Abstract

The utility model relates to a double-face quartz clock which comprises a quartz oscillating part, a clamping plate, a wheel shaft, gears, a dial, a clock case and indicating needles. The utility model is characterized in that back face time indicating and traveling systems are symmetrically arranged on a back face time indicating and traveling system and a front face time indicating and traveling system of a time traveling machine core of the existing quartz clock; the dynamic force of the time traveling machine core is transmitted to the back face time indicating and traveling systems through a driven gear, a back face time indicating driving gear and an inversion gear. The utility model uses one machine core to realize double-face time indication, with the advantages of small machine core size, material saving and low cost. The utility model is suitable for public places, such as offices, station waiting rooms, halls, airports, docks, etc.

Description

Double face quartz clock

Crystal clock when the utility model relates to a kind of two-sided finger contains quartz oscillation part, clamping plate, wheel shaft, gear, clock face, clock shell, clock pin.

Public arena in the many cities of China, as the hotel, the station, harbour, turret clock when all having multiaspect to refer on the City Building, but be the mechanical type turret clock mostly, this mechanical type turret clock must have a master clock movement, and several times just should have several secondary clock movements when referring to mutually, and the contour dimension of each movement is big, weight is heavier, inconvenience is installed and maintenance, a kind of " quartz clock controlled simulation synchronous AC turret clock " disclosed in Chinese patent 88209004.6, be to make master clock, drive the turret clock secondary clock, the synchronous operated simple and easy turret clock of simulation master clock pointer with the control alternating current generator with the common music quartz clock movement that gives the correct time, the clock of this structure is still and adopts a plurality of movements, contour dimension is big, and the cost height still can not generally be promoted the use of.

The purpose of this utility model is to provide a kind of unit core for fear of above-mentioned the deficiencies in the prior art part, crystal clock during extra-thin two-sided finger.

The purpose of this utility model realizes by following measure:

Crystal clock during a kind of two-sided finger, contain the quartz oscillation part, clamping plate, wheel shaft, gear, clock face, the clock shell, the clock pin, last, wheel shaft is housed between the lower plate, partly producing torque by quartz oscillation rotates rotor banding axis of a movable block I, be delivered to the branch mid-wheel drive wheel and the minute wheel of minute wheel pivot by two idle wheels on two idle wheels on runner on the wheel shaft I and the wheel shaft II and the wheel shaft III and two idle wheels on the wheel shaft IV, then through big, little hour wheel on wheel shaft when wheel is delivered to, partly constitute quartz clock movement by these gear drives, travel time system when the reverse side of quartz clock movement has the symmetrical reverse side of travel time system when referring to the quartz clock movement front to refer to contains big, little to wheel be installed in the minute wheel on the minute wheel pivot and the hour wheel on the wheel shaft when being installed in; The and greatly follower gear on wheel and the wheel shaft V being meshed of the travel time system the when front of crystal clock refers to; Driving gear when reverse side also being installed on wheel shaft V referring to, when reverse side refers to driving gear with swing to gearing mesh, swing to greatly wheel being meshed of the travel time system of gear when referring to, thereby the travel time system when driving reverse side and referring to turns round with reverse side.

The purpose of this utility model can also realize by following measure:

When two-sided finger, be equipped with on the wheel shaft V of crystal clock transmission wheel and with the engagement of manual transmission wheel, thereby by manual driving lever stir transmission wheel realize to the time, timing.

The utility model has following advantage compared to existing technology:

1, this crystal clock utilizes original quartz clock movement, and only than the thick 2mm of contour dimension of the movement of single face crystal clock, the thickness of general shape size is less than general turret clock;

2, this crystal clock adopts a movement, and two-sided indication can be saved material, and cost is low;

3, this crystal clock uses battery, 1 year about batteries, power saving, punctual timing used.

Concrete structure of the present utility model is provided by the following drawings:

The utility model is also incited somebody to action in conjunction with the accompanying drawings, and 1,2 embodiment are described in further detail:

With reference to Fig. 1,2, structure of the present utility model is between upper and lower clamping plate (17,3) wheel shaft I, II, III, IV, V to be housed, and gear is installed on wheel shaft, movement when forming the walking of crystal clock, and the number of teeth of the gear of movement is the standard number of teeth when walking; The number of teeth of the minute wheel (12,12 ') of corresponding crystal clock travel time system is 15, the number of teeth of hour wheel (13,13 ') is 48, the number of teeth to wheel (15,15 ') is 45 greatly, the little number of teeth to wheel (14,14 ') is 12, the number of teeth of follower gear is 15, the number of teeth of driving gear when reverse side refers to (16 ') is 15, it is indefinite to swing to gear (5) and transmission wheel (18, the 18 ') number of teeth, but for the purpose of reducing the one-piece construction size, should select the number of teeth for use is about 15, and these gears all form through Precision Machining; During installation, rotor (1) and runner (2) are installed on the wheel shaft I, and on the wheel shaft II, be installed with idle wheel (4,6), on the wheel shaft III, be installed with idle wheel (7,8), on the wheel shaft IV, be installed with idle wheel (9,10), these idle wheels mesh mutually, branch mid-wheel drive wheel (11) and idle wheel (10) engagement are installed on minute wheel pivot again, minute wheel (12) is installed on the minute wheel pivot with the branch mid-wheel drive wheel is coaxial, minute wheel (12) with greatly to the wheel (15) engagement, greatly, little of wheel (15,14) coaxial installation, little to wheel (14) and to wheel (13) engagement, then, greatly to wheel (15) again with wheel shaft V on follower gear (16) engagement, the travel time system symmetry was big when the reverse side of movement was equipped with positive the finger when crystal clock is walked, little to the wheel (15 ', 14 '), minute wheel (12 '), hour wheel (13 '); Wheel shaft V goes up and follower gear (16) is symmetrically installed with reverse side driving gear (16 ') when referring to, driving gear (16 ') with swing to gear (5) engagement, swing to gear (5) when referring to reverse side again travel time system greatly to wheel (15 ') engagement, greatly wheel (15 ') is meshed with minute wheel (12 ') again, by little wheel (14 ') and hour wheel (13 ') are meshed, come transferring power, and transmission wheel (18) is housed on wheel shaft V and meshes with manual transmission wheel (18 '), by driving lever stir transmission wheel come to the time, timing; And then the mounted movement clock shell of packing into, the time load onto hour hands, minute hand respectively on wheel shaft and the minute wheel pivot, require the indication of tow sides clock pin identical, adorn clock face then, clock face can be made of aluminium sheet or iron sheet.The length of the monnolithic case size of this clock is 60cm, high 54cm, and the thickness minimum dimension can reach 3.4cm, and whole crystal clock volume is little, in light weight, and installation and maintenance are convenient.
