Enter into connecting bushing 132, spring leaf 133 is relied on when use and shrinks the radial force generated, connecting bushing 132 and shaft 131
Axle journal is fitted close, and is made after using for a period of time, although the axle journal and 132 inner wall of connecting bushing of shaft 131 are worn, but bullet
The elastic force of reed 133 is held essentially constant, and can continue to damping action, to substantially prolong the use of Damping rotation shaft 13
In the service life, structure is simple, easy to use.
For the ease of the assembly of needle latch 12 and Damping rotation shaft 13.Further, tongue apertures is offered on the end of needle latch 12
122, open up that there are two axis hole 141, one end of shaft 131 and an axis holes in the two side walls in the notch of glossal canal 14 respectively
141 are rotatably connected, and the other end of shaft 131 passes through tongue apertures 122 and is rotatably connected with connecting bushing 132, in shaft 131
Portion is fixed in tongue apertures 122, and one end of connecting bushing 132 has a thread head 136 for fixing, thread head 136 and another
Axis hole 141 is threadedly coupled.Tongue apertures 122 is assembled convenient for the positioning of needle latch 12 and Damping rotation shaft 13, and axis hole 141 is convenient for Damping rotation shaft 13
Positioning with glossal canal 14 is assembled, and by the above process, carries out assembly work convenient for needle latch 12 and Damping rotation shaft 13.
In order to allow needle latch 12 and pinhock 11 close with activation pin mouth, ensure the knitting cycle of latch needles be able to smoothly into
Row.Further, the front end of needle latch 12 has tongue spoon 121, and the front end of pinhock 11 has the bill 111 for being bent into arc-shaped, tongue
Spoon 121 can be closed with 111 phase of bill.It is swung when needle latch 12 towards the direction close to pinhock 11 and swings to tongue spoon 121 and bill
111 be in contact position when, anesthesia needle mouth, when needle latch 12 towards far from pinhock 11 direction swing when, activation pin mouth, by above-mentioned
Process, allow needle latch 12 and pinhock 11 close with activation pin mouth, ensure that the knitting cycle of latch needles is smooth.
In order to make glossal canal 14 convenient for cleaning-nursing.Further, the rear end of pinhock 11 has needle top surface 112 and needle back face
113, glossal canal 14 extends to the notch arrangement that needle back face 113 forms perforation from needle top surface 112.Notch arrangement is communicating structure, just
The dirts such as dust, fiber head, grease, wax inside notch are accumulated in cleaning, relative to the groove structure cleaning not penetrated through
Simpler convenience, cleaning effect is more preferable, to ensure the knitting quality of latch needles.
After making the triangle in head push stitch 3, latch needles be can move up and down.Further, stitch 3 is called in person including needle
31 and backshank 32, the front end of needle heel 31 and shank 2 are integrally formed, and the rear end of needle heel 31 and backshank 32 are integrally formed.Needle heel 31
For the bulge-structure of the height higher than backshank 32.Triangle in head pushes the needle heel 31 of protrusion, and then latch needles is driven to carry out
Lower movement, stitch 3 use the structure of elongated backshank 32, convex needle heel 31, and when work can simply and effectively position and be stablized
Reliably be held on latch needles bed, and do not need that special positioning wire is installed, make latch needles positioning is simple, hold stablize, at
Circle quality is improved.
In order to be adapted latch needles from different needle stands according to different knitting requirements.Further, according to difference
Knitting requirements, the shank 2 of latch needles can use straight rod structure or forge piece of step type structure, to make latch needles and different needle stand phases
Adaptation, to complete different knitting requirements, improves the versatility of latch needles.
The utility model is described with reference to the preferred embodiments, and those skilled in the art know, is not departing from this reality
In the case where with novel spirit and scope, various changes or equivalence replacement can be carried out to these features and embodiment.This reality
