[ detailed description ] embodiments

The invention is described in further detail below with reference to the following figures and detailed description:

as shown in fig. 1 to 18, a nanny lock capable of switching use states comprises a lock core, a main key 71 and a nanny key 72, wherein the main key 71 and the nanny key 72 are matched with the lock core, the lock core comprises a lock shell 1, a dial puller 2 arranged in an open slot in the middle of the lock shell 1, an outer lock liner 3 and an inner lock liner 4 which are arranged in the lock shell 1 and positioned at two sides of the dial puller 2, the lock shell 1 and the outer lock liner 3 are matched with each other through N groups of marble components 5 distributed along a key insertion direction, N marble holes 31 corresponding to the marble components 5 one to one are arranged in the outer lock liner 3, N first flat ball holes 11 corresponding to the marble components 5 one to one and N second flat ball holes 12 corresponding to the marble components 5 one to one are arranged in the lock shell 1, and each group of the marble components 5 comprises a marble 51 arranged in the marble holes 31, a first flat ball return spring 52 and a first flat ball return spring 53 arranged in the first flat ball hole 11, and a second flat ball return spring 12 arranged in the second flat ball hole 12 Second flat ball 54 and second flat ball return spring 55; the axis of the first flat ball hole 11 and the axis of the second flat ball hole 12 matched with the same group of marble components 5 are on the same cross section, and the included angle between the two axes is alpha degrees; the lock shell 1 is also internally provided with a conversion ring 6 sleeved on the outer lock cylinder 3, the conversion ring 6 is provided with at least one conversion hole 60 aligned with the marble hole 31, a plurality of groups of marble components 5 are provided with at least one group of marble components 5 matched with the conversion hole 60, the rest groups of marble components 5 are provided with at least one group of marble components 5 also matched with a second flat bead 54, N is a positive integer;

when the marble hole 31, the conversion hole 60 and the first flat pearl hole 11 are aligned, the lock cylinder is in a non-nanny unlocking state, the lock cylinder can be unlocked by inserting the main key 71 in a rotating way, and can not be unlocked by inserting the nanny key 72 in a rotating way; when the ball hole 31, the conversion hole 60 and the second flat ball hole 12 are aligned, the lock cylinder is in a nanny-openable state, and the lock cylinder can be rotated and unlocked by inserting the main key 71 or the nanny key 72. Can drive the switching circle through the master key and rotate and switch marble and first flat pearl or the cooperation of the flat pearl of second and then switch tool to lock state control nanny and whether unblank, can control nanny live time, worry problem when also can solving change nanny, the security is high.

In this embodiment, the lock case 1 is provided with an outer lock cylinder hole 13 for accommodating the outer lock cylinder 3, and a switching groove 10 for accommodating the switching ring 6 is formed in the inner wall of the outer lock cylinder hole 13, so that the structure space is compact. Of course, the outer peripheral surface of the outer lock container hole 13 may be provided with a groove for mounting the change-over ring 6.

In this embodiment, the axis of the first flat bead hole 11 and the axis of the second flat bead hole 12 intersect on the rotation center line of the outer lock core 3, so that the outer lock core 3 can ensure that the ball hole 31 can be aligned with the first flat bead hole 11 or the second flat bead hole 12 when rotating. In this embodiment, the axis of the first flat ball hole 11 and the axis of the second flat ball hole 12 are on the same cross section and the included angle therebetween is α °, and α ° may be any angle in the case that the size of the lock case 1 is sufficient for installing the ball assembly 5, such as a lock case with a larger size and a wider width. In the present embodiment, the lock case is smaller in size, and there is enough space for the ball assembly 5 to be installed at the upper ends of the outer and

inner lock cores

3 and 4, so that α is 30 ± 5, whereas α ° is 30 ° in the drawing.

In the present embodiment, the primary key 71 is prevented from being removed by a family (especially, the elderly and children) when the family is not rotated to a proper position (the marble hole 31 is misaligned with the first flat bead hole 11), so that the nanny lock further comprises a secondary key 73, when the nanny key 72 is inserted, the lower end of the first flat bead 52 or the lower end of the second flat bead 54 is inserted into the conversion hole 60 so that the conversion ring 6 cannot rotate together with the outer lock cylinder 3; when the lock cylinder is in a non-nanny-unlocked state or in a nanny-unlocked state, the secondary key 73 can be rotated to unlock, but the state of the nanny-lock cannot be switched.

In this embodiment, the lock case 1 and the inner lock core 4 may be linked by other ways without inserting a key, such as a knob structure disclosed in the unlocking and configuration control method of a key-insertion type smart lock with a unique identity authentication ID disclosed in chinese patent publication No. CN110094113B by the applicant. The lock shell 1 and the inner lock liner 4 are matched through a plurality of groups of marble assemblies 5 distributed along the key insertion direction, and are locked through a key. The distribution of the marble assemblies 5 arranged between the lock shell 1 and the inner lock liner 4 and the distribution of the marble assemblies 5 arranged between the lock shell 1 and the outer lock liner 3 along the key insertion direction are the same. The lock shell 1 is also internally provided with the conversion ring 6 sleeved on the inner lock liner 4, the lock shell 1 is provided with an inner lock liner hole 14 used for containing the inner lock liner 4, and the inner wall of the inner lock liner hole 14 is inwards concave to form a conversion groove 10 used for containing the conversion ring 6. Because the front teeth of the main key 71 are the same as the back teeth thereof, the front teeth of the nanny key 72 are the same as the back teeth thereof, the front teeth of the auxiliary key 73 are the same as the back teeth thereof, and the structure between the lock case 1 and the inner cylinder 4 is the same as the structure between the lock case 1 and the outer cylinder 3 for the convenience of the user.
