Description

Technical Field

[0001] This utility model relates to the field of cable storage technology, specifically to an adjustable-length cable reel. Background Technology

[0002] A cable reel is a common tool used to store cables and has wide applications in daily life and industrial production.

[0003] Currently, traditional cable reels are usually of fixed length, which limits the length of cables they can hold; when the length of the cable to be stored is short, using a larger size cable reel will result in wasted space.

[0004] When the cable is long, a fixed-length reel cannot meet the storage needs, resulting in the cable being tangled and messy. This not only affects the lifespan of the reel but also causes inconvenience in the use and management of the cable. Utility Model Content

[0005] The purpose of this invention is to provide a length-adjustable reel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable length reel, comprising two fixed reels and two center blocks installed between the two fixed reels, wherein a first bearing seat is installed between one of the center blocks and a fixed reel, and an adjustment mechanism is installed between the two center blocks for adjusting the distance between the two fixed reels;

[0007] The adjustment mechanism includes several strip grooves formed on the surfaces of the two central blocks. A fixed housing is fixedly installed on one side of each of the strip grooves, and several strip rods are slidably installed between the fixed housings. The strip rods are slidably connected to the strip grooves.

[0008] An adjustment assembly is installed between the two center blocks to adjust the distance between them.

[0009] Preferably, the adjustment assembly includes two through holes formed inside a central block, and a threaded sleeve is fixedly installed on one side of the central block and on one side of the two through holes.

[0010] Two second bearing seats are rotatably mounted on one side of the other central block. A screw is rotatably mounted inside the second bearing seat, and one end of the screw passes through the threaded sleeve and extends into the interior of the through hole. The screw and the threaded sleeve are connected by a thread.

[0011] Preferably, one of the fixed disks has an internal mounting cavity, and one end of the screw passes through the central block and the fixed disk in sequence and extends into the interior of the mounting cavity;

[0012] A gear is fixedly installed at one end of the screw inside the mounting cavity, and a gear ring is fixedly installed inside the mounting cavity. The gear ring and the gear are meshed together.

[0013] Preferably, each of the fixed housings has a slide rail fixedly installed inside, and both sides of the strip rod are provided with slide grooves that are adapted to the slide rails. The strip rod is slidably connected to the slide rails through the slide grooves.

[0014] Preferably, a plurality of threaded holes are formed on the surface of one of the gears, and a bolt is installed through one side of one of the fixed disks. The end of the bolt located inside the fixed disk passes through the mounting cavity and the gear in sequence and is threadedly connected to the gear.

[0015] Preferably, each of the two central blocks has an installation hole inside, and a limit strip is fixedly installed around the perimeter of the installation hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By utilizing the adjustment component, when winding cables of different lengths, the fixed disc is rotated forward or backward through the rotational connection between the first bearing seat and the fixed disc. While the fixed disc rotates, its internal mounting cavity rotates synchronously. The mounting cavity is connected to two gears, which drives the screw to rotate synchronously. The screw is then connected to the threaded sleeve, which drives another center block to move, thereby increasing or decreasing the distance between the two center blocks and changing the length of the fixed disc and the center block. This allows for easy adjustment of the overall length of the fixed disc and the center block according to the length of the cable, providing the advantage of winding the cable.

[0018] 2. Furthermore, during the movement of the two center blocks, the several slots on the surface of the center blocks can block the space between the two center blocks through several strip rods, so that the cable can be evenly wound on the surface of the two center blocks, avoiding the occurrence of height differences on the surface of the center blocks, which would affect the uniformity of cable winding.

[0026] 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.

[0027] Please see Figures 1-6 The present invention provides a technical solution: an adjustable length reel, comprising two fixed reels 1 and two center blocks 2 installed between the two fixed reels 1, wherein a first bearing seat 3 is installed between one center block 2 and the fixed reel 1, and an adjustment mechanism 4 is installed between the two center blocks 2 for adjusting the distance between the two fixed reels 1.

[0028] The adjustment mechanism 4 includes several strip grooves 41 formed on the surfaces of the two central blocks 2. A fixed housing 42 is fixedly installed on one side of each of the strip grooves 41, and several strip rods 43 are slidably installed between the fixed housings 42. The strip rods 43 are slidably connected to the strip grooves 41.

[0029] An adjustment component 44 is installed between the two center blocks 2 to adjust the distance between the two center blocks 2.

[0030] Reference Figure 2 , Figure 4 as well as Figure 5As shown, the adjustment assembly 44 includes two through holes 441 opened inside a central block 2. A threaded sleeve 442 is fixedly installed on one side of the central block 2 and on one side of the two through holes 441. Two second bearing seats 443 are rotatably installed on one side of the other central block 2. A screw 444 is rotatably installed inside the second bearing seat 443, and one end of the screw 444 passes through the threaded sleeve 442 and extends into the interior of the through hole 441. The screw 444 and the threaded sleeve 442 are threadedly connected. A mounting cavity 445 is opened inside a fixed disk 1. One end of the screw 444 passes through the central block 2 and the fixed disk 1 in sequence and extends into the interior of the mounting cavity 445. A gear 446 is fixedly installed on one end of the screw 444 inside the mounting cavity 445. A gear ring 447 is fixedly installed inside the mounting cavity 445. The gear ring 447 and the gear 446 are meshed.

[0031] In this embodiment, when winding cables of different lengths, the fixed disk 1 is rotated forward or backward through the rotational connection between the first bearing seat 3 and the fixed disk 1. While the fixed disk 1 is rotating, its internal mounting cavity 445 rotates synchronously. The mounting cavity 445 is meshed with two gears 446, which drives the screw 444 to rotate synchronously. Then, the screw 444 is threadedly connected to the threaded sleeve 442 to drive another center block 2 to move, thereby increasing or decreasing the distance between the two center blocks 2 and changing the length of the fixed disk 1 and the center block 2. This makes it easy to adjust the overall length of the fixed disk 1 and the center block 2 according to the length of the cable, which is an advantage for winding the cable.

[0032] Reference Figure 2 as well as Figure 3 As shown, a slide rail 45 is fixedly installed inside several fixed housings 42, and slide grooves adapted to slide rails 45 are provided on both sides of the strip rod 43. The strip rod 43 is slidably connected to the slide rail 45 through the slide grooves.

[0033] In this embodiment, the stability of the center block 2 during its movement can be further improved.

[0034] Reference Figure 4 as well as Figure 6 As shown, a gear 446 has several threaded holes 46 on its surface, and a bolt 47 is installed through one side of a fixed disk 1. One end of the bolt 47 located inside the fixed disk 1 passes through the mounting cavity 445 and the gear 446 in sequence and is threadedly connected to the gear 446.

[0035] In this embodiment, after the length of the fixed plate 1 and the center block 2 is adjusted, the gear 446 can be locked by the threaded connection of the bolt 47 and the threaded hole 46 to prevent the fixed plate 1 from rotating during the cable winding process and affecting the cable winding.

[0036] Reference Figure 5 As shown, each of the two central blocks 2 has an installation hole 5 inside, and a limit strip 6 is fixedly installed around the inside of the installation hole 5.

[0037] In this embodiment, the device can be installed on the surface of the winding transmission rod through the mounting hole 5, and the two center blocks 2 can be limited by the setting of the limiting strip 6 so that the transmission rod can drive the two center blocks 2 to rotate synchronously and evenly wind the cable.

[0038] Working principle: When winding cables of different lengths, the first bearing seat 3 rotates in the forward or reverse direction through the rotational connection between the fixed disk 1 and the fixed disk 3. While the fixed disk 1 is rotating, the mounting cavity 445 inside it rotates synchronously. The mounting cavity 445 is connected to two gears 446, which drives the screw 444 to rotate synchronously. The screw 444 is connected to the threaded sleeve 442, which drives another center block 2 to move, thereby increasing or decreasing the distance between the two center blocks 2 and thus changing the length of the fixed disk 1 and the center block 2.

[0039] Furthermore, during the movement of the two center blocks 2, the several strip grooves 41 opened on the surface of the center block 2 can block the space between the two center blocks 2 through several strip rods 43, so that the cable can be evenly wound on the surface of the two center blocks 2, avoiding the appearance of height difference on the surface of the center blocks 2, which would affect the uniformity of cable winding.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
