Abstract

The utility model discloses a time adjustment mechanism in a clock. The time adjustment mechanism comprises a manual time adjustment button arranged on the back of a movement in a clock shell, a manual time adjustment rod and an outer manual time adjustment button, wherein the outer manual time adjustment button is arranged at one end of the manual time adjustment rod and linked with the rotation direction of the manual time adjustment rod; the manual time adjustment rod extends from the clock shell into the movement in the clock shell; a small conical tooth is formed at one end of the manual time adjustment rod, which extends to the movement; and the small conical tooth and a large conical tooth formed on the manual time adjustment button form a meshed structure. The manual time adjustment rod extends out of the shell from the movement in the clock shell, and the outer manual time adjustment button is arranged outside the clock shell, so that time can be adjusted by rotating the outer manual time adjustment button from the side surface during time adjustment; and at the moment, a user can observe the position of a minute hand while rotating the outer manual time adjustment button for time adjustment.

Description

Time adjusting mechanism in a kind of clock

Technical field

The utility model relates to clock and watch and makes the field, particularly is used for adjusting the time adjusting mechanism of demonstration time elimination error when error is arranged when clock shows time and real time.

Background technology

The critical piece of clock and watch is that movement is as shown in Figure 1; Movement 1 drives the speed rotation according to the rules of hour hands 2, minute hand 3 and second hand (second hand does not draw in the drawings); Scale is set on dial plate, and these scales combine hour hands, minute hand and second hand real time position, show real-time time.Sometimes owing to some reasons, the time of demonstration has error need adjust hour hands, minute hand and second hand real time position with the real time.According to the structure of clock and watch hour hands, minute hand and second hand moved in coaxial, hour hands are with the minute hand rotation, and second hand and hour hands, minute hand rotation are relatively independent, and therefore, the adjustment time generally is that accomplish the residing position of adjustment minute hand at present.At present, the time adjustment is to accomplish through the manual timing button 4 that is rotatably provided in the movement back side, observes dial plate during adjustment, through the manual timing button 4 of rotation movement 1 back, and deadline adjustment when minute hand 3 rotates to the precalculated position.This adjustment time method is intuitively simple, is the adjustment time method that present horological industry generally adopts.But, for the bigger clock of dial plate, when seeing dial plate sometimes; Hand can not reach manual timing button 4 places on the movement 1 that is arranged on center, the dial plate back side; Perhaps to unload whole great bell from wall, need the adjustment time, sometimes even can not accomplish by a people with cumbersome.

Summary of the invention

The utility model is in order accurately to adjust the time and to have designed a kind of time adjusting mechanism the bigger clock of dial plate.

The utility model is that the technical scheme that its goal of the invention of realization is adopted is; Time adjusting mechanism in a kind of clock; Comprise the manual timing button that is arranged on the movement back side in the clock shell, also comprise manual timing bar and the outer tuning knob of manual timing, the outer tuning knob of described manual timing is arranged on an end of manual timing bar; With described manual timing bar sense of rotation interlock; Described manual timing bar stretches to the movement that is arranged in the clock shell from the clock shell, and an end that stretches to the movement place at described manual timing bar is provided with the conelet tooth, but described conelet tooth is formed joggled structure with the auger tooth that is arranged on the described manual timing button.

Further, in above-mentioned a kind of clock in the time adjusting mechanism: on described manual timing bar, be with retracing spring, described retracing spring is arranged between outer tuning knob of described manual timing and the clock side wall of outer shell.

Further, in above-mentioned a kind of clock in the time adjusting mechanism: be provided with the stop collar that the described manual timing bar of restriction radially wobbles in described movement side.

Further, in above-mentioned a kind of clock in the time adjusting mechanism: described clock side wall of outer shell is provided with the fixed cover of fixing described manual timing bar.

Further, in above-mentioned a kind of clock in the time adjusting mechanism: described fixed cover is arranged on the described clock shell madial wall.

The utility model stretches out shell owing to be provided with manual timing bar movement in the clock shell; And be provided with the outer tuning knob of manual timing outside; When timing, can rotate the outer tuning knob deadline adjustment of manual timing from the side, at this moment; The position of simultaneously can the limit observing minute, the limit rotates the outer tuning knob deadline adjustment of manual timing.

Below in conjunction with accompanying drawing and embodiment the utility model is at length explained.

Description of drawings

Fig. 1 is present movement schematic rear view.

Fig. 3 is the time adjusting mechanism structural representation (big conelet tooth engagement) of the utility model.

Among the figure: 1, movement, 2, hour hands, 3, minute hand, 4, manual timing button, 5, the auger tooth, 6, the conelet tooth, 7, manual timing bar, 8, retracing spring, 9, the manual outer tuning knob of timing, 10, fixed cover, 11, stop collar, 12, the clock shell.

Embodiment

The utility model is the time adjusting mechanism of adjustment time on a kind of more large-scale clock, and like Fig. 2, shown in Figure 3, this mechanism is arranged on the clock; Comprise the manual timing button 4 that is arranged on movement 1 back side in the clock shell 12; Manually timing bar 7 and the manually outer tuning knob 9 of timing, wherein, manually the outer tuning knob 9 of timing is arranged on an end of manual timing bar 7; With manual timing bar 7 sense of rotation interlocks; Manually timing bar 7 stretches to the movement 1 that is arranged in the clock shell 12 from clock shell 12, and an end that stretches to movement 1 place at manual timing bar 7 is provided with conelet tooth 6, but conelet tooth 6 is formed joggled structure with the auger tooth 5 that is arranged on the manual timing button 4.When being meshing with each other, drive 4 rotations of original manual timing button through rotating the outer tuning knob 9 of manual timing, accomplish minute hand 3 adjustment then.In the present embodiment, carry out when adjustment time, conelet produces engagement in company with manual timing bar 7 near the auger tooth each other manually axially pushing down manual timing button 9; But the time of not carrying out when also being operate as normal, generally needs large and small awl tooth to be separated from each other when adjusting; Therefore, manually be with retracing spring 8 on the timing bar 7, retracing spring 8 is arranged between outer tuning knob 9 of manual timing and clock shell 12 sidewalls; Timing is accomplished, after staff leaves tuning knob, under the effect of retracing spring; Conelet tooth 6 leaves the auger tooth together with the timing bar, reduces the transmission resistance of newly-increased time-setting mechanism to movement.

Large and small awl tooth is separated from each other, reduces the transmission resistance of newly-increased time-setting mechanism movement.Because in a bigger clock; The distance of the movement 1 from clock shell 12 sidewalls to central authorities is bigger, needs long manual timing bar 7, therefore; Also need fix manual timing bar 7; It is fixing that fixed manual timing bar 7 is heard end from two, at first is provided with stop collar 11 that limit manual timing bar 7 radially wobbles in movement 1 side and prevents that manual timing bar 7 from swinging inside, then at clock shell 12 sidewalls; Realize that for time-setting mechanism the timing function is steadily reliable, clock shell 12 madial walls are provided with the fixed cover 10 of fixed manual timing bar 7.
