Description

Technical Field

[0001] This invention relates to the field of hose reel technology, specifically to a fully automatic self-cleaning hose reel. Background Technology

[0002] A hose reel is a device that can reel in and unreel hoses. When in use, the hose can be pulled out, and after use, the hose can be reeled in, reducing the footprint of the hose and making it easier to store. The hose reel can be used with a rewinding mechanism to automatically rewind the hose.

[0003] Prior art 1 (Chinese patent published on May 15, 2018, with publication number CN108033323A) is a portable endotracheal tube reel, comprising a support and a reel. The support has a handle at the top and a crossbar in the middle. The central hole of the reel is fitted into the crossbar. The middle part of the reel is a winding part, and the left and right ends are limiting parts. The limiting parts are larger than the winding part. An operation hole for the air tube to pass through is opened on the side of the limiting part. An air tube fixing part is provided on the outer side of the limiting part. After the air tube on the winding part passes through the operation hole, it is locked and fixed on the air tube fixing part. This solution has a simple structure, is easy to use, and can be carried anywhere. It facilitates the winding of the air tube, and the air tube can be easily wound and pulled out, making it safe and reliable to use. Existing technology 2 (Chinese patent publication number CN217264017U, published August 23, 2022) discloses a novel hose reel, which includes a support frame, a rotating shaft, a roller, an upper arc plate, a lower arc plate, a lateral shifting device, and a limiting device. The roller is rotatably mounted on the support frame via the rotating shaft. Both sides of the roller have side flanges, and a hose connector is provided on the arc surface of the roller. The upper and lower arc plates are installed around the roller, and their ends are fixed to the side flanges with bolts. The upper arc plate has a guide groove, into which the hose connector is embedded. This application proposes a novel hose reel that avoids vertical bending of the hose connector during winding and use, thus preventing hose breakage. Furthermore, the rotatable limiting device reduces hose wear.

[0004] Current hose reels collect hoses directly by rotating them. When the reel is long, uneven winding can easily occur. Even hose reels with automatic rewinding mechanisms require the release and application of limit switches before unwinding or rewinding the hose. This means that two people are needed to operate the hose reel, making it inconvenient to unwind or rewind the hose. Furthermore, impurities on the surface of the hose can easily be broken and wound into the reel, causing contamination. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic self-cleaning hose reel to solve the problems mentioned in the background art. In the prior art, hose reels directly collect the hose by rotation, which can easily lead to uneven winding when the reel is long. Furthermore, hose reels with automatic rewinding structures require the release and application of limit switches before reeling in and unwinding the hose, which means that two people are needed to operate them, resulting in poor convenience for reeling in and unwinding the hose.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic self-cleaning hose reel, comprising a base, a support seat, a hose reel, and a hose body. The support seat is positioned above the base, and the hose reel is disposed inside the support seat. The hose body is wound around the surface of the hose reel. A connector is provided at the front end of the hose body. Rotating shafts are fixed at both ends of the hose reel, forming a rotatable connection between the rotating shafts and the support seat. A connecting shaft is connected to the left end of the rotating shaft, and a torsion spring is disposed outside the connecting shaft to provide rotational restoring force for the connecting shaft.

[0008] The reciprocating lead screw is rotatably installed inside the connecting housing, and the reciprocating lead screw passes through the drive block and forms a threaded connection between the drive block and the connecting housing, and the drive block and the connecting housing form a left-right sliding structure;

[0009] The transmission head is fixed to the left end of the reciprocating screw and controls the rotation of the reciprocating screw;

[0010] The transmission mechanism is connected to the transmission head and controls the rotation of the transmission head.

[0011] To further optimize this technical solution, the transmission mechanism includes a transmission belt and a tension control mechanism;

[0012] A transmission belt is located on the outside of the transmission head, and the rear end of the transmission belt is connected to the connecting shaft;

[0013] The tension control mechanism is located on the outside of the transmission belt and controls the tension of the transmission belt.

[0014] To further optimize this technical solution, the tension control mechanism includes an adjusting wheel, a connecting frame, and a first return spring;

[0015] The adjusting wheel is located below the transmission belt and is in contact with the surface of the transmission belt;

[0016] A connecting frame is located on the outside of the adjusting wheel, and the adjusting wheel and the connecting frame are rotatably connected, and the connecting frame and the fixed frame are vertically sliding.

[0017] The first return spring is located below the connecting frame to provide an upward thrust to the connecting frame.

[0018] To further optimize this technical solution, the automatic cleaning mechanism includes a cleaning sleeve, a movable gear, and a fixed gear plate;

[0019] A cleaning sleeve is installed on the outside of the tube body;

[0020] The movable gear is located on the outside of the cleaning sleeve and connected to the cleaning sleeve, and the movable gear is rotatably installed inside the mounting block;

[0021] A fixed toothed plate is positioned above and between the movable gear to form a meshing connection. The fixed toothed plate passes through the mounting block and is fixedly connected to the mounting bracket.

[0022] To further optimize this technical solution, a connecting ring is fixed at the rear end of the cleaning sleeve, and a threaded connection is formed between the connecting ring and the movable gear.

[0023] To further optimize this technical solution, a movable block is fixed below the support base, and a front-to-back sliding structure is formed between the movable block and the base.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] (1) The position of the tube can be controlled by setting the mounting block. When the tube is wound and unwound by the tube drum, the mounting block can move horizontally to adjust the position of the tube, so that the tube can be wound and unwound evenly on the tube drum. It can also reduce the wear of the tube during winding and unwinding. In addition, the mounting block can move horizontally back and forth, and can be wound in multiple layers.

[0034] (2) The cleaning sleeve can clean the rolled tube, preventing contaminants from being rolled up with the tube. The cleaning sleeve can also rotate under the drive of the movable gear, improving its cleaning effect. When the installation block moves, the rotation of the movable gear can be automatically triggered by the meshing between the fixed tooth plate and the movable gear.

[0035] (3) By connecting the transmission head with the transmission belt and the connecting shaft, the reciprocating screw can be automatically driven to rotate when the tube drum rotates, and the movement control of the mounting block can be realized simultaneously. Furthermore, when the support seat moves, the adjusting wheel can push the transmission belt to move, so as to maintain the tension effect and ensure the normal transmission of power.

[0036] (4) The rotation of the tube can be limited by the connection between the limit block and the synchronous shaft, so as to keep it stable. The connection between the limit block and the synchronous shaft can be controlled by the movement of the support seat. The forward movement of the support seat can automatically release the connection between the limit block and the synchronous shaft, so that the tube can rotate. The tube can be unwound by directly pulling the tube body. It can be operated by a single person and the unwinding can be automatically carried out.

[0037] (5) By pressing the connecting groove with the fixed block, the connecting block can drive the limiting block to move, release the connection between the limiting block and the synchronous shaft, and after the tube body is released, the support seat can move backward and reset under the action of the second reset spring. The limiting block continues to limit the synchronous shaft, thereby realizing the automatic locking of the tube body. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1-10 The present invention provides the following technical solution: a fully automatic self-cleaning hose reel, comprising a base 1, a support 2, a hose reel 3 and a hose body 4. The support 2 is disposed above the base 1, and the hose reel 3 is disposed on the inner side of the support 2. The hose body 4 is wound around the surface of the hose reel 3, and a connector 8 is disposed at the front end of the hose body 4.

[0051] Example 1: The present invention provides the following technical solution, disclosing that the left and right ends of the tube roll 3 are fixed with rotating shafts 5, and the rotating shafts 5 and the support base 2 form a rotatable connection. The left end of the rotating shaft 5 is connected to a connecting shaft 6, and a torsion spring 7 is provided on the outside of the connecting shaft 6 to provide rotational reset force for the connecting shaft 6. The front end of the tube body 4 is penetrated by a mounting block 10, and a driving block 11 is fixed below the mounting block 10. A connecting shell 13 is provided on the outside of the driving block 11, and fixing brackets 15 are fixed on both the left and right ends of the connecting shell 13. The fixing brackets 15 are fixed to the base. Above 1, below the drive block 11, a reciprocating drive mechanism is provided to control the drive block 11 to move the mounting block 10 and adjust the position of the tube body 4. The mounting block 10 is equipped with an automatic cleaning mechanism to clean the surface of the tube body 4. The support seat 2 and the base 1 form a front-to-back sliding structure. The right side of the rotating shaft 5 is fixed with a synchronous shaft 26, and a limit mechanism is provided on the outside of the synchronous shaft 26 to limit the rotation of the synchronous shaft 26. A release mechanism is provided on the outside of the limit mechanism to release the limit on the synchronous shaft 26 when the support seat 2 moves forward.

[0052] When in use, the base 1 can be installed in the designated position. By pulling the tube 4, it can be controlled to unwind on the tube drum 3, causing the tube drum 3 to rotate. At the same time, the torsion spring 7 stores power. Subsequently, the rebound force of the torsion spring 7 controls the connecting shaft 6 to drive the rotating shaft 5 and the tube drum 3 to reverse, winding the tube 4. When the tube 4 is unwinding or winding, it will drive the mounting block 10 to move horizontally. The mounting block 10 can adjust the winding and unwinding position of the tube 4 so that it can match the winding position on the tube drum 3, so that it can be wound and unwound evenly, and also reduce the wear between the tube 4 and the mounting block 10.

[0053] Example 2: Based on Example 1, a reciprocating drive mechanism is disclosed, including a reciprocating screw 12, a transmission head 14, and a transmission mechanism. The reciprocating screw 12 is rotatably mounted inside the connecting housing 13, and the reciprocating screw 12 passes through the drive block 11, forming a threaded connection between the drive block 11 and the connecting housing 13. The drive block 11 and the connecting housing 13 form a left-right sliding structure. The transmission head 14 is fixed to the left end of the reciprocating screw 12 and controls its rotation. The transmission mechanism is connected to the transmission head 14 and controls its rotation. The transmission mechanism includes a transmission belt 16 and a tension control mechanism. The transmission belt 16 is located outside the transmission head 14, and its rear end is connected to the connecting shaft 6. The tension control mechanism is located outside the transmission belt 16 and controls its tension. The tension control mechanism includes an adjusting wheel 17, a connecting frame 18, and a first return spring 19. The adjusting wheel 17 is located below the transmission belt 16 and connected to the connecting shaft 6. The surfaces of the moving belt 16 are in contact with each other. The connecting frame 18 is located outside the adjusting wheel 17, and the adjusting wheel 17 and the connecting frame 18 form a rotatable connection. The connecting frame 18 and the fixed frame 15 form an up-and-down sliding structure. The first return spring 19 is located below the connecting frame 18 to provide an upward thrust for the connecting frame 18. The automatic cleaning mechanism includes a cleaning sleeve 20, a movable gear 21, and a fixed toothed plate 22. The cleaning sleeve 20 is located outside the tube body 4. The movable gear 21 is located outside the cleaning sleeve 20 and connected to the cleaning sleeve 20. The movable gear 21 is rotatably installed inside the mounting block 10. The fixed toothed plate 22 is located above the movable gear 21 and forms a meshing connection with the movable gear 21. The fixed toothed plate 22 passes through the mounting block 10 and is fixedly connected to the fixed frame 15. A connecting ring 23 is fixed to the rear end of the cleaning sleeve 20, and a threaded connection is formed between the connecting ring 23 and the movable gear 21.

[0054] When the tube drum 3 rotates, it drives the connecting shaft 6 to rotate. The connecting shaft 6 drives the transmission head 14 to rotate via the transmission belt 16. The transmission head 14 drives the reciprocating screw 12 to rotate. The reciprocating screw 12 drives the drive block 11 to move through the threaded connection between the drive block 11 and the drive block 11. This causes the drive block 11 to drive the mounting block 10 to move horizontally, adjusting the position of the tube body 4. At the same time, when the mounting block 10 moves, it drives the movable gear 21 to move below the fixed tooth plate 22. The movable gear 21 rotates, driving the cleaning sleeve 20 to rotate, improving the cleaning effect of the cleaning sleeve 20. The cleaning sleeve 20 can also be removed from the movable gear 21 by rotating it for replacement. When the support seat 2 moves, the tension of the transmission belt 16 changes. At this time, the first return spring 19 can push the connecting frame 18 to drive the adjusting wheel 17 to move, causing the adjusting wheel 17 to squeeze the transmission belt 16 to maintain tension, so that the power between the connecting shaft 6 and the transmission head 14 can be transmitted stably.

[0055] Example 3: Based on Example 1, a movable block 24 is fixed below the support base 2. The movable block 24 and the base 1 form a front-to-back sliding structure. A second return spring 25 is provided on the front side of the movable block 24 to provide a rearward thrust to the movable block 24. The limiting mechanism includes a limiting block 27 and a third return spring 29. The limiting block 27 is located below the synchronous shaft 26, and the limiting block 27 and the support base 2 form a vertical sliding structure. The third return spring 29 is located on the limiting block 27. The lower part of 7 provides upward thrust to the limiting block 27. The upper part of the limiting block 27 has an arc-shaped structure design, and the upper surface of the limiting block 27 is made of rubber. The release mechanism includes a connecting block 28, a connecting groove 30, and a fixing block 31. The connecting block 28 is fixed below the limiting block 27. The connecting groove 30 is opened below the connecting block 28. The fixing block 31 is located in front of the connecting groove 30, and the front end of the fixing block 31 is fixedly connected to the fixing frame 15. The rear side of the fixing block 31 has an inclined structure design.

[0056] A push seat 9 is provided on the rear side of the support base 2 to assist in pushing the support base 2 forward. After pushing the support base 2 forward, the winding drum 3 can rotate to automatically wind the tube body 4. When unwinding the tube body 4, the tube body 4 can be pulled directly. At this time, the synchronous shaft 26 is limited and the tube body 4 cannot be unwound. The support base 2 will slide forward under force, causing the fixing block 31 to press the connecting groove 30, which will drive the connecting block 28 and the limiting block 27 to move, releasing the limiting effect of the limiting block 27 on the synchronous shaft 26, allowing the winding drum 3 to rotate and unwind the tube body 4. After stopping pulling the tube body 4, the second return spring 25 pushes the movable block 24 to move the support base 2 to reset it, releasing the pressing of the fixing block 31 on the connecting groove 30. Under the action of the third return spring 29, the limiting block 27 continues to limit the synchronous shaft 26, causing the winding drum 3 to stop rotating and keeping the unwinding of the tube body 4 stable.
