Abstract

The utility model relates to a time talking corrector of a timepiece with a pointer mounted, which is mainly used for correcting a pointer position on an occasion of mounting the pointer. The utility model comprises a salient shifting block, a short reed and a long reed. The salient shifting block is arranged at the bottom side of a minute hand gear in a wall clock movement. The short reed and the long reed are arranged outside the salient shifting block. A notch is arranged at the top end of a propeller shaft of the minute hand gear. A fixed angle is formed between the salient shifting block and the notch. Therefore, the utility model has the advantages of simple mount, simple adjustment, low cost and high production efficiency.

Description

Time talking device with simple pointer mounted

The utility model relates to a kind of clock and watch integral point dress pin means for correcting that gives the correct time, and proofreaies and correct the integral point telling time device of pointer position when being mainly used in the dress pin.

As everyone knows, by the wall clock that gives the correct time on schedule, the minute gear bottom side in its alarm clock movement is provided with a protruding shifting block, in the protruding shifting block outside one a short reed and a long reed is set again; When minute gear rotates to protruding shifting block when touching long reed, long reed can be taken advantage of a situation and back down, and minute gear continues to rotate to an operating point, long reed is jumped out of, borrow elastic force to run into long reed, make the circuit turn-on at quarter-bell place to front curve, during the quarter-bell utmost point, when reed jumped out of protruding shifting block so will rectificate, minute hand was just in time aimed at wall clock clock face scale mark " 12 ", just meets integral point and gives the correct time.

At present, the making flow process of general wall clock, after spare parts such as wall clock movement, panel and pointer were separately made, other again luggage was joined, so when movement dispatches from the factory, need minute gear is fixed on the operating point that integral point gives the correct time frequent following two problems of appearance easily:

One, wall clock movement is before dispatching from the factory, and needs the work that do a test more, locate, and promptly utilizes instrument, and minute gear is rotated to two reeds just to be become under the situation of path and locate, adjustment formality complexity, and cost greatly improves.

Two, movement is being delivered to the assembling factory, when assembling clock face, pointer, and the gear mechanism of easy false touch movement, cause the off normal of minute gear, make wall clock can't accomplish that correct integral point gives the correct time, movement just can use after need dismantling again, assemble, adjusting, assembling inconvenience.

In view of this, the purpose of this utility model is that a kind of integral point telling time device that can simple and easy dress pin will be provided, and can make movement not need again minute gear to be tested separately, located before dispatching from the factory, no matter and the also gear of assembling clock face, pointer off normal whether, but all integral point gives the correct time.

The purpose of this utility model is achieved in that it is included in the protruding shifting block that the minute gear bottom surface in the wall clock movement is provided with and a short reed and a long reed in the protruding shifting block outside, is characterized in that: the transmission shaft top on the minute gear be provided with and protruding shifting block between a breach of formation one fixed angle.

Owing to adopt such scheme: assembling and adjustment are simple, reduce cost, and enhance productivity.

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

Fig. 1 is the schematic perspective view of the utility model embodiment.

Fig. 2 is the protruding shifting block operating position figure not of the utility model embodiment.

Fig. 3 touches long reed synoptic diagram for the protruding shifting block of the utility model embodiment.

Fig. 4 is the long and short reed contact of making of the utility model embodiment synoptic diagram.

As shown in Figure 1, (for P is installed) lateral margin is offered a breach (or protruding grain) 2 on a transmission shaft 1 top, this transmission shaft 1 extends to the minute gear 3 of concentric downwards, and minute gear 3 bottom surfaces are provided with a protruding shifting block 4, protruding shifting block 4 outsides are provided with a short reed 41 and a long reed 42 again, when minute gear 3 when rotated, as Fig. 2, shown in 3, can make protruding shifting block hold long reed 42, make the bending displacement of taking advantage of a situation of long reed 42, and protruding shifting block 4 deflects to an operating point a, as shown in Figure 4, the face that holds that long reed 42 just can break away from protruding shifting block 4 oppositely flicks, when rebounding, can contact with short reed and cause two reeds 41, the quarter-bell circuit that 42 rear ends are connected forms the path (not shown) and gives the correct time to trigger quarter-bell; When protruding shifting block 4 was rotated in the position of operating point a, breach 2 center lines were just aimed at clock face scale mark " 12 " (not shown), made and formed a fixed angle θ between breach 2 and the protruding shifting block 4; Integral point gave the correct time when the assembling minute hand per hour rotated to clock face scale mark " 12 ", to reach simply-assembled effect.

In addition, after alarm clock movement is made, run into the breach off normal that vibrations or personnel's false touch cause in the process transporting of will assembling, neither influence assembling, no matter the breach off normal is to any one position, still only needs to press the dress minute hand as stated above, can reach simply-assembled purpose; And breach system is one-body molded with protruding shifting block, minute gear and transmission shaft, and manufacturing, assembling and testing cost but can reduce, and improves the rate that comes into force.

Claims (1)

1, a kind of integral point telling time device that can simple and easy dress pin is included in the protruding shifting block that the minute gear bottom surface in the wall clock movement is provided with and a short reed and a long reed in the protruding shifting block outside, it is characterized in that: the transmission shaft top on the minute gear be provided with and protruding shifting block between a breach of formation one fixed angle.
