Description of drawings
Figure of description is used to provide further understanding of the present invention, constitutes a part of the present invention, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not constitute improper restriction of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the pipe connecting structure that is used for the powder guide of prior art;
Fig. 2 is the structural representation according to the pipe connecting structure that is used for the powder guide of the embodiment of the invention.
Embodiment
Need to prove that under the situation that does not clearly limit or do not conflict, the feature among each embodiment of the present invention can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
In order to overcome in the prior art defective of the pipe connecting structure that is used for the powder guide, the invention provides the pipe connecting structure that is used for the powder guide after a kind of the improvement.
Fig. 2 is the structural representation according to the pipe connecting structure that is used for the powder guide of the embodiment of the invention.As shown in Figure 2, this pipe connecting structure comprises soft cloth pipe 10 and hard tube 30.The lower end of soft cloth pipe 10 is that first end is connected as first end with the upper end of hard tube 30.The upper end of soft cloth pipe 10 is the supplied materials end of powder, towards the falling direction of powder as second end.The lower end of hard tube 30 is connected to filler weigher 40 as second end.
The larynx hoop is also referred to as clip or Rubber tube clip, be to be applicable to fastening piece soft, the hard tube joint, being widely used in the conveyance conduit of various water, oil, vapour, dirt etc. in the fields such as automobile, tractor, fork truck, locomotive, boats and ships, mine, oil, chemical industry, pharmacy, agricultural, is a kind of desirable connection fastening piece.
That the larynx hoop mainly is divided into is English, American, three kinds of moral formulas, also has other derived products such as Europe superscript larynx hoop in addition.The material of English larynx hoop is iron, plating zinc on surface, and it is zinc-plated to be commonly called as iron, and torsion is moderate, low price, applied range.
The material of moral formula larynx hoop is iron, and plating zinc on surface, its button are apart from for impact briquetting, and torsion is big, moderate higher, be subjected to the production link cost high to restrict market share low.
American larynx hoop is divided into two kinds of the zinc-plated and stainless steels of iron, main specific for button apart from for punching shape (being the through hole button), based on stainless steel, be mainly used in high-end markets such as automobile fitting on the market, its price is higher than other two kinds.
Can actual demand among this embodiment, adopt in English larynx hoop, American larynx hoop and the moral formula larynx hoop any one, also can adopt the other forms of joint outer part except the larynx hoop.
With reference to Fig. 2, present embodiment is compared with prior art shown in Figure 1, and difference is, first end of soft cloth pipe 10 also is connected on the internal surface of first end of hard tube 30 by inside collar 50.Inside collar 50 is the interconnects that comprise piston ring.
First end of soft cloth pipe 10 comprises the second U-shaped bending section that the opening first U-shaped bending section that makes progress and the opening that is connected the outside of the first U-shaped bending section make progress, the first U-shaped bending section is positioned at the inboard of hard tube 30, and the second U-shaped bending section is set in first end of hard tube 30.The outside of the second U-shaped bending section is arranged with larynx hoop 20, and is connected the outer surface of hard tube 30 by this larynx hoop.Be provided with inside collar 50 in the opening of the first U-shaped bending section, and be connected by this inside collar on the inner surface of hard tube 30.
Thus, make joint at soft cloth pipe 10 and hard tube 30, the internal diameter of soft cloth pipe 10 is less than the internal diameter of hard tube 30, the upper end that has structurally guaranteed hard tube 30 can not form the buildup district, along the powder falling direction shown in the arrow B, powder all drops in the filler weigher 40 by hard tube 30 along soft cloth pipe 10.
Thereby by such structure, the guide process is smooth and easy, the working life that is conducive to improve the weighing precision of powder and prolongs the soft cloth pipe.
Certainly, except inside collar 50, can also adopt other interconnects with similar functions, as long as the part of soft cloth pipe 10 can be connected on the internal surface of hard tube 30, just can be so that the internal diameter of soft cloth pipe 10 less than the internal diameter of hard tube 30, can be realized the present invention's purpose.For example, can adopt a plurality of screws or rivet etc. as interconnect, also can adopt in the method for paste and connect.
And, be enough to guarantee at this interconnect also can only adopt this interconnect under the situation of join strength of joint, need not to adopt the joint outer part of larynx hoop and so on, thereby simplify the structure, provide cost savings.
The pipe connecting structure for the powder guide of the present invention has been described according to embodiment in the front, but the pipe connecting structure that should be used for the powder guide is not limited in the parts described in this embodiment and/or annexation, for example, except adopting inside collar, can also adopt other interconnect, as long as the part of soft cloth pipe can be connected the internal surface of hard tube; Outside larynx hoop not necessarily; Under the situation that adopts joint outer part, also can adopt other joint outer part except the larynx hoop.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
