Abstract

The utility model relates to a commanding clock which can automatically control the times of ringing and the time of ringing. The utility model is designed on the basis of an ordinary clock; so long as a dial is taken off, and a clock dial with simple structure and a pointer with magnetic field on the facade of a circuit are arranged on the back of the dial, the utility model is formed. The clock dial can be divided into three layers of circular ring discs has gaps and inserting slots of two sizes, and the gaps and the inserting slots are inserted by electrical bridges. A magnet is arranged on each cusp of an hour hand and a minute hand. The utility model has the advantages of simple structure and easy fabrication. The times of ringing and the time of ringing can be adjusted according requirements, parts do not need to be reformed, increased or reduced. The time of ringing is exact, the use range of the utility model is wide, and the utility model can be adopted by a school, an enterprise, an institution or a family.

Description

Commanding clock

The utility model is applicable to a kind of clock that can control number of rings and time automatically that units such as school, office, enterprise, family use, and we claim it to be Commanding clock.

In live and work, often gave in the past and decide the some time and make the desirable chronopher of something neither one and remind; influence working and learning through regular meeting, need send the special messenger to ring a bell in school, office, enterprise, need ring many times every day; usually forget to beat or miss the thing of beating, and people's spirit of ringing a bell is at full stretch.

The purpose of this utility model is to provide a kind of can control number of rings and jingle bell time automatically, can reduce labour's Commanding clock again.

Below in conjunction with accompanying drawing the utility model is described in detail.

The utility model is finished with the following method: Commanding clock is to design on the basis of ordinary clock, does not need the gear train of otherwise designed clock, need only take off clock face, and reverse side is loaded onto clock dial, sets up circuit, and the pointer that band magnetic field is loaded onto in the front gets final product.Critical piece, clock dial are divided into three layers, and ground floor large circle clock dial (1) adopts the non-magnetic induction foil material to make, and the outside of big garden ring clock dial is rasped to the strip slot (9) of inside direction, and slot is 60.The second layer is a middle annulus clock dial (2), and non-conductive material such as its employing plastics are made, and the stepped tooth (10) and the vee (11) of warpage made on inside and outside both sides, and outside inward direction warpage, breach are 60, and inner edge outward direction warpage, breach are 120.Each fixes a copper conductor (4) inboard, interior outside, and power supply stream flows through use.The 3rd layer is small circle ring clock dial (3), equally adopts the non-magnetic induction foil material to make with the large circle clock dial, and its inner edge has also been filed strip slot (9), and slot is 120.More than the breach and the slot of three layers of clock dial use for the plug-in bridge, electric bridge is to adopt a thin iron pin to be welded on iron pin one end with copper wire line (7), the other end is welded in the sheet metal (8) (metal beyond the deironing) of a little rectangular parallelepiped, makes to insert the latch of slot.Two identical electric bridges (5) (6) are inserted in respectively in the slot of clock dial ground floor and the 3rd layer by giving the time of deciding jingle bell.The hour hands of clock and minute hand are that aluminium flake is made, and two needle tips are embedded with magnetic patch, go to when two pins and give when fixing time, because the action of a magnetic field of two pins will give two electric bridges and the lead adhesive of fixing time, the conducting electric current reaches and gives the purpose of deciding jingle bell.

Circuit diagram (12) the 220V power connection, obtains the 6V electric current by transformer, passes through diode (2AP9) D again ₁～D ₄With capacitor C(16V100 μ f) rectification becomes direct current, and direct current is by two electric bridge (K switch on the clock dial ₁K ₂) again through the lead on first and third layer of garden ring clock dial, when electric bridge of hour hands adhesive, have only a K switch ₁Or K ₂Close relay

Can not start, must make hour hands and minute hand attract two electric bridges and conductor adhesive simultaneously, just can excite relay

Closure is connected the electric bell circuit, and last electric bell starts.When not needing jingle bell, but at this moment close current can not change the running of hour hands.

Fig. 1 is the clock dial front view of Commanding clock.

Fig. 2 is the circuit diagram of Commanding clock.

Advantage of the present utility model: (1) can with need by people season and requirements adjustment ring a bell the time with ring a bell number of times, need not change a social system and change any part. (2) make simply, with low cost, easy to use. (3) time of ringing a bell accurate, reduced the labour. (4) scope of application is wide, no matter school, enterprise, office and family all can adopt.

Most preferred embodiment of the present utility model: the critical piece clock dial of Commanding clock divides three layers, they all are mounted on the same face, get the size of radius R gained clock dial with the same center of circle, the external diameter R of ground floor large circle clock dial is 15CM, the R of internal diameter is 12CM, the external diameter R of middle annulus clock dial is 11CM, internal diameter R is 8.5CM, the external diameter R of the 3rd layer of small circle ring clock dial is 7.5CM, internal diameter R is 4.5CM, provide the large circle clock dial of assigning electric bridge and the slot of small circle ring clock dial to be of a size of long 1CM, the strip of wide 0.1CM. Breach on the middle annulus clock dial is high 0.5CM, outside 60, and the triangle of inner edge 120 five equilibriums, their interval is respectively arc length 1.15cm, 0.45cm.

Claims
