CN2428855Y - Numeral safety circuit switch - Google Patents

Abstract

The utility model relates to a numeral safety circuit switch, comprising an exterior shell body, a numeral rotating disk assembly and a numeral display window. The utility model uses the numeral rotating disk assembly to replace the existing locking type circuit switch lock core, so the original prepared key is replaced by human's numeral memory, and thus the utility model is used more convenient and safely; the utility model also has the advantages of low manufacture cost, stable performance, long service life, and low failure rate.

Description

Safety digital circuit switch

The utility model relates to a kind of safety digital circuit switch.

As everyone knows, we generally adopt locking-type contactor (as automobile, motorcycle etc.), but there am following defective in this prior art for for the purpose of making contactor security personnel at present: the one, and it is being opened when using, the end user must have the key of being joined, and not so can not open use.Just in case lose, must be equipped with again; The 2nd, though its structure genus is simple, security personnel's poor-performing, general lawless person destroys the purpose that (as inserting with sheet metal) can reach destruction or steal a little.

The utility model can overcome the above-mentioned defective of prior art, provides a kind of simple in structure, the easy to use and stronger safety digital circuit switch of security personnel's performance.

The utility model comprises; The external form housing with install within it digital rotating disk assembly and device at the digital display window on its surface.

Owing to adopted above technical solution, the utility model has substituted the lock core device of existing locking-type contactor with digital rotating disk assembly, digital memory with the user has replaced the key that is equipped with, the user must not carry key, also removed the sorrow of losing from, as long as remember selected password.Adopt the password of long number simultaneously, improved security personnel's performances (height of its security can arbitrarily be selected some figure places for use as required during fabrication, and high more its security personnel's performance of figure place is good more) widely.And during fabrication, cost is also lower.And with this technology and the intelligent high-tech that has just emerged now relatively, it has again makes easyly, with low cost, easy to use, and the life-span is long, and is stable and reliable for performance, and failure rate is low, and generally need not maintain and change tangible advantage such as zero accessory.

Now further illustrate know-why of the present utility model and feature again in conjunction with Figure of description.

Accompanying drawing 1: circuit on-state figure.

Accompanying drawing 2: circuit interruption state diagram.

As shown in Figure 1: the utility model comprises external form installation housing (1), digital rotating disk assembly (2) (it comprises turning collar and the central rotating shaft that amplexiform mutually in several inside and outside gardens) and digital display window (3) (digital figure place is corresponding with the rotation number of turns).Here be example (disk middle spindle and three peripheral turning collars) with three figure places.The outer garden of central shaft face is set a conductive contact, the a certain desired location of all simultaneously turning collars all is provided with a conductive contact of the inside and outside garden of connection face, all the other positions are all insulator (comprising central shaft), one electrode inserts the central shaft conductive contact, and another electrode contacts with the outer garden of the turning collar face of outermost.Like this when having only all when turn-taking with axis that all modulation is to selected digital position, all turning collars and the conductive contact of axle are all arranged point-blank, electric current just leads to the conductive contact of central rotating shaft by the conductive contact of all turning collars from the contact of the turning collar of outermost like this, and circuit has just been connected like this.

As shown in Figure 2: as all rotating disks and central shaft being turned except that selected number other when digital arbitrarily, their conductive contact just can not be point-blank so, and circuit has also just interrupted like this.

Claims (1)

1, a kind of safety digital circuit switch comprises: profile housing (1) and the digital rotating disk assembly (2) (comprising several turning collars and central rotating shaft) and digital display window (3) installed within it;

It is characterized in that the outer garden face of an electrode with outermost one turning collar of rotating disk assembly touched mutually; Another electrode inserts the outer garden face one of central shaft and sets on the conductive contact; The inside and outside garden face of all turning collars all phase mutual connection pastes, and at a certain desired location of all turning collars one conductive contact that connects inside and outside garden face is set all, and the conductive contact position of all turning collars all has password separately to show.
