Description

Clock and watch hands and indicator

The pointer of the utility model---a kind of clock and watch and indicating device belong to the pointer of mankind life article's clock and watch and the improvement of indicating mechanism.

Present all pointer clocks, its hand train wheel all are that axle second with the second wheel assembly is the center, put branch wheel assembly and hour wheel module outside successively, are connected with driving pulley assembly by crossing wheel assembly again.Its indicating device comprises the clock dial with center pit, second axle and cannon pinion, hour wheel pipe all pass the center pit of clock dial, the second hand gland on the second axle and with axle wringing fit second, the minute hand gland is on cannon pinion, the hour hands gland on hour wheel pipe, and respectively with cannon pinion, hour wheel pipe wringing fit, thereby utilize gear drive drive second, branch, the time pointer carry out a kind of mowing type circumference rotation of dullness, make the indication of clock and watch seem dull stiff, lack attractive force.

The purpose of this utility model is exactly in order to overcome the above-mentioned shortcoming of existing clock and watch, a kind of pointer and indicating device of novelty to be provided, and makes the clock and watch not only can be as time display, can also be simultaneously as handicraft, ornament.

The utility model is that the different hand train wheels by particular design, different pointer and indicating mechanisms realize.Following elder generation describes Figure of description, describes invention main points of the present utility model then in conjunction with the accompanying drawings.Fig. 1 is the pointer of clock and watch and the drive mechanism figure of indicating device, and among the figure: 1 is clock dial; 2 is hour hands; 3 is minute hand; 4 is second hand; 5 is second wheel pipe (axle); 6 is second wheel; 7 is second wheel tooth axle; 8 is cannon pinion (axle); 9 for dividing third wheel; 10 for dividing gear teeth axle; 11 is power wheel; 12 is minute wheel; 13 are transmission gear teeth axle; 14 is minutepinion; 15 is hour wheel; 16 wheel shafts (pipe) when being.Fig. 2 is a pointer array mode structural drawing, and among the figure: 2 is hour hands; 3 is minute hand; 4 is second hand; 5 is second wheel pipe (axle); 8 is cannon pinion (axle); 16 is hour wheel pipe (axle).Fig. 3 is the drive mechanism figure of many second hands (three second hands), and among the figure: 2 is hour hands; 3 is minute hand; 4 is second hand; 6 is second wheel; 7 is second wheel tooth axle; 17 is the power wheel between second wheel.Fig. 4 is the clock face three-view diagram, and wherein (A) is front elevation, (B) is vertical view; (C) be left view, among the figure: 18 is support; 19 is clock face glass; 20 is shell; 21 is the first clock dial assembly; 22 is first track; 23 is the second clock dial assembly; 24 is second track; 25 is the 3rd clock dial assembly; 26 is the 3rd track; 27 is the 4th clock dial assembly.Fig. 5 is the pointer structure view, wherein: (D) for being with the pointer structure three-view diagram of slide block; (E) be hinge connected mode pointer structure view, among the figure: 28 is needle pivot; 29 is slide block; 30 is follower lever.

Invention main points of the present utility model are: (1) as shown in Figure 1, adopting the time wheel shaft 16 of

hour wheel module

15,16 is the center, put the structure of cannon pinion 8 and second wheel pipe 5 successively, having replaced the second wheel axle of the existing second wheel assembly of using always 5,6,7 is the center, puts the structure of cannon pinion 8 and hour wheel pipe more successively.Its transmission process is: the second wheel 6 that promoted by train, driving the second hand 4 of gland on second wheel pipe 5 by second wheel pipe 5 rotates, second wheel tooth axle 7 promotes power wheel 11 simultaneously and rotates, promote minute wheels 12 by transmission gear teeth axle 13 again and rotate and drive minute hand 3 operations of gland on cannon pinion 8, minutepinion 14 promote to divide third wheels 9 again by divided gear teeth axle 10 to promote hour wheels 15 and drive gland the time hour hands 2 on the wheel shaft 16 rotate; (2) adopt sectional type clock dial modular construction as shown in Figure 4, and utilize the combinational gap of clock dial assembly 21,23,25,27 to form the track 22,24,26 that offers the pointer operation.As required, available 2～9 clock dial assemblies are formed 1～8 track, and trade shape can be various closed curves, and each pointer is subjected to the constraint of track, and move by the track of various track regulations.Each clock dial assembly is fixedlyed connected with clock face glass 19, shell 20 by support 18; (3) the utility model can adopt the second wheel and the second hand of 1～5 identical or different rotating speed; (4) the utility model places part pointer or whole pointer under the various dish assemblies, and place the pointer under the clock dial just partly to expose outside the clock dial, and can adopt as shown in Figure 5 two kinds of novel pointer structures, a kind ofly constitute by needle pivot 28 and the slide block 29 that can on needle pivot 28, be free to slide, the absolute motion on slide block 29 tops is synthetic by convected motion (being the rotation of needle pivot 28), relative motion (being the rectilinear motion of slide block 29 on needle pivot 28), so it can be by the arbitrary plane curve motion; Another kind is to be made of needle pivot 28 and follower lever 30, be connected by the hinge connected mode between needle pivot 28 and the follower lever 30, the absolute motion on follower lever 30 tops is synthetic by convected motion (being the rotation of needle pivot 28), relative motion (being the rotation of follower lever 30), and it also can be by the arbitrary plane curve motion; Simultaneously, pointer also adopts the pin cap, the pin cap can directly form with needle pivot 28, slide block 29 tops or follower lever 30 bendings, also can be connected to form by other lightweight pin cap and above-mentioned needle pivot 28, slide block 29 or follower lever 30, if the pin cap is made and is had elasticity or mobilizable, then can stretch up and down, then the track of pin cap just can be the space closed curve of fluctuating.

Compare with existing clock and watch, owing to the utlity model has brand-new pointer wheel structure, clock dial modular construction, pointer and pin cap, dull stiff unappealing shortcoming seems thereby the pointer that has overcome existing clock and watch has only a kind of mowing type circular motion of dullness, make clock and watch have the tracks of the full of flourishes and curvilinear figure of all kinds of pointer, thereby seem novelty attractive in appearance, can not only be as time display, and can come decorative environment as handicraft simultaneously, improve the value and the practicality of clock and watch.

The inventor once improved assembling according to structure technology scheme of the present utility model to an old crystal clock, and the utility model is implemented substantially.At first, be cut into the oval clock dial assembly of four different sizes with flake aluminum, select the nested unitized construction of tubular axis simultaneously for use---promptly managing 5 nested cannon pinions 8 second when being nested in again on the wheel shaft 16, by shown in Figure 4, the clock dial assembly that shears by support (doing support) and clock face glass with elongate threaded screw, shell is fixedly connected, and form three tracks, again by reorganization point gear shown in Figure 1, and the pointer bending stretched out as the pin cap by track, simultaneously that the second wheel of the ratio wheel of crystal clock and point gear is meshing, utilize the original expulsive force of crystal clock to drive pointer in the formed orbital motion of clock dial.
