Embodiment
embodiment mono-, the multi-stage timer as shown in accompanying drawing 1-accompanying drawing 4, a kind of timer that has fixed frequency comprises: timer clamping plate 1;
be arranged on the actuating unit 2 on timer clamping plate 1, actuating unit 2 generally includes the great wheel 21 with clockwork spring 22, rotates great wheel 21 and tightens clockwork spring 22, thereby make actuating unit 2 produce power;
the escapement 3 discharging for controlling actuating unit 2 power, escapement 3 comprises around wheel shaft 313 and is rotatably connected on escape wheel 31 on timer clamping plate 1, is rotatably connected on the escapement tilting member 32 that coordinates running with escape wheel 31 escapements on timer clamping plate 1 around swinging axle 321, in addition, the escapement 3 of this timer that has fixed frequency also comprises the escapement 33 and the hairspring 34 that swing for controlling escapement tilting member 32, escapement tilting member 32 is forked, so-called escapement lever;
be arranged on the transmission mechanism 4 between actuating unit 2 and escapement 3, in prior art, transmission mechanism 4 consists of multiple travelling gears, the number of travelling gear is determined according to actual needs, in the present embodiment, as shown in accompanying drawing 3,4, transmission mechanism 4 comprises the first drive 41, the second drive 42 and the 3rd drive 43 that arrange between great wheel 21 and the following escape wheel of mentioning 31.
below be all prior art, do not describe in detail.
as shown in accompanying drawing 3-8, the multiple escape wheel sheets of escape wheel 31 including escape wheel substrate 311, multiple escape wheel sheets interfix and taking wheel shaft 313 as center of rotation, tooth on multiple escape wheel sheets claims escapement tooth, the number of teeth is not identical, swinging axle 321 can be along being arranged on timer clamping plate 1 axially slidably, on timer clamping plate 1, be provided with for control escapement tilting member 32 along swinging axle 321 move axially and make escapement tilting member 32 can only match with an escape wheel sheet at one time running controlling organization 5.
as shown in accompanying drawing 5-7, the number of teeth on multiple escape wheel sheets increases progressively successively taking the number of teeth of escape wheel substrate 311 as benchmark, and the number of teeth on multiple escape wheel sheet is set to preferably mutually exponentially.Tooth on each escape wheel sheet is evenly distributed in periphery.Thereby make escapement tilting member 32 no matter which escape wheel sheet to coordinate running with, can make actuating unit at the uniform velocity export release power.
tooth on the multiple escape wheel sheets respectively projection in the plane at escape wheel sheet place coincides.
in the present embodiment, escape wheel sheet has two, for escape wheel substrate 311 and escape wheel tag 312, the number of teeth on escape wheel substrate 311 is few, as it is three, the number of teeth on escape wheel annex 312 is 15, the output rate of release of actuating unit when escapement tilting member 32 matches with escape wheel substrate 311,5 times of quick output rate of release of actuating unit in the time that escapement tilting member 32 matches with escape wheel tag 312.
multi-stage timer also comprises the elastic component 6 that makes escapement tilting member 32 be tending towards matching with escape wheel substrate 311 running.
because escape wheel sheet only has two, so the structure of the controlling organization adopting in the present embodiment is as follows, as accompanying drawing 1, 2, shown in 9, controlling organization 5 comprises along the direction of axis line that is parallel to swinging axle 321 and is slidably arranged in the speed control rod 51 on timer clamping plate 1, rotate or be slidably connected at the button 52 sliding for controlling speed control rod 51 on timer clamping plate 1, on speed control rod 51, there is the first contact part 511 and the second contact part 512, swinging axle 321 is arranged between the first contact part 511 and the second contact part 512, the both ends of swinging axle 321 respectively with the first contact part 511, the second contact part 512 is inconsistent.Elastic component 6 is arranged between speed control rod 51 and timer clamping plate 1.Shown in accompanying drawing 3,5, elastic component 6 is extension spring, and in the situation that not controlling speed control rod 51, under the effect of elastic component 6, escapement tilting member 32 is stablized and coordinated running mutually with escape wheel substrate 311.When pressing after button 52, the elastic force control speed control rod 51 that button 52 overcomes elastic component 6 slides, and speed control rod 51 drives swinging axle 321 to move axially, and shown in accompanying drawing 4,6, makes escapement tilting member 32 running that matches with escape wheel tag 312.After control button 52 resets, under the effect of elastic component 6, speed control rod 51 resets, and synchronously, swinging axle 321 is axially pulled reset, escapement tilting member 32 running that matches with escape wheel substrate 311.
in addition, without diagram, controlling organization can also adopt other structure, as a knob is set on timer clamping plate 1, is provided with a rippled edge on the circumferencial direction of knob, and an end of rippled edge and swinging axle 321 is inconsistent.Escape wheel sheet has how many numbers, has the projection of corresponding escape wheel sheet number on rippled edge, and the height of each projection differs, and matches with corresponding escape wheel sheet thereby control escapement tilting member 32.
embodiment bis-, as shown in accompanying drawing 10-15, embodiment bis-is with the difference of embodiment mono-, it is equally also a kind of timer conventional in prior art that example two is executed in practicality, and is a kind of without fixed frequency timer, and the profile of tooth of the tooth of escape wheel outer rim is different from the profile of tooth that has fixed frequency timer, the tooth of the escape wheel outer rim in the present embodiment is called ratchet, be escapement shape and control escapement tilting member 32, so-called steel wire escapement, and do not need escapement and the hairspring in embodiment mono-.As shown in the accompanying drawing 10,11,13 of the accompanying drawing 3,4,7 of embodiment mono-and embodiment bis-, because escape wheel substrate 311 is different from the position of escape wheel tag 312, in embodiment mono-, be that swinging axle 321 moves from top to bottom, realizing escapement tilting member 32 is changed to escape wheel tag 312 by escape wheel substrate 311, in embodiment bis-, be that swinging axle 321 moves from lower to upper, realize escape wheel parts 32 and changed to escape wheel tag 312 by escape wheel substrate 311.
as mentioned above, we are illustrated according to aim of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought license of the present utility model.
