Description

The antitheft mobile phone cover

Technical field:

The utility model relates to a kind of cell-phone cover with anti-theft alarm function.Belong to the daily living article technical field.

Background technology:

Existing antitheft mobile phone cover is made up of cell-phone cover and device burglar alarm two parts on cell-phone cover.Its burglar alarm generally is made up of two or more switches.One is anti-thefting alarming switch in two switches, two releasing alarm switches when using.And second simple as easy as rolling off a log people who is understood its function of switch removed before sending alarm signal, and complicated operations is got up and bothered, and price is bigger, is not suitable for frequent use.

Summary of the invention:

The purpose of this utility model is to provide a kind of novel anti-theft cell-phone cover that can't remove alarm switch before burglar alarm sends alarm signal.

Technology contents of the present utility model is: a kind of antitheft mobile phone cover, comprise cell-phone cover and the burglar alarm of device on cell-phone cover, be characterized in that burglar alarm comprises spring self-lock switch, power supply and the loud speaker that pipes, spring self-lock switch, power supply and the loud speaker that pipes are connected in series, and the button of spring self-lock switch places in the mantle and contacts with hand set machine shell.Utilize the closed anti-theft alarm function of realizing of self-locking of spring self-lock switch, self-locking disconnects and realizes removing warning function.When normally using mobile phone, the spring self-lock switch becomes the self-locking off-state.When mobile phone is put into mantle and covered the mobile phone upper shield, the spring self-lock switch is removed the self-locking off-state being depressed.When opening mantle or broken when extracting machine, the self-lock switch button flicks fully under spring action and is in the self-locking closure state, and the loud speaker that pipes powers alarm.Only need click button again during normal the use, the switch self-locking disconnects.

Therefore, the utility model can give the alarm when uncapping or break cover robber machine, and because the self-lock switch self character, when self-lock switch is in not self-locking off-state, only after the self-locking closure, just can reach the self-locking off-state, promptly before burglar alarm sends alarm signal, can't remove, realize real effective anti-theft alarm function from face.Because the crowd of applicable use mobile phone easy and simple to handle.
