Description

Technical Field

[0001] The utility model relates to the field of electronic clocks and watches, in particular to a positive electrode sheet of an electronic clock movement and a stop-second mechanism of the electronic clock and watch. Background Art

[0002] In 1955, Switzerland successfully developed the first electronic watch with a hairspring. Since then, the watch industry has entered the electronic age, breaking the stable pattern of mechanical watches that lasted for about 200 years. It has freed watches from the category of pure "precision machinery", thus causing rapid and profound changes in the watch industry. In just over 20 years, it has developed to the fourth generation, and the output has been soaring. Watches containing electronic circuits can be divided into balance wheel electronic watches, tuning fork watches and quartz watches according to the different vibration systems or oscillators used. They are also called electronic watches.

[0003] In the field of watches, the stop seconds and running time are basically achieved by the separation and contact of the clutch rod and the stop seconds end. The positive electrode of the electronic watch movement and the stop seconds mechanism of the electronic watch are both important structures of the electronic watch.

[0004] The existing electronic watch movement and stop-second mechanism are not ideal, which may reduce the adaptability of the device. The existing electronic watch is not easy to be disassembled and assembled conveniently, which may reduce the maintenance efficiency of the user.

[0005] Therefore, in view of the above problems, a positive electrode sheet of an electronic watch movement and a stop-second mechanism of an electronic watch are proposed. Utility Model Content

[0006] In order to remedy the problems in the prior art, the utility model provides a positive electrode sheet of an electronic clock movement and a stop-second mechanism of an electronic clock.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the positive electrode sheet of an electronic clock movement and the electronic clock stop second mechanism described in the utility model include a base plate, a first positive electrode sheet and a second positive electrode sheet are fixedly installed on the surface of the base plate, a plurality of circular positioning holes are provided on the surface of the plate-like main body of the first positive electrode sheet, a connecting rod and an elastic claw are fixedly connected to one side of the first positive electrode sheet, and a card slot is fixedly connected to the surface of the first positive electrode sheet.

[0008] Preferably, the connecting rod is always in contact with the clutch, and the elastic claw is connected to the positive input terminal of the circuit board.

[0009] Preferably, a plurality of circular positioning holes are provided on the surface of the plate-shaped main body of the second positive electrode sheet, an elastic hook and an elastic rod are provided on one side of the second positive electrode sheet, and a through hole is opened on the surface of the elastic rod.

[0010] Preferably, a clamping block is fixedly connected to the top surface of the bottom plate, and the clamping block is in an L-shape.

[0011] Preferably, a top cover is fixedly installed above the bottom plate, and a sliding groove is provided on the surface of the top cover.

[0012] Preferably, the number of the slide grooves is two, and the two slide grooves are centrally symmetrically distributed with the vertical center line of the top cover as the midpoint.

[0013] The utility model is beneficial in that:

[0014] 1. The utility model is that when the time-adjusting stem is pushed in and in the running state, the time-adjusting stem is connected with the clutch, the positive electrode of the battery power is transmitted from the second positive electrode sheet to the clutch via the time-adjusting stem, and then transmitted from the clutch to the first positive electrode sheet and the connecting rod, and then transmitted to the positive electrode input end of the circuit board via the elastic claw. When the time-adjusting stem is pulled out and in the time-adjusting gear, the stem is disengaged from the clutch. At this time, the positive electrode of the second positive electrode sheet power cannot be introduced into the first positive electrode sheet and the circuit board by the stem, and the positive electrode of the power is in a disconnected state, so the circuit board cannot work, that is, it stops running, which is convenient for controlling the working switch of the device and improves the adaptability of the device;

[0015] 2. The utility model squeezes the card block at the opening of the slide slot and then rotates the top cover to make the card block slide in the slide slot and then detach. After the maintenance is completed, the slide slot is aligned with the inclined surface of the card block to squeeze the card block inward, and the top cover is rotated to a suitable position. The card block automatically aligns with the opening of the slide slot, which is convenient for disassembling and assembling the top cover for maintenance, thereby improving the work efficiency of the user.
