Abstract

The utility model discloses a butterfly triangle for a flat knitting machine. The butterfly triangle comprises a body, wherein the body is in central vertical line symmetry and is of a trapezoidal shape; a plane is formed on the lower edge of the trapezoid; two same M-shaped needle passing surfaces are connected onto the upper edge of the trapezoid; two symmetrical needle withdrawing surfaces are arranged on two sides of the body; acute angles are formed between the needle withdrawing surfaces and the lower edge of the body; the body surface comprises a U-shaped stepped surface, so that the widths of the M-shaped needle passing surfaces are smaller than the widths of the needle withdrawing surfaces; a triangular lug boss is arranged on the stepped surface; and the triangular lug boss is arranged with the central vertical line of the body as a symmetrical center and is integrally formed with the body. According to the butterfly triangle disclosed by the utility model, butts are convenient for needle receiving and are ease in trend; and the service life of the butts is prolonged.

Description

Straight-bar machines butterfly mountain

Technical field

The utility model belongs to the flat machine mechanical field, particularly straight-bar machines butterfly mountain.

Background technology

Computerized flat knitting machine more and more obtains more applications, and the cam system of Computerized flat knitting machine is installed in the head, along with the head side-to-side movement; Wherein the butterfly mountain is important function parts; It mainly is to play the position that stitch is pushed into braiding or tuck, perhaps when turning over pin, for connecing the pin stitch approach of taking the needle is provided; The stitch tracks that how to design the butterfly mountain is extremely important, and the dial shape of walking of triangle directly influences the service life that pin is called in person.

Summary of the invention

The purpose of the utility model provides a kind of straight-bar machines butterfly mountain, and it is rational in infrastructure, can guarantee effectively that knitting needle normally moves, and not fragile pin bell.

For this reason, the technical scheme that the utility model adopted is: straight-bar machines butterfly mountain comprises body; Body is central vertical straight line symmetry, and it is characterized in that: body is a trapezoidal shape, and trapezoidal lower edge is a plane; Trapezoidal upper limb is that 2 identical M shapes are walked the dial connection, and the body both sides comprise that 2 symmetries play dial, play dial and body lower edge and form acute angle; Body surface comprises a U-shaped step surface, makes M shape walk the width of the width of dial less than a dial; Said step surface is provided with a triangle boss, and said triangle boss is symmetrical set with the central vertical straight line of body, with the body global formation.

To further improvement of the utility model be: the drift angle of said triangle boss is 80 degree; Said dial becomes 52 degree angles with the body lower edge; It is 76 degree that said M shape is walked on the dial away from a protruding drift angle that plays dial.

To further improvement of the utility model be: the turning point on the body is arc transition and connects.

To further improvement of the utility model be: the surface of triangle boss and body surface are positioned on the same plane.

The body of the utility model is central vertical straight line symmetry, and body is near having some through holes near the lower edge, and screw passes through the through hole matching and fixing, and utilizes pin-and-hole to position simultaneously.When connecing pin; The pin bell is up to M shape along the triangle boss and walks dial; The drift angle angle design of triangle boss is that 80 degree and M shape walk on the dial away from a protruding drift angle that plays dial is the design of 76 degree, and the sharp corner arc transition connects, all can so that the pin bell to connect pin convenient; Tendency relaxes, and the life-span of protection pin bell.

Description of drawings

Explain further details below in conjunction with accompanying drawing and embodiment of the present invention.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is each face angle sketch map of the utility model.

The specific embodiment

Referring to accompanying drawing.This specific embodiment comprises that one is trapezoidal body, and the side of body both sides has been a dial 1, plays the angle that dial 1 and bottom margin form 52 degree; During tuck; The pin bell is up along playing dial 1, and the upper end 2 of playing dial 1 is the arcuation design, can not clash into the butterfly mountain when making the operation of pin bell.

Walking dial 31 and walking dial 41 of body upper limb forms 76 degree angles, and walking dial 32 also is to form 76 to spend angles with walking dial 42; Body surface is cut out a step surface 7 from upper limb to the bottom; Make the thickness of walking dial of body upper limb less than the thickness that plays dial 1,, have a triangle boss in the centre of step surface 7; The triangle boss comprises walking dial 8 and walks dial 9 that walking dial 8 is 80 degree with the angle of walking dial 9.When connecing pin, the pin bell is walked dial 32 along what walk that dial 8 is up to the body upper limb, walks out and connects the pin track along the dial 42 of walking of body upper limb subsequently, and vice versa.The surface of this specific embodiment intermediate cam boss and the surface of body are in one plane.

In this specific embodiment, screw 6 can and screw fit, can insert pin in the pin-and-hole 5 this specific embodiment is positioned.
