Description

Technical Field

[0001] This utility model relates to the field of winding and recycling devices, and in particular to a winding and recycling device for a fuel dispenser hose. Background Technology

[0002] Gas stations are places specifically designed to provide fuel for vehicles such as cars and motorcycles. Fuel dispensers are devices in gas stations used to deliver fuel to vehicles or other containers. Fuel dispensers use components such as fuel pumps, fuel lines, and nozzles to deliver fuel from the gas station's storage tanks to the vehicle's fuel tank. The fuel dispenser hose is the connecting pipe between the gas station's fuel pump and the vehicle's fuel tank; it is used to transfer fuel from the fuel pump's nozzles to the vehicle's fuel tank.

[0003] Because the hose needs to extend and retract during refueling, without a rewinding mechanism, the hose may scatter in the refueling area, taking up space and potentially being run over by vehicles. Furthermore, the hose, being exposed to the ground for a long time, will be affected by physical wear, ultraviolet radiation, and corrosion from pollutants, thus reducing its service life.

[0004] Therefore, those skilled in the art have provided a rewinding and recycling device for fuel dispenser hoses to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a rewinding and recycling device for a fuel dispenser hose. A first spring drives the thorn to approach the ratchet, thus maintaining unidirectional rotation when unfolding the hose, preventing the drum from driving the hose in reverse and ensuring smooth use. A torsion spring drives the drum to rotate in the opposite direction to rewind the hose. Friction plates prevent the rotation speed from being too fast. A second spring drives the guide wheel to always be in contact with the hose, providing better guidance for the unfolding and rewinding of the hose.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fuel dispenser hose rewinding and recycling device includes a housing, a drum rotatably connected inside the housing, a one-way rotation structure inside the housing, and a rotary guide structure on the housing. The unidirectional rotation structure includes two rotating shafts, which are fixedly connected to the center of the front and rear ends of the drum. A ratchet is rotatably connected to the center of the rear end of the housing. A thorn is rotatably connected to one side of the rear end of the housing. A fixing plate is fixedly connected to one side of the rear end of the housing. A No. 1 spring is fixedly connected to the upper end of the fixing plate. The upper end of the No. 1 spring is fixedly connected to the thorn. A rotating disk is fixedly connected to the rear end of the thorn. The above technical solution allows for easy winding of the hose to be stored around the outside of the drum wall, preventing the hose from scattering. The ratchet and thorn configuration ensure that the hose extends in one direction during use. Unidirectional rotation prevents the hose from reversing during winding, ensuring smooth extension. The first spring facilitates the return of the thorn to its original position after the ratchet rotates and squeezes it, ensuring stable unidirectional rotation.

[0007] Furthermore, the rotary guide structure includes two torsion springs, which are sleeved on the outer wall of the rotating shaft. One side of the torsion spring is fixed inside the housing. Support plates are fixedly connected to the front and rear ends of the upper end of one side of the housing. Connecting plates are fixedly connected to both sides of the support plates. A movable seat is slidably connected between the two connecting plates. A guide wheel is rotatably connected inside the movable seat. The above technical solution utilizes a torsion spring to facilitate the reverse rotation of the drum after it rotates, thereby completing the winding of the hose. The rubber head on the outer connecting plate near the housing facilitates the insertion of the hose between the two movable seats. The guide wheel provides guidance during hose unwinding or winding, preventing the hose from tangling or folding.

[0008] Furthermore, a connecting shaft is fixedly connected to the rear end of the rotating shaft on one side, and the rear end of the connecting shaft is fixedly connected to a ratchet. The above technical solution allows the connecting shaft to facilitate the rotation of the ratchet after the drum rotates.

[0009] Furthermore, a rotating block is fixedly connected to one side of the tip of the thorn, and the rotating block rotates inside the housing; The above technical solution allows the thorn to rotate at the rear of the device by setting the rotating block, thus maintaining the unidirectional rotation of the drum.

[0010] Furthermore, a snap-fit ​​block is fixedly connected to one side of the upper end of the thorn, and a rotating snap-fit ​​seat is rotatably connected to one side of the rear end of the housing; The above technical solution facilitates the rotation and fixation of the thorns by setting up the snap-fit ​​block and rotating snap-fit ​​seat, thereby making it easier for the roll to reverse during winding.

[0011] Furthermore, friction plates are fixedly connected to the inside of the rotating shaft on the side away from the drum and at both the front and rear ends inside the housing, and the two friction plates are in contact with each other; The above technical solution, through the setting of friction plates, facilitates the stabilization of the rotation speed of the rotating shaft during rewinding, avoiding rewinding that is too fast or too slow.

[0012] Furthermore, a second spring is fixedly connected to one side of the support plate near the center of the housing, and one side of the second spring is fixedly connected to the movable seat; The above technical solution utilizes the second spring to provide elastic force, ensuring that the movable seat drives the guide wheel to always be in contact with the hose.

[0013] Furthermore, T-shaped sliders are fixedly connected to both sides of the movable seat, and a T-shaped groove is provided inside the connecting plate on the side near the movable seat; The above technical solution allows the T-shaped slider to slide between the two connecting plates when subjected to vibration.

[0014] This utility model has the following beneficial effects: 1. The present invention proposes a rewinding and recycling device for a fuel dispenser hose. The ratchet and thorn settings facilitate the unidirectional rotation of the drum. When the hose is unwound, the drum and ratchet rotate together. When the ratchet rotates, it drives the thorn to rotate. Then, the first spring drives the thorn back to its original position. The drum always maintains unidirectional rotation when the hose is unwound, thereby ensuring the safe and smooth use of the hose.

[0015] 2. The present invention proposes a rewinding and recycling device for a fuel dispenser hose. The torsion spring facilitates automatic hose rewinding. When the hose is unwound, the torsion spring deforms, and after the thorns are propelled, the torsion spring drives the drum to rotate in the opposite direction, so that the hose is wound on the drum. At the same time, the guide wheel always keeps in contact with the outer wall of the hose, playing a guiding role when the hose is unwound and rewound, thus achieving better rewinding and recycling.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figure 1-3 This utility model provides a specific implementation method: A refueling machine hose winding and recycling device includes a housing 1, a drum 2 rotatably connected inside the housing 1, a one-way rotation structure 3 inside the housing 1, and a rotary guide structure 4 on the housing 1. The unidirectional rotation structure 3 includes two rotating shafts 301, which are fixedly connected to the center of the front and rear ends of the drum 2. The drum 2 facilitates winding the hose to be stored around the outside of the drum wall, preventing the hose from scattering. A ratchet 303 is rotatably connected to the center of the rear end of the housing 1. A connecting shaft 302 is fixedly connected to the rear end of one rotating shaft 301, and the rear end of the connecting shaft 302 is fixedly connected to the ratchet 303. The connecting shaft 302 facilitates the rotation of the ratchet 303 after the drum 2 rotates. A thorn 304 is rotatably connected to one side of the rear end of the housing 1. The ratchet 303 and thorn 304 ensure that the hose extends in one direction during use. Unidirectional rotation prevents the hose from reversing during winding, ensuring smooth extension of the hose. A rotating block 307 is fixedly connected to one side of the front end of the thorn 304. 7. Rotates inside the housing 1. The rotating block 307 facilitates the rotation of the thorn 304 at the rear of the device, maintaining the unidirectional rotation of the drum 2. A fixing plate 305 is fixedly connected to one side of the rear end of the housing 1. A first spring 306 is fixedly connected to the upper end of the fixing plate 305. The upper end of the first spring 306 is fixedly connected to the thorn 304. The first spring 306 facilitates the thorn 304 to return to its original position after the ratchet 303 rotates and squeezes the thorn 304, so that the unidirectional rotation can be carried out stably. A rotating disk 310 is fixedly connected to the rear end of the thorn 304. A snap-fit ​​block 308 is fixedly connected to one side of the upper end of the thorn 304. A rotating snap-fit ​​seat 309 is rotatably connected to one side of the rear end of the housing 1. The snap-fit ​​block 308 and the rotating snap-fit ​​seat 309 facilitate the rotation and fixation of the thorn 304, thereby facilitating the reversal of the drum 2 during winding.

[0020] Reference Figure 1 , Figure 4 and Figure 5The rotary guide structure 4 includes two torsion springs 401. The torsion springs 401 are sleeved on the outer wall of the rotating shaft 301. One side of the torsion spring 401 is fixed inside the housing 1. The torsion springs 401 facilitate the reverse rotation of the drum 2 after it rotates, thus completing the winding of the hose. Friction plates 402 are fixedly connected to the front and rear ends of the rotating shaft 301 on the side away from the drum 2 and inside the housing 1. The two friction plates 402 are in contact with each other. The friction plates 402 help stabilize the rotation speed of the rotating shaft 301 during winding, preventing excessively fast or slow winding. Support plates 403 are fixedly connected to the front and rear ends of the upper end of one side of the housing 1. Connecting plates 406 are fixedly connected to both sides of the support plates 403. The rubber head of the outer connecting plate 406 near the housing 1 facilitates the insertion of the hose between the two movable seats 404. A movable seat 404 is slidably connected between the connecting plates 406. A second spring 409 is fixedly connected to the side of the support plate 403 near the center of the housing 1. One side of the second spring 409 is fixedly connected to the movable seat 404. The second spring 409 provides elastic force so that the movable seat 404 drives the guide wheel 405 to always be in contact with the hose. The guide wheel 405 is rotatably connected inside the movable seat 404. The guide wheel 405 provides guidance when the hose is unfolded or rewound, preventing the hose from tangling or folding. T-shaped sliders 407 are fixedly connected to both sides of the movable seat 404. A T-shaped groove 408 is opened inside the connecting plate 406 near the movable seat 404. The T-shaped slider 407 facilitates the sliding of the movable seat 404 between the two connecting plates 406 when subjected to vibration.

[0021] Working principle: In use, when the hose needs to be pulled out, the hose drives the drum 2 and the two rotating shafts 301 to rotate. Under the action of the connecting shaft 302, the ratchet 303 also rotates. When the ratchet 303 rotates, it squeezes the thorn 304, causing it to rotate. At the same time, the first spring 306 is stretched. Then, the spring drives the thorn 304 back to its original position, restricting the rotation direction of the ratchet 303 to rotate in one direction. Thus, the drum 2 can only rotate in one direction, ensuring that the drum 2 flips when the hose is extended, and making the extension of the hose smoother. When it is necessary to retract the hose into the device, the thorn 304 is pushed upwards, causing the locking block 308 to approach and engage. Inside the movable locking seat 309, due to the small inner diameter of the lower side of the locking seat and the fact that the locking block 308 is made of elastic rubber, the block will not easily slip out, thus relieving the restriction effect of the thorn 304 on the ratchet 303. Under the action of the torsion spring 401, the drum 2 rotates in the opposite direction, causing the hose to wind around the outside of the drum wall, thereby completing the winding of the hose and preventing the hose from scattering on the outside. During the rotation, the two friction plates 402 contact each other, which can effectively prevent the rotation speed from being too fast. During the extension or winding of the hose, under the action of the second spring 409, the guide wheels 405 on the front and rear sides are always in contact with the outer wall of the hose, so that they can better play a guiding role and prevent the hose from tangling or folding.
