Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
A music box transmission device with a movable decoration part is shown in figures 1-2 and comprises a clockwork spring 1, a sounding steel sheet 2, a roller 3, a machine core rotating shaft 4 and a transmission piece 5 which are arranged inside a box body, wherein the machine core rotating shaft 4 is coaxially provided with a mounting piece 41, one radial side of the mounting piece 41 is provided with a rotating mounting groove 411, one end of the transmission piece 5 is rotatably connected with the rotating mounting groove 411, the upper surface of the other end of the transmission piece 5 is fixedly bonded with a magnet 51,
in one embodiment, as shown in fig. 2, one end of the driving plate 5 connected to the rotation mounting groove 411 is bent upwards to form a limiting portion 52, an outer wall of the limiting portion 52 abuts against an upper edge of an opening of the rotation mounting groove 411, and the driving plate 5 can be in a horizontal state when not being induced by magnetic force through the limiting portion 52, that is, the maximum distance between the driving plate 5 and the bottom surface of the case is shortened, so that an effective magnetic induction distance is ensured between the magnet 51 on the driving plate 5 and the moving decoration.
In one embodiment, as shown in fig. 2, a limiting groove 521 is formed between the limiting portion 52 and the driving plate 5, a lower end of the limiting groove 521 is a major arc groove, the mounting plate 41 rotates in the major arc groove, and the major arc groove and the mounting plate 41 are in clearance fit.
Further, in this embodiment, the opening width of the upper end of the arc-shaped slot is larger than the thickness from the edge of the mounting piece 41 to the outer edge of the rotation mounting slot 411. Therefore, when the driving strap 5 needs to be replaced, the driving strap 5 can be detached from the rotation mounting groove 411 only by rotating the driving strap 5 to be perpendicular to the surface of the mounting strap 41.
It should be noted that the opening width of the upper end of the arc-shaped groove is smaller than the width from the outer edge of the rotation mounting groove 411 to the edge of the mounting plate 41, that is, the driving plate 5 can be prevented from being separated from the rotation mounting groove 411 during the process of the up-and-down swing of the driving plate 5.
In one embodiment, the two sides of the upper opening of the position-limiting groove 521 are rounded, i.e. the two sides of the upper opening of the position-limiting groove 521 are smooth, so as to avoid accidental scratching when the driving plate 5 is installed. In addition, the corner resistance of the upper end of the limiting groove 521 can be reduced, and the driving plate 5 is conveniently separated from the rotating installation groove 411.
In one embodiment, the cross section of the rotation mounting groove 411 is square, and the square rotation mounting groove 411 can reduce the resistance of the corner relative to the round rotation mounting groove 411, thereby facilitating the limiting part 52 to pass through the rotation mounting groove 411.
In one embodiment, as shown in fig. 2, a weight-reducing groove 53 is formed at one end of the driving strap 5 away from the rotation mounting groove 411 and below the magnet 51, and the weight of the whole driving strap 5 can be reduced through the weight-reducing groove 53, so that the up-and-down swing of the driving strap 5 is lighter and the cost can be saved.
The utility model discloses a working process and beneficial effect as follows: when the driving strap 5 rotates to a higher position, because the driving strap 5 is connected with the rotation mounting groove 411 in a rotating manner, one end of the driving strap 5 far away from the rotation mounting groove 411 has a downward force all the time under the action of gravity, so that the friction force generated between the driving strap 5 and the bottom surface of the box body can be reduced, and the movable decorating part can normally rotate.
The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
