Description

Technical Field

[0001] This utility model relates to a cable reel structure, and more particularly to an anti-sway cable reel structure, belonging to the field of cable reel technology. Background Technology

[0002] Currently, in order to facilitate the winding of the cable reel, a single-sided support method is used in the use of portable cable reels. However, due to the insufficient rigidity of the single-sided support and improper tension control during manual winding, the cable may shift left and right on the reel surface or have uneven stacking thickness. This can cause swaying when the cable is unloaded, resulting in friction between the cable and the reel. In addition, during long-term use, insufficient lubrication of the bearings can lead to wear, which can also cause rotational swaying.

[0003] To address this issue, an anti-sway cable reel structure was designed. Utility Model Content

[0030] Example 1

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes an anti-sway cable reel structure, including a herringbone side frame 1, a chamfered base frame 101 horizontally fixed between the two ends of the bottom of the herringbone side frame 1, a shaft 102 fixedly installed at the middle position of the inner side of the herringbone side frame 1, bearings 103 installed at both ends of the shaft 102, and a cable reel 104 fixed to the outside of the bearings 103.

[0032] A limiting ring 2 is provided at the end of the spool 104 away from the herringbone side frame 1. A groove 3 is provided on the inner side of the limiting ring 2. The outer end face of the spool 104 is stuck inside the groove 3, and the spool 104 and the limiting ring 2 are rotatably connected. The groove 3 is annular, with a depth of 5-8mm and a width of 10-15mm, which is adapted to the size of the outer end face of the spool 104. A support rod 4 is fixed between the bottom end of the limiting ring 2 and the C-shaped base frame 101.

[0033] A lubrication mechanism 5 for lubricating the bearing 103 is provided at the middle position of the outer side of the herringbone side frame 1.

[0034] During use, the spool 104 rotates around the shaft 102. The herringbone side frame 1 supports one end of the spool 104 via the shaft 102, while the other end of the spool 104 is located inside the limiting ring 2. The limiting ring 2 supports the other end of the spool 104, and the simultaneous limiting support at both ends improves the stability of the support and effectively limits the spool 104, preventing swaying during rotation. In addition, during outdoor use, if the bearing 103 makes abnormal noise, the lubrication mechanism 5 can be used to inject lubricant in time to lubricate the bearing 103 and reduce the wear of the bearing 103.

[0035] Example 2

[0036] The solution in Example 1 will be further described below with reference to its specific working method.

[0037] like Figure 1 As shown, in a preferred embodiment, based on the above method, the top of the herringbone side frame 1 spans between the two ends of the reel 104, and the herringbone side frame 1 is fixedly connected to the top of the limiting ring 2. The connection is fixed by welding to improve the structural strength. The top of the herringbone side frame 1 is provided with a handle 105. The top of the limiting ring 2 is fixed by the herringbone side frame 1 to improve the overall rigidity of the support. The presence of the handle 105 makes it convenient to carry and move.

[0038] like Figure 3 As shown, in a preferred embodiment, based on the above method, furthermore, rotating rollers are evenly rotatably installed between the two sides of the groove 3, and the rotating rollers are distributed in a circular array. The rotating rollers are in contact with the outer end face of the wire spool 104. During the rotation of the wire spool 104, the rotating rollers are driven to rotate, and there will be no wear with the inner side of the groove 3. The rotation of the wire spool 104 is more labor-saving. The rotating rollers are made of stainless steel and have a diameter of 8-12mm. They are evenly installed on both sides of the groove 3 through miniature bearings. The axis of the rotating rollers is parallel to the axis of the wire spool 104. The contact pressure between the outer surface of the rotating rollers and the outer end face of the wire spool 104 is 0.1-0.3N, and the number is 6-12. The included angle between adjacent rotating rollers is 30°-60°.

[0039] like Figure 1 As shown, in a preferred embodiment, based on the above method, a sealing ring is further provided at the outer end of the shaft hole on the coil 104, and the inner ring of the sealing ring fits against the outer side of the shaft 102. The use of the sealing ring can form a seal at the outer end of the shaft hole, preventing dust from entering the interior of the shaft hole and affecting the rotation of the bearing 103. The sealing ring is made of nitrile rubber with a Shore hardness of 60-70HA. The inner ring diameter is 0.5-1mm smaller than the outer diameter of the shaft 102. It is installed at the outer end of the shaft hole of the coil 104 by interference fit to form a radial seal, and the dustproof level reaches IP54.

[0040] like Figure 4 As shown, in a preferred embodiment, based on the above method, the lubrication mechanism 5 further includes a mounting block 501, an external threaded tube 502, a storage cylinder 503, an extrusion hole 504, and an extrusion assembly. The mounting block 501 is fixed on the herringbone side frame 1. The external threaded tube 502 is fixed on the outside of the mounting block 501. The storage cylinder 503 is threaded onto the external threaded tube 502. The end of the storage cylinder 503 is provided with an extrusion assembly. The shaft 102 has an extrusion hole 504 that communicates with the inside of the storage cylinder 503. The outlet at the top of the extrusion hole 504 communicates with the outside of the shaft 102.

[0041] When in use, fill the inside of the storage cylinder 503 with grease. The storage cylinder 503 has a capacity of 50-100ml and is made of transparent plastic to facilitate observation of the remaining grease. It is filled with lithium-based grease. Then, install the storage cylinder 503 onto the external screw tube 502. When the bearing 103 needs to be lubricated, adjust the extrusion assembly to squeeze the grease out of the extrusion hole 504. After the grease is discharged from the outlet, apply it to the bearing 103 for lubrication.

[0042] like Figure 4 As shown, in a preferred embodiment, based on the above method, the discharge outlets at the top of the extrusion orifice 504 are all inclined toward the bearing 103, and there are two sets of discharge outlets at the top of the extrusion orifice 504. After the grease is extruded at an incline, it can be directly applied to the bearing 103, resulting in better lubrication. The diameter of the extrusion orifice 504 is 2-3 mm, and the inclination angle of the top discharge outlet is 30°-45°.

[0043] like Figure 4As shown, in a preferred embodiment, based on the above method, the extrusion assembly further includes a piston 505, an inner spiral tube 506, a screw 507, and an adjusting block 508. The piston 505 is slidably disposed inside the storage cylinder 503. The screw 507 is rotatably mounted at the end of the storage cylinder 503. The inner spiral tube 506 is threaded onto the screw 507. The inner spiral tube 506 is fixed to the side of the piston 505. The adjusting block 508 is fixed at the outer end of the screw 507. The inner spiral tube 506 slides horizontally at the end of the storage cylinder 503.

[0044] When lubricating bearing 103, first rotate adjusting block 508 to control the rotation of screw 507. Since the inner screw tube 506 can only move horizontally inside storage cylinder 503, when screw 507 rotates, control the inner screw tube 506 to drive piston 505 to move towards mounting block 501, apply extrusion pressure to the grease, and squeeze out the grease. The screw pitch of screw 507 is 1-2mm. When adjusting block 508 rotates one revolution, piston 505 moves a distance of 1-2mm, corresponding to a grease extrusion amount of 0.5-1ml.

[0045] Example 3

[0046] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0047] During use, the coil 104 rotates around the shaft 102. The herringbone side bracket 1 supports one end of the coil 104 via the shaft 102, while the other end of the coil 104 is located inside the limiting ring 2. The limiting ring 2 supports the other end, and the simultaneous limiting support at both ends improves the stability of the support and effectively limits the coil 104, preventing swaying during rotation. In addition, if the bearing 103 makes abnormal noise during outdoor use, the rotating adjusting block 508 controls the rotation of the screw 507. Since the inner screw tube 506 can only move horizontally inside the storage cylinder 503, when the screw 507 rotates, it controls the inner screw tube 506 to drive the piston 505 to move towards the mounting block 501, applying pressure to the grease, squeezing the grease into the extrusion hole 504, and discharging it from the outlet to lubricate the bearing 103.

[0048] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
