Description

Technical Field

[0001] This utility model relates to the field of metrology and testing equipment technology, and in particular to a metal container for metrology verification of fuel dispensers. Background Technology

[0002] As a measuring instrument used for trade settlement, the accuracy of fuel dispensers directly affects the vital interests of operators and consumers. During the verification process, standard metal containers are usually equipped with glass fuel level tubes and movable finger rings. Operators inject a standard amount of fuel into the container and observe whether the liquid level in the fuel level tube is aligned with the scale line of the finger ring to determine whether the fuel dispenser's measurement value is accurate. Due to temperature changes, container calibration, or the requirements of different verification procedures, the finger ring needs to be precisely moved to a new position and re-fixed.

[0003] In existing technologies, the fixing methods of finger rings are generally quite traditional, mostly using screw-tightening locking structures or purely friction-based locking structures. When the position of the finger ring needs to be adjusted, the operator needs to use a screwdriver to loosen and tighten it, which is a cumbersome process and reduces the efficiency of on-site verification. Since the verification work environment is usually outdoors, the container is exposed to the air for a long time, and the metal screws and screw holes may get stuck due to rust or oil congealing, making adjustment extremely difficult or even impossible, which seriously affects the normal progress of the verification work.

[0004] Therefore, this utility model proposes a metal container for metering and verification of fuel dispensers to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems existing in the metal containers used for fuel dispenser metering verification, such as the cumbersome and time-consuming adjustment method of the finger ring, the need for tools, and the difficulty in adjustment due to rust and jamming after long-term use, this utility model aims to provide a metal container for fuel dispenser metering verification with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a metal container for metering and verification of fuel dispensers, comprising: a bottle body, an oil level tube vertically disposed outside the bottle body, a scale fixed parallel to the oil level tube, and a finger ring movable along the scale and surrounding the outside of the oil level tube; the container also includes an adjustment mechanism for locking and unlocking the finger ring.

[0007] The adjustment mechanism includes a sliding block that is fixedly connected to the finger ring and slidably fitted to the scale. The sliding block has a cavity inside, and a rotating block is provided inside the cavity. One end of the rotating block is fixedly connected to a rotating shaft, and the other end of the rotating shaft is connected to a locking block via a coupling. The locking block can move radially under the drive of the rotating block to selectively engage or disengage with the scale, thereby achieving axial locking or unlocking of the sliding block.

[0008] Preferably, the container also includes a rotating mechanism, which includes a baffle that can be opened and closed to cover the top opening of the bottle, a support block fixed to the bottle, and a pressure rod with one end fixedly connected to the baffle. The pressure rod is rotatably connected to the support block via a rotating shaft, which solves the problem of needing to hold the bottle cap when refueling.

[0009] Preferably, in order to achieve reliable locking, the surface of the scale is provided with multiple slots distributed along its length. The head of the locking block is adapted to the shape of these slots. When the rotating block rotates, it can drive the head of the locking block to move out of or into the slot. This structure ensures the stability of the locking and the precise adjustment.

[0010] Preferably, in order to make the structure more compact and easier to operate, the sliding block has a cavity inside, and the rotating block and the rotating shaft are both accommodated in the cavity. At the same time, the operating end of the rotating block is exposed outside the sliding block. This design not only protects the internal transmission components, but also allows the operator to easily hold and rotate the operating end directly.

[0011] Preferably, as a stable pivot structure, the support block has a pivot groove on its opposite inner wall, and the pivot is a horizontal bar, the two ends of which are rotatably housed in the two pivot grooves, providing stable and reliable support for the flipping of the pressure bar.

[0012] Preferably, in order to achieve effortless lever opening, the middle part of the pressure rod is rotatably connected to the second pivot. By pressing the free end of the pressure rod, a effortless lever effect can be formed with the second pivot as the fulcrum, thereby easily lifting the baffle connected to the other end of the pressure rod.

[0013] Preferably, in order to free up hands during refueling, the inner wall of the support block is provided with a locking structure for holding. When the pressure rod drives the baffle to flip to the open position, its rod body can be elastically engaged with the locking structure of the support block, thereby reliably fixing the baffle in the open state.

[0014] Preferably, to ensure the synchronization of adjustment and the integrity of the structure, the finger ring and the sliding block are an integral structure formed by injection molding or welding. This design avoids possible loosening or relative displacement between the two, ensuring the accuracy of adjustment.

[0015] This utility model has the following beneficial effects: 1. This utility model, by setting an adjustment mechanism composed of a rotating block, a rotating shaft, a coupling and a locking block, can control the locking block to engage or disengage with the locking groove on the scale through a simple rotation operation. This solves the problems of complex adjustment process of the index ring of measuring containers in the prior art, the need for tools, and the easy jamming after long-term use, which leads to positioning difficulties. The index ring adjustment is fast, accurate and tool-free, which significantly improves the efficiency and convenience of the verification work.

[0016] 2. This utility model solves the problem that when refueling, the top cap of the container needs to be held by the operator's hand, which hinders the operation of the refueling gun with both hands, affects work efficiency, and poses safety hazards. It automatically keeps the bottle cap in the open state, frees the operator's hands, and improves the convenience and safety of refueling operation.

[0017] 3. This utility model integrates the quick adjustment mechanism with the self-locking bottle mouth rotation mechanism into one unit. The overall structure is ingeniously designed and has strong functional synergy. It solves the problems of the existing test container's single structural design and insufficient consideration of the continuity and humanization needs of on-site operation. The structure is compact, the function is practical, and the overall operation process is smoother and more efficient. Attached Figure Description

[0020] 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. Example

[0021] Please refer to Figures 1 to 5 This utility model provides a metal container for fuel dispenser metering verification, which aims to solve the problems of inconvenient adjustment of the finger ring 202 and the need for manual support after the bottle cap is opened in the existing metal containers for fuel dispenser metering verification.

[0022] like Figure 1 As shown, a metal container for measuring and verifying a fuel dispenser includes a bottle body 1 and an oil level tube 4 vertically disposed outside the bottle body 1. The bottle body 1 serves as a carrier for containing and measuring fuel, while the oil level tube 4 displays the liquid level inside the bottle body 1. A scale 201 is fixed to the bottle body 1 parallel to the oil level tube 4. A finger ring 202 surrounds the outside of the oil level tube 4 and is fixedly connected to a sliding block 203. The sliding block 203 is slidably engaged with the scale 201, allowing the finger ring 202 to move along the length of the scale 201. In a specific embodiment, the finger ring 202 and the sliding block 203 are an integral structure formed by injection molding or welding to ensure synchronous movement of the two during the adjustment process. The container also includes an adjustment mechanism 2 for locking and unlocking the position ring 202, see reference. Figure 2 and Figure 3 The detailed structure of the adjusting mechanism 2 is as follows: the sliding block 203 has a cavity inside, and the rotating block 204 and the rotating shaft 205 are both accommodated in the cavity of the sliding block 203; the operating end of the rotating block 204 is exposed outside the sliding block 203, and the other end of the rotating block 204 is fixedly connected to one end of the rotating shaft 205. The other end of the rotating shaft 205 is connected to the locking block 207 through the coupling 206; the surface of the scale 201 has multiple slots distributed along its length, and the head of the locking block 207 is adapted to the shape of these slots; when the rotating block 204 is rotated, it drives the locking block 207 to move radially through the rotating shaft 205 and the coupling 206, so that the head of the locking block 207 can selectively engage in the slots to lock the sliding block 203, or disengage from the slots to unlock the sliding block 203.

[0023] Please refer to Figure 1 , Figure 4 and Figure 5The rotating mechanism 3 includes a baffle 301 that can be opened and closed to cover the top opening of the bottle body 1, a support block 305 fixed to the top side wall of the bottle body 1, and a pressure rod 302. One end of the pressure rod 302 is fixedly connected to the side wall of the baffle 301, and the middle part of its rod is rotatably connected to the support block 305 through a second rotating shaft 303. A rotating shaft groove 304 is provided on the opposite inner wall of the support block 305. The second rotating shaft 303 is a horizontal bar, and its two ends are rotatably housed in the two rotating shaft grooves 304, providing a stable pivot for the flipping of the pressure rod 302. When the other end of the pressure rod 302 is pressed, a lever effect is formed with the second rotating shaft 303 as the fulcrum, thereby lifting the baffle 301 connected to the pressure rod 302 and opening the opening of the bottle body 1.

[0024] The inner wall of the support block 305 is also provided with a locking structure for holding; when the pressure rod 302 drives the baffle 301 to flip to the fully open position, the rod part of the pressure rod 302 can engage with the locking structure on the inner wall of the support block 305; this flip-open-locking structure ensures that the baffle 301 can be stably kept in the open state without manual support, thus freeing the operator's hands.

[0025] As a preferred embodiment, in order to achieve reliable locking, refer to Figure 2 and Figure 3 The surface of the scale 201 is provided with a plurality of slots distributed along its length direction. The head shape of the locking block 207 is adapted to the shape of the slot. This adapted structure ensures that the head of the locking block 207 can provide a stable axial limit after being locked into the slot.

[0026] As another preferred embodiment, for ease of use by the operator, refer to Figure 2 and Figure 3 The sliding block 203 has a cavity inside, and the rotating block 204 and the rotating shaft 205 are both accommodated in the cavity. The operating end of the rotating block 204 is designed to be exposed outside the sliding block 203, so that the operator can directly hold and rotate the exposed operating end.

[0027] As another preferred embodiment, to ensure the stability and durability of the rotating mechanism 3, refer to Figure 4 and Figure 5 The support block 305 has a pivot groove 304 on its opposite inner wall. The pivot 303 is a horizontal bar, and its two ends are rotatably housed in the two pivot grooves 304. This structure provides a stable pivot support for the flipping of the pressure rod 302.

[0028] As another preferred implementation, in order to achieve a labor-saving opening operation, refer to Figure 4The middle part of the rod of the pressure rod 302 is rotatably connected to the second rotating shaft 303. One end of the rod is fixed to the baffle 301, and the other end is a free end. By pressing the free end, a lever effect can be formed, and the baffle 301 can be lifted with little effort.

[0029] As a more specific implementation, in order to reliably fix the baffle 301 in the open position, refer to... Figure 5 The inner wall of the support block 305 is provided with a snap-fit ​​structure for holding. When the pressure rod 302 drives the baffle 301 to flip to the open position, its rod part can be elastically engaged with the snap-fit ​​structure of the support block 305, thereby achieving temporary fixation of the open state.

[0030] Working principle: When the position of the finger ring 202 needs to be adjusted, firstly, the rotating block 204 exposed outside the sliding block 203 is operated to rotate it. The rotating block 204 drives the locking block 207 to move radially through the fixedly connected rotating shaft 205 and coupling 206, so that its head is completely moved out of the slot on the surface of the scale 201. At this time, the axial lock of the sliding block 203 is released. Then, the operator can directly drive the sliding block 203, which is fixedly connected to the finger ring 202, to move up and down along the length of the scale 201 to the new target position. After moving to the position, the rotating block 204 is operated in reverse so that the locking block 207 is re-engaged into the slot of the corresponding height. The sliding block 203 is locked firmly again, thus completing the quick and tool-free adjustment of the finger ring 202. Through the synergistic action of the adjustment mechanism 2, this utility model solves the problems of inconvenient adjustment process and difficulty in adjustment due to long-term placement of the finger ring 202 in the existing structure. When refilling the bottle 1, first press the free end of the pressure rod 302, which is fixedly connected to the baffle 301. The pressure rod 302 rotates around the pivot 303, causing the baffle 301 at its other end to flip upward, thereby opening the top opening of the bottle 1. When the baffle 301 is fully open, the rod part of the pressure rod 302 can be engaged with the locking structure on the inner wall of the support block 305, temporarily fixing the open state. After refilling, simply move the pressure rod 302 gently to disengage it, and the baffle 301 can be closed by gravity or by manual reset. Through the coordinated action of the rotating mechanism 3, this utility model solves the problem that the existing bottle 1 oil inlet requires constant hand support after opening, which hinders the refilling operation.
