Description

Sound insulating seal door-plate

Technical field

This utility model relates to life staying idle at home articles for use technical field, is specifically related to a kind of sound insulating seal door-plate.

Background technology

Along with the high speed development of industrialization and urbanization, the pollution level of city noise is inevitably exacerbated, has become as to the mankind one and endangers greatly. Noise pollution and water pollute, atmospheric pollution is regarded as in world wide three main Environmental Problems. Noise can cause multiple disease, and noise, except damage audition, also can cause other damages to person. That noise can also cause is in a disturbed state of mind, be nervous, palpitating speed and blood pressure increase. Noise also can make the saliva of people, gastric secretion reduce, and gastric acid reduces, thus being susceptible to suffer from gastric ulcer and duodenal ulcer. Some industrial noise survey results are pointed out, the iron and steel individual when high noisy is higher than the individual blood circulation sickness rate under quiet condition with machine shop individual in work. Under strong sound, the people of hypertension is also many. Many people think, the noise in the life of 20th century is to cause one of cardiopathic reason. Work under noisy environment for a long time, function of nervous system be will also result in obstacle. Human body under laboratory condition is it is demonstrated experimentally that under noise effect, people's brain wave can change. Noise can cause the balance that cerebral cortex is excited and suppresses, thus causing the exception of reflection under condition. Some patients can cause intractable headache, neurasthenia and cranial nerve insufficient. Symptoms has much relations with the noise intensity contacted. Such as, when noise is when 80-85 decibel, often very emotional, feel fatigue, headache is many in temporo frontal region; During 95-120 decibel, operation individual often fore head passivity pain, and with emotional, dyssomnias, dizziness, hypomnesis; Not only cause otopathy when noise arrives by force 140-150 decibel, and occur fear and whole body nervous system tonicity to increase. So, how to reduce or insulating noise is urgent problem.

In prior art, the door-plate of timber is generally the plate that monoblock log is made, and there is the deficiency such as stress difference, easily cracking, soundproof effect difference, it is impossible to meet people's requirement to sound insulation and sound-absorbing.

Utility model content

This utility model provides a kind of sound insulating seal door-plate, with the problem solving the sound insulating seal weak effect that prior art exists.

This utility model includes door-plate main body, solves the employed technical scheme comprise that door-plate main body of its technical problem and by original plank and is embedded in the abatvoix within original plank and forms, and original plank side and doorframe junction arrange a draw-in groove.

This utility model is by arranging a draw-in groove in door-plate and doorframe junction, this draw-in groove can fit tightly with the projection of doorframe when door-plate closes, increase the contact area of door-plate and doorframe, thus greatly reducing the leakage audio fruit of door-plate and doorframe, inside door-plate, abatvoix is set simultaneously, also contribute to the raising of door-plate sound insulating seal, there is simple in construction, the advantage that non-maintaining and sound insulating seal is excellent.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is use view of the present utility model.

1 original plank, 2 abatvoixs, 3 draw-in grooves, 4 doorframes in figure.

Detailed description of the invention

As depicted in figs. 1 and 2, a kind of sound insulating seal door-plate, including door-plate main body, door-plate main body is by original plank 1 and is embedded in the abatvoix 2 original plank 1 within and forms, and original plank 1 side and doorframe 4 junction arrange a draw-in groove 3.

This utility model is by arranging a draw-in groove in door-plate and doorframe junction, this draw-in groove can fit tightly with the projection of doorframe when door-plate closes, increase the contact area of door-plate and doorframe, thus greatly reducing the leakage audio fruit of door-plate and doorframe, inside door-plate, abatvoix is set, it helps the raising of door-plate sound insulating seal simultaneously.

Claims (1)

1. a sound insulating seal door-plate, including door-plate main body, is characterized in that door-plate main body by original plank and is embedded in the abatvoix within original plank and forms, and original plank side and doorframe junction arrange a draw-in groove.
