Abstract

An improved rotating decorative device comprises: a fixed base, a rotating disk which is generally annular, a fixed plate, and a driving device. The driving shaft of the driving device comprises a square column section and a cylindrical section. A clutch disk is slidably sleeved on the square column section, and a clutch gear is pivotally mounted on the cylindrical section. A spring is arranged on the top surface of the clutch disk so that the clutch disk generates a force to fit the clutch gear. When the driving device drives the driving shaft, the clutch disk drives the rotating disk due to the elastic force of the spring, thereby achieving the effect of not generating reverse rotation when winding the spring and reducing the volume of the overall transmission part.

Description

Improved Rotary Decorator

The utility model relates to a musical toy, in particular to an improved rotary decoration device which has a clutch plate and a clutch gear, so that the clockwork does not reverse when it is wound up, and the volume of the overall transmission part can be reduced.

Existing rotary decoration device, as shown in Figure 4 and Figure 5, the main structure includes: a fixed chassis 91, a rotating disk 92, a tooth portion 921, a music recorder 93 with several predetermined bumps, a The music generator 94 of several monophonic metal shrapnels, a mainspring 95, a drive gear shaft 96, a drive gear 97 and an ornament 98 (such as a glass crystal ball, a marquee lampshade... etc.).

When the mainspring 95 is rotated to release energy, it will simultaneously drive the music recorder 93 and the coaxial drive gear shaft 96 to rotate. On the other hand, the drive gear shaft 96 drives the drive gear 97, and then the decoration 98 on the rotating disk 92 is rotated through the tooth part 921, thereby achieving simultaneous emission Music and the purpose of generating rotation.

Yet conventional device also has its shortcoming: the first, because whole transmission system does not have clutch device to exist, when winding up, can make this ornament 98 reverse. Second, because the drive gear shaft 96 extends outwards and drives a drive gear 97 that is not small in size, the overall width H becomes wider, so that the internal space at the bottom of the ornament can not be too small, and therefore, for the sake of Proportionality is not suitable for decorative objects 98 that are too small in size (especially spherical decorative objects, which will cause disproportionate troubles).

Therefore, the industry has been working hard to overcome the aforementioned shortcomings.

The main purpose of this utility model is to solve the above problems and provide a rotary decoration device with a clutch disc and a clutch gear, so that the decoration will not be reversed when the mainspring is wound.

The second object of the present utility model is to provide an improved rotary decoration device, so that the volume of the overall transmission part can be reduced.

Another object of the present invention is to provide an improved rotating decoration device, so that it has a more stable and smooth rotating motion.

In order to achieve the above object, the utility model takes the following technical solutions:

An improved rotary decoration device, which includes: a fixed base with several receiving parts; a generally annular rotating disk, which is slidably erected on the receiving part, and a decoration is arranged on the rotating disk; a fixed A plate, which is fixed above the fixed base, so that a predetermined space is formed therebetween; a drive device, which is located on the fixed plate, and a drive shaft extends downward from the drive device; the improvement is that the aforementioned drive shaft It has a square column section and a cylindrical section. The square column section is slidingly sleeved with a clutch disc. The bottom surface of the clutch disc is provided with several unidirectionally inclined ratchet parts. Each ratchet part has a vertical part and an inclined surface. The above-mentioned cylindrical section is pivotally equipped with a clutch gear, and the top surface of the clutch gear is provided with several mutually connected and unidirectionally inclined recesses corresponding to the corresponding ratchet parts. Each recess also has a vertical section and an inclined section. , the top surface of the clutch disc is provided with a spring, so that the clutch disc generates a force to fit the clutch gear, and the clutch gear is then meshed with a gear set, which is connected with the rotating disc to drive the rotating disc to rotate.

In this way, when the driving device drives the drive shaft, due to the elastic force of the spring, the vertical section of the clutch disc will finally touch the vertical section along the concave slope section of the clutch gear, and drive the clutch gear, gear set and rotation plate.

Hereby give a preferred embodiment and cooperate with accompanying drawing to describe in detail as follows:

Fig. 1 is a sectional view of the utility model.

Fig. 2 is a top view of the utility model.

Fig. 3 is a three-dimensional exploded schematic view of the internal structure of the utility model.

Figure 4 is a top view of a conventional device.

Fig. 5 is a front view of a conventional device.

Please refer to Fig. 1 to Fig. 3, the improved rotary decoration device of the utility model includes:

A fixed base 1 with several receiving parts 11;

A generally ring-shaped rotating disk 2, which is slidably erected on the receiving portion 11, and a decoration 21 is arranged on the rotating disk 2;

A fixed plate 3, which is fixed on the top of the fixed base 1, so that a predetermined space is formed therebetween;

A driving device 4 , the present embodiment adopts a hand forwarding bar, which is located on the fixing plate 3 , and a driving shaft 41 extends downwards from the driving device 4 .

Aforesaid driving shaft 41 has a side column section 411 and a column section 412, and this square column section 411 is to slide and cover a clutch disc 5, and the bottom surface of clutch disc 5 is provided with several ratchet parts 51 of about 30 degrees of unidirectional inclination, each A ratchet part 51 has a vertical part 511 and an inclined part 512; Each recess 61 is connected to each other and unidirectionally inclined, and each recess 61 also has a vertical section 611 and a slope section 612. The top surface of the clutch disc 5 is provided with a spring 7, so that the clutch disc 5 produces a fitting clutch gear 6 Power, the clutch gear 6 meshes with a gear set 8, and then can drive the rotating disk 2 to rotate.

In this way, when the driving device 4 drives the drive shaft 41, due to the elastic force of the spring 7, the vertical section 511 of the clutch disc 5 will finally abut against the vertical section 611 along the slope section 612 of the recess 61 of the clutch gear 6 , and drive the clutch gear 6, the gear set 8 and the rotating disc 2.

On the contrary, when winding (referring to the above-mentioned driving device 4), the phenomenon of reverse rotation of the clutch disc 5 is caused. paragraph 612).

In addition, since the total width H is greatly reduced, the volume of the entire transmission part is reduced, and the size of the decorative objects that can be matched in the overall shape design is more flexible, and the applicable range is wider.

Therefore, the purpose of not reversing when winding the mainspring and reducing the volume of the overall transmission part can be achieved.

In fact, each of the above-mentioned receiving parts 11 has a steel ball 111 and a recess 112 for slidingly accommodating the steel ball 111, and the bottom surface of the rotating disk 2 has an arc-shaped concave angle 22, which can fit closely with the steel balls 111. Contact, to achieve the purpose of more stable and smooth rotation movement.

Of course, there are still many examples of the present invention, between which only the details vary. For example, the aforementioned gear set 8 is omitted so that the clutch gear 6 directly drives the rotating disk, or the entire gear set 8 is replaced by one gear.

In addition, the decoration 21 that can be matched with the present invention can be a glass water polo 1, a marquee lampshade, or other forms, and is not strictly limited.
