Description

Technical Field

[0001] This utility model belongs to the field of magnetic locks and relates to a simple magnetic lock. Background Technology

[0002] Traditional magnetic locks have complex structures with numerous internal components, making installation difficult. The large number of components also increases production costs and makes the structure more prone to instability. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a simple magnetic lock. This device has the advantages of simple structure and few parts, yet it can still achieve both unlocking and locking functions.

[0004] The objective of this invention is achieved as follows:

[0005] A simple magnetic lock includes a lock shell, a magnetic latch inside the lock shell, a latch hole formed at the front end of the lock shell for the magnetic latch to extend out, a latch plate connected to the rear end of the magnetic latch, a lever plate rotatably disposed inside the lock shell, the lever plate having a square core hole inside, and a pull plate that can slide up and down inside the lock shell. A guide slope is formed on the latch plate, and a guide protrusion is provided on the pull plate corresponding to the guide slope. When the pull plate moves up, the guide protrusion pushes against the guide slope, causing the latch plate to drive the magnetic latch to retract into the lock shell.

[0006] The middle part of the pull plate is also formed with a toggle lug, and the toggle plate extends to the toggle lug with a toggle end;

[0007] The lower end of the pull plate is provided with a deadbolt lug, and the lock housing is provided with a lock cylinder on the side corresponding to the deadbolt lug.

[0008] In the unlocked state, the actuating end is located below the actuating lug. In the deadbolt state, the lock cylinder rotates and moves the pull plate down through the deadbolt lug, so that the actuating lug of the pull plate is located on the side of the actuating end and blocks the actuating end.

[0009] This invention, through the above-described configuration, allows for unlocking by turning the handle. The handle's square core rotates the actuating plate, causing the actuating end of the actuating plate to move the pull plate upwards. The guide protrusion of the pull plate moves upwards, causing the bolt plate and magnetic bolt to retract into the lock housing, thus unlocking. For deadbolt locking, the lock cylinder rotates, causing the pull plate to move downwards via the deadbolt lug. This positions the pull plate's actuating lug on the side of the actuating end, blocking it and preventing the actuating end from moving the pull plate upwards, thus achieving deadbolt locking. This invention only requires a magnetic bolt, bolt plate, actuating plate, pull plate, and lock cylinder within the lock housing to achieve both unlocking and deadbolt functions. The structure is simple, with fewer parts, improving structural stability, facilitating installation, and reducing costs.

[0010] The invention is further configured such that the lower end of the guide slope is farther away from the magnetic latch than the upper end, and the guide protrusion is located below the guide slope.

[0011] The present invention is further configured such that: a guide block is formed at the upper end of the pull plate, and a vertical pull plate guide groove is formed on the lock shell, and the guide block is slidably disposed in the pull plate guide groove.

[0012] By setting up guide blocks and guide grooves for the pull plate, the vertical movement of the pull plate can be guided, and the two ends of the guide grooves can also serve as limiters.

[0013] The invention is further configured such that: the lower end of the pull plate is formed with a vertical guide groove, and the lock housing is provided with a guide lug corresponding to the guide groove, the guide lug being disposed in the guide groove.

[0014] The guide groove and guide lugs not only guide the vertical movement of the pull plate, but also provide limiting functions at both ends of the guide groove. Together with the pull plate guide groove and guide block, they achieve simultaneous guiding and limiting functions on both the upper and lower sides, resulting in better guiding and limiting effects.

[0015] The present invention is further configured such that: a reset lug is also formed on the pull plate, and the reset lug is disposed below the toggle end.

[0016] The reset lug design allows the lever to be pushed down by rotating the handle in the opposite direction or by the action of the torsion spring, returning the lever to its pre-unlock state for easy unlocking next time.

[0017] The present invention is further configured such that the actuating end is disposed between the reset lug and the actuating lug.

[0018] With the above settings, the pull plate can be moved up by rotating the toggle end in the forward direction, and the pull plate can be reset by rotating the toggle end in the reverse direction.

[0019] The invention is further configured such that: the lock housing is provided with a torsion spring corresponding to the actuating plate, the torsion spring abuts against the side of the actuating plate away from the magnetic latch, and the torsion spring always provides a force to the actuating end of the actuating plate to drive the reset lug to move downward.

[0020] The present invention is further configured such that: the upper end of the toggle plate is formed with a limiting groove, and the lock housing is provided with a limiting post corresponding to the limiting groove, the limiting post being disposed within the limiting groove.

[0021] The design of the limiting groove and limiting post can limit the range of rotation of the toggle plate, making it more convenient to use.

[0022] The present invention is further configured such that: a transverse groove is formed on the locking tongue plate, and a limiting post is disposed in the transverse groove.

[0023] The horizontal grooves limit the range of movement of the latch plate, making it more convenient to use.

[0024] The invention is further configured such that: a positioning spring is fixed on the pull plate, the positioning spring is provided with a positioning protrusion, and two positioning holes are formed on the lock shell, namely a reverse locking positioning hole and a normal positioning hole. In the normal state, the positioning protrusion is set in the normal positioning hole, and in the reverse locking state, the positioning protrusion moves into the reverse locking positioning hole.

[0025] The positioning spring mechanism allows users to clearly see whether the lock is properly engaged or unlocked, making it more convenient to use.

[0026] The significant and beneficial technical effects of this invention compared to existing technologies are as follows: When unlocking is required, turning the handle causes the handle's square core to rotate the actuating plate. The actuating end of the actuating plate moves the pull plate upward, and the guide protrusion of the pull plate moves upward, causing the bolt plate and magnetic bolt to retract into the lock case, thus unlocking. When deadbolting is required, the lock cylinder rotates, causing the pull plate to move downward through the deadbolting lug. This allows the actuating lug of the pull plate to be positioned on the side of the actuating end and block the actuating end, preventing the actuating end from moving the pull plate upward, thereby achieving deadbolting. This invention only requires a magnetic bolt, bolt plate, actuating plate, pull plate, and lock cylinder within the lock case to achieve both unlocking and deadbolting functions. The structure is simple, with fewer parts, improving structural stability, facilitating installation, and reducing costs. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] A simple magnetic lock includes a lock shell 1, a magnetic latch 2 inside the lock shell 1, a latch hole 3 formed at the front end of the lock shell 1 for the magnetic latch 2 to extend out, a latch plate 4 connected to the rear end of the magnetic latch 2, a lever plate 5 rotatably arranged inside the lock shell, a square core hole 6 inside the lever plate 5, a pull plate 7 that can slide up and down inside the lock shell 1, a guide slope 8 formed on the latch plate 4, a guide protrusion 9 corresponding to the guide slope 8 on the pull plate 7, when the pull plate 7 moves up, the guide protrusion 9 pushes against the guide slope 8, causing the latch plate 4 to drive the magnetic latch 2 to retract into the lock shell;

[0040] The middle part of the pull plate 7 is also formed with a toggle lug 10, and the toggle plate 5 extends to the toggle lug 10 to form a toggle end 11.

[0041] The lower end of the pull plate 7 is provided with a deadbolt lug 12, and the lock shell is provided with a lock cylinder 13 on the side corresponding to the deadbolt lug;

[0042] In the unlocked state, the actuating end 11 is located below the actuating lug 10. In the deadbolt state, the lock cylinder 13 rotates and moves the pull plate 7 downward through the deadbolt lug 12, so that the actuating lug 10 of the pull plate is located on the side of the actuating end 11 and blocks the actuating end 11.

[0043] The lower end of the guide slope 8 is farther away from the magnetic latch 2 than the upper end, and the guide protrusion 9 is located below the guide slope.

[0044] The upper end of the pull plate 7 is formed with a guide block 14, and the lock housing 1 is formed with a vertical pull plate guide groove 15. The guide block 14 is slidably disposed in the pull plate guide groove 15. The guide block 14 and the pull plate guide groove 15 can guide the vertical movement of the pull plate 7, and the two ends of the pull plate guide groove 15 can also play a limiting role.

[0045] The lower end of the pull plate 7 is formed with a vertical guide groove 16, and the lock housing 1 is provided with a guide lug 17 corresponding to the guide groove 16, with the guide lug 17 disposed within the guide groove 16. Through the function of the guide groove 16 and the guide lug 17, not only can the vertical movement of the pull plate 7 be guided, but the two ends of the guide groove 16 can also serve as limiting points. Together with the pull plate guide groove 15 and the guide block 14, they can achieve simultaneous guiding and limiting functions on both the upper and lower sides, resulting in better guiding and limiting effects.

[0046] The pull plate 7 is also formed with a reset lug 18, which is located below the toggle end 11. Through the design of the reset lug 18, when the handle is rotated in the opposite direction or under the action of the torsion spring, the toggle end 11 can push the reset lug 18 down, so that the pull plate 7 moves down to the state before unlocking, making it convenient to open next time.

[0047] The actuating end 11 is disposed between the reset lug 18 and the actuating lug 10. With the above arrangement, the pull plate 7 can be moved upward by rotating the actuating end 11 in the forward direction, and the pull plate 7 can be moved downward and reset by rotating the actuating end 11 in the reverse direction.

[0048] The lock case 1 is also provided with a torsion spring 19 corresponding to the actuating plate 5. The torsion spring 19 abuts against the side of the actuating plate 5 away from the magnetic latch 2. The torsion spring 19 always provides a force to the actuating end 11 of the actuating plate 5 to drive the reset lug 18 to move downward.

[0049] The upper end of the actuating plate 5 is formed with a limiting groove 20, and the lock housing is provided with a limiting post 21 corresponding to the limiting groove 20. The limiting post 21 is disposed within the limiting groove 20. The design of the limiting groove 20 and the limiting post 21 can limit the range of rotation of the actuating plate 5, making it more convenient to use.

[0050] The latch plate 4 has a transverse groove 22 formed on it, and the limiting post 21 is disposed in the transverse groove 22. The transverse groove 22 restricts the range of movement of the latch plate 4, making it more convenient to use.

[0051] A positioning spring 23 is also fixed on the pull plate 7. The positioning spring 23 has a positioning protrusion 24. The lock housing has two positioning holes: a reverse locking positioning hole 25 and a normal positioning hole 26. In the normal state, the positioning protrusion 24 is located in the normal positioning hole 26. In the reverse locking state, the positioning protrusion 24 moves into the reverse locking positioning hole 25. The positioning spring 23 allows the user to clearly know whether the lock is properly engaged or unlocked, making it more convenient to use.

[0052] Working principle of the invention:

[0053] When unlocking is required, the handle is turned, and the square core of the handle drives the actuating plate 5 to rotate. The actuating end 11 of the actuating plate drives the pull plate 7 to move upward. The guide protrusion 9 of the pull plate 7 moves upward, causing the bolt plate 4 and the magnetic bolt 2 to retract into the lock case 1, thus unlocking. After unlocking, the handle is released, and the actuating plate 5 returns to its original position under the action of the torsion spring 19, causing the limiting groove 20 to move away from the groove wall of the magnetic bolt and abut against the limiting post 21. When the actuating plate 5 returns to its original position, the actuating end 11 drives the return lug 18 to move downward, thereby causing the pull plate 7 to move downward, so that the pull plate 7 also returns to its normal position. In the normal position, the positioning protrusion 24 of the positioning spring 23 is set in the normal positioning hole 25.

[0054] When deadbolt is required, the lock cylinder 13 rotates and moves the pull plate 7 downward through the deadbolt lug 12, so that the pull plate's actuating lug 10 is positioned on the side of the actuating end 11 and blocks the actuating end 11. The actuating end 11 cannot drive the pull plate 7 upward, thereby achieving deadbolt.

[0055] This invention features a simple structure and few parts, yet still achieves both unlocking and locking functions.

[0056] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
