Description

Technical Field

[0001] This utility model relates to the field of oil volume verification, specifically a fuel dispenser verification mechanism with defoaming function. Background Technology

[0002] One step in calibrating a fuel dispenser is to check its output fuel volume. This is usually done using a calibration container, which typically has a graduated transparent tube on top. After the fuel is added, the volume scale is used to determine whether the added fuel is up to standard.

[0003] However, in existing technologies, the oil mixes with air during the addition process due to the impact. The mixed air rises and forms a bubble layer on top of the oil surface. The presence of the bubble layer makes accurate testing impossible, and the process usually requires the oil to stand still, which is inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a fuel dispenser calibration mechanism with defoaming function in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fuel dispenser calibration mechanism with defoaming function, comprising a calibration container, a transparent tube protruding upwards fixedly installed at the top of the calibration container, the transparent tube being engraved with volume scale, a feeding tube protruding upwards integrally formed at the top of the calibration container on one side of the transparent tube, a feeding funnel inserted into the top opening of the feeding tube, a guide mechanism fixedly installed at the top of the calibration container on the outside of the transparent tube, and a defoaming mechanism slidingly installed up and down on the outside of the guide mechanism.

[0006] As a further embodiment of this utility model: the guiding mechanism includes two guide rods fixedly installed on the top of the testing container and located outside the transparent tube.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3 In this embodiment of the present invention, a fuel dispenser calibration mechanism with defoaming function includes a calibration container 1. A transparent tube 4 protruding upward is fixedly installed at the top of the calibration container 1. Volume scale 5 is engraved on the transparent tube 4. A feeding tube 2 protruding upward is integrally formed at the top of the calibration container 1 on one side of the transparent tube 4. A feeding funnel 3 is inserted into the top opening of the feeding tube 2. A guide mechanism is fixedly installed at the top of the calibration container 1 on the outside of the transparent tube 4. A defoaming mechanism is slidably installed on the outside of the guide mechanism.

[0015] In this embodiment: First, when checking the amount of fuel dispensed by the fuel dispenser, the nozzle of the fuel nozzle is inserted into the feeding funnel 3, and then the fuel nozzle is turned on, and the fuel nozzle adds fuel to the testing container 1. After the fuel is added, the liquid level gradually rises and enters the transparent tube 4. After the fuel is added, the defoaming mechanism is pulled down along the guide mechanism. During this process, the defoaming mechanism is inserted into the transparent tube 4 until the bottom end of the defoaming mechanism contacts the air bubbles at the top of the liquid surface. When they come into contact, the air bubbles are punctured, thus achieving the defoaming function. After the defoaming is completed, a horizontal inspection can be performed to determine whether the amount of fuel added is too much or too little.

[0016] Please refer to this carefully. Figure 1 and Figure 2 The guiding mechanism includes two guide rods 6 fixedly installed on the top of the test container 1 and located outside the transparent tube 4. The top of the guide rod 6 is integrally formed with a limiting part. A fixed plate 7 protruding outward is welded to the middle section of the outer wall of the guide rod 6. A spring 9 is fixedly installed between the bottom end of the sliding plate 8 and the top end of the fixed plate 7. The spring 9 is sleeved on the outer periphery of the guide rod 6.

[0017] In this embodiment: when the defoaming mechanism is pulled downward, the defoaming mechanism slides downward along the outer wall of the guide rod 6. At this time, the defoaming mechanism pushes the top of the spring 9, and the spring 9 can be compressed. The restoring force of the compressed spring 9 provides an upward thrust to the defoaming mechanism. After the downward pressure applied to the defoaming mechanism is removed, the spring 9 returns to its original position and pushes the defoaming mechanism to return to its original position.

[0018] Please refer to this carefully. Figure 2 and Figure 3 The defoaming mechanism includes a sliding disk 8 that is slidably mounted on the outer wall of the guide rod 6 and located above the fixed disk 7. The outer periphery of both sliding disks 8 is integrally formed with a fixed rod 10 in an "L" shape. The top of the horizontal plate of the two fixed rods 10 is fixedly mounted with a handle 12. The bottom of the vertical rod of the two fixed rods 10 is fixedly connected to the top of a connecting disk 11. The diameter of the connecting disk 11 is smaller than the inner diameter of the transparent tube 4. The bottom of the connecting disk 11 is fixedly mounted with a plurality of downward protruding defoaming spikes 13. The bottom of the defoaming spikes 13 has a pointed conical structure.

[0019] In this embodiment: when a downward pulling force is applied to the defoaming mechanism, the sliding disk 8 drives the two fixed rods 10 to move downward. The fixed rods 10 push the connecting disk 11 to move downward. The connecting disk 11 enters the inner wall of the transparent tube 4. After entering the inner wall of the transparent tube 4, it drives the defoaming spikes 13 to move downward synchronously until the defoaming spikes 13 polish the bubbles at the top of the liquid surface, thereby increasing the defoaming speed and making it easier to observe the liquid level height more quickly.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
