[0001] This utility model belongs to the technical field of door lock products, and in particular relates to a magnetic lock body. Background Technology
[0002] Door locks are commonly used locks in daily life. A common problem with existing locks is that the secondary bolt automatically pops out after unlocking. This design can easily cause the secondary bolt to scrape against people or clothing when it pops out, causing inconvenience to the user. Especially in confined spaces or emergencies, this automatically popping secondary bolt not only increases the complexity of operation but may also create safety hazards. Therefore, there is an urgent need in the market for a lock that can solve the problem of the automatic popping of the secondary bolt, thereby improving both convenience and security. Utility Model Content
[0003] The purpose of this utility model is to provide a magnetic lock body, which aims to solve the technical problem in the prior art where the exposed lock tongue easily scratches the human body or clothing.
[0004] To achieve the above objectives, this utility model provides a magnetic lock body, comprising: a housing located on a door; a secondary lock groove located on a door frame, wherein a magnetic element is disposed within the secondary lock groove; a secondary lock tongue disposed within the housing, wherein the secondary lock tongue is movable along a first direction between a locking position protruding from the housing and a retracted position retracted into the housing; and a lever rotatably disposed within the housing, wherein the lever is configured to force the secondary lock tongue to move from the locking position to the retracted position when rotated; when the door and the door frame are engaged, the magnetic element attracts the secondary lock tongue, causing the secondary lock tongue to move to the locking position.
[0005] Optionally, the secondary locking tongue is provided with a baffle at one end inside the housing, the lever rotates between a first angle position and a second angle position, and a lever is provided protruding on the lever. During the process of the lever rotating from the first angle position to the second angle position, the lever pushes the baffle to move the secondary locking tongue from the locking position to the retracted position.
[0006] Optionally, the housing is provided with a first stop and a second stop. When the lever is located at the first angle position, the lever abuts against the first stop. When the lever is located at the second angle position, the lever abuts against the second stop.
[0007] Optionally, the first stop block has a through groove in the middle, and the secondary lock tongue has a guide rod, which is slidably disposed in the through groove along the first direction.
[0008] Optionally, a first torsion spring is provided between the lever and the housing, the first torsion spring being configured to cause the lever to always have a tendency to rotate from the second angular position to the first angular position.
[0009] Optionally, it also includes a connecting rod, a main bolt, and a lock cylinder. The lock cylinder is rotatably disposed within the housing and has a protruding top block. The lock cylinder is configured to drive the main bolt to move along a first direction from a first position protruding from the housing to a second position retracted into the housing when rotating, via the top block. One end of the connecting rod is hinged to the lever, and the other end is slidably hinged to the main bolt. When the main bolt is in the second position, the top block can push the connecting rod as the lock cylinder rotates, causing the lever to rotate from the first angular position to the second angular position.
[0010] Optionally, the connecting rod is provided with a triangular limiting groove, and the main locking tongue is provided with a limiting post, which is accommodated in the limiting groove.
[0011] Optionally, a second torsion spring is provided within the housing, the second torsion spring being configured to cause the main locking tongue to always have a tendency to move from the second position to the first position.
[0012] Compared with the prior art, the above-mentioned technical solutions of one or more of the magnetic lock bodies provided in this utility model embodiment have at least one of the following technical effects: When the door is in a closed state, the door is fastened to the door frame. At this time, the secondary lock tongue is attracted to the locking position by the magnetic force in the secondary lock groove, that is, it enters the secondary lock groove and plays the role of locking the door. When unlocking, the lever is subjected to rotational force, and the rotating lever can force the secondary lock tongue to move from the locking position to the retracted position, thereby realizing the door opening action. After the door is opened, since the secondary lock tongue is not attracted by the magnetic force, the secondary lock tongue can always remain in the retracted position when the door is open, which can effectively prevent the secondary lock tongue from being exposed when the door is opened, thus preventing the secondary lock tongue from scratching the body and clothing.

[0029] like Figure 1 and Figure 2 The present invention provides a magnetic lock body, including a housing 100, a secondary lock groove 200, a secondary lock tongue 300, and a lever 400.
[0030] The system comprises: a housing 100 located on the door body; a secondary lock groove 200 located on the door frame, wherein a magnetic element (not shown in the figure) is provided within the secondary lock groove 200; a secondary lock tongue 300 disposed within the housing 100, wherein the secondary lock tongue 300 is movable along a first direction between a locking position protruding from the housing 100 and a retracted position retracted within the housing 100; and a lever 400 rotatably disposed within the housing 100, wherein the lever 400 is configured to force the secondary lock tongue 300 to move from the locking position to the retracted position when rotated; and when the door body and the door frame are engaged, the magnetic element attracts the secondary lock tongue 300 to move the secondary lock tongue 300 to the locking position.
[0031] Understandably, when the door is closed, it is locked to the door frame. At this time, the secondary latch 300 is attracted to the locking position by the magnetic element within the secondary lock groove 200, thus locking the door. When unlocking, the lever 400 is subjected to rotational force, which forces the secondary latch 300 to... Figure 1 The locking position shown is moved to Figure 2 The door opens when the secondary latch 300 is in the retracted position shown in the diagram. After the door is opened, the secondary latch 300 is not attracted by the magnetic component. Therefore, the secondary latch 300 can always remain in the retracted position when the door is open, which can effectively prevent the secondary latch 300 from being exposed and scratching the body or clothing when the door is opened.
[0032] It should be noted that the magnetic component in this utility model can be a permanent magnet or an electromagnet, and correspondingly, the secondary locking tongue 300 is at least partially composed of a magnetic material that can be attracted by a magnet.
[0033] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the secondary locking tongue 300 is provided with a baffle 310 at one end inside the housing 100, and the toggle block 400 is in... Figure 1 The first angular position shown and Figure 2 The lever 400 is provided with a protruding paddle 410 when rotating between the first and second angular positions. During the rotation of the lever 400 from the first angular position to the second angular position, the paddle 410 pushes the stop 310 to cause the secondary locking tongue 300 to move along the first direction from the first angular position. Figure 1 The locking position shown is moved to Figure 2 The contraction position is shown.
[0034] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, a first stop 110 and a second stop 120 are provided inside the housing 100. When the lever 400 is in a first angular position, the lever 410 abuts against the first stop 110; when the lever 400 is in a second angular position, the lever 410 abuts against the second stop 120. The first stop 110 and the second stop 120 can limit the rotation angle of the lever 400.
[0035] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, a through groove 111 is provided in the middle of the first stop block 110, and the through groove extends through the first stop block 110 along a first direction. The secondary locking tongue 300 has a guide rod 320, which is slidably disposed in the through groove 111 along the first direction. The through groove 111 can provide guidance for the guide rod 320, thereby ensuring that the secondary locking tongue 300 can slide stably along the first direction.
[0036] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, a first torsion spring 130 is provided between the lever 400 and the housing 100. The first torsion spring 130 is configured to cause the lever 400 to always have a tendency to rotate from the second angular position to the first angular position. When the lever 400 is not subjected to external force, the first torsion spring 130 can drive the lever 400 from the second angular position to the first angular position. Figure 2 The second angular position shown is towards Figure 1 Rotating the first angular position shown achieves automatic reset of the toggle block 400.
[0037] It should be noted that in embodiments where the first torsion spring 130 is not provided, when the secondary locking tongue 300 is attracted by the magnetic component and moves in the opposite direction from the retracted position to the locked position, the baffle 310 pushes the paddle 410 to rotate the paddle 400 from the second angle position to the first angle position.
[0038] like Figure 1 and Figure 2As shown, in some embodiments of this utility model, a connecting rod 500, a main bolt 600, and a lock cylinder 700 are also included. The lock cylinder 700 is rotatably disposed within the housing 100 and has a protruding top block 710. The lock cylinder 700 is configured to drive the main bolt 600 to move along a first direction from a first position protruding from the housing 100 to a second position retracted into the housing 100 when rotating, via the top block 710. One end of the connecting rod 500 is hinged to the lever 400, and the other end is slidably hinged to the main bolt 600. When the main bolt 600 is in the second position, the top block 710 can push the connecting rod 500 with the rotation of the lock cylinder 700 to rotate the lever 400 from the first angle position to the second angle position.
[0039] When the door is locked onto the door frame, the main bolt 600 can be inserted by turning the lock cylinder 700. Figure 1 The main lock slot is 800.
[0040] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, a triangular limiting groove 510 is provided on the connecting rod 500, and a limiting post 610 is provided on the main locking tongue 600, with the limiting post 610 housed in the limiting groove 510.
[0041] In some embodiments of this utility model, a second torsion spring 140 is provided inside the housing 100. The second torsion spring 140 is configured to cause the main locking tongue 600 to always have a tendency to move from the second position to the first position.
[0042] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
[0043] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
