Abstract

A clock time recognizing and reading disk capable of improving the learning capability of clock recognizing and reading consists of a shell box, a face disk, a rotary disk and a gear. The shell box is fixedly arranged with the back of the face disk; the center of the rotary disk is provided with a rotating shaft which is connected with the shell box through a central hole of the face disk; the rotating shaft of the rotary disk is provided with a minute hand gear and a hour hand gear in a penetrating way; the rotating shaft is fixedly connected with the minute hand gear and movably connected with the hour hand gear; the shell box is internally provided with a combined transition gear formed by superimposing two transition gears; and the two superimposed transition gears on the combined transition gear are respectively occluded with the minute hand gear and the hour hand gear to form a complete hour hand and minute hand linkage system which is the same as a real clock. By improving the shortcoming of the previous time recognizing and reading disk that the minute hand and the hour hand can not be linked, the clock time recognizing and reading disk is more convenient, vivid and intuitive for children to learn time recognizing and reading.

Description

Watch time recognize read the dish

Technical field

The utility model relates to the time and recognizes the teaching tool of reading, and particularly relates to a kind of watch time and recognizes and read dish.

Background technology

At present, relevant watch time is recognized the teaching of reading in China primary school one, the second grade mathematics course, and in most stages that also rest on oral teaching, the condition of teaching and means are shortcoming, has hindered the student to recognize to read watch time and to the study of watch time knowledge.Although also there are many parentss of student can be by teacher's requirement, do it yourself to make or recognize and read dish buying easy watch time on the market, all because the hour hands minute hand can not link, and brought problem in many understandings for the children of study.

Summary of the invention

Recognize and read the problems referred to above that the teaching aspect exists in order to overcome present primary school clock and watch, the purpose of this utility model provides a kind of watch time that can link and recognizes and read dish.

The utility model is taked following technical scheme, a kind of watch time recognize read the dish, it is by the shell box, face, rotating disk and gear are formed, the back side fixed installation of shell box and face, there is a rotating shaft at the center of rotating disk, rotating shaft is connected with the shell box by the center pit of face, be installed with minute gear and hour hand gear in the rotating shaft of rotating disk, rotating shaft is fixedlyed connected with minute gear, rotating shaft and hour hand gear flexibly connect, the combination transition gear is housed in the shell box, and the combination transition gear is formed by stacking by two transition gears, two registration sprocketed wheels of combination on the transition gear respectively with minute gear and hour hand gear interlock; Be fixedly connected with the minute hand pointer on the described minute gear, be fixedly connected with the hour hands pointer on the hour hand gear; The positive peripheral equal distribution ground mark of described face has 12 time scales; Described minute hand pointer mint-mark or stick on the rotating disk; Described combination transition gear can be bonding by two and web gear same axle center form.

The beneficial effects of the utility model are, clock and watch hour hands and minute hand can link, easy to use, it is a kind of effective teaching tool, for the students of study watch time knowledge provide one truly, schooling apparatus intuitively, can also provide one to recognize the toy of teaching through lively activities of reading watch time for the preschool child.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structure partial diagrammatic cross-section of the present utility model.

Fig. 2 is that A-A of the present utility model is to diagrammatic cross-section.

Fig. 3 is the structure partial diagrammatic cross-section of another embodiment of the present utility model.

1. shell boxes among the figure, 2. minute hand pointer, 21. hour hands pointers, 3. hour hand gear, 4. minute gear, 5. rotating disk, 51. rotating shafts, 6. combination transition gear, 7. face, 8. hour hands rotating disk, 9. minute hand rotating disk

Embodiment

See figures.1.and.2, watch time recognize read the dish by shell box 1, face 7, rotating disk 5 and gear are formed, shell box 1 fixedly mounts with the back side of face 7, there is a rotating shaft 51 at the center of rotating disk 5, rotating shaft 51 is connected with shell box 1 by the center pit of face 7, be installed with minute gear 4 and hour hand gear 3 in the rotating shaft 51 of rotating disk 5, rotating shaft 51 is fixedlyed connected with minute gear 4, rotating shaft 51 flexibly connects with hour hand gear 3, combination transition gear 6 is housed in the shell box 1, combination transition gear 6 is formed by stacking by two transition gears, two registration sprocketed wheels of combination on the transition gear 6 respectively with minute gear 4 and hour hand gear 3 interlocks; Be fixedly connected with rotating disk 5 and minute hand pointer 2 on the minute gear 4, be fixedly connected with hour hands pointer 21 on the hour hand gear 3; The positive periphery of face 7 scale when all the five equilibrium ground mark has 60 scale divisions and 12; Minute hand pointer 2 can mint-mark or is sticked on the rotating disk 5; Combination transition gear 6 can be bonding by two and web gear same axle center form.When people rotated rotating disk 5 with hand, the minute gear 4 transmission combination transition gears of fixing in the rotating shaft 51 6, combination transition gear 6 were again with transmission hour hand gear 3, thereby drive hour hands 2 rotate and finish the interlock of emulation clock and watch, and rotating disk 5 adopts the transparent material making.

Another embodiment of the present utility model is, watch time recognize read the dish by shell box 1, face 7, rotating disk 5 and gear are formed, shell box 1 fixedly mounts with the back side of face 7, there is a rotating shaft 51 at the center of rotating disk 5, be installed with minute gear 4 and hour hand gear 3 in the rotating shaft 51 of rotating disk 5, rotating shaft 51 is fixedlyed connected with hour hand gear 3, rotating shaft 51 flexibly connects with minute gear 4, when people rotate rotating disk 5 with hand, the hour hand gear 3 transmission combination transition gears of fixing in the rotating shaft 51 6, combination transition gear 6 is again with transmission minute gear 4, thereby drive minute hand 2 rotates and finish the interlock of emulation clock and watch.

With reference to Fig. 3 and Fig. 4, the utility model also has an embodiment, hour hands pointer 21 can adopt the disc type pointer structure respectively with minute hand pointer 2, when adopting the disc type pointer structure, pointer pattern is marking on 9 of hour hands rotating disk 8 and minute hand rotating disks, hour hands rotating disk 8 is littler than minute hand rotating disk 9, so when using, only need to rotate the effect that hour hands rotating disk 8 or minute hand rotating disk 9 can reach the emulation clock and watch; The form that also can adopt disc type to combine with pointer-type, promptly hour hands adopt disc type, and minute hand adopts pointer-type, or both are opposite.

The utility model has changed the time in the past to be recognized and reads to coil the shortcoming that minute hand and hour hands can not link, more convenient when making children learn to recognize read time, true to nature and directly perceived.
