In this embodiment, referring to fig. 1 to 3, the self-elastic door lock in this embodiment includes a lock body portion 1 and a limit portion 2, which are respectively mounted on a door leaf and a door frame when in use, and are opposite when the door leaf is closed, and whether the door leaf is locked or not can be controlled by stretching and retracting a lock tongue 12 in the lock body portion 1.
Specifically, the lock body portion 1 includes a housing 11 and a latch 12 slidably disposed in the housing 11, an end plate 13 is disposed on one side of the housing 11, and a through hole for the latch 12 to extend and retract is disposed on the end plate 13. The bolt 12 can be extended and contracted by other linkage mechanisms in the shell 11, so as to realize unlocking and locking. However, how the lock tongue 12 moves is not a problem to be solved in the present application, so other structures inside the lock body portion 1 are not described herein. The end plates 13 extend to both ends of the housing 11 to form connection portions for mounting the lock body portion 1 on a door leaf or a door frame by means of screws or snaps or the like, and at least one connection portion is provided with the first magnet 3.
The limiting part 2 comprises in this embodiment a mounting plate 21, the middle part of which mounting plate 21 is formed with a latch hole 22 facing the through hole in the end plate 13, and the end part of the mounting plate 21 is provided with a second magnet 4. When the door lock is closed, the lock tongue 12 extends out of the shell 11 and enters the lock tongue hole 22, so that the lock body part 1 and the limiting part 2 can be limited, and further the lock is closed. In other embodiments, a latch slot opposite to the through hole on the end plate 13 may be formed in the middle of the mounting plate 21, so as to ensure that the latch 12 can be limited when the latch 12 extends. In addition, the main body of the limiting portion 2 adopts the mounting plate 21 in this embodiment, which is convenient to be mounted on the door leaf or the door frame in use, and needless to say, in other embodiments, the user can change the shape of the main body of the limiting portion 2 according to the actual situation of the door leaf and the door frame, so as to ensure that the technical problem to be solved by the present disclosure can be achieved when the main body of the limiting portion 2 has the second magnet 4, the latch hole 22 or the latch slot. For example, when the door leaf or the door frame is thin, the main body of the limiting portion 2 may be a groove structure that can be sleeved on the door leaf or the door frame.
When the door leaf is closed, the limit part 2 is opposite to the lock body part 1, and an interaction force (attractive force or repulsive force) is generated between the first magnet 3 and the second magnet 4, and by adjusting the positions of the two magnets and the rotation center of the lock body part 1 or the limit part 2, the lock body part 1 or the limit part 2 can be opened by a certain angle by utilizing the interaction force during unlocking. For example, the limiting part 2 is fixed on the door frame, and the lock body part 1 is fixed on the door leaf, so that the lock body part 1 can rotate along with the door leaf. In this case, when the door lock is closed, the acting force between the first magnet 3 and the second magnet 4 deviates from the rotation center of the lock body part 1, and after the lock tongue 12 is removed from the lock tongue hole 22 or the lock tongue groove, the acting force can drive the lock body part 1 to rotate, so that the door leaf is opened by a certain angle. In other words, the force is applied to the lock body portion 1, so that a moment for driving the door to open can be formed, and after the lock body portion 1 and the limit portion 2 lose the fit limit of the lock tongue 12 and the lock tongue hole 22, the moment can open the lock body portion 1 and the door leaf by a certain angle.
On the contrary, if the lock body part 1 is fixed on the door frame, the limiting part 2 is fixed on the door leaf, and the limiting part 2 can rotate along with the door leaf. By arranging the positions of the first magnet 3 and the second magnet 4, the limiting part 2 can be driven to rotate when the door lock is opened, and then the door leaf is opened at a certain angle. Therefore, when the self-ejection door lock is used, after a user opens the door lock, the door lock can be automatically opened at a certain angle, and the user can intuitively see that the door is unlocked.
In addition, lock body part 1 and spacing part 2 all can direct mount in the notch of reserving on door frame and door leaf in this from bullet formula door lock, need not to dig the notch of holding first magnet 3, second magnet 4 again on former door leaf and the door frame, have enlarged this from bullet formula door lock's application scope, and improved installation effectiveness.
Further, in this embodiment, the first magnet 3 is the same in height as the second magnet 4, but the second magnet 4 is provided on the stopper portion 2 at a position close to the outside of the lock body portion 1 (here, the inside and the outside refer to the door inside and the door outside when the door lock is in use), the first magnet 3 is closer to the door inside side than the second magnet 4, that is, the second magnet 4 is further up than the first magnet 3 in the drawing, while the like magnetic poles of the two are provided opposite to each other. In this state, in fig. 2, the rotation center of the lock body portion 1 is located at the right side of the center of the lock body portion, and a repulsive force is provided between the two magnets, and the direction of the repulsive force is located below the rotation center in fig. 2, so that after the lock tongue 12 is removed from the lock tongue hole 22, the repulsive force can drive the lock body portion 1 to rotate in the counterclockwise direction in fig. 2, and automatic door opening is achieved. For intelligent door locks, the user can clearly and intuitively know that the door has been opened. The first magnet 3 and the second magnet 4 have the same height, so that the distance between the first magnet and the second magnet can be shortened to the greatest extent while the door is opened, and the interaction force between the first magnet and the second magnet is improved.
Referring to fig. 4, in another embodiment, the first magnet 3 and the second magnet 4 have the same height, but the second magnet 4 is disposed on the limiting portion 2 near the inner side of the lock body portion 1, and the first magnet 3 is closer to the outer side of the door than the second magnet 4, i.e. the first magnet 3 is further up than the second magnet 4 in fig. 4, and opposite magnetic poles of the two magnets are disposed opposite to each other. In this state, in fig. 4, the rotation center of the lock body portion 1 is located at the right side of the center of the rotation center, and a attraction force is formed between the two magnets, and the direction of the attraction force is located above the rotation center in fig. 4, so that after the lock tongue 12 moves out of the lock tongue hole 22, the attraction force can drive the lock body portion 13 to rotate in the counterclockwise direction, and automatic door opening is achieved. For intelligent door locks, the user can clearly and intuitively know that the door has been opened.
In other embodiments, the end surfaces of the first magnet 3 and the second magnet 4 may be disposed opposite to each other (i.e., the heights of the two magnets in fig. 1, 2, and 4), and the rotational center of the lock body portion 1 or the limiting portion 2 may be shifted from the direction of the force between the two magnets. For example, when like poles of the two poles are opposite, the center of rotation is located outside of the force, i.e., on the upper side in fig. 2 and 4; as another example, when the opposite poles of the two poles are opposite, the center of rotation is located inboard of the force, i.e., the lower side in fig. 2 and 4. In both cases, the moment formed by the acting force between the magnets on the lock body part 1 or the limit part 2 can form a trend of driving the lock body part to rotate, and then after the lock tongue 12 is retracted, the door leaf is driven to open by a certain angle.
In addition, in one embodiment, the second magnet 4 may also be provided on the mounting plate 21 in a horizontally sliding manner. Therefore, when mounting, the user can adjust the position of the second magnet 4 in the horizontal direction according to the actual situation so as to achieve the best spring-open effect, and after the position adjustment is completed, the second magnet 4 can be fixed on the mounting plate 21 by the screws.
It should be noted that, in the above-mentioned situation, the moment formed by the interaction force between the two magnets on the lock body portion 1 or the limit portion 2 only needs to overcome the resistance when it rotates to spring the door leaf to a certain angle, and as the door leaf is opened, the magnitude of the interaction force and moment will change, so that the door leaf will not be continuously spring opened. The technical scheme in this disclosure aims at rotating lock body part 1 or spacing part 2 a certain angle, and then opens certain angle with the door leaf, and the user is informed that the door has been opened, consequently need not great magnetic force at the bullet door in-process, only set up two relative less magnet of volume and can realize this function, so this lock can not cause great influence to former door leaf and door frame when the installation.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
