All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a child lock cover, which includes an inner cover 1, an inner ring 2 and an outer cover (not labeled in the figures), wherein the inner ring 2 and the outer cover are sleeved on the inner cover 1 and form a rotational connection, the inner cover 1 and the inner ring 2 are assembled and then installed in the outer cover, and the inner ring 2 and the outer cover are assembled and connected; the inner cover 1 comprises a first top wall 12 and a first side wall 11 formed by bending and extending the outer periphery of the first top wall 12, a plurality of limiting blocks 13 are formed by protruding one side of the first top wall 12 close to the inner ring 2, and the limiting blocks 13 are arranged at intervals; the inner side of the first side wall 11 is provided with an internal thread 3; the inner ring 2 comprises a second top wall 22 and a second side wall 21 extending from the outer periphery of the second top wall 22 in a bending mode, one side, close to the inner cover 1, of the second top wall 22 protrudes to form a plurality of clamping blocks 23 which are spaced from each other and matched with the limiting blocks 13, the limiting blocks 13 and the clamping blocks 23 are spaced from each other in the axial direction of the inner ring 2, and each clamping block 23 is clamped between two adjacent limiting blocks 13 when pressure is applied to the inner ring 2 in the axial direction towards the inner cover 1.
Each clamping block 23 on the inner ring 2 moves downwards to a position between two adjacent limiting blocks of the inner cover 1 by pressing the inner ring 2, the inner ring 2 is kept pressed and simultaneously rotated, and the applied rotating force is transmitted to the limiting blocks 13 by the clamping blocks 23, so that the inner cover 1 is driven to rotate, and the cover is rotated and unscrewed; when the child lock is used, the inner ring 2 is not pressed, the clamping blocks 23 and the limiting blocks 13 are spaced along the axial direction of the inner ring 2, the friction force between the inner ring 2 and the inner cover 1 is far smaller than the meshing force between the internal thread 3 of the inner cover 1 and the matched external thread, the inner ring 2 rotates, and the inner ring 2 only idles relative to the inner cover 1, so that the child lock function is realized.
When the cover is opened, the limiting block 13 and the latch 23 are locked by applying downward pressure and then rotate, so that the cover can be opened. When no force is applied, the clamping block 23 and the limiting block 13 are separated, and the child only knows to rotate the cap and does not know to apply downward pressure, at the moment, the rotation is an idle rotation inner ring, and the inner cap 1 cannot move, so that the child lock function is realized. After the pressure of the inner cover 1 is removed, the limiting block 13 can be automatically reset upwards to be separated from the clamping block 23, and therefore, the inner ring 2 needs to be made of elastic materials to be deformed and reset, such as plastics.
The internal thread 3 is intended to cooperate with an external thread of a mating box opening or spout to form a threaded connection. The inner cover 1 is used for covering the box or the pipe barrel structure, an external thread is arranged on the outer side of one end of the box or the pipe barrel structure, and the internal thread is used for forming threaded connection with the external thread, so that the inner cover 1 is covered on the box or the pipe barrel.
The limiting blocks 13 are uniformly arranged along the circumferential direction of the first top wall 11; the plurality of latch blocks 23 are uniformly arranged along the circumferential direction of the second top wall 22.
An avoidance hole 24 is formed in the center of the second top wall 22.
The inner ring 2 further includes an annular support wall 25 formed by bending an end of the second side wall 21 away from the second top wall 22 inward, and an end of the first side wall 11 away from the first top wall 12 is supported on the support wall 25.
The width of the support wall 25 is equal to the thickness of the first side wall 11
The clamping block 23 and the limiting block 13 are rectangular structures.
The outer diameter of the inner cover 1 is smaller than the inner diameter of the inner ring 2. The function of the child lock is realized by sleeving the inner ring 2 on the inner cover 1 conveniently.
The utility model specifically uses the principle:
during the use, need press inner circle 2 downwards for each fixture block 23 on the inner circle 2 moves down to between two adjacent spacing of inner cup 1 soon, keeps pressing and rotates inner circle 2 simultaneously, and the revolving force of applying is transmitted to stopper 13 by fixture block 23, thereby drives inner cup 1 rotatory, thereby realizes that the rotation of lid is unscrewed.
When the child lock is used, the inner ring 2 is not pressed (pressure is applied through the outer cover), the fixture blocks 23 and the limiting blocks 13 are spaced along the axial direction of the inner ring 2, the friction force between the inner ring 2 and the inner cover 1 is far smaller than the meshing force between the internal thread 3 of the inner cover 1 and the matched external thread, at the moment, the inner ring 2 is rotated, and the inner ring 2 only idles relative to the inner cover 1, so that the child lock function is realized.
When not pressing, the fixture block 23 and the limiting block 13 are separated through the outer diameter of the inner cover 1 and the inner diameter difference design of the inner ring 2, and the pressing limiting is realized through the elastic deformation of the inner ring 2.
The utility model also provides a packaging box comprising the child lock cover.
Compared with the prior art, in the child lock cover and the packing box, the inner cover 1 and the inner ring 2 are assembled and then installed in the outer cover, and the inner ring 2 is assembled and connected with the outer cover; the inner cover 1 comprises a first top wall 12 and a first side wall 11 formed by bending and extending the outer periphery of the first top wall 12, a plurality of limiting blocks 13 are formed by protruding one side of the first top wall 12 close to the inner ring 2, and the limiting blocks 13 are arranged at intervals; the inner side of the first side wall 11 is provided with an internal thread 3; the inner ring 2 comprises a second top wall 22 and a second side wall 21 extending from the outer periphery of the second top wall 22 in a bending mode, one side, close to the inner cover 1, of the second top wall 22 protrudes to form a plurality of clamping blocks 23 which are spaced from each other and matched with the limiting blocks 13, the limiting blocks 13 and the clamping blocks 23 are spaced from each other in the axial direction of the inner ring 2, and each clamping block 23 is clamped between two adjacent limiting blocks 13 when pressure is applied to the inner ring 2 in the axial direction towards the inner cover 1. In the structure, each clamping block 23 on the inner ring 2 moves downwards to a position between two adjacent limiting blocks of the inner cover 1 by pressing the inner ring 2, the inner ring 2 is kept pressed and simultaneously rotated, and the applied rotating force is transmitted to the limiting blocks 13 by the clamping blocks 23, so that the inner cover 1 is driven to rotate, and the cover is rotated and unscrewed; when the child lock is used, the inner ring 2 is not pressed, the clamping blocks 23 and the limiting blocks 13 are spaced along the axial direction of the inner ring 2, the friction force between the inner ring 2 and the inner cover 1 is far smaller than the meshing force between the internal thread 3 of the inner cover 1 and the matched external thread, the inner ring 2 rotates, and the inner ring 2 only idles relative to the inner cover 1, so that the child lock function is realized.
