The utility model content
The purpose of this utility model is to provide a kind of processing, a kind of split type stethoscope tin body that cost is low be convenient to.
Another purpose of this utility model is to provide a kind of cost low, the stethoscope tin assembly of being convenient to process.
One of goal of the invention of this utility model is achieved in that
A kind of split type stethoscope tin body includes the leading note passage on the can body, the leading note passage comprises sound collecting surface, voice guide hole and side voice guide hole; Wherein, the can body is made up of last can body and following can body two parts cooperation, and the said can body of part is provided with said sound collecting surface at least.Wherein go up the can body and cooperate with following can body two parts and be not limited to threaded engagement, interference fit also is clasped, spinner cooperation, interference fits or the like mode.
Further; Said sound collecting surface comprises sound collecting surface and following sound collecting surface; The said sound collecting surface of going up is positioned at said going up on the can body; Said down sound collecting surface is positioned on the said can body down, and the maximum gauge of said sound collecting surface down is less than the said maximum gauge of going up sound collecting surface, and said side voice guide hole is positioned at down on the can body.Perhaps said sound collecting surface is last sound collecting surface, and said last sound collecting surface is positioned at said going up on the can body, and said side voice guide hole is positioned on the following can body.
Further; Said voice guide hole comprises the last voice guide hole that is positioned at the can body and is positioned at the following voice guide hole of can body down; When the said can body and said down when the can body cooperates of going up, said voice guide hole and the said voice guide hole down gone up is communicated with and communicates with said side voice guide hole.
Further, said sound collecting surface is following sound collecting surface, and said sound collecting surface down is positioned on the said can body down, and said voice guide hole and side voice guide hole all are positioned at down on the can body, said under sound collecting surface through said voice guide hole and the conducting of said side voice guide hole.
Another goal of the invention of this utility model is achieved in that
A kind of stethoscope tin assembly comprises the can body, and be arranged in said can body on the leading note passage, said leading note passage comprises sound collecting surface, voice guide hole and side voice guide hole; Said can body is made up of last can body and following can body two parts cooperation; At least the said can body of part is provided with said sound collecting surface; At least part leading note passage is provided with the leading note layer; Said leading note layer comprises inside and outside, and the said outside of said leading note layer cooperates with said leading note passage, and the inside of said leading note layer communicates with said can body space in addition.
To this, said can body and leading note layer can adopt the unlike material preparation, but the material density of leading note layer should be greater than the material density of said can body.During because of the materials processing of high density material, relatively take cutter, and process time is also longer, the material cost of high density material is also than higher in addition.Thereby preparation can body adopts the relative leading note layer material of the density density of material low, effectively reduces the cost of can body on the one hand, in addition because the high material preparation of density that the leading note layer adopts has also effectively guaranteed hearing effect.
Can adopt rustless steel, steel, kirsite, copper, titanium alloy or the like preparation like the leading note layer material, and the can body can adopt engineering plastics, preparations such as engineering rubber, aluminium alloy.
