Rotating the upper rotating part 1-4 clockwise to drive the main shifting part 1-4-1 arranged on the upper rotating part 1-4 to rotate, shifting the secondary shifting part 1-9-1 on the middle rotating part 1-9 to form the middle rotating part 1-9 to rotate anticlockwise, shifting the hook teeth 1-5-3 arranged on the lock tongue 1-5 by the unlocking part 1-9-2 arranged on the middle rotating part 1-9 to form the lock tongue 1-5 to rotate clockwise, changing the straight line anticlockwise direction from the first positioning column 1-5-2, the rotating hole 1-5-1 and the second positioning column 1-1-1 to the clockwise direction, and changing the straight line anticlockwise direction from the three-ring spring 1-6 to the lock tongue 1-5 to the clockwise direction, the lock tongues 1-5 stay, position, open the door, unclamp the handle, the upper rotating member 1-4 resets under the influence of second reset spring 1-7, the middle rotating member 1-9 resets under the influence of first reset spring 1-10, in this movement, the handle rotates and drives the upper rotating member 1-4 to rotate, the upper rotating member 1-4 drives the middle rotating member 1-9, the middle rotating member 1-9 drives the lock tongues 1-5, form the connected rotation, make the lock tongues 1-5 return, the door can be opened.
The spring bolt 1-5 is popped up to be in a door locking state, the spring bolt 1-5 returns to be in a door opening state, under the state that the spring bolt 1-5 returns, the lower rotating piece 1-11 is driven to rotate anticlockwise through rotating the counter lock knob, the middle rotating piece 1-9 is driven to rotate clockwise, the teeth of the locking hook 1-9-4 arranged on the middle rotating piece 1-9 are combined with the teeth of the hook teeth 1-5-3 arranged on the spring bolt 1-5 to form a propping effect, and the spring bolt 1-5 cannot be popped up under the action of a magnet when the door is closed. The arrangement of the structure prevents a person from rotating the back locking knob under the condition of no intention to cause automatic locking after the door is closed, certainly, the person does not need to lock when the door is not closed, the back locking knob can be rotated anticlockwise in advance, and the door can not be locked when the door is closed.
The pinch plate is provided with a front sliding piece and a rear sliding piece 2-2, when the door leaf is gasped forwards and backwards after the door is closed, namely the door leaf is rocked forwards and backwards, the upper screw and the lower screw are loosened, and the front sliding piece and the rear sliding piece 2-2 are moved forwards and backwards, so that the problem of gasping the door leaf forwards and backwards is solved. The effect of setting up this piece lies in, the combination after buckle hole site and the door leaf are closed during carpenter's installation often forms the door leaf and wheys or wheys around, and some doors are installed even, or form the wheys or wheys after a section is used, and the sound from beginning to end gives people and causes unnecessary trouble.
The magnetic silent lock provided by the invention has the advantages that the starting force of rotation is applied to the lock tongues 1-5 through magnetic force, the stress of the three-coil springs 1-6 is changed through the rotation of the lock tongues 1-5, the clockwise force is changed into the anticlockwise force, and the lock tongues 1-5 are ejected. The magnetic silent lock provided by the invention has the advantages of simple structure, stable locking and capability of ensuring the service life of the lock body.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
