Description

Technical Field

[0001] This utility model relates to the field of automotive refueling pipe sealing technology, specifically to a sealing tooling for automotive refueling pipes. Background Technology

[0002] After the automotive refueling hose is manufactured, it needs to undergo an airtightness test, which requires sealing its end. Since the surface to be sealed on the automotive refueling hose is irregular, traditional surface sealing methods cannot effectively seal it. Moreover, the area around the end of the automotive refueling hose is very small, with only a small outer flange. Therefore, existing sealing structures are difficult to fix at the end. Thus, designing a sealing fixture for automotive refueling hoses is particularly important to solve the above problems. Summary of the Invention

[0003] To solve the above problems, this utility model designs a sealing fixture for automotive refueling pipes. By using a three-claw locking assembly in conjunction with the flange around the automotive refueling pipe, it can be used normally even with a small force point. Furthermore, the structure provides better connection stability after hooking, thus increasing its practicality.

[0004] To solve the above-mentioned technical problems, this utility model provides a sealing fixture for automotive refueling pipes, characterized in that it includes a three-jaw mounting plate, a three-jaw guide plate, a sealing structure, and a locking assembly. The three-jaw mounting plate is provided with a locking assembly drive mechanism, which passes through the three-jaw mounting plate and connects to the three-jaw guide plate. The sealing structure is detachably installed at the bottom of the three-jaw guide plate. The locking assembly consists of three connecting rods and hook-shaped locking parts respectively installed at the lower ends of the three connecting rods. The upper ends of the three connecting rods are movably connected to the three-jaw mounting plate via a first connecting assembly. The three-jaw guide plate is respectively connected to the three connecting rods via three second connecting assemblies. The connecting rods have through grooves for connecting the second connecting assemblies, which can slide along the through grooves.

[0005] Furthermore, the locking assembly drive mechanism includes a handle, a drive frame, a connecting frame, a drive shaft, an upper limit block, and a lower limit block. The upper end of the drive shaft passes through the three-jaw mounting plate and the upper limit block in sequence and extends into the connecting frame to connect with the drive frame. The handle is installed at one end of the drive frame. The drive frame is movably connected to the upper end of the connecting frame. The lower end of the connecting frame is connected to both sides of the upper limit block. The lower limit block is connected to the drive shaft below the three-jaw mounting plate. The lower end of the drive shaft is connected to the center of the top of the three-jaw guide plate.

[0006] Furthermore, the lower limit block is a limit nut, the drive shaft is provided with an external thread relative to the lower limit block, and the bottom of the three-jaw mounting plate is provided with a limit groove that matches the lower limit block.

[0007] Furthermore, the connecting frame is composed of two connecting side plates and a front baffle for connecting the two connecting side plates, and the front baffle is integrated with the two connecting side plates.

[0008] Furthermore, the sealing structure consists of a clamping end that matches the end of the car's fuel filler pipe and a silicone rubber plug that seals against the inner wall of the end of the car's fuel filler pipe. The clamping end is detachably mounted on the bottom of the three-jaw guide plate, and the silicone rubber plug is detachably mounted on the bottom of the clamping end.

[0009] After adopting the above structure, the present invention has the following beneficial effects: 1. This utility model adopts a three-claw locking component in conjunction with the flange around the car refueling pipe, which can be used normally even when the force point is small. Moreover, the connection stability is better after the structure is hooked, which increases the practical performance.

The lower end of the connecting frame is connected to both sides of the upper limit block. The lower limit block is connected to the drive shaft below the three-jaw mounting plate. The lower end of the drive shaft is connected to the center of the top of the three-jaw guide plate. This design increases the radial force through the locking assembly drive mechanism, ensuring a tight seal between the sealing surfaces.

[0023] like Figure 4 The lower limit block shown is a limit nut. The drive shaft is provided with an external thread relative to the lower limit block. The bottom of the three-jaw mounting plate is provided with a limit groove that matches the lower limit block.
