[0027] The following specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, and those skilled in the art can make non-creative contribution modifications to the embodiments according to the needs after reading the specification, but as long as in the utility model's right claim range all receive the patent law's protection.

[0028] The scheme is realized through the following technical means:

[0029] Embodiment: in the embodiment, a split assembly type pulling wool computer hosiery machine needle cylinder is given, which can realize accurate and stable connection between components, and can also conveniently and quickly disassemble and replace the components.

[0030] Specifically, the needle cylinder product mainly comprises a cylindrical needle cylinder body 1 for fixing the sock body and accommodating the installed knitting needle, the inside of the needle cylinder body 1 is formed with a cylindrical and vertically penetrating cavity, so that the needle cylinder body 1 is a cylindrical tube as a whole. A plurality of knitting needle guide grooves 101 are formed on the outer peripheral portion of the needle cylinder body 1, which extend along the axial direction and penetrate the upper and lower ends. The inner side of the upper end of the needle cylinder body 1 is provided with a sinker plate connecting and mounting member 3 for connecting and fixing the sinker plate, and the outer side at the same end position is fixedly provided with a sinker disc 2 component through a convenient mounting and dismounting clamping connection structure 4.

[0031] Specifically, the clamping connection structure 4 first comprises a circumferential clamping connection portion 401 which is arranged around the outer side of the end of the needle cylinder body 1 and protrudes outward, and the circumferential clamping connection portion 401 is in a horizontally arranged circular ring state. Correspondingly, the sinker disc 2 adopts a split structure, which mainly comprises a main body portion 201, a clamping connection mounting portion 203 and a locking connecting member 204. The inner side edge of the main body portion 201 is formed with a downward first clamping surface 2011, the inner side edge of the clamping connection mounting portion 203 is formed with an upward second clamping surface 2012, and the main body portion 201 and the clamping connection mounting portion 203 are provided with mounting holes 402 through which the locking connecting member 204 passes. The part structure can refer to the enlarged structural schematic view of the connection position given in the accompanying drawings Figure 2 The enlarged structural schematic view of the connection position is given, the aforementioned main body portion 201 is in a flat state, the inner side of which is in a circular ring shape, and the first clamping surface 2011 is matched with the upper surface of the circumferential clamping connection portion 401 formed on the needle cylinder body 1, and the aforementioned clamping connection mounting portion 203 is in an inverted horizontal state, and the second clamping surface 2012 formed thereon is matched with the lower surface of the circumferential clamping connection portion 401, and then the locking connecting member 204 is connected and fixed between the clamping connection mounting portion 203 and the main body portion 201 in the vertical direction, so that the sinker disc 2 is fixedly connected to the needle cylinder body 1 by clamping. For example, the enlarged structural schematic view of the connection position is given in the accompanying drawings Figure 2The structure of the body part 201 is taken as an example, the mounting hole 402 opened on the body part 201 is a kind of through hole with big upper and small lower, while the mounting hole 402 opened on the clamping connection mounting part 203 can adopt a kind of thread hole extending from top to bottom, corresponding to this, the locking connector 204 here is a kind of vertically upright setting fastening bolt.When the fastening bolt as the locking connector 204 is passed through the body part 201 from top to bottom, it can be drilled into the thread hole on the lower clamping connection mounting part 203 by rotating itself, so as to realize the locking connection and fixing between the two parts.Of course, in order to realize the more stable connection and fixing between the ring-shaped chuck plate 2 and the needle cylinder barrel 1, a plurality of fastening bolts need to be fixed and installed around the circumferential direction of the chuck plate 2 and on the same circumference.

[0032] As a preferred structure for reinforcing the connection between the chuck plate 2 and the needle cylinder barrel 1, an upper embedded clamping structure 5 can be formed between the first clamping surface 2011 and the upper surface of the circumferential clamping connection part 401, and a lower embedded clamping structure 6 can be formed between the second clamping surface 2012 and the lower surface of the circumferential clamping connection part 401. Figure 3 The given partial further enlarged view shows that a downwardly protruding annular part is formed on the first clamping surface 2011, and a downwardly recessed mounting clamping groove corresponding to the annular part is opened on the upper surface of the circumferential clamping connection part 401, so that when the first clamping surface 2011 is attached to the upper surface of the circumferential clamping connection part 401, the annular part can be embedded in the inside of the mounting clamping groove.Similarly, for the lower embedded clamping structure 6, an upwardly protruding annular part is formed on the second clamping surface 2012, and an upwardly recessed mounting clamping groove corresponding to the annular part is opened on the lower surface of the circumferential clamping connection part 401, and the annular part can also be inserted and mounted into the inside of the mounting clamping groove.In this structure, when the body part 201 and the clamping connection mounting part 203 are clamped and fixed on the aforementioned circumferential clamping connection part 401 by the fastening bolt as the locking connector 204, the needle cylinder barrel 1 can further provide a horizontal resisting force for preventing the chuck plate 2 from deflecting on the basis of the vertical clamping force of the needle cylinder barrel 1 on the chuck plate 2, so that the positioning connection of the chuck plate 2 is more stable and reliable.

[0033] The inventor considers that, since the Gorkon disk 2 has a large size and weight, and needs to utilize several step surfaces formed thereon during operation. Under this structure, the Gorkon disk 2 will have a problem of slipping during stacking and transportation, not only occupying more space, but also easily causing damage due to collision. Therefore, in further preferred embodiments, the main body part 201 is designed as a split structure and connected and fixed by the split connecting part 202. This part structure can also be referred to the structure shown in the accompanying drawings Figure 3 The structure diagram shows that the fastening bolt of the seat split connecting part 202 is locked and fixed by simultaneously penetrating the two parts from top to bottom, thereby completing the assembly of the main body part 201 of the Gorkon disk 2. Of course, for Gorkon disks 2 of different sizes, the main body part 201 can be further divided into multiple parts and then connected and fixed.

[0034] For the foregoing Gorkon piece connecting and mounting part 3, the structure mainly includes a supporting and connecting part 301 formed in a circular ring shape on the outer side, used for abutting and fitting with the upper surface of the end part of the needle cylinder body 1, and an inner locking and connecting part 302 formed in an inclined shape extending inward and downward on the inner side of the Gorkon piece connecting and mounting part 3. Corresponding to the inner locking and connecting part 302 here, a step surface corresponding to the inclination of the foregoing inner locking and connecting part 302 is formed on the inner side of the end part of the needle cylinder body 1. Under this structure, a bolt part can be penetrated from the inside to the outside of the inner locking and connecting part 302, and the inner wall surface of the needle cylinder is locked and fixed, thereby completing the installation and fixation of the split assembly type Gorkon computer sock machine needle cylinder.

[0035] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
