Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a magnetic lock. Background Technology

[0002] Magnetic locks are structures that use magnetic attraction. When closing doors and windows, the magnetic components of the door frame attract the magnetic latch installed on the door or window, achieving an automatic locking effect. To open the door or window, simply overcome the magnetic force between the magnetic components and the magnetic latch, detaching the magnetic latch from the magnetic components and the door / window frame, and the door or window can be opened. For glass doors and windows, installing a magnetic latch requires creating a notch in the glass to accommodate the magnetic latch and its matching casing, making the installation process more complex. Utility Model Content

[0003] The purpose of this utility model is to provide a magnetic lock to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: A magnetic lock, comprising: a first handle connected to a mounting frame; a latch assembly including a housing mounted on the mounting frame and a magnetic latch block slidably disposed within the housing, the housing, the magnetic latch block and the mounting frame being disposed flush on one side, and an elastic element installed between the magnetic latch block and the inner side of the housing to keep the magnetic latch block within the housing; a lock cylinder rotatably mounted within the housing, and a lever being mounted on the outer periphery of the lock cylinder; a sliding piece slidably disposed within the housing, the sliding piece having a lever groove, the sliding piece being connected to the magnetic latch block, and when the magnetic latch block extends out of the housing against the elastic force of the elastic element, the lock cylinder can be rotated to cause the lever to abut against the side wall of the lever groove, thereby causing the sliding piece to slide and the magnetic latch block to retract into the housing.

[0005] This technical solution has at least the following beneficial effects: When installing the magnetic latch block, the first handle only needs to be installed on one side of the glass door or window to achieve the installation of the latch assembly, without the need to open a notch in the glass door or window for the latch assembly to be embedded separately, thus improving the efficiency of the latch assembly installation. At the same time, the overall structure is simpler and more aesthetically pleasing, making it more suitable for frameless glass doors and windows.

[0006] As a further improvement to the above technical solution, the housing includes a frame cover and a plate cover. The frame cover is threaded with a first screw, and one end of the plate cover is engaged with one end of the frame cover, while the other end is assembled with the other end of the frame cover via the first screw. Opening the frame cover and the plate cover facilitates the installation of the magnetic locking tongue block, elastic element, lock cylinder, and sliding plate inside the housing, thereby improving assembly efficiency.

[0007] As a further improvement to the above technical solution, both the frame cover and the plate cover have stepped holes on opposite sides, and both ends of the lock cylinder have stepped structures that can be fitted into the stepped holes. This facilitates the assembly of the lock cylinder, and the structure is relatively simple and the manufacturing cost is low.

[0008] As a further improvement to the above technical solution, ribs are provided on the opposite side of the frame cover and the sheet cover. Sliding grooves are formed between the side wall of the frame cover and the corresponding ribs, and between the sheet cover and the corresponding ribs, respectively, for the sliding pieces to be inserted and slid. This facilitates the assembly of the sliding pieces, and the structure is relatively simple with low manufacturing costs.

[0009] As a further improvement to the above technical solution, fan-shaped limiting grooves are provided on both sides of the housing, and the lock cylinder protrudes with limiting protrusions that slide within the fan-shaped limiting grooves. This is to limit the rotation range of the lock cylinder and improve its stability.

[0010] As a further improvement to the above technical solution, the mounting frame has a notch on the side away from the first handle for mounting the first handle and the locking tongue assembly. A cover plate is provided at the notch position, and a second screw is installed on the mounting frame. The cover plate is assembled with the mounting frame by the second screw.

[0011] As a further improvement to the above technical solution, the mounting frame and the cover plate are connected by mounting screws, and the housing is provided with an elongated slot for both the mounting screw and the second screw to pass through. The elongated slot is located between the magnetic latch block and the lock cylinder.

[0012] As a further improvement to the above technical solution, the housing is provided with a clearance slot corresponding to the actuating groove. This reduces the overall width of the housing, making the structure more refined and compact.

[0013] As a further improvement to the above technical solution, the elastic element is a helical spring, and both the magnetic locking tongue block and the housing form connecting posts. Each end of the helical spring is provided with a connecting ring that can be respectively fitted onto the two connecting posts. This facilitates the installation of the helical spring and is cost-effective and economical.

[0014] As a further improvement to the above technical solution, a magnetic lock also includes a fixed locking block. A locking groove is formed on one side of the fixed locking block, and a magnetic element that can attract the magnetic latch block is installed inside the locking groove. The fixed locking block is installed on a frameless glass door / window frame on the same side as the first handle. When the glass door / window is closed, the magnetic latch block automatically engages with the fixed locking block to achieve automatic locking. Therefore, it can be adapted to frameless glass doors / windows and door / window frame structures, and has a wide range of applications. Attached Figure Description

[0026] Reference Figure 1-5 The magnetic lock includes a first handle 100, a mounting frame 200, and a latch assembly 300. The first handle 100 is rotatably mounted on one side of the mounting frame 200. A receiving groove 201 is provided on the side of the mounting frame 200 adjacent to the mounting position of the first handle 100, and a notch 210 is provided on the side of the mounting frame 200 away from the first handle 100, connecting to the receiving groove 201. A cover plate 220 is provided at the notch 210 position of the mounting frame 200, which better covers the notch 210. Two countersunk holes are provided on the cover plate 220, and two second screws 230 corresponding to the countersunk holes are threaded onto the inner side of the mounting frame 200. The two second screws 230 are located on both sides of the connection position between the first handle 100 and the mounting frame 200. Therefore, the cover plate 220 and the mounting frame 200 can be assembled and installed using the second screws 230.

[0027] The latch assembly 300 includes a housing 400 and a magnetic latch block 500, an elastic element, a lock cylinder 600, and a sliding piece 700 installed within the housing 400. The housing 400 can be inserted into the receiving groove 201 either through an opening or through a notch 210. One side of the housing 400 is flush with the side of the mounting frame 200 that has the receiving groove 201.

[0028] The magnetic latch block 500 is slidably disposed inside the housing 400, with one side of the magnetic latch block 500 flush with the side of the housing 400 that is flush with the mounting frame 200. It can be understood that the magnetic latch block 500 can slide out of the housing 400. The elastic element is a helical spring 510, with connecting rings 512 integrally formed at both ends. Connecting posts 511 are installed inside the magnetic latch block 500 and inside the housing 400. The connecting ring 512 at one end of the helical spring 510 is fitted into the connecting post 511 inside the magnetic latch block 500, and the connecting ring 512 at the other end of the helical spring 510 is fitted into the connecting post 511 on the housing 400. The helical spring 510 is in a stretched state, allowing it to exert a pulling force to keep the magnetic latch block 500 within the housing 400 and prevent it from extending out.

[0029] There are two sliding pieces 700, which are slidably disposed on both sides inside the housing 400. One end of each sliding piece 700 is fixedly connected to one end of the helical spring 510 connected to the magnetic locking tongue block 500, and the other end abuts against the inner wall of the housing 400 away from the protruding end of the magnetic locking tongue block 500. That is, the magnetic locking tongue block 500 and the sliding pieces 700 are held inside the housing 400 by the elastic force of the helical spring 510. Because one end of the sliding piece 700 abuts against the inner wall of the housing 400, one side of the magnetic locking tongue block 500 can be exactly flat with one side of the housing 400, or that side of the magnetic locking tongue block 500 can extend slightly into the inner side of the housing 400.

[0030] The lock cylinder 600 is rotatably mounted inside the housing 400. Two levers 610 are integrally formed on both sides of the lock cylinder 600, symmetrically distributed around the midpoint of both sides of the housing 400. Two sliding pieces 700 are each fitted with a corresponding actuation slot 710. A square hole is formed inside the lock cylinder 600, and a square shaft that passes through the square hole is connected to the first handle 100. When locked, the magnetic latch 500 is attracted and extends out of the housing 400 and mounting frame 200, overcoming the elastic force of the coil spring 510. Rotating the first handle 100 causes the square shaft to rotate, thus rotating the lock cylinder 600. After rotation, one of the levers 610 presses against the actuation slot 710 on the side away from the extended magnetic latch 500, pushing the sliding piece 700 to retract into the housing 400, overcoming the attraction force, thus unlocking the lock cylinder.

[0031] When the magnetic latch block 500 slides back into the housing 400, the elastic force of the helical spring 510 also assists the magnetic latch block 500 in sliding, thereby reducing the force required to rotate the first handle 100 and achieving the effect of saving effort. At this time, the magnetic latch block 500 also remains inside the housing 400 under the elastic force of the helical spring 510, thus preventing the magnetic latch block 500 from extending out of the housing and potentially causing injury.

[0032] The housing 400 includes a frame cover 410 and a plate cover 420. One side of the frame cover 410 has a cavity to accommodate a magnetic latch block 500, a coil spring 510, a lock cylinder 600, and a sliding plate 700. The plate cover 420 covers the opening of the cavity in the frame cover 410 to facilitate the assembly of the internal structures of the housing 400. One side of the frame cover 410 has an end frame with a slot, and the other side of the frame cover 410 is threaded with a first screw 430. One end of the plate cover 420 has an integrally formed locking block, and the side of the plate cover 420 away from the locking block has a countersunk hole through which the first screw 430 passes. The locking block at one end of the plate cover 420 is laterally inserted into the slot, locking the plate cover 420 to the frame cover 410. The first screw 430 then passes longitudinally through the countersunk hole of the plate cover 420 and is threaded into the frame cover 410, thus securing the plate cover 420 to the frame cover 410.

[0033] The magnetic locking tongue block 500 is slidably disposed at one end of the frame cover 410 near the end frame, and the magnetic locking tongue block 500 can extend out of the frame cover 410 from the end frame. The connecting post 511 on the housing 400 is mounted on the bottom side of the frame cover 410.

[0034] Both the frame cover 410 and the plate cover 420 have stepped holes 620 on opposite sides. Each stepped hole 620 is formed by two holes of different radii connected coaxially, giving the inner side of the stepped hole 620 a stepped shape. Both ends of the lock cylinder 600 have annular grooves, forming stepped structures 630 at both ends that match the stepped holes 620. Both the stepped holes 620 and the stepped structures 630 are circular. The stepped structure 630 at one end of the lock cylinder 600 is inserted into the stepped hole 620 of the frame cover 410. When installing the plate cover 420, the stepped structure 630 at the other end of the lock cylinder 600 is also inserted into the stepped hole 620 of the plate cover 420. The lock cylinder 600 can rotate relative to the frame cover 410 and the plate cover 420, thus achieving the assembly of the lock cylinder 600.

[0035] Both the frame cover 410 and the plate cover 420 have fan-shaped limiting grooves 640 that connect to the corresponding stepped holes 620. Limiting protrusions 650 protrude from both sides of the lock cylinder 600. The side walls of the fan-shaped limiting grooves 640 restrict the swinging of the limiting protrusions 650, thereby limiting the rotation range of the lock cylinder 600. For example, when the toggle block 610 pushes the sliding plate 700 to fully extend the magnetic latch block 500 into the housing 400, the limiting protrusions 650 just move to one end of the fan-shaped limiting groove 640, thus limiting the lock cylinder 600 from continuing to rotate and ensuring the stability of the lock cylinder 600 when it is at either end of its rotation range.

[0036] Both sides of the frame cover 410 and the sheet cover 420 have integrally formed protruding ribs 720. A groove 730 is formed between the rib 720 installed on the frame cover 410 and its side wall, allowing one side of the sliding piece 700 to slide. Similarly, a groove 730 is formed between the rib 720 installed on the sheet cover 420 and its side wall, allowing the other side of the sliding piece 700 to slide. When the magnetic locking tongue block 500 and the sliding piece 700 are installed on the frame cover 410, the sliding piece 700 is confined to the groove 730 of the frame cover 410. When the sheet cover 420 is installed, the other side of the sliding piece 700 is also embedded in the groove 730 of the sheet cover 420, thus allowing the sliding piece 700 to slide stably within the housing 400. This facilitates the assembly of the sliding piece 700.

[0037] On both sides of the opening where the frame cover 410 and the plate cover 420 close, there are clearance slots 441. The two clearance slots 441 on each side are respectively distributed with the corresponding actuation slots 710 on the corresponding side. When the actuation block 610 of the lock cylinder 600 abuts against the side wall of the actuation slot 710, the actuation block 610 is partially embedded in the clearance slot 441, which can ensure that the actuation block 610 can stably actuate the sliding plate 700, and at the same time, it can also reduce the overall width of the housing 400, making the overall structure more compact.

[0038] Mounting screws 240 pass through both the mounting frame 200 and the cover plate 220. Two mounting screws 240 are provided, located on either side of the first handle 100. These screws facilitate fixing the mounting frame to the glass door or window, achieving secure installation. Elongated slots 440 are provided at corresponding positions on both the frame cover 410 and the plate cover 420. These slots allow both the mounting screw 240 and the second screw 230 on the same side to pass through simultaneously, while also restricting the position of the housing 400. The elongated slots 440 are located between the magnetic latch block 500 and the lock cylinder 600.

[0039] In this embodiment, the magnetic lock also includes a fixed locking block 800. A locking groove 810 is provided on one side of the fixed locking block 800. The size of the locking groove 810 is adapted to the size of the magnetic latch block 500, allowing the locking groove 810 to accommodate the insertion of one end of the magnetic latch block 500. A magnetic element 820 is installed on the bottom wall of the locking groove 810. The magnetic element 820 and the magnetic latch block 500 can attract each other, pulling one end of the magnetic latch block 500 into the locking groove 810. This magnetic lock can be used on framed or frameless doors and windows. When used on frameless glass doors and windows, the fixed locking block 800 and the mounting frame 200 are respectively installed on the corresponding mounting edges and door / window edges. When the glass door / window is closed, the magnetic latch block 500 is attracted by the magnetic element 820 and inserted into the locking groove 810, thereby achieving automatic locking of the door / window. Installation is convenient and the overall design is aesthetically pleasing and simple. Furthermore, this embodiment can also be applied to fixing parallel movable glass doors and fixed glass.

[0040] In other embodiments, the magnetic latch block 500 can also be embedded in a lock box, which is planar and has a locking groove 810 in the middle. The lock box can be installed on an aluminum frame door or wall with the mounting surface facing the side of the magnetic latch block 500 that protrudes.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
