Description

Multifunctional clock control switch for electrical appliance

The utility model belongs to a kind of electrical equipment time switching device.

At present, the general timing of the time switch on the market is short, and function singleness (can only open or close, and can only control one group of electrical equipment) can not be controlled the electrical equipment of semiconductor type.And the time switch on some electrical equipment (as the clock radio cassette player) is not cut off the electricity supply in off position the time fully, and parts such as its power transformer continue consumed power still in work, simultaneously, have also brought unsafe factor to the user.Therefore, develop a kind of multifunctional electric appliance clock controlled switch and just seem even more important and urgent.

The purpose of this utility model is exactly at above-mentioned situation, and the long clock controlled switch of a kind of multi-functional, timing has been invented in research.And select for use different functions to make up, and can form series of products, thus dealing with various requirements.

Based on above-mentioned purpose, the utility model has designed a kind of scheme: (can adopt watch and clock movement by a timing movement, mechanical type and electronic type all can) drive the gear that can swing, the gearing mesh of gear that this can be swung and timing movement, they are hinged with a connecting rod, and two connecting rods that the other end and an end have slotted eye are hinged through slotted eye.One of two connecting rods one end that has slotted eye draws spring to fix with one, has refilled the another one spring simultaneously, and this draws spring one end to be fixed on this connecting rod that has slotted eye, and the other end is fixed on the connecting rod of wobble gear.The other end that has two connecting rods of slotted eye can rotate around point of fixity with two one ends respectively, and the other end that has a connecting rod of steamboat is hinged, but the angle of the axostylus axostyle of steamboat and this connecting rod cannot be 90 °.Simultaneously, this end also is equipped with a contact, fixes two contacts respectively in the both sides of contact, these two six contacts of contact and four fixed contact forming circuits movably.These six contacts and input, output terminal make up with specific combined switch.Above-mentioned two steamboats contact with two recessed wheels respectively, on recessed axle of taking turns gear are installed simultaneously, and wobble gear can be respectively under the effect of its connecting rod and above-mentioned two gearing mesh.This two cover is recessed take turns and have steamboat defend against a siege and contact, the contact of end points constituted two regularly starting switch A and B, see Fig. 1 (also can adopt other Starting mode, as cam etc.).Simultaneously the timing movement links to each other with the gear case of a variable-ratio again, connects two cams (or without the gear case speed change, and adopt fixedly rotation period mode) simultaneously from the gear of gear case output, and a touch switch is equipped with in two cams centre, sees Fig. 2.The utility model also has a special lead-out terminal, and promptly undersized thermometal thin slice therebetween one insulation course is seen Fig. 3.

The utility model has the advantages that: simple in structure, reliable operation, function is many, volume is little, timing is long, maneuverability, applied range.

Be two embodiment below:

Embodiment 1:

According to control switch in the pincers worker of wiring diagram Fig. 4 assembling is the more comprehensive time switch of a kind of function, and specific combined switch J has four retainings (I, II, III, IV), and its connected mode is: I is represented to import live wire and is linked to each other with b, d end; II is represented to import live wire and is communicated with a, d end; III is represented to import live wire and is linked to each other with a, e ' end; IV is represented to import live wire and is communicated with e ', b end.Switch S beats that e ' and e end communicates when φ keeps off, and c, e end links to each other when ψ.Switch R beats that f directly communicates with output terminal when θ keeps off, f, g end link to each other (K is sealed in the circuit) when β.Various output states see attached list 1.

Recessed among Fig. 1 taken turns 20,21 and held and do timing setting, and its circumferential section working time is 12 hours.During normality (being that steamboat 8 is in groove), contact b, c link to each other; Contact d, f communicate.When timing setting B (rotate recessed take turns 20 make steamboat 8 on circumference): contact a, c link to each other, thereby connecting rod 7 drivening rods 5 and then pulling connecting rod 4 mesh gear 3 and 12 to be driven and recessedly take turns 20.When it is finished (when steamboat 8 falls into groove), draw spring 9 pulling connecting rods 4 that gear 3 and 12 is broken away from.If A has also carried out timing setting (this moment contact e, f communicate), gear 3 and 13 is meshed drive and recessedly take turns 21 thereby then draw spring 9 will spur connecting rod 4.After finishing, thereby draw spring 10 pulling connecting rods 6 to promote connecting rod 4 gear 3 and 13 is broken away from, but can not make gear 3 and 12 engagements.

Cam C, D among Fig. 2 have identical rotation period, make them can not pass through K switch simultaneously by stop means, and their touch switch are opened, a pass, the time interval can be passed through rotation C(or D) adjustable continuously.Rotation period can utilize the gear of the gear case 19 of speed change to set, as half an hour, one hour etc.(also can adopt the fixed cycle mode) without the gear case 19 of speed change

Adopt the device of said structure to mainly contain following function:

One. can control two groups of electrical equipment simultaneously: 1. a liang group anisochrouous is regularly opened; 2. two groups of anisochrouous regularly close; 3. anisochrouous is opened and another group pass for one group; 4. regularly close again after one group being carried out timing and opens (can carry out timing simultaneously to another group opens); 5. carry out regularly opening again after timing is closed (can carry out timing simultaneously to another group closes) to one group.Time is adjustable continuously in 0～24 hour.

Two. when R is opened to β, when carrying out aforesaid operations, also can carry out periodicity switching operation.

Three. be furnished with the special lead-out terminal of Fig. 3, can semiconductor etc. the electrical equipment of use dry cell carry out above-mentioned control.

Four. be furnished with dial plate and pointer, can doublely do to such an extent that hour hands use, the socket that also can work as belt switch simultaneously uses.

Embodiment 2:

The clock controlled switch that adopts wiring diagram Fig. 5 assembling is a kind of simple, practical, position that cost is low.The double hour hands of doing use, and the timing movement can be selected general time movement without watch and clock movement for use, as selects the time movement of common mechanical formula timer for use.Simultaneously, also can simplify two regularly interlinked mechanisms between starting switch A, B, as in Fig. 1, replace connecting rod 5 with plain connecting rod, its length should satisfy: when with recessed 20 steamboats that join 8 of taking turns on circumference the time, gear 3 meshes with 12; And when steamboat 8 falls into groove, gear 3 should with 13 the engagement.Draw spring 9,10 to remove, one of connecting rod 6 usefulness draw spring to replace.Simultaneously, also can be being simplified to sliding contact with the recessed steamboat that contacts that rolls of taking turns.Like this, also can be being simplified to sliding contact with the recessed steamboat that contacts that rolls of taking turns.Like this, just convenient after second step, timing setting A finished, gear 3 can break away from gear 13, thereby further reduces cost.Switch S is when I, and the input live wire links to each other with b; When beating in II, the input live wire communicates with a, and its output state sees attached list 2.
