Abstract

A binding needle made of metal and plastic relates to a binding needle, and adopts the structure that a pointed needle head (1) is arranged at the upper part of a needle rod (2); a thread passage (3) is arranged from needle head (1) at the upper part to the lower end of the needle rod (2); the needle rod (2) adopts a C-shaped structure; the outer edge at the part between the upper part and the lower end (9) of the needle rod (2) is coated in a needle bed (5), and the needle bed (5) adopts a C-shaped structure; the part between the upper part and the lower end (9) of the needle rod (2) is jointed with the inner wall of the needle bed (5); the opening of the C-shaped needle rod (2) is opposite to the C-shaped needle rod (7) of the C-shaped needle bed (5); and an arc-shaped bayonet (6) is arranged on one side of the needle bed (5). As the metal needle rod is coated in the needle bed, the needle bed performs a flexible protection function for the needle rod to ensure that the needle rod cannot bend.

Description

A kind of metallo-plastic binding needle

[technical field]

The utility model relates to a kind of binding needle, especially relates to a kind of drop or lap seam that is used to bind clothes, article and denim article and uses the metallo-plastic binding needle.

[background technology]

Commercially available rifle pin needle body comprises needle stand, shank, needle point and drawing lines at present; Be metal construction mostly, wherein the drawing lines on the shank is formed by the shank bending, and is unreasonable owing to designing in actual the use; Occur penetrating in the process front portion of needle point easily and hold folding, cause penetrating of needle body not smooth; The drop hardness of known denim or dress papery or plastic material is higher, and needle point must have comparatively hard structure and the least possible resistance, so that penetrate the higher material of hardness such as denim smoothly.

[summary of the invention]

In order to overcome the deficiency in the background technology, the utility model discloses a kind of metallo-plastic binding needle, said metallo-plastic binding needle is formed the shank flexible protective by needle stand through the metal shank is wrapped in the needle stand, guarantees that shank bending can not occur.

In order to realize said goal of the invention, the utility model adopts following technical scheme:

A kind of metallo-plastic binding needle comprises shank and needle stand, and the top of shank is provided with pointed syringe needle; Top syringe needle to lower end by said shank is provided with drawing lines; Make said shank form " C " shape structure, outer rim is enclosed with needle stand in top to the shank lower end of shank, and said needle stand is " C " shape structure; The said needle stand inwall of the top of shank to shank lower end and " C " shape structure is fitted and " C " shape opening of the corresponding needle stand of " C " shape mouth of shank, is provided with the arc bayonet socket in a side of needle stand.

Described metallo-plastic binding needle, said shank and needle stand are set to one.

Described metallo-plastic binding needle, opening one side on needle stand top is provided with tangent plane.

Described metallo-plastic binding needle, said tangent plane are " L " shape.

Described metallo-plastic binding needle, the opening part both sides of needle stand are arc surface.

Owing to adopted technique scheme, the utlity model has following beneficial effect:

The said metallo-plastic binding needle of the utility model is through being wrapped in the metal shank in the needle stand; Be connected with the rifle pin by said needle stand; Pin the arc bayonet socket of needle stand by the catch gear of rifle pin; The thimble of rifle pin just can be sent into " worker " font binding line in the bookbinding object through drawing lines comparatively like a cork, has guaranteed accurately putting in place and the binding rate of binding line.

Fig. 1 is the perspective view of the utility model;

Fig. 2 is the rear portion perspective view of the utility model;

Among the figure: 1, syringe needle; 2, shank; 3, drawing lines; 4, tangent plane; 5, needle stand; 6, arc bayonet socket; 7, opening; 8, arc surface; 9, shank rear end.

[specific embodiment]

Can explain in more detail that through following embodiment the utility model, the utility model are not limited to following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope;

In conjunction with accompanying drawing 1 or 2 described a kind of metallo-plastic binding needles; Comprise shank 2 and needle stand 5, the top of shank 2 is provided with pointed syringe needle 1, is provided with drawing lines 3 by top syringe needle 1 to the lower end of said shank 2; Make said shank 2 form " C " shape structure; 9 outer rims are enclosed with needle stand 5 in top to the shank lower end of shank 2, and said needle stand 5 is " C " shape structure, and said needle stand 5 inwalls of the top of shank 2 to shank lower end 9 and " C " shape structure are fitted and " C " shape opening 7 of the corresponding needle stand 5 of " C " shape mouth of shank 2; The both sides, opening 7 place of needle stand 5 are arc surface 8; Opening 7 one sides on needle stand 5 tops are provided with tangent plane 4, and said tangent plane 4 is " L " shape, are provided with arc bayonet socket 6 in a side of needle stand 5.

Implement the said metallo-plastic binding needle of the utility model; With metal shank 2 independent making; And leave drawing lines 3 in said shank 2 one sides, produce the structure of shank 2, needle stand 5 one then through injection-moulding device, be connected with the rifle pin by the arc bayonet socket 6 on the needle stand 5; Pin the arc bayonet socket 6 of needle stand by the catch gear of rifle pin; The thimble of rifle pin just can be sent into " worker " font binding line in the bookbinding object through the drawing lines on the shank 23 comparatively like a cork, and wherein the utility model has adopted the organic assembling of metal and two kinds of materials of plastics, has overcome the easy bending phenomenon of shank 2, needle stand 5 simple metal in the prior art.

The utility model does not detail part and is prior art.
