Description

Technical Field:

[0001] The utility model relates to the field of magnetic locks, in particular to a magnetic lock handle idle rotation structure. Background Art:

[0002] With the continuous improvement of the material living standard, people's requirements for locks are also getting higher and higher. At present, the locks on the market generally rely on magnetic attraction to realize the engagement of the lock tongue and the buckle box.

[0003] Chinese Patent Document CN107724802A discloses a silent magnetic lock body on February 23, 2018. As recorded in this patent, as Figure 1 shown, after the door is closed, the tongue magnet in the tongue assembly attracts the buckle magnet in the buckle box assembly. The tongue piece rotates around the fixed axis and extends out, and is buckled into the buckle box to lock the door. When buckling, the tongue piece contacts the sound insulation board to avoid generating collision noise. At this time, the tongue dial head leaves the square tongue locking convex block and can slide in the dial block working groove, releasing the locking of the square tongue assembly, and the square tongue can extend out. As Figure 2 shown, when it is necessary to lock the door again after closing the door, the square tongue is pulled out. The anti-lock convex block on the square tongue plate approaches the lower end of the tongue piece and presses against the anti-lock block, so that the tongue piece cannot rotate around the positioning axis, and the tongue box cannot be retracted, achieving the purpose of locking the tongue piece.

[0004] This patent has the following problems. When locking the door again after closing the door, the tongue piece rotates around the fixed axis and extends out. The anti-lock convex block on the square tongue plate approaches the lower end of the tongue piece and presses against the anti-lock block, making the tongue piece unable to rotate. In the anti-lock state, the square core dial component cannot push the tongue piece to rotate but can apply pressure to the tongue piece. In the process of using this structure, because users are not sure whether to lock the door again, they often apply too much pressure to the square core dial component inside the handle, and the internal structural components are prone to damage or deformation, resulting in a short service life. Content of the Utility Model:

[0028] Such as Figures 3 to 6As shown in the figure, this embodiment provides a magnetic lock handle idling structure, which includes a housing 1, a square core dial component 2, a locking tongue component 3, an unlocking lever 4, a locking piece 5 and a lock core dial 6. A through first through hole 101 and a second through hole 102 are provided on the housing 1. The square core dial component 2 is located in the first through hole 101, and the square core extends into the square core dial component 2 to rotate. The lock core dial 6 is located in the second through hole 102, and the lock core is inserted into the second through hole. A torsion spring 21 is sleeved on the square core dial component 2. The torsion spring 21 is used to make the square core dial component 2 return to its original position after rotation. The locking piece 5 is located on one side of the lock core dial 6, and the locking piece 5 is pushed to move up and down by the rotation of the lock core dial 6. The locking tongue component 3 and the unlocking lever 4 are hinged inside the housing. The end of the locking piece 5 is provided with a first boss 51 and a second boss 52. When the locking piece 5 moves upward, the unlocking lever 4 is pushed to rotate by the first boss 51. The unlocking lever 4 pushes the locking tongue component 3 to rotate so that the locking tongue component 3 extends and retracts inside and outside the housing 1. A dial piece 22 extends from the square core dial component 2. The second boss 52 of the locking piece 5 is located at the top of the locking piece 5, and a relief opening 501 for cooperating with the dial piece 22 is left on one side of the second boss 52. When the locking piece 5 moves to the bottom, the locking tongue component 3 is attracted by magnetic force and extends into the buckle box for anti-locking. The relief opening of the second boss 52 of the locking piece 5 is far away from the dial piece 22 of the square core dial component 2. After locking, the square core dial component 2 is in an idling state, and will not apply pressure to the components inside the magnetic lock, avoiding damage or deformation and improving the service life.

[0029] As an optional embodiment, the square core dial component 2 includes a square core dial 23 and a rotating dial plate 24. The square core dial 23 is for conveniently sleeved into the rotating dial plate 24. A third through hole 241 is provided in the middle of the rotating dial plate 24. The square core dial 23 is located in the third through hole 241.

[0030] As an optional embodiment, a first cylinder 11 is provided inside the housing 1. The first cylinder 11 is located on one side of the square core dial component 2. One end of the torsion spring 21 is restricted on the first cylinder 11. A second cylinder 242 is provided on the periphery of the rotating dial plate 24. The other end of the torsion spring 21 is restricted on the second cylinder 242.

[0031] As an optional embodiment, a limit block 243 extends from one side of the rotating dial plate 24. When the square core dial component 2 rotates clockwise, the limit block 243 abuts against the first cylinder 11 to control the rotation range of the square core dial component 2.

[0032] As an alternative embodiment, a hinge post 31 is provided at the middle position of the latch assembly 3. The latch assembly 3 is hinged to the housing 1 through the hinge post 31. The unlocking lever 4 pushes the lower part of the latch assembly 3 to make the latch assembly 3 rotate clockwise. This way can reduce the pushing distance and the pushing range is shorter.

[0033] As an alternative embodiment, a first protrusion 61 is provided on the lock core cam 6, and a notch 502 cooperating with the first protrusion 61 is provided on the locking member 5. The first protrusion 61 is inserted into the notch 502, and then the lock core cam 6 is rotated to push the locking member 5 to move up and down.

[0034] As Figure 7 shown, when closing the door, the lock core cam 6 rotates counterclockwise. Through the first protrusion 61 of the lock core cam 6, the locking member 5 is in the lowest state. The first boss 51 of the locking member 5 is far away from the unlocking lever 4. The unlocking lever 4 and the latch assembly 3 are in a freely rotatable state. During the process of closing the door, the latch assembly 3 is affected by the magnetic force of the buckle box, so that the latch assembly 3 extends out of the housing and enters the buckle box. When the handle rotates the square core cam assembly 2, the dial 22 of the square core cam assembly 2 cannot contact the locking member 5 because the locking member 5 is in the lowest state. The locking member 5 also has an avoidance opening 501 reserved. Therefore, this structure can achieve the state of free rotation of the square core cam assembly 2 after the magnetic lock is locked, and will not damage or deform the internal components of the magnetic lock, thus improving the service life.

[0035] As Figure 8 shown, when unlocking is needed, the lock core cam 6 rotates clockwise to lift the locking member 5. When the first boss 51 of the locking member 5 is higher than the dial 22 of the square core cam assembly 2, the dial 22 on the square core cam assembly 2 is rotated to lift the first boss 51. The second boss 52 of the locking member 5 moves upward to push the unlocking lever 4, and the unlocking lever 4 pushes the latch assembly 3 to rotate clockwise along the hinge post 31 to achieve the unlocking effect.

[0036] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are equivalent replacement methods and are all included in the protection scope of the present invention.
