Abstract

The utility model discloses a magnetic lock head which is characterized in that a magnetic marble is arranged in the lock head. The surface of the lock head does not need to be provided with a keyhole. When the lock head is opened, a traditional key is not needed. A small magnetic bar is used for striking on the marking part of the blind plate of the lock head, and the lock head can be opened or be closed. The magnetic lock head has the advantage that the phenomenon that a key is easily blocked can be avoided. Simultaneously the safe performance of the lock is increased.

Description

Magnetic lock head

The utility model belongs to the padlock technical field, is specifically related to the improvement at latch lock core position.

The core position of latch is lock core, is commonly called as tapered end.The basic comprising of existing tapered end is to install pellet shot from a slingshot additional in the inner bullet groove of tapered end, and the open-type locking of lock is to realize by the position of extrapolation key adjusting pellet shot from a slingshot.In order to inject key, must offer keyhole on the existing tapered end, the problem that the tapered end that this keyhole exposes exists is to stop up foreign matter easily, is also lost anti-general effect by the people by the keyhole forged key easily in addition.

The purpose of this utility model is that by changing the structure of tapered end, the cancellation keyhole is to increase the security reliability of lock.

The utility model has been taked the technical scheme shown in accompanying drawing 1 for achieving the above object, the tapered end main body is formed by lock holder 1 and lock tube 2 movable sets, on lock holder 1 and lock tube 2, offer blind hole bullet groove more than two pairs accordingly, in every pair of bullet groove, place a magnetic bullet, the placement direction of pellet shot from a slingshot will guarantee that NS is extremely interlaced, the external surface of lock holder 1 is a blind plate, is carved with mark on the corresponding position of bullet groove inner with it, blind plate surface, and the other end of lock holder 1 is installed plectrum 3 by collar.

Effect of the present utility model: cancelled the keyhole that traditional tapered end exposes, only need rely on the mark striking of little magnetic bar to reach during unlatching and open and the locking purpose, not only avoid the foreign matter clogging but also increased the security insurance performance of lock on the tapered end surface.

Fig. 1 is the utility model section of structure.Wherein 1 for lock holder, 2 be lock tube, 3 for plectrum, 4 and 4 for bullet groove, 5 for magnetic bullet, 6 for magnetic bullet, 7 and 7 for bullet groove, 8 for pellet shot from a slingshot part mark, 9 be collar.
