Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in conjunction with the embodiments.

[0022] Embodiment 1

[0023] See Figures 1 - 4The present embodiment provides a flange sleeve with a neck ring weld, including a flange sleeve body 1. The outer surface of the flange sleeve body 1 is provided with a welding ring, a welding hole and a reinforcing rib, which is a structure provided by the flange sleeve body 1. The welding ring and the welding hole are used to fix the pipeline in the flange sleeve body 1. The reinforcing rib plays a role in strengthening the stability of the structure. The outer surface of the flange sleeve body 1 is fixedly connected with a reinforcing steel plate 2. The outer surface of the flange sleeve body 1 is provided with a clamping assembly 3. The clamping assembly 3 includes a support sheet 301. The support sheet 301 is fixedly connected to the outer surface of the reinforcing steel plate 2. There are two support sheets 301. A swing bar 303 is rotatably connected between the two support sheets 301 through a rotating shaft 302. A screw 304 is rotatably connected above the swing bar 303. A clamping plate 305 is provided on the threaded sleeve on the outer surface of the screw 304. The clamping assembly 3 also includes a sliding The sliding piece 306 is fixedly connected to the lower part of the clamping plate 305, and the sliding piece 306 is slidably connected to the outer surface of the swing bar 303. There are two groups of clamping components 3, and the two groups of clamping components 3 are symmetrically arranged on the left and right sides of the flange sleeve body 1. A reinforcing ring plate 5 is fixedly connected to the outer surface of the flange sleeve body 1, and the reinforcing ring plate 5 is fixedly connected to the upper part of the reinforcing steel plate 2. The reinforcing steel plate 2 and the reinforcing ring plate 5 are welded to the outer surface of the flange sleeve body 1 to strengthen the structure of the flange sleeve body 1 and make it have higher strength. A pad 6 is fixedly connected to the outer surface of the reinforcing ring plate 5, and the pad 6 is movably fitted with the sliding piece 306. The pad 6 is used to support the sliding piece 306. At this time, the swing bar 303 is slightly tilted to the outside and can be flipped downward under the action of gravity until it droops. A limiting component 4 is arranged on the front of the flange sleeve body 1.

[0024] When the above-mentioned device is used in practice, when it is necessary to connect another flange under the flange sleeve body 1, first place the other flange under the flange sleeve body 1 and fit them together. At this time, release the fixing of the clamping assembly 3 by the limit assembly 4. Since the gasket 6 will support the sliding plate 306 in a normal state, causing the swing bar 303 to tilt slightly outward, the swing bar 303 will sag under the action of gravity, causing the rotating shaft 302 to rotate on the supporting plate 301, and the clamping plate 305 on the swing bar 303 will clamp the lower edge of the flange plate of the other flange. At this time, the screw 304 is rotated to drive the clamping plate 305 to move toward the swing bar 303, so as to clamp the other flange under the flange sleeve body 1, thereby providing support, so that the two can be firmly connected using bolts later.

[0025] Embodiment 2

[0026] See also Figures 1 - 4, on the basis of the first embodiment, the limiting component 4 includes a support base 401, the support base 401 is fixedly connected to the front surface of the flange sleeve body 1, the left and right sides of the support base 401 are fixedly connected with support plates 402, a limiting arm 404 is rotatably and elastically connected above the support plates 402 through a torsion spring 403, the torsion spring 403 applies a torsion force in the normal state to make the limiting arm 404 fit with the flange sleeve body 1, a limiting piece 405 is fixedly connected above the limiting arm 404, the limiting piece 405 is movably fitted with the outer surface of the swing bar 303, the number of the support plates 402, the torsion spring 403, the limiting arm 404 and the limiting piece 405 is two, which are symmetrically arranged on the left and right sides of the support base 401 respectively, the limiting component 4 further includes a handle 406, the handle 406 is fixedly connected above the limiting arm 404, the shape of the handle 406 is L-shaped, and the number of the handles 406 is two.

[0027] When the above-mentioned device is in specific use, when it is necessary to release the fixation of the clamping component 3 by the limiting component 4, first pinch the two handles 406 to make them approach each other, the handles 406 will drive the two limiting arms 404 to open, so that the limiting piece 405 leaves the swing bar 303. At this time, the swing bar 303 will sag under the action of gravity. After the swing bar 303 sags, by releasing the two handles 406, the torsion spring 403 will apply a torsion force to make the limiting arm 404 move towards the flange sleeve body 1, and the limiting arm 404 will press on the sliding piece 306 on the swing bar 303, so that the swing bar 303 fits the side surface of another flange, so as to facilitate the clamping plate 305 on the swing bar 303 to clamp another flange.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
