Abstract
The utility model relates to a spring shell of a serinette, which comprises a shell body and a speed regulator bracket connected integrally with the shell body. A pile hole is arranged on the shell body, the lower part of the speed regulator bracket is provided with a circular concave disk, a circular arc slot hole is arranged on a top plate of the speed regulator bracket, and one circular arc top plate connected with the shell body is formed on the center of the top plate of the speed regulator bracket. The top surface of the shell body is additionally provided with a reinforcing rib. The utility model increases the elasticity of the top part of the speed regulator bracket, in the assembly process of the serinette, a worm of a speed regulator is not easily damaged, and simultaneously, the compression and collision resisting capabilities of the spring shell are enhanced.
Description
The utility model relates to a kind of Shell of spiral power spring for musical instrument, is the improvement to the musical box part.
Existing Shell of spiral power spring for musical instrument, its housing all fuses with the speed regulator support, and is to form with the plastics single injection-molded.The rigidity of this clockwork spring shell is relatively poor, easily chipping when pressurized or bump, in addition then, the supported underneath of speed regulator support the speed governing worm screw, after workman's assembling, find worm screw flexural deformation, or too carefully, too thick or the like quality problems, when needing transposing, the bigger strength of necessaryization is speed regulator support jack-up, could release worm screw, usually make the clockwork spring shell cracked sometimes because of overexerting.The patent No. is that defective at above-mentioned prior art designs for " 97102394.8 ", " speed regulating stand of eight-categorie musical instrument ".It adopts the top open-work of speed regulator support, loads onto a removable lining at any time bearing trap, though needn't change the big strength of expense, the running program of shirking, loading onto is cumbersome after all, and needsization are time-consuming, influences the assembling speed of complete machine.
The purpose of this utility model is the defective at prior art, for musical box manufacturer provides a kind of new parts kind.
Task of the present utility model is achieved in that this Shell of spiral power spring for musical instrument includes housing, and the speed regulator support that fuses with housing, have a hole on the housing, there is a circular recessed dish top board below of speed regulator support, on its top board, have arc-shaped slot, make in the top board of speed regulator support and be formed centrally a circular arc top board that links to each other with housing; End face at housing is set up reinforcement, to increase housing compressive strength; The tapered body of the inner peripheral surface of the recessed dish of square circular under the top board of speed regulator support.
Speed regulator support top drilling of the present utility model forms the circular arc top board, increased elasticity, it is very easy and convenient to change the speed governing worm screw, housing is set up reinforcement simultaneously, improved clockwork spring shell intensity, moreover the circular recessed dish inner peripheral surface of speed regulator support below is processed into cone-shaped body, can increase the sensitivity of speed governing.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model A-A cut-open view.
Accompanying drawing is a kind of embodiment of the present utility model.Shown in the figure, this musical box is decided the bar shell and is comprised housing 1, the speed regulator support 2 that fuses with housing 1, have three stake holes 3 on the housing 1, its end face has additional reinforcement 7, a recessed dish 4 of circle is arranged below speed regulator support 2, the tapered body of the inner peripheral surface of this recessed dish 4, the top board of speed regulator support 2 has arc-shaped slot 5, make in the top board of speed regulator support 2 and be formed centrally a circular arc top board 6 that is connected with housing 1, during use, speed regulator support 2 from top to bottom damper is housed, fan blade, worm screw covers, and the clockwork spring shell is fixedly connected by stake hole 3 and musical movements baseboard.
