Abstract
The utility model relates to minute hand and hour hand structure for a movement of a radio wave clock, which comprises a minute hand, an hour hand and hand shafts which are used for installing the minute hand and the hour hand, wherein mounting holes of the shank of the minute hand and the hour hand are polygon holes, and the cross sections of the minute hand shaft and the hour hand shaft are polygons which are matched with the mounting holes of the minute hand and the hour hand mounted on the minute hand shaft and the hour hand shaft to make directional transition fit. After mounted, the mounting holes of the minute hand and the hour hand do not rotate correspondingly with the hand shafts. Thus, the utility model can improve the initial precision of the radio wave clock assembling, and ensures operating precision.
Description
Technical field
The utility model relates to radio wave clock, particularly the radio wave clock movement.
Background technology
The minute hand of existing radio wave clock movement, the time needle construction, comprise minute hand, hour hands and for the needle shaft that minute hand, hour hands are installed.The mounting hole of minute hand, hour hands shank is circular, minute hand shaft, hour hand axle are for matching matched cylindrical with it, its weak point is: circular port matches with cylindrical shaft, (along the relative motion of circumference) can relatively rotate, will influence initial precision of assembling (as 12 o'clock high noons, minute hand, hour hands were simultaneously over against " 12 " word) and running precision like this.For solving above-mentioned deficiency, the producer that has is processed as screw with the mounting hole of pointer shank, needle shaft is processed as screw rod and pointer shank screw revolves and join, but still be not enough to address the above problem, if the pin group is swung by external force, still relatively rotating of screw and screw rod can be taken place.
Summary of the invention
The technical matters that will solve of the present utility model be overcome above-mentioned weak point and provide a kind of novel radio wave clock movement minute hand, the time needle construction, the mounting hole of pointer shank is a polygon, needle shaft also is a polygon correspondingly, making directionality cooperates, can guarantee not relatively rotate between them, assemble initial precision and guarantee running precision and improve radio wave clock.
The utility model adopts following technical scheme:
A kind of minute hand of radio wave clock movement, the time needle construction, the needle shaft that comprises minute hand, hour hands and confession installation minute hand, hour hands, the mounting hole of minute hand, hour hands shank is a polygonal hole, the polygon of the xsect of minute hand shaft, hour hand axle for cooperating with the minute hand that is installed on it, hour hands mounting hole.Minute hand can be polygon inequality or identical polygon with the mounting hole of hour hands, and they are any in the shape hole, 2-9 limit.The mounting hole of minute hand, hour hands shank and preferred transition fit of cooperating of needle shaft.
Advantage of the present utility model is: because the mounting hole of minute hand, hour hands is a polygon, the needle shaft xsect of installing for minute hand, hour hands is the polygon that pairing with it cooperates, make the directionality transition fit, do not relatively rotate after the installation, can improve radio wave clock and assemble initial precision and guarantee running precision.
