Description

Technical Field

[0001] This utility model relates to the field of cable reel technology, and in particular to a cable reel with adjustable volume. Background Technology

[0002] A cable reel is a device used for storing, transporting, and installing cables. It is commonly used in the power industry, power construction projects, and industrial and mining enterprises. Its main function is to keep the cable neatly wound, preventing damage during use, and facilitating quick unwinding and retraction of the cable.

[0003] Currently, most mainstream cable reels on the market adopt an integrated structure design with a fixed volume, which can only be used for cable winding operations of a specific length. When faced with the need to wind up ultra-long cables, the existing reels cannot meet the requirements due to capacity limitations, and larger models must be replaced to complete the operation. This design leads to significant limitations in selection and application scenarios. Utility Model Content

[0004] This utility model relates to an adjustable-volume cable reel, which solves the problem that existing cable reels generally adopt an integrated structure design with a fixed volume, which can only be used for cable winding operations of a specific length. When faced with the need to wind up ultra-long cables, existing reels cannot meet the requirements due to capacity limitations, and a larger specification model must be replaced to complete the operation, which has significant limitations.

[0005] In a first aspect, this utility model provides a cable reel with adjustable volume, specifically comprising: an inner cylinder, a left retaining ring, an outer cylinder, a right retaining ring, a rotating cylinder, and bolts; the left retaining ring is fixedly connected to the left end of the inner cylinder, the outer cylinder is fitted onto the outside of the inner cylinder, and the right retaining ring is fixedly connected to the right end of the outer cylinder; the rotating cylinder is connected to the inner side of the left retaining ring, and the rotating cylinder is connected to the outside of the outer cylinder; two bolts are connected to the left end of the rotating cylinder, and the bolts are connected to the inside of the left retaining ring.

[0006] Furthermore, the outer side of the inner cylinder slides in contact with the inner side of the outer cylinder, allowing the movement of the outer cylinder to be adjusted according to the required cable winding length, thereby changing the distance between the left and right retaining rings and thus altering the volume of the cable reel.

[0007] Furthermore, a guide groove is provided around the outer side of the inner cylinder, and a guide protrusion is provided around the inner side of the outer cylinder. The guide protrusion is slidably connected to the guide groove provided in the inner cylinder. The guide protrusion and the guide groove slide together to guide the movement of the outer cylinder and prevent the outer cylinder from twisting.

[0008] Furthermore, the rotating cylinder is rotatably connected to the left retaining ring, and the inner side of the rotating cylinder is in sliding contact with the outer side of the outer cylinder.

[0009] Furthermore, the rotating cylinder has two spiral oblique holes arranged around its interior, and the outer cylinder has two sliders arranged around its exterior. The sliders are rhomboid in shape and are slidably connected to the spiral oblique holes in the rotating cylinder. The sliders and spiral oblique holes are slidably engaged. By rotating the rotating cylinder, the rotating cylinder drives the outer cylinder to move and adjust, thereby changing the distance between the left and right retaining rings.

[0010] Furthermore, the rotating cylinder has two symmetrically arranged inner positioning holes on its exterior, and the left retaining ring has an outer positioning hole surrounding it. The inner positioning holes are connected to the outer positioning hole of the left retaining ring.

[0011] Furthermore, the bolt is inserted into the locating inner hole and the locating outer hole in a connected state. The bolt end is threaded with a nut, which contacts the outer side of the left retaining ring. After the distance between the left and right retaining rings is adjusted, the locating inner hole and the locating outer hole are in a connected state. The bolt is then inserted through the locating inner hole and the locating outer hole, and the nut is tightened. The rotating cylinder is fixed by the bolt to ensure the stability of the outer cylinder.

[0012] This utility model provides a cable reel with adjustable volume, which has the following beneficial effects:

[0013] In use, the guide protrusion and guide groove adopt a sliding fit design, which can effectively guide the outer cylinder to move smoothly and prevent the outer cylinder from twisting during operation. According to the actual required cable winding length, the moving position of the outer cylinder can be flexibly adjusted, thereby adjusting the distance between the left and right retaining rings, thereby changing the storage volume of the cable reel and fully meeting the winding needs of cables of different lengths.

[0014] In addition, the slider and the spiral oblique hole form a sliding fit relationship; when the rotating cylinder is rotated, the rotating cylinder will drive the outer cylinder to make a moving adjustment action, thereby realizing the flexible change of the distance between the left retaining ring and the right retaining ring, and significantly improving the ease of operation.

[0015] In addition, after adjusting the distance between the left and right retaining rings, ensure that the inner and outer positioning holes are precisely aligned and connected. Pass the bolts through the inner and outer positioning holes in sequence and tighten the matching nuts. Use the bolts to securely fix the rotating cylinder, which can effectively maintain the stability of the outer cylinder and thus ensure that the distance between the left and right retaining rings remains stable.

A guide groove 11 is provided around the outer side of the inner cylinder 1, and a guide protrusion 31 is provided around the inner side of the outer cylinder 3. The guide protrusion 31 is slidably connected to the guide groove 11 provided in the inner cylinder 1.

[0032] Using the above technical solution, the guide protrusion 31 and the guide groove 11 slide together to guide the movement of the outer cylinder 3, preventing the outer cylinder 3 from twisting. The movement of the outer cylinder 3 can be adjusted according to the required cable length, changing the distance between the left retaining ring 2 and the right retaining ring 4, thereby changing the volume of the cable reel and better meeting the needs of cable reeling of different lengths.
