Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0045] Embodiment one

[0046] Referring to Figures 1-5 A kind of high-durability pressure vessel, including main body assembly 1;The main body assembly 1 includes: pressure vessel body 11, the top of which is connected with pipeline 12 through;Sealing cover 13, is set to the top of the pipeline 12;The pipeline 12 and the sealing cover 13 are provided with fixed assembly 2, the fixed assembly 2 includes: fixed seat 211, is set to the top of the sealing cover 13;Fixed frame 21, fixedly connected to the outer side wall of the fixed seat 211;Extension plate 22, slidingly connected to the side of the fixed frame 21 away from the fixed seat 211;Screw 221, is set to the fixed frame 21 and the extension plate 22;Movable plate 23, is connected to the extension plate 22 through and slidingly;Through slot 24, is symmetrically set to the side wall of the movable plate 23 away from the fixed seat 211;Fixed block 25, fixedly connected to the bottom of the movable plate 23;Support 261, fixedly connected to the top of the extension plate 22;Spring one 26, one end fixedly connected to the side of the support 261 close to the movable plate 23;Limiting block 27, fixedly connected to the other end of the spring one 26;Pull rod 271, one end fixedly connected to the end of the limiting block 27 away from the movable plate 23, the spring one 26 is set on the outside of the pull rod 271, the other end is connected to the support 261 through and slidingly. Except the fixed seat 211 in the fixed assembly 2, the rest of the structure is symmetrically provided with multiple groups along the circumference of the fixed seat 211, and at least two groups are provided. The top of the extension plate 22 is fixedly connected with frame body 4, and the frame body 4 is set on the outside of the limiting block 27 and the spring one 26.

[0047] In use, after the worker completes the sealing cover 13 on the pipe 12 with bolt fixation, the worker adjusts the length of the extension plate 22 according to the diameter of the sealing cover 13: unscrew the screw 221, and pull out the extension plate 22 to the outside, when the pulled-out length is convenient for moving the movable plate 23 and the fixed block 25 to the outside of the sealing cover 13, stop pulling out the extension plate 22, and tighten the screw 221, complete the fixation between the fixed frame 21 and the extension plate 22, place the fixed seat 211 on the top of the sealing cover 13, and the movable plate 23 and the fixed block 25 are around the outside of the sealing cover 13, adjust the distance of the extension plate 22 by screwing the screw 221, so that the inside of the movable plate 23 abuts against the outside wall of the sealing cover 13, then pull up the movable plate 23, when the groove on the movable plate 23 passes through the limiting block 27, the limiting block 27 is pushed to the support 261 direction, the spring one 26 is compressed, which is convenient for the upward movement of the movable plate 23, when the top of the fixed block 25 abuts against the bottom of the sealing cover 13, stop pulling the movable plate 23, at this time the spring one 26 pops the limiting block 27 into the through slot 24, the limiting block 27 limits the movable plate 23, and completes the fixation of the position of the fixed block 25, at this time the fixed block 25 and the extension plate 22 on the top are combined to clamp and fix the sealing cover 13, avoid the loosening of the bolt on the sealing cover 13 affecting the sealing of the inside of the pressure container body 11, avoid the early scrap of the pressure container body 11, and increase the durability of the pressure container body 11. When it is necessary to disassemble the fixed assembly 2, the worker pulls out the pull rod 271 to the outside, the pull rod 271 drives the limiting block 27 to disengage from the through slot 24, the fixed block 25 moves downward and releases the extrusion to the sealing cover 13, then the combined length of the fixed frame 21 and the extension plate 22 is increased by unscrewing the screw 221, which is convenient for taking off the extension plate 22 and the fixed frame 21 from the sealing cover 13. The multiple groups of fixed assemblies 2 outside the fixed seat 211 increase the contact area of the extension plate 22 and the fixed block 25 with the sealing cover 13, and enhance the fixation effect. Because the spacing of the fixed block 25 is adjusted when the extension plate 22 moves, the device is convenient for adapting to the fixation of sealing covers 13 with different diameters. The frame 4 outside the spring one 26 and the limiting block 27 guides the limiting block 27 when it moves, avoids the skewing of the limiting block 27 when it moves, and thus affects the limiting effect of the limiting block 27 on the movable plate 23.

[0048] Embodiment two

[0049] According to the basis of embodiment one, an auxiliary function is added.

[0050] Reference Figures 1-5The fixed seat 211 is provided with a linkage assembly 3 on the movable plate 23, the linkage assembly 3 comprises: a spring two 31 fixedly connected to the top of the fixed seat 211, a connecting rod 32 fixedly connected to the top of the spring two 31, a pull ring 33 fixedly connected to the top of the connecting rod 32, and a connecting plate 34 symmetrically and fixedly connected to the outer side wall of the connecting rod 32, and one end of the connecting plate 34 away from the connecting rod 32 is connected with the movable plate 23. The linkage assembly 3 further comprises a dovetail block 35 fixedly connected to the top of the movable plate 23, and the bottom of the connecting plate 34 is provided with a dovetail groove 36, and the dovetail block 35 is slidably connected in the dovetail groove 36. The top of the fixed block 25 is provided with an antiskid pad 251.

[0051] The linkage assembly 3 realizes the effect that multiple movable plates 23 are pulled together: after the staff adjusts the extension lengths of multiple extension plates 22, the staff pulls up the pull ring 33, the pull ring 33 drives the connecting rod 32 to move upwards, the spring two 31 is stretched, the connecting plate 34 fixedly connected outside the spring two 31 drives the movable plate 23 to move upwards at the same time, so that the movable plate 23 can be conveniently adjusted and fixed in time, the operation convenience is improved, when the pull rod 271 is pulled to release the limiting of the movable plate 23, the spring two 31 in the stretched state drives the connecting rod 32 and the movable plate 23 to move downwards at the same time, so that the fixing of the fixed block 25 can be conveniently released at the same time. When the extension lengths of the extension plates 22 are adjusted, the position of the movable plate 23 changes, the movable plate 23 drives the dovetail block 35 at the top to slide in the dovetail groove 36, and the dovetail block 35 and the dovetail groove 36 facilitate the change of the position of the movable plate 23 without affecting the linkage effect of the connecting plate 34. When the fixed block 25 abuts against the bottom of the sealing cover 13, the antiskid pad 251 at the top increases the friction force when the fixed block 25 contacts the sealing cover 13, avoids the movement of the fixed block 25, and thus enhances the fixing effect.

[0052] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
