Abstract
The invention discloses a latch needle, which comprises a needle handle, a needle hook and a needle latch, wherein the needle hook is positioned on the top of one end of the needle handle; one end, close to the needle hook, of the needle handle is provided with a needle latch gap; one end of the needle latch is rotationally arranged in the needle latch gap, and the other end of the needle latch extends out of a needle belly; the needle back is opposite to the needle belly; the length of the needle latch gap is reduced from the needle belly to the needle back; a groove is formed in the direction of the needle back away from the needle hook and connected with the needle latch gap; and one end of a needle latch spring is a fixed end and fixed in the groove, and the other end of the needle latch spring is a movable end and lapped to the end face of the needle latch gap close to one end of the needle hook. The error sensitivity of the needle latch of the latch needle in the working process is reduced, so that the latch needle is reliable in operation and long in service life.
Description
Technical field
The present invention relates to the flat machine technical field, particularly relate to a kind of latch needles.
Background technology
Present latch needles is in the process of using, and needle latch can be swung on both sides, and an end swings to the closed position, and needle latch places on the pinhock, and an end swings to the position, back, and needle latch rests on the end face of needle latch seam away from pinhock one end.Needle latch susceptibility to error in the process of work is high like this, is unfavorable for operation, and service life is not long yet.
Summary of the invention
The technical issues that need to address of the present invention are that needle latch susceptibility to error in the process of work is high, are unfavorable for operation, and service life is not long yet.
For solving the problems of the technologies described above, the invention provides a kind of latch needles, comprise needle handle, pinhock and needle latch; Pinhock is positioned at the top of needle handle one end, and needle handle is provided with the needle latch seam at the end near pinhock, and needle latch one end is rotating to be installed in the needle latch seam; The other end stretches out from the pin tripe of needle handle, and position relative with the pin tripe on the needle handle is called needle back, and the direction away from pinhock on needle back has a groove; And link to each other with the needle latch seam, an end of needle latch spring is a stiff end, is fixed in the groove; The other end is stiff end not, rides on the end face of needle latch seam near pinhock one end.Needle latch of the present invention susceptibility to error in the process of work has reduced, and makes reliable, longer service life, and the product quality that processes is better.
As further improvement of the present invention, the needle latch spring is fixed in the said groove with Laser Welding.Laser Welding is not only easy to operate, also makes weld seam more solid attractive in appearance simultaneously.

Fig. 2 is a upward view of the present invention.
Wherein, 1-needle handle, 2-pinhock, 3-needle latch, 4-needle latch seam, 5-groove, 6-needle latch spring, 7-pin tripe, 8-needle back.
The specific embodiment
As shown in the figure, latch needles of the present invention comprises needle handle 1, pinhock 2 and needle latch 3; Pinhock 2 is positioned at the top of needle handle 1 one ends, and needle handle 1 is provided with needle latch seam 4 at the end near pinhock 2, and needle latch 3 one ends are rotating to be installed in the needle latch seam 4; The other end stretches out from the pin tripe 7 of needle handle 1, is called needle back 8 with pin tripe 7 relative positions on the needle handle 1, and the direction away from pinhock 2 on needle back 8 has a groove 5; And link to each other with needle latch seam 4, an end of needle latch spring 6 is a stiff end, is fixed in the groove 5; The other end is stiff end not, rides on needle latch seam 4 end face near pinhock 2 one ends.
Latch needles of the present invention is in the process of using, and needle latch can be swung on both sides, and an end swings to the closed position; Needle latch places on the pinhock, and the part that this moment, latch needles was positioned at needle latch seam can overwhelm on the needle latch spring, makes distortion of needle latch spring generation; The needle latch spring rides over the needle latch seam and leans on the end on the end face to move up along said end face, and needle latch is produced resiliency, and needle latch of the present invention like this susceptibility to error in the process of work has reduced; Make reliable, longer service life, and the product quality that processes is better; Laser Welding is not only easy to operate, also makes weld seam more solid attractive in appearance simultaneously.
