DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0046] Embodiment 1

[0047] As shown in the structure diagram of the tail of the needle body in Embodiment 1 of the present application, the B part of the tail of the needle body is not subjected to bending treatment. Figures 1-23 As shown in the structure diagram of the tail of the needle body in Embodiment 1 of the present application, the B part of the tail of the needle body is not subjected to bending treatment.

[0048] As shown in the structure diagram of the tail of the needle body in Embodiment 1 of the present application, the B part of the tail of the needle body is not subjected to bending treatment. Figure 4 , Figure 10 As shown in the structure diagram of the tail of the needle body in Embodiment 1 of the present application, the B part of the tail of the needle body is not subjected to bending treatment.

[0049] The present application is through the movable loop spring 9 which can be deformed with pressure, and the corresponding avoiding slot C is arranged on the needle slot wall of the needle slot; when the needle moves downward and enters the needle slot, under the pressure of the slot wall, the movable loop spring 9 can be completely or partially accommodated into the movable loop spring mounting slot 10 of the needle body 2, so that the requirement of the single needle for the horizontal space of the needle bed is reduced, and thinner needle type can be designed, which can be used for high-density needle type manufacturing; when the needle moves upward and the movable loop spring 9 leaves the needle slot, under the condition of losing the pressure of the needle slot, the movable loop spring 9 automatically restores and pops up under the elastic force of itself, and restores to the maximum thickness, so that the space between the movable loop spring 9 and the needle body 1 is increased, the space for the joining needle to enter the movable loop spring 9 is increased, and the stability of the movable loop can be greatly improved, which will be described in detail later.

[0050] As shown in Figure 11 , when the front and rear needles cooperate to perform the movable loop action, the turning needle is high, the movable loop spring 9 of the needle will move out of the needle slot, and under the elastic action, the movable loop spring 9 will restore to the free state, as shown in Figure 3 , the insertion space is greatly increased, the head of the joining needle can be more easily inserted into the insertion space of the turning needle, and the movable loop action is more stable.

[0051] Further, the movable loop spring 9 is composed of a fixed piece 901, a fulcrum 902, an elastic piece 903, a movable loop part 904, a pre-joining needle part 905 and a spring head 906 in sequence; the elastic piece 903 is higher than the fixed piece 901, and the movable loop part 904, the pre-joining needle part 905 and the spring head 906 form an arc structure.

[0052] Further, a groove 7 is arranged on the surface of the needle stem 3 at the rear side of the needle tongue 6, which is used for accommodating the spring head 906; a concave shape 8 is arranged at the connection between the needle body 2 and the needle stem 3, and the concave shape 8 and the movable loop spring 9 form the movable loop space 11 of the needle; the fixed piece 901 of the movable loop spring 9 is riveted in the spring mounting slot 10, an avoiding space 12 is arranged in the spring mounting slot 10, and the avoiding space 12 is below the connection between the elastic piece 903 and the movable loop part 904.

[0053] The elastic piece 903 of the movable loop spring 9 is an elastic structure, when the movable loop spring 9 is pressed as a whole, the elastic piece 903 will bend downward as the fulcrum 902 is supported, and due to the structural design of the avoiding space 12, the elastic piece 903 can be bent greatly, so that the accommodation capacity of the movable loop spring mounting slot 10 is greatly enhanced, the movable loop spring 9 can be completely or partially accommodated into the movable loop spring mounting slot 10 of the needle body, and at this time, the movable loop spring 9 is in close contact with the needle slot under the elastic action of the elastic piece 903, which can make the needle work more smoothly and the fabric surface more flat.

[0054] AsFigure 3 Further, the depth of the avoiding space 12 is h1, and h1 is in the range of 0≤h1≤the thickness of the transfer spring mounting groove 10.

[0055] As shown in the figure, Figure 6 Further, the height of the elastic piece 903 is h2, the maximum height of the transfer spring 9 is h3, and 0

[0056] As shown in the figure, Figures 6-7 The free opening thickness h3 and the accommodation thickness h5 of the transfer spring 9 can be designed according to different needle types to meet the knitting requirements in various situations.

[0057] When the loop slides to the transfer part 11 of the needle after the transfer spring 9 is freely opened, the loop will generate a certain pressure F1 on the transfer spring 9, as shown in the figure, Figure 9 Therefore, the transfer spring must have a certain anti-deformation ability.

[0058] After the transfer spring 9 enters the needle slot, it is deformed under the action of the pressure F2 of the needle slot wall and is fully or partially accommodated into the spring mounting groove 10, so the transfer spring 9 is required to have a certain deformation ability.

[0059] The anti-deformation force of the transfer spring 9 is F, and F1

[0060] As shown in the figure, Figure 3 Further, after the transfer spring 9 is installed, the height between the highest position B of the transfer spring 9 and the bottom of the needle body 1 is h4, and the thickness of the needle body 1 is h, and h

[0061] Further, the width of the D of the elastic piece 903 of the transfer spring 9 is d1, the width of the spring mounting groove 10 is d2, and 0.5*d2

[0062] As shown in the figure, Figures 18-19 Further, the avoiding space 12 is a through-hole structure. In the case of ensuring the strength of the needle body, the design of the through-hole can greatly improve the accommodation depth of the transfer spring 9. When the loop density is loose on the thick needle needle type, the total height of the transfer spring 9 can be increased to ensure the stability of the transfer.

[0063] As shown in the figure, Figure 20 Further, the needle body 1 side close to the transfer space 11 is provided with a concave groove 1101. The design is hollowed out. When the transfer loop slides from the needle hook 5 to the transfer part of the thick needle, the dense loop has a process of expanding and then relaxing, which has a certain auxiliary effect on the stability of the transfer.

[0064] As shown in the figure, Figure 21As shown, further, the needle tail 4 of the needle body 1 is linear.

[0065] The conventional knitting needle relies on the elasticity of the bent part of the needle tail to press the needle body against the needle groove wall to increase the stability of the needle, but at the same time, a certain gap is needed to be designed between the needle body and the needle groove, which is usually 0.06mm-0.10mm.

[0066] The present application can replace the pressing force generated by the bent structure of the tail of the conventional knitting needle due to the close pressing of the transfer spring 9 and the needle groove without the transfer motion, so that the needle tail 4 of the needle body 1 can be designed as a straight line, thereby further reducing the gap between the needle body 1 and the needle groove, which is beneficial to the manufacture of high-density needles. The gap between the needle body and the needle groove can be reduced to 0.02mm-0.04mm, and at the same time, the manufacturing process of the knitting needle is simplified, which can effectively reduce the manufacturing cost of the knitting needle.

[0067] Embodiment 2

[0068] In this embodiment, the structure of the needle body is basically unchanged, and the design of the transfer spring 9 is changed, as shown in Figure 12 , Figure 13 When the knitting needle moves into the needle groove, the transfer spring is stored, as shown in Figure 13 , and the transfer spring 9 is provided with an elastic deformation fulcrum 907.

[0069] When the transfer coil enters the knitting needle turning part, under the action of the fabric tension and the tension of the coil itself, the transfer spring of the knitting needle is subjected to a pressing force F, which will increase under the condition of tight coil density or large fabric tension, which will cause the insertion space to be pressed, and in this embodiment, the elastic deformation fulcrum 907 is supported by the point, and the overall deformation resistance of the transfer spring 9 is enhanced, so that when the transfer coil enters the turning part of the knitting needle, the insertion space is not easy to be compressed, which is beneficial to increase the stability of the tightness of the coil.

[0070] Embodiment 3

[0071] In this embodiment, the structure of the needle body is basically unchanged, and the design of the transfer spring 9 is changed based on the design of the embodiment 2, as shown in Figure 14 , Figure 15 The transfer spring 9 is provided with a bending point 908 on the side of the elastic deformation fulcrum 907, and the bending point 908 is close to the side of the needle tail 4, which can increase the stability of the elastic deformation fulcrum 907, prevent the elastic deformation fulcrum 907 of the transfer spring 9 from being separated from the needle body after long-time work, and increase the fatigue resistance of the knitting needle.

[0072] Embodiment 4

[0073] In this embodiment, the structure of the needle body is basically unchanged, and the design of the transfer spring piece 9 is increased in bending on the basis of embodiment 2, like Figure 16 、 Figure 17 A bending area 909 is arranged on the transfer spring piece 9 on the side of the elastic deformation fulcrum 907, and the bending area 909 is close to the needle tail 4 side, which can increase the stability of the elastic deformation fulcrum 907, prevent the elastic deformation fulcrum 907 of the transfer spring piece 9 from being separated from the needle body after long time work, and increase the fatigue resistance of the needle.

For ordinary skilled persons in the technical field to which the present application belongs, some simple deductions or replacements can be made without departing from the concept of the present application, and all of them should be considered as falling within the protection scope of the present application.

Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
