It is mainly used to firmly connect the upper shell of the gas meter with the pipeline or other components. During assembly, the upper shell needs to be placed on the mold, and then the rivet joint is placed at the interface at the top of the upper shell, and the rivet joint and the upper shell are welded.
[0003] When using a processing mold device to weld the rivet head and the upper shell, in order to ensure that the upper shell does not shake during the welding process, the mold for placing the upper shell is usually tightly fitted with the inner wall of the upper shell. This will cause some deviations in the angle between the upper shell and the mold during the placement process. When the upper shell is taken out, it will cause wear on the inner wall of the upper shell, affecting the use of the upper shell. Utility Model Content

When the ends of the two conical blocks approaching each other contact the outer surfaces of the two sliding rods, the bottom ends of the two sliding rods will be pushed to slide on the inner wall of the first sliding groove, and the top ends will slide on the inner wall of the through groove to move away from each other and compress the spring, so that the rectangular blocks at one end of the two sliding rods are pressed against the inner wall of the upper shell, and the position of the upper shell on the outer surface of the base is fixed. After the welding is completed, the screw is rotated to make the two conical blocks move away from each other, and the spring on one side of the sliding rod will return to its original state and push the sliding rod to move in the direction of the screw to drive the rectangular block to return to its original position.
[0007] Preferably, the edge of one end of the conical block is arc-shaped, and the sliding rod is composed of two cylindrical rods perpendicular to each other.

The bottom end of the sliding rod 25 slides on the inner wall of the first slide groove 24, and one end of the sliding rod 25 is fixedly connected to a rectangular block 26. A spring 27 is provided on one side of the sliding rod 25, and the two ends of the spring 27 are respectively fixedly connected to one side of the sliding rod 25 and one side of the inner wall of the through groove 21. By providing the rectangular block 26, when the upper shell is welded to the rivet joint, the upper shell is sleeved on the outer surface of the base 6 and the interface at the top of the upper shell is aligned with the two round blocks at the top of the base 6, and then the screw is turned. The rod 22 controls the two conical blocks 23 to move toward the middle of the screw rod 22 on the outer surface of the screw rod 22. When the ends of the two conical blocks 23 approaching each other contact the outer surfaces of the two sliding rods 25, the bottom ends of the two sliding rods 25 are pushed to slide on the inner wall of the first slide groove 24, and the top ends are pushed on the inner wall of the through groove 21 to move away from each other and compress the spring 27, so that the rectangular blocks 26 at one end of the two sliding rods 25 are pressed against the inner wall of the upper shell, and the position of the upper shell on the outer surface of the base 6 is fixed. After welding is completed, the screw rod 22 is rotated to move the two conical blocks 23 away from each other. The spring 27 on one side of the sliding rod 25 will return to its original state and push the sliding rod 25 to move in the direction of the screw 22 to drive the rectangular block 26 to return to its original position. By setting the fastening device 2, the upper shell is placed on the outer surface of the base 6, and the position of the conical block 23 is adjusted by rotating the screw 22 to control the movement of the sliding rod 25.

[0031] Reference Figure 2-6As shown, in this embodiment: the edge of one end of the conical block 23 is arc-shaped, and the sliding rod 25 is composed of two mutually perpendicular cylindrical rods. By setting the edge of one end of the conical block 23 to be arc-shaped and the sliding rod 25 to be a cylindrical rod, the outer surface of the conical block 23 contacts the outer surface of the sliding rod 25, making it easier to push the sliding rod 25 to move, and the sliding rod 25 is not easily stuck between the two conical blocks 23 and unable to move. A round rod 28 is fixedly connected to one side of the sliding rod 25, and the outer surface of the round rod 28 slides on the inner wall of the through groove 21. When the sliding rod 25 is controlled to move, the round rod 28 on one side of the sliding rod 25 will also slide on the inner wall of the through groove 21, further limiting the angle between the sliding rod 25 and the base 6, and avoiding shaking of the sliding rod 25 when it moves as much as possible.
[0032] Reference Figure 2-6 As shown, in this embodiment: the diameter of the round rod 28 is slightly smaller than the inner diameter of the spring 27, and the spring 27 is sleeved on the outer surface of the round rod 28.
