[0003] However, the existing neck butt welding flanges are only connected together by bolts. Although this achieves the purpose of fixing, the bolts are prone to loosening after long-term use, thereby affecting the stability of the connection between the two flanges. Therefore, it is necessary to design a neck butt welding flange that increases the stability effect. Utility Model Content

[0026] 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.

[0027] Reference Figure 1-6 The utility model provides a necked butt welding flange with increased stability, comprising a first flange 1 and a second flange 2, wherein a threaded rod 7 is fixedly connected to the lower end of the first flange 1, a circular hole 9 is opened on the lower end surface of the second flange 2, the threaded rod 7 passes through the circular hole 9, and is slidably connected to the circular hole 9, and a nut 8 is threadedly connected to the circumferential surface of the threaded rod 7; a transmission mechanism 3 is provided at the upper end of the first flange 1, a clamping plate 4 and a fixing assembly are provided on the circumferential surface of the first flange 1, and the first flange 1 is respectively connected to the clamping plate 4 and the fixing assembly through the transmission mechanism 3.

[0028] Specifically, align the threaded rod 7 on the first flange 1 with the circular hole 9 on the second flange 2, so as to facilitate the threaded rod 7 to pass through the circular hole 9. After the threaded rod 7 passes through the circular hole 9, screw on the nut 8 and then tighten the nut 8. At this time, with the cooperation of the nut 8 and the threaded rod 7, the connection between the first flange 1 and the second flange 2 can be preliminarily fixed. Then, the transmission mechanism 3 is used to drive the clamping plate 4 to be clamped on the second flange 2. In this way, under the action of the clamping plate 4, the connection between the first flange 1 and the second flange 2 can be fixed for a second time, thereby increasing the stability of the connection between the two flanges. After the clamping plate 4 is clamped, the transmission mechanism 3 is limited by the fixing assembly, so that the clamping plate 4 is stably clamped on the second flange 2; when disassembly is required, the fixing assembly on the transmission mechanism 3 is released, and it is convenient to detach all the clamping plates 4 from the second flange 2 at the same time, thereby facilitating the separation of the second flange 2 from the first flange 1.

[0029] The transmission mechanism 3 includes a rotating disk 301, a sliding rod 302, a moving block 303, a sliding hole 304 and a sliding groove 305. The rotating disk 301 is rotatably connected to the circumferential surface of the upper end of the first flange 1. The sliding hole 304 is provided on the upper end surface of the rotating disk 301, and the sliding rod 302 is slidably connected inside the sliding hole 304; the upper end surface of the first flange 1 is provided with a sliding groove 305, and the moving block 303 is slidably connected inside the sliding groove 305. The upper end of the moving block 303 is fixedly connected to the sliding rod 302, and the side end of the moving block 303 is fixedly connected to the clamping plate 4. When working, by rotating the rotating disk 301, the sliding rod 302 can be driven to slide inside the sliding hole 304, and then the moving block 303 can be driven to slide inside the sliding groove 305. With the movement of the moving block 303, the clamping plate 4 can be driven to move, so as to facilitate the clamping of the clamping plate 4 with the second flange 2, or to separate the clamping plate 4 from the second flange 2.

[0030] The sliding holes 304 correspond to the sliding grooves 305 one by one, and the sliding holes 304 are inclined. During operation, as the rotating disk 301 rotates, all the moving blocks 303 can be driven to slide inside the sliding grooves 305 at the same time, thereby improving work efficiency.

[0031] The end face shape of the slide groove 305 and the end face shape of the moving block 303 are both T-shaped. During operation, since the end face shape of the slide groove 305 and the end face shape of the moving block 303 are both T-shaped, the movement of the moving block 303 can be limited, so that the moving block 303 can move smoothly.

[0032] The clamping plate 4 is L-shaped, and an inclined surface is provided at one end of the clamping plate 4 close to the second flange 2 . During operation, since the inclined surface is provided at one end of the clamping plate 4 close to the second flange 2 , it is convenient for the clamping plate 4 to be clamped on the second flange 2 .

[0033] The fixing assembly includes a fixing plate 5 and a locking bolt 6. The fixing plate 5 is fixedly connected to the circumferential surface of the rotating disk 301. The locking bolt 6 is threadedly connected to the inner surface of the fixing plate 5. During operation, the locking bolt 6 is rotated so that the locking bolt 6 is in close contact with the circumferential surface of the first flange 1. In this way, the fixing plate 5 is fixed, and the rotating disk 301 can be fixed, which helps to prevent the rotating disk 301 from rotating.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
