[0049] 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0050] The utility model relates to a door lock, comprising a lock box 100, a lock tongue 200 and a movable part 300.

[0051] like Figure 3 , Figure 5 and Figure 6 As shown, the lock box 100 is used as a mounting carrier for the first magnet 110 and the lock tongue 200. The shape of the lock box 100 is not limited, and can be a semi-enclosed box body or a frame-shaped one. The first magnet 110 is fixed on the lock box 100, and the lock tongue 200 is rotatably mounted on the lock box 100 through an axle pin. The lock tongue 200 rotates relative to the lock box 100 around the axle pin. The shape of the lock tongue 200 is not limited, and can be a long strip, a rectangular plate, etc. When the lock tongue 200 rotates relative to the lock box 100, it has two positions, which are defined as the first position and the second position of the lock tongue 200, respectively. The lock tongue 200 rotates back and forth between the first position and the second position relative to the lock box 100. A second magnet 210 is mounted on the lock tongue 200. The first magnet 110 and the second magnet 210 have a certain distance in the lock tongue 200. A first magnetic force is formed between the first magnet 110 and the second magnet 210. During the reciprocating movement of the lock tongue 200 between the first position and the second position, the first magnetic force always exists. The first magnetic force drives the locking tongue 200 to rotate from the first position to the second position to reset. Figure 1 and Figure 2 As shown, the movable member 300 can move relative to the lock box 100, and the movable member 300 can move in a translational or rotational manner. The movable member 300 has a third position and a fourth position relative to the lock box 100, and the movable member 300 can switch back and forth between the third position and the fourth position. The movable member 300 is provided with a lock slot 310 and a third magnet 320, and the lock slot 310 and the third magnet 320 move with the movable member 300.

[0052] This embodiment is described by applying the door lock to the door body. Fig.13As shown, the door body also includes a door panel 610 and a door frame 620. The door panel 610 can be slidably installed on the door frame 620 via a pulley. The door panel 610 can be a glass door, a wooden door, etc. The lock box 100 is installed on one of the door panel 610 and the door frame 620, and the movable part 300 is installed on the other. In this embodiment, the door panel 610 is installed on the door frame 620 in a sliding door style. The movable part 300 is installed on the door panel 610, and the lock box 100 is installed on the door panel 610. When the door panel 610 moves to a closed state relative to the door frame 620, the lock box 100 and the movable part 300 approach each other. Initially, the lock tongue 200 is in the second position under the action of the first magnetic force. The movable part 300 is in the fourth position relative to the lock box 100. When the door body needs to be locked, the movable part 300 is moved, and the movable part switches from the fourth position to the third position. As shown Figure 2 and Figure 7 As shown, in the third position, the lock slot 310 is aligned with the lock tongue 200, and the second magnet 210 and the third magnet 320 are opposite. A second magnetic force is formed between the second magnet 210 and the third magnet 320. The strength of the second magnetic force is greater than that of the first magnetic force, and the second magnetic force drives the lock tongue 200 to rotate from the second position to the first position. In the first position, the lock tongue 200 extends into the lock slot 310, so that the movable part 300 cannot be separated from the lock box 100 in the third position, thereby realizing the reverse locking between the door body and the door frame 620. When the lock needs to be unlocked, as shown in FIG. Figure 1 and Figure 6 The movable part 300 is manually switched from the third position to the fourth position, the second magnet 210 and the third magnet 320 are misaligned, and the second magnetic force disappears. The lock tongue 200 automatically switches from the first position to the second position under the action of the first magnetic force, so that the lock tongue 200 is disengaged from the lock slot 310, thereby achieving unlocking. The lock box 100 and the movable part 300 are located on the same side of the door body and the door frame 620, and other people cannot unlock or reverse the door from outside. The door lock of the utility model utilizes the mutual cooperation of the first magnet 110, the second magnet 210 and the third magnet 320, and utilizes the magnetic force to drive the position switching of the lock tongue 200 relative to the lock slot 310 in a contactless manner, without the need to use a spring or other mechanical component to mechanically connect the lock tongue 200, so that the action process of unlocking and reverse locking is smoother, the operation is labor-saving, the noise generated during the operation is small, the overall structure is simple, and it is easy to install and use.

[0053] Wherein, the first magnetic force and the second magnetic force can be an attraction force or a repulsion force. In the present embodiment, the first magnetic force and the second magnetic force are both repulsion force. The opposite sides of the first magnet 110 and the second magnet 210 are of the same polarity, and the opposite sides of the second magnet 210 and the third magnet 320 are of the same polarity. For example, the opposite sides of the first magnet 110 and the second magnet 210 are set to be opposite to the N pole, and the opposite sides of the second magnet 210 and the third magnet 320 are set to be opposite to the S pole. The force of the second magnetic force on the lock tongue 200 is greater than the force of the first magnetic force on the lock tongue 200. Using repulsion, the second magnet 210 and the first magnet and the third magnet 320 can be kept in a mutually separated position without contact, reducing the noise emitted during switching.

[0054] In some embodiments of the present invention, Figure 5 , Figure 6 and Figure 7 As shown, in the direction shown in the figure, the middle part of the lock tongue 200 is rotatably mounted on the lock box 100 through an axle pin. The upper end of the lock tongue 200 is the first end 201, and the lower end of the lock tongue 200 is the second end 202. The second magnet 210 is mounted on the first end 201. The second magnet 210 can be fixed on the first end 201 by means of gluing, clamping, etc. When the lock tongue 200 switches between the first position and the second position, the first end 201 swings relative to the first magnet 110, that is, drives the second magnet 210 to approach or move away from the first magnet 110. In the initial state, the lock tongue 200 is in the second position, and the first magnet 110 and the second magnet 210 move away from each other under the repulsive force of the first magnetic force. When the rotating member rotates to the third position, the third magnet 320 is closer to the second magnet 210 than the first magnet 110, so that the repulsive force strength of the second magnetic force is greater than the repulsive force strength of the first magnetic force, so that the first end 201 swings in the direction close to the first magnet 110, the lock tongue 200 rotates around the shaft pin, and the second end 202 rotates with the lock tongue 200 to extend into the lock slot 310. At this time, the groove wall of the lock slot 310 is located on both sides of the second end 202, so that the movable member 300 cannot move left and right relative to the lock tongue 200. When the movable member 300 rotates from the third position to the fourth position, the second magnetic force disappears, the first end 201 moves away from the first magnet 110 under the action of the first magnetic force, and the second end 202 swings in the direction away from the lock slot 310 to disengage from the lock slot 310.

[0055] In some specific embodiments of the present invention, Figure 5 , Figure 6 and Figure 7As shown, a slope 311 is provided in the lock slot 310, and the slope direction of the slope 311 is consistent with the slope direction when the second end 202 enters the lock slot 310. When the lock tongue 200 is switched to the first position, the second end 202 enters the lock slot 310, and the second end 202 abuts against the slope 311, thereby limiting the depth of the second end 202 entering the lock slot 310.

[0056] In some specific embodiments of the present invention, Figure 3 , Figure 5 and Figure 6 As shown, the interior of the lock box 100 is divided into a first cavity 120 and a second cavity 130, and the first cavity 120 and the second cavity 130 are distributed front and back. The first magnet 110 and the lock tongue 200 are installed in the first cavity 120, and a limit platform 121 is provided in the first cavity 120. Figure 6 As shown, when the lock tongue 200 is switched to the second position, the lock tongue 200 is in the first cavity 120 as a whole, and the second end 202 abuts on the limit platform 121. In the direction shown in the figure, the table surface of the limit platform 121 can be set as a vertical plane. When the lock tongue 200 is in the second position, the second end 202 abuts on the table surface of the limit platform 121, the lock tongue 200 is in a vertical orientation in the first cavity 120, and the lock tongue 200 is flush with the common cavity wall of the first cavity 120 and the second cavity 130. The movable member 300 rotates relative to the lock box 100, thereby switching between the third position and the fourth position. When the movable member 300 rotates to the third position, the movable member 300 can enter the second cavity 130. When the lock tongue 200 is switched to the first position, the second end 202 of the lock tongue 200 swings from the first cavity 120 to the second cavity 130, so that the second end 202 extends into the lock groove 310. When the movable member 300 switches from the third position to the fourth position, the movable member 300 withdraws from the second cavity 130 .

[0057] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 8 As shown, the movable member 300 includes a movable seat 330 and a handle 340. The handle 340, the third magnet 320 and the lock slot 310 are arranged on the movable seat 330. The handle 340 can be installed on the movable seat 330 by assembly, or the handle 340 and the movable seat 330 are integrally formed. The movable seat 330 switches and rotates between the third position and the fourth position relative to the lock box 100. When in use, the user can hold the handle 340 to operate the movable seat 330, so as to facilitate the rotation of the movable seat 330, and use the handle 340 to pull the door panel 610 to move relative to the door frame 620.

[0058] Further, such as Figure 1 , Figure 2 and Figure 8As shown, the door panel 610 further includes a fixed seat 400. The fixed seat 400 can be fixedly mounted on the door panel 610. The movable seat 330 is rotatably mounted on the fixed seat 400 via the rotating shaft 350. A limiting structure is provided between the rotating shaft 350 and the fixed seat 400. The limiting structure limits the rotation stroke of the movable seat 330 relative to the fixed seat 400, thereby determining the third position and the fourth position of the movable seat 330. The limiting structure can be that a limiting block is provided on the fixed seat 400, and the limiting block is located at the third position and the fourth position of the movable seat 330.

[0059] In some specific embodiments of the present invention, Fig. 9 , Fig.10 and Fig.11 As shown, a countersunk hole 410 in the shape of a circular segment is provided in the fixing seat 400. The circumferential inner wall of the countersunk hole 410 includes a circular wall 411 and a planar limiting wall 412, and the central axis of the circular wall 411 is the central axis of the countersunk hole 410. The radial direction of the countersunk hole 410 is perpendicular to the limiting wall 412. A connecting shaft 500 is coaxially installed in the countersunk hole 410. The circumferential outer wall of the connecting shaft 500 includes an arc surface 510, a first positioning surface 520 and a second positioning surface 530 connected in sequence. The radius of the arc surface 510 is slightly smaller than the radius of the circular wall 411. The first positioning surface 520 and the second positioning surface 530 are both perpendicular to the radial direction of the connecting shaft 500. The first positioning surface 520 and the second positioning surface 530 are perpendicular to each other, and the connection between the first positioning surface 520 and the second positioning surface 530 is a fillet 540. The connecting shaft 500 rotates coaxially in the countersunk hole 410. The rotating shaft 350 on the movable seat 330 coaxially penetrates into the countersunk hole 410 and is connected to the connecting shaft 500. The rotating shaft 350 and the connecting shaft 500 rotate synchronously relative to the countersunk hole 410. When the movable seat 330 switches between the third position and the fourth position, the arc surface 510 slides relative to the circular surface wall 411. The first positioning surface 520 and the second positioning surface 530 switch and abut against the limiting wall 412 in turn. When in the third position, the first positioning surface 520 abuts against the limiting wall 412; when in the fourth position, the second positioning surface 530 abuts against the limiting wall 412. The countersunk hole 410 and the connecting shaft 500 cooperate to form the above-mentioned limiting structure. The relative position of the first positioning surface 520 and the second positioning surface 530 can limit the rotation angle of the movable seat 330 to 90°, that is, the angle between the third position and the fourth position is 90°.

[0060] Further, such as Figure 8 and Fig.12As shown, a mounting cavity 420 is provided inside the fixed seat 400. A countersunk hole 410 is provided in the mounting cavity 420, and the countersunk hole 410 is located on the side wall of the mounting cavity 420 close to the movable seat 330. A fifth magnet 430 is provided in the mounting cavity 420. A fixing member 550 is provided on the connecting shaft 500, and the fixing member 550 is located outside the countersunk hole 410. A sixth magnet 560 is provided on the fixing member 550. The fixing member 550 rotates with the connecting shaft 500 in the mounting cavity 420. During the rotation of the fixing member 550, when the connected shaft rotates to the movable member 300 in the second position, the fifth magnet 430 and the sixth magnet 560 are opposite to each other, and a third magnetic force of mutual attraction is formed between the fifth magnet 430 and the sixth magnet. The third magnetic force can keep the fixing member 550 in the current position, and then keep the movable member 300 in the second position, and no deflection or other problems will occur. When the movable member 300 rotates away from the second position, the fifth magnet 430 and the sixth magnet 560 are misaligned, and the third magnetic force disappears.

[0061] When the door body is used in a shower room, the door panel 610 is generally a glass door. The door panel 610 and the door frame 620 are generally sealed with a rubber strip or a magnetic strip. According to the flexibility of the rubber strip or the magnetic strip, in an emergency, the user can use a tool such as a knife or a plate outside the door to penetrate the rubber strip and reach inside the door. Then, the tool is used to press down the movable part 300, so that the movable part 300 rotates and switches to the fourth position, thereby unlocking.
