Description
本發明是關於可防止在內部收容之噪音源的噪音從開口部向外部洩漏之隔音封裝件,特別是關於隔音封裝件所具備的門之隔音構造。The present invention relates to a soundproof package that can prevent noise from a noise source housed inside from leaking from an opening to the outside, and particularly relates to a soundproof structure of a door provided in the soundproof package.
以往,基於效率性等優異的理由,螺旋壓縮機在各種領域被利用著。在這樣的螺旋壓縮機,會從機械部分產生超過100dB的噪音。因此,對於螺旋壓縮機,為了保障作業者的工作環境,基於隔音之目的一般是將機械部分用殼狀的隔音封裝件包圍。In the past, screw compressors have been used in various fields for reasons such as excellent efficiency. In such a screw compressor, noise exceeding 100dB is generated from the mechanical part. Therefore, for the screw compressor, in order to protect the working environment of the operator, the purpose of sound insulation is generally to surround the mechanical part with a shell-shaped sound insulation package.
此外,縱使在將螺旋壓縮機的周圍用隔音封裝件包圍的情況,為了確保機械部分的組裝作業、維護作業的方便性,必須在隔音封裝件設置開口部。而且,維護作業等結束後為了能將開口部封閉,是在開口部設置門、蓋。In addition, even when the screw compressor is surrounded by a soundproof package, it is necessary to provide an opening in the soundproof package in order to ensure the convenience of assembly work and maintenance work of the mechanical part. Furthermore, in order to close the opening after maintenance work, etc., a door and a cover are provided in the opening.
然而,縱使設置門、蓋,仍無法消除從開口部洩漏的噪音。這是因為,若門的固定方法不穩定,或在門的周圍、蓋的周圍只要有些微的高低差存在,會在該門、蓋的周圍和主體之間產生間隙,而使門、蓋的隔音性能降低。However, even if the door and cover are provided, the noise leaking from the opening cannot be eliminated. This is because if the method of fixing the door is unstable, or if there is only a slight difference in height around the door or the cover, there will be a gap between the door, the cover and the main body, and the door and the cover The sound insulation performance is reduced.
於是,在專利文獻1及專利文獻2提出不易產生如此般的隔音性能降低之隔音封裝件。Therefore, Patent Document 1 and
例如,在專利文獻1揭示一種隔音封裝件,不受閉合程度的影響而穩定地將間隙密封,藉此可確實地減少噪音洩漏。上述專利文獻1之隔音封裝件係具備:具有開口部且在內部收納噪音源之主體、封閉開口部之平板狀的門、設置在門的周圍且設置在內部側的面之密封構件。該隔音封裝件具備回折部,該回折部是用於維持使開口部在封閉狀態時之密封構件的厚度比開放狀態時的厚度更薄的狀態,使回折部和主體之框抵接,藉此決定並維持封閉狀態之門和主體的間隔。For example, Patent Document 1 discloses a soundproof package that stably seals the gap without being affected by the degree of closure, thereby reliably reducing noise leakage. The soundproof package of Patent Document 1 described above includes a main body having an opening and accommodating a noise source inside, a flat door that closes the opening, and a sealing member provided around the door and provided on the inner surface. The soundproof package is provided with a folded-back portion for maintaining a state where the thickness of the sealing member when the opening is in the closed state is thinner than that in the open state, and the folded-back portion is brought into contact with the frame of the main body. Determine and maintain the distance between the closed door and the main body.
此外,在專利文獻2揭示一種隔音封裝件,係具有開閉門,能提供可完全制止雨水滲入之殼體的防水構造。In addition,
上述專利文獻2之隔音封裝件,是藉由被可旋轉地支承之門使殼體主體的開口部開閉,在該該開口部的周圍形成有突條,在前述門的內面設置被前述突條按壓之密封材,在前述殼體主體之除了門支承部以外之前述開口部的周圍設置外密封材,在前述門沿著門支承部設置內密封材,在前述門關閉的狀態下,使前述突條與前述密封材密合,使除了前述門支承部以外之前述門的框緣與前述外密封材密合,使前述內密封材與前述殼體主體密合。

[發明所欲解決之問題][The problem to be solved by the invention]
然而,在密封材(襯墊),一般是採用橡膠等的材質,橡膠並無法百分之百防止聲音透過。因此,像專利文獻1那樣,將讓封裝件的回折部和主體之框抵接的構造和密封構件並用,可有效地降低噪音洩漏。However, the sealing material (liner) is generally made of rubber and other materials, and rubber cannot completely prevent sound from passing through. Therefore, as in Patent Document 1, the combination of a structure in which the folded-back portion of the package and the frame of the main body are in contact with the sealing member can effectively reduce noise leakage.
然而,近來,大尺寸的螺旋壓縮機之需求提高,伴隨此,封裝件也有大型化的傾向。縱使像這樣進行封裝件的大型化,因為針對從導管等的開口部漏出的聲音可採用種種的對策,從導管等漏出之噪音的降低變得比較容易。However, recently, the demand for large-sized screw compressors has increased, and with this, the package has also tended to increase in size. Even if the size of the package is increased in this way, various measures can be taken against the sound leaking from the opening of the duct, etc., and it becomes easier to reduce the noise leaking from the duct.
然而,另一方面,從門的間隙之聲音洩漏所造成之噪音,隨著封裝件的大型化,反而有增大的疑慮。與門尺寸變大成正比,門的變形量變大,形成於門和開口部間之間隙也變長。這樣的話,引發噪音洩漏之洩漏部的面積增大而使噪音洩漏變嚴重的可能性提高。However, on the other hand, the noise caused by the sound leakage from the gap of the door has become more suspicious as the size of the package becomes larger. In proportion to the increase in door size, the deformation of the door increases, and the gap formed between the door and the opening also increases. In this case, the area of the leakage portion that causes noise leakage increases, and the possibility that noise leakage becomes serious increases.
此外,雖有像專利文獻2之隔音封裝件那樣的使用複數個密封材的方法,但存在著成本、組裝耗費時間等的問題。In addition, although there is a method of using a plurality of sealing materials like the soundproof package of
本發明是有鑑於上述問題而開發完成的,其目的是為了提供一種隔音封裝件,不致讓製造成本、組裝工作增加,縱使大型化仍可確實地防止從間隙讓聲音往外部洩漏。 [解決問題之技術手段]The present invention was developed in view of the above problems, and its purpose is to provide a soundproof package that does not increase the manufacturing cost and assembly work, and can reliably prevent sound leakage from the gap to the outside even if it is enlarged.

依據本發明的隔音封裝件,不致讓製造成本、組裝工作增多,縱使大型化仍可確實地防止從間隙讓聲音往外部洩漏。According to the soundproof package of the present invention, the manufacturing cost and assembly work are not increased, and even if the size is increased, the sound leakage from the gap to the outside can be reliably prevented.
以下,針對本發明的隔音封裝件1之實施形態,參照圖式詳細地說明。Hereinafter, the embodiment of the soundproof package 1 of the present invention will be described in detail with reference to the drawings.
本發明的隔音封裝件1係具有:在內部收容噪音源且具備有開口部2之封裝件主體3、可將封裝件主體3的開口部2封閉之門4、及設置在封裝件主體3和門4之間且可將噪音源的噪音予以隔音之隔音構造5。該隔音封裝件1,是配置成將噪音源的周圍包圍而成為可將噪音源從外部隔絕之殼體,藉此防止從噪音源發出的噪音向外部洩漏。The soundproof package 1 of the present invention has: a package
具體而言,在隔音封裝件1設有開口部2,藉此可對在內部所收容之噪音源的設備等從外部實施維護及各種操作。而且,在開口部2設有可將該開口部2封閉的門4,在封裝件主體3和門4之間設置:可防止噪音源的噪音從開口部2的間隙向外部洩漏之隔音構造5。Specifically, an
本發明之設置隔音構造5的開口部2,是包含開口於殼體之壁面的一部分之小窗,也能在構成殼體之複數片壁面當中將1片壁面卸下,而將卸下壁面所形成的開口當作本發明的開口部2。在本實施形態,是舉將卸下壁面所形成的開口當作開口部2的例子,對本發明的隔音封裝件1詳細地說明。The
接下來說明,構成隔音封裝件1之封裝件主體3、該封裝件主體3的開口部2及可將開口部2封閉的門4。Next, a description will be given of the package
首先說明,在封裝件主體3所收容的噪音源。First, the noise source contained in the package
作為在封裝件主體3收容的噪音源,是具有在運轉中讓大噪音產生的機構之設備等。作為如此般讓噪音產生的設備,除了本實施形態所舉的螺旋壓縮機以外,還包括具有大的作動音的泵之設備等。As the noise source contained in the package
封裝件主體3,是設置成將上述噪音源包圍而將收容有噪音源之內部從外部隔絕,藉此抑制噪音向外部洩漏。具體而言,本實施形態的封裝件主體3係具備:可在上部載置噪音源之底座6、以將噪音源從周圍包圍的方式配置在底座6的外緣側之複數個框部7、配置在互相平行排列的框部7間且可將形成於框部7間之空隙(開口部2)封閉的門4、及配置在框部7及門4的上部之頂板8。The
亦即,封裝件主體3構成為,藉由將上述底座6、框部7、門4、頂板8等的構件配置在噪音源之上下左右前後,而將噪音封閉在殼體的內部。That is, the package
本實施形態的隔音封裝件1的情況,在門4和框部7之間設置鉸鏈9、固定部10,利用該等構件可將門4對於框部7以鉸鏈門的方式安裝。亦即,在本實施形態的隔音封裝件1,是使用框部7間的空隙作為開口部2,該開口部2是藉由門4而成為可開閉自如。In the case of the soundproof package 1 of this embodiment, a
以下說明,構成本實施形態的隔音封裝件1中之封裝件主體3的底座6、頂板8、柱及門4。The following describes the
如圖2所示般,底座6是上下方向的尺寸比水平方向(前後方向及左右方向)的尺寸小之角狀(板狀)構件,從上方觀察的情況是形成為左右方向較長的長方形般的形狀。又底座6亦可為大致正方形等的其他形狀。在底座6的中央載置圖示省略的噪音源。As shown in Fig. 2, the
此外,在上述底座6之外緣側的上表面,以沿著上下方向或水平方向的方式配置複數根框部7。複數根框部7,是以互相平行的方式在水平方向或上下方向隔著距離而配置。而且,複數根框部7當中,在互相平行排列的框部7之間設置門4。In addition, on the upper surface on the outer edge side of the
具體而言,上述框部7包含:以沿著上下方向的方式配置之縱框11、以沿著左右方向的方式配置之橫框12。Specifically, the
縱框11,是豎設在底座6的外緣側之長棒狀的構件,是一般被稱為「柱」的構件。縱框11之下端是利用螺栓等固定在底座6的外緣。此外,縱框11之上端是利用螺栓等固定在頂板8之外緣側的下表面。亦即,縱框11是以將底座6和頂板8之2點間在上下方向連結的狀態(將上下連結的狀態)進行安裝。The
橫框12,是將互相對向地配置之縱框11間在水平方向連結的構件,一般是使用L型角材等。橫框12包含:在上述縱框11的上端間沿水平方向架設者、在縱框11的下端間沿水平方向架設者。The
亦即,上述框部7,是將在水平方向隔著距離平行地配置且互相朝向上下方向之1組的縱框11、和在上下方向隔著距離平行地配置且互相朝向水平方向之1組的橫框12呈井狀地組合而構成。而且,在呈井狀地組合之框部7的中央形成開口部2。That is, the
換言之,本實施形態的隔音封裝件1之「開口部2」,是由互相呈井狀地組合之橫框12及縱框11所包圍的部分,形成於開口部2的周圍之「開口周圍面13」,就是互相呈井狀地組合之橫框12及縱框11的表面(面向外部的表面)。In other words, the "
例如,在圖1的例子,在正面側(圖之手邊側)是在左右方向等間隔地豎設5根縱框11,在背面側(圖之裡側)也是同樣地豎設5根縱框11。此外,該等縱框11當中,在左右方向、前後方向相鄰之縱框11之間,在上端側彼此間及下端側彼此間分別架設橫框12。亦即,在圖1的隔音封裝件1,是在10根縱框11間架設16根橫框12,全部共可形成8處的開口部2。For example, in the example of FIG. 1, five
又在圖2,在正面的(朝向前方開口)4個開口部2當中,舉最左側的開口部2為例,來說明開口部2和隔音構造5的關係。In FIG. 2, among the four
如圖2所示般,在上述開口部2之左側的縱框11,設置用於樞支後述的門4之鉸鏈9。該鉸鏈9,是在縱框11的上側和下側分別設置1個,而上下合計設置2個。此外,在上述開口部2的左側(在此的「左側」,是門4開放狀態之圖2上的左側)之縱框11,設置用於將門4固定於縱框11之固定部10。在圖2的例子,該固定部10是在與鉸鏈9大致相同的高度以相同的數量(上下合計2個)設置。As shown in FIG. 2, the
上述鉸鏈9,是對於封裝件主體3的框部7將門4樞支的構件。本實施形態的鉸鏈9係具有:安裝於縱框11側之第1構件9a、設置於門4側之第2構件9b。相對於第2構件9b使第1構件9a成為可繞朝向上下方向的軸轉動自如,藉此可對於封裝件主體3進行門4的樞支。The above-mentioned
此外,固定部10,藉由將設置在門4或封裝件主體3的一方之鉤部可卡脫自如地卡止於設置在門4或封裝件主體3的另一方之卡止部,可對於封裝件主體3進行門4的固定。In addition, the fixing
又上述鉸鏈9、固定部10的設置個數,相較於3個以上,以2個為佳。當鉸鏈9、固定部10設置了3個以上的情況,有受到公差的影響而使門4變得難以開閉的情況,還會有門4之變形變大而使其和框部7間的間隙變寬(聲音洩漏面積變大)的可能性。此外,如後述般會有在設有鉸鏈9的部位無法設置襯墊17的情況,因此鉸鏈9的設置個數越少越好。因此,考慮到隔音性提高的情況,鉸鏈9、固定部10的設置個數較佳為限定成2個。In addition, the number of the
頂板8是配置在框部7及門4的上側之構件,成為可將由框部7及門4所形成之殼體的上方開口封閉。頂板8是前後方向、左右方向的尺寸與底座6大致相同之板狀構件,以對於底座6在上方隔著距離且與底座6平行的方式沿著水平方向設置。The
門4是可將上述封裝件主體3的開口部2封閉之板狀構件,左右方向的尺寸、上下方向的尺寸形成為比開口部2稍大。換言之,上述門4的外緣側,安裝在閉門時可與封裝件主體3的框部7重疊的位置,成為與開口部2之開口周圍面13能以面狀態接觸。而且,在該門4的外緣側和封裝件主體3的開口周圍面13(框部7的表面)之間,設置本發明的特徵之隔音構造5。The
具體而言,如圖2所示般,上述門4,從正面觀察的情況,具有上下方向較長的長方形狀之門主體14(門4之主體部)。亦即,該門主體14,是由上邊、下邊比左邊、右邊短之縱長四角形的金屬板所形成。Specifically, as shown in FIG. 2, the above-mentioned
此外,在門主體14的外周側形成有回折片15,回折片15是使用朝與門主體14交叉的方向延伸之金屬板所形成。該回折片15,是在門主體14之上下左右分別設置,以門主體14之上下左右四邊為邊界而朝向封裝件主體3側以90°角度回折而設置。例如,以閉門狀態為基準,上側的回折片15,是從門主體14的上邊朝向後方(將門4關閉的情況,從防風封裝件1的外側朝向內側的方向;換言之,將門4關閉的情況,從門4之表面朝向背面的方向)沿水平方向延伸的構件,以上邊為邊界相對於門主體14以90°角度交叉地連結於門主體14。此外,右側的回折片15,是從門主體14的右邊朝向後方沿水平方向延伸之構件,以上邊為邊界相對於門主體14以90°角度交叉地連結於門主體14。In addition, a folding-
回折片15之封裝件主體3側的端部(與門主體14為相反側的端部),上下左右皆位於同一平面上,在用門4將開口部2封閉時,使各回折片15之回折端位於離開口周圍面13相同距離的位置。The end of the
本發明的隔音封裝件1之特徵在於,在封裝件主體3(框部7的表面或開口周圍面13)和門4之間設置可將噪音源的噪音予以隔音之隔音構造5。該隔音構造5,不是將吸音構件、襯墊(密封構件)單獨地使用來進行隔音,而是將吸音構件16和襯墊17雙方組合使用來進行隔音。The sound insulation package 1 of the present invention is characterized in that a
具體而言,在本發明的隔音封裝件1,開口周圍面13都位於同一平面上,包圍開口部2之縱框11及橫框12的表面都位於同一平面上。Specifically, in the soundproof package 1 of the present invention, the
而且,上述襯墊17,是安裝在回折片15之封裝件主體3側的端部,在藉由門4使開口部2成為封閉狀態時,襯墊17可與封裝件主體3之開口周圍面13(縱框11及橫框12的表面)接觸。此外,吸音構件16,是設置在比回折片15更靠門中央側,在藉由門4使開口部2成為封閉狀態時,是藉由與開口周圍面13接觸而使厚度變得比開放狀態時更薄。換言之,本發明的隔音封裝件1,是在縱框11及橫框12的表面讓襯墊17和吸音構件16雙方接觸,藉此使用吸音構件16和襯墊17雙方而進行隔音。Moreover, the
又關於設置上述襯墊17和吸音構件16,可考慮以下所示的實施形態。Regarding the provision of the
[第1實施形態]
如圖3所示般,第1實施形態的隔音封裝件1,是在門主體14的周緣(門4的外周緣)具有回折片15,回折片15是朝向封裝件主體3側回折而形成在與封裝件主體3的表面交叉的方向上。該回折片15,如上述般是設置在門4的上側、下側、左側及右側這4邊。而且,該回折片15之封裝件主體3側的端部(被回折的前端),4邊都位在同一平面上,在位於同一平面上的端部安裝上述襯墊17。[First Embodiment]
As shown in FIG. 3, the soundproof package 1 of the first embodiment has a
此外,設置在第1實施形態的隔音封裝件1之襯墊17,是設置在位於同一平面上之回折片15的端部,且設置在除設有鉸鏈9的部分以外之開口部2的全周。亦即,在本實施形態的隔音封裝件1,在設有鉸鏈9的部分,雖設有吸音構件16,但沒有設置襯墊17。In addition, the
具體而言,襯墊17是使用橡膠等之具備彈性的樹脂(構件)所形成。此外,襯墊17,是形成為內部中空的構造,當被朝向封裝件主體3側緊壓的情況可彈性變形。如果是如此般可彈性變形的襯墊17,縱使在回折片15的端部和開口周圍面13之間產生間隙的情況,因為彈性變形後的襯墊17可進入間隙而將間隙封閉,能防止從開口部2向外部讓噪音洩漏。Specifically, the
另一方面,設置在第1實施形態的隔音封裝件1之吸音構件16,是設置在比回折片15更靠門中央側的構件,在藉由門4使開口部2成為封閉狀態時,是藉由與開口周圍面13接觸而使厚度變得比開放狀態時更薄,如此可將開口周圍面13和門4的間隙封閉。On the other hand, the
具體而言,該吸音構件16,是發泡性的聚氨酯發泡材等之具備柔軟性、壓縮性的構件,安裝在比回折片15更靠門主體14的中央側(門中央側)。又在圖2中,雖將吸音構件16的圖示省略,如上述般,吸音構件16是設置在比回折片15更靠門中央側。此外,吸音構件16較佳為,具有比形成於開口部2的周圍之「開口周圍面13」稍大的形狀,而設置成大致覆蓋門4的背面。亦即,吸音構件16較佳為,將門主體14的中央側全面被覆。然而,如果未安裝吸音構件16的部分僅在門主體14之中央側的一部分,吸音性也可能下降不多。因此,本發明的隔音封裝件1也包含:吸音構件16未設置在門中央側的全面的情況,換言之在門中央側的一部分設置吸音構件16的情況。Specifically, the
此外,吸音構件16,宜在藉由門4使開口部2成為封閉狀態時,具有被夾在門4和開口部2之間而可將吸音構件16壓縮的厚度。具體而言,吸音構件16較佳為,形成為比門主體14到回折片15的端部之厚度、換言之門4之沿著前後方向的厚度更厚。如果以這樣的厚度來形成吸音構件16,吸音構件16之封裝件主體3側的端面變得比襯墊17之封裝件主體3側的端部更突出,在藉由門4使開口部2成為封閉狀態時,隨著襯墊17與開口周圍面13以面狀態接觸,吸音構件16也被壓縮,因此使用吸音構件16可將開口周圍面13和門4的間隙填滿,而能發揮穩定的隔音特性(吸音性)。In addition, when the
如上述第1實施形態所示般,如果將具備有襯墊17和吸音構件16雙方之隔音構造5設置在封裝件主體3和門4之間,襯墊17和吸音構件16可確實防止從開口部2的間隙讓噪音洩漏,因此可提供一種能將噪音源的噪音確實地隔音之隔音封裝件1。As shown in the above-mentioned first embodiment, if the
此外,第1實施形態的隔音封裝件1,是採用在門4之回折片15的前端設置襯墊17之簡單構造,因此不致造成製造成本、組裝工作增多。In addition, the soundproof package 1 of the first embodiment adopts a simple structure in which a
因此,不致造成製造成本、組裝工作增多,縱使大型化仍可確實地防止從間隙讓聲音向外部洩漏。Therefore, there is no increase in manufacturing cost and assembly work, and even if the size is increased, the sound leakage from the gap to the outside can be reliably prevented.
[第2實施形態]
第2實施形態的隔音封裝件1,與第1實施形態的隔音封裝件1同樣的,是在門主體14的周緣具有回折片15。[Second Embodiment]
The soundproof package 1 of the second embodiment is the same as the soundproof package 1 of the first embodiment in that it has a
第2實施形態的隔音封裝件1,與第1實施形態之不同點在於,設置在門主體14的周緣之回折片15,不是被朝向封裝件主體3側僅回折1次,而是將朝向封裝件主體3側回折1次後的前端(回折端)進一步朝向與開口周圍面13平行的方向回折(進行第2次的回折)。The soundproof package 1 of the second embodiment is different from the first embodiment in that the
亦即,設置在第2實施形態的隔音封裝件1之回折片15係具有第1回折片18和第2回折片19;第1回折片18,是在門主體14的周緣,被朝向封裝件主體3側回折而形成在與封裝件主體3的表面交叉的方向上;第2回折片19,是在第1回折片18的前端,被朝向寬度方向內側回折而形成在與開口周圍面13平行的方向上。而且,襯墊17是安裝於第2回折片19,吸音材形成為比從門主體14到第2回折片19的厚度更厚。That is, the
又上述第1及第2回折片18、19的設置場所,限定於未設置鉸鏈9的部位(圖2的C-C線剖面)。在設置鉸鏈9的部位(圖2的B-B線剖面),受到鉸鏈9的阻礙而無法安裝第2回折片19,也無法設置上述襯墊17。Moreover, the installation place of the said 1st and 2nd turn-
以下,針對設有鉸鏈9的部位和未設置鉸鏈9的部位,說明封裝件主體3及門4的剖面構造。Hereinafter, the cross-sectional structure of the
圖4A和圖4B係顯示圖2的B-B線剖面,是顯示在上述第2實施形態的隔音封裝件1中,設有鉸鏈9的部位之封裝件主體3及門4的剖面構造。又圖4A顯示門4開啟的狀態,圖4B顯示門4關閉的狀態。4A and 4B show a cross-section taken along the line B-B in FIG. 2, and show the cross-sectional structure of the package
如圖4A及圖4B所示般,封裝件主體3,是在開口部2的周圍具有上述框部7。框部7是中央成為開口部2之四角框狀的構件,並設置成包圍開口部2的周圍。框部7之遠離開口部2的側(外周側)設置在與門主體14的表面成為齊平的位置,框部7之接近開口部2的側則朝向封裝件主體3側凹陷。亦即,框部7,是在比門主體14的表面更裡側的位置具有開口周圍面13。而且,在該開口周圍面13設置上述鉸鏈9。As shown in FIG. 4A and FIG. 4B, the package
鉸鏈9係具有:安裝於開口周圍面13之第1構件9a、及安裝於門主體14之第2構件9b。鉸鏈9的第1構件9a和第2構件9b成為可繞朝向上下方向的軸轉動自如。The
門4具有第1回折片18,第1回折片18是在門主體14的周緣被朝向封裝件主體3側回折而形成在與封裝件主體3的表面交叉的方向上。該第1回折片18之封裝件主體3側的端部,是在到達開口周圍面13的途中終結,在此端部並未安裝襯墊17。The
此外,在比回折片15更靠門中央側的門主體14設置吸音構件16,吸音構件16在藉由門4使開口部2成為封閉狀態時是藉由與開口周圍面13接觸而使厚度變得比開放狀態時更薄。具體而言,開口周圍面13是延伸設置到比設有鉸鏈9的位置更靠門中央側,在該延伸設置的部分讓上述吸音構件16接觸。In addition, a
在設有上述鉸鏈9的部位,設置吸音構件16,但未設置襯墊17。相對於此,在未設置鉸鏈9的部位,設置吸音構件16和襯墊17雙方。At the location where the
圖5A和圖5B係顯示圖2的C-C線剖面,是顯示在上述第2實施形態的隔音封裝件1中,未設置鉸鏈9的部位之封裝件主體3及門4的剖面構造。又圖5A顯示門4開啟的狀態,圖5B顯示門4關閉的狀態。5A and 5B show a cross-section taken along the line C-C in FIG. 2 and show the cross-sectional structure of the package
如圖5A及圖5B所示般,未設置鉸鏈9的部位之封裝件主體3,與設有鉸鏈9的部位同樣的,在開口部2的周圍具有上述框部7,在開口部2的周圍,在比門主體14的表面更裡側的位置具有開口周圍面13。As shown in FIGS. 5A and 5B, the
另一方面,在門主體14的周緣,不僅被朝向封裝件主體3側回折而形成在與封裝件主體3的表面交叉的方向上之第1回折片18,還形成有在第1回折片18的前端被朝向寬度方向內側回折而形成在與開口周圍面13平行的方向上之第2回折片19,且在該第2回折片19安裝襯墊17。On the other hand, on the periphery of the
設置在第2實施形態的隔音封裝件1之襯墊17,是使用具有安裝部20及中空部21之橡膠襯墊等,安裝部20是以挾持狀態被安裝於第2回折片19,中空部21是為了易於變形而使內部成為中空。The
又上述第2回折片19,當第1回折片18的回折角度為90°的情況,不是從第1回折片18的下端進一步進行270°(亦即-90°)回折,而是從第1回折片18的下端進一步進行90°回折者(剖面ㄈ字狀(U-shaped type)回折者)。In addition, the above-mentioned second turn-
亦即,在未設置上述鉸鏈9的部位,設置吸音構件16和襯墊17,而配置具備襯墊17和吸音構件16雙方之隔音構造5。如果將這樣的隔音構造5設置在封裝件主體3和門4之間,襯墊17和吸音構件16可確實地防止從開口部2的間隙讓噪音洩漏,因此可提供能將噪音源的噪音確實地隔音之隔音封裝件1。That is, the sound-absorbing
特別是,當具備利用鉸鏈9進行開閉的門4的情況,在透過鉸鏈9進行開閉的門4和封裝件主體3之間,因為無論如何門4都會因本身重量而傾斜的關係,容易產生間隙。因此,當使用容易產生間隙之鉸鏈9的情況,第2實施形態的隔音封裝件1特別適用。In particular, when there is a
此外,第2實施形態的隔音封裝件1,是在形成在與開口周圍面13平行的方向上之第2回折片19設置襯墊17,而在互相以面狀態相對向之構件間配置襯墊17,因此可更有效地發揮利用襯墊17的遮音效果。In addition, in the soundproof package 1 of the second embodiment, a
再者,第2實施形態的隔音封裝件1也是與第1實施形態同樣的,是採用在門4之回折片15的前端設置襯墊17之簡單構造,因此不致讓製造成本、組裝工作增加。In addition, the soundproof package 1 of the second embodiment is the same as the first embodiment, and has a simple structure in which a
因此,不致讓製造成本、組裝工作增加,縱使大型化仍可確實地防止從間隙讓聲音向外部洩漏。Therefore, the manufacturing cost and assembly work are not increased, and even if the size is increased, the sound leakage from the gap to the outside can be reliably prevented.
