Description
本發明係關於一種多點緊固式鎖系統及使用該鎖系統的防爆門，其是使用於會由於防爆門等框體內部之壓力的上升而接觸到較大之壓力的門且被要求能確實地固定於框體的門。 The present invention relates to a multi-point fastening lock system and an explosion-proof door using the lock system. It is used for a door that is exposed to a large pressure due to an increase in pressure inside a frame such as an explosion-proof door, and is required to be able to The door of the frame is fixed firmly.
一般的高壓配電箱等，在框體內部將高電壓切斷(短路)時，其電能會瞬間集中且釋放出電弧(arc)，而該被釋放出的電弧會成為如***的狀態，框體內變成高壓，有時門會被吹走。此種框體的門，係為了防備如此短路電弧發生時的內壓上升，而採用防爆結構。防爆門係強化鉸鏈(hinge)或鎖定部等，並下了工夫以免門因內部***而破損，影響到周邊的機器或周邊的人們。 In general high-voltage distribution boxes, etc., when the high voltage is cut (short-circuited) inside the frame, the electrical energy will be instantly concentrated and an arc will be released, and the released arc will be in an explosive state. It becomes high voltage and sometimes the door is blown away. The door of this frame adopts an explosion-proof structure in order to prevent the internal pressure from rising when such a short-circuit arc occurs. Explosion-proof doors are reinforced with hinges or locks, etc., and work has been done to prevent the doors from being damaged due to an internal explosion, affecting the surrounding equipment or people.
此種的防爆門，例如已記載於JP-3034496-U等。該文獻的防爆門，係透過鉸鏈構件而連結於框體的一側部，且在另一側部配設有卡止金屬配件等的鎖裝置，藉由此等鉸鏈構件和鎖裝置，使門密接地緊固於框體，以免因短路電弧發生時的暴風，使框體內部的破損物飛散至框 體外部。 Such an explosion-proof door is described in, for example, JP-3034496-U.

然後，在該多點緊固式鎖系統S中，係如 第6圖所示，將門本體d之轉動側的側部在複數個部位藉由鎖定構件2與承接部5之卡合來固定，尤其是各部位的鎖定構件2和承接部5是由剛體所構成，且如第14圖(b)所示，成為使鉤部222之鎖定卡合面R1與鉤卡合部52之鎖定被卡合面R2在與鉤板22之作動支點部225大致相同的高度位置對接卡合之卡合形式，所以此成為足以抵抗朝向將門本體d從框體B之內部推出至外部的方向之力的耐壓結構，例如即便是在因框體B內部發生短路電弧等而使框體內部的壓力上升，並對門本體d施加有數噸之壓力的情況下，仍能堅固地維持各鎖止點的鎖定構件2與承接部5之卡合狀態，且能確實地將門本體d固定住。 Then, in the multi-point tight lock system S, it is As shown in FIG. 6, the side portion of the rotation side of the door body d is fixed at a plurality of positions by the engagement of the locking member 2 and the receiving portion 5, and in particular, the locking member 2 and the receiving portion 5 of each part are made of a rigid body. The structure is such that, as shown in FIG. 14 (b), the locking engagement surface R1 of the hook portion 222 and the locking engagement surface R2 of the hook engagement portion 52 are substantially the same as the operating fulcrum portion 225 of the hook plate 22. The high-position butt-engaging engagement form makes it a pressure-resistant structure that is strong enough to withstand the force that pushes the door body d from the inside of the frame B to the outside. For example, even if a short-circuit arc occurs inside the frame B, etc. When the pressure inside the frame is increased and the door body d is applied with a pressure of several tons, the engagement state of the lock member 2 and the receiving portion 5 at each lock point can be maintained firmly, and the door body can be reliably held. d is fixed.
如以上說明，依據該多點緊固式鎖系統S，由於是在門本體d的轉動側之側部的複數個部位設置由剛體所構成的鎖定構件2，與之對應而在框體B側設置由剛體所構成的承接部5，藉由手柄4之操作來驅動鎖定桿3，以使各鎖定構件2之鉤板22的作動支點部225將鉤板22之轉動支點部221作為轉動中心而轉動，藉此將鉤板22之鉤部222***框體B側的各承接部5之鉤卡合部52內，且使鉤部222之鎖定卡合面R1與鉤卡合部52之鎖定被卡合面R2在與鉤板22之作動支點部225大致相同的高度位置對接卡合，所以可以將門本體d之轉動側的側部在複數個部位藉由鎖定構件2與承接部5之卡合而固定，尤其是可以藉由各部位的鎖定構件2與承接部5之較高的剛性及其卡合形式，來實現足以抵抗朝向將門本體d從框體B之 內部推出至外部的方向之力的耐壓結構，例如即便是在因框體B內部發生短路電弧等而使框體B內部的壓力上升，並對門本體d施加有數噸之壓力的情況下，仍可以維持各鎖止點的各構件2、5之卡合，且確實地將門本體d固定住。 As described above, according to this multi-point fastening lock system S, since the locking member 2 made of a rigid body is provided at a plurality of positions on the side of the rotation side of the door body d, it corresponds to the side of the frame B A receiving portion 5 composed of a rigid body is provided, and the lock lever 3 is driven by the operation of the handle 4 so that the operating fulcrum portion 225 of the hook plate 22 of each locking member 2 uses the rotation fulcrum portion 221 of the hook plate 22 as the rotation center. By turning, the hook portion 222 of the hook plate 22 is inserted into the hook engagement portion 52 of each receiving portion 5 on the side of the frame B, and the lock engagement surface R1 of the hook portion 222 and the lock engagement portion 52 are locked. The engaging surface R2 is engaged with and engaged at substantially the same height position as the operating fulcrum portion 225 of the hook plate 22, so that the side portion on the rotation side of the door body d can be engaged with the receiving portion 5 by the locking member 2 at a plurality of locations. For fixing, the high rigidity of the locking member 2 and the receiving part 5 and the engaging form of the locking member 2 in each part can be used to achieve sufficient resistance to the door body d from the frame body B. A pressure-resistant structure with a force pushing out from the inside to the outside, for example, even if the pressure inside the frame B rises due to a short circuit arc or the like inside the frame B, and a pressure of several tons is applied to the door body d, It is possible to maintain the engagement of the members 2 and 5 at each lock point and securely fix the door body d.
從而，依據該防爆門D，則藉由使用多點緊固式鎖系統S，就可以將門本體d之轉動側的側部在複數個部位藉由鎖定構件2與承接部5之卡合而固定，尤其是可以藉由各部位的鎖定構件2與承接部5之較高的剛性及其卡合形式，來實現足以抵抗朝向將門本體d從框體B之內部推出至外部的方向之力的耐壓結構，例如即便是在因框體B內部發生短路電弧等而使框體B內部的壓力上升，並對門本體d施加有數噸之壓力的情況下，仍可以維持各鎖止點的各構件2、5之卡合，且確實地將門本體d固定住。 Therefore, according to the explosion-proof door D, by using the multi-point fastening lock system S, the side portion of the rotation side of the door body d can be fixed at a plurality of positions by the engagement of the locking member 2 and the receiving portion 5 In particular, the high rigidity of the locking member 2 and the receiving portion 5 in each part and the engagement form thereof can be used to achieve resistance enough to resist the force in the direction of pushing the door body d from the inside of the frame B to the outside. Pressure structure, for example, even if the internal pressure of the frame B rises due to a short circuit arc or the like inside the frame B, and the door body d is applied with a pressure of several tons, each member 2 of each lock point can be maintained. And 5 are engaged, and the door body d is surely fixed.
又，在該多點緊固式鎖系統S及使用該鎖系統S的防爆門D中，由於是使用下部側鎖定構件D2、上部側鎖定構件U2、下部側之鎖定桿D3、上部側之鎖定桿U3、以及下部側、上部側之各鎖定構件D2、U2共通的手柄4，且使手柄4的下部側之作動桿46、上部側之作動桿47分別作動連結於下部側之鎖定桿D3、上部側之鎖定桿U3，並藉由使手柄桿42倒伏於手柄底座41上的手柄桿42之轉動操作，將下部側、上部側之各作動桿46、47打開成大致八字形，並分別將下部側之作動桿46朝向下方向驅動，將上部側之作動桿47朝向上方向驅動，將下部側之鎖定構件D2的鉤板22朝向下方向轉動以使鉤部222從上 方卡合於承接部5之鉤卡合部52，將上部側之鎖定構件U2的鉤板22朝向上方向轉動以使鉤部222從下方卡合於承接部5之鉤卡合部52，且相反地，藉由使手柄桿42立起於手柄底座41上的手柄桿42之轉動操作，將下部側、上部側之各作動桿46、47閉合成大致倒八字形，並分別將下部側之作動桿46朝向上方向驅動，將上部側之作動桿47朝向下方向驅動，將下部側之鎖定構件D2的鉤板22朝向上方向轉動以使鉤部222從承接部5之鉤卡合部52脫離，將上部側之鎖定構件U2的鉤板22朝向下方向轉動以使鉤部222從承接部5之鉤卡合部52脫離，所以可以將多點緊固式鎖系統S組入縱長的防爆門D之較長的側部全區域，且在易於進行手柄操作的門本體d之上下方向中間位置設置手柄4，即便是縱長的防爆門D，仍可以確實地將門本體d固定住，且亦容易進行手柄操作。 In the multi-point tight lock system S and the explosion-proof door D using the lock system S, the lower-side lock member D2, the upper-side lock member U2, the lower-side lock lever D3, and the upper-side lock are used. The lever U3 and the lower and upper locking members D2 and U2 share the handle 4 in common, and the lower lever 46 and the upper lever 47 are respectively connected to the lower lever D3, The upper locking lever U3, and by turning the handle lever 42 on the handle base 41 to turn the handle lever 42 on, open each of the lower lever and upper lever 46, 47 into a substantially figure-eight, and respectively The lower operating lever 46 is driven downward, the upper operating lever 47 is driven upward, and the hook plate 22 of the lower locking member D2 is rotated downward so that the hook portion 222 is from above. The square is engaged with the hook engaging portion 52 of the receiving portion 5, and the hook plate 22 of the upper-side locking member U2 is turned upward so that the hook portion 222 is engaged with the hook engaging portion 52 of the receiving portion 5 from below. Conversely, by turning the handle lever 42 to stand the handle lever 42 on the handle base 41, the operating levers 46 and 47 on the lower side and the upper side are closed into a substantially inverted sigma shape, and the lower side The actuating lever 46 is driven in an upward direction, and the actuating lever 47 in the upper side is driven in a downward direction, and the hook plate 22 of the lower-side locking member D2 is turned upward, so that the hook portion 222 is moved from the hook engaging portion 52 of the receiving portion 5 For disengagement, turn the hook plate 22 of the upper locking member U2 downward so that the hook portion 222 is disengaged from the hook engaging portion 52 of the receiving portion 5. Therefore, the multi-point tightening lock system S can be assembled into a lengthwise The entire side of the longer side of the explosion-proof door D is provided with a handle 4 at the middle position above and below the door body d, which is easy to handle. Even the longitudinal explosion-proof door D, the door body d can be reliably fixed. It is also easy to handle.
又，由於在該手柄4，並具備用以限制已倒伏收納於手柄底座41上的手柄桿42之轉動並將手柄桿42固持於手柄底座41上之由鉤61和鉤承接部62所構成的桿掣子6，所以可以藉由使手柄桿42倒伏於手柄基體41上的簡單操作，使桿掣子6的鉤61與鉤承接部62彈性卡合，以將手柄桿42確實地固持於手柄底座41上，且確實地維持各鎖定構件2對各承接部5的卡合狀態，並更確實地保持門本體d的緊固狀態。 In addition, the handle 4 is provided with a hook 61 and a hook receiving portion 62 for restricting the rotation of the handle lever 42 stored on the handle base 41 and holding the handle lever 42 on the handle base 41. The lever pawl 6 allows the hook 61 of the lever pawl 6 and the hook receiving portion 62 to be elastically engaged by a simple operation of putting the lever 42 on the handle base 41 to securely hold the lever 42 to the handle. On the base 41, the engagement state of each of the lock members 2 to each of the receiving portions 5 is reliably maintained, and the fastening state of the door body d is more surely maintained.
而且，由於藉由該桿掣子6而致使的手柄桿42之轉動限制係藉由使用圓筒鎖71的鎖組件7來解除， 所以當手柄桿42暫時收納於手柄底座41上時就會變成鎖定狀態，且該鎖定解除係僅有圓筒鎖71之鍵的管理者所能進行，從而對於限制防爆門等安全管理上不特定多數之人員的開閉，且在常態需要上鎖的門極為有效。 Moreover, the rotation restriction of the handle lever 42 caused by the lever detent 6 is released by using the lock assembly 7 of the cylinder lock 71, Therefore, when the handle lever 42 is temporarily stored on the handle base 41, it will be locked, and the lock release can only be performed by the administrator of the key of the cylinder lock 71, so it is not specific for safety management such as limiting explosion-proof doors. Most people open and close doors that are normally locked, which is extremely effective.
另外，在該實施形態中，雖然承接部係具備固定部及鉤卡合部，且該固定部係固定於框體，該鉤卡合部係從固定部之一端延伸成俯視觀察呈剖面大致L字形形狀，且將該大致L字形形狀當中與固定部平行(安裝時)且朝向框體(之正面)側的面作為鎖定被卡合面並形成為大致直線的平坦面，但是該承接部之鉤卡合部，亦可從固定部之一端延伸成俯視觀察呈剖面大致U字形形狀，且將該大致U字形形狀當中與固定部平行(安裝時)且朝向框體(之正面)側的面作為鎖定被卡合面並形成為大致直線的平坦面。即便如此對承接部而言仍可以獲得與上述實施形態同樣的作用功效。 Further, in this embodiment, although the receiving portion includes a fixing portion and a hook engaging portion, and the fixing portion is fixed to the frame, the hook engaging portion extends from one end of the fixing portion to a substantially L-shaped cross section in plan view. Shape, and a surface that is parallel to the fixed portion (at the time of mounting) and faces the frame (front side) of the substantially L-shaped shape is a flat surface that locks the engaged surface and is substantially straight. The hook engaging portion may also be extended from one end of the fixing portion into a generally U-shaped cross section in plan view, and a surface of the substantially U-shape parallel to the fixing portion (when mounted) and facing the frame (front) side. It forms a substantially straight flat surface as a locked engagement surface. Even in this way, the receiving portion can obtain the same function and effect as those of the above embodiment.
又，複數個鎖定構件係具備下部側鎖定構件以及上部側鎖定構件，該下部側鎖定構件配置於門本體之複數個安裝部位當中的下部側之安裝部位該上部側鎖定構件配置於上部側之安裝部位，且下部側鎖定構件係使鉤板之鉤部的前端朝下安裝於下部側之安裝部位，下部側鎖定構件之鉤板的作動支點部係軸支於下部側之鎖定桿，上部側鎖定構件係使鉤板之鉤部的前端朝上安裝於上部側之安裝部位，上部側鎖定構件之鉤板的作動支點部係軸支於上部側之鎖定桿，在門之正面且相當於下部側鎖定構件與 上部側鎖定構件之間的位置安裝有下部側鎖定構件及上部側鎖定構件共通的手柄，並使手柄與下部側及上部側之各鎖定桿作動連結，但是複數個鎖定構件亦可不特別作為下部側鎖定構件、上部側鎖定構件，而是全部使鉤板之鉤部的前端朝向下方或朝上安裝於各安裝部位，並使各鎖定構件之鉤板的作動支點部軸支於共通的鎖定桿，且在門之正面且相當於鎖定桿之一方端的位置安裝有一般週知的既有之多點緊固用之手柄，並使手柄與鎖定桿作動連結。即便是如此對於門本體之固定而言仍能達成與上述實施形態同樣的作用功效。 In addition, the plurality of lock members are provided with a lower lock member and an upper lock member, and the lower lock member is disposed at a lower mounting portion of the plurality of mounting portions of the door body, and the upper lock member is disposed at an upper side. And the lower side locking member is mounted on the lower side with the front end of the hook portion of the hook plate facing downward, and the operating fulcrum portion of the hook plate of the lower side locking member is pivotally supported by the lower side locking lever, and the upper side is locked The component is mounted on the upper side with the front end of the hook portion of the hook plate facing upward, and the operating fulcrum portion of the hook plate of the upper locking member is pivotally supported by the upper side locking lever, which is on the front side of the door and corresponds to the lower side. Lock member with A handle common to the lower lock member and the upper lock member is installed at a position between the upper lock members, and the handle is operatively connected to each of the lower and upper lock levers, but a plurality of lock members may not be particularly used as the lower side. The locking member and the upper-side locking member are all mounted on each mounting portion with the front end of the hook portion of the hook plate facing downward or upward, and the operating fulcrum portion of the hook plate of each locking member is pivotally supported by a common lock lever.
