Description

Technical Field

[0001] The present invention relates to a hose reel, and in particular to a non-powered automatic hose reel. Background Art

[0002] A hose reel, also known as a cable winder, reel, or drum, winds a pipeline onto a drum. The reel provides power, water, and ventilation to the pipeline, allowing it to be pulled out when in use and reeled back in when not in use. These reels are widely used in various industrial and commercial settings, including production and assembly workshops, maintenance shops, mining operations, and vehicle cleaning facilities.

[0003] Existing automatic hose reels primarily use a coil spring or similar elastic member to retract the pipe. The pipe is wound around a reel equipped with a coil spring. When the pipe is pulled out, the pipe drives the reel to rotate, which stretches the coil spring, causing it to deform. When the pipe needs to be recovered, the elastic force of the coil spring drives the reel back, allowing the pipe to be rewound and recovered. This type of hose reel requires a significant pulling force to overcome the elastic force of the coil spring during the pipe pulling process. Furthermore, the more pipe is pulled out, the more the reel rotates, which in turn increases the elastic force of the coil spring. This results in a greater pulling force required to pull the pipe outward, which is very labor-intensive. Furthermore, the longer the pipe, the greater the force generated during rewinding. If the hose reel is not secured, it will cause the reel to bounce erratically during rewinding, causing the pipe to swing erratically, which is very dangerous for both the equipment and personnel. Therefore, in actual use, industrial and mining enterprises will fix this automatic hose reel on the wall or the ground, and workers will control the rewinding direction when rewinding. However, this greatly limits the scope of use of the automatic hose reel, especially in industrial and mining enterprises that occupy a large area, and also consumes extra manpower.

[0004] To address this issue, existing technologies have introduced automatic hose reels that utilize hydraulic power to rewind. However, these reels require only water, and drainage during rewinding is a problem. Consequently, their application scenarios are limited and they are not popular. Other automatic hose reels utilize electrical power to rewind, which offers smooth rewinding. However, these reels are expensive and require electricity, making them difficult to use. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides an automatic hose reel that utilizes the principle of like-pole repulsion to rewind the storage drum. Compared to existing energy storage-type automatic hose reels, the present invention does not require additional energy storage equipment, so that no additional resistance needs to be overcome when the pipeline is stretched. At the same time, the storage drum rotates smoothly and at a relatively uniform speed during rewinding due to magnetic force, thus avoiding the problem of the energy storage-type automatic hose reel being unable to release force stably during rewinding, causing the shell and pipeline to jump. Compared to existing energy storage-type automatic hose reels that must be fixed for use and consume more energy during stretching, the automatic hose reel of the present invention can be moved at will, and will remain stable during use. At the same time, stretching is labor-saving, and rewinding is smooth and fast. The hose reel of the present invention has a wider range of usage scenarios and is more cost-effective.

[0006] In order to solve the above technical problems, the present invention solves the problem through the following technical solutions: an automatic hose reel, including a storage drum, a pipeline wound on the storage drum, a wheel disc provided on one side of the storage drum, a driving disk connected to the wheel disc for transmission, a plurality of driving magnets evenly arranged along the circumferential direction of the driving disk, the driving magnet is tilted on the driving disk, and a driving handle is rotatably provided, and a main magnet of the same polarity that repels the driving magnet is provided on the driving handle. After the driving handle is rotated, the main magnet can face or separate from the driving magnet.

[0007] Preferably, in the above technical solution, the wheel disc is provided with an inner gear ring, the drive disc is provided with an outer gear ring, and the outer gear ring is meshed with the inner gear ring.

[0008] Preferably, in the above technical solution, the ratio of the number of teeth of the inner gear ring to the outer gear ring is 8-16:1.

[0009] Preferably, the above technical solution further includes a shell, a support column is provided in the shell, the storage tube is rotatably provided on the support column, the drive disk is fixedly provided in the shell, and the drive handle is rotatably provided in the shell.

[0010] Preferably, in the above technical solution, a switch connected to the driving handle is provided on the housing, and the switch controls the rotation of the driving handle.

[0011] Preferably, the wheel is provided with an outer ring ratchet, and a limit member cooperating with the outer ring ratchet is rotatably provided in the shell, and the limit member is transmission-connected with the driving handle. When the driving handle rotates so that the main magnet faces the driving magnet, the limit member disengages from the outer ring ratchet. When the driving handle rotates so that the main magnet disengages from the driving magnet, the limit member engages with the outer ring ratchet to prevent the wheel from rotating in the pipeline winding direction.

[0012] Preferably in the above technical solution, a slide groove is provided on the limiting member, a transmission rod matching the slide groove is provided on the driving handle, and the limiting member is also connected to one end of a spring, and the other end of the spring is fixed in the shell.

[0013] Preferably, in the above technical solution, a limiting slide is provided on the driving disk, the limiting slide comprises a release groove and a fixing groove which are interconnected, and the switch is provided with a slider which can slide in the limiting slide.

[0014] Preferably, in the above technical solution, a control slot is provided on the driving handle, and a control rod is provided on the switch for extending into the control slot and controlling the rotation of the driving handle.

[0015] Preferably in the above technical solution, the shell includes a fixed surface and a movable surface, and a movable wheel is further provided on the shell, the bottom of the movable wheel is higher than the fixed surface, and the bottom of the movable wheel is lower than the movable surface.

[0016] Preferably in the above technical solution, a pull rod is rotatably provided on the shell.

[0017] Preferably, in the above technical solution, the angle between the driving magnet and the horizontal center line of the driving disk is between 25° and 75°.

[0018] Preferably, in the above technical solution, the angle between the driving magnet and the horizontal line of the center of the driving disk is 30°, 45° or 60°.

[0019] As is known, existing non-powered automatic hose reels primarily utilize elastic elements, such as coil springs, as energy storage devices. However, a major drawback of these energy storage devices is that the longer the hose is stretched, the more force is required. Furthermore, to maintain the rewinding force, the length of the hose is proportional to the energy storage capacity of the elastic element. Therefore, to accommodate the average person's strength and the size of the hose reel, the length of the hose within these automatic hose reels is kept within a specific range. This imposes certain limitations on practical operation. Another major drawback is that the elastic element is unlikely to release the stored force evenly during rewinding, causing vibrations in the housing and preventing the hose from rewinding smoothly. This forces these products to be used in a fixed position to avoid vibration and requires the installation of expensive dampers to ensure smooth rewinding. Crucially, the fixed length and fixed nature of the hose are fatal flaws for large and extra-large industrial and mining sites, hindering the widespread adoption of non-powered automatic hose reels.

[0020] To address the above problems, the present invention improves the rewinding mechanism. It uses magnetic force as the rewinding energy source, eliminating the energy storage device. The principle is that a drive disc engages with a wheel on the storage drum. The drive disc is provided with a ring-shaped array of magnets, with the magnets forming a predetermined angle with the horizontal centerline of the drive disc. A rotatable drive handle is provided on the outside of the drive disc. The drive handle is provided with a main magnet that repels the magnets on the drive disc, with the two opposing faces of the main magnet and the magnets on the drive disc having the same magnetic poles. Rotating the drive handle so that the main magnet faces the array of magnets on the drive disc causes the drive disc to rotate due to the repulsion of the same magnets. Because the magnets on the drive disc are evenly arranged, as long as the main magnet is aligned with the drive disc, the drive disc rotates at a constant speed relative to the magnets, thereby driving the storage drum. This arrangement ensures smooth retraction of the pipeline during rewinding, eliminating the problem of line jumps caused by uneven force and speed. The rewinding speed is positively correlated with the repulsive force between the main magnet and the magnets on the drive disc, making it easy to adjust. Since no energy storage device is required, no additional energy needs to be expended during the stretching process of the pipeline, making the stretching of the pipeline easy and quick. Similarly, the length of the pipeline has no restrictions on stretching and rewinding, and can be determined according to actual needs. Compared with the existing non-powered automatic hose reels, the pipeline can be greatly increased. When both stretching and rewinding are stable, the product of the present invention does not need to be fixed for use. It can be operated by simply placing it in the corresponding position according to actual needs. The hose reel will not be displaced during either the stretching or rewinding process, and can remain stable at all times, greatly enriching the usage scenarios. In addition, the product of the present invention can achieve the same functions as an electric hose reel, but compared with the electric hose reel, this product does not require electricity and is low in cost.

[0021] Compared with the existing non-powered automatic hose reel, the product of the present invention has the characteristics of simple structure. Unlike the coil spring type hose reel where the coil spring is arranged in the storage tube, the transmission mechanism driving handle and driving disk of the present application are both arranged in the storage tube, which can be easily repaired once damaged. The demagnetization speed and probability of the magnet are much lower than the probability of damage to the coil spring. At the same time, the cost of the magnet is much lower than that of the coil spring.

[0022] The automatic hose reel of the present invention can be moved freely and remains stable during use. It is labor-saving to stretch and rewind smoothly and quickly. It has a wide range of applications and is low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example 1: Figures 1 to 12 As shown, an automatic hose reel includes a shell 1 and a storage tube 2. A support column 15 is provided in the shell 1. The storage tube 2 can be rotatably set on the support column 15. A pipeline 9 is wound on the storage tube 2. A blocking ring 91 is provided at the head of the pipeline 9. The blocking ring 91 is always outside the opening 14.

[0036] A wheel disc 21 is provided on one side of the storage tube 2. An inner gear ring 22 is provided on the wheel disc 21. An outer ring ratchet 23 is also provided outside the inner gear ring 22. The wheel disc 21 is transmission-connected to a drive disc 3. The drive disc 3 includes a drive disc housing 31. The drive disc housing 31 is fixed in the housing 1 through a drive disc sleeve 37 and a drive disc fixing seat 16 on the housing 1. A power disc 34 is provided in the drive disc housing 31. A plurality of drive magnets 35 are evenly arranged on the power disc 34 along the circumferential direction. The drive magnets 35 are tilted on the power disc 34. The angle between the drive magnets 35 and the horizontal center line of the power disc 34 is between 25° and 75°, preferably 30°, 45° or 60°. An outer gear ring 36 is provided on the back of the power disc 34, and the outer gear ring 36 is engaged with the inner gear ring 22. The gear ratio of the inner gear 22 to the outer gear ring 36 is between 8-16:1, preferably 13:1 or 11:1.

[0037] A driving handle 4 is rotatably mounted within the housing 1. A driving handle sleeve 42 is mounted on the driving handle 4. A driving handle rotating seat 17 is mounted within the housing 1. The driving handle 4 rotates about the driving handle rotating seat 17. A main magnet 41 of the same polarity as the driving magnet 35 is mounted on the driving handle 4 and repels the main magnet 41. Rotation of the driving handle 4 allows the main magnet 41 to face or separate from the driving magnet 35. When the main magnet 41 faces the driving magnet 35, the main magnet 41 is parallel to the moving magnet 35.

[0038] The housing 1 is provided with a switch 5 connected to the drive handle 4. The switch 5 includes a reversing plate 51 and a control rod 54. The drive handle 4 is provided with a control slot 43. The control rod 54 extends into the control slot 43 and is movable within the control slot 43. The drive disc 3 also includes an extension plate 32. The extension plate 32 is provided with a limit slide 33. The limit slide 33 includes a release slot and a fixed slot that are interconnected. The release slot includes a left release slot 331 and a right release slot 332. The fixed slot includes a top fixed slot 333 and a bottom fixed slot 334. The reversing plate 51 is provided with a slider that can slide within the limit slide 33.

[0039] A stopper 6 is also rotatably mounted within the housing 1, engaging with the outer ratchet teeth 23. A stopper sleeve 61 is mounted on the stopper 6, and a stopper rotating seat 18 is disposed within the housing 1. The stopper 6 rotates about the stopper rotating seat 18. A slot 62 is provided on the stopper 6, and a transmission rod 44 is provided on the drive handle 4 to engage with the slot 62. The stopper 6 is also connected to one end of a spring 63, the other end of which is fixed to a spring post 19 within the housing 1. When the drive handle 4 rotates so that the main magnet 41 faces the drive magnet 35, the stopper 6 disengages from the outer ratchet teeth 23. When the drive handle 4 rotates so that the main magnet 41 disengages from the drive magnet 35, the stopper 6 engages with the outer ratchet teeth 23, preventing the wheel from rotating in the pipeline reeling direction.

[0040] The housing 1 includes a fixed surface 11 and a movable surface 12. The housing 1 is also provided with a movable wheel 8, the bottom of which is higher than the fixed surface 11 and lower than the movable surface 12. A pull rod 7 is also rotatably mounted on the housing, and a pull switch 71 is also provided on the housing 1 to control the rotation of the pull rod 7. The housing 1 also has a receiving slot 13 for storing debris, and a removable cover 131 is provided on the receiving slot 13.

[0041] In the initial state, the stopper 6 engages the outer ratchet 23 under the action of the spring 63. The main magnet 41 on the drive handle 4 disengages the drive magnet 35, disengaging the drive disc 3 from operation. Simultaneously, the slider of the switch 5 abuts against the top fixed slot 333. The operator can rotate the pull rod 7 using the pull rod switch 71. Pulling the pull rod 7 to position the movable surface 12 toward the ground allows the product of the present invention to be freely moved using the movable wheels 8. Once in the working position, the fixed surface 11 faces the ground, freeing the movable wheels 8 from the ground and maintaining the product of the present invention's stability. The pipeline 9 can now be pulled out at any time. Because the outer ratchet 23 is directional, it does not hinder the extension of the pipeline 9 during the process, and its resistance is negligible. This makes pulling easy and convenient. When reversing is required, simply turn the product of the present invention. After extension, the outer ratchet 23 prevents the storage drum 2 from rotating even under external force. To rewind, simply press the switch 5. When the switch 5 is pressed, the slider moves from the top fixing slot 333 through the left or right release slot 331, 332, and into the bottom fixing slot 334, where it is secured. Because the bottom fixing slot 334 is lower than the top fixing slot 333, the displacement of the switch 5 during this process is transmitted to the drive handle 4 via the control rod 54, thereby driving the drive handle 4 to rotate. The gap between the control rod 54 and the control slot 43 offsets the displacement from the bottom of the left or right release slot 331, 332, to the bottom fixing slot 334. As the drive handle 4 rotates, the stopper 6 disengages the outer ratchet teeth 23. At this point, the spring 63 stretches, generating an elastic force. However, because the switch 5 is pressed against the stopper 6, it still cannot engage the outer ratchet teeth 23. Simultaneously, the main magnet 41 on the drive handle 4 moves above the drive disk 3. At this point, the main magnet 41 should be parallel to, and projectedly overlap, any one of the drive magnets 35. Because the main magnet 41 and the driving magnet 35 repel each other due to their similar polarity, when the main magnet 41 is fixed, the driving magnet 35 will move away from the main magnet 41. Since the driving magnets 35 are arranged uniformly on the power disk 34, as the previous driving magnet 35 moves away, the next driving magnet 35 approaches. Under the action of inertia and magnetic force, the power disk 34 moves at a relatively uniform speed in this state, thereby causing the storage tube 2 to rewind. As long as the main magnet 41 does not move, the storage tube 2 will rotate at a varying relative uniform speed until the blocking ring 91 is stuck in the opening 14. At this point, even if there is a repulsive force between the main magnet 41 and the driving magnet 35 under the action of the blocking ring 91, the reaction force is stronger, causing the power disk 34 to stop. After the pipeline 9 is rewound, the switch 5 is pressed again. The slider moves from the bottom fixing slot 334 through the left release slot 331 or the right release slot 332 into the top fixing slot 333 and is fixed. Under the action of the spring 63, the stopper 6 engages the outer ring ratchet 23, and the main magnet 41 disengages the driving magnet 35, allowing the pipeline to be easily extended. If switch 5 is not pressed, the pipeline needs to overcome the magnetic force. The staff can clearly feel this force and then press the switch.

[0042] Example 2: Compared with Example 1, in this example, there is no need for a pull rod and moving wheels, and the vehicle can be directly dragged and moved.

[0043] Example 3: Compared with Example 1, in this example, there is no need for a pull rod and moving wheels, and the device can be fixed before use.

[0044] Example 4: Compared with Example 1, in this example, no limit piece and outer ring ratchet are required, and the rotation of the driving handle is controlled only by a switch.

[0045] Example 5: Compared with Example 1, in this embodiment, there is no need for a limiter, an outer ring ratchet, a shell, a pull rod attached to the shell, and a moving wheel. The storage cylinder can be rotated by an additional shelf that supports the rotation of the storage cylinder. The driving handle and the driving disk are set on the shelf, and the driving handle and the driving disk are manually rotated to cooperate to generate a repulsive force.
