The knitting needle structure is matched with the needle plate. Generally, the knitting needle structure includes four needles with different functions, so it can be collectively called a set of four needles. The existing structure of the set of four needles is prone to phenomena such as needle dropping, reducing the knitting efficiency. In view of the above problems, the following proposes a solution. Content of the Utility Model

[0003] The purpose of the utility model is to provide a set of four needles for a full-functional flat knitting machine, which has the advantages of enhancing the connection reliability between the knitting needle and the long needle and reducing the probability of faults.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A set of four needles for a full-functional flat knitting machine includes a selecting needle, a spring needle, a long needle and a knitting needle. The selecting needle, the spring needle, the long needle and the knitting needle are all fixed in the needle slots of the external needle plate and are slidably connected with the needle slots. The long needle is provided with a needle head, the needle head is circular, the lower end of the knitting needle is provided with a blade slot, the blade slot is circular, the needle head is clamped into the blade slot, the knitting needle is further provided with a reinforcing rod, the top end of the reinforcing rod is located on one side of the blade slot, and the reinforcing rod is used to narrow the opening of the blade slot so that the needle head cannot move out of the blade slot from below.

[0006] Preferably, the lower end of the reinforcing rod is provided with a clamping portion, the top of the clamping portion is inclined to one side so that the clamping portion and the reinforcing rod are not in the same straight line position, the lower end of the clamping portion is horizontally bent towards the direction where the knitting needle is located so that a clamping groove is formed on one side of the clamping portion, one side of the long needle is provided with a long needle blade heel and a clamping block, the clamping block is located above the long needle blade heel, and the length of the clamping block is less than the length of the long needle blade heel. The clamping block is in clamping fit with the clamping groove, and the lower end of the clamping portion abuts against the upper end of the long needle blade heel.

[0007] Preferably, the selecting needle is provided with an upper front blade heel, a lower front blade heel, selecting teeth and a rear blade heel. The upper front blade heel, the lower front blade heel and the selecting teeth are all located on one side of the selecting needle, the rear blade heel is located on the other side of the selecting needle, the selecting teeth are located above the lower front blade heel, and the height of the selecting needle is 66 mm - 68 mm.

[0008] Preferably, the spring needle is provided with a spring blade heel and a spring foot. The spring foot is connected to the middle and lower position of the spring needle. The lowest position of the spring foot is lower than the lowest position of the spring needle. There is a gap between the spring foot and the spring needle. The lower end of the spring needle abuts against the rear heel of the needle selection. One side of the spring foot abuts against the inner side wall of the needle groove on the needle plate. The position of the spring blade heel is higher than the top of the needle selection. The rear side of the spring blade heel abuts against one side of the long needle.

Detailed Description of the Invention

[0017] The following is only the preferred embodiment of the present utility model, and the protection scope is not limited to this embodiment. Technical solutions within the concept of the present utility model shall fall within the protection scope of the present utility model. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom" and "top", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0018] As Figures 1 to 5 shown, a set of four needles for a full-functional flat knitting machine includes a selector needle 1, a spring needle 2, a long needle 3 and a knitting needle 4. The selector needle 1, the spring needle 2, the long needle 3 and the knitting needle 4 are all fixed in the needle slots of the external needle plate and are slidably connected to the needle slots.

[0019] The height of the selector needle 1 is 66 mm - 68 mm, and the height of the commonly used selector needle 1 in the prior art is 81 mm - 83 mm. The selector needle 1 used in this application is shorter, which can save costs and can achieve normal knitting in cooperation with the corresponding needle plate. The selector needle 1 is provided with an upper front heel 12, a lower front heel 13, a selector tooth 14 and a rear heel 15. The upper front heel 12, the lower front heel 13, the selector tooth 14 and the rear heel 15 are similar to the existing conventional designs. The upper front heel 12, the lower front heel 13 and the selector tooth 14 are all located on one side of the selector needle 1, and the rear heel 15 is located on the other side of the selector needle 1. The selector tooth 14 is located above the lower front heel 13 and is adjacent to the lower front heel 13.

[0020] The lower front heel 13 moves along the triangular track in the machine head, pushing the selector needle 1 to rise along the needle slot, so that the spring needle 2 is pushed to three different working positions by the rear heel 15, enabling the knitting needle 4 to meet different knitting requirements; the upper front heel 12 is used to press the raised selector needle 1 back to the starting position; the selector tooth 14 on the selector needle 1 is controlled by the selector swing piece of the selector on the external machine head.

[0021] The spring needle 2 is similar in structure to the existing spring needle 2. The spring needle 2 is provided with a spring heel 16 and a spring foot 17. The spring foot 17 is connected to the middle and lower position of the spring needle 2, and the lowermost position of the spring foot 17 is lower than the lowermost position of the spring needle 2. After being installed in the needle slot, the lower end of the spring needle 2 abuts against the rear heel 15 of the selector needle 1, one side of the spring foot 17 abuts against the inner side wall of the needle slot, the position of the spring heel 16 is higher than the top of the selector needle 1, and the rear side of the spring heel 16 abuts against one side of the long needle 3. There is a gap between the spring foot 17 and the spring needle 2. This design enables the spring foot 17 to generate an elastic force on the spring needle 2, enabling the spring needle 2 to work normally.

[0022] In this design, in order to match the specifications of the needle selection 1 and the needle plate, the height of the spring needle 2 is designed to be 60 mm - 62 mm, and the height from the top of the spring needle 2 to the lowermost end of the spring foot 17 is 69 mm - 71 mm. The height of the existing spring needle 2 is 68 mm - 70 mm, and the height from the top of the spring needle 2 to the lowermost end of the spring foot 17 is 86 mm - 88 mm.

[0023] A piece groove 6 is provided at the lower end of the knitting needle 4, and a reinforcing rod 7 is also provided on the knitting needle 4. The top end of the reinforcing rod 7 is located on one side of the piece groove 6. A side between the upper end of the reinforcing rod 7 and the knitting needle 4 together forms the piece groove 6. The piece groove 6 is an incomplete circle, and its integrity is greater than 75%. A piece head 5 is provided on the long needle 3. The piece head 5 is circular, and the diameter of the piece head 5 is slightly smaller than the diameter of the piece groove 6 but larger than the width of the opening of the piece groove 6. The width of the opening of the piece groove 6 is slightly larger than the width of the connection between the long needle 3 and the piece head 5. Before being installed into the needle groove, the piece head 5 of the long needle 3 can be inserted into the piece groove 6 from the side. When the long needle 3 and the knitting needle 4 are installed into the needle groove, since the width of the needle groove is similar to the widths of the long needle 3 and the knitting needle 4, the long needle 3 cannot move laterally. Also, since the piece head 5 cannot be removed from the opening of the piece groove 6, the long needle 3 and the knitting needle 4 cannot be separated, thus reducing the failure rate.

[0024] A clamping portion 8 is provided at the lower end of the reinforcing rod 7. The top of the clamping portion 8 inclines to one side, and the lower end of the clamping portion 8 bends horizontally towards the direction where the knitting needle 4 is located, so that a clamping groove 9 is formed on one side of the clamping portion 8. A long needle piece heel 10 and a clamping block 11 are provided on one side of the long needle 3. After the long needle 3 is installed on the knitting needle 4, the clamping groove 9 will be sleeved on the clamping block 11, and the lowermost end of the clamping portion 8 will abut against the upper end face of the long needle piece heel 10. The length of the clamping portion 8 is less than the length of the long needle piece heel 10, so it will not affect the normal operation of the long needle piece heel 10.

[0025] In the above - described specific embodiments, the technical problems solved, technical solutions, and beneficial effects of the present utility model have been further described in detail. It should be understood that the above - described are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
