[0002] As a type of mechanical equipment specifically designed for producing various types of socks, one of the key components of a sock knitting machine is the cylinder. The main function of the cylinder is to support and arrange the needles of the sock knitting machine, ensuring that the needles can stably and accurately perform the work of knitting socks during the knitting process.

[0003] In the prior art, for example, the utility model patent CN222455429U discloses a detachable intelligent sock knitting machine needle cylinder, which makes the needle cylinder easy to disassemble by setting up a clamp, bolts and nuts, protrusions and notches. However, in practical applications, it has been found that the use of clamps not only occupies the external space of the needle cylinder, but also requires the use of tools such as wrenches and screwdrivers to disassemble and assemble the clamps, which greatly restricts the disassembly and assembly of the clamps and cannot meet the needs of a single person to disassemble and assemble the needle cylinder independently. Therefore, a detachable sock knitting machine needle cylinder is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a detachable needle cylinder for a sock knitting machine to solve the problems mentioned in the background art.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-3 The diagram shows a detachable needle cylinder for a sock knitting machine, comprising an upper needle cylinder 100 and a lower needle cylinder 101, and a hollow frame 102. The hollow frame 102 is fixedly connected to the bottom of the inner side of the upper needle cylinder 100 and is hollow with both ends connected. A positioning slot 103 is formed at the top of the inner side of the lower needle cylinder 101, and the outer wall of the hollow frame 102 is movably connected to the inner side of the positioning slot 103. A mounting slot 104 is formed at the top of the inner side of the lower needle cylinder 101 and communicates with the positioning slot 103. A limit locking block 105 is movably connected within the mounting slot 104, and the top of the limit locking block 105 is connected to the hollow frame 101. 02. The central movable insertion part, the limiting locking block 105 is sickle-shaped with a wider top and narrower bottom. The side of the limiting locking block 105 near the upper syringe 100 is an arc surface. A return spring 107 is provided in the mounting groove 104. One end of the return spring 107 is fixedly connected to the side wall of the limiting locking block 105, and the other end of the return spring 107 is fixedly connected to the inner wall of the mounting groove 104. In this embodiment, the return spring 107 provides an elastic thrust for the limiting locking block 105 to automatically return, so that the protruding part of the top of the limiting locking block 105 can be automatically inserted into the hollow position of the hollow frame 102, thereby achieving the goal of locking the hollow frame 102. The limiting lock at the positioning slot 103 position allows the upper syringe 100 and lower syringe 101 to be joined. When the hollow frame 102 is inserted into the positioning slot 103, the limiting lock block 105 is inserted into the hollow part of the hollow frame 102 to lock it in place, thus fixing the upper syringe 100 and lower syringe 101 in their joined positions. The limiting lock block 105 is sickle-shaped, and its top sidewall facing the upper syringe 100 is an arc surface. This allows the hollow frame 102 to automatically compress the limiting lock block 105 when inserted into the positioning slot 103, enabling the limiting lock block 105 to automatically retract to its installation position. The hollow frame 102 can be inserted into the positioning slot 103 for positioning without affecting the normal insertion of the hollow frame 102 into the positioning slot 103. Furthermore, the elastic compression of the return spring 107 can drive the limit locking block 105 to automatically insert into the hollow frame 102 to achieve automatic locking. This makes the splicing and locking operation between the upper syringe 100 and the lower syringe 101 more convenient. To enhance the stability of the splicing and locking between the upper syringe 100 and the lower syringe 101, multiple hollow frames 102, positioning slots 103, and mounting slots 104 can be arranged in an array to meet the multi-point locking and fixing between the upper syringe 100 and the lower syringe 101.

[0025] Furthermore, the mounting groove 104 has an L-shaped cross-section, narrower at the top and wider at the bottom. The bottom of the mounting groove 104 extends towards the inner side of the upper syringe 100 and communicates with the inner wall of the upper syringe 100. A toggle assembly is provided at the bottom of the mounting groove 104 near the inner wall of the upper syringe 100. The toggle assembly is used to drive the limiting lock block 105 to move towards the inner wall of the mounting groove 104. The bottom of the mounting groove 104 extends towards the inner side of the lower syringe 101, allowing the toggle assembly to be installed, thereby driving the movement of the locking block 105. The limiting lock block 105 moves inward toward the mounting groove 104 and disengages from the hollow frame 102, thus unlocking the hollow frame 102 and the limiting lock block 105. This makes it easier for the user to remove the upper syringe 100 from the top of the lower syringe 101, making it more convenient to remove the upper syringe 100 from the top of the lower syringe 101. At the same time, the actuating component does not require tools to drive it; the user can drive it manually, making the operation simpler and more convenient, highly adaptable, and not limited by the environment.

[0026] The actuating assembly includes an actuating ring 108, which is rotatably connected to the end of the mounting groove 104 near the inner wall of the upper syringe 100. Multiple extrusion protrusions 109 are fixedly connected in an array to the outer peripheral wall of the actuating ring 108. Multiple return springs 107 are located on the side of the extrusion protrusions 109 near the limiting lock block 105, and each return spring 107 is fixedly connected to the side wall of the limiting lock block 105 at a corresponding position. The sides of the extrusion protrusions 109 and the arc-shaped protrusions 106 are both arc-shaped. The rotation driven by the actuating ring 108 in the actuating assembly synchronously drives the multiple extrusion protrusions 109 to rotate. Combined with the inclined contact between the extrusion protrusions 109 and the arc-shaped protrusions 106, the protrusions can be brought to the opposite side of the arc-shaped protrusions. The pressing action of the arc-shaped protrusion 106 pushes the arc-shaped protrusion 106 to move horizontally. Since the arc-shaped protrusion 106 is fixed to the limiting lock block 105, the limiting lock block 105 can be driven to move horizontally by the arc-shaped protrusion 106. In this way, the limiting lock block 105 can be driven to move horizontally by manually turning the toggle ring 108, thereby unlocking the limiting lock block 105 and the hollow frame 102. This not only eliminates the need for other auxiliary tools when unlocking and disassembling, but also allows the user to drive the unlocking operation between multiple limiting lock blocks 105 and multiple hollow frames 102 simply by turning the toggle ring 108. It eliminates the need to unlock each hollow frame 102 and the limiting lock block 105 one by one, making the unlocking and disassembly operation more convenient and efficient.

[0027] In addition, the actuating ring 108 has integrally formed annular protrusions on both the upper and lower sides, and multiple grooves are spaced apart on the side of the actuating ring 108 away from the extrusion protrusion 109. It should be noted that the inner wall of the lower syringe 101 and the position at the end of the mounting groove 104 are interconnected arc-shaped grooves, which can satisfy the rotational installation of the actuating ring 108. Furthermore, the annular protrusions on the actuating ring 108 can form a sliding engagement with the inner walls of the upper and lower sides of the mounting groove 104, thus limiting the actuating ring 108 in the mounting groove 104, so that the actuating ring 108 can only rotate radially. The grooves on the side of the actuating ring 108 away from the mounting groove 104 facilitate the formation of a force point between the user's hand and the actuating ring 108, thereby making it easier for the user to rotate the actuating ring 108 and further improving the convenience of operation.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
