Abstract
Description
Technical Field
[0001] This utility model relates to the field of metrological verification technology, specifically to a fuel dispenser calibration metering tank. Background Technology
[0002] To ensure the accuracy of fuel dispensers at gas stations, each dispenser needs to undergo periodic calibration. The commonly used calibration method is the standard measuring instrument comparison method. This involves filling a standard measuring instrument with fuel from the nozzle and comparing the fuel dispenser's reading with the standard instrument's level to verify whether the dispenser is up to standard or requires adjustment or repair.
[0003] Many existing fuel dispenser calibration tanks lack the function of adjusting level, or the adjustment is very cumbersome, causing the tank to tilt to one side and become uneven during calibration, thus causing errors in the calibration work. Therefore, there is a need for a fuel dispenser calibration tank that can be leveled before calibration. Utility Model Content
[0004] To address this issue, this utility model provides a fuel dispenser calibration metering tank. Through the cooperation of the metering tank assembly and the metering tank fixing assembly, it solves the problem that many fuel dispenser calibration metering tanks lack the function of adjusting the level, or the adjustment is very troublesome, causing the metering tank to tilt to one side and not be level during calibration, thus causing errors in the calibration work.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fuel dispenser calibration metering tank, comprising a metering tank support, the metering tank support including a base, a bracket fixedly mounted on the top of the base, a cavity inside the bracket, a ball groove inside the cavity, a metering tank assembly inside the ball groove, and a metering tank fixing assembly inside the cavity, the metering tank assembly including a metering tank body, a ball head fixedly mounted on the outside of the metering tank body, and the metering tank fixing assembly including two bidirectional lead screws, a synchronous pulley fixedly mounted on the outside of each of the two bidirectional lead screws, a synchronous belt mounted on the outside of the two synchronous pulleys, and two ball head clamps mounted on the outside of the two bidirectional lead screws, with a knob connected to one end of one of the bidirectional lead screws.
[0006] Preferably, the ball head is located inside the ball groove and is slidably connected to the ball groove.
[0007] Preferably, the bidirectional lead screw passes through both sides of the cavity and is connected to both sides of the cavity via bearings.
[0008] Preferably, the threads at both ends of the bidirectional lead screw have opposite directions of rotation.
[0009] Preferably, the bidirectional lead screw passes through the ball head clamp and is connected to the ball head clamp via a thread.
[0010] Preferably, the timing belt is fitted over the two timing pulleys and driven by the two timing pulleys.
[0011] Preferably, the ball head clamp is disposed inside the cavity and slidably connected to the cavity, and one side of the ball head clamp extends into the ball groove and contacts the ball head.
[0012] The present invention has the following advantages:
[0013] 1. By cooperating with the ball head and the ball groove, the ball head can rotate inside the ball groove, thereby allowing the metering tank assembly to hang naturally and remain vertical. This ensures that when liquid enters the metering tank assembly, the liquid is horizontal, preventing the metering tank from tilting to one side and becoming non-horizontal during calibration, thus preventing errors in the calibration work.
[0014] 2. By rotating two bidirectional lead screws synchronously, the two lead screws are screwed in opposite directions at both ends, causing the two ball head clamps to move relative to each other towards the ball head at the center, clamping and fixing the ball head to prevent the metering tank assembly from shaking when adding oil into the metering tank body, thus ensuring the stability during calibration.

Detailed Implementation
[0023] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0024] See attached document Figure 1 -Attached Figure 5 The present invention provides a fuel dispenser calibration metering tank, including a metering tank support 1, a base 11, a bracket 12 fixedly mounted on the top of the base 11, a cavity 13 inside the bracket 12, a ball groove 14 inside the cavity 13, a metering tank assembly 2 inside the ball groove 14, and a metering tank fixing assembly 3 inside the cavity 13. The metering tank assembly 2 includes a metering tank body 21, a ball head 22 fixedly mounted on the outside of the metering tank body 21, and two bidirectional lead screws 32. A synchronous pulley 33 is fixedly mounted on the outside of each of the two bidirectional lead screws 32. A synchronous belt 34 is mounted on the outside of each of the two synchronous pulleys 33. Two ball head clamps 35 are mounted on the outside of each of the two bidirectional lead screws 32. A knob 31 is connected to one end of one of the bidirectional lead screws 32.
[0025] In this embodiment, in order to facilitate the horizontal adjustment of the metering tank assembly 2, the ball head 22 is rotated inside the ball groove 14 through the cooperation of the ball head 22 and the ball groove 14, so that the metering tank assembly 2 hangs down naturally and remains vertical. This ensures that when liquid enters the metering tank assembly 2, the liquid is horizontal, preventing the metering tank from tilting to one side and not being horizontal during the calibration, thus preventing errors in the calibration work. The two bidirectional lead screws 32 rotate synchronously, so that the two bidirectional lead screws 32 are screwed with opposite threads at both ends, causing the two ball head clamps 35 to move relative to the ball head 22 at the center, clamping and fixing the ball head 22, preventing the metering tank assembly 2 from shaking when oil is added into the metering tank body 21, and ensuring the stability during the calibration.
[0026] In order to enable the metering tank body 21 to swing while preventing the metering tank body 21 from detaching from the support 12, the device adopts the following technical solution: the ball head 22 is located inside the ball groove 14 and is slidably connected to the ball groove 14. Through the cooperation between the ball head 22 and the ball groove 14, the ball head 22 can rotate inside the ball groove 14, thereby allowing the metering tank assembly 2 to hang down naturally and maintain a vertical state. At the same time, through the matching of the ball head 22 and the ball groove 14, the metering tank body 21 is prevented from detaching from the support 12.
[0027] To prevent shaking of the metering tank body 21 during calibration, the device employs the following technical solution: a bidirectional lead screw 32 penetrates both side walls of the cavity 13 and is connected to both side walls of the cavity 13 via bearings; the threads at both ends of the bidirectional lead screw 32 rotate in opposite directions; the bidirectional lead screw 32 penetrates the ball head clamp 35 and is connected to the ball head clamp 35 via threads; a synchronous belt 34 is sleeved on the outside of the two synchronous pulleys 33 and is driven by the two synchronous pulleys 33; the ball head clamp 35 is located inside the cavity 13 and is slidably connected to the cavity 13; one side of the ball head clamp 35 extends into the ball groove 14 and is connected to the ball groove 14. After the heads 22 come into contact and the metering tank assembly 2 is adjusted to a horizontal state, the knob 31 is turned clockwise. The rotation of the knob 31 drives the connected bidirectional lead screw 32 to rotate. The rotation of the bidirectional lead screw 32 is achieved through the cooperation of the two synchronous pulleys 33 and the synchronous belt 34, so that the two bidirectional lead screws 32 rotate synchronously. In turn, the two bidirectional lead screws 32 are screwed in opposite directions at both ends, so that the two ball head clamps 35 move relative to the ball head 22 at the center, clamping and fixing the ball head 22 to prevent the metering tank assembly 2 from shaking when oil is added into the metering tank body 21, thus ensuring the stability during the calibration.
[0028] The usage process of this utility model is as follows: When using this utility model, an auxiliary counterweight device can be set on the outside of the metering tank body 21 using existing technology, so that the internal liquid level can be kept horizontal when the metering tank body 21 hangs naturally. When the metering tank support 1 is on an uneven ground, the ball head 22 can rotate inside the ball groove 14 through the cooperation of the ball head 22 and the ball groove 14, thereby making the metering tank assembly 2 hang vertically and ensure that the liquid is kept horizontal when liquid enters the metering tank assembly 2, preventing the metering tank from tilting to one side and not being horizontal during the calibration, thus preventing errors in the calibration work. To ensure a stable horizontal position, after the metering tank assembly 2 is leveled, the knob 31 is turned clockwise. The rotation of the knob 31 drives the connected bidirectional lead screw 32 to rotate. The rotation of the bidirectional lead screw 32, through the cooperation of the two synchronous pulleys 33 and the synchronous belt 34, causes the two bidirectional lead screws 32 to rotate synchronously. This causes the two bidirectional lead screws 32 to move towards the ball head 22 at the center through the opposite threads at both ends, clamping and fixing the ball head 22 to prevent the metering tank assembly 2 from shaking when oil is added to the metering tank body 21, thus ensuring stability during calibration.
[0029] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
