Detailed Implementation

[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-6 As shown, this embodiment discloses a circular syringe lifting device, including a base plate 1 and a connecting sleeve 2. The upper end surface of the base plate 1 can hold a circular syringe 101. The base plate 1 is a circular plate with three guide grooves 11 arranged in a circular array. The base plate 1 includes three limiting rods 12 that can move radially along the base plate 1. The base plate 1 includes multiple lead screws 13. The guide grooves 11 extend radially along the base plate 1, and each guide groove 11 is fitted with a lead screw 13. The lead screw 13 includes two parts that are rotatably connected to the base plate 1. One end of the lead screw 13 extends out of the side wall of the base plate 1, and a handle is installed at the end of the lead screw 13 extending out of the side wall of the base plate 1 to facilitate rotation of the lead screw 13. The lead screw 13 extends along the length direction of the guide groove 11. The limiting rod 12 includes a connecting block 121 and a stop rod 122. The connecting block 121 is located on the guide groove 11. Inside the guide groove 11, the connecting block 121 is threadedly connected to the lead screw 13. The connecting block 121 can move along the guide groove 11. The stop rod 122 is located at the upper end of the connecting block 121 and abuts against the inner wall of the circular knitting machine syringe 101. When the circular knitting machine syringe 101 is placed on the upper surface of the base plate 1, the position of the limiting rod 12 in the guide groove 11 can be adjusted by rotating the lead screw 13. The limiting rod 12 can abut against the inner wall of the circular knitting machine syringe 101. The circular knitting machine syringe 101 is limited and opened by the limiting rods 12 in three directions. The stop rod 122 is a circular rod. The circular outer surface can prevent scratches on the inner wall of the circular knitting machine syringe 101. The limiting rod 12 supports the circular knitting machine syringe 101 on the inner side and will not touch the needle groove opened on the outer wall of the circular knitting machine syringe 101, thus preventing the circular knitting machine syringe 101 from shifting during hoisting.

[0024] The base plate 1 includes a central column 14, which is located on the upper surface of the base plate 1 and at the center of the base plate 1. The central column 14 includes a column cap 141 and a column rod 142. The column rod 142 is fixedly installed on the base plate 1, and the column cap 141 is located at the upper end of the column rod 142. The central column 14 can be inserted into the connecting sleeve 2. The connecting sleeve 2 is detachably connected to the central column 14. The top of the connecting sleeve 2 is provided with a lifting ring 25, which is connected to the crane. The connecting sleeve 2 and the central column 14 realize the detachable connection between the base plate 1 and the crane.

[0025] like Figure 4 As shown, the connecting sleeve 2 includes a housing 21. The lower end face of the housing 21 is provided with a slot 211, into which the central post 14 can be inserted. The side wall of the housing 21 is provided with a mounting groove 212, on which a locking block 22 is mounted. At least two locking blocks 22 are provided. In order to make the locking block 22 more stable in limiting the base plate 1, the locking block 22 can slide along the mounting groove 212. A part of the locking block 22 can extend out of the inner wall of the housing 21. A spring 23 is installed in the mounting groove 212. The first end of the spring 23 extends into the locking block 22. An outer cover 24 is installed at the end of the mounting groove 212 away from the slot 211. The other end of the spring 23 extends into the outer cover 24. The spring 23 supports the locking block 22 to extend out of the mounting groove 212, so that the locking block 22 can be reset and remain extended.

[0026] The locking block 22 can be engaged with the lower end of the column cap 141. When the connecting sleeve 2 approaches the central column 14 from top to bottom, the locking block 22 abuts against the column cap 141. Since the lower end face of the part of the locking block 22 that extends out of the mounting groove 212 is an arc surface and the upper end face of the column cap 141 is a hemispherical surface, the locking block 22 will be gradually abutted into the mounting groove 212. When the locking block 22 passes the column cap 141, it is extended by the action of the spring 23. At this time, the locking block 22 forms a limit on the central column 14, and the crane can lift the base plate 1 to transport the circular knitting machine cylinder 101.

[0027] like Figure 5 As shown, after the circular knitting needle cylinder 101 is hoisted to the designated area, the crane lowers the connecting sleeve 2, and the movable ring 15 is installed on the column rod 142. The movable ring 15 is sleeved on the column rod 142 and can slide along the column rod 142. The cross-section of the movable ring 15 is triangular, and the upper and lower end faces of the movable ring 15 are inclined. The locking block 22 is pressed inward by the upper end face of the movable ring 15 until it exceeds the maximum diameter of the movable ring 15. The maximum diameter of the column cap 141 is the same as the maximum diameter of the movable ring 15, and it can correspond to the slot 211 and the locking block 22. Due to the action of the spring 23, the locking block 22 resets and pushes the movable ring 15 upward. Figure 6As shown, when the connecting sleeve 2 is lifted upwards, the movable ring 15 rises together. The lower end face of the column cap 141 is provided with an annular groove 1411, which can accommodate part of the movable ring 15. When the upper part of the movable ring 15 is inserted into the annular groove 1411, the edge of the maximum diameter of the column cap 141 corresponds to the edge of the maximum diameter of the movable ring 15. At this time, if the connecting sleeve 2 is lifted upwards, the locking block 22 can pass over the column cap 141, and the connecting sleeve 2 can be disengaged from the central column 14. The connection and disassembly are very convenient.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
