Abstract

The utility model relates to a magnetic key. The utility model is realized by that the front end of a key rod is provided with a magnetic block. The utility model solves the problem of the extraction of an iron metallic foreign body by using the technical means. The utility model has the advantages of easy manufacturing and convenience.

Description

Magnetic key

The utility model is a kind of magnetic key.

Lockset is the fexible unit in order to insurance, can not open by lock owing to fill in foreign matter in the lock core hole sometimes, just can't open lockset when particularly entering foreign matter such as steel ball, steel wire head, iron nail and iron filings in the lock core hole.

The purpose of this utility model is: design a kind of magnetic key that can take out iron foreign body easily.

Key generally comprises its handle and key bar two parts, and the utility model then is that the mode that utilization is installed magnetic block at the front end of key bar realizes.

When iron foreign body enters lock core hole, the front end of key is probeed in the lock core hole, utilize magnetic block to the attraction of iron foreign body and foreign matter is derived lock core hole.

The utility model goes for the key of multi-form lock, but because the key cross section of magnetic lock is bigger, thereby than being easier to installation.And magnetic lock lock core hole inwall is comparatively smooth, also than being easier to take out foreign matter.For magnetic lock, for the weight that alleviates key can adopt the annular magnet piece.

The annular magnet piece then can be by passing its endoporus screw and key bar spin and realize the location of magnetic block.

In addition, all can be placed in the shell of magnetic lock key for the magnetic block of different shape, because its key bar of the key of magnetic lock partly is made up of its inner core and its shell, and magnetic block can be installed the place ahead that is located at inner core in the enclosure.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Fig. 1 is the phantom of the utility model embodiment one;

Fig. 2 is the phantom of the utility model embodiment two;

Wherein, 1-magnetic block, 2-screw, 3-shell, 4-inner core, 5-key bar, 6-handle.

Embodiment one:

What present embodiment was described is the key of magnetic lock, and it comprises its handle 6 and key bar 5 two parts.Its key bar 5 is had inner core 4 and its shell 3 of lock property pellet shot from a slingshot and is attracted the magnetic block 1 of foreign matter to form by it.Wherein, magnetic block 1 is a solid construction, and it is positioned at the front end of inner core 4, and shell 3 is placed in outside magnetic block 1 and the inner core 4.Embodiment two:

Present embodiment is described also to be the key of magnetic lock.Equally, it is made up of its handle 6 and key bar 6 two parts.The front end of its key bar 5 outsides has the magnetic block 1 of annular, has a screw 2 to pass the endoporus of magnetic block 1 and the front end face of key bar 5 spins.

The simple technological means of the utility model utilization has solved the problem of taking out the ferrous metal foreign matter, it Have be easy to process, make things convenient for, practical characteristics.
