Abstract

The utility model discloses an automatic tracing system of a mechanical chronopher. The left part of the hour wheel tube of the existing tracing system of the mechanical chronopher is fixed with a spring, the hour wheel slice and the hour wheel tube are in the frictional integration which is realized by that the spring is pressed on the hour wheel slice. Two notches which are meshed with the lugs of the inner holes of the hour needle are opened on the other end of the hour wheel tube, making the hour needle synchronically move with the hour wheel tube. The utility model can not optionally display the time. While in the adjustment of the clock, both of the hour needle and the minute needle can be moved. The utility model has the advantages of simple structure and convenient installation.

Description

Automatic tracing system of mechanical chronopher

The utility model relates to a kind of improved follower that gives the correct time, particularly a kind of mechanical striking clock automatic tracking mechanism that gives the correct time that is applicable to.

The existing mechanical follower that gives the correct time, mainly be on hour wheel pipe fixedly hour wheel sheet, 12 angular cams, the time needle tubing, the time hour hands are arranged on the needle tubing.This mechanism is owing to relatively rotate easily between hour hands and the hour wheel pipe, when time signal clock is shaken or extraneous factor such as collision influences, give the correct time and to upset a little, the hour wheel of existing mechanical time signal clock and branch wheel construction, time signal clock can only be stirred minute hand to constantly, drives hour wheel with minute wheel and rotates, and can not stir hour hands, cause inconvenience.

Task of the present utility model just provides a kind of improved automatic tracking mechanism that gives the correct time, and it can overcome to give the correct time upsets a phenomenon, to constantly, both can stir minute hand, can stir hour hands again, makes things convenient for the user.

Task of the present utility model is finished like this: with between the hour wheel sheet of former follower and the hour wheel pipe by fixedlying connected the flexible connection that changes clearance fit into, fix a spring at the hour wheel pipe left end, this spring compression hour wheel sheet, make hour wheel sheet and hour wheel pipe become frictional engagement, normally walk constantly, the hour wheel sheet is under the effect of spring friction force, with hour wheel pipe, 12 angular cams, spring unitary rotation.Relative position has two notches on the same center line in hour wheel pipe right side, hour hands and the time needle tubing be assembled into integral body, its endoporus has two projections, hour hands endoporus projection is pressed in the hour wheel pipe notch, projection is meshed with the hour wheel pipe notch, like this, can not relatively rotate between hour hands and the hour wheel pipe, after time signal clock is shaken or collides, give the correct time and just can not upset a little.When stirring hour hands, time needle tubing, hour wheel pipe, 12 angular cams of hour hands and its one can rotate synchronously, and promptly 12 angular cams are followed the tracks of hour hands all the time, and the hour wheel sheet is motionless.Need both minute hand can be stirred to constantly, also hour hands can be stirred.Entire mechanism only increases a spring, and the slight change of individual part structure is constructed very simple.

Below with reference to drawings and Examples the utility model is described in detail.

Fig. 7 is the right view of Fig. 6.

Embodiment 1: with reference to Fig. 1, Fig. 2, hour wheel pipe (3) left end after a kind of improve has the hour wheel sheet (1) of clearance fit with it, and with existing follower same position on fix 12 angular cams (4) needle tubing (6) in time, the time needle tubing (6) be assembled into integral body with hour hands (5).Fix a spring leaf (2) at hour wheel pipe (3) left end, spring leaf (2) the hour wheel sheet (1) that is fixed and clamped makes the moment of friction of its generation, is normally walking constantly, can drive hour wheel pipe, 12 angular cams unitary rotation.To the time when stirring hour hands (5), hour wheel pipe (3), the time needle tubing (6), 12 angular cams (4) rotate synchronously, and hour wheel sheet (1) is motionless, for reaching this purpose, relative position has two notches (7) on the same center line in hour wheel pipe (3) right side, the width of notch is 1.1～2.1 millimeters, and present embodiment gets 1.3 ^{+ 0.06}Millimeter.Hour hands (5) with the time needle tubing (6) be assembled into integral body, its endoporus has two projections (8), its bump width is 1～2 millimeter, present embodiment gets 1.2

Millimeter.Hour hands endoporus projection (8) is packed in the hour wheel pipe notch (7), can reach between hour hands (5) and the hour wheel pipe (3) and not relatively rotate, time signal clock just can not upset a little when being shaken or collide, and 12 angular cams (4) are followed the tracks of hour hands (5) all the time.The utility model task is finished.

Embodiment 2: be the identical another kind of the principle automatic tracking mechanism that gives the correct time with reference to Fig. 5.This mechanism makes the spring leaf (2) of embodiment 1 into compression spring, and the structure of hour wheel pipe (3) has change slightly, and all the other structures are with embodiment 1, and just this structure is not as embodiment 1 compactness, hour wheel pipe material consumption multiple spot.

Claims

1, a kind of mechanical striking clock automatic tracking mechanism that gives the correct time, be by hour wheel sheet (1), hour wheel pipe (3), 12 angular cams (4), hour hands (5), the time needle tubing (6) form, it is characterized in that being between hour wheel sheet (1) and the hour wheel pipe (3) clearance fit, fix a spring (2) at hour wheel pipe (3) left end, this spring (2) compresses hour wheel sheet (1), relative position has two notches (7) on the same center line in hour wheel pipe right side, hour hands (5) with the time needle tubing (6) be assembled into integral body, the endoporus of hour hands (5) has two projections (8), and hour hands endoporus projection (8) is pressed in the hour wheel pipe notch (7).

2, by the described automatic tracking mechanism that gives the correct time of claim 1, the width that it is characterized in that hour hands endoporus projection (8) is 1～2 millimeter, and the width of hour wheel pipe notch (8) is 1.1～2.1 millimeters.
