Description

Music box ornament transmission mechanism

The utility model relates to the auxiliary equipment of music, and particularly a kind of music box ornament transmission mechanism, this transmission mechanism are to tighten clockwork spring by a handle that is installed on the winder, with the ornament rotation of drive installation on rotating disk.

The ornament that utilizes music box to make has been long-standing, and must the consumer like very much.This music box is to be power source with the spiral spring that is commonly called as, rotatablely move so as to output, this rotatablely moves by a transmission mechanism, make ornament produce the motion of expection, such as rotatablely move, rectilinear motion or oscillating motion etc., and also can be accompanied by musical sound at the volley, make the music box ornament have the enjoyment of the vision and the sense of hearing simultaneously.

Common a kind of typical music box ornament transmission mechanism in the daily life, as shown in Figure 1, 2, 3, the transmission mechanism of this typical music box ornament 10, comprise a hollow rotating disk 12, the upper surface that rotating disk 12 is installed in a base 13 rotates, and 24 of ornaments are to be fixed on the rotating disk 12, and the circumference of the centre bore 14 of rotating disk 12 is carved with the gear teeth 15, can with the upper surface that is installed in base 13, and three driven gears, 16 engagements of 120 ° of each intervals are rotated; This transmission mechanism 11 further includes a pedestal 17, pedestal 17 is fixed on the base by plural screw 18, be used for installing ornament 19 and music box 20, and music box 20 utilizes plural screw 25 to be fixed in the assembly room 26 of pedestal 17, and winder 21 extended downwards, so that a driving gear 22 to be installed, 16 of driving gear 22 and driven gears also are equipped with a sloth wheel gear, so as to changing direction of rotation.

When the user firmly rotates rotating disk 12, (seeing accompanying drawing 4), its force transmission makes it to rotatablely move for driven gear 16, thereby make sloth wheel gear 23 produce identical rotation, again by sloth wheel gear 23 to driving gear 22 transferring rotational motion, winder 21 is rotated, lay in elastic energy so as to tightening the clockwork spring (not shown); After clockwork spring tightens fully, when decontroling rotating disk 12, clockwork spring will discharge elastic energy lentamente, as power source winder 21 is rotated, this rotatablely moves and passes to rotating disk 12 by driving gear 22, sloth wheel gear 23 and driven gear 16, make the ornament 24 that is installed on the rotating disk 12 produce identical rotatablely moving, also can be accompanied by musical sound at the volley simultaneously, make music box ornament 10 have the enjoyment of the vision and the sense of hearing simultaneously.

Because common music box ornament 10 is to tighten clockwork spring with rotating rotating disk 12, and transmit motion by a series of gear 16,23,22 between rotating disk 12 and the winder 21, more so rub, energy loss is bigger, so it is harder to tighten clockwork spring with rotation rotating disk 12, thereby tighten the music box ornament 10 of clockwork spring with rotating disk 12, not only inconvenience but also require great effort in operation.

In addition, because of tighten the structure of clockwork spring with rotation rotating disk 12, get used to directly the terminal leader of installation of winder with common being seen other music box ornaments, the operator scheme that allows the user tighten clockwork spring is different fully, so that bought the sense that the consumer who tightens the music box ornament of clockwork spring by rotating disk often has the main threads of can not touch for the first time, pitch up manufacturer so do not know how to operate, increase the trouble of both parties on foot.

The purpose of this utility model be to provide a kind of not only intuitively but also leicht fallen D/A, the music box ornament transmission mechanism of being convenient to operate.

For achieving the above object, music box ornament transmission mechanism of the present utility model includes a base, a music box, a driving gear, a driven gear, a rotating disk, a hollow pressing plate, and music box is fixed on the base, its winder extends to the base below, and is bolted with the leader; One driving gear is directly tied the main shaft output at music box, rotates synchronously with main shaft; One driven gear is installed in base upper surface and rotates, and meshes with driving gear; One rotating disk is installed in base upper surface, its center hole circle Zhou Keyou gear teeth, and mesh with driven gear; One hollow pressing plate is fixed on the base, and there is the hole that is intended to avoid music box in its central authorities, and outer rim then is installed in disk upper surface.

Wherein, driving gear is a crown gear, and driven gear is a spur gear.

Wherein, driving gear is a helical gear, and this two helical gear of first spur gear that driven gear comprises a helical gear and is combined in this gear below is meshing with each other, first spur gear then with the gear teeth meshing of rotating disk.

Wherein, further comprise one second spur gear between the gear of first spur gear and rotating disk, this second spur gear is installed on the base upper surface axis of a cylinder and rotates, and respectively with the gears engaged of first spur gear and rotating disk.

The utility model is owing to adopt the leader that is spirally connected at the winder end to tighten clockwork spring, not only intuitively but also be convenient to operation, and avoided the not only power that existing music box ornament transmission mechanism need tighten that clockwork spring causes with rotating disk but also the defective of inconvenience.

Below in conjunction with drawings and Examples, technical characterictic of the present utility model is described further:
