Description

Technical Field

[0001] This utility model belongs to the technical field of sock machine equipment, and in particular relates to an adjustable hook for sock machines. Background Technology

[0002] The sock knitting machine was first invented by the Englishman John Lee in 1589. It uses crochet to knit shaped sock pieces and is used to produce socks. In 1849, due to the application of latch needles to small-diameter circular knitting machines, single-cylinder circular sock knitting machines appeared. Initially, they produced cut socks, but it was not until 1857 that they began to knit socks with pocket-shaped heels and toes.

[0003] During operation, sock knitting machines require hooks to hook onto raw materials such as needles and thread and move back and forth to facilitate subsequent knitting processes. However, the positions of existing sock knitting machine hooks are mostly fixed, making it difficult to adjust their positions according to actual needs during production. This affects subsequent production and results in poor overall practicality. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-6 As shown, this utility model is an adjustable hook for a sock knitting machine, including a retaining tube 1, and further including: a guide groove 2 formed on the side wall of the retaining tube 1, the guide groove 2 being symmetrically distributed along the vertical center line of the retaining tube 1; a positioning hole 3 formed on the front end surface of the retaining tube 1, the positioning holes 3 being equidistantly distributed on both ends surface of the retaining tube 1; a sliding groove 4 formed on the inner side wall of the retaining tube 1, the sliding groove 4 being symmetrically distributed on the inner side wall of the retaining tube 1; an adjusting seat 5 distributed in the inner cavity of the retaining tube 1, and a slider 6 fixedly provided on the side wall of the adjusting seat 5; and an extension rod fixedly provided at the bottom center of the adjusting seat 5. Rod 7 and extension rod 7 are slidably connected to clamping tube 1 via adjusting seat 5. A return spring 8 is fixedly connected to the inner cavity of adjusting seat 5, and a positioning rod 9 is fixedly connected to the other end of the return spring 8. The positioning rod 9 is slidably connected to adjusting seat 5 via return spring 8, and the outer diameter of positioning rod 9 is adapted to the inner diameter of positioning hole 3. The two ends of return spring 8 are fixedly connected to the inner side wall of positioning rod 9 and the inner side wall of adjusting seat 5, respectively. An auxiliary sliding plate 10 is sleeved on the outer side of one end of positioning rod 9, and a locking structure is provided at the bottom end of extension rod 7.

[0026] During operation, when the extension length of the extension rod 7 needs to be adjusted according to actual usage requirements to facilitate subsequent adjustment of the position of the hook body 18, firstly, the adjusting ring 15 is moved so that it slides along the guide groove 2 through the guide blocks 16 symmetrically arranged on its inner sidewall. When the adjusting ring 15 moves longitudinally, the position of the magnet 17 also moves accordingly. Then, the attractive force exerted by the magnet 17 on the positioning rod 9 disappears. At the same time, the reverse force generated by the deformation of the return spring 8 pulled by the lateral movement of the positioning rod 9 will pull the positioning rod 9 in the opposite direction, thereby causing the positioning rod 9 to retract to the inner side of the adjusting seat 5. Then, when both positioning rods 9 on both sides have disengaged from the inner side of the positioning hole 3 and retracted back to the inner side of the adjusting seat 5, the longitudinal pull... The extension rod 7 moves longitudinally, causing the adjusting seat 5 to slide along the inner wall of the clamping tube 1. The adjusting seat 5 then causes the slider 6 to slide along the slide groove 4, thereby improving the stability of the adjusting seat 5 during longitudinal movement. After the adjusting seat 5 moves to the appropriate position, the positioning rod 9 moves to one side of the other positioning hole 3. At this time, the adjusting ring 15 is turned again, causing the magnet 17 to move back to one side of the positioning rod 9. Then, under the action of the magnet 17, one end of the positioning rod 9 is re-entered into the inner side of the positioning hole 3, realizing the positioning of the adjusting seat 5. The auxiliary sliding plate 10 can improve the stability of the positioning rod 9 during movement, which is convenient and quick, and has higher overall practicality.

[0027] Furthermore, the engaging structure includes an adapter groove 11, a protrusion 12, a through hole 13, and a positioning bolt 14. The adapter groove 11 is opened at the bottom end of the extension rod 7, and the inner cavity of the adapter groove 11 is provided with protrusions 12. The size of the protrusions 12 is adapted to the size of the groove 20, and the protrusions 12 are hexagonal. A through hole 13 is opened on one side of the bottom of the extension rod 7, and a positioning bolt 14 passes through the inner side of the through hole 13. The through holes 13 are symmetrically distributed on both sides of the bottom of the extension rod 7, and the size of the through holes 13 is adapted to the size of the positioning bolt 14.

[0028] During operation, since the size of the adapter groove 11 at the bottom of the extension rod 7 matches the size of the adapter block 19, when the adapter block 19 is inserted into the inner side of the adapter groove 11, the initial engagement connection between the hook body 18 and the extension rod 7 can be achieved. At the same time, the protrusion 12 will be inserted into the inner side of the groove 20 to further improve the stability of the engagement between the hook body 18 and the extension rod 7. When the two are fully engaged, the positioning bolt 14 is passed through the inner side of the through hole 13 and one end of it extends into the inner side of the bolt hole 21 to achieve a stable connection between the hook body 18 and the extension rod 7.

[0029] Furthermore, an adjusting ring 15 is sleeved on the outer side of one end of the card tube 1, and a guide block 16 is fixed on the inner side wall of the adjusting ring 15. The outer diameter of the guide block 16 is adapted to the inner diameter of the guide groove 2, and the guide blocks 16 are symmetrically distributed along the vertical center line of the adjusting ring 15. A magnet 17 is fixed on the surface of one end of the adjusting ring 15, and the magnets 17 are symmetrically distributed at both ends of the adjusting ring 15.

[0030] During operation, since the guide blocks 16 are equidistantly distributed along the inner wall of the adjusting ring 15, and the outer diameter of the guide blocks 16 is compatible with the inner diameter of the guide groove 2, when the adjusting ring 15 moves longitudinally, it will drive the guide blocks 16 to slide longitudinally along the guide groove 2, which facilitates the subsequent adjustment of the position of the magnet 17. This makes it easier to use the magnet 17 to suck the positioning rod 9, which has been moved to different positions, into the inner side of the positioning hole 3, thereby achieving the positioning of the adjusting seat 5.

[0031] Furthermore, a hook body 18 is distributed below the extension rod 7, and an adapter block 19 is fixed at the top center of the hook body 18. The outer diameter of the adapter block 19 matches the inner diameter of the adapter groove 11. A groove 20 is formed on the upper surface of the adapter block 19. The inner diameter of the groove 20 matches the outer diameter of the protrusion 12. Bolt holes 21 are symmetrically distributed along the vertical center line of the adapter block 19. A bolt hole 21 is formed on one end surface of the adapter block 19.

[0032] During operation, when it is necessary to achieve the snap-fit ​​connection between the hook body 18 and the extension rod 7, the adapter block 19 fixed at the top center of the hook body 18 is inserted into the adapter groove 11 opened at the bottom of the extension rod 7. At this time, the protrusion 12 will be inserted into the inner side of the groove 20, which facilitates the initial connection between the hook body 18 and the extension rod 7. When one end of the positioning bolt 14 is inserted into the inner side of the bolt hole 21, it is convenient to achieve the stable connection between the hook body 18 and the extension rod 7.

[0033] Furthermore, the positioning holes 3 are equidistantly distributed along both ends of the clamping tube 1, and the positioning holes 3 and the clamping tube 1 form an integrated structure;

[0034] During operation, since the positioning holes 3 are equidistantly distributed along both ends of the clamping tube 1, and the inner diameter of the positioning holes 3 is compatible with the outer diameter of the positioning rod 9, it is convenient to perform subsequent positioning processing on the adjusting seat 5 when one end of the positioning rod 9 is inserted into the inner side of the positioning hole 3.

[0035] Furthermore, the positioning rod 9 is slidably connected to the adjusting seat 5 via the return spring 8, and the positioning rod 9 is symmetrically distributed along the vertical center line of the adjusting seat 5;

[0036] During operation, when the magnet 17 attracts the positioning rod 9 under the action of magnetic force, the positioning rod 9 moves accordingly and pulls the return spring 8, realizing the deformation of the return spring 8. At the same time, one end of the positioning rod 9 is fed into the inside of the positioning hole 3, which facilitates the subsequent positioning of the adjustment seat 5.

[0037] Working principle: First, the hook body 18 is engaged with the inner side of the adapter groove 11 via the adapter block 19. Then, the protrusion 12 engages with the groove 20. Next, the positioning bolt 14 is inserted into the inner side of the bolt hole 21 to connect the hook body 18 and the extension rod 7. When it is necessary to adjust the extension length of the extension rod 7 to facilitate subsequent adjustment of the position of the hook body 18, the adjusting ring 15 is moved so that it slides along the guide groove 2 via the guide block 16. At this time, the position of the magnet 17 also moves accordingly, and the attractive force applied by the positioning rod 9 disappears. Simultaneously, the positioning rod 9 retracts to the inner side of the adjusting seat 5 under the action of the return spring 8. Then, the extension rod 7 is pulled longitudinally. The longitudinal movement of the extension rod 7 causes the adjusting seat 5 to slide along the inner wall of the clamping tube 1. At this time, the adjusting seat 5 will drive the slider 6 to slide along the slide groove 4, thereby improving the stability of the adjusting seat 5 during longitudinal movement. After the adjusting seat 5 moves to the appropriate position, the positioning rod 9 will move to one side of the other positioning hole 3. At this time, the adjusting ring 15 is turned again, causing the magnet 17 to move back to one side of the positioning rod 9. Then, under the action of the magnet 17, one end of the positioning rod 9 will be re-entered into the inner side of the positioning hole 3 to achieve the positioning of the adjusting seat 5. The setting of the auxiliary sliding plate 10 can improve the stability of the positioning rod 9 during movement, which is convenient and quick, and has higher overall practicality.

[0038] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
