Abstract

The utility model relates to the improvement of a double timed multi-purpose timer with a double-shifting disc sleeve spindle structure. A ratchet wheel and a detent are adopted to replace a balance lever component designed originally, and the circular hole of the center of a large concave pit wheel is changed to a kidney shaped hole. The performance characteristics of the timer designed originally are reserved by the timer changed in the way, a load power supply can be timed to be automatically switched on in different time ranges, the timing turn-on and turn-off of the same load can be implemented, and two loads can also be switched on and switched off respectively according to sequence and different pens. New advantages are increased. The utility model has the advantages of simpler structure and good tightness. The utility model can be matched with a household appliance to be used.

Description

Multipurpose dual timing timer

The utility model relates to the improvement of a kind of pair of dial cover axle construction plesichronous multipurpose timer.

The application number that is proposed by me is 91215445.4 plesichronous multipurpose timers, structure has the original creation part, can be applicable, yet find that in making and using cover balanced lever parts are significant disadvantages, in timer, the thimble of balanced lever must move up and down along the hole on the top cover, therefore the necessary perforate of top cover, if this timer is contained in other household electrical appliance, then on this appliance panel, also answer perforate, this causes not closed state, dust enters easily, and the timer dial also need leave several grooves, and structure is comparatively complicated.

The utility model is at this shortcoming, and design one cover ratchet, detent mechanism replace above-mentioned equalizing feature, and making timer is totally-enclosed and compact conformation.

For this reason, the technical solution of the utility model is that the balanced lever parts in the former design are comprised balanced lever, thimble, balance weight, spring removes, and remove hole on the top cover and the groove on the dial, and on sleeve, set up a ratchet, between cog is corresponding with the dial scale on the ratchet, on top cover, set up an axle, a pawl component is housed on this axle, on the outer pit wheel round bump is set, an axle is connected by a spring on pawl component and the top cover.

The utility model embodiment is further described in conjunction with the accompanying drawings.

By Fig. 1, shown in 2, new improvement timer and former design compare, new improved timer is on former design basis these parts of balanced lever to be done an improvement, with balanced lever 22, thimble 23, balance weight 20, hole 24, spring 21, propping up sheet 18 removes, groove 2 is not set on the dial 1, and on sleeve 4, set up ratchet 43, by shown in Figure 7, can with sleeve 4, gear 6 is made one, corresponding between per tooth on the ratchet 43 with dial 1 scale, be arranged with axle 44 at top cover 10, on this axle a pawl component 45 is housed, show by Fig. 8, it comprises ratchet 46 and bottom centering block 47, have circular hole 49 on the ratchet, the round bump 48 that the centering block front end is the setting of circular arc and pit wheel 19 matches, by shown in Figure 9, spring 50 respectively with ratchet on circular hole 49 be connected with top cover lower shaft 51, distinguishing with former design a bit is to be to match with axle 5 in a kidney shape hole 52 in the middle of the pit wheel 19 in addition, the pit wheel can be rotated, the reed 25 of 4 band silver contacts in the timer base 12 wall grooves with axle 5,26,27,28 is constant.

Operation principle to plesichronous multipurpose timer after improving is summarized as follows, timer is before energising work, and at first the time of carrying out presets, by Fig. 2, shown in 3, the initial condition of timer, i.e. twice dials 1,3 are in 0, also are that reed 15 is in inside and outside pit wheel 17, in 19 the pit, at this moment, projection 48 on the pit wheel 19 is pushed ratchet centering block 47 open, make ratchet break away from ratchet, so dial 1 can rotate, give and set two dial required times, then need stir dial 1 earlier, also promptly drive pit wheel 17 and leave 0,, make axle 8 produce idle running with respect to gear 7 owing to be contained in riveted sheet effect on the axle 8 by sleeve 4, this moment, axle 4 drive indent wheels 17 were boss 15 jack-up of reed 25, dial 1 can toggle it on the position of required preset time, and then carries out the time preset of dial 3, and dial 3 drives outer pit wheel 19 by axle 5 and leaves 0, the boss 15 of reed 25 is by outer pit 19 surperficial jack-up at this moment, at this moment, dial 3 can toggle it to required preset time position, to this moment, the two dial times of having finished were given setting, because dial 3 leaves 0, when the projection on the outer pit wheel 19 broke away from ratchet centering block 47, ratchet 46 arrived the state with ratchet engaged under the effect of spring 50, make dial 1 fixing, the timer winding diagram is by shown in Figure 4, when two dials are in 0, and contact 30,33 disconnect, power supply is not switched on, timer is not worked, when two dial times preset finish after, reed boss 15 is by outer pit wheel surface jack-up, as shown in Figure 5, this moment contact 30,33 connect contact 29,31 connect, and this moment, load A and synchronous machine D all switched on, load B no power, timer work this moment, by shown in Figure 1, synchronous machine drives train and rotates, by with retarding stage in coaxial gear 11 and 14 engagements of travelling gear 13, riveted sheet 16 and axle 5 are rotated thereupon, the pit wheel 19 that is enclosed within on the axle 5 is rotated, at this moment, outer recessed 19 upper protruding blocks 48 of taking turns break away from ratchet centering block 47, ratchet and ratchet engaged make dial 1 fixing, thereby gear 6 and pit wheel 17 are fixed, at this moment gear 7 is fixing, and the riveted sheet 9 on the axle 8 produces relative rotation with gear 7, thereby guarantees the train operate as normal, when pit wheel 19 is got back to 0 through the fixed time shown in the dial 3, this moment as shown in Figure 6, reed boss 15 falls into the groove of pit wheel 19, makes reed 25 reply the part distortion, and contact 31 breaks away from contact 29, and contact 33 still contacts with contact 30, contact 31 contacts with contact 32, and load this moment a-power supply disconnects, and the load B-source is switched on, synchronous machine continues to drive the train transmission, because this moment, dial 3 is got back to 0 point, and outer pit is taken turns 19 upper protruding blocks 48 and pushed ratchet centering block 47 open, make ratchet break away from ratchet, therefore the pit wheel 17 that drives on the sleeve 4 of the engagement of train by gear 7 and gear 6 rotates, because the boss 15 on this moment reed 25 has been embedded in the groove of pit wheel 19, so riveted sheet and gear 14 that axle 5 is installed on the axle 5 produce relative rotation, guarantee the operate as normal of train, when the time that pit wheel 17 presets via dial 1 is got back to 0, at this moment, the boss 15 of reed 25 falls into the groove of pit wheel 17, at this moment, reed 25,26 distortion full recovery, contact 30 disconnects with contact 33, the power supply of load B also is cut off like this, synchronous motor rotates and stops, and timer quits work, and realizes load B timing Power-On like this, deenergization behind the work certain hour, this has just realized disconnecting by preheating setting time after first load is connected, and meanwhile connects the 2nd load and disconnects through another preheating setting time again, and the above is through improved timer operation principle, owing to only substituted former balance lever part with click, outer pit 19 centers of taking turns have slot and match with axle 5, and all the other are constant, thereby still keep the performance characteristics of timer in the former design, can realize that timing automatic switches on and off load power source in the different time scope, same load is realized regularly switching on and off, also can be sequentially to two loads, the different time scope switches on and off successively, and increased new advantage, timer construction is simpler, and good seal performance is easier and household electrical appliance are supporting applies.
