Description

Technical Field

[0001] This application relates to the field of oil meter calibration equipment technology, and more specifically, to a standard metering tank structure for oil gun docking. Background Technology

[0002] Fuel dispensers require regular inspections during use to ensure that their refueling accuracy remains within standard limits. These inspections primarily employ a volumetric comparison method, typically using a standard measuring container. Figure 4 As shown, the upper part of the standard measuring tank is a filling funnel 200. During the testing process, the fuel nozzle (fuel gun) is inserted into the filling funnel 200 to dispense fuel. To ensure the accuracy of the volume measurement of the standard measuring tank 100, a slender measuring neck 110 and a visual indicator tube 120 for observing the liquid level are designed on the upper part of the measuring device. A measuring element 130 (vernier caliper) parallel to the measuring neck 110 is installed at the visual indicator tube 120 to read the accurate liquid level value. During routine inspection, the fuel dispenser adds a certain amount of fuel to the standard measuring tank 100, typically 20L-100L, for example, a 50L measuring tank can be used. The position of the vernier caliper is adjusted on the visual indicator tube 120 of the standard measuring tank 100, and the liquid level is read visually.

[0003] However, when using the current standard metering tank, the nozzle of the refueling gun is inserted into the bottom hole of the filling funnel 200 (the opening of the metering neck tube 110), and the gun body is placed on the upper edge of the filling funnel, or the inspector holds the gun in their hand, so that the gun is directed towards the filling funnel to dispense oil. Placing the gun on the upper edge of the filling funnel is prone to shaking during processing, resulting in instability. If the inspector holds the gun in their hand to dispense oil, it is even more strenuous, leading to the inconvenience of using the standard metering tank.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this application is to provide a standard metering tank structure for connecting oil guns, which solves the problem of inconvenience caused by unstable fixing of oil guns when using standard metering tanks in the prior art.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] This application provides a standard metering tank structure for connecting oil guns, including: a metering tank, a filling funnel on the metering tank, a gun mounting groove on the upper edge of the filling funnel, the gun mounting groove being recessed into the upper surface of the filling funnel, the gun mounting groove being used to place the oil gun in the gun mounting groove and continuously dispense oil into the filling funnel.

[0008] Optionally, the gun mounting slot includes two vertically arranged gun mounting sides and a gun mounting bottom edge connected to the lower part of the two gun mounting sides;

[0009] The upper side of the gun loading slot is open to form an opening for inserting the oil gun.

[0010] Optionally, the contour of the bottom edge of the gun is matched with the outer contour of the mating part of the oil gun.

[0011] Optionally, the bottom edge of the gun is set horizontally.

[0012] Optionally, guide ramps are inclined on both sides of the opening of the gun mounting slot, and the distance between the guide ramps on both sides gradually decreases from top to bottom.

[0013] Optionally, the filling funnel includes: a bottom funnel, which is located above and connected to the metering tank;

[0014] The top funnel is connected above the bottom funnel, and the diameter of the top funnel is larger than that of the bottom funnel. The gun loading slot is opened on the top funnel.

[0015] Optionally, the top funnel is connected to the bottom funnel by an inclined hood, the inner diameter of which gradually decreases from top to bottom.

[0016] Optionally, the inclined cover and the top funnel are integrally bent and formed;

[0017] The inclined cover is welded and fixed to the top edge of the bottom funnel.

[0018] Optionally, the filling funnel is a stainless steel funnel.

[0019] Optionally, the metering tank is connected to the filling funnel through a metering neck tube, and the metering tank is equipped with a visual liquid indicator tube and a measuring element;

[0020] The visible liquid indicator tube connects the filling funnel and the metering tank in the vertical direction;

[0021] The measuring element is located on one side of the visual liquid indicator tube and is used to measure the liquid level height in the visual liquid indicator tube.

[0022] The beneficial effects of the standard metering tank structure for fuel nozzle docking provided in this application are at least as follows: By providing a nozzle mounting groove on the upper edge of the filling funnel, during fuel nozzle routine inspection, the nozzle head is inserted into the bottom hole of the filling funnel, and the nozzle body is inserted into the mounting groove, allowing the open nozzle to continuously dispense fuel into the filling funnel. The fuel dispensed from the nozzle enters the metering tank through the filling funnel for convenient testing. The fuel nozzle is stably held in the mounting groove, preventing lateral movement during dispensing, thus ensuring greater stability. Furthermore, during fuel dispensing, the inspector does not need to hold the fuel nozzle continuously, greatly reducing the workload of the inspector and making the routine inspection process of the fuel dispenser more convenient.

[0032] like Figure 1 , Figure 2 As shown, this embodiment proposes a standard metering tank structure for fuel nozzle docking. It is a structural improvement on an existing standard metering tank, without altering the fuel metering portion, and conforms to standard specifications. The standard metering tank structure of this embodiment mainly includes: a metering tank 100 and a filling funnel 200. The filling funnel 200 is positioned above the metering tank 100 and is mainly used to receive fuel input from the fuel nozzle and guide the fuel into the metering tank 100. The metering tank 100 is primarily used for fuel metering and adopts the existing standard metering tank 100 design that conforms to metering standards. In this embodiment, a nozzle mounting groove 210 is formed on the upper edge of the filling funnel 200. The nozzle mounting groove 210 is recessed into the upper surface of the filling funnel 200 and is used to place the fuel nozzle within the nozzle mounting groove 210 and continuously dispense fuel into the filling funnel 200. When in use, the nozzle body can be inserted into the nozzle slot 210, so that the outlet of the nozzle head is located inside the filling funnel 200 and continuously feeds fuel into the filling funnel 200.

[0033] like Figure 1 , Figure 2 As shown, the standard metering tank structure for connecting the oil gun in this embodiment has a gun mounting groove 210 on the upper edge of the filling funnel 200. During oil gun inspection, the nozzle of the oil gun is inserted into the bottom hole of the filling funnel 200, so that the oil gun is inserted into the gun mounting groove 210. The open oil gun continuously dispenses oil into the filling funnel 200. The oil dispensed by the oil gun enters the metering tank 100 through the filling funnel 200 for easy testing. The oil gun can be stably locked in the gun mounting groove 210, and it will not wobble from side to side during the oil dispensing process, making it more stable.

[0034] like Figure 2 , Figure 3 , Figure 4As shown, in this embodiment, the metering tank 100 is connected to the filling funnel 200 via a metering neck tube 110, and the opening of the metering neck tube 110 serves as the bottom hole of the filling funnel 200. The metering tank 100 is equipped with a visual indicator tube 120 and a measuring element 130; the visual indicator tube 120 connects the filling funnel 200 and the metering tank 100 in a vertical direction; the measuring element 130 is located on one side of the visual indicator tube 120 and is used to measure the liquid level in the visual indicator tube 120. Specifically, the lower part of the filling funnel 200 is connected to the metering neck tube 110, and the lower part of the metering neck tube 110 is connected to the metering tank 100. Fuel enters the metering tank 100 through the metering neck tube 110. As the amount of fuel in the metering tank 100 increases, the fuel enters the visual indicator tube 120, allowing the fuel level to be observed. The measuring element 130 can be a vernier caliper. The vernier caliper is set parallel to the visible liquid level tube 120. The vernier caliper's vernier 131 is adjusted according to the liquid level in the visible liquid level tube 120, allowing the vernier 131 to be aligned with the liquid level. The specific liquid level can then be read visually, thus obtaining the corresponding fuel capacity in the metering tank 100. This capacity represents the actual fuel dispensing volume of the fuel dispenser. By comparing this with the fuel dispensing volume displayed on the gas dispenser, the quality of the fuel dispenser can be determined. In this embodiment, the metering tank 100, metering neck tube 110, visible liquid level tube 120, and measuring element 130 all conform to metrological standards and can directly adopt existing standard structures.

[0035] like Figure 2 , Figure 3 As shown, the filling funnel 200 in this embodiment further includes a bottom funnel 220 and a top funnel 230. The bottom funnel 220 is located above and connected to the metering tank 100; the top funnel 230 is connected above the bottom funnel 220, and the diameter of the top funnel 230 is larger than the diameter of the bottom funnel 220. The gun-filling slot 210 is formed on the top funnel 230. In the specific structure, the bottom funnel 220 is connected to the metering neck tube 110. The bottom funnel 220 can adopt the existing funnel structure of the metering tank 100. The top funnel 230 is added to the bottom funnel 220, and the gun-filling slot 210 is only formed on the top funnel 230, so as not to affect the guiding effect of the original funnel structure. Furthermore, by adding a top funnel 230 to the bottom funnel 220, the bottom funnel 220 can be raised. The top funnel 230, through its blocking effect, can prevent the foam generated by the fuel output from the fuel nozzle from accumulating and overflowing from the filling funnel 200. Designing the inner diameter of the top funnel 230 to be larger than that of the bottom funnel 220 also increases the overall volume of the filling funnel 200. This reduces the height of fuel entering the filling funnel 200 per unit time and also prevents excessive foam accumulation per unit time, thus ensuring that fuel does not leak from the filling funnel 200 during input and making fuel input more stable during testing.

[0036] Furthermore, by designing the inner diameter of the top funnel 230 to be larger than that of the bottom funnel 220, the overall volume of the filling funnel 200 is increased. Therefore, when the oil gun is inserted into the gun slot 210, the portion of the gun tip extending into the top funnel 230 will be greater than when the operator holds the oil gun; that is, the oil gun tip will penetrate the filling funnel 200 more deeply. Thus, increasing the inner diameter of the top funnel 230 prevents the oil gun tip from entering the top funnel 230 too deeply after insertion into the gun slot 210. For example, the outlet of the gun tip can be positioned downwards, closer to the center of the top funnel 230, resulting in a more stable oil flow from the oil gun.

[0037] like Figure 2 , Figure 3 As shown, in this embodiment, the top funnel 230 is connected to the bottom funnel 220 via an inclined cover 240, the inner diameter of which gradually decreases from top to bottom. Specifically, the inclined cover 240 is located at the bottom of the top funnel 230 and connected to the upper part of the bottom funnel 220. The inclined cover 240 smoothly connects the larger inner diameter top funnel 230 to the smaller inner diameter bottom funnel 220, allowing fuel in the top funnel 230 to flow smoothly into the smaller bottom funnel 220. This ensures stable flow of the input fuel within the filling funnel 200. Furthermore, the inclined cover 240 allows the fuel input from the fuel gun to flow smoothly into the metering tank 100 under gravity, reducing fuel residue in the filling funnel 200 and making fuel metering more accurate.

[0038] like Figure 2 , Figure 3 As shown, in this embodiment, the inclined cover 240 and the top funnel 230 are integrally bent and formed. The inclined cover 240 and the top funnel 230 are formed by bending sheet metal to form an integral structure. When the oil gun is inserted into the gun slot 210 of the top funnel 230, the top funnel 230 supports the oil gun, and the inclined cover 240 supports the top funnel 230. Therefore, in order to ensure the stability of the support structure, setting it as an integral structure can enhance the load-bearing capacity.

[0039] like Figure 2 , Figure 3 As shown, in this embodiment, the inclined cover 240 is welded and fixed to the top edge of the bottom funnel 220. Welding makes the connection between the inclined cover 240 and the bottom funnel 220 more secure, and the welded fixing has good sealing performance, making leakage less likely.

[0040] like Figure 2 , Figure 3As shown, further, the gun mounting slot 210 of this embodiment includes two vertically arranged gun mounting sides 211 and a gun mounting bottom edge 212 connected to the lower part of the two gun mounting sides 211; the upper side of the gun mounting slot 210 is open to form an opening for inserting the oil gun. In the specific structure, the two gun mounting sides 211 of the gun mounting slot 210 are spaced apart circumferentially, and the two gun mounting sides 211 can limit the docking part of the oil gun inserted into the gun mounting slot 210, so that the oil gun inserted into the gun mounting slot 210 will not wobble on both sides. It should be noted that the docking part of the oil gun is the original gun body structure of the oil gun, which can be smoothly inserted into the gun mounting slot 210, thus solving the technical problem of this application.

[0041] The mounting base 212 of this embodiment can adopt different structural forms. For example, in the first form: the mounting base 212 of this embodiment is set horizontally. Specifically, the mounting base 212 directly adopts a horizontal bottom surface, so that the horizontal bottom surface and the vertically set mounting sides 211 on both sides form a square groove with an opening. The horizontal bottom surface can support and hold the oil gun, so that the oil gun can be placed in the mounting groove 210. In the second form: the outline of the mounting base 212 matches the outer outline of the oil gun's docking part. Specifically, the mounting base can be arc-shaped, and its arc-shaped outline matches the outer outline of the oil gun's docking part (the part inserted into the mounting groove 210). This makes the oil gun more stable when placed in the mounting groove 210.

[0042] like Figure 2 , Figure 3 As shown, further, in this embodiment, guide slopes 213 are inclinedly provided on both sides of the opening of the gun mounting slot 210, and the distance between the guide slopes 213 on both sides gradually decreases from top to bottom. Through the guide slopes 213 on both sides, the upper end of the opening of the gun mounting slot 210 forms a flared mouth. When the oil gun is about to be inserted into the gun mounting slot 210, it is first guided by the flared guide slopes 213 at the opening, so that the docking part of the oil gun can smoothly pass through the opening and be inserted into the gun mounting slot 210, which facilitates the installation of the oil gun and the gun mounting slot 210.

[0043] like Figure 3 As shown, in this embodiment, the filling funnel 200 is further provided with multiple nozzle slots 210, each with a different width to accommodate different types of refueling nozzles. For example, refueling nozzles are typically OPW or JV models. At least two nozzle slots 210 can be provided to accommodate either OPW or JV refueling nozzles respectively.

[0044] like Figure 2 , Figure 3As shown, in this embodiment, the filling funnel 200 is a stainless steel funnel. Specifically, the top funnel 230, the inclined cover 240, the bottom funnel 220, and the metering tank 100 can all be made of stainless steel. This provides advantages such as good structural rigidity, strong load-bearing capacity, durability, and guaranteed product quality.

[0045] In summary, the standard metering tank structure for fuel nozzle docking proposed in this application allows the fuel nozzle to be placed on a filling funnel, with the open nozzle continuously dispensing fuel into the funnel. The fuel dispensed from the nozzle enters the metering tank through the funnel for easy testing. The fuel nozzle is stably secured within the nozzle slot, making the scheduled maintenance process of the fuel dispenser more convenient.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
