Abstract

The invention pertains to the technical filed that: the invention relates to an internal diameter telescopic ring-shaped mobile telephone shell with a theft-proof function. The technical problems needing to be solved are that: the limitation of the shape of the current mobile telephone is overcome and the safety of carrying the traditional mobile telephone is improved. The technical proposal is that: the main body and the battery of the mobile telephone are embedded into a ring-shaped shell with a fixed size and connected through a power line; the surface of the inner ring of the ring-shaped shell is provided with a ring-shaped strip air bag which can be inflated and deflated freely; the whole shape of the mobile telephone provided with the shell is ring-shaped; when the ring-shaped air bag is deflated, the diameter of the inner ring of the ring-shaped shell of the whole mobile telephone is enlarged so that the palm can go through the mobile telephone to wear the telephone on the wrist; when the ring-shaped air bag is inflated, the diameter of the inner ring of the ring-shaped shell of the whole mobile telephone is shortened so that the palm cannot go through the mobile telephone and the telephone is locked on the wrist. The main purpose is to prevent theft and loss. In the picture, (1) represents the main body of the mobile telephone, (2) the power line, (3) the ring-shaped shell, (4) the battery of the mobile telephone, (5) the ring-shaped strip air bag, (6) a check valve, (7) a blast pump, (8) an airway and (9) a deflation valve.

Description

Inside diameter telescopic anti-theft ring-shaped mobile phone outer casing

Affiliated technical field

The present invention relates to a kind of interior diameter extension type annular mobile phone shell with anti-theft feature

Technical background

At present, known phone housing shape is complicated various, but the shell of conventional mobile phone does not possess anti-theft feature, and user's fail safe when carrying mobile phone do not ensure, has stolenly, and the possibility of loss fixes on cell-phone lock on the wrist, and fail safe is than higher.

Summary of the invention

Fail safe when carrying for improving existing portable mobile phone, the invention provides a kind of mobile phone ring-shaped outer casing, have the circular ring type of the complete fuselage of mobile phone of this shell for sealing, its outer fixed diameter, inner ring diameter is scalable, this mobile phone is worn on wrist by the user,, can easily wear on wrist or extract along the telescopic ring-shaped shell of diameter by interior.

The technical solution adopted for the present invention to solve the technical problems is: the fuselage and the battery of mobile phone are embedded in the ring-shaped outer casing of a fixed size, fuselage is connected by power line with battery, install and freely to inflate in the inner peripheral surface of annular outer cover, the ring-like strip air bag of venting, the complete fuselage of mobile phone with this shell is a circular ring type, when ring-like air bag emits air, it is big that the inner ring diameter of whole mobile phone ring-shaped shell becomes, can allow palm partly pass wears mobile phone on wrist, when ring-like air bag charges into air, the inner ring diameter of whole mobile phone ring-shaped shell diminishes, and at this moment because palm can not pass mobile phone again, mobile phone is locked in wrist.

The invention has the beneficial effects as follows, wear and be locked in by the user in use on the wrist, can effectively reduce possibility stolen or that lose, protection user's mobile phone safety, wear or extract comparatively convenient.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples

Fig. 1 is a complete side schematic diagram of the present invention

(1) handset among Fig. 1, (2) power line, (3) ring-shaped outer casing, (4) battery of mobile phone, (5) ring-like strip air bag, (6) Non-return air valve, (7) inflating pump, (8) wireway, (9) vent valve

Embodiment

In Fig. 1, (1) handset is connected by (2) power line with (4) battery of mobile phone, embed (3) ring-shaped outer casing together, (5) ring-like strip air bag of installing in the inner peripheral surface of (3) circular ring type shell emits air in the air bag by (9) vent valve, the inner ring diameter of whole mobile phone ring-shaped shell is diminished, allowing palm pass the mobile phone ring-shaped outer casing wears it on wrist, compression (7) inflating pump extruding air, air is under the control of (6) Non-return air valve, progressively to (5) ring-like strip airbag aeration, inner ring diameter until whole mobile phone ring-shaped shell becomes big, is about to cell-phone lock and fixes on wrist.

Claims

1. ring-shaped shell mobile phone, the outside dimensions of the ring-shaped shell of mobile phone immobilizes, the inflation and the venting of the bar shaped ring-shaped gasbag by inner peripheral surface, inner ring diameter can stretch, and the monolithic case form is the mobile phone of ring-type.

2. according to claim 1 described ring-type mobile phone outer casing, it is characterized in that: outside dimensions immobilizes, the ring-type mobile phone outer casing that inner ring diameter can stretch.
