Abstract
The utility model discloses a take self-interacting transmission's music box, including box body and transmission, transmission includes clockwork spring, sound production steel sheet, cylinder, core pivot and driving plate, still includes an adjustment mechanism, adjustment mechanism is used for reducing the frictional force that produces between driving plate and the box body. The utility model discloses an adjustment mechanism both can promote the height of transmission in the box body, and the frictional force increase that produces between drive strap and the box body when the drive strap is toward eminence rotation can not appear again, causes the not enough problem of drive power.
Description
Technical Field
The utility model relates to an octave box technical field.
Background
Referring to the attached drawings 1 and 5 of the specification, a music box of a small vehicle model (such as a small train, a car and a small ship) with motion is commercially available, the music box comprises a box body 1 and a transmission device 2, the transmission device 2 comprises a spring 21, a sounding steel sheet 22, a roller 23, a machine core rotating shaft 24 and a transmission sheet 25, a track is arranged on the top surface of a combined body, and the small vehicle model can rotate along the track under the drive of the transmission sheet 25. However, the rotating shaft 24 of the inner movement of the music box cannot be absolutely perpendicular to the lower surface, so that the position of the transmission piece 25 is suddenly high and suddenly low in the rotating process of the transmission piece 25, and therefore, the induction part cannot always keep a certain distance from the upper surface, the induction magnetic force is unstable, and the small-sized vehicle model cannot be driven to rotate. If solve the unstable problem of response magnetic force through the height of adjusting transmission in the box body, the frictional force increase that produces between drive strap 25 and the box body when the drive strap 25 toward eminence rotation again appears, causes the not enough problem of driving force.
Disclosure of Invention
The utility model provides a take octave box from adjusting transmission, the purpose designs one kind and can be through reducing the frictional force that produces between drive plate and the box body, and then can adjust transmission highly solves because the change of drive plate 25 positions leads to the unstable and not enough problem of driving force of response magnetic force.
The utility model provides a take octave box from adjusting gear, includes box body and transmission, transmission includes clockwork spring, sound production steel sheet, cylinder, core pivot and driving plate, still includes an adjustment mechanism, adjustment mechanism is used for reducing the frictional force that produces between driving plate and the box body.
Furthermore, the adjusting mechanism is a spring plate, and the spring plate is arranged on the transmission piece.
Further, adjustment mechanism includes the installation piece, the installation piece is equipped with a mounting groove, the mounting groove is equipped with the spring pad, the mounting groove is located to the driving piece.
Furthermore, the adjusting mechanism comprises a connecting shaft, a groove is formed in the rotating shaft of the machine core, a spring is arranged in the groove, the connecting shaft is arranged in the groove, and the transmission piece is arranged on the connecting shaft.
From the above description of the present invention, compared with the prior art, the advantages of the present invention lie in:
the utility model discloses an adjustment mechanism both can promote the height of transmission in the box body, and the frictional force increase that produces between drive strap and the box body when the drive strap is toward eminence rotation can not appear again, causes the not enough problem of drive power.

Detailed Description
Example 1
Referring to fig. 1, 2 and 5, the music box with self-adjusting transmission comprises a box body 1 and a transmission device 2, wherein the transmission device 2 comprises a spring 21, a sound-producing steel sheet 22, a roller 23, a movement rotating shaft 24 and a transmission sheet 25. Different from the prior art, the music box of the technical scheme is also provided with an adjusting mechanism which is used for reducing the friction force generated between the transmission piece 25 and the bottom surface of the box body 2. The adjusting mechanism of the present embodiment is a spring plate 3, and the spring plate 3 is disposed on the transmission plate 25. Improve transmission 2's position or transmission piece 25 when rotating higher position, just can reduce the frictional force that produces between transmission piece 25 and the 2 bottom surfaces of box body by the setting of shell fragment 3, also can solve transmission piece 25 when rotating lower position, because of response magnetic force is not enough, can't drive small-size vehicle model pivoted problem.
Example 2
Referring to fig. 3, the adjusting mechanism includes a mounting plate 4, the mounting plate 4 is disposed on the rotation shaft of the movement, the mounting plate 4 is provided with a mounting groove 41, the mounting groove 41 is provided with a spring pad 42, and the driving plate 25 is disposed in the mounting groove 41. When the position of the driving unit is raised or the driving plate 25 is rotated to a higher position, the frictional force generated between the driving plate 25 and the bottom surface of the case 2 is also reduced by the spring pad 42.
Example 3
Referring to fig. 4, the adjusting mechanism includes a connecting shaft 5, a groove 6 is formed in the core rotating shaft 24, a spring 7 is arranged in the groove 6, the connecting shaft 5 is arranged in the groove 6, and the transmission piece is arranged on the connecting shaft 5. Through the arrangement of the spring 7, the position of the transmission device is improved or the friction force generated between the transmission piece and the bottom surface of the box body can be reduced when the transmission piece rotates to a higher position.
The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
