Description
本發明與鎖具有關，尤指一種門鎖。The invention has a lock, in particular a door lock.
鎖具的種類有很多種，一般較為常見的是鑰匙鎖及號碼鎖，另外還有一種磁扣鎖是藉由磁鐵的磁力吸附滑動件，使滑動件固定於受口內來達到上鎖的效果，舉例來說，中華民國公開第201425708號專利案所揭露之磁扣鎖分別在滑動件與卡掣板設置至少一個磁力件，藉由兩個磁力件之間的互相吸引，滑動件即能伸入卡掣板之卡扣孔內，使門板得以保持在關門的狀態。There are many types of locks. Generally, the key lock and the combination lock are commonly used. In addition, a magnetic lock is a magnetic attraction slider of the magnet, so that the slide is fixed in the mouth to achieve the locking effect. For example, the magnetic lock disclosed in the Patent No. 201425708 of the Republic of China discloses at least one magnetic member on the sliding member and the clamping plate, respectively, and the sliding member can be inserted by mutual attraction between the two magnetic members. The inside of the snap hole of the gusset plate allows the door panel to remain closed.
就前述習用專利案來說，為了確保滑動件能夠保持在上鎖的狀態，藉由凸輪之帶動，使鎖制件相對帶動件偏轉而令卡制凸柱卡入定位槽內，同時鎖制件之一端會抵靠於殼體之內壁面的限止片，以限制滑動件的作動。然而在前述設計中，鎖制件與限止片之間的抵靠效果並不穩固，以至於鎖制件在撥動件受到過大的外力作用時可能被帶動件所拉動而逐漸脫離限止片，一旦鎖制件在完全脫離限止片之後，滑動件將會跟著被帶動件所拉動而形成開鎖狀態。由此可知，前述習用專利案在上鎖之後仍然有可能因為開門力道過大而產生失效的問題。In the case of the aforementioned conventional patent, in order to ensure that the sliding member can be kept in the locked state, the driving member is deflected by the cam to deflect the locking member into the positioning groove, and the locking member is locked. One end will abut against a limiting piece on the inner wall surface of the housing to limit the actuation of the slider. However, in the foregoing design, the abutting effect between the locking member and the limiting piece is not stabilized, so that the locking member may be pulled by the driving member and gradually disengage from the limiting piece when the dialing member is subjected to an excessive external force. After the lock member is completely detached from the limit piece, the slide member will be pulled by the driven member to form an unlocked state. It can be seen from the above that after the above-mentioned conventional patent case is still likely to be ineffective due to the excessive opening force of the door.

The cam 51 is mounted in the middle hole 23 of the housing 20 and has a first convex portion 512. The locking member 52 has a stopping portion 521, a pivoting portion 522, and a stopping groove adjacent to the stopping portion 521. 523, and a second protrusion 524 between the blocking portion 521 and the pivoting portion 522, wherein, as shown in Figures 2 to 4, the pivoting portion 522 of the locking member 52 has a pivot hole 525 and The pivot hole 525 is sleeved on the pivot portion 413 of the transmission member 41, and the aperture of the pivot hole 525 is larger than the outer diameter of the pivot portion 413, so that the lock member 52 can pivot relative to the transmission member 41, and at the same time The second transmitting portion 524 of the locking member 52 abuts against the first convex portion 512 of the cam 51 so that the locking member 52 can be pushed by the cam 51, and further, the locking member 52 faces the transmission member. One side of the 41 has a second positioning portion 526, and the second positioning portion 526 is embedded in the longitudinal limiting groove 415 of the transmission member 41 (as shown in Figures 2, 7 and 8), and the top surface of the locking member 52 There is a spring groove 527; the fourth elastic member 53 is exemplified by a compression spring. The fourth elastic member 53 is received in the spring groove 527 of the lock member 52 and abuts against the transverse direction of the transmission member 41 at both ends thereof. Stretching wall 416 The end wall of the spring groove 527 of the lock member 52 is used to apply the pushing force to the lock member 52.
當門板處於開啟狀態時，滑動件31會受到第一彈性件37之拉力作用而保持在殼體20內，如第3圖所示，所以在關門的過程中不會與受口板12之間產生撞擊的情況，待完全關閉門板之後，藉由受口板12之磁力件14的吸引，滑動件31之鎖舌部32會伸出殼體20外且嵌卡於受口板12之受口16內，如第4圖所示，如此藉由滑動件31之鎖舌部32與受口板12之受口16之間的互相卡制，使門板保持在關門的狀態。When the door panel is in the open state, the slider 31 is held in the housing 20 by the pulling force of the first elastic member 37, as shown in FIG. 3, so that it does not overlap with the mouthpiece 12 during the door closing process. In the case of an impact, after the door panel is completely closed, the latching portion 32 of the slider 31 protrudes out of the housing 20 and is engaged with the mouth of the mouthpiece 12 by the attraction of the magnetic member 14 of the mouthpiece 12. In the case of Fig. 4, as shown in Fig. 4, the door panel is held in a closed state by mutual engagement between the tongue portion 32 of the slider 31 and the mouthpiece 16 of the mouthpiece 12.
當要開門時，如第5圖所示，先轉動與撥動件43連接之一門把(圖中未示)，使撥動件43隨之轉動，接著撥動件43之推抵部432會推動傳動件41之第一受抵部411，使傳動件41朝遠離滑動件31的方向移動，在傳動件41移動的過程中，傳動件41會藉由第二卡接部412與滑動件31之第一卡接部35之間的卡接關係帶動滑動件31內縮至殼體20內，如第5圖所示，如此即可將門板開啟。When the door is to be opened, as shown in FIG. 5, a door handle (not shown) connected to the dial member 43 is first rotated to rotate the dial member 43, and then the pushing portion 432 of the dial member 43 is rotated. The first abutting portion 411 of the transmission member 41 is pushed to move the transmission member 41 away from the sliding member 31. During the movement of the transmission member 41, the transmission member 41 passes the second engaging portion 412 and the sliding member 31. The latching relationship between the first latching portions 35 causes the slider 31 to be retracted into the housing 20, as shown in Fig. 5, so that the door panel can be opened.
另一方面，當門板在關閉狀態下要對凸輪51上鎖時，如第6圖所示，首先使用一鑰匙(圖中未示)將凸輪51自一第一開鎖位置P1轉動至一上鎖位置P3，在凸輪51轉動的過程中，凸輪51之第一凸部512會往上推動鎖制件52之第二凸部524，使鎖制件52相對傳動件41往上偏轉且同時擠壓第四彈性件53，在同一時間內，鎖制件52之第二定位部526會沿著傳動件41之縱向限位槽415往上位移，一旦凸輪51轉動至上鎖位置P3時，如第7圖所示，鎖制件52之第二定位部526會跨過殼體20之第一定位部24的定位凸部244且藉由第四彈性件53的回復力量卡接於殼體20之第一定位部24的定位缺口242內，這時候鎖制件52之擋止部521會抵靠於滑動件31之第一卡接部35，如第6圖所示，用以對滑動件31提供鎖制效果，使滑動件31無法縮回至殼體20內。此外，在凸輪51推動鎖制件52的過程中會同步帶動傳動件41往滑動件31的方向移動，當凸輪51位於上鎖位置P3時，傳動件41之第一受抵部411會遠離於撥動件43之推抵部432，使撥動件43在受力轉動時無法藉由推抵部432推動傳動件41之受抵部411。On the other hand, when the door panel is to be locked in the closed state, as shown in Fig. 6, first, a key (not shown) is used to rotate the cam 51 from a first unlock position P1 to a lock. At position P3, during the rotation of the cam 51, the first convex portion 512 of the cam 51 pushes up the second convex portion 524 of the lock member 52, causing the lock member 52 to be deflected upward relative to the transmission member 41 and simultaneously pressed. The fourth elastic member 53 is at the same time, the second positioning portion 526 of the locking member 52 is displaced upward along the longitudinal limiting groove 415 of the transmission member 41, and once the cam 51 is rotated to the locking position P3, as in the seventh As shown, the second positioning portion 526 of the locking member 52 straddles the positioning protrusion 244 of the first positioning portion 24 of the housing 20 and is engaged with the housing 20 by the restoring force of the fourth elastic member 53. In the positioning notch 242 of the positioning portion 24, the blocking portion 521 of the locking member 52 will abut against the first engaging portion 35 of the sliding member 31, as shown in FIG. 6, for providing the sliding member 31. The locking effect prevents the slider 31 from retracting into the housing 20. In addition, during the process of the cam 51 pushing the locking member 52, the driving member 41 is synchronously moved in the direction of the sliding member 31. When the cam 51 is in the locking position P3, the first abutting portion 411 of the transmission member 41 is away from The pushing portion 432 of the dialing member 43 prevents the pushing member 43 from pushing the receiving portion 411 of the transmission member 41 by the pushing portion 432 when the biasing member 43 is rotated.
當要對凸輪51開鎖時，同樣使用鑰匙將凸輪51自上鎖位置P3轉動至第一開鎖位置P1，如第4圖所示，在凸輪51轉動的過程中，凸輪51之第一凸部512會往上推動鎖制件52之第二凸部524，使鎖制件52之第二定位部526沿著傳動件41之縱向限位槽415往上位移且逐漸脫離殼體20之第一定位部24的定位缺口242，一旦凸輪51轉動至第一開鎖位置P1時，如第8圖所示，鎖制件52之第二定位部526會脫離殼體20之第一定位部24的定位缺口242且抵靠於定位凸部244背對定位缺口242之一端，這時候鎖制件52之擋止部521會遠離於滑動件31之第一卡接部35，如第4圖所示，用以解除對滑動件31的鎖制效果。此外，在凸輪51推動鎖制件52的過程中會同步帶動傳動件41往遠離滑動件31的方向移動，當凸輪51位於開鎖位置P2時，傳動件41之第一受抵部411會剛好對應於撥動件43之推抵部432，使撥動件43在受力轉動時能夠藉由推抵部432推動傳動件41之第一受抵部411。When the cam 51 is to be unlocked, the cam 51 is also rotated from the locking position P3 to the first unlocking position P1 using a key. As shown in Fig. 4, during the rotation of the cam 51, the first convex portion 512 of the cam 51 is rotated. The second protrusion 524 of the lock member 52 is pushed upward, so that the second positioning portion 526 of the lock member 52 is displaced upward along the longitudinal limiting groove 415 of the transmission member 41 and gradually disengages from the first positioning of the housing 20. The positioning notch 242 of the portion 24, when the cam 51 is rotated to the first unlocking position P1, as shown in FIG. 8, the second positioning portion 526 of the locking member 52 is disengaged from the positioning notch of the first positioning portion 24 of the housing 20. 242, and the positioning protrusion 244 is opposite to the one end of the positioning notch 242. At this time, the blocking portion 521 of the locking member 52 is away from the first engaging portion 35 of the sliding member 31, as shown in FIG. In order to release the locking effect on the slider 31. In addition, during the process of the cam 51 pushing the lock member 52, the transmission member 41 is synchronously moved in the direction away from the slider 31. When the cam 51 is located at the unlocking position P2, the first abutting portion 411 of the transmission member 41 will correspond exactly. In the pushing portion 432 of the dialing member 43, the first abutting portion 411 of the transmission member 41 can be pushed by the pushing portion 432 when the dialing member 43 is rotated by force.
另一方面，請參閱第9圖，在本發明第2實施例中省略了撥動件43與第三彈性件44的設置，這時候如果要開門時需要將凸輪51由第一開鎖位置P1轉動至一第二開鎖位置P2，使凸輪51之第一凸部512推動傳動件41之第二受抵部417，使傳動件41朝遠離滑動件31的方向移動，在傳動件41移動的過程中，傳動件41會藉由第二卡接部412與滑動件31之第一卡接部35之間的卡接關係帶動滑動件31內縮至殼體20內，如此即可在簡化結構的狀況下達到開啟門板的效果。On the other hand, referring to Fig. 9, in the second embodiment of the present invention, the arrangement of the dial member 43 and the third elastic member 44 is omitted. At this time, if the door is to be opened, the cam 51 needs to be rotated by the first unlocking position P1. Up to a second unlocking position P2, the first convex portion 512 of the cam 51 pushes the second abutting portion 417 of the transmission member 41 to move the transmission member 41 away from the sliding member 31, during the movement of the transmission member 41. The transmission member 41 causes the sliding member 31 to be retracted into the casing 20 by the engaging relationship between the second engaging portion 412 and the first engaging portion 35 of the sliding member 31, so that the structure can be simplified. The effect of opening the door panel is reached.
綜上所陳，本發明之門鎖10能夠藉由凸輪51與鎖制件52的搭配對滑動件31提供穩固的鎖制效果，以確保在上鎖之後不會被意外開啟，而且，請再參閱第3圖，當滑動件31被第一彈性件37所拉動而縮回至殼體20內時，滑動件31之第一卡接部35與鎖制件52之擋止槽523之間會形成相互卡制，此時使用鑰匙也無法將凸輪51自第一開鎖位置P1轉動至上鎖位置P3，換言之，當門板處於開啟狀態下無法對凸輪51進行上鎖動作。In summary, the door lock 10 of the present invention can provide a stable locking effect on the sliding member 31 by the combination of the cam 51 and the locking member 52, so as to ensure that it will not be accidentally opened after being locked, and, please Referring to FIG. 3, when the slider 31 is retracted into the housing 20 by the first elastic member 37, the first engaging portion 35 of the slider 31 and the stopper groove 523 of the lock member 52 are The mutual locking is formed, and at this time, the cam 51 cannot be rotated from the first unlocking position P1 to the locking position P3 by using the key, in other words, the cam 51 cannot be locked when the door panel is in the open state.
