[0002] Traditional vertical wire feeding racks typically have a central, upward-extending column. The column's height is significant, preventing the wires mounted on it from tipping over. However, due to the column's height, lifting and loading the wires requires a large lifting height, resulting in slow loading speed and poor overall performance. Therefore, this invention proposes a wire feeding rack for nut production. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present utility model relates to a wire feeding rack for nut production, including a fixed base, a movable base located above the fixed base is rotatably connected to the fixed base, and the movable base is provided with a plurality of curved arm assemblies arranged in a circular array around an axis. The curved arm assembly includes an outer square tube and an inner square tube extending in the circumferential direction. The inner square tube is slidably connected inside the outer square tube. The end of the outer square tube facing away from the inner square tube is close to the outer edge of the movable base, and the end of the inner square tube facing away from the outer square tube is far away from the outer edge of the movable base. The outer square tube is fixedly connected to the movable base.

[0005] The present invention is further configured such that: a row of positioning holes are provided on the inner square tube and arranged at equal intervals along its extension trajectory, wherein at least one of the positioning holes is matched with a ball-head plunger, the ball-head plunger is provided on the outer square tube, and the ball head of the ball-head plunger is embedded in the positioning hole.

[0006] The present invention is further configured such that: the inner side of the outer square tube is provided with a first limiting part, and the outer side of the inner square tube is provided with a second limiting part that matches the first limiting part.

[0007] The present invention is further configured such that: the second limiting part is provided at one end of the inner square tube, and the other end of the inner square tube is provided with a third limiting part.

[0008] The present invention is further configured to include a spoke ring connected to all the outer square tubes, the spoke ring being located above the outer square tubes and close to the outer edge of the movable base.

[0009] The present invention is further configured such that: a main shaft is rotatably connected to the center of the movable base, the bottom of the main shaft is connected to the fixed base, guide wheels are arranged around the fixed base, and the bottom of the movable base presses against the wheel surface of the guide wheels.

[0010] The present invention is further configured to include a support ring connected to all the outer square tubes, the support ring being located below the outer square tubes.

[0011] In summary, the present invention has the following beneficial effects: The wire feeding rack for nut production involved in the present invention reduces the overall height of the crank arm assembly by manually retracting the inner square tube, so that the loaded wire can be loaded without being lifted too high. The lifting height is small, the loading speed is fast, the overall function is complete, and the practicality is strong. Attached Figure Description

However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] Example 1

[0018] See Figures 1 to 3 As shown, the wire feeding rack for nut production involved in this embodiment includes a fixed base 1, and a movable base 2 located above the fixed base 1 is rotatably connected to the fixed base 1. The movable base 2 is provided with a plurality of curved arm assemblies arranged in a circular array around an axis. The curved arm assembly includes an outer square tube 3 and an inner square tube 4 extending in the circumferential direction. The inner square tube 4 is slidably connected inside the outer square tube 3. The end of the outer square tube 3 facing away from the inner square tube is close to the outer edge of the movable base, and the end of the inner square tube 4 facing away from the outer square tube is far away from the outer edge of the movable base. The outer square tube 3 is fixedly connected to the movable base 2.

[0019] Furthermore, a row of positioning holes (not shown) are provided on the inner square tube 4, arranged at equal intervals along its extension trajectory, wherein at least one of the positioning holes is matched with a ball-head plunger 5, the ball-head plunger 5 is provided on the outer square tube 3, and the ball head of the ball-head plunger 5 is embedded in the positioning hole.

[0020] Furthermore, the inner side of the outer square tube 3 is provided with a first limiting part 6, and the outer side of the inner square tube 4 is provided with a second limiting part 7 that matches the first limiting part.

[0021] Furthermore, the second limiting part 7 is provided at one end of the inner square tube 4, and the other end of the inner square tube 4 is provided with a third limiting part 8.

Guide wheels 11 are arranged around the fixed base 1, and the bottom of the movable base 2 presses against the wheel surface of the guide wheels 11.

[0023] In this implementation plan, the wire feeding frame is first deformed to the following extent: Figure 2 As shown, all the inner square tubes 4 on the articulated boom assembly are retracted into the outer square tube 3. The overall height of the cable tray (or the articulated boom assembly) is reduced, allowing the cable on the articulated boom assembly to be lifted to a slightly lower height for loading. After loading, the inner square tubes 4 are manually pulled out from the outer square tube 3 until they deform as shown. Figure 1 The state shown.

[0024] The positioning hole, in conjunction with the ball-head plunger 5, serves as a positioning feature for the inner square tube 4 when it extends or retracts relative to the outer square tube 3.

[0025] The first limiting part 6, the second limiting part 7 and the third limiting part 8 are provided to limit the extension and retraction of the inner square tube 4 relative to the outer square tube 3.
