Mini mechanical magnetic lock

Abstract

The invention discloses a miniature mechanical magnetic lock, which comprises a bracket (1) on one side of the door, a pull bolt (2) protruding vertically from the bracket (1), and a magnet (10) on the other side of the door, The sleeve (7) which is fixed on the magnet (10) and whose upper opening can be inserted into the pull bolt (2) and the stop ring (6) sleeved on the periphery of the sleeve (7). Wherein, the stop ring (6) is fixed in the iron plate (5) above the magnet (10) and can move axially relative to the sleeve (7), and one end of the limit connector (3) is fixed on the magnet (10), The other end is inserted into an opening at a corresponding position on the iron plate (5), and the limit connector 3 is covered with a spring (4) so ​​that the magnet (10) and the iron plate (5) are mutually biased. This mechanical magnetic lock structure can further reduce the volume of the product. The arrangement of the spring matches the shape and structure of the iron plate and the magnet to further reduce the volume of the product, and the structure on the side of the pull bolt bracket is simpler and smaller.

Description

Technical field [0001] The invention relates to a magnetic lock, in particular to a mini-type mechanical magnetic lock. Background technique [0002] An existing small magnetic mechanical door lock structure such as figure 1 As shown, a protruding bat 2 is provided on the base plate 1 of one of the two opposing door panels, an iron plate 12 is provided on both sides of the protruding bat 2, and a cylindrical ball receiving cavity is provided on the other door panel. 7 and an axially movable stop ring 6 sleeved on the periphery of the spherical cavity 7. Wherein, the protruding ball 2 is a cylindrical rod with a ball at one end of the protrusion perpendicular to the door. The diameter of the ball at the end of the protruding ball 2 is larger than the diameter of the cylinder, on the stop ring 6, at a position corresponding to the iron plate 12. Set the magnet 10. The existing magnetic mechanical door lock realizes the conversion of a small electromagnetic force to achieve a larg...

Problems solved by technology

[0003] The volume of this existing small mechanical magnetic lock has a lower limit. The smaller the product volume, the smaller the magnetic surface, and the smaller the magnetic surface, the smaller the magnetic force. Therefore, the product that needs to be locked if the volume is too small cannot be locked.
