Description

Technical Field

[0001] This utility model belongs to the technical field of fuel refueling equipment, and relates to a special refueling gun for motorcycles. Background Technology

[0002] Motorcycles are lightweight vehicles with a two-wheeled or, in rare cases, three-wheeled structure, powered by fuel or electricity. Due to their high flexibility, high traffic efficiency, and low operating costs, they are widely used in urban commuting, long-distance travel, competitive sports, and special operations.

[0003] Motorcycle refueling is a crucial part of routine maintenance. However, due to the small capacity of the fuel tank and the special position of the fuel tank opening, it is difficult to insert the traditional refueling nozzle securely into the fuel tank opening. Refueling operators usually have to hold the refueling nozzle in the air to operate it. This posture requires the muscles of the hands, shoulders and neck to exert continuous force to maintain stability. Long-term operation can easily lead to problems such as muscle strain, nerve compression and decreased work efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is that refueling motorcycles is a key part of daily maintenance. However, due to the small capacity of the fuel tank and the special position of the fuel tank opening, it is difficult for traditional refueling nozzles to be inserted stably into the fuel tank opening. Refueling operators usually need to hold the refueling nozzle in the air to operate it. This posture requires the muscles of the hands, shoulders and neck to exert continuous force to maintain stability. Long-term operation can easily lead to problems such as muscle strain, nerve compression and decreased work efficiency.

[0005] The present invention relates to a motorcycle-specific fuel nozzle, comprising a motorcycle-specific fuel nozzle body, a fuel nozzle trigger installed in the middle of the motorcycle-specific fuel nozzle body, an oil outlet pipe connected to one end of the motorcycle-specific fuel nozzle body, a fuel nozzle gear hook installed in the middle of the motorcycle-specific fuel nozzle body, and a locking component provided at the end of the oil outlet pipe away from the motorcycle-specific fuel nozzle body to facilitate positioning of the motorcycle-specific fuel nozzle body.

[0006] The positioning assembly includes a cylindrical pipe positioning block, a conical pipe positioning block, and multiple sets of positioning slots. The cylindrical pipe positioning block is installed at the end of the oil outlet pipe away from the main body of the motorcycle-specific fuel nozzle. The conical pipe positioning block is fixed to the end face of the cylindrical pipe positioning block near the main body of the motorcycle-specific fuel nozzle. The multiple positioning slots are respectively opened around the middle of the cylindrical pipe positioning block and the conical pipe positioning block.

[0007] Both the cylindrical and conical pipe positioning blocks are made of transparent thermoplastic polyurethane, and the large end diameter of the conical pipe positioning block is designed to be 55mm.

[0008] The oil outlet pipe has a self-sealing return air hole at one end near the cylindrical pipe positioning block, and a vent pipe that can be triggered to self-seale is connected to the inner end of the self-sealing return air hole.

[0009] Multiple sets of ventilation slots are provided around the center of the oil outlet pipe near the conical pipe positioning block.

[0010] An extended transparent gas collection hood is connected to the middle of the oil outlet pipe via a retaining spring.

[0011] The extended transparent gas collection hood is made of elastic and transparent polyurethane material.

[0012] The inner diameter of the extended transparent gas collection hood near the fuel tank is 70mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting the positioning component, the motorcycle-specific fuel nozzle body can be positioned when refueling the motorcycle, so that the motorcycle-specific fuel nozzle body can stand at the fuel tank, thereby reducing the difficulty of the traditional fuel nozzle being firmly inserted into the motorcycle fuel tank opening and the need for the refueling operator to hold the fuel nozzle in the air to operate it. As a result, the continuous exertion of the hand, shoulder and neck muscles can easily cause muscle strain, nerve compression and decreased work efficiency of the staff.

[0014] By pressing the sealing surface of the extended transparent vent cover tightly against the fuel tank opening when refueling a motorcycle, the fuel level at the tank opening can be observed. The elasticity of the extended transparent vent cover material also helps to press against the outer surface of the fuel tank opening, reducing fuel splashing and collecting the fuel vapors displaced during refueling, thus avoiding safety, health, and environmental problems caused by the escape of fuel vapors.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1 like Figures 1-4 As shown, a motorcycle-specific fuel nozzle includes a motorcycle-specific fuel nozzle body 1, a fuel nozzle trigger 11 installed in the middle of the motorcycle-specific fuel nozzle body 1, an oil outlet pipe 12 connected to one end of the motorcycle-specific fuel nozzle body 1, a fuel nozzle gear hook 13 installed in the middle of the motorcycle-specific fuel nozzle body 1, and a locking component provided at the end of the oil outlet pipe 12 away from the motorcycle-specific fuel nozzle body 1 to facilitate positioning the motorcycle-specific fuel nozzle body 1.

[0027] The positioning assembly includes a cylindrical pipe positioning block 2, a conical pipe positioning block 21, and multiple positioning slots 22. The cylindrical pipe positioning block 2 is installed at the end of the oil outlet pipe 12 away from the motorcycle-specific fuel nozzle body 1. The conical pipe positioning block 21 is fixed to the end face of the cylindrical pipe positioning block 2 near the motorcycle-specific fuel nozzle body 1. Multiple positioning slots 22 are respectively opened around the middle of the cylindrical pipe positioning block 2 and the conical pipe positioning block 21.

[0028] Both the cylindrical pipe positioning block 2 and the conical pipe positioning block 21 are made of transparent thermoplastic polyurethane, and the large end diameter of the conical pipe positioning block 21 is designed to be 55mm.

[0029] The oil outlet pipe 12 has a self-sealing return air hole 4 at one end near the cylindrical pipe positioning block 2, and a vent pipe that can be self-sealed is connected to the inner end of the self-sealing return air hole 4.

[0030] During operation, the outer diameter of the cylindrical pipe positioning block 2 matches the inner diameter of the fuel tank opening, leaving a 2mm gap for easy insertion and refueling. The inner hole of the cylindrical pipe positioning block 2 and the outer diameter of the oil outlet pipe 12 are seamlessly fitted, and the positioning slot 22 can be used for axial positioning of the motorcycle-specific refueling gun body 1. The oil outlet pipe 12 is inserted into the fuel tank to a minimum depth of 30mm. The outer diameter of the cylindrical pipe positioning block 2 and the conical pipe positioning block 21 is designed to be 30mm, which facilitates guidance and provides positioning length. For refueling gun positioning in motorcycle fuel tanks without crossbars, the positioning slot 22 at the upper end of the cylindrical pipe positioning block 2 and the conical pipe positioning block 21 is designed with a large end diameter of 55mm. The self-sealing air return hole of the nozzle is moved 10mm towards the nozzle head than that of ordinary refueling guns, ensuring timely self-sealing when full, while maintaining a longer positioning section length.

[0031] After positioning the motorcycle-specific fuel nozzle body 1, the flow rate of gasoline during refueling can be adjusted through the fuel nozzle position hook 13. When the fuel level in the fuel tank rises, the air is compressed through the self-sealing air return hole 4, which can trigger the self-sealing device and thus stop refueling.

[0032] It is worth noting that, based on the survey data of various motorcycle fuel tank opening sizes, as the fuel tank volume increases, the fuel tank opening also increases. The inner diameter of the fuel tank opening ranges from 26 to 50 mm, with most concentrated between 30 and 33 mm. The depth of the fuel tank opening is concentrated between 30 and 50 mm. For fuel tanks where the depth can be measured, there is a crossbar at the bottom of the fuel tank opening to prevent the fuel nozzle from being inserted too deeply and blocking the refueling passage. For fuel tanks where there is no crossbar at the bottom, the depth cannot be measured and is generally greater than 50 mm. The outer diameter of the fuel tank opening usually ranges from 43 to 65 mm. Therefore, it can be concluded that the inner diameter of the fuel tank opening can be used to determine the positioning space. The minimum value for the diameter and the minimum value for the depth are generally 30 mm, which can solve the refueling positioning problem suitable for most fuel tank openings. However, for fuel tank openings with an inner diameter of less than 30 mm and a depth of less than 30 mm, it is recommended to lift the nozzle and refuel.

[0033] When it is necessary to insert the oil outlet pipe 12 into the motorcycle's fuel tank for refueling, the motorcycle-specific refueling nozzle body 1 must stand upright. In the radial direction, the oil outlet pipe 12 must be locked to the cylindrical surface inside the fuel tank opening. In the axial direction of the fuel tank depth, one method is to rely on the horizontal stop at the bottom of the fuel tank to prevent the nozzle from touching the bottom. In the case of a fuel tank without a horizontal stop, there must be a limiting measure in the axial direction. Therefore, a cylindrical pipe positioning block 2 and a conical pipe positioning block 21 are set in the middle of the oil outlet pipe 12.

[0034] This step, through the setting of the positioning component, can position the motorcycle-specific fuel nozzle body 1 when refueling the motorcycle, so that the motorcycle-specific fuel nozzle body 1 can stand upright at the fuel tank. This reduces the difficulty of the traditional fuel nozzle being firmly inserted into the motorcycle fuel tank opening, and the need for the refueling operator to hold the fuel nozzle in the air to operate it. As a result, the continuous exertion of the hand, shoulder and neck muscles can easily cause problems such as muscle strain, nerve compression and decreased work efficiency of the staff.

[0035] Example 2 like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, multiple sets of ventilation slots 5 are provided around the center of the oil outlet pipe 12 near the conical pipe positioning block 21.

[0036] An extended transparent gas collection hood 6 is connected to the middle of the oil outlet pipe 12 by a retaining spring.

[0037] The extended transparent gas collection hood 6 is made of elastic and transparent polyurethane material.

[0038] The inner diameter of the extended transparent vent 6 near the fuel tank is 70mm.

[0039] When refueling a motorcycle, there is another important issue: while positioning the fuel outlet pipe 12 and the fuel tank opening, it is also necessary to ensure that the fuel vapor is replaced and discharged during refueling. Otherwise, it will affect the fuel vapor recovery function. If the exhaust gap is insufficient, it will affect normal refueling and cause fuel vapor to spray back, which is counterproductive. Therefore, multiple ventilation grooves 5 are opened on the outer circumference of the middle part of the fuel outlet pipe 12 near the end face of the conical pipe positioning block 21 to ensure smooth air return.

[0040] During refueling, one end of the extended transparent vent cover 6 will press against the fuel tank to achieve a sealing effect, thereby reducing the occurrence of fuel vapor drifting into the external environment. Furthermore, since the extended transparent vent cover 6 is made of elastic transparent polyurethane material, it is convenient to collect fuel vapor while observing whether it will overflow after the tank is full. At the same time, the 70mm inner diameter of the extended transparent vent cover 6 can cover the fuel tank cavity, improving the sealing effect.

[0041] This step involves pressing the sealing surface of the extended transparent vent cover 6 tightly against the fuel tank opening when refueling the motorcycle. This allows for observation of the fuel level at the fuel tank opening and also relies on the elasticity of the extended transparent vent cover 6 to press against the outer surface of the fuel tank opening, reducing fuel splashing and collecting the fuel vapors displaced during refueling, thus avoiding safety, health, and environmental problems caused by the escape of fuel vapors.
