Abstract
Conveniently change musical box of attenuator, including spring drum, bottom plate, worm, attenuator, the spring drum includes that the box body reaches and the box body links nose as an organic whole, and nose sets up in the worm top, sets up the hole among the nose, fixes in the hole on the worm. The utility model has the advantages of: 1. During the musical box assembly, reduce the assembly process, improved production efficiency, reduced the production cost, reduced the noise that produces simultaneously in the assembly, improved the tone quality of musical box. When changing the damping part of musical box, only need mention spring drum nose, therefore damping part replacement is convenient, swift, has left out processes such as in the past dismantling the screw. Still owing to left out bridge splint and screw, manufacturing cost has been reduced.
Description
Technical field
The utility model relates to a kind of musical box, particularly a kind of musical box that can be convenient for changing damper.
Background technology
The existing musical box being convenient for changing damper as shown in Figure 1, Figure 2, shown in, it comprises going barrel 1, sound cylinder 2, supporting screw 3, tablet 4, tablet screw 5, base plate 6, great wheel 7, mill pinlon 8, crosses gear 9, worm gear 10, worm screw 11, damper 12, winder 13, clockwork spring 14.
Clockwork spring 14 is supported by winder 13 and puts into going barrel 1, and great wheel 7 is fixed on winder 13, and great wheel 7 engages with mill pinlon 8.
Mill pinlon 8 and sound cylinder 2 are fixed together, and sound cylinder 2 is supported by supporting screw 3.
Tablet 4 is fixed on the base plate 6 of sound cylinder 2 side by tablet screw 5, and stirs tablet 4 by sound cylinder 2.
Mill pinlon 8 also engages with mistake gear 9, crosses gear 9 and engages with worm gear 10.
Worm screw 11 lower end is fixed on base plate 6, and worm screw 11 upper end is fixed by bridge clamping plate 15, and bridge clamping plate 15 2 end is fixed on base plate 6 by screw 16.Damper 12 and worm screw 11 are press-fitted integral, damper 12 and the friction of base plate 6 phase, and therefore damper 12 can pass through worm screw 11, worm gear 10, cross the velocity of rotation that gear 9 hinders control mill pinlon 8.
When musical box is played, first by the winder 13 that turns clockwise, rotate clockwork spring 14, great wheel 7 is rotated, and is rotated by gear driven mill pinlon 8 by great wheel 7, and mill pinlon 8 rotates rear drive sound cylinder 2 and rotates, and tablet 4 stirred by sound cylinder 2, and musical box music plays ring.Mill pinlon 8 rotates and also drove gear 9 to rotate by gear drive simultaneously, cross gear 9 and pass through gear drive, worm gear 10 is rotated, worm gear 10 is by Worm Wheel System, and worm screw 11 is rotated, and damper 12 also rotates, damper 12 rotates afterwards and base plate 6 rubs, produce frictional resistance, make the velocity of rotation of sound cylinder 2 even, control the musical performance speed of musical box.
Because damper 12 is critical components that musical box controls music-tempo, different song needs corresponding different damped parts, in the production of musical box being convenient for changing damper, often need to change damper, therefore whether convenient direct efficiency and the cost affecting musical box production of the replacing of damper parts.
Summary of the invention
Technical problem to be solved in the utility model be overcome prior art above-mentioned defect and provide a kind of side to be convenient for changing the musical box of damper, musical box can conveniently be produced.
The utility model solves the problems of the technologies described above adopted technical scheme:
Be convenient for changing the musical box of damper, comprise going barrel, base plate, worm screw, damper, it is characterized in that: the extension that described going barrel comprises box body and is connected as a single entity with box body, extension is arranged on above worm screw, providing holes in extension, worm screw upper end is fixed in hole.
Above-mentioned extension is resilient material, so more easily mentions extension, changes damper more easily.
Compared with prior art, the utility model has the advantage of:
1., during musical box assembling, damped part can assemble together with winder, great wheel, excessively gear, worm gear, decreases assembly process, improve production efficiency, decrease production cost, decrease the noise produced in assembling simultaneously, improve the tonequality of musical box.
2. when changing the damped part of musical box, only need mention going barrel extension, therefore damped part is changed convenient, fast, eliminates the operation such as knockout screw in the past.
3., owing to eliminating bridge clamping plate and screw, decrease manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing musical box.
Fig. 2 is the structural representation after existing musical box removes lid.
Fig. 3 is the structural representation that the utility model embodiment is convenient for changing the musical box of damper.
Fig. 4 is the structural representation that the utility model embodiment is convenient for changing the musical box other direction of damper.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is further described.
As shown in Fig. 3, Fig. 4, Fig. 2, be convenient for changing the musical box of damper, comprise going barrel 1, sound cylinder 2, supporting screw 3, tablet 4, tablet screw 5, base plate 6, great wheel 7, mill pinlon 8, cross gear 9, worm gear 10, worm screw 11, damper 12, winder 13, clockwork spring 14.
Clockwork spring 14 is supported by winder 13 and puts into going barrel 1, and great wheel 7 is fixed on winder 13, and great wheel 7 engages with mill pinlon 8.Mill pinlon 8 and sound cylinder 2 are fixed together, and sound cylinder 2 is supported by supporting screw 3.Mill pinlon 8 also engages with mistake gear 9, crosses gear 9 and engages with worm gear 10, see Fig. 2.
Tablet 4 is fixed on the base plate 6 of sound cylinder 2 side by tablet screw 5, and stirs tablet 4 by sound cylinder 2.
Worm screw 11 and damper 12 are press-fitted integral, damper 12 is fixed on worm screw 11 bottom, worm screw 11 lower end is fixed on base plate 6, damper 12 and the friction of base plate 6 phase, and therefore damper 12 can hinder the rotation of mill pinlon 8 by worm screw 11, worm gear 10, excessively gear 9.
The upper cover extension 19 of going barrel 1 is above worm screw 11, and extension 19 is provided with the hole 20 holding worm screw 11 upper end, and worm screw 11 upper end is fixed by passing hole 20.
When musical box is played, turn clockwise winder 13, and after rotating clockwork spring 14, great wheel 7 is rotated and driven mill pinlon 8 to rotate, and mill pinlon 8 drives sound cylinder 2 to rotate again, and tablet 4 stirred by sound cylinder 2, and musical box music plays ring.Simultaneously, mill pinlon 8 drove gear 9 to rotate by gear drive, crossing gear 9 makes worm gear 10 rotate by gear drive, worm gear 10 makes worm screw 11 and damper 12 rotate, damper 12 rotates afterwards and base plate 6 rubs, produce frictional resistance, make the velocity of rotation of sound cylinder 2 even, thus control the performance speed of musical box.
When damper parts 12 need to change, left-handed thumb or other instruments have broken certain height in the extending area 19 of going barrel, take off damped part 12 that is replaceable.
Due to new going barrel 1 structure, great wheel 7, winder 13, excessively gear 9, worm gear 10, worm screw 11 can be fixed with single going barrel part simultaneously, complete the assembling of musical box train part.
