The present invention relates to a bird movement device of a bird sound clock, in order to operate the bird body coupled with the clock to align the weft worm of the motor to the driven spur gear which is rotated separately from the upper part of the driven spur gear, driven spur gear The driven spur gear rotates by frictional force of the spring as the forward and reverse rotation of the motor is interposed between the spur gear and the spur gear, and the rack part of the support plate for the forward and backward movement of the new body on the driven spur gear While the interlocking is focused on the forward and backward operation of the support plate for the forward and backward movement is made,

In the operation of the bird body due to the deformation of the mechanism or the structure of the operation mechanism of the conventional bird's watch, the noise of the opening and closing door is unstable due to the strong rotational force of the motor.

Therefore, the unstable opening and closing operation of the opening and closing door is not only undesired operation of the new body, but also the noise generated, such as a large number of parts, the assembly process is complicated, the manufacturing cost and defect rate was increased.

The present invention is to solve the above-mentioned drawbacks, the forward and backward support plate of the new body according to the forward and reverse rotation of the motor is configured to operate more flexibly than the conventional so that the stable operation of the new body without noise At the same time to reduce the number of parts, to simplify the structure to facilitate the cooking process, it will be described in detail by the accompanying drawings as follows.

In the new actuating mechanism (5) provided with a weft worm (2) affixed to the motor shaft of the ordinary motor (1) and the operating means of the electromagnet (3) and the permanent magnet (4), the new actuating mechanism (5) Support shaft (9) in which the shaft rod (7) is fixed to one side of the bottom plate (6) to form a), and the driven spur gear (8) integrally formed at the bottom of the biaxial support rod (7) Injecting, but the inside of the support cylinder (9) which is integrally formed with the driven spur gear (8) through the spring (10) was inserted into the circulating spur gear side (11) interlocking with the weft (2), the shaft Inserting the insertion slot 12 in the upper portion of the rod (7) so that the prime spur gear (11) is placed, and then screw the adjustment screw 13 at the distal end of the shaft rod (7) while weaving (2) The rotational force of the driven spur gear 8 integrated with the support cylinder 9 is flexibly reduced by the elastic force of the spring 10 that is pressed by the spherical spur gear 11 that is engaged with and rotated. In addition, the rack 16 is formed on one side of the forward and backward support plate 15 in which the new body 14 is placed on the upper surface, and interlocks with the driven spur gear 8 to drive the driven spur gear 8. In accordance with the forward and reverse rotation of the new body 14 is to be combined so as to move forward and backward.

In the drawings, reference numeral 17 is an opening and closing door, 18 is a power lead wire, 19 is a connecting rod installed on the front and rear support plate 15 and the opening and closing door 17 having the new body 14 at the upper surface, 20 is the first jaw, 21 is the second lower jaw, 22 is the operation period, 23 is the annular hole, 24 is the speaker, 25 is the indentation guide, and 26 is the stone mark.

Referring to the operation and effects of the present invention by such a configuration as follows.

First, the watch body (not shown) is a circuit board mounted inside the watch body in order for the bird body 14 to open and close the door 17 to utter a bird sound corresponding to each hour. (Not shown) DC power is applied to the motor 1 and the electromagnet 3 through the lead wire 18, and the motor 1 is condensed on the motor shaft as the motor 1 rotates forward and backward for a few seconds. The prime spur gear 11 meshed with the worm 2 is also rotated forward and reverse.

In order to start the opening / closing operation of the opening / closing door 17, the driving spur gear 11 rotates by the strong forward rotation of the motor 1.

The driven spur gear 8 also rotates together by frictional action of the spring 10 interposed between the prime spur gear 11 and the driven spur gear 8.

At this time, the holding force of the spring 10 is to depressurize or pressurize the insertion tool 12 which is reciprocating the motive spur gear 11 according to the loosening and tightening of the adjusting screw 13, and at the same time, the pressure of the spur spur gear 11 is pressed. The strength of the friction action due to the spring force of the spring is determined accordingly.

If the driven spur gear 8 continues to rotate, the driven spur gear 8 meshes with the rack 16 formed on one side surface of the front and rear support plates 15 of the new body 14, and thus the driven spur gear The front and rear support plate 15 is moved forward by the rotation of (8), and the opening and closing door 17 is opened smoothly without noise while the connecting rods 19, which are installed on both sides of the back and rear support plate 15, move forward. New body 14 is protruded to the outside.

At this time, the forward spur gears are rotated by the rotation of the spur gear 11 at the moment when it stops by being stopped by the first stopper 20 by completely advancing to the front end of the rack 16 formed on one side of the back and forth support plate 15. 11) The grip force of the spring 10 interposed between the driven spur gear 8 exceeds the limit of the frictional force, so the driven spur gear 8 is not transmitted with the rotational force of the prime spur gear 11 and is slid between them. Since the driven spur gear 8 stops while being worn, and only the spur spur gear 11 rotates independently for several seconds, the powerful rotational force of the motor 1 is alleviated for several seconds so that the new body 14 opens and closes the door 17. Open and come out), it is flexible and stable operation without noise.

At the same time as the above, it is energized from the circuit board to the electromagnet 3, and the bird tail is formed in the annular hole 23 formed at one end of the up and down operation 22 by the repulsive force between the electromagnet 3 and the permanent magnet 4 described above. 14a is swept, so that the bird body 14 is uttered through the speaker 24, and the bird body 14 swept on the back and forth support plate 15 is also moved.

In addition, when the vocalization of birds sounds is completed, the motor 1 is energized again and reversely rotated, so that the worm spurs 2 of the motors engaged with each other as described above rotate together.

As the driven spur gear 8 rotates as the frictional action of the spring 10 interposed between the prime spur gear 11 and the driven spur gear 8 is released, the back and forth support plate 15 moves inward. At the same time as the original return, the opening and closing door 17 is completely closed by the backward of the connecting rod 19 remaining on the lower surface of the back and forth support plate 15.

At this time, as described above, the moment the rear end of the rack 16 formed by the forward and backward support plate 15 is completely retracted and stopped by the second stopper 21, the motive gear 11 is stopped for several seconds. Although the rotation continues, the elastic force of the spring 10 held between the primary spur gear 11 and the driven spur gear 8 exceeds the frictional force limit, and the driven spur gear 8 rotates due to the sliding action between the two. This stops and only the driving spur gear 11 independently idles for a few seconds, thereby relieving the powerful rotational force of the motor 1 to close the opening and closing door smoothly without noise.

That is, the operation of the new body 14 and the opening / closing door 17 may be made flexible by frictional action of the spring 10 interposed between the prime spur gear 11 and the driven spur gear 8. As such, the friction force between the spring 10 can be adjusted according to the elastic modulus of the spring 10.

The present invention as described above has a frictional force by the spring force of the spring in accordance with the forward and reverse rotation of the motor through the spring between the prime spur gear and the driven spur gear and the driven spur gear that meshes with the weft of the motor The driven spur gear rotates, and the driven spur gear and the rack part of the support body for the forward and backward movement of the new body are engaged with each other so that the forward and backward movement of the support plate for the forward and backward motion is achieved. Since the assembly process is easy to be reduced and reduced, there is an economical and practical advantage.
