Description

Hand musical box toy

The utility model relates to toy, is the combination of a kind of musical box and hand toys.

Be that clockwork spring drives as existing musical box toy is many, the spiral spring power of musical box is both as the power source of pronunciation, and being again provides power for the motion with the various annexes of musical box interlock.The motion performance of this annex (as the doll doll) is more dull, and after doing of short duration performance, that need continue to perform talks about to such an extent that reopen clockwork spring again and again, cumbersome.

The purpose of this utility model is to release a kind of musical box toy that relies on manually as power, and the performance that it provides has subtle sudden, and temperament and interest is lively.

Adopt such technical scheme according to above-mentioned purpose the utility model: this hand musical box toy includes base plate, sounding drum fixed thereon, stand upright on sound poking tooth and the soundboard that is fixed on the sounding board seat on the sounding drum external cylindrical surface, it is characterized in that described sounding drum outboard end has one to drive the hand worm-and-wheel gear that sounding drum rotates, at described sounding drum medial extremity the generating mechanism of a perform their routines is arranged, described musical box is played has the built-in spring-supported toy body that is subjected to.

Above-mentioned hand worm-and-wheel gear can be formed by being contained in sounding drum outboard end and the worm gear that cooperates with the sounding drum outer end cap, worm screw and worm screw handle, and described worm screw handle can pass through the worm screw elastic circlip, and the worm bearing lid is fixed on the worm shaft bolster column.

Above-mentioned sounding drum outer end cap and worm gear junction can be provided with an anti-reverse mechanism.

Above-mentioned worm screw elastic circlip and worm screw handle junction can be provided with an axial limiting mechanism.

Above-mentioned perform their routines generating mechanism can be by being contained on the sounding drum medial extremity and the cam and an end of double as sounding drum inner end cap are constituted by spring-supported lever, and described lever can be fixed on the lever shaft support by lever shaft and lever shaft jump ring.

Above-mentioned toy can be a box body that has gland (18), and described lever (7) one end boss and gland (18) edge are fastened, and makes the spring (20) of supporting toy body (19) in the box be in compressive state.

Above-mentioned anti-reverse mechanism can comprise the ratchet that matches with ratchet in the ratchet on the sounding drum outer end cap and the worm gear back side.

Above-mentioned position-limit mechanism can include the buckle and the annular groove that is opened on the described worm screw handle on the described elastic circlip.

Above-mentioned gland can be connected with hinge with box body.

Compared with prior art, the utlity model has novel structure, advantage such as strong simple to operate, interesting.

The utility model is described in further detail below in conjunction with accompanying drawing embodiment:

As shown in Figure 1 and Figure 2, musical box of the present utility model by base plate (1), sounding drum (2) fixed thereon, stand upright on the sound poking tooth (18) on sounding drum (2) external cylindrical surface and form by the soundboard (9) that soundboard fixed screw (10) is fixed on the sounding board seat.There is one to drive the hand worm-and-wheel gear that sounding drum (2) rotates at sounding drum (2) outboard end, this mechanism is by being contained in sounding drum (2) outboard end and the worm gear (16) that cooperates with sounding drum (2) outer end cap (17), worm screw (12) and worm screw handle (14) are formed, and worm screw (12) is fixed on the worm shaft bolster column (15) by worm screw elastic circlip (11) worm bearing lid (13).For preventing the fit counter-rotating of worm gear, establish an anti-reverse mechanism in described sounding drum (2) outer end cap (17) and worm gear (16) junction, this mechanism comprises the ratchet (21) that matches with ratchet (22) in the ratchet (22) on the sounding drum outer end cap (17) and worm gear (16) back side, as shown in Figure 3.In order to make worm screw handle (14) axial restraint, be provided with one in described worm screw elastic chuck (11) and worm screw handle (14) junction by the buckle (24) on the worm screw elastic chuck (11) be opened in the axial limiting mechanism that the annular groove (23) on the worm screw handle (14) is formed, as Fig. 4, shown in Figure 5.At sounding drum (2) medial extremity a perform their routines generating mechanism is arranged, this mechanism is made of the lever (7) that a cam (3) that is contained in sounding drum (2) medial extremity and double as sounding drum (2) inner end cap and an end are supported by spring (6), lever (7) is fixed on the lever shaft support (8) by lever shaft (4) and lever shaft jump ring (5), when cam (3) rotates, an end in contact of projection on the cam (3) and lever (7).As can be seen from Figure 6, this toy is one to have the box body of elasticity gland (26), and gland (26) can be connected with hinge (25) with box body.Keep the toy body (19) (as the doll doll) that supported by spring (20) in the box body, block gland (26) edge by lever (7) one end boss, make gland (26) closure, under the elastic force effect of spring (6), lever (7) one end boss keep the elasticity crimped status with described gland (26) all the time.The spring (20) of the interior supporting toy body (19) of box body this moment also is in compressive state all the time.When lever (7) flange broke away from gland (26), gland was opened suddenly under the elastic force effect of spring automatically, and toy body (19) is just jumped out gland (26) suddenly rapidly under the elastic force effect of spring (20), outwards show, makes the people pleasantly surprised, as shown in Figure 7.

During use, at first shake worm screw handle (14), drive sounding drum (2) and rotate by worm screw (12), worm gear (16), thereby the sound poking tooth (18) on sounding drum (2) external cylindrical surface is stirred soundboard (9), make soundboard (9) send the melodious music of height.Simultaneously, the inboard cam of sounding drum (2) (3) also rotates with sounding drum (2), projection on the cam (3) and lever (7) one end in contact and on lift, otherwise spring (6) compression, lever (7) other end presses down, and at this moment lever (7) one end boss break away from gland (26), and gland (26) is opened rapidly, toy body (19) in the box body is also jumped out rapidly thereupon, can give one of people unexpected pleasantly surprised.
