitation and inhibition, resulting in abnormal reflexes under conditions, resulting in intractable headaches, neurasthenia and neurological insufficiency

At present, in order to improve the sound insulation effect of wooden interior doors, it is usually filled with sound-absorbing cotton, fireproof board or density board, etc. inside the wooden door. During the installation process, in order to reduce the impact of the deformation of the wooden material on the door frame and floor due to drying shrinkage, wet expansion, etc., after the wooden door is installed on the door frame, the general installer will leave a certain gap between the lower end of the door and the ground , and this will affect the sound insulation effect to a certain extent
