Referring to fig. 1 to 2, several embodiments of the screw cover and the door lock of the present invention will be described.

As shown in fig. 1 to 2, an embodiment of the present invention provides a screw cover including a cover body 100 and a magnet 200. The outer end surface (i.e., the right end surface) of the magnet 200 is connected to the inner side surface (i.e., the left side surface) of the cover body 100. The cover 100 has a receiving groove, and the magnet 200 is disposed in the receiving groove and connected to a bottom surface of the receiving groove (i.e., an inner side surface of the cover 100).

Specifically, the magnet 200 and the lid 100 may be bonded by an adhesive, so that the magnet 200 is firmly fixed to the inner surface of the lid 100. With such a design, the cover 100 can be made of plastic, metal, etc.

In some embodiments, the magnet 200 is magnetically attracted to the cover 100. The lid 100 adopts ferromagnetic substance like iron to make, and when magnet 200 was placed in the holding tank of lid 100, magnet 200 was inhaled to lid 100 magnetism through magnetic force, need not to adopt adhesive or buckle structure, just can be fixed magnet 200 and lid 100 mutually fast, realized dismantling of magnet 200 and lid 100 in addition and be connected, the manufacturing process that makes the screw lid becomes very simple.

In some embodiments, the outer circumferential surface of the magnet 200 is connected to the inner circumferential wall surface of the cover 100. The size of magnet 200 just matches with the holding tank of lid 100, adopts the interference fit mode to install magnet 200 at the holding tank of lid 100, makes the outer peripheral face of magnet 200 and the laminating of the interior cliff side of lid 100 mutually, makes magnet 200 combine as an organic wholely with lid 100, avoids magnet 200 and lid 100 easy alternate segregation after the production equipment and leads to the screw lid product low in qualification rate.

In some embodiments, the inner side surface of the cover body 100 is provided with a slot, and an opening direction of the slot is the same as an opening direction of the receiving slot of the cover body 100 and faces to the left side of the cover body 100. The magnet 200 is arranged in the clamping groove, the shape of the clamping groove is matched with that of the magnet 200, and the outer peripheral surface of the magnet 200 is attached to the inner peripheral wall surface of the clamping groove. In addition, the clamping groove can be provided with a plurality of clamping claws, and the left end surface of the magnet 200 is firmly clamped by the clamping claws.

In this embodiment, the magnet 200 is a cylinder, and the cover 100 has a circular cross-sectional shape. Of course, the magnet 200 may have a square shape or other shape, and the cross-sectional shape of the cover 100 may also be square or other shape.

In addition, an embodiment of the present invention provides a door lock, which includes a screw 300, a first door lock 410, a second door lock 420, and a screw cover as described in the above embodiment.

The first door lock 410 is provided with a counter bore 411, the second door lock 420 is provided with a connecting hole 421, and the connecting hole 421 is provided with an internal thread. The screw 300 is made of a ferromagnetic material such as iron, and one end of the screw 300 with external threads can pass through the counter bore 411 to be connected with the connection hole 421, so that the first door lock 410 and the second door lock 420 can be installed on the inner side and the outer side of the door.

The screw lid is established in counter bore 411, and the screw lid is inhaled through magnet 200 and screw 300 magnetism for the screw lid is because of producing magnetic attraction with the screw 300 between, and makes the screw lid firmly install in counter bore 411, is difficult to drop, moreover, need not to adopt interference fit to install the screw lid, and the outer peripheral wall of screw lid and the inner peripheral wall of counter bore 411 can smooth connection, and guarantees that the clearance is less between the screw lid and the counter bore 411 of first lock 410.

The installation of the screw cover can provide better protection of the screw and decoration for the cover plate of the first door lock 410.

When the screw cover is disassembled, the bar-shaped magnet 500 with stronger magnetic force can be used, and the screw cover can be taken out according to the principle that magnets attract each other in opposite polarities, so that the screw cover is conveniently disassembled and assembled without other tools for damaging a door lock and the screw cover, and the reusability of the screw cover can be greatly improved.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
