Description

Technical Field

[0001] This utility model relates to the technical field of fuel dispenser oil pipe sealing mechanism, and in particular to a fuel dispenser oil pipe ferrule sealing ring composite sealing anti-detachment mechanism. Background Technology

[0002] Gas pumps: These are commonly found at gas stations and are used to dispense fuel for cars, motorcycles, and other vehicles. These pumps typically include a metering device that accurately dispenses fuel based on the vehicle's tank capacity and the user's needs, while also incorporating safety mechanisms to prevent spills and leaks.

[0003] The friction between the sealing ring and the outer wall of the oil pipe after the sealing ring is compressed in the existing technology cannot prevent the water hammer effect or the impact force when the oil circuit is vibrated. Over time, the pipeline sealing structure fails and comes loose, resulting in oil leakage. Therefore, this utility model proposes a composite sealing anti-loosening mechanism for the oil pipe clamp sealing ring of the fuel dispenser to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, where the friction between the sealing ring and the outer wall of the oil pipe after the sealing ring is compressed cannot prevent the impact force of water hammer effect or vibration in the oil circuit. Over time, the pipeline sealing structure fails, detaches, and causes oil leakage. The proposed invention is a composite sealing anti-detachment mechanism for the oil pipe clamp sealing ring of the fuel dispenser.

[0013] As a preferred embodiment of this utility model, the anti-detachment mechanism includes: a control rod, a fixing frame, a positioning frame, a spring, and a fixing block;

[0014] The control lever is projected onto the outside of the fixed frame, which is fixedly connected to the interface. The positioning frame is slidably connected to the top of the control lever, and the positioning frame is fixedly connected to the spring. The spring is fixedly connected to the fixing block, and the fixing block is fixedly installed on the top of the control lever.

[0038] As a preferred embodiment of this utility model, the anti-detachment mechanism includes: a control rod (7), a fixing frame (8), a positioning frame (9), a spring (10), and a fixing block (11);

[0039] The control rod (7) is projected on the outside of the fixed frame (8). The fixed frame (8) is fixedly connected to the interface (1). The positioning frame (9) is slidably connected to the top of the control rod (7). The positioning frame (9) is fixedly connected to the spring (10). The spring (10) is fixedly connected to the fixing block (11). The fixing block (11) is fixedly installed on the top of the control rod (7). After the positioning frame (9) and the fixed frame (8) are engaged, the positioning frame (9) can connect the fixed frame (8) and the control rod (7) to block the movement of the control rod (7) on the fixed frame (8) and realize the positioning of the control rod (7). This allows the control rod (7) to position the extrusion ring (4). The extrusion ring (4) can then be stably placed on the mounting frame (6) to prevent the sealing ring (3) and the oil pipe (2) from separating from the interface (1).

[0040] As a preferred embodiment of this utility model, the unlocking mechanism includes: a rotating rod (12), a drive frame (13), and a push rod (14);

[0041] The rotating rod (12) is rotatably connected to the top of the control rod (7). The rotating rod (12) slides in contact with the drive frame (13). The drive frame (13) is fixedly connected to the positioning frame (9). The push rod (14) slides in contact with the rotating rod (12). After the push rod (14) is pushed, the push rod (14) can push the rotating rod (12) to rotate, so that the rotating rod (12) can squeeze the drive frame (13) to move. The drive frame (13) can then drive the positioning frame (9) to move to the right and disengage from the fixed frame (8), thereby unlocking the control rod (7). The control rod (7) can then release the extrusion ring (4) or even disengage from the extrusion ring (4) to disassemble the extrusion ring (4). This allows the sealing ring (3) and the oil pipe (2) to be disassembled, facilitating the disassembly and replacement of the oil pipe (2) and the seal.

[0042] As a preferred embodiment of this utility model, the outer side of the fixing frame (8) is provided with a plurality of positioning slots arranged at equal intervals, and a positioning block is fixedly installed on the positioning frame (9). The positioning block and the positioning slot can be detachably snapped together.

[0043] As a preferred embodiment of this utility model, a round block is fixedly installed on the side of each of the two bonding frames (5) that is far apart from each other. The round block slides in contact with the inner side of the control rod (7). The round rod is used to connect the control rod (7) and the bonding frame (5), so that when the control rod (7) rotates, it can drive the bonding frame (5) to slide on the mounting frame (6).

[0045] The working principle of this utility model is as follows: When it is necessary to disassemble and replace the oil pipe (2) at the interface (1), it is only necessary to push the push rod (14) on the two control rods (7). After the push rod (14) is pushed, the push rod (14) can push the rotating rod (12) to rotate, so that the rotating rod (12) can squeeze the drive frame (13) to move. The drive frame (13) can then drive the positioning frame (9) to move to the right and disengage from the fixed frame (8), thereby unlocking the control rod (7). The control rod (7) can then release the squeezing ring (4). Push the control lever (7) upwards to disengage it from the bonding frame (5) and the extrusion ring (4), thus disassembling the extrusion ring (4). This allows the sealing ring (3) and oil pipe (2) to be separated, facilitating the disassembly and replacement of the oil pipe (2) and the seal. After replacement, first insert the extrusion ring (4) into the outside of the sealing ring (3) and oil pipe (2), then insert the sealing ring (3) and oil pipe (2) into the inside of the interface (1). Then install the extrusion ring (4), first inserting the extrusion ring (4) into the inside of the sealing ring (3), and then... Insert the bonding frame (5) onto the mounting frame (6), then lower the control lever (7) to engage with the round block. At this point, rotate the control lever (7), which will pry the extrusion ring (4) into the inner side of the interface (1), squeezing the sealing ring (3). This will allow the sealing ring (3) to be squeezed between the interface (1) and the oil pipe (2), filling the gap between the oil pipe (2) and the interface (1), sealing the oil pipe (2) and the joint. The control lever (7) and the extrusion ring (4) can also be positioned using the control lever (7). Release the positioning frame (9) so that the positioning frame (9) can automatically engage with the fixed frame (8). After the positioning frame (9) and the fixed frame (8) are engaged, the positioning frame (9) can connect the fixed frame (8) and the control rod (7) to block the movement of the control rod (7) on the fixed frame (8) and realize the positioning of the control rod (7). This allows the control rod (7) to position the extrusion ring (4), and the extrusion ring (4) can be stably placed on the mounting frame (6) to prevent the sealing ring (3) and the oil pipe (2) from disengaging from the interface (1).
