[0024] Please refer to Figures 1 to 7 , the present utility model provides a technical solution:

[0025] A convenient device for the inner welding pipe flange of a vacuum cavity, including a first flange 1 and a second flange 2. Symmetrically and fixedly connected to the outside of the first flange 1 is a fixed seat 4. Inside the fixed seat 4 is a slidably connected adjusting plate 12. Inside the fixed seat 4 is a rotatably connected lead screw 13. The adjusting plate 12 is threadedly connected to the lead screw 13. Fixedly connected to the bottom of the adjusting plate 12 is a connecting rod 7. Fixedly connected to one side of the connecting rod 7 is a pressing rod 11. Symmetrically and fixedly connected to the outside of the second flange 2 is a connecting seat 3. Inside the connecting seat 3 is an inclined groove 5 that cooperates with the pressing rod 11. During use, by rotating the lead screw 13, the adjusting plate 12 is driven to move. The adjusting plate 12 drives the pressing rod 11 to move downward into the inclined groove 5 through the connecting rod 7, so that the pressing rod 11 squeezes and drives the connecting seat 3 to slide. The connecting seat 3 drives the second flange 2 to move, thereby fully tightening the flanges and achieving an anti-loosening effect.

[0026] Further, a limiting rod 14 is fixedly connected inside the fixed seat 4, and the adjusting plate 12 is slidably connected to the limiting rod 14. The arrangement of the limiting rod 14 can limit the movement of the adjusting plate 12 to prevent deviation.

[0027] Further, a limiting groove 6 for cooperating with the connecting seat 3 is formed inside the fixed seat 4. The arrangement of the limiting groove 6 can cooperate with the connecting seat 3 to facilitate the connection between the flanges.

[0028] Further, a worm 17 is rotatably connected inside the fixed seat 4. A worm gear 16 that cooperates with the worm 17 is fixedly connected to the outer side of the lead screw 13. One end of the worm 17 is fixedly connected to a handle 9. By driving the handle 9 to rotate, the worm 17 drives the lead screw 13 to rotate through the worm gear 16, facilitating the adjustment of the position of the adjusting plate 12.

[0029] Further, a fixed block 8 is fixedly connected to one side of the fixed seat 4. A plug rod 15 is slidably connected inside the fixed block 8. Slots 10 for cooperating with the plug rod 15 are equidistantly formed inside the handle 9. The position of the handle 9 can be locked by moving the plug rod 15 into the inside of the slots 10 to prevent accidental touch.

[0030] Further, a slider 19 is fixedly connected to the outer side of the plug rod 15. The slider 19 is slidably connected to the fixed seat 4. A spring 18 is sleeved on the outer side of the plug rod 15 and on one side of the slider 19. The spring 18 drives the slider 19 to move and reset. The arrangement of the slider 19 can limit the movement of the plug rod 15 to prevent deviation.

[0031] During use, when it is necessary to connect the first flange 1 and the second flange 2, the connecting seat 3 is pushed into the inside of the limiting groove 6, thereby playing a positioning function and facilitating the subsequent connection of the flanges through bolts. Rotate the handle 9, and the handle 9 drives the worm 17 to rotate. The worm 17 drives the lead screw 13 to rotate through the worm gear 16. The rotation of the lead screw 13 drives the adjusting plate 12 to move. The arrangement of the limiting rod 14 can limit the movement of the adjusting plate 12 to prevent deviation. The adjusting plate 12 drives the pressing rod 11 to move downward into the inclined groove 5 through the connecting rod 7, so that the pressing rod 11 squeezes and drives the connecting seat 3 to slide. The connecting seat 3 drives the second flange 2 to move, so as to fully tighten the flanges and achieve an anti-loosening effect. Subsequently, the flanges can be further connected through bolts to further achieve an anti-loosening effect and facilitate use.
