Description

The electromagnetic lock of convertible lock-out state

Technical field

The utility model relates to a kind of electromagnetic lock, relates in particular to a kind of convertible lock-out state, has wide range of applications, and can make the electromagnetic lock of the more smooth and easy and certain convertible lock-out state of the buckle process of button hole and magnetic induction rod.

Background technology

General electromagnetic lock all is the state that presents locking usually when not switching on, and to reach the purpose of locking, when waiting to need to open, makes its energising again and unblanks; But under some special situation, (have a power failure), be in unlocked conditions, then must use the electromagnetic lock of when energising locking when outage (that is unblank) in order to ensure lockset as fire; But, the lock-out state of existing electromagnetic lock is to unblank when being fixed in energising or the state of locking when switching on, the shortcoming that existence can't the conversion lock-out state.

Summary of the invention

For overcome existing electromagnetic lock exist can't the conversion lock-out state shortcoming, the utility model provides a kind of electromagnetic lock of convertible lock-out state, it has convertible lock-out state, the effect that has wide range of applications, and can make the buckle process of button hole and magnetic induction rod more smooth and easy and certain.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of electromagnetic lock of convertible lock-out state is characterized in that, comprising: a housing, one end are provided with a perforation, and the side is provided with a side cover; One electromagnetic coil is provided with the magnetic induction rod that runs through, and this magnetic induction rod is provided with a returning spring, and electromagnetic coil is installed on enclosure interior, and this magnetic induction rod is scalable in this perforation; One snap close, to being provided with a button hole by the magnetic induction rod, button hole is formed with the guiding face towards the magnetic induction rod.

The electromagnetic lock of aforesaid convertible lock-out state, wherein an end of magnetic induction rod is thin end, and aforementioned returning spring is sheathed on this thin end, runs through electromagnetic coil from the upper end again, make this thin end have the lower end that externally threaded front end stretches out electromagnetic coil, and be located at this front end with a positioning head spiral shell and fixed.

The electromagnetic lock of aforesaid convertible lock-out state, its middle shell is provided with a confined planes in the extension of the outer end of perforation.

The beneficial effects of the utility model are, it has convertible lock-out state, the effect that has wide range of applications, and can make the buckle process of button hole and magnetic induction rod more smooth and easy with really.

The specific embodiment

At first, see also shown in Fig. 1,2, the utility model includes:

One housing 10, one end are provided with a perforation 101, and a side cover 102 is installed in the side; Extend in the outer end of perforation 101 in addition and be provided with a confined planes 103;

One electromagnetic coil 11 is provided with the magnetic induction rod 111 that runs through, and is provided with a returning spring 112 at magnetic induction rod 111, and electromagnetic coil 11 then is installed on housing 10 inside by screw 113, and this magnetic induction rod 111 is scalable in this perforation 101.

One snap close 12, to being provided with a button hole 121 by magnetic induction rod 111, this button hole 121 is formed with the guiding face 122 towards magnetic induction rod 111.

Moreover, one end of this magnetic induction rod 111 is thin end 111a, aforementioned returning spring 112 is sheathed on this thin end 111a, run through electromagnetic coil 11 again from the upper end, make this thin end 111a have the lower end that externally threaded front end 111b stretches out electromagnetic coil 11, and be located at this front end 111b with a positioning head 114 spiral shells and fixed.

Based on said structure, the magnetic induction rod 111 of this electromagnetic coil 11 is to borrow its returning spring 112 and maintain the state that an inclined to one side end protrudes out when "on" position not, when logical constantly, then protrude out toward other ends because of coil excitation drives magnetic induction rod 111; As shown in Figure 3, when the installment state of electromagnetic coil 11, be the perforation 101 that the magnetic induction rod 111 of "on" position is not protruded out this housing 10, the electromagnetic lock of unblanking (locking during outage) in the time of then can mixing into energising with this snap close 12; Oppositely installing, promptly as shown in Figure 4, this magnetic induction rod 111 fails to protrude out this perforation 101 in "on" position not, and mixes into the electromagnetic lock of locking (unblanking during outage) when switching on snap close 12.

In addition, as shown in Figure 5, this snap close 12 can be forward, side direction or multi-faceted setting angle such as oblique, and can lock by forward, side direction or multidirectional slipping into such as oblique, and allow button hole 121 and this magnetic induction rod 111 form the relation of buckles, make its installable angle very extensive, be to be applied to layback to slip into lock (as sliding) as shown in Figure 6, or as shown in Figure 7, be applied to tangent slip into and lock (as door lock), have the effect that has wide range of applications.

This shows that the utility model is as long as change the direction that is provided with of its electromagnetic coil 11, be in regard to convertible lock-out state that energising is unblanked or the different locking states of the locking of switching on; Again, snap close 12 can be slipped into by multidirectional, unblank or the state of locking and forms by the buckle relation of its button hole 121 and magnetic induction rod 111, and these button hole 121 formed guiding faces 122, can allow the buckle process more smooth and easy and certain.The utlity model has convertible lock-out state and have wide range of applications, have the smooth and easy and certain effect of locking buckle process again.

In sum, the structure that the utility model disclosed by former times is not had, and really can reach the effect of expection, and has and can supply industrial utilization, meets novel patent requirement fully, so file an application in accordance with the law.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
