DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figure 1 The utility model provides a technical solution: a ring forging with a sealing structure.

[0025] Among them, the flange 4 is arranged inside the upper protective sleeve 1 and the lower protective sleeve 2, and the inner cavity side walls of the upper protective sleeve 1 and the lower protective sleeve 2 are opened with mounting holes 103, and a hollow sleeve 301 is fixedly connected inside the mounting hole 103, a movable pin 302 is inserted inside the hollow sleeve 301, and a pad 1 303 is fixedly connected to the top of the movable pin 302. A spring 1 304 is arranged between the side wall of the upper protective sleeve 1 and the fixed plate 3, and a spring 2 305 is arranged between the pad 1 303 and the fixed plate 3. The spring 1 304 and the spring 2 are both sleeved on the outside of the hollow sleeve 301, and a fixed plate 3 is arranged on the outside of the hollow sleeve 301.

[0026] In this embodiment, a semicircular inner cavity is provided in the upper protective sleeve 1 and the lower protective sleeve, which can be embedded in the flange 4. In the mounting hole 103, the hollow sleeve 301 is directly welded to the side wall of the upper protective sleeve 1 at the bottom of the mounting hole 103. A hole is opened in the center of the hollow sleeve 301, and the diameter at the opening is smaller than the inner diameter. The movable pin 302 is circular like the hollow sleeve 301. The bottom diameter of the movable pin 302 is larger than the diameter at the middle position. The bottom is embedded in the center hole of the hollow sleeve 301 and can move in the center hole. The smaller diameter at the opening can prevent the movable pin 302 from falling out. 2 moves, the distance between the pad 1 303 at the front end and the center of the upper protective sleeve 1 will change, and the fixed plate 3 sleeved on the hollow sleeve 301 changes its position in the upper protective sleeve 1 by squeezing and releasing the spring 1 304 on one side, and the spring 2 305 between the pad 1 303 and the inner side of the fixed plate 3 adjusts the position of the pad 1 303 to the center of the upper protective sleeve 1 by squeezing and releasing, so that flanges 4 of different sizes can be inserted into the fixed plate 3 and fixed by spring squeezing, and when the flange 4 or the protective sleeve shakes, the contraction and release of the two springs can reduce the impact on each other.

[0027] The protective layer 104 is evenly distributed on the inner cavity side walls of the upper protective cover 1 and the lower protective cover 2 .

[0028] In this embodiment, the protective layer 104 can absorb moisture in the air to slow down the oxidation of the flange 4, thereby protecting the flange 4 and extending the service life of the flange 4.

[0029] The fixing plate 3 is U-shaped, and a backing plate 2 306 is disposed on the other side of the backing plate 1 303 on the inner side of the fixing plate 3 .

[0030] In this embodiment, the backing plate 1 303 and the backing plate 2 306 are respectively arranged on both sides of the flange 4 to clamp the flange and reduce the friction between the fixing plate 3 and the flange.

[0031] The upper protective cover 1 and the lower protective cover 2 are plugged with a rotating shaft 101 on their left sides, and the upper protective cover 1 and the lower protective cover 2 are both provided with a docking hole 102 on their right sides.

[0032] In this embodiment, the upper protective cover 1 and the lower protective cover 2 rotate around the rotating shaft 101 to open or close the inner cavity. When the upper protective cover 1 and the lower protective cover 2 are docked and merged, the docking holes 102 are aligned, and the two protective covers are locked by tightening the screws on the docking holes 102 to make them airtight.

[0033] The upper protective cover 1 and the lower protective cover 2 are made of forging materials.

[0034] In this embodiment, the forging has low impurities and higher strength, which can better protect the flange 4 from external impact.

[0035] There are two mounting holes 103 in the upper protective cover 1 and the lower protective cover 2, and they are located on the left and right sides.

[0036] In this embodiment, the structures of the fixing plates 3 in the upper protective cover 1 and the lower protective cover 2 are the same, and the mounting holes 103 are distributed on the left and the right and are located one front and one back. In this way, the fixing plates 3 at four locations are staggered with each other, and the two springs are distributed on different sides. The elastic force of the springs stretches the flange 4 so that it is always in the middle position in the protective cover.

[0037] Working principle: the upper protective sleeve 1 rotates along the rotating shaft 101 to open the inner cavity, the flange 4 is inserted between the gasket 1 303 and the gasket 2 306, the spring 1 304 and the spring 2 305 are compressed, and the four fixing plates 3 cooperate to fix the flange 4 at the center position of the upper protective sleeve 1 and the lower protective sleeve 2. When the flange 4 moves, the friction between the flange 4 and the upper protective sleeve 1 and the lower protective sleeve 2 is reduced through the unloading force of the four springs, thereby extending the service life of the protective sleeve. At the same time, the inner side of the upper protective sleeve 1 and the lower protective sleeve 2 is coated with a protective layer 104, which can absorb moisture in the air to slow down the oxidation degree of the flange 4, thereby protecting the flange 4 and extending the service life of the flange.
