Description

Technical Field

[0001] The utility model relates to the field of hose reels, in particular to a deceleration hose reel. Background Art

[0002] Hose reels are widely used in various workplaces, including production and assembly workshops, repair shops, car detailing shops, and 4S dealerships. They allow for free extension and retraction within a specified range and can be mounted on a wall, saving installation space. Due to their numerous advantages, they are widely used in various everyday situations. However, the return spring required to pull out the cable requires considerable force. When released, the return spring causes the cable to retract at an increasing speed, generating a significant impact force at the moment of completion, which can damage the reel or cause it to swing and injure nearby. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a deceleration hose reel that can achieve balanced forward rotation when extracting the hose, saving effort, and slow reverse rotation when retrieving the hose, preventing collisions caused by rapid retraction.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A deceleration hose reel, comprising

[0006] The housing is provided with an opening for allowing the wire tube to enter and exit;

[0007] The tube winding mechanism includes a fixed shaft connected to the inner walls of both sides of the housing, and a roller rotating around the fixed shaft, the roller is used to wind the tube, and the roller is provided with a return coil spring;

[0008] A labor-saving mechanism is provided in the drum and includes a sun gear, planetary gears, a planetary carrier, and a gear ring. The gear ring, the planetary carrier, and the sun gear are all provided with a first through hole allowing a fixed shaft to pass through. The gear ring is sleeved on the inner wall of the drum. The sun gear is rotatably connected to the fixed shaft. The planetary carrier is used to link a plurality of planetary gears and is installed between the gear ring and the sun gear.

[0009] The deceleration mechanism is arranged in the drum, and includes a connecting disk connected to the sun gear, a rotating disk installed on the connecting disk, and a deceleration ring sleeved on the inner wall of the drum and surrounding the rotating disk. The rotating disk and the deceleration ring are both provided with a second through hole allowing the sun gear to pass through. The rotating disk is provided with a circular ring surrounding the outer periphery of the connecting disk, and the inner side surface of the circular ring is provided with ratchet teeth. The outer side of the connecting disk is hinged with a pawl that engages the ratchet teeth in one direction, and the outer side of the rotating disk is hinged with a deceleration plate for contacting the inner side surface of the deceleration ring for deceleration.

[0010] The deceleration hose reel according to the present invention has at least the following beneficial effects: the housing is provided with an opening to allow the entry and exit of the wire tube. When the wire tube is withdrawn, the wire tube drives the drum to rotate forward around the fixed axis, and the planetary gears, through the gear ring, rotate around the sun gear. The planetary gears save energy and offset some of the force of the return coil spring. At this time, the pawl of the connecting disk and the ratchet teeth of the rotating disk are not engaged. When the wire tube is reversed, the return coil spring resets and drives the drum to rotate in the opposite direction, thereby retracting the wire tube into the housing. At this time, the sun gear changes its rotation direction, which drives the pawl of the connecting disk to engage with the ratchet teeth of the rotating disk, thereby driving the deceleration plate to rotate. At the same time, the deceleration plate is thrown outward under the action of centrifugal force and contacts the inner side of the deceleration ring. Due to the action of the planetary gears, the deceleration ring and the deceleration plate rotate in opposite directions, generating greater friction resistance, thereby reducing the rotation speed of the drum and the speed of wire tube recovery. Therefore, the forward rotation of the wire tube can be balanced, saving energy, and the retraction of the wire tube can be slowed down, preventing the impact caused by rapid retraction.

[0042] Reference below Figures 1-6 A deceleration hose reel is described in detail using a specific embodiment. It is worth noting that the following description is merely an illustrative illustration and does not specifically limit the utility model.

[0043] like Figures 1-6 As shown, a deceleration hose reel includes a housing 100, a hose reeling mechanism, a labor-saving mechanism and a deceleration mechanism.

[0044] Among them, the shell 100 is provided with an opening 110 that allows the wire tube 140 to enter and exit; the winding tube mechanism includes a fixed shaft 120 connected to the inner walls on both sides of the shell 100, and a roller 130 that rotates around the fixed shaft 120. The roller 130 is used to wind the wire tube 140, and the roller 130 is provided with a reset coil spring; the labor-saving mechanism is arranged in the roller 130, including a sun gear 150, a planetary gear 160, a planetary carrier 170 and a gear ring 180. The gear ring 180, the planetary carrier 170 and the sun gear 150 are all provided with a first through hole 190 that allows the fixed shaft 120 to pass through. The gear ring 180 is sleeved on the inner wall of the roller 130, the sun gear 150 is rotatably connected to the fixed shaft 120, and the planetary carrier 170 is used to link multiple planetary gears 160. Installed between the gear ring 180 and the sun gear 150; the reduction mechanism is arranged in the drum 130, including a connecting disk 200 connected to the sun gear 150, a rotating disk 210 installed on the connecting disk 200, and a reduction ring 220 sleeved on the inner wall of the drum 130 and surrounding the rotating disk 210. The rotating disk 210 and the reduction ring 220 are both provided with a second through hole 230 allowing the sun gear 150 to pass through. The rotating disk 210 is provided with a circular ring 240 surrounding the outer periphery of the connecting disk 200, and the inner side of the circular ring 240 is provided with a ratchet 250. The outer side of the connecting disk 200 is hinged with a pawl 260 that is one-way engaged with the ratchet 250, and the outer side of the rotating disk 210 is hinged with a reduction plate 270 for contacting the inner side of the reduction ring 220 to reduce speed. The housing 100 is provided with an opening 110 to allow the wire tube 140 to enter and exit. When the wire tube 140 is pulled out, the wire tube 140 drives the roller 130 to rotate forward around the fixed shaft 120, and drives the planetary gear 160 to rotate around the sun gear 150 through the gear ring 180. The planetary gear can save energy and offset part of the force of the reset coil spring. At this time, the pawl 260 of the connecting disk 200 and the ratchet 250 of the rotating disk 210 are not engaged; when reversing, the reset coil spring resets and drives the roller 130 to rotate in the opposite direction, thereby retracting the wire tube 140 Inside the housing 100, the sun gear 150 changes its rotational direction, driving the pawl 260 of the connecting disk 200 to engage with the ratchet 250 of the rotating disk 210, thereby driving the speed reducer 270 to rotate. At the same time, the speed reducer 270 is thrown outward by the centrifugal force and contacts the inner side of the speed reduction ring 220. Due to the action of the planetary gears, the speed reduction ring 220 and the speed reducer 270 rotate in opposite directions, thereby generating greater frictional resistance, thereby reducing the rotation speed of the drum 130 and the speed of the retrieving of the bobbin 140. Therefore, the bobbin 140 can be pulled out in a balanced forward rotation, saving energy, and the bobbin 140 can be retrieved in a slow reverse rotation, preventing the impact caused by rapid retrieving.

[0045] Specifically, if Figure 1-Figure 3As shown, the drum 130 is H-shaped, comprising two wide sections 280 and a long section 290 connecting the two wide sections 280. The outer sides of the long sections 290 are used to wind the wire tube 140. This H-shape configuration of the drum 130 facilitates winding the wire tube 140 and limits the position of the wire tube 140 during recovery. Furthermore, one of the wide sections 280 has a wide cavity 300, in which a return spring is located. One end of the return spring is connected to the fixed shaft 120, and the other end is connected to the inner side of the cavity 300. The long section 290 has a long cavity 310, in which the force-saving mechanism and the speed reduction mechanism are located. The wide cavity 300 on the wide section 280 facilitates the installation of the return spring, and the long cavity 310 on the long section 290 facilitates the installation of the force-saving mechanism and the speed reduction mechanism. Furthermore, a side cover 320 is provided on the side of the wide cavity 300 to cover the wide cavity 300. The side cover is provided to facilitate the installation and replacement of the reset coil spring, while limiting the return coil spring from being separated from the wide cylindrical cavity 300. The labor-saving mechanism and the speed reduction mechanism are arranged in sequence in the long cylindrical cavity 310 from top to bottom. The gear ring 180 is in the shape of a cover, which is used to cover the connection between the wide cylindrical cavity 300 and the long cylindrical cavity 310. The cover-shaped gear ring 180 is conducive to separating the wide cylindrical cavity 300 and the long cylindrical cavity 310, ensuring the installation position and stable operation of the labor-saving mechanism and the speed reduction mechanism. It should be noted that the side cover plate 320 and the gear ring 180 are also provided with a first through hole 190 that allows the fixed shaft 120 to pass through.

[0046] like Figure 4 As shown, there are three planetary gears 160, and the planetary carrier 170 has three ends. The middle portion of the planetary carrier 170 is rotatably connected to the fixed shaft 120, and the three ends of the planetary carrier 170 are respectively rotatably connected to the three planetary gears 160. The provision of three planetary gears 160 ensures stable operation and also has a good labor-saving effect.

[0047] like Figure 5 and Figure 6 As shown, the deceleration ring 220 is in the shape of a cover, and the labor-saving mechanism is provided on the top surface of the deceleration ring 220. The deceleration ring 220 is installed above the rotating disk 210 and the connecting disk 200. The cover shape of the deceleration ring 220 is conducive to covering the rotating disk 210 and the connecting disk 200 inside, ensuring stable operation. Specifically, three pawls 260 are evenly provided around the circumference of the connecting disk 200. The provision of three pawls 260 is conducive to the connection disk 200 and the rotating disk 210, ensuring that the connection disk 200 and the rotating disk 210 are not disconnected during the deceleration process. Four deceleration plates 270 are evenly provided around the circumference of the rotating disk 210. The provision of four deceleration plates 270 can increase the friction area and achieve a better deceleration effect.

[0048] It is worth mentioning that Figure 4As shown, it also includes a bottom plate 330 disposed in the drum 130, the bottom plate 330 is engaged with the inner side of the drum 130, and the gear ring 180 and the reduction ring 220 are fixedly connected to the bottom plate 330 by setting bolts. This arrangement is conducive to the disassembly and assembly of the labor-saving mechanism and the reduction mechanism.
