Detailed Description

The invention will be further elucidated and described with reference to the embodiments and drawings of the specification:

referring to fig. 3 and 4, the thread take-off structure for a radial shuttle includes a shuttle main frame 10 and a flag pole 20. The main shuttle flying frame 10 comprises a left shuttle column 11, the left shuttle column 11 is provided with an accommodating hole 12, and a telescopic assembly 30 is arranged in the accommodating hole 12. The flag pole 20 is inserted into the receiving hole 12 and connected to the telescopic assembly 30. The retractable element 30 can move or rotate in the receiving hole 12, so that the flag pole 20 changes the length or the angle exposed from the receiving hole 12.

After the left shuttle post 11 is opened with the receiving hole 12, the flag pole 20 is inserted into the receiving hole 12 and connected to the telescopic assembly 30 in the receiving hole 12. The retractable element 30 can move or rotate in the receiving hole 12, so that the flag pole 20 changes the length or the angle exposed from the receiving hole 12. The flag pole 20 is placed in the receiving hole 12 of the left shuttle post 11, and then the outgoing line of the radial shuttle is realized through the part exposed out of the receiving hole 12, the flag pole 20 is integrally designed with the left shuttle post 11, and the telescopic and rotary motion of the flag pole 20 is realized through the movement and rotation of the telescopic assembly 30 in the receiving hole 12 of the left shuttle post 11. Thus, the installation of the flag pole 20 to the left shuttle post 11 does not reduce the distance between it and the size ring 50, and then the telescoping and rotation of the flag pole 20 enables the radial shuttle to be adapted to weave a wide range of sizes of products. And the flagpole 20 and the left shuttle-pillar 11 are designed integrally, the flagpole 20 can not change the angle because of the pulling of the braided wire, the structure is simple and stable, the adjustment is convenient, and the cost is low.

Referring to fig. 4, 5 and 6, the telescoping assembly 30 includes an outer cone 32 and a tightening assembly 34. The outer taper sleeve 32 is provided with a through hole 322, and the flag pole 20 is inserted into the through hole 322 from the top of the outer taper sleeve 32 and then is abutted against the top of the outer taper sleeve 32. The outer diameter of the tightening assembly 34 is larger than the inner diameter of the through hole 322. The tightening assembly 34 is fixed to the flag pole 20 and inserted into the through hole 322 from the bottom of the outer taper sleeve 32, so that the side of the through hole 322 is deformed outward and abuts against the inner wall of the receiving hole 12. In this embodiment, the outer diameter of the outer taper sleeve 32 is smaller than the inner diameter of the receiving hole 12, so that the outer taper sleeve 32 can move up and down and rotate in the receiving hole 12 without being stressed. After the tightening member 34 is inserted into the through hole 322 of the outer cone 32, the flag pole 20 abuts against the top of the outer cone 32, so that the side of the through hole 322 is forced to deform outwardly and abut against the inner wall of the receiving hole 12. After the side edge of the through hole 322 abuts against the inner wall of the receiving hole 12, the outer taper sleeve 32 is fixed in the through hole 322 of the left shuttle post 11, and at this time, the outer taper sleeve 32 cannot move or rotate any more. And the flag pole 20 is fixed on the telescopic assembly 30 due to the abutment of the flag pole 20 and the top of the outer taper sleeve 32 and the pressure of the tightening assembly 34. When the length or the angle of the flag pole 20 exposed out of the receiving hole 12 needs to be adjusted, the fastening component 34 is taken out from the through hole 322 of the outer taper sleeve 32, then the outer taper sleeve 32 is moved or rotated, the flag pole 20 is adjusted to a preset position, and finally the fastening component 34 is inserted into the through hole 322 of the outer taper sleeve 32, so that the fixing of the flag pole 20 and the outer taper sleeve 32 is completed.

Referring to fig. 5 and 7, the tightening assembly includes an inner collar 342 and a tightening member 344 for forcing the inner collar 342 into the through hole 322. The flag pole 20 is threaded and the tightening member 344 may be a nut. The inner taper sleeve 342 has an outer diameter greater than the inner diameter of the through hole 322. The inner collar 342 is disposed on the flag pole 20, and the tightening member 344 is threaded on the flag pole 20 to force the inner collar 342 into the through hole 322. The portion of the flag pole 20 inserted into the external taper sleeve 32 is threaded such that the internal taper sleeve 342 is inserted into the through hole 322 by tightening the tightening member 344. Further, the outer diameter of the inner taper sleeve 342 increases from the top to the bottom of the inner taper sleeve 342, the outer diameter of the top of the inner taper sleeve 342 is smaller than the inner diameter of the through hole 322, and the outer diameter of the bottom of the inner taper sleeve 342 is larger than the inner diameter of the through hole 322. The top of the inner taper sleeve 342 is smaller than the through hole 322 of the outer taper sleeve 32, so that the inner taper sleeve 342 can play a role of guiding when inserted into the outer taper sleeve 32. Specifically, the inner taper sleeve 342 may have a trapezoidal cross section, and the cross section thereof gradually increases from top to bottom. The inner taper sleeve 342 may also be "T" shaped or triangular. In another embodiment, the tightening assembly 34 may also be an internally threaded inner collar 342. The inner collar 342 is directly threaded onto the threaded flag pole 20 and inserted into the through hole 322.

Further, referring again to FIGS. 5 and 6, the bore 322 includes a first section 323 and a second section 324 adjacent the inner collar 342. The first section 323 has an inner diameter greater than an outer diameter of the top portion of the inner collar 342 and the second section 324 has an inner diameter greater than the inner diameter of the first section 323 and less than an outer diameter of the bottom portion of the inner collar 342. As the outer diameter of the inner sleeve 342 increases from the top of the inner sleeve 342 to the bottom of the inner sleeve 342, the inner sleeve 342 presses against the intersection of the first section 323 and the second section 324 and the opening of the second section 324 simultaneously when the inner sleeve 342 is inserted into the outer sleeve 32. Causing the sides of the through-hole 322 to deform outwardly. At this time, the side edge of the through hole 322 has two stress parts with different heights, so that the outer taper sleeve 32 is not easy to damage when being extruded, and the outer taper sleeve 32 is easy to deform.

Further, an elastic member 36 is disposed between the outer cone 32 and the tightening assembly 34. To prevent locking between the outer cone 32 and the tightening assembly 34, a resilient member 36 may be provided between the outer cone 32 and the tightening assembly 34. In particular, the resilient member 36 may be a spring that is disposed between the outer taper sleeve 32 and the inner taper sleeve 342. When the tightening member 344 is tightened, the outer taper sleeve 32 and the inner taper sleeve 342 cannot be completely locked due to the force applied to the elastic member 36. When the fastener 344 is unscrewed, the inner taper sleeve 342 is ejected from the outer taper sleeve 32 due to the elastic force of the elastic member 36.

Further, the outer taper sleeve 32 is made of an elastic material. When the inner taper sleeve 342 extrudes the outer taper sleeve 32, the outer taper sleeve 32 made of elastic material can be deformed well and is not easy to damage. In particular, the outer cone 32 may be made of plastic. In another embodiment, in order to better deform the outer cone 32, the side of the outer cone 32 is provided with a plurality of deformation grooves 326 communicated with the through holes 322. After the outer taper sleeve 32 is provided with the deformation groove 326, the area of deformation needed to occur on the side edge of the outer taper sleeve 32 is reduced. In another embodiment, a plurality of deformation slots 326 communicated with the through holes 322 may be formed on the outer taper sleeve 32 made of the elastic material.

Referring again to fig. 7, the flag pole 20 includes an outlet portion 22 and a mounting portion 24. The outer diameter of the outlet portion 22 is larger than the inner diameter of the through hole 322. The outer diameter of the mounting portion 24 is smaller than the inner diameter of the through hole 322. The mounting part 24 is inserted into the through hole 322, and the outlet part 22 is abutted against the top of the outer taper sleeve 32. Further, a gasket 40 is arranged between the outgoing part 22 and the top of the outer taper sleeve 32. The gasket 40 can buffer the pressure of the outlet part 22 and the top of the outer taper sleeve 32, and reduce the damage of the outlet part 22 and the outer taper sleeve 32.

Referring to fig. 3 and 7 again, a first porcelain eye 14 is disposed on the left shuttle-post 11, and a second porcelain eye 26 is disposed on the flag pole 20. The second porcelain eye 26 is in a D shape, and the braided wire sequentially passes through the first porcelain eye 14 and the second porcelain eye 26. The second eyelet 26 cannot be placed too large because it is closer to the size ring 50 (the closer the braid is, the tighter the face). Second porcelain eye 26 is circular porcelain eye among the prior art, because the inner arc of circular porcelain eye is less, consequently when the pulling force when circular porcelain eye is qualified for the next round of competitions was too big, can lead to the braided wire to extrude to its centre to lead to the braided wire crease or fifty percent discount to appear, make the product yield reduce. In this embodiment, the second eyelet 26 is D-shaped, and the inner arc thereof is much larger than that of the circular eyelet under the condition of the same size as the circular eyelet, so that no matter how the tension of the braided wire changes, the braided wire is not creased or even folded.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
