Description

Technical Field

[0001] This utility model belongs to the field of metrological verification technology, specifically an auxiliary device for the verification of standard metal measuring instruments. Background Technology

[0002] Standard metal measuring instruments, also known as "fairness containers," play a crucial role in ensuring the accuracy of fuel quantities sold. Marine and land-based refueling stations periodically submit their standard metal measuring instruments for testing. These instruments are used to verify the accuracy of the fuel dispenser's metering system, ensuring the correct fuel quantity is delivered. When purchasing fuel, consumers can request to see the measurement traceability record of the standard metal measuring instrument to guarantee fairness and accuracy in fuel measurement.

[0003] According to JJG259-2005 "Verification Procedure for Standard Metal Measuring Instruments", standard metal measuring instruments should be in a horizontal position during traceability. However, due to manufacturing limitations, the height adjustment of standard metal measuring instruments is limited, and rusting after long-term use can render them unable to adjust for horizontality. Furthermore, environmental factors, such as the continuous vibration of the deck caused by the generator on a ship during the operation of a marine refueling machine, can lead to changes in the horizontality of the standard metal measuring instrument, resulting in errors in traceability.

[0004] Therefore, how to provide an auxiliary device for the calibration of standard metal measuring instruments that can adjust the level and stabilize the liquid level reading has become a problem that needs to be considered by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for the calibration of standard metal measuring instruments. This utility model has a height adjustment mechanism installed in the placement platform, which can adjust the height of each leg of the standard metal measuring instrument to achieve horizontal adjustment. The vibration isolator can isolate vibration and stabilize the liquid level reading of the standard metal measuring instrument.

[0006] To achieve the above objectives, this utility model provides an auxiliary device for the calibration of standard metal measuring instruments, including a placement platform and a vibration isolator. The placement platform is provided with support legs, and the vibration isolator is located at the bottom end of the support legs. The placement platform is provided with several height adjustment mechanisms, each of which includes a lifting seat, a self-locking screw, a first bevel gear, and a second bevel gear. The self-locking screw is rotatably mounted in the placement platform. The lifting seat is sleeved on the surface of the self-locking screw and threadedly connected to the self-locking screw. The lifting seat can extend out of the placement platform by being driven by the self-locking screw. The first bevel gear is located at the bottom end of the self-locking screw, and the second bevel gear is located on one side of the first bevel gear. The second bevel gear is rotatably mounted on the placement platform. The first bevel gear and the second bevel gear form a bevel gear pair. The tail end shaft of the second bevel gear passes through the placement platform and is provided with a lateral limiting protrusion.

[0007] Furthermore, limit blocks are provided on the left and right sides of the bottom of the lifting seat, and a sliding groove is provided in the placement platform corresponding to the limit blocks.

[0008] Furthermore, the top of the lifting seat is hollow, and an anti-slip pad is provided on the inner side of the lifting seat.

[0009] Furthermore, it also includes a crank handle, one end of which is provided with a locking groove for locking the lateral limiting protrusion.

[0010] Furthermore, the vibration isolator is a rubber vibration isolator.

[0011] Furthermore, it also includes a bubble level, which is placed on the surface of a standard metal measuring instrument to detect the leveling of the standard metal measuring instrument.

[0012] The beneficial effects of the utility model are:

[0013] This invention allows for the horizontal adjustment of the standard metal measuring instrument by placing it on the height adjustment mechanism of the platform. It also allows for the adjustment of the instrument's height according to actual needs. The rubber vibration isolator effectively suppresses the amplitude of resonance by utilizing the high damping characteristics of rubber, thereby isolating the vibration of the deck and achieving a stable reading of the liquid level in the standard metal measuring instrument.

[0021] Example 1

[0022] like Figure 1-4 As shown, this embodiment discloses an auxiliary device for calibrating standard metal measuring instruments, including a placement platform 1 and a vibration isolator 2. The placement platform 1 is provided with support legs 3, and the vibration isolator 2 is installed at the bottom end of the support legs 3. In this embodiment, the vibration isolator 2 is a rubber vibration isolator, which has high elasticity and good vibration isolation performance, and can effectively isolate vibration, impact and noise. Several height adjustment mechanisms are provided in the placement platform 1 corresponding to the support legs of the standard metal measuring instrument 4. In this embodiment, there are three height adjustment mechanisms.

[0023] Specifically, the height adjustment mechanism includes a lifting seat 5, a self-locking screw 6, a first bevel gear 7, and a second bevel gear 8. The top of the lifting seat 5 is hollow, and an anti-slip pad 9 is provided on the inner side of the top, which can be used as a support for placing the standard metal measuring instrument 4. The lifting seat 5 has an internal thread. The self-locking screw 6 is rotatably mounted in the placement platform 1. The lifting seat 5 is sleeved on the surface of the self-locking screw 6 and threadedly connected to the self-locking screw 6. The lifting seat 5 can extend out of the placement platform 1 through the drive of the self-locking screw 6. In this embodiment, limit blocks 10 are also provided on the left and right sides of the bottom of the lifting seat 5. The placement platform 1 is provided with a sliding groove corresponding to the limit block 10, which can prevent the lifting seat 5 from rotating with the self-locking screw 6.

[0024] The first bevel gear 7 is located at the bottom end of the self-locking screw 6, and the second bevel gear 8 is located on one side of the first bevel gear 7. The second bevel gear 8 is rotatably mounted on the placement platform 1. The first bevel gear 7 and the second bevel gear 8 form a bevel gear pair. The tail end shaft of the second bevel gear 8 passes through the placement platform 1 and is provided with a lateral limiting protrusion. This utility model can drive the second bevel gear 8 to drive the rotation of the first bevel gear 7, thereby driving the rotation of the self-locking screw 6, so that the lifting seat 5 extends and retracts from the placement platform 1.

[0025] As a preferred embodiment of this utility model, it also includes a crank handle (not shown in the figure), one end of which is provided with a locking groove for locking the lateral limiting protrusion, so that the height adjustment mechanism can be easily adjusted by the crank handle.

[0026] As a preferred embodiment of the present invention, it also includes a bubble level 11, which is placed on the surface of the standard metal measuring instrument 4 and is used to detect the leveling effect of the standard metal measuring instrument 4.

[0027] When using this utility model's calibration auxiliary device, it is fixed to the ground or the deck of a ship via a vibration isolator 2. The standard metal measuring instrument 4 is placed in the height adjustment mechanism of the placement platform 1. The vibration on the deck is isolated by the vibration isolator 2, and the height of the standard metal measuring instrument 4 is adjusted by a crank handle. Then, the bubble level 11 is placed on the surface of the standard metal measuring instrument 4, and the height adjustment mechanism in different directions is adjusted by a crank handle to achieve the leveling of the standard metal measuring instrument 4.

[0028] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
