Description

The multi-feature telephone protective cover

The utility model relates to a kind of telephone set protective cover that is constituted, is equipped with lockset by cover cap and machine box between cover cap and machine box.

Along with the development of society, the use of phone more and more widely, still, no matter be office telephone, home telephone, or public telephone, in actual the use, but there are the following problems respectively:

1, in the prior art, do not have special-purpose telephone set protective cover, phone is polluted by dust or other filth inevitably, has had a strong impact on the serviceability of phone, and especially in the relatively poor place of environment, its failure rate obviously improves, and shorten useful life greatly.

2, make a phone call to be unable to do without telephone number, but existing telephone set, its body itself does not have to deposit the place of more number, and number is not made troubles to use at random.

3, telephone set of the prior art, all be with ring back tone as the calling cue, this voice signal can be waken up with a start the people from dream.In actual the use, the people for needs are had a rest can only bother with release earlier with receiver off-book.

4, in some occasion, the owner of phone adopts some simple and crude machine boxes, and loads onto lockset on the machine box, and is both unbecoming though this has satisfied the requirement of phone special use, also inconvenient.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, provides a kind of and collects protection, places telephone number, ring sound is converted to the signal lamp indication and can makes phone become special-purpose multi-feature telephone protective cover.

The purpose of this utility model is achieved through the following technical solutions.

The utility model is made of cover cap and machine box, between cover cap and machine box lockset is housed.

Architectural feature of the present utility model is:

A, employing coded lock, the cover cap top has the microphone window, and machine box both sides have ventilation hole, and machine box bottom is provided with the carton drawer,

B, the phone change-over circuit is set, this circuit is between phone network signal end line (I, II) and telephone set S1 many grades of change over switch K1 to be set, and the circuit of being selected respectively by change over switch K1 also comprises: the ring indicating circuit that is made of filter capacitor C1, C2, C3, rectifier cell D1-D4 and indicator light S2; The automatic box opening phone answering circuit that constitutes by filter capacitor C4, C5, C6, rectifier cell D5-D8 and solenoid S3, magnetic conducting strip S4, conducting strip contact K2, K3;

On machine box madial wall, fixing spring bumps pearl on the cover cap of correspondence position in the top by strut fixation for c, described magnetic conducting strip S4, and solenoid S3 and conducting strip contact K2, K3 are separately fixed on the machine box of its lower end correspondence position.

The utlity model has following advantage.

1, dustproof, waterproof, entrant sound of the utility model, keep a public place clean.

2, the utility model adopts coded lock, when needing, can only connect, and can not beat.Coded lock is easy to use, and security performance is good, and its password can arbitrarily be changed.

3, the utility model carton drawer is used to place record-paper, can greatly make things convenient for use.

4, the setting of the utility model phone change-over circuit not only makes phone strengthen to some extent on function, makes original bell signal be converted to the signal lamp indication, and, when having telephone signal to come to visit, can open box automatically and meet sb. at the airport.

Fig. 1 is the utility model master TV structure schematic diagram.

Fig. 2 is the utility model backsight structural representation.

Fig. 3 is the utility model automatic lid closing/opening structural representation.

Fig. 4 is the utility model circuit theory diagrams.

By the following examples, in conjunction with the accompanying drawings, the utility model is further described.

Embodiment:

Referring to Fig. 1, Fig. 2, protective cover is made of cover cap 1 and machine box 2, and is fixedly connected by spring hinge 11 at the back of cover cap 1 with machine box 2, between cover cap 1 and machine box 2 lockset 4 is housed.In the present embodiment, adopt coded lock 4.The unlatching password of coded lock 4 can reset when needed, to strengthen its confidentiality.

As shown in Figure 1 and Figure 2, have microphone window 3 at the top of cover cap 1, the position of microphone window 3 and form and microphone are corresponding, can be as shown in the figure vertically, also can be laterally use so that be fit to the transverse electric phone.Be connected by hinge 12 between microphone window 3 and the cover cap 1.Machine box 2 both sides have ventilation hole 14, and the setting of ventilation hole 14 is in order to guarantee that bell signal is not cut off.Machine box bottom is provided with carton drawer 13, in the carton drawer 13, can place record-paper 5.In the present embodiment, adopt roll paper, as shown in the figure, spool 6 and volume handle 7 are set, record-paper 5 is wound on the spool 6, and the paper end is fixed on carton drawer 13 collar extension.During use, outwards spur carton drawer 13 and get final product, after using, scrolling volume handle 7, wraparound record-paper.Also can on spool 6, wind spring be set, carry out auto reeling.Shown in Fig. 2, be provided with binding post 10, in order to insert phone network signal end line at the back of machine box 2.

Referring to Fig. 4, the phone change-over circuit is set, this circuit is between phone network signal end line I, II and telephone set S1 many grades of change over switch K1 to be set, and the circuit of being selected respectively by change over switch K1 also comprises: the ring indicating circuit that is made of filter capacitor C1, C2, C3, rectifier cell D1-D4 and indicator light S2; The automatic box opening phone answering circuit that constitutes by filter capacitor C4, C5, C6, rectifier cell D5-D8 and solenoid S3, magnetic conducting strip S4, conducting strip contact K2, K3.Indicator light S2 wherein and change over switch K1 are separately positioned on machine box appearance, and label 8 is indicator light S2 as shown in Figure 1, and label 9 is change over switch K1.

As shown in Figure 3, magnetic conducting strip S4 is fixed on machine box 2 madial walls by pole 15, and fixing spring bumps pearl 16 on the cover cap 1 of correspondence position in the top, and solenoid S3 and conducting strip contact K2, K3 are separately fixed on the machine box 2 of its lower end correspondence position.As shown in Figure 3, on machine box 2, also be provided with simultaneously and manually bump pearl 17,, manually open box so that not under the lock condition, press and manually bump pearl 17 at coded lock.

Behaviour in service is as follows:

1, locking coded lock from the conversation of microphone window off-hook, can not outwards be dialed.

Change over switch K1 connects phone network holding wire a, b and phone wiring g, h, and visiting signal is a ring back tone, and off-hook can be conversed.

Change over switch K1 connects phone network holding wire a, b and indicating circuit e, f, and visiting signal is by the luminous indication of indicator light S2.When index signal is arranged, at first stir change over switch K1, phone network holding wire a, b and phone wiring g, h are connected, off-hook conversation again.

2, open coded lock, answering or dial can be random.

Except that as the identical use of locked condition, when change over switch K1 is allocated to phone network holding wire a, b and end line c, d are connected, when visiting signal was arranged, coil S3 got electric, and magnetic conducting strip S4 is because the adhesive of solenoid S3, connect conducting strip contact K2, K3, phone is access in phone network, meanwhile, because magnetic conducting strip S4 upper end pushes spring latch lock, cover cap is opened automatically, realizes opening automatically the function that box is met sb. at the airport.
