Abstract

The utility model discloses a latch needle, which comprises a needle handle, a needle hook and a needle latch. The needle hook is arranged at the top of one end of the needle handle, a needle latch gap is arranged at one end of the needle handle close to the needle hook, one end of the needle latch is rotatably installed in the needle latch gap, the other end of the needle latch extends out from the needle belly, the direction of the needle back is opposite to that of the needle belly, the length of the needle latch gap gradually decreases from the needle belly to the needle back, a groove is arranged on the needle back in the direction away from the needle hook and connected with the needle latch groove, 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 an unfixed end and overlapped on the end face of one end of the needle latch gap close to the needle hook. In the working process, the needle latch of the latch needle is reduced in sensitivity to errors, so that operation is reliable and service life is long.

Description

Latch needles

Technical field

The utility model relates to the flat machine technical field, particularly relates 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 utility model technical issues that need to address 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 utility model provides a kind of latch needles, comprises 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.The needle latch of the utility model 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 the further improvement of the utility model, 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.

The specific embodiment

As shown in the figure, the latch needles of the utility model 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.

Needle latch spring 6 usefulness Laser Welding are fixed in the groove 5.

The latch needles of the utility model 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 the needle latch of the utility model susceptibility to error in the process of work has reduced like this; 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.
