Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

Example 1:

as shown in fig. 1 to 9, magnetism children safety lock, including lock shell 1, bottom plate 2, pivot 3, spring bolt 4, swing board 5 and magnetism subassembly 9 of inhaling, lock shell 1 block is on bottom plate 2, be fixed with two pivot supports 2a on bottom plate 2, pivot 3 is articulated to be installed on pivot support 2a, the middle part fixed connection of one end and pivot 3 of spring bolt 4, the other end can stretch out from the side of lock shell 1, the middle part fixed connection of the one end of swing board 5 and pivot 3, the other end have the cavity, have magnetic path A6 in this cavity is put, it has torsional spring 7 still to overlap in the pivot 3, the one end butt of torsional spring 7 is on the lower side surface of spring bolt 4, and the other end is fixed on the inner wall of lock shell 1, and when magnetism subassembly 9 is close to bottom plate 2, magnetic path A6 is repelled with magnetism subassembly 9 of inhaling. Will the utility model discloses a magnetism children safety lock installs on the inner wall of drawer, and under no external force effect, the torsion of torsional spring 7 makes spring bolt 4 outwards stretch out, and at this moment, spring bolt 4 can block on the fixture block of drawer panel downside, arranges the place that children can't contact in with magnetism subassembly 9. When the drawer needs to be opened, the bottom surface of the magnetic component 9 is close to the bottom plate 2, the magnetic block A6 is repelled with the magnetic component 9, the magnetic block A6 is repelled by the magnetic component 9, the swinging plate 5 swings upwards around the rotating shaft 3, meanwhile, the bolt 4 swings downwards around the rotating shaft 3, the part of the bolt 4 extending out of the lock case 1 rotates back into the lock case 1, and the drawer can be pulled at the moment, so that the drawer is opened.

Further, a torsion spring clamping seat 1a is arranged on the inner top surface of the lock case 1, and the tail end of the torsion spring 7 is fixed on the torsion spring clamping seat 1 a.

Further, the rotating shaft 3, the bolt 4 and the swinging plate 5 are of an integrated structure. The integral type structure can make the rotating part structure more stable, and the equipment degree of difficulty also reduces by a wide margin moreover.

Further, the magnetic assembly 9 includes a magnetic housing 9a and a magnetic block B9B, and the magnetic block B9B is clamped to the bottom of the magnetic housing 9 a. The magnetic block B9B is fixed in the magnetic casing 9a, so that the outward side of the magnetic block B9B is always the same magnetic pole, and the magnetic pole is the same as the magnetic pole of the magnetic block A6 facing the side of the bottom plate 2, when the magnetic casing 9a is directly held by hands to be close to the bottom plate 2, the magnetic block B9B and the magnetic block A6 can be mutually repelled, and the operation is simple and convenient.

Example 2:

on the basis of embodiment 1, a supporting plate 1c is arranged at the top of the lock case 1, slots 1b are formed in two sides of the supporting plate 1c, a through groove 1c1 is formed in the middle of the supporting plate 1c, and three grooves 1c2 are formed in the plate surface of the supporting plate 1 c. This structure is used to mount the switch assembly 8.

When the children grow up the back, when no longer needing magnetism children safety lock, in order to make the utility model discloses a magnetism children safety lock is inefficacy, in this embodiment, still includes switch module 8, switch module 8 includes plate body 8a, dog 8c and barb portion 8d, plate body 8 a's upper surface is equipped with portion 8b of gripping, plate body 8 a's lower surface middle part is equipped with dog 8c, plate body 8 a's lower surface both sides are equipped with barb portion 8d, be equipped with two parallel bead 8e on plate body 8 a's the lower surface, dog 8c passes in leading to groove 1c1 to extend the dorsal part of spring bolt 4, barb portion 8d passes from slot 1b of its homonymy to hook on the interior top surface of lock shell 1, two bead 8e cards are in adjacent two recess 1c 2. When magnetism children safety lock was effective, switch module 8 was located left position, and at this moment, dog 8c and the dorsal part of spring bolt 4 do not contact each other, did not influence the activity of spring bolt 4. When the magnetic child safety lock is no longer needed to work, the holding part 8b is pushed, the stop block 8c moves towards the right side, the bolt 4 rotates around the rotating shaft 3, the bolt 4 retracts into the lock shell 1, and meanwhile, the convex rib 8e on the lower surface of the plate body 8a is clamped in the groove 1c2 on the right position, so that the switch assembly 8 is positioned, the bolt 4 is always positioned in the lock shell 1, and the magnetic child safety lock is disabled.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
