[0033] The following details the embodiments of the present application. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as limiting the present application.

[0034] Please refer to Figures 1 to 6, this application discloses a glass door and its magnetic lock. Among them, the glass door includes a glass door body, a door leaf frame, a door pocket frame and a magnetic lock. The door leaf frame is the outer frame of the glass door body. The door pocket frame is fixed on building structures such as walls. The magnetic lock is installed on the door leaf frame and the door pocket frame of the glass door. The glass door body does not need to be drilled, which can reduce the difficulty of the glass door body and installation. And the magnetic lock of this application can be locked by lifting the handle, and it is impossible to unlock through the handle outside the door, which can ensure the use safety of the glass door.

[0035] Specifically, the magnetic lock includes a magnetic lock body 1, a magnetic attraction buckle plate 2 and a handle. The magnetic lock body 1 is installed on the door leaf frame of the glass door. The magnetic attraction buckle plate 2 is installed on the door pocket frame. The handle includes an outer handle 302 and an inner handle 301 respectively arranged on both sides of the door leaf inside and outside, and both the outer handle 302 and the inner handle 301 are connected to the magnetic lock body 1. Then the handle is connected to the door leaf through the magnetic lock body 1, that is, the purpose of installing the handle without opening a hole in the glass door body is achieved.

[0036] The magnetic lock body 1 includes a lock body installation shell 11, a lock tongue 12 and a lock body slider 13. Among them, the lock body installation shell 11 includes a lock body installation bottom plate 111, a lock body bottom shell 112, a lock body cover plate 113 and a lock body panel 114. One side of the lock body installation bottom plate 111 forms an installation groove (not marked) for inserting the glass door body. The lock body bottom shell 112 is arranged on the side of the lock body installation opposite to the side where the installation groove is opened. Two lock body cover plates 113 are arranged on both sides of the lock body bottom shell 112 respectively. The lock body panel 114 is arranged on the side edge of the door leaf frame and is connected to the lock body installation bottom plate 111 to encapsulate the lock body bottom shell 112 between the lock body panel 114 and the lock body installation bottom plate 111. At the same time, a through groove 1141 is opened on the lock body panel 114. The lock tongue 12 is hinged on the lock body bottom shell 112 and enters and exits the lock body installation shell 11 through the through groove 1141 on the lock body panel 114.

[0037] The lock tongue 12 can rotate relative to the lock body installation shell 11. Rotating shafts 1131 are provided on both lock body cover plates 113 located on both sides of the lock body bottom shell 112 to be connected to the lock tongue 12. At the same time, a lock tongue torsion spring 121 connected to the lock tongue 12 is provided on the rotating shaft 1131. Then, when the lock tongue torsion spring 121 does not undergo any elastic deformation, the lock tongue 12 is located in the lock body installation shell 11, and when the lock tongue 12 pops out of the lock body installation shell 11 under the magnetic attraction of the magnetic attraction buckle plate 2, the lock tongue torsion spring 121 undergoes elastic deformation.

[0038] The lock body slider 13 is also arranged in the lock body mounting shell 11. The lock body slider 13 can slide up and down along the height direction of the lock body mounting shell 11. A chute 131 extending along its height direction is provided on the lock body slider 13. The rotating shaft 1131 on the lock body cover plate 113 of the lock body mounting shell 11 can pass through the chute 131 to be connected with the lock tongue 12. And, a limiting groove 1132 extending along its height direction is formed on the lock body cover plate 113. Limiting blocks inserted into the limiting groove 1132 are provided on both sides of the lock body slider 13. Then, the cooperation between the chute 131 and the rotating shaft 1131, and the cooperation between the limiting blocks and the limiting groove 1132 can limit the up and down sliding of the lock body slider 13.

[0039] The magnetic attraction buckle plate 2 is installed on the door frame border through screws. A lock groove 21 is formed at the same height position as the lock tongue 12 on the magnetic attraction buckle plate 2. A magnet is arranged in the lock groove 21. When the lock tongue 12 approaches the magnetic attraction buckle plate 2, it can be attracted by the magnet in the lock groove 21 to rotate and extend into the lock groove 21, thereby realizing the locking between the door leaf and the door frame. When the lock tongue 12 is attracted by the magnet and extends into the lock groove 21, the lock tongue torsion spring 121 undergoes elastic deformation.

[0040] The unlocking between the magnetic attraction buckle plate and the magnetic attraction lock body 1 is realized through the inner handle 301 or the outer handle 302. Both the inner handle 301 and the outer handle 302 include a handle 31 provided with a transmission shaft 32. The handle 31 is vertically arranged with the transmission shaft 32, and the transmission shaft 32 is rotated by rotating the handle 31. A turntable 33, a handle panel 34, an unlocking rotating plate 35 and a transmission plate are sequentially sleeved on the transmission shaft 32. The turntable 33 can rotate relative to the rotating shaft. The handle panel 34 is fixed to the lock body mounting bottom plate 111 of the lock body mounting shell 11 through screws. The turntable 33 can rotate relative to the handle panel 34, and an elastic locking member 333 is arranged between the turntable 33 and the handle panel 34. The unlocking rotating plate 35 can also rotate relative to the transmission shaft 32. The unlocking rotating plate 35 is connected with the turntable 33 and the two rotate coaxially. The transmission shaft 32 is connected with the transmission plate so that the transmission plate rotates coaxially with the transmission shaft 32. The transmission plate is used to push the lock tongue 12 to rotate under the drive of the transmission shaft 32.

[0041] Specifically, a clamping groove is formed on the transmission shaft 32, and a clamping block 363 that can be embedded in the clamping groove is arranged inside the transmission plate. The coaxial rotation between the transmission plate and the transmission shaft 32 can be realized through the cooperation of the clamping groove and the clamping block 363. At the same time, a push rod 364 is arranged on the transmission plate. An end of the lock tongue 12 hinged to the lock body mounting shell 11 is provided with a rotating rod 122 extending towards the handle direction. The push rod 364 is located below the rotating rod 122. By downwardly rotating the handle 31 of the handle, the push rod 364 rotates upward with the transmission plate to push the rotating rod 122 to rotate upward. The lock tongue 12 takes the rotating shaft 1131 of the lock body cover plate 113 as the hinge point. When the rotating rod 122 rotates upward, the lock tongue 12 rotates downward and returns to the lock body mounting shell 11, thereby realizing the unlocking between the magnetic absorption lock body 1 and the magnetic absorption clamping plate 2.

[0042] Since in this application, the unlocking between the magnetic absorption lock body 1 and the magnetic absorption clamping plate 2 can be realized by downwardly rotating the handle 31 through both the inner handle 301 and the outer handle 302, two rotating rods 122 are arranged side by side on both sides of the lock tongue 12 in this embodiment for the transmission plates in the inner handle 301 (i.e., the inner transmission plate 361) and the outer handle 302 (i.e., the outer transmission plate 362) to push and unlock respectively.

[0043] The unlocking rotating plate 35 is connected to the turntable 33 and rotates coaxially. A positioning groove 331 is formed on the turntable 33. The unlocking rotating plate 35 is provided with a positioning block 351 extending towards the turntable 33 direction and passing through the handle panel 34. The positioning block 351 is inserted into the positioning groove 331 to realize the connection between the two. To improve the connection stability between the unlocking rotating plate 35 and the turntable 33, positioning blocks 351 are arranged on both the upper and lower sides of the unlocking rotating plate 35, and the turntable 33 is provided with two positioning grooves 331 corresponding to the two positioning blocks 351. At the same time, an arc groove 341 is arranged on the handle panel 34 along the moving path of the positioning block 351. The positioning block 351 passes through the arc groove 341 and is inserted into the positioning groove 331 to be connected to the turntable 33.

[0044] In addition, the unlocking rotating plate 35 is connected to the lock body slider 13, and the handle 31 of the handle can be rotated upward to cause the lock body slider 13 to slide downward, so as to lock the lock tongue 12. A U-shaped block 352 is provided on the unlocking rotating plate 35, and a convex block 132 is provided on the lock body slider 13. The convex block 132 is located between the grooves of the U-shaped block 352. When the unlocking rotating plate 35 rotates, the convex block 132 is pushed by its U-shaped block 352 to drive the lock body slider 13 to slide up and down. At the same time, a first flanging 353 is provided on the unlocking rotating plate 35 of the handle in the direction towards the transmission plate, and a second flanging 365 is also provided on the transmission plate in the direction towards the unlocking rotating plate 35. The first flanging 353 of the unlocking rotating plate 35 is located between the second flanging 365 of the transmission plate and the push rod 364. When the handle 31 of the handle is rotated upward, the second flanging 365 rotates with its transmission plate towards the direction of the first flanging 353, so that the first flanging 353 of the unlocking rotating plate 35 flips downward, and then the U-shaped block 352 of the unlocking rotating plate 35 drives the lock body slider 13 to slide downward.

[0045] A pressing rod 366 parallel to the push rod 364 is provided on one side of the transmission plate (i.e., the outer transmission plate 362) in the outer handle 302 close to the unlocking rotating plate 35. At the same time, a flanging 133 is formed by folding the bottom side of the lock body slider 13 outward. After the lock body slider 13 slides downward driven by the unlocking rotating plate 35, it abuts against the pressing rod 366 to limit the upward rotation of the push rod 364 of the outer transmission plate 362 to push the rotating rod 122 of the lock tongue 12 for unlocking.

[0046] An elastic locking member 333 provided between the handle panel 34 and the turntable 33 is used to temporarily lock the position of the unlocking rotating plate 35. The elastic locking member 333 includes a positioning spring 3331 and a positioning bead 3332. A positioning hole 332 is provided on the turntable 33. The positioning spring 3331 is arranged in the positioning hole 332, and the positioning bead 3332 is arranged at the end of the positioning spring 3331 outside the positioning hole 332. At the same time, a first lock hole 342 and a second lock hole 343 are provided on the handle panel 34. The first lock hole 342 is used to correspond to the unlocking state of the magnetic lock, and the second lock hole 343 is used to correspond to the locking state of the magnetic lock. A connecting groove 344 is provided between the first lock hole 342 and the second lock hole 343, and the shape of the connecting groove 344 is the same as the track of the positioning bead 3332.

[0047] A handle torsion spring 37 is further provided between the unlocking rotating plate 35 and the transmission plate. One end of the handle torsion spring 37 is connected to the transmission shaft 32, and the other end is connected to the handle panel 34. Then, under the action of an external force, when the handle 31 of the handle rotates upward or downward, the transmission shaft 32 rotates, causing the handle torsion spring 37 to undergo elastic deformation. After the external force is removed, the transmission shaft 32 returns to its original position under the elastic recovery action of the handle torsion spring 37, that is, the handle 31 of the handle returns to its original position.

[0048] A snap ring 38 is provided at the end of the transmission shaft 32 to limit the unlocking rotating plate 35, the handle torsion spring 37, and the transmission sleeved on the transmission shaft 32 to the transmission shaft 32, preventing the above structures from shifting during the rotation of the handle and affecting subsequent unlocking and locking operations.

[0049] The handle further includes a handle bottom plate 39 and a handle mounting pad 310 provided at the end of the transmission shaft 32. The handle bottom plate 39 is connected to the end of the transmission shaft 32 to support the transmission shaft 32, and the handle mounting pad 310 is used to be in contact with the glass door body. By means of the handle mounting pad 310, the friction between the handle and the glass door body is increased, improving the stability of the handle. At the same time, the setting of the handle mounting pad 310 can prevent damage to the glass door body when the handle is used.

[0050] A door lock indicator (not shown) is further provided on the outer side of the handle. When the magnetic lock is in the unlocked state, the door lock indicator indicates green, and when the magnetic lock is in the locked state, the door lock indicator indicates red.

[0051] In addition, an operation groove 311 is provided on the outer side of the handle. The operation groove 311 can communicate with the inside of the handle. An unlocking hole 334 is provided on the turntable 33. The user can insert a tool such as a screwdriver into the unlocking hole 334 of the turntable 33 through the operation groove 311 to rotate the turntable 33 and thus achieve the purpose of unlocking.

[0052] In summary, when the magnetic lock of the present application is installed on a glass door, the magnetic lock body 1 is installed on the door leaf frame, the magnetic attraction buckle plate 2 is installed on the door pocket frame, the lock tongue 12 can be rotated to retract into the lock body installation shell 11 to hide or rotate and extend under the action of the magnetic attraction of the magnet of the magnetic attraction buckle plate 2, and the operating handle can move the lock tongue 12 out of the lock slot 21 of the magnetic attraction buckle plate 2 and automatically reset and retract into the lock body installation shell 11 to hide, thereby realizing the unlocking between the magnetic lock body 1 and the magnetic attraction buckle plate 2, so that the glass door can be opened. In addition, when using the magnetic lock of the present application, the magnetic lock can also be locked by rotating the inner and outer handles or the handle 31 of the inner handle 301 upward, and the outer handle 302 cannot be unlocked.

[0053] Specifically, when the glass door is in the open state, the lock tongue 12 is located inside the lock body installation shell 11 under the action of its lock tongue torsion spring 121, and neither the inner transmission plate 361 of the inner handle 301 nor the outer transmission plate 362 of the outer handle 302 is in contact with the rotating rod 122 at the end of the lock tongue 12. At this time, when the handle 31 of the inner handle 301 or the outer handle 302 is rotated downward, it is in an idle rotation state.

[0054] Then, when the glass door is pushed closed and unlocked, the magnetic lock body 1 on the door leaf approaches the magnetic buckle plate 2 on the door cover, and the lock tongue 12 is attracted by the magnet in the magnetic buckle plate 2 and rotates out of the lock body mounting shell 11. The rotating rod 122 at the end of the lock tongue 12 rotates with the lock tongue 12 and contacts the push rod 364 of the inner transmission plate 361 and the outer transmission plate 362. At this time, the user can push down the inner handle 301 or the outer handle 302, so that the push rod 364 on the inner handle 301 or the outer handle 302 pushes the rotating rod 122 to rotate upward, so that the lock tongue 12 can rotate back into the lock body mounting shell 11. At this time, the unlocking rotating plate 35 of the inner handle 301 and the outer handle 302 is in the upper end position and is positioned at the position of the first lock hole 342 by the elastic locking member 333, and the lock body slider 13 is in the unlocking position. Since the unlocking rotating plate 35 rotates coaxially with the rotating disk 33, the door lock status indicator on the outside of the handle indicates green, i.e., unlocked state. When the outer handle 302 is pressed down, there is no contact limit between the pressing rod 366 of the outer transmission plate 362 and the lock body slider 13 and the pressing rod 366 can rotate freely relative to the outer handle 302, so that the magnetic lock can be unlocked by the outer handle 302. Since there is no pressing rod 366 or other forward protruding structure below the push rod 364 of the inner transmission plate 361 of the inner handle 301, there is no contact limit between the inner transmission plate 361 and the lock body slider 13, so that the inner handle 301 can always unlock the magnetic lock. That is, when the glass door is closed and not locked on the outside, both the inner handle 301 and the outer handle 302 can be unlocked, the magnetic lock is in the passage state, and the door lock status indicator is displayed in green.

[0055] When the glass door is closed and needs to be locked, the transmission shaft 32 drives the inner transmission plate 361 or the outer transmission plate 362 to rotate by turning the inner handle 301 or the outer handle 302 upward, so as to push the first flange 353 through the second flange 365 thereon, so that the U-shaped block 352 of the unlocking rotating plate 35 rotates downward to the lower end position, thereby linking the lock body to slide downward to the lower end position, and when the outer handle 302 is pressed down and rotated, the pressing rod 366 under the outer transmission plate 362 contacts the lock body slider 13 and is limited, so that it cannot rotate, and then the outer handle is locked. At the same time, the unlocking rotating plate 35 will drive the rotating disk 33, so that the door lock status indicator on the outer side of the handle is displayed in red, that is, the glass door is in a locked state.

[0056] When the glass door is in the locked state, the outer handle 302 cannot be unlocked, but the magnetic lock can be unlocked by turning the inner handle 301. When the user presses down and turns the inner handle 301, the push rod 364 of the inner rotating plate can be driven to rotate to the rotating rod 122 at the end of the lock tongue 12. By pushing the rotating rod 122 with the push rod 364, the lock tongue 12 retracts to achieve the purpose of opening the door. At the same time, the second flange 365 on the inner transmission plate 361 pushes the first flange 353, so that the U-shaped block 352 of the unlocking rotating plate 35 rotates upward to the upper end position, and the lock body slider 13 is linked to slide upward to the upper end position. Then, when the outer handle 302 is pressed down and turned, there is no contact between the pressing rod 366 of the outer transmission plate 362 inside it and the flange 133 of the lock body slider 13, so it can rotate freely, thus realizing the unlocking of the outer handle 302. At this time, the door lock status indicator shows green, and the magnetic lock restores the channel state where it can be opened from both inside and outside.
