Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lock bodies, and particularly relates to a magnetic attraction lock body. Background Art
[0002] A magnetic attraction lock body is a lock body that drives a lock tongue to rotate and insert into a buckle box installed on a door frame through the magnetic attraction force generated between the lock tongue and the buckle box. This magnetic attraction lock body realizes unlocking by driving an unlocking dial by a handle to drive the lock tongue to rotate and retract into the lock shell. In addition, an anti-lock structure is usually installed in the lock shell of the magnetic attraction lock body. The anti-lock structure generally includes an anti-lock piece and an anti-lock dial driven by a key or a knob, etc. A torsion spring is arranged between the anti-lock piece and the lock shell. When the lock tongue rotates and extends out of the lock shell to insert into the buckle box, the user can operate the anti-lock dial to drive the anti-lock piece to rotate to an anti-lock position where it abuts against the lock tongue, and then the lock body can keep the anti-lock piece in the anti-lock position through the torsion spring, so as to restrict the lock tongue from rotating and retracting into the lock shell. However, for the existing magnetic attraction lock body, when it is in the anti-lock state, it cannot well prevent the lock tongue from being unlocked by external force. If the external force received by the lock tongue can overcome the suction force of the buckle box and the torsion force of the torsion spring that drives the anti-lock piece to stay in the anti-lock position, the lock tongue will be able to push open the anti-lock piece and then retract into the lock shell, resulting in accidental unlocking, and the safety needs to be further improved.

DETAILED DESCRIPTION
[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0024] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0026] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0027] Compared with the traditional mechanical lock body, the structure of the magnetic lock body is simpler. However, although the existing magnetic lock body is provided with an anti-locking structure, the existing anti-locking structure is not perfect. If the external force on the lock tongue 200 can overcome the suction force of the buckle box and the torque of the torsion spring 710 driving the anti-locking plate 300 to remain in the anti-locking position, the lock tongue 200 can push the anti-locking plate 300 away and retract the lock shell 100 to unlock. For this reason, in order to prevent people from subjecting the lock tongue 200 to external force by using the handle in the anti-locking state, the existing magnetic lock body is provided with an unlocking part that cooperates with the unlocking peg 600 on the anti-locking plate 300. When the magnetic lock body is in the anti-locking state, the unlocking peg 600 cannot touch the unlocking part. When the magnetic lock body is in the unlocking state, the unlocking peg 600 can touch the unlocking part, so that the unlocking peg 600 can be rotated by the handle, and then the unlocking part is pushed to drive the anti-locking plate 300 to drive the lock tongue 200 to retract the lock shell 100, thereby unlocking. In addition, since the lock tongue 200 of the magnetic lock body is magnetic or is equipped with a magnet 230, it is very likely that someone outside the door will use the magnet 230 to apply external force to the lock tongue 200 to drive the lock tongue 200 to retract into the lock shell 100 for unlocking, but the existing magnetic lock body is difficult to prevent this situation.
[0028] Reference Figure 1 According to an embodiment of the utility model, a magnetic lock body comprises a lock housing 100, a lock tongue 200, an anti-locking piece 300 and an anti-locking peach 400. The lock tongue 200 can be rotatably mounted on the lock housing 100. The lock tongue 200 can rotate between an unlocking position and a locking position. The lock tongue 200 is equipped with a magnet 230 or the lock tongue 200 has magnetism. An abutment portion 210 is arranged at one end of the lock tongue 200. The anti-locking piece 300 is rotatably mounted on the lock housing 100. The anti-locking piece 300 is located on one side of the lock tongue 200. An anti-locking portion 310 is arranged on the anti-locking piece 300. An arc-shaped anti-locking surface 311 is arranged on the outer side of the anti-locking portion 310. The center of the circle of the surface 311 is on the rotation axis of the anti-locking plate 300; the anti-locking paddle 400 is installed on the lock housing 100, and the anti-locking paddle 400 is transmission-connected with the anti-locking plate 300; wherein the anti-locking portion 310 has a first position and a second position, and the anti-locking paddle 400 drives the anti-locking portion 310 to rotate from the first position to the second position by driving the anti-locking plate 300 to rotate, and when the lock tongue 200 is in the locked position and the anti-locking portion 310 is in the second position, the abutting portion 210 abuts against the anti-locking surface 311 to limit the lock tongue 200 from rotating to the unlocking position, and when the anti-locking portion 310 is in the first position, the abutting portion 210 is out of abutment with the anti-locking surface 311.
[0029] The magnetic lock body provided by the present utility model, when the lock tongue 200 is in the locked position, can drive the anti-lock portion 310 to rotate to the second position through the anti-lock dial 400, so that the abutting portion 210 on the lock tongue 200 abuts against the anti-lock surface 311 on the anti-lock portion 310, thereby restricting the rotation of the lock tongue 200 to the unlocked position and realizing anti-lock. Among them, since the anti-lock surface 311 is arc-shaped and the center of the anti-lock surface 311 is on the rotation axis of the anti-lock piece 300, the acting force of the abutting portion 210 on the anti-lock surface 311 will point to the rotation axis of the anti-lock piece 300. Thus, without the anti-lock piece 300 being forcibly damaged, no matter how large the external acting force on the lock tongue 200 is, the acting force of the abutting portion 210 on the anti-lock surface 311 cannot drive the anti-lock piece 300 to rotate automatically, so that the lock tongue 200 remains in the anti-lock state. Therefore, the magnetic lock body provided by the present utility model can perform more reliable anti-lock on the lock tongue 200 and improve safety.
[0030] According to some embodiments of the present utility model, the magnetic lock body further includes a buckle box installed on the door frame. The buckle box is used to cooperate with the lock tongue 200 to generate a magnetic attraction force, and the magnetic attraction force is used to drive the lock tongue 200 to rotate from the unlocked position to the locked position. When the lock tongue 200 is in the locked position, the lock tongue 200 is inserted into the buckle box, thereby realizing door locking.
[0031] In the specific implementation process, one of the lock tongue 200 and the buckle box can be provided with a magnet 230 and the other has magnetism, or both the lock tongue 200 and the buckle box are provided with magnets 230. Thus, a magnetic attraction force can be generated by the mutual cooperation between the lock tongue 200 and the buckle box.
[0032] According to some embodiments of the present utility model, a first elastic member 720 is arranged between the lock tongue 200 and the lock case 100. The first elastic member 720 is used to provide a rotational force to the lock tongue 200 that is smaller than the magnetic attraction force and in the direction opposite to the magnetic attraction force. Thus, after unlocking and opening the door, before closing the door next time, the lock tongue 200 can remain in the unlocked position, avoiding the automatic rotation of the lock tongue 200 to the locked position when the door shakes or in other situations, which is convenient for closing the door again; after closing the door again, the magnetic attraction force between the buckle box and the lock tongue 200 can overcome the acting force of the first elastic member 720, so that the lock tongue 200 automatically rotates from the unlocked position to the locked position, realizing automatic door closing. Through the above settings, the magnetic lock body is more convenient to use.
[0033] According to some embodiments of the present utility model, an arc-shaped abutting surface for abutting against the anti-lock surface 311 is arranged on the abutting portion 210 to better ensure that the acting force of the abutting portion 210 on the anti-lock surface 311 points to the axis of the anti-lock piece 300.
[0034] According to some embodiments of the present utility model, one end of the locking tongue 200 is provided with a swing arm 220, and the abutting portion 210 is arranged on the swing arm 220. When the anti-locking portion 310 rotates from the first position to the second position, the anti-locking portion 310 can push the swing arm 220 to drive the locking tongue 200 to rotate from the unlocking position to the locking position. Through the above arrangement, when anti-locking is required, if the locking tongue 200 does not completely reach the locking position, the locking tongue 200 can be driven to rotate to the locking position while operating the anti-locking dial 400, so as to ensure the successful completion of anti-locking.
[0035] According to some embodiments of the present utility model, a torsion spring 710 is arranged between the anti-locking piece 300 and the lock housing 100. The torsion spring 710 is used to drive the anti-locking piece 300 to remain in the second position, so as to prevent the anti-locking state from being automatically released due to the shaking of the lock housing 100 causing the anti-locking piece 300 to rotate automatically.
[0036] Of course, in some other embodiments, a damping force can also be provided between the anti-locking piece 300 and the lock housing 100 to keep the anti-locking piece 300 in the second position.
[0037] According to some embodiments of the present utility model, the anti-locking piece 300 is rotatably installed on the lock housing 100 through a first rotating shaft 510. The lock housing 100 is provided with a first mounting post 520. The first mounting post 520 and the first rotating shaft 510 are located on the same side of the abutting portion 210. A second mounting post 530 is installed on the anti-locking piece 300. The second mounting post 530 is located between the first rotating shaft 510 and the first mounting post 520. One mounting foot 711 of the torsion spring 710 is rotatably installed on the first mounting post 520, and the other mounting foot 711 of the torsion spring 710 is rotatably installed on the second mounting post 530. Wherein, when the anti-locking portion 310 is in the first position, the second mounting post 530, the first mounting post 520 and the first rotating shaft 510 are on the same straight line, or, the second mounting post 530, the first mounting post 520 and the first rotating shaft 510 are distributed in a triangle and the second mounting post 530 is located on the side of the first mounting post 520 away from the abutting portion 210. With the above arrangement, when the anti-locking portion 310 moves to the first position, the acting force of the torsion spring 710 on the anti-locking piece 300 points to the rotation axis of the anti-locking piece 300, or, the acting force of the torsion spring 710 on the anti-locking piece 300 points to the direction away from the abutting portion 210. Thus, the torsion spring 710 cannot drive the anti-locking piece 300 to drive the anti-locking portion 310 to rotate from the first position to the second position. Thus, after the door is opened, the locking tongue 200 is in the unlocking position, and the anti-locking piece 300 will not automatically rotate under the action of the torsion spring 710 to cause the anti-locking portion 310 to move to the second position, avoiding the automatic anti-locking of the locking tongue 200 when the door is opened, resulting in the inability to directly close the door. Through the above arrangement, it can be ensured that the magnetic lock body is more convenient to use.
[0038] According to some embodiments of the utility model, a toggle portion 320 is provided on the anti-locking plate 300, and the anti-locking peach 400 drives the anti-locking plate 300 to rotate by pushing the toggle portion 320. The surface of the toggle portion 320 used to abut and cooperate with the anti-locking peach 400 is an arc surface. By adopting the above arrangement, the situation of transmission jamming between the anti-locking plate 300 and the anti-locking peach 400 can be reduced, thereby ensuring that the anti-locking peach 400 can be used flexibly.
[0039] It should be noted that in other embodiments, other transmission methods such as gear structure transmission, belt structure transmission, etc. can also be used between the above-mentioned anti-locking peach 400 and the anti-locking plate 300.
[0040] According to some embodiments of the utility model, an unlocking paddle 600 is included for installing a handle, and the unlocking paddle 600 is rotatably installed on the lock housing 100. The unlocking paddle 600 can drive the swing arm 220 to drive the lock tongue 200 to rotate from the locked position to the unlocked position. With the above arrangement, the unlocking paddle 600 can be driven by operating the handle to unlock the lock.
[0041] According to some embodiments of the present invention, the unlocking paddle 600 is provided with a toggle arm 610, and the unlocking paddle 600 pushes the swing arm 220 through the toggle arm 610. Therefore, when the anti-locking portion 310 of the anti-locking piece 300 is in the first position, the unlocking paddle 600 can directly push the swing arm 220 to swing through the toggle arm 610 to rotate the lock tongue 200 from the locked position to the unlocked position; when the magnetic lock body is in the anti-locked state, that is, when the anti-locking portion 310 of the anti-locking piece 300 is in the second position, since the swing arm 220 of the lock tongue 200 is supported by the anti-locking portion 310, even if the lock tongue 200 is subjected to external force by operating the unlocking paddle 600, the anti-locking portion 310 cannot be caused to leave the second position. Therefore, when the magnetic lock body is in the anti-locked state, the unlocking paddle 600 cannot be used to unlock the lock, and people cannot move the handle installed on the unlocking paddle 600 to the unlocking position.
[0042] According to some embodiments of the utility model, a second elastic member 730 is provided between the unlocking lever 600 and the lock housing 100. After the unlocking lever 600 drives the lock tongue 200 to rotate to the unlocking position, the second elastic member 730 can drive the unlocking lever 600 to reset. Thus, after the unlocking glue is completed, the unlocking lever 600 can automatically reset to avoid affecting the subsequent re-locking of the magnetic lock body.
[0043] It should be noted that in other embodiments, the unlocking paddle 600 can also use other methods to drive the lock tongue 200 to rotate to the unlocking position. For example, in some embodiments, an unlocking portion can be set on the anti-locking piece 300, and the unlocking portion is used to cooperate with the above-mentioned toggle arm 610. At this time, the toggle arm 610 is configured to be unable to contact with the swing arm 220. When the magnetic lock body is in the unlocking state, that is, the anti-locking portion 310 is in the first position, the toggle arm 610 can touch the unlocking portion to push the unlocking portion to rotate, and then push the swing arm 220 to drive the lock tongue 200 to rotate to the unlocking position to achieve unlocking; when the magnetic lock body is in the anti-locking state, that is, the anti-locking portion 310 is in the second position, the unlocking portion is also rotated to a position where it cannot contact with the toggle arm 610, so no matter how the unlocking paddle 600 is operated, it cannot be unlocked. With this setting, when the magnetic lock body is in the anti-locking state, the handle installed on the unlocking paddle 600 can be operated at will, but it cannot be unlocked.
[0044] According to some embodiments of the utility model, a limiting arm 620 is provided on the unlocking paddle 600, and a limiting portion 110 is provided on the lock housing 100. When the unlocking paddle 600 drives the lock tongue 200 to retract into the lock housing 100, the limiting arm 620 abuts against the limiting portion 110 to limit the rotation range of the unlocking paddle 600 when unlocking, thereby reducing the possibility that the handle rotates too much and collides with other objects or people when people operate the handle.
[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0046] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
