Description

Technical Field

[0001] The utility model relates to the field of gasoline standard measuring instruments, in particular to a novel measuring instrument for measuring standard volume. Background Art

[0002] The meter for measuring standard volume of gasoline is a device specially used to detect the standard of fuel guns. It plays an important role in gas stations and other places. It is used in conjunction with a standard metal measuring instrument. Gasoline is added to the measuring instrument through the fuel gun and the volume of gasoline is observed and recorded to verify the accuracy of the fuel gun's measurement. There are many types of gasoline meters on the market, such as impeller type, volumetric flow meter, etc. Users need to choose according to actual conditions. Before use, they must ensure that the meter has been calibrated and meets the standards. Gas stations also need to calibrate fuel guns and meters regularly to ensure accuracy. During the calibration process, certified standard metal measuring instruments should be used and operated in accordance with the prescribed procedures. After calibration, the calibration certificate should be kept for inspection.

[0003] The inventor of this application found that there are the following problems in the practical use process:

[0004] During use, the existing standard volume meter requires the nozzle of the oil gun to be inserted into the oil inlet of the meter for refueling. However, if the nozzle of the oil gun is not fixed at this time, some problems may easily occur. For example, the nozzle of the oil gun may shake due to instability, causing gasoline to splash out, which will not only cause waste of resources, but also may bring safety hazards. At the same time, the unfixed nozzle of the oil gun may also affect the accuracy of refueling and the reading of the meter, thereby reducing the measurement accuracy and may even cause economic losses to gas stations and consumers. Therefore, ensuring that the nozzle of the oil gun can be firmly fixed when using the meter is an important link in ensuring the safe and accurate refueling process.

[0005] Therefore, it is necessary to provide a new type of meter for measuring standard volume to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is that during the refueling process, the meter shakes due to being not fixed, resulting in gasoline splashing, increased safety hazards, and affecting the accuracy of refueling and the accuracy of meter readings, and may even cause economic losses to gas stations and consumers. In view of the above-mentioned defects of the prior art, a new meter for measuring standard volume is provided.

[0007] To achieve the above object, the technical solution of the utility model is: a novel meter for measuring standard volume, comprising a meter, the meter comprising a storage bin, a metering bin and an oil inlet, the inner wall of the oil inlet is provided with a movable groove, the interior of the movable groove is provided with a clamping mechanism, the clamping mechanism comprises a spring sleeve, the interior of the movable groove is clamped and slidably provided with two sealing clamp rings, the inner ring diameters of the two sealing clamp rings are smaller than the refueling nozzle, and the spring sleeve is provided on both sides of the oil inlet;

[0008] Push rods are arranged on the outer sides of the two sealing clamps, and the push rods penetrate the oil inlet and the spring sleeve and extend to the outer side of the spring sleeve;

[0009] A card is slidably engaged inside the spring sleeve, and the card is fixedly connected to the connecting rod. A spring is abutted on one side of the card, and the spring is used to push the card to reset the sealing clamp ring. The engaging mechanism is used to clamp the refueling gun nozzle.

[0010] By adopting the above technical scheme, the storage bin, metering bin and specific oil inlet realize the storage, metering and input functions of oil. In particular, the locking mechanism setting of the oil inlet can effectively fix the refueling gun nozzle, prevent oil leakage, and improve the safety and efficiency of refueling.

[0011] It is further provided that support rods penetrate through both sides of the connecting rod, and connecting rods are installed on both sides of the support rods.

[0012] By adopting the above technical solution, the setting of the connecting rod passing through the support rod enhances the stability and structural strength of the locking mechanism. This structure enables the locking mechanism to provide a stable clamping force when fixing the refueling gun nozzle, preventing the gun nozzle from loosening or falling off during refueling.

[0013] It is further provided that a first support ring and a second support ring are respectively installed at one end of the two connecting rods, the first support ring and the second support ring are both provided in a semi-arc structure, and the first support ring and the second support ring can both abut against the oil inlet.

[0014] By adopting the above technical solution, the provision of the two support rings not only enhances the operational convenience of the locking mechanism, allowing the operator to more easily control the opening and closing of the locking mechanism, but they can also help open the sealing clamp ring after refueling is completed to ensure that the oil flows out smoothly without obstruction.

[0015] It is further provided that the first support ring and the second support ring are used to open two sealing clamps to prevent the sealing clamps from affecting the oil flow.

[0016] By adopting the above technical solution, the sealing clamp ring is opened through the support ring, which effectively prevents the oil from being unable to flow out smoothly due to the obstruction of the sealing clamp ring after refueling, thereby improving the refueling efficiency and reducing oil residue and waste.

[0017] It is further provided that a metering bin is provided on the top of the storage bin, and the storage bin is communicated with the metering bin.

[0018] By adopting the above technical solution, the through-connection setting of the storage bin and the metering bin allows the oil to flow smoothly from the storage bin into the metering bin, which is convenient for accurate metering of the refueling amount. This setting simplifies the oil flow path, reduces flow resistance, and improves metering accuracy.

[0019] It is further provided that visual ports are provided on both sides of the metering bin, and a meter is provided on the outer surface of the visual port.

[0020] By adopting the above technical solution, the setting of the visual port and the meter enables the operator to intuitively observe the oil volume in the metering bin and the real-time data of refueling, which is convenient for monitoring the refueling process and ensuring the accuracy of the refueling amount.

[0021] It is further provided that the material of the meter is stainless steel, and the material of the sealing clamp ring is rubber.

[0022] By adopting the above technical solution, stainless steel is used as the main material of the meter, which ensures the structural strength and corrosion resistance of the meter and extends its service life. The sealing clamp is made of rubber material, which provides good sealing and flexibility and effectively prevents oil leakage.

[0023] It is further provided that a sealing block is inserted into the top of the oil inlet, and the sealing block is engaged with a sealing clamp ring.

[0024] By adopting the above technical solution, the engagement arrangement of the sealing block and the sealing clamp ring further enhances the sealing of the oil inlet, prevents leakage of oil in a non-oiling state, and improves the safety and environmental protection of the meter.

[0025] It is further provided that a non-slip pad is adhered to the bottom of the meter, the material of the non-slip pad is rubber, and the bottom of the non-slip pad is provided with non-slip grooves.

[0026] By adopting the above technical solution, the anti-skid pad not only increases the stability of the meter when it is placed, preventing it from sliding or tipping over, but the rubber material and anti-skid pattern also further enhance the anti-skid effect, ensuring the safety of the meter during use.

[0027] Compared with the related art, the novel meter for measuring standard volume provided by the utility model has the following beneficial effects:

[0028] The utility model provides a novel meter for measuring standard volume. A clamping mechanism is arranged, wherein the oil inlet is a channel for gasoline to enter the meter. Reasonable arrangement can ensure refueling efficiency and safety. The movable groove provides installation and activity space for the clamping mechanism, ensures its normal operation without affecting refueling. The clamping mechanism prevents shaking by clamping the oil gun mouth, improves the safety and accuracy of refueling. The sealing clamp ring can fit tightly to the oil gun mouth to prevent gasoline leakage. The inner ring diameter is set smaller than the refueling gun mouth to firmly clamp the oil gun mouth. The push rod can adjust the position of the sealing clamp ring to adapt to oil gun mouths of different diameters, improve the versatility of the equipment, and facilitate operators to manually control the clamping mechanism. The spring sleeve protects the spring and the card to ensure that they work stably, and effectively uses the spring elastic force to push the card and the sealing clamp ring to reset. The card controls the position and clamping force of the sealing clamp ring through the spring, and is a key component for realizing stable fixation of the oil gun mouth. The spring provides continuous thrust, so that the sealing clamp ring fits tightly to the oil gun mouth, maintains a stable clamping force, and ensures that the clamping mechanism still has good performance after long-term use.

[0029] The utility model provides a novel meter for measuring standard volume, which adopts a support rod, a connecting rod, a first supporting ring and a second supporting ring, wherein the structural arrangement of the connecting rod and the support rod enhances the stability and supporting force of the engaging mechanism, ensuring that the mechanism is stable and not easy to loosen during refueling, and at the same time, the connecting rod can effectively transmit the operating force of the push rod to achieve stable clamping of the oil gun nozzle, and the semi-arc arrangement of the first supporting ring and the second supporting ring is convenient for operators to hold and push, thereby improving the convenience of operation, and at the same time protecting the oil inlet from damage when the oil gun nozzle is clamped, in addition, the two supporting rings can open the sealing clamp ring when the oil gun nozzle is released, thereby ensuring smooth oil discharge and improving refueling efficiency, while also providing operational flexibility, and facilitating adjustment of the position and state of the sealing clamp ring according to needs.

DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0036] Embodiment 1:

[0037] like Figure 1 As shown, the novel metering device for measuring standard volume of the utility model comprises a metering device 1, which comprises a storage bin 101, a metering bin 102 and an oil inlet 104. The inner wall of the oil inlet 104 is provided with a movable groove 105, and a clamping mechanism 3 is arranged inside the movable groove 105. The clamping mechanism 3 comprises a spring sleeve 309. The inner clamping and sliding of the movable groove 105 has two sealing clamp rings 301. The inner ring diameters of the two sealing clamp rings 301 are smaller than the refueling nozzle. The spring sleeves 309 are arranged on both sides of the oil inlet 104.

[0038] A push rod 302 is disposed on the outer side of each of the two sealing collars 301 , and the push rod 302 penetrates the oil inlet 104 and the spring sleeve 309 , and extends to the outer side of the spring sleeve 309 ;

[0039] The spring sleeve 309 has a card 303 that is snap-fitted and slidable inside, and the card 303 is fixedly connected to the connecting rod 306. A spring 304 is abutted on one side of the card 303. The spring 304 is used to push the card 303 to reset the sealing ring 301. The snap-fit ​​mechanism 3 is used to clamp the refueling nozzle. This arrangement realizes automatic clamping and tight sealing of the refueling nozzle through a sophisticated mechanical structure, especially the snap-fit ​​mechanism 3, which not only improves the safety and efficiency during the refueling process, but also ensures that the oil will not leak through structures such as the spring sleeve 309 and the sealing ring 301, thereby protecting the environment and the safety of users.

[0040] like Figure 2 As shown, support rods 305 penetrate both sides of the connecting rod 306, and connecting rods 306 are installed on both sides of the support rod 305. The interactive arrangement of the connecting rod 306 and the support rod 305 enhances the structural stability and clamping strength of the engaging mechanism. This arrangement enables the refueling gun muzzle to be firmly fixed to the oil inlet 104 during the refueling process, thereby preventing safety problems caused by loosening or falling off.

[0041] like Figure 3As shown, a first support ring 307 and a second support ring 308 are respectively installed at one end of the two connecting rods 306. The first support ring 307 and the second support ring 308 are both arranged in a semi-arc structure, and the first support ring 307 and the second support ring 308 can both abut against the oil inlet 104. The semi-arc structure of the first support ring 307 and the second support ring 308 makes it more convenient for the operator to control the locking mechanism. At the same time, they also play a role in assisting the opening of the sealing clamping ring 301 to ensure that the oil can flow out smoothly after refueling is completed, thereby improving the overall work efficiency.

[0042] like Figure 3 As shown, the first support ring 307 and the second support ring 308 are used to open the two sealing clamps 301 to prevent the sealing clamps 301 from affecting the oil output. With the assistance of the first support ring 307 and the second support ring 308, the sealing clamps 301 can be opened in time after refueling is completed, avoiding the oil outflow caused by the closed clamps, which not only improves the oil output efficiency, but also reduces the oil residue in the equipment.

[0043] Embodiment 2:

[0044] like Figure 3 As shown, a metering bin 102 is arranged on the top of the storage bin 101, and the storage bin 101 is connected with the metering bin 102. The connecting arrangement of the storage bin 101 and the metering bin 102 enables the oil to flow smoothly from the storage bin into the metering bin, thereby ensuring the accuracy and continuity of the metering. This arrangement simplifies the oil flow path and improves the overall work efficiency.

[0045] like Figure 3 As shown, visual ports 103 are provided on both sides of the metering bin 102, and a meter is provided on the outer surface of the visual port 103. The setting of the visual port 103 and the meter enables the operator to intuitively monitor the oil volume in the metering bin 102 and the real-time data of refueling, which greatly improves the transparency and accuracy of the refueling process and facilitates precise control of the refueling amount.

[0046] like Figure 3 As shown, the material of the meter 1 is stainless steel, and the material of the sealing clamp ring 301 is rubber. Using stainless steel as the main material of the meter 1 ensures its structural strength and corrosion resistance, thereby extending its service life, and the sealing clamp ring 301 is made of rubber, which provides good sealing and flexibility, and effectively prevents oil leakage.

[0047] like Figure 3As shown, a sealing block is inserted into the top of the oil inlet 104, and the sealing block is engaged with the sealing retaining ring 301. The tight fit between the sealing block and the sealing retaining ring 301 further enhances the sealing performance of the oil inlet 104. This arrangement effectively prevents leakage of oil in a non-refueling state, thereby improving the safety and environmental protection of the equipment.

[0048] like Figure 4 As shown, the bottom of the meter 1 is adhered with an anti-skid pad 2, which is made of rubber and has anti-skid patterns on the bottom. The anti-skid pad 2 not only improves the stability of the meter when it is placed, preventing it from sliding or tipping over, but also its rubber material and specially designed anti-skid patterns further enhance the anti-skid effect. This ensures safety during use and avoids accidents caused by equipment sliding.

[0049] In practice, first, during the insertion process, the nozzle of the refueling gun will contact the two sealing clamp rings 301. Since the inner ring diameter of the sealing clamp ring 301 is smaller than that of the nozzle of the refueling gun, it will be pushed away;

[0050] When the sealing collar 301 is pushed open, the push rod 302 on the outside thereof will move accordingly and push the card 303 inside the spring sleeve 309. In this process, the spring 304 will be compressed;

[0051] When refueling starts, the oil flows into the oil inlet 104 through the refueling gun, and then enters the metering bin 102 through the storage bin 101. During the oil flow, the amount and speed of refueling can be observed and recorded through the visual ports 103 on both sides of the metering bin 102 and the metering gauge on the outer surface;

[0052] After refueling, the refueling nozzle needs to be pulled out. At this time, the connecting rod 306 can be pulled outward. The movement of the connecting rod 306 will drive the first supporting ring 307 and the second supporting ring 308 to open the sealing clamp ring 301, thereby releasing the fixing of the refueling nozzle;

[0053] Pull out the refueling gun nozzle to complete the refueling process. Finally, the oil inlet 104 can be closed by a sealing block to prevent dust and impurities from entering. At the same time, since the anti-skid pad 2 is adhered to the bottom of the meter 1, it can ensure that the equipment remains stable during use.

[0054] The advantages of this technical solution in practical applications include but are not limited to the following:

[0055] 1. By setting the locking mechanism, especially the setting of the oil inlet, it can ensure that the gasoline enters the meter quickly and safely, thereby improving the efficiency of refueling and ensuring the safety of the operation process;

[0056] 2. The clamping mechanism effectively prevents shaking during refueling by clamping the oil gun nozzle, which not only improves the safety of refueling, but also improves the accuracy of the refueling amount;

[0057] 3. The setting of the sealing clamp ring can closely fit the oil gun nozzles of different diameters, effectively preventing gasoline leakage. At the same time, the adjustment function of the push rod enables the equipment to adapt to a variety of oil gun nozzles of different specifications, greatly enhancing the versatility of the equipment;

[0058] 4. The spring sleeve protects the spring and the card to ensure that these key components can work stably. In addition, the setting of the spring enables the operator to feel a continuous and stable feedback force when adjusting the locking mechanism, which is convenient for manual control;

[0059] 5. The structural setting of the support rod and the connecting rod not only enhances the stability of the locking mechanism, but also provides it with strong support force, ensuring that the mechanism can remain stable and not easy to loosen during the refueling process;

[0060] 6. The semi-arc setting of the first support ring and the second support ring is not only convenient for the operator to hold and push, but also can protect the oil inlet from damage when clamping the oil gun nozzle. More importantly, when releasing the oil gun nozzle, the two support rings can ensure that the sealing clamp is fully open, thereby ensuring the smoothness of the oil flow and further improving the refueling efficiency.
